[0034] The following will be combined with the accompanying drawings of specific embodiments of the present invention to clearly and completely describe the exemplary embodiments of the present invention. Unless otherwise defined, technical terms or scientific terms used in the present invention should be understood by people with ordinary skills in the field.
[0035] like Figure 1-Figure 5 As shown, the power-assisted toilet chair of this embodiment includes a seat cushion 1, a lifting support assembly, and a drive member. Two sets of lifting support assemblies are arranged oppositely on either side of the bottom surface of the seat cushion 1 and are fixedly connected by a connecting rod 102 and bolts. The lifting support assembly includes two oppositely arranged sliding plates 202, the top ends of the sliding plates 202 being fixedly connected to the bottom surface of the seat cushion 1. The drive member is used to drive the sliding plates 202 and the seat cushion 1 to move up and down along a curve. The bottom end of the drive member is hinged to the lower end of the lifting support assembly, and the output end of the drive member is hinged to the upper ends of the two sliding plates 202. The drive member drives the seat cushion 1 to move up and down together through the sliding plates 202, thereby providing stable support for the user when standing up, and assisting the user in transitioning from a sitting position to a standing position.
[0036] Furthermore, the number of the connecting rods 102 can be set according to actual conditions, and the positions of the connecting rods 102 should not affect user use.
[0037] Furthermore, the tops of the two sliding plates 202 are welded together via a top plate 2021 , and the top plate and the seat cushion 1 are connected via screws and nuts, thereby ensuring the connection stability between the sliding plates 202 and the seat cushion 1 .
[0038] Furthermore, a plurality of reinforcing plates are welded between the two sliding plates 202 to increase the structural stability between the two sliding plates 202 .
[0039] like Figure 3-Figure 5 As shown, the lifting support assembly also includes a grooved bottom plate 203, two support plates 201 and a plurality of guide rod groups. The lower ends of the two support plates 203 are fixed to the outer sides of the two wing plates of the grooved bottom plate 203 by bolts, and the upper ends of the two support plates 203 are fixed to the bottom of the connecting rod 102. The guide rod group is clamped between the two support plates 203; each guide rod group includes two left and right guide rod members 204, and the two sliding plates 202 are slidably clamped between the two guide rod members 204.
[0040] Furthermore, the number of guide rod groups can be adjusted according to actual conditions such as the size of the toilet power chair to ensure the movement stability of the sliding plate 202.
[0041] like Figure 4-Figure 5As shown, the guide rods 204 on the same side of the sliding plate 202 are arranged in a curve as a whole, thereby ensuring that the sliding plate 202 can move in a curve along the guide rods 204 .
[0042] Furthermore, the guide rod 204 can rotate around its own axis, thereby changing the friction between the sliding plate 202 and the guide rod 204 from sliding friction to rolling friction, which not only reduces the wear between the sliding plate 202 and the guide rod 204, but also improves the smoothness of the movement of the sliding plate 202.
[0043] Specifically, the guide rod 204 comprises a pin 2041, a sleeve 2042, and two bearings 2043. Furthermore, both support plates 201 are provided with a plurality of corresponding positioning holes. The pin 2041 is inserted into the positioning holes of the two support plates 201, and the sleeve 2042 is sleeved onto the pin 2041. The two bearings 2043 are sleeved onto the ends of the pin 2041 and contact the intermediate sleeve 2042. Preferably, these bearings are deep groove ball bearings.
[0044] In actual production, Figure 6 As shown, the two sliding plates 202 are respectively in contact with the outer rings of the two bearings 2042, and the sliding plates 202 and the outer rings of the bearings 2042 roll relative to each other. The rolling contact between the bearings 2042 of the guide rod 204 and the sliding plates 202 ensures the smooth movement of the sliding plates 202.
[0045] like Figure 4-Figure 5 As shown, the sliding plate 202 is arc-shaped, and the curvature of the sliding plate 202 is the same as the curvature of the entire guide rod 204 on the same side thereof, thereby improving the adaptability of the sliding plate 202 and the guide rod assembly (guide rod 204).
[0046] like Figure 3-Figure 5 As shown, the driving element is a telescopic cylinder 3, which is arranged between two support plates 201. The bottom of the telescopic cylinder 3 is hinged in the grooved bottom plate 203, and the push rod of the telescopic cylinder 3 is hinged to the upper parts of the two sliding plates 202. The telescopic cylinder 3 is extended and retracted, which drives the sliding plates 202 to move up and down along the curve, thereby driving the seat cushion 1 to move.
[0047] It should be understood that when a user stands up after using the toilet, the body will lean forward, and then the legs will exert force to achieve the standing action. The movement of the sliding plate 202 of the toilet power-assisted chair of the present invention is well adapted to the user's standing action, as follows:
[0048] like Figure 4As shown, the user sits on the seat cushion 1. When the user stands up, the telescopic cylinder 3 extends, and the push rod of the telescopic cylinder 3 drives the sliding plate 202 to move upward along the curve in the guide rod group, and drives the seat cushion 1 to rotate upward, thereby improving the adaptability of the sliding plate 202 (and the seat cushion 1) to the user's forward leaning and standing up action, thereby improving the user's comfort.
[0049] like Figure 1-Figure 5 As shown, armrests 101 are fixed to both sides of the top surface of the seat cushion 1 by bolts.
[0050] like Figure 1-Figure 5 As shown, the lifting support assembly is covered with a shell 4, and the grooved bottom plate 203 is fixed to the bottom of the shell 4 by bolts. The web of the grooved bottom plate 203 is screwed with a support leg 401 extending from the bottom surface of the shell 4.
[0051] Furthermore, the armrest 101 is covered with a flexible material to ensure flexible contact between the user's arm and the armrest 101 .
[0052] Furthermore, the material used for the housing 4 is plastic.
[0053] Furthermore, there are multiple support legs 401, and the height of each support leg 401 can be adjusted individually, thereby ensuring the stable placement of the power-assisted toilet chair of the utility model. Preferably, the support legs 401 can be suction cups, which can be firmly attached to the ground to prevent the power-assisted toilet chair from shifting during use and the risk of the user falling.
[0054] Furthermore, the telescopic cylinder 3 of the present invention is electrically connected to an external controller, and the controller controls the telescopic cylinder 3 to move, thereby assisting the user to stand up.
[0055] Here's how it works:
[0056] S1. Figure 4 As shown, the user sits on the seat cushion 1 to use the toilet. After the user finishes using the toilet, the controller controls the telescopic cylinder 3 to extend.
[0057] S2. Figure 5 As shown, the telescopic cylinder 3 is extended, and its push rod pushes the sliding plate 202 and the seat cushion 1 to move upward along the shaft bearing 2042 in a curve, driving the user to move upward, thereby assisting the user to complete the standing action;
[0058] S3. After the user stands up, the controller controls the telescopic cylinder 3 to retract and recover for the next use.
[0059] It should be noted that when one element is expressed as “connected”, “coupled” or “connected” to another element, it may mean that they are directly connected, coupled or connected, but it should be understood that there may be intermediate elements between the two; that is, the positional relationship of direct connection and indirect connection is covered.
[0060] It should be noted that the use of "a" or "an" and similar words does not necessarily indicate a limitation of quantity. "Include" or "comprising" and similar words mean that the elements or objects preceding the word include the elements or objects listed after the word and their equivalents, but do not exclude other elements or objects.
[0061] It should be noted that terms such as "up", "down", "left" and "right" that indicate orientation or positional relationships are only used to indicate relative positional relationships. This is for the convenience of describing the present invention, and does not mean that the device or element must have a specific orientation, be constructed and operated in a specific orientation. When the absolute position of the object being described changes, the relative positional relationship may also change accordingly.
