Description

Technical Field

[0001] The present application relates to the technical field of remote control electrical appliances, and in particular to a remote control. Background Art

[0002] With the advancement of science and technology, most of the existing electrical appliances, such as televisions, air conditioners and fans, can be remotely controlled by equipping them with remote controls, enabling remote switching and function selection of electrical appliances, thereby improving the user experience.

[0003] The housing of a remote control may include an upper housing and a lower housing. The upper and lower housings are assembled together to form the housing portion of the remote control. The space between the upper and lower housings forms a mounting cavity for mounting other remote control components, such as buttons, batteries, and control panels. For such products, water and liquid ingress are common during user use. This can cause external liquids to enter the mounting cavity, short-circuiting components such as the control panel and battery, and ultimately damaging the product.

[0004] In related art, a keyhole is provided in the upper housing, with the button portion of the key accommodated within the hole. A certain gap exists between the button portion and the hole to facilitate user pressure. Support ribs are provided around the button portion to support the key body. External liquid may enter through the gap between the button portion and the hole. Because the support ribs are in hard contact with the key body, with a clearance fit between the two, this cannot prevent liquid from continuing to flow toward the edge of the key body. This could potentially cause liquid to flow toward components such as the control panel, resulting in product damage and customer complaints. Utility Model Content

[0005] The present application provides a remote control that can improve the waterproof performance of the button portion of the key, reduce the possibility of external liquid entering the installation cavity, and increase the product service life.

[0006] According to one aspect of the present application, the present application provides a remote controller, comprising:

[0007] An upper shell, wherein the upper shell is provided with a button hole;

[0008] A lower shell is mounted on the upper shell, with a mounting cavity formed between the lower shell and the upper shell;

[0009] Flexible buttons, including:

[0010] a body, the body being disposed in the mounting cavity;

[0011] a button portion protruding from the upper surface of the body and accommodated in the button hole;

[0012] A control panel is disposed in the mounting cavity, the control panel is located on the lower side of the body, and a button position corresponding to the button portion is provided on the control panel;

[0013] Among them, a protruding first support rib is provided on the side of the upper shell facing the main body, the first support rib corresponds to the position of the button hole, the first support rib is annular, the first support rib surrounds the button part and abuts against the upper surface of the main body, and the first support rib and the upper surface of the main body are interference fit.

[0014] The above technical features have at least the following technical effects and advantages:

[0015] By providing a protruding first support rib on the side of the upper shell facing the main body, the first support rib can be used to support the upper shell. The first support rib is annular and surrounds the button part therein, isolating the button part from other parts of the installation cavity. By pressing the first support rib against the main body, the first support rib and the main body can have an interference fit. Even if some liquid enters the bottom side of the button part from the button hole, the first support rib and the main body are pressed against each other, making it almost difficult for the liquid to pass through the area between the first support rib and the main body. Thus, the external liquid can be trapped in the button hole and wait for it to evaporate naturally, preventing the liquid from flowing into the installation cavity, thereby improving the waterproof performance of the remote control and further improving the service life of the remote control.

[0016] In an exemplary embodiment of the present disclosure, a second support rib is further protruded from a side of the upper shell facing the main body, the second support rib is annular to surround all button portions of the main body, the second support rib abuts against the edge of the upper surface of the main body, and the second support rib and the edge of the upper surface of the main body are interference fit.

[0017] The above technical features have at least the following technical effects and advantages:

[0018] By setting a second support rib, the second support rib is pressed against the edge of the main body, and the second support rib and the edge of the main body form an interference fit, preventing liquid from flowing from the bottom of the second support rib into the edge of the main body, thereby cooperating with the first support rib to further improve the waterproof performance of the remote control.

[0019] In an exemplary embodiment of the present disclosure, a first water retaining rib is provided along the contour of the main body edge, the first water retaining rib protrudes from the upper surface of the main body, and the first water retaining rib is provided around the second supporting rib.

[0020] The above technical features have at least the following technical effects and advantages:

[0021] By setting the first water retaining rib, the first water retaining rib is protruded to have a certain height, thereby forming a "high wall" so that if water leaks from the second supporting rib, it can be blocked by the first water retaining rib to isolate the liquid from leaking to the control panel as much as possible.

[0022] In an exemplary embodiment of the present disclosure, the button hole includes a first button hole and a second button hole, the button portion includes a first button portion and a second button portion, and two first supporting ribs are provided, one corresponding to the first button hole and the other corresponding to the second button hole;

[0023] A separation rib is further provided on a side of the upper shell facing the main body. The separation rib abuts against the main body and is located between the two first support ribs.

[0024] The above technical features have at least the following technical effects and advantages:

[0025] By providing a first button portion and a second button portion, the remote control can be used in a wider range of ways, providing multiple remote control functions and enhancing the user experience. Accordingly, two first support ribs are provided to correspond to the first and second button holes, thereby surrounding the first and second button portions and improving the waterproof performance of the first and second button portions. Furthermore, a separator rib is provided to connect the two first support ribs, separating the area between the main body and the upper shell, excluding the support ribs. Even if a small amount of liquid leaks from the first support ribs, the separator ribs will block its flow and prevent it from flowing directly to the edge of the main body, thereby improving the waterproof performance of the remote control.

[0026] In an exemplary embodiment of the present disclosure, an electronic component is provided on the control board, and a protrusion is provided on a side of the body facing away from the control board. The protrusion forms a receiving groove on a side of the body facing the control board. The upper end of the receiving groove is closed, and the electronic component is accommodated in the receiving groove.

[0027] The above technical features have at least the following technical effects and advantages:

[0028] By providing a protrusion to form a receiving groove, the electronic components on the control board are covered therein to prevent external liquid from directly entering the control board through the electronic components. This improves the waterproof performance of the remote control without affecting the setting of the electronic components.

[0029] In an exemplary embodiment of the present disclosure, the remote control further includes a first sealing member, the first sealing member extending along an edge contour of the upper shell, and the first sealing member being clamped at a connection between an edge of the upper shell and an edge of the lower shell.

[0030] The above technical features have at least the following technical effects and advantages:

[0031] By setting the first seal, the first seal can be used to seal the connection between the upper shell and the lower shell, preventing liquid from leaking into the installation cavity from the gap between the two, thereby improving the waterproof performance of the connection between the upper shell and the lower shell.

[0032] In an exemplary embodiment of the present disclosure, a second water retaining rib is protruded from a surface of the upper shell facing the lower shell, the second water retaining rib extends along the edge contour of the lower shell, and the second water retaining rib is tightly pressed against the inner side surface of the lower shell.

[0033] The above technical features have at least the following technical effects and advantages:

[0034] By setting a second water retaining rib, the second water retaining rib is pressed against the inner side surface of the lower shell, thereby cooperating with the first seal to form two waterproof barriers for the gap between the lower shell and the upper shell, ensuring that liquid cannot leak into the installation cavity from the gap at the connection between the upper shell and the lower shell, thereby improving the waterproofness of the remote control.

[0035] In an exemplary embodiment of the present disclosure, the remote controller further includes a battery cover;

[0036] A battery compartment is provided in the lower housing for accommodating batteries. A compartment opening is provided on the lower housing corresponding to the battery compartment, and the battery cover is engaged with the compartment opening to open and close the battery compartment.

[0037] A second sealing member is provided around the circumference of the battery compartment. The second sealing member is arranged around the edge of the upper surface of the battery compartment, and the battery cover is tightly pressed against the second sealing member.

[0038] The above technical features have at least the following technical effects and advantages:

[0039] By providing a second seal, when the battery cover is pressed against the second seal, the sealing effect of the second seal can be utilized to prevent external liquid from leaking into the battery compartment through the gap between the battery cover and the battery compartment, thereby preventing the battery from short-circuiting, thereby improving the waterproof performance of the battery compartment.

[0040] In an exemplary embodiment of the present disclosure, a hollow fixing cavity is formed on a side of the lower shell facing the upper shell, a hook portion is provided in the fixing cavity, and a locking hole communicating with the battery compartment and a formed hole communicating with the interior of the mounting cavity are provided on the fixing cavity;

[0041] A buckle portion is provided at one end of the battery cover, and the buckle portion extends into the fixing cavity through the buckle hole and is buckled onto the hook portion, so that the battery cover can be detachably mounted at the compartment opening;

[0042] The remote controller further includes a water blocking cover, which is disposed in the installation cavity and covers the forming hole to seal the forming hole.

[0043] The above technical features have at least the following technical effects and advantages:

[0044] The buckle and hook sections facilitate battery installation and removal without changing the normal battery replacement process. A water-blocking cap is also provided to cover the molded hole, preventing external liquid from entering the installation cavity through the molded hole, thereby improving the waterproof performance of the fixing cavity.

[0045] In an exemplary embodiment of the present disclosure, the water shutoff cover is connected to the lower shell;

[0046] One end of the fixed cavity where the forming hole is set is set as a forming end, and a third sealing member is provided on the water blocking cover. The third sealing member extends along the edge contour of the forming end, and the end of the forming end is tightly pressed against the third sealing member.

[0047] The above technical features have at least the following technical effects and advantages:

[0048] By connecting the water shutoff cover to the lower housing, the position of the water shutoff cover can be easily controlled, ensuring it maintains a tight fit against the opening of the molded hole. Furthermore, by providing a third sealing member, the molded end can be pressed against the third sealing member, and slight deformation of the third sealing member can be utilized to achieve a sealing effect, preventing liquid from flowing into the installation cavity through the gap between the molded hole and the water shutoff cover.

[0049] Beneficial effects:

[0050] In the present application, a protruding first support rib is provided on the side of the upper shell facing the main body, and the first support rib can be used to support the upper shell. The first support rib is annular, surrounding the button part therein, so that the button part is isolated from other parts of the installation cavity. And by making the first support rib press against the main body, the first support rib and the main body can have an interference fit. Even if some liquid enters the bottom side of the button part from the button hole, it will be difficult for the liquid to pass through the area between the first support rib and the main body because the first support rib and the main body are pressed tightly. Thus, the external liquid can be trapped in the button hole and wait for it to evaporate naturally, preventing the liquid from flowing into the installation cavity, thereby improving the waterproof performance of the remote control and further improving the service life of the remote control.

DETAILED DESCRIPTION

[0065] In order to make the purpose and implementation of this application clearer, the exemplary implementation of this application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of this application. Obviously, the described exemplary embodiments are only part of the embodiments of this application, not all of the embodiments.

[0066] It should be noted that the brief descriptions of terms in this application are only for the purpose of facilitating the understanding of the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise specified, these terms should be understood according to their ordinary and usual meanings.

[0067] In the specification and claims of this application and the accompanying drawings, the terms "first," "second," "third," etc. are used to distinguish similar or similar objects or entities, and are not necessarily intended to limit a particular order or sequence, unless otherwise noted. It should be understood that the terms used in this manner are interchangeable under appropriate circumstances.

[0068] The terms "comprise," "comprises," and "having," and any variations thereof, are intended to cover but not exclude inclusion; for example, a product or device comprising a list of components is not necessarily limited to all the components expressly listed but may include other components not expressly listed or inherent to such product or device.

[0069] In related art, a keyhole is provided in the upper housing, and the button portion of the key is accommodated in the keyhole. A certain gap is provided between the button portion and the keyhole to facilitate the user's pressing of the button portion. Support ribs are provided around the upper housing to support the button portion, but external liquid may enter through the gap between the button portion and the keyhole. Because the support ribs are in hard contact with the key body and a clearance fit is used between the two, it is impossible to prevent liquid from continuing to flow toward the edge of the key body. This may cause liquid to flow to components such as the control panel, resulting in product damage and customer complaints. To address this issue, this embodiment specifically proposes a remote control.

[0070] For ease of understanding, the upper direction in this embodiment refers to the direction of the front side of the remote control, and the lower direction refers to the direction of the back side of the remote control.

[0071] See also Figures 1 to 3 This embodiment provides a remote controller that can be used to remotely control various electrical appliances to control the electrical appliances to perform corresponding operations, such as turning them on and off and selecting functions, etc., wherein the various electrical appliances may include televisions, air conditioners, fans, etc.

[0072] In some embodiments, the remote control may include an upper housing 1. The upper housing 1 is one of the housing components of the remote control. The upper housing 1 may be in the shape of an elongated plate as a whole, so that the remote control can form a slender plate structure, facilitating the arrangement of multiple buttons 32 representing different functions along the length of the remote control, thereby providing a better control experience for the user.

[0073] In some embodiments, the upper housing 1 may be provided with a button hole 11 , which may be a circular hole or a square hole, etc. The button hole 11 passes through the upper surface of the upper housing 1 .

[0074] In some embodiments, the remote control may further include a lower housing 2. The lower housing 2 is mounted on the upper housing 1 and is one of the components of the remote control housing. Together, the lower housing 2 and the upper housing 1 form the remote control housing. A mounting cavity may be formed between the lower housing 2 and the upper housing 1 to accommodate other components of the remote control, such as electronic components and the battery 6. The button hole 11 communicates with the mounting cavity.

[0075] It is understood that the upper housing 1 is located above the lower housing 2. The upper side of the upper housing 1 is the front side of the remote control, and the lower side of the lower housing 2 is the back side of the remote control. The lower housing 2 can cover the upper housing 1, or the lower housing 2 can be installed by snapping its edge onto the edge of the upper housing 1.

[0076] In some embodiments, the upper shell 1 and / or the lower shell 2 may be a semi-enclosed structure with one end open, so that during assembly, the open ends of the two are butted together to form an installation cavity having a certain space.

[0077] In this embodiment, the lower shell 2 can be the main part of the remote control housing, which is a semi-enclosed structure with one end open and a large space formed inside. The upper shell 1 is installed on the lower shell 2 to close the open end of the lower shell 2, thereby forming a closed installation cavity.

[0078] In some embodiments, the remote control may further include a flexible button 3. The flexible button 3 may be made of a flexible material, such as rubber, so as to have a certain degree of flexibility so that it can be pressed and can recover by itself after being pressed.

[0079] In some embodiments, the flexible button 3 may include a body 31. The body 31 is the main part of the flexible button 3 and is disposed in the installation cavity. The body 31 may be a plate-like structure so as to be flatly arranged in the installation cavity to fully utilize the space of the installation cavity.

[0080] In some embodiments, the flexible button 3 may further include a button portion 32. The button portion 32 protrudes from the upper surface of the body 31 and is accommodated in the button hole 11, so that the user can press the button portion 32 to control the remote control and issue different commands. The shape of the button portion 32 can be adapted to the shape of the button hole 11. For example, in this embodiment, the button hole 11 is a circular hole, and the button portion 32 is a cylinder. The diameter of the button portion 32 is smaller than the diameter of the button hole 11, so that the button portion 32 can be pressed and deformed. In order to provide a user experience, there may be a certain gap between the button portion 32 and the button hole 11 to facilitate the deformation and restoration of the button portion 32 by pressing.

[0081] Continue to see Figures 5 to 8 In some embodiments, the remote control may further include a control board 4. The control board 4 is the main control circuit board of the remote control, which is used to issue corresponding instructions according to the action of the button part 32 to control the electrical device to perform relevant operations. The control board 4 can be set in the installation cavity, and the control board 4 can be located on the lower side of the body 31, and can be in contact with the lower surface of the body 31 or not. A button position 41 corresponding to the button part 32 can be provided on the control board 4. When the button part 32 is pressed downward by the user, the button part 32 contacts the button position 41, so that the control board 4 generates a corresponding control signal, and generates a corresponding control instruction according to the control signal, and finally transmits the control instruction to the electrical device to remotely control the electrical device to perform corresponding operations.

[0082] In some embodiments, a first support rib 12 may be provided on the side of the upper housing 1 facing the body 31. The first support rib 12 may protrude from the side of the upper housing 1 facing the body 31 to provide a certain height. The first support rib 12 corresponds to the position of the button hole 11 and is annular. The first support rib 12 is arranged around the button portion 32, thereby enclosing the button portion 32 and isolating it from the rest of the mounting cavity.

[0083] In some embodiments, the first supporting rib 12 may be in the shape of a circular ring, a rectangular ring, or other special-shaped rings, as long as it can enclose the button portion 32 therein.

[0084] In this embodiment, the first support rib 12 can abut against the main body 31, so that the first support rib 12 and the upper surface of the main body 31 are interference fit, thereby surrounding the button part 32 while preventing the liquid entering from the button hole 11 from leaking from the bottom of the first support rib 12 to the outside of the first support rib 12, thereby preventing external liquid from entering the installation cavity and eventually flowing to the control board 4, causing a short circuit in the circuit on the control board 4, and improving the waterproof performance of the remote control.

[0085] In some embodiments, the flexible button 3 has a certain degree of flexibility, which in turn makes the body 31 also flexible. By pressing the first support rib 12 against the body 31, the first support rib 12 compresses the body 31 to slightly deform, so that the bottom of the first support rib 12 is embedded in the deformed part of the body 31, further improving the sealing performance and preventing liquid from leaking from the inside of the first support rib 12 to the outside.

[0086] In some embodiments, by providing the first supporting rib 12 , the upper shell 1 can also be supported to prevent the center of the upper shell 1 from collapsing.

[0087] In some embodiments, a second support rib 13 may be further provided on the side of the upper shell 1 facing the main body 31. The second support rib 13 may protrude from the side of the upper shell 1 facing the main body 31, so that the second support rib 13 has a certain height. The second support rib 13 abuts against the edge of the upper surface of the main body 31, so that the second support rib 13 and the edge of the upper surface of the main body 31 form an interference fit, thereby improving the airtightness of the edge of the main body 31. The second support rib 13 is annular to surround all the button portions 32 of the main body 31. The second support rib 13 forms a sealed structure at the edge of the main body 31, and cooperates with the first support rib 12 to further improve the airtightness between the main body 31 and the installation cavity. Even if a very small amount of liquid leaks from the first support rib 12, it will be blocked by the second support rib 13, so that it cannot pass through the second support rib 13 and enter the installation cavity from the edge of the main body 31.

[0088] It should be noted that if the body 31 is a rectangular plate-like structure, the second support ribs 13 form a rectangular ring structure along the edge of the body 31. If the body 31 is a circular plate-like structure, the second support ribs 13 form a circular ring structure along the edge of the body 31. The second support ribs 13 can also support the edge of the upper shell 1, preventing the upper shell 1 from becoming uneven due to pressure from the user, thereby improving the structural strength of the upper shell 1.

[0089] In some embodiments, a first water retaining rib 33 may be provided along the edge of the body 31 along its own contour. The first water retaining rib 33 may protrude from the upper surface of the body 31, so that the first water retaining rib 33 has a certain height. Since the first water retaining rib 33 is formed along the contour of the edge of the body 31, the first water retaining rib 33 has the same shape as the contour of the edge of the body 31 and corresponds to the shape of the second support rib 13.

[0090] In some embodiments, the first water retaining rib 33 is disposed around the second support rib 13 and cooperates with the second support rib 13 so that any water leaking from the second support rib 13 is blocked by the first water retaining rib 33. The height of the first water retaining rib 33 forms a "high wall" to minimize liquid leakage onto the control panel 4. To further enhance the isolation effect, the inner side of the first water retaining rib 33 can be in close contact with the second support rib 13, making it more difficult for liquid to pass through the first water retaining rib 33.

[0091] In some embodiments, the button hole 11 may include a first button hole and a second button hole, and the first button hole and the second button hole are spaced apart. The button portion 32 may include a first button portion and a second button portion, and the first button portion and the second button portion are respectively accommodated in the first button hole and the second button hole. Two first support ribs 12 may be provided, corresponding to the first button hole and the second button hole, respectively, to surround the first button portion and the second button portion, respectively. The first button portion and the second button portion may represent different remote control functions of the remote control, and the two are provided at different positions on the body 31.

[0092] In some embodiments, a partition rib 14 may be provided on the side of the upper housing 1 facing the body 31. The partition rib 14 protrudes from the side of the upper housing 1 facing the body 31, providing a certain height. The partition rib 14 abuts against the body 31, creating an interference fit with the upper surface of the body 31 to prevent liquid from leaking out from the bottom of the partition rib 14.

[0093] In some embodiments, the separating rib 14 is located between the two first supporting ribs 12, and can separate the area between the main body 31 and the upper shell 1 except for the supporting ribs 12. Even if a small amount of liquid leaks from the first supporting rib 12, it can be blocked by the separating rib 14 and will not flow directly to the edge of the main body 31, thereby improving the waterproof performance of the remote control.

[0094] Furthermore, the button hole 11 can also include a third button hole, a fourth button hole to an Nth button hole, and accordingly, the button part 32 can also include a third button part, a fourth button part to an Nth button part, and the first support rib 12 can also have N pieces, and be arranged one-to-one corresponding to the first to Nth button holes, so that the remote control has more remote control functions, such as making the first to Nth button parts correspond to on, off, mode selection, standby and digital functions respectively, so that the remote control can issue corresponding control instructions according to the different button parts 32 pressed by the user, so as to remotely control the electrical equipment to perform different operations.

[0095] Accordingly, multiple partition ribs 14 can be provided, and a partition rib 14 can be connected between adjacent first support ribs 12, so as to cooperate with the first support rib 12 and the second support rib 13 to separate the area between the main body 31 and the upper shell 1 into multiple independent partition chambers 15. Even if a small amount of liquid leaks from the first support rib 12, it will enter the partition chamber 15 adjacent to the first support rib 12 for storage, and will not flow directly to the edge of the main body 31. The liquid will slowly evaporate and disappear in the partition chamber 15, thereby preventing it from entering the control board 4, thereby improving the waterproof performance of the remote control.

[0096] In some embodiments, multiple separation ribs 14 are provided to support the upper shell 1 in various directions, thereby further improving the structural strength of the upper shell 1 .

[0097] It should be noted that the partition cavity 15 can be formed by the outer side wall of the adjacent first support rib 12 and the partition rib 14, or by the outer side wall of the first support rib 12 and the inner side wall of the second support rib 13 and the partition rib 14.

[0098] In some embodiments, the control board 4 may be provided with an electronic component 42. The electronic component 42 may be a capacitor arranged on the control board 4 or a wire arranged on the control board 4 and connected to the battery 6. Due to the circuit layout, it needs to be arranged on the side of the control board 4 facing the main body 31, so that the electronic component 42 will protrude from the side of the control board 4 facing the main body 31. A corresponding space needs to be set on the main body 31 to avoid the electronic component 42, but this may cause the liquid to flow directly from this area to the control board 4, causing a short circuit in the control board 4.

[0099] Therefore, in this embodiment, a protrusion 34 can be provided on the side of the body 31 facing away from the control board 4. The protrusion 34 protrudes from the side of the body 31 facing away from the control board 4, so that the protrusion 34 has a certain height. The protrusion 34 forms a receiving groove on the side of the body 31 facing the control board 4. The upper end of the receiving groove is sealed and isolated from the outside of the protrusion 34. The electronic component 42 can be accommodated in the receiving groove, thereby protecting the electronic component 42 while surrounding it, preventing external liquid from entering the electronic component 42 through the protrusion 34.

[0100] In some embodiments, the protrusion 34 can be integrally formed on the surface of the body 31 facing away from the control panel 4, thereby eliminating any gap between the protrusion 34 and the body 31 and completely isolating liquid from entering through the gap between the protrusion 34 and the body 31. The protrusion 34 can be located within the partition cavity 15, and the outer wall of the protrusion 34 can conform to the outer wall of the first support rib 12, thereby reducing the empty space in the partition cavity 15 and making it more difficult for liquid to flow from the partition cavity 15 to the second support rib 13, thereby improving waterproof performance.

[0101] In some embodiments, the remote control may further include a first sealing member 5. The first sealing member may extend along the edge contour of the upper housing 1, so that the first sealing member 5 is an annular structure. The first sealing member 5 may be a sealing ring made of waterproof foam and have certain waterproof sealing properties.

[0102] During installation, the first seal 5 can be clamped between the edges of the upper and lower housings 1 and 2, sealing the connection between them and preventing liquid from leaking into the installation cavity through the gap between them, thereby enhancing the remote control's overall waterproofness. A clamping groove can be provided on the edge wall of the lower housing 2, housing the first seal 5. The edge of the upper housing 1 presses against the first seal 5, achieving a sealing effect through slight deformation of the first seal 5. Alternatively, the clamping groove can be provided on the edge of the upper housing 1.

[0103] In some embodiments, a second water retaining rib 16 may be provided on the side of the upper shell 1 facing the lower shell 2. The second water retaining rib 16 protrudes from the side of the upper shell 1 facing the lower shell 2, so that the second water retaining rib 16 has a certain height. The second water retaining rib 16 may extend along the edge contour of the lower shell 2 to match the edge shape of the lower shell 2. During installation, the second water retaining rib 16 presses against the inner side of the lower shell 2, thereby cooperating with the first sealing member 5 to form two waterproof barriers for the gap between the lower shell 2 and the upper shell 1, ensuring that liquid cannot leak into the installation cavity through the gap at the connection between the upper shell 1 and the lower shell 2, thereby improving the waterproof performance of the remote control.

[0104] Continue to see Figure 4 ,as well as Figures 9 to 12 In some embodiments, the remote control may further include a battery cover 7. A battery compartment 21 is provided within the lower housing 2 for accommodating the battery 6, which is used to power the control board 4. A hatch is provided on the lower housing 2 corresponding to the battery compartment 21, and the battery cover 7 is engaged with the hatch to open and close the battery compartment 21. When installing or removing the battery 6, the battery cover 7 is removed from the hatch to expose the battery compartment 21, allowing the battery 6 to be installed in the battery compartment 21. Finally, the battery cover 7 is reattached to the hatch to seal the battery compartment 21.

[0105] In this embodiment, the battery compartment 21 can be a rectangular cavity, the upper end of the battery compartment 21 is open, the compartment opening on the lower shell 2 is opened corresponding to the upper end opening of the battery compartment 21, and the battery cover 7 matches the shape and size of the compartment opening so that it can just cover the compartment opening.

[0106] In some embodiments, a second sealing member 22 may be provided around the perimeter of the battery compartment 21. This second sealing member 22, which can be a sealing ring made of waterproof foam and possessing a certain degree of waterproof sealing properties, is disposed around the edge of the battery compartment's upper surface. When the battery cover 7 is installed, it rests firmly against the second sealing member 22, thereby slightly deforming the second sealing member 22 to achieve a sealing effect, preventing external liquid from flowing into the battery compartment 21 through the gap between the battery cover 7 and the compartment opening.

[0107] In some embodiments, a fixing cavity 23 is formed on the side of the lower shell 2 facing the upper shell 1. The fixing cavity 23 is hollow inside and can be formed integrally with the lower shell 2. A hook portion 25 can be provided in the fixing cavity 23, and a latch hole 24 communicating with the battery compartment 21 is provided on the fixing cavity 23. A buckle portion 71 can be provided at one end of the battery cover 7, and the buckle portion 71 can be fastened with the hook portion 25. When installing the battery cover 7, the buckle portion 71 of the battery cover 7 can be extended into the fixing cavity 23 through the latch hole 24 and fastened to the hook portion 25, thereby locking the battery cover 7 to the lower shell 2. When the battery cover 7 needs to be removed, the buckle portion 71 can be disengaged from the hook portion 25 with a little force, so that the battery cover 7 can be smoothly removed from the battery compartment 21, thereby realizing the detachable installation of the battery cover 7 at the compartment opening.

[0108] In some embodiments, the fixing cavity 23 can be set at the front end of the battery compartment 21, and the card hole 24 can be opened on the side wall where the fixing cavity 23 and the battery compartment 21 are connected, so that it is convenient to push and pull the battery cover 7 back and forth to facilitate the installation and removal of the battery cover 7.

[0109] In some embodiments, the fixing cavity 23 is further provided with a forming hole 26 that communicates with the interior of the mounting cavity. The forming hole 26 can be provided on the side wall of the fixing cavity 23 facing the upper housing 1. By providing the forming hole 26, the fixing cavity 23 structure can be demolded together when the lower housing 2 is formed, thereby simplifying the manufacturing process of the lower housing 2.

[0110] In this embodiment, the forming hole 26 needs to be a through hole due to the manufacturing process, resulting in communication with the installation cavity. After the lower shell 2 and the upper shell 1 are assembled, a small amount of liquid entering the battery compartment 21 may enter the forming hole 26 through the card hole 24, and then enter the interior of the installation cavity through the forming hole 26, thereby causing a short circuit in the control board 4.

[0111] Therefore, the remote control may further include a water blocking cover 8. The water blocking cover 8 may be disposed in the mounting cavity to cover the forming hole 26, thereby blocking the forming hole 26 and preventing liquid from flowing into the mounting cavity through the forming hole 26, thereby improving the waterproof performance of the remote control.

[0112] In some embodiments, the water blocking cover 8 may be a plate-shaped structure, the surface size of which should be larger than the opening size of the forming hole 26 so as to be able to block the forming hole 26 .

[0113] In some embodiments, the water shutoff cover 8 can be connected to the lower shell 2 to facilitate installation of the water shutoff cover 8. Accordingly, a connecting post 83 can be provided on the side of the lower shell 2 facing the upper shell 1. One end of the water shutoff cover 8 can be screwed to the connecting post 83 via a screw 82, thereby conveniently fixing the water shutoff cover 8 and making the water shutoff cover 8 more tightly against the formed hole 26, thereby improving the sealing between the water shutoff cover 8 and the formed hole 26.

[0114] In some embodiments, the water shutoff cover 8 may be provided with a third sealing member 81. For ease of description, the end of the fixed cavity 23 where the molded hole 26 is located is designated as the molded end. The third sealing member 81 extends along the contour of the molded end to surround the opening of the molded hole 26. The third sealing member 81 may be a sealing ring made of waterproof foam, providing certain waterproof sealing properties. The end of the molded end abuts against the third sealing member 81, and slight deformation of the third sealing member 81 creates a sealing effect, preventing liquid from flowing into the installation cavity through the gap between the molded hole 26 and the water shutoff cover 8.

[0115] In some embodiments, a groove can be provided on the side of the water blocking cover 8 facing the forming hole 26, and the third sealing member 81 can be arranged in the groove to fix and limit the third sealing member 81, so that when the end of the forming end is pressed against the third sealing member 81, the two are pressed against each other without shifting, and the sealing is better.

[0116] In summary, in this embodiment, by providing a first support rib 12 surrounding the button portion 32 on the surface of the upper housing 1 facing the lower housing 2, the first support rib 12 is tightly pressed against the body 31, thereby improving the waterproof performance of the button portion 32. Furthermore, the second support rib 13, the first water-retaining rib 33, and the separating rib 14 cooperate to form multiple waterproof walls, preventing the possibility of external liquid leaking through the button hole 11 to the edge of the body 31.

[0117] At the same time, by arranging a first seal 5 at the connection between the upper shell 1 and the lower shell 2, the waterproof performance of the connection between the upper shell 1 and the lower shell 2 is improved. Combined with the second water retaining rib 16, it is possible to prevent external liquid from entering the installation cavity through the connection between the upper shell 1 and the lower shell 2.

[0118] Furthermore, by providing a second sealing member 22 at the battery compartment 21, the waterproof performance of the battery compartment 21 can be improved. A water-blocking cap 8 is provided at the molded hole 26, and a third sealing member 81 is used to seal the opening of the molded hole 26, preventing external liquid from entering the installation cavity through the molded hole 26. Without changing the structure of the battery compartment 21 or the installation method of the battery 6, the waterproof performance of the battery compartment 21 is improved. This, combined with the aforementioned waterproof measures, improves the overall waterproof performance of the remote control, enabling the remote control to achieve a waterproof rating of IPX3 or above.
