Description

Technical Field

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

[0002] The mounting bracket assembly of an automobile vehicle seat armrest is an important component in the vehicle interior, which is directly related to the comfort and safety of passengers. With the development of the automobile 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. In order 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: in order to facilitate the entry and exit of rear passengers, the middle row seats are often arranged with only two seats, leaving a middle aisle. This arrangement facilitates the entry and exit of rear passengers, but sacrifices a potential position in the middle row seats. On the contrary, if an additional seat is added in the middle row, it will hinder the convenient entry and exit of rear passengers. Therefore, an ideal design solution should be able 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 automobile 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 passengers' entry and exit, and to seek a solution that can not only facilitate the entry of rear passengers but also add an additional seat in the middle row when necessary, the present invention provides an automobile 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. Mounting grooves are formed on the opposite sides of the two backrests, and a mounting box is fixedly provided in the mounting groove.

[0006] In this technical solution, in order to make the temporary seat not only have a single function, it is necessary to make the temporary seat movable up and down, so a rotatable support structure is required as a basis.

[0007] 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, and a second limiting groove with an annular structure is also formed on the installation sleeve. The two ends of the second limiting groove are respectively communicated with the ends of the first limiting grooves on both sides of the installation sleeve. Elastic limiting blocks are arranged in the first limiting grooves, and a rotating rod is arranged in the installation sleeve. The rotating rod is slidably connected to 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 to the installation sleeve through the tension spring.

[0008] On this basis, in order to cooperate with the flipping between the temporary seat and the rotating rod, a basic support is required.

[0009] As a further improvement of the technical solution, a rotating component is arranged on the installation component. One end of the rotating component away from the installation component is provided with a connecting component, and an armrest body is rotatably arranged on the connecting component.

[0010] 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 raised 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.

[0011] As a further improvement of the technical solution, the rotating component includes a rotating plate. One end of the rotating plate is fixedly connected to the rotating rod, and a third support rod is fixedly connected to the other end of the rotating plate on the same side as the rotating rod. 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. One side of the sliding rod away from the rotating plate is rotatably connected to a connecting rod, 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.

[0012] 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.

[0013] 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, and the bottom of the clamping groove is provided with a through opening. A first support rod is fixedly arranged on one side of the base.

[0014] In the third solution, when the state of the armrest body needs to be converted into the armrest state, that is, in addition to providing the functions of a temporary seat and a lumbar pad, the armrest body can also be converted into an armrest to provide convenience for passengers;

[0015] 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 the armrest body at 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.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 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 temporary additional seats but also leaves a passage for the rear passengers to enter and exit, solving the contradiction between the number of middle-row seats and the convenience of passage.

[0018] 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 pad, the third support rod is engaged with the bottom / top support sleeve, combined with the double-end limit of the rotating rod, to form a double support point. Cooperating 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.

[0019] 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 seat back and rotated to the lumbar pad, or the whole can be flipped to the armrest through the rotating plate. Combining 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 pad support, armrest height, and inclination angle.

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] Existing MPV models face the challenge of balancing the number of middle-row seats and the convenience of rear-row passengers getting in and out in seat design. It is necessary to find a solution that can facilitate the rear-row passengers to sit down and add a seat to the middle row when necessary.

[0044] To this end, the present invention provides a vehicle armrest mounting bracket assembly, see Figures 1 - 2 As shown, it comprises two symmetrically arranged mounting frames 1, namely two seats in the middle row, with a gap between the two seats, a base 2 is arranged on the mounting frame 1, and a backrest 3 is arranged on the base 2;

[0045] In order 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 needs to provide a certain space for the rear passengers to sit down, it is necessary to set one side of the backrest 3 to be hidden; specifically, an installation groove 4 is opened on the opposite side of the two backrests 3, and an installation box 5 is fixed in the installation groove 4.

[0046] Reference Figures 3 - 5As shown in the figure, in order to make the temporary seat have more than a single function, the temporary seat needs to be able to move up and down. Therefore, a rotatable support structure is required as the basis, and an installation component 6 is provided at the center of the installation box 5. Among them, the installation component 6 includes an installation sleeve 61 fixed in the installation box 5. First limiting grooves 62 are symmetrically formed on both sides of the installation sleeve 61. An annular second limiting groove 63 is also formed on the installation 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 installation sleeve 61. Elastic limiting blocks 66 are arranged in the first limiting grooves 62. A rotating rod 65 is arranged in the installation 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 arranged in the installation sleeve 61. The rotating rod 65 is connected to the installation sleeve 61 through the tension spring 64.

[0047] During operation, the rotating rod 65 is first located in the first limiting groove 62 on one side of the installation sleeve 61. Then, when the state of the temporary seat needs to be changed, the rotating rod 65 is pulled out, so that the rotating rod 65 slides in the first limiting groove 62 to the second limiting groove 63 through the elastic limiting block 66, and then rotates until the elastic limiting block 66 slides into the first limiting groove 62 on the other side of the installation sleeve 61. After that, under the action of the tension spring 64 and with the cooperation of an external force, it is reset to the top of the first limiting groove 62 on the other side of the installation 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 member, 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.

[0048] Furthermore, referring to Figure 3 、 Figures 6 - 7 As shown in the figure, 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 installation component 6. A connecting component 9 is arranged at the end of the rotating component 8 away from the installation component 6. An armrest body 10 is rotatably arranged on the connecting component 9. Among them, the armrest body 10 is the temporary seat. A lumbar support groove 11 is formed on the armrest body 10. The lumbar support groove 11 and the waist form a support structure. The two lumbar support grooves 11 form a concave structure and form a support structure with the buttocks. From Figure 1 and Figure 8 it can be seen 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.

[0049] 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. The other end of the rotating plate 81 on the same side as the rotating rod 65 is fixedly connected with a third support rod 83. A first chute 82 is formed 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 chute 82. One side of the sliding rod 91 away from the rotating plate 81 is rotatably connected with a connecting rod 92. 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 limit block 18 for preventing the armrest body 10 from flipping and getting out of position is fixedly provided at the rotational connection between the armrest body 10 and the connecting rod 92;

[0050] 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 provided at the upper and lower ends inside the installation box 5. The inner diameter of the support sleeve 7 is adapted to the outer diameter of the third support rod 83;

[0051] 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 center of the third support rod 83 to the center of the rotating rod 65. 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 for the armrest to ensure 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 is released, 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.

[0052] 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;

[0053] In addition, in order to convert the armrest body 10 into a lumbar cushion, the armrest body 10 needs to be lifted from one side of the base 2 to the junction of the base 2 and the chair 3. Secondly, when a temporary seat is formed on the armrest body 10, if a passenger wants to sit down, 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 chute 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 cushion, that is Figure 8 as shown, so that not only a lumbar cushion can be formed, but also the position of the armrest body 10 can be converted to provide space for passengers to enter the back row.

[0054] Furthermore, referring to Figure 2 , Figure 3 , Figure 9 and Figure 11 as shown, when 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, a support structure needs to be added, that is, supports need to be added directly below the armrest body 10 and at one end of the armrest body 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 provided in the support plate 161, and a number of third limiting grooves 163 are provided 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 on the top of the support plate 161 to form a flat support. Secondly, a card slot 12 is provided on the side of the armrest body 10 close to the base 2, and the bottom of the card slot 12 is provided as a through port. 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 port 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.

[0055] In addition, as Figures 12 - 15As shown, when the state of the armrest body 10 needs to be converted into the armrest state, that is, when the third support rod 83 rotates from the support sleeve 7 at the bottom of the installation box 5 into 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 to a position above one side of the base 2. That is, in addition to providing a temporary seat and 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:

[0056] The first state: the sliding rod 91 is located at the bottom of the first sliding groove 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.

[0057] The second state: the sliding rod 91 is located at the top of the first sliding groove 82, the armrest body 10 rises 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.

[0058] The third state: the sliding rod 91 is located at the bottom of the first sliding groove 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 limit groove 163 in the second sliding groove 162. At this time, the armrest body 10 is located above one side of the base 2 to form an armrest.

[0059] 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 limit grooves 163 in the second sliding groove 162 to meet 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.

[0060] In addition, as Figure 9 、 Figures 14 - 15 In order to enable the retraction and extension of the second support rod 15 to meet the needs of users when converting the state of the armrest body 10, it is necessary to limit the second support rod 15. That is, a control component 17 for controlling the retraction and extension of the second support rod 15 is provided on one side of the armrest body 10 close to the base 2. Among them, the control component 17 includes an adjustment groove 171 opened at a position in the armrest body 10 close to the receiving groove 14. An installation rod 173 is fixedly arranged in the adjustment groove 171. An adjustment rod 172 is rotatably connected to the installation rod 173. A return spring 174 is also arranged 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;

[0061] It should be added that the adjusting rod 172 is in an S-shaped structure. In the initial state, one end of the adjusting rod 172 is in a wedge-shaped structure and fits against the bottom of the second support rod 15, and the other end of the adjusting rod 172 extends outside the armrest body 10 to form a pressing part.

[0062] During operation, the seated passenger presses the pressing part of the adjusting rod 172 exposed outside, causing the adjusting rod 172 to rotate around the mounting rod 173, thereby releasing the limit of the bottom of the adjusting 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 sliding groove 162 can be adjusted manually. After the hand releases the pressing of the pressing part, under the action of the return spring 174, the adjusting rod 172 resets. When the second support rod 15 needs to be retracted, after the second support rod 15 is retracted into the receiving groove 14, continue to press the pressing part so that the second support rod 15 is located above the bottom of the adjusting rod 172, or directly press the second support rod 15 to form an extrusion on the bottom of the adjusting rod 172, which can all achieve the re-limitation of the bottom of the adjusting rod 172 on the second support rod 15.

[0063] Working principle:

[0064] 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 body 10 is located on the top of the support plate 161, and 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 pad or when a passenger needs to sit in the back row and the middle row needs to provide space, then the armrest body 10 needs to be lifted to disengage it from the first support rod 13 and the support plate 161. The armrest body 10 slides along the first sliding groove 82 to the top through the sliding rod 91. At this time, the armrest body 10 is located at the horizontal line position at the junction of the base 2 and the chair 3, and then the armrest body 10 is rotated to the junction of the base 2 and the chair 3 to form a lumbar pad. If the armrest body 10 is to form 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, and then the entire rotating plate 81 can be rotated 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, and 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, and then the connecting rod 92, the rotating rod 65 and the third support rod 83 provide basic support. Then, press the pressing part of the adjusting rod 172 so that the second support rod 15 is released, and then adjust the engagement with the third limiting groove 163 through the second support rod 15, and 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.

[0065] In summary, through the elastic limit and rotation structure of the installation component 6, the double-support sleeve design of the rotation component 8, the slide rail linkage of the connection component 9, and the multi-point load-bearing optimization of the support component 16, this solution realizes the seamless switching of the middle-row seat among four functional scenarios: temporary seat addition, passenger passage, lumbar support, and armrest adjustment. 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. There is a need to find a solution that can not only facilitate the rear-row passengers to take their seats but also add a seat to the middle row when necessary.
