Description

Technical Field

[0001] The utility model belongs to the technical field of vehicles, and more specifically, it relates to a buffer clamping mechanism, an in-vehicle cup holder and a vehicle. Background Technique

[0002] The in-vehicle cup holder is usually located on the instrument panel, the center console or the rear seat, and is a product for providing a place to place and clamp cups for drivers and passengers. The cup holder is composed of a cavity for placing the cup, a cup clip for clamping the cup, a lifting cup holder, a cover plate that can move up and down, a rubber pad for preventing bumps and abnormal noises, etc. Among them, the cup clip has the function of clamping the cup, which can fix the cup after different-sized cups are placed in the cup holder to prevent it from shaking randomly. Therefore, the cup clip plays a very important role in the use of the cup holder.

[0003] With the development of the automotive industry, various functional cup holders have continuously emerged in the market. From open cup holders to hidden cup holders with lids, and now to lifting cup holders and temperature-controlled cup holders, the functions and practicality of cup holders are getting higher and higher, and customers' attention to cup holders is also getting higher and higher. The requirements for the quality, performance and functions of cup holders are becoming more and more strict.

[0004] At present, the cup clips on the market use springs to achieve the free expansion and contraction of the cup clips. When the cup clip pops out instantaneously under the action of the spring, the cup clip will make abnormal noises when colliding with the cup. In addition, when the cup clip returns instantaneously under the action of the spring, there is also a problem that the cup clip collides with the initial position and generates abnormal noises. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a buffer clamping mechanism, aiming to solve the problem of abnormal noises caused by the collision of the cup clip when it pops out or returns instantaneously.

[0006] To achieve the above purpose, the technical scheme adopted by the utility model is: to provide a buffer clamping mechanism, including:

[0007] A cup holder assembly, the cup holder assembly includes a driving disc, a fixed disc and a cup holder body arranged coaxially. The driving disc is axially rotatably arranged. The cup holder body longitudinally penetrates the fixed disc. A plurality of avoidance through holes are formed in the circumferential direction of the cup holder body, and all the plurality of avoidance through holes are located above the fixed disc;

[0008] A plurality of clamping components, and the plurality of clamping components correspond to the plurality of avoidance through holes one by one. The clamping component includes a cup clip, an elastic member, and a damping member. The first end of the cup clip is hinged to the upper end surface of the fixed disk, and the second end of the cup clip is slidably disposed on the driving disk. The cup clip has a clamping portion corresponding to the avoidance through hole. The elastic member is connected between the fixed disk and the cup clip, and the elastic member is used to provide an elastic force for the clamping portion to move towards the avoidance through hole. The damping member is disposed on the fixed disk, and the damping member cooperates with the second end of the cup clip and provides a rotational damping force.

[0009] In a possible implementation manner, the damping member includes:

[0010] A mating gear, and the mating gear is fixedly disposed on the lower end surface of the second end of the cup clip;

[0011] A damping gear, and the damping gear is rotatably disposed on the upper end surface of the fixed disk. The damping gear meshes with the mating gear and provides a rotational damping force, so that the clamping portion of the cup clip will not pop out or return instantaneously, and the problem of abnormal noise generated by the cup clip due to collision can be avoided.

[0012] In a possible implementation manner, a plurality of mounting holes are provided in the circumferential direction of the fixed disk, and the plurality of mounting holes correspond to the plurality of damping members one by one. A damping block is clamped in the mounting hole, and the damping gear is rotatably disposed on the upper end surface of the damping block. The damping block is used to provide the rotational damping force of the damping gear, and the stability of the damping block in the mounting hole can be ensured.

[0013] In a possible implementation manner, a plurality of sliding grooves are formed in the circumferential direction of the driving disk, and sliding rods are disposed on the lower end surface of the second end of the cup clip. The plurality of sliding rods are slidably disposed in the sliding grooves one by one, so as to avoid the situation that the cup clip is stuck when rotating with the driving disk.

[0014] In a possible implementation manner, the sliding groove is inclined, and the sliding groove is arranged from the outside to the inside along the rotation locking direction of the driving disk, so as to avoid the situation that the cup clip is stuck when rotating with the driving disk.

[0015] In a possible implementation manner, the clamping portion is located between the first end and the second end and extends towards the corresponding avoidance through hole. The side of the clamping portion close to the first end has an inner concave arc, and the side of the clamping portion close to the second end has an outer convex arc, which can ensure that the clamping portion of the cup clip can be smoothly rotated into or out of the avoidance through hole, and avoid the interference between the clamping portion of the cup clip and the avoidance through hole.

[0016] In a possible implementation, the width of the clamping portion increases gradually from close to the avoidance through hole to away from the avoidance through hole, so that it can enter or leave the avoidance through hole more smoothly and reduce jamming.

[0017] In a possible implementation, the elastic member is a torsion spring, one end of which is connected to the fixed disk, and the other end of which is connected to the cup clip, and the torsion spring is used to provide elastic force for the clamping portion to move toward the avoidance through hole, so that the clamping portion of the cup clip is pressed against the outer periphery of the cup to ensure the stability of the cup.

[0018] The beneficial effect of a buffer clamping mechanism provided by the utility model is that: compared with the prior art, the buffer clamping mechanism includes a driving disc, a fixed disc, a cup holder body and a plurality of clamping components, and the clamping components include a cup clip, an elastic member and a damping member. When a cup needs to be placed in the cup holder body, the driving disc rotates clockwise, and the driving disc drives the second ends of the plurality of cup clips to move clockwise, and the cup clips use the first end as a rotation axis to rotate the clamping parts in a direction away from the corresponding avoidance through hole. As the driving disc rotates continuously clockwise, the clamping parts of the plurality of cup clips rotate outward from the avoidance through hole. At this time, the clamping space formed by the plurality of clamping parts in the cup holder body gradually increases, and the cup can be inserted into the cup holder body from top to bottom. When it is necessary to lock the cup in the cup holder body, the driving disc rotates counterclockwise, and the driving disc drives the second ends of the multiple cup clips to move counterclockwise. The cup clip uses the first end as the rotation axis to rotate the clamping part in the direction close to the corresponding avoidance through hole. As the driving disc continues to rotate counterclockwise, the clamping parts of the multiple cup clips are screwed inward from the avoidance through hole until the multiple clamping parts are respectively against the outer periphery of the cup. The elastic member applies elastic force to the clamping part, so that the multiple clamping parts are respectively pressed against the outer periphery of the cup, and the cup remains stable. When it is necessary to take out the cup, just rotate the driving disc clockwise, which will not be repeated here. Regardless of whether the cup clip locks or releases the cup, the damping member will form a rotation damping on the second end of the cup clip to prevent the cup clip from popping out or returning instantly, and the cup clip from colliding instantly and causing abnormal noise.

[0019] The utility model also provides a vehicle-mounted cup holder, comprising the buffer clamping mechanism and a cup holder cover plate, wherein the cup holder cover plate is lifted and lowered for the driving disc to rotate clockwise or counterclockwise.

[0020] The beneficial effects of a vehicle cup holder provided by the present utility model are as follows: Compared with the prior art, when the cup holder cover plate rises, it drives the driving disc to rotate clockwise, and the clamping parts of multiple cup clamps loosen the cup. After the cup rises to the top, it can be easily taken out; when the cup holder cover plate descends, it drives the driving disc to rotate counterclockwise, and the clamping parts of multiple cup clamps clamp the cup, and the cup descends to the bottom and is in a locked state. Whether the cup clamp locks or loosens the cup, the damping member will form a rotational damping on the second end of the cup clamp, avoiding the problem of abnormal noise caused by the cup clamp popping out or returning instantaneously and colliding instantaneously.

[0021] The present utility model also provides a vehicle, including the vehicle cup holder.

[0022] The beneficial effects of a vehicle provided by the present utility model are as follows: Compared with the prior art, since the above-mentioned vehicle cup holder is used in this vehicle, it has the same beneficial effects as the vehicle cup holder, which will not be elaborated here.

[0039] Please refer to Figures 1 to 5 , and now a buffer clamping mechanism provided by the present utility model will be described. A buffer clamping mechanism includes a cup holder assembly and a plurality of clamping assemblies.

[0040] The cup holder assembly includes a driving disc 100, a fixed disc 200 and a cup holder body 300 arranged coaxially. The driving disc 100 is axially rotatably arranged. The cup holder body 300 longitudinally penetrates the fixed disc 200. A plurality of avoidance through holes 310 are circumferentially formed in the cup holder body 300, and the plurality of avoidance through holes 310 are all located above the fixed disc 200;

[0041] A plurality of clamping assemblies correspond to a plurality of avoidance through holes 310 one by one. The clamping assembly includes a cup clamp 400, an elastic member 500, and a damping member 600. The first end 410 of the cup clamp 400 is hinged to the upper end surface of the fixed disc 200, and the second end 420 of the cup clamp 400 is slidably disposed on the driving disc 100. The cup clamp 400 has a clamping portion 430 corresponding to the avoidance through hole 310. The elastic member 500 is connected between the fixed disc 200 and the cup clamp 400, and the elastic member 500 is used to provide an elastic force for the clamping portion 430 to move towards the avoidance through hole 310. The damping member 600 is disposed on the fixed disc 200, and the damping member 600 cooperates with the second end 420 of the cup clamp 400 and provides rotational damping.

[0042] A buffer clamping mechanism provided by the present utility model, compared with the prior art, the buffer clamping mechanism includes a driving disc 100, a fixed disc 200, a cup holder body 300, and a plurality of clamping assemblies. The clamping assembly includes a cup clamp 400, an elastic member 500, and a damping member 600. When it is necessary to place a cup in the cup holder body 300, the driving disc 100 rotates clockwise, and the driving disc 100 drives the second ends 420 of the plurality of cup clamps 400 to move clockwise. The cup clamp 400 rotates with the first end 410 as the rotation axis, so that the clamping portion 430 rotates away from the corresponding avoidance through hole 310. As the driving disc 100 continuously rotates clockwise, the clamping portions 430 of the plurality of cup clamps 400 are screwed outwards from the avoidance through holes 310. At this time, the clamping space formed by the plurality of clamping portions 430 in the cup holder body 300 gradually increases, and the cup can be inserted into the cup holder body 300 from top to bottom. When it is necessary to lock the cup in the cup holder body 300, the driving disc 100 rotates counterclockwise, and the driving disc 100 drives the second ends 420 of the plurality of cup clamps 400 to move counterclockwise. The cup clamp 400 rotates with the first end 410 as the rotation axis, so that the clamping portion 430 rotates towards the corresponding avoidance through hole 310. As the driving disc 100 continuously rotates counterclockwise, the clamping portions 430 of the plurality of cup clamps 400 are screwed inwards from the avoidance through holes 310 until the plurality of clamping portions 430 respectively abut against the outer periphery of the cup. The elastic member 500 applies an elastic force to the clamping portion 430, so that the plurality of clamping portions 430 respectively press tightly against the outer periphery of the cup, and the cup is kept stable. When it is necessary to take out the cup, just rotate the driving disc 100 clockwise, which will not be elaborated here. Whether the cup clamp 400 locks or loosens the cup, the damping member 600 will form rotational damping on the second end 420 of the cup clamp 400, avoiding the problem of instant pop-up or instant return of the cup clamp 400 and instant collision of the cup clamp 400 resulting in abnormal noise.

[0043] It should be noted that: the cup holder body 300 is a cylindrical structure, its bottom has a closed bottom plate, and its top has an open end. The clockwise rotation direction of the driving disc 100 is defined as the rotation loosening direction, and the counterclockwise rotation direction of the driving disc 100 is defined as the rotation locking direction.

[0044] Please refer to Figure 5 , when the driving disc 100 rotates counterclockwise in sequence, the buffer clamping mechanism forms three state diagrams of state a, state b, and state c respectively. In state a, the clamping portion 430 of the cup holder 400 does not enter the interior of the cup holder body 300. In state b, a small part of the structure of the clamping portion 430 of the cup holder 400 enters the interior of the cup holder body 300. In state c, most of the structure of the clamping portion 430 of the cup holder 400 enters the interior of the cup holder body 300. By the sequential counterclockwise rotation of the driving disc 100, the clamping portions 430 of multiple cup holders 400 gradually enter the interior of the cup holder body 300, and the gradual clamping of the cup can be achieved. Similarly, when the driving disc 100 rotates clockwise, the clamping portions 430 of multiple cup holders 400 gradually leave the interior of the cup holder body 300, and the gradual loosening of the cup can be achieved, which will not be elaborated here.

[0045] Please refer to Figure 2 and Figure 3 , the damping member 600 includes a mating gear 610 and a damping gear 620. The mating gear 610 is fixedly disposed on the lower end surface of the second end 420 of the cup holder 400. The damping gear 620 is rotatably disposed on the upper end surface of the fixed disc 200, and the damping gear 620 meshes with the mating gear 610 and provides rotational damping.

[0046] Among them, the lower end surface of the second end 420 of the cup holder 400 is provided with a rotating shaft. The mating gear 610 is sleeved and fixed on the rotating shaft. The damping gear 620 is located on the upper end surface of the fixed disc 200, and the damping gear 620 meshes with the mating gear 610. When the mating gear 610 rotates with the second end 420 of the cup holder 400, the damping gear 620 forms damping on the mating gear 610 meshing with it, so that whether the cup holder 400 rotates counterclockwise or clockwise, a resistance f as shown in the appendix Figure 1 will be formed, and the clamping portion 430 of the cup holder 400 will not pop out or return instantaneously, which can avoid the problem of abnormal noise generated by the cup holder 400 due to collision.

[0047] Please refer to Figure 1 and Figure 4 , a plurality of mounting holes are provided in the circumferential direction of the fixed disc 200. The plurality of mounting holes correspond to the plurality of damping members 600 one by one. A damping block 630 is clamped in the mounting hole. The damping gear 620 is rotatably disposed on the upper end surface of the damping block 630, and the damping block 630 is used to provide rotational damping for the damping gear 620.

[0048] Specifically, the shapes of the damping block 630 and the mounting hole are mutually adapted. At the same time, card slots are respectively provided on both sides of the mounting hole, and corresponding clamping elastic pieces are respectively provided on both sides of the damping block 630. The damping block 630 is embedded in the mounting hole, and the clamping elastic pieces on both sides of the damping block 630 are correspondingly clamped in the card slots on both sides of the mounting hole. The clamping elastic pieces deform outward and are clamped in the corresponding card slots, which can ensure the stability of the damping block 630 in the mounting hole.

[0049] Among them, a damping shaft is longitudinally penetrated on the damping block 630. The upper end of the damping shaft penetrates into the upper end surface of the damping block 630 and the above-mentioned damping gear 620 is installed. The part of the damping shaft located inside the damping block 630 can form damping through a mechanical structure or the direction of damping liquid, so that the damping gear 620 forms a rotating gear during rotation, and then forms a rotational damping on the cup holder 400.

[0050] Please refer to Figure 1 , a plurality of sliding grooves 110 are circumferentially formed on the driving disc 100, and a sliding rod 460 is arranged on the lower end surface of the second end 420 of the cup holder 400. A plurality of sliding rods 460 are correspondingly and slidably arranged in the sliding grooves 110.

[0051] Among them, when the driving disc 100 rotates, the sliding rod 460 slides in the corresponding sliding groove 110, and the second end 420 of the cup holder 400 rotates with the driving disc 100, which can compensate for the position change of the first end 410 of the cup holder 400 on the fixed disc 200 and the position change of the second end 420 of the cup holder 400 on the driving disc 100, and avoid the situation that the cup holder 400 is stuck when rotating with the driving disc 100.

[0052] Specifically, the sliding groove 110 is inclined, and the sliding groove 110 is arranged from the outside to the inside along the rotation locking direction of the driving disc 100, which can effectively compensate for the position change of the second end 420 of the cup holder 400 when the cup holder 400 rotates with the driving disc 100, and avoid the situation that the cup holder 400 is stuck when rotating with the driving disc 100. The inclination angle of the sliding groove 110 is determined by the structure of the cup holder 400 itself and the positional relationship between the first end 410 and the second end 420 of the cup holder 400, and will not be elaborated here.

[0053] Please refer to Figure 1 and Figure 3, the clamping portion 430 is located between the first end 410 and the second end 420 and extends towards the corresponding avoidance through hole 310. The side of the clamping portion 430 close to the first end 410 has an inner concave arc 440, and the side of the clamping portion 430 close to the second end 420 has an outer convex arc 450. When the clamping portion 430 rotates into or out of the avoidance through hole 310, the inner concave arc 440 can avoid one end of the avoidance through hole 310 with the rotation of the cup clip 400, and the outer convex arc 450 can avoid the other end of the avoidance through hole 310 with the rotation of the cup clip 400. The existence of the inner concave arc 440 and the outer convex arc 450 can ensure that the clamping portion 430 of the cup clip 400 smoothly rotates into or out of the avoidance through hole 310, and avoid the interference between the clamping portion 430 of the cup clip 400 and the avoidance through hole 310.

[0054] Specifically, the width of the clamping portion 430 increases from the side close to the avoidance through hole 310 to the side away from the avoidance through hole 310. The clamping portion 430 is of a trapezoidal structure with a smaller width at the end, which can enter or leave the avoidance through hole 310 more smoothly and reduce jamming.

[0055] Specifically, the elastic member 500 is a torsion spring. One end of the torsion spring is connected to the fixed disc 200, and the other end of the torsion spring is connected to the cup clip 400. The torsion spring is used to provide the elastic force for the clamping portion 430 to move towards the avoidance through hole 310.

[0056] Specifically, fixing sleeves are integrally formed on the upper end surface of the fixed disc 200 and the lower end surface of the cup clip 400. The two ends of the torsion spring are respectively inserted into the corresponding fixing sleeves, so as to form the elastic force for the clamping portion 430 of the cup clip 400 to rotate into the avoidance through hole 310. The torsion spring forms an elastic force F as shown in the appendix Figure 1 . After the cup clip 400 is adjusted in place, the torsion spring provides an elastic force F to the cup clip 400, so that the clamping portion 430 of the cup clip 400 presses against the outer circumference of the cup to ensure the stability of the cup.

[0057] Based on the same inventive concept, the present utility model also provides a vehicle cup holder, which includes the above-mentioned buffer clamping mechanism and a cup holder cover plate. The cup holder cover plate is lifted and lowered to drive the disc 100 to rotate clockwise or counterclockwise.

[0058] A vehicle cup holder provided by the present utility model, compared with the prior art, when the cup holder cover plate rises, it drives the driving disc 100 to rotate clockwise, and the clamping parts 430 of multiple cup clips 400 release the cup. After the cup rises to the top, it can be easily taken out; when the cup holder cover plate descends, it drives the driving disc 100 to rotate counterclockwise, and the clamping parts 430 of multiple cup clips 400 clamp the cup, and the cup descends to the bottom and is in a locked state. Whether the cup clip 400 locks or releases the cup, the damping member 600 will form a rotational damping on the second end 420 of the cup clip 400, avoiding the problem that the cup clip 400 pops out or returns instantaneously and makes abnormal noises due to instant collision of the cup clip 400.

[0059] Based on the same inventive concept, the present utility model also provides a vehicle, and the vehicle includes the above vehicle cup holder.

[0060] A vehicle provided by the present utility model, compared with the prior art, since the vehicle uses the above vehicle cup holder, it has the same beneficial effects as the vehicle cup holder, which will not be elaborated here.

[0061] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
