On the contrary, these embodiments are provided so that the present invention can be more thoroughly understood and the scope of the present invention can be fully conveyed to those skilled in the art.
[0035] In a first aspect, referring to Figures 1 to 4 , an embodiment of the present invention discloses a vehicle seat, including a seat cushion assembly 1. The seat cushion assembly 1 includes a seat cushion support 11, a seat cushion body 12, and a first drive assembly. The first drive assembly is used to drive the seat cushion body 12 to move relative to the seat cushion support 11. The first drive assembly includes two first drive mechanisms 13 spaced apart along a first direction. Each first drive mechanism 13 includes a first drive member 131, and the two first drive members 131 are symmetrically arranged. The seat cushion support 11 includes a mounting shaft 111. The mounting shaft 111 includes a main body section and two mounting sections 1111 connected to both ends of the main body section. The two first drive mechanisms 13 are respectively connected to the two mounting sections 1111. Along a second direction, the size of the mounting section 1111 is greater than or equal to the size of the main body section, and the second direction intersects the first direction. The mounting section 1111 is provided with a strengthening structure.
[0036] Among them, the vehicle seat can be a co - pilot seat. The first direction can be the width direction of the vehicle seat, and the first direction can be referred to as the direction shown by the B arrow in Figure 1 , Figure 2 , Figure 4 . The first drive member 131 can be a first motor. The second direction is preferably perpendicular to the first direction. The second direction can be the length direction of the vehicle seat, and the second direction can be referred to as the direction shown by the C arrow in Figure 1 , Figure 4 . Each first drive mechanism 13 further includes a lead screw assembly 132 connected to the first drive member 131. The first drive member 131 drives the seat cushion body 12 to move relative to the seat cushion support 11 through the lead screw assembly 132.
[0037] The two mounting sections 1111 are respectively connected to both ends of the main body section along the first direction. Along the first direction, the length of the main body section is greater than that of the mounting section 1111. The cross-sectional shape of the mounting shaft 111 can be circular. At this time, along the second direction, the dimension of the mounting section 1111 is the diameter of the mounting section 1111, and the dimension of the main body section is the diameter of the main body section. The diameter of the mounting section 1111 can be greater than the diameter of the main body section or equal to the diameter of the main body section. Preferably, the diameter of the mounting section 1111 is greater than the diameter of the main body section. The strengthening structure can include a plurality of reinforcing ribs.
[0038] In the embodiment of the present utility model, a first driving member 131 is added to the vehicle seat. The two first driving members 131 are symmetrically arranged on the seat cushion support member 11. For a vehicle with an aluminum body, during the 25% offset collision of the China Insurance Research Institute, the two symmetrically arranged first driving members 131 can make the vehicle seat receive force evenly, and it is not easy to cause the seat to deform and collapse, and can meet the 25% offset collision performance requirements of the China Insurance Research Institute, greatly improving the safety of the seat. In addition, along the second direction, the dimension of the mounting section 1111 is greater than or equal to the dimension of the main body section. The mounting section 1111 is provided with a strengthening structure, which enhances the strength of the mounting section 1111, that is, enhances the strength of the connection part of the first driving mechanism 13, and can meet the setting of the two first driving mechanisms 13. In addition, through the setting of the two first driving mechanisms 13, the force on the seat cushion main body 12 during movement is more uniform, so as to ensure the smooth movement of the seat cushion main body 12, and when one of the first driving mechanisms 13 fails, the other first driving mechanism 13 can still work normally.
[0039] In a preferred embodiment of the present utility model, referring to Figure 3 and Figure 4 , a chute 1121 is formed on the seat cushion support member 11. The seat cushion main body 12 is connected with a sliding shaft 15, and the sliding shaft 15 is slidably connected to the chute 1121; the seat cushion main body 12 is connected to the seat cushion support member 11 through a connecting member 14. One end of the connecting member 14 is rotatably connected to the seat cushion main body 12, and the other end of the connecting member 14 is rotatably connected to the seat cushion support member 11. The end of the lead screw assembly 132 away from the first driving member 131 is connected to the connecting member 14.
[0040] Among them, the seat cushion support member 11 includes two first frames 112 arranged at intervals along the first direction, and the chute 1121 is formed on the first frame 112. The seat cushion main body 12 includes two second frames 121 arranged at intervals along the first direction, and the two second frames 121 are connected by a sliding shaft 15 and a connecting shaft 122. The sliding shaft 15 is slidably connected to the chute 1121. Through the setting of the chute 1121, the movement track of the seat cushion main body 12 can be restricted to ensure the accuracy of the movement of the seat cushion main body 12.
[0041] One end of the connecting member 14 close to the seat cushion main body 12 is specifically rotatably connected to the connecting shaft 122. The number of the connecting members 14 is two, and the two connecting members 14 are spaced apart along the first direction. The two lead screw assemblies 132 are respectively connected to the two connecting members 14. One end of the lead screw assembly 132 away from the first driving member 131 is specifically rotatably connected to the connecting member 14, and one end of the lead screw assembly 132 close to the first driving member 131 is rotatably connected to the connecting bracket 113.
[0042] When the first driving member 131 is a first motor, the first motor drives the seat cushion main body 12 to move along the sliding groove 1121 through the lead screw assembly 132 and the connecting member 14. The lead screw assembly 132 includes a transmission mechanism, a lead screw, a ball nut connected to the lead screw, and a telescopic rod connected to the ball nut. The telescopic rod is connected to the connecting member 14. The output shaft of the first motor is connected to the lead screw through the transmission mechanism. The first motor is used to drive the lead screw to rotate. When the lead screw rotates, the ball nut moves on the lead screw, and the movement of the ball nut drives the telescopic rod to move.
[0043] The vehicle seat further includes a backrest assembly 2, and the backrest assembly 2 is rotatably connected to the seat cushion assembly 1. The sliding groove 1121 has a first end close to the connection between the backrest assembly 2 and the seat cushion assembly 1 and a second end far from the connection between the backrest assembly 2 and the seat cushion assembly 1. The first end of the sliding groove 1121 is higher than the second end. Initially, the sliding shaft 15 is located at the first end of the sliding groove 1121. When the first motor works, it drives the lead screw to rotate. When the lead screw rotates, the ball nut moves forward on the lead screw. The forward movement of the ball nut drives the telescopic rod to extend forward. The telescopic rod pushes the connecting member 14 to rotate. When the connecting member 14 rotates, it drives the seat cushion main body 12 to move forward. At the same time, the sliding shaft 15 moves towards the second end of the sliding groove 1121, so that the seat cushion main body 12 moves downward.
[0044] In a preferred embodiment of the present utility model, the cross-sectional shape of the installation section 1111 is circular, the diameter of the installation section 1111 is greater than or equal to 25 mm and less than or equal to 30 mm; the cross-sectional shape of the main body section is circular, and the diameter of the main body section is smaller than the diameter of the installation section 1111. Among them, the diameter of the installation section 1111 can be 25 mm, 26 mm, 27 mm, 28 mm, 30 mm, etc. The diameter of the installation section 1111 is preferably 25 mm. When the diameter of the installation section 1111 is within the above range, the strength of the installation section 1111 is ensured. The diameter of the main body section is smaller than the diameter of the installation section 1111. Compared with the setting where the diameter of the main body section is equal to the diameter of the installation section 1111, the weight of the installation shaft 111 is reduced, which is beneficial to the lightweight of the vehicle seat.
[0045] In a preferred embodiment of the present utility model, the first driving member 131 is a first motor, and the two first motors are electrically connected to a synchronous controller. The synchronous controller is used to control the synchronous rotation speed of the two first motors.
[0046] Wherein, a rotational speed sensor can be arranged on the output shaft of each first motor. The rotational speed sensor is electrically connected to the synchronization controller, and the synchronization controller monitors the rotational speeds of the two first motors through the rotational speed sensor. If the rotational speed of one of the first motors is too fast, the synchronization controller will compensate for the rotational speed of the first motor with too fast rotational speed to reduce the rotational speed of the first motor to be consistent with that of the other first motor, so as to keep the rotational speeds of the two first motors synchronized.
[0047] If the rotational speeds of the two first motors are inconsistent, one of the first motors with too large rotational speed will cause excessive sliding stress, resulting in abnormal noise and flutter. In the embodiment of the present utility model, by monitoring the rotational speeds of the two first motors through the synchronization controller and balancing the rotational speeds of the two first motors to keep the rotational speeds of the two first motors consistent, it is possible to avoid abnormal noise during the movement of the seat cushion body.
[0048] In a preferred embodiment of the present utility model, the installation section 1111 has an inner hole, and the strengthening structure includes a first reinforcing rib assembly arranged in the inner hole of the installation section 1111; and / or, the strengthening structure includes a second reinforcing rib assembly arranged on the outer surface of the installation section 1111. Wherein, the first reinforcing rib assembly includes a plurality of first reinforcing ribs, and the shape of the first reinforcing rib can be annular, strip-shaped, spiral-shaped, etc. The second reinforcing rib assembly includes a plurality of second reinforcing ribs, and the shape of the second reinforcing rib can be annular, strip-shaped, spiral-shaped, etc. Through the arrangement of the first reinforcing rib assembly and / or the second reinforcing rib assembly, the strength of the installation section 1111 is enhanced, that is, the strength of the connection part of the first driving mechanism 13 is enhanced, and the setting of the two first driving mechanisms 13 can be satisfied.
[0049] In a preferred embodiment of the present utility model, referring to Figure 4 , each first driving mechanism 13 includes a lead screw assembly 132 connected to the first driving member 131. The lead screw assembly 132 is connected to the installation section 1111 through a connection bracket 113; the lead screw assembly 132 includes a lead screw, and the diameter of the lead screw is greater than or equal to 5 mm and less than or equal to 8 mm. The diameter of the lead screw can be 5 mm, 6 mm, 7 mm, 8 mm, etc. The diameter of the lead screw is preferably 8 mm. When the diameter of the lead screw is within the above range, it can ensure that the lead screw has sufficient strength and stiffness. In addition, due to the setting of the two first driving mechanisms 13, compared with only setting one first driving mechanism 13, without affecting the driving force, the diameter of the lead screw can be reduced to less than or equal to 8 mm, avoiding excessive increase in the weight of the vehicle seat and facilitating the lightweight of the vehicle seat.
[0050] In a preferred embodiment of the present utility model, along the first direction, the length of the first motor is less than or equal to 120 millimeters, and along the second direction, the width of the first motor is less than or equal to 40 millimeters. The length of the first motor is preferably 120 millimeters, and the width of the first motor can be 38 mm, 39 mm, 40 mm, etc. Due to the arrangement of the two first driving mechanisms 13, compared with only setting one first driving mechanism 13, without affecting the driving force, the size of the first motor can be reduced to the above size range, avoiding excessive increase in the weight of the vehicle seat and facilitating the lightweight of the vehicle seat.
[0051] In a preferred embodiment of the present utility model, referring to Figure 1 , the vehicle seat further includes a backrest assembly 2, and the backrest assembly 2 is rotatably connected to the seat cushion assembly 1; the vehicle seat has a folded state and a use state, and the angle between the backrest assembly 2 and the seat cushion assembly 1 in the folded vehicle seat is smaller than the angle between the backrest assembly 2 and the seat cushion assembly 1 in the used vehicle seat.
[0052] The vehicle seat further includes a second driving mechanism, and the second driving mechanism is used to drive the backrest assembly 2 to rotate relative to the seat cushion assembly 1 so that the vehicle seat can be switched between the folded state and the use state. The second driving mechanism may include a second motor. In this embodiment, the vehicle seat can be folded when not in use to reduce the space occupied by the vehicle seat and provide more activity space for the rear passengers.

[0054] Among them, the control module can be the in-vehicle computer in the vehicle. The number of pressure sensors is preferably at least two. During the folding process of the vehicle seat, the control module can control the switch to open. At this time, the control module can monitor the pressure on the side of the backrest assembly 2 facing the seat cushion assembly 1 through the pressure sensor. During the folding process of the vehicle seat, there may be items placed on the seat cushion assembly 1. At this time, if the folding of the vehicle seat continues, the second driving mechanism and the items will be damaged. In this embodiment, during the folding process of the vehicle seat, when there are items placed on the seat cushion assembly 1, the backrest assembly 2 rotates to contact the items, and when the backrest assembly 2 continues to rotate towards the seat cushion assembly 1, the pressure monitored by the pressure sensor will increase. When the pressure is greater than the first set value, the control module controls the second driving mechanism to stop working to control the vehicle seat to stop folding, so as to avoid damage to the second driving mechanism and the items caused by the continuous folding of the vehicle seat. In this embodiment, through the setting of the pressure sensor, it is possible to determine whether there is an abnormal situation during the folding process of the vehicle seat.
[0055] The gravity sensor is used to monitor the gravity on the seat cushion assembly 1 to determine whether there is a passenger on the seat cushion assembly 1, that is, through the gravity sensor, it is possible to detect whether there is a passenger on the vehicle seat. A distance sensor is provided at one end of the seat cushion assembly 1 along the second direction close to the connection between the backrest assembly 2 and the seat cushion assembly 1. The distance sensor is specifically used to monitor the distance between the vehicle seat and the rear seat, so as to move the vehicle seat to a position suitable for the rear passengers to rest their feet.
