Description

Technical Field

[0001] This invention belongs to the field of automotive parts technology, and relates to a cup holder mechanism and an automotive cup holder. Background Technology

[0002] With the development of the automotive industry, car cup holders have become an indispensable and practical feature in vehicle interiors. However, in actual use, existing car cup holders often do not provide ideal stability for securing cups (such as cups, mineral water bottles, etc.).

[0003] Currently, most common car cup holders on the market use a simple spring-loaded cup holder (or cup stabilizing clip) structure. Its basic structure is as follows: a movable cup holder is set on the side wall of the cup holder, and a spring is installed between the cup holder and the cup holder body. The elastic force of the spring is used to press the cup holder towards the center of the cup holder, thereby clamping the cup placed in the cup holder.

[0004] To ensure that cups can be easily inserted and removed, the spring force used in the cup clamping mechanism should not be too large, as this limits its clamping force on the cup. Conversely, increasing the spring force to improve the clamping effect will make inserting and removing the cup more difficult, affecting the user experience. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in the prior art by proposing a cup holder mechanism and a car cup holder.

[0006] The objective of this invention can be achieved through the following technical solution: a cup card mechanism, comprising:

[0007] Mounting bracket, wherein the mounting bracket is provided with a sliding groove;

[0008] The chuck is rotatably connected to the mounting bracket to form a lever structure. The chuck has a clamping part and a force-receiving part, which are located at opposite ends of the rotation center of the chuck.

[0009] A locking trigger, comprising a trigger element and a locking element, wherein the trigger element is rotatably connected to the mounting bracket and the locking element is slidably connected to the slide groove;

[0010] The swing range of the abutting part includes the abutting interval; when the abutting part is in the abutting interval, the swing range of the force-receiving part intersects with the movement range of the locking member, and for any angular position of the force-receiving part in the swing range, the locking member has a corresponding stroke position that can form a mechanical limit with it.

[0011] The rotational stroke position of the trigger includes a starting position, a critical position, and an ending position. The critical position is located between the starting position and the ending position. The critical position is set as the angular position of the trigger at the instant when the locking member contacts the force-bearing part during the process of the trigger rotating from the starting position to the ending position. A coupling interval is formed between the starting position and the critical position, and a decoupling interval is formed between the critical position and the ending position.

[0012] When the abutting part is in the abutting range and the trigger is in the coupling range, the locking part is not in contact with the force-bearing part, and the locking part is kinetically coupled with the trigger so that the angular position of the trigger determines the stroke position of the locking part;

[0013] When the abutting part is in the abutting range and the trigger is in the decoupling range, the locking part abuts against the force-bearing part to form a mechanical limit that restricts the abutting part from continuing to retract. The locking part is decoupled from the trigger to allow the trigger to rotate freely relative to the locking part.

[0014] During the retraction process, the force-bearing part swings towards the locking member; when the trigger member is in the coupling range and rotates towards the critical position, the locking member slides towards the force-bearing part.

[0015] Preferably, the critical position is determined by the angular position of the abutting part within the abutting range; the displacement of the locking member when the trigger rotates from the starting position to the critical position is inversely proportional to the retraction amount of the abutting part.

[0016] Preferably, the claw and the locking trigger are arranged sequentially along the cup insertion direction; during the cup insertion process, the abutting part and the trigger retract sequentially, the force-receiving part reaches the predetermined angle position first, and the locking part then slides to the travel position that abuts the force-receiving part.

[0017] Preferably, the sliding direction of the locking member in the slide groove is not the same as the swing direction of the force-receiving part; a locking inclined surface is provided on the side of the force-receiving part near the locking member, the locking inclined surface is inclined relative to the slide groove, and the locking member abuts against the locking inclined surface when it comes into contact with the force-receiving part.

[0018] Preferably, when the abutting part is in the abutting range and the trigger is in the decoupling range, the trigger applies abutting force to the locking ramp through the locking member, and the abutting force is converted into a torque acting on the pawl and causing the abutting part to extend through the locking ramp. The magnitude of the abutting force increases as the angle of rotation of the trigger toward the endpoint position increases.

[0019] Preferably, a first torsion spring is sleeved on the pivot between the claw and the mounting bracket, with both ends of the first torsion spring abutting against the claw and the mounting bracket respectively, and the first torsion spring applying a torque to the abutting part to cause it to extend; a second torsion spring is sleeved on the pivot between the trigger and the mounting bracket, with both ends of the second torsion spring abutting against the trigger and the mounting bracket respectively, and the second torsion spring applying a torque to the trigger to cause it to extend.

[0020] Preferably, the locking trigger further includes a linkage that is disengaged from the trigger, and the locking member is hinged to the linkage. When the trigger is in the coupling range, the torque on the trigger is less than a threshold, and the linkage is circumferentially locked to the trigger to make the locking member and the trigger motion coupled. When the trigger is in the decoupling range, the torque on the trigger is greater than the threshold, and the trigger is allowed to rotate relative to the linkage to make the locking member and the trigger motion decoupled.

[0021] Preferably, the connecting rod is hinged to the trigger, and a third torsion spring is provided between the connecting rod and the trigger. The two ends of the third torsion spring abut against the connecting rod and the trigger, respectively, and the trigger has an abutment surface. When the trigger is located in the coupling interval, the connecting rod abuts against the abutment surface under the action of the third torsion spring. When the trigger is located in the coupling interval and tends towards the critical position, the trigger transmits torque to the connecting rod through the third torsion spring. When the trigger is located in the coupling interval and tends towards the starting position, the trigger transmits torque to the connecting rod through the abutment surface.

[0022] Preferably, the abutting part is provided with an abutting wheel for abutting against the outer wall of the cup.

[0023] A car cup holder includes at least two cup holder mechanisms and a cup holder body. Each cup holder mechanism is mounted on the cup holder body. The clamping portion of the claw of each cup holder mechanism extends into the receiving space of the cup holder body, and the trigger of the locking trigger of each cup holder mechanism extends into the receiving space of the cup holder body.

[0024] Compared with the prior art, the beneficial effects of the present invention are: the locking trigger can mechanically limit the claw without sacrificing the convenience of taking out and putting away the cup, preventing the claw from retracting further, thereby greatly improving the clamping stability of the claw.

Detailed Implementation

[0034] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0035] like Figures 1 to 8 As shown, a cup card mechanism includes:

[0036] Mounting bracket 100, the mounting bracket 100 is provided with a sliding groove 110;

[0037] The pawl 200 is rotatably connected to the mounting bracket 100 to form a lever structure. The pawl 200 has a pressing part 210 and a force-receiving part 220, which are located at opposite ends of the rotation center of the pawl 200.

[0038] Locking trigger 300 includes trigger 310 and locking element 320. Trigger 310 is rotatably connected to mounting bracket 100, and locking element 320 is slidably connected to slide groove 110.

[0039] The swing range of the clamping part 210 includes the clamping interval; when the clamping part 210 is in the clamping interval, the swing range of the force-receiving part 220 intersects with the movement range of the locking member 320, and for any angular position of the force-receiving part 220 in the swing range, the locking member 320 has a corresponding stroke position that can form a mechanical limit with it.

[0040] The rotational stroke position of the trigger 310 includes a starting position, a critical position, and an ending position. The critical position is located between the starting position and the ending position. The critical position is set as the angular position of the trigger 310 at the instant when the locking member 320 and the force-bearing part 220 come into contact during the rotation of the trigger 310 from the starting position to the ending position. A coupling interval is formed between the starting position and the critical position, and a decoupling interval is formed between the critical position and the ending position.

[0041] When the abutting part 210 is in the abutting range and the trigger 310 is in the coupling range, the locking part 320 does not contact the force-receiving part 220, and the locking part 320 is kinetically coupled with the trigger 310 so that the angular position of the trigger 310 determines the stroke position of the locking part 320.

[0042] When the clamping part 210 is in the clamping range and the trigger 310 is in the decoupling range, the locking part 320 abuts against the force-receiving part 220 to form a mechanical limit that restricts the clamping part 210 from continuing to retract. The locking part 320 and the trigger 310 are decoupled in motion so that the trigger 310 is allowed to rotate freely relative to the locking part 320.

[0043] During the retraction process, the force-bearing part 220 swings toward the locking member 320; when the trigger member 310 is in the coupling range and rotates toward the critical position, the locking member 320 slides toward the force-bearing part 220.

[0044] The chuck 200 is configured as a lever structure. When the cup is placed in, it pushes the clamping part 210 back to the clamping position. When the clamping part 210 is in the clamping position, it can abut against the outer wall of the cup, thereby clamping the cup. The force-receiving part 220 can cooperate with the locking member 320 to form a mechanical limit, thereby preventing the clamping part 210 from going beyond the clamping position and continuing to retract. The locking trigger 300 can be triggered by the action of picking up or putting down the cup. When the cup is placed in, it pushes the trigger 310 back. When the trigger 310 retracts, it can cause the locking member 320 to slide to the position where it abuts against the force-receiving part 220.

[0045] The interval between the clamping position of the clamping part 210 when it abuts against the smallest diameter cup and the clamping position of the clamping part 210 when it abuts against the largest diameter cup is called the clamping interval. The clamping part 210 can swing to any angle position within the clamping interval, thereby adapting to cups of different diameters. There is a one-to-one mapping relationship between the sliding position of the locking member 320 and the swing angle of the force-receiving part 220. When cups of different diameters are inserted, the clamping part 210 is pushed open to different degrees (i.e., the clamping position is different), so the angle position of the force-receiving part 220 is also different. The position that the locking member 320 can move to exactly cover all the positions that the force-receiving part 220 can swing to, so that the locking member 320 can abut against the force-receiving part 220.

[0046] During the placement of the cup, the trigger 310 is pushed, causing it to move from the starting position through the critical position and finally to the ending position. As the trigger 310 rotates from the starting position to the critical position, due to the motion coupling between the trigger 310 and the locking member 320, the trigger 310 can drive the locking member 320 to gradually approach the force-receiving part 220. When the trigger 310 reaches the critical position, the locking member 320 abuts against the force-receiving part 220, thus forming a mechanical limit. At this time, the abutting part 210 cannot move past the abutting position and continue to retract.

[0047] It is important to note that the reason for setting a decoupling interval is that the critical position is not a fixed angular position, but rather dynamically changes with the actual angular position of the force-bearing part 220 (i.e., the diameter of the cup). To ensure that the locking member 320 can reliably slide to the position abutting the force-bearing part 220 under any cup diameter, the trigger member 310 must have sufficient travel margin during its retraction, meaning its rotation angle must exceed the critical position under the current operating condition. However, once the locking member 320 has contacted the force-bearing part 220 and formed a mechanical limit, if the trigger member 310 still maintains rigid coupling with the locking member 320, motion interference will occur. Therefore, a decoupling interval must be set after the critical position, so that the trigger member 310 automatically disengages from the locking member 320 after passing the critical position. In this way, the trigger member 310 can continue to retract, while the locking member 320 remains stably maintained in the established limit position.

[0048] It should be noted that the coupling and decoupling of the trigger 310 and the locking member 320 is determined by whether the locking member 320 is in contact with the force-bearing part 220. When the locking member 320 is not in contact, the trigger 310 can drive the locking member 320 to move. When the locking member 320 is in contact, the trigger 310 cannot drive the locking member 320 to continue moving, but the trigger 310 is allowed to drive the locking member 320 to move in the opposite direction, so that the locking member 320 can separate from the force-bearing part 220 (i.e., the trigger 310 returns to the coupling range).

[0049] The locking trigger 300 can mechanically limit the jaws 200 without sacrificing the ease of placing and removing the cups, preventing the jaws 200 from retracting further, thus significantly improving the clamping stability of the jaws 200. Users do not need to perform any additional operations when placing or removing the cups; the locking mechanism is automatically triggered once the cup is in place, completely resolving the contradiction between insufficient clamping force and excessive operating resistance in traditional spring-loaded clamping structures. Because there is a dynamic matching relationship between the sliding position of the locking element 320 and the swing angle of the force-bearing part 220, the cup clamping mechanism can accurately position and effectively limit the cup regardless of its diameter, ensuring that all types of containers are firmly clamped.

[0050] Based on the above implementation method, the critical position is determined by the angular position of the abutting part 210 within the abutting range; when the triggering member 310 rotates from the starting position to the critical position, the displacement of the locking member 320 is inversely proportional to the retraction amount of the abutting part 210.

[0051] The amount of retraction of the clamping part 210 (i.e., the angle traversed by the clamping part 210 from its normal position to its clamping position) is related to the diameter of the cup. When the diameter of the cup is large, the amount of retraction of the clamping part 210 is large, and the rotation angle of the force-receiving part 220 is large. The locking member 320 only needs to slide a small distance to contact the force-receiving part 220. Conversely, when the diameter of the cup is small, the amount of retraction of the clamping part 210 is small, and the rotation angle of the force-receiving part 220 is small. The locking member 320 needs to slide a large distance to contact the force-receiving part 220.

[0052] like Figures 1 to 6 As shown, based on the above embodiment, the claw 200 and the locking trigger 300 are arranged sequentially along the cup insertion direction; during the cup insertion process, the pressing part 210 and the trigger 310 retract sequentially, the force-receiving part 220 first reaches the predetermined angle position, and the locking part 320 then slides to the stroke position that abuts against the force-receiving part 220.

[0053] During the insertion of the cup, the cup wall first contacts and pushes the abutment 210, causing it to retract around the pivot, while the force-receiving part 220 swings to the corresponding position. Subsequently, the cup continues to descend and contacts the trigger 310 of the locking trigger 300, pushing it to rotate. This arrangement determines the sequence of actions: the force-receiving part 220 first reaches the predetermined angle position matching the current cup diameter, and then the trigger 310 begins to drive the locking part 320 to slide, ultimately moving the locking part 320 to a position where it can abut against the force-receiving part 220 at that angle.

[0054] like Figures 1 to 6 As shown, based on the above embodiment, the sliding direction of the locking member 320 in the slide groove 110 is not the same as the swing direction of the force-receiving part 220; a locking inclined surface 221 is provided on the side of the force-receiving part 220 near the locking member 320, the locking inclined surface 221 is inclined relative to the slide groove 110, and when the locking member 320 abuts against the force-receiving part 220, it abuts against the locking inclined surface 221.

[0055] The sliding direction of the locking member 320 within the slide groove 110 is set to vertical, while the swing trajectory of the force-bearing part 220 is an arc trajectory, and the two movement directions are inconsistent. The locking ramp 221 has the characteristic of angle self-adaptation. No matter what angle position the force-bearing part 220 is in, the locking member 320 only needs to slide within its vertical stroke range to abut against the locking ramp 221.

[0056] Based on the above embodiments, when the clamping part 210 is in the clamping range and the trigger 310 is in the decoupling range, the trigger 310 applies a clamping force to the locking ramp 221 through the locking member 320, and the clamping force is converted into a torque acting on the pawl 200 through the locking ramp 221, causing the clamping part 210 to extend. The magnitude of the clamping force increases as the angle of rotation of the trigger 310 toward the end position increases.

[0057] The locking ramp 221 not only serves as a limit, but also decomposes the clamping force applied by the locking member 320 into a torque that resets the pawl 200, thereby causing the clamping part 210 to extend and further press against the outer wall of the cup. Crucially, the magnitude of this clamping force increases with the angle of rotation of the trigger member 310 towards its endpoint; that is, the greater the rotation angle of the trigger member 310, the greater the clamping force exerted by the clamping part 210 on the outer wall of the cup. This positive feedback mechanism enhances the cup clamping capability of the cup clamping mechanism.

[0058] like Figures 1 to 8As shown, based on the above embodiment, a first torsion spring 120 is sleeved on the rotating shaft between the claw 200 and the mounting bracket 100. The two ends of the first torsion spring 120 abut against the claw 200 and the mounting bracket 100 respectively. The first torsion spring 120 applies a torque to the pressing part 210 to make it extend. A second torsion spring 130 is sleeved on the rotating shaft between the trigger member 310 and the mounting bracket 100. The two ends of the second torsion spring 130 abut against the trigger member 310 and the mounting bracket 100 respectively. The second torsion spring 130 applies a torque to the trigger member 310 to make it extend.

[0059] The first torsion spring 120 ensures that the clamping part 210 of the pawl 200 can extend automatically, making it easy to be pushed open when the cup is inserted; the second torsion spring 130 ensures that the trigger 310 automatically rebounds to the starting position after the cup is removed, driving the locking part 320 to reset, releasing the limit on the pawl 200, thereby achieving the purpose of automatic unlocking.

[0060] like Figures 1 to 6 As shown, based on the above embodiment, the locking trigger 300 further includes a connecting rod 330, which is disengaged from the trigger 310. The locking member 320 is hinged to the connecting rod 330. When the trigger 310 is in the coupling range, the torque on the trigger 310 is less than a threshold, and the connecting rod 330 and the trigger 310 are circumferentially locked to make the locking member 320 and the trigger 310 motionally coupled. When the trigger 310 is in the decoupling range, the torque on the trigger 310 is greater than the threshold, and the trigger 310 is allowed to rotate relative to the connecting rod 330 to make the locking member 320 and the trigger 310 motionally decoupled.

[0061] When the trigger 310 is in the coupling zone, the locking member 320 is not in contact with the force-bearing part 220, so the torque on the trigger 310 is small when it rotates. The connecting rod 330 and the trigger 310 are circumferentially locked, so that the torque of the trigger 310 can be effectively transmitted to the locking member 320 through the connecting rod 330, thus achieving motion coupling. When the trigger 310 enters the decoupling zone, the locking member 320 cannot continue to slide because it is blocked by the force-bearing part 220. If the trigger 310 continues to rotate, the torque it bears will exceed the set threshold. The trigger 310 will then rotate relative to the connecting rod 330 (such as slipping or disengaging from the lock), thus achieving motion decoupling.

[0062] Based on the above embodiment, the connecting rod 330 is hinged to the trigger member 310, and a third torsion spring 340 is provided between the connecting rod 330 and the trigger member 310. The two ends of the third torsion spring 340 abut against the connecting rod 330 and the trigger member 310 respectively. The trigger member 310 has an abutment surface 311. When the trigger member 310 is in the coupling range, the connecting rod 330 abuts against the abutment surface 311 under the action of the third torsion spring 340. When the trigger member 310 is in the coupling range and tends to the critical position, the trigger member 310 transmits torque to the connecting rod 330 through the third torsion spring 340. When the trigger member 310 is in the coupling range and tends to the starting position, the trigger member 310 transmits torque to the connecting rod 330 through the abutment surface 311.

[0063] Link 330 is hinged to trigger 310 via a pivot between trigger 310 and mounting bracket 100, i.e., the pivot passes through link 330, trigger 310, and mounting bracket 100. The torque threshold for coupling / decoupling trigger 310 and locking member 320 is determined by third torsion spring 340. When trigger 310 can overcome the torque of third torsion spring 340, it can decouple from locking member 320; otherwise, it is coupled to locking member 320 through third torsion spring 340.

[0064] Within the coupling range, regardless of whether the trigger 310 rotates towards the critical position or the starting position, the torque can be transmitted to the connecting rod 330 through the third torsion spring 340 or the abutment surface 311, thereby driving the locking member 320 to move. However, when the trigger 310 enters the decoupling range, the locking member 320 is blocked by the force-bearing part 220, preventing the connecting rod 330 from moving. If the trigger 310 continues to rotate towards the end position at this time, the trigger 310 will overcome the torque of the third torsion spring 340, thereby rotating freely relative to the connecting rod 330.

[0065] Specifically, when the trigger 310 is in the coupling zone, both the third torsion spring 340 and the abutment surface 311 abut against the connecting rod 330. When the trigger 310 rotates toward the critical position, it drives the connecting rod 330 to rotate via the third torsion spring 340, and when it rotates toward the starting position, it drives the connecting rod 330 to rotate in the opposite direction via the abutment surface 311. During the insertion of the cup, the trigger 310 is pushed to the critical position, and the locking member 320 abuts against the force-receiving part 220. As the cup continues to be inserted, the trigger 310 continues to rotate. At this time, the trigger 310 overcomes the torque of the third torsion spring 340 and rotates relative to the connecting rod 330, and the abutment surface 311 on the trigger 310 separates from the connecting rod 330.

[0066] Based on the above embodiment, the abutting part 210 is provided with an abutting wheel 211 for abutting against the outer wall of the cup. The abutting wheel 211 can roll and contact the outer wall of the cup, reducing the sliding friction when taking the cup out and putting it down, making the cup easier to take out and put down.

[0067] like Figures 1 to 8 As shown, a car cup holder includes at least two cup holder mechanisms and a cup holder body 400. Each cup holder mechanism is installed on the cup holder body 400. The clamping part 210 of the claw 200 of the cup holder mechanism extends into the receiving space of the cup holder body 400, and the trigger 310 of the locking trigger 300 of the cup holder mechanism extends into the receiving space of the cup holder body 400.

[0068] The working process of the car cup holder is as follows: Under the action of the first torsion spring 120 and the second torsion spring 130, both the abutment part 210 and the triggering member 310 are in the extended position (i.e., extended into the receiving space of the cup holder body 400), and the locking member 320 is located at the lower end of the slide groove 110. When the cup is inserted into the receiving space of the cup holder body 400, the abutment part 210 is first pushed and retracted, and the abutment part 210 presses against the outer wall of the cup to achieve initial clamping. At the same time, the force-receiving part 220 swings to an angle position that matches the cup diameter. Subsequently, the cup contacts and pushes the trigger 310, causing it to rotate from its initial position. During rotation, the trigger 310 drives the locking member 320 to slide upward along the slide groove 110 via the connecting rod 330. When the trigger 310 rotates to the critical position, the locking member 320 slides to contact the locking ramp 221 on the force-bearing part 220, thus forming a mechanical limit. Then, the trigger 310 enters the decoupling zone. Since the locking member 320 is blocked by the force-bearing part 220, the connecting rod 330 cannot move. The torque on the trigger 310 increases and eventually overcomes the torque of the third torsion spring 340, allowing the trigger 310 to rotate freely relative to the connecting rod 330 (i.e., the movement of the trigger 310 and the locking member 320 is decoupled). During this process, the trigger 310 applies a greater pressing force to the locking ramp 221. Under the action of the locking ramp 221, this pressing force causes the pressing part 210 to tend to extend. When the cup is removed, the trigger 310 rotates back to the starting position under the action of the second torsion spring 130. The trigger 310 directly pushes the connecting rod 330 through the abutment surface 311. The connecting rod 330 drives the locking member 320 to slide downward, thereby separating from the force-bearing part 220 and releasing the mechanical limit on the claw 200.

[0069] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0070] Furthermore, in this invention, descriptions involving "first," "second," "a," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature.

[0071] In this invention, unless otherwise explicitly specified and limited, the terms "connection" and "fixed" should be interpreted broadly. For example, "fixed" can be a fixed connection, a detachable connection, or an integral part; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal connection of two elements or the interaction between two elements, unless otherwise explicitly limited.

[0072] Furthermore, the technical solutions of the various embodiments of the present invention can be combined with each other, but only if they are feasible for those skilled in the art. If the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by the present invention.

The critical position is located between the starting position and the ending position. The critical position is set as the angular position of the trigger (310) at the instant when the locking member (320) contacts the force-receiving part (220) during the rotation of the trigger (310) from the starting position to the ending position. A coupling interval is formed between the starting position and the critical position, and a decoupling interval is formed between the critical position and the ending position. When the abutting part (210) is in the abutting range and the trigger (310) is in the coupling range, the locking part (320) does not contact the force-receiving part (220), and the locking part (320) and the trigger (310) are kinetically coupled so that the angular position of the trigger (310) determines the stroke position of the locking part (320); When the abutting part (210) is in the abutting range and the trigger (310) is in the decoupling range, the locking part (320) abuts against the force-receiving part (220) to form a mechanical limit that restricts the abutting part (210) from continuing to retract. The locking part (320) and the trigger (310) are decoupled in motion so that the trigger (310) is allowed to rotate freely relative to the locking part (320). During the retraction process, the force-bearing part (220) swings toward the locking member (320); when the trigger member (310) is in the coupling range and rotates toward the critical position, the locking member (320) slides toward the force-bearing part (220).

6. A cup card mechanism as described in claim 1 or 5, characterized in that: A first torsion spring (120) is sleeved on the pivot between the claw (200) and the mounting bracket (100).
