For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0036] For devices such as wheelchairs and bathing chairs, if they are set up conventionally, some operation buttons are set on the chair body so that users can control the wheelchair or bathing chair based on the buttons. However, the buttons set on the chair body are relatively inconvenient to operate. Therefore, a hand controller has emerged, which is separated from the chair body to facilitate the operation of the wheelchair or bathing chair by the user.

[0037] In order to enable the hand controller to better adapt to more environments, the hand controller needs to have a certain degree of waterproofness. Based on this, the embodiments of the present application provide a controller 10, which can have good waterproofness and thus improve the use safety of the controller 10. The controller 10 provided by the present application will be introduced below through some embodiments.

[0038] Figure 1 It is a schematic structural diagram of the controller 10 provided by the embodiments of the present application. As Figure 1 shown, the controller 10 may include a housing 100 and a button assembly 200.

[0039] The button assembly 200 is installed on the housing 100. Exemplarily, it can be referred to Figure 3 shown that an installation position 111 may be provided on the housing 100, and the shape of the installation position 111 matches the shape of the button assembly 200. The button assembly 200 is installed at the installation position 111.

[0040] A first sealing structure may be provided at the edge of the installation position 111, and a second sealing structure is provided at the edge of the button assembly 200. The shapes of the first sealing structure and the second sealing structure may fit each other.

[0041] In this embodiment, the first sealing structure of the installation position 111 cooperates with the second sealing structure of the button assembly 200 to seal the button assembly 200 and install it at the installation position 111.

[0042] Optionally, when the first sealing structure and the second sealing structure are installed in cooperation, the first sealing structure and the second sealing structure may be in interference fit, so that the first sealing structure and the second sealing structure are mutually extruded, so that the first sealing structure and the second sealing structure can better form a sealing structure, reducing the probability of water, steam, etc. entering the inside of the controller 10 from the edges of the installation position 111 and the button assembly 200.

[0043] Through the above structure, the sealing performance of the controller 10 can be improved, the use safety of the controller 10 can be improved, and the controller 10 can better meet the use requirements in more scenarios.

[0044] In an optional embodiment, the first sealing structure is a first groove 1112 provided at the edge of the installation position 111; the second sealing structure is a first protrusion 210 provided at the edge of the button assembly 200 and fitting with the first groove 1112; wherein, when the button assembly 200 is installed on the housing 100, the first protrusion 210 is embedded in the first groove 1112.

[0045] Specifically, it can be referred to Figure 2 and Figure 3As shown, the first groove 1112 can be provided at the edge of the installation position 111 to form an annular groove. The first protrusion 210 can be provided along the edge of the button assembly 200 to form an annular protrusion. The height of the first protrusion 210 can be not greater than the depth of the first groove 1112, and the width of the first protrusion 210 can be not less than the width of the groove of the first groove 1112.

[0046] Optionally, the material of the button assembly 200 can be an elastic material, and the material of the first protrusion 210 can also be an elastic material. The width of the first protrusion 210 can be greater than the width of the groove of the first groove 1112, so that the first protrusion 210 and the first groove 1112 can achieve an interference fit. The first protrusion 210 can be relatively more tightly inserted into the first groove 1112.

[0047] Exemplarily, the material of the button assembly 200 can be an elastic material such as silicone or rubber.

[0048] In another embodiment, the first sealing structure can also be a protrusion structure provided at the edge of the installation position 111, and the second sealing structure is a groove structure provided at the edge of the button assembly 200 and capable of fitting with the protrusion structure at the edge of the installation position 111. When the installation position 111 and the button assembly 200 are assembled, the protrusion structure at the edge of the installation position 111 is embedded in the groove structure at the edge of the button assembly 200.

[0049] The protrusion structure at the edge of the installation position 111 can be provided at the edge of the installation position 111 to form an annular protrusion. The groove structure at the edge of the button assembly 200 can be provided along the edge of the button assembly 200 to form an annular groove. The depth of the groove structure at the edge of the button assembly 200 can be greater than or equal to the height of the protrusion structure at the edge of the installation position 111, and the width of the groove of the groove structure at the edge of the button assembly 200 can be not greater than the width of the protrusion structure at the edge of the installation position 111.

[0050] Optionally, the material of the protrusion structure at the edge of the installation position 111 can be an elastic material, and the width of the protrusion structure at the edge of the installation position 111 can be greater than the width of the groove of the groove structure at the edge of the button assembly 200, so that the groove structure at the edge of the button assembly 200 and the protrusion structure at the edge of the installation position 111 can achieve an interference fit. The groove structure at the edge of the button assembly 200 can be relatively more tightly inserted into the protrusion structure at the edge of the installation position 111.

[0051] With the above structure, while enabling the sealed installation of the installation position 111 and the button assembly 200, it is also possible to achieve positioning through the groove and protrusion structure when the button assembly 200 is installed on the installation position 111, making the installation of the button assembly 200 and the installation position 111 more accurate. Further, due to the cooperation of the protrusion structure and the groove structure between the installation position 111 and the button assembly 200, the relative position of the installation position 111 and the button assembly 200 is also more stable.

[0052] To further improve the sealing performance of the controller 10, the controller 10 may further include a first sealing element disposed in the first groove 1112.

[0053] Exemplarily, the first sealing element may be a sealing strip disposed at the junction of the first groove 1112 and the second protrusion 221, for blocking the gap formed after the installation of the first groove 1112 and the second protrusion 221.

[0054] Exemplarily, when the button assembly 200 is installed on the housing 100, the first protrusion 210 is embedded in the first groove 1112 and forms an extrusion on the first sealing element.

[0055] Optionally, the first sealing element is sealing glue.

[0056] Exemplarily, when installing the button assembly 200, glue for sealing can be filled in the first groove 1112 to form the above-mentioned sealing glue.

[0057] In some cases, a plurality of buttons 220 may be provided on one controller 10 to implement different control operations. In this embodiment, the button assembly 200 may include a plurality of buttons 220.

[0058] Based on different actual requirements, the number of buttons 220 included in the button assembly 200 is also different. Taking the controller 10 used on a wheelchair as an example, the button assembly 200 may have a switch button 220, a forward button 220, a backward button 220, a lock button 220, etc. Taking the controller 10 used on a bathing chair as an example, the button assembly 200 may have a switch button 220, a forward button 220, a backward button 220, a lock button 220, a raise button 220, a lower button 220, etc.

[0059] A plurality of button installation positions 1111 may also be provided at the installation position 111 on the housing 100, and the number of buttons 220 is the same as the number of button installation positions 1111. The shapes of each button installation position 1111 also fit the shapes of each button 220.

[0060] In Figure 2In the illustrated example, three buttons 220 are shown in the figure. Correspondingly, three button mounting positions 1111 that fit the shapes of the three buttons 220 are also provided at the mounting position 111.

[0061] A third sealing structure may be provided at the edge of each button mounting position 1111, and a fourth sealing structure is provided at the edge of each button 220. The third sealing structure and the fourth sealing structure cooperate to seal the button 220 and mount it in the corresponding button mounting position 1111.

[0062] Optionally, the third sealing structure may be a second groove 1113 provided at the edge of each button mounting position 1111; the fourth sealing structure may be a second protrusion 221 provided at the edge of each button 220. Among them, the second protrusion 221 of each button 220 fits with the second groove 1113 at the edge of the corresponding button mounting position 1111.

[0063] The second protrusion 221 may be embedded in the second groove 1113 to form a sealed installation.

[0064] Exemplarily, the height of the second protrusion 221 may not be greater than the depth of the second groove 1113, and the width of the second protrusion 221 may not be less than the width of the groove of the second groove 1113.

[0065] If the material of the second protrusion 221 may be an elastic material, the width of the second protrusion 221 may be greater than the width of the second groove 1113. When the button assembly 200 is installed at the mounting position 111, the second protrusion 221 structure may be in interference fit with the second groove 1113, so that the second protrusion 221 and the second groove 1113 can better achieve the sealing effect.

[0066] Optionally, the third sealing structure may be a protrusion structure provided at the edge of each button mounting position 1111; the fourth sealing structure may be a groove structure provided at the edge of each button 220.

[0067] The protrusion structure at the edge of the button mounting position 1111 may be embedded in the groove structure at the edge of the button 220 to form a sealed installation.

[0068] In order to achieve a better sealing effect, a second sealing element is provided at the third sealing structure or the fourth sealing structure.

[0069] Among them, when the button 220 is installed in the button mounting position 1111, the second sealing element is used to block the connection between the third sealing structure and the fourth sealing structure.

[0070] Exemplarily, the second sealing element may be a sealing strip, and the sealing strip may be pasted at the connection between the third sealing structure and the fourth sealing structure.

[0071] The fourth sealing structure or the third sealing structure exerts extrusion on the second sealing element.

[0072] In this embodiment, the button 220 and the button mounting position 1111 can also be matched through a groove structure and a protrusion structure. The second sealing element can be embedded in the groove structure therein. When the button 220 is installed in the button mounting position 1111, the third sealing structure or the fourth sealing structure can exert extrusion on the second sealing element to form a sealed installation of the button 220 and the button mounting position 1111.

[0073] Optionally, the second sealing element can be sealing glue.

[0074] Exemplarily, when installing the button assembly 200, sealing glue can be filled in the groove structure of the third sealing structure or the fourth sealing structure to form the above-mentioned sealing glue.

[0075] By forming a seal for the installation of each button 220 and the housing 100, the sealing effect of the controller 10 can be better, and further the use safety of the controller 10 is improved.

[0076] The controller 10 can be a wireless controller 10 or a wired controller 10. In order to make the sealing effect of the controller 10 better, for the wired controller 10, sealing treatment can also be performed at the online connection.

[0078] Optionally, a third sealing element is provided at the wire outlet 130. The third sealing element can include sealing glue filled in the gap between the external wire 20 and the wire outlet 130.

[0079] Exemplarily, when connecting the external wire 20, glue can be filled at the wire outlet 130 so that the glue fills the gap between the wire outlet 130 and the external wire 20 to form the seal of the wire outlet 130.

[0080] In this embodiment, the housing 100 of the controller 10 can include a first housing 110 and a second housing 120. The first housing 110 and the second housing 120 can be closed to form an accommodation space.

[0081] In this embodiment, the mounting position 111 is provided on the first housing 110, and a battery accommodation area 121 is provided in the second housing 120.

[0082] Exemplarily, a plurality of through holes may be provided on the first housing 110, and the plurality of through holes may form a button mounting position 1111 for mounting the button 220. When the button 220 is mounted on the first housing 110, the pressing area of each button 220 protrudes from the surface of the first housing 110.

[0083] The battery 400 of the controller 10 may be provided with a battery accommodation area 121 in the second housing 120, which can relatively limit the battery 400 of the controller 10 and reduce the wear caused by the shaking of the battery 400 in the housing 100.
