[0015] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention, and does not strictly limit the scope of protection of the specific claims of the present invention.

[0016] Embodiment 1: like Figure 1-Figure 5 As shown, a seat plate assembly for a wheelchair comprises a first base 3 and a seat plate body 1, wherein the first base 3 can be fixedly connected to a wheelchair frame, a horizontal moving mechanism is installed on the first base 3, an unlocking connection structure is installed on the horizontal moving mechanism, and the seat plate body 1 is installed on the unlocking connection structure; At this time, when the patient in the wheelchair needs to be carried to the car seat, the car door is opened, and the wheelchair is pushed to one side of the car door opening, and the seat plate body 1 is driven to move horizontally by the horizontal moving mechanism, and the seat plate body 1 is moved through the car door opening to above the car seat, and then the unlocking connection structure is unlocked, so that the unlocking connection structure and the seat plate body 1 are separated, and the seat plate body 1 can be moved to the seat, so that the patient on the seat plate body 1 can be moved to the car seat with relatively little effort; When the patient needs to be moved from the seat to the wheelchair, the wheelchair is pushed to the side of the car door again, and the unlocking connecting structure is driven by the horizontal moving mechanism to move horizontally. When the unlocking connecting structure moves to the interior of the car and is opposite to the seat plate body 1, the seat plate body 1 and the horizontal moving mechanism can be connected by the unlocking connecting structure, and the seat plate body 1 is driven to move by the horizontal moving mechanism. The seat plate body 1 is moved to the upper side of the first base 3, and the patient inside the seat plate body 1 can be moved from the car seat to the wheelchair with less effort.

[0017] Among them, Figure 1-Figure 3As shown, a backrest 2 is fixedly connected to the rear side of the upper side of the first base 3, and armrests 24 are fixedly connected to both sides of the front side of the backrest 2. The backrest 2 can provide support for the patient's back, and the armrests 24 can provide support for the patient's hands, thereby effectively improving the stability of the patient on the first base 3 during the movement of the first base 3.

[0018] At the same time, safety belts can also be installed on the seat plate body 1 and the back plate 2 to restrain and protect the patient.

[0019] like Figure 1-Figure 3 As shown, the horizontal moving mechanism can be an electric moving mechanism or a manual moving mechanism; Among them, the electric moving mechanism can be an electric telescopic rod, which is fixedly connected to the first base 3, and can drive the unlocking connection structure and the seat plate body 1 connected thereto to move through the electric telescopic rod, and has good self-locking performance.

[0020] like Figure 1-Figure 3 As shown, the horizontal moving mechanism in the present technical solution is preferably a manual moving mechanism, which includes a main rail body 5 fixedly connected to the upper side of the first base 3. The number of the main rail bodies 5 is preferably two, and a slide bar 6 is slidably connected to the main rail body 5. The unlocking connection structure is installed on the slide bar 6. At this time, the unlocking connection structure and the seat plate body 1 can be driven to move by sliding the slide bar 6.

[0021] In addition, a locking piece compatible with the slide bar 6 can be installed on the main rail body 5 to lock the slide bar 6 after the slide bar 6 is reset. The locking piece can be a locking screw threadedly connected to the main rail body 5. The slide bar 6 can be locked by the abutment between the locking screw and the slide bar 6.

[0022] An electric transmission mechanism compatible with the slide bar 6 can also be installed on the first base 3, and the electric transmission mechanism includes a transmission motor fixedly connected to the first base 3, and the output end of the transmission motor is fixedly connected to a gear. A horizontal gear groove is opened on the slide bar 6, and the gear and the horizontal gear groove are meshed and connected. By starting the transmission motor to drive the gear to rotate, the slide bar 6 can be pushed.

[0023] Among them, Figure 2 and Figure 5As shown, the unlocking connection structure can be a clamp, an electromagnet or a screw connection. In the present technical solution, a screw connection is preferred. Specifically, the unlocking connection structure includes a connection block 11 located on one side of the seat plate body 1. The connection block 11 and the slide bar 6 are fixedly connected. At this time, when the slide bar 6 moves, the connection block 11 can be driven to move. A through hole is provided inside the connection block 11, and a connecting screw 12 is inserted inside the through hole. A threaded hole opposite to the connecting screw 12 is provided on the seat plate body 1. The connecting screw 12 can be threadedly connected to the inside of the threaded hole, so that the seat plate body 1 and the connection block 11 are connected by the connecting screw 12. The connection is relatively stable, the structure is relatively simple, and the operation is relatively convenient.

[0024] Specifically, Figure 1-Figure 2 and Figure 5 As shown, a vertical track 7 is fixedly connected to the slide bar 6, a first threaded rod 8 is rotatably connected inside the vertical track 7, a lower extending connecting bracket 10 is threadedly connected to the outer side of the first threaded rod 8, the lower extending connecting bracket 10 is fixedly connected to the connecting block 11, and the lower extending connecting bracket 10 is slidably connected to the vertical track 7, a servo motor 9 is fixedly connected to the upper side of the vertical track 7, and the output end of the servo motor 9 is fixedly connected to the first threaded rod 8. At this time, the first threaded rod 8 can be driven to rotate by starting the servo motor 9, and the first threaded rod 8 When rotating, the lower extending connecting bracket 10 will be driven to rotate, and the height of the seat plate body 1 will be adjusted to adapt to the height difference between the slide bar 6 and the car seat. When the seat plate body 1 is moved onto the car seat, the lower extending connecting bracket 10 will move to make the seat plate body 1 fall on the car seat. When the seat plate body 1 is moved out of the car seat, the connecting block 11 and the seat plate body 1 will be connected, and then the seat plate body 1 will be lifted by moving the lower extending connecting bracket 10, so as to reduce the friction between the seat plate body 1 and the car seat when it moves.

[0025] like Figure 1-Figure 3 As shown, the seat plate assembly also includes a slide rod 14, one end of which is fixedly connected to an upper extending connecting bracket 15, and a first electric push rod 16 is fixedly connected to the upper extending connecting bracket 15, and a pad 17 is fixedly connected to the output end of the first electric push rod 16. A slide groove 13 is provided inside the slide bar 6, and the slide rod 14 can be inserted into the inside of the slide groove 13. At this time, when sliding the slide bar 6, the pad 17 is placed on the car seat, and the two ends of the slide bar 6 can be supported by the wheelchair frame and the first electric push rod 16 respectively, thereby reducing the force applied by the user to reinforce the wheelchair during the movement of the seat plate 1 and the slide bar 6.

[0026] At the same time, the pad 17 can also be replaced with a moving wheel to facilitate the movement of the first electric push rod 16 on the seat.

[0027] Among them, Figure 1-Figure 3As shown, both ends of the main rail body 5 are rotatably connected with the auxiliary rail body 23, and the connection method of the auxiliary rail body 23 can be a hinge connection or a shaft connection. The auxiliary rail body 23 is initially rotated to a vertical setting, thereby reducing the volume of the seat plate assembly when it is stored. When the seat plate body 1 is moved, the auxiliary rail body 23 can be rotated to a horizontal state, so that the auxiliary rail body 23 and the main rail body 5 form an extended track for the slide bar 6 to slide, thereby increasing the sliding length of the slide bar 6; Although the end of the auxiliary guide rail body 23 away from the main guide body 5 can be supported by the pad 17 and the slide rod 14, in order to further improve the stability of the auxiliary guide rail body 23, the present technical solution chooses to fix a first guide ring 18 on the outer side of the main guide body 5, and a second guide ring 19 on the outer side of the auxiliary guide rail body 23, and the inside of the first guide ring 18 is connected to an insert plate 20, which can slide into the inside of the second guide ring 19, so that the connection between the main guide body 5 and the auxiliary guide body 23 can be reinforced by the insert plate 20.

[0028] Furthermore, a positioning magnet 21 may be fixedly connected to the first guide ring 18 . The material of the plug plate 20 is iron. The plug plate 20 may be adsorbed and positioned by the positioning magnet 21 .

[0029] At the same time, the seat plate assembly also includes a second base 4 located at the lower side of the first base 3, and a second electric push rod 22 is fixedly connected to the second base 4. The piston rod of the second electric push rod 22 is fixedly connected to the first base 3. The second base 4 is fixedly connected to the wheelchair frame. By starting the second electric push rod 22, the height of the first base 3 can be adjusted, thereby effectively adjusting the height of the seat plate body 1 to make it compatible with the car seat.

[0030] Embodiment 2: like Figure 1 and Figure 6-Figure 7 As shown, this embodiment improves the structure of the armrest 24 on the basis of the first embodiment, so that the seat plate body 1 can be well adapted to the safety belt, and the seat plate body 1 can be well positioned by the safety belt.

[0031] Specifically, the armrest 24 includes a transverse connecting rod 25 fixedly connected to the front side of the backrest 2, the front end of the transverse connecting rod 25 is fixedly connected to a connecting ring 26, the inside of the connecting ring 26 is vertically slidably connected to a vertical connecting rod 27, the upper side of the seat plate body 1 is fixedly connected to a positioning block 30, the lower end of the vertical connecting rod 27 is provided with a positioning groove, the lower end of the vertical connecting rod 27 is clamped on the outer side of the positioning block 30 through the positioning groove, so that the vertical connecting rod 27 can be stably positioned, and a connecting rod positioning screw 28 is threadedly connected to the connecting ring 26, and the vertical connecting rod 27 can be locked by the connecting rod positioning screw 28.

[0032] When the seat plate body 1 is placed on the car seat, the vertical connecting rod 27 is moved upward to form an opening between the vertical connecting rod 27 and the seat plate body 1, and the waist belt part of the safety belt is placed through the above-mentioned opening into between the seat plate body 1 and the transverse connecting rod 25, so that the waist belt can fully fit the patient, reducing the phenomenon of a large space between the waist belt and the patient caused by the vertical connecting rod 27 stretching the waist belt, thereby reducing the safety hazard caused by the large space between the safety belt and the patient.

[0033] At the same time, a locking hole 29 is opened at the upper end of the vertical connecting rod 27. When the connecting rod positioning screw 28 is inserted into the locking hole 29, the vertical connecting rod 27 can be locked more stably.

[0034] like Figure 6-Figure 7 As shown, the upper and lower sides of one side of the backboard 2 are fixedly connected with a safety belt connector 31, and the lower side of the other side of the backboard 2 is also fixedly connected with a safety belt connector 31. The safety belt connector 31 is used as a fixing point for the safety belt to limit the position of the safety belt, and the seat plate 1 and the backboard 2 can be positioned through the safety belt.

[0035] Specifically, the safety belt connector 31 includes a U-shaped frame 32 fixedly connected to the side of the back plate 2, a second threaded rod 33 is threadedly connected to the U-shaped frame 32, one end of the second threaded rod 33 is rotatably connected to a clamping plate 34 located inside the U-shaped frame 32, and a guide rod 35 is fixedly connected to the clamping plate 34 and slidably connected to the U-shaped frame 32. At this time, the shoulder strap or waist belt portion of the safety belt is placed into the interior of the U-shaped frame 32, and then the second threaded rod 33 is rotated to drive the clamping plate 34 to push, so that the safety belt is clamped to complete the connection between the safety belt and the seat plate body 1 and the back plate 2.

[0036] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art unless otherwise specified and limited.
