Description

Technical Field

[0001] The present invention relates to the technical field of law enforcement recorders, and in particular to a low-power law enforcement recorder. Background Art

[0002] The law enforcement recorder has the features of small size, easy to carry, long standby time, etc. It is waterproof, shockproof and drop-resistant. The built-in infrared light can ensure clear images under night conditions, making it convenient for law enforcement use.

[0003] The recorder is usually worn on the chest for use. The recorder will be turned on in advance before law enforcement. The recorder exposed to the outside needs to ensure waterproofness, so most of the cover is sealed. The recorder in continuous work will continue to generate high temperature, which will cause discomfort when worn on the chest. When it is turned on when worn on the chest, it is not easy to detect whether it is turned on in time. And the recorder worn on the chest is often not turned off in time after use, resulting in continuous energy consumption of the recorder. Furthermore, in the process of law enforcement, the poor shock absorption effect of the recorder worn directly will affect the shooting effect. Based on this, a low-power law enforcement recorder is proposed. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that it is difficult to detect whether the existing recorder worn on the chest is turned on in time, and the recorder worn on the chest is often not turned off in time after use, resulting in continuous energy consumption of the recorder, and a low-power law enforcement recorder is proposed.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A low-power law enforcement recorder, comprising a combined switching shell and a recorder body arranged in the combined switching shell, wherein the combined switching shell is composed of an outer cover body and a telescopic cover body combined with the outer cover body, the back of the telescopic cover body is connected with a built-in adsorption plate through a magnetic attraction piece, and the recorder body is connected to the combined switching shell through a magnetic repulsion spring damping module;

[0007] An electric control template is arranged on the back of the recorder body, and a control switch for opening and closing the electric control template is arranged on the side wall of the telescopic cover;

[0008] The telescopic cover body is composed of a control template and a telescopic template. A rectangular notch adapted to the telescopic template is provided on the outer cover body. The telescopic cover body is located in the rectangular notch and is connected to each other through a columnar member.

[0009] The columnar member comprises an outer column cover arranged on the outer cover body and an inner column arranged on the outer side wall of the telescopic template. The inner column is located in the outer column cover and is connected to the inner wall of the outer cover body through a reset connection spring.

[0010] Preferably, the magnetic repulsion spring shock absorbing module comprises elastic slide bars fixedly arranged on both sides of the recorder body, the inner side wall of the telescopic template is provided with a slide rail bar for the elastic slide bar to move, and rubber shock absorbing blocks are arranged at both ends of the elastic slide bar.

[0011] Preferably, the magnetic attraction component includes a magnetic seat fixedly arranged at the four corners of the built-in adsorption plate, the magnetic seat is connected to a magnetic block via a built-in spring, and fixed magnetic disks magnetically attracted to the magnetic seat are arranged at the four corners of the control template.

[0012] Preferably, a central disk is rotatably arranged on the electric control template, the central disk is composed of two semicircular disks with opposite magnetic properties, a flexible film is arranged at the center of the built-in adsorption plate, and a magnetic repelling half disk used in conjunction with the central disk is arranged inside the flexible film.

[0013] Preferably, the control switch comprises a control sliding key arranged on the control template, a rack is arranged inside the control sliding key, and a gear ring meshing with the rack is fixedly arranged on the outer side wall of the central magnetic disk.

[0014] Preferably, an arc-shaped power-carrying cavity is provided inside the electric control template, the arc-shaped power-carrying cavity is connected to the central disk through a control shaft, and the central disk is connected to the arc-shaped power-carrying cavity through an arc-shaped conducting column.

[0015] Preferably, the telescopic template is densely provided with through holes for heat dissipation of the recorder body.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present invention protects the recorder body inside by providing a combined switching shell, and uses the magnetic seat and the recorder on the built-in adsorption plate to achieve adsorption, thereby ensuring that the recorder is firmly worn on the chest through the combined switching shell when not in use, and ensuring good sealing.

[0018] 2. The present invention adopts a unique design of the magnetic repulsion disk and the central magnetic disk. When the recorder is turned on, the magnetic attraction of the magnetic repulsion disk and the central magnetic disk is changed into a magnetic repulsion, thereby expanding the outer cover and the telescopic cover in the original storage state, thereby ensuring the heat dissipation effect when the recorder is in use.

[0019] 3. The present invention arranges the magnetic repulsion disk in the flexible film so that the magnetic repulsion disk in the flexible film generates inward pressure. The pressure is directly applied to the chest, which is obviously different from the recorder body in the unopened state, so that the user can clearly draw the difference, thereby reminding the user to close the law enforcement recorder in time when not in use.

[0020] 4. The present invention uses the effect of magnetic repulsion to enable the outer cover body and the telescopic cover body to unfold, and realizes shock absorption of the combined switching shell through the action of the reset connecting spring arranged in the columnar part on the telescopic template. The recorder in the combined switching shell is further shock-absorbed by the slide rail bar arranged on the recorder, ensuring the shooting effect of the law enforcement recorder even under intense movements during law enforcement, thereby meeting the shock absorption requirements of the law enforcement recorder.

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0027] Example, see Figure 1-4 A low-power law enforcement recorder includes a combined switching shell and a recorder body 1 arranged in the combined switching shell, the combined switching shell is composed of an outer cover body 2 and a telescopic cover body combined with the outer cover body 2, the telescopic cover body is composed of a control template 3 and a telescopic template 4, the outer cover body 2 is provided with a rectangular notch adapted to the telescopic template 4, the telescopic cover body is in the rectangular notch, and is connected to each other through a columnar member;

[0028] The telescopic template 4 is densely provided with hidden through holes 21 for heat dissipation of the recorder body 1 .

[0029] Among them, by setting the hidden through hole 21 on the telescopic template 4, when the recorder body 1 is opened for use, the telescopic template 4 will be extended outward, so that the hidden through hole 21 originally in the outer cover 2 is exposed, so as to achieve the effect of heat dissipation of the recorder body 1 therein, wherein the recorder body 1 is densely provided with heat dissipation ports;

[0030] It can ensure that the hidden through hole 21 is closed when not in use, thereby ensuring the sealing effect when not in use.

[0031] The columnar member includes an outer column cover 7 arranged on the outer cover body 2 and an inner column 8 arranged on the outer side wall of the telescopic template 4. The inner column 8 is located inside the outer column cover 7 and is connected to the inner wall of the outer cover body 2 through a reset connection spring.

[0032] The inner column 8 is located inside the outer column cover 7, and the reset connection spring realizes the connection between the two. When in use, the reset connection spring is in a stretched state, so that in the process of canceling the magnetic repulsion force, the reset connection spring can achieve the effect of driving the outer cover 2 and the telescopic cover to reset.

[0033] The back of the telescopic cover is connected to a built-in adsorption plate 5 through a magnetic attraction component. Furthermore, the magnetic attraction component includes a magnetic seat 12 fixedly arranged at the four corners of the built-in adsorption plate 5. The magnetic seat 12 is connected to a magnetic block 13 through a built-in spring. Fixed magnetic disks 14 magnetically attracted to the magnetic seat 12 are arranged at the four corners of the control template 3.

[0034] It should be noted that when the law enforcement recorder is worn, the built-in adsorption plate 5 is placed inside the clothes, and the recorder body 1 is placed outside the clothes. The law enforcement recorder is firmly worn on the clothes through the fixed magnetic disks 14 at the four corners of the built-in adsorption plate 5;

[0035] The magnetic suction seat 12 and the fixed magnetic disk 14 are magnetically attracted to each other, so that the clamping effect of the law enforcement recorder can be guaranteed at all times.

[0036] The recorder body 1 is connected to the combined switching shell through a magnetic repulsion spring shock absorbing module; further, the magnetic repulsion spring shock absorbing module includes an elastic slide bar 9 fixedly arranged on both sides of the recorder body 1, and the inner wall of the telescopic template 4 is provided with a slide rail bar 10 for the elastic slide bar 9 to move, and rubber shock absorbing blocks 11 are arranged at both ends of the elastic slide bar 9.

[0037] It is worth noting that the rubber damping block 11 is set. When the recorder body moves outward due to the magnetic repulsion force, thereby increasing the shooting distance, the elastic slide bar 9 originally in the slide bar 10 will be separated from the slide bar 10, and the rubber damping block 11 behind the slide bar 10 is in the slide bar 10 to ensure guidance during resetting. The rubber damping block 11 in front of the slide bar 10 is in contact with the inner wall of the outer cover 2, so that the shock absorption effect can be achieved by the rubber damping blocks 11 set at both ends of the elastic slide bar 9;

[0038] An electric control template 6 is arranged on the back of the recorder body 1, and a control switch for controlling the opening and closing of the electric control template 6 is arranged on the side wall of the telescopic cover;

[0039] Furthermore, a central magnetic disk 15 is rotatably provided on the electric control template 6 , and the central magnetic disk 15 is composed of two semicircular disks with opposite magnetic properties. A flexible film is provided at the center of the built-in adsorption plate 5 , and a magnetic repulsion disk 16 used in conjunction with the central magnetic disk 15 is provided inside the flexible film.

[0040] It is worth noting that the magnetic repulsion disk body 16 is also composed of two semicircular disk bodies with opposite magnetic properties. When the recorder body 1 is not in use, the magnetic repulsion disk body 16 and the central magnetic disk 15 are in an adsorption state. When the recorder body 1 is in use, the central magnetic disk 15 will rotate an angle, so that the two magnetic repulsion disk bodies 16 that were originally magnetically attracted are converted into a magnetically repelling state. At this time, a magnetic repulsion force is generated between the central magnetic disk 15 and the magnetic repulsion disk body 16, which satisfies the shock absorption and reminder functions when the recorder body 1 is turned on.

[0041] The setting of the flexible membrane is that when the recorder body 1 is opened, the magnetic repulsion disk 16 inside the flexible membrane will generate thrust, so that the magnetic repulsion disk 16 inside the flexible membrane generates inward pressure. The pressure is directly applied to the chest, which is obviously different from the recorder body 1 in the unopened state, so that the user can clearly draw the difference, thereby reminding the user to close the law enforcement recorder in time when not in use.

[0042] Furthermore, the control switch includes a control slide key 17 arranged on the control template 3, a rack is arranged inside the control slide key 17, and a gear ring 18 meshing with the rack is fixedly arranged on the outer side wall of the central magnetic disk 15.

[0043] A limit slide groove is provided on the control template 3, and the control slide key 17 is located in the limit slide groove, which can achieve a horizontal sliding effect.

[0044] Furthermore, an arc-shaped power-carrying cavity 19 is provided inside the electric control template 6 , and the arc-shaped power-carrying cavity 19 is connected to the central disk 15 through a control shaft, and the central disk 15 is connected to the arc-shaped power-carrying cavity 19 through an arc-shaped conducting column 20 .

[0045] A conductive contact is arranged inside the arc-shaped power-on cavity 19. By setting the arc-shaped conductive column 20, during the opening process, the arc-shaped conductive column 20 is brought into contact with the conductive contact inside the arc-shaped power-on cavity 19, thereby realizing the effect of turning on the power of the recorder body 1.

[0046] When the recorder needs to be turned on and used, the gear ring 18 meshing with the rack on the control slide key 17 drives the center disk 15 to rotate by sliding the control slide key 17. When the center disk 15 rotates, the arc-shaped conductive column 20 is driven to move in the arc-shaped power-on cavity 19, thereby achieving the effect of turning on the recorder body 1;

[0047] At this time, due to the rotation of the central magnetic disk 15, the attraction between the central magnetic disk 15 and the magnetic repulsion disk body 16 will change to repulsion, and the repulsive force will push the control recorder body 1 outward, and the telescopic template 4 will move out of the outer cover 2, and the hidden through hole 21 set on the telescopic template 4 will be opened to achieve the effect of heat dissipation;

[0048] At this time, the recorder itself can achieve a shock-absorbing effect due to the setting of the slide rail 10 (the rubber shock-absorbing block 11 behind the slide rail 10 is inside the slide rail 10 to ensure guidance during resetting, and the rubber shock-absorbing block 11 in front of the slide rail 10 is in contact with the inner wall of the outer cover 2, so that the rubber shock-absorbing blocks 11 set at both ends of the elastic slide bar 9 can achieve a shock-absorbing effect);

[0049] The outer cover 2 and the telescopic cover are connected by a reset connection spring arranged in the columnar member on the telescopic template 4 to achieve a further shock absorption effect;

[0050] This ensures that the shooting effect of the law enforcement recorder can be guaranteed even under intense movements during law enforcement, and meets the shock absorption requirements of the law enforcement recorder.

[0051] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
