Description
Technical Field
[0001] This application relates to the field of switch control devices, and in particular to electronic switch control devices. Background Art
[0002] An electronic switch control device belongs to the category of electronic components. It refers to an electronic component that can open a circuit, interrupt the current, or make the current flow to other circuits. The most common switch is an electromechanical device operated by humans, which has one or several electronic contacts. The "closure" of the contact means that the electronic contact conducts and allows current to flow through; the "open circuit" of the switch means that the electronic contact does not conduct to form an open circuit and does not allow current to flow through. Among them, the tactile switch is widely used in people's daily lives.
[0003] The tactile switch is pressed to deform the internal metal elastic sheet, thereby connecting the circuit. After releasing the button, the metal elastic sheet will return to its original shape and drive the button to reset. At the same time, the tactile switch is also used in road traffic information base stations. At present, the tactile switch device often has problems such as switch rebound failure and internal structure instability leading to function failure.
[0004] In view of the above related technologies, the inventor proposes an electronic switch control device. Utility Model Content
[0005] In order to improve the stability and durability of the electronic control switch, this application provides an electronic switch control device.
[0006] The electronic switch control device provided by this application adopts the following technical solutions:
[0007] The electronic switch control device includes a mounting base, an upper cover is provided on the mounting base, a mounting cavity is provided on the mounting base, a slider is slidably provided on the upper cover, a pressing plate is provided at one end of the slider away from the upper cover, a sliding groove for slidably matching the slider is provided on the upper cover, an auxiliary pressing component for assisting in pressing the switch is provided in the mounting cavity, a metal elastic sheet is provided in the mounting cavity, a metal contact is provided at the center bottom of the mounting cavity, the metal contact is fixedly connected to the inner bottom surface of the mounting cavity, a plurality of metal pins are provided at the bottom of the mounting base, and a fixing component for fixing the upper cover is provided on the mounting base.
[0008] By adopting the above technical solution, the operator first installs the electronic switch control device in the road traffic information base station. Then, the operator fixes the upper cover on the mounting base through the fixing component. Next, the operator pushes the pressing plate, and the movement of the pressing plate drives the slider to slide in the sliding groove. Under the action of the auxiliary pressing component, the slider squeezes the incoming and outgoing elastic pieces, and the metal elastic piece deforms under the extrusion and contacts the metal contact, so as to achieve the purpose of changing the circuit connection state and improve the stability of the overall internal structure.
[0009] Preferably, the fixing component includes a fixing block slidably arranged on the mounting base and a fixing spring fixedly connected to the fixing block. A slope is arranged on the end face of the fixing block close to the upper cover. A fixing sliding groove for the sliding fit of the fixing block is arranged on the mounting base, and a plugging groove for the plugging fit of the fixing block is arranged on the upper cover.
[0010] By adopting the above technical solution, the operator first places the upper cover on the mounting base. Then, the operator pushes the upper cover, and the inner wall of the upper cover slides in cooperation with the outer wall of the mounting base. At this time, the fixing block moves in the fixing sliding groove under the action of the upper cover, and the fixing spring is in a compressed state. The operator continues to push the upper cover. When the plugging groove on the upper cover corresponds to the fixing block, at this time, the fixing block pops out of the fixing sliding groove under the action of the fixing spring, and the fixing block is in plugging fit with the plugging groove, which is convenient for the operator to lock the upper cover.
[0011] Preferably, the auxiliary pressing component includes a pushing plate arranged in the installation cavity, sliding blocks arranged on both sides of the pushing plate, and a pushing block arranged under the pushing plate. Auxiliary sliding grooves for the sliding fit of the sliding blocks are arranged on the inner side wall of the installation cavity, and one end of the pushing block far away from the pushing plate abuts against the metal elastic piece.
[0012] By adopting the above technical solution, the operator pushes the pressing plate, and the movement of the pressing plate drives the slider to move. The movement of the slider drives the pushing plate below to move. The movement of the pushing plate drives the sliding blocks on both sides and the pushing block below to move. The movement of the pushing block pushes the metal elastic piece to deform and contact the metal contact at the bottom of the installation cavity, so as to change the circuit connection state. The auxiliary pressing component further improves the stability of the internal structure of the electronic switch control device.
[0013] Preferably, a reset spring is arranged under each sliding block. The reset spring is fixedly connected to the sliding block, and one end of the reset spring far away from the fixing block is fixedly connected to the inner wall of the auxiliary sliding groove.
[0014] By adopting the above technical solution, the operator drives the push plate to slide downward through the slider. The sliding of the push plate drives the sliding blocks on both sides and the push block below to move downward. At this time, the return spring is in a compressed state. The movement of the push block causes the metal elastic sheet to deform and contact the metal contact at the bottom of the installation cavity, thereby changing the circuit connection state. The sliding block drives the push plate to move back through the return spring to reset the push plate.
[0015] Preferably, the push block abuts against the center point of the metal elastic sheet.
[0016] By adopting the above technical solution, the push block abutting against the center point of the metal elastic sheet makes it more convenient for the operator to touch the metal contact at the bottom of the installation cavity when pushing the pressing plate.
[0017] Preferably, a rubber pad is arranged below the push block. The rubber pad is fixedly connected to the push block, and the end face of the rubber pad away from the push block is attached to the metal elastic sheet.
[0018] By adopting the above technical solution, the setting of the rubber pad can buffer the pressure between the push block and the metal elastic sheet, and avoid damage to the metal elastic sheet caused by excessive pushing force.
[0019] Preferably, a metal gasket is arranged below the metal elastic sheet.
[0020] By adopting the above technical solution, the setting of the metal gasket makes the metal elastic sheet more stable, and at the same time provides the necessary space for the metal contact below.
[0021] Preferably, an anti - detachment plate is arranged on the side of the slider close to the push plate. The anti - detachment plate is fixedly connected to the slider, and one end of the anti - detachment plate away from the slider abuts against the push plate.
[0022] By adopting the above technical solution, the setting of the anti - detachment plate can effectively prevent the sliding block from over - rebounding under the action of the return spring, thereby causing the slider to slide out of the installation cavity and making the overall device more stable.
[0023] Preferably, a sealing strip is arranged on the outer peripheral surface of the switch housing.
[0024] By adopting the above technical solution, the setting of the sealing strip can make the device more tightly and stably installed during installation, and can improve the overall stability of the device.
[0025] In summary, the present application includes at least one of the following beneficial technical effects:
[0026] 1. The operator first installs the electronic switch control device in the road traffic information base station. Then, the operator fixes the upper cover on the mounting base through the fixing component. Next, the operator pushes the pressing plate. The movement of the pressing plate drives the slider to slide in the sliding groove. Under the action of the auxiliary pressing component, the slider squeezes the incoming and outgoing elastic pieces. The metal elastic piece deforms under the extrusion and contacts the metal contact, so as to achieve the purpose of changing the circuit connection state and improve the stability of the overall internal structure.
[0027] 2. The operator first places the upper cover on the mounting base. Then, the operator pushes the upper cover. The inner wall of the upper cover slides cooperatively with the outer wall of the mounting base. At this time, the fixing block moves in the fixing chute under the action of the upper cover, and the fixing spring is in a compressed state. The operator continues to push the upper cover. When the insertion slot on the upper cover corresponds to the fixing block, at this time, the fixing block pops out of the fixing chute under the action of the fixing spring, and the fixing block is inserted and cooperated with the insertion slot, which is convenient for the operator to lock the upper cover.
[0028] 3. The operator pushes the pressing plate. The movement of the pressing plate drives the slider to move. The movement of the slider drives the pushing plate below to move. The movement of the pushing plate drives the sliding blocks on both sides and the pushing block below to move. The movement of the pushing block pushes the metal elastic piece to deform and contact the metal contact at the bottom of the installation cavity, so as to change the circuit connection state. The auxiliary pressing component further improves the stability of the internal structure of the electronic switch control device. Brief Description of the Drawings

[0034] The following is combined with the attached Figures 1-3A further detailed description of the present application is provided.
[0035] The embodiment of the present application discloses an electronic switch control device. Referring to Figure 1 , the electronic switch control device includes a mounting base 1. The mounting base 1 is in the shape of a rectangular block and is horizontally arranged. An upper cover 2 is provided on the mounting base 1. The upper cover 2 is a rectangular box with an open bottom, and the inner wall of the upper cover 2 abuts against the outer wall of the mounting base 1. A sealing strip 8 is provided on the outer peripheral surface of the bottom of the mounting base 1. The sealing strip 8 is horizontally arranged and is fixedly connected to the mounting base 1. A plurality of metal contacts 7 are provided at the bottom of the mounting base 1. The metal contacts 7 are vertically arranged and are fixedly connected to the mounting base 1. A slider 21 is provided on the upper cover 2. The slider 21 is in the shape of a rectangular block and is vertically arranged. The slider 21 is slidably connected to the upper cover 2. A pressing plate 22 is provided on the slider 21. The pressing plate 22 is in the shape of a rectangular plate and is horizontally arranged. The pressing plate 22 is fixedly connected to the slider 21.
[0036] Referring to Figure 2 , an installation cavity 11 is formed in the mounting base 1. An auxiliary pressing assembly 3 is arranged in the installation cavity 11. The auxiliary pressing assembly 3 includes a pushing plate 31, a sliding block 32, and a pushing block 33. The pushing plate 31 is in the shape of a rectangular plate and is horizontally arranged. There are two sliding blocks 32. The sliding blocks 32 are in the shape of rectangular blocks and are horizontally arranged. The sliding blocks 32 are fixedly connected to the pushing plate 31. The pushing block 33 is in the shape of a rectangular block and is vertically arranged. The pushing block 33 is fixedly connected to the pushing plate 31. Auxiliary sliding grooves 34 are formed on the inner wall of the mounting base 1. The outer wall of the sliding block 32 is slidably engaged with the inner wall of the auxiliary sliding groove 34. A return spring 321 is arranged below the sliding block 32. The return spring 321 is vertically arranged. One end of the return spring 321 is fixedly connected to the sliding block 32, and the other end is fixedly connected to the inner wall of the auxiliary sliding groove 34. The setting of the sealing strip 8 can make the installation of the device more compact and improve the overall stability of the device.
[0037] Referring to Figure 2 , a rubber pad 331 is arranged below the pushing block 33. The rubber pad 331 is horizontally arranged and is fixedly connected to the pushing block 33. A metal elastic sheet 5 is arranged below the rubber pad 331. The metal elastic sheet 5 is horizontally arranged, and the upper surface of the metal elastic sheet 5 is attached to the lower surface of the rubber pad 331. An anti - detachment plate 24 is arranged on one side of the slider 21 close to the pushing plate 31. The anti - detachment plate 24 is in the shape of a rectangular plate and is horizontally arranged. The anti - detachment plate 24 is fixedly connected to the slider 21. The end surface of the anti - detachment plate 24 away from the slider 21 abuts against the pushing plate 31. A metal contact 6 is arranged on the inner bottom surface of the installation cavity 11. The metal contact 6 is vertically arranged and is fixedly connected to the installation cavity 11. A metal gasket 51 is arranged below the metal elastic sheet 5. The metal gasket 51 is in the shape of a rectangular sheet and is fixedly connected to the bottom of the installation cavity 11.
[0038] The operator pushes the pressing plate 22. The movement of the pressing plate 22 drives the slider 21 to move downward. The slider 21 drives the pushing block to move downward through the pushing plate. At this time, the return spring 321 is in a compressed state, and the sliding block 32 also moves downward together with the pushing plate, thereby driving the rubber pad 331 to squeeze the metal elastic sheet 5 to deform. When the metal elastic sheet 5 deforms and contacts the metal contact 6, the connection state of the circuit is changed. Then the operator stops pushing the pressing plate 22, and the pushing plate rebounds under the combined action of the return spring 321 and the metal elastic sheet 5, and the metal elastic sheet 5 and the return spring 321 return to their original states.
[0039] The anti - detachment plate 24 can prevent the slider 21 from detaching from the installation cavity 11. The metal gasket 51 below the metal elastic sheet 5 increases the deformation space of the metal elastic sheet 5 and also increases the contact space of the metal contact 6 below. The rubber pad 331 plays a role in protecting the metal elastic sheet 5, avoiding irreversible deformation of the metal elastic sheet 5, and improving the stability of the switch control device.
[0040] Refer to Figure 3 As shown in the figure, a fixing component 4 for fixing the upper cover 2 is provided on the outer wall of the installation base 1. The fixing component 4 includes a fixing block 41 and a fixing spring 42. The fixing block 41 is a rectangular block. The fixing block 41 is horizontally arranged and slidably penetrates through the outer wall of the installation base 1. A fixing chute 43 is formed on the installation base 1. The outer wall of the fixing block 41 is slidably matched with the inner wall of the fixing chute 43. The fixing spring 42 is horizontally arranged. One end of the fixing spring 42 is fixedly connected to the fixing block 41, and the other end is fixedly connected to the inner wall of the fixing chute 43. A plug - in groove 23 is formed on the upper cover 2. The outer wall of the fixing block 41 is slidably matched with the inner wall of the plug - in groove 23.
[0041] The operator places the upper cover 2 on the installation base 1, and then the operator pushes the upper cover 2. The inner wall of the upper cover 2 is slidably matched with the outer wall of the installation base 1. At this time, the fixing block 41 moves in the fixing chute 43 under the action of the upper cover 2, and the fixing spring 42 is in a compressed state. The operator continues to push the upper cover 2. When the plug - in groove 23 on the upper cover 2 corresponds to the fixing block 41, at this time, the fixing block 41 pops out of the fixing chute 43 under the action of the fixing spring 42, and the fixing block 41 is in plug - in fit with the plug - in groove 23. The setting of the fixing component 4 facilitates the operator to quickly install and fix the upper cover 2.
[0042] The implementation principle of the electronic switch control device in the embodiment of the present application is as follows: The operator installs the switch control device in the road traffic information base station. Then, the operator places the upper cover 2 on the installation base 1. Next, the operator pushes the upper cover 2. At this time, the fixing block 41 moves in the fixing chute 43 under the action of the upper cover 2, and the fixing spring 42 is in a compressed state. The operator continues to push the upper cover 2. When the insertion slot 23 matches the fixing block 41, the fixing block 41 pops out of the fixing chute 43 under the action of the fixing spring 42, and the fixing block 41 is inserted and matched with the insertion slot 23 to complete the fixation of the upper cover 2.
[0043] The operator pushes the pressing plate 22. The movement of the pressing plate 22 drives the slider 21 to slide in the sliding groove 211. The slider 21 drives the pushing block to move downward through the pushing plate. The sliding block 32 also moves downward in the auxiliary chute 34 together with the pushing plate. At this time, the return spring 321 is in a compressed state, thereby driving the rubber pad 331 to squeeze the metal elastic sheet 5 to deform. When the metal elastic sheet 5 deforms and contacts the metal contact 6, the connection state of the circuit is changed. Then the operator stops pushing the pressing plate 22, and the pushing plate rebounds under the combined action of the return spring 321 and the metal elastic sheet 5, and the metal elastic sheet 5 and the return spring 321 return to their original states.
[0044] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
