[0002] The automobile armrest is a kind of automobile accessory installed between two seats and belongs to the interior system of the automobile. Taking the armrest of the rear row of seats as an example, the armrest of the rear row of seats is arranged in a reversible and openable manner in the rear row of seats of the automobile, which can improve the riding experience of the passengers in the rear row of seats and ultimately achieve the purpose of improving the market competitiveness.

[0003] Many structures or functions have been integrated into the armrest of the rear row of seats in the prior art, such as arranging a cup holder, a cup holder, etc. in the armrest of the rear row of seats, or arranging a storage compartment in the armrest of the rear row of seats, etc. However, the cup holder and the storage compartment are fixedly arranged on the armrest of the rear row of seats. When the passengers in the rear row of seats have a bag or a garbage bag, there is a lack of a hook assembly that can be used. When using a mobile phone or a tablet, etc., there is also a problem that the mobile phone or the tablet cannot be placed as a support. Therefore, the armrest of the rear row of seats that can be reversibly opened in the prior art has the problems of being unable to provide a hook and being unable to serve as a support. SUMMARY

[0004] The purpose of the present application is to solve the problem that the armrest of the rear row of seats that can be reversibly opened in the prior art cannot provide a hook and cannot serve as a support.

One end of the armrest body is rotatably connected to the vehicle body, and the armrest extension mechanism can extend out of the armrest body from the other end of the armrest body. The armrest extension mechanism comprises an end cover, a linkage assembly and a locking assembly. One end of the linkage assembly is rotatably connected to the armrest body, the other end is rotatably connected to the end cover, and the linkage assembly is switched 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 the folded state or the open state, respectively.

[0006] When the linkage assembly is in the folded state relative to the armrest body and is locked by the locking assembly, the end cover abuts and covers the corresponding area of the end of the armrest body.

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

[0062] Embodiment 1

[0063] The embodiment discloses an automobile armrest assembly, please refer to Figure 1 and Figure 2 , comprising an armrest body 100 and an armrest extension mechanism 200 arranged on the armrest body 100 in an extendable manner, one end of the armrest body 100 is rotatably connected to a vehicle body (not shown in the figure), and the armrest extension mechanism 200 can extend 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, 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 the folded state or the open state respectively.

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

[0065] Specifically, in this embodiment, the automobile armrest assembly is arranged on the backrest of the rear seat of the automobile, and is located in the middle of the backrest and is rotatably connected to the backrest through a rotating shaft or a pin shaft. When the armrest needs to be opened, the armrest assembly is rotated to open it. After opening, the armrest extension mechanism 200 needs to be used, and the linkage assembly 220 is unlocked relative to the armrest body 100 by the locking assembly 230 to be used in the open state. At this time, the end cover 210 extends forward away from the side of the backrest, and when the use is finished, the linkage assembly 220 is locked by the locking assembly 230 and the end cover 210 abuts against the corresponding area covering the end of the armrest body 100. When the armrest is not used, the automobile armrest assembly is turned over to become part of the backrest.

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

[0067] And, 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, and after the armrest extension mechanism 200 is extended open, it has a multifunctional auxiliary function, for example, it can hang an article bag or a garbage bag at the end cover 210, or it can use the open end cover 210 and the armrest body 100 to cooperate to serve as a support to rest a mobile phone or a tablet for use. The extended end cover 210 can serve multiple purposes, solving the problem of inconvenient placement of article bags, mobile phones, etc. of rear passengers. And when not in use, the armrest extension mechanism 200 is equivalent to part of the armrest body 100, and can be conveniently folded on the vehicle body or rear seat, which is the same as the commonly seen foldable armrest.

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

[0069] The embodiment of the present application also discloses an automobile armrest assembly, wherein the linkage assembly 220 includes a linkage component that can be folded relative to the armrest body 100. When the linkage component is in a folded state relative to the armrest body 100, the linkage component is compressed and has an elastic compression force; when the locking assembly 230 releases the locking of the linkage component, the elastic compression force pushes the linkage component to unfold and drive the end cover 210 away from the end of the armrest body 100. The linkage component is any one of a pivot linkage, an elastic linkage, or a scissor linkage.

[0070] Specifically, taking the pivot linkage as an example, the pivot linkage is provided with at least two sections and a middle part of the pivot linkage is provided as a pivot 224, so that the pivot linkage can be folded or unfolded; the elastic linkage is similar to the pivot linkage and can switch between a folded state and an unfolded state, and also has an elastic force in the folded state; and the scissor linkage can also be folded or unfolded, and when a spring, a coil spring, or the like is arranged on a middle pivot of the scissor linkage, the scissor linkage has an elastic compression force in the folded state, so that after the locking is released, the scissor linkage can automatically unfold and move away from the end of the armrest body 100. By arranging the linkage component that can be folded and has an elastic compression force, the end cover 210 can be conveniently controlled to be folded or unfolded, and after the linkage component is folded to drive the end cover 210 to be folded and locked by the locking assembly 230, the linkage component has an elastic compression force, and after the locking assembly 230 releases the locking, the linkage component drives the end cover 210 to be unfolded relative to the armrest body 100.

[0071] Next, the specific structure of the locking assembly 230 will be described. The locking assembly 230 includes a resilient lock catch provided on the armrest body 100. The resilient lock catch includes a lock tongue that extends from the armrest body 100 toward the linkage member and is movable relative to the armrest body 100 to lock / unlock the linkage member. The resilient lock catch can be reused and automatically reset after being pressed, and then the linkage member is locked by the lock tongue.

[0072] Please refer to Figure 1 and Figure 2 , the linkage member includes a pair of resilient linkages 221, which are respectively provided on both sides of the armrest body 100 in the width direction.

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

[0074] Specifically, for the case where at least one or all of the pair of resilient linkages 221 is in the open state, the resilient linkage 221 drives the end cover 210 away from the end of the armrest body 100, as shown in Figure 3 , at this time the end cover 210 is part of the armrest body 100. As shown in Figure 8 , when both resilient linkages 221 are fully open, the armrest extension mechanism 200 is in a fully open state, as shown in Figure 9 , when the left resilient linkage 221 is open, the armrest extension mechanism 200 is half open and the open end cover 210 is closer to the left side, as shown in Figure 10 , when the right resilient linkage 221 is open, the armrest extension mechanism 200 is half open and the open end cover 210 is closer to the right side.

[0075] With this structure, the resilient linkages 221 are provided, and when both resilient linkages 221 are in the folded state and locked by the resilient lock catch, the end cover 210 is closed relative to the armrest body 100 and forms part of it, and the resilient linkages 221 also have elastic compression force and can drive the end cover 210 to automatically open after being unlocked.

[0076] Further details of the structure of the resilient linkages 221 will be described, please refer to Figure 4Each elastic connecting rod 221 comprises a first rod portion 222, a second rod portion 223, a rotating shaft 224 and an elastic reset member 225.

[0077] The respective 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 periphery of the rotating shaft 224, and the two ends of the elastic reset member 225 abut against the respective ends of 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 with the handrail body 100, and the other end of the other one is rotatably connected with the end cover 210. When the first rod portion 222 and the second rod portion 223 are in the folded state, the elastic reset member 225 is in the compressed state. The elastic reset member 225 can be a common reset spring, a compression spring, a coil spring, etc.

[0078] Specifically, please refer to Figure 4 and Figure 5 In the embodiment, the ends of the first rod portion 222 and the second rod portion 223 rotatably connected are provided with two rotating sleeve-connected rotating shafts 224, and further have a cavity portion in which the elastic reset member 225 is sleeved in the rotating shaft 224. It can be understood that those skilled in the art can also sleeve the elastic reset member 225 on the outer periphery of the rotating shaft 224 in other ways or adopt other rotatable connection modes, which are not specifically limited in the embodiment. Through the design of such 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, at which time the elastic connecting rod 221 also has elastic compression force.

[0079] Further description of the specific structure of the elastic reset member 225 will be given, please refer to Figure 4 The elastic reset member 225 comprises a torsion spring, the torsion spring comprises a spring body 226 sleeved on the outer periphery of the rotating shaft 224 and two clamping legs 227 extendedly arranged at the two ends of the spring body 226, and the two clamping legs 227 abut against the respective ends of the first rod portion 222 and the second rod portion 223, respectively. And, as shown in Figure 5 and Figure 6 When the elastic connecting rod 221 is in the folded state, the torsion spring is in the torsion compression state; as shown in Figure 4 When the elastic connecting rod 221 is in the unfolded state, the torsion spring is in the reset state.

[0080] With this arrangement, the two clamping legs 227 of the torsion spring are respectively arranged at the corresponding ends of the first and second rod portions 222 and 223. When the first and second rod portions 222 and 223 are folded, the two clamping legs 227 abutting the first and second rod portions 222 and 223 are also deformed, and the spring body 226 is also deformed. At this time, the spring body 226 also has elastic potential energy, and the elastic potential energy is transmitted to the first and second rod portions 222 and 223. When the locking assembly 230 is locked, the first and second rod portions 222 and 223 are folded together. When the locking assembly 230 is unlocked, the first and second rod portions 222 and 223 are opened under the action of the torsion spring.

[0081] Further referring to Figure 5 When each elastic connecting rod 221 is in the folded state, the first and second rod portions 222 and 223 are folded towards each other and form a "two" shape as a whole, and the elastic reset member 225 is in a compressed state. Further referring to Figure 6 When the two elastic connecting rods 221 are in the folded state, the rotation shafts 224 of the two elastic connecting rods 221 are arranged opposite to each other, that is, the two elastic connecting rods 221 are folded towards each other with the rotation shafts 224 opposite to each other. Only in this way, the first and second rod portions 222 and 223 of the two elastic connecting rods 221 can be folded towards each other and located at one end of the armrest body 100.

[0082] Further referring to Figure 4 When each elastic connecting rod 221 is in the unfolded state, the first and second rod portions 222 and 223 extend in the same direction and form a "one" shape as a whole, and the elastic reset member 225 is in a reset state. Further referring to Figure 9 and Figure 10 Each elastic connecting rod 221 can also be in a semi-unfolded state. When the elastic connecting rod 221 is in the semi-unfolded state, the first and second rod portions 222 and 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. Because the elastic connecting rod 221 in this embodiment has multiple unfolding modes, the corresponding end cover 210 can also be unfolded and present different states.

[0083] Further referring to Figure 4 and Figure 5, the first rod portion 222 and the second rod portion 223 are provided with a plurality of lightening cavities 228 arranged at intervals. The first rod portion 222 and the second rod portion 223 are provided with a plurality of abutting portions 229 on the side close to each other in the folded state of the elastic connecting rod 221, the abutting portions 229 on the first rod portion 222 and the second rod portion 223 are respectively arranged at intervals and are staggered, and the first rod portion 222 and the second rod portion 223 extend parallel to each other in the folded state of the elastic connecting rod 221. With this design scheme, the plurality of lightening holes can reduce the weight of the first rod portion 222 and the second rod portion 223, and as shown in Figure 4 and Figure 5 , the first rod portion 222 and the second rod portion 223 can each be provided with two abutting portions 229, and those skilled in the art can set three, four or even more according to actual needs. The plurality of abutting portions 229 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 will be described with reference to Figure 2 and Figure 7 , the locking assembly 230 includes a pair of elastic latches corresponding to the pair of elastic connecting rods 221 respectively. Each elastic latch includes a lock tongue extending from the handrail body 100 towards the elastic connecting rod 221, a compression spring 231 is arranged at the bottom of the lock tongue and inside the handrail 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 handrail body 100 is provided with a clamping groove matched with the hook 232, and the hook 232 and the clamping groove are matched and connected when the elastic connecting rod 221 is in the folded state.

[0086] With this structure, the elastic latches are arranged, and when the first rod portion 222 and the second rod portion 223 are locked by the cooperation of the hook 232 and the clamping groove, the elastic force provided by the compression spring 231 abutting the lock tongue prevents the hook 232 and the clamping groove from being separated by external force.

[0087] It should be noted that, as shown in Figure 6 , although the hook 232 of the lock tongue is connected to only one of the first rod portion 222 and the second rod portion 223, the pivot shafts 224 are arranged opposite to each other when the two elastic connecting rods 221 are folded, and the other end of the two elastic connecting rods 221 is connected to the end cover 210 at the same time, so the end cover 210 limits the two elastic connecting rods 221, and the hook 232 of the lock tongue only limits one rod portion to achieve the folding and fixing of the elastic connecting rod 221.

[0088] Further, as shown in Figure 7The locking assembly 230 further comprises a switch assembly arranged on the handrail body 100, which comprises a first button, an intermediate button and a second button arranged in sequence.

[0089] The first button comprises a first key 233 exposed on the handrail body 100 and a first pressing rod 234 arranged at the bottom of the first key 233, the end of the first pressing rod 234 abuts against the top of a first locking tongue 235.

[0090] The second button comprises a second key 236 exposed on the handrail body 100 and a second pressing rod 237 arranged at the bottom of the second key 236, the end of the second pressing rod 237 abuts against the top of a second locking tongue 238.

[0091] The intermediate button comprises an intermediate key 239 and a synchronous pressing rod 240 arranged at the bottom of the intermediate key 239 and extending towards the first locking tongue 235 and the second locking tongue 238 respectively, the end of the synchronous pressing rod 240 abuts against the top of the first locking tongue 235 and the second locking tongue 238 simultaneously.

[0092] The pressing process of the switch assembly is briefly described as follows: for example, when the first key 233 is pressed, the first key 233 drives the first pressing rod 234 at the bottom to move downwards and drives the first locking tongue 235 to move downwards, at this time, the clamping hook 232 of the first locking tongue 235 and the clamping groove on the elastic connecting rod 221 are separated, and the compression spring 231 at the bottom is compressed, after the pressing is completed, the corresponding elastic connecting rod 221 clamped by the first locking tongue 235 is separated from the locking tongue, and the locking tongue and the first key 233 are bounced to the initial position by the compression spring 231. Similarly, when the second key 236 is pressed, the second key 236 drives the second pressing rod 237 at the bottom to move downwards and drives the second locking tongue 238 to move downwards, at this time, the clamping hook 232 of the second locking tongue 238 and the clamping groove on the elastic connecting rod 221 are separated, and the compression spring 231 at the bottom is compressed, after the pressing is completed, the corresponding elastic connecting rod 221 clamped by the second locking tongue 238 is separated from the locking tongue, and the locking tongue and the second key 236 are bounced to the initial position by the compression spring 231. When the intermediate button is pressed, the synchronous pressing rod 240 simultaneously presses the first locking tongue 235 and the second locking tongue 238 downwards, the two elastic connecting rods corresponding to the clamping of 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 bounce to restore the first locking tongue 235, the second locking tongue 238 and the intermediate button to the initial state. By adopting this structure design, the first button and the second button can be arranged to control the first locking tongue 235 and the second locking tongue 238 respectively to control the handrail extension mechanism 200 to open in different ways, and the intermediate button can be arranged to control the first locking tongue 235 and the second locking tongue 238 simultaneously to open the handrail extension mechanism 200.

[0093] The implementation manner of the embodiment also discloses an automobile armrest assembly. The armrest extension mechanism 200 can be switched between the retracted state, the half-extended state and the 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 connecting rods 221 is unlocked with the locking tongue of the corresponding elastic lock catch, the two elastic connecting rods 221 are in the half-opened state and are in the inverted “L” shape relative to each other, the end cover 210 is away from the armrest body 100 and is located at a position closer to the side where one of the two elastic connecting rods 221 is located, and the armrest extension mechanism 200 is in the half-extended state. When the two elastic connecting rods 221 are separated from the first locking tongue 235 and the second locking tongue 238 and are in the opened state, the end cover 210 extends from the front end of the armrest body 100.

[0095] More specifically, the half-extended state is described as follows. Figures 8-10 In the half-extended state, the two elastic connecting rods 221 are a left elastic connecting rod 2211 and a right elastic connecting rod 2212, wherein the left elastic connecting rod 2211 is arranged on one side of the first button 233, and the right elastic connecting rod 2212 is arranged on one side of the second button 236, as shown in FIG. 2. Figure 8 When the first button 233 and the second button 236 are all opened (or the middle button 239 is pressed), and the left elastic connecting rod 2211 and the right elastic connecting rod 2212 are separated from the first locking tongue 235 and the second locking tongue 238 and are in the opened state, the armrest extension mechanism 200 is in the extended state.

[0096] When the first button 233 is opened and the second button 236 is closed, the left elastic connecting rod 2211 is separated from the first locking tongue 235 and is in the half-opened state, and the right elastic connecting rod 2212 is closed with the second button 236, as shown in FIG. 3. Figure 9 The two elastic connecting rods 221 are in the half-opened state and are in the inverted “L” shape relative to each other, and the opened end cover 210 is more inclined to the left elastic connecting rod 2211, so as to facilitate the use of a passenger sitting on the side of the left elastic connecting rod 2211. When the second button 236 is opened and the first button 233 is closed, the right elastic connecting rod 2212 is separated from the second locking tongue 238 and is in the half-opened state, and the left elastic connecting rod 2211 is closed with the first button 233, as shown in FIG. 4. Figure 10 The two elastic connecting rods 221 are in the half-opened state and are in the inverted “L” shape relative to each other, and the opened end cover 210 is more inclined to the right elastic connecting rod 2212, so as to facilitate the use of a passenger sitting on the side of the right elastic connecting rod 2212.

[0097] The handrail extension mechanism 200 can be switched between the retracted state, the half-extended state and the extended state relative to the handrail body 100, thereby providing more use scenarios and making it more convenient to use the handrail extension mechanism 200 in different states.

[0098] The embodiment also discloses an automobile handrail assembly, which refers to Figure 1 and Figure 2 The end cover 210 comprises an end cover body 211 and two support ears 212 arranged on the end cover body 211. The end cover body 211 is matched with the shape of the end of the handrail body 100, and the two support ears 212 are arranged at intervals along the end cover body 211.

[0099] The support ears 212 can function as hooks, and two support ears 212 are arranged to provide more application scenarios.

[0100] The embodiment also discloses an automobile handrail assembly, which refers to Figure 2 The handrail body 100 comprises a handrail framework 110 and a handrail shell 120. The upper surface of the handrail shell 120 is provided with a switch mounting groove 140. The first button 233, the second button 236 and the middle button 239 of the switch assembly are arranged in the switch mounting groove 140 and exposed from the switch mounting groove 140. The end of the handrail body 100 away from the vehicle body is also provided with a receiving groove 130. When the handrail extension mechanism 200 is in the retracted state, the end cover 210 is accommodated in the receiving groove 130.

[0101] In summary, the application discloses an automobile handrail assembly, which comprises a handrail body 100 and a handrail extension mechanism 200 arranged on the handrail body 100 in an extendable manner. When the handrail body 100 is flipped open relative to the vehicle body, the handrail extension mechanism 200 can be extended from the end of the handrail body 100 away from the vehicle body. After the handrail extension mechanism 200 is extended and opened, it has a multifunctional auxiliary function, for example, an article bag or a garbage bag can be hung at the end cover 210, and the opened end cover 210 and the handrail body 100 can be used as a support to place a mobile phone or a tablet computer. The extended end cover 210 can be used in multiple ways, solving the problem that it is inconvenient to place an article bag, a mobile phone and the like of a rear passenger. When the handrail extension mechanism 200 is not used, it is equivalent to part of the handrail body 100 and can be conveniently folded on the vehicle body or the rear seat, which is the same as a common flipable handrail. The elastic lock and the elastic connecting rod 221 are arranged to cooperate with each other, so that the handrail extension mechanism 200 can be switched between the retracted state, the half-extended state and the extended state relative to the handrail body 100, thereby providing more use scenarios and making it more convenient to use the handrail extension mechanism 200 in different states.

Preferably, the car armrest assembly in this embodiment is located in the middle of the back of the rear seat of the car. The car armrest assembly can be rotated open relative to the back of the rear seat. When rotated open, it is a central armrest, and when closed, it is part of the rear seat.

[0104] Specifically, the usage of the armrest extension mechanism 200 in the automotive armrest assembly of this embodiment will be described, such as... Figure 3 As shown, this is a schematic diagram of the handrail extension mechanism 200 when it is not open. Figures 8-10 The two elastic links 221 are the left elastic link 2211 and the right elastic link 2212, respectively. The left elastic link 2211 is located on one side of the first button 233, and the right elastic link 2212 is located on one side of the second button 236. See [link to relevant documentation]. Figure 8 When the first button 233 and the second button 236 are both open (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 the open state, the handrail extension mechanism 200 is in the 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, while the right elastic link 2212 and the second button 236 are closed. (See below) Figure 9 Both elastic links 221 are in a semi-open state, and the two elastic links 221 are in an inverted "L" shape. At this time, the opened end cap 210 is more biased towards the left elastic link 2211, thus facilitating use by the passenger seated on the left side of the elastic link 2211. When the second button 236 is opened and the first button 233 is closed, the right elastic link 2212 and the second locking tongue 238 separate and are in a semi-open state, while the left elastic link 2211 and the first button 233 are closed. (See [reference]). Figure 10 Both elastic links 221 are in a semi-open state and are in an inverted "L" shape. At this time, the open end cap 210 is more biased towards the right elastic link 2212, which makes it convenient for passengers sitting on the right side of the elastic link 2212 to use.
