Description

Technical Field

[0001] This application relates to the field of wireless communications, and in particular to a wireless receiver head. Background Technology

[0002] Currently, there are various types of buttons on the market, and the technology is quite mature. Wireless receivers alone offer many button designs. Among these, the vast majority are based on flat designs. Buttons designed on curved surfaces are relatively rare, mainly because the structural fit is more complex.

[0003] Regarding the aforementioned technologies, the inventors believe that designing buttons on curved surfaces is rather complex. Summary of the Invention

[0004] To simplify the placement of buttons on curved surfaces, this application provides a wireless receiver head.

[0005] The wireless receiver head provided in this application adopts the following technical solution:

[0006] A wireless receiver includes a bottom shell, a button, and a spring-loaded drive button. The button is installed inside the bottom shell. The side wall of the bottom shell has an arc-shaped cross-section and protrudes outward relative to the button. A first notch is provided on the side wall of the bottom shell. The spring-loaded drive button is installed at the first notch. The spring-loaded drive button can indirectly trigger the button based on external pressing pressure.

[0007] By adopting the above technical solution, the size of the wireless receiver head is usually small. To make the wireless receiver head work, a button needs to be triggered. The button is often even smaller and is installed inside the bottom shell, so activating the button is quite troublesome.

[0008] In this application, by setting a flexible drive key and making the pressed area of ​​the flexible drive key larger than the pressed area of ​​the button, it is easier to trigger the button to work.

[0009] Furthermore, if the spring-loaded button is installed on the bottom surface of the wireless receiver, it cannot be pressed normally; if the spring-loaded button is installed on the top surface, it is easily pressed accidentally and affects the appearance.

[0010] In this application, by installing the flexible drive button on the side wall of the bottom shell of the wireless receiver head, it is possible to effectively prevent accidental pressing and facilitate normal button triggering.

[0011] This invention provides a new approach and method for triggering buttons on products with extremely small dimensions and curved housings. Specifically, this application allows for the easy installation of a flexible drive button on the inclined surface of the product, thereby facilitating button triggering.

[0012] Preferably, the elastic drive key is located in the center of the notch. The elastic drive key includes an integrally formed actuating part, a counterweight part, and a pressing part. The actuating part is movably disposed in the bottom shell. The pressing part is installed at the first notch and can drive the actuating part to move based on external pressing force so that the actuating part triggers the button. The counterweight part is located in the bottom shell and is connected between the pressing part and the actuating part.

[0013] By adopting the above technical solution, when the button needs to be activated, force is applied to the pressing part, which is then transmitted to the actuator, causing it to move. Once the actuator reaches the predetermined position, it can directly trigger the button. The elastic drive button is centrally symmetrically arranged, which allows for more even distribution of pressing force. Even when the user presses only the edge of the pressing part, the actuator can still receive some pressure to activate the button. Simultaneously, it reduces the impact of uneven force distribution on the elastic drive button, thereby extending its service life.

[0014] Preferably, the counterweight is fixedly connected to the upper surfaces of the actuating part and the pressing part, and grooves are provided on the upper surfaces of the actuating part and the pressing part, respectively, and the grooves of the actuating part and the pressing part are located on both sides of the counterweight.

[0015] By adopting the above technical solution, the elastic drive key, which is typically manufactured using the molding process for plastic parts, features grooves in the actuator and pressing parts (i.e., the elastic drive key has a hollow design). This hollow design makes the molding of the elastic drive key more uniform and saves material. The overall weight of the elastic drive key is reduced, and when the user presses the pressing part, no force is required to cause the actuator to move in the direction of the button, thereby triggering the button to work.

[0016] Preferably, the actuator includes symmetrically arranged cantilever arms and contact blocks, the cantilever arms and the contact blocks are integrally connected, the symmetrically arranged cantilever arms are located on both sides of the contact blocks, the cantilever arms are arc-shaped, and the arc is the same as the arc of the bottom shell sidewall.

[0017] By adopting the above technical solution, the arc design of the cantilever can provide the deformation space caused by the stroke of the pressing part when it is pressed down. When the pressing part is pressed, the cantilever deforms, causing the contact block to move in the direction of the button, thereby triggering the button (when the button needs to be triggered, if the button is a mechanical button, the contact block needs to press the mechanical button; if the button is a sensor, the contact block moves into the button's sensing range to trigger the sensor button to work).

[0018] When the pressing part is released, the cantilever returns to its natural shape, and the contact block and pressing part return to their initial positions. This process relies solely on elastic restoring force to achieve reset, making the entire structure simpler. The curvature and length of the cantilever are set according to the installation location. If the cantilever on both sides is too short, the elastic drive key deformation is insufficient, making the elastic drive key difficult to press or even impossible to press. If the cantilever is too long, the elastic drive key's rebound force will be insufficient, and the elastic drive key will not function properly.

[0019] Preferably, the cantilever is arranged in a stepped manner, with one end away from the contact block and the other end higher than the cantilever and closer to the contact block. A limiting groove is formed at the end away from the contact block, and a limiting block is provided on the bottom shell. The limiting groove and the limiting block are engaged.

[0020] By adopting the above technical solution, the height setting of the cantilever structure makes the cantilever more easily deformable. Moreover, when the elastic drive key is subjected to pressure, the cantilever deforms, resulting in a good pressing feel and enhancing the tactile feedback of the elastic drive key. The height of the outermost end of the cantilever is matched with the height of the limiting block. When the cantilever deforms, it ensures that the cantilever can move within the required stroke while also ensuring that the limiting block pulls the cantilever from both sides, causing the cantilever to return to its original position without collapse, thus ensuring an aesthetically pleasing appearance after repositioning.

[0021] Preferably, the bottom shell is detachably connected to the upper shell, and the upper shell and the bottom shell are snapped together. The snap-fit ​​upper shell and the bottom shell simultaneously snap together the pressing part. The top surface of the pressing part is flush with the top surface of the side wall of the bottom shell. The pressing part is specifically a keycap.

[0022] By adopting the above technical solution, the keycaps are effectively restrained when the upper and lower shells are snapped together, preventing them from easily falling off even during bumpy transportation or installation. The top surface of the keycaps is flush with the top surface of the side wall of the lower shell, meaning the spring-loaded keys are not exposed separately compared to the upper and lower shells, reducing the probability of accidental pressing. When the keycaps are pressed, they do not affect the upper shell, and the overall appearance is more aesthetically pleasing.

[0023] Preferably, the keycap has a protrusion on the side facing away from the button, and the protrusion has an anti-slip texture.

[0024] By adopting the above technical solution, the keycaps are provided with raised and anti-slip textures on the outside, making the contact surface of the keycaps rougher, increasing friction, and preventing the user's hand from slipping off the spring-loaded key; at the same time, even if the user is not looking at the wireless receiver, they can quickly find the spring-loaded key, providing better prompting for the user.

[0025] Preferably, the counterweight part includes a counterweight block and a connecting block, the connecting block is between the execution part and the pressing part, the counterweight block is connected to both sides of the connecting block, and two counterweight blocks are simultaneously connected to the execution part and the pressing part.

[0026] By adopting the above technical solution, the counterweight increases the strength of the contact block and keycap, thereby increasing the stability and reliability of the elastic drive key. Simultaneously, when the upper shell is pressed down, the counterweight contacts the upper shell, ensuring stable pressure on the counterweight and making the pressing process more stable. It also cooperates with the bottom shell for easy sliding, and the overall weight distribution enhances the stability of the elastic drive key structure, preventing the elastic drive key from easily detaching from the shell even during the transportation or installation of the wireless receiver head.

[0027] Preferably, the counterweights extend in a direction away from each other relative to the keycaps, the overall length of the two counterweights is greater than the length of the first notch, a protrusion is provided on the side wall of the bottom shell near the first notch, and a gap is provided between the protrusion and the adjacent counterweight.

[0028] By adopting the above technical solution, since the lateral length of the counterweight is greater than the length of the notch, when the elastic drive key is loosened, the counterweight abuts against the notch, preventing the elastic drive key from detaching outward.

[0029] When the spring-loaded key is not pressed, the gap between the bump and the weight is to facilitate the installation of the spring-loaded key in the wireless receiver head, while also allowing for less precise dimensional control during the manufacturing of the wireless receiver head. When the user presses the spring-loaded key firmly, the keycap presses downwards, and the keycap and weight may undergo slight lateral deformation; the gap provides a buffer space for the keycap and weight.

[0030] Preferably, a PCB board is detachably installed inside the base plate, the base plate is provided with a limiting post, the PCB board is provided with a limiting hole, and the limiting post is inserted into the limiting hole.

[0031] By adopting the above technical solution, the PCB board is an essential component of the wireless receiver head. The PCB board is snapped onto the bottom shell. When installing or transporting the wireless receiver head, the PCB board, which is firmly attached to the bottom shell, can reduce collisions and protect the PCB board.

[0032] In summary, this application includes at least one of the following beneficial technical effects:

[0033] 1. The buttons can be installed on a wider range of surfaces, including curved surfaces;

[0034] 2. The button structure is simpler, requiring no resetter, and the buttons can automatically reset. Attached Figure Description

[0043] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0044] This application discloses a wireless receiver head. (Refer to...) Figure 1 and Figure 2 A wireless receiver includes a housing, a button 4, and a resilient drive button 5. The button 4 is located inside the housing, and the resilient drive button 5 is partially located inside the housing and partially engaged with the side wall of the housing. When the resilient drive button 5 located on the side wall of the housing is pressed, the button 4 is triggered to connect the entire circuit of the wireless receiver, thereby activating the wireless receiver.

[0045] Reference Figure 1 The housing has an arc-shaped sidewall and is divided into an upper shell 1 and a bottom shell 3. The upper shell 1 and the bottom shell 3 are snap-fitted together, allowing the internal components of the wireless receiver to be assembled into a complete product. (Refer to...) Figure 2The specific assembly method is as follows: an annular wall 34 is provided on the inner side wall of the bottom shell 3, and an annular groove (not marked in the figure) is provided on the inner side of the upper shell 1. The annular groove and the annular wall 34 are engaged, thereby enabling the upper shell 1 and the bottom shell 3 to be assembled together. (Refer to...) Figure 1 The bottom surface of the bottom shell 3 is provided with a ring base 7, which makes it easy for users to place the wireless receiver head.

[0046] Reference Figure 2 The bottom shell 3 also houses a PCB board 2. To ensure the PCB board 2 is securely positioned within the shell, two limiting holes 21 are provided on the PCB board 2. Two limiting posts 32 are installed inside the bottom shell 3, spaced apart. The limiting holes 21 and the limiting posts 32 are interlocked. When the limiting posts 32 are inserted into the corresponding limiting holes 21, the PCB board 2 is fixed to the bottom shell.

[0047] Reference Figure 3 A first notch 8 is provided on the side wall of the bottom shell 3, and the elastic drive key 5 is located at the position of the first notch 8. The outer arc of the elastic drive key 5 away from the annular wall 34 is the same as the side arc of the bottom shell 3. When the elastic drive key 5 is pressed, the elastic drive key 5 can slide along the center direction of the bottom shell 3 and gradually approach the button 4. When the distance between the elastic drive key 5 and the button 4 is small enough to reach a predetermined distance, the button 4 can be triggered to connect the entire circuit.

[0048] Reference Figure 3 A second notch 9 is provided on the annular wall 34, and the first notch 8 is connected to the second notch 9. The opening of the second notch 9 along the arc length direction is larger than the opening of the first notch 8 along the arc length direction. The elastic drive key 5 is engaged at the first notch 8 and the second notch 9. In this way, the elastic drive key 5 can be limited, reducing the likelihood of the elastic drive key 5 easily disengaging from the first notch 8.

[0049] refer to Figure 3 The elastic drive key 5 includes an integrally formed actuator 51, a counterweight 52, and a pressing part 53. The actuator 51 faces the button 4, and the pressing part 53 is placed at the first notch 8. The pressing part 53 can drive the actuator 51 to slide based on external pressing pressure, so that the actuator 51 triggers the button 4. The counterweight 52 is connected between the pressing part 53 and the actuator 51. By pressing the pressing part 53, the actuator 51 is driven to move closer to the button 4, thereby directly or indirectly triggering the button 4 (if the button 4 is a mechanical button, pressing the mechanical button can indirectly trigger the wireless receiver to work; if the button 4 is a sensor, the elastic drive key 5 can move into the sensing range of the button 4 to indirectly trigger the wireless receiver to work).

[0050] Reference Figure 4When the upper shell 1 is closed, the PCB board 2 partially presses against the upper surface of the elastic drive key 5, abutting against the elastic drive key 5. Simultaneously, the upper shell 1 partially presses against the upper surface of the elastic drive key 5. The combined pressure of the upper shell 1 and the PCB board 2 on the elastic drive key 5 stabilizes its position and prevents it from moving up or down. When the elastic drive key 5 becomes loose, the counterweight 52 abuts against the side wall of the bottom shell 3, preventing the elastic drive key 5 from falling outwards. At the same time, the counterweight 52 abuts against both the upper shell 1 and the bottom shell 3, effectively reducing the up-down and left-right movement of the entire elastic drive key 5, thus providing stability.

[0051] Reference Figure 4 The pressing part 53 is specifically a keycap 531. The top surface of the keycap 531 is arc-shaped and flush with the side wall of the bottom shell 3. There is a protrusion on the outer wall of the keycap 531, and the protrusion has anti-slip texture.

[0052] Reference Figure 5 The counterweight 52 includes a counterweight block 521 and a connecting block 522. The connecting block 522 is fixedly installed between the actuating part 51 and the pressing part 53. The two sides of the connecting block 522 are connected to the counterweight block 521. The bottom sides of the two counterweight blocks 521 are simultaneously connected to the upper surfaces of the actuating part 51 and the pressing part 53. The two counterweight parts 52 extend relative to the keycap 531 in a direction away from each other. (Refer to...) Figure 6 The overall length of the two counterweights 521 and the connecting block 522 is greater than the length of the first notch 8. When the elastic drive key 5 is loosened, the counterweight 521 gets stuck at the first notch 8 and cannot fall out.

[0053] refer to Figure 5 The counterweight 521 has a slider 523 at its bottom end, and a fixing block 37 is provided at the second notch 9 (see reference). Figure 3 The slider 523 abuts against the fixed block 37. When the pressing part 53 is pressed, the slider 523 slides on the surface of the fixed block 37. During the sliding process, only the arc surface of the slider 523 contacts the fixed block 37. In this way, the friction of the counterweight 521 during the sliding process can be reduced, thereby reducing the pressing force of the user pressing the elastic drive key 5.

[0054] Reference Figure 5 The actuator 51 includes a cantilever 511 and a contact block 512 that are symmetrical to each other. The contact block 512 is rectangular. The cantilever 511 is symmetrically arranged on both sides of the contact block 512. The cantilever 511 is arc-shaped and the arc of the cantilever 511 is consistent with the arc of the side wall of the bottom shell 3. The longitudinal section of the cantilever 511 is stepped. Specifically, the end away from the contact block 512 is higher than the end of the cantilever 511 that is close to the contact block 512. A limiting groove 513 is opened at the end away from the contact block 512.

[0055] Reference Figure 6The bottom shell 3 is provided with two limiting blocks 31, and the limiting blocks 31 and the inner ring block 35 form a through groove 36 (see reference). Figure 3 Limiting block 31 and limiting groove 513 (refer to) Figure 5 The engagement is achieved through the through groove 36. When the pressing part 53 is pressed down, the contact block 512 moves closer to the button 4, and the cantilever 511 on both sides of the contact block 512 undergoes elastic deformation and extends to both sides. At this time, the cantilever 511 engaged with the through groove 36 is abutted by the side wall of the through groove 36, and the two cantilever 511 cannot continue to extend to both sides. When the pressing part 53 is released, the cantilever 511 returns to its original deformation and naturally resets.

[0056] Reference Figure 7 A protrusion 33 is provided at the second notch 9, and the protrusion 33 is integrally formed with the annular wall 34. The protrusion 33 increases the cross-sectional area at the notch of the annular wall 34, and there is a gap between the protrusion 33 and the counterweight 521. The presence of the protrusion 33 causes the local cross-section of the annular wall 34 to increase the plasticity of the annular wall 34. When the counterweight 521 touches the annular wall 34, the annular wall 34 is not easy to break or deform. The gap between the protrusion 33 and the counterweight 521 makes the installation of the elastic drive key 5 more convenient, and does not affect the normal operation of part of the structure of the elastic drive key 5, and will not cause the elastic drive key 5 to be exposed due to excessive gap.

[0057] Reference Figure 7 Furthermore, the material of the elastic drive key 5 can be one or more of PC or ABS. In this embodiment, the material of the elastic drive key 5 is not limited; however, any elastic drive key 5 that achieves the effect of elastic force is within the protection scope of this application. Grooves 6 are respectively formed on the contact block 512 and the pressing part 53. The grooves 6 are located on both sides of the connecting block 522 and are hollowed out during the molding process of the plastic part, making the molding of the elastic drive key 5 more uniform and saving material. The overall weight of the elastic drive key 5 is reduced, and the user can also achieve a labor-saving effect when pressing the pressing part 53.

[0058] The implementation principle of a wireless receiver head according to an embodiment of this application is as follows: A first notch 8 is provided on the side wall of the bottom shell 3 of the wireless receiver head, and an elastic drive key 5 is installed at the first notch 8. The elastic drive key 5 includes an arc-shaped cantilever 511 and a contact block 512. When the elastic drive key 5 is pressed, the cantilever 511 undergoes elastic deformation, which drives the contact block 512 to directly or indirectly trigger the button 4. After the button 4 is triggered, it can connect the working circuit of the wireless receiver head, thereby enabling the wireless receiver head to start working.

[0059] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
