[0025] In order to make the technical solutions and advantages of the present utility model clearer and more understandable, the exemplary embodiments of the present utility model are further described in detail below with reference to the drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than an exhaustive list of all embodiments. And without conflict, the embodiments in the present utility model and the features in the embodiments can be combined with each other.
[0026] An embodiment of the present utility model provides a handle bracket 1. As Figure 1 shown, the handle bracket 1 includes a handle bracket main body 11. The handle bracket main body 11 is configured as a frame structure, which can not only ensure the strength of the handle bracket main body 11 but also reduce the weight of the handle bracket main body 11. The handle bracket main body 11 is used to fix the lock cylinder 2. Specifically, a mounting hole 15 is provided on the handle bracket main body 11. The mounting hole 15 communicates in the direction from the first side to the second side. As Figure 3 shown, during the installation of the lock cylinder 2, the lock cylinder main body 21 is inserted from the first side of the mounting hole 15 and extends in the direction of the second side, and is arranged in the mounting hole 15. According to the present application, a spring piece 12 is provided on the handle bracket main body 11. The first end of the spring piece 12 is fixed on the handle bracket main body 11, and the second end is a free end. A abutting portion 13 is provided on the handle bracket main body 11. The abutting portion 13 protrudes from the first side of the handle bracket main body 11. The abutting portion 13 and the second end of the spring piece 12 are arranged at intervals, and a clamping groove 14 is formed therebetween.
[0027] At the same time, an embodiment of the present utility model provides a lock cylinder 2. As Figure 2 shown, the lock cylinder 2 includes a lock cylinder main body 21. The lock cylinder 2 is fixed to the vehicle door main body through the handle bracket 1. The lock cylinder main body 21 has a cylindrical structure. As Figure 3 shown, after being connected to the handle bracket 1, the lock cylinder main body 21 is inserted into the mounting hole 15 of the handle bracket 1. According to the present application, a wing plate 22 is provided on the lock cylinder main body 21. The wing plate 22 extends outwardly away from the lock cylinder main body 21. A clamping block 23 is provided on the wing plate 22. After the lock cylinder 2 is installed on the handle bracket 1, the wing plate 22 is located on the first side of the handle bracket main body 11, and the clamping block 23 is used to be clamped into the clamping groove 14 of the handle bracket 1 to form a clamping fit.
[0028] It can be seen that the clamping block 23 extends into the clamping groove 14 and forms a clamping fit with the clamping groove 14, thereby defining the positions of the lock cylinder 2 and the handle bracket 1. This way of clamping connection has a simple assembly process and a firm fixing effect.
[0029] In one embodiment, a blocking plate 16 is provided on the first side surface of the abutting portion 13. The blocking plate 16 extends in the direction of the clamping groove 14. After the clamping block 23 is clamped into the clamping groove 14, the clamping block 23 is also located between the handle bracket main body 11 and the blocking plate 16. Thus, the clamping groove 14 has a clamping and fixing effect on the clamping block 23 in the circumferential direction of the lock core main body 21, while the handle bracket main body 11 and the blocking plate 16 form a limiting effect on the clamping block 23 in the first side to the second side direction. The above setting can ensure the stability of the clamping block 23, and further ensure the firm connection between the lock core 2 and the handle bracket 1. Preferably, a chamfer 24 is provided on the first side surface of the clamping block 23. The chamfer 24 is located at the second end of the clamping block. The chamfer 24 can ensure that the clamping block 23 can be smoothly inserted between the handle bracket main body 11 and the blocking plate 16.
[0030] In one embodiment, the elastic piece 12 is bent so that the free end of the elastic piece 12 protrudes toward the first side relative to the fixed end. During installation, first insert the lock core main body 21 into the installation hole 15, and then rotate clockwise with the axial center of the lock core main body 21 as the central axis, and then install the clamping block 23 into the clamping groove 14. During the rotation of the clamping block 23 driven by the wing plate 22, the clamping block 23 first contacts the first end of the elastic piece 12 and presses the elastic piece 12 during the rotation. After the clamping block 23 is installed in the clamping groove 14, the elastic piece 12 returns to its initial position under its own elastic force, so that the second end is tilted relative to the first end, which helps to form a limiting effect on the clamping block 23.
[0031] In addition, a protruding block 25 protruding toward the second side is provided at the first end of the clamping block 23. The protruding block 25 protrudes in the second side direction to overlap with the elastic piece 12 in the first side to the second side direction to increase the clamping ability.
[0032] The main function of the abutting portion 13 is to form the groove wall of the clamping groove 14 and play a limiting role on the clamping block 23. Preferably, the abutting portion 13 is configured as a frame structure, and a reinforcing plate 17 is provided inside the abutting portion 13. According to actual needs, the reinforcing plate 17 may include plates extending in different directions to achieve a reinforcing effect.
[0033] In addition, a connection hole 26 penetrating in the first side to the second side direction is provided on the clamping block 23. The connection hole 26 is reserved for convenient installation of an anti-theft cover plate. When installing the anti-theft cover plate, the connection hole 26 can be enabled and used as the connection hole for installing the anti-theft cover plate. When the anti-theft cover plate is not installed, the connection hole 26 does not affect the normal operation of the clamping block 23 and the like.
[0034] The present application also relates to a lock core and handle bracket assembly. The lock core and handle bracket assembly includes the above-mentioned handle bracket 1 and lock core 2. During the installation process, the lock core body 21 is first inserted into the installation hole 15 from the first side of the handle bracket body 11. At this time, the wing plate 22 and the clamping block 23 are located on the first side of the handle bracket body 11. Then, the lock core body 21 rotates clockwise with the axial direction of the lock core body 21 as the central axis, driving the wing plate 22 to rotate, and further driving the clamping block 23 to rotate, so that the clamping block 23 is installed into the clamping groove 14. During the rotation of the wing plate 22 driving the clamping block 23, the clamping block 23 first contacts the first end of the elastic piece 12, and presses against the elastic piece 12 during the rotation process, causing the elastic piece 12 to deform in the direction of the second side, which does not affect the installation of the clamping block 23. After the clamping block 23 is installed into the clamping groove 14, the elastic piece 12 returns to its initial position under its own elastic force, so that the second end tilts relative to the first end, which helps to form a limiting effect on the clamping block 23. In addition, after the clamping block 23 is clamped into the clamping groove 14, the handle bracket body 11 and the blocking plate 16 form a limiting effect on the clamping block 23 in the direction from the first side to the second side. During the disassembly or replacement process, the lock core 2 can also be disassembled from the handle bracket 1. For example, hold the second end of the elastic piece 12 so that it no longer limits the clamping block 23, and make the lock core body 21 rotate counterclockwise with the axial direction of the lock core body 21 as the central axis, driving the wing plate 22 to rotate, and then rotating the clamping block 23 onto the elastic piece 12, and driving the clamping block 23 to rotate out of the clamping groove 14. Finally, the lock core 2 is removed from the installation hole 15. It can be seen that in the lock core and handle bracket assembly of the present application, the fastening strength of the lock core 2 is relatively large, the installation process is simple, the anti-destruction ability of the lock core is very strong, and it has the characteristics of simple structure, firm and durable, etc.
[0035] The present application also relates to a vehicle door. The vehicle door includes a door body and the above-mentioned lock core and handle bracket assembly. Among them, the handle bracket 1 is fixedly arranged on the door body. The vehicle door is especially a cab door. According to traffic regulations in different regions, for example, within the Chinese region, the cab door is the front left door. When the cab door is the front left door, after the lock core and handle bracket assembly is installed in place, the first end is consistent with the rear end direction of the vehicle, the second end is consistent with the front end direction of the vehicle, the first side is consistent with the inner side direction of the vehicle, and the second side is consistent with the outer side direction of the vehicle. It should be further noted that the orientation terms "first side", "second side", "first end" and "second end" refer to the directions in the drawings (specifically marked in Figure 3 ), and are only for the convenience of describing the present invention and simplifying the description, so they cannot be understood as limitations on the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.
