Description

Technical Field

[0001] The present invention relates to the technical field of seat armrests on vehicles, and more specifically, to an automotive armrest mounting bracket assembly. Background Art

[0002] The mounting bracket assembly of the seat armrest of a motor vehicle is an important component in the vehicle interior, which is directly related to the comfort and safety of passengers. With the development of the automotive industry, the requirements for the ergonomic design, safety performance, and user experience of in-vehicle facilities are also constantly increasing.

[0003] Existing MPV models usually face a challenge in seat layout. To meet the large seating demand, it is necessary to optimize the design of the middle row and rear row seats. However, there is a significant problem in the current design: to facilitate the entry and exit of rear passengers, the middle row seats are often set to have only two seats, leaving a middle aisle. This arrangement, while facilitating the entry and exit of rear passengers, sacrifices a potential seating position in the middle row. Conversely, if an additional seat is added in the middle row, it will impede the convenient entry and exit of rear passengers. Therefore, an ideal design solution should be to ensure that rear passengers can enter and exit easily, while also having the function of providing an additional seat in the middle row when needed. This can not only improve the space utilization rate of the vehicle but also enhance the overall riding experience of passengers.

[0004] Based on this, the present invention discloses an automotive armrest mounting bracket assembly. Summary of the Invention

[0005] To solve the challenge in the seat design of existing MPV models in the background art, which is to balance the number of middle row seats and the convenience of rear passenger entry and exit, and to find a solution that can not only facilitate the seating of rear passengers but also add an additional seat in the middle row when necessary, the present invention provides an automotive armrest mounting bracket assembly, which includes two symmetrically arranged mounting brackets. A base is provided on the mounting bracket, and a backrest is provided on the base. Installation grooves are formed on one side of the two backrests facing each other, and an installation box is fixedly provided in the installation groove. In this technical solution, in order to make the temporary seat not only have a single function, the temporary seat needs to be movable up and down, so a rotatable support structure is required as a basis. As a further improvement of the technical solution, an installation component is provided at the central position of the installation box; wherein, the installation component includes an installation sleeve fixed in the installation box, first limiting grooves are symmetrically formed on both sides of the installation sleeve, a second limiting groove with an annular structure is further formed on the installation sleeve, both ends of the second limiting groove are communicated with the ends of the first limiting grooves on both sides of the installation sleeve respectively, elastic limiting blocks are arranged in the first limiting grooves, a rotating rod is arranged in the installation sleeve, and the rotating rod is slidably connected with the first limiting groove and the second limiting groove through the elastic limiting blocks; a tension spring is arranged in the installation sleeve, and the rotating rod is connected with the installation sleeve through the tension spring.

[0006] On this basis, in order to cooperate with the flipping between the temporary seat and the rotating rod, a basic support is needed. As a further improvement of the technical solution, a rotating component is arranged on the installation component, a connecting component is arranged at one end of the rotating component away from the installation component, and an armrest body is rotatably arranged on the connecting component.

[0007] In another technical solution, in order to realize the function of converting the armrest body into a lumbar pad, the armrest body needs to be lifted from one side of the base to the junction of the base and the chair back. Secondly, when the armrest body forms a temporary seat, if a passenger wants to take a seat, the armrest body needs to be retracted to provide space for the passenger to enter the back row. As a further improvement of the technical solution, the rotating component includes a rotating plate, one end of the rotating plate is fixedly connected with the rotating rod, a third support rod is fixedly connected to the other end of the rotating plate on the same side as the rotating rod, and a first sliding groove is formed on the side of the rotating plate away from the rotating rod; the connecting component includes a sliding rod slidably connected in the first sliding groove, a connecting rod is rotatably connected to the side of the sliding rod away from the rotating plate, and one end of the connecting rod away from the sliding rod is rotatably connected to one end of the armrest body. In order to prevent the armrest body from rotating in the reverse direction around the connecting rod and getting out of position, a limiting block for preventing the armrest body from flipping and getting out of position is fixedly arranged at the rotating connection of the armrest body and the connecting rod.

[0008] Since the temporary seat bears the weight of the passengers, a support structure needs to be added, that is, supports need to be added directly below the armrest body and at the end of the armrest body away from the connecting rod. As a further improvement of the technical solution, support components are arranged on the opposite sides of the two bases. Among them, the support component includes a support plate fixed on the mounting frame, a second sliding groove is formed on the support plate, and a number of third limiting grooves are formed in the second sliding groove; a clamping groove is formed on the side of the armrest body close to the base, the bottom of the clamping groove is provided with a through port, and a first support rod is fixedly arranged on one side of the base.

[0009] In the third solution, when the state of the armrest body needs to be converted to the armrest state, that is, in addition to providing the functions of a temporary seat and a lumbar cushion, the armrest body can also be converted into an armrest to provide convenience for passengers; As a further improvement of this technical solution, a receiving groove is opened at the bottom of the armrest body, and a second support rod is rotatably arranged in the receiving groove; when the armrest body forms an armrest, different third limiting grooves in the second support rod and the second sliding groove are engaged to form armrest bodies with different inclination angles, meeting the needs of passengers for adjusting the armrest angle. At the same time, the second support rod cooperates with the upper and lower ends of the rotating plate to form an overall support for the armrest body.

[0010] Compared with the prior art, the beneficial effects of the present invention are: 1. In this automotive armrest mounting bracket assembly, a hidden seat and space conversion is realized. Through the cooperation of the rotating rod and the elastic limiting block arranged in the mounting box, during operation, the rotating rod is pulled out along the first limiting groove and then rotated 180°, and is reset under the action of the tension spring, realizing the switching of the armrest body between the seat and the hidden state. This structure enables the gap between the two middle-row seats to be quickly expanded into a temporary seat or stored as a hidden space, which not only meets the need for temporarily adding seats but also leaves a passage for the rear-row passengers to enter and exit, solving the contradiction between the number of middle-row seats and the convenience of passage.

[0011] 2. In this automotive armrest mounting bracket assembly, multi-state support stability is realized. The matching design of the support sleeve and the third support rod, when the armrest body is expanded into a temporary seat or a lumbar cushion, the third support rod is engaged with the bottom / top support sleeve, combined with the double-end limiting of the rotating rod, to form a double support point. Together with the fixing of the support plate and the first support rod to the card slot, the load-bearing stability of the temporary seat is significantly improved, avoiding the structural fatigue of single-point support.

[0012] 3. In this automotive armrest mounting bracket assembly, flexible switching of multi-functional forms is realized. Through the sliding of the sliding rod in the first sliding groove and the rotation of the connecting rod, the armrest body can be horizontally lifted along the junction of the base and the chair and rotated to the lumbar cushion, or the whole can be flipped to the armrest through the rotating plate. Combined with the engagement of the second support rod and the third limiting groove, multi-level adjustment of the armrest angle is realized, meeting the personalized needs of passengers for lumbar cushion support, armrest height, and inclination angle.

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] Existing MPV models face challenges in seat design to balance the number of middle-row seats and the convenience of rear-row passengers getting in and out. A solution is needed that can facilitate the entry of rear-row passengers and add an extra seat in the middle row when necessary.

[0031] For this purpose, the present invention provides an armrest mounting bracket assembly for an automobile. Refer to Figure 1 - Figure 2 As shown, it includes two symmetrically arranged mounting brackets 1, that is, the two seats in the middle row. There is a gap between the two seats. A base 2 is provided on the mounting bracket 1, and a backrest 3 is provided on the base 2; In order to be able to design a temporary seat in the gap between the two middle-row seats, and at the same time this seat not only serves as a seat, but also provides some space for rear-row passengers to enter the seat, so one side of the backrest 3 needs to be set as a hidden type; specifically, mounting grooves 4 are opened on the opposite sides of the two backrests 3, and a mounting box 5 is fixedly provided in the mounting grooves 4.

[0032] Refer to Figure 3 - Figure 5 As shown, in order to enable the temporary seat to have more than just a single function, the temporary seat needs to be able to move up and down, so a rotatable support structure is required as a basis. Therefore, a mounting component 6 is provided at the center of the mounting box 5; among them, the mounting component 6 includes a mounting sleeve 61 fixedly provided in the mounting box 5. First limiting grooves 62 are symmetrically opened on both sides of the mounting sleeve 61. A second limiting groove 63 in a ring structure is also opened on the mounting sleeve 61. The two ends of the second limiting groove 63 are respectively communicated with the ends of the first limiting grooves 62 on both sides of the mounting sleeve 61. Elastic limiting blocks 66 are provided in the first limiting grooves 62. A rotating rod 65 is provided in the mounting sleeve 61. The rotating rod 65 is slidably connected to the first limiting grooves 62 and the second limiting groove 63 through the elastic limiting blocks 66; a tension spring 64 is provided in the mounting sleeve 61. The rotating rod 65 is connected to the mounting sleeve 61 through the tension spring 64.

[0033] During operation, the rotating rod 65 is first located in the first limiting groove 62 on one side of the mounting sleeve 61. Then, when it is necessary to change the state of the temporary seat, the rotating rod 65 is pulled out, so that the rotating rod 65 slides in the first limiting groove 62 through the elastic limiting block 66 to the second limiting groove 63, and then rotates until the elastic limiting block 66 slides into the first limiting groove 62 on the other side of the mounting sleeve 61. After that, under the action of the tension spring 64 and with an external force, it is reset to the top of the first limiting groove 62 on the other side of the mounting sleeve 61, completing a 180-degree flip of the rotating rod 65 and realizing the state change of the temporary seat. The front end of the elastic limiting block 66 is an elastic part, so that when the elastic limiting block 66 transitions from the second limiting groove 63 to the first limiting groove 62, there will be an elastic feedback to inform the user that the specified position has been reached, and then the user can let go and wait for the tension spring 64 to pull the rotating rod 65 back into the first limiting groove 62.

[0034] Further, referring to Figure 3 、 Figure 6 - Figure 7 As shown, in order to cooperate with the flip between the temporary seat and the rotating rod 65, a basic support is required. Therefore, a rotating component 8 is provided on the mounting component 6. One end of the rotating component 8 away from the mounting component 6 is provided with a connecting component 9, and an armrest body 10 is rotatably arranged on the connecting component 9. The armrest body 10 is the temporary seat, and a lumbar support groove 11 is opened on the armrest body 10. The lumbar support groove 11 and the waist form a support structure, and the two lumbar support grooves 11 form a concave structure, which forms a support structure with the buttocks. It can be seen from Figure 1 and Figure 8 that when the armrest body 10 rotates horizontally to the junction of the base 2 and the chair back 3, a lumbar cushion can be formed in cooperation with the lumbar support groove 11. When the two armrest bodies 10 are combined, that is, when the armrest bodies 10 are located on the same side of the base 2, the two armrest bodies 10 form a temporary seat.

[0035] Among them, the rotating component 8 includes a rotating plate 81. One end of the rotating plate 81 is fixedly connected to the rotating rod 65, and a third support rod 83 is fixedly connected to the other end of the rotating plate 81 on the same side as the rotating rod 65. A first sliding groove 82 is opened on the side of the rotating plate 81 away from the rotating rod 65; the connecting component 9 includes a sliding rod 91 slidably connected in the first sliding groove 82. One side of the sliding rod 91 away from the rotating plate 81 is rotatably connected to a connecting rod 92, and one end of the connecting rod 92 away from the sliding rod 91 is rotatably connected to one end of the armrest body 10. In order to prevent the armrest body 10 from rotating in the reverse direction around the connecting rod 92 and getting out of position, a limiting block 18 for preventing the armrest body 10 from flipping and getting out of position is fixedly provided at the rotating connection between the armrest body 10 and the connecting rod 92; During operation, the rotating plate 81 rotates around the center of the rotating rod 65, driving the rotation of the armrest body 10 through the connecting rod 92. When the armrest body 10 is at both ends of the trajectory where the rotating plate 81 flips 180 degrees, that is, directly above or below the rotating rod 65, a basic support is also required at the end of the rotating plate 81. Therefore, support sleeves 7 are symmetrically and fixedly installed at the upper and lower ends inside the installation box 5, and the inner diameter of the support sleeve 7 is adapted to the outer diameter of the third support rod 83; In addition, the distance from the center of the support sleeve 7 to the center of the rotating rod 65 is equal to the distance from the third support rod 83 to the center of the rotating rod 65, and the length of the first limiting groove 62 is adapted to the length of the third support rod 83; the arc length of the second limiting groove 63 satisfies the 180-degree rotation of the rotating plate 81. That is to say, when the elastic limiting block 66 is at the top end of the first limiting groove 62 on one side of the installation sleeve 61, the rotating plate 81 is vertically downward, and the third support rod 83 is engaged with the support sleeve 7 at the bottom of the installation box 5. In this way, through the upper and lower ends of the rotating plate 81, that is, the double support of the rotating rod 65 and the third support rod 83, a basic support at the rotating position is formed, providing stable support for subsequent passengers to take their seats or when the armrest ensures the rotating position; similarly, when the elastic limiting block 66 is pulled out by the rotating rod 65 to the position of the second limiting groove 63, the third support rod 83 disengages from the support sleeve 7 at the bottom of the installation box 5. Then, after the rotating rod 65 drives the rotating plate 81 to rotate 180 degrees and then releases the hand, the third support rod 83 at the bottom of the rotating plate 81 flips 180 degrees and is engaged with the support sleeve 7 at the top of the installation box 5.

[0036] During the rotation of the rotating plate 81, in order to ensure that the connecting rod 92 can finally maintain an adjustable angle and ultimately meet the requirements for realizing the armrest, temporary seat, and lumbar pad, the connecting rod 92 is rotatably connected to the sliding rod 91; In addition, in order to realize the function of converting the armrest body 10 into a lumbar pad, the armrest body 10 needs to be raised from one side of the base 2 to the junction of the base 2 and the chair 3. Secondly, when the armrest body 10 forms a temporary seat, if a passenger wants to take a seat, the armrest body 10 needs to be retracted to provide space for the passenger to enter the back row. Therefore, the armrest body 10 can slide up and down in the first sliding groove 82 in cooperation with the connecting rod 92 and the sliding rod 91. In this way, when needed, the armrest body 10 can be directly lifted to the horizontal position at the junction of the base 2 and the chair 3, and then the armrest body 10 is rotated to be located at the junction of the base 2 and the chair 3 to form a lumbar pad, that is Figure 8 as shown, so that both a lumbar pad can be formed and the position of the armrest body 10 can be converted to provide space for passengers to enter the back row.

[0037] Furthermore, referring to Figure 2 、 Figure 3 、 Figure 9 and Figure 11As shown in the figure, when the two armrest bodies 10 jointly form a temporary seat, in addition to the support of the third support rod 83 and the rotating rod 65, since the temporary seat bears the weight of the passengers, it is necessary to add a support structure, that is, it is necessary to add supports directly below the armrest bodies 10 and at the ends of the armrest bodies 10 away from the connecting rod 92; therefore, support components 16 are provided on the opposite sides of the two bases 2. Among them, the support component 16 includes a support plate 161 fixed on the mounting frame 1. A second chute 162 is opened on the support plate 161, and a number of third limiting grooves 163 are opened in the second chute 162; in this way, when the armrest body 10 forms a temporary seat on one side of the base 2, the armrest body 10 can fit against the top of the support plate 161 to form a flat support. Secondly, a card slot 12 is opened on the side of the armrest body 10 adjacent to the base 2, and the bottom of the card slot 12 is provided with a through opening. A first support rod 13 is fixed on one side of the base 2. When the armrest body 10 is in the first state, the first support rod 13 is engaged in the card slot 12 to form a support structure; in this way, when the armrest body 10 needs to be lifted, the first support rod 13 can be disengaged through the through opening at the bottom of the card slot 12, and when the armrest body 10 is located on the top of the support plate 161, the first support rod 13 can cooperate with the card slot 12 to further support the armrest body 10.

[0038] In addition, as Figure 12 - Figure 15 shown, when the state of the armrest body 10 needs to be converted into an armrest state, that is, when the third support rod 83 rotates from the support sleeve 7 at the bottom of the installation box 5 to the support sleeve 7 at the top of the installation box 5, the rotating plate 81 drives the connecting rod 92 to flip 180 degrees, realizing the raising of the height of the armrest body 10 so that it reaches a position above one side of the base 2, that is, in addition to providing the functions of a temporary seat and a lumbar cushion, the armrest body 10 can also be converted into an armrest to provide convenience for passengers; therefore, a receiving groove 14 is opened at the bottom of the armrest body 10, and a second support rod 15 is rotatably arranged in the receiving groove 14. That is to say, the armrest body 10 has the following three states: The first state: the sliding rod 91 is located at the bottom of the first chute 82, the armrest body 10 is located on the support plate 161, the first support rod 13 is engaged in the card slot 12, and the two armrest bodies 10 form a temporary seat; The second state: the sliding rod 91 is located at the top of the first chute 82, the armrest body 10 is raised to the horizontal position at the junction of the base 2 and the chair 3, and then the armrest body 10 is rotated to form a lumbar cushion at the junction of the base 2 and the chair 3; The third state: the sliding rod 91 is located at the bottom of the first chute 82, but the rotating plate 81 rotates 180 degrees, so that the third support rod 83 is engaged with the support sleeve 7 at the top of the installation box 5, and the second support rod 15 abuts against the third limiting groove 163 in the second chute 162. At this time, the armrest body 10 is located above one side of the base 2 to form an armrest.

[0039] When the armrest body 10 forms an armrest, different inclined angles of the armrest body 10 are formed by the engagement of the second support rod 15 and different third limiting grooves 163 in the second chute 162, meeting the needs of passengers for adjusting the armrest angle. At the same time, the second support rod 15 cooperates with the upper and lower ends of the rotating plate 81 to form an overall support for the armrest body 10.

[0040] In addition, as Figure 9 , Figure 14 - Figure 15 In order to enable the retraction and extension of the second support rod 15 to meet the user's needs when converting the state of the armrest body 10, it is necessary to limit the second support rod 15. That is, a control assembly 17 for controlling the retraction and extension of the second support rod 15 is provided on the side of the armrest body 10 close to the base 2. Among them, the control assembly 17 includes an adjustment groove 171 opened at a position in the armrest body 10 close to the accommodation groove 14. An installation rod 173 is fixedly provided in the adjustment groove 171. An adjustment rod 172 is rotatably connected to the installation rod 173. A return spring 174 is also provided in the adjustment groove 171. The adjustment rod 172 is connected to the inner wall of the adjustment groove 171 through the return spring 174; It should be added that the adjustment rod 172 has an S-shaped structure. In the initial state, one end of the adjustment rod 172 has a wedge-shaped structure and is in contact with the bottom of the second support rod 15, and the other end of the adjustment rod 172 extends outside the armrest body 10 to form a pressing part.

[0041] During operation, the seated passenger presses the pressing part of the adjustment rod 172 exposed outside, causing the adjustment rod 172 to rotate around the installation rod 173, thereby releasing the limit of the bottom of the adjustment rod 172 on the second support rod 15. The second support rod 15 rotates out under the action of gravity, and then the position of the second support rod 15 in the second chute 162 can be adjusted manually. After the hand releases the pressing of the pressing part, under the action of the return spring 174, the adjustment rod 172 resets. When it is necessary to retract the second support rod 15, after the second support rod 15 is retracted into the accommodation groove 14, continue to press the pressing part so that the second support rod 15 is located above the bottom of the adjustment rod 172, or directly press the second support rod 15 to form an extrusion on the bottom of the adjustment rod 172, which can all realize the re-limiting of the bottom of the adjustment rod 172 on the second support rod 15.

[0042] Working principle: In the initial state, the two armrest bodies 10 form a temporary seat. The third support rod 83 is located in the support sleeve 7 at the bottom of the installation box 5. The armrest bodies 10 are located on top of the support plate 161. The first support rod 13 is engaged in the card slot 12. When it is necessary to convert the armrest body 10 into a lumbar cushion or when a passenger needs to take a seat in the back row and space is required in the middle row, then the armrest body 10 needs to be lifted so that it disengages from the first support rod 13 and the support plate 161. The armrest body 10 slides along the first sliding groove 82 through the sliding rod 91 to the top. At this time, the armrest body 10 is at the horizontal line position at the junction of the base 2 and the backrest 3. Then the armrest body 10 is rotated to the junction of the base 2 and the backrest 3 to form a lumbar cushion. If the armrest body 10 is to be formed into an armrest, the rotating plate 81 drives the rotating rod 65 to extract it, so that the elastic limiting block 66 is extracted along the first limiting groove 62 to the position of the second limiting groove 63. At this time, the third support rod 83 disengages from the support sleeve 7. After that, the rotating plate 81 can be rotated as a whole, so that the third support rod 83 at the bottom of the rotating plate 81 rotates to the position of the support sleeve 7 at the top of the installation box 5. Then the rotating rod 65 is reset so that the third support rod 83 is engaged with the support sleeve 7 at the top. At this time, the armrest body 10 is lifted to a position suitable for an armrest. Then the connecting rod 92, the rotating rod 65 and the third support rod 83 provide basic support. After that, the pressing part of the adjusting rod 172 is pressed to release the second support rod 15. Then the engagement with the third limiting groove 163 is adjusted through the second support rod 15. Then the connecting rod 92 can be rotated so that the armrest body 10 is at different angles, and finally the support of the armrest is provided.

[0043] In summary, through the elastic limiting and rotating structure of the installation component 6, the double support sleeve design of the rotating component 8, the sliding rail linkage of the connecting component 9, and the multi-point load-bearing optimization of the support component 16, this solution realizes the seamless switching among the four functional scenarios of temporary seat addition, passenger passage, lumbar cushion support and armrest adjustment for the middle row seats. Furthermore, it effectively solves the challenge faced by existing MPV models in seat design, which is to balance the number of middle row seats and the convenience of rear row passengers entering and exiting, and to seek a solution that can not only facilitate the entry of rear row passengers but also add a seat in the middle row when necessary.
