Description

Technical Field

[0001] The utility model relates to the field of buttons, in particular to a waterproof silica gel button for electronic products. Background Art

[0002] Electronic products are related products that use electricity as the basis for their work, mainly including: watches, smart phones, telephones, televisions, video players (VCD, SVCD, DVD), video recorders, camcorders, radios, radio recorders, combination speakers, laser players (CD), computers, game consoles, mobile communication products, etc. Among them, video recorders, camcorders, game consoles and other products all require the use of buttons to achieve the function of operating the products. Existing electronic products all use silicone buttons, which have a certain hardness, such as the buttons of laptops, and silicone buttons have a comfortable pressing effect, but they are not waterproof. When in use, there are gaps between the silicone buttons and the outer casing of the product. These gaps will cause water to penetrate, causing water to enter the interior of the product and contact the product's circuit board. In order to solve the above problems, we propose a waterproof silicone button for electronic products. Utility Model Content

[0003] The utility model aims to provide a waterproof silica gel keypad for electronic products, which has the advantage of being waterproof.

[0004] The above technical objectives of the present utility model are achieved through the following technical solutions: a waterproof silicone button for electronic products, comprising a shell, a sealing groove is provided on the top of the shell, a sealing ring is sealingly and slidingly connected to the inside of the sealing groove, a silicone button is fixedly sleeved on the inside of the sealing ring, and the surface of the sealing ring is also sealingly and slidingly connected to a fixing member fixedly connected to the shell; a connecting member is threadedly connected to the surface of the silicone button, the bottom of the connecting member is fixedly connected to spring 1 through a spring fixing member, and the bottom end of the spring 1 is fixedly connected to a mainboard through a spring fixing member; a Hall element sleeved inside spring 1 is installed on the top of the mainboard, the top of the Hall element is fixedly connected to a trigger rod, the top of the trigger rod is provided with a movable block, and the top of the movable block is provided with spring 2.

[0005] By adopting the above technical solution, a sealing ring, a sealing groove and a silicone button are set, and a sealed sliding connection method is adopted. The silicone button completes the pressing of the Hall element, and the sealing ring always slides in a sealed manner inside the sealing groove, which can play a waterproof role; by setting a threaded connection between the silicone button and the connector, the silicone button can be removed and replaced separately; by setting a second spring, a movable block, a trigger rod and a Hall element, when the silicone button is pressed down, the compression and rebound of the second spring are used to push the trigger rod to squeeze the Hall element, thereby improving the sensitivity of the button.

[0006] The utility model is further configured as follows: a trigger block is fixedly connected to the bottom of the silicone button, and the trigger block is sleeved on the surface of the trigger rod.

[0007] By adopting the above technical solution, the trigger block is set to contact the Hall element. As the silicone button moves downward, the trigger block at the bottom of the silicone button contacts the top of the Hall element and presses the Hall element, so that the sealing groove can obtain trigger feedback from the silicone button.

[0008] The utility model is further configured as follows: the bottom end of the second spring is fixedly connected to the movable block through a spring fixing piece, and the top end of the second spring is fixedly connected to the silicone button through a spring fixing piece.

[0009] By adopting the above technical solution, through the setting of spring 2, the silicone button presses spring 2 downward, and spring 2 is subjected to force to generate a rebound force. The rebound force of spring 2 cannot rebound upward because the silicone button moves downward, while the rebound force of spring 2 can push the movable block to press the trigger rod downward, and the Hall element is pressed down by the trigger rod, so that the Hall element can be pressed when the slider is not in contact with the Hall element, which can improve the sensitivity of the button.

[0010] The utility model is further configured as follows: the surface of the movable block is fixedly connected to two sliding blocks, and the interior of the silicone button is provided with two sliding grooves which are slidably connected to the sliding blocks.

[0011] By adopting the above technical solution, the arrangement of the slider and the slide groove guides the up and down movement of the movable block, ensuring that the movable block can be in a straight line when moving up and down.

[0012] The utility model is further configured as follows: a receiving groove is provided inside the silicone button, and the movable block and the second spring are both located inside the receiving groove.

[0013] By adopting the above technical solution, through the setting of the storage groove, when the silicone button presses the spring 2 downward, the spring 2 is compressed in the storage groove to store the compressed spring 2, and the movable block can slide inside the storage groove.

[0014] The utility model is further configured as follows: the interior of the silica gel button and the trigger rod are sleeved, and the bottom of the movable block contacts the top of the trigger rod.

[0015] By adopting the above technical solution, when the silicone button and the trigger rod are sleeved and the silicone button is downward, the trigger rod will not affect the normal movement of the silicone button; the bottom of the movable block contacts the top of the trigger rod, and the silicone button is moved downward. The silicone button pushes the spring 2 downward to squeeze the trigger rod, and the trigger rod is subjected to force to resist the Hall element to complete the pressing of the Hall element.

[0016] In summary, the present invention has the following beneficial effects:

[0017] The utility model uses a sealing ring fixedly connected to the surface of the silicone key and sealed and slidably connected to the sealing groove. When the slider at the bottom of the silicone key and the Hall element are in contact and the trigger rod presses the Hall element under the rebound force of the second spring, the sealing ring is inside the sealing groove, thereby achieving a waterproof effect.

[0018] By setting a threaded connection between the silicone button and the connector, when the silicone button needs to be replaced, the silicone button and the connector can be separated by rotating the silicone button, making it easier to replace;

[0019] By setting spring 2 and the movable block inside the silicone button, and connecting the trigger rod and the Hall element; when the silicone button is pressed downward, force can be applied to spring 2, allowing spring 2 to generate a rebound force and apply it to the trigger rod. The rebound force given to the trigger rod by spring 2 allows the trigger rod to touch the Hall element, which can achieve early triggering of the Hall element and help improve the sensitivity of the button.

[0025] The present invention will be described in further detail below with reference to the accompanying drawings.

[0026] Example 1:

[0027] refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4, a waterproof silicone button for electronic products, including a shell 1, a sealing groove 2 is opened on the top of the shell 1, a sealing ring 3 is sealingly and slidingly connected inside the sealing groove 2, a silicone button 4 is fixedly sleeved inside the sealing ring 3, and the surface of the sealing ring 3 is also sealingly and slidingly connected to a fixing part 5 fixedly connected to the shell 1; a connecting part 6 is threadedly connected to the surface of the silicone button 4, the bottom of the connecting part 6 is fixedly connected to a spring 1 7 through a spring fixing part, and the bottom end of the spring 1 7 is fixedly connected to a main board 8 through a spring fixing part; a Hall element 9 is installed on the top of the main board 8 and is sleeved inside the spring 1 7. A trigger rod 10 is fixedly connected to the top of the Hall element 9, and a movable block 11 is provided on the top of the movable block 11. A spring 2 12 is provided on the top of the movable block 11; by fixing the sealing ring 3 on the surface of the silicone button 4 and sealing and slidingly connected to the sealing groove 2, when After the slider 13 at the bottom of the silicone button 4 completes contact with the Hall element 9 and after the trigger rod 10 presses the Hall element 9 under the rebound force of the spring 2 12, the sealing ring 3 is inside the sealing groove 2, so it can play a waterproof role; by setting the silicone button 4 and the connector 6 to be threaded, when the silicone button 4 needs to be replaced, the silicone button 4 and the connector 6 can be separated by rotating the silicone button 4, which is convenient for replacement; by setting the spring 2 12 and the movable block 11 inside the silicone button 4, the trigger rod 10 and the Hall element 9 are connected; when the silicone button 4 is downward, force can be applied to the spring 2 12, so that the spring 2 12 generates a rebound force and applies it to the trigger rod 10, and the trigger rod 10 is given a rebound force by the spring 2 12, so that the trigger rod 10 touches the Hall element 9, which can achieve early triggering of the Hall element 9, which is beneficial to improve the sensitivity of the button.

[0028] Furthermore, a trigger block 16 is fixedly connected to the bottom of the silicone button 4, and the trigger block 16 is sleeved on the surface of the trigger rod 10. Through the setting of the trigger block 16, it is used to contact the Hall element 9. As the silicone button 4 moves downward, the trigger block 16 at the bottom of the silicone button 4 contacts the top of the Hall element 9 and presses the Hall element 9, so that the sealing groove 2 can obtain the trigger feedback of the silicone button 4.

[0029] Furthermore, the bottom end of the spring 2 12 is fixedly connected to the movable block 11 through a spring fixing piece, and the top end of the spring 2 12 is fixedly connected to the silicone button 4 through a spring fixing piece. Through the setting of the spring 2 12, the silicone button 4 presses the spring 2 12 downward, and the spring 2 12 is forced to generate a rebound force. The rebound force of the spring 2 12 cannot rebound upward because the silicone button 4 moves downward, and the rebound force of the spring 2 12 can push the movable block 11 to press the trigger rod 10 downward, and the Hall element 9 is pressed down by the trigger rod 10, so that the Hall element 9 can be pressed when the slider 13 is not in contact with the Hall element 9, which can improve the sensitivity of the button.

[0030] Furthermore, two sliders 13 are fixedly connected to the surface of the movable block 11, and two sliding grooves 14 are provided inside the silicone button 4 and are slidably connected to the sliders 13. Through the setting of the sliders 13 and the sliding grooves 14, the up and down movement of the movable block 11 is guided, ensuring that the movable block 11 can be in a straight line when moving up and down.

[0031] Furthermore, a storage groove 15 is opened inside the silicone button 4, and the movable block 11 and the spring 2 12 are both located inside the storage groove 15. Through the setting of the storage groove 15, when the silicone button 4 presses the spring 2 12 downward, the spring 2 12 compresses the storage groove 15 to store the compressed spring 2 12, and to facilitate the sliding of the movable block 11 inside the storage groove 15.

[0032] Furthermore, the interior of the silicone button 4 and the trigger rod 10 are sleeved, and the bottom of the movable block 11 is in contact with the top of the trigger rod 10. When the silicone button 4 and the trigger rod 10 are sleeved and the silicone button 4 is downward, the trigger rod 10 will not affect the normal movement of the silicone button 4; the bottom of the movable block 11 is in contact with the top of the trigger rod 10, and through the silicone button 4 downward, the silicone button 4 pushes the spring 2 12 downward to squeeze the trigger rod 10, and the trigger rod 10 is forced to resist the Hall element 9 to complete the pressing of the Hall element 9.

[0033] Brief description of the usage process: During use, when the silicone button 4 is pressed downward by the user, the silicone button 4 drives the sealing ring 3 to slide and seal inside the sealing groove 2. When the trigger block 16 and the trigger rod 10 come into contact, the sealing ring 3 is still inside the sealing groove 2 and is still in a sealed sliding connection state.

[0034] When the silicone button 4 moves downward, it will press down the spring 2 12. The spring 2 12 is compressed to generate a rebound force. Since the silicone button 4 continues to move downward, the rebound force of the spring 2 12 can only act on the trigger rod 10. The trigger rod 10 will directly press the Hall element 9 downward. Therefore, when the silicone button 4 moves downward, the trigger rod 10 can trigger the Hall element 9 in advance under the action of the spring 2 12.

[0035] And because the silicone button 4 and the connector 6 are threadedly connected, when the silicone button 4 is downward, the connector 6 will also press the spring 1 7 downward, compressing the spring 1 7 until the slider 13 contacts the Hall element 9.

[0036] When the Hall element 9 is pressed, the sealing groove 2 receives the signal and executes it.

[0037] If you need to replace the silicone button 4, just rotate the silicone button 4 to separate the silicone button 4 and the connecting piece 6 and pull out the silicone button 4. Because the connecting piece 6 and the sealing groove 2 are connected by the spring fixing piece of the spring 1 7, the spring 1 7 cannot rotate and the connecting piece 6 cannot rotate.

[0038] To install the silicone button 4, you only need to slide the sealing ring 3 into the inside of the sealing groove 2, align the silicone button 4 and the connecting piece 6, and rotate the threads of the silicone button 4 and the connecting piece 6 to lock them.

[0039] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
