Description

Technical Field

[0001] The present invention relates to the technical field of vehicles, and in particular to an armrest assembly and a vehicle having the same. Background Art

[0002] An armrest is a key component of a car's interior, typically located between the driver's and passenger's seats, on the center console. It provides elbow support for the driver and passengers, enhancing the user experience. It can also cover storage boxes on the center console, preventing them from being exposed and enhancing the interior's aesthetics and privacy.

[0003] Armrests in the prior art generally include various types, such as rear-folding, roller-curtain, split-leaf, and double-opening. Among them, double-opening armrests can be flipped left or right according to actual needs, allowing users to easily open the storage box from both the driving position and the co-pilot position. For example, Chinese utility model patent CN214775628U discloses an armrest that can be pressed sideways to open from both sides. The armrest includes a mounting frame, on which a flip cover with a mounting cavity is slidably arranged. A first flip limit assembly and a second flip limit assembly with retractable ends on both sides are arranged in the mounting cavity, and a flip member with a first rotation point and a second rotation point is arranged in the mounting frame. One telescopic end of the first flip limit assembly passes through the first rotation point and extends into the mounting frame, while the other telescopic end extends into the mounting frame. The second telescopic end of the second flip limit assembly extends into the flip member and is close to the second rotation point, while the other telescopic end extends into the mounting frame. Through the above arrangement, the armrest can be opened from both sides, making it convenient for people on both sides of the armrest to use it.

[0004] In addition, this utility model defines the positions of the first and second flip-limiting assemblies by providing first and third clamping portions on the drive plates corresponding to the first and second flip-limiting assemblies, and providing corresponding second and fourth clamping portions on the bottom cover of the flip cover to prevent them from rebounding. Several horizontally arranged clamping blocks are also provided on the drive plate, defining a slot for accommodating an elastic rod. An extension of the drive plate is provided with a first and second outwardly protruding mounting block. One end of the elastic rod extends through the first mounting block and into the second mounting block, imparting a downward restoring force to the extension. A mounting shell and a lifting block are also fixed to the underside of the mounting frame, with two ejector pins fixed to the upper end of the lifting block. These two ejector pins are positioned to mate with the third clamping portion to lift the extension on the drive plate, thereby separating the mutually engaged clamping portions. However, the structure of this armrest is relatively complex, and both manufacturing feasibility and structural stability could be improved.

[0005] Therefore, this field needs a new technical solution to solve the above problems. Summary of the Invention

[0006] In order to improve or, to a certain extent, resolve the technical problem of the complex structure of armrest assemblies in the prior art, the present invention provides an armrest assembly. The armrest assembly comprises: a storage box; a cover body fixed to the storage box; an unlocking mechanism disposed on the cover body and configured to release the cover body so that it can be flipped relative to the storage box, the unlocking mechanism being provided with a locking groove; and a locking mechanism comprising a locking rod rotatably fixed within the cover body, the locking rod abutting against the unlocking mechanism and applying a preload force thereto, wherein the locking groove is positioned such that when the unlocking mechanism slides relative to the locking rod until the locking groove reaches below the locking rod, the locking rod can fall into the locking groove under the action of the preload force to lock the unlocking mechanism.

[0007] The armrest assembly of the present invention includes a storage box, a lid, an unlocking mechanism, and a locking mechanism. The storage box can hold items to meet the user's storage needs. The lid is fixed to the storage box, preventing the storage space from being exposed, enhancing the aesthetics and privacy, while also providing elbow support for the user, improving the riding experience. The unlocking mechanism is arranged on the lid and configured to flip the lid relative to the storage box by releasing it, allowing the user to easily open the lid and access items. The locking mechanism includes a locking rod rotatably fixed within the lid. The locking rod abuts against the locking mechanism and applies a preload pressure to it. The unlocking mechanism is also provided with a locking groove, which is positioned so that when the unlocking mechanism slides relative to the locking rod until it reaches below the locking rod, the locking rod, under the action of the preload pressure, falls into the locking groove, thereby locking the unlocking mechanism. This arrangement provides the armrest assembly of the present invention with a simple and stable structure, thereby reducing manufacturing costs and extending service life.

[0008] In a preferred embodiment of the armrest assembly, the cover comprises a base plate and a top cover formed on the base plate, with a cavity formed between the base plate and the top cover to accommodate the unlocking and locking mechanisms. This arrangement allows the unlocking and locking mechanisms to be located within the cavity between the base plate and the top cover, preventing them from being exposed. This aesthetically pleasing design also protects the components, extending their service life.

[0009] In a preferred embodiment of the armrest assembly, the locking mechanism includes an elastic member; the locking lever has a fixed end rotatably fixed to the base plate, and the elastic member is disposed on the fixed end to apply the preload force to the unlocking mechanism via the locking lever, causing the locking lever to abut against the unlocking mechanism. Providing the elastic member on the fixed end of the locking lever facilitates applying preload force to the unlocking mechanism, causing the locking lever to abut against the unlocking mechanism, thereby improving structural stability.

[0010] In a preferred embodiment of the armrest assembly, the locking lever has a movable end opposite the fixed end, and a locking protrusion is provided between the fixed and movable ends, extending vertically downward from the locking lever and capable of being received in the locking groove. Providing the locking protrusion between the fixed and movable ends, which is capable of being received in the locking groove, allows the locking lever to more easily engage with the locking groove.

[0011] In a preferred embodiment of the armrest assembly, a stopper protrusion extending away from the fixed end is provided on the movable end, and a stopper post is provided on the base plate to mate with the stopper protrusion. By providing the stopper protrusion on the movable end and the stopper post on the base plate to mate with the stopper protrusion, the position of the locking lever during rotation can be limited, further improving the stability of the component.

[0012] In a preferred technical solution of the above-mentioned armrest assembly, a reset protrusion extending vertically downward from the locking rod is further provided on the movable end; a through-hole is provided on the base plate to allow the reset protrusion to pass therethrough; and an elastic protrusion is provided on the storage box to match the reset protrusion. When the cover is closed on the storage box, the elastic protrusion abuts against the reset protrusion and lifts the locking rod, causing the locking protrusion to disengage from the locking groove and release the unlocking mechanism. The cooperation between the reset protrusion on the locking rod and the elastic protrusion on the storage box facilitates lifting the locking rod, thereby disengaging the locking protrusion from the locking groove and releasing the unlocking mechanism. In addition, the provision of the reset protrusion and the elastic protrusion can further simplify the structure and reduce the difficulty of processing. Furthermore, when the cover is closed on the storage box, the unlocking mechanism is released and reset. The elastic protrusions and reset protrusions that abut each other not only make the structure more stable, but the setting of the elastic protrusions can also have a shock-absorbing effect, thereby improving the NVH performance of the component.

[0013] In the preferred technical solution of the above-mentioned armrest assembly, the armrest assembly further includes: a flip mechanism, the flip mechanism includes a first rotating shaft and a second rotating shaft that are spaced apart from each other along the width direction of the cover body and are both retractable, the unlocking mechanism includes a first unlocking mechanism matched with the first rotating shaft and a second unlocking mechanism matched with the second rotating shaft, and the locking mechanism includes a first locking mechanism matched with the first unlocking mechanism and a second unlocking mechanism matched with the second unlocking mechanism. Through the above-mentioned arrangement, the user can conveniently control the cover body to flip around the corresponding second rotating shaft and the first rotating shaft through the first unlocking mechanism and the second unlocking mechanism according to actual needs, thereby realizing the function of opening the storage box in both directions. In addition, the arrangement of the first locking mechanism and the second locking mechanism can also facilitate locking the corresponding first unlocking mechanism and the second unlocking mechanism to ensure the stability of the structure.

[0014] In a preferred technical solution of the above-mentioned armrest assembly, the armrest assembly further includes a combination lock mechanism, comprising: a control member rotatably fixed within the cover body, the control member having a first end and a second end extending through a base plate of the cover body, and a third end located between the first end and the second end; and a first push rod and a second push rod, the first push rod and the second push rod being located outside the storage box and configured to abut against the first end and the second end, respectively, so that the third end is positioned between the first unlocking mechanism and the second unlocking mechanism to limit relative movement of the first unlocking mechanism and the second unlocking mechanism. The provision of the combination lock mechanism can improve the anti-theft performance of the armrest assembly of the present invention.

[0015] In a preferred embodiment of the armrest assembly, the armrest assembly further comprises a buffer mechanism comprising: a first buffer member and a second buffer member, each of the first buffer member and the second buffer member being fixed to the rear of the storage box and spaced apart from each other along the width direction, each of the first buffer member and the second buffer member having a buffer head facing the cover; and a first clamping head and a second clamping head, each of the first clamping head and the second clamping head being arranged at the rear of the cover, each of the first clamping head and the second clamping head having an arc-shaped groove for clamping the corresponding buffer head. This arrangement allows the cover to be turned more smoothly during flipping, thereby improving the product's service life and user experience.

[0016] To improve or, to a certain extent, resolve the technical problem of complex armrest assembly structures in the prior art, the present invention provides a vehicle. The vehicle includes an armrest assembly according to any of the above-described embodiments. By employing any of the above-described armrest assemblies, the vehicle of the present invention can streamline the product structure, optimize the product design, reduce manufacturing costs, and enhance the user experience.

The positions of the first through hole 214a and the second through hole 214b are respectively opposite to the first elastic protrusion 1212a and the second elastic protrusion 1212b corresponding to the front end 121 of the upper box body 12 of the storage box 10, so that the reset protrusion 4132 on the corresponding locking rod 41 in the locking mechanism 40 can pass through the through hole 214 and cooperate with the corresponding elastic protrusion 1212. The first through hole 214a and the second through hole 214b can be waist holes, circular holes or other suitable through holes. In one or more embodiments, a boss (not shown in the figure) extending vertically upward from the upper surface of the substrate 21 is formed at the edges of the first through hole 214a and the second through hole 214b to enhance the mechanical strength and rigidity near the through hole 214.

[0051] Continue to see Figure 11 In one or more embodiments, a third through-hole 215 and a fourth through-hole 216 are further provided on the front portion of the base plate 21, spaced apart from each other in the left-right direction. The third through-hole 215 and the fourth through-hole 216 are symmetrically arranged between the first through-hole 214a and the second through-hole 214b. In the assembled state, the third through-hole 215 opposes the first through-hole 1213 at the front end 121 of the upper housing 12 of the storage box 10, allowing the first push rod 611 of the combination lock mechanism 60 to pass through the first through-hole 1213 and the third through-hole 215, respectively, and then mate with the first end 621 of the control member 62 of the combination lock mechanism 60. Correspondingly, in the assembled state, the fourth through-hole 216 opposes the second through-hole 1214 at the front end 121 of the upper housing 12 of the storage box 10, allowing the second push rod 612 of the combination lock mechanism 60 to pass through the second through-hole 1214 and the fourth through-hole 216, respectively, and then mate with the second end 622 of the control member 62.

[0052] Continue to see Figure 11 In one or more embodiments, a retaining post 217 is further provided on the front portion of the base plate 21. The retaining posts 217 include a first retaining post 217a and a second retaining post 217b spaced apart in the left-right direction. Each of the first retaining post 217a and the second retaining post 217b defines a retaining opening (not shown) extending in the vertical direction and opening rearward to receive a retaining protrusion 4131 on the corresponding retaining rod 41 of the locking mechanism 40.

[0053] Continue to see Figure 11In one or more embodiments, a fifth through-hole 218a and a sixth through-hole 218b are further provided on the front portion of the base plate 21, spaced apart from each other in the left-right direction and facing rearward. In the assembled state, the fifth through-hole 218a is opposite the first front axle hole 1211a at the front end 121 of the upper body 12 of the storage box 10, allowing the first front axle 512 of the flip mechanism 50 to pass through the fifth through-hole 218a and be inserted into the first front axle hole 1211a. Correspondingly, in the assembled state, the sixth through-hole 218b is opposite the second front axle hole 1211b at the front end 121 of the upper body 12 of the storage box 10, allowing the second front axle 522 of the flip mechanism 50 to pass through the sixth through-hole 218b and be inserted into the second front axle hole 1211b.

[0054] Continue to see Figure 11 In one or more embodiments, a first locking rod fixing bracket 219a and a second locking rod fixing bracket 219b are further provided in the middle portion of the base plate 21, spaced apart from each other in the left-right direction. The first locking rod fixing bracket 219a mates with the first locking rod 41a in the locking mechanism 40, rotatably securing the first locking rod 41a to the base plate 21 about a rotation axis extending in the left-right direction. The second locking rod fixing bracket 219b mates with the second locking rod 41b in the locking mechanism 40, rotatably securing the second locking rod 41b to the base plate 21 about a rotation axis extending in the left-right direction.

[0055] Figure 7 1 is a first structural schematic diagram of an embodiment of an unlocking mechanism, a locking mechanism, and a flipping mechanism in an armrest assembly of the present invention; Figure 8 is a second structural schematic diagram of an embodiment of the unlocking mechanism, the locking mechanism and the flipping mechanism in the armrest assembly of the present invention; Figure 9 Schematic diagram of the structure of the embodiment of the unlocking mechanism, locking mechanism, flip structure and control member in the armrest assembly of the present invention. Figure 5 、 Figure 7-Figure 9As shown, in one or more embodiments, the flip mechanism 50 includes a first rotating shaft 51, a second rotating shaft 52, and a connecting rod 53 disposed between the first rotating shaft 51 and the second rotating shaft 52. Both ends of the first rotating shaft 51 (the first front shaft body 512 and the first rear shaft body 515, respectively) can be inserted into the corresponding shaft holes of the storage box 10 (the first front shaft hole 1211a and the first rear shaft hole 1221, respectively), so that the cover body 20 can flip around the axis where the first front shaft body 512 and the first rear shaft body 515 are located. In addition, the two ends of the second rotating shaft 52 (respectively, the rear ends of the second front axle body 522 and the second rear slide bar 524) can be respectively inserted into the second front axle hole 1211b of the storage box 10 and the second rear slide bar limiting hole 5311 of the connecting rod 53, and a second rear axle body 5321 matching the second front axle body 522 is also provided on the connecting rod 53 fixed at one end to the storage box 10, so that the cover body 20 can be flipped around the axis where the second front axle body 522 and the second rear axle body 5321 are located at the same time.

[0056] Continue to see Figure 7-Figure 9 The first rotating shaft 51 includes a first front sliding bar 511 and a first rear sliding bar 514 spaced apart from each other in the front-to-back direction, and a first elastic connector 513 interposed between the first front sliding bar 511 and the first rear sliding bar 514. The first front sliding bar 511 and the first rear sliding bar 514 are formed by injection molding using a suitable resin material (e.g., ABS). The first elastic connector 513 is a spring or other suitable elastic member, which allows the first front sliding bar 511 and the first rear sliding bar 514 to be retractably fixed to the base plate 21.

[0057] Continue to see Figure 7-Figure 9The first front sliding bar 511 has a body extending generally in the front-to-back direction. A first front guide head 5111 extending vertically upward is formed on the body of the first front sliding bar 511. The first front guide head 5111 is generally cylindrical in shape and can be inserted into a corresponding first guide hole 3311 on the first transmission plate 33a of the unlocking mechanism 30. Furthermore, a first front limiting protrusion 5112 is provided on each left and right side of the body of the first front sliding bar 511. Each first front limiting protrusion 5112 is configured to mate with a corresponding first front limiting post 211a on the base plate 21, restricting the first front sliding bar 511 to sliding only in the front-to-back direction. The number and placement of the first front limiting protrusions 5112 can be adjusted as needed, as long as they mate with the first front limiting post 211a. A first front axle body 512 is also provided at the front end of the first front sliding bar 511, which is generally L-shaped and extends forward. The first front axle 512 can be made of a suitable metal material such as stainless steel to ensure its mechanical strength. In the assembled state, the first front slide bar 511 is pre-thrusted by the first elastic connector 513, so that the first front axle 512 passes through the corresponding fifth perforation 218a on the base plate 21 and is inserted into the first front axle hole 1211a of the box body 12 on the storage box 10. When the first transmission plate 33a moves to the right, the first front guide head 5111 slides in the first guide hole 3311 of the first transmission plate 33a, thereby causing the first elastic connector 513 to contract under the action of an external force. During this process, the first front slide bar 511 is controlled to move backward, thereby driving the first front axle 512 to disengage from the first front axle hole 1211a.

[0058] Continue to see Figure 7-Figure 9The first rear sliding bar 514 has a body extending generally in the front-to-back direction. A first rear guide head 5141 extending vertically upward is formed on the body of the first rear sliding bar 514. The first rear guide head 5141 is generally cylindrical in shape and can be inserted into the corresponding second guide hole 3312 on the first transmission plate 33a. Furthermore, a plurality of first rear limiting protrusions 5142 are spaced apart from each other on the left and right sides of the body of the first rear sliding bar 514. Each first rear limiting protrusion 5142 is configured to mate with a corresponding first rear limiting post 211b on the base plate 21, thereby restricting the first rear sliding bar 514 to sliding only in the front-to-back direction. The number and placement of the first rear limiting protrusions 5142 can be adjusted as needed, as long as they mate with the first rear limiting post 211b. A first rear axle 515 is also provided at the rear end of the first rear sliding bar 514, which is generally L-shaped and extends rearward. The first rear axle 515 can be made of a suitable metal material, such as stainless steel, to ensure its mechanical strength. When assembled, the first rear slide bar 514 is preloaded with thrust by the first elastic connector 513, causing the first rear axle 515 to sequentially pass through the first rotating shaft fixing rod 517, the first booster spring 516, and the movable end 533 of the connecting rod 53, and then be inserted into the first rear axle hole 1221 of the rear end 122 of the upper body 12 of the storage box 10. When the first transmission plate 33a moves rightward, the first rear guide head 5141 slides within the second guide hole 3312 of the first transmission plate 33a, causing the first elastic connector 513 to contract under the action of an external force. During this process, the first rear slide bar 514 is controlled to slide forward, thereby driving the first rear axle 515 out of the first rear axle hole 1221. Furthermore, when the first front axle 512 is inserted into the first front axle hole 1211a, the first rear axle 515 is inserted into the first rear axle hole 1221, and the second rotating shaft 52 is controlled to be disengaged from the storage box 10, the entire cover 20 can flip around the axis of the first front axle 512 and the first rear axle 515. It should be noted that the main body of the first rotating shaft fixing plate 517 is provided with a plurality of spaced-apart engaging holes (not labeled in the figure), each of which can form a snap fit with a corresponding engaging post (not labeled in the figure) on the base plate 21 to improve the stability and firmness of the connection between the base plate 21 and the first rotating shaft 51, thereby driving the entire cover 20 to flip smoothly. In addition, the first assist spring 516 is configured to apply a pre-loaded elastic force to the cover 20, so that when the second rotating shaft 52 is controlled to be disengaged from the storage box 10, the pre-loaded elastic force can drive the cover 20 to flip smoothly.

[0059] like Figure 7-Figure 9As shown, the second rotating shaft 52 includes a second front sliding bar 521 and a second rear sliding bar 524 spaced apart from each other in the front-to-back direction, and a second elastic connector 523 interposed between the second front sliding bar 521 and the second rear sliding bar 524. The second front sliding bar 521 and the second rear sliding bar 524 are made of a suitable resin material (e.g., ABS, etc.) through an injection molding process. The second elastic connector 523 is a spring or other suitable elastic member, which allows the second front sliding bar 521 and the second rear sliding bar 524 to be retractably fixed to the base plate 21.

[0060] Continue to see Figure 7-Figure 9 The second front sliding bar 521 has a body extending generally in the front-to-back direction. A second front guide head 5211 extending vertically upward is formed on the body of the second front sliding bar 521. The second front guide head 5211 is generally cylindrical in shape and can be inserted into the corresponding first guide hole 3311 on the second transmission plate 33b of the unlocking mechanism 30. Furthermore, a second front limiting protrusion 5212 is provided on each left and right side of the body of the second front sliding bar 521. Each second front limiting protrusion 5212 is configured to mate with a corresponding second front limiting post 211c on the base plate 21, restricting the second front sliding bar 521 to sliding only in the front-to-back direction. The number and placement of the second front limiting protrusions 5212 can be adjusted as needed, as long as they mate with the second front limiting post 211c. A second front axle 522 is also provided at the front end of the second front sliding bar 521, which is generally L-shaped and extends forward. The second front axle 522 can be made of a suitable metal material such as stainless steel to ensure its mechanical strength. In the assembled state, the second front slide bar 521 is pre-thrusted by the second elastic connector 523, causing the second front axle 522 to pass through the corresponding sixth perforation 218b on the base plate 21 and be inserted into the second front axle hole 1211b of the box body 12 on the storage box 10. When the second transmission plate 33b moves to the left, the second front guide head 5211 slides in the first guide hole 3311 of the second transmission plate 33b, causing the second elastic connector 523 to contract under the action of an external force. During this process, the second front slide bar 521 is controlled to move backward, thereby driving the second front axle 522 to disengage from the second front axle hole 1211b.

[0061] Continue to see Figure 7-Figure 9The second rear sliding bar 524 has a body extending generally in the front-to-back direction. A second rear guide head 5241 extending vertically upward is formed on the body of the second rear sliding bar 524. The second rear guide head 5241 is generally cylindrical in shape and can be inserted into the corresponding second guide hole 3312 on the second transmission plate 33b. Furthermore, a plurality of second rear limiting protrusions 5242 are provided on the left and right sides of the body of the second rear sliding bar 524, spaced apart from each other. Each second rear limiting protrusion 5242 is configured to mate with a corresponding second rear limiting post 211d on the base plate 21, thereby restricting the second rear sliding bar 524 to sliding only in the front-to-back direction. The number and arrangement of the second rear limiting protrusions 5242 can be adjusted according to actual needs, as long as they can mate with the second rear limiting post 211d. In the assembled state, the second rear slide bar 524 is preloaded by the second elastic connector 523, causing its rear end to be inserted into the corresponding second rear slide bar stop hole 5311 on the connecting rod 53. When the second transmission plate 33b moves leftward, the second rear guide head 5241 slides within the second guide hole 3312 of the second transmission plate 33b, causing the second elastic connector 523 to contract under the external force. During this process, the second rear slide bar 524 is controlled to move forward, causing its rear end to disengage from the second rear slide bar stop hole 5311.

[0062] Continue to see Figure 7 and Figure 8The connecting rod 53 includes a connecting rod body 531 extending generally in the left-right direction. In one or more embodiments, the connecting rod body 531 is formed from a suitable resin material (e.g., ABS) through an injection molding process. Alternatively, the connecting rod body 531 may be formed from a suitable metal material such as aluminum or stainless steel. A second rear slider retaining hole 5311 opening forward is formed in the connecting rod body 531 to mate with the rear end of the second rear slider 524. In one or more embodiments, the connecting rod body 531 includes a fixed end 532 on the right side and a movable end 533 on the left side. Alternatively, the fixed end 532 may be located on the left side of the connecting rod body 531, and the movable end 533 may be located on the right side of the connecting rod 531. Accordingly, the first rotating shaft 51 is located on the right side of the base plate 21, and the second rotating shaft 52 is located on the left side of the base plate 21. A second rear axle body 5321 extending rearward is provided on the fixed end 532. The second rear axle body 5321 may be made from a suitable metal material such as stainless steel to ensure mechanical strength. It should be noted that the second rear axle 5321 is configured to be rotatably fixed to the connecting rod fixing bracket 54, and the connecting rod fixing bracket 54 is fixed in the connecting rod fixing groove 1222 of the rear end 122 of the box body 12 of the storage box 10. A second booster spring 5322 is also sleeved on the second rear axle 5321. Through the above arrangement, when the second front axle 522 is inserted into the second front axle hole 1211b and the first rotating shaft 51 is controlled to be disengaged from the storage box 10, the entire cover body 20 can flip around the axis between the second front axle 522 and the second rear axle 5321. In addition, a through hole (not shown in the figure) is provided on the movable end 533 to allow the first rear axle 515 to pass through it, so that the first rear axle 515 can be easily matched with the first rear axle hole 1221 and can also drive the connecting rod 531 to rotate around the second rotating shaft 52.

[0063] like Figure 5-Figure 9As shown, in one or more embodiments, the unlocking mechanism 30 includes components such as an unlocking button 31, a button housing 32, a transmission plate 33, and a return spring 34. The button housing 32 includes a first button housing 32a and a second button housing 32b that are fixed to the substrate 21 in a bilaterally symmetrical manner. The unlocking button 31 includes a first unlocking button 31a and a second unlocking button 31b that are respectively arranged on the first button housing 32a and the second unlocking button 31b. The transmission plate 33 includes a first transmission plate 33a and a second transmission plate 33b that are spaced apart from each other in the left-right direction. The first transmission plate 33a is configured to match the first unlocking button 31a so that pressing the first unlocking button 31a can drive the first transmission plate 33a to slide to the right. Correspondingly, the second transmission plate 33b is configured to match the second unlocking button 31b so that pressing the second unlocking button 31b can drive the second transmission plate 33b to slide to the left. In addition, the return spring 34 includes a first return spring 34a matched with the first transmission plate 33a and a second return spring 34b matched with the second transmission plate 33b, so as to facilitate the return of the first transmission plate 33a and the second transmission plate 33b.

[0064] Continue to see Figure 9 In one or more embodiments, the first transmission plate 33a includes an outer plate 331 and an inner plate 332 that are connected to each other. The outer plate 331 is provided with a first guide hole 3311 and a second guide hole 3312 that are spaced apart from each other in the front-to-back direction. The first guide holes 3311 and the second guide holes 3312 are arranged in a roughly figure-eight shape. That is, the spacing between the first guide holes 3311 and the second guide holes 3312 gradually increases from left to right. The first guide hole 3311 is configured to receive the first front guide head 5111 on the first front sliding bar 511, and the second guide hole 3312 is configured to receive the first rear guide head 5141 on the first rear sliding bar 514. With the above arrangement, when the first transmission plate 33a slides rightward under the drive of the first unlocking button 31a, the cooperation between the guide head and the guide hole enables the first front slider 511 and the first rear slider 514 to slide toward each other and compress the first elastic connector 513 located between the first front slider 511 and the first rear slider 514. During this process, the first front axle body 512 fixed to the first front slider 511 is disengaged from the first front axle hole 1211a, and the first rear axle body 515 fixed to the first rear slider 514 is disengaged from the first rear axle hole 1221.

[0065] Continue to see Figure 9In one or more embodiments, the inner plate body 332 is a roughly rectangular plate-like structure. The plate-like structure is configured to match the multiple transmission plate limiting columns 212 located on the front and rear sides of the base plate 21, so that the entire first transmission plate 33a is constrained to slide only in the left and right directions. A roughly rectangular return spring accommodating hole 3322 is formed in the middle of the inner plate body 332, so that the first return spring 34a can be constrained in the return spring accommodating hole 3322. Specifically, a return spring fixing column 3323 extending vertically to the right is formed on the left hole wall of the return spring accommodating hole 3322. The return spring fixing column 3323 is configured to match the corresponding first return spring limiting column 213a (see Figure 11 ), so that one end of the first return spring 34a is fixed to the return spring fixing post 3323 and the other end is fixed to the first return spring limiting post 213a. Therefore, when the first transmission plate 33a slides rightward under the influence of the first unlocking button 31a, the first return spring 34a is compressed. When the external force is removed, the first return spring 34a rebounds under its own stress, thereby causing the first transmission plate 33a and the first unlocking button 31a to return to their original position.

[0066] Continue to see Figure 9 A vertically upwardly extending circumferential protrusion 3321 is formed on the circumferential edge of the inner plate 332 to enhance the rigidity and strength of the inner plate 332. Preferably, the vertically upwardly extending circumferential protrusion 3321 is provided along the entire circumferential edge of the first transmission plate 33a (including the outer plate 331 and the inner plate 332). A generally rectangular locking groove 3321 is formed on the circumferential protrusion 3321 near the front of the inner plate 332 to mate with the corresponding first locking lever 41a on the locking mechanism 40.

[0067] It should be noted that the second transmission plate 33b is configured to be arranged bilaterally symmetrically with the first transmission plate 33a, which will not be described in detail here.

[0068] Figure 10 FIG is a schematic structural diagram of an embodiment of the locking mechanism in the armrest assembly of the present invention. Figure 5 、 Figure 7-10 As shown, the locking mechanism 40 includes a locking rod 41 and an elastic member 42. The locking rod 41 includes a first locking rod 41a and a second locking rod 41b spaced apart in the left-right direction. The first locking rod 41a is compatible with the first transmission plate 33a, and the second locking rod 41b is compatible with the second transmission plate 33b. The elastic member 42 includes a first elastic member 42a compatible with the first locking rod 41a and a second elastic member 42b compatible with the second locking rod 41b. Preferably, the first locking rod 41a and the second locking rod 41b are configured identically, and the first elastic member 42a and the second elastic member 42b are also configured identically to simplify the component structure and facilitate processing.

[0069] Continue to see Figure 10 The locking rod 41 has a rod body 411 extending roughly in the front-to-back direction. The rod body 411 can be made of a suitable resin material (such as ABS, etc.) through an injection molding process. In one or more embodiments, the rod body 411 has a roughly rectangular longitudinal cross-section. Alternatively, the longitudinal cross-section of the rod body 411 can also be set to a square or other suitable shape. In one or more embodiments, a locking protrusion 4111 extending vertically downward from the lower surface of the rod body 411 is formed in the middle of the rod body 411. The locking protrusion 4111 has a large rectangular shape so as to match the locking groove 33211 on the corresponding transmission plate 33. Through the cooperation of the locking protrusion 4111 and the locking groove 33211, the transmission plate 33 can be easily locked, thereby achieving the locking of the corresponding unlocking structure 30. Alternatively, the locking protrusion 4111 may not be provided on the rod body 411, as long as the longitudinal cross-section of the rod body 411 can match the locking groove 33211 so that the locking rod 41 can fall into the locking groove 33211. In one or more embodiments, a reinforcing protrusion 4112 is further formed on the rod body 41, extending vertically upward from its upper surface, to enhance the rigidity and strength of the rod body 411.

[0070] It should be noted that when the locking lever 41 and the locking groove 33211 cooperate to lock the corresponding transmission plate 33, the opposing transmission plates 33 (i.e., the first transmission plate 33a and the second transmission plate 33b) approach and abut against each other, further realizing the anti-opening function. For example, when the first unlocking button 31a is pressed, causing the first transmission plate 33a to slide rightward, the first locking lever 41a and the first transmission plate 33a slide relative to each other, causing the locking protrusion 4111, which originally rested on the circumferential protrusion 3321, to fall into the locking groove 33211. At this time, the right vertical surface (not shown) of the first transmission plate 33a moves toward the left vertical surface (not shown) of the second transmission plate 33b and abuts against each other, preventing the second transmission plate 33b from sliding leftward by pressing the second unlocking button 31b. Through the above arrangement, it is possible to prevent the entire cover 20 from being separated from the storage box 10 due to pressing the unlocking buttons 31 on both sides at the same time.

[0071] Continue to see Figure 10The rod body 411 has a fixed end 412 close to the rear side and a movable end 413 close to the front side. The fixed end 412 is rotatably fixed to the first locking rod fixing bracket 219a or the second locking rod fixing bracket 219b corresponding to the base plate 21, so that the locking rod 41 can rotate along the axis extending in the left and right directions. An elastic member 42 is provided on the fixed end 412 to apply a downward pre-load pressure to the locking rod 41 so that the locking rod 41 can be stably abutted against the transmission plate 33. In one or more embodiments, a limiting protrusion 4131 extending in a direction away from the fixed end 412 is formed on the movable end 413. The limiting protrusion 4131 is configured to be inserted into the limiting column 217 (including the first limiting column 217a and the second limiting column 217b) corresponding to the base plate 21 to limit the position of the locking rod 41.

[0072] Figure 12 Schematic diagram of the partial structure of the embodiment of the armrest assembly of the present invention in which the reset protrusion is inserted into the through hole. Figure 10 and Figure 12 As shown, in one or more embodiments, a reset protrusion 4132 extending vertically downward from the lower surface of the rod body 411 is further provided on the movable end 413. The reset protrusion 4132 is configured to pass through the corresponding through hole 214 on the base plate 21. When the cover body 20 is closed on the storage box 10, the reset protrusion 4132 passing through the through hole 214 can abut against the corresponding elastic protrusion 1212 on the upper box body 12. Then, the elastic protrusion 1212 will apply an upward external force to the reset protrusion 4132, causing the locking rod 41 to be lifted and rotated around the fixed end 412 under the action of the lever. During this process, the locking protrusion 4111 that falls into the locking groove 33211 moves upward with the locking rod 41 and disengages from the locking groove 33211, thereby releasing the corresponding unlocking mechanism 30.

[0073] Figure 13 1 is a schematic structural diagram of an embodiment of an armrest assembly of the present invention in which a control member is arranged on a top cover; Figure 14 FIG is a schematic diagram of the structure of an embodiment of the control member in the armrest assembly of the present invention. Figure 1 、 Figure 2 、 Figure 5 、 Figure 9 、 Figure 13 and Figure 14 As shown, in one or more embodiments, the combination lock mechanism 60 includes an electric push rod 61 fixed to the front end of the lower box body 11 of the storage box 10, a control member 62 rotatably fixed on the top cover 22 of the cover body 20, and a control member return spring 63 arranged on the control member 62 and other components.

[0074] Continue to see Figure 2The electric push rod 61 has a first push rod 611 and a second push rod 612 that are spaced apart from each other in the left-right direction and are retractable. The first push rod 611 and the second push rod 612 have a generally cylindrical shape. The first push rod 611 can sequentially pass through the first through-hole 1213 in the upper housing 12 and the third through-hole 215 in the base plate 21, and mate with the first end 621 of the control member 62. Correspondingly, the second push rod 612 can sequentially pass through the second through-hole 1214 in the upper housing 12 and the fourth through-hole 216 in the base plate 21, and mate with the second end 622 of the control member 62.

[0075] Continue to see Figure 13 and Figure 14 The control member 62 has a first end 621 and a second end 622 spaced apart from each other in the left-right direction, and a third end 623 disposed between the first end 621 and the second end 622. The control member return spring 63 is configured to apply an upward thrust to the control member 62, causing the third end 623 to be away from the first transmission plate 33a and the second transmission plate 33b in the initial state. When the first push rod 611 and the second push rod 612 apply an upward thrust to the first end 621 and the second end 622, respectively, the third end 623 moves downward under the action of the lever and is positioned between the first transmission plate 33a and the second transmission plate 33b. As a result, the first unlock button 33a and the second unlock button 33b are simultaneously locked. In other words, the cover 20 cannot be opened by pressing the first unlock button 33a and the second unlock button 33b, thereby enhancing the privacy of the entire armrest assembly 1. Accordingly, when the first push rod 611 and the second push rod 612 are controlled to move downward and disengage from the corresponding first end 621 and the second end 622, the third end 623 moves upward and resets under the drive of the control member reset spring 63, thereby contacting the restrictions on the first unlocking button 33a and the second unlocking button 33b.

[0076] like Figure 1 、 Figure 3 、 Figure 4 and Figure 11 As shown, in one or more embodiments, the buffer mechanism 70 includes a first buffer member 71a and a second buffer member 71b fixed to the upper box body 12 of the storage box 10, and a first clamping head 72a and a second clamping head 72b formed on the base plate 21. The first buffer member 71a and the second buffer member 71b are arranged at the rear end 122 of the upper box body 12 in a left-right direction and spaced apart from each other. Each of the first buffer member 71a and the second buffer member 71b is a cylindrical damper and has a buffer head 711 extending toward the front.

[0077] Continue to see Figure 11, the first clamp 72a and the second clamp 72b are arranged at intervals along the left-right direction at the rear of the base plate 21. Each of the first clamp 72a and the second clamp 72b is configured to extend vertically backward from the vertical surface (not marked in the figure) at the rear of the base plate 21, and to form an arc-shaped groove 721 opening downward. The provision of the arc-shaped groove 721 can conveniently and stably clamp the buffer head 711 on the corresponding buffer member (i.e., the first buffer member 71a and the second buffer member 71b). By providing a buffer mechanism on the armrest assembly 1, the flipping process of the cover body 20 can be made smoother.

[0078] The present invention further provides a vehicle (not shown). The vehicle includes the armrest assembly 1 described in any of the above embodiments. The armrest assembly 1 is disposed on the center console of the vehicle, i.e., positioned between the driver's seat and the passenger seat. The vehicle can be an electric vehicle, a gasoline-powered vehicle, or other suitable vehicle.
