Description

Technical Field

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

[0002] The opening structure of related video recording devices mainly consists of two schemes. The first scheme mainly comprises a main unit housing, a video push button limiting bracket (metal part), a video push button (metal + plastic part), and a video push button cover. The metal part of the video push button body insert deforms, thus locking onto the video push button limiting bracket (metal part) fixed on the main unit housing, achieving the purpose of limiting the video push button. To ensure smooth sliding, dry film lubricant is usually added to the V-shaped protrusions on both sides.

[0003] The second design's opening structure mainly consists of a main unit housing, a recording push button, and a recording push button cover. Multiple protruding structures are provided on both sides of the main unit housing and the recording push button. When the recording push button slides, the side wall of the recording push button deforms to lock it in place, thus achieving the recording limit function. To reduce wear between the plastic structures, a dry film lubricant is added near the side walls of the recording push button to reduce the coefficient of friction.

[0004] The above-mentioned technical solutions have the following drawbacks: sliding friction is affected by material properties, metal video recording push button structures have adhesive wear, and plastic video recording push button structures wear out quickly, ultimately limiting their lifespan and tactile feel. In addition, both require the addition of dry film lubricant as auxiliary lubrication, which increases the process and labor costs. Utility Model Content

The terms "first," "second," "third," etc., are only for the convenience of describing this technical solution and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first," "second," "third," etc., may explicitly or implicitly include one or more of that feature. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0030] In the following description, specific details such as particular system structures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of the present invention. However, those skilled in the art will understand that the present invention can be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0031] This utility model discloses an electronic device, including a push button structure. The electronic device may be, but is not limited to, a law enforcement recorder. The push button structure may be, but is not limited to, a video recording push button structure.

[0032] See Figures 1 to 7 This utility model discloses a push button structure, including a main body shell 10, a push button 20, and a ball 30. The main body shell 10 is provided with a push button groove 11, and balls 30 are respectively provided on opposite sides of the middle of the push button groove 11 along the length direction. The push button 20 is movably installed in the push button groove 11. The push button 20 includes a push button body 21. The push button body 21 is provided with a first set of recesses 22 and a second set of recesses 23 on a first side and a second side along the length direction, respectively. The first set of recesses 22 and the second set of recesses 23 are spaced apart along the length direction of the push button body 21.

[0033] The push button structure has a closed state and an open state. When the push button structure is in the closed state, the ball 30 is located within the first set of recesses 22 (e.g., Figure 5 (as shown); when the push button structure is in the open state, the ball 30 is located within the second set of recesses 23 (as shown). Figure 6 (As shown).

[0034] In some embodiments, when there are multiple spheres 30, the number of recesses can be one more than the number of spheres. Of course, the number of spheres 30 and the number of recesses can be selected and set according to actual needs, and no specific limitation is made here.

[0035] like Figures 1 to 4 As shown, in some embodiments, the push button body 21 is provided with a first through hole 211 and a second through hole 212. Both the first through hole 211 and the second through hole 212 extend along the length of the push button body 21, with the first through hole 211 located near the first side and the second through hole 212 located near the second side. The provision of the first through hole 211 and the second through hole 212 allows the first and second sides of the push button body 21 to respectively form a first elastic arm and a second elastic arm. When the first and second sides of the push button body 21 contact the ball 30, the first and second elastic arms can be deformed towards the center of the push button body 21. The first through hole 211 and the second through hole 212 can be elongated holes, such as oblong holes. Of course, the first through hole 211 and the second through hole 212 can also be curved holes or other discontinuous through holes. The shapes of the first through hole 211 and the second through hole 212 can be selected and set according to actual needs, as long as the first side and the second side have space to deform toward the center of the push button body 21, so as to obtain the first elastic arm and the second elastic arm.

[0036] Combination Figures 5 to 7 As shown, in some embodiments, the first set of recesses 22 includes a first groove 221 on the first side and a second groove 222 on the second side. The line connecting the first groove 221 and the second groove 222 is a first connecting line a, which is perpendicular to the length direction of the push button body 21. Of course, the first groove 221 and the second groove 222 can also be offset along the length direction of the push button body 21, that is, the first connecting line a can be intersected with the length direction of the push button body 21.

[0037] The second set of recesses 23 includes a third groove 231 on the first side and a fourth groove 232 on the second side. The line connecting the third groove 231 and the fourth groove 232 is a second connecting line b. The second connecting line b is perpendicular to the length direction of the push button body 21. Of course, the third groove 231 and the fourth groove 232 can also be offset along the length direction of the push button body 21, that is, the second connecting line b can be intersected with the length direction of the push button body 21.

[0038] The first connecting line a and the second connecting line b both pass through the first through hole 211 and the second through hole 212, so that when the push button 20 moves, the first groove 221 and the second groove 222 have a certain elastic space when they cooperate with the ball 30. Similarly, the third groove 231 and the fourth groove 232 have a certain elastic space when they cooperate.

[0039] See Figures 1 to 4 In some embodiments, the push button 20 may further include an operating portion 24 disposed on the upper surface of the push button body 21, which can be used by an operator to push it with their fingers. The operating portion 24 may have concave-convex structures 25 on both sides along the direction of movement, which can increase roughness to improve friction. The push button 20 may be made of plastic. Of course, the push button 20 can also be made of suitable materials according to actual needs; no specific limitations are made here.

[0040] See Figure 4 In some embodiments, the push button 20 may also be provided with a magnetic suction member 26, which may be embedded in the push button body 21 to cooperate with the Hall device in the main housing 10. The movement of the push button 20 causes the magnetic suction member 26 to move closer to or further away from the Hall device, thereby controlling the high and low potential switching of the Hall device through the change of magnetic field, achieving the purpose of controlling the opening or closing of electronics (such as a video recorder), thus realizing the function of turning on and off recording.

[0041] See Figures 1 to 4 The inner side of the push button groove 11 is recessed outward to form a limiting groove 111. At least a portion of the structure of the ball 30 is located within the limiting groove 111, and at least a portion of the structure of the ball 30 protrudes from the limiting groove 111. Preferably, the limiting groove 111 can be an arc-shaped limiting groove.

[0042] In some embodiments, the diameter of the sphere 30 is 1-2 mm, which reduces the limitation of the sphere 30 on the overall structural size, allowing for miniaturization of the push button structure and consequently, miniaturization of the overall electronic device structure. Of course, the diameter of the sphere 30 can be adjusted appropriately according to actual needs, and no specific limitation is made here.

[0043] like Figure 8 As shown, in some embodiments, the height value X1 of the active space of the sphere 30 is less than the height value X2 of the push button body 21, thereby limiting the movement of the sphere 30 in the height direction.

[0044] In some embodiments, the sphere 30 comprises steel balls, such as, but not limited to, stainless steel balls or aluminum alloy balls. Of course, in some embodiments, the sphere 30 may also be made of non-metallic materials. For example, the sphere 30 may be made of rigid insulating materials, such as phenolic plastics, polyurethane plastics, epoxy plastics, unsaturated polyester plastics, furan plastics, silicone resins, acrylic resins, and their modified resins. Naturally, the materials used to prepare the sphere 30 can be selected and set according to actual needs, and no specific limitations are made here.

[0045] In some embodiments, the push button structure includes a push button cover 40 mounted on the main housing 10. The push button cover 40 may be detachably connected to the main housing 10, and the push button cover 40 is used to confine the ball 30 and the push button 20 within the push button groove 11. Further, the push button cover 40 may be provided with a through hole 41 to expose the operating part 24 of the push button 20.

[0046] In some embodiments, the push button structure is implemented as follows:

[0047] like Figure 5 As shown, in the initial position of the push button 20, i.e., the closed state, the ball 30 is limited to the first set of recesses 22. The ball 30 is in a pre-compression state (or zero-fit state, or very small interference state), ensuring that there is a certain resistance when moving between the recording on and off positions, providing a good feel, and limiting the ball 30 so that it is not easy to wobble. When the push button 20 moves to the left, the push button 20 and the ball 30 roll. During the movement of the push button 20, the interference between the first elastic arm and the second elastic arm and the ball 30 begins to increase, and the first elastic arm and the second elastic arm deform towards the middle of the push button body 21. When the push button 20 reaches the second set of recesses 23, it is in the open state, and the law enforcement recorder starts recording. Figure 6 Schematic diagram.

[0048] After multiple comparative tests, the results are as follows: The original push switch using the sliding friction method has a lifespan of about 30,000 cycles, and the feel (which can be measured by the pushing force of the toggle switch) is greatly reduced after 30,000 cycles; the push switch structure of this application can increase the lifespan to more than 60,000 cycles, and the feel is reduced by about 30%, effectively improving the lifespan and feel of the push switch structure.

[0049] Understandably, the push button 20 and the main housing 10 of this push button structure employ rolling friction, which effectively improves the lifespan and feel of the push button structure. Furthermore, this push button structure effectively reduces the number of parts (compared to the first solution in related technologies) and eliminates the need for dry film lubricant (compared to the second solution in related technologies), resulting in significantly lower costs. Additionally, it reduces assembly steps, enabling automated production.

[0050] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention.

[0051] It is understood that the above embodiments only illustrate preferred embodiments of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present utility model patent. It should be noted that for those skilled in the art, the above technical features can be freely combined, and several modifications and improvements can be made without departing from the concept of the present utility model, all of which fall within the protection scope of the present utility model.
