Technical Field
[0001] This utility model relates to the field of remote control technology, and in particular to a silicone button plate for a call device. Background Technology
[0002] In today's era of rapid technological development, pagers, as a convenient communication device, are widely used in hospitals, nursing homes, hotels, and many other places to meet people's needs for quick communication and assistance in different scenarios. Therefore, a silicone button plate for pagers is required.
[0003] A search revealed Chinese Patent Publication No. CN221901152U, which discloses a remote control that is easy to assemble and disassemble. The remote control includes: a housing and a button assembly and a support frame assembly disposed within the housing. The housing has a vertically penetrating insertion channel, and the front of the housing has an opening connecting the insertion channel to the outside. After the support frame assembly is inserted into the insertion channel, it presses the button assembly against the opening. The support frame assembly includes an upper support frame and a lower support frame. The upper support frame has first limiting grooves on both sides, and the lower support frame has second limiting grooves on both sides. The button assembly has a first limiting protrusion and a second limiting protrusion. After the upper and lower support frames are inserted into the insertion channel from their respective upper and lower ends, they abut against the back of the button assembly, and the first and second limiting protrusions respectively engage with the corresponding first and second limiting grooves. However, the existing circuit boards are fixed inside the device with screws. When the device is accidentally dropped, the internal circuit boards are easily damaged due to the lack of cushioning, which affects the normal use of the device. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a silicone button plate for a call device, which aims to improve the problem in the prior art where the internal circuit board is easily damaged due to lack of cushioning when the device is accidentally dropped, thus affecting the normal use of the device.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a silicone button plate for a call device, comprising a bottom shell, a connecting groove 1 formed in the middle of the inner wall of the bottom shell, a buffer pad provided on the inner wall of the connecting groove 1, connecting groove 2 formed on both the front and back of the inner wall of the bottom shell, silicone pads provided on the inner walls of both connecting groove 2, a circuit board provided on the top of the inner wall of the bottom shell, a cover plate provided on the top of the outer wall of the bottom shell, multiple buttons provided on the left and right sides of the top of the cover plate, conductive particles fixedly connected to the bottom perimeter of the multiple buttons, multiple fixing cylinders fixedly connected to the left and right sides of the inner wall of the bottom shell, springs fixedly connected to the inner walls of the multiple fixing cylinders, multiple connecting cylinder 1s fixedly connected to the bottom left and right sides of the circuit board, the bottom ends of the multiple connecting cylinder 1s engaging with the tops of the springs, and a fixing mechanism provided at the bottom of the circuit board.
[0006] The above technical solution involves: a connecting groove 1 located in the middle of the inner wall of the bottom shell, with a buffer pad placed therein. The buffer pad provides cushioning for the circuit board in the vertical direction. When the call device is subjected to external impact, collision, or drop, the buffer pad can first absorb some of the energy, reducing the direct transmission of impact force to the circuit board. Two connecting grooves 2 are located at the front and back of the inner wall of the bottom shell, with silicone pads placed therein. The silicone pads mainly provide cushioning and stabilization for the circuit board in the front-back direction, preventing the circuit board from colliding hard with the bottom shell when it shakes back and forth. At the same time, they can also provide a certain elastic deformation space to absorb energy when impacted. The multiple buttons on the top of the cover are the operating components for user interaction with the call device. The conductive particles fixedly connected around the bottom of the buttons are the key conductive components for realizing the button functions. When the button is pressed, the conductive particles contact the corresponding contacts on the circuit board, forming a conductive path, thereby triggering the corresponding function of the call device. Multiple fixed cylinders and springs on the left and right sides of the inner wall of the bottom shell constitute an elastic support structure. The connecting cylinders 1 on the left and right sides of the bottom of the circuit board engage with the top of the spring, allowing the circuit board to suspend inside the bottom shell and be elastically supported by the spring.
[0007] As a further description of the above technical solution:
[0008] The fixing mechanism includes a connecting plate, the top of which is fixedly connected to the bottom of the bottom shell. Multiple engaging holes are provided on the front and rear sides of the connecting plate. Multiple grooves are provided on the front and rear sides of the inner wall of the bottom shell. A fixing post is fixedly connected to the inner wall of each of the multiple grooves. A engaging post is fixedly connected to the top of each of the multiple fixing posts. The top of each engaging post engages with the engaging holes.
[0009] The above technical solution utilizes a connecting plate as a crucial component of the fixing mechanism. Its top is fixedly connected to the bottom of the base shell, serving as a bridge connecting the base shell to other components. Multiple locking holes on the front and rear sides of the connecting plate engage with locking posts on the fixing posts in the grooves on the front and rear sides of the inner wall of the base shell. This locking structure achieves a tight connection between the base shell and the connecting plate, ensuring the stability of the locking while facilitating assembly. The fixing posts fix the locking posts to the inner wall of the grooves, ensuring not only the stability of the locking posts' position but also sufficient strength to withstand tensile and shear forces.
[0010] As a further description of the above technical solution:
[0011] The outer wall of the cover plate is provided with multiple limiting grooves, and the inner wall of the bottom shell is fixedly connected with multiple buckles, and the inner wall of the multiple limiting grooves engages with the outer wall of the buckles.
[0012] The above technical solution allows for a tighter connection between the cover plate and the bottom shell after the buckle and the limiting groove engage. This helps improve the sealing of the entire silicone button board, which is of great significance in preventing dust, moisture and impurities from entering the equipment. It can effectively protect the normal operation of the internal components of the circuit board and extend the service life of the equipment.
[0013] As a further description of the above technical solution:
[0014] Multiple connecting cylinders are fixedly connected to the inner wall of the bottom shell. Multiple limiting holes are opened on the outer wall of the cover plate. Screws are fixedly threaded to the outer walls of the multiple limiting holes. The multiple limiting holes are threaded to the connecting cylinders through the screws.
[0015] The above technical solution provides a channel for the screw to pass through and a positioning function through the limiting holes around the outer wall of the cover plate. The diameter of the limiting hole is slightly larger than the screw shank diameter so that the screw can pass through smoothly and be threadedly connected to the connecting cylinder two. The screw, through the cooperation with the limiting hole and the thread engagement in the connecting cylinder two, firmly fixes the cover plate to the bottom shell.
[0016] As a further description of the above technical solution:
[0017] A battery compartment is fixedly connected to the bottom left side of the bottom shell, and a cover is provided on the outer wall of the battery compartment.
[0018] The above technical solution provides a dedicated space for the battery through the battery compartment, allowing it to be stably installed inside the device and preventing it from shaking or shifting during device movement or use, thus ensuring the reliability of the electrical connection. The cover further enhances the protection of the battery, preventing it from falling out due to external impact or misoperation.
[0019] As a further description of the above technical solution:
[0020] A semi-circular groove is provided on the bottom right side of the bottom shell, and the semi-circular groove is designed to be smooth.
[0021] The above technical solution ensures that the smooth edges and surfaces prevent fingers from feeling rough when in contact with the semi-circular groove, minimizing discomfort. During gripping, the friction between the fingers and the smooth semi-circular groove is more evenly distributed. Compared to designs with sharp edges, there is no excessive local pressure or the sharp edges scratching the fingers, which would affect the grip.
[0022] As a further description of the above technical solution:
[0023] The bottom of the circuit board is connected to multiple fixing posts 2 around its perimeter, and the inner walls of the multiple fixing posts 2 engage with the connecting cylinder 2.
[0024] The above technical solution allows for precise determination of the circuit board's position within the bottom shell through the engagement of the fixed post 2 and the connecting cylinder 2, preventing displacement of the circuit board in the horizontal and vertical directions and ensuring accurate matching between the electronic components on the circuit board and the conductive particles of the buttons.
[0025] As a further description of the above technical solution:
[0026] Multiple fixed cylinders are equidistantly fixedly connected to the left and right sides of the inner wall of the bottom shell, and multiple connecting cylinders are equidistantly fixedly connected to the left and right sides of the bottom of the circuit board.
[0027] The above technical solution involves fixing the circuit boards at equal intervals to the left and right sides of the inner wall of the bottom shell. This ensures that the supporting force borne by each fixing cylinder is distributed relatively evenly, which helps to ensure that the circuit board receives consistent support at various positions within the bottom shell. This avoids the circuit board tilting and deforming due to uneven local force, and maintains the stability of the circuit board in the horizontal direction.
[0028] This utility model has the following beneficial effects:
[0029] 1. In this utility model, the buffer pad in the first connecting groove can effectively absorb and disperse the energy generated when the equipment is subjected to external impact in the vertical direction, which can reduce the impact force on the circuit board in the vertical direction. The silicone pad in the second connecting groove is in the front-back direction to prevent the circuit board from shaking back and forth and colliding hard with the bottom shell. The spring in the fixing cylinder is engaged with the first connecting cylinder at the bottom of the circuit board. When it is impacted, the spring undergoes elastic deformation according to the magnitude of the impact force, further buffering the remaining impact force, effectively protecting the overall structural integrity of the circuit board and reducing the possibility of damage to components due to uneven force.
[0030] 2. In this utility model, the precise positioning between the bottom shell and the connecting plate is achieved through the cooperation of multiple locking pins and locking holes. During the assembly process, the locking pins can be accurately inserted into the corresponding locking holes to ensure that the relative positions of the bottom shell and the connecting plate in the horizontal and vertical directions are accurate, thereby reducing manual intervention and assembly time.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0039] Reference Figure 1 , Figure 2 and Figure 4An embodiment of this utility model provides a silicone button plate for a call device, comprising a bottom shell 1, characterized in that: a connecting groove 3 is provided in the middle of the inner wall of the bottom shell 1, a buffer pad 4 is provided on the inner wall of the connecting groove 3, a connecting groove 5 is provided on both the front and back of the inner wall of the bottom shell 1, a silicone pad 6 is provided on the inner wall of both connecting grooves 5, a circuit board 7 is provided on the top of the inner wall of the bottom shell 1, a cover plate 8 is provided on the top of the outer wall of the bottom shell 1, a plurality of buttons 9 are provided on the left and right sides of the top of the cover plate 8, conductive particles 10 are fixedly connected to the bottom of the plurality of buttons 9, a plurality of fixing cylinders 11 are fixedly connected to the left and right sides of the inner wall of the bottom shell 1, a spring 12 is fixedly connected to the inner wall of the plurality of fixing cylinders 11, a plurality of connecting cylinders 13 are fixedly connected to the left and right sides of the bottom of the circuit board 7, the bottom ends of the plurality of connecting cylinders 13 engage with the top of the spring 12, and a fixing mechanism 2 is provided at the bottom of the circuit board 7;
[0040] Specifically, the circuit board 7 is placed on the top of the inner wall of the bottom shell 1. Multiple connecting cylinders 13 on its bottom left and right sides engage with springs 12 inside the fixing cylinders 11 on the left and right sides of the inner wall of the bottom shell 1. The circuit board 7 is suspended and fixed inside the bottom shell 1. Under normal conditions, the springs 12 are in a naturally extended state, providing upward support for the circuit board 7, ensuring that the circuit board 7 is stably positioned within the bottom shell 1, preventing it from shaking or shifting, and ensuring the stability of the components and circuit connections on the circuit board 7. When the call device is subjected to external impact, the impact force is transmitted to the bottom shell 1. At this time, the buffer pad 4 in the connecting groove 3 in the middle of the inner wall of the bottom shell 1 and the silicone pads 6 in the connecting grooves 5 at the front and rear will first play a buffering role. The buffer pad 4 mainly acts in the vertical direction. The silicone pad 6 absorbs and disperses some of the impact force, reducing the energy directly transmitted to the circuit board 7. The silicone pad 6 prevents the circuit board 7 from colliding hard with the bottom shell 1 in the front-back direction, thus buffering and stabilizing the circuit board 7. At the same time, the spring 12 inside the fixing cylinder 11 will also undergo elastic deformation according to the magnitude of the impact force, further absorbing and buffering the remaining impact force. When using the call device, the user can trigger the corresponding function by pressing the multiple buttons 9 on the top left and right sides of the cover plate 8. When the button 9 is pressed, the conductive particles 10 fixedly connected around the bottom of the button 9 will move downward along with the button 9. Since the circuit board 7 is fixed in the bottom shell 1, the conductive particles 10 will gradually approach and eventually contact the corresponding conductive contacts on the circuit board 7 during the stroke of the button 9 being pressed.
[0041] Reference Figure 4 and Figure 5The fixing mechanism 2 includes a connecting plate 201. The top of the connecting plate 201 is fixedly connected to the bottom of the bottom shell 1. Multiple engaging holes 204 are provided on the front and rear sides of the connecting plate 201. Multiple grooves 205 are provided on the front and rear sides of the inner wall of the bottom shell 1. Fixed posts 202 are fixedly connected to the inner walls of the multiple grooves 205. Engaging posts 203 are fixedly connected to the top of the multiple fixed posts 202. The tops of the multiple engaging posts 203 engage with the engaging holes 204.
[0042] Specifically, when assembling the call device, the bottom shell 1 and the connecting plate 201 are first connected to the locking pin 103 through the locking hole 204. The worker will align the bottom shell 1 with the fixing pin 202 and the locking pin 203 with the connecting plate 201, so that the locking pin 203 in the groove 205 on the front and rear sides of the inner wall of the bottom shell 1 corresponds to the locking hole 204 on the front and rear sides of the connecting plate 201. Since the top of the locking pin 203 is designed to be easy to insert, after applying a certain pressure, the locking pin 203 can be smoothly inserted into the locking hole 204. As the locking pin 203 continues to go deeper into the locking hole 204, a tight fit will gradually be formed between the two. Relying on the shape of the locking pin 203 itself and the elasticity of the material, a stable locking state is finally achieved, thus firmly connecting the bottom shell 1 and the connecting plate 201 together.
[0043] Reference Figure 1 , Figure 2 and Figure 3 The outer wall of the cover plate 8 is provided with multiple limiting grooves 14, and the inner wall of the bottom shell 1 is fixedly connected with multiple buckles 15. The inner wall of the multiple limiting grooves 14 engages with the outer wall of the buckles 15. Multiple connecting cylinders 16 are fixedly connected to the inner wall of the bottom shell 1. Multiple limiting holes 21 are provided to the outer wall of the cover plate 8. Screws 17 are fixedly threaded to the outer wall of the multiple limiting holes 21. The multiple limiting holes 21 are threadedly connected to the connecting cylinders 16 through the screws 17. A battery compartment 18 is fixedly connected to the bottom left side of the bottom shell 1. A cover 19 is provided on the outer wall of the battery compartment 18.
[0044] Specifically, during the assembly of the cover plate 8 and the bottom shell 1, when the cover plate 8 is placed on top of the bottom shell 1 and gradually brought closer, multiple latches 15 on the inner wall of the bottom shell 1 will correspond to multiple limiting grooves 14 on the outer wall of the cover plate 8. Since the latches 15 have a certain elastic deformation capability, after applying slight pressure, the latches 15 can smoothly slide into the limiting grooves 14. The battery compartment 18 on the bottom left side of the bottom shell 1 provides a dedicated space for the battery. When the battery is placed in the battery compartment 18, the cover 19 on the outer wall of the battery compartment 18 takes effect. The latches 15 on the edge of the cover 19 cooperate with the outer wall of the battery compartment 18. By pressing the cover 19, the latches 15 are engaged in the slots or protrusions on the outer wall of the battery compartment 18, thereby fixing the cover 19 to the battery compartment 18.
[0045] Reference Figure 2 , Figure 3 and Figure 4 A semi-circular groove 20 is provided on the right side of the bottom of the bottom shell 1. The semi-circular groove 20 has a smooth design. Multiple fixing posts 22 are connected around the bottom of the circuit board 7. The inner wall of the multiple fixing posts 22 engages with the connecting cylinder 16. Multiple fixing cylinders 11 are fixedly connected at equal intervals to the left and right sides of the inner wall of the bottom shell 1. Multiple connecting cylinders 13 are fixedly connected at equal intervals to the left and right sides of the bottom of the circuit board 7.
[0046] Specifically, when a user picks up the call device, the smoothly designed semi-circular groove 20 on the bottom right side of the base shell 1 plays a crucial role. The fingers naturally rest on the semi-circular groove 20, its smooth curve matching the physiological curvature of the fingers, allowing for a comfortable and stable grip. The shape of the connecting cylinder 16 matches the fixing post 22, enabling the fixing post 22 to accurately insert into the connecting cylinder 16, determining the precise position of the circuit board 7 within the base shell 1, ensuring the relative position of the circuit board 7 and the base shell 1 is fixed, and preventing unnecessary displacement of the circuit board 7 in the horizontal and vertical directions. Multiple fixing cylinders 11 are equidistantly fixed to the left and right sides of the inner wall of the base shell 1, and multiple connecting cylinders 13 are equidistantly fixed to the left and right sides of the bottom of the circuit board 7, ensuring that the supporting force on the circuit board 7 is evenly distributed.
[0047] Working principle: The circuit board 7 is suspended and fixed by the engagement of the connecting cylinder 13 and the spring 12 inside the fixing cylinder 11 on the inner wall of the bottom shell 1. When subjected to external impact, the bottom shell 1 receives the impact force, the buffer pad 4 of the connecting groove 1 absorbs and disperses the energy in the vertical direction, reducing the impact on the circuit board 7. The silicone pad 6 of the connecting groove 2 prevents the circuit board 7 from colliding hard with the bottom shell 1 in the front and back direction, and works together to stabilize the circuit board 7. The spring 12 inside the fixing cylinder 11 deforms elastically according to the impact force, buffering the remaining impact and protecting the circuit board 7 and its components. In terms of operation, the user presses the button 9 on the cover plate 8 to trigger the function. Pressing the button 9 causes the conductive particles 10 to move down. Since the position of the circuit board 7 is fixed, the conductive particles 10 approach and contact the corresponding conductive contacts of the circuit board 7 to form a conductive path. The signal completes the call and hang-up operation through the preset circuit of the circuit board 7.
[0048] Furthermore, when assembling the call device, the staff first connects the bottom shell 1 and the connecting plate 201 through the engaging holes 204 and engaging posts 203. The staff aligns the bottom shell 1, which has a fixing post 202 and engaging posts 203, with the connecting plate 201, so that the engaging posts 203 in the grooves 205 on the front and back sides of the inner wall of the bottom shell 1 correspond to the engaging holes 204 on the front and back sides of the connecting plate 201. Since the top of the engaging post 203 is designed to be easy to insert, after applying a certain amount of pressure, the engaging post 203 can be smoothly inserted into the engaging hole 204. As the engaging post 203 continues to go deeper into the engaging hole 204, a tight fit will gradually be formed between the two. Relying on the shape of the engaging post 203 itself and the elasticity of the material, a stable engagement state is finally achieved, thus firmly connecting the bottom shell 1 and the connecting plate 201 together.
[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
