Description

Technical Field

[0001] This application relates to the field of automotive parts technology, and in particular to a variable track flip cup holder. Background Technology

[0002] As an important functional component inside a car for placing items such as water cups and beverage bottles, the design rationality of cup holders directly affects ease of use and the utilization rate of interior space.

[0003] Traditional car cup holders are mostly fixed or flip-top designs. Fixed cup holders take up storage space in the car when not in use, while simple flip-top cup holders typically only allow the flip to open and close around a single fixed axis. During opening, the flip often protrudes outwards, requiring the center console to reserve more internal space in the direction the flip flips. Furthermore, when the flip is not fully open, it can limit the size of the cup holder opening and the ease of accessing items. Therefore, we propose a cup holder structure that optimizes space utilization and improves usability during opening and closing. Summary of the Invention

[0004] The purpose of this application is to provide a variable track flip cup holder that can reduce the space occupied by the center console.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: a variable-track flip cup holder, including a flip cover, a cup holder, a first limiting part for limiting the rotation of the flip cover in a first direction, and a second limiting part for limiting the rotation of the flip cover in a second direction. The first limiting part is used to allow the flip cover to rotate around an axis located outside the flip cover, and the second limiting part is used to allow the flip cover to rotate around an axis on the flip cover. The flip cover is simultaneously limited by the first limiting part and the second limiting part when it is closed and opened, so that the flip cover rotates on its own axis while revolving around the axis. The second limiting part includes at least two acceleration parts with different arcs or inclination angles. In the direction of the flip cover opening, the part located at the front end allows the flip cover to rotate faster, and the part located at the rear end allows the flip cover to rotate slower, so as to reduce the outer space occupied by the flip cover when it is at the front end of the revolution, and to allow the internal space of the cup holder to be released in advance when it is at the front end of the revolution.

[0006] As a preferred embodiment, the first limiting part includes a swing arm, and the flip cover revolves around the swing arm; the second limiting part includes a connecting part connected to the flip cover and a limiting groove for limiting the movement of the connecting part. When the flip cover revolves around the swing arm, the connecting part simultaneously causes the flip cover to rotate. The flip cover is limited by the limiting groove to maintain or change its rotation speed, so that the connecting part is always kept within the limiting groove and the connecting part is always kept in a fixed position on the flip cover.

[0007] As a preferred embodiment, when the flip cover rotates around the swing arm and does not rotate on its own axis, the point corresponding to the connecting part forms an arc-shaped first trajectory, and the end of the swing arm forms a second trajectory when it rotates. The front end of the limiting groove is located in front of the first trajectory, so that the flip cover is subjected to the limiting groove to accelerate its rotation throughout the entire limiting process within the limiting groove. The acceleration of the flip cover's rotation is different when it passes through different segments of the limiting groove, and the acceleration is affected by the deviation of the limiting groove from the first trajectory. As the deviation increases, the corresponding acceleration increases.

[0008] As a preferred embodiment, the distance between the connection point of the swing arm and the flip cover, the connection point of the connecting part and the flip cover, and the distance between the two are greater than half the length of the flip cover, so as to reduce the influence of the swing arm when the flip cover rotates; when the flip cover reaches the revolution angle a, its rotation reaches the angle b, where 10°≤a≤30°, 45°≤b≤100°.

[0009] Furthermore, where 60°≤b≤80°, the limiting groove includes at least three acceleration sections, the two acceleration sections at the beginning and end are a fast section and a slow section respectively, and the acceleration section in the middle is a transition section. The transition section is adapted to reduce the rotation acceleration of the flip cover from the value of the fast section to the value of the slow section in sequence.

[0010] As a preferred embodiment, the variable track flip cup holder also includes a reset member, which is mounted on the flip cover on one side and on the cup holder on the other side. The reset member is stretched and deformed when the flip cover is closed and returns to its original shape when the flip cover is opened and stored.

[0011] As a preferred embodiment, the outer side of the cup holder is provided with a protective structure and a guide structure. The protective structure is adapted to wrap around and limit the guide structure. The guide structure includes a guide portion disposed along the edge of the limiting groove and a sliding portion that guides and engages with the guide portion. The sliding portion includes a first engaging portion that engages with the guide portion and a second engaging portion that engages with the limiting groove. The connecting portion passes through the limiting groove and is hinged to the second engaging portion.

[0012] As a preferred embodiment, the outer side of the cup holder is also provided with a locking structure. The locking structure includes a locking groove integrally formed on the cup holder and a locking rod slidably disposed in the locking groove. The locking groove includes two guide grooves on the left and right sides, and a recess for locking is formed in the middle. The locking rod is installed on the guide structure. When the flip cover is closed, the guide structure is located in the recess. The guide structure is acted upon by the reset member to make the locking rod elastically abut against the recess. When the cover is opened, the flip cover is pressed to make the other side of the flip cover lift up. At this time, the guide structure moves upward to make the locking rod leave and move to the top of the groove on the left side. Then the flip cover is released, and the reset member resets to make the locking rod move down along the groove on the left side to release the lock. When the flip cover is closed again, the flip cover is pressed to make the flip cover and the guide structure return to their original path. During the process, the guide structure moves upward to make the locking rod move along the groove on the right side until the flip cover reaches the closed position. At this time, the locking rod returns to the recess to form an elastic abutment.

[0013] As a preferred embodiment, the first mating part is a gear, and the corresponding guide part is a rack. The first mating part also includes an extended limiting protrusion, which is adapted to engage with the outer side of the guide part to limit the engagement so that the first mating part as a whole does not deviate from the track corresponding to the guide part.

[0014] As a preferred embodiment, the rack has an arc-shaped transition at the change in the limiting groove. The arc-shaped transition is adapted to sequentially reduce the rotational speed of the flap after reaching its maximum outer diameter. At the same time, the arc-shaped transition is adapted to reduce the mating clearance between the first mating part and the guide part when the guide part passes through the change in the limiting groove. The guide structure also includes a damping element, which is adapted to adjust the rotational resistance of the gear so that the guide structure maintains a relatively uniform moving speed when sliding up and down.

[0015] Compared with the prior art, the beneficial effects of this application are as follows:

[0016] By making the front part of the flip cover rotate faster and the rear part rotate slower, the flip cover can quickly rotate to its largest outer diameter position in the early stage of rotation, thereby reducing the outer space occupied by the flip cover when it is at the front of the revolution, and allowing the internal space of the cup holder to be released in advance when it is at the front of the revolution. In the early stage of the revolution, most of the top of the flip cover is above the cup holder. At this time, the flip cover can quickly rotate to the position of the largest outer diameter position before entering the cup holder, which can effectively reduce the space occupied.

[0034] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0035] Example:

[0036] Reference Figures 1 to 11 This embodiment proposes a variable-track flip cup holder, including a flip cover 1 and a cup holder 2. The internal space of the cup holder 2 is used to hold cups. When the flip cover 1 is changed from a closed state to a retracted state, the interior of the flip cover 1 can be flipped to become part of the inner wall for holding the cup, i.e. Figure 2 As shown, the inner wall 101 of the lid of the flip cover 1 forms the second cavity wall 92, and the cup holder 2 forms the first cavity wall 91. The first cavity wall 91 and the second cavity wall 92 together form the cup-containing space. The outer edge 3 of the cup holder 2 extends outward, so that the internal structure of the cup holder is hidden in the center console after installation.

[0037] In this application, the process of flip cover 1 changing from the closed state to the open state is defined as the storage state of flip cover 1.

[0038] The aforementioned cup holder also includes a first limiting part for restricting the rotation of the flip cover 1 in a first direction and a second limiting part for restricting the rotation of the flip cover 1 in a second direction. The first limiting part is used to cause the flip cover 1 to revolve around a first axis located outside the flip cover 1, and the second limiting part is used to cause the flip cover 1 to rotate on its own axis around a second axis on the flip cover 1. The flip cover 1 is simultaneously restricted by the first and second limiting parts when closing and opening, so that the flip cover 1 revolves around the axis while rotating on its own axis. The second limiting part includes at least two acceleration sections with different curvatures or inclination angles. In the direction of closing the flip cover 1, the section located at the front end causes the flip cover 1 to rotate faster, and the section located at the rear end causes the flip cover 1 to rotate slower, so as to reduce the outer space occupied by the flip cover 1 when it is at the front end of the revolution, and to release the internal space of the cup holder 2 in advance when it is at the front end of the revolution, while making the flip cover 1 stable when it is at the rear end of the revolution (because the rotation speed is slower in the later stage). In fact, no matter how the limiting groove 6 is changed, the shape of the flip cover 1 at the initial point and the end point when it rotates from the closed state to the stored state does not change.

[0039] It is worth mentioning that, regarding the rotation angle of the flip cover 1, it is necessary to consider that when the flip cover 1 revolves, it will also rotate relative to its initial posture. Therefore, in the above description of the rotation of the flip cover 1, the rotation angle of the flip cover 1 at each moment is the change value of the rotation of the flip cover 1 relative to its initial state and the subsequent rotation value of the flip cover 1 relative to that state. This change value includes the rotation angle caused by the revolution.

[0040] Without the above-mentioned setting on the limiting groove 6 (i.e., segmenting to change the rotation speed of the flip cover 1), the flip cover 1 rotates synchronously during its revolution, and the overall rotation speed is stable and uniform. Therefore, the flip cover 1 rotates slower than in the technical solution of this embodiment. Consequently, the opening formed by the flip cover 1 and the internal space of the cup holder 2 opens slowly, and only after rotating at least halfway can the opening at the top of the internal space be opened larger, at which point the cup can be placed. In this embodiment, however, because the rotation of the flip cover 1 accelerates at the front end, it quickly opens to a larger opening, allowing the internal space of the cup holder to be used earlier, reducing waiting time.

[0041] Specifically, refer to Figures 1 to 3 As shown, the flip cover 1 rotates on its own axis while revolving around the central axis. This design saves more space than the flip cover 1 not rotating on its own axis but only revolving around the central axis to reach the storage state. Although the flip cover 1 still revolves around the first axis first, its simultaneous rotation on its own axis is equivalent to slowly folding up the outermost part at the same time, thereby achieving the purpose of saving space. Figure 5 The flip cover 1 shown does not rotate during the process. Figure 5 The upper and middle sections take up a lot of space; refer to... Figure 8 , Figure 8 The state shown is the same as Figure 5 The space occupied by the upper center flip cover is similar, but Figure 8 The swing angle (i.e., revolution angle) of the swing arm 10 shown is significantly smaller than that of the other arm. Figure 5 The state shown by the flip cover 1 at the top center.

[0042] Reference Figure 4 , Figure 4 In state (1), the limiting slot 6 is not set to accelerate, and the flip cover 1 is almost touching the wall of the cup holder 2. Figure 4 After the rotation acceleration, a gap remains between the cup holder 2 and the wall of the cup holder 2, thus the cup holder 2 can further reduce its space occupation. Of course, referring to Figure 2 In fact, the right side of cup holder 2 can be slightly moved to the left without reducing the space available for holding the cup. That is, existing similar cup holders, in their design... Figure 2 The right side shown generally needs to have a large gap so that the flip cover 1 does not cause interference during opening.

[0043] Reference Figure 9 , Figure 9 In the middle 'a', the flip cover 1 has a revolution angle of 10 degrees (small amplitude) and no additional increase in its rotation angle. At this time, the outermost space occupied by the flip cover 1 has not reached its maximum value. Figure 9 As shown in diagram b, the revolution angle is the same as in diagram a, but the rotation angle is increased. At this point, when the revolution angle is very small, continuing to rotate along diagram b will not add any additional space. (See also...) Figure 9 In section c, the rotation angles of c and b are similar, but c occupies more space when it reaches this angle. Therefore, it can be understood that rotating while revolving helps reduce space occupation; furthermore, accelerating the rotation angle of the flip cover 1 to its maximum occupied state during the first half of the revolution will further reduce the overall space occupation. In the early stage of the revolution, most of the top of the flip cover 1 is above the cup holder. At this time, quickly rotating the flip cover 1 to its maximum outer diameter occupied position before entering the cup holder can effectively reduce space occupation.

[0044] Based on the above, the second limiting part rotates by limiting the flip cover 1. The power for the flip cover 1 to rotate comes from the action of the second limiting part when it revolves. The limiting groove 6 actually plays a guiding role when limiting the movement of the connecting part 14. The rotation speed corresponding to the revolution can be controlled by the slope of each point of the limiting groove 6.

[0045] Reference Figure 3 The first limiting part mainly includes a swing arm 10, and the flip cover 1 revolves around the swing arm 10. The swing arm 10 can be provided at both ends of the inner side of the bottom of the flip cover 1, as shown in the figure. Figure 2 , Figure 5 and Figure 11 As shown, the hinge joint can be referenced after installation. Figure 5 The swing arm connection 102 on the left side corresponds to the second trajectory A shown by the dotted line on the left; the connecting part 14 can be set at the ends of both sides of the flip cover 1. If the flip cover 1 does not rotate, the movement trajectory of the connecting part 14 is... Figure 5 The first trajectory B on the right side of the middle. (As shown in the image) Figure 11 As shown, during the rotation process, a reset member 15 can be set as the power for the rotation of the flip cover 1. When the flip cover 1 is closed, the reset member 15 is deformed, and when the flip cover 1 is opened, the reset member 15 is restored.

[0046] Reference Figure 2 The second limiting part mainly includes a connecting part 14 that connects to the flip cover 1 and a limiting groove 6 for limiting the movement of the connecting part 14. When the flip cover 1 revolves around the swing arm 10, the connecting part 14 simultaneously causes the flip cover 1 to rotate. The connecting part is limited by the limiting groove 6 to maintain or change its rotation speed, so that the connecting part 14 is always kept within the limiting groove 6 and always remains in the fixed position of the flip cover 1. (Continue referring to...) Figure 5 When the flip cover 1 rotates around the swing arm 10 without rotating on its own axis, the point corresponding to the connecting part 14 forms an arc-shaped first trajectory B, and the end of the swing arm 10 forms a second trajectory A when it rotates. If the flip cover 1 does not rotate on its own axis, its trajectory rotates along the first trajectory B. However, when the flip cover 1 rotates on its own axis, the connecting part 14 needs to move within the limiting groove 6 as the flip cover 1 revolves. During the movement, due to the hinge between the swing arm 10 and the flip cover 1, the flip cover 1 will rotate as the position of the connecting part 14 changes within the limiting groove 6. Considering two adjacent points, the greater the slope between the upper and lower points, the greater the difference in their horizontal distance. During rotation, the two adjacent points can be considered as the difference in rotation angle between two adjacent angles during revolution. In other words, the greater the slope of the straight line formed between the two adjacent points, the greater the change in rotation angle, and therefore the greater the acceleration of the corresponding rotation angle.

[0047] Based on the above principles, the rotation speed can be controlled by changing the shape of the limiting groove 6, which is the change in the angle of rotation of the flip cover 1 per unit time. The faster the rotation, the larger the rotation angle for each 1° revolution. Of course, the above changes are based on the variation pattern of the same part of the limiting groove 6. For ease of explanation, assume that the limiting groove 6 only includes two ends. The first part is the part that accelerates the rotation. For example, when reaching the storage state, it needs to revolve 60° and rotate 90°. By using different curvatures at the two ends, the first half can occupy 1 / 3 of the revolution angle. That is, when the flip cover 1 revolves 20°, it achieves a 60° rotation. After the rotation reaches 60° (in some cases, the flip cover 1 reaches its maximum outermost point before this value), its outermost part will no longer occupy space. Therefore, after the flip cover 1 rotates a small distance at the beginning, it will not continue to increase the occupied distance, allowing the flip cover 1 to further reduce space occupation during the rotation process.

[0048] Reference Figure 12 , Figure 12 This is a schematic diagram of an optional limiting groove. The top of the limiting groove 6 is inclined. When the connecting part moves downward, it interacts with the limiting groove 6. When the front end of the limiting groove 6 interacts with the connecting part, the connecting part is guided to the left so that the entire flip cover moves to the left at an accelerated speed, that is, the flip cover rotates faster around the swing arm connection.

[0049] Cup holders are typically located in the center console area of ​​a car (the area between the driver's and passenger's seats). This area is where car control buttons, wireless charging modules, and in-car refrigerators are concentrated. Reducing the overall space occupied by cup holders helps to free up space in the functional areas, thereby increasing space utilization.

[0050] The following combination Figures 5 to 9 This provides a detailed explanation of the specific settings for revolution and rotation. For example... Figure 5 The area corresponding to the limiting slot 6, that is, the front end of the limiting slot 6, is located in front of the first trajectory B (refer to...). Figure 13 Ahead is Figure 13 The left side of the second trajectory B shown is used to ensure that the flip cover 1 is accelerated to rotate by the limiting groove 6 throughout the entire limiting process within the limiting groove 6. The acceleration of the flip cover 1's rotation is different when it passes through different segments of the limiting groove 6, and the acceleration is affected by the deviation of the limiting groove 6 from the first trajectory B. As the deviation changes, the acceleration increases. The deviation change here refers to the difference in distance between the upper and lower points and the first trajectory B. This is essentially equivalent to the slope change mentioned earlier. This is a microscopic expression, namely the change in the difference between δ1 (the distance difference between the upper point and the first trajectory B) and δ2 (the distance difference between the lower point and the first trajectory B). Countless such adjacent points form the curve corresponding to the limiting groove 6.

[0051] Reference Figure 1 Preferably, the distance between the connection point of the swing arm 10 and the flip cover 1, the connection point of the connecting part 14 and the flip cover 1, and the distance between them is greater than half the length of the flip cover 1, so as to reduce the influence of the swing arm 10 when the flip cover 1 rotates. If the distance between the above-mentioned connection points is too small, the setting of the limiting groove 6 will be limited to a very small range during revolution, thereby affecting the flexibility of the flip cover 1's rotation.

[0052] Regarding the range of accelerated rotation mentioned above, it is limited by the following range: when the flip cover 1 reaches the revolution angle 'a', its rotation reaches angle 'b', where 10°≤a≤30°, 45°≤b≤100°. If the value of 'a' is too small, the flip cover 1 will rotate too quickly during the opening process. This requires a large force and must also consider the effects of wear and inertia; therefore, excessively fast rotation speed is not considered. Within the above range, the flip cover 1 can rotate to its outermost and relatively largest position as quickly as possible without rotating too fast. Optional values ​​include, for example, a = 15°, b = 60°, a = 20°, b = 75°, or a = 25°, b = 80°. Figure 6 As shown in the figure, the flip cover 1 can actually reach the storage state when it has rotated about 60°. Therefore, the value of 'a' is limited to less than half. That is, before the first half of the revolution is completed, the flip cover 1 needs to complete its rotation to the range of 45° to 100°.

[0053] Further options include 60°≤b≤75° and 95°≤b≤100°. The limiting slot 6 includes at least three acceleration sections: the first and last two are the fast and slow sections, respectively; the middle section is the transition section, designed to gradually reduce the rotation acceleration of the flip cover 1 from the fast section to the slow section. The value of b can be greater than 90°. Even if the rotation angle exceeds 90° (the angle in the retracted state), a corresponding setting can be made in the subsequent limiting slot 6 to allow the flip cover 1 to rotate back to the 90° retracted state, thus quickly freeing up the space between the flip cover 1 and the cup holder. (Refer to...) Figure 10 , Figure 10 The revolution angle shown is approximately 30° and the rotation angle is approximately 80°. At this point, the flip cover 1 can continue to rotate to 90°, as shown. Figure 10 It is evident that there is still a certain distance between the flip cover 1 and the cup holder 2 on the right side. Therefore, even if the angle exceeds 90°, it will not cause interference between the flip cover 1 and the cup holder 2. When the flip cover 1 is tilted towards the closure when the angle is less than 90°, the top of the accommodating space is smaller. When the angle is greater than 90°, the top of the flip cover 1 is essentially flared, making it easier to place mainstream cylindrical (such as teacups) or conical (such as milk tea cups) cups. In other words, the cup can be placed before the flip cover 1 is fully rotated, reducing the waiting time for the flip cover 1 to open.

[0054] The above describes the specific principle by which the limiting slot 6 changes the rotation speed of the flip cover 1. Based on this principle, the rotation speed of the flip cover 1 can also be changed in different storage states. For example, in the preferred scenario of fast rotation followed by slow rotation, the flip cover 1 can be specifically set and tested so that the rapid rotation at the front end can ensure stability while unfolding as quickly as possible, thus reducing space occupation and opening the cup holder's storage space for use as soon as possible. In fact, this setting also has another advantage: the latter half of the process is slower when the reset component 15 is reset. When inserting the cup, even if the cup is too large, it can still be used. The flip cover 1 stops early when it is flipped to a certain extent (e.g., when the rotation angle is 80°). At this time, the reset component 15 has not fully retracted, but the flip cover 1 has already clamped the cup because the cup is too wide. At this time, the reset component 15 does not continue to reset, which can ensure this clamping state, thus allowing for the placement of wider cups.

[0055] To a certain extent, when the flip cover 1 is fully closed, the reset component 15 has the greatest deformation and therefore the greatest restoring force. At this time, the flip cover 1 rotates rapidly during the process, and is only guided, with a relatively short period of resistance. However, when the flip cover 1 does not have a limited rotation speed, it is generally slower throughout the process due to the damping component 12 for stable use. The reset component 15 continuously encounters resistance during the recovery process when the deformation is at its maximum, which may lead to premature fatigue of the reset component 15. In this application, the rotation of the flip cover 1 is faster at the front end of its revolution, at which time the reset component 15 can recover more quickly, thereby reducing its fatigue. Since the connection between the flip cover 1 and the swing arm 10 is affected by gravity after the flip cover 1 rotates to a certain angle and does not completely depend on the reset of the reset component 15, there will be no subsequent failure of the flip cover 1 to be fully closed due to insufficient restoring force of the reset component 15.

[0056] As a preferred embodiment, the reset member 15 is mounted on one side of the flip cover 1 and on the other side of the cup holder 2. The reset member 15 is stretched and deformed when the flip cover 1 is closed, and returns to its original shape when the flip cover 1 is opened and stored. The reset member 15 can be a coil spring or a tension spring, etc.

[0057] To ensure proper rotation of the flip cover 1, the outer side of the cup holder 2 is equipped with a protective structure and a guide structure 4. The protective structure is adapted to wrap around and limit the guide structure 4. The guide structure 4 includes a guide portion 7 along the edge of the limiting groove 6 and a sliding portion 5 that guides and engages with the guide portion 7. The sliding portion 5 includes a first engaging portion that engages with the guide portion 7 and a second engaging portion 13 that engages with the limiting groove 6. A connecting portion 14 passes through the limiting groove 6 and is hinged to the second engaging portion 13. The guide structure 4 also includes a damping element 12, which is adapted to adjust the rotational resistance of the gears so that the guide structure 4 maintains a relatively uniform moving speed when sliding up and down.

[0058] Reference Figure 2 , Figure 3The outer side of the cup holder 2 is also provided with a locking structure 8. The locking structure 8 includes a locking groove integrally formed on the cup holder 2 and a locking rod 11 slidably disposed in the locking groove. The locking groove includes two guide grooves on the left and right, and a recess 81 for locking is formed in the middle. The locking rod 11 is installed on the guide structure 4. When the flip cover 1 is closed, the guide structure 4 is located in the recess 81. The guide structure 4 is acted upon by the reset member 15 to make the locking rod 11 elastically abut against the recess 81. When the cover is opened, the flip cover 1 is pressed to make When the other side of the flip cover 1 is raised, the guide structure 4 moves upward to disengage the locking lever 11 and move it to the top of the groove on the left. Then, the flip cover 1 is released, and the reset member 15 resets, causing the locking lever 11 to descend along the groove on the left to release the lock. When the flip cover 1 is closed again, pressing it causes the flip cover 1 and guide structure 4 to return along their original paths. During this process, the guide structure 4 moves upward, causing the locking lever 11 to move along the groove on the right until the flip cover 1 reaches the closed position. At this point, the locking lever 11 returns to the recess 81 to form an elastic abutment. The first mating part is a gear, and the corresponding guide part 7 is a rack. The first mating part also includes an extended limiting protrusion, which is suitable for limiting the engagement with the outer side of the guide part 7 to ensure that the entire first mating part does not deviate from the corresponding track of the guide part 7. Of course, when the limiting groove 6 has a large arc change, the gear and rack engagement can be changed to a roller and a grooved strip structure to prevent interference in areas with large angle changes.

[0059] As a preferred embodiment, the rack has an arc-shaped transition at the change of the limiting groove 6. The arc-shaped transition is suitable for successively reducing the rotation speed of the flip cover 1 after reaching the maximum outer diameter. At the same time, the arc-shaped transition is suitable for reducing the mating gap between the first mating part and the guide part 7 when the guide part 7 passes through the change of the limiting groove 6.

Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection claimed by this application is defined by the appended claims and their equivalents.

Claims

1. A variable-track flip cup holder, characterized in that, The device includes a flip cover, a cup holder, a first limiting part for limiting the flip cover to rotate in a first direction, and a second limiting part for limiting the flip cover to rotate in a second direction. The first limiting part is used to allow the flip cover to rotate about an axis located outside the flip cover, and the second limiting part is used to allow the flip cover to rotate about an axis on the flip cover. The flip cover is simultaneously limited by the first limiting part and the second limiting part when it is closed and opened, so that the flip cover rotates on its own axis while revolving around the axis. The second limiting part includes at least two acceleration parts with different curvatures or inclinations. In the direction of the flip opening, the part located at the front end makes the flip rotate faster and the part located at the rear end makes the flip rotate slower, so as to reduce the outer space occupied by the flip when it is in the front part of the revolution and to release the internal space of the cup holder in advance when it is in the front part of the revolution. The first limiting part includes a swing arm, and the flip cover revolves around the swing arm; the second limiting part includes a connecting part connected to the flip cover and a limiting groove for limiting the movement of the connecting part. When the flip cover revolves around the swing arm, the connecting part simultaneously causes the flip cover to rotate. The flip cover maintains or changes its rotation speed due to the limitation of the limiting groove. The connecting part is always kept within the limiting groove and is always kept in a fixed position on the flip cover. The distance between the connection point of the swing arm and the flip cover, the connection point of the connecting part and the flip cover, and the distance between them are greater than half the length of the flip cover, so as to reduce the influence of the swing arm when the flip cover rotates; when the flip cover reaches the revolution angle a, its rotation reaches the angle b, where 10°≤a≤30°, and 95°≤b≤100°. The limiting groove includes at least three acceleration sections. The two acceleration sections at the beginning and end are the fast section and the slow section, respectively. The acceleration section in the middle is the transition section. The transition section is adapted to reduce the rotation acceleration of the flip cover from the value of the fast section to the value of the slow section. When the flip cover rotates more than 90° and reaches its maximum state, and the flip cover continues to rotate, the limiting groove is adapted to make the connecting part rotate back to the storage state of 90°.

2. The variable track flip cup holder as described in claim 1, characterized in that, When the flip cover rotates around the swing arm and does not rotate on its own axis, the point corresponding to the connecting part forms an arc-shaped first trajectory, and the end of the swing arm forms a second trajectory when it rotates. The front end of the limiting groove is located in front of the first trajectory, so that the flip cover is subjected to the limiting groove to accelerate its rotation throughout the entire limiting process within the limiting groove. The acceleration of the flip cover's rotation is different when it passes through different segments of the limiting groove, and the acceleration is affected by the deviation of the limiting groove from the first trajectory. As the deviation increases, the corresponding acceleration increases.

3. The variable track flip cup holder as described in claim 1, characterized in that, It also includes a reset component, which is mounted on the flip cover on one side and on the cup holder on the other side. The reset component is stretched and deformed when the flip cover is closed and returns to its original shape when the flip cover is opened and stored.

4. The variable track flip cup holder as described in claim 3, characterized in that, The outer side of the cup holder is provided with a protective structure and a guide structure. The protective structure is adapted to wrap around and limit the guide structure. The guide structure includes a guide portion provided along the edge of the limiting groove and a sliding portion that guides and engages with the guide portion. The sliding portion includes a first engaging portion that engages with the guide portion and a second engaging portion that engages with the limiting groove. The connecting portion passes through the limiting groove and is hinged to the second engaging portion.

5. The variable track flip cup holder as described in claim 4, characterized in that, The outer side of the cup holder is also provided with a locking structure. The locking structure includes a locking groove integrally formed on the cup holder and a locking rod slidably disposed in the locking groove. The locking groove includes two guide grooves on the left and right, and a recess for locking is formed in the middle. The locking rod is installed on the guide structure. When the flip cover is closed, the guide structure is located within the recess. The guide structure is activated by the reset member to allow the locking rod to elastically abut against the recess. When the cover is opened, pressing the flip cover causes the other side of the flip cover to lift up. At this time, the guide structure moves upward to allow the locking rod to leave and move to the top of the groove on the left side. Then, the flip cover is released, and the reset member resets to allow the locking rod to move downward along the groove on the left side to release the lock. When the flip cover is closed again, pressing the flip cover causes the flip cover and the guide structure to return to their original path. During this process, the guide structure moves upward to allow the locking rod to move along the groove on the right side until the flip cover reaches the closed position. At this time, the locking rod returns to the recess to form an elastic abutment.

6. The variable track flip cup holder as described in claim 4, characterized in that, The first mating part is a gear, and the corresponding guide part is a rack. The first mating part also includes an extended limiting protrusion, which is adapted to limit the engagement with the outer side of the guide part so that the first mating part as a whole does not deviate from the track corresponding to the guide part.

7. The variable track flip cup holder as described in claim 6, characterized in that, The rack has an arc-shaped transition at the change of the limiting groove. The arc-shaped transition is adapted to successively reduce the rotation speed of the flap after reaching the maximum outer diameter. At the same time, the arc-shaped transition is adapted to reduce the fit clearance between the first mating part and the guide part when the guide part passes through the change of the limiting groove. The guide structure also includes a damping element, which is adapted to adjust the rotational resistance of the gear so that the guide structure maintains a relatively uniform moving speed when sliding up and down.
