The projection of the center of gravity of the folded shower chair onto the plane of the self-supporting surface is located within the self-supporting surface. By setting the self-supporting surface and center of gravity design, the shower chair can stand upright on the ground through the self-supporting surface.

[0086] In this embodiment, the rear end of the base 01 is provided with two rollers, which can be used to move the bath chair, thus making it easy to move.

[0087] In this embodiment, the structure of the lifting bracket 02 can be referred to the accompanying drawings and the prior art.

[0088] In this embodiment, the chair seat 03 also includes a seat cushion assembly that can rotate relative to the chair seat body 7. The chair seat body 7 is provided with a plurality of universal ball bearings, and the seat cushion assembly is disposed on the universal ball bearings. The seat cushion assembly includes a base and a soft cushion. The seat cushion assembly is rotatable, which can avoid or reduce skin tearing caused by movement during bathing.

[0089] See Figures 9 to 13 The process of changing the state of the shower chair is described in detail. See also Figure 9 When the shower chair is folded, the lower hook 61 of the base 01 engages with the upper hook 72 of the seat 03 under the action of the second elastic force, preventing the base 01 and seat 03 from separating. At this time, the lower pressing member of the seat 03 abuts against the front and rear stops 51, pressing down on the front and rear stops 51 and compressing the first elastic member 52. The electric push rod 9 and the locking assembly 10 are approximately horizontal and located above the height slot 11 of the base 01. At this time, the base 01 and the backrest 04 can also be connected by the anti-detachment assembly 2 to prevent the base 01 and the backrest 04 from separating. When it needs to be unfolded, the backrest 04 is manually operated to rotate relative to the base 01. When the backrest 04 is rotated to the correct position, the shower chair is in its folded state. Figure 10 As shown, at this time, the middle sleeve 101 of the anti-slip component 2 contacts the arc-shaped surface of the lower hook 61 of the front and rear movable component 6, causing the lower hook 61 to move forward. At this time, the opening angle of the chair back 04 is usually at its maximum. After the chair back 04 rotates to its position, the electric push rod 9 is activated, and the linear push rod extends. During the rotation of the electric push rod 9 and the chair back 04 relative to the base 01, the locking component 10 at the end of the linear push rod moves backward into the height locking groove 11 of the base 01. At this time, the shower chair is in the following state: Figure 11 and Figure 12 As shown. When the locking assembly 10 at the end of the linear push rod is located in the height slot 11 of the base 01, the locking assembly 10 will not be able to move backward. At this time, the linear push rod of the electric push rod 9 continues to extend, and under the guidance of the lifting bracket 02, the chair seat 03 rises approximately vertically. At the same time, the chair back 04 and the electric push rod 9 rotate forward relative to the base 01 and the chair seat 03. When the linear push rod of the electric push rod 9 extends to a preset length (by preset motion parameters in the program or by setting a limit switch, etc.), the electric push rod 9 stops working. At this time, the state of the shower chair is as follows. Figure 13 As shown; at this time, since the pressing part of the seat 03 has separated from the front and rear stops 51 of the front and rear blocking assembly 5, the front and rear stops 51 return to the movement path of the locking assembly 10 under the action of the first elastic member 52. The front and rear stops 51 block the locking assembly 10 from moving forward, and at the same time, the height locking groove 11 and the left and right limiting groove 12 on the base 01 also prevent the locking assembly 10 from moving backward (the left and right limiting groove 12 also prevents the locking assembly 10 from moving left and right), so the locking assembly 10 is fixed.

[0090] When the shower chair is in Figure 13 In the unfolded state shown, when folding is required, activate the electric push rod 9 to retract its linear push rod. This folds the lifting bracket 02, and simultaneously lowers the seat 03 and backrest 04. Once lowered to a sufficient height, the shower chair will then be in the following position: Figure 11 and Figure 12As shown, the pressing member of the seat 03 abuts against the front and rear stops 51 of the front and rear blocking assembly 5 of the base 01. After the pressing member of the seat 03 abuts against the front and rear stops 51 of the front and rear blocking assembly 5 of the base 01, the front and rear stops 51 move away from the moving path of the locking assembly 10. At this time, the linear push rod of the electric push rod 9 continues to retract, and the backrest 04 and the electric push rod 9 rotate backward relative to the base 01. After rotating backward to the final position, the state of the shower chair is as follows. Figure 10 As shown, the electric push rod 9 stops working at this time. When the shower chair is in the following state... Figure 10 When manually rotating the chair back 04 forward, the chair back 04 and the electric push rod 9 will rotate forward (the size design ensures that the locking assembly 10 will not interfere with the height locking slot 11). After the chair back 04 and the electric push rod 9 have rotated forward into place, the shower chair will be in the following state: Figure 9 As shown.

[0091] The beneficial effects of the shower chair in Embodiment 1 of this utility model are as follows: When the shower chair is in the unfolded state, the height locking block 103 of the locking assembly 10 on the linear push rod of the electric push rod 9 is located in the height locking groove 11 of the base 01, so the seat 03 cannot continue to rise relative to the base 01. Under the action of the elastic member, the front and rear stops 51 are on the movement path of the front and rear limiting parts of the locking assembly 10 on the linear push rod of the electric push rod 9, so the linear push rod of the electric push rod 9 cannot move back and forth, ultimately making the linear push rod in the unfolded state unable to move forward and backward. The outer end of the rod is fixed to the base 01, and the front and rear stops 51 are movable without hindering the change from the unfolded state to the folded state; the rear end of the bottom of the base 01 (the end where the backrest 04 is located) is equipped with casters for easy movement; the seat 03 forms a self-supporting surface and the center of gravity is designed to achieve self-support; a headrest is provided, and the functional slot 81 for installing the headrest can also be used as a grip slot when moving; the anti-slip structure of the seat 03 and the base 01 has been improved; an anti-slip component 2 is provided to prevent the backrest 04 and the base 01 from separating, which is beneficial for storage and movement.
