[0025] The technical solution of the present invention will be further described below in conjunction with the drawings and through specific embodiments.

[0026] Combined with Figures 1 to 6 as shown, this embodiment provides a seat, including a seat cushion support assembly 1 and a backrest support assembly 2. Specifically, the seat cushion support assembly 1 includes a base 11, a seat cushion support frame 12 pivotally connected to the base 11, and a first driving mechanism 13 for adjusting the angle between the seat cushion support frame 12 and the bearing surface of the base 11.

[0027] More specifically, the base 11 includes a fixed frame 111 and support arms 112 disposed on opposite side walls of the fixed frame 111. The two support arms 112 are respectively pivotally connected to pivot seats in the middle of opposite side walls of the seat cushion support frame 12. Further, in order to have better mechanical efficiency, preferably, the support arms 112 in this embodiment are triangularly arranged and integrally provided with the fixed frame 111.

[0028] Further, in order to facilitate adjusting the angle between the seat cushion support frame 12 and the bearing surface of the base 11, that is, to make the seat cushion support frame 12 tilt forward or backward, the first driving mechanism 13 in this embodiment includes a first motor 131 installed along the length direction of the seat cushion support frame 12, two first synchronous driving shafts 132 disposed on both sides of the first motor 131 and connected to the first motor 131, two driving gears 133 respectively disposed at the ends of the two first synchronous driving shafts 132, and two racks 134 vertically pivotally connected to the fixed frame 111 and respectively meshing with the corresponding driving gears 133. Preferably, the first motor 131 and the first synchronous driving shafts 132 in this embodiment are both installed inside the front border of the seat cushion support frame 12. When it is necessary to adjust the seat cushion support frame 12, only by rotating the first motor 131 forward or backward, the forward or backward tilt of the seat cushion support frame 12 can be achieved.

[0029] More specifically, the backrest support assembly 2 in this embodiment includes a connection seat 21, a backrest 22 pivotally connected to the connection seat 21 with adjustable angle, and a second driving mechanism 23 connected to the connection seat 21 for driving the backrest 22 to move back and forth along the front and back direction of the seat cushion support frame 12.

[0030] Preferably, the second driving mechanism 23 includes tooth tracks installed along the width direction of opposite side walls of the seat cushion support frame 12, and a power driving device with both ends respectively meshing with the two tooth tracks.

[0031] In order to facilitate the installation of the power driving device and reduce the suspended weight, preferably, a support beam 121 is provided in the middle of the seat cushion support frame 12 in this embodiment, and a slideway cooperating with the power driving device is provided on the lower bottom surface of the support beam 121.

[0032] Further, the power driving device includes a second motor 231, two second synchronous driving shafts 232 disposed on both sides of the second motor 231 and respectively connected to the second motor 231, and gear sets 26 respectively disposed at the ends of the two second synchronous driving shafts 232. The gear sets 26 are engaged with the tooth track. The two connecting seats 21 are respectively rotatably connected to the corresponding second synchronous driving shafts 232, and the second motor 231 is slidably engaged with the slideway. Thus, when the second motor 231 drives the gear sets 26 at both ends to rotate, the power driving device can move back and forth along the length direction of the tooth track. Since the power driving device is connected to the backrest 22 through the connecting seat 21, it can drive the backrest 22 to move synchronously, and then change the position of the backrest 22 on the seat cushion support frame 12, that is, move from one side of the seat cushion support frame 12 to the other side, thereby changing the orientation of the occupant.

[0033] More specifically, in this embodiment, the tooth track includes an upper rack 251 and a lower rack 252 that are parallel, spaced apart, and oppositely disposed. The gear set 26 includes a driving gear 261 fastened to the second synchronous driving shaft 232, and a driven gear 262 pivotally connected to the side wall of the connecting seat 21 for meshing with the driving gear 261. The driven gear 262 is engaged with the upper rack 251, and the driving gear 261 is engaged with the lower rack 252. It is also possible to move the second synchronous driving shaft 232 upward as needed, so that the driven gear 262 is engaged with the lower rack 252, and the driving gear 261 is engaged with the upper rack 251. The gear set 26 designed in this way can not only better meet the moving speed of the backrest 22, but also cooperate with a wider tooth track to provide a relatively stable and reliable driving force.

[0034] Even more specifically, in this embodiment, the connecting seat 21 includes a first vertical wall 211, a horizontal wall 212, and a second vertical wall 213 that are integrally bent. The bent connecting seat 21 is in a Z shape. Preferably, the first vertical wall 211 is pivotally connected to the backrest 22, and the second vertical wall 213 is rotatably connected to the second synchronous driving shaft 232.

[0035] Further, the horizontal wall 212 of the installed connecting seat 21 is located above the seat cushion support frame 12, and a gap for accommodating the seat cushion is provided between the horizontal wall 212 and the backrest 22. In addition, an adjusting device for adjusting the inclination angle of the backrest 22 is provided between the first vertical wall 211 and the backrest 22, so that the adjusting device can adjust the inclination angle of the backrest 22 relative to the seat cushion surface. The specific structural design of the adjusting device in this embodiment is relatively common in related technologies and will not be specifically described here.

[0036] The present invention also provides a recreational vehicle, including the seat described above. Through the arrangement of the seat, the position of the backrest 22 and the tilt angle of the seat cushion support frame 12 can be flexibly adjusted according to the seating requirements, thereby bringing a better user experience to the passengers. In addition, since the recreational vehicle is provided with the above-mentioned seat, the utilization rate of the carriage space is also better improved, and the space occupation of the carriage is greatly reduced.

[0037] The technical principle of the present invention has been described above in conjunction with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be construed in any way as a limitation on the protection scope of the present invention. Based on the explanations herein, those skilled in the art can readily conceive of other specific embodiments of the present invention without creative efforts, and these embodiments will fall within the protection scope of the present invention.
