TECHNICAL FIELD

[0001] The present application relates to the technical field of automobiles, in particular to a portable automobile back door bicycle rack device. BACKGROUND

[0002] Currently, cycling is becoming increasingly popular among people. However, when we need to take a bicycle from one place to another, the traditional way of transporting a bicycle may not be convenient enough. To solve this problem, car-mounted bicycle racks have emerged. The automobile back door bicycle fixing rack is a device installed on the trunk or door of a car, used to carry a bicycle. It is a convenient way of transporting a bicycle, especially suitable for those who do not want to install a roof rack or disassemble the bicycle wheels. Automobile back door bicycle racks come in a variety of designs to accommodate different types and sizes of vehicles and bicycles. Usually made of metal materials, with a bracket fixed on the back door of the car, and adjustable clamps between the front and rear wheels of the bicycle to maintain the stability of the bicycle. Using a car-mounted back door bicycle rack can conveniently carry a bicycle on the back door of a car without the need for additional trailer racks or roof racks. It is suitable for most sedans, SUVs and small vans with back doors, and is relatively easy to install and remove.

[0003] When using a car-mounted back door bicycle rack, first of all, you need to make sure that the car-mounted back door bicycle rack is securely installed on the back door of the car, and that the clamps are properly fixed on the wheels of the bicycle. During driving, pay attention to the stability of the bicycle and the car-mounted back door bicycle rack, to ensure that the bicycle does not sway or slide. In addition, you also need to ensure that the bicycle does not block the tail lights or license plate of the car, in order to comply with the requirements of traffic regulations. Common back door bicycle racks include hanging style and platform style.

[0004] Hanging style back door bicycle racks suspend the frame of the bicycle from the rack and use straps to secure it, making the bicycle appear to be floating in the air. This design is simple and easy to use, suitable for most types of bicycles. However, since the bicycle is suspended from the trunk, it may have some impact on visibility and vehicle stability.

[0005] Platform style back door bicycle racks, on the other hand, use a platform or support to hold the bicycle, keeping it parallel to the car. This design provides more stable support. Platform style back door bicycle racks are suitable for various types of bicycles, including mountain bikes, road bikes and electric bikes. When choosing an automobile back door bicycle rack, the following factors need to be considered: vehicle model and size, bicycle type and quantity, installation and fixing method, and quality and durability. Also, pay attention to follow relevant safety specifications and installation guidelines when using, to ensure the safety of the bicycle and not to cause damage to the vehicle.

[0006] A trunk-mounted bicycle rack capable of quick disassembly, folding and storage is disclosed in Chinese Patent CN116729266A. The bicycle rack has a supporting state and a storage state. When the bicycle rack is in the supporting state, it is supported on the trunk of the car. When the bicycle rack is in the storage state, it is removed from the trunk of the car and stored in the trunk. This bicycle rack may partially block the license plate of the car. The bicycle rack is set too high, making it inconvenient to take and put the bicycle. SUMMARY

[0007] To overcome the shortcomings of the prior art, the present application provides a portable automobile back door bicycle rack device to achieve convenient bicycle taking and placing and avoid blocking the license plate.

[0008] To solve the above technical problems, the technical solution adopted by the present application is:

[0009] The portable automobile back door bicycle rack device comprises a support structure for fixing on the back door of the car and a bracket structure for fixing the bicycle, and further comprises a sliding structure for adjusting the height of the bracket, the bracket structure is arranged on the support structure through the sliding structure, and a locking structure is arranged between the sliding structure and the support structure.
