Description

Technical Field

[0001] This application relates to the field of vehicle handrail technology, and more particularly to a handrail box and a vehicle. Background Technology

[0002] The armrest box is usually located between the driver's seat and the front passenger seat in a vehicle. The armrest box can be used by the driver or front passenger to place their arms and support their elbows. At the same time, the armrest box also has a storage function to increase the vehicle's storage space.

[0003] For the side-flip armrest box in a vehicle, pressing the unlock buttons on both sides allows the armrest to flip open, making it convenient for both the driver and front passenger to use simultaneously. In related technologies, armrest boxes are difficult to open from only one side, and opening from both sides simultaneously would cause inconvenience for users. Utility Model Content

[0004] This application provides an armrest box and a vehicle to at least partially solve the problem in the related art that armrest boxes are difficult to open from one side.

[0005] To achieve the above objectives, according to a first aspect of this application, an armrest box is provided, comprising: a base, an armrest, and a gear unlocking mechanism. The base has a limiting hole, and the armrest is disposed on the base. The gear unlocking mechanism is connected to the base and the armrest, and includes two unlocking components disposed opposite to each other. Each unlocking component includes: an unlocking rack, an unlocking gear, and a rotating shaft. The unlocking rack meshes with the unlocking gear, and the rotating shaft is kinetically connected to the unlocking gear and has one end inserted into the limiting hole. An unlocking button is provided at the free end of the unlocking rack. When the unlocking button is operated, the unlocking rack moves linearly and drives the unlocking gear to rotate, thereby disengaging the rotating shaft from the limiting hole, allowing the armrest to be opened from the unlocking button side. The two unlocking components include a first unlocking component and a second unlocking component. When the first unlocking component is in an unlocked state, the rotating shaft of the first unlocking component can restrict the linear movement of the unlocking rack of the second unlocking component toward the first unlocking component.

[0006] Optionally, when the second unlocking component is in the unlocked state, the pivot of the second unlocking component restricts the linear movement of the unlocking rack of the first unlocking component toward the first unlocking component.

[0007] Optionally, in each of the unlocking components, the pivot is disposed on the unlocking rack, and the unlocking rack is provided with a limiting protrusion; when the first unlocking component is in the unlocked state, the pivot of the first unlocking component is located on the moving path of the limiting protrusion of the second unlocking component; when the second unlocking component is in the unlocked state, the pivot of the second unlocking component is located on the moving path of the limiting protrusion of the first unlocking component.

[0008] Optionally, when the first unlocking component is in the unlocked state, the distance between the pivot of the first unlocking component and the limiting protrusion of the second unlocking component is greater than 1.

[0009] Optionally, when the second unlocking component is in the unlocked state, the distance between the pivot of the second unlocking component and the limiting protrusion of the first unlocking component is greater than 1.

[0010] Optionally, each of the rotating shafts includes a limiting portion, wherein the limiting portion of the first unlocking component abuts against the limiting protrusion of the second unlocking component, and the limiting portion of the second unlocking component abuts against the limiting protrusion of the first unlocking component; when both the first unlocking component and the second unlocking component are in the unlocked state, the limiting portion of the first unlocking component, the limiting protrusion of the second unlocking component, the limiting portion of the second unlocking component, and the limiting protrusion of the first unlocking component are sequentially arranged along a first direction, wherein the first direction is perpendicular to the moving direction of the unlocking rack.

[0011] Optionally, when the first unlocking component or the second unlocking component is in the unlocked state, the two unlocking racks abut against each other.

[0012] Optionally, each of the unlocking components further includes a first reset member, one end of which is connected to the handrail and the other end of which is connected to the pivot member.

[0013] Optionally, each of the unlocking components further includes a trigger, which includes a trigger part and a pivot part. The pivot part is rotatably connected to the armrest, and the trigger part is connected to the pivot part. One end of the trigger part abuts against the base so that the other end of the trigger part is limited to the pivot part.

[0014] Optionally, each of the unlocking components further includes a second reset member, one end of which is connected to the handrail and the other end of which is connected to the unlocking rack.

[0015] According to a second aspect of this application, a vehicle is provided that includes the armrest box described in the first aspect.

[0016] In the armrest box provided in this application embodiment, when the first unlocking component is in the unlocked state, since the moving direction of the pivot of the first unlocking component is different from the moving direction of the unlocking rack of the second unlocking component, the force exerted on the unlocking rack of the second unlocking component by pressing the unlocking button of the second unlocking component cannot drive the pivot of the first unlocking component to move back and forth. This can effectively limit the second unlocking component and avoid the problem that the first unlocking component and the second unlocking component will unlock simultaneously by pressing the unlocking button of the second unlocking component. Thus, it can effectively ensure that when the first unlocking component is in the unlocked state, the armrest box can only be opened from the side of the first unlocking component.

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0032] Some embodiments of this application provide an armrest box, such as Figures 1 to 3 As shown, the armrest box 100 includes a base 10, an armrest 40 disposed on the base 10, and a gear unlocking mechanism.

[0033] In some examples, such as Figure 1 As shown, the armrest 40 may include an outer armrest panel 41 and an inner armrest panel 42, which are connected together. The inner armrest panel 42 is used to install a gear unlocking mechanism. The outer armrest panel 41 can cover the gear unlocking mechanism, thus protecting the components (such as the gear unlocking mechanism) on the inner armrest panel 42 and ensuring the aesthetics of the armrest box 100.

[0034] As an example, the inner armrest panel 42 may include a first mounting plate 421 and a second mounting plate 422. The second mounting plate 422 is located on the side of the first mounting plate 421 near the base 10, and the first mounting plate 421 and the second mounting plate 422 are connected. The first mounting plate 421 can be used to install a gear unlocking mechanism, and the second mounting plate 422 can be used to install insulation components (such as ice packs or hot water bottles). By using the second mounting plate 422 to install insulation components, the storage space on the base 10 can have a certain degree of insulation performance, which is beneficial for storing items with high insulation requirements.

[0035] In some embodiments, the gear unlocking mechanism is connected to the base 10 and the armrest 40 (e.g., the first mounting plate 421). When the gear unlocking mechanism is locked, the user cannot drive the armrest 40 to move, and the armrest box 100 is in a closed state. When the gear unlocking mechanism is unlocked, the user can drive the armrest 40 to move, thereby opening the armrest box 100.

[0036] In this embodiment, as Figure 2 and Figure 3 As shown, the gear unlocking mechanism includes two unlocking components arranged opposite each other. Each unlocking component includes an unlocking rack 21, an unlocking gear 22, and a rotating shaft 23. The unlocking rack 21 meshes with the unlocking gear 22, and the rotating shaft 23 is drivenly connected to the unlocking gear 22. One end of the rotating shaft 23 is selectively inserted into a limiting hole on the base 10. Specifically, the base has two limiting holes, and the rotating shafts 23 of the two unlocking components are respectively inserted into their corresponding limiting holes.

[0037] Since the unlocking rack 21 meshes with the unlocking gear 22, the unlocking rack 21 can drive the unlocking gear 22 to rotate during movement. The rotation of the unlocking gear 22 further drives the rotating shaft 23 to move. When one end of the rotating shaft 23 is inserted into the limiting hole on the base 10, the gear unlocking mechanism is connected to the base 10. Since the gear unlocking mechanism is connected to the armrest 40, the armrest 40 is prevented from moving relative to the base 10, so that the armrest box 100 is in the closed state.

[0038] The free end of the unlocking rack 21 is equipped with an unlocking button 27. When the unlocking button 27 is activated, the unlocking rack 21 moves linearly and drives the unlocking gear 22 to rotate, thereby causing the rotating shaft 23 to disengage from the limiting hole, allowing the handrail 40 to be opened from the side of the unlocking button 27. The free end of the unlocking rack 21 refers to the end of the unlocking rack 21 that is opposite to its opposite unlocking component. That is, the ends of the unlocking racks 21 of the two unlocking components that are opposite to each other are considered the free ends.

[0039] As an example, the two unlocking components include a first unlocking component and a second unlocking component, for example, located in Figure 2 The unlocking component on the right is the first unlocking component, located in... Figure 2The unlocking component on the left is the second unlocking component. When the user operates (e.g., presses) the unlocking button 27 of the first unlocking component, the unlocking rack 21 of the first unlocking component moves linearly to the left and drives the unlocking gear 22 to rotate counterclockwise, thereby causing the rotating shaft 23 to move backward, thus disengaging the rotating shaft 23 from the limiting hole. Since the second unlocking component is in the locked state, the rotating shaft 23 of the second unlocking component is inserted into the corresponding limiting hole. At this time, the armrest 40 can be opened from the right side and rotated around the rotating shaft 23 of the second unlocking component. When the user presses the unlocking button 27 of the second unlocking component, the armrest 40 can be opened from the left side and rotated around the rotating shaft 23 of the first unlocking component.

[0040] In this embodiment, when the first unlocking component is in the unlocked state, the pivot 23 of the first unlocking component can restrict the unlocking rack 21 of the second unlocking component from moving linearly toward the first unlocking component.

[0041] With this configuration, since the pivot 23 moves in a forward-backward direction and the unlocking rack 21 moves in a left-right direction, meaning their directions are perpendicular, when the first unlocking component is in the unlocked state, the force exerted on the unlocking rack 21 by pressing the unlock button 27 of the second unlocking component, due to the different directions of movement between the pivot 23 and the unlocking rack 21, cannot drive the pivot 23 of the first unlocking component to move forward or backward. This effectively limits the second unlocking component, preventing the simultaneous unlocking of both components by pressing the unlock button 27. Therefore, when the first unlocking component is in the unlocked state, the armrest box 100 can only be opened from the side of the first unlocking component.

[0042] In some embodiments, please continue reading Figure 2 and Figure 3 When the second unlocking component is in the unlocked state, the pivot 23 of the second unlocking component restricts the unlocking rack 21 of the first unlocking component from moving linearly toward the first unlocking component.

[0043] With this configuration, when the second unlocking component is in the unlocked state, since the moving direction of the pivot 23 of the second unlocking component is different from the moving direction of the unlocking rack 21 of the first unlocking component, the force exerted on the unlocking rack 21 of the first unlocking component by pressing the unlocking button 27 of the first unlocking component cannot drive the pivot 23 of the second unlocking component to move back and forth. This can effectively limit the first unlocking component and avoid the problem of the first and second unlocking components being unlocked simultaneously by pressing the unlocking button 27 of the first unlocking component. Thus, it can effectively ensure that when the second unlocking component is in the unlocked state, the armrest box 100 can only be opened from the side of the second unlocking component.

[0044] In some examples, the armrest 40 (e.g., the inner armrest panel 42) is provided with at least one set of limiting elements to restrict the movement of the unlocking rack 21 along its extension direction (left-right direction).

[0045] In some embodiments, please continue reading Figure 2 and Figure 3 In each unlocking component, a pivot 23 is mounted on the unlocking rack 21. The pivot 23 does not interfere with the unlocking rack 21 during forward and backward movement; similarly, the unlocking rack 21 does not interfere with the pivot 23 during left and right movement. In other words, the pivot 23 and the unlocking rack 21 do not obstruct each other's movement.

[0046] The unlocking rack 21 is provided with a limiting protrusion 211. When the first unlocking component is in the unlocked state, the pivot 23 of the first unlocking component is located on the movement path of the limiting protrusion 211 of the second unlocking component. When the second unlocking component is in the unlocked state, the pivot 23 of the second unlocking component is located on the movement path of the limiting protrusion 211 of the first unlocking component.

[0047] By setting a limiting protrusion 211 on the unlocking rack 21, the movement of the unlocking rack 21 can be restricted by positioning the pivot 23 on the movement path of the limiting protrusion 211. This effectively ensures that the armrest box 100 can only be opened from one side.

[0048] This means that, since the pivot 23 is mounted on the unlocking rack 21, the limiting protrusion 211 on the unlocking rack 21 needs to be on the same horizontal plane as the pivot 23 of the other unlocking component, so as to ensure that the pivot 23 of the other unlocking component blocks the movement of the unlocking rack 21.

[0049] In some examples, please refer to [link / reference]. Figure 2 and Figure 3When the first unlocking component is in the unlocked state, the distance between the pivot 23 of the first unlocking component and the limiting protrusion 211 of the second unlocking component is greater than 0. That is, when the first unlocking component is in the unlocked state, the unlocking button 27 of the second unlocking component needs to be pressed and the unlocking rack 21 of the second unlocking component needs to be moved a certain distance before the limiting protrusion 211 of the second unlocking component will abut against the pivot 23 of the first unlocking component.

[0050] This design avoids the contact between the pivot 23 of the first unlocking component and the limiting protrusion 211 of the second unlocking component each time the first unlocking component is driven into the unlocked state, thus preventing the force between them from acting on each other and effectively preventing the pivot 23 of the first unlocking component and the limiting protrusion 211 of the second unlocking component from colliding and being damaged.

[0051] As an example, when the first unlocking component is in the unlocked state, the distance between the pivot 23 of the first unlocking component and the limiting protrusion 211 of the second unlocking component is greater than or equal to 1 mm and less than or equal to 2 mm. For example, the distance can be 1 mm, 1.5 mm, or 2 mm, etc.

[0052] In some examples, when the second unlocking component is in the unlocked state, the distance between the pivot 23 of the second unlocking component and the limiting protrusion 211 of the first unlocking component is greater than 0. That is, when the second unlocking component is in the unlocked state, the unlocking button 27 of the first unlocking component needs to be pressed and the unlocking rack 21 of the first unlocking component needs to be moved a certain distance for the limiting protrusion 211 of the first unlocking component to abut against the pivot 23 of the second unlocking component.

[0053] This design avoids the situation where the pivot 23 of the second unlocking component comes into contact with the limiting protrusion 211 of the first unlocking component every time the second unlocking component is driven into the unlocked state, thus preventing the two components from exerting force on each other. This effectively prevents the pivot 23 of the second unlocking component from colliding with the limiting protrusion 211 of the first unlocking component and being damaged.

[0054] As an example, when the second unlocking component is in the unlocked state, the distance between the pivot 23 of the second unlocking component and the limiting protrusion 211 of the first unlocking component is greater than or equal to 1 mm and less than or equal to 2 mm. For example, the distance can be 1 mm, 1.5 mm, or 2 mm, etc.

[0055] In some embodiments, please continue reading Figure 2 Each pivot component 23 includes a limiting part 231, the limiting part 231 of the first unlocking component is used to abut against the limiting protrusion 211 of the second unlocking component, and the limiting part 231 of the second unlocking component is used to abut against the limiting protrusion 211 of the first unlocking component.

[0056] When both the first unlocking component and the second unlocking component are in the unlocked state, along the first direction, the limiting part 231 of the first unlocking component, the limiting protrusion 211 of the second unlocking component, the limiting part 231 of the second unlocking component, and the limiting protrusion 211 of the first unlocking component are sequentially arranged, and the first direction is perpendicular to the moving direction of the unlocking rack 21. Figure 2 As shown, the limiting part 231 of the first unlocking component, the limiting protrusion 211 of the second unlocking component, the limiting part 231 of the second unlocking component, and the limiting protrusion 211 of the first unlocking component are arranged sequentially in the rearward direction.

[0057] For the first unlocking component, during the unlocking process, the limiting part 231 moves backward a certain distance. When the first unlocking component is in the unlocked state, the limiting part 231 of the first unlocking component aligns with the limiting protrusion 211 of the second unlocking component. This causes the pivot 23 of the first unlocking component to restrict the movement of the unlocking rack 21 of the second unlocking component, thereby ensuring that the armrest 40 can only be opened from the side (right side) where the first unlocking component is located. Similarly, for the second unlocking component, during the unlocking process, the limiting part 231 moves backward a certain distance. When the second unlocking component is in the unlocked state, the limiting part 231 of the second unlocking component aligns with the limiting protrusion 211 of the first unlocking component. This causes the pivot 23 of the second unlocking component to restrict the movement of the unlocking rack 21 of the first unlocking component, thereby ensuring that the armrest 40 can only be opened from the side (left side) where the second unlocking component is located. Therefore, by sequentially arranging the limiting part 231 of the first unlocking component, the limiting protrusion 211 of the second unlocking component, the limiting part 231 of the second unlocking component, and the limiting protrusion 211 of the first unlocking component in a rearward direction, the above process can be successfully achieved.

[0058] In some embodiments, please continue reading Figure 2 When the first or second unlocking component is in the unlocked state, the two unlocking racks 21 abut against each other. That is, the unlocking racks 21 of the two unlocking components are set opposite each other. During the unlocking process of one unlocking component, the unlocking rack 21 of that unlocking component moves toward the unlocking rack 21 of the other unlocking component until the two unlocking racks 21 abut against each other, at which point the unlocking component is in the unlocked state.

[0059] This configuration allows for the limiting of the two unlocking racks 21 by their abutting action, thus further ensuring that when one unlocking component is in the unlocked state, the other unlocking component is difficult to unlock, thereby ensuring that the armrest 40 can be opened on one side.

[0060] In some embodiments, please continue reading Figure 2 and Figure 3Each unlocking component also includes a first reset member 31, which extends in the front-to-back direction. One end of the first reset member 31 is connected to the armrest 40 (e.g., the inner panel 42 of the armrest), and the other end is connected to the pivot member 23.

[0061] By setting the first reset member 31, a restoring force is provided to the rotating shaft 23 when the unlocking component is in the unlocked state, which facilitates the reset of the unlocking component and makes the unlocking component usable in the future.

[0062] As an example, the inner panel 42 of the handrail is provided with a first mounting part, which is connected to one end of a first reset member 31. The other end of the first reset member 31 is connected to a second mounting part of a pivot member 23. The first reset member 31 extends in the front-back direction. When the handrail 40 is closed, the first reset member 31 is in its initial state, and the pivot member 23 is not under tension. During the opening of the handrail 40 from the left or right side, the pivot member 23 on the corresponding side moves backward, the first reset member 31 is stretched, and the first reset member 31 exerts a tension on the pivot member 23.

[0063] In some embodiments, such as Figures 2 to 4 As shown, each unlocking component also includes a trigger 25, which comprises a trigger portion 251 and a pivot portion 252. The pivot portion 252 is rotatably connected to the inner armrest plate 42, and the trigger portion 251 is connected to the pivot portion 252. One end of the trigger portion 251 abuts against the base 10, so that the other end of the trigger portion 251 is in a limiting engagement with the pivot member 23. Specifically, the pivot portion 252 is rotatably connected to the inner armrest plate 42, and the pivot portion 252 allows the trigger 25 to rotate, thereby cooperating with the pivot member 23 to ensure that the armrest 40 can only be opened from one side.

[0064] The trigger part 251 has a limiting step 253 at the other end, which engages with the rotating shaft 23. The base 10 has an opening, and when the armrest 40 is closed, one end of the trigger part 251 abuts against the opening, and the limiting step 253 engages with the rotating shaft 23 at this time.

[0065] During the process of switching the handrail 40 from the open state to the closed state, one end of the trigger part 251 can abut against the opening, and under the action of the opening, the trigger part 251 gradually flips inward so that the limiting step 253 and the rotating shaft 23 are released from the limit. Then, the rotating shaft 23 moves forward under the pulling force of the first reset member 31 until the rotating shaft 23 is limited and engaged with the limiting hole on the base 10, ensuring that the handrail 40 is in the closed state.

[0066] During the process of switching the handrail 40 from the closed state to the open state, one end of the trigger 251 gradually separates from the opening, the trigger 251 gradually flips outward, and the pivot 23 moves backward. When the handrail 40 is in the open state, the other end of the trigger 25 abuts against the pivot 23, so that the limiting step 253 and the pivot 23 are limited, preventing the pivot 23 from moving forward under the action of the first reset member 31, and ensuring that the handrail remains in the open state.

[0067] In some examples, each unlocking component also includes a trigger spring 26, which is sleeved on the pivot portion 252. One end of the trigger spring 26 abuts against the inner armrest plate 42 and the other end abuts against the trigger portion 251. Specifically, the trigger spring 26 is sleeved on the outer periphery of the pivot portion 252 and abuts against the trigger portion 251 and the inner armrest plate 42.

[0068] The trigger spring 26 can cause the trigger 25 to flip outward so that one end of the trigger part 251 is limited to the rotating shaft 23, preventing the rotating shaft 23 from resetting under the action of tension.

[0069] In some embodiments, please continue reading Figures 2 to 4 Each unlocking component also includes a second reset member 32, one end of which is connected to the inner plate 42 of the armrest, and the other end is connected to the unlocking rack 21.

[0070] For any unlocking component, when its unlocking button 27 is pressed, the unlocking rack 21 moves to the other side in the left-right direction. When the unlocking component is in the unlocked state, the armrest 40 can be opened from that side, and the second reset member 32 is compressed. At this time, the unlocking rack 21 is pushed by the second reset member 32. Due to the limiting engagement between the pivot member 23 and the trigger 25, the unlocking rack 21 maintains its current state. During the closing of the armrest 40, the pivot member 23 and the trigger 25 are released from their limiting positions, and the unlocking rack 21 can be reset under the pushing force of the second reset member 32, thereby resetting the corresponding unlocking button 27.

[0071] In some embodiments, please continue reading Figure 2 and Figure 3For each unlocking component, the rotating shaft 23 is provided with a first limiting protrusion, and the unlocking gear 22 has a first limiting hole 221 on one side. The first limiting protrusion and the first limiting hole 221 are in a limiting engagement. Specifically, the first limiting protrusion is perpendicular to the rotating shaft 23, and the first limiting hole 221 is provided on one side of the outer periphery of the unlocking gear 22. The first limiting protrusion and the first limiting hole 221 are in a limiting engagement. The first limiting protrusion passes through the first limiting hole 221 in the height direction. The diameter of the first limiting hole 221 is larger than that of the first limiting protrusion, so that the first limiting protrusion can move within the first limiting hole 221. Since the first limiting hole 221 also has displacement in the left and right directions when the unlocking gear 22 rotates, the diameter of the first limiting hole 221 is set to be larger than that of the first limiting protrusion, so that the rotating shaft 23 can move in the front and back directions, and the rotating shaft 23 is in a limiting engagement with the trigger 25.

[0072] In some embodiments, please continue reading Figure 2 and Figure 4 Each unlocking component also includes a pivot 24 and a linkage assembly. The pivot 24 is connected to the unlocking gear 22. The linkage assembly is located on the side of the pivot 24 opposite to the unlocking gear 22. The pivot 24 is connected to the linkage assembly to release the pivot 24 from locking the handrail 40.

[0073] The unlocking gear 22 is connected to the rotating shaft 23 and the rotating shaft body 24, and the unlocking rack 21 meshes with the unlocking gear 22. When the unlocking button 27 of any unlocking component is pressed, the unlocking rack 21 moves and drives the unlocking gear 22 to rotate. At this time, the rotating shaft 23 moves backward and the rotating shaft body 24 moves forward until the rotating shaft 23 and the rotating shaft body 24 release the restriction on the handrail 40, and the handrail 40 can be opened from the side where the unlocking component is located.

[0074] In some examples, please refer to Figure 2 and Figure 3 One end of the rotating shaft 24 is provided with a second limiting protrusion, and the unlocking gear 22 is provided with a second limiting hole 222. The second limiting protrusion and the second limiting hole 222 are engaged in a limiting fit. As an example, the other side of the outer periphery of the unlocking gear 22 is provided with a second limiting hole 222. The second limiting hole 222 and the first limiting hole 221 are disposed opposite to each other on both sides of the unlocking gear 22, and the second limiting protrusion and the second limiting hole 222 are engaged in a limiting fit. Specifically, the second limiting protrusion passes through the second limiting hole 222 in the height direction. The diameter of the second limiting hole 222 is larger than that of the second limiting protrusion, so that the second limiting protrusion can move within the second limiting hole 222. Since the second limiting hole 222 also has displacement in the left and right directions when the unlocking gear 22 rotates, the diameter of the second limiting hole 222 is set to be larger than that of the second limiting protrusion, so that the rotating shaft 24 can move in the front and back directions.

[0075] In some embodiments, please refer to Figure 2 and Figure 4 The armrest box 100 also includes a fixing seat 39, which is fixedly connected to the base 10. The linkage assembly includes a linkage 34, which is arranged adjacent to the fixing seat 39. The other end of one of the rotating shafts 24 (i.e., the end of the rotating shaft 24 away from the unlocking gear 22) passes through one end of the linkage 34 and is limited to the fixing seat 39. The other end of the other rotating shaft 24 is limited to the other end of the linkage 34.

[0076] The linkage assembly also includes a first linkage shaft 35 and a second linkage shaft 36. The first linkage shaft 35 is sleeved on the outer periphery of a rotating shaft body 24. The second linkage shaft 36 connects the inner plate of the handrail 42 and one end of the connecting rod 34, and connects the fixed seat 39 and the other end of the connecting rod 34. The second linkage shaft 36 is in a limiting engagement with the other end of the other rotating shaft body 24, so that the handrail and the other end of the connecting rod 34 are selectively rotatably connected. Specifically, the first linkage shaft 35 passes through one end of the connecting rod 34 from one side and is in a limiting engagement with the fixed seat 39; the second linkage shaft 36 is mounted on the fixed seat 39, and passes through the other end of the connecting rod 34 from the other side and is in a limiting engagement with the rotating shaft body 24.

[0077] In some examples, the linkage assembly also includes a first linkage spring 37 and a second linkage spring 38, which are respectively disposed between the first linkage shaft 35 and the link 34, and between the second linkage shaft 36 and the link 34. The first linkage spring 37 is disposed between one end of the first linkage shaft 35 and the link 34, and the second linkage spring 38 is disposed between the second linkage shaft 36 and the other end of the link 34.

[0078] As an example, the first connecting rod shaft 35 is located on the right side of the handrail 40, and the second connecting rod shaft 36 is located on the left side of the handrail 40. For the right-side pivot member 23, the portion inserted into the limiting hole is coaxial with the first connecting rod shaft 35; for the left-side pivot member 23, the portion inserted into the limiting hole is coaxial with the second connecting rod shaft 36. This arrangement facilitates the rotation of the handrail 40 around the pivots on the corresponding sides.

[0079] In some examples, the armrest box 100 also includes a damping drive shaft 51, with a first link spring 37 that can cooperate with the damping drive shaft 51 to dissipate vibrational energy during the rotation of the armrest 40 and optimize the dynamic performance of the armrest 40 during rotation.

[0080] In some examples, the armrest box 100 also includes an armrest mounting plate 52 having an opening through which the pivot body 24 is disposed.

[0081] In some embodiments, please continue reading Figures 2 to 4Each unlocking component also includes a third reset member 33, which extends in the left-right direction. One end of the third reset member 33 is connected to the inner armrest plate 42, and the other end is connected to the pivot 24. Specifically, the third reset member 33 is connected between the inner armrest plate 42 and the pivot 24, and the third reset member 33 can ensure that the pivot 24 moves in the front-back direction to avoid the pivot 24 deviating from the trajectory and getting stuck.

[0082] The armrest box 100 described in the above embodiment operates as follows:

[0083] When the armrest 40 is opened from the left, the unlock button 27 on the left can be pressed. Under the rotation of the unlock gear 22 on the left, the left pivot 23 moves backward and disengages from the limiting hole on the left side of the base 10. At this time, the right pivot 23 is still in the limiting hole on the right side of the base 10. In addition, the left pivot 24 moves forward, disengaging from the left end of the connecting rod 34. Then, the second connecting rod shaft 36 connects the fixed seat 39 and the left end of the connecting rod 34. At this time, the right pivot 24 passes through the right end of the connecting rod 34 and engages with the fixed seat 39. The first connecting rod shaft 35 and the first connecting rod spring 37 cause the inner plate of the armrest 42 to rotate and connect with the fixed seat 39. Under the action of the first connecting rod spring 37, the inner plate of the armrest 42 rotates around the part of the first connecting rod shaft 35 and the right pivot 23 located in the limiting hole, that is, the armrest 40 flips to the right. Meanwhile, the pivot 24 connects the inner plate 42 of the handrail and the fixed seat 39, ensuring the connection between the handrail 40 and the base 10 and preventing the handrail 40 from falling off the base 10. Under the action of the first link spring 37, the handrail 40 can be tilted to the right relative to the base 10, so that the handrail 40 can be opened from the left.

[0084] When the armrest 40 is opened from the right, the unlock button 27 on the right can be pressed. With the rotation of the unlock gear 22 on the right, the right pivot 23 moves backward, disengaging from the limiting hole on the right side of the base 10. At this time, the left pivot 23 remains within the limiting hole on the left side of the base 10. Furthermore, the right pivot 24 moves forward, disengaging from the right end of the connecting rod 34. The first connecting rod shaft 35 and the first connecting rod spring 37 connect to the right end of the connecting rod 34. At this time, the right pivot 24 disengages from the fixed seat 39, and the first connecting rod shaft 35 and the second connecting rod spring 38 are sleeved on the outer circumference of the left pivot 24. The left pivot 24 and the second connecting rod spring 38 then engage in a limiting fit, allowing the armrest to rotate and connect with the fixed seat 39, preventing the armrest from detaching from the base 10. Under the action of the second link spring 38, the link 34 and the handrail 40 rotate around the left pivot 23, that is, the handrail 40 can be tilted to the left relative to the base 10, so that the handrail 40 can be opened from the right.
