Description

Technical Field

[0001] The utility model relates to the technical field of law enforcement recorders, in particular to a switch structure of a law enforcement recorder. Background Art

[0002] A law enforcement recorder is a portable device that integrates digital video, digital photography, and an intercom transmitter. It's primarily used by law enforcement agencies to record and monitor law enforcement. The switch on the recorder controls the power and screen. Using the switch button, you can turn the recorder on and off, entering or exiting operation. Specific button combinations also allow you to directly enter specific functional modes.

[0003] However, the switch structure of existing law enforcement recorders is usually a button switch and a touch switch. During the law enforcement process, law enforcement officers usually wear the law enforcement recorders on their bodies, and other parts of the body may accidentally touch the button switch or touch switch, causing misoperation, resulting in the law enforcement recorder being turned on or off or switching functions by mistake, which not only affects the continuity of the recording, but may also miss important law enforcement moments. Utility Model Content

[0004] (1) Technical problems solved

[0005] In response to the deficiencies of the prior art, the present invention provides a switch structure for a law enforcement recorder, which can solve the problem that the switch structure of the existing law enforcement recorder is prone to misoperation, resulting in the law enforcement recorder being mistakenly turned on and off or switching functions, thereby affecting the continuity of the recording and missing important law enforcement moments. It can not only avoid misoperation of the switch structure during the use of the law enforcement recorder, but also improve the waterproof performance of the switch structure.

[0006] (2) Technical solution

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a switch structure of a law enforcement recorder, comprising a shell, a mounting groove being provided on one side of the shell, a waterproof silicone keycap being provided inside the mounting groove, a key connector being provided on one side of the waterproof silicone keycap, the other end of the key connector being connected to a fixed plate, a sliding pad being provided on the other side of the fixed plate, a limit plate being provided on the other side of the sliding pad, a sliding key being fixedly connected to the other side of the limit plate, and a fixed cover being installed on the outside of the shell.

[0008] Through the above technical solution, pushing the sliding key can cause the limit plate fixed to it to move horizontally. When the limit plate moves to the appropriate position, it will cause the fixed plate to move, and then the fixed plate pushes the waterproof silicone keycap through the key connector, thereby controlling the opening and closing of the law enforcement recorder.

[0009] Furthermore, a groove is provided inside the waterproof silicone keycap, and a card slot is provided on one side of the fixing plate. The card slot is a truncated cone structure. The length of the key connector is greater than the depth of the groove and the card slot. One end of the key connector is located inside the groove, and the other end of the key connector is located inside the card slot.

[0010] Through the above technical solution, the groove and the card slot can limit the movement of the key connector, so that the key connector moves linearly along the center connection line of the groove and the card slot, and when the fixed plate is subjected to thrust, it will push the waterproof silicone keycap through the key connector. When the thrust applied to the fixed plate disappears, the key connector will push the fixed plate to move in the opposite direction for reset.

[0011] Furthermore, a first protrusion is fixedly connected to one side of the fixed plate. The first protrusion is composed of a truncated cone-shaped block and a quadrilateral block. A through hole is opened inside the sliding pad, and the first protrusion passes through the through hole.

[0012] Through the above technical solution, the limiting plate can move horizontally and linearly, thereby driving the fixed plate to move horizontally and linearly in a direction perpendicular to the movement direction of the limiting plate.

[0013] Furthermore, a second protrusion is fixedly connected to one side of the limiting plate. The second protrusion is composed of a cylinder and a trapezoidal block. The slope of the inclined outer surface of the second protrusion is equal to the slope of the inclined outer surface of the first protrusion.

[0014] Through the above technical solution, since the slope of the inclined outer surface of the second protrusion is equal to the slope of the inclined outer surface of the first protrusion, it is convenient for the limiting plate to drive the second protrusion to move horizontally and linearly on one side of the first protrusion, and the first protrusion can be prevented from obstructing the horizontal linear movement of the second protrusion.

[0015] Furthermore, a through opening is provided inside the fixed cover plate, and a limiting groove is provided on the inner side of the fixed cover plate.

[0016] Through the above technical solution, the sliding key can pass through the through opening and be exposed on the outside of the fixed cover plate, making it convenient for the user to push the sliding key.

[0017] Furthermore, the limiting plate is located inside the limiting groove, and the sliding key passes through the opening.

[0018] Through the above technical solution, pushing the sliding key on the outer side of the fixed cover plate can drive the limiting plate to move inside the limiting groove.

[0019] Furthermore, both sides of the limiting plate are of uneven structure, the limiting plate and the limiting groove are connected in a sliding manner, and the length of the limiting plate is smaller than the length of the limiting groove.

[0020] Through the above technical solution, the limit plate is made of elastic material. Since the limit plate fits tightly with the limit groove, sufficient thrust is required when pushing the sliding key connected to the limit plate to prevent the limit plate from sliding randomly, which is helpful to prevent misoperation of the switch structure.

[0021] Furthermore, the length of the sliding pad is greater than the length of the limiting plate, and the length of the through hole is greater than the length of the first protrusion.

[0022] Through the above technical solution, the sliding pad is arranged between the fixed plate and the limit plate, and the sliding pad is tightly fitted with the fixed cover plate. The sliding pad can prevent moisture from entering the interior of the shell, thereby improving the waterproof performance of the switch structure.

[0023] Compared with the prior art, the present invention provides a switch structure for a law enforcement recorder, which has the following beneficial effects:

[0024] In the present invention, by pushing the sliding key to make it located at different positions, the opening and closing of the law enforcement recorder can be controlled. Since the two sides of the limit plate are uneven, and the limit plate is made of elastic material, and the limit plate is tightly fitted with the limit groove, sufficient thrust is required when pushing the sliding key connected to the limit plate to prevent the limit plate from sliding at will, which is beneficial to prevent misoperation of the switch structure. In addition, the sliding pad is arranged between the fixed plate and the limit plate, and the sliding pad is tightly fitted with the fixed cover plate. The sliding pad can prevent moisture from entering the inside of the shell, thereby improving the waterproof performance of the switch structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] See also Figures 1-6 The utility model provides a technical solution: a switch structure of a law enforcement recorder, including a shell 1, a mounting groove 2 is opened on one side of the shell 1, a waterproof silicone keycap 3 is arranged inside the mounting groove 2, a key connector 5 is arranged on one side of the waterproof silicone keycap 3, and the other end of the key connector 5 is connected to a fixing plate 6, a groove 4 is opened inside the waterproof silicone keycap 3, a card slot 7 is opened on one side of the fixing plate 6, the card slot 7 is a truncated cone structure, the length of the key connector 5 is greater than the depth of the groove 4 and the card slot 7, one end of the key connector 5 is located inside the groove 4, and the key is pressed. The other end of the key connector 5 is located inside the card slot 7, a sliding pad 9 is provided on the other side of the fixed plate 6, and a limiting plate 11 is provided on the other side of the sliding pad 9. A first protrusion 8 is fixedly connected to one side of the fixed plate 6, and a through hole 10 is provided inside the sliding pad 9. The first protrusion 8 passes through the through hole 10, a second protrusion 12 is fixedly connected to one side of the limiting plate 11, and a sliding key 13 is fixedly connected to the other side of the limiting plate 11. A fixed cover plate 14 is installed on the outside of the outer shell 1, a through opening 15 is provided inside the fixed cover plate 14, and a limiting groove 16 is provided on the inner side of the fixed cover plate 14.

[0034] The principle of controlling the opening and closing of the law enforcement recorder is as follows: in the initial state, the law enforcement recorder is in the closed state, and the sliding key 13 is in the closed position. When the law enforcement recorder needs to be opened, the sliding key 13 is first pushed horizontally so that the sliding key 13 drives the limit plate 11 fixedly connected thereto to perform horizontal linear motion synchronously. During this process, the second protrusion 12 fixedly connected to one side of the limit plate 11 will perform horizontal linear motion on one side of the first protrusion 8. When the center line of the cylindrical structure of the second protrusion 12 and the center line of the frustum-shaped structure of the first protrusion 8 approach each other and gradually overlap, the second protrusion 12 will generate a thrust on the first protrusion 8, causing the fixed plate 6 connected to the first protrusion 8 to move toward the inside of the outer shell 1, and the direction of movement of the sliding key 13 is perpendicular to the direction of movement of the fixed plate 6. The fixed plate 6 moves toward the inside of the outer shell 1. During the process, the key connector 5 will be pushed, and then the key connector 5 will push the waterproof silicone keycap 3. After the waterproof silicone keycap 3 is squeezed, the law enforcement recorder will be turned on. Similarly, when the law enforcement recorder needs to be turned off, the sliding key 13 is first pushed horizontally in the opposite direction, so that the sliding key 13 drives the limit plate 11 fixedly connected to it to perform reverse horizontal linear motion. In this process, the center line of the cylindrical structure of the second protrusion 12 and the center line of the truncated cone structure of the first protrusion 8 are separated from each other until the inclined outer surface of the second protrusion 12 is parallel to the inclined outer surface of the first protrusion 8. The second protrusion 12 will not generate thrust on the first protrusion 8. At this time, the thrust exerted on the fixed plate 6 and the key connector 5 will disappear, and then the key connector 5 will drive the fixed plate 6 to move in the opposite direction for reset, and will not generate thrust on the waterproof silicone keycap 3. Then the law enforcement recorder will be turned off.

[0035] See also Figures 1-6 The first bump 8 is composed of a truncated cone block and a quadrilateral block, the second bump 12 is composed of a cylinder and a trapezoidal block, and the slope of the inclined outer surface of the second bump 12 is equal to the slope of the inclined outer surface of the first bump 8.

[0036] It is worth mentioning that: in the closed state, when the inclined outer surface of the second protrusion 12 is parallel to the inclined outer surface of the first protrusion 8, the second protrusion 12 will not generate thrust on the first protrusion 8. At this time, the distance between the limit plate 11 and the fixed plate 6 is the shortest. In the open state, the center line of the cylindrical structure of the second protrusion 12 will coincide with the center line of the frustum-shaped structure of the first protrusion 8. During the opening process, the second protrusion 12 connected to the limit plate 11 will generate thrust on the fixed plate 6 through the first protrusion 8, causing the fixed plate 6 to move toward the inside of the shell 1, thereby making the distance between the limit plate 11 and the fixed plate 6 reach the farthest.

[0037] See also Figures 1-6The limiting plate 11 is located inside the limiting groove 16, the sliding key 13 passes through the through opening 15, and the two sides of the limiting plate 11 have an uneven structure. The connection between the limiting plate 11 and the limiting groove 16 is a sliding connection, and the length of the limiting plate 11 is less than the length of the limiting groove 16.

[0038] It should be noted that the limit plate 11 is made of elastic plastic material. Since the limit plate 11 fits tightly with the limit groove 16, sufficient thrust is required when pushing the sliding key 13 connected to the limit plate 11 to prevent the limit plate 11 from sliding randomly, which is helpful to prevent misoperation of the switch structure.

[0039] See also Figures 1-6 , the length of the sliding pad 9 is greater than the length of the limiting plate 11, and the length of the through hole 10 is greater than the length of the first protrusion 8;

[0040] It is worth mentioning that the sliding pad 9 is arranged between the fixed plate 6 and the limit plate 11, and the sliding pad 9 is tightly fitted with the fixed cover plate 14. The sliding pad 9 can prevent moisture from entering the interior of the housing 1, thereby improving the waterproof performance of the switch structure.

[0041] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
