[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] In the description of this utility model, it should be noted that the orientation or positional relationship indicated by terms such as "center", "up", "down", "left", "right", "vertical", "horizontal", "inner", and "outer" are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] A wall-mounted bicycle fixing device structure, such as Figures 1-4 As shown, the device includes a hook 1, a housing 2, a base 3, a hinge 4, a cam 5, a spring plate 6, and a connector 7. The base 3 is mounted and fixed to the upper part of the vehicle side wall. The hook 1 is connected to the hinge 4 through the connector 7. The hook 1, the hinge 4, and the connector 7 are rotatably fixed inside the base 3. The cam 5 is integrally welded to the hook 1 and rotates together with it. The spring plate 6 is fixed to the base 3. The cam 5 is provided with a first limiting boss 5-1, which cooperates with the groove of the spring plate 6 to limit the hook 1.

[0021] Specifically, the rotatable design of hook 1, hinge 4, and connector 7 allows hook 1 to rotate and fit close to the vehicle's side wall when not in use, significantly reducing the space occupied by the bicycle fixing device inside the vehicle. This solves the problems of traditional fixing devices protruding from the side wall, occupying a large space, and hindering the opening of the side top panel, thus improving space utilization. The overall welding and rotational movement of cam 5 and hook 1 not only enhances the structural stability of hook 1 but also achieves a limiting function for hook 1 through cooperation with spring plate 6, ensuring the stability and safety of the hook when fixing the bicycle. This makes fixing and releasing the hook easier and ensures the safety of the device when closed. The cooperation between the groove of spring plate 6 and the first limiting boss 5-1 on cam 5 achieves the limiting and fixing of hook 1, improving the safety and stability of the device. It also makes the opening and closing of the hook smoother and easier to control. The design of the entire device is simple and clear, and the connection and cooperation between the components are tight and reasonable, making the operation of the device simpler and easier, reducing the difficulty of operation for passengers, and improving the ease of use and practicality of the device. Meanwhile, the simple structure also facilitates the maintenance and upkeep of the device, and by reducing the protruding parts of the hook and providing a flexible opening / closing mechanism, it reduces the risk of passengers' heads hitting the hook, significantly improving the safety and comfort of passengers inside the rail vehicle, and enhancing passengers' trust and satisfaction with rail transit.

[0022] As a preferred embodiment of the above, such as Figures 1-4As shown, the cam 5 is provided with a plurality of first limiting bosses 5-1, and the number and position of the first limiting bosses 5-1 are adapted to the required stopping angle of the hook 1.

[0023] Specifically, by setting multiple first limiting bosses 5-1 on the cam 5, the hook 1 can be limited at different angles, allowing the hook 1 to stop at multiple preset positions as needed, thereby meeting different usage requirements. The design of multiple limiting bosses allows the opening and closing angles of the hook 1 to be adjusted more flexibly. The appropriate stopping angle can be selected according to the size, weight, and internal space of the bicycle to achieve the best fixing effect and space utilization. The cooperation between the multiple limiting bosses and the spring plate 6 can more firmly fix the hook 1, preventing it from shaking or falling off when subjected to force, thus improving the structural stability and safety of the entire device.

[0024] As a preferred embodiment of the above, such as Figures 1-4 As shown, the base 3 is also provided with a second limiting boss 3-1, which further limits the movement of the hook 1 toward the side wall of the vehicle by limiting the connecting piece 7.

[0025] Specifically, the design of the second limiting boss 3-1 effectively prevents the hook 1 from being unable to be pulled out or operated smoothly due to excessive proximity when rotated to a position close to the side wall of the vehicle. This ensures the operability and convenience of the hook 1 during use. Furthermore, the second limiting boss 3-1 ensures that the device does not excessively occupy the interior space of the vehicle during use, while also providing sufficient operating space for passengers, improving space utilization and passenger comfort. The second limiting boss 3-1 not only serves a limiting function but also enhances the stability and reliability of the structure by increasing the contact area with the connector 7, reducing wear and loosening problems caused by long-term use, and extending the service life of the device.

[0026] As a preferred embodiment of the above, such as Figures 1-4 As shown, the connector 7 is provided with a connecting arc surface 7-1 at the position limited by the second limiting boss 3-1.

[0027] Specifically, the design of the arc surface 7-1 of the connector effectively reduces the friction area and friction force between the connector 7 and the second limiting boss 3-1, which not only reduces wear but also extends the service life of the connector and the limiting boss, improving the durability of the entire device. The arc surface design makes the connector 7 rotate or move more smoothly, reducing jamming or resistance, which improves the smoothness and convenience of operation, making the pulling out and retracting of the hook 1 easier and more natural.

[0028] As a preferred embodiment of the above, such as Figures 1-4 As shown, the second limiting boss 3-1 is provided on the base 3 in two positions, upper and lower, respectively limiting the movement of the hook 1 from the upper and lower angles toward the side wall of the vehicle.

[0029] Specifically, by setting second limiting bosses 3-1 at the upper and lower positions of the base 3, the hook 1 is fully limited from both the upper and lower directions, effectively preventing the hook 1 from moving towards the side wall of the vehicle at any angle, ensuring the stability and safety of the device. The design of the two upper and lower second limiting bosses 3-1 not only plays a limiting role, but also enhances the structural strength of the entire device by increasing the contact area and support points with the connector 7, which helps to resist external impacts and vibrations and improves the durability and reliability of the device.

[0030] As a preferred embodiment of the above, such as Figures 1-4 As shown, the hook 1 is provided with a suspension area, and the suspension area is treated to prevent damage and slippage.

[0031] Specifically, the anti-damage treatment in the suspension area helps reduce wear on the hooks during bicycle suspension, while preventing the hooks from deforming or being damaged due to long-term stress, thus reducing maintenance costs. The anti-slip treatment ensures that the bicycle will not slip due to shaking or external forces during suspension, thereby avoiding potential safety hazards.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
