Vehicle-mounted drawer structure and automobile Cross-reference to Related Applications

[0001] This application claims priority to Chinese Patent Application No. 2024108641869, filed on June 30, 2024, the entire contents of which are incorporated herein by reference. TECHNICAL FIELD

[0002] The present disclosure belongs to the technical field of drawer design, and in particular relates to a vehicle-mounted drawer structure and an automobile. BACKGROUND

[0003] At present, with the upgrading of automobiles, people have higher and higher requirements for vehicle-mounted drawers. The vehicle-mounted drawer not only needs to meet the demand of containing articles, but also needs to be provided with a damping member to improve the ejection speed of the drawer, so as to prevent the drawer from ejecting too fast, making too much noise, or colliding with the passenger.

[0004] In related technologies, the traditional vehicle-mounted drawer with a damping structure is usually provided with a containing cavity in the automobile, a drawer is arranged in the containing cavity, and a damping buffer is arranged between the drawer and the inner wall of the containing cavity. Through the damping effect of the damping buffer, the moving speed of the drawer is reduced when the drawer is pulled out or retracted into the containing cavity, so that the drawer moves slowly during use, and the use is safer.

[0005] However, the traditional vehicle-mounted drawer with a damping structure still has the following defects: during the driving of the automobile, the drawer may automatically eject from the containing cavity under the action of inertia, which may cause customer complaints. SUMMARY

[0006] The present disclosure aims to solve the problem that the drawer may automatically eject under the action of inertia during the acceleration and deceleration of the automobile. To this end, a vehicle-mounted drawer structure and an automobile are provided.

[0007] According to a first aspect of the present disclosure, a vehicle-mounted drawer structure is provided, comprising:

[0008] a drawer chassis provided with a labyrinth lock core;

[0009] a drawer inner cup provided with a labyrinth groove matched with the labyrinth lock core, the drawer inner cup being slidably arranged on the drawer chassis through the labyrinth groove and the labyrinth lock core;

[0010] a gravity hammer rotatably arranged on the drawer chassis, the gravity hammer having a protruding portion;

[0011] When the drawer inner cup is closed, the protruding portion is located outside the drawer inner cup; when the gravity hammer swings forward under the action of inertia, the protruding portion rotates to the front end of the drawer inner cup and stops the drawer inner cup from moving forward.

[0012] According to a second aspect of the present disclosure, the present disclosure provides an automobile comprising the vehicle-mounted drawer structure described above. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0027] In order to enable persons skilled in the art to better understand the present disclosure, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by persons skilled in the art without creative labor fall within the scope of protection of the present disclosure.

[0028] For the convenience of introduction, the front of the car is defined as the front, the rear of the car is defined as the rear, and the width direction of the car is defined as the left-right direction. After understanding the above directions, the content of the present disclosure will be explained in detail.

[0029] According to the present disclosure, a vehicle-mounted drawer structure and a vehicle are provided, which solve the problem that the vehicle-mounted drawer is automatically opened under the action of inertia under the acceleration and deceleration working conditions of the vehicle.

[0030] The technical solutions of the present disclosure will be described below in conjunction with the accompanying drawings and reference to the embodiments.

[0031] As shown in FIGS. 1-12, the first aspect embodiment of the present disclosure provides a vehicle-mounted drawer structure, which can include a drawer chassis 3, a drawer inner pot 1, and a gravity hammer 33.

[0032] The drawer chassis 3 is provided with a labyrinth lock core 34, and the drawer inner pot 1 is provided with a labyrinth groove 14 cooperating with the labyrinth lock core 34. Therefore, when the drawer inner pot 1 is in a closed state, the drawer inner pot 1 can be locked by the labyrinth groove 14 and the labyrinth lock core 34. In some embodiments, 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 pot 1, so as to realize the arrangement of the labyrinth lock core 34 and the labyrinth groove 14.

[0033] The gravity hammer 33 is rotatably arranged on the drawer bottom plate 3 to switch between the initial state and the blocking state. The gravity hammer 33 has a protruding part 334. When the drawer inner bucket 1 is in the closed state: in the static, uniform speed and acceleration working conditions of the automobile, the gravity hammer 33 is in the initial state as shown in FIG. 8, and the protruding part 334 is located outside the drawer inner bucket 1 (see FIG. 8). In the deceleration working condition of the automobile, the gravity hammer 33 rotates to the blocking state under the action of inertia, drives the protruding part 334 to rotate to the front end of the drawer inner bucket 1 (see FIG. 9), and abuts against the drawer inner bucket 1 to block the forward movement of the drawer inner bucket 1.

[0034] Specifically, the gravity hammer 33 is always in the initial state as shown in FIG. 8 when the automobile is static or is accelerating; after the gravity hammer 33 swings forward under the action of inertia in the deceleration working condition of the automobile, the gravity hammer 33 is in the swung state as shown in FIG. 9.

[0035] The vehicle-mounted drawer structure of the present disclosure is provided with the cooperating labyrinth groove 14 and labyrinth lock core 34 between the drawer inner bucket 1 and the drawer bottom plate 3, so that the drawer inner bucket 1 moves forward and then backward relative to the drawer bottom plate 3 to realize the normal switching of the drawer inner bucket 1 from the closed state to the open state. When the drawer inner bucket 1 is in the closed state, in the acceleration working condition of the automobile, the drawer inner bucket 1 has a tendency to move backward relative to the drawer bottom plate 3 and open under the action of inertia, but the labyrinth lock core 34 hooks the rear slot wall of the labyrinth groove 14, thereby limiting the backward withdrawal of the drawer inner bucket 1 relative to the drawer bottom plate 3, and ensuring that the drawer inner bucket 1 does not pop open in the acceleration working condition of the automobile; in the deceleration working condition of the automobile, the drawer inner bucket 1 has a tendency to move forward relative to the drawer bottom plate 3 under the action of inertia, and since the gravity hammer 33 rotates under the action of inertia, the protruding part 334 is driven to rotate to the front end of the drawer inner bucket 1 to block the forward movement of the drawer inner bucket 1, effectively preventing the forward movement of the drawer inner bucket 1 and ensuring the cooperation of the labyrinth lock core 34 and the labyrinth groove 14. Therefore, the cooperation of the labyrinth groove 14, the labyrinth lock core 34 and the gravity hammer 33 can effectively solve the problem of automatic popping open of the drawer in the closed state in the acceleration and deceleration working conditions of the automobile, and the structure design is ingenious and the user experience is good.

[0036] The drawer inner bucket 1 is slidably arranged on the drawer bottom plate 3 to switch between the open state and the closed state, and in the open state, articles can be placed or taken out of the drawer inner bucket 1, and in the closed state, the articles can be stored and the space in the automobile can be released. For convenience of introduction, the following explanations are made with the drawer inner bucket 1 sliding forward to the top of the drawer bottom plate 3 as the closed state and the drawer inner bucket 1 sliding backward relative to the drawer bottom plate 3 to the maximum displacement as the open state.

[0037] As shown in FIG. 10 and FIG. 11, in some embodiments, the labyrinth groove 14 is a guide groove that provides a moving path for the labyrinth lock cylinder 34, which can be a transverse M-shaped groove, i.e., the M-shaped groove extends along the width direction of the vehicle, and the two ends of the M-shaped groove are respectively provided with an outlet 144 and an inlet 145, which are directed towards the direction of the gravity hammer 33, i.e., the outlet 144 and the inlet 145 are directed towards the front end of the drawer inner pot 1. A recessed stop block 143 corresponding to the middle tip of the M shape is arranged between the outlet 144 and the inlet 145 in the M-shaped groove, that is, the drawer inner pot 1 is provided with a stop block 143 arranged in the labyrinth groove 14, and the stop block 143 has a recess. The labyrinth lock cylinder 34 includes a shaft 341 movably arranged in the labyrinth groove 14, and the shaft 341 at the rear end of the labyrinth lock cylinder 34 is inserted upward into the labyrinth groove 14.

[0038] The M-shaped groove extends along the width direction of the vehicle, so that the drawer inner pot 1 has a moving trajectory of first forward and then backward relative to the drawer chassis 3. The outlet 144 and the inlet 145 are directed towards the front end of the drawer inner pot 1, and when the drawer inner pot 1 slides relative to the drawer chassis 3 to switch between the closed state and the open state, it is convenient for the shaft 341 to exit the labyrinth groove 14 from the outlet 144 and enter the labyrinth groove 14 from the inlet 145; in the case that the drawer inner pot 1 is in the closed state, the shaft 341 is located in the recess of the stop block 143, and if the vehicle accelerates, the shaft 341 can hook the recess wall at the recess, thereby limiting the drawer inner pot 1 from being pulled out backward relative to the drawer chassis 3, and ensuring that the drawer inner pot 1 does not pop open under the condition of vehicle acceleration, and the drawer inner pot 1 is locked with the drawer chassis 3. When the drawer inner pot 1 is closed, the shaft 341 is inserted into the recess of the stop block 143 in the labyrinth groove 14 (i.e., at the middle tip of the M shape), and the shaft 341 hooks the drawer inner pot 1 through the labyrinth groove 14, so that the drawer inner pot 1 cannot be pulled out relative to the drawer chassis 3, and it can be ensured that the drawer inner pot 1 does not pop open under the inertial effect of vehicle acceleration.

[0039] In some embodiments, the bottom surface of the drawer inner pot 1 can be provided with an irregular guide strip 141, a stop block 143 and a wedge-shaped block 142 that protrude downward, the irregular guide strip 141 and the stop block 143 are connected, and the irregular guide strip 141, the stop block 143 and the wedge-shaped block 142 enclose the labyrinth groove 14. The irregular guide strip 141 extends forward along the outlet 144 and the inlet 145 to form a horn-shaped opening, that is, the two ends of the irregular guide strip 141 protrude beyond the stop block 143 towards the front end of the drawer inner pot 1, and the portions of the two ends of the irregular guide strip 141 that protrude beyond the stop block 143 towards the front end of the drawer inner pot 1 enclose a horn-shaped opening for guiding the shaft 341.

[0040] The M-shaped slot has a wedge-shaped block 142 spaced from the block 143 in the middle. The wedge-shaped block 142 has a guide surface facing the outlet 144. The wedge-shaped block 142 is spaced from the block 143. The block 143 and the wedge-shaped block 142 form the middle tip of the labyrinth slot 14. When the shaft 341 is located in the recess of the block 143, the drawer inner bucket 1 moves forward relative to the drawer chassis 3. In this case, the shaft 341 moves along the guide surface to the outlet 144, thereby achieving the unlocking of the drawer inner bucket 1 and the drawer chassis 3. After that, the drawer inner bucket 1 can be normally pulled out to switch to the open state.

[0041] When the drawer inner bucket 1 moves backward relative to the drawer chassis 3 to the limit position, that is, the drawer inner bucket 1 is opened to the maximum, the shaft 341 is still in the trumpet-shaped opening of the irregular guide strip 141. When the drawer inner bucket 1 is closed, the shaft 341 is inserted into the M-shaped middle tip of the labyrinth slot 14, that is, the shaft 341 hooks the recess of the block 143, and the drawer inner bucket 1 cannot be directly pulled out relative to the drawer chassis 3. When the drawer inner bucket 1 is normally opened, the drawer inner bucket 1 first moves forward by a certain unlocking stroke, and the shaft 341 moves along the guide surface of the wedge-shaped block 142 to the channel corresponding to the outlet 144. After that, the drawer inner bucket 1 is pulled out, and the drawer inner bucket 1 is in the open state.

[0042] When the drawer inner bucket 1 is switched from the open state to the closed state, the shaft 341 is guided by the trumpet-shaped opening of the irregular guide strip 141 to approach the block 143, and then enters the inlet 145 along the guide slope of the block 143, and then enters the M-shaped middle tip of the labyrinth slot 14. As shown in FIG. 11, after the shaft 341 enters the innermost part of the inlet 145, it can only first reach the M-shaped middle tip of the labyrinth slot 14, and then open the drawer inner bucket 1 forward and backward.

[0043] In some embodiments, the labyrinth slot 14 can include a first slot segment, a second slot segment, a third slot segment, and a fourth slot segment sequentially connected in the direction from the inlet 145 to the outlet 144. The second slot segment and the third slot segment are arranged at an angle, and the connection between the second slot segment and the third slot segment is closer to the front end of the drawer inner bucket 1. The block 143 and the wedge-shaped block 142 are located at the connection between the second slot segment and the third slot segment, and are oppositely arranged along the length direction of the automobile. The recess of the block 143 has a first recess wall and a second recess wall. The wedge-shaped block 142 has a limiting surface and a guide surface. The limiting surface and the first recess wall respectively constitute two slot walls of the second slot segment, and the guide surface and the second recess wall respectively constitute two slot walls of the third slot segment, thereby achieving the arrangement of the M-shaped slot and the block 143.

[0044] In some embodiments, the labyrinth lock core 34 can further include a rotating shaft and a connecting section, one end of the rotating shaft is rotationally connected to the drawer bottom plate 3, the other end is connected to the connecting section, the core shaft 341 is connected to the connecting section, and the core shaft 341 is connected with the rotating shaft through the connecting section, so that the core shaft 341 makes a circular motion with the rotating shaft as the center, and the position is adjustable to adapt to the curved distribution of the labyrinth groove 14, so that the drawer inner bucket 1 moves only along the length direction of the automobile relative to the drawer bottom plate 3, without left and right shaking, better stability, and good user experience.

[0045] The vehicle-mounted drawer structure of the present disclosure is provided with the labyrinth lock core 34 and the labyrinth groove 14, which can effectively prevent the drawer inner bucket 1 from automatically opening under the action of inertia during the acceleration of the automobile.

[0046] In some embodiments, the vehicle-mounted drawer structure can further include a winding drum 15, which is rotationally installed at the front end of the drawer inner bucket 1, and the axis of the winding drum 15 is arranged along the width direction of the automobile, i.e. the left and right direction. The winding drum 15 is externally curled with a coil spring 12, the extending end of the coil spring 12 extends along the length direction of the automobile at the bottom of the drawer inner bucket 1, and is fixed to the rear end of the drawer bottom plate 3.

[0047] The labyrinth groove 14 and the labyrinth lock core 34 form a labyrinth lock, and when the drawer inner bucket 1 is in a closed state, the labyrinth lock is in a locked state, and the coil spring 12 is in a tensioned state.

[0048] When the drawer inner bucket 1 is in a closed state, the coil spring 12 is in a tensioned state, providing a pre-tightening force for the drawer inner bucket 1, so that the drawer inner bucket 1 always has a tendency to move backward relative to the drawer bottom plate 3, but the labyrinth lock core 34 tightly fits the labyrinth groove 14, and the core shaft 341 can hook the rear concave wall of the stop block 341, so that the drawer inner bucket 1 cannot be directly opened backward, thereby realizing stable retention of the drawer inner bucket 1 in a closed state. When the drawer inner bucket 1 is switched from a closed state to an open state, the drawer inner bucket 1 needs to move forward relative to the drawer bottom plate 3, at which time the drawer inner bucket 1 needs to overcome the pre-tightening force provided by the coil spring 12.

[0049] When the drawer inner pot 1 is in the closed state, the coil spring 12 is in the tension state, providing pre-tightening force for the drawer inner pot 1, so that even if the drawer inner pot 1 has a forward displacement unlocking travel space (required to unlock the labyrinth lock), the drawer inner pot 1 will not shake relative to the drawer chassis 3 in the closed state, improving the stability of the vehicle-mounted drawer structure. At the same time, the coil spring 12 is also arranged to enable the vehicle to move in a deceleration working condition. If the inertia is less than the pre-tightening force of the coil spring 12, the drawer inner pot 1 will not move forward relative to the drawer chassis 3. If the inertia is greater than the pre-tightening force of the coil spring 12, the drawer inner pot 1 needs to overcome the pre-tightening force of the coil spring 12 first, and then move forward, reserving time for the gravity hammer 33 to switch from the initial state to the blocking state. That is, in the deceleration working condition of the vehicle, the forward movement of the drawer inner pot 1 relative to the drawer chassis 3 always occurs after the forward swing of the gravity hammer 33, laying the foundation for avoiding the drawer inner pot 1 from being opened in the deceleration working condition.

[0050] In some embodiments, the vehicle-mounted drawer structure can further include a rectangular drawer frame 2 fixedly arranged at the rear of the drawer chassis 3, and the drawer inner pot 1 passes through the drawer frame 2 and is located at both sides of the drawer frame 2 along the length direction of the vehicle.

[0051] In one embodiment, the gravity hammer 33 can further include a rotating part 331, a gravity part 332, a protruding part 334, and a torsional spring 335 for resetting. The rotating part 331 is rotatably arranged on the top surface of the drawer chassis 3, and the gravity part 332 is connected to the rotating part 331 in a cantilevered manner. The protruding part 334 is arranged on the top surface of the rotating part 331, and the torsional spring 335 is arranged in the rotating part 331. The torsional spring 335 is used to limit the gravity part 332 to swing only in a direction away from the drawer inner pot, and is also used to facilitate the resetting of the gravity hammer 33 after swinging, that is, the gravity hammer 33 switches from the blocking state to the initial state after the vehicle switches from deceleration to static or uniform speed working condition. And in the static, uniform speed or acceleration working condition of the vehicle, the gravity hammer 33 remains in the initial state under the action of the torsional spring 335 and does not swing.

[0052] When the deceleration of the vehicle reaches a set threshold, the gravity part 332 of the gravity hammer 33 swings forward under the action of inertia with the rotating part 331 as the swing center. The gravity part 332 swings and drives the rotating part 331 to rotate. After rotation, the protruding part 334 abuts against the drawer inner pot 1, blocking the forward movement of the drawer inner pot 1, so that the mandrel 341 cannot be separated from the labyrinth groove 14.

[0053] In some embodiments, when the car is decelerating, the gravity part 332 of the gravity hammer 33 swings forward under the action of inertia, and can swing 90°, of course, it can also swing 80° or 85°, etc. The state of the gravity hammer 33 swinging forward 90° is shown in FIG. 9. The drawer inner pot 1 moves forward under the action of inertia later than the time when the gravity hammer 33 swings to the position, that is, after the gravity hammer 33 swings to the position (i.e. 90°), the drawer inner pot 1 moves forward under the action of inertia against the pre-tightening force of the coil spring 12, at this time, the front end of the drawer inner pot 1 is abutted by the protruding part 334. The gravity hammer 33 and the labyrinth lock cooperate with each other, so that the drawer inner pot 1 can be prevented from opening under the conditions of car acceleration and deceleration.

[0054] In some embodiments, the gravity hammer 33 can further include a connecting part 333 connecting the rotating part 331 and the gravity part 332. Specifically, the gravity hammer 33 is located at the front of the drawer chassis 3, and the labyrinth lock core 34 is located at the rear of the drawer chassis 3.

[0055] The vehicle-mounted drawer structure of the present disclosure is provided with a gravity hammer 33, which remains in the initial state under the action of the torsion spring 335 when the car is stationary, uniform speed or accelerating, and will not swing; when the deceleration of the car reaches a set threshold, the gravity part 332 of the gravity hammer 33 swings forward under the action of inertia, drives the rotating part 331 to rotate, and after rotation, the protruding part 334 stops the drawer inner pot 1 from moving forward, so that the mandrel 341 cannot be separated from the labyrinth groove 14; more importantly, the time when the drawer inner pot 1 moves forward under the action of inertia against the pre-tightening force of the coil spring 12 is later than the time when the gravity hammer 33 switches to the stopping state, so that the gravity hammer 33 can timely stop the drawer inner pot 1 when the car is decelerating, preventing the drawer inner pot 1 from automatically opening, and the structure design is ingenious.

[0056] In some embodiments, the front end of the drawer inner pot 1 can be provided with two fixed blocks 16, and the winding drum 15 is rotatably installed between the two fixed blocks 16, one of which is used to abut the protruding part 334 after rotation, so that the fixed block 16 not only realizes the installation function of the winding drum 15, but also can cooperate with the protruding part 334 to stop under the condition of car deceleration, which is rich in function and simple in structure.

[0057] In some embodiments, when the car is in a stationary, uniform speed or acceleration condition, and the drawer inner bucket 1 is in a closed state, the protruding part 334 is arranged away from the fixed block 16 along the direction perpendicular to the movement direction of the drawer inner bucket, that is, along the width direction of the car. The protruding part 334 and the fixed block 16 do not interfere with each other, and do not affect the forward movement of the drawer inner bucket 1 relative to the drawer chassis 3 during the unlocking process of the labyrinth lock core 34 and the labyrinth groove 14. The opening and closing process of the drawer inner bucket 1 is more smooth. The bottom surface of the fixed block 16 is higher than the top surface 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 protruding part 334. That is, along the height direction, the fixed block 16 is arranged away from other structures in the gravity hammer 33 except the protruding part 334. In this way, when the drawer inner bucket 1 needs to move forward relative to the drawer chassis 3 during normal opening of the drawer inner bucket 1, the fixed block 16 on the front end surface of the drawer inner bucket 1 passes above the rotating part 331 and the gravity part 332. At this time, the fixed block 16 is not blocked, and the opening and closing process of the drawer inner bucket 1 is more smooth.

[0058] In some embodiments, the bottom surface of the drawer inner bucket 1 can be provided with a rack 13 extending along the movement direction of the drawer inner bucket 1, and the upper surface of the drawer chassis 3 can be provided with a gear damping part 35 engaged with the rack 13. The gear damping part 35 and the rack 13 cooperate to reduce the risk of the drawer inner bucket 1 being opened too quickly or even hitting the occupant under the restoring force of the coil spring 12 after the labyrinth lock core 34 and the labyrinth groove 14 are unlocked.

[0059] In some embodiments, the vehicle-mounted drawer structure can further include a spring piece 32, one end of the spring piece 32 being fixed to the front top surface of the drawer chassis 3, and the other end of the spring piece 32 being inclined and abutting against the front end surface of the drawer inner bucket 1. When the drawer inner bucket 1 is in a closed state, the spring piece 32 is in a compressed state.

[0060] The transmission structure in which the gear damping part 35 is engaged with the rack 13 generally has lubricating oil, but the lubricating oil may freeze in extremely cold and humid weather, causing obstacles to the opening of the drawer inner bucket 1. After the labyrinth lock core 34 and the labyrinth groove 14 are unlocked, the drawer inner bucket 1 can be bounced back by the restoring force of the spring piece 32, making it more convenient to open the drawer inner bucket 1 in extremely cold and humid weather. Of course, during the movement of the drawer inner bucket 1 relative to the drawer chassis 3, the elastic force of the spring piece 32 needs to be overcome.

[0061] In some embodiments, the drawer chassis 3 is provided with two lower slide rails 31, and the bottom of the drawer inner bucket 1 is provided with one upper slide rail 11 on each side along the width direction of the car. The upper slide rail 11 and the lower slide rail 31 correspond to each other and match each other, improving the stability of the sliding of the drawer inner bucket 1 relative to the drawer chassis 3.

[0062] In some embodiments, the cross section of the drawer chassis 3 can be W-shaped to form two recesses on the drawer chassis 3 extending along the moving direction of the drawer inner bucket 1, and the two upper slide rails 11 are respectively located in the two recesses, and the bottom cross section of the drawer inner bucket 1 is inverted V-shaped. The vehicle-mounted drawer structure of the present disclosure, the cross section of the drawer chassis 3 is W-shaped, and the cross section of the bottom of the drawer inner bucket 1 is inverted V-shaped, which are matched with each other, so that the connection stability of the drawer inner bucket 1 and the drawer chassis 3 is good, which can not only meet the abuse force requirement in the up-down direction, but also more importantly meet the abuse force requirement in the left-right direction, and the structure is compact and the space utilization rate is high.

[0063] In the second aspect of the present disclosure, an automobile is provided, which comprises the vehicle-mounted drawer structure of any one of the embodiments of the first aspect.

[0064] Regarding the automobile, as shown in FIGS. 10 and 11, in some embodiments, the labyrinth groove 14, as a guide groove for providing a moving path of the labyrinth lock core 34, can be a transverse M-shaped groove, that is, the M-shaped groove extends along the width direction of the automobile, and the M-shaped groove is respectively provided with an outlet 144 and an inlet 145 at two ends, and the outlet 144 and the inlet 145 are directed to the direction of the gravity hammer 33, that is, the outlet 144 and the inlet 145 are directed to the front end of the drawer inner bucket 1. A recessed stop block 143 corresponding to the middle sharp end of the M-shaped groove is arranged between the outlet 144 and the inlet 145 in the M-shaped groove, that is, the drawer inner bucket 1 is provided with the stop block 143 located in the labyrinth groove 14, and the stop block 143 has a recess. The labyrinth lock core 34 can include a shaft 341 movably arranged in the labyrinth groove 14, and the shaft 341 at the rear end of the labyrinth lock core 34 is inserted upward into the labyrinth groove 14. The M-shaped groove extends along the width direction of the automobile to make the movement trajectory of the drawer inner bucket 1 relative to the drawer chassis 3 first forward and then backward. The outlet 144 and the inlet 145 are directed to the front end of the drawer inner bucket 1, and when the drawer inner bucket 1 slides relative to the drawer chassis 3 to switch between the closed state and the open state, it is convenient for the shaft 341 to exit the labyrinth groove 14 from the outlet 144 and enter the labyrinth groove 14 from the inlet 145; in the case that the drawer inner bucket 1 is in the closed state, when the shaft 341 is located in the recess of the stop block 143, if the automobile accelerates, the shaft 341 can hook the recess wall at the recess to limit the drawer inner bucket 1 from being pulled out backward relative to the drawer chassis 3, so as to ensure that the drawer inner bucket 1 does not pop open under the acceleration working condition of the automobile, and the drawer inner bucket 1 is locked with the drawer chassis 3. When the drawer inner bucket 1 is closed, the shaft 341 is inserted into the recess of the stop block 143 in the labyrinth groove 14 (that is, the middle sharp end of the M-shaped groove), and the shaft 341 hooks the drawer inner bucket 1 through the labyrinth groove 14, so that the drawer inner bucket 1 cannot be pulled out outward relative to the drawer chassis 3, and the drawer inner bucket 1 can be ensured not to pop open under the inertial effect of the acceleration working condition of the automobile.

[0065] In some embodiments, the bottom surface of the drawer inner pot 1 can be provided with an irregular guide strip 141, a stop block 143 and a wedge-shaped block 142. The irregular guide strip 141 and the stop block 143 are connected, and the irregular guide strip 141, the stop block 143 and the wedge-shaped block 142 enclose a labyrinth groove 14. The M-shaped groove is enclosed by the irregular guide strip 141, and the irregular guide strip 141 extends forward at the outlet 144 and the inlet 145 to form a horn-shaped opening, that is, the two ends of the irregular guide strip 141 extend beyond the stop block 143 in the forward direction of the drawer inner pot 1, and the portions of the two ends of the irregular guide strip 141 extending beyond the stop block 143 in the forward direction of the drawer inner pot 1 enclose a horn-shaped opening for guiding the mandrel 341.

[0066] The M-shaped groove is centrally spaced from the stop block 143 by a wedge-shaped block 142, and the wedge-shaped block 142 has a guide surface facing the outlet 144. The wedge-shaped block 142 is oppositely spaced from the triangular stop block 143, and the stop block 143 and the wedge-shaped block 142 sandwich the middle tip of the labyrinth groove 14. When the mandrel 341 is located in the recess of the stop block 143, and the drawer inner pot 1 moves forward relative to the drawer chassis 3, the mandrel 341 moves along the guide surface of the wedge-shaped block 142 to the outlet 144, thereby achieving unlocking of the drawer inner pot 1 relative to the drawer chassis 3, and then the drawer inner pot 1 can be normally pulled out to switch to an open state.

[0067] When the drawer inner pot 1 moves relative to the drawer chassis 3 to the limit position, that is, the drawer inner pot 1 is opened to the maximum, the mandrel 341 is still in the horn-shaped opening of the irregular guide strip 141. When the drawer inner pot 1 is closed, the mandrel 341 is inserted into the M-shaped middle tip of the labyrinth groove 14, that is, the mandrel 341 hooks the recess of the triangular stop block 143, and the drawer inner pot 1 cannot be directly pulled out relative to the drawer chassis 3. When the drawer inner pot 1 is normally opened, the drawer inner pot 1 first moves forward by a certain unlocking stroke, the mandrel 341 moves along the guide surface of the wedge-shaped block 142 to the channel corresponding to the outlet 144, and then the drawer inner pot 1 is pulled out, and the drawer inner pot 1 is in an open state.

[0068] When the drawer inner pot 1 is switched from the open state to the closed state, the mandrel 341 approaches the stop block 143 under the guidance of the horn-shaped opening of the irregular guide strip 141, and then enters the inlet 145 along the guide slope of the triangular stop block 143, and then enters the M-shaped middle tip of the labyrinth groove 14. As shown in FIG. 11, after the mandrel 341 enters the innermost part of the inlet 145, it can only first reach the M-shaped middle tip of the labyrinth groove 14, and then open the drawer inner pot 1 forward and then backward.

[0069] The automobile of the present disclosure can effectively prevent the drawer inner pot 1 from automatically opening under the action of inertia during the acceleration of the automobile.

[0070] As to the car, in some embodiments, the drawer structure of the car can further comprise a winding drum 15 rotatably mounted at the front end of the drawer inner bucket 1, and the axis of the winding drum 15 is arranged along the width direction of the car, i.e. the left-right direction. The winding drum 15 is externally wound by a winding spring 12, the extended end of the winding spring 12 extends along the length direction of the car at the bottom of the drawer inner bucket 1, and is fixed at the rear end of the drawer bottom plate 3. The labyrinth slot 14 and the labyrinth lock core 34 form a labyrinth lock, and when the drawer inner bucket 1 is in the closed state, the labyrinth lock is in the locked state, and the winding spring 12 is in the tension state. When the drawer inner bucket 1 is in the closed state, the winding spring 12 is in the tension state, which provides a pre-tightening force for the drawer inner bucket 1, so that the drawer inner bucket 1 always has a tendency to move backward relative to the drawer bottom plate 3, but the labyrinth lock core 34 tightly fits the labyrinth slot 14, and the core shaft 341 can hook the rear concave wall of the stop block 341, so that the drawer inner bucket 1 cannot be directly opened backward, thereby realizing the stable retention of the drawer inner bucket 1 in the closed state. When the drawer inner bucket 1 is switched from the closed state to the open state, the operator needs to operate to overcome the pre-tightening force provided by the winding spring 12, so that the drawer inner bucket 1 first moves forward relative to the drawer bottom plate 3, and then moves backward, at which time the drawer inner bucket 1 needs to overcome the pre-tightening force provided by the winding spring 12.

[0071] The car of the present disclosure, the drawer structure of the car is provided with a winding spring 12, and when the drawer inner bucket 1 is in the closed state, the winding spring 12 is in the tension state, which provides a pre-tightening force for the drawer inner bucket 1, so that even if the drawer inner bucket 1 has a forward displacement unlocking travel space (required to unlock the labyrinth lock) relative to the drawer bottom plate 3, the drawer inner bucket 1 will not shake relative to the drawer bottom plate 3 in the closed state, thereby improving the stability of the drawer structure of the car. At the same time, the arrangement of the winding spring 12 can also make the car in the deceleration working condition, if the inertia is less than the pre-tightening force of the winding spring 12, the drawer inner bucket 1 will not move forward relative to the drawer bottom plate 3, if the inertia is greater than the pre-tightening force of the winding spring 12, the drawer inner bucket 1 needs to overcome the pre-tightening force of the winding spring 12 first, and then move forward, thereby reserving time for the gravity hammer 33 to switch from the initial state to the blocking state, that is, in the deceleration working condition of the car, the forward movement of the drawer inner bucket 1 relative to the drawer bottom plate 3 always occurs after the forward swing of the gravity hammer 33, thereby laying a foundation for avoiding the opening of the drawer inner bucket 1 in the deceleration working condition.

[0072] Further, the gravity hammer 33 can further include a rotating part 331, a gravity part 332, a protruding part 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 suspendedly connected to the rotating part 331. The protruding part 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 a direction away from the drawer inner pot, and is also used to facilitate the resetting of the gravity hammer 33 after swinging, that is, after the vehicle is switched from deceleration to static or uniform speed working condition, the gravity hammer 33 is switched from the blocking state to the initial state. Moreover, under the static, uniform speed or acceleration working condition of the vehicle, the gravity hammer 33 remains in the initial state under the action of the torsion spring 335 and cannot swing.

[0073] When the deceleration of the vehicle reaches the set threshold, the gravity part 332 of the gravity hammer 33 swings forward under the action of inertia with the rotating part 331 as the swing center. The gravity part 332 swings and drives the rotating part 331 to rotate. After rotation, the protruding part 334 abuts against the drawer inner pot 1, blocks the forward movement of the drawer inner pot 1, and makes the mandrel 341 unable to separate from the labyrinth groove 14. In some embodiments, under the deceleration working condition of the vehicle, the gravity hammer 33 swings forward under the action of inertia, and the gravity hammer 33 swings 90°. The state of the gravity hammer 33 swinging 90° is shown in FIG. 9. The time when the drawer inner pot 1 moves forward under the action of inertia and overcomes the pre-tightening force of the coil spring 12 is later than the time when the gravity hammer 33 swings into place. That is, after the gravity hammer 33 swings into place (i.e., swings 90°), the drawer inner pot 1 moves forward under the action of inertia and overcomes the pre-tightening force of the coil spring 12. At this time, the fixed block 16 of the drawer inner pot 1 is abutted by the protruding part 334. The gravity hammer 33 cooperates with the labyrinth lock to prevent the drawer inner pot 1 from opening automatically under the acceleration and deceleration working conditions of the vehicle. Specifically, the gravity hammer 33 can further include a connecting part 333 connecting the rotating part 331 and the gravity part 332. In some embodiments, the gravity hammer 33 can be located at the front of the drawer bottom plate 3, and the labyrinth lock can be located at the rear of the drawer bottom plate 3.

[0074] The vehicle of the present disclosure is provided with the gravity hammer 33. Under the static, uniform speed or acceleration working condition of the vehicle, the gravity hammer 33 remains in the initial state under the action of the torsion spring 335 and cannot swing. When the deceleration of the vehicle reaches the set threshold, the gravity part 332 of the gravity hammer 33 swings forward under the action of inertia, drives the rotating part 331 to rotate, and after rotation, the protruding part 334 blocks the forward movement of the drawer inner pot 1, so that the mandrel 341 cannot separate from the labyrinth groove 14. More importantly, the time when the drawer inner pot 1 moves forward under the action of inertia and overcomes the pre-tightening force of the coil spring 12 is later than the time when the gravity hammer 33 is switched to the blocking state. In this way, the gravity hammer 33 can timely block the drawer inner pot 1 when the vehicle decelerates, prevent the drawer inner pot 1 from opening automatically, and the structure design is ingenious.

[0075] The technical scheme provided by the embodiments of the present disclosure has at least the following beneficial effects:

[0076] 1. The vehicle-mounted drawer structure of the present disclosure is provided with a labyrinth groove 14 and a labyrinth lock core 34 matched with each other between the drawer inner pot 1 and the drawer chassis 3, so that the drawer inner pot 1 needs to move forward first and then backward to be normally opened; the drawer inner pot 1 has a tendency to open backward under the inertial effect of the acceleration of the car, but the labyrinth lock core 34 hooks the drawer inner pot 1 through the groove wall of the labyrinth groove 14, so that the drawer inner pot 1 cannot move backward relative to the drawer chassis 3, which can ensure that the drawer inner pot 1 does not pop open under the inertial effect of the acceleration of the car; the vehicle-mounted drawer structure of the present disclosure is also provided with a gravity hammer 33, and the protruding part 334 of the gravity hammer 33 is located outside the drawer inner pot 1 when the drawer inner pot 1 is in the closed state; under the deceleration of the car, the gravity hammer 33 swings forward under the inertial effect, the protruding part 334 rotates to the front end of the drawer inner pot 1, and the drawer inner pot 1 is blocked from moving forward, effectively preventing the labyrinth lock core 34 from being detached from the labyrinth groove 14 under the inertial effect of the deceleration of the car. Therefore, the labyrinth groove 14, the labyrinth lock core 34 and the gravity hammer 33 can effectively solve the problem of automatic pop-up of the drawer under the inertial effect of the acceleration and deceleration of the car, the structure design is ingenious, and the user experience is good.

[0077] 2. The vehicle-mounted drawer structure of the present disclosure is provided with a coil spring 12, and the coil spring 12 is in a tension state when the drawer inner pot 1 is in a closed state, providing a pre-tightening force for the drawer inner pot 1, so that the drawer inner pot 1 has a forward displacement unlocking stroke space (required to unlock the labyrinth lock), but the drawer inner pot 1 will not shake relative to the drawer chassis 3 in the closed state, improving the stability of the vehicle-mounted drawer structure; at the same time, the coil spring 12 can also make the drawer inner pot 1 need to overcome the pre-tightening force of the coil spring 12 before moving forward under the inertial effect when the car is in the deceleration condition, so that the forward movement of the drawer inner pot 1 always occurs after the gravity hammer 33 swings forward, laying a foundation for avoiding the drawer inner pot 1 from popping open when decelerating.

[0078] 3. The vehicle-mounted drawer structure of the present disclosure is provided with a gravity hammer 33, which is in an initial state under the action of a torsion spring 335 when the vehicle is stationary, uniform or accelerating, and does not swing; the front end of the drawer inner pot 1 is provided with two fixed blocks 16, one of which is used to abut against the raised portion 334 after rotation, the bottom surface of the fixed block 16 is higher than the top surface of the rotating portion 331 and the gravity portion 332, and lower than the raised portion 334, so that in the case of normally opening the drawer inner pot 1, the fixed block 16 at the front end of the drawer inner pot 1 can pass above the rotating portion 331 and the gravity portion 332, and at this time, the fixed block 16 is not blocked; when the deceleration of the vehicle 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, the raised portion 334 abuts against the fixed block 16 after rotation, blocks the forward movement of the drawer inner pot 1, and makes the mandrel 341 unable to separate from the labyrinth groove 14; more importantly, the moment when the drawer inner pot 1 moves forward under the action of inertia to overcome the pre-tightening force of the coil spring 12 is later than the moment when the gravity hammer 33 swings into place, that is, the gravity hammer 33 can timely block the drawer inner pot 1 when decelerating, preventing the drawer inner pot 1 from automatically opening under the condition of deceleration, and the structure design is ingenious.
