Technical Field

[0001] The 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 automobiles, 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 opened 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 can reduce the 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, the traditional vehicle-mounted drawer with a damping structure still has the following defects: when the vehicle encounters various acceleration and deceleration conditions during driving, the drawer will automatically pop out due to inertia, causing the risk of customer complaints.

[0021] The beneficial effects brought by the technical solution provided by the embodiment 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 outward 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 to stop the drawer inner compartment from moving forward, effectively preventing the drawer inner compartment from falling out of 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 under 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 (necessary to unlock 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 preventing 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, which is in an initial state under the action of a torsion spring when the vehicle is stationary or accelerating 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 portion after rotation, and the bottom surface of the fixed block is higher than the top surface of the rotating portion and the gravity portion, and lower than the raised portion; 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 portion and the gravity portion, and the fixed block will not be blocked at this time; when the vehicle deceleration reaches a set threshold, the gravity hammer swings forward under the action of inertia, the gravity portion swings and drives the rotating portion to rotate, and after the rotation, the raised portion abuts against the fixed block, blocking the drawer inner bucket from moving forward, so that the core shaft cannot leave the maze groove; more importantly, the moment when the drawer inner bucket overcomes the preload force of the coil spring under the action of inertia and moves forward is later than the moment when the gravity hammer swings into place, that is, the gravity hammer can stop the drawer inner bucket in time during deceleration to prevent the drawer inner bucket from automatically popping open under deceleration conditions, and the structural design is ingenious.

DETAILED DESCRIPTION

[0039] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, 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 will automatically pop open due to 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, wherein the drawer structure comprises 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 core 34. The drawer inner bucket 1 is provided with a labyrinth groove 14 that cooperates with the labyrinth lock core 34, and the drawer inner bucket 1 is slidably arranged on the drawer chassis 3 through the labyrinth groove 14 and the labyrinth lock core 34. Specifically, the labyrinth lock core 34 is rotatably arranged on the top surface of the drawer chassis 3, and the labyrinth groove 14 is arranged on the bottom surface of the drawer inner bucket 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 compartment 1 is closed, the protrusion 334 is located outside the drawer 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 Fig. 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 a state of Figure 8 After the gravity hammer 33 swings forward under the inertia of the vehicle deceleration condition, it is in the following state Fig. 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 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 condition; the drawer structure of the present application is also provided with a gravity hammer 33, and the drawer inner bucket 1 is locked. 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 labyrinth groove 14 under the inertia of the vehicle deceleration condition; the labyrinth groove 14, the labyrinth 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 under acceleration and deceleration conditions. The structural design is ingenious and the user experience is good.

[0047] like Fig.10 and Fig.11 As shown, in one embodiment, the labyrinth groove 14 is a transverse M-shaped groove, and an outlet 144 and an inlet 145 are respectively provided at both ends of the M-shaped groove, and the outlet 144 and the inlet 145 are oriented toward 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.

[0048] The labyrinth lock core 34 includes a spindle 341 movably disposed in the labyrinth groove 14. The spindle 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 spindle 341 enters and exits from the outlet 144 and the inlet 145; when the spindle 341 is located in the recess of the stopper 143, the drawer inner 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, thereby ensuring 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 block 142 is provided at a distance from the stopper 143 in the center of the M-shaped groove, and the wedge block 142 has a guide surface facing the outlet 144. The wedge block 142 is provided at a distance from the stopper 143, and the stopper 143 and the wedge block 142 are sandwiched to form the middle tip of the M-shape. When the mandrel 341 is located in the depression of the stopper 143 and the drawer inner bucket 1 moves inwardly relative to the drawer bottom plate 3, the mandrel 341 enters the outlet 144 along the guide surface, and then the drawer inner bucket 1 can be normally drawn out.

[0052] Specifically, the drawer inner bucket 1 is opened to the maximum and is still in the trumpet-shaped opening of the irregular guide strip 141. When the drawer inner bucket 1 is closed, the core shaft 341 is inserted into the M-shaped middle tip of the labyrinth groove 14, that is, the core shaft 341 hooks the stopper 143, and the drawer inner bucket 1 cannot be directly pulled out relative to the drawer bottom plate 3. When the drawer inner bucket 1 is opened normally, the drawer inner bucket 1 first moves inward for a period of unlocking stroke, and the core shaft 341 slides along the wedge block 142 to the channel corresponding to the outlet 144, and then the drawer inner bucket 1 is pulled out and opened normally.

[0053] When the drawer inner compartment 1 changes from an open state to a 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 M-shaped middle tip of the labyrinth groove 14. Fig.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 first, 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 reel 15, which is rotatably mounted on the front end of the drawer inner compartment 1, and the axis of the reel 15 is arranged in the left-right direction. The reel 15 is wound to set a coil spring 12, and the extended end of the coil spring 12 extends along the bottom of the drawer inner compartment 1 and is fixed to the rear of the drawer bottom plate 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 inner compartment 1 is closed, the coil spring 12 is in a tensioned state, that is, the coil spring 12 provides a pre-tightening force for the drawer inner compartment 1. The drawer inner compartment 1 always has a tendency to move backwards, but the labyrinth lock core 34 is tightly matched with the labyrinth groove 14, and the drawer inner compartment 1 cannot be directly opened backwards. To open the drawer inner compartment 1, it needs to move forward first, that is, the drawer inner compartment 1 needs to overcome the warning 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 make the drawer inner compartment 1 need to overcome the pre-tightening force of the coil spring 12 when the vehicle is in a deceleration condition, 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 comprises a rotating portion 331, a gravity portion 332, a protrusion 334 and a torsion spring 335 for resetting. The rotating portion 331 is rotatably arranged on the top surface of the drawer bottom plate 3, and the gravity portion 332 is suspended and connected to the rotating portion 331. The protrusion 334 is arranged on the top surface of the rotating portion 331, and the torsion spring 335 is arranged inside the rotating portion 331. The torsion spring 335 is used to limit the gravity portion 332 to swing only in the direction away from the inner bucket of the drawer, and is also used to facilitate the resetting of the gravity hammer 33 after swinging, that is, the gravity hammer 33 is in the initial state under the action of the torsion spring 335 when the vehicle is stationary or accelerating, and will 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, and after rotation, the protrusion 334 abuts against the drawer inner bucket 1 to stop 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: Fig. 9 As shown. The moment when the drawer inner bucket 1 moves forward under the action of inertia to overcome the preload force of the coil spring 12 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 moves forward under the action of inertia to overcome the preload force of the coil spring 12, and at this time, the fixed block 16 of the drawer inner bucket 1 is held by the protrusion 334. The gravity hammer 33 cooperates with the labyrinth lock, so that the drawer inner bucket 1 can be prevented from opening when accelerating or decelerating.

[0063] Specifically, the gravity hammer 33 further includes a connecting portion 333, and the connecting portion 333 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 does 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 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 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, and 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 also higher than the top surface of the connecting part 333, and 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 inner compartment 1 along the moving direction, and a gear damper 35 is provided on the upper surface of the drawer bottom plate 3, and the gear damper 35 is meshed with the rack 13. The gear damper 35 cooperates with the rack 13 to prevent the drawer inner compartment 1 from bouncing too quickly or even hitting the occupant after opening and unlocking.

[0068] In one embodiment, the drawer structure further includes an elastic sheet 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 a closed state, the elastic sheet 32 ​​is in a compressed state.

[0069] When the gear damper 35 meshes with the rack 13, there will generally be lubricating oil present. However, the lubricating oil will freeze in extremely cold and humid weather, which will cause obstacles to the opening of the drawer. In the drawer structure of the present application, the function of the spring piece 32 is that after the maze lock of the drawer inner compartment 1 is unlocked, the spring piece 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 cross section of the drawer bottom plate 3 is W-shaped, and a pair of lower slide rails 31 are arranged in two recesses of the W-shaped structure. The bottom of the drawer inner bucket 1 is V-shaped, and a pair of upper slide rails 11 are arranged on the bottom surfaces of both sides, and the upper slide rails 11 and the lower slide rails 31 match each other.

[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 compartment 1 is V-shaped. The two are tightly connected to each other, so that the connection stability of the drawer inner compartment 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 Fig.10 and Fig.11 As shown, in one embodiment, the labyrinth groove 14 is a transverse M-shaped groove, and an outlet 144 and an inlet 145 are respectively provided at both ends of the M-shaped groove, and the outlet 144 and the inlet 145 face 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 spindle 341 movably arranged in the labyrinth groove 14, and the spindle 341 at the rear end of the labyrinth lock core 34 is inserted upward into the labyrinth groove 14. When the drawer inner bucket 1 is closed or opened relative to the drawer bottom plate 3, the spindle 341 enters and exits from the outlet 144 and the inlet 145; when the spindle 341 is located in the depression of the stopper 143, the drawer inner bucket 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, thereby ensuring 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 at a distance from the stopper 143 in the center of the M-shaped groove, 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 to form an M-shaped middle tip. 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 normally drawn out.

[0075] Specifically, the drawer inner bucket 1 is opened to the maximum and is still in the trumpet-shaped opening of the irregular guide strip 141. When the drawer inner bucket 1 is closed, the core shaft 341 is inserted into the M-shaped middle tip of the labyrinth groove 14, that is, the core shaft 341 hooks the triangular stopper 143, and the drawer inner bucket 1 cannot be directly pulled out relative to the drawer bottom plate 3. When the drawer inner bucket 1 is opened normally, the drawer inner bucket 1 first moves inward for a period of unlocking stroke, and the core shaft 341 slides along the wedge block 142 to the channel corresponding to the outlet 144, and then the drawer inner bucket 1 is pulled out and opened normally.

[0076] When the drawer inner compartment 1 changes from an open state to a 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 triangular stopper 143, and then enters the M-shaped middle tip of the labyrinth groove 14. Fig.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 first, 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 the automobile, in one embodiment, the drawer structure further includes a reel 15, which is rotatably mounted on the front end surface of the drawer inner compartment 1, and the axis of the reel 15 is arranged in the left and right direction. The reel 15 is curled to set a coil spring 12, and the protruding end of the coil spring 12 extends along the bottom of the drawer inner compartment 1 and is fixed to the rear of the drawer chassis 3. 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. When the drawer inner compartment 1 is closed, the coil spring 12 is in a tensioned state, that is, the coil spring 12 provides a pre-tightening force for the drawer inner compartment 1, and the drawer inner compartment 1 always has a backward tendency, but the labyrinth lock core 34 is tightly matched with the labyrinth groove 14, and the drawer inner compartment 1 cannot be opened directly backward. To open the drawer inner compartment 1, it needs to move forward first, that is, the drawer inner compartment 1 needs to overcome the warning force 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 compartment 1 is in a closed state, the coil spring 12 is in a tensioned state, providing a pre-tightening force for the drawer compartment 1, so that even if the drawer compartment 1 has an unlocking travel space for inward displacement (necessary to unlock the maze lock), the drawer compartment 1 will not shake relative to the drawer chassis 3 when closed; at the same time, the coil spring 12 can also make the drawer compartment 1 need to overcome the pre-tightening force of the coil spring 12 when the vehicle is in a deceleration condition, so that the forward movement of the drawer compartment 1 under the action of inertia always occurs after the gravity hammer 33 swings forward, laying the foundation for preventing the drawer compartment 1 from bouncing open during deceleration.

[0080] Furthermore, the gravity hammer 33 also includes a rotating part 331, a gravity part 332, a protrusion 334 and a torsion spring 335 for resetting. The rotating part 331 is rotatably arranged on the top surface of the drawer bottom plate 3, and the gravity part 332 is suspended and connected to the rotating part 331. The protrusion 334 is arranged on the top surface of the rotating part 331, and the torsion spring 335 is arranged in the rotating part 331. The torsion spring 335 is used to limit the gravity part 332 to swing only in the direction away from the inner bucket of the drawer, and is also used to facilitate the resetting of the gravity hammer 33 after swinging, that is, the gravity hammer 33 is in the initial state under the action of the torsion spring 335 when the vehicle is stationary or accelerating, and will not swing.

[0081] When the vehicle deceleration reaches the 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 the protruding part 334 abuts against the drawer inner bucket 1 after rotation, 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 90 degrees under the action of inertia. The state of the gravity hammer 33 swinging forward 90 degrees is shown in FIG. Fig. 9 As shown. The moment when the drawer inner bucket 1 moves forward under the action of inertia to overcome the preload force of the coil spring 12 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 moves forward under the action of inertia to overcome the preload force of the coil spring 12, and 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. 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 does 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, and the structural design is ingenious.
