Description

Technical Field

[0001] This utility model relates to the field of electronic equipment technology, and in particular to a switching mechanism and an electronic device. Background Technology

[0002] In some equipment with high operational safety requirements, such as medical equipment or factory instruments, switches are often placed inside the equipment casing to prevent accidental triggering. Since the switch is built-in, it is necessary to indirectly control the internal tactile switch through an opening on the casing. Due to the influence of the overall structural size, the switch handle is often short, making it difficult for users to smoothly transmit the operating force to the switch inside the casing through a short stroke, resulting in insufficient pressing or inadequate triggering. Triggering the switch by inserting an external tool into the opening is also quite cumbersome. Utility Model Content

[0003] The main purpose of this invention is to propose a switching mechanism and electronic device, which aims to solve the technical problem that the switch inside the housing is not easy to trigger.

[0004] To achieve the above objectives, the present invention proposes a switching mechanism applied to an electronic device. The electronic device has a housing, an internal mounting cavity, and a through hole communicating with the inside and outside of the mounting cavity. The switching mechanism includes:

[0005] A touch switch is located within the mounting cavity;

[0006] A push rod is slidably disposed in the through hole, with one end of the push rod exposed at the mounting cavity and the other end located within the mounting cavity and extending toward the tactile switch; and

[0007] A reset structure is provided within the mounting cavity and elastically connects the push rod and the outer shell.

[0008] In one embodiment, the reset structure includes a spring sleeved around the outer periphery of the push rod and elastically connected to the push rod, such that the spring is compressed when the push rod is pushed toward the mounting cavity.

[0009] In one embodiment, the switching mechanism further includes a mounting bracket, which is vertically disposed on the inner wall of the mounting cavity. The mounting bracket is spaced apart from the tactile switch and is close to the inner wall of the housing. The spring is disposed between the mounting bracket and the inner wall of the housing, and its two ends are elastically connected to the push rod and the mounting bracket, respectively. One end of the push rod in the mounting cavity passes through the spring and the mounting bracket in sequence to cooperate with the tactile switch.

[0010] In one embodiment, the mounting bracket has a mounting hole, one end of the push rod passes through the mounting hole and extends toward the tactile switch, and the push rod is configured as a limiting portion on the side of the mounting bracket facing the tactile switch, the outer diameter of the limiting portion being larger than the diameter of the mounting hole.

[0011] In one embodiment, a limiting protrusion is provided on the outer periphery of the end of the push rod away from the tactile switch, the outer diameter of the limiting protrusion is larger than the outer diameter of the push rod, and the spring is disposed between the limiting protrusion and the mounting bracket.

[0012] In one embodiment, the reset structure further includes a sleeve fitted around the outer periphery of the spring. One end of the sleeve is fixedly mounted on the side of the mounting bracket away from the tactile switch, and the other end extends toward the inner wall of the housing to the limiting protrusion.

[0013] In one embodiment, a retaining edge is provided on the inner wall of one end of the sleeve near the mounting bracket. The retaining edge extends radially inward along the sleeve, and one end of the spring is elastically connected to the retaining edge.

[0014] In one embodiment, the switching mechanism further includes a support frame disposed on the inner wall of the mounting cavity and spaced apart from the mounting frame. The support frame has a guide hole, the inner wall of which is fitted against the outer wall of the limiting protrusion.

[0015] In one embodiment, the switching mechanism further includes a circuit board disposed within the mounting cavity, and the tactile switch is electrically connected to the circuit board;

[0016] And / or, multiple tactile switches are provided, each tactile switch is provided with a push rod and a reset structure, and multiple through holes are provided on the housing, with each push rod slidably disposed in one of the through holes.

[0017] This invention also proposes an electronic device, including a switching mechanism as described in any of the preceding claims.

[0018] In this invention, the switching mechanism is housed within the mounting cavity formed by the electronic device's housing. A tactile switch with control function is installed inside. A through hole is provided on one side of the housing. A push rod and a reset mechanism are positioned between the tactile switch and the through hole. One end of the push rod is exposed at the through hole, while the other end extends towards the tactile switch, allowing the user to push and press the push rod inwards at the through hole, pushing it towards the tactile switch and causing it to contact the switch, thus opening or closing the tactile switch. The end of the push rod furthest from the tactile switch is located at the through hole. The push rod does not protrude from the outer wall of the housing to avoid accidental activation and potential safety hazards. In addition, a reset mechanism is provided inside the housing. After pressing the push rod into the mounting cavity, releasing the push rod will allow the reset mechanism to push the push rod away from the tactile switch without external force, thus returning the push rod to its original position for easy re-pressing. Compared to using an external object to reach into the housing and contact the tactile switch, which is difficult to operate and requires additional tools, the push rod and reset mechanism make pressing the tactile switch more convenient while avoiding accidental activation.

[0034] In some equipment with high operational safety requirements, such as medical equipment or factory instruments, switches are often placed inside the equipment casing to prevent accidental triggering. Since the switch is built-in, it is necessary to indirectly control the internal tactile switch through an opening on the casing. Due to the influence of the overall structural size, the switch handle is often short, making it difficult for users to smoothly transmit the operating force to the switch inside the casing through a short stroke, resulting in insufficient pressing or inadequate triggering. Triggering the switch by inserting an external tool into the opening is also quite cumbersome.

[0035] This utility model proposes a switching mechanism and an electronic device.

[0036] Please see Figure 1In one embodiment of this utility model, the switching mechanism is applied to an electronic device. The electronic device has a housing 100, an internal mounting cavity is formed inside the housing 100, and the housing 100 has a through hole 110 communicating with the inside and outside of the mounting cavity. The switching mechanism includes:

[0037] The tactile switch 500 is located inside the mounting cavity;

[0038] A push rod 200 is slidably disposed in the through hole 110, with one end of the push rod 200 exposed at the mounting cavity and the other end located within the mounting cavity and extending toward the tactile switch 500; and

[0039] The reset structure 300 is located inside the mounting cavity and elastically connects the push rod 200 and the housing 100.

[0040] In this invention, the switching mechanism is housed within the mounting cavity formed by the electronic device housing 100. A tactile switch 500 with control function is installed inside. A through hole 110 is provided on one side of the housing 100. A push rod 200 and a reset mechanism are disposed between the tactile switch 500 and the through hole 110. One end of the push rod 200 is exposed at the through hole 110, and the other end extends towards the tactile switch 500. This allows the user to push and press the push rod 200 inward at the through hole 110, pushing it towards the tactile switch 500, causing the push rod 200 to contact the tactile switch 500, thus opening or closing the tactile switch 500. The push rod 200 is positioned away from the tactile switch 500. One end of the push rod does not protrude from the outer wall of the housing 100 at the through hole 110 to avoid accidental contact and potential safety hazards. In addition, a reset mechanism is provided inside the housing 100. After the push rod 200 is pressed into the mounting cavity, the push rod 200 is released. Without external force, the reset mechanism can push the push rod 200 away from the tactile switch 500, so that the push rod 200 returns to its original position, making it easier to push the push rod 200 again. Compared with using a foreign object to reach into the housing 100 to contact the tactile switch 500, which is not easy to operate and requires additional tools, the push rod 200 and the reset mechanism 300 make pressing the tactile switch 500 more convenient while avoiding accidental contact.

[0041] Specifically, this switching mechanism is used in electronic devices, such as factory workshop equipment or kitchen appliances, etc., without specific limitations. The tactile switch 500 is located inside the housing 100 and can be used to control the power on / off of electronic devices or to perform other functions, such as "confirmation" function, "mode switching" function, and "emergency stop" function. Detailed explanations will not be provided here. The tactile switch 500 is located inside the housing 100 to prevent accidental contact. The push rod 200 is configured to have a certain length, and its length, shape, and material are not limited. The two ends of the push rod 200 are configured as a force-applying end and a drive end. The drive end is close to the tactile switch 500, and the force-applying end extends toward the through hole 110 and is exposed at the through hole 110, but does not protrude beyond the through hole 110. Pressing the force-applying end inward at the through hole 110 causes the drive end to face the tactile switch 500.

[0042] In an embodiment of this utility model, the reset structure 300 includes a spring 310, which is sleeved on the outer periphery of the push rod 200 and elastically connected to the push rod 200 so that the spring 310 is compressed when the push rod 200 is pushed toward the mounting cavity.

[0043] like Figure 2 As shown, spring 310 is used to connect housing 100 and push rod 200. When push rod 200 is pushed toward the mounting cavity, push rod 200 triggers tactile switch 500, spring 310 is compressed. At this time, spring 310 has the tendency to drive push rod 200 toward through hole 110. After the external force on push rod 200 is released, spring 310 rebounds and push rod 200 back to its original position, so that push rod 200 can be pushed at through hole 110 to trigger tactile switch 500 next time.

[0044] In an embodiment of this utility model, the switch mechanism further includes a mounting bracket 600, which is vertically disposed on the inner wall of the mounting cavity. The mounting bracket 600 is spaced apart from the tactile switch 500 and is close to the inner wall of the housing 100. A spring 310 is disposed between the mounting bracket 600 and the inner wall of the housing 100, and its two ends are elastically connected to the push rod 200 and the mounting bracket 600, respectively. One end of the push rod 200 in the mounting cavity passes through the spring 310 and the mounting bracket 600 in sequence to cooperate with the tactile switch 500.

[0045] Please refer to Figure 2A vertical mounting bracket 600 is provided inside the mounting cavity. The mounting bracket 600 is mounted on the inner wall of the housing 100 via a horizontal mounting plate. The mounting bracket 600 is spaced apart from the tactile switch 500 and is positioned between the tactile switch 500 and the through hole 110. The mounting bracket 600 serves as a support for the mounting reset structure 300. The push rod 200 extends from the through hole 110 toward the mounting cavity, passes through the mounting bracket 600, and protrudes from the side of the mounting bracket 600 facing the tactile switch 500. When the push rod 200 is pushed, it triggers the tactile switch 500. A spring 310 is positioned between the mounting bracket 600 and the inner wall of the housing 100 where the through hole 110 is located, and the spring 310 is sleeved on the push rod. The outer periphery of spring 200 is connected at both ends to push rod 200 and mounting bracket 600 respectively. Specifically, spring 310 and mounting bracket 600 can be in contact or glued, etc., which is not limited here. When push rod 200 is pushed into the mounting cavity, push rod 200 moves toward mounting bracket 600 until push rod 200 protrudes from mounting bracket 600 and contacts tactile switch 500 on the side away from through hole 110. At this time, spring 310 is compressed and spring 310 stores energy. After tactile switch 500 is triggered, the push on push rod 200 is released. Since mounting bracket 600 does not move, spring 310 rebounds and drives push rod 200 to move toward through hole 110. After spring 310 resets, push rod 200 returns to its original position.

[0046] In an embodiment of this utility model, the mounting bracket 600 has a mounting hole, one end of the push rod 200 passes through the mounting hole and extends toward the tactile switch 500, and the push rod 200 is configured as a limiting part 210 on the side of the mounting bracket 600 toward the tactile switch 500, the outer diameter of the limiting part 210 being larger than the diameter of the mounting hole.

[0047] Specifically, such as Figure 2 As shown, the diameter of the end of the limiting part 210 near the mounting bracket 600 is larger than the diameter of the mounting hole. When the spring 310 rebounds and drives the push rod 200 to move toward the through hole 110, the push rod 200 moves into place when the limiting part 210 contacts the mounting bracket 600. The setting of the limiting part 210 can also prevent the push rod 200 from moving in the direction of the through hole 110, causing it to disengage from the mounting bracket 600 and the through hole 110. The outer surface of the limiting part 210 is conical, and the diameter decreases from the end near the mounting hole to the end away from the mounting hole, which reduces production costs and can accurately trigger the tactile switch 500 when the push rod 200 is pushed.

[0048] Please refer to Figure 2In this embodiment of the present invention, a limiting protrusion 220 is provided on the outer periphery of the end of the push rod 200 away from the tactile switch 500. The outer diameter of the limiting protrusion 220 is larger than the outer diameter of the push rod 200. The spring 310 is disposed between the limiting protrusion 220 and the mounting bracket 600. Specifically, the limiting protrusion 220 is provided on the outer periphery of the end of the push rod 200 away from the tactile switch 500, which is the force-applying end. The limiting protrusion 220 is configured to provide a mounting position for the spring 310. When the spring 310 is pushed toward the mounting cavity, the limiting protrusion 220 presses against the spring 310, causing the spring 310 to compress. When the spring 310 rebounds, the spring 310 pushes the limiting protrusion 220 toward the through hole 110. The spring 310 and the limiting protrusion 220 can be elastically abutted or configured to be bonded, without limitation.

[0049] Please refer to Figure 2 In an embodiment of this utility model, the reset structure 300 further includes a sleeve 320. The sleeve 320 is sleeved on the outer periphery of the spring 310. One end of the sleeve 320 is fixedly installed on the side of the mounting bracket 600 away from the tactile switch 500, and the other end extends toward the inner wall of the housing 100 to the limiting protrusion 220. The sleeve 320 encloses the spring 310. When the push rod 200 is pushed and the spring 310 rebounds to push the reset, the sleeve 320 can prevent the spring 310 from shifting and affecting the compression and reset process.

[0050] In an embodiment of this utility model, a retaining edge is provided on the inner wall of the sleeve 320 near the mounting bracket 600. The retaining edge extends radially inward along the sleeve 320. One end of the spring 310 is elastically connected to the retaining edge. The retaining edge is mounted on the mounting bracket 600 to fix the sleeve 320. The inner diameter of the retaining edge is smaller than the inner diameter of the sleeve 320 and also smaller than the inner diameter of the spring 310, so that the spring 310 can be compressed and reset between the retaining edge and the limiting protrusion 220. The spring 310 and the retaining edge can be elastically connected or bonded.

[0051] In an embodiment of this utility model, the switching mechanism further includes a support frame 700, which is disposed on the inner wall of the mounting cavity and spaced apart from the mounting frame 600. The support frame 700 has a guide hole, the inner wall of which fits against the outer wall of the limiting protrusion 220, so that when the push rod 200 is pushed, the limiting protrusion 220 can slide within the guide hole, preventing the push rod 200 from being limited by the mounting hole and its end from being lowered due to gravity, making it inconvenient for the user to push the push rod 200 at the through hole 110. The support frame 700 and the guide hole ensure that the push rod 200 is always in a horizontal state, ensuring the stability of pushing the push rod 200.

[0052] In an embodiment of this utility model, the switching mechanism further includes a circuit board 400, which is disposed in the mounting cavity, and the tactile switch 500 is electrically connected to the circuit board 400.

[0053] In one embodiment, such as Figure 1 and Figure 2 As shown, multiple tactile switches 500 are provided, and each tactile switch 500 is provided with a push rod 200 and a reset structure 300. The housing 100 is provided with multiple through holes 110. Each push rod 200 is slidably disposed in a through hole 110. Each tactile switch 500 is connected to the circuit board 400 and can be configured with different functions, such as "power on", "power off", "pause", "reset", etc. By pushing different push rods 200, different tactile switches 500 are triggered to achieve different functions.

[0054] This utility model also proposes an electronic device, including a housing 100 and a switching mechanism. The specific structure of the switching mechanism is as described in the above embodiments. Since this electronic device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0055] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
