Description

Technical Field

[0001] The invention belongs to the technical field of automobile accessories, and in particular relates to an automobile armrest assembly. Background Art

[0002] The car armrest is a car accessory installed between two seats and belongs to the car interior system. Taking the rear armrest of the car as an example, the rear armrest is set in the rear of the car in a flip-open manner, which can improve the riding experience of the rear passengers and ultimately achieve the purpose of improving market competitiveness.

[0003] The rear armrests in the prior art have integrated many structures or functions. For example, cup holders, cup holders, etc. are arranged in the rear armrests, or storage compartments are arranged in the rear armrests, but the cup holders, storage compartments, etc. are fixedly arranged on the rear armrests. When the rear passengers have bags of goods or garbage bags, there is a lack of hook components that can be used. When using mobile phones or tablets, there is also a problem that the mobile phones or tablets cannot be placed on the stands. Therefore, the flip-open rear armrests in the prior art have the problem that they cannot provide hooks and cannot serve as stands. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that the flip-open rear armrest in the prior art cannot provide a hook and cannot serve as a bracket.

[0005] In order to solve the above technical problems, an embodiment of the present invention discloses an automobile armrest assembly, including an armrest body and an armrest extension mechanism that can be extended on the armrest body, one end of the armrest body is rotatably connected to the vehicle body, and the armrest extension mechanism can extend the armrest body from the other end of the armrest body. The armrest extension mechanism includes an end cover, a linkage assembly and a locking assembly. One end of the linkage assembly is rotatably connected to the armrest body, and the other end is rotatably connected to the end cover, and the linkage assembly switches between a folded state and an open state relative to the armrest body. The locking assembly is arranged between the armrest body and the linkage assembly, and can lock the linkage assembly in a folded state or an open state respectively.

[0006] When the linkage assembly is in a folded state relative to the armrest body and locked by the locking assembly, the end cover abuts against a corresponding area of ​​the end of the armrest body. And when the linkage assembly is in an open state relative to the armrest body, the linkage assembly at least partially extends out of the armrest body and drives the end cover to leave the end of the armrest body.

[0007] With the above technical solution, when the armrest body is flipped open relative to the vehicle body, the armrest extension mechanism can extend the armrest body from the end of the armrest body away from the vehicle body. After the armrest extension mechanism is extended and opened, it has a multifunctional auxiliary function. For example, you can hang a bag of goods or a garbage bag on the end cover, or you can use the opened end cover and the armrest body as a stand to place a mobile phone or tablet for use. The extended end cover can be used for multiple purposes, which solves the problem of inconvenient placement of bags, mobile phones, etc. for rear passengers. And when not in use, the armrest extension mechanism is equivalent to a part of the armrest body, which can be easily folded on the vehicle body or the rear seat, just like a common flip armrest.

[0061] In order to make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0062] Example 1

[0063] The implementation method of this embodiment discloses a vehicle armrest assembly, see Figure 1 and Figure 2 , comprising an armrest body 100 and an armrest extension mechanism 200 which is extendably arranged on the armrest body 100, one end of the armrest body 100 is rotatably connected to the vehicle body (not shown in the figure), and the armrest extension mechanism 200 can extend out of the armrest body 100 from the other end of the armrest body 100. The armrest extension mechanism 200 comprises an end cover 210, a linkage assembly 220 and a locking assembly 230. One end of the linkage assembly 220 is rotatably connected to the armrest body 100, and the other end is rotatably connected to the end cover 210, and the linkage assembly 220 is switched between a folded state and an open state relative to the armrest body 100. The locking assembly 230 is arranged between the armrest body 100 and the linkage assembly 220, and can lock the linkage assembly 220 in a folded state or an open state respectively.

[0064] When the linkage assembly 220 is in a folded state relative to the armrest body 100 and locked by the locking assembly 230, the end cover 210 abuts against the corresponding area of ​​the end of the armrest body 100. And when the linkage assembly 220 is in an open state relative to the armrest body 100, the linkage assembly 220 at least partially extends out of the armrest body 100 and drives the end cover 210 to leave the end of the armrest body 100.

[0065] Specifically, in the present embodiment, the automobile armrest assembly is arranged on the backrest of the rear seat of the automobile as an example for explanation. The automobile armrest assembly is located in the middle of the backrest and is rotatably connected to the backrest by a rotating shaft or a pin shaft. When the armrest needs to be opened, the armrest assembly can be rotated to open. When the armrest extension mechanism 200 needs to be used after opening, the linkage assembly 220 is unlocked by the locking assembly 230 relative to the armrest body 100 and opened for use. At this time, the end cover 210 extends forward from the side of the armrest body 100 away from the backrest. At the end of use, the linkage assembly 220 is continued to be locked by the locking assembly 230 and the end cover 210 is made to abut against the corresponding area covering the end of the armrest body 100. When the armrest is not in use, the automobile armrest assembly is flipped over so that the automobile armrest assembly becomes a part of the backrest.

[0066] More specifically, the linkage assembly 220, the armrest body 100 and the end cover 210 can be rotatably connected via a rotating shaft, a pivot, a pin, etc., and when the linkage assembly 220 is in a folded state, it abuts against one end of the armrest body 100. When the linkage assembly 220 is in an opened state, the linkage assembly 220 extends toward a side away from the armrest body 100.

[0067] Furthermore, when the armrest body 100 is flipped open relative to the vehicle body, the armrest extension mechanism 200 can extend out of the armrest body 100 from the end of the armrest body 100 away from the vehicle body. After the armrest extension mechanism 200 is extended and opened, it has a multifunctional auxiliary function. For example, a bag of goods or a garbage bag can be hung on the end cover 210, or the opened end cover 210 and the armrest body 100 can be used as a stand to place a mobile phone or tablet for use. The extended end cover 210 can be used for multiple purposes, solving the problem of inconvenient placement of bags of goods, mobile phones, etc. for rear passengers. Furthermore, when not in use, the armrest extension mechanism 200 is equivalent to a part of the armrest body 100, and can be easily folded on the vehicle body or the rear seat, which is the same as a common flip armrest.

[0068] Furthermore, the armrest extension mechanism 200 disclosed in the present application includes an end cover 210, a linkage assembly 220 and a locking assembly 230. The locking assembly 230 can control the linkage assembly 220 to switch between a folded state or an open state relative to the armrest body 100, and has the advantages of simple structure and convenient and quick control and opening.

[0069] The implementation of this embodiment also discloses an automobile armrest assembly, wherein the linkage assembly 220 includes a connecting rod component that can be folded relative to the armrest body 100. When the connecting rod component is in a folded state relative to the armrest body 100, the connecting rod component is compressed and has an elastic compression force; when the locking assembly 230 releases the lock on the connecting rod component, the elastic compression force pushes the connecting rod component to unfold and drives the end cover 210 to leave the end of the armrest body 100. The connecting rod component is any one of a rotating shaft connecting rod, an elastic connecting rod, and a scissor-type connecting rod.

[0070] Specifically, taking the connecting rod component as a rotating shaft connecting rod as an example, the rotating shaft connecting rod is provided with at least two sections and the middle part of the rotating shaft connecting rod is provided as the rotating shaft 224, so the rotating shaft connecting rod can be relatively folded or opened; the elastic connecting rod is similar to the rotating shaft connecting rod and can be switched between the folded and opened states, and also has elastic force in the folded state, the scissor-type connecting rod can also be relatively folded or opened, and when a spring, a coil spring or other components are provided on the middle rotating shaft of the scissor-type connecting rod, it has elastic compression force in the folded state, so it can automatically open and move away from the end of the armrest body 100 after being unlocked. By providing such a foldable connecting rod component with elastic compression force, it is convenient to control the folding or opening of the end cover 210, and after the connecting rod component folds to drive the end cover 210 to fold and is locked by the locking assembly 230, the connecting rod component has elastic compression force, and after the locking assembly 230 is unlocked, the connecting rod component drives the end cover 210 to open relative to the armrest body 100.

[0071] Next, the specific structure of the locking assembly 230 is described. The locking assembly 230 includes an elastic lock buckle provided on the armrest body 100. The elastic lock buckle includes a lock tongue extending from the armrest body 100 toward the connecting rod component and being able to move relative to the armrest body 100 to lock / unlock the connecting rod component. The elastic lock buckle can be repeatedly used and can automatically reset after being pressed, thereby locking the connecting rod component through the lock tongue.

[0072] See also Figure 1 and Figure 2 The link component includes a pair of elastic links 221, and the pair of elastic links 221 are respectively arranged on both sides of the armrest body 100 in the width direction.

[0073] One end of each elastic link 221 is rotatably connected to one side edge of the armrest body 100, and the other end is rotatably connected to the corresponding side end of the end cover 210, and each elastic link 221 can be switched between a folded state and an open state, and when at least one / or all of a pair of elastic links 221 are in an open state, the elastic link 221 drives the end cover 210 to leave the end of the armrest body 100; when both elastic links 221 are in a folded state and locked by the elastic lock, the end cover 210 abuts against the end of the armrest body 100 and is closed relative to the armrest body 100.

[0074] Specifically, when at least one or all of the pair of elastic connecting rods 221 mentioned in this embodiment are in the open state, the elastic connecting rod 221 drives the end cover 210 to leave the end of the armrest body 100: when both elastic connecting rods 221 are in the folded state and locked by the elastic lock buckle, Figure 3 As shown, the end cap 210 is now a part of the armrest body 100. Figure 8 As shown, when the two elastic connecting rods 221 are fully opened, the armrest extension mechanism 200 is in a fully opened state. Fig. 9 As shown, when the elastic link 221 on the left side is opened, the armrest extension mechanism 200 is half opened and the opened end cover 210 is closer to the left side, as shown in FIG. Fig.10 As shown, when the elastic link 221 on the right side is opened, the armrest extension mechanism 200 is half opened and the opened end cover 210 is closer to the right side.

[0075] With this structural design, an elastic connecting rod 221 is provided. When the two elastic connecting rods 221 are in a folded state and locked by the elastic lock, the end cover 210 is closed relative to the armrest body 100 and forms a part. The elastic connecting rod 221 also has an elastic compression force, which can drive the end cover 210 to open automatically after being unlocked.

[0076] For a further detailed description of the structure of the elastic connecting rod 221, see Figure 4Each elastic connecting rod 221 includes a first rod portion 222 , a second rod portion 223 , a rotating shaft 224 and an elastic reset member 225 .

[0077] The corresponding ends of the first rod portion 222 and the second rod portion 223 are rotatably connected through the rotating shaft 224, and the elastic reset member 225 is sleeved on the outer circumference of the rotating shaft 224, and the two ends of the elastic reset member 225 are respectively abutted against the first rod portion 222 and the second rod portion 223. The other end of one of the first rod portion 222 and the second rod portion 223 is rotatably connected to the armrest body 100, and the other end of the other is rotatably connected to the end cover 210. And when the first rod portion 222 and the second rod portion 223 are in a folded state, the elastic reset member 225 is in a compressed state. The elastic reset member 225 can be a common reset spring, a compression spring, a coil spring, etc.

[0078] For details, see Figure 4 and Figure 5 In this embodiment, the ends of the first rod portion 222 and the second rod portion 223 that are rotatably connected are provided with two rotating shafts 224, and the rotating shaft 224 also has a cavity for sleeve-mounting an elastic reset member 225, and the elastic reset member 225 is sleeved in the cavity. It is understandable that those skilled in the art can also sleeve the elastic reset member 225 on the outer periphery of the rotating shaft 224 or adopt other rotatable connection methods in other ways, and this embodiment does not specifically limit this. Through the design of this structure, the elastic reset member 225 is sleeved on the rotating shaft 224, and when the first rod portion 222 and the second rod portion 223 are folded, the elastic reset member 225 is compressed to provide elastic force, and at this time the elastic connecting rod 221 also has elastic compression force.

[0079] For further description of the specific structure of the elastic reset member 225, see Figure 4 The elastic reset member 225 includes a torsion spring, which includes a spring body 226 sleeved on the outer periphery of the rotating shaft 224 and two clamping feet 227 extending from both ends of the spring body 226. The two clamping feet 227 are respectively in contact with the corresponding ends of the first rod portion 222 and the second rod portion 223. Figure 5 and Figure 6 As shown, when the elastic link 221 is in a folded state, the torsion spring is in a torsion compression state; Figure 4 As shown, when the elastic link 221 is in the open state, the torsion spring is in the reset state.

[0080] With this arrangement, the two clips 227 of the torsion spring are respectively connected to the corresponding ends of the first rod portion 222 and the second rod portion 223. When the first rod portion 222 and the second rod portion 223 are folded, the first rod portion 222 and the second rod portion 223 drive the two abutting clips 227 to deform, and drive the spring body 226 to deform as well. At this time, the spring body 226 also has elastic potential energy and transfers the elastic potential energy to the first rod portion 222 and the second rod portion 223. When the locking assembly 230 is locked, the first rod portion 222 and the second rod portion 223 are folded together. When the locking assembly 230 is unlocked, the first rod portion 222 and the second rod portion 223 are bounced apart by the torsion spring.

[0081] See also Figure 5 When each elastic link 221 is in the folded state, the first rod portion 222 and the second rod portion 223 are folded together to form a "two" shape, and the elastic reset member 225 is in a compressed state. Figure 6 When the two elastic links 221 are in a folded state, the rotating shafts 224 of the two elastic links 221 are arranged opposite to each other, that is, the two elastic links 221 are folded together with the rotating shafts 224 facing each other when in the folded state. Only in this way can the first rod portion 222 and the second rod portion 223 of the two elastic links 221 be close to each other and located at one end of the armrest body 100.

[0082] See also Figure 4 When each elastic link 221 is in the open state, the first rod portion 222 and the second rod portion 223 extend in the same direction and form a "one" shape as a whole, and the elastic reset member 225 is in the reset state. Fig. 9 and Fig.10 Each elastic link 221 can also be in a semi-open state. When the elastic link 221 is in the semi-open state, the first rod portion 222 and the second rod portion 223 are perpendicular to each other and form an "L" shape as a whole, and the elastic reset member 225 is in a partially compressed state. It is precisely because the elastic link 221 in this embodiment has multiple opening modes that the corresponding end cover 210 can also be opened and present different states.

[0083] See also Figure 4 and Figure 5, a plurality of spaced-apart weight-reducing cavities 228 are disposed on the first rod portion 222 and the second rod portion 223. A plurality of abutment portions 229 are disposed on the first rod portion 222 and the second rod portion 223 on the side close to each other when the elastic connecting rod 221 is in the folded state. The abutment portions 229 on the first rod portion 222 and the second rod portion 223 are spaced-apart and staggered, and the first rod portion 222 and the second rod portion 223 are kept parallel to each other when the elastic connecting rod 221 is in the folded state. With this design, a plurality of weight-reducing holes can be provided to reduce the weight of the first rod portion 222 and the second rod portion 223, and as Figure 4 and Figure 5 As shown, the first rod portion 222 and the second rod portion 223 may be respectively provided with two abutment portions 229, and those skilled in the art may set three, four or even more abutment portions 229 according to actual needs, and multiple abutment portions 229 are set to ensure that the first rod portion 222 and the second rod portion 223 extend parallel to each other in the folded state.

[0084] Next, the specific structure of the locking assembly 230 is described. Figure 2 and Figure 7 The locking assembly 230 includes a pair of elastic lock buckles corresponding to the pair of elastic connecting rods 221. Each elastic lock buckle includes a lock tongue extending from the armrest body 100 toward the elastic connecting rod 221, a compression spring 231 is arranged at the bottom of the lock tongue and in the armrest body 100, and a hook 232 is arranged at the end of the lock tongue close to the elastic connecting rod 221.

[0085] One of the first rod portion 222 and the second rod portion 223 of the elastic connecting rod 221 close to the armrest body 100 is provided with a slot adapted to the hook 232 . When the elastic connecting rod 221 is in the folded state, the hook 232 is adapted to be engaged with the slot.

[0086] With this structural design, an elastic lock is provided. When the first rod 222 and the second rod 223 are locked by the hook 232 and the slot, the compression spring 231 abuts against the lock tongue to provide elastic force to prevent the hook 232 and the slot from being separated by external force.

[0087] Please note that, see Figure 6 Although the hook 232 of the lock tongue is only connected to one of the first rod portion 222 and the second rod portion 223, when the two elastic links 221 are folded, the rotating shafts 224 are arranged opposite to each other, and the other ends of the two elastic links 221 are simultaneously connected to the end cover 210. Therefore, the end cover 210 will restrict the two elastic links 221, and the hook 232 of the lock tongue only restricts one of the rods to achieve the folding and fixing of the elastic links 221.

[0088] For further information, see Figure 7The locking assembly 230 also includes a switch assembly, which is disposed on the armrest body 100 and includes a first button, a middle button, and a second button that are sequentially disposed.

[0089] The first button includes a first button 233 exposed from the armrest body 100 , and a first pressing rod 234 disposed at the bottom of the first button 233 , and an end of the first pressing rod 234 abuts against a top of the first locking tongue 235 .

[0090] The second button includes a second button 236 exposed from the armrest body 100 , and a second pressing rod 237 disposed at the bottom of the second button 236 , and an end of the second pressing rod 237 abuts against a top of the second locking tongue 238 .

[0091] The middle button includes a middle button 239 and a synchronous pressing rod 240 arranged at the bottom of the middle button 239 and extending toward the first lock tongue 235 and the second lock tongue 238 respectively. The ends of the synchronous pressing rod 240 abut against the tops of the first lock tongue 235 and the second lock tongue 238 at the same time.

[0092] The pressing process of the switch assembly is briefly described: for example, when the first button 233 is pressed, the first button 233 drives the first pressing rod 234 at the bottom to move downward and drives the first locking tongue 235 to move downward. At this time, the hook 232 of the first locking tongue 235 is separated from the slot on the elastic connecting rod 221, and the compression spring 231 at the bottom is compressed. After the pressing is completed, the elastic connecting rod 221 corresponding to the first locking tongue 235 is separated from the locking tongue, and the locking tongue and the first button 233 are rebounded to the initial position by the compression spring 231. Similarly, when the second button 236 is pressed, the second button 236 drives the second pressing rod 237 at the bottom to move downward and drives the second locking tongue 238 to move downward. At this time, the hook 232 of the second locking tongue 238 is separated from the slot on the elastic connecting rod 221, and the compression spring 231 at the bottom is compressed. After the pressing is completed, the elastic connecting rod 221 corresponding to the second locking tongue 238 is separated from the locking tongue, and the locking tongue and the second button 236 are rebounded to the initial position by the compression spring 231. When the middle button is pressed, the synchronous pressing rod 240 presses the first locking tongue 235 and the second locking tongue 238 downward at the same time, and the two elastic links corresponding to the first locking tongue 235 and the second locking tongue 238 are separated from the first locking tongue 235 and the second locking tongue 238, and after the pressing is completed, the two compression springs 231 rebound so that the first locking tongue 235 and the second locking tongue 238 and the middle button return to the initial state. With this structural design, setting the first button and the second button can respectively control the first lock tongue 235 and the second lock tongue 238 and thus control the armrest extension mechanism 200 to open in different ways, while setting the middle button can simultaneously control the first lock tongue 235 and the second lock tongue 238 to open the armrest extension mechanism 200.

[0093] The implementation of this embodiment also discloses a vehicle armrest assembly, wherein the armrest extension mechanism 200 can switch between a retracted state, a semi-extended state, and an extended state relative to the armrest body 100. When the two elastic connecting rods 221 are in the folded state at the same time, the end cover 210 abuts against one side of the armrest body 100, and the armrest extension mechanism 200 is in the retracted state.

[0094] When one of the two elastic links 221 is unlocked from the lock tongue of the corresponding elastic lock, the two elastic links 221 are in a semi-open state, and the two elastic links 221 are in an inverted "L" shape, the end cover 210 is away from the armrest body 100 and is located closer to the side where one of the two elastic links 221 is located, and the armrest extension mechanism 200 is in a semi-extended state. When the two elastic links 221 are separated from the first lock tongue 235 and the second lock tongue 238 and are in an open state, the end cover 210 extends out of the front end of the armrest body 100.

[0095] More specifically, the semi-extended state is described, for example Figure 8 to Figure 10 The two elastic connecting rods 221 in the embodiment are respectively a left elastic connecting rod 2211 and a right elastic connecting rod 2212, wherein the left elastic connecting rod 2211 is correspondingly arranged on one side of the first button 233, and the right elastic connecting rod 2212 is correspondingly arranged on one side of the second button 236, see Figure 8 When the first button 233 and the second button 236 are all turned on (or the middle button 239 is pressed), and the left elastic link 2211 and the right elastic link 2212 are separated from the first locking tongue 235 and the second locking tongue 238 and are in an open state, the armrest extension mechanism 200 is in an extended state.

[0096] When the first button 233 is opened and the second button 236 is closed, the left elastic link 2211 and the first locking tongue 235 are separated and in a semi-open state, and the right elastic link 2212 and the second button 236 are closed. Fig. 9 , the two elastic links 221 are both in a semi-open state, and the two elastic links 221 are in an inverted "L" shape, and the open end cover 210 is more biased towards the left elastic link 2211, so it is convenient for passengers sitting on the left elastic link 2211 side to use. When the second button 236 is turned on and the first button 233 is turned off, the right elastic link 2212 and the second locking tongue 238 are separated and in a semi-open state, and the left elastic link 2211 and the first button 233 are closed, see Fig.10 , both elastic links 221 are in a semi-open state, and the two elastic links 221 are inverted "L" shapes, and the opened end cover 210 is more biased toward the right elastic link 2212, so it is convenient for passengers sitting on the right elastic link 2212 side to use.

[0097] By adopting the above technical solution, the armrest extension mechanism 200 can switch between a retracted state, a semi-extended state, and an extended state relative to the armrest body 100, thereby providing more usage scenarios and making it more convenient to use the armrest extension mechanism 200 in different states.

[0098] The implementation method of this embodiment also discloses a vehicle armrest assembly, see Figure 1 and Figure 2 The end cover 210 includes an end cover body 211 and two support ears 212 arranged on the end cover body 211. The end cover body 211 is adapted to the end shape of the armrest body 100, and the two support ears 212 are arranged at intervals along the end cover body 211.

[0099] By adopting the above technical solution, the support ear 212 can act as a hook, and two support ears 212 are provided to provide more application scenarios.

[0100] The implementation method of this embodiment also discloses a vehicle armrest assembly, see Figure 2 The armrest body 100 includes an armrest frame 110 and an armrest housing 120. A switch mounting groove 140 is provided on the upper surface of the armrest housing 120. The first button 233, the second button 236, and the middle button 239 of the switch assembly are all provided in the switch mounting groove 140 and exposed from the switch mounting groove 140. A storage groove 130 is also provided at one end of the armrest body 100 away from the vehicle body. When the armrest extension mechanism 200 is in a retracted state, the end cover 210 is received in the storage groove 130.

[0101] In summary, the present invention discloses an automobile armrest assembly, including an armrest body 100 and an armrest extension mechanism 200 that can be extended on the armrest body 100. When the armrest body 100 is flipped open relative to the vehicle body, the armrest extension mechanism 200 can extend out of the armrest body 100 from one end of the armrest body 100 away from the vehicle body. After the armrest extension mechanism 200 is extended and opened, it has a multifunctional auxiliary function. For example, a bag of goods or a garbage bag can be hung at the end cover 210, and the opened end cover 210 and the armrest body 100 can also be used as a bracket to place a mobile phone or a tablet for use. The extended end cover 210 can be used for multiple purposes, which solves the problem of inconvenient placement of bags of goods, mobile phones, etc. for rear passengers. And when the armrest extension mechanism 200 is not in use, it is equivalent to a part of the armrest body 100, and can be easily folded on the vehicle body or the rear seat, which is the same as a common flip armrest. In addition, by setting an elastic lock and an elastic connecting rod 221 to cooperate with each other, the armrest extension mechanism 200 can switch between a retracted state, a semi-extended state, and an extended state relative to the armrest body 100, thereby providing more usage scenarios, making it more convenient to use the armrest extension mechanism 200 in different states.

[0102] Example 2

[0103] The implementation method of this embodiment discloses a car, including any one of the car armrest assemblies disclosed in Example 1. Preferably, the car armrest assembly in this embodiment is located in the middle of the back of the rear seat of the car, and the car armrest assembly can be rotated and opened relative to the back of the rear seat. When rotated and opened, it becomes a middle armrest, and when closed, it becomes a part of the rear seat.

[0104] Specifically, the use of the armrest extension mechanism 200 in the vehicle armrest assembly in this embodiment is described as follows. Figure 3 As shown, this is a schematic diagram of the structure when the armrest extension mechanism 200 is not opened, for example Figure 8 to Figure 10 The two elastic connecting rods 221 in the embodiment are respectively a left elastic connecting rod 2211 and a right elastic connecting rod 2212, wherein the left elastic connecting rod 2211 is correspondingly arranged on one side of the first button 233, and the right elastic connecting rod 2212 is correspondingly arranged on one side of the second button 236, see Figure 8 When the first button 233 and the second button 236 are all turned on (or the middle button 239 is pressed), and the left elastic link 2211 and the right elastic link 2212 are separated from the first locking tongue 235 and the second locking tongue 238 and are in an open state, the armrest extension mechanism 200 is in an extended state.

[0105] When the first button 233 is opened and the second button 236 is closed, the left elastic link 2211 and the first locking tongue 235 are separated and in a semi-open state, and the right elastic link 2212 and the second button 236 are closed. Fig. 9 , the two elastic links 221 are both in a semi-open state, and the two elastic links 221 are in an inverted "L" shape, and the open end cover 210 is more biased towards the left elastic link 2211, so it is convenient for passengers sitting on the left elastic link 2211 side to use. When the second button 236 is turned on and the first button 233 is turned off, the right elastic link 2212 and the second locking tongue 238 are separated and in a semi-open state, and the left elastic link 2211 and the first button 233 are closed, see Fig.10 , both elastic links 221 are in a semi-open state, and the two elastic links 221 are inverted "L" shapes, and the opened end cover 210 is more biased toward the right elastic link 2212, so it is convenient for passengers sitting on the right elastic link 2212 side to use.
