Description

Technical Field

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

[0002] Automotive interior components are a collective term for all parts that make up the interior environment of a car, including the steering wheel, dashboard, and various storage devices. Their core purpose is to enhance driving and passenger comfort, functional convenience, and visual appeal. Among these, cup holders are a very practical and increasingly valued design detail. They are specifically designed to securely and stably hold containers such as water cups and beverage bottles, and are typically located in easily accessible positions such as the center console, front armrest, below the rear air vents, or door panels.

[0003] Chinese patent application CN109109711A discloses a flip-up cup holder structure, which mainly includes a frame mechanism, a main holder mechanism rotatably mounted on the frame mechanism, and a secondary holder mechanism rotatably mounted on the frame mechanism and corresponding to the main holder mechanism. The cup holder has two states: open and closed. The frame mechanism is provided with a locking tongue mechanism that drives the cup holder from the closed state to the open state.

[0004] When the cup holder switches from the open to the closed state, the main tray mechanism rotates to abut against the secondary tray mechanism and drives the secondary tray mechanism to rotate until the main tray mechanism and the locking tongue mechanism cooperate to lock and complete the state switch. Since the secondary tray mechanism is mounted on the frame mechanism, the frame mechanism needs to provide space for the secondary tray mechanism to rotate. However, when the car encounters bumpy roads and the cup holder is open, items or debris can easily fall into the gap of this rotation space. If the driver or passengers are not careful, rotating the main tray mechanism to close it can cause interference with the movement of the secondary tray mechanism, increasing the probability of damage to the cup holder mechanism. Summary of the Invention

[0005] To reduce motion interference when the secondary support mechanism rotates, this application provides a flip-type cup holder.

[0006] The flip-type cup holder provided in this application adopts the following technical solution: A flip-up cup holder includes a frame mechanism, a main support mechanism rotatably mounted on the frame mechanism, a secondary support plate disposed on the frame mechanism, and a locking tongue mechanism locking with the main support mechanism. The secondary support plate has an inner arc surface corresponding to the main support mechanism and for arranging a cup. The secondary support plate is slidably mounted on the frame mechanism. The frame mechanism has a sliding groove for the secondary support plate to slide and arrange, and a secondary support elastic element is provided in the sliding groove to drive the secondary support plate to slide and reset. The sliding groove has a sliding arc surface corresponding to the inner arc surface of the secondary support.

[0007] By adopting the above technical solution, the sub-support plate is slidably installed on the frame mechanism, avoiding the flipping space required by the traditional flip-type sub-support mechanism, reducing the probability of debris falling in and causing motion interference and mechanism damage. The sliding arc surface of the sliding groove matches the inner arc surface of the sub-support, which can make the sub-support plate slide stably and minimize the gap between the sub-support plate and the sliding groove, reducing the probability of small items entering the groove. The elastic element of the sub-support can drive the sub-support plate to slide and reset, ensuring the normal operation of the cup holder.

[0008] Optionally, the auxiliary support elastic element is a conical compression spring, the bottom of the auxiliary support plate is provided with a spring post for one end of the conical compression spring, and the bottom wall of the sliding groove is provided with a spring groove for the other end of the conical compression spring.

[0009] By adopting the above technical solution, using a conical compression spring as the elastic element of the secondary cup holder, and combining the setting of spring column and spring groove, the spring can be accurately positioned to ensure that the secondary cup holder can slide and reset stably and smoothly, avoiding abnormal reset caused by spring displacement, and improving the overall stability of the cup holder.

[0010] Optionally, the side wall of the auxiliary support plate is provided with a limiting block that engages with the skeleton mechanism, and the skeleton mechanism is provided with a limiting groove in the inner wall of the sliding groove for arranging the limiting block.

[0011] By adopting the above technical solution, a limiting block is set on the side wall of the sub-support plate and engages with the skeleton mechanism. The skeleton mechanism is provided with a limiting groove on the inner wall of the sliding groove for the limiting block to be arranged, which can limit the sliding position of the sub-support plate on the skeleton mechanism, making the sub-support plate more stable during the sliding process and reducing the possibility of the sub-support plate shifting or shaking during the sliding process.

[0012] Optionally, the end of the limiting block is provided with an abutting inclined surface for abutting against the inner wall of the sliding groove, and the auxiliary support plate is provided with a deformation relief groove corresponding to the limiting block.

[0013] By adopting the above technical solution, the deformation clearance groove can cause the limiting block to deform to a certain extent when subjected to force, thereby avoiding damage caused by hard collision between the limiting block and the skeleton mechanism, and improving the stability and reliability of the cooperation between the sub-support plate and the skeleton mechanism.

[0014] Optionally, guide ridges are provided on opposite sides of the sub-support plate, and the skeleton mechanism is provided with guide grooves that cooperate with the guide ridges. The sub-support plate is provided with abutting ridges on the side wall of the guide ridges that abut against the inner wall of the guide grooves.

[0015] By adopting the above technical solution, the cooperation between the guide ridge and the guide groove can enhance the stability and smoothness of the sliding of the sub-support plate within the skeleton mechanism. The setting of the abutting ridge abutting against the inner wall of the guide groove reduces the contact area between the sub-support plate and the skeleton mechanism, making the sliding of the sub-support plate smoother.

[0016] Optionally, the main support mechanism is provided with a drive assembly for pushing the sub-support plate. The drive assembly includes a drive frame mounted on the main support mechanism, a drive shaft disposed on the drive frame, and a rotating roller rotatably mounted on the drive shaft. The sub-support plate has a pushing surface for the rotating roller to abut against.

[0017] By adopting the above technical solution, the drive component on the main tray can be used to push the secondary tray, so that the secondary tray moves in a preset manner, ensuring the smooth execution of the cup holder opening and closing action. Compared with the existing technology, sliding friction is converted into rolling friction, reducing the probability of scratches on the top of the secondary tray.

[0018] Optionally, the locking tongue mechanism includes a pressing member slidably mounted on the skeleton mechanism, a locking tongue member locked in cooperation with the main support mechanism, and a return spring for driving the pressing member to reset. The two ends of the return spring abut against the pressing member and the skeleton mechanism respectively. The locking tongue member is limited and mounted on the pressing member, and the sliding of the locking tongue member is realized through the pressing member.

[0019] By adopting the above technical solution, a reset spring is used to replace the existing wire spring to drive the limit lock tongue in conjunction with the push switch to achieve unlocking. The reset force generated is directly applied to the axis of pressing / resetting, resulting in higher mechanical efficiency and a more stable and reliable feel.

[0020] Optionally, the pressing member is provided with a sliding tilting hole, the skeleton mechanism is provided with a sliding translation hole corresponding to the sliding tilting hole, and the locking tongue is provided with a limiting locking pin arranged simultaneously in the sliding tilting hole and the sliding translation hole.

[0021] By adopting the above technical solution, and setting sliding tilting holes, sliding translation holes, and limit locking pins, a stable linkage structure can be formed between the limit locking tongue, the push switch, and the skeleton mechanism, which facilitates the push switch to control the unlocking and locking of the limit locking tongue and the main support mechanism.

[0022] Optionally, there is a sliding gap between the inner arc surface of the secondary tray and the sliding arc surface. The cup tray also includes a collection mechanism for collecting cups that fall into the sliding gap. The collection mechanism includes a collection box disposed at the bottom of the skeleton mechanism and corresponding to the cup body, a collection inclined block slidably installed in the collection box, and a collection elastic element for driving the collection inclined block to reset. The sliding arc surface has a collection through hole through which the collection inclined block passes. The side of the collection inclined block away from the collection box abuts against the bottom of the secondary tray. When the secondary tray moves toward the sliding groove, the collection inclined block slides toward the collection box through the secondary tray.

[0023] By adopting the above technical solution, the collection mechanism can collect items and debris that fall into the sliding gap between the inner arc surface and the sliding arc surface of the secondary tray, preventing debris from affecting the normal sliding of the secondary tray and reducing the probability of damage to the cup holder mechanism.

[0024] Optionally, the skeleton mechanism has a connecting through hole that connects to the collection box, and a rotating plate is rotatably installed in the connecting through hole. A fan is provided on the side of the collection box away from the collection inclined block.

[0025] By adopting the above technical solution, the suction generated by the working of the exhaust fan allows debris to enter the collection box more smoothly through the connecting hole. The rotating plate allows the driver to expose the connecting hole, thus facilitating the cleaning of debris inside the collection box.

[0026] In summary, this application includes at least one of the following beneficial technical effects: This application reduces the probability of motion interference during the movement of the sub-support plate by switching the rotational motion of the sub-support plate to the vertical motion, so that the flipping space does not directly contact the outside world. This application converts sliding friction into rolling friction by setting the drive component, thereby reducing the probability of scratches on the top of the sub-plate; This application, through the setting of a collection mechanism, can collect items and debris that fall into the sliding gap between the arc surface and the sliding arc surface of the sub-support plate, reducing the impact of debris on the normal sliding of the sub-support plate.

[0035] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0036] This application discloses a flip-up cup holder.

[0037] Example 1: Refer to Figure 1 A flip-up cup holder includes a frame mechanism 1, a main support mechanism 2, a secondary support plate 3, and a locking mechanism 4. The frame mechanism 1 is integrally injection molded and is used for fixed connection with the vehicle body. The main support mechanism 2 is rotatably mounted on one side of the frame mechanism 1, and the secondary support plate 3 is slidably mounted on the frame mechanism 1 on the side away from the rotation axis of the main support mechanism 2. The locking mechanism 4 is mounted on the side of the frame mechanism 1 near the secondary support plate 3.

[0038] The cup holder has two states: open and closed. When the cup holder is in the open state, a placement area 21 for placing the cup is formed between the main holder mechanism 2 and the secondary holder plate 3, and the frame mechanism 1 has a placement abutment surface 11 for the cup to rest against. When the cup holder switches from the open state to the closed state, the main holder mechanism 2 rotates towards the secondary holder plate 3 and locks in place with the locking tongue mechanism 4. In the closed state, the main holder mechanism 2 covers the placement area 21, and the secondary holder plate 3 is located entirely below the main holder mechanism 2, making the overall cup holder structure look neat and aesthetically pleasing. A torsion spring is wound around the rotation axis of the main holder mechanism 2 so that when the operator drives the locking tongue mechanism 4 to unlock, the main holder mechanism 2 can automatically open under the action of the torsion spring, thus achieving the state switch.

[0039] The secondary support plate 3 is slidably mounted on the frame mechanism 1 along the height direction. The side of the secondary support plate 3 facing the main support mechanism 2 has an inner arc surface 31 that corresponds to the placement area 21 and abuts against the side wall of the cup. In this embodiment, the secondary support plate 3 has two sets of spaced inner arc surfaces 31. The main support mechanism 2 is provided with a clamping pad 22 for clamping the cup. The clamping pad 22 is rotatably mounted on the main support mechanism 2, and a torsion spring is mounted on the clamping pad 22 to provide clamping force.

[0040] Reference Figure 1 and Figure 2 The frame mechanism 1 has a sliding groove 12 for the sub-support plate 3 to slide up and down. The inner wall of the sliding groove 12 has a sliding arc surface 121 that matches the inner arc surface 31 of the sub-support. There is a sliding gap 122 between the sliding arc surface 121 and the inner arc surface 31 of the sub-support. The sliding gap 122 is between 0.5cm and 1mm. This reduces the contact area between the sub-support plate 3 and the frame mechanism 1, improves the smoothness of sliding, and also reduces the probability of objects entering the sliding groove 12 and causing motion interference.

[0041] The skeleton mechanism 1 is further provided with a secondary support elastic element 32 for lifting and resetting the secondary support plate 3 in the sliding groove 12. In this embodiment, the secondary support elastic element 32 is a conical compression spring. The bottom of the secondary support plate 3 has a spring post 33 for one end of the conical compression spring, and the bottom wall of the sliding groove 12 is provided with a spring groove 123 for the other end of the conical compression spring. The end of the conical compression spring with a larger outer diameter is arranged in the spring groove 123, and the end with a smaller outer diameter is sleeved on the spring post 33.

[0042] Reference Figure 3 and Figure 3 The auxiliary support plate 3 has guide ribs 34 integrally formed on opposite sides along its length, and the inner wall of the sliding groove 12 has guide grooves 124 that slide and cooperate with the guide ribs 34. In order to further reduce the contact area between the auxiliary support plate 3 and the frame mechanism 1, the guide ribs 34 are provided with several abutment ribs 341 on their side walls, and the abutment ribs 341 are used to achieve the abutment between the auxiliary support plate 3 and the inner wall of the guide groove 124.

[0043] The sub-support plate 3 has a limiting block 35 on the guide ridge 34 for installation in conjunction with the frame mechanism 1. The limiting block 35 is a vertically arranged strip-shaped block, including a connecting part 351 and a snap-fit ​​part 352. The connecting part 351 connects the snap-fit ​​part 352 and the guide ridge 34. The frame mechanism 1 has a limiting slide groove 13 that snaps into the snap-fit ​​part 352. The sub-support plate 3 slides up and down within the limiting slide groove 13 via the limiting block 35. The end of the snap-fit ​​part 352 also has an abutting inclined surface 3521 for abutting against the inner wall of the sliding groove 12. The abutting inclined surface 3521 improves the efficiency of the limiting block 35 inserting into the limiting slide groove 13.

[0044] The guide rib 34 also has a deformation clearance groove 342 corresponding to the limiting block 35. The deformation clearance groove 342 penetrates the opposite side walls of the guide rib 34 so that when the sub-support plate 3 is installed, the limiting block 35 can abut and deform towards the sub-support plate 3. When the limiting block 35 and the limiting slide 13 correspond, the limiting block 35 automatically resets and is locked into the limiting slide 13, thereby realizing the installation of the sub-support plate 3 and the frame mechanism 1.

[0045] Reference Figure 2 and Figure 4 To reduce the probability of scratching the top of the auxiliary support plate 3 when the main support mechanism 2 rotates, a drive assembly 23 is installed on the main support mechanism 2. The drive assembly 23 includes a drive frame 231, a drive shaft 232, and rotating rollers 233. The drive frame 231 is inserted into the main support mechanism 2, and the drive frame 231 and the main support mechanism 2 are fixed by welding.

[0046] The drive shaft 232 passes through and is installed in the inner hole of the rotating roller 233, and the drive shaft 232 and the rotating roller 233 are coaxially fixed. The drive frame 231 has a roller groove 2311 for mounting the rotating roller 233, and the main support mechanism 2 has a roller through hole 24 corresponding to the roller groove 2311, allowing the rotating roller 233 to partially protrude from the outer surface of the main support mechanism 2. A rotating groove is formed between the drive frame 231 and the main support mechanism 2 for the end of the drive shaft 232 to be rotatably arranged. In this embodiment, the rotating roller 233 is a rubber-coated roller, which, compared with the prior art of directly pushing the auxiliary support mechanism, transforms sliding friction into rolling friction, reducing the occurrence of friction marks on the top of the auxiliary support plate 3.

[0047] The top of the sub-support plate 3 has a pushing plane 36 corresponding to the drive assembly 23. The pushing plane 36 is located between the inner arc surfaces 31 of the two sets of sub-supports to ensure that the force on the sub-support plate 3 is uniform.

[0048] Reference Figure 5 and Figure 6 The locking mechanism 4 includes a pressing member 41 that is slidably mounted on the frame mechanism 1, a locking member 42 that locks and cooperates with the main support mechanism 2, and a return spring 43 that drives the pressing member 41 to reset.

[0049] The pressing member 41 has a T-shaped cross-section and includes a sliding part and a pressing part. The frame mechanism 1 has a pressing sliding groove 14 for sliding installation of the sliding part. Two sets of first spring grooves (not shown in the figure) are spaced apart at the bottom of the sliding part, and the frame mechanism 1 has a second spring groove (not shown in the figure) corresponding to the first spring grooves at the bottom of the pressing sliding groove 14. The two ends of the return spring 43 are respectively arranged in the first spring groove and the second spring groove. By setting the first spring groove and the second spring groove, the return spring 43 can directly act on the pressing member 41, which has the effect of reducing energy loss and making the structure more compact compared to using a wire spring for reset.

[0050] The pressing member 41 has sliding inclined holes 411 extending through the end faces of both sides of the sliding part. The sliding inclined holes 411 are inclined upward away from the main support mechanism 2. The skeleton mechanism 1 has sliding translation holes 141 arranged in the inner wall of the pressing sliding groove 14, which correspond to the sliding inclined holes 411. The sliding translation holes 141 are arranged in the horizontal direction.

[0051] The locking tongue 42 is integrally arranged inside the pressing member 41, and a limiting locking pin 421 is installed thereon, which is simultaneously arranged in the sliding tilting hole 411 and the sliding translation hole 141.

[0052] The main support mechanism 2 has a locking block 25 that engages with the locking tongue 42. In the closed state, the locking block 25 has a locking groove 251 facing the locking tongue mechanism 4. The locking tongue 42 has a locking part 422 that engages with the locking groove 251. The locking part 422 also has a guide ramp on the side away from the limiting pin, which allows the main support mechanism 2 to be pushed, so that when the main support mechanism 2 is rotated, the locking tongue 42 can be moved by the guide ramp.

[0053] The implementation principle of a flip-type cup holder in this application embodiment is as follows: When it is necessary to adjust the cup holder from the open state to the closed state, the main holder mechanism 2 is rotated toward the auxiliary holder plate 3, the drive component 23 abuts against the push plane 36, and drives the auxiliary holder plate 3 to move vertically downward. The locking block 25 abuts against the locking tongue 42. Under the action of the guide slope, the locking tongue 42 slides horizontally away from the main holder mechanism 2 and along the sliding translation hole 141. At this time, the pressing part 41 descends a certain distance. After the locking groove 251 and the locking tongue 42 correspond, the pressing part 41 automatically resets under the action of the return spring 43. At the same time, the locking tongue 42 is inserted into the locking groove under the action of the sliding tilt hole 411. When it is necessary to adjust the cup holder from the closed state to the open state, press down on the pressing part 41, which will cause the locking tongue 42 to disengage from the locking groove 251 in the horizontal direction. After the locking part 422 disengages from the locking block 25, the main tray mechanism 2 will automatically open under the action of the torsion spring, and the secondary tray 3 will automatically open under the action of the secondary tray elastic part 32.

[0054] Example 2: This example is identical to Example 1 except for the addition of a collection mechanism 5.

[0055] Reference Figure 7 Since there is a certain sliding gap 122 between the inner arc surface 31 of the secondary holder and the sliding arc surface 121, some fine dust or liquid left in the placement gap due to accidental spillage of the cup can still seep into the skeleton mechanism 1 through the sliding gap 122, which may affect the internal structure of the cup holder over a long period of time.

[0056] In this embodiment, a collection mechanism 5 is also installed on the skeleton mechanism 1 to collect dust or liquid that falls into the sliding gap 122. The collection mechanism 5 includes a collection box 51, a collection ramp 52, and a collection elastic member 53.

[0057] The collection box 51 is located entirely below the placement contact surface 11, and has storage space inside. The collection box 51 is fixed to the frame mechanism 1 by bolts. The frame mechanism 1 has a connecting through hole 111 on the placement contact surface 11 that connects to the collection box 51, and a rotating plate 112 is rotatably installed in the connecting through hole 111. The rotating plate 112 corresponds to the collection box 51, so that the driver can open the rotating plate 112 to periodically empty the garbage in the collection box 51.

[0058] The collecting inclined block 52 is installed at an angle on the side of the collecting box 51 near the auxiliary support plate 3. The frame mechanism 1 has a collecting through hole 1211 on the sliding arc surface 121 that penetrates both end faces. The collecting inclined block 52 partially passes through the collecting through hole 1211, and the length of the collecting through hole 1211 in the height direction is greater than the thickness of the collecting inclined block 52. The collecting inclined block 52 abuts against the collecting abutment part 521 at the bottom of the auxiliary support plate 3 on the side away from the collecting box. The collecting inclined block 52 has a collecting inclined surface 522 to guide dust or liquid to slide off.

[0059] The collection box 51 has limiting slides 54 on opposite sides, which are arranged at an angle. The collecting inclined block 52 has limiting sliders 523 on opposite sides of the limiting slides 54. The bottom of the collecting inclined surface 522 is located below the limiting sliders 523 to reduce the probability of dust or liquid entering the limiting slides 54. The collecting elastic element 53 is a spring, with its two ends abutting against the bottom of the limiting slides 54 and the ends of the limiting sliders 523, respectively.

[0060] When the sub-support plate 3 moves downward, it drives the collecting inclined block 52 to slide vertically downward. Under the combined action of the limiting slider 523 and the limiting slide rail 54, the collecting inclined block 52 moves tilted along the limiting slide rail 54, causing the collecting inclined block 52 to gradually detach from the sliding groove 12. A small exhaust fan 55 is also installed on the outer wall of the collecting box 51 away from the collecting inclined block 52. The exhaust fan 55 is connected to the vehicle's power supply, and air is drawn into the exhaust fan from the gap between the collecting inclined block 52 and the placement contact surface 11.

[0061] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
