Description
Technical Field
[0001] This invention relates to the field of vehicle technology, and more particularly to armrest assemblies and vehicles having them. Background Technology
[0002] Vehicles in the current technology typically feature a foldable armrest in the center area of the rear seats, allowing users to stow and unfold it as needed. When the armrest is stowed, the rear seat space is fully utilized; when unfolded, users can easily use it to support their elbows, improving the user experience. A headrest is usually also provided at the top of the armrest to ensure user comfort and safety.
[0003] To enhance the functionality of armrests, existing technologies have developed armrests that also function as cup holders. For example, Chinese utility model patent CN210258134U discloses a rear center armrest headrest structure with a cup holder. This rear center armrest headrest mechanism includes a headrest and a cup assembly, which is concealed within the headrest. The cup assembly can be unlocked from the headrest via an unlock button, and then the user can pull the cup holder assembly out of the headrest by grasping the front panel of the cup holder. Once the cup holder assembly is pulled out, the cup tray and cup holder panel on the cup assembly cooperate to clamp and limit the cup. However, in this rear center armrest headrest mechanism, the cup assembly is located inside the headrest, which limits the depth at which the cup can be clamped, resulting in poor clamping effect. In addition, because the cup assembly occupies part of the internal space of the headrest, the space originally used to arrange headrest components to ensure its comfort and safety is squeezed, thus reducing the comfort and safety of the headrest accordingly.
[0004] Therefore, a new technical solution is needed in this field to solve the above problems. Summary of the Invention
[0005] To improve or partially solve the technical problems of poor cup-holding effect and poor comfort and safety of headrests in existing technologies, the present invention provides an armrest assembly. The armrest assembly is configured to hold a cup and includes: an armrest body having a cavity and an opening communicating with the cavity; a headrest rotatably fixed to the end of the armrest body near the opening, and having a cup slot on the back of the headrest for placing the cup; and a cup holder mechanism having a cup holder bracket disposed within the cavity, and the cup holder bracket being popped out from the opening to hold the cup.
[0006] The armrest assembly of this invention includes an armrest body, a headrest, and a cup holder mechanism. The armrest body has a cavity and an opening communicating with the cavity. The headrest is rotatably fixed to the end of the armrest body near the opening, allowing the headrest to be adjusted in angle to meet storage and placement requirements. A cup holder is provided on the back of the headrest, not only conveniently placing a cup and enhancing the headrest's functionality, but also concealing the cup holder when the headrest is not in use, preventing it from being exposed and affecting aesthetics. The cup holder mechanism has a cup holder bracket arranged within the cavity, configured to pop out from the opening to hold a cup. Through the above arrangement, the cup holder and the cup holder mechanism are respectively arranged on the headrest and the armrest body. On one hand, the relative position of the cup holder and the cup holder mechanism can be easily adjusted to increase the depth of cup holding and ensure a secure grip; on the other hand, it prevents excessive occupation of the headrest's internal space, ensuring the headrest's comfort and safety.
[0007] In the preferred embodiment of the above-described armrest assembly, the headrest includes: a housing; and a rod mechanism, the rod mechanism including a crossbar extending along the width direction of the housing and fixed within the housing, and a first rod and a second rod extending parallel from both ends of the crossbar into the cavity. The crossbar is configured to rotate relative to the first rod and the second rod, allowing the headrest to rotate relative to the armrest body by a predetermined angle. The crossbar is fixed within the headrest housing, and its rotatability relative to the first and second rods allows it to not only be fixed to the armrest body but also to rotate easily relative to it. Furthermore, the height of the headrest on the armrest body can be adjusted by the cooperation of the first and second rods to meet the user's personalized needs.
[0008] In the preferred embodiment of the above-mentioned armrest assembly, the headrest further includes an unlocking mechanism, which comprises a first ratchet and a second ratchet. The first ratchet is sleeved on the crossbar, and the second ratchet is rotatably fixed within the housing. When the second ratchet abuts against the first ratchet, the headrest is locked; and when the second ratchet disengages from the first ratchet, the headrest is unlocked. The interaction between the first and second ratchets facilitates locking and unlocking of the headrest.
[0009] In the preferred embodiment of the above-described handrail assembly, the unlocking mechanism further includes a fixed bracket, which is fixed within the housing and has a through hole allowing the unlocking rod to pass through. The second ratchet and the transmission component are rotatably fixed to the fixed bracket. The fixed bracket ensures stable and effective cooperation between the unlocking rod, the transmission component, and the second ratchet, thereby improving structural stability.
[0010] In the preferred embodiment of the above-described handrail assembly, the transmission member has a force-receiving end that matches the unlocking lever and a force-applying end spaced apart from the force-receiving end. When the force-receiving end is subjected to a force applied by the unlocking lever, the force-applying end can abut against the second ratchet to disengage the second ratchet from the first ratchet. Through this arrangement, the external force received by the unlocking button can be conveniently transmitted to the second ratchet, thereby achieving the mutual engagement of the second and first ratchets.
[0011] In the preferred embodiment of the above-mentioned handrail assembly, the predetermined angle ranges from 50° to 60°. This setting ensures that the predetermined angle has a suitable range to meet the design requirements for storage and placement.
[0012] In the preferred embodiment of the above-described armrest assembly, the cup holder mechanism further includes a cover plate and a base plate that are opposite to each other and fixed within the cavity, and the cover plate and the base plate together form an inner cavity that allows the cup holder support to slide therein. With this arrangement, the cup holder support can easily slide within the inner cavity formed by the cover plate and the base plate, facilitating transitions between an idle state and a working state.
[0013] In the preferred embodiment of the aforementioned armrest assembly, the cup holder includes: a support body, with U-shaped grooves on both sides of the support body, each capable of accommodating a cup and having an outward-facing opening; and claws, the claws engaging with the corresponding U-shaped grooves to define a receiving space for accommodating the cup, and when the cup is placed within the receiving space, the claws abut against the cup and apply a predetermined pressure thereon. By providing outward-facing U-shaped grooves on the support body, cups can be easily received. Furthermore, the claws prevent the cup from detaching from the U-shaped grooves, improving the stability of the clamping mechanism.
[0014] In the preferred embodiment of the above-mentioned armrest assembly, a vertically downward extending guide rod is formed at the lower part of each of the claws, and a guide groove matching the corresponding guide rod is provided on the base plate. The cooperation between the guide rod and the guide groove ensures the relative position of the claws when the entire cup holder slides within the inner cavity, preventing misalignment of the claws during sliding.
[0015] In the preferred embodiment of the above-described armrest assembly, a vertically upward extending limiting post is formed on the upper surface of the support body; a limiting member is provided on the cover plate, and a limiting protrusion and an escape groove surrounding the limiting protrusion are formed on the limiting member. The limiting protrusion can abut against the limiting post to constrain the cup holder bracket within the inner cavity, and the limiting post can slide along the escape groove and disengage from the limiting protrusion to unlock the cup holder bracket. Through the cooperation of the limiting post and the limiting protrusion, the cup holder bracket can be easily constrained within the inner cavity. Furthermore, through the cooperation of the limiting post and the escape groove, the cup holder bracket can be easily unlocked.
[0016] In the preferred embodiment of the above-described handrail assembly, a slider extending along the sliding direction of the support body is provided on the lower surface of the support body, and a groove for receiving the slider is provided on the base plate. This arrangement makes the support body more stable during sliding.
[0017] In the preferred embodiment of the above-mentioned handrail assembly, a plurality of guide rails spaced apart from each other along a direction perpendicular to the sliding direction are further provided on the lower surface of the support body, and guide protrusions that match the corresponding guide rails are provided on the base plate. Through the above-mentioned arrangement, the sliding stability of the support body can be further improved.
[0018] In the preferred embodiment of the above-mentioned handrail assembly, a buffer gear is further provided on the lower surface of the support body, and a buffer rack that can mate with the buffer gear is provided on the base plate. The cooperation between the buffer gear and the buffer rack can make the sliding process of the support body smoother, thereby improving the user experience.
[0019] In the preferred embodiment of the above-described armrest assembly, a plurality of rollers are provided on the side of the support body away from the opening, spaced apart from each other and rotatably fixed to the support body. The cup holder mechanism further includes a force-applying coil spring, which has a first end fixed to the rollers and a second end fixed to the base plate near the opening. When the cup holder is unlocked from the inner cavity, the spring itself automatically pops out without requiring the user to drag it, thus improving the user experience.
[0020] To improve or partially solve the technical problems of poor cup-holding effect of armrest components and poor comfort and safety of headrests in existing technologies, the present invention provides a vehicle. This vehicle includes the armrest component described in any of the above claims. By employing the armrest component described in any of the above claims, the vehicle of the present invention can increase the depth of cup holding, ensuring a holding effect, while simultaneously ensuring the comfort and safety of the headrest.

[0089] To improve or partially solve the technical problems of poor cup-holding effect of existing armrest components and poor comfort and safety of headrests, the present invention provides an armrest component 100. The armrest component 100 is configured to hold a cup 200 and includes: an armrest body 10, with a cavity 12 and an opening 13 communicating with the cavity 12 within the armrest body 10; a headrest 20, rotatably fixed to the end of the armrest body 10 near the opening 13, and having a cup groove 2121 for placing a cup 200 on its back 212; and a cup holder mechanism 30, the cup holder mechanism 31 having a cup holder bracket 34 disposed within the cavity 12, and the cup holder bracket 34 being popped out from the opening 13 to hold the cup 200.
[0090] Figure 1 This is a schematic diagram of an embodiment of the handrail assembly of the present invention in an idle state; Figure 2 This is a schematic diagram of an embodiment of the handrail assembly of the present invention in its working state; Figure 3 This is a schematic diagram of an embodiment of the armrest assembly of the present invention for holding a cup. Figures 1-3As shown, in one or more embodiments, the armrest assembly 100 of the present invention includes components such as an armrest body 10, a headrest 20, and a cup holder mechanism 30. The armrest body 10 is adapted to be rotatably fixed to the middle area of a rear seat (not shown) of a vehicle. The armrest body 10 has an armrest housing 11. The armrest housing 11 has opposing fixed ends 111 and movable ends 112. The fixed ends 111 are rotatably fixed to the rear seat, and the movable ends 112 can rotate around the fixed ends 111 by a set angle, allowing the armrest body 10 to switch between an "idle position" against the rear seat and a "working position" away from the rear seat. In one or more embodiments, the set angle is 108°. Alternatively, the set angle may be set to other suitable angles larger or smaller than 108°. A cavity 12 is formed inside the armrest housing 11 and near the movable ends 112 to accommodate the cup holder mechanism 30. An opening 13 communicating with the cavity 12 is provided on the movable end 112, so that the cup holder support 34 of the cup holder mechanism 30 can pop out through the opening 13 to hold the cup 200.
[0091] like Figures 1-3 As shown, in one or more embodiments, the headrest 20 is rotatably fixed to the movable end 112 of the armrest body 10. The headrest 20 has a housing 21. The housing 21 is made up of components such as a cover, foam, and a plastic frame to ensure the comfort and safety of the headrest 20. In the assembled state, the housing 21 has a front 211 away from the rear seat and a back 212 facing the rear seat. A cup holder 2121 extending vertically inward is formed on the back 212. When the armrest body 10 is in the idle position, the back 212 of the housing 21 rests against the rear seat, effectively covering the cup holder 2121 and preventing it from being exposed and affecting the aesthetics. When the armrest body 10 is in the working position, by adjusting the angle of the headrest 20, the back 212 of the housing 21 can face approximately upwards of the vehicle, allowing the cup 200 to be placed approximately horizontally in the cup holder 2121 to realize its function of holding items. In one or more embodiments, an anti-slip pad (not shown in the figure) is also provided at the bottom of the cup groove 2121 to increase the friction between the cup 200 and the cup groove 2121.
[0092] Figure 4 This is a schematic diagram of the internal structure of the headrest in an embodiment of the armrest assembly of the present invention. (See diagram below.) Figure 4 As shown, in one or more embodiments, the headrest 20 has a insertion rod mechanism 22. The insertion rod mechanism 22 includes a crossbar 221, a first insertion rod 222, and a second insertion rod 223. The crossbar 221 is fixed inside the housing 21 and is generally along the width direction of the housing 21 (based on...).

The crossbar 221 can be made of resin material (e.g., ABS, PP, etc.), metal material (e.g., stainless steel, aluminum alloy, etc.) or other suitable material. The first insertion rod 222 and the second insertion rod 223 are respectively arranged at both ends of the crossbar 221 and extend into the cavity 12 of the armrest body 10, so that the headrest 20 and the armrest body 10 form a fixed connection. The first insertion rod 222 and the second insertion rod 223 can be made of suitable metal material such as stainless steel or aluminum alloy to ensure their mechanical strength. In one or more embodiments, the height of the first insertion rod 222 and the second insertion rod 223 within the armrest body 10 is adjustable, so that the user can adjust the height of the headrest 20 according to actual needs to meet personalized needs. In addition, the crossbar 221 is configured to rotate relative to the first insertion rod 222 and the second insertion rod 223, so that the headrest 20 and the armrest body 10 can rotate at a predetermined angle. In one or more embodiments, the predetermined angle is in the range of 50°-60°, so that the predetermined angle has a moderate range to meet the process design requirements for storage and placement.

[0094] Figure 7 This is a second structural schematic diagram of an embodiment of the unlocking structure for removing the fixing bracket in the handrail assembly of the present invention. (See diagram below.) Figures 4-7 As shown, in one or more embodiments, the headrest 20 includes an unlocking structure 23. The unlocking structure 23 includes components such as an unlocking button 231, a fixing bracket 232, a transmission component 233, a first ratchet 234, and a second ratchet 235. Alternatively, the unlocking structure 23 may employ other suitable structures.
[0095] See also Figures 4-7The unlock button 231 is retractably fixed to the housing 21 of the headrest 20. In one or more embodiments, the unlock button 231 is located on the left side of the housing 21. Alternatively, the unlock button 231 may also be arranged on the right side of the housing 21. The unlock button 231 includes a pressing end 2311, an unlocking lever 2312 formed on the pressing end 2311, and a button return spring 2313 sleeved on the unlocking lever 2312. The unlocking lever 2312 extends from the inside of the pressing end 2311 toward the interior of the housing 21, and its extension direction is generally parallel to the width direction of the housing 21. When the user presses the pressing end 2311, the unlocking lever 2312 is driven to move toward the interior of the housing 21, thereby applying a force to the transmission member 233 of the unlocking mechanism 23. When the external force applied to the pressing end 2311 is removed, the unlock button 231 can rebound and reset under the action of the button return spring 2313.
[0096] See also Figure 4 and Figure 5 The fixed bracket 232 is fixed inside the housing 21, and the transmission component 233 and the second ratchet 235 are fixed to the fixed bracket 232 at intervals, making the structure of the entire unlocking mechanism 23 more compact. The fixed bracket 232 can be made of suitable metal materials such as stainless steel or aluminum alloy, giving it good mechanical strength. A through hole 2321 is provided on the fixed bracket 232 to allow the unlocking rod 2312 to pass through it for mating with the transmission component 233. The fixed bracket 232 also has through holes 2322 spaced apart from the through hole 2321, allowing the crossbar 221 to pass through the fixed bracket 2322.
[0097] See also Figures 4-7 The transmission component 233 is rotatably fixed to the fixed bracket 232. The transmission component 233 can be made of suitable metal materials such as stainless steel or aluminum alloy to give it good mechanical strength. Based on Figure 4As shown, the transmission member 233 has a force-receiving end 2331 extending generally vertically and perpendicular to the width direction of the housing 21, allowing the unlocking lever 2312 to easily abut against the force-receiving end 2331. The transmission member 233 also has a force-applying end 2332 extending downward from the body of the transmission member 233 to apply external force to the second ratchet 235. In one or more embodiments, the transmission member 233 is further provided with a limiting end 2333 spaced apart from the force-receiving end 2331 and the force-applying end 2332. The limiting end 2333 is configured to abut against the fixed bracket 232 to define the initial position of the transmission member 233. In one or more embodiments, protective sleeves 236 are fitted onto both the force-applying end 2332 and the limiting end 2333, forming a flexible connection between the transmission member 233 and the fixed bracket 232, and between the transmission member 233 and the second ratchet 235. The protective cover 236 can be made of suitable materials such as rubber or plastic. Additionally, the transmission component 233 has a transmission component rotation shaft 2334 fixed to the fixed bracket 232 and extending approximately perpendicular to the back surface 212 of the housing 21. When the force-bearing end 2331 is subjected to an external force from the unlocking lever 2312, the transmission component 233 rotates counterclockwise around the rotation shaft 2334 under the action of a lever (based on...). Figure 4 (The aforementioned orientation). During this process, the force-applying end 2332 moves downward, thereby applying an external force to the second ratchet 235. When the external force from the unlocking lever 2312 is removed, the transmission component 233 is configured to rotate clockwise around the rotation axis 2334 under its own gravity (based on...). Figure 4 (as shown in the diagram), and abut against the fixed bracket 232 (i.e., return to the initial position), thereby resetting the transmission component 233.
[0098] See also Figures 4-7The first ratchet 234 is sleeved on the crossbar 221 and fixedly connected to it. The first ratchet 234 can be made of a suitable metal material such as stainless steel to give it good mechanical strength. A generally arc-shaped first abutment surface 2341 is formed on the top of the first ratchet 234 to mate with the second abutment surface 2352 on the second ratchet 235. Specifically, when the first abutment surface 2341 abuts against the second abutment surface 2352, the first ratchet 234 and the second ratchet 235 are locked together, and the crossbar 221 cannot rotate smoothly; when the second abutment surface 2352 disengages from the first abutment surface 2341, the first ratchet 234 and the second ratchet 235 are unlocked, and the crossbar 221 can rotate smoothly relative to the first insert 222 and the second insert 223. The first ratchet 234 also has a first limiting end 2342 and a second limiting end 2343 spaced apart from each other. The first limiting end 2342 and the second limiting end 2343 can respectively abut against corresponding positions of the fixed bracket 232 to limit the initial position and rotational position of the first ratchet 234. In one or more embodiments, protective sleeves 236 are provided on the corresponding positions of the fixed bracket 232 that abut against the first limiting end 2342 and the second limiting end 2343, so that a flexible connection is formed between the fixed bracket 232 and the first limiting end 2342 and the second limiting end 2343, preventing the first ratchet 234 from damaging the components during rotation.
[0099] See also Figures 4-7 The second ratchet 235 is rotatably fixed within the fixed bracket 232. The second ratchet 235 can be made of a suitable metal material such as stainless steel to give it good mechanical strength. The second ratchet 235 has a force-receiving surface 2351 opposite to the force-applying end 2332 of the transmission member 233, allowing the force-applying end 2332 to easily apply external force to the second ratchet 235. A generally arc-shaped second abutment surface 2352 is also formed at the bottom of the second ratchet 235 to mate with the first abutment surface 2341 on the first ratchet 234. The second ratchet 235 has a second ratchet rotation shaft 2353 fixed to the fixed bracket 232 and extending generally along the width direction of the housing 21. With the above configuration, when the transmission component 233 is subjected to a force from the unlocking lever 2312, the force-applying end 2332 of the transmission component 233 applies a corresponding force to the force-receiving surface 2351 of the second ratchet 235, causing the second ratchet 235 to rotate around the second ratchet rotation axis 2353. During this process, the second abutting surface 2352 and the first abutting surface 2341, which are abutting each other, disengage from each other and gradually move away from each other, thereby unlocking the first ratchet 234 and the second ratchet 235.
[0100] See also Figures 5-7A return spring 237 is also fitted onto the crossbar 221. The return spring 237 has a first end 2371 fixed to the bottom of the fixed bracket 232 and a position fixed to the first ratchet 234 near the first limiting end 2342. With the above arrangement, the crossbar 221 can be easily reset by the stress of the return spring 237 itself after rotation.
[0101] See also Figures 4-5 In one or more embodiments, a toothed plate 24 spaced apart from the first ratchet 234 is also sleeved on the crossbar 221, and a damper 25 that can mate with the toothed plate 24 is also fixed inside the housing 21. The cooperation between the toothed plate 24 and the damper 25 can make the rotation of the headrest 20 smoother.
[0102] Figure 8 This is a schematic diagram of an embodiment of the cup holder mechanism in the armrest assembly of the present invention; Figure 9 This is an exploded view of an embodiment of the cup holder mechanism in the armrest assembly of the present invention. (See attached image.) Figure 8 and Figure 9 As shown, in one or more embodiments, the cup holder mechanism 30 includes components such as a cover plate 31, a base plate 32, and a cup holder support 34. The cover plate 31 and the base plate 32 are fixed within the cavity 12 of the armrest body 10, and are arranged opposite to each other to form an inner cavity 33 that allows the cup holder support 34 to slide within it. In one or more embodiments, the cover plate 31 and the base plate 32 are connected by six spaced-apart fasteners 36. The fasteners 36 can be screws, bolts, etc. Alternatively, the number of fasteners can be set to more or less than six in other suitable ways. Alternatively, the cover plate 31 and the base plate 32 can also be fastened by snap-fit or other suitable methods.
[0103] See also Figure 8 and Figure 9 The cover plate 31 has a generally plate-shaped cover plate body 311. The cover plate body 311 can be integrally molded from a suitable resin material such as ABS or PP through an injection molding process. A limiting member 312 is arranged on the cover plate body 311. The limiting member 312 is configured to mate with the limiting post 3413 on the cup holder bracket 34 to achieve locking and unlocking of the cup holder bracket 34. Figure 10 This is a structural schematic diagram of an embodiment of the limiting member and limiting post in the handrail assembly of the present invention. (See attached diagram.) Figure 10As shown, in one or more embodiments, a limiting protrusion 3121 extending vertically downward from its lower surface is formed on the limiting member 312. In the assembled state, the limiting protrusion 3121 has a U-shaped limiting groove 31211 facing away from the opening 13. The U-shaped limiting groove 31211 is configured to receive the limiting post 3413 to lock the cup holder 34. In addition, the limiting member 312 is also provided with an escape groove 3122 surrounding the limiting protrusion 3121, so that when the cup holder 34 is subjected to external force, the limiting post 3413 can disengage from the U-shaped limiting groove 31211 and separate from the limiting protrusion 3121 along the escape groove 3122, thereby unlocking the cup holder 34.
[0104] Figure 11 This is a structural schematic diagram of an embodiment of the base plate in the handrail assembly of the present invention. For example... Figure 8 , Figure 9 , Figure 11 As shown, in one or more embodiments, the base plate 32 has a generally plate-shaped base plate body 321. The base plate body 321 can be integrally molded from a suitable resin material such as ABS or PP using an injection molding process. In one or more embodiments, a sliding direction along the cup holder support 34 is formed in the middle of the base plate body 32 (based on...). Figure 11 A groove 322 extending in the indicated direction (i.e., the front-to-back direction) is provided to mate with a slider 3414 on the cup holder support 34. In one or more embodiments, a buffer rack 325 spaced apart from the groove 322 is provided in the middle of the base plate body 32. The buffer rack 325 extends generally along the sliding direction of the cup holder support 34 and mates with a buffer gear 3416 on the cup holder support 34. In one or more embodiments, guide protrusions 323 extending generally along the sliding direction of the cup holder support 34 are provided on the left and right sides of the base plate body 32. Each guide protrusion 323 can mate with a corresponding guide rail 3415 on the cup holder support 34. In one or more embodiments, guide grooves 324 spaced apart from the guide protrusions 323 are also provided on the left and right sides of the base plate body 32. Each guide groove 324 is configured to mate with a guide rod 34221 arranged on the claw 342 of the cup holder support 34. In addition, near the opening 13, each guide groove 324 has a flared guide opening (not shown in the figure), which allows the guide rod 34221 to be easily inserted into the corresponding guide groove 324, thereby allowing the pop-out claw 342 to be easily stored in the inner cavity 33.
[0105] Figure 12 This is a front structural schematic diagram of an embodiment of the cup holder bracket in the armrest assembly of the present invention; Figure 13 This is a schematic diagram of the rear structure of an embodiment of the cup holder bracket in the armrest assembly of the present invention. (See diagram below.) Figure 12 and Figure 13As shown, in one or more embodiments, the cup holder support 34 includes a support body 341 and claws 342 arranged on the left and right sides of the support body 341. The support body 341 can be integrally molded from a suitable resin material such as ABS or PP using an injection molding process. A pressing rod 3411 that can mate with the opening 13 is formed at one end of the support body 341. Based on Figure 13 As shown, the pressing rod 3411 extends approximately in the left-right direction. The pressing rod 3411 allows the user to easily apply external force to the support body 341, causing it to pop out of the inner cavity 343. U-shaped grooves 3412 with outward openings are formed on the left and right sides of the support body 341 near the pressing rod 3411 to receive the cup 200. The support body 341 has opposing upper surfaces 341a and lower surfaces 341b. In the assembled state, the upper surface 341a faces the cover plate 31, and the lower surface 341b faces the base plate 32. A vertically upward extending limiting post 3413 is formed at the center of the upper surface 341a, at one end away from the pressing rod 3411. The limiting post 3413 has a generally cylindrical shape to mate with the limiting member 312 located on the cover plate 31.
[0106] See also Figure 13 In one or more embodiments, a vertically outwardly extending slider 3414 is formed on the lower surface 341b of the support body 341. The slider 3414 is located in the middle of the lower surface 341b and extends approximately along the sliding direction of the cup holder support 34. The slider 3414 is inserted into the groove 322 of the base plate 32 to constrain the sliding direction of the cup holder support 34. Alternatively, the number of sliders 3414 can also be multiple, such as two or three, as long as they can match the corresponding grooves 322 on the base plate 32. In one or more embodiments, two guide rails 3415 are also provided on the lower surface 341b, located on the left and right sides respectively. Each guide rail 3415 can receive a corresponding guide protrusion 323 on the base plate 32 to further improve the sliding stability of the cup holder support 34. Alternatively, the number of guide rails 3415 can also be set to more or less than two other suitable numbers, as long as they can match the guide protrusions 323 on the base plate 32. In one or more embodiments, a buffer gear 3416 is rotatably fixed on the lower surface 341b of the support body 341 so as to match the buffer rack 325 on the base plate 32, so that the cup holder support 34 slides more smoothly in the inner cavity 33 (especially when it pops out from the inner cavity 33).
[0107] See also Figure 9 and Figure 13In one or more embodiments, rollers 3417 are provided on the left and right sides of the end of the bracket body 341 away from the pressing rod 3411. Each roller 3417 is rotatably fixed to the bracket body 341, and the axis of rotation of each roller 3417 extends approximately in the left-right direction (based on...). Figure 13 (As shown in the diagram). Additionally, the cup holder mechanism 30 includes a force-applying coil spring 35 that mates with the roller 3417, allowing the cup holder support 34 to automatically pop out of the inner cavity 33 under the elastic force of the force-applying coil spring 35 after unlocking. Specifically, each force-applying coil spring 35 extends approximately along the sliding direction of the cup holder support 34. Each force-applying coil spring 35 also has a first end 351 and a second end 352. The first end 351 is fixed to the corresponding roller 3417, and the second end 352 is fixed to the base plate 32 near the opening 13.
[0108] See also Figure 12 and Figure 13 In one or more embodiments, the claws 342 are arranged on the left and right sides of the support body 341 and respectively mate with the corresponding U-shaped grooves 3412 to form a receiving space 343 for clamping the cup 200. Each claw 342 includes components such as a claw body 3421, a claw connecting rod 3422, and a clamping spring 3423. The claw body 3421 has a generally arcuate shape and extends into the corresponding U-shaped groove 3412. The claw body 3421 is rotatably fixed to the claw connecting rod 3422 so that cups of different sizes can be clamped by rotating the claw 3421. The claw connecting rod 3422 is fixed on the lower surface 341b of the support body 341. In one or more embodiments, a guide rod 34221 extending vertically outward is formed at the lower part of the claw connecting rod 3422. The guide rod 34221 has a generally cylindrical shape to mate with the guide groove 324 on the base plate 32, so that the claw 342 has a stable relative position when sliding together with the support body 341. The clamping spring 3423 is arranged between the claw body 3421 and the claw connecting rod 3422, and the clamping spring 3423 is configured to apply a predetermined elastic force to the claw 342 when the claw 342 rotates under the action of external force and engages with the corresponding U-shaped groove 3412 to clamp the cup 200, thereby causing the claw 342 to apply a predetermined pressure to the cup 200 to firmly and stably clamp the cup 200.
