An automotive tent mainly refers to the outdoor equipment (top-mounted tent) installed on the roof of a car, which is used to provide a windproof, rainproof and sunproof sleeping space for self-driving camping. According to its type, it can be divided into three categories: soft-top manual, hard-top automatic and hydraulic semi-automatic. 

Core type and functional features:
Soft-top manual tent:
It adopts a folding design and needs to be manually unfolded. It is lightweight (about 3-5 kg), has a large internal space (can accommodate 2-4 people), but the setup process takes a relatively long time (about 10 minutes). 
Typical material: Water-resistant Oxford fabric with PU coating, with a waterproof rating of 2000-3000mm. Suitable for short-distance casual camping. 
Hardtop Automatic Tent:
Aluminum or ABS shell, one-button pop-up design, opens in 3 seconds, highly wind-resistant (can withstand winds of level 8), but has a small space (can accommodate only 2 people). 
Advantages: Best rain and moisture protection, suitable for off-road exploration. 
Hydraulic Semi-Automatic Tent:
Hydraulic rods for support, 3 seconds to complete setup, balancing convenience and capacity (2-3 people), shell made of ABS + ASA materials, high durability. 
Purchase Guide and Brand Recommendations
Purchase Tips:
Load Capacity: Must match the roof load capacity (normal vehicle ≥ 300kg, off-road vehicle ≥ 500kg), and prefer to choose aviation aluminum brackets. 
Scene Adaptation:
Family Camping: Choose a soft-top model with a large space (such as Mochi Holiday Dome, with a diameter of 4.5 meters). 
Extreme environment: Hard-shell models (such as the Extreme Rock ADAMAS compatible model). 
Compliance: After installation, the height should be no more than 0.5 meters. It is necessary to file a record and update the vehicle registration certificate. 
Highly cost-effective brand:
Sardine: Hydraulic fully automatic model (¥6590), waterproof Oxford fabric + high elasticity mattress, suitable for SUVs. 
Dreamdof: Straight-Frame Hydraulic Tent (¥4980), opens in 3 seconds, suitable for all seasons. 
Dachshund: Duke Series Hardtop Model (capacity for 4-5 people), with a honeycomb aluminum frame that offers strong wind resistance. 
Installation and Usage Notes
Installation Procedure:
First, install the roof luggage rack (requiring a high-strength crossbar), then secure the tent with bolts to ensure uniform weight distribution on the A/B/C pillars. 

Safety Reminder:
Avoid using soft-top tents in strong winds (above 7 levels) or during heavy rain to prevent the frame from deforming. 

Regularly check the tightness of the bolts to prevent them from loosening during driving.
