[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0032] The present invention provides Figures 1-6The novel mechanical locking mechanism for a car glove box shown in the figure includes a first locking rod 1, a second locking rod 2, and a locking rod connector 3 connecting the first locking rod 1 and the second locking rod 2. The first locking rod 1 and the second locking rod 2 are both provided with elastic return members for driving them to rebound. The first locking rod 1 and the second locking rod 2 have the same length and overall structure, and are symmetrically distributed.

[0033] It also includes a switch mechanism 4 that drives the first locking rod 1 and the second locking rod 2 to move relative to each other. The switch mechanism 4 includes a switch housing 41 with one side concave to form a groove cavity. A rotatable switch 42 is installed in the groove cavity, and an opening mechanism 43 that pushes the second locking rod 2 to move is clamped on one side of the switch 42. A rebound member that drives the switch 42 to rebound and reset is also provided on the side of the switch housing 41 relative to the groove cavity, and a screw 44 is screwed on the switch housing 41 to fix it to the inner cover of the car glove box.

[0034] Through the above, when in use, first fix the first locking rod 1 and the second locking rod 2 to the outer cover of the car glove box by screws, and then fix the switch housing 41 to the inner cover of the car glove box by screws 44. Then, when the car glove box needs to be opened, the switch 42 can be manually pulled to rotate the switch 42, and then the switch 42 pushes the second locking rod 2 toward the first locking rod 1 through the opening mechanism 43, and the switch 42 presses and deforms the resilient member. At this time, under the action of the lock rod connecting member 3, the first locking rod 1 moves toward the second locking rod 2 to realize the relative movement of the first locking rod 1 and the second locking rod 2, and stretches the elastic reset member so that the lock tongues at one end of the first locking rod 1 and the second locking rod 2 are moved out of the lock groove on the inner wall of the car glove box, thereby realizing the unlocking of the car glove box and facilitating the opening of the car glove box cover (composed of an inner cover and an outer cover, and the inner cover and the outer cover are assembled by welding);

[0035] When the glove box cover is closed and needs to be locked, the switch 42 is released. At this time, the elastic reset member pushes the first locking rod 1 and the second locking rod 2 to move away from each other under the action of the lock rod connecting member 3 to achieve reset, so that the lock tongues at one end of the first locking rod 1 and the second locking rod 2 are inserted into the lock groove on the inner wall of the glove box to achieve the locking and fixing of the glove box cover. At the same time, the resilient member pushes the switch 42 to rotate and reset, and also pre-tightens the switch 42 to prevent the switch 42 from making abnormal noise when it is in place, thereby facilitating the subsequent use of the switch 42.

[0036] In summary, the present invention utilizes the switch mechanism 4 to drive the relative movement of the first locking rod 1 and the second locking rod 2, which not only improves the locking accuracy of the car glove box, but also can realize the rapid unlocking / locking of the car glove box, greatly improving the synchronization of unlocking / locking, and improving the end customer experience.

[0037] Regarding the above elastic reset member, Figure 1-Figure 3 As shown, the elastic return member includes a concave cavity formed on one side of the first locking rod 1 and the second locking rod 2, a hook 6 is fixed on the adjacent side of the two concave cavities, and a rubber band 5 is hung on the two hooks 6, and the ends of the two rubber bands 5 away from the hooks 6 are connected to the car glove box, and a through groove 7 is formed on the first locking rod 1 and the second locking rod 2.

[0038] Specifically, when the glove box cover of the car is opened, the switch 42 is turned to cause the first lock rod 1 and the second lock rod 2 to move relative to each other. At this time, the first lock rod 1 and the second lock rod 2 stretch the rubber band 5, so that the rubber band 5 is stretched from the pre-tightened state to the tensioned state. When the user releases the switch 42, the rubber band 5 returns from the tensioned state to the pre-tightened state. In this process, the tension of the rubber band 5 provides a power source for the first lock rod 1 and the second lock rod 2 to return to their original state.

[0039] Secondly, the connection portion of the car glove box for the rubber band 5 is always in the through groove 7 to ensure the relative movement of the first locking rod 1 and the second locking rod 2 and prevent interference with the movement between the first locking rod 1 and the second locking rod 2.

[0040] Regarding the above-mentioned locking rod connecting member 3, as Figure 1-Figure 3 as well as Figure 6 As shown, the locking rod connector 3 includes a connecting disk 31, an axial hole is opened in the middle of the connecting disk 31, and the connecting disk 31 is installed on the axial rod on the inner wall of the car glove box through the axial hole, and two symmetrically distributed connecting columns 32 are installed on one side of the connecting disk 31, and the middle parts of the two connecting columns 32 are provided with openings, and the sides adjacent to the first locking rod 1 and the second locking rod 2 are provided with through holes for the connecting columns 32 to pass through, and limiting protrusions 33 are formed on both sides of one end of the two connecting columns 32, and the limiting protrusions 33 block and limit the ends of the first locking rod 1 and the second locking rod 2.

[0041] Specifically, when the switch 42 is turned to push the second lock rod 2 to move, one end of the second lock rod 2 pushes the connecting plate 31 through the connecting column 32, causing the connecting plate 31 to rotate around the shaft on the car glove box and pull the first lock rod 1 toward the second lock rod 2 through the connecting column 32, thereby achieving the first lock rod 1 and the second lock rod 2 moving toward each other. When the user releases the switch 42, the elastic reset member drives the first lock rod 1 and the second lock rod 2 to move away from each other, achieving the reset of the first lock rod 1 and the second lock rod 2.

[0042] Secondly, during the relative movement of the first locking rod 1 and the second locking rod 2 through the connecting plate 31, the limiting protrusion 33 can be used to limit and fix the connecting column 32 and the end portions of the first locking rod 1 and the second locking rod 2 to prevent the ends of the first locking rod 1 and the second locking rod 2 from slipping off the connecting column 32, thereby ensuring the stable movement of the first locking rod 1 and the second locking rod 2 and facilitating the unlocking or locking of the car glove box.

[0043] Regarding the above-mentioned rebound member, Figure 3 and Figure 5 As shown, the resilient member includes a spring piece 45 mounted on the side wall of the switch housing 41 , and one end of the spring piece 45 contacts the switch 42 .

[0044] Specifically, when the switch 42 is turned on, the user turns the switch 42. At this time, one end of the switch 42 presses against the spring piece 45 to compress and deform the spring piece 45. When the switch 42 is turned off, the user releases the switch 42. At this time, the spring piece 45 loses the external force and returns to its original state, and pushes the switch 42 to rotate to achieve the reset of the switch 42, thereby facilitating the opening and closing of the car glove box.

[0045] Furthermore, regarding how to rotate the switch 42, as shown in FIG. Figure 3 As shown, a rotating frame 48 is installed on the inner wall of the slot cavity, and a metal rotating shaft 46 is installed on the rotating frame 48 , and both ends of the metal rotating shaft 46 are connected to the switch 42 .

[0046] When the switch 42 is rotated to open or reset, the switch 42 rotates around the rotating frame 48 via the metal rotating shaft 46, thereby realizing the rotation opening and closing of the switch 42, thereby facilitating the opening and closing of the car glove box.

[0047] At the same time, in this embodiment, Figure 3 As shown, a convex beam is formed in the middle of the groove cavity, a mounting hole 49 is opened on the convex beam, and a buffer nail 47 is inserted into the mounting hole 49.

[0048] When the switch 42 is rotated and reset by the spring sheet 45, the buffer nail 47 provided in the mounting hole 49 can buffer and support the switch 42 to ensure that the switch 42 is in a horizontal state after being reset, thereby facilitating the subsequent rotation and opening of the switch 42.

[0049] In addition, in one embodiment, in order to ensure that the first locking rod 1 and the second locking rod 2 can move normally, as shown in FIG. Figure 1-Figure 3 As shown, notches 8 are further provided on the first locking rod 1 and the second locking rod 2 .

[0050] During the movement of the first locking rod 1 and the second locking rod 2, the design of the notch 8 can be used to realize the deformation of the first locking rod 1 and the second locking rod 2 in the Z direction at this position, ensuring that the first locking rod 1 and the second locking rod 2 can rotate around the locking rod connecting piece 3, while ensuring that the second locking rod 2 can achieve horizontal movement at one end close to the lock tongue position, thereby achieving the purpose of simultaneously satisfying the shaft transmission and the horizontal movement of the first locking rod 1 and the second locking rod 2, so as to solve the problem that the first locking rod 1 and the second locking rod 2 cannot move horizontally due to the shaft transmission.

[0051] In summary, see Figure 7As shown, the movement of the first locking rod 1 and the second locking rod 2 in this embodiment is described as follows:

[0052] At positions a-b and a1-b1, the first locking rod 1 and the second locking rod 2 move horizontally;

[0053] At positions b to c and from b1 to c1 , the first locking rod 1 and the second locking rod 2 achieve Z-direction deformation through the elastic deformation of the notch 8 , so as to ensure that the first locking rod 1 and the second locking rod 2 can rotate around the locking rod connector 3 .

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
