[0011] Figure 2 is the left view of the present utility model. Detailed Embodiment

[0012] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0013] Please refer to Figure 1-2 , the present utility model provides the following technical solutions: A locking mechanism for a glove box of a commercial truck, including a motor 1, a latch rod 2, a latch 3, a traction lock cantilever 4, and a manual switch 5. There are two latches 3. When the glove box is closed, the ends on both sides of the traction lock cantilever 4 are located inside the latches 3. One end of the latch rod 2 vertically passes through a latch 3 and then inserts into the end of the traction lock cantilever 4. The other end of the latch rod 2 is connected to the motor 1. In this state, if the manual switch 5 is toggled, the strain displacement of the traction lock cantilever 4 is restricted by the latch rod 2, and the glove box still cannot be opened. The main body of the traction lock cantilever 4 is a central symmetry structure. The manual switch 5 is installed on the traction lock cantilever 4 on the side close to the motor 1. When the glove box needs to be opened, the driver first needs to control through a button, and the motor 1 will normally drag the latch rod 2 to disengage from the end of the traction lock cantilever 4 and from the latch 3. The traction lock cantilever 4 is no longer limited. By toggling the manual switch 5, the traction lock cantilever 4 will generate a strain displacement. The end of the traction lock cantilever 4 on the side of the motor 2 leaves the latch 3, and the center of the traction lock cantilever 4 generates a clockwise rotational movement, guiding the end on the other side of the traction lock cantilever 4 to also leave the latch 3. Therefore, the glove box can freely rotate in the normal direction of the outer cover plate, and the glove box can be opened by an external force. The settings of the latch rod 2 and the motor 1 realize the locking function of the glove box, enhancing the safety of in-vehicle storage. The present utility model has fewer parts, low manufacturing cost, small space occupied by the locking mechanism, good durability, and strong practicability.

[0014] Specifically, a through hole 401 is provided in the middle of the towing lock cantilever 4. A nylon rivet is installed in the through hole 401, and the towing lock cantilever 4 is installed on the upper side of the inner surface of the glove box outer cover through the nylon rivet.

[0015] Specifically, a clamping groove 301 is provided in the middle of the latch 3. The two ends of the towing lock cantilever 4 are located in the clamping groove 301, so that the glove box is closed. A groove 402 is provided at one end of the towing lock cantilever 4. One end of the bolt 2 is inserted into the groove 402 to limit the towing lock cantilever 4, preventing the glove box from being opened manually by the manual switch 5, and protecting the driver's privacy and safety by preventing the glove box from being opened without the driver's permission or accidentally touched.

[0016] Specifically, the two latches 3 are fixed on the instrument panel skeleton. When the two ends of the towing lock cantilever 4 are clamped into the clamping groove 301, the glove box is closed. The manual switch 5 passes through the glove box outer cover and is exposed on the surface of the glove box outer cover, and the manual switch 5 is located on the side close to the driver, which is convenient for the driver to open the glove box during driving and improves driving safety.

[0017] Specifically, the towing lock cantilever 4 is made of PA612 material, which has the advantages of small relative width, low water absorption rate, low density, good dimensional stability, high tensile strength and impact strength, and stable structure.

[0018] The movement process of the present utility model is as follows: When the glove box needs to be opened, the driver first needs to control through the button, and the motor 1 will normally drag the bolt 2 out of the groove 402 of the towing lock cantilever 4 and out of the clamping groove 301 of the latch 3. The towing lock cantilever 4 is no longer limited. The manual switch 5 is toggled, and the towing lock cantilever 4 will generate a strain displacement. The end of the towing lock cantilever 4 on the side of the motor 2 leaves the latch 3. Since the main body of the towing lock cantilever 4 is a centrally symmetric structure, a clockwise rotational movement is generated at the center of the towing lock cantilever 4, and the other end of the towing lock cantilever 4 is guided to also leave the latch 3. Therefore, the glove box can rotate freely in the normal direction of the outer cover surface, and the glove box can be opened by an external force. When the glove box needs to be closed, first push the glove box into the instrument panel skeleton to the innermost, then pull the manual switch 5, a counterclockwise movement is generated at the center of the towing lock cantilever 4, pushing the two ends of the towing lock cantilever 4 to insert into the clamping groove 301 of the latch 3. The driver then controls through the button, and the motor 1 will normally insert the bolt 2 into the groove 402 of the towing lock cantilever 4, the glove box is closed, and the glove box is locked.

[0019] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements on some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
