Description

Technical Field

[0001] The present invention particularly relates to an armrest assembly and a vehicle having the same. Background Art

[0002] Some vehicles are equipped with an armrest assembly that can be flipped open in both directions. Such an armrest assembly is usually located between two vehicle seats (for example, the main driver's seat and the co-driver's seat), and two unlocking buttons are provided on it, one on the left and one on the right; when the unlocking button located on the left part of the armrest assembly is pressed, the armrest cover of the armrest assembly can flip open a small angle from left to right (or receive an auxiliary force that enables it to flip from left to right); when the unlocking button located on the right part of the armrest assembly is pressed, the armrest cover of the armrest assembly can flip open a small angle from right to left (or receive an auxiliary force that enables it to flip from right to left).

[0003] Based on the above, the configuration that allows such an armrest assembly to be able to flip open to a small angle or be subjected to a certain opening auxiliary force after being unlocked is as follows: such an armrest assembly includes two torsion springs respectively arranged on the left and right parts of the armrest assembly, and the two torsion springs are pre-tightened when the armrest assembly is in a locked state, that is, they store elastic potential energy; at least one of the two torsion springs can release the stored elastic potential energy at the moment the armrest assembly is unlocked, push the armrest cover of the armrest assembly, and make the armrest cover bounce upward, thereby indicating to the occupant that the armrest assembly has been unlocked, and allowing the occupant to conveniently apply force to open the armrest cover.

[0004] The above-mentioned arrangement of the armrest assembly has the following disadvantages:

[0005] 1. The torsion spring is difficult to install and adjust;

[0006] 2. Since the torsion spring is difficult to install and adjust, the assembly process of the handrail assembly is complicated and requires high proficiency of the workers;

[0007] 3. Due to the high difficulty in adjusting the preload of the torsion spring (i.e. the difficulty of calibration), in the actual production process, the torsion springs of the same batch of handrail assemblies usually have poor consistency;

[0008] 4. Since the torsion spring is difficult to adjust and its torque will change greatly if there is a slight deviation in the installation, the actual thrust of the torsion spring on the armrest cover is often too large, which can easily cause the armrest cover to bounce up quickly and violently after the armrest assembly is unlocked, and then easily hit the occupants' hands, bringing a bad impact on the occupants' riding experience.

[0052] Embodiment 1

[0053] like Figure 1 and Figure 2 As shown, this embodiment provides a vehicle, wherein a sub-dashboard assembly is provided between the main driving seat and the co-driving seat of the vehicle, wherein the sub-dashboard assembly includes an armrest assembly, wherein the armrest assembly includes an armrest cover 1, a bottom frame 2 and an unlocking button 3, wherein the bottom frame 2 is approximately L-shaped with the opening facing downward, wherein the long side of the bottom frame 2 is arranged in the front-to-back direction, and the short side is arranged in the up-down direction. Figure 2 and Figure 3 As shown, a through area 21 is provided in the middle and rear part of the bottom frame 2. The through area 21 is covered when the armrest assembly is in a locked state, and is exposed to the passenger's visual range after the armrest assembly is unlocked and the armrest cover 1 is completely opened.

[0054] Please refer back to the above description Figure 1 and Figure 2 In this embodiment, a storage box (not shown in the figure, its position is about Figure 1 The unlocking button 3 is located at the position indicated by the middle arrow; the number of the unlocking buttons 3 is two, and the two unlocking buttons 3 are respectively exposed at the left and right parts of the armrest cover 1; when the unlocking button 3 located at the left part of the armrest cover 1 is pressed, the armrest assembly is unlocked, and the armrest cover 1 will flip over a small angle from left to right relative to the bottom frame 2 (or receive an auxiliary force that enables it to flip over from left to right), so that the occupant knows that the armrest assembly has been unlocked, and the occupant can open the armrest cover 1 to expose the aforementioned through-area 21 leading to the storage box, so as to operate the storage box; similarly, when the unlocking button 3 located at the right part of the armrest cover 1 is pressed, the armrest assembly is unlocked, and the armrest cover 1 will flip over a small angle from right to left (or receive an auxiliary force that enables it to flip over from right to left), so that the occupant knows that the armrest assembly has been unlocked, and the occupant can open the armrest cover 1 to expose the aforementioned through-area 21 leading to the storage box, so as to operate the storage box.

[0055] What is particularly special in this embodiment is that Figure 4 and Figure 5As shown, in addition to the above-mentioned armrest cover 1, bottom frame 2 and unlocking button 3, the armrest assembly also includes a mounting plate 4, a locking rod 5, a coil spring 6 and a cover body 7, wherein the armrest cover 1, the cover body 7 and the mounting plate 4 are configured as the parts that are turned over after the armrest assembly is unlocked (also the parts that cover the through area 21 together when the armrest assembly is locked), and the bottom frame 2 is configured as the part that is fixed after the armrest assembly is unlocked; the front and rear ends of the bottom frame 2 are respectively provided with a first matching portion 22 (please refer to Figure 3 ) and the second matching portion 23, the mounting plate 4 is located between the first matching portion 22 and the second matching portion 23, the armrest cover 1 is covered on the cover body 7, the cover body 7 includes a force-bearing end cover 71 located on the second matching portion 23, the coil spring 6 is located between the second matching portion 23 and the force-bearing end cover 71, and is configured to be in an elastic deformation state when the armrest assembly is locked; the coil spring 6 is used to apply a force parallel to its axial direction to the force-bearing end cover 71 to push the armrest cover 1.

[0056] In addition, the aforementioned unlocking button 3 can be slidably set on the mounting plate 4; the aforementioned locking rod 5 is connected to the mounting plate 4, and the locking rod 5 can be slidably set in the armrest assembly and can rotate relative to the first matching portion 22; the unlocking button 3 can make at least a part of the locking rod 5 in the armrest assembly withdraw from or insert into the first matching portion 22 to unlock or lock the armrest assembly.

[0057] As can be seen from the above, the present embodiment overcomes the conventional design concept of the armrest assembly, and does not provide a torsion spring to push the armrest cover 1 after the armrest assembly is unlocked. Instead, a coil spring 6 that can apply a force parallel to its own axial direction to the armrest cover 1 is used; since the armrest cover 1 is covered on the cover body 7, the force-bearing end cover 71 belonging to the cover body 7 is located on the second matching portion 23, and the coil spring 6 is located between the second matching portion 23 and the force-bearing end cover 71. Therefore, it is obvious that the coil spring 6 only needs to be in a compressed state between the second matching portion 23 and the force-bearing end cover 71 when the armrest assembly is locked, and the installation difficulty and adjustment difficulty are both relatively low.

[0058] Furthermore, since the installation and adjustment difficulty of the coil spring 6 is low, the cumbersomeness of the assembly process of the armrest assembly is indirectly reduced. Furthermore, under the premise of ensuring low adjustment cost and high assembly process efficiency, the armrest assemblies using the coil spring 6 are more likely to have good consistency.

[0059] Based on the above, it is obvious that as long as the appropriate expected design is carried out, the armrest assembly in this embodiment is less likely to have the situation described in the background technology where the armrest cover 1 bounces upward too violently and hits the occupant's hand.

[0060] The following is a more detailed exemplary configuration of the armrest assembly in this embodiment:

[0061] Please continue reading Figure 4 and Figure 5 In this embodiment, the first matching portion 22 and the second matching portion 23 are special-shaped bodies that protrude upward relative to their circumferential sides; in addition to the force-bearing end cover 71, the cover body 7 in this embodiment also includes a main body 72 and a follower end cover 73, wherein the follower end cover 73 and the force-bearing end cover 71 are respectively located on the front and rear sides of the main body 72, and are connected to the main body 72 as a whole; the main body 72, the follower end cover 73 and the force-bearing end cover 71 are respectively arranged corresponding to the mounting plate 4, the first matching portion 22 and the second matching portion 23; after the bottom frame 2, the mounting plate 4, the cover body 7 and the armrest cover 1 are assembled, the armrest cover 1 is buckled on the entire cover body 7, the follower end cover 73 is covered on the first matching portion 22 and is provided with a hole for the locking rod 5 to enter and exit, the force-bearing end cover 71 is covered on the second matching portion 23, and the main body 72 is located below the mounting plate 4.

[0062] Exemplarily, the main body 72 is provided with a plurality of clamp heads 721 extending upward relative to its upper surface, and the mounting plate 4 is provided with a plurality of clamping grooves 41 for one-to-one matching with the clamp heads 721. After the cover body 7, the armrest cover 1, and the mounting plate 4 are assembled, the cover body 7 and the mounting plate 4 are fixed together by the matching between the clamp heads 721 and the clamping grooves 41, and bolts (not shown) are sequentially penetrated into the mounting plate 4 and the armrest cover 1 from bottom to top. Of course, those skilled in the art can flexibly set the specific connection method between the armrest cover 1, the cover body 7, and the mounting plate 4 as needed.

[0063] Based on the above-mentioned matching relationship between the second matching portion 23 and the force-bearing end cover 71, please continue to refer to Figure 6 and Figure 7 ; Exemplarily, a receiving area 231 for accommodating the coil spring 6 is provided on the second matching portion 23, and the armrest assembly also includes a buffer block 8, which can slide axially along the aforementioned coil spring 6 in the receiving area 231; a portion of the buffer block 8 protrudes out of the upper surface of the second matching portion 23 (i.e., the surface facing the force-bearing end cover 71), and the middle portion of the buffer block 8 is partially hollowed out.

[0064] In order to accommodate the coil spring 6 more stably, a protrusion 2311 is provided in the accommodation area 231, and one end of the coil spring 6 is sleeved on the protrusion 2311 and contacts the solid part located on the periphery of the protrusion 2311 in the accommodation area 231, while the other end of the coil spring 6 extends into the middle of the buffer block 8 and contacts the buffer block 8; the coil spring 6 is equivalent to being located between the part of the buffer block 8 and the periphery of the protrusion 2311. In this embodiment, the coil spring 6 is configured to abut against the periphery of the protrusion 2311 and the buffer block 8 when the armrest assembly is locked; in this way, when the armrest assembly is locked, the coil spring 6 is in a compressed state with stored elastic potential energy; after the armrest assembly is unlocked, since the protrusion 2311 belonging to the bottom frame 2 is fixed, the coil spring 6 can push the buffer block 8 with the stored elastic potential energy, so that the buffer block 8 moves upward and protrudes more out of the upper surface of the second matching portion 23, thereby indirectly pushing the armrest cover 1.

[0065] Of course, the form in which the coil spring 6 contacts the buffer block 8 and the circumferential side of the protrusion 2311 in the accommodating area 231 can be flexibly set by those skilled in the art and is not limited to the form exemplified in this embodiment.

[0066] Based on the above, in order to ensure the sliding stability of the buffer block 8 in the accommodating area 231, and to ensure that the buffer block 8 will not fall out of the accommodating area 231 as a whole when the coil spring 6 pushes the buffer block 8, a feature portion 81 is further provided on the buffer block 8 in this embodiment, and the feature portion 81 is in a protruding posture outward relative to its surrounding portion; correspondingly, a track 2312 is provided in the accommodating area 231, and the track 2312 is slidably matched with the feature portion 81, and is arranged along the axial direction (i.e., the up and down direction) of the coil spring 6, and its upper end (i.e., the end closest to the force-bearing end cover 71) is located below the upper surface of the second matching portion 23 (i.e., the surface facing the force-bearing end cover 71).

[0067] In this way, even if the buffer block 8 moves upward due to the drive of the coil spring 6, since the highest point of the track 2312 is located below the upper surface of the second matching portion 23, the highest point of the stroke of the characteristic portion 81 is naturally also located below the upper surface of the second matching portion 23. The characteristic portion 81 will not be separated from the track 2312 due to the pushing of the coil spring 6, and the buffer block 8 will not be separated from the second matching portion 23 as a whole due to the pushing of the coil spring 6.

[0068] Exemplarily, the buffer block 8 in this embodiment is a rubber product; since a portion of the buffer block 8 protrudes out of the second matching portion 23, the coil spring 6 does not directly contact the force-bearing end cover 71. Therefore, in the process of the armrest cover 1 turning from fully open to flipping down and resetting, the setting of the buffer block 8 can ensure that the armrest cover 1 closes with a small sound; when the armrest assembly is locked, the coil spring 6 can also support the cover body 7 and the armrest cover 1 through the buffer block 8, ensuring that there will not be too many collisions between the cover body 7 and the second matching portion 23.

[0069] Exemplarily, in this embodiment, there are two accommodating areas 231, buffer blocks 8 and coil springs 6, each of which forms a group of mechanisms for pushing the stressed end cover 71, and the left and right parts of the second matching part 23 are each provided with a group of such mechanisms.

[0070] Please refer back to Figure 5 and Figure 6 As mentioned above, the unlocking button 3 can drive at least a part of the locking rod 5 to withdraw or insert into the first matching portion 22 to unlock or lock the armrest assembly; to achieve this setting, the armrest assembly also includes a first type of rod 9 and a movable plate 10, each first type of rod 9 is connected to a locking rod 5, and the first type of rod 9 and the unlocking button 3 are arranged in a one-to-one correspondence; for the connected first type of rod 9 and locking rod 5, the first type of rod 9 carrying the locking rod 5 is slidably arranged at the front of the mounting plate 4, and the first type of rod 9 and the locking rod 5 are configured to slide in the front and rear directions; the movable plate 10 is connected to the unlocking button 3 and can also be slidably arranged at the front of the mounting plate 4, and the movable plate 10 and the unlocking button 3 are configured to slide in the left and right directions, and at least a portion of the movable plate 10 covers the first type of rod 9.

[0071] According to the above, a driving hole 101 is provided on the portion of the movable plate 10 covering the first type rod 9, and the driving hole 101 is an oblong hole extending obliquely from front to rear; correspondingly, a force transmission column 91 extending into the driving hole 101 is provided on the first type rod 9. In this embodiment, since the sliding track of the connected first type rod 9 and the locking rod 5 is perpendicular to the sliding track of the connected movable plate 10 and the unlocking button 3, the combination Figure 5 and Figure 6 It can be seen that the unlocking button 3 can drive the movable plate 10 to slide during its sliding process, so that the movable plate 10 drives the first type of rod 9 to slide backward or forward through the force transmission column 91, and the first type of rod 9 drives a part of the locking rod 5 to withdraw from or insert into the first matching part 22, thereby realizing the unlocking and locking of the armrest assembly.

[0072] As mentioned above, since there are two unlocking buttons 3 in this embodiment, there are two first-type rods 9 and movable plates 10 in total in this embodiment; specifically, one first-type rod 9 and one movable plate 10 are arranged at the left front part of the armrest assembly with one unlocking button 3, and another first-type rod 9 and another movable plate 10 are arranged at the right front part of the armrest assembly with the unlocking button 3. When the unlocking button 3 located at the left front part of the armrest assembly is pressed and the left part of the armrest assembly is unlocked, the armrest cover 1, the mounting plate 4 and the cover body 7 will turn over under the push of the coil spring 6 with the locking rod 5 connected to the first-type rod 9 located at the right part of the armrest assembly as the rotation axis; similarly, when the unlocking button 3 located at the right front part of the armrest assembly is pressed and the right part of the armrest assembly is unlocked, the armrest cover 1, the mounting plate 4 and the cover body 7 will turn over under the push of the coil spring 6 with the locking rod 5 connected to the first-type rod 9 located at the left part of the armrest assembly as the rotation axis.

[0073] Exemplarily, the locking rod 5 in this embodiment is inserted into the front end of the first type rod 9, the locking rod 5 is connected to the first type rod 9, and is rotatably connected to the first matching portion 22 through a bearing. It should be noted that there are multiple optional schemes for the specific connection method between the locking rod 5 and the first type rod 9: for example, optionally, the first type rod 9 is rotatably connected to the first matching portion 22 through a bearing, and the first type rod 9 and the locking rod 5 are threadedly matched; optionally, the locking rod 5 is rotatably connected to the first matching portion 22, and the locking rod 5 is also welded or connected to the first type rod 9 as a whole; optionally, the locking rod 5 is rotatably connected to the first matching portion 22, the first type rod 9 and the locking rod 5 are both round rods, and the first type rod 9 and the locking rod 5 are both rotatably and slidably arranged in the armrest assembly.

[0074] Please continue reading Figure 6 In order to ensure the sliding trajectory of the movable plate 10 and the first type of rod 9, the present embodiment provides a first guide rail 42 at the front of the mounting plate 4 to constrain the movement of the movable plate 10; similarly, the present embodiment also provides a second guide rail 43 at the front of the mounting plate 4 to constrain the movement of the first type of rod 9.

[0075] Please read further Figure 8 In this embodiment, the first type of rod 9 is specifically Z-shaped, and the middle part of the movable plate 10 is hollowed out, a spring 11 is arranged in the middle part, and a boss 44 is arranged on the mounting plate 4 (see Fig. 9 ) extends into the middle part; one end of the spring 11 is fixedly connected to the movable plate 10, and the other end is fixedly connected to the boss 44 belonging to the mounting plate 4, and is configured to elastically deform after the unlocking button 3 is pressed by the occupant, so that after the occupant removes the force applied to the unlocking button 3, the elastic member 122 can drive the movable plate 10 to reset.

[0076] Please refer back to Figure 6The armrest assembly in this embodiment also includes a transmission center 12 fixed to the mounting plate 4 by bolts, and a second type rod 13 slidably arranged on the mounting plate 4; in this embodiment, each transmission center 12 is connected to a first type rod 9 and a second type rod 13 at different positions thereof, and each second type rod 13 is connected to a locking rod 5, which is inserted into one end of the second type rod 13. The connection method of the locking rod 5 and the second type rod 13 can refer to the connection method of the locking rod 5 and the first type rod 9.

[0077] Please continue reading Figure 6 and Figure 8 The second type of rod 13 in this embodiment is Z-shaped and can slide on the mounting plate 4 along the front-rear direction with the locking rod 5; the structure of the second type of rod 13 is similar to that of the first type of rod 9, and the mounting plate 4 is also provided with a feature similar to the second guide rail 43 to constrain the movement of the second type of rod 13; the first type of rod 9 can be regarded as a second type of rod 13 that is extended by a section due to the need to cooperate with the unlocking button 3.

[0078] Please continue reading Figure 8 and Fig.10 The transmission center 12 in this embodiment exemplarily includes a lower shell 121, an elastic member 122 and two push-pull branches 123; wherein the lower shell 121 is provided with a matching groove 1211, the matching groove 1211 is used to accommodate at least part of the two push-pull branches 123 and at least part of the elastic member 122, the push-pull branches 123 can move along the matching groove 1211, and one end of each of the two push-pull branches 123 is connected to form a special-shaped force-applying portion 1231, and the force-applying portion 1231 can be slidably arranged In the matching groove 1211, a connecting portion 1232 is provided on the other end of each of the two push-pull branches 123; in addition, one end of the elastic member 122 contacts the inner wall of the matching groove 1211, and the other end contacts the force-applying portion 1231; the connecting portions 1232 of the two push-pull branches 123 are respectively fixedly connected to the first type of rod 9 and the second type of rod 13 (that is, one push-pull branch 123 is fixedly connected to the first type of rod 9, and the other push-pull branch 123 is fixedly connected to the second type of rod 13).

[0079] Based on the above, the connection between the aforementioned push-pull branch 123 and the first type of rod 9 is located at the end of the first type of rod 9 away from the first matching portion 22, and the connection between the other push-pull branch 123 and the second type of rod 13 is located at the end of the second type of rod 13 away from the end connected to the locking rod 5; the first type of rod 9 and the second type of rod 13 are respectively located on different sides of the force-applying portion 1231; the transmission center 12 is configured as follows: when the unlocking button 3 drives the first type of rod 9 to slide to unlock the armrest assembly, the elastic member 122 elastically deforms, and the first type of rod 9 can drive the push-pull branch 123 connected thereto to make adaptive movement, and drive the push-pull branch 123 connected to the second type of rod 13, so that the second type of rod 13 moves in the opposite direction of the first type of rod 9.

[0080] In other words, since the unlock button 3 can drive the first type rod 9 to slide forward and backward, and at the same time, the push-pull branch 123 connected to the first type rod 9 is linked to the push-pull branch 123 connected to the second type rod 13 through the force-applying portion 1231, so that there is a linkage relationship between the first type rod 9 and the second type rod 13, and the first type rod 9 and the second type rod 13 can move in opposite directions on the mounting plate 4. In this embodiment, when the unlock button 3 is pressed, the first type rod 9 and the second type rod 13 will both drive the locking rod 5 connected thereto to move in a direction close to the transmission center 12; at the same time, the elastic member 122 will be compressed by the force of the force-applying portion 1231 to make room for the push-pull branch 123 to move; then, once the occupant removes the external force acting on the unlock button 3, under the action of the spring 11 and the elastic member 122, the two push-pull branches 123, the first type rod 9 and the second type rod 13 will all be quickly reset.

[0081] Exemplarily, at least a portion of the connection portion 1232 of each of the two push-pull branches 123 protrudes out of the lower shell 121, and the connection portion 1232 of each of the two push-pull branches 123 is respectively engaged with the first type of rod 9 and the second type of rod 13; the connection portion 1232 of each of the two push-pull branches 123 is respectively engaged with the first type of rod 9 and the second type of rod 13 in a detachable manner. Specifically, when the transmission center 12 needs to be replaced, a tool is used to pry open or destroy the engagement between the connection portion 1232 of one push-pull branch 123 and the first type of rod 9, and then pry open the engagement between the connection portion 1232 of the other push-pull branch 123 and the second type of rod 13, so that the transmission center 12 can be removed from the mounting plate 4, and then a new transmission center 12 can be replaced.

[0082] Please continue reading Figure 8 and Fig.10 For example, the two push-pull branches 123 are connected to form a herringbone structure, and the first type of rod 9 and the second type of rod 13 are connected to two ends of the herringbone structure.

[0083] Exemplarily, the transmission center 12 further includes an upper shell 124 covering the lower shell 121 ; the upper shell 124 is welded to the lower shell 121 , which can ensure that the elastic member 122 and the two push-pull branches 123 are reliably constrained by the matching groove 1211 .

[0084] Please continue reading Fig.10 Exemplarily, the push-pull branch 123 includes a plurality of large diameter portions 1233 and small diameter portions 1234, the outer diameter of the large diameter portion 1233 is greater than the outer diameter of the small diameter portion 1234, and the large diameter portions 1233 and the small diameter portions 1234 are alternately arranged, and the alternating large diameter portions 1233 and small diameter portions 1234 are connected to form a chain structure located between the connecting portion 1232 and the force applying portion 1231.

[0085] Exemplarily, the push-pull branch 123 is a plastic product, such as polypropylene (PP). Of course, according to the actual needs of those skilled in the art, the push-pull branch 123 can be made of other flexible materials and can also be in various forms; and the large diameter portion 1233 and the small diameter portion 1234 can also be in various forms, such as block or plate.

[0086] Please refer back to Figure 5 and Figure 6 Since the present embodiment is provided with two unlocking buttons 3, two first-type rods 9 and two movable plates 10, the present embodiment is correspondingly provided with two second-type rods 13 and two transmission centers 12, as well as four locking rods 5; wherein one transmission center 12 is located in the left middle portion of the armrest assembly, and is respectively connected to one first-type rod 9 and one second-type rod 13, and the other transmission center 12 is located in the right middle portion of the armrest assembly, and is respectively connected to one first-type rod 9 and one second-type rod 13; two of the locking rods 5 are respectively connected to different first-type rods 9, and the remaining two of the locking rods 5 are respectively connected to different second-type rods 13.

[0087] Please continue reading Figure 5 and Figure 6 , and are further distinguished by their positions. The two first-type rods 9 in the armrest assembly are respectively the left front rod 92 and the right front rod 93, the two second-type rods 13 are respectively the right rear rod 131 and the left rear rod 132, and the four locking rods 5 are respectively the left front locking rod 51, the left rear locking rod 52, the right front locking rod 53 and the right rear locking rod 54. These parts have the following configurations:

[0088] The left front rod 92, the left rear rod 132, the right front rod 93, and the right rear rod 131 are respectively connected to the left front lock rod 51, the left rear lock rod 52, the right front lock rod 53, and the right rear lock rod 54; the transmission center 12 located on the left part of the armrest assembly is respectively connected to the left front rod 92 and the left rear rod 132, and the transmission center 12 located on the right part of the armrest assembly is respectively connected to the right front rod 93 and the right rear rod 131; the unlocking button 3 located on the left part of the armrest assembly can drive the left front lock rod 51 in and out of the first matching portion 22; the unlocking button 3 located on the right part of the armrest assembly can drive the right front lock rod 53 in and out of the first matching portion 22. In addition, in this embodiment, the second matching portion 23 is located between the right rear lock rod 54 and the left rear lock rod 52 (for convenience of illustration, the left rear lock rod 52 is filled in)

[0089] Thus, taking the armrest assembly being in a locked state and the armrest cover 1 turning a small angle from left to right as an example, the changes of the components in this process are as follows:

[0090] The unlocking button 3 located on the left part of the armrest assembly is pressed, the left front rod 92 moves backward, the left rear rod 132 moves forward, the left front locking rod 51 withdraws from the first matching portion 22, and the armrest assembly is unlocked; then, under the push of the coil spring 6, the armrest cover 1 rotates with the right front locking rod 53 as the rotation axis and is lifted up and flipped over.

[0091] Embodiment 2

[0092] like Fig.11 As shown (for ease of illustration, the left rear locking rod 52 is filled), this embodiment also provides a vehicle as generally described in the embodiment, and the vehicle is provided with an armrest assembly that is the same as the armrest assembly described in the first embodiment except for the following differences.

[0093] The armrest assembly of this embodiment is different from the armrest assembly of embodiment one in that the second matching portion 23 of this embodiment has two more protruding portions I (only one of which is shown in the figure) compared with the second matching portion 23 of embodiment one, and the two protruding portions I are equivalent to being respectively arranged at the left and right ends of the second matching portion 23 of embodiment one, and are extended portions of the second matching portion 23 of embodiment one after being extended to the left and right sides; based on this, when the armrest assembly is locked, the second matching portion 23 of this embodiment is rotatably connected to the left rear locking rod 52 at its left portion, and is rotatably connected to the right rear locking rod 54 at its right portion.

[0094] Exemplarily, the left portion of the protruding portion I is rotatably connected to the left rear locking rod 52 via a bearing member, and the right portion of the protruding portion I is rotatably connected to the right rear locking rod 54 via a bearing member.

[0095] So, like Fig.12 As shown (for ease of illustration, the left front locking rod 51 and the left rear locking rod 52 are filled), the shape of the force-bearing end cover 71 is also adaptively changed relative to the first embodiment to cover the protruding portion I and ensure that the left rear locking rod 52 can be extended in and out.

[0096] Based on the above arrangement, in this embodiment, the unlocking button 3 located on the left side of the armrest assembly can drive the left rear locking rod 52 in and out of the second matching portion 23, and the unlocking button 3 located on the right side of the armrest assembly can drive the right rear locking rod 54 in and out of the second matching portion 23.

[0097] Based on the above, when the unlocking button 3 located at the left front part of the armrest assembly is pressed and the left part of the armrest assembly is unlocked, the armrest cover 1, the mounting plate 4 and the cover body 7 will turn over with the right front locking rod 53 and the right rear locking rod 54 as the rotation axis under the push of the coil spring 6; similarly, when the unlocking button 3 located at the right front part of the armrest assembly is pressed and the right part of the armrest assembly is unlocked, the armrest cover 1, the mounting plate 4 and the cover body 7 will turn over with the left rear locking rod 52 and the left front locking rod 51 as the rotation axis under the push of the coil spring 6.

[0098] It should be noted that, although both Embodiment 1 and Embodiment 2 mention an armrest assembly that can be opened in both directions, for the present invention, the coil spring 6, transmission center 12 and other settings related to the two (such as the first type of rod 9, the second type of rod 13, the unlocking button 3, the movable plate 10) of the present invention are obviously not only applicable to the armrest assembly that can be opened in both directions; for example, if an armrest assembly only needs to be flipped from left to right or from right to left, then corresponding deletions and modifications are made on the basis of Embodiment 1 and Embodiment 2 of the present invention, so that the left or right part of the armrest assembly is only provided with a simple rotation axis.

[0099] In summary, by using the coil spring 6 to provide a thrust force for the armrest cover 1 , the present invention can provide an armrest assembly with low installation and adjustment difficulty.

[0100] Furthermore, compared with the armrest assembly proposed in the background technology, the armrest assembly provided by the present invention has the advantage of being lightweight; specifically, the provision of a torsion spring will inevitably affect the lightweight design of the armrest assembly, and the torsion springs in the related technology all need to be entirely mounted on a rod-shaped component, a portion of the physical length of the rod-shaped component exists to cooperate with the torsion spring. Obviously, this will cause the rod-shaped component and the armrest assembly to have a certain length, which will indirectly increase the floor space, weight, consumables and production costs of the armrest assembly; in comparison, there is no need to set such a rod-shaped component in the armrest assembly of the present invention.

[0101] In addition, in the related art, a linkage rod respectively connected to the two torsion springs respectively arranged on the left and right parts of the armrest assembly is often provided. Obviously, this further increases the complexity, weight, consumables and production costs of the armrest assembly. In comparison, there is no need to provide such a linkage rod in the armrest assembly in the present invention.

[0102] Furthermore, in the related art, since the armrest cover is provided with a pushing force by a torsion spring, at least one of the two torsion springs of the armrest assembly in the related art is often configured to be exposed after the armrest cover 1 is opened, and such exposure easily affects the occupant's perception of the armrest assembly; in comparison, in the armrest assembly of the present invention, the coil spring 6 is hidden under the buffer block 8 and will not be exposed within the occupant's visual range.

[0103] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
