Description

Technical Field

[0001] This application relates to the technical field of remote controls, and more specifically, to a remote control and electronic device component. Background Technology

[0002] Currently, the function keys of toggle switches in products on the market mainly rely on the on / off functions of the electronic toggle switch components themselves.

[0003] The surface-mount packaging of electronic switches has a relatively large tolerance, requiring a significant clearance in the structure, which affects the product's appearance. Furthermore, after assembly, it can easily cause jamming when the switch is toggled. Additionally, after a period of use, the thrust of the electronic switch components gradually decreases, leading to problems such as false triggering, poor contact, incomplete switch actuation, and reduced tactile feedback, making it difficult to meet customer requirements. In existing technologies, the thrust of electronic switches is generally constant during actuation, which fails to provide a proper buffered feel and results in a subpar user experience. Summary of the Invention

[0004] This application provides a remote control and electronic device assembly to solve the problem that in the prior art, the pushing force is generally constant during the actuation of electronic switches, which cannot meet the requirements for a buffered feel.

[0005] This application provides a remote controller, comprising: a housing having a receiving space and a switch clearance portion communicating with the receiving space and the outside of the housing; a switch assembly including a sliding structure and a fixed structure, the fixed structure being fixed within the receiving space, the sliding structure being at least partially disposed within the receiving space and corresponding to the switch clearance portion, the sliding structure and the fixed structure having mutually cooperating protrusion-contact locking portions; and a circuit assembly disposed within the receiving space; the sliding structure having a first position abutting against the circuit assembly and a second position disengaging from the circuit assembly, wherein when the sliding structure is in the first position and the second position, both the sliding structure and the fixed structure are engaged by the protrusion-contact locking portions.

[0006] Furthermore, the sliding structure includes a sliding plate, and the convex and concave locking part includes a first groove, a second groove, and a protrusion. The first groove and the second groove are located on the side of the sliding plate facing the fixed structure, and the protrusion is located on the side of the fixed structure facing the sliding plate.

[0007] Furthermore, the fixed structure includes a fixed plate and an elastic cantilever. The fixed plate has a central hollow and is fixedly connected to the housing. The first end of the elastic cantilever is connected to the side wall of the fixed plate, and the second end of the elastic cantilever is located in the central hollow. A protrusion is located on the side of the second end of the elastic cantilever facing the sliding plate.

[0008] Furthermore, the protrusion has an outer arc-shaped contour, while the first and second grooves both have inner arc-shaped contours.

[0009] Furthermore, the housing includes a first housing and a second housing that covers the first housing, forming an accommodating space between the first housing and the second housing. The first housing includes a first housing body and a limiting rib, the limiting rib being located on the inner wall of the first housing body, a fixing plate being connected to the limiting rib, and a sliding plate being located between the fixing plate and the first housing body.

[0010] Furthermore, the sliding structure also includes a pressing block and a switch operating part. The pressing block is disposed on the side of the sliding plate facing the circuit assembly, and the switch operating part is disposed on the side of the sliding plate away from the pressing block. The switch operating part is at least partially located within the switch clearance part.

[0011] Furthermore, both the first housing and the fixing structure are equipped with foolproof structures.

[0012] Furthermore, the anti-mistake structure includes an anti-mistake protrusion and an anti-mistake groove disposed on the outer edge of the fixing plate, wherein the anti-mistake protrusion and the anti-mistake groove are adapted to each other.

[0013] Furthermore, the assembly method for the remote control includes the following steps: installing a sliding structure at a predetermined position on the first housing; installing a fixing structure at a predetermined position on the first housing; installing a light guide at a predetermined position on the first housing; installing a circuit assembly at a predetermined position on the first housing; and assembling the second housing and the first housing.

[0014] According to another aspect of this application, an electronic device component is also provided, the electronic device component including an electronic device and a remote controller, the remote controller being the aforementioned remote controller.

[0015] By applying the technical solution of this application, when the operator operates the remote control, the sliding structure is operated at the corresponding position of the switch avoidance part. The sliding structure has a first position that abuts against the circuit component and a second position that disengages from the circuit component. When the sliding structure is in the first and second positions, the sliding structure and the fixed structure are engaged by convex and concave locking parts. This causes the pushing force of the sliding structure to change during the pushing process when sliding into or out of the first and second positions, resulting in different tactile sensations for the operator, thus improving the operator's experience. The technical solution of this application effectively solves the problem in the prior art that the pushing force is generally constant during the pushing process of electronic switches, which cannot meet the requirements for a buffered tactile sensation.

[0027] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0029] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways, rotated 90 degrees, or in other orientations, and the spatial relative descriptions used herein will be interpreted accordingly.

[0030] like Figures 1 to 7 As shown, the remote control of this embodiment includes: a housing 10, a switch assembly 20, and a circuit assembly 30. The housing 10 has a receiving space and a switch clearance portion 11 communicating with the receiving space and the outside of the housing 10. The switch assembly 20 includes a sliding structure 21 and a fixing structure 22. The fixing structure 22 is fixed in the receiving space, and the sliding structure 21 is at least partially disposed in the receiving space and corresponds to the switch clearance portion 11. The sliding structure 21 and the fixing structure 22 have mutually cooperating protrusion-contact locking portions. The circuit assembly 30 is disposed in the receiving space. The sliding structure 21 has a first position abutting against the circuit assembly 30 and a second position disengaging from the circuit assembly 30. When the sliding structure 21 is in the first position and the second position, both the sliding structure 21 and the fixing structure 22 are engaged by the protrusion-contact locking portions.

[0031] Applying the technical solution of this embodiment, when the operator operates the remote control, the sliding structure 21 is operated at the position corresponding to the switch avoidance part 11. The sliding structure 21 has a first position abutting against the circuit component 30 and a second position disengaging from the circuit component 30. When the sliding structure 21 is in the first and second positions, the sliding structure 21 and the fixed structure 22 are engaged by protruding and concave locking parts. This causes the pushing force of the sliding structure 21 to change during the pushing process when sliding into or out of the first and second positions, resulting in different tactile feedback for the operator, thus improving the operator's experience. The technical solution of this embodiment effectively solves the problem in the prior art that the pushing force is generally constant during the pushing process of electronic switches, which cannot meet the requirements for a buffered tactile feedback effect.

[0032] It should be noted that when the sliding structure 21 is in the first position, it abuts against the switch trigger part of the circuit assembly 30, thus achieving circuit connection and turning on the remote control. The length of the switch clearance part 11 in the direction of movement of the sliding structure 21 is adapted to the movement distance of the sliding structure 21, so that the switch clearance part 11 can provide a certain limit to the movement length of the sliding structure 21. The subsequent limiting rib 122 also limits the movement distance of the sliding structure 21. The protrusion 223 moves between the two grooves and cannot exceed the two grooves. The space between the two grooves is a flat plate, so that no jamming phenomenon will occur.

[0033] like Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, in this embodiment, the sliding structure 21 includes a sliding plate 211, and the convex-concave locking portion includes a first groove 2111, a second groove 2112, and a protrusion 223. The first groove 2111 and the second groove 2112 are located on the side of the sliding plate 211 facing the fixed structure 22, and the protrusion 223 is located on the side of the fixed structure 22 facing the sliding plate 211. This structure has low processing cost, is easy to operate, and has a long service life. Furthermore, the structure itself, provided by the sliding structure 21 and the fixed structure 22, eliminates the need for additional components, resulting in a compact and space-saving structure.

[0034] like Figures 4 to 6 As shown, in this embodiment, the fixing structure 22 includes a fixing plate 221 and an elastic cantilever 222. The fixing plate 221 has a central hollow and is fixedly connected to the housing 10. The first end of the elastic cantilever 222 is connected to the side wall of the fixing plate 221, and the second end of the elastic cantilever 222 is located within the central hollow. The protrusion 223 is located on the side of the second end of the elastic cantilever 222 facing the sliding plate 211. The structure of the fixing plate 221 and the elastic cantilever 222 improves the operating feel. The elastic cantilever 222 has the structural characteristics of a cantilever beam, thus possessing a certain degree of elasticity and adapting to certain elastic deformation. Compared to directly setting the protrusion 223 onto a rigid plate, the above structure provides a better feel.

[0035] like Figures 4 to 6As shown, in this embodiment, the protrusion 223 has an outer arc-shaped contour, while the first groove 2111 and the second groove 2112 both have inner arc-shaped contours. When the protrusion 223 and the first groove 2111 and the second groove 2112 undergo relative displacement, the transition is relatively smooth, further improving the operator's feel. It should be noted that the protrusion 223 is a spherical notch less than or equal to half a sphere, and the first groove 2111 and the second groove 2112 are both spherical notches adapted to the protrusion 223. Thus, the protrusion 223 and the first groove 2111, or the protrusion 223 and the second groove 2112, are in surface contact, meaning the contact area is relatively large. This results in a more stable relative displacement, leading to a better feel and higher movement accuracy of the sliding structure 21.

[0036] like Figures 2 to 7 As shown, in this embodiment, the housing 10 includes a first housing 12 and a second housing 13 that covers the first housing 12. A receiving space is formed between the first housing 12 and the second housing 13. The first housing 12 includes a first housing body 121 and a limiting rib 122. The limiting rib 122 is located on the inner wall of the first housing body 121. The fixing plate 221 is connected to the limiting rib 122, and the sliding plate 211 is located between the fixing plate 221 and the first housing body 121. The above structure ensures the moving accuracy of the sliding structure 21 and prevents it from deviating from the moving trajectory. It should be noted that in this embodiment, the limiting rib 122 forms a closed rectangular annular groove, and the sliding plate 211 is located in the rectangular annular groove. The limiting rib 122, the first housing body 121, and the fixing structure 22 together limit the sliding plate 211. It should be noted that the first housing body 121 and the limiting rib 122 are integrally formed structures. The fixing plate 221 is connected to the first housing 12 by fasteners, which are screws. The fixing plate 221 is a rectangular plate with through holes at its four corners. The four corners of the limiting rib 122 are also provided with screw holes corresponding to the through holes. The four screws pass through the corresponding through holes and engage with the screw holes to fix the fixing plate 221 on the limiting rib 122.

[0037] like Figure 6As shown, in this embodiment, the sliding structure 21 further includes a pressing block 212 and a switch operation part 213. The pressing block 212 is disposed on the side of the sliding plate 211 facing the circuit assembly 30, and the switch operation part 213 is disposed on the side of the sliding plate 211 away from the pressing block 212. The switch operation part 213 is at least partially located within the switch clearance part 11. The above structure is compact, and the pressing block 212 presses against the circuit assembly 30, while the switch operation part 213 is easy for the operator to operate. The highest point of the upper surface of the switch operation part 213 is flush with the outer surface of the first housing 12, thus reducing the risk of accidental operation. The upper surface of the switch operation part 213 is an arc-shaped surface that is high on both sides and low in the middle. This arc-shaped surface can be provided with operation markings, such as switch markings or markings indicating the direction of movement. It should be noted that the first housing located at both ends of the switch clearance part 11 can also be provided with markings indicating the direction of movement, for example, switch markings can be provided at both ends of the direction of movement of the sliding structure 21. In this embodiment, the surfaces at the contact points of the pressing block 212 and / or circuit assembly 30 can be beveled, curved, or smooth, so that the remote control is less likely to jam.

[0038] like Figure 2 and Figure 7 As shown, in this embodiment, both the first housing 12 and the fixing structure 22 are equipped with a foolproof structure. This structure provides high installation efficiency and reduces the likelihood of errors when installing the sliding structure 21 and the fixing structure 22 onto the first housing 12.

[0039] like Figure 2 and Figure 7 As shown, in this embodiment, the anti-mistake structure includes an anti-mistake protrusion 123 and an anti-mistake groove disposed on the outer edge of the fixing plate 221, with the anti-mistake protrusion 123 and the anti-mistake groove fitting together. This structure is convenient to operate and easy to manufacture. The anti-mistake structure that cooperates between the first housing 12 and the fixing structure 22 not only serves to prevent mistakes but also to provide positioning. It should be noted that the sidewall of the anti-mistake protrusion 123 facing the fixing plate 221 is a first arc shape, and the sidewall of the anti-mistake groove facing the anti-mistake protrusion 123 is a second arc shape; the contours of the first and second arc shapes fit together.

[0040] like Figure 2 and Figure 6 As shown, in this embodiment, the sliding structure 21 has a weight-reducing groove, which corresponds to the switch operation part 213, and the opening of the weight-reducing groove faces the circuit assembly 30. This structure further reduces the weight of the remote control and saves costs.

[0041] In summary, the electronic remote control toggle switch structure design of this embodiment includes an upper cover (first housing 12), a light guide, a toggle switch (switch operation part 213), a spring support arm (elastic cantilever 222), a PCBA main board, electronic switch components, screws, a battery, and a lower cover (second housing 13).

[0042] First, assemble the toggle button in the designated position on the top cover. Then, assemble the spring-loaded support arm in the designated position where the toggle button and the top cover meet. This fixes the range of motion of the toggle button. When the toggle button is pushed, the spring-loaded support arm, designed as a raised dot (protrusion 223), is positioned precisely within the groove of the toggle button after a certain stroke. This ensures accurate positioning and a smooth, tactile experience by creating a soft, cushioned feel when the toggle button is pushed.

[0043] Then, the four positioning posts of the top cover (first housing) are assembled with the holes of the elastic support arm, and then fixed by hot pressing. The light guide is then assembled in the designated position on the top cover to form a top cover assembly. The electronic switch element is pre-soldered and fixed to the designated position on the PCBA mainboard, and then the PCBA mainboard is assembled in the designated position on the top cover and fixed by screws. When the toggle switch is pushed, the trigger point of the electronic switch element aligns with the rib on the toggle switch, creating a braking effect. This allows for opening and closing to trigger electronic and electrical functions. The raised points of the elastic arm and the recessed points of the toggle switch create a raised-recessed dot effect, achieving positioning of the toggle switch when pushed and improving the cushioning feel when the toggle switch is activated.

[0044] After completing the above steps, fix the battery in the designated position on the top cover, and then solder it to the PCBA motherboard to generate power and realize electronic and electrical functions, forming a semi-finished component.

[0045] After completing the above steps, assemble the lower cover (second housing 13). The lower cover is fixed to the upper cover by using the snap-fit ​​and post assembly method to form a complete product (remote control).

[0046] This application, through the design of a spring-loaded support arm structure, can improve the accuracy of the toggle button positioning and enhance the feel of the toggle button when it is pushed, resulting in a good user experience.

[0047] When the toggle button is pushed, the protruding rubber part of the toggle button presses against the switch trigger part of the circuit assembly 30. The switch trigger part will sink downward under external force, generating an ON state. Conversely, when the switch trigger part and the protruding rubber part of the toggle button are separated by a certain distance, the switch is not subjected to external force, generating an OFF state. The distance between the first groove and the second groove needs to be synchronized with the switch travel.

[0048] According to this application, a method for assembling a remote control is also provided. The method includes the following steps: installing a sliding structure 21 at a predetermined position on a first housing 12; installing a fixing structure 22 at a predetermined position on the first housing 12; installing a light guide at a predetermined position on the first housing 12; installing a circuit assembly 30 at a predetermined position on the first housing 12; and assembling a second housing 13 and the first housing 12.

[0049] This application also provides an electronic device component, which includes an electronic device and a remote control, wherein the remote control is the aforementioned remote control. The electronic device can be an electronic device such as a television, projector, or game console, and the electronic device is electrically connected to the remote control.
