As shown in fig. 1-5, the vehicle of the present invention includes a vehicle body 10 and a seat cushion assembly. The seating pad assembly is disposed on the vehicle body 10 and is rotatable relative to the vehicle body 10 by a rotation shaft 12. The seat cushion assembly includes a holster 21, a cushion pad 22, a first base 23, a second base 24, a detector 25, and a wire harness. Wherein the cushion pad 22 is disposed above the first base 23. The leather sheath 21 is sleeved on the cushion pad 22 and the first base 23. The first base 23 is connected to the second base 24. The detecting member 25 is disposed between the cushion pad 22 and the first base 23, and detects an external force applied to the cushion pad 22.

As shown in fig. 1 to 5, the first base 23 is substantially plate-shaped, and a detection piece groove 231 is provided in the middle of the upper surface thereof. Which is formed to be depressed downward from the upper surface of the first base 23. The shape of the detecting member groove 231 matches the shape of the detecting member 25 for accommodating the detecting member 25. Specifically, the detector groove 231 is substantially elongated and extends in the left-right direction. The left and right ends of the sensing piece groove 231 are provided at the bottom thereof with a first drain hole 232 and a second drain hole 233, respectively. The first and second drain holes 232 and 233 penetrate the first base 23 in the thickness direction of the first base 23 so that water on the upper surface of the first base 23 can flow out of the first base 23. The first base 23 is further provided with a first communication port 235. Which penetrates the first base 23 in the thickness direction of the first base 23 so that the wire harness connected to the detection member 25 can pass through the first base 23. The first base 23 is further provided with a first wire groove 234 and a second wire groove 236. The first wire groove 234 is formed to be depressed downward from the upper surface of the first base 23. A first end of the first wire groove 234 communicates with the right end of the detector groove 231, and a second end of the first wire groove 234 communicates with the first communication port 235. The second wire groove 236 is formed depressed upward from the lower surface of the first base 23. A first end of the second wire groove 236 communicates with a right end of the detector groove 231, and a second end of the second wire groove 236 is disposed substantially at a left side of a left end of the detector groove 231. Thus, the wire harness can extend from the right end of the detector 25 into the first wire groove 234, pass through the first communication port 235 from the top to the bottom, extend into the second wire groove 236, and extend in the second wire groove 236. As an example, the first base 23 is made of a plastic material.

It will be understood by those skilled in the art that although the first drain hole 232 and the second drain hole 233 are illustrated in the present invention, any number of drain holes is within the scope of the present invention.

As shown in fig. 1 to 5, the second base 24 has a substantially plate-like shape, and the outer peripheral shape thereof is substantially similar to that of the first base 23. Specifically, the second chassis 24 has a second communication port 301 at the left end. The second communication port 301 penetrates the second chassis 24 in the thickness direction of the second chassis 24 to enable the wire harness to pass through the second chassis 24. The second base 24 is disposed below the first base 23 and is connected to the second base 24 by fasteners (e.g., screws). When the first and

second bases

23 and 24 are mounted in place, the second communication port 301 is substantially opposite to the second end of the second wire groove 236, so that the wire harness can extend downward from the second end of the second wire groove 236 and then pass through the second communication port 301. Thus, when the first base 23 and the second base 24 are mounted in place, the first communication port 235 and the second communication port 301 are arranged on opposite sides of the detection member 25. As one example, the second chassis 24 is made of a metal material.

As shown in FIG. 2, cushion 22 is generally made of a cushioning material to provide comfort to a person sitting on the seat cushion. As one example, the cushion 22 is made of foam. The cushion pad 22 is disposed on the first base 23. More specifically, the lower surface of cushion 22 is substantially planar. Since the first seat 23 is provided with the detector groove 231 and the detector 25 is received in the detector groove 231, a specific structure for receiving the detector groove 231 is not provided on the lower surface of the cushion pad 22. The detecting member 25 is substantially elongated. When the detector 25 is received in the detector slot 231, the upper surface of the detector 25 is substantially flush with the upper surface of the first base 23 surrounding the detector slot 231. When the cushion pad 22 is disposed on the first base 23 and the detection member 25 and is not subjected to an external force (e.g., no one sits on the seat cushion), the lower surface of the cushion pad 22 is flush with the upper surface of the detection member 25. When the cushion pad 22 receives an external force (for example, no one sits on the seat cushion), the lower surface of the cushion pad 22 is pressed into contact with the detection piece 25, so that the detection piece 25 receives a pressure.

As shown in fig. 2, the holster 21 is generally cap-shaped, and is fitted over the cushion pad 22 and coupled to the first base 23 by a fastener (e.g., a screw) to protect the cushion pad 22.

The installation process of the seating pad assembly is described below in conjunction with fig. 1-5:

first, the operator first puts the detector 25 into the detector groove 231 of the first base 23, passes the free end of the wire harness connected to the detector 25 through the first communication port 235, and allows a portion of the wire harness to be accommodated in the first wire groove 234. The operator then places the cushion pad 22 over the detector 25 and the first base 23 and sets the epithelial sheath 21. The operator connects the holster 21 to the first base 23 via fasteners (e.g., screws) to hold the cushion 22 and the detector 25 in place. The operator then passes the free end of the wire harness through the second communication port 301 of the second chassis 24 and causes a portion of the wire harness to be received in the second wire groove 236. Finally, the operator connects the second base 24 to the first base 23 by fasteners (e.g., screws).

In the present invention, the vehicle further includes a control device provided in the vehicle body 10. The control device is in communication with the detecting member 25 via a wiring harness to receive the detection signal from the detecting member 25. As an example, in the present invention, the wiring harness includes a detector wiring harness 27 and a collector wiring harness 28 connected. The first end of the detector wire harness 27 is connected to the detector 25. The second end of the detector wire harness 27 extends into the first wire groove 234, passes through the first communication port 235 from top to bottom, and then extends into the second wire groove 236. A first end of the hub harness 28 is connected to a second end of the test piece harness 27. The second end of the hub harness 28 extends in the second wire groove 236, passes through the second communication port 301 from top to bottom, enters the vehicle body 10, and is connected to the control device. The detecting member 25 is configured to: when the detecting member 25 is pressed, the detecting member 25 sends a detection signal to the control device. In addition, a waterproof plug is used for the second end of the detector wire harness 27 and the first end of the hub wire harness 28.

In the related art, in order to dispose a detection member between a base and a cushion pad to detect an external force applied to the cushion pad. The upper surface of the base is set to be substantially flat, and a groove for accommodating the detection member is provided on the cushion pad. This arrangement may require high processing accuracy of the cushion pad and the detection member, and may not protect the wire harness. When the machining precision of blotter is not good, there is the clearance between blotter and the detection piece after the installation, and this makes the detection piece can't discern when lighter people sit on the seat pad to cause the unable normal operating of vehicle. In addition, since the cushion pad is made of a cushioning material, the machining accuracy is difficult to control.

Compared with the prior art, the seat cushion assembly at least has the following advantages:

first, the contact between the detecting member 25 and the cushion pad 22 in the seat cushion assembly of the present invention is good, and the detecting member 25 can reflect the stress state of the cushion pad 22 in time. Specifically, the seat cushion assembly of the present invention does not have another structure for receiving the detector 25 on the cushion pad 22 by providing the detector groove 231 on the first seat 23 to receive the detector 25. Thus, the lower surface of the cushion pad 22 may be provided flat and may be arranged substantially flush with the upper surface of the detection member 25. This allows cushion pad 22 and detector 25 to maintain good contact. The cushion pad 22 can press the detection piece 25 even when a light person sits on the seat cushion.

Second, the seat cushion assembly of the present invention has good drainage performance. Specifically, the seating pad assembly of the present invention provides support for the cushion pad 22 and the detector 25 by the first base 23 and the second base 24 being assembled together. The first base 23 is provided with a drainage hole to drain water that may exist above the first base 23 to below the first base 23. In addition, since the first base 23 and the second base 24 are assembled by the fastening members, a gap may exist between the first base 23 and the second base 24, and water under the first base 23 may be discharged out of the seating pad assembly through the gap.

Thirdly, the seat cushion assembly has good line protection performance and is smooth and reasonable in wiring. Specifically, the majority of the wire harness in the seating pad assembly of the present invention is generally disposed between the first seat 23 and the second seat 24, and the first seat 23 and the second seat 24 can provide good protection for the wire harness. Further, since the seat cushion assembly is able to rotate about the rotation shaft 12 with respect to the vehicle body 10, the first communication port 235 and the second communication port 301 are disposed at both ends of the detection piece 25, and the second communication port 301 on the second base 24 is disposed near the rotation shaft 12. This not only provides sufficient space for routing the wiring harness, but also does not interfere with the rotation of the seat cushion assembly relative to the vehicle body 10 so that the routing is smooth and reasonable.

The foregoing embodiments are merely illustrative of the principles and utilities of the present invention and are not intended to limit the utility model. Any person skilled in the art can modify or change the above-mentioned embodiments without departing from the spirit and scope of the present invention. Accordingly, it is intended that all equivalent modifications or changes which can be made by those skilled in the art without departing from the spirit and technical spirit of the present invention be covered by the claims of the present invention.
