Description

Technical Field

[0001] The invention relates to the technical field of automobile seats, and in particular to a multifunctional armrest automobile seat structure. Background Art

[0002] As car use becomes more prevalent, users are putting forward more and more requirements for cars. As the car seat with the largest direct contact area with passengers, it is one of the most frequently used products in the vehicle. Users are paying more and more attention to the structural rationality, convenience of use and riding comfort of car seats, and their requirements are also increasing accordingly.

[0003] The seat assemblies provided in current cars mainly consist of the front driver and passenger seats plus a center armrest, and the middle and rear rows are independent seats or 4:6 seats. The number of seats in the car remains constant; especially for family cars, the front row has two seats, the driver and passenger seats, and the rear row is usually 4:6 seats. When special circumstances or emergencies occur and the car needs to carry one more person, the number of seats in the car cannot meet the demand; in addition, the application scenarios of the seats in the car are single. For example, when the rear passengers need a desk for work or entertainment, the current seat assemblies cannot meet their requirements. Summary of the invention

[0004] In view of the problems existing in the above-mentioned prior art, the present invention aims to provide a multifunctional armrest car seat structure to solve the problem of the single usage scenario of the existing seat assembly, thereby improving the convenience of use and riding comfort of the seat assembly.

[0005] In order to achieve the above-mentioned purpose, the present invention proposes a multifunctional armrest car seat structure, comprising a driver's seat, a passenger seat and a rear seat, wherein a middle armrest is arranged between the driver's seat and the passenger seat, wherein the middle armrest comprises an armrest backrest and an armrest cushion, wherein the armrest backrest is hinged above the armrest cushion, and the hinge point is located at the rear ends of the two; an armrest slide rail assembly is arranged at the bottom of the middle armrest, wherein the middle armrest can be adjusted by sliding forward and backward through the armrest slide rail assembly, and the sliding stroke is located between the front row position and the rear row position of the car; when the middle armrest slides to the front row position and the armrest backrest is laid flat forward, the middle armrest can be used as the front row armrest, when the middle armrest slides to the front row position and the armrest backrest is flipped backward from the flat state to the upright state, the middle armrest can be used as the front row middle seat, and when the middle armrest slides to the front end of the rear row position and the armrest backrest is laid flat forward, the middle armrest can be used as a desk for the rear row seat.

[0006] In the above scheme: the armrest backrest and the armrest cushion are hinged by the angle adjuster, and the hinge point is located at the intersection of the top of the armrest cushion and the bottom of the armrest backrest. An interactive structure is arranged between the middle armrest and the passenger seat. The interactive structure includes a cable and a cable handle. The cable handle is installed on the right side wall of the top of the armrest cushion through vertical rotation of the middle part. The front end of the cable handle extends to the outside of the top of the armrest cushion. A sleeve with a closed left end and an open right end is arranged on the right side wall of the lower end of the armrest cushion. , a linkage shaft is inserted in the sleeve, a connecting bracket is arranged at the left end of the cushion of the passenger seat, and a connecting hole matching the linkage shaft is arranged on the connecting bracket; when the middle armrest is used as the front middle seat, the right end of the linkage shaft passes through the sleeve and extends into the connecting hole, so that the middle armrest and the passenger seat are connected together, a spring is arranged between the left end of the linkage shaft and the sleeve, one end of the cable is connected to the rear end of the cable handle, and the other end passes through the outer wall of the sleeve from left to right and extends into the interior of the sleeve and is connected to the left end of the linkage shaft;

[0007] A limit stop is set on the right side wall at the bottom of the armrest backrest. When the armrest backrest is flipped forward from the upright state and laid flat, the limit stop can contact the front end of the cable handle and drive it to rotate, thereby driving the cable to pull the linkage shaft into the sleeve, so that the linkage shaft moves left and withdraws from the connecting hole, realizing the separation of the middle armrest and the passenger seat; when the armrest backrest is flipped backward from the flat state to the upright state, the limit stop retracts, the spring releases the elastic force, and the linkage shaft can move rightward under the action of the spring elastic force and extend into the connecting hole, realizing the connection between the middle armrest and the passenger seat. After the middle armrest and the passenger seat are separated, the two seats can move independently. After the middle armrest and the passenger seat are connected, the two seats can be linked. This design eliminates the limitations of the traditional passenger seat and middle armrest movement.

[0008] In the above scheme: the driver's seat and the passenger seat are both equipped with a seat slide assembly and a horizontal rotation mechanism. The driver's seat and the passenger seat can be adjusted to slide forward and backward through the seat slide assembly, and the sliding stroke is located between the front and rear positions of the car. The driver's seat and the passenger seat can be rotated 360 degrees horizontally relative to the seat slide assembly through the horizontal rotation mechanism; when the middle armrest slides to the middle position of the stroke and the armrest backrest is laid forward and flat, the driver's seat and the passenger seat can slide backward to the front end of the middle armrest and rotate backward, thereby forming a conference mode. When the front and rear passengers need to talk face to face, entertain or hold a meeting, the seat assembly can be adjusted to the conference mode.

[0009] In the above scheme: the armrest slide rail assembly includes a lower slide rail fixed on the vehicle body floor and an upper slide rail fixed on the bottom of the armrest cushion. The upper slide rail and the lower slide rail are slidably matched. The lower slide rail extends from the front row position to the rear row position of the car. The structure is simple, and the maximum sliding stroke of the middle armrest can be determined by setting the extension length of the lower slide rail.

[0010] In the above scheme: the middle armrest is fixedly connected to the upper slide rail through a floor lock mechanism, and the floor lock mechanism includes a floor lock fixed on the middle armrest and a lock hook fixed on the upper slide rail, the floor lock is locked on the lock hook, and the floor lock is controlled by an unlocking handle, and the unlocking handle is connected to the floor lock through a pull wire, and the unlocking handle pulls the pull wire to unlock the floor lock, so that the middle armrest can be quickly removed from the upper slide rail. Through the cooperation of the floor lock and the lock hook, the middle armrest can be quickly installed and removed from the upper slide rail. When all functions of the middle armrest are not needed, the middle armrest can be quickly removed to expand the space for the driver and the co-driver.

[0011] In the above scheme: a limit bracket is arranged on the top of the armrest cushion, and when the right end of the linkage shaft is inserted into the connection hole and the left end is inserted into the sleeve, the rear end of the cable handle is pressed downward against the limit bracket under the elastic force of the spring. The limit bracket is used to prevent the linkage shaft from coming out of the sleeve due to excessive release of the elastic force of the spring when the armrest backrest is flipped backward from the flat state to the upright state, that is, the limit bracket is used to limit the rightward movement of the linkage shaft to ensure that the linkage shaft will not come out of the sleeve.

[0012] In the above scheme: two sleeves are arranged on the right side wall of the armrest cushion, the two sleeves are arranged at intervals front and back, each sleeve is equipped with a linkage shaft and a spring, the passenger seat and the middle armrest are connected together through two linkage shafts, and the two linkage shafts are controlled by the same cable handle, and two connections are set to ensure the stability of the connection.

[0013] In the above solution: a cup holder is arranged on the back of the armrest backrest, which has the cup holder function and further increases the versatility of the middle armrest.

[0014] The beneficial effect of the present invention is that by adjusting the front and rear positions of the middle armrest and the position state of the armrest backrest, the middle armrest can be used as a front armrest, a front middle seat or a desk for the rear seat. Passengers can choose as needed to quickly switch the usage scenario of the middle armrest, which effectively solves the problem of single usage scenario of the middle armrest in the prior art and improves the convenience of use and riding comfort of the seat assembly.

[0027] The middle armrest 10 includes an armrest backrest 101 and an armrest cushion 102. The armrest backrest 101 is hinged above the armrest cushion 102, and the hinge point is located at the rear end of the two. An armrest slide rail assembly 11 is arranged at the bottom of the middle armrest 10. The middle armrest 10 can be slid forward and backward through the armrest slide rail assembly 11, and the sliding stroke is located between the front row and the rear row of the car.

[0028] When the middle armrest 10 slides to the front row position and the armrest backrest 101 is laid flat forward, the middle armrest 10 can be used as a front row armrest; when the middle armrest 10 slides to the front row position and the armrest backrest 101 is flipped backward from a flat state to an upright state, the middle armrest 10 can be used as a front row middle seat; when the middle armrest 10 slides to the front end of the rear row position and the armrest backrest 101 is laid flat forward, the middle armrest 10 can be used as a desk for the rear row seats.

[0029] Preferably, the armrest backrest 101 and the armrest cushion 102 are hinged by a recliner, and the hinge point is located at the intersection of the top of the armrest cushion 102 and the bottom of the armrest backrest 101. An interactive structure is provided between the middle armrest 10 and the passenger seat 2, and the interactive structure includes a cable 3 and a cable handle 4. The cable handle 4 is installed on the right side wall of the top of the armrest cushion 102 through a vertical rotation of its middle part, and the front end of the cable handle 4 extends to the outside of the top of the armrest cushion 102. A sleeve 5 with a closed left end and an open right end is provided to the right on the right side wall of the lower end of the armrest cushion 102, and a linkage shaft 6 is inserted in the sleeve 5. A connecting bracket 201 is provided at the left end of the cushion of the passenger seat 2, and a connecting hole matching the linkage shaft 6 is provided on the connecting bracket 201. When the middle armrest 10 is used as the middle seat in the front row, the right end of the linkage shaft 6 passes through the sleeve 5 and extends into the connecting hole, so that the middle armrest 10 and the passenger seat 2 are connected together. A spring 7 is arranged between the left end of the linkage shaft 6 and the sleeve 5. One end of the cable 3 is connected to the rear end of the cable handle 4, and the other end passes through the outer wall of the sleeve 5 from left to right and extends into the interior of the sleeve 5 and is connected to the left end of the linkage shaft 6.

[0030] A limit stop point 8 is provided on the right side wall at the bottom of the armrest backrest 101 .

[0031] When the armrest backrest 101 is flipped forward and laid flat from an upright state, the limit stop point 8 can contact the front end of the cable handle 4 and drive it to rotate, thereby driving the cable 3 to pull the linkage shaft 6 into the sleeve 5, causing the linkage shaft 6 to move left and withdraw from the connecting hole, thereby realizing the separation of the middle armrest 10 and the passenger seat 2.

[0032] When the armrest backrest 101 is flipped backward from the flat state to the upright state, the limit stop point 8 retracts, the spring 7 releases the elastic force, and the linkage shaft 6 can move rightward under the elastic force of the spring 7 and extend into the connection hole to realize the connection between the middle armrest 10 and the passenger seat 2. After the middle armrest 10 and the passenger seat 2 are separated, the two seats can move independently. After the middle armrest 10 and the passenger seat 2 are connected, the two seats can be linked. This design eliminates the limitation of the movement of the traditional passenger seat 2 and the middle armrest 10.

[0033] Preferably, the driver's seat 1 and the passenger seat 2 are both equipped with a seat slide assembly 12 and a horizontal rotation mechanism. The driver's seat 1 and the passenger seat 2 can both be adjusted to slide forward and backward through the seat slide assembly 12, and the sliding stroke is located between the front and rear positions of the car. The driver's seat 1 and the passenger seat 2 can both be rotated 360° horizontally relative to the seat slide assembly 12 through the horizontal rotation mechanism. When the middle armrest 10 slides to the middle position of the stroke and the armrest backrest 101 is laid forward and flat, the driver's seat 1 and the passenger seat 2 can slide backward to the front end of the middle armrest 10 and rotate backward, thereby forming a conference mode. When the front and rear passengers need to talk face to face, entertain or have a meeting, the seat assembly can be adjusted to conference mode.

[0034] Preferably, the armrest slide rail assembly 11 includes a lower slide rail 111 fixed to the vehicle body floor and an upper slide rail 112 fixed to the bottom of the armrest cushion 102. The upper slide rail 112 and the lower slide rail 111 are slidably matched. The lower slide rail 111 extends from the front row position to the rear row position of the car. The structure is simple, and the maximum sliding stroke of the middle armrest 10 can be determined by setting the extension length of the lower slide rail 111.

[0035] Preferably, the middle armrest 10 is fixedly connected to the upper slide rail 112 via a floor lock mechanism A, which includes a floor lock 13 fixed to the middle armrest 10 and a lock hook 14 fixed to the upper slide rail 112, the floor lock 13 is locked to the lock hook 14, and the floor lock 13 is controlled by an unlocking handle 15; the unlocking handle 15 is connected to the floor lock 13 via a pull wire 16, and the unlocking handle 15 pulls the pull wire 16 to unlock the floor lock 13, so that the middle armrest 10 can be quickly removed from the upper slide rail 112. The cooperation between the floor lock 13 and the lock hook 14 can realize the rapid installation and removal of the middle armrest 10 on the upper slide rail 112, and when all functions of the middle armrest 10 are not needed, the middle armrest 10 can be quickly removed to expand the space for the driver and the co-driver.

[0036] Preferably, a limit bracket 9 is provided on the top of the armrest cushion 102. When the right end of the linkage shaft 6 is inserted into the connection hole and the left end is inserted into the sleeve 5, the rear end of the cable handle 4 is pressed downward against the limit bracket 9 under the elastic force of the spring 7. The limit bracket 9 is used to prevent the linkage shaft 6 from coming out of the sleeve 5 due to excessive elastic force released by the spring 7 during the process of the armrest backrest 101 being flipped backward from the flat state to the upright state, that is, the limit bracket 9 is used to limit the rightward movement of the linkage shaft 6 to ensure that the linkage shaft 6 will not come out of the sleeve 5.

[0037] The sleeve 5 is a metal sleeve, and a plastic sleeve 17 is provided between the linkage shaft 6 and the sleeve 5 to reduce the friction between the linkage shaft 6 and the metal sleeve when the linkage shaft 6 moves, thereby preventing abnormal noise from occurring when the linkage shaft 6 moves.
