[0028] In order to fully understand the present application, detailed steps and detailed structures will be presented in the following description to illustrate the technical solution of the present application. The preferred embodiments of the present application are described in detail below. However, in addition to these detailed descriptions, the present application may also have other implementation methods.
[0029] Please refer to Figure 1-Figure 3 As shown, the present application discloses a vehicle towing device, one end of which is adapted to be fixedly mounted on a trailer, and the other end of which is adapted to be connected to a towed vehicle. Specifically, each towed vehicle has a tow ball. In this embodiment, for ease of description, the tow ball on the towed vehicle is referred to as a target tow ball, and the specifications of the target tow ball are not specifically limited.
[0030] The vehicle towing device includes a connecting body 1, a clamping member 2, and an elastic member 3. The connecting body 1 includes a mounting portion 11 and a connecting portion 12 connected to the mounting portion 11. The connecting portion 12 is used to connect to a vehicle body, in this case a trailer. The mounting portion 11 has a spherical clamping space 111 for clamping a target trailer ball. One end of the elastic member 3 is connected to the connecting portion 12, and the other end abuts the clamping member 2. The clamping member 2 is positioned on one side of the spherical clamping space 111 and is rotatably connected to the connecting vehicle body via a connecting shaft to clamp or release the target trailer ball within the spherical clamping space 111.
[0031] It should be noted that in this embodiment, the length of the connecting portion 12 is 1 / 3 of the length of the vehicle towing device. Setting the connecting portion 12 to be relatively short not only reduces the space occupied by the entire towing device, thereby reducing the distance between the two vehicles and avoiding problems with smooth passage in narrow areas or around corners, but also allows for connection to a wider range of trailer models due to its shorter length, eliminating the problem of being unable to connect to trailers with smaller mounting portions 11 due to a longer connecting portion 12.
[0032] When the target trailer ball of the towed vehicle needs to be installed on the traction device, a force is applied to the clamping member 2, and the clamping member 2 compresses the elastic member 3 to completely expose the spherical clamping space 111, so that the target trailer ball can enter the spherical clamping space 111. At this time, the force applied to the clamping member 2 is canceled, and the clamping member 2 returns to its original position under the action of the elastic member 3 to clamp and fix the target trailer ball located in the spherical clamping space 111.
[0033] Specifically, the clamping member 2 includes a clamping portion 21 with a curved clamping surface 211 adapted to mate with the target trailer ball. When the clamping member 2 engages the target trailer ball, the curved clamping surface 211 abuts and secures the target trailer ball. The curved clamping surface allows for a tight fit between the clamping surface and the target trailer ball. The larger contact area increases friction between the two, thereby enhancing the stability of the connection between the trailer and the towed vehicle.
[0034] The vehicle traction device also includes a reinforcement layer structure 4, which is sleeved on the outside of the connecting body 1 and forms a reinforcement cavity 41 between the reinforcement layer structure 4 and the connecting body 1. On the one hand, it can greatly improve the connection strength of the traction device, and on the other hand, it can also protect the connecting body 1 to prevent the connecting body 1 from being deformed and damaged due to collision.
[0035] It is worth noting that in this embodiment, the mounting portion 11, the connecting portion 12 and the reinforcing layer structure 4 are integrally formed, thereby reducing the number of welding points or connecting portions 12 generated by the split structure, reducing potential structural weaknesses, and improving the strength and durability of the entire device. In addition, the one-piece molding setting can also simplify the manufacturing process, reduce assembly steps, thereby reducing production costs and reducing manual operations and assembly errors, further improving production efficiency.
[0036] In this embodiment, the vehicle towing device also includes a handle 5 connected to the connecting shaft, allowing the user to more conveniently apply force to the clamping member 2. Specifically, the handle 5 includes a connecting section 51 and an extension 52 connected to the connecting section 51. The extension 52 is bent away from the connecting body 1. This arrangement allows the hand to avoid proximity to other components of the towing device during operation, reducing the risk of accidental pinching or collision, and improving operational safety. Furthermore, the bent extension 52 provides greater operating torque, allowing the user to apply greater force when clamping or releasing the tow ball, thereby ensuring a secure hold or rapid release of the tow ball and enhancing the device's usability.
[0037] More specifically, an anti-slip layer is provided on the handle 5. By increasing the surface friction, the user can hold the handle 5 more firmly when operating the handle 5, preventing the hand from slipping, thereby ensuring the stability and safety of the operation. Even in wet, greasy or other adverse environments, the anti-slip layer can effectively prevent the hand from slipping, reduce the risk of accidents during operation, and ensure the safety of the user.
[0038] The above is only a specific implementation of the present application. Any other improvements made based on the concept of the present application are considered to be within the scope of protection of the present application.
