Description

Technical Field

[0001] The present invention belongs to the technical field of vehicle parts, and relates to a pull-out and foldable vehicle cup holder and a vehicle. Background Art

[0002] A pull-out cup holder is a pull-out storage device installed inside an automobile for placing cups. The design of the pull-out cup holder is similar to a drawer and is usually hidden in positions such as the center console, the armrest box, or the side of the seat.

[0003] Existing pull-out cup holders generally include an outer jacket, a sliding seat, and a liftable cup holder. During the process of the sliding seat being pulled out from the outer jacket, the cup holder remains in a lowered state in the front section of the sliding seat's travel. When the cup holder extends out of the opening of the outer jacket, as the sliding seat continues to slide outwards, the cup holder automatically rises and unfolds; during the process of the sliding seat being pushed back into the outer jacket from the fully extended position, the cup holder automatically descends. When the cup holder is about to cross the opening of the outer jacket, the cup holder descends to the lowest position and remains in the lowered state without moving during the subsequent travel.

[0004] In order to achieve the above effects, the existing cup holder structure is designed very complexly. There is no linkage relationship established between the lifting movement of the cup holder and the sliding travel of the sliding seat. The cup holder cannot choose to be linked or not linked according to the travel position of the sliding seat, and the cup holder is not smooth enough during use and there is a situation of jamming. Summary of the Invention

[0005] The purpose of the present invention is to address the above problems existing in the prior art, and propose a pull-out and foldable vehicle cup holder and a vehicle.

[0006] The purpose of the present invention can be achieved by the following technical solutions: A pull-out and foldable vehicle cup holder, comprising:

[0007] An outer jacket;

[0008] A sliding seat, the sliding seat is slidably connected to the outer jacket, and at least one folding mechanism is installed on the sliding seat;

[0010] A cup holder base, the cup holder base is liftably connected to the sliding seat through the folding mechanism, and the height position of the cup holder base on the sliding seat is determined by the geometric state of the folding mechanism;

[0011] Linkage element, the linkage element is slidably mounted on the sliding seat, the number of the linkage elements is the same as the number of the folding mechanisms and they are arranged in one-to-one correspondence, the linkage element is linked to the folding mechanism, when the linkage element moves relative to the sliding seat, it drives the folding mechanism to move, and the stroke position of the linkage element on the sliding seat determines the geometric state of the folding mechanism;

[0012] The linkage element has a first connection state and a second connection state; when the linkage element is in the first connection state, the linkage element is locked with the outer jacket, and the linkage element and the sliding seat are allowed to move relative to each other; when the linkage element is in the second connection state, the linkage element and the outer jacket are allowed to move relative to each other, and the linkage element is locked with the sliding seat;

[0013] The movement direction of the sliding seat within the switching interval determines whether the linkage element tends to the first connection state or the second connection state;

[0014] When the sliding seat is located in the linkage interval, the linkage element is in the first connection state, and the sliding seat is linked to the folding mechanism through the linkage element;

[0015] When the sliding seat is located in the idle stroke interval, the linkage element is in the second connection state, and the sliding seat is not linked to the folding mechanism.

[0016] Preferably, a drive shaft and a sliding shaft are installed on the linkage element, the drive shaft is connected to the folding mechanism, a first chute is provided on the outer jacket, a second chute is provided on the sliding seat, and the sliding shaft passes through the first chute and the second chute;

[0017] When the sliding seat is located in the linkage interval, the sliding shaft is locked with the first chute, causing the linkage element to remain stationary relative to the outer jacket; when the sliding seat is located in the idle stroke interval, the sliding shaft is locked with the second chute, causing the linkage element to remain stationary relative to the sliding seat.

[0018] Preferably, the first chute includes a first straight section and a first inclined chute section, the first inclined chute section is connected to one end of the first straight section, the second chute includes a second straight section and a second inclined chute section, and the second inclined chute section is connected to one end of the second straight section;

[0019] When the linkage element is in the first connection state, the sliding shaft is located at the end of the first inclined chute section and the second straight section, and the end of the first inclined chute section restricts the movement of the linkage element relative to the outer jacket by abutting against the sliding shaft, and the sliding shaft is allowed to move within the second straight section;

[0020] When the sliding seat is in the switching interval, the sliding shaft is located in the first inclined groove section and the second inclined groove section, and the sliding direction of the sliding seat determines whether the sliding shaft tends to the end of the first inclined groove section or the end of the second inclined groove section;

[0021] When the linkage element is in the second connection state, the sliding shaft is located at the end of the first straight section and the second inclined groove section. The end of the second inclined groove section restricts the movement of the linkage element relative to the sliding seat by abutting against the sliding shaft, and the sliding shaft is allowed to move within the first straight section.

[0022] Preferably, both the first straight section and the second straight section are arranged along the sliding direction of the sliding seat. The first straight section and the second straight section are parallel and do not coincide. Both the first inclined groove section and the second inclined groove section are inclined with respect to the sliding direction of the sliding seat. The first inclined groove section inclines towards the second straight section, and the end of the first inclined groove section and the second straight section are on the same straight line. The second inclined groove section inclines towards the first straight section, and the end of the second inclined groove section and the first straight section are on the same straight line.

[0023] Preferably, the number of both the folding mechanism and the linkage element is two. The two linkage elements are respectively located on both sides of the sliding seat. The two side walls of the sliding seat are close to the two side walls of the outer jacket. The first sliding grooves are arranged on both side walls of the outer jacket, and the second sliding grooves are arranged on both side walls of the sliding seat.

[0024] Preferably, the sliding seat is provided with two limiting members, which are respectively close to the two side walls of the sliding seat. A limiting gap is reserved between the limiting member and the side wall of the sliding seat. The linkage element is arranged in the limiting gap, and the front and back surfaces of the linkage element are respectively abutted against the side wall of the sliding seat and the limiting member.

[0025] Preferably, the folding mechanism is arranged as a scissor structure. The folding mechanism includes a first folding arm, a second folding arm and a hinge shaft. The first folding arm and the second folding arm are hinged by the hinge shaft. One end of the first folding arm is hinged to the cup holder seat. The driving shaft is rotatably connected to the other end of the first folding arm. The other end of the first folding arm is slidably connected to the sliding seat through the driving shaft. One end of the second folding arm is slidably connected to the cup holder seat, and the other end of the second folding arm is hinged to the sliding seat.

[0026] Preferably, it further includes a spring winding, the spring winding is installed on the sliding seat, and the spring winding is connected to the outer jacket. The spring winding always applies a movement tendency to the sliding seat to make it extend and slide.

[0027] Preferably, it further includes a motor. The motor is installed on the sliding seat. A gear is provided on the rotating shaft of the motor, and a rack is provided on the outer jacket. The gear meshes with the rack, and the motor can drive the sliding seat to slide through forward and reverse rotations.

[0028] A vehicle includes the pull-out and foldable vehicle cup holder described above.

[0029] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0030] 1. The movement of the sliding seat in the linkage interval can drive the cup holder base to rise and fall through the folding mechanism, while the movement in the idle stroke interval will not cause the cup holder base to rise and fall; thus, the sliding seat drives the cup holder base to rise at the end of the extension stroke; drives the cup holder base to fall at the front stage of the retraction stroke, and when the cup holder base enters the outer jacket, the sliding seat is not linked with the folding mechanism.

[0031] 2. The linkage element is the core component for adjusting the height of the cup holder base. The linkage element has two different connection states; only when the sliding seat is in the linkage interval, the linkage element is in the first connection state. At this time, the linkage element locks the outer jacket and allows relative sliding with the sliding seat. Therefore, when the sliding seat slides, relative movement can be generated between the folding mechanism and the linkage element, thereby driving the cup holder base to rise and fall; only when the sliding seat is in the idle stroke interval, the linkage element is in the second connection state. At this time, the linkage element locks the sliding seat and allows relative sliding with the outer jacket. Therefore, when the sliding seat slides, the folding mechanism and the linkage element remain stationary, and the cup holder base remains at the lowest position without movement.

[0032] 3. The drive shaft and the folding mechanism are hinged together, which enables the sliding shaft to swing around the drive shaft, so that the sliding shaft can switch to the first straight line segment or the second straight line segment. When the sliding shaft is located in the first inclined groove segment or the second inclined groove segment, it can be locked together with the outer jacket or the sliding seat.

[0033] 4. Since both the first straight line segment and the second straight line segment are arranged along the sliding direction of the sliding seat, this means that when the sliding seat slides, the sliding shaft can slide along the straight line segment; while there is an angular deviation between the inclined groove segment and the sliding direction of the sliding seat, which means that the inclined groove segment can lock the sliding shaft, thereby restricting the sliding of the linkage element.

[0034] 5. By respectively arranging a folding mechanism and a linkage element on both sides of the sliding seat, the balance and stability of the entire structure during operation can be ensured. This design can effectively avoid tilting or jamming caused by unilateral force, making the cup holder more stable and safe. Moreover, the two linkage elements work together to synchronously drive the two folding mechanisms to move, ensuring the consistency of the movement of the cup holder seat during the lifting process.

Detailed implementation mode

[0047] The following are specific embodiments of the present invention and in combination with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0048] As Figures 1 to 5 shown, a pull-out folding vehicle cup holder includes:

[0049] The outer rack 100;

[0050] The sliding seat 200, the sliding seat 200 is slidably connected to the outer rack 100, and at least one folding mechanism 300 is installed on the sliding seat 200;

[0051] The stroke positions of the sliding seat 200 include an unfolded position, a first switching position, a second switching position, and a storage position arranged in sequence along the retraction direction; a linkage interval is formed between the unfolded position and the first switching position, a switching interval is formed between the first switching position and the second switching position, and a free stroke interval is formed between the second switching position and the storage position;

[0052] The cup holder seat 400, the cup holder seat 400 is liftably connected to the sliding seat 200 through the folding mechanism 300, and the height position of the cup holder seat 400 on the sliding seat 200 is determined by the geometric state of the folding mechanism 300;

[0053] The linkage element 500, the linkage element 500 is slidably installed on the sliding seat 200, the number of the linkage elements 500 is the same as the number of the folding mechanisms 300 and they are arranged in one-to-one correspondence, the linkage element 500 is linked to the folding mechanism 300, when the linkage element 500 moves relative to the sliding seat 200, it drives the folding mechanism 300 to move, and the stroke position of the linkage element 500 on the sliding seat 200 determines the geometric state of the folding mechanism 300;

[0054] The linkage element 500 has a first connection state and a second connection state; when the linkage element 500 is in the first connection state, the linkage element 500 is locked to the outer rack 100, and the linkage element 500 and the sliding seat 200 are allowed to move relative to each other; when the linkage element 500 is in the second connection state, the linkage element 500 and the outer rack 100 are allowed to move relative to each other, and the linkage element 500 is locked to the sliding seat 200;

[0055] The movement direction of the sliding seat 200 within the switching range determines whether the linkage element 500 tends to select the first connection state or the second connection state;

[0056] When the sliding seat 200 is located in the linkage range, the linkage element 500 is in the first connection state, and the sliding seat 200 is linked to the folding mechanism 300 through the linkage element 500;

[0057] When the sliding seat 200 is located in the idle stroke range, the linkage element 500 is in the second connection state, and the sliding seat 200 is not linked to the folding mechanism 300.

[0058] It should be added that the outer jacket 100 is designed as a box-shaped structure with a front opening. The process of the sliding seat 200 sliding into the interior of the outer jacket 100 is defined as retraction, and the movement of extending out of the front opening is defined as extension. The folding mechanism 300 can drive the cup holder seat 400 to rise and fall, thereby adjusting the height position of the cup holder seat 400 relative to the sliding seat 200 (which can also be regarded as the distance between the two). The cup holder seat 400 is provided with at least one round hole, and containers such as cups can be placed into the round hole, and the bottom of the cups and other containers is placed on the sliding seat 200. The sliding seat 200 and the cup holder seat 400 cooperate to achieve the cup holder function.

[0059] When the sliding seat 200 is located in the linkage range, the folding mechanism 300 and the cup holder seat 400 are located outside the outer jacket 100; when the sliding seat 200 is located in the switching range and the idle stroke range, part or the whole of the folding mechanism 300 and the cup holder seat 400 are located inside the outer jacket 100. The sliding seat 200 can only control the movement of the folding mechanism 300 within the linkage range, thereby controlling the rise and fall of the cup holder seat 400. Once the sliding seat 200 slides into the switching range or the idle stroke range, the folding mechanism 300 always remains stationary, and the cup holder seat 400 remains in the lowered state close to the sliding seat 200 (that is, the cup holder seat 400 is located at the lowest position). At this time, no matter how the sliding seat 200 slides, it cannot drive the folding mechanism 300 to move.

[0060] In the example, when the sliding seat 200 is in the linkage range, the folding mechanism 300 and the cup holder seat 400 are always located outside the outer jacket 100; and when the sliding seat 200 is in the unfolded position, the cup holder seat 400 is at the highest position, and a cup can be placed at this time; when the sliding seat 200 is in other stroke ranges, the cup holder seat 400 remains at the lowest position and is located inside the outer jacket 100. This means that the sliding seat 200 can slide arbitrarily without worrying about the folding mechanism 300, the cup holder seat 400 colliding or rubbing against the outer jacket 100.

[0061] The linkage element 500 is a core component for adjusting the height of the cup holder 400, and the linkage element 500 has two different connection states; only when the sliding seat 200 is in the linkage interval, the linkage element 500 is in the first connection state, at which time the linkage element 500 locks the outer coat rack 100 and allows relative sliding with the sliding seat 200, so when the sliding seat 200 slides, relative movement can be generated between the folding mechanism 300 and the linkage element 500, thereby driving the cup holder 400 to rise and fall; only when the sliding seat 200 is in the idle stroke interval, the linkage element 500 is in the second connection state, at which time the linkage element 500 locks the sliding seat 200 and allows relative sliding with the outer coat rack 100, so when the sliding seat 200 slides, the folding mechanism 300 and the linkage element 500 remain stationary, and the cup holder 400 remains in the lowest position without moving.

[0062] The logic of switching the connection state of the linkage element 500 is: when the sliding seat 200 moves to the extended position in the switching interval, the linkage element 500 gradually tends to the first connection state; when the sliding seat 200 moves to the stored position in the switching interval, the linkage element 500 gradually tends to the second connection state.

[0063] The process of the sliding seat 200 being pushed outward: it moves from the storage position to the unfolding direction, the sliding seat 200 first moves in the empty stroke interval, at this time the linkage element 500 is in the second connection state, the linkage element 500 and the sliding seat 200 remain stationary, the cup holder seat 400 remains in the lowest position, at this time the cup holder seat 400 can move with the sliding seat 200 inside the outer coat rack 100 without causing collision or interference; as the sliding seat 200 continues to move, it enters the switching interval, and the linkage element 500 gradually changes from the second connection state to the first connection state; the sliding seat 200 enters the linkage interval, at this time the linkage element 500 is in the first connection state, it is locked with the outer coat rack 100, the sliding seat 200 continues to move forward, and the folding mechanism 300 is driven to move through the linkage element 500, thereby causing the cup holder seat 400 to rise.

[0064] The process of the sliding seat 200 being pushed back to the coat rack 100: the sliding seat 200 moves from the unfolded position to the storage direction, the sliding seat 200 first passes through the linkage interval, the linkage element 500 is still in the first connection state, the sliding seat 200 drives the cup holder seat 400 to descend through the linkage element 500 and the folding mechanism 300, when the sliding seat 200 is in the first switching position, the cup holder seat 400 is just in the lowest position and can smoothly enter the front opening of the coat rack 100; then the sliding seat 200 enters the switching interval, because it is pushed inward, the linkage element 500 gradually switches to the second connection state, the sliding seat 200 enters the empty stroke interval, the linkage element 500 is locked with the sliding seat 200, so that the sliding seat 200 and the folding mechanism 300 are released from the linkage relationship, and the movement of the sliding seat 200 does not drive the cup holder seat 400 to rise or fall.

[0065] In summary, the movement of the sliding seat 200 in the linkage interval can drive the lifting of the cup holder seat 400, while the movement in the idle stroke interval will not cause the movement of the cup holder seat 400; therefore, when the sliding seat 200 is in the initial stage of retraction, the cup holder seat 400 descends. When the sliding seat 200 retracts to a certain position, the linkage element 500 is locked with the sliding seat 200. As the sliding seat 200 continues to slide, the cup holder seat 400 remains stationary. In the initial stage of the extension of the sliding seat 200, the cup holder seat 400 remains stationary. When the sliding seat 200 extends to a certain position, the linkage element 500 is separated from the sliding seat 200. As the sliding seat 200 continues to slide, the cup holder seat 400 gradually rises.

[0066] As Figures 1 to 3C , Figure 5 shown, on the basis of the above-described embodiment, the linkage element 500 is provided with a drive shaft 510 and a sliding shaft 520. The drive shaft 510 is connected to the folding mechanism 300. The outer jacket 100 is provided with a first sliding groove 110, and the sliding seat 200 is provided with a second sliding groove 210. The sliding shaft 520 is passed through the first sliding groove 110 and the second sliding groove 210;

[0067] When the sliding seat 200 is in the linkage interval, the sliding shaft 520 is locked with the first sliding groove 110, causing the linkage element 500 to remain stationary relative to the outer jacket 100; when the sliding seat 200 is in the idle stroke interval, the sliding shaft 520 is locked with the second sliding groove 210, causing the linkage element 500 to remain stationary relative to the sliding seat 200.

[0068] On the basis of the above-described embodiment, the first sliding groove 110 includes a first straight segment 111 and a first inclined groove segment 112. The first inclined groove segment 112 is connected to one end of the first straight segment 111. The second sliding groove 210 includes a second straight segment 211 and a second inclined groove segment 212. The second inclined groove segment 212 is connected to one end of the second straight segment 211;

[0069] When the linkage element 500 is in the first connection state, the sliding shaft 520 is located at the end of the first inclined groove segment 112 and the second straight segment 211. The end of the first inclined groove segment 112 restricts the movement of the linkage element 500 relative to the outer jacket 100 by abutting against the sliding shaft 520, and the sliding shaft 520 is allowed to move within the second straight segment 211;

[0070] When the sliding seat 200 is in the switching interval, the sliding shaft 520 is located in the first inclined groove segment 112 and the second inclined groove segment 212. The sliding direction of the sliding seat 200 determines whether the sliding shaft 520 tends to the end of the first inclined groove segment 112 or the end of the second inclined groove segment 212;

[0071] When the linkage element 500 is in the second connection state, the sliding shaft 520 is located at the ends of the first straight segment 111 and the second inclined slot segment 212. The end of the second inclined slot segment 212 restricts the movement of the linkage element 500 relative to the sliding seat 200 by abutting against the sliding shaft 520, and the sliding shaft 520 is allowed to move within the first straight segment 111.

[0072] The linkage element 500 is preferably a long rod-shaped structure. The drive shaft 510 and the sliding shaft 520 are respectively located at both ends of the linkage element 500. The drive shaft 510 is hinged to the folding mechanism 300, which enables the sliding shaft 520 to swing around the drive shaft 510, so that the sliding shaft 520 can switch into the first straight segment 111 or the second straight segment 211. When the sliding shaft 520 is located within the first inclined slot segment 112 or the second inclined slot segment 212, it can be locked together with the outer jacket 100 or the sliding seat 200.

[0073] On the basis of the above embodiment, both the first straight segment 111 and the second straight segment 211 are arranged along the sliding direction of the sliding seat 200. The first straight segment 111 and the second straight segment 211 are parallel and non-coincident. Both the first inclined slot segment 112 and the second inclined slot segment 212 are inclined to the sliding direction of the sliding seat 200. The first inclined slot segment 112 inclines towards the second straight segment 211, and the end of the first inclined slot segment 112 is on the same straight line as the second straight segment 211. The second inclined slot segment 212 inclines towards the first straight segment 111, and the end of the second inclined slot segment 212 is on the same straight line as the first straight segment 111.

[0074] Since both the first straight segment 111 and the second straight segment 211 are arranged along the sliding direction of the sliding seat 200, this means that when the sliding seat 200 slides, the sliding shaft 520 can slide along the straight segment; while there is an angular deviation between the inclined slot segment and the sliding direction of the sliding seat 200, which means that the inclined slot segment can lock the sliding shaft 520, thereby restricting the sliding of the linkage element 500.

[0075] As Figure 1 shown, on the basis of the above embodiment, the number of both the folding mechanism 300 and the linkage element 500 is two. The two linkage elements 500 are respectively located on both sides of the sliding seat 200. The two side walls of the sliding seat 200 are close to the two side walls of the outer jacket 100. The first sliding slots 110 are arranged on both side walls of the outer jacket 100, and the second sliding slots 210 are arranged on both side walls of the sliding seat 200.

[0076] By respectively arranging a folding mechanism 300 and a linkage element 500 on both sides of the sliding seat 200, the balance and stability of the entire structure during operation can be ensured. This design can effectively avoid tilting or jamming caused by unilateral force, making the cup holder more stable and safe. Moreover, the two linkage elements 500 work together to synchronously drive the two folding mechanisms 300 to act, ensuring the consistency of the movement of the cup holder seat 400 during the lifting process.

[0077] On the basis of the above embodiment, the sliding seat 200 is provided with two limit members 220. The two limit members 220 are respectively close to the two side walls of the sliding seat 200. A limit gap is reserved between the limit member 220 and the side wall of the sliding seat 200. The linkage element 500 is arranged in the limit gap, and the front and back surfaces of the linkage element 500 are respectively abutted against the side wall of the sliding seat 200 and the limit member 220.

[0078] The cooperation between the limit member 220 and the side wall of the sliding seat 200 plays a role of guiding and limiting. The linkage element 500 is clamped between the side wall of the sliding seat 200 and the limit member 220, so that it can only move along a predetermined direction. This structure effectively prevents the linkage element 500 from yawing or tilting during the movement process, and improves the stability of the movement of the linkage element 500.

[0079] As Figures 1 to 5 shown, on the basis of the above embodiment, the folding mechanism 300 is arranged as a scissor structure. The folding mechanism 300 includes a first folding arm 310, a second folding arm 320 and a hinge shaft 330. The first folding arm 310 and the second folding arm 320 are hinged by the hinge shaft 330. One end of the first folding arm 310 is hinged to the cup holder seat 400. The drive shaft 510 is rotatably connected to the other end of the first folding arm 310. The other end of the first folding arm 310 is slidably connected to the sliding seat 200 through the drive shaft 510. One end of the second folding arm 320 is slidably connected to the cup holder seat 400, and the other end of the second folding arm 320 is hinged to the sliding seat 200.

[0080] The scissor structure is a commonly used lifting and folding structure. Its core principle is to realize the lifting movement of the cup holder seat 400 through the relative rotation of the first folding arm 310 and the second folding arm 320. Among them, the linkage element 500 is hinged to the other end (sliding end) of the first folding arm 310 through the drive shaft 510. When the linkage element 500 is locked together with the outer jacket 100 (in the first connection state), as the sliding seat 200 slides, the linkage element 500 moves relative to the sliding seat 200, and then pushes or pulls the other end of the first folding arm 310. The other end of the first folding arm 310 slides relative to the sliding seat 200, so that the first folding arm 310 and the second folding arm 320 rotate relatively, and then change the geometric state of the folding mechanism 300, and finally drive the cup holder seat 400 to lift.

[0081] It should be noted here that a torsion spring is provided at one end of the first folding arm 310 (the end hinged to the cup holder base 400). The two ends of the torsion spring are respectively connected to the first folding arm 310 and the cup holder base 400. The torsion spring always applies a torsion force to the folding mechanism 300 through the first folding arm 310 to drive the cup holder base 400 to rise.

[0082] The working principle of this pull-out and foldable vehicle cup holder is as follows:

[0083] As Figure 1 、 Figure 2A 、 Figure 3A 、 Figure 4A shown, when the sliding seat 200 is in the deployed position, the cup holder base 400 is located outside the outer frame 100. The end of the first inclined groove section 112 coincides with the rear end of the second straight section 211. The sliding shaft 520 is located at the end of the first inclined groove section 112 and within the second straight section 211. The first inclined groove section 112 is inclined with respect to the sliding direction of the sliding seat 200. This means that the sliding shaft 520 is resisted by the first inclined groove section 112, so that the linkage element 500 and the outer frame 100 are locked together, and the linkage element 500 is allowed to move relative to the sliding seat 200, that is, the linkage element 500 is in the first connection state.

[0084] As Figure 1 、 Figure 2B 、 Figure 3B 、 Figure 4B 、 Figure 5 shown, when the sliding seat 200 starts to retract, it first passes through the linkage interval. Since the sliding shaft 520 is resisted by the first inclined groove section 112 and at the same time the sliding shaft 520 can slide within the second straight section 211, the linkage element 500 moves relative to the sliding seat 200. The linkage element 500 pushes one end of the first folding arm 310 to slide through the drive shaft 510, so that the folding mechanism 300 deforms, and then drives the cup holder base 400 to gradually descend through the folding mechanism 300.

[0085] When the sliding seat 200 reaches the first switching position, the cup holder seat 400 descends to the lowest position, and the cup holder seat 400 is about to enter the front opening of the outer jacket 100. At this time, the sliding shaft 520 enters the starting end of the second inclined slot section 212. As the sliding seat 200 continues to retract within the switching range, the second inclined slot section 212 drives the sliding shaft 520 to move (the sliding shaft 520 itself cannot move and can only move within the first inclined slot section 112 under the traction of the second inclined slot section 212). The sliding shaft 520 gradually moves towards the starting end of the first inclined slot section 112 and the end of the second inclined slot section 212, that is, the sliding shaft 520 transfers at the intersection of the first inclined slot section 112 and the second inclined slot section 212, and the first connection state gradually changes to the second connection state. When the sliding seat 200 reaches the second switching position, the sliding shaft 520 is located at the starting end of the first inclined slot section 112 and the end of the second inclined slot section 212.

[0086] As Figure 1 , Figure 2C , Figure 3C , Figure 4C As shown, when the sliding seat 200 enters the idle stroke range, the cup holder seat 400 gradually enters the outer jacket 100. At this time, the sliding shaft 520 is located at the ends of the first straight section 111 and the second inclined slot section 212, and the sliding shaft 520 is resisted by the second inclined slot section 212, so that the linkage element 500 is locked together with the sliding seat 200, and the linkage element 500 is allowed to slide relative to the outer jacket 100, that is, the linkage element 500 is in the second connection state. At this time, the linkage element 500 moves together with the sliding of the sliding seat 200, and the linkage element 500 cannot push the first folding arm 310 to move through the drive shaft 510, so that the cup holder seat 400 remains stationary. As the sliding seat 200 continues to slide, it finally enters the storage position.

[0087] When the sliding seat 200 moves from the storage position towards the unfolding direction, the linkage element 500 acts along the path opposite to the retraction process. After entering the switching range, the locking state between the linkage element 500 and the sliding seat 200 is gradually released and gradually restored to the first connection state, so that a linkage relationship is established between the sliding seat 200 and the cup holder seat 400 in the linkage range, and the cup holder seat 400 rises accordingly.

[0088] Embodiment 1:

[0089] As Figure 1 shown, it further includes a spring winding 230. The spring winding 230 is installed on the sliding seat 200 and is connected to the outer jacket 100. The spring winding 230 always exerts a movement tendency on the sliding seat 200 to make it extend and slide.

[0090] The function of the spring winding 230 is to provide an outward stretching tendency force for the sliding seat 200, so that the sliding seat 200 can automatically unfold under the action of the spring winding 230 and retract to the hidden position manually.

[0091] Embodiment 2:

[0092] It further includes a motor, which is installed on the sliding seat 200. A gear is provided on the rotating shaft of the motor, and a rack is provided on the outer sleeve 100. The gear meshes with the rack, and the motor can drive the sliding seat 200 to slide through forward and reverse rotations.

[0093] In Embodiment 2, a motor is added as a power source. The outer sleeve 100 is provided with a rack, and a gear is installed on the rotating shaft of the motor. The gear meshes with the rack structure, so the motor can drive the sliding seat 200 to extend and retract through forward and reverse rotations.

[0094] In both Embodiment 1 and Embodiment 2, a damper can be provided between the sliding seat 200 and the outer sleeve 100 to make the sliding seat 200 more stable when extending and retracting.

[0095] As Figures 1 to 5 shown, a vehicle includes a pull-out and foldable vehicle cup holder. The cup holder is usually installed in the central armrest box area of the vehicle, at the rear seat armrest, or in the door storage compartment. When the cup holder is unfolded, during the initial stage of the sliding seat 200 being pulled out, it passes through an idle stroke interval. At this time, the cup holder seat 400 is at the lowest position. After passing the first switching position, the cup holder seat 400 rises synchronously with the movement of the sliding seat 200; when being stored, the cup holder seat 400 first descends synchronously with the retraction of the sliding seat 200. When the sliding seat 200 reaches the first switching position, the cup holder seat 400 descends to the lowest position, and then the sliding seat 200 continues to retract in the idle stroke interval after passing through the switching interval.
