Description

Technical Field

[0001] The present invention relates to the technical field of drawer design, and in particular to a vehicle-mounted drawer structure and a vehicle. Background Art

[0002] At present, with the upgrading of cars, people have higher and higher requirements for car drawers. Car drawers not only need to meet the needs of accommodating items, but also need to be equipped with damping parts to improve the drawer pop-up speed to prevent the drawer from popping out too quickly, making too loud noise or hitting passengers.

[0003] In the related art, a traditional vehicle-mounted drawer with a damping structure has a storage cavity inside the vehicle, a pull-out drawer is arranged in the storage cavity, and a damping buffer is arranged between the pull-out drawer and the inner wall of the storage cavity. Through the damping effect of the damping buffer, the pull-out drawer reduces its moving speed when it is pulled out or put into the storage cavity, so that the pull-out drawer moves slower during use and is safer to use.

[0004] However, traditional vehicle-mounted drawers with damping structures still have the following defects: when the vehicle encounters various acceleration and deceleration conditions during driving, the drawers will automatically pop out under the action of inertia, causing the risk of customer complaints. Summary of the Invention

[0005] The present application provides a vehicle-mounted drawer structure and a vehicle, which solves the problem that the drawer automatically pops open under the action of inertia when the vehicle is accelerating or decelerating.

[0006] In a first aspect, an embodiment of the present application provides a vehicle-mounted drawer structure, comprising:

[0012] The labyrinth lock core comprises a core shaft movably arranged in the labyrinth groove. When the core shaft is located in the recess, the inner compartment of the drawer is locked.

[0013] In combination with the first aspect, in one embodiment, the M-shaped groove is surrounded by irregular guide strips, and the irregular guide strips extend further forward along the outlet and the inlet to form a trumpet-shaped opening; a wedge block is provided in the center of the M-shaped groove, and the wedge block has a guide surface facing the outlet.

[0014] In combination with the first aspect, in one embodiment, a reel is rotatably installed on the front end surface of the drawer inner compartment, and a coil spring is arranged on the reel. The protruding end of the coil spring extends along the bottom of the drawer inner compartment and is fixed to the rear part of the drawer chassis; when the drawer inner compartment is closed, the coil spring is in a tensioned state.

[0015] In combination with the first aspect, in one embodiment, the gravity hammer includes a rotating part, a gravity part and a torsion spring for resetting, the rotating part is arranged on the top surface of the drawer bottom plate, the gravity part is connected to the rotating part, the protrusion is located on the top surface of the rotating part, and the torsion spring is arranged inside the rotating part; the gravity part swings forward under the action of inertia, driving the rotating part to rotate, and after rotation, the protrusion presses against the inner bucket of the drawer.

[0017] In combination with the first aspect, in one embodiment, a rack is provided on the bottom surface of the drawer inner compartment along the moving direction, and a gear damper is provided on the top surface of the drawer bottom plate, and the gear damper is engaged with the rack.

[0018] In combination with the first aspect, in one embodiment, the drawer structure further includes a spring sheet, one end of which is fixed to the front end of the drawer bottom plate, and the other end is abutted against the front end of the drawer inner compartment; when the drawer inner compartment is in a closed state, the spring sheet is in a compressed state.

[0019] In combination with the first aspect, in one embodiment, the cross-section of the drawer bottom plate is W-shaped, and a pair of lower slide rails are arranged in the two recesses of the W-shaped structure; the bottom of the drawer inner bucket is V-shaped, and a pair of upper slide rails are arranged on the bottom surfaces on both sides, and the upper slide rails match the lower slide rails.

[0020] In a second aspect, the present application also discloses a car comprising the above-mentioned vehicle-mounted drawer structure.

[0021] The beneficial effects of the technical solutions provided in the embodiments of the present application include at least:

[0022] 1. The drawer structure of the present application is provided with a labyrinth groove and a labyrinth lock core that cooperate with each other between the drawer inner bucket and the drawer bottom plate, so that the drawer inner bucket needs to be opened forward first and then backward when it is normally opened; the drawer inner bucket has a tendency to open backward under the inertia of the vehicle acceleration condition, but the labyrinth lock core hooks the drawer inner bucket through the labyrinth groove, and the drawer inner bucket cannot be pulled out relative to the drawer bottom plate, which can ensure that the drawer inner bucket does not bounce open under the inertia of the vehicle acceleration condition; the drawer structure of the present application is also provided with a heavy Hammer, when the drawer inner compartment is closed, the raised part of the gravity hammer is located on the outside of the drawer inner compartment; when the gravity hammer swings forward under the inertia of the vehicle deceleration condition, the raised part rotates to the front end of the drawer inner compartment, blocking the drawer inner compartment from moving forward, effectively preventing the drawer inner compartment from falling out of the maze lock core from the maze groove under the inertia of the vehicle deceleration condition; the maze groove, maze lock core and gravity hammer can effectively solve the problem that the drawer will automatically pop open under the inertia of the vehicle during acceleration and deceleration conditions. The structural design is ingenious and the user experience is good.

[0023] 2. The drawer structure of the present application is provided with a coil spring. When the inner compartment of the drawer is in a closed state, the coil spring is in a tensioned state, providing a pre-tightening force for the inner compartment of the drawer, so that the inner compartment of the drawer has an unlocking travel space for inward displacement (required for unlocking the maze lock), but the inner compartment of the drawer will not shake relative to the drawer chassis when closed; at the same time, the coil spring can also enable the inner compartment of the drawer to overcome the pre-tightening force of the coil spring when the vehicle is decelerating, so that the forward movement of the inner compartment of the drawer under the action of inertia always occurs after the gravity hammer swings forward, laying the foundation for avoiding the inner compartment of the drawer from bouncing open during deceleration.

[0024] 3. The drawer structure of the present application is provided with a gravity hammer. When the vehicle is stationary or accelerating, the gravity hammer is in an initial state under the action of the torsion spring and will not swing; two fixed blocks are provided at the front end of the drawer inner bucket, one of which is used to abut against the raised part after rotation, and the bottom surface of the fixed block is higher than the top surface of the rotating part and the gravity part, and lower than the raised part; when the drawer inner bucket is opened normally, the fixed block on the front end surface of the drawer inner bucket can pass over the rotating part and the gravity part, and will not block the fixed block at this time; when the vehicle deceleration reaches a set threshold, the gravity hammer swings forward under the action of inertia, the gravity part swings and drives the rotating part to rotate, and after rotation, the raised part abuts against the fixed block, blocking the drawer inner bucket from moving forward, so that the core shaft cannot escape from the maze groove; more importantly, the moment when the drawer inner bucket overcomes the pre-tightening force of the coil spring and moves forward under the action of inertia is later than the moment when the gravity hammer swings into place, that is, the gravity hammer can block the drawer inner bucket in time during deceleration to prevent the drawer inner bucket from automatically bouncing open under deceleration conditions. The structural design is ingenious. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] In order to enable those skilled in the art to better understand the present invention, 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. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0040] The present application provides a vehicle-mounted drawer structure and a vehicle, which solves the problem that the drawer automatically pops open under the action of inertia when the vehicle is accelerating or decelerating.

[0041] like Figures 1 to 12 As shown, the present application discloses an embodiment of a vehicle-mounted drawer structure, which includes a drawer chassis 3, a drawer inner compartment 1 and a gravity hammer 33.

[0042] The drawer chassis 3 is provided with a labyrinth lock cylinder 34. The drawer interior 1 is provided with a labyrinth groove 14 that cooperates with the labyrinth lock cylinder 34. The drawer interior 1 is slidably mounted on the drawer chassis 3 via the labyrinth groove 14 and the labyrinth lock cylinder 34. Specifically, the labyrinth lock cylinder 34 is rotatably mounted on the top surface of the drawer chassis 3, and the labyrinth groove 14 is provided on the bottom surface of the drawer interior 1.

[0043] The gravity hammer 33 is rotatably disposed on the drawer bottom plate 3 , and the gravity hammer 33 has a protrusion 334 .

[0044] When the drawer inner compartment 1 is closed, the protrusion 334 is located outside the drawer inner compartment 1 (see Figure 8 When the gravity hammer 33 swings forward under the inertia of the vehicle deceleration condition, the protrusion 334 rotates to the front end of the drawer inner bucket 1 (see Figure 9 ), preventing the drawer inner bucket 1 from moving forward.

[0045] Specifically, when the vehicle is stationary or accelerating, the gravity hammer 33 is always in the state of Figure 8 After the gravity hammer 33 swings forward under the inertia of the vehicle deceleration condition, it is in the state as shown Figure 9 The state after swinging is shown.

[0046] The drawer structure of the present application is provided with a labyrinth groove 14 and a labyrinth lock core 34 that cooperate with each other between the drawer inner bucket 1 and the drawer bottom plate 3, so that the drawer inner bucket 1 needs to be opened forward and then backward when it is normally opened; the drawer inner bucket 1 has a tendency to open backward under the inertia of the vehicle acceleration working condition, but the labyrinth lock core 34 hooks the drawer inner bucket 1 through the labyrinth groove 14, and the drawer inner bucket 1 cannot be pulled outward relative to the drawer bottom plate 3, which can ensure that the drawer inner bucket 1 does not bounce open under the inertia of the vehicle acceleration working condition; the drawer structure of the present application is also provided with a gravity hammer 33, and the drawer When the inner bucket 1 is closed, the protrusion 334 of the gravity hammer 33 is located on the outside of the drawer inner bucket 1; when the gravity hammer 33 swings forward under the inertia of the vehicle deceleration condition, the protrusion 334 rotates to the front end of the drawer inner bucket 1, blocking the drawer inner bucket 1 from moving forward, and effectively preventing the drawer inner bucket 1 from escaping from the maze lock core 34 from the maze groove 14 under the inertia of the vehicle deceleration condition; the maze groove 14, the maze lock core 34 and the gravity hammer 33 can effectively solve the problem that the drawer will automatically pop open under the inertia of the vehicle during acceleration and deceleration conditions. The structural design is ingenious and the user experience is good.

[0047] like Figure 10 and Figure 11 As shown, in one embodiment, the labyrinth groove 14 is a transverse M-shaped groove, with an outlet 144 and an inlet 145 respectively provided at both ends of the M-shaped groove, with the outlet 144 and the inlet 145 facing the gravity hammer 33. A stopper 143 with a recess corresponding to the middle tip of the M shape is provided between the outlet 144 and the inlet 145 in the M-shaped groove.

[0048] The labyrinth lock cylinder 34 includes a spindle 341 that is movably disposed within the labyrinth groove 14. The spindle 341 at the rear end of the labyrinth lock cylinder 34 is inserted upward into the labyrinth groove 14. When the drawer compartment 1 is closed or opened relative to the drawer chassis 3, the spindle 341 moves in and out through the outlet 144 and the inlet 145. When the spindle 341 is located within the recess of the stopper 143, the drawer compartment 1 is locked.

[0049] When the drawer inner compartment 1 is closed, the core shaft 341 is inserted into the depression of the block 143 of the labyrinth groove 14 (i.e., the middle tip of the M shape), and the core shaft 341 hooks the drawer inner compartment 1 through the labyrinth groove 14. The drawer inner compartment 1 cannot be pulled outward relative to the drawer chassis 3, which can ensure that the drawer inner compartment 1 does not bounce open under the inertia of the vehicle acceleration condition.

[0050] Furthermore, the bottom surface of the drawer inner compartment 1 is provided with an irregular guide strip 141, a stopper 143, and a wedge block 142 protruding downward. The M-shaped groove is surrounded by the irregular guide strip 141, and the irregular guide strip 141 further extends forward along the outlet 144 and the inlet 145 to form a trumpet-shaped opening for guiding the core shaft 341.

[0051] A wedge-shaped block 142 is located in the center of the M-shaped groove, spaced from a stopper 143. Wedge-shaped block 142 has a guide surface facing an outlet 144. Wedge-shaped block 142 is spaced relative to stopper 143, and stopper 143 and wedge-shaped block 142 sandwich the middle tip of the M-shape. When the mandrel 341 is located within the recess of stopper 143 and the drawer compartment 1 moves inward relative to the drawer chassis 3, the mandrel 341 follows the guide surface and enters the outlet 144, allowing the drawer compartment 1 to be withdrawn normally.

[0052] Specifically, when the drawer compartment 1 is fully opened, it remains within the trumpet-shaped opening of the irregular guide strip 141. When the drawer compartment 1 is closed, the spindle 341 is inserted into the middle tip of the M-shaped labyrinth groove 14, that is, the spindle 341 hooks onto the stopper 143, preventing the drawer compartment 1 from being directly withdrawn from the drawer chassis 3. To open the drawer compartment 1 normally, the drawer compartment 1 first moves inward a certain distance to unlock, allowing the spindle 341 to slide along the wedge 142 into the channel corresponding to the outlet 144. The drawer compartment 1 is then withdrawn, allowing it to open normally.

[0053] When the drawer inner compartment 1 is moved from the open state to the closed state, the core shaft 341 approaches the stopper 143 along the irregular guide strip 141, then enters the inlet 145 along the guide slope of the stopper 143, and then enters the middle tip of the M-shaped labyrinth groove 14. Figure 11 As shown, after the core shaft 341 enters the innermost part of the entrance 145, it can only reach the middle tip of the M-shaped labyrinth groove 14, and then open the drawer inner compartment 1 forward and then backward.

[0054] The labyrinth lock of the present application can effectively prevent the inner bucket 1 of the drawer from automatically popping open due to inertia when the vehicle is accelerating.

[0055] In one embodiment, the drawer structure further includes a drum 15, which is rotatably mounted on the front end of the drawer compartment 1, with the axis of the drum 15 arranged in the left-right direction. A coil spring 12 is wound around the drum 15, and the extended end of the coil spring 12 extends along the bottom of the drawer compartment 1 and is fixed to the rear of the drawer chassis 3.

[0056] The labyrinth groove 14 and the labyrinth lock core 34 form a labyrinth lock. When the drawer inner compartment 1 is closed, the labyrinth lock is in a locked state and the coil spring 12 is in a tensioned state.

[0057] When the drawer compartment 1 is closed, the coil spring 12 is in a tensioned state, providing a preload force to the drawer compartment 1. The drawer compartment 1 always tends to move backward, but the labyrinth lock core 34 fits tightly into the labyrinth groove 14, preventing the drawer compartment 1 from opening backward directly. To open the drawer compartment 1, it must first move forward, overcoming the preload force provided by the coil spring 12.

[0058] The drawer structure of the present application is provided with a coil spring 12. When the drawer inner compartment 1 is in a closed state, the coil spring 12 is in a tensioned state, providing a pre-tightening force for the drawer inner compartment 1, so that even if the drawer inner compartment 1 has an unlocking travel space for inward displacement (necessary to unlock the maze lock), the drawer inner compartment 1 will not shake relative to the drawer chassis 3 when closed; at the same time, the coil spring 12 can also enable the drawer inner compartment 1 to overcome the pre-tightening force of the coil spring 12 when the vehicle is decelerating, so that the forward movement of the drawer inner compartment 1 under the action of inertia always occurs after the gravity hammer 33 swings forward, laying the foundation for preventing the drawer inner compartment 1 from bouncing open during deceleration.

[0059] Preferably, the drawer structure further comprises a rectangular drawer frame 2 , which is fixedly arranged at the rear of the drawer chassis 3 , and the drawer inner compartment 1 passes through the drawer frame 2 .

[0060] In one embodiment, the gravity hammer 33 further includes a rotating portion 331, a gravity portion 332, a protrusion 334, and a torsion spring 335 for resetting. The rotating portion 331 is rotatably mounted on the top surface of the drawer chassis 3, while the gravity portion 332 is suspended from the rotating portion 331. The protrusion 334 is mounted on the top surface of the rotating portion 331, and the torsion spring 335 is disposed within the rotating portion 331. The torsion spring 335 is used to restrict the gravity portion 332 from swinging only away from the drawer compartment and facilitates the reset of the gravity hammer 333 after swinging. Specifically, when the vehicle is stationary or accelerating, the gravity hammer 333 is in its initial state under the action of the torsion spring 335 and does not swing.

[0061] When the vehicle deceleration reaches a set threshold, the gravity hammer 33 swings forward under the action of inertia, the gravity part 332 swings and drives the rotating part 331 to rotate. After rotation, the protrusion 334 presses against the drawer inner bucket 1, blocking the drawer inner bucket 1 from moving forward, so that the core shaft 341 cannot escape from the labyrinth groove 14.

[0062] The gravity hammer 33 swings forward by 90 degrees under the action of inertia. The state in which the gravity hammer 33 swings forward by 90 degrees is as follows: Figure 9 As shown, the drawer compartment 1 moves forward under inertia, overcoming the preload of the coil spring 12, after the gravity hammer 33 swings into position. Specifically, after the gravity hammer 33 swings into position (i.e., 90°), the drawer compartment 1 moves forward under inertia, overcoming the preload of the coil spring 12. At this point, the fixed block 16 of the drawer compartment 1 is held against the protrusion 334. The gravity hammer 33 and the labyrinth lock work together to prevent the drawer compartment 1 from opening during both acceleration and deceleration.

[0063] Specifically, the gravity hammer 33 further includes a connecting portion 333 , which connects the rotating portion 331 and the gravity portion 332 . Specifically, the gravity hammer 33 is located at the front of the drawer chassis 3 , and the labyrinth lock is located at the rear of the drawer chassis 3 .

[0064] The drawer structure of the present application is provided with a gravity hammer 33. When the vehicle is stationary or accelerating, the gravity hammer 33 is in an initial state under the action of the torsion spring 335 and will not swing; when the vehicle deceleration reaches a set threshold, the gravity hammer 33 swings forward under the action of inertia, the gravity part 332 swings and drives the rotating part 331 to rotate, and after rotation, the protrusion 334 stops the drawer inner bucket 1 from moving forward, so that the core shaft 341 cannot escape from the maze groove 14; more importantly, the moment when the drawer inner bucket 1 overcomes the pre-tightening force of the coil spring 12 and moves forward under the action of inertia is later than the moment when the gravity hammer 33 swings into place, that is, when decelerating, the gravity hammer 33 can stop the drawer inner bucket 1 in time to prevent the drawer inner bucket 1 from automatically popping open under the deceleration condition. The structural design is ingenious.

[0065] In one embodiment, two fixing blocks 16 are provided at the front end of the drawer inner compartment 1 , and the reel 15 is rotatably installed between the two fixing blocks 16 , wherein one of the fixing blocks 16 is used to abut against the raised portion 334 after rotation.

[0066] Specifically, the bottom surface of the fixed block 16 is higher than the top surfaces of the rotating part 331 and the gravity part 332, and is also higher than the top surface of the connecting part 333, and is lower than the protrusion 334. That is, when the drawer inner bucket 1 is opened normally and the drawer inner bucket 1 needs to move inward, the fixed block 16 at the front end surface of the drawer inner bucket 1 passes over the rotating part 331 and the gravity part 332, and will not block the fixed block 16 at this time.

[0067] In one embodiment, a rack 13 is provided on the bottom surface of the drawer compartment 1 along the direction of movement, and a gear damper 35 is provided on the upper surface of the drawer chassis 3. The gear damper 35 engages with the rack 13. The gear damper 35 and the rack 13 cooperate to prevent the drawer compartment 1 from opening too quickly after being unlocked, or even striking an occupant.

[0068] In one embodiment, the drawer structure further includes a spring 32, one end of which is fixed to the front top surface of the drawer bottom plate 3, and the other end of which is inclined against the front end surface of the drawer inner compartment 1. When the drawer inner compartment 1 is in the closed state, the spring 32 is in a compressed state.

[0069] There is usually lubricating oil when the gear damper 35 is engaged with the rack 13, but the lubricating oil will freeze in extremely cold and humid weather, which will cause an obstacle to the opening of the drawer. In the drawer structure of the present application, the function of the shrapnel 32 is that after the maze lock of the drawer inner compartment 1 is unlocked, the shrapnel 32 can pop outward, making it easier to open the drawer inner compartment 1 in extremely cold and humid weather.

[0070] In one embodiment, the drawer chassis 3 has a W-shaped cross section, with a pair of lower rails 31 disposed within the two recesses of the W-shaped structure. The bottom of the drawer compartment 1 is V-shaped, with a pair of upper rails 11 disposed on the bottom surfaces on both sides, which mate with the lower rails 31.

[0071] In the drawer structure of the present application, the cross-section of the drawer bottom plate 3 is W-shaped, and the bottom of the drawer inner bucket 1 is V-shaped. The two are tightly connected to each other, so that the connection stability of the drawer inner bucket 1 is good, which can meet the abuse force requirements in the up and down directions, and more importantly, can meet the abuse force requirements in the left and right directions.

[0072] A car comprises the above-mentioned vehicle-mounted drawer structure.

[0073] About cars, such as Figure 10 and Figure 11 As shown, in one embodiment, the labyrinth groove 14 is a transverse M-shaped groove, with an outlet 144 and an inlet 145 respectively provided at both ends of the M-shaped groove, and the outlet 144 and the inlet 145 are oriented in the direction of the gravity hammer 33. A stopper 143 with a depression corresponding to the middle tip of the M shape is provided between the outlet 144 and the inlet 145 in the M-shaped groove. The labyrinth lock core 34 includes a core shaft 341 movably provided in the labyrinth groove 14, and the core shaft 341 at the rear end of the labyrinth lock core 34 is inserted upward into the labyrinth groove 14. When the drawer inner compartment 1 is closed or opened relative to the drawer bottom plate 3, the core shaft 341 moves in and out from the outlet 144 and the inlet 145; when the core shaft 341 is located in the depression of the stopper 143, the drawer inner compartment 1 is locked. When the drawer inner compartment 1 is closed, the core shaft 341 is inserted into the depression of the block 143 of the labyrinth groove 14 (i.e., the middle tip of the M shape), and the core shaft 341 hooks the drawer inner compartment 1 through the labyrinth groove 14. The drawer inner compartment 1 cannot be pulled outward relative to the drawer chassis 3, which can ensure that the drawer inner compartment 1 does not bounce open under the inertia of the vehicle acceleration condition.

[0074] Furthermore, the bottom surface of the drawer inner bucket 1 is provided with an irregular guide strip 141, a stopper 143 and a wedge block 142 protruding downward. The M-shaped groove is surrounded by the irregular guide strip 141, and the irregular guide strip 141 further extends forward along the outlet 144 and the inlet 145 to form a trumpet-shaped opening for guiding the core shaft 341. A wedge block 142 is provided in the center of the M-shaped groove relative to the stopper 143, and the wedge block 142 has a guide surface facing the outlet 144. The wedge block 142 is relatively spaced apart from the triangular stopper 143, and the stopper 143 and the wedge block 142 are clamped together to form the middle tip of the M shape. When the core shaft 341 is located in the recess of the stopper 143 and the drawer inner bucket 1 moves inward relative to the drawer bottom plate 3, the core shaft 341 enters the outlet 144 along the guide surface, and then the drawer inner bucket 1 can be pulled out normally.

[0075] Specifically, when the drawer compartment 1 is fully opened, it remains within the trumpet-shaped opening of the irregular guide strip 141. When the drawer compartment 1 is closed, the spindle 341 is inserted into the middle tip of the M-shaped labyrinth groove 14, that is, the spindle 341 hooks onto the triangular stopper 143, preventing the drawer compartment 1 from being directly withdrawn from the drawer chassis 3. To open the drawer compartment 1 normally, the drawer compartment 1 first moves inward a certain distance to unlock, allowing the spindle 341 to slide along the wedge 142 into the channel corresponding to the exit 144. The drawer compartment 1 is then withdrawn, allowing it to open normally.

[0076] When the drawer inner compartment 1 is moved from the open state to the closed state, the core shaft 341 approaches the stopper 143 along the irregular guide strip 141, then enters the entrance 145 along the guide slope of the triangular stopper 143, and then enters the middle tip of the M-shaped labyrinth groove 14. Figure 11 As shown, after the core shaft 341 enters the innermost part of the entrance 145, it can only reach the middle tip of the M-shaped labyrinth groove 14, and then open the drawer inner compartment 1 forward and then backward.

[0077] The automobile of the present application can effectively prevent the inner bucket 1 of the drawer from automatically popping open due to inertia when the vehicle is accelerating.

[0078] Regarding automobiles, in one embodiment, the drawer structure further includes a drum 15, which is rotatably mounted on the front end of the drawer compartment 1, with the axis of the drum 15 arranged in the left-right direction. A coil spring 12 is wound around the drum 15, the extended end of which extends along the bottom of the drawer compartment 1 and is fixed to the rear of the drawer chassis 3. A labyrinth groove 14 and a labyrinth lock core 34 form a labyrinth lock. When the drawer compartment 1 is closed, the labyrinth lock is locked, and the coil spring 12 is tensioned. When the drawer compartment 1 is closed, the coil spring 12 is tensioned, providing a preload for the drawer compartment 1. The drawer compartment 1 always tends to move backward, but the labyrinth lock core 34 fits tightly with the labyrinth groove 14, preventing the drawer compartment 1 from opening directly backward. To open, the drawer compartment 1 must first move forward, which means the drawer compartment 1 must overcome the preload provided by the coil spring 12.

[0079] In the automobile of the present application, a coil spring 12 is provided in the drawer structure. When the drawer inner compartment 1 is in a closed state, the coil spring 12 is in a tensioned state, providing a pre-tightening force for the drawer inner compartment 1, so that even if the drawer inner compartment 1 has an unlocking travel space for inward displacement (necessary to unlock the maze lock), the drawer inner compartment 1 will not shake relative to the drawer chassis 3 when closed; at the same time, the coil spring 12 can also enable the drawer inner compartment 1 to overcome the pre-tightening force of the coil spring 12 when the vehicle is decelerating, so that the forward movement of the drawer inner compartment 1 under the action of inertia always occurs after the gravity hammer 33 swings forward, laying the foundation for preventing the drawer inner compartment 1 from bouncing open during deceleration.

[0080] Furthermore, the gravity hammer 33 also includes a rotating portion 331, a gravity portion 332, a raised portion 334, and a torsion spring 335 for resetting. The rotating portion 331 is rotatably mounted on the top surface of the drawer chassis 3, while the gravity portion 332 is suspended from the rotating portion 331. The raised portion 334 is mounted on the top surface of the rotating portion 331, and the torsion spring 335 is disposed within the rotating portion 331. The torsion spring 335 is used to restrict the gravity portion 332 from swinging only away from the drawer compartment and to facilitate the reset of the gravity hammer 333 after swinging. Specifically, when the vehicle is stationary or accelerating, the gravity hammer 333 is in its initial state under the action of the torsion spring 335 and does not swing.

[0081] When the vehicle deceleration reaches a set threshold, the gravity hammer 33 swings forward under the action of inertia, the gravity portion 332 swings and drives the rotating portion 331 to rotate. After the rotation, the protrusion 334 abuts against the drawer inner bucket 1, blocking the drawer inner bucket 1 from moving forward, so that the core shaft 341 cannot escape from the labyrinth groove 14. The gravity hammer 33 swings forward under the action of inertia and will swing 90 degrees. The state of the gravity hammer 33 swinging forward 90 degrees is shown as follows: Figure 9 As shown. The moment when the drawer inner bucket 1 overcomes the preload force of the coil spring 12 and moves forward under the action of inertia is later than the moment when the gravity hammer 33 swings into position, that is, after the gravity hammer 33 swings into position (i.e., swings 90°), the drawer inner bucket 1 overcomes the preload force of the coil spring 12 and moves forward under the action of inertia. At this time, the fixed block 16 of the drawer inner bucket 1 is supported by the protrusion 334. The gravity hammer 33 and the labyrinth lock cooperate to prevent the drawer inner bucket 1 from bouncing open during acceleration and deceleration. Specifically, the gravity hammer 33 also includes a connecting portion 333, which connects the rotating portion 331 and the gravity portion 332. Specifically, the gravity hammer 33 is located at the front of the drawer chassis 3, and the labyrinth lock is located at the rear of the drawer chassis 3.

[0082] The bicycle of the present application is provided with a gravity hammer 33. The gravity hammer 33 is in an initial state under the action of the torsion spring 335 when the vehicle is stationary or accelerating, and will not swing; when the deceleration of the vehicle reaches a set threshold, the gravity hammer 33 swings forward under the action of inertia, the gravity part 332 swings and drives the rotating part 331 to rotate, and after rotation, the protrusion 334 stops the drawer inner bucket 1 from moving forward, so that the core shaft 341 cannot escape from the maze groove 14; more importantly, the moment when the drawer inner bucket 1 overcomes the pre-tightening force of the coil spring 12 and moves forward under the action of inertia is later than the moment when the gravity hammer 33 swings into place, that is, when decelerating, the gravity hammer 33 can stop the drawer inner bucket 1 in time to prevent the drawer inner bucket 1 from automatically popping open under the deceleration condition. The structural design is ingenious.
