Description

Technical Field

[0001] This invention relates to the field of law enforcement equipment technology, and in particular to a law enforcement recorder that is easy to recharge. Background Technology

[0002] A law enforcement recorder, also known as a police law enforcement recorder or on-site law enforcement recorder, integrates digital video recording, digital photography, and walkie-talkie functions. It can digitally record dynamic and static on-site situations during law enforcement, making it convenient for law enforcement use in various environments. Law enforcement recorders are often used in conjunction with walkie-talkies, and can be connected to walkie-talkies to provide them with a microphone and speaker.

[0003] Chinese patent application No. 201911054210.8 discloses a law enforcement recorder, which includes a housing, a support member, a button module, and a circuit board. The housing comprises a first shell and a second shell, which are fitted together to form a receiving cavity. The support member is housed within the receiving cavity and has a receiving cavity. The support member includes a bottom wall and multiple side walls, which are connected to the edge of the bottom wall and bent relative to the bottom wall to form the receiving cavity together. The button module is disposed on the side wall. The circuit board is stacked on the side of the bottom wall opposite to the receiving cavity and is connected to the button module. The side walls provide support to the button module, thereby improving the pressing force of the button module, enhancing its pressing effect, and extending its service life.

[0004] However, this technical solution has the following problems: the law enforcement recorder in this technical solution needs to be charged with a charging cable and charger. When the charging cable and charger are missing, the law enforcement recorder cannot be charged. Secondly, it is inconvenient to carry the charging cable and charger with you. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a law enforcement recorder that is easy to charge. By detachably housing the plug component on the recorder body, the plug component can be pulled out when needed, and the charging cable can be retracted and extended through the cable extension component. This eliminates the need for a separate charging cable and charger, making it convenient to charge the law enforcement recorder. Furthermore, it also solves the problem of the inconvenience of carrying a charging cable and charger.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A law enforcement recorder that is easy to charge includes: a law enforcement recorder body; a plug component, which is pluggably accommodated on the law enforcement recorder body; a cable delivery component, which is installed in the law enforcement recorder body for receiving and delivering a charging cable; the cable delivery component includes: a baffle; a cable delivery shaft, which is installed on the baffle for receiving and delivering the charging cable; a power component, which provides power to the cable delivery shaft; an auxiliary component, which orderly delivers the cable onto the cable delivery shaft; and a check valve component, which controls the rotation and stopping of the cable delivery shaft.

[0008] Preferably, the anti-reverse assembly includes: a connecting plate with a groove; a sliding member slidably disposed in the groove; and a rotating disk mounted on one end of the pay-off shaft with a groove b. The sliding end of the sliding member slides in the groove b to realize the rotation and anti-rotation of the pay-off shaft.

[0009] Furthermore, the slide rail b includes an outer track, an inner track, and a limiting track; the outer track includes a first end face a, a second end face a, and a transition end face a, with a discontinuity surface a between the first end face a and the second end face a; the inner track includes a first end face b, a second end face b, and a transition end face b, with a discontinuity surface b between the first end face b and the second end face b, and a filter surface c between the first end face b and the second end face a; the limiting track includes a slot surface, with a discontinuity surface c between the slot surface and the second end face a, and a discontinuity surface d between the slot surface and the first end face b; a magnet is installed on the rotating disk, and the magnetic attraction of the magnet prevents the sliding end of the sliding member from sliding from the second end face a into the filter surface c.

[0010] (5) In this invention, the charging port moves forward and the steel wire rope pulls the sliding plate away from the clearance hole, making it easier for the charging port to be inserted into the clearance hole. The charging port moves backward and, under the action of the elastic connector b, drives the sliding plate to be inserted into the clearance hole. The sliding plate plays a dustproof role. When the charging port is not in use, the clearance hole is sealed to prevent dust from entering the equipment and extend the service life of the equipment.

[0011] (6) The present invention can drive the rotating part to rotate by pushing the push block, which drives the fan-shaped rack to rotate and mesh with the gear c. The gear c drives the rotating core plate to rotate at a certain angle, so that the core can be adapted to the three-hole socket. In this way, it can be adapted and switched between the three-hole socket and the two-hole socket, which has good applicability.

[0012] In summary, the present invention has advantages such as not requiring additional charging cable and charger, preventing cable tangling, switching between three charging modes, and dust protection. Attached Figure Description

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0041] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0042] Example 1

[0043] like Figure 1 and Figure 2 As shown, the present invention provides a law enforcement recorder that is easy to charge, including: a law enforcement recorder body 1; a plug component 2, which is detachably accommodated on the law enforcement recorder body 1; and a cable delivery component 3, which is installed in the law enforcement recorder body 1 for retracting and extending the charging cable.

[0044] Preferred, such as Figure 3 As shown, the wire feeding component 3 includes: a baffle 31; a wire feeding shaft 32, which is mounted on the baffle 31 and is used to feed and retract the charging cable; a power component 33, which provides power to the wire feeding shaft 32, preferably driven by a spring; an auxiliary component 34, which enables the wire to be fed and retracted in an orderly manner on the wire feeding shaft 32; and a check component 35, which restricts the rotation and stop of the wire feeding shaft 32.

[0045] This invention allows the plug component 2 to be detachably housed on the body 1 of the law enforcement recorder. When needed, the plug component 2 can be pulled out, and the charging cable can be retracted and extended through the cable extension component 3. This eliminates the need for a separate charging cable and charger, making it convenient to charge the law enforcement recorder. Furthermore, it also solves the problem of the inconvenience of carrying a charging cable and charger with you.

[0046] It should be noted that the body 1 of the law enforcement recorder is provided with an isolation cavity 11. The isolation cavity 11 is used to accommodate the cable laying component 3 and the plug component 2. The isolation cavity 11 plays an isolation role to prevent the cable laying component 3 from affecting the use of other parts inside the body 1 of the law enforcement recorder.

[0047] Specifically, such as Figure 7 As shown, the anti-reverse assembly 35 includes: a connecting plate 351, with a groove 3511 inside the connecting plate 351; a sliding member 352, which is slidably disposed in the groove 3511; and a rotating disk 353, which is mounted on one end of the pay-off shaft 32, with a sliding groove b3531 inside the rotating disk 353; the sliding end of the sliding member 352 slides in the sliding groove b3531 to realize the rotation and anti-rotation of the pay-off shaft 32.

[0048] like Figure 8 As shown, the sliding member 352 includes: a sliding rod a3521, in which a sliding groove 35211 is formed; a pressing rod 3522, which is slidably disposed in the sliding groove 35211; the sliding rod a3521 and the pressing rod 3522 are connected by an elastic support member a3523.

[0049] Preferred, such as Figure 9 As shown, the slide rail b3531 includes an outer track 35311, an inner track 35312, and a limiting track 35313;

[0050] like Figure 10 As shown, the outer track 35311 includes a first end face a353111, a second end face a353112 and a transition end face a353113, wherein a discontinuity surface a353114 is provided between the first end face a353111 and the second end face a353112.

[0051] like Figure 11 As shown, the inner track 35312 includes a first end face b353121, a second end face b353122, and a transition end face b353123. A discontinuity surface b353124 is provided between the first end face b353121 and the second end face b353122. The first end face b353121 and the second end face b353112 are connected by a filter surface c353125.

[0052] like Figure 12 As shown, the limiting track 35313 includes a slot surface 353131, a discontinuity surface c353132 between the slot surface 353131 and the second end surface a353112, and a discontinuity surface d353133 between the slot surface 353131 and the first end surface b353121.

[0053] like Figure 11 As shown, a magnet 3532 is installed on the rotating disk 353. The magnetic attraction of the magnet 3532 prevents the sliding end of the sliding member 352 from sliding from the second end face a353112 into the filter surface c353125.

[0054] Cable laying process: Manually pull out the plug component 2 from the law enforcement recorder body 1, drive the cable laying shaft 32 to rotate to realize cable laying, drive the rotating disk 353 to rotate, and the sliding end of the sliding component 352 slides in the outer track 35311. Its specific sliding direction is from the first end face a353111 to the second end face a353112 to the transition end face a353113, and so on in a cycle. This process is always in the cable laying process.

[0055] Wire stopping process: Release the plug component 2, and drive the wire feeding shaft 32 to rotate in the opposite direction under the action of the power component 33. The sliding end of the slider 352 moves from the first end face a353111 to the transition end face a353113 to the second end face a353112. Due to the setting of the discontinuity surface a353114, the sliding end of the slider 352 cannot slide from the second end face a353112 to the first end face a353111. Under the guidance of the discontinuity surface a353114, the sliding end of the slider 352 slides into the slot surface 353131, the wire stops retracting, the length of the wire is constant, and charging can be achieved using the plug component 2.

[0056] The following two situations may occur after the stop-line process;

[0057] When the length of the wire is insufficient, continue to pull out the plug component 2. Under the action of the break surface c353132, the sliding end of the sliding component 352 slides from the slot surface 353131 to the first end surface b353121, and then enters the second end surface a353112 after passing through the filter surface c353125. The subsequent process is the same as the above wire feeding process and wire stopping process.

[0058] Retracting process: Gently pull out the plug component 2. Under the action of the break surface c353132, the sliding end of the slider 352 slides from the slot surface 353131 to the first end surface b353121. At this time, release the plug component 2. Under the action of the power component 33, drive the wire feeding shaft 32 to rotate in the opposite direction. The sliding end of the slider 352 slides from the first end surface b353121 to the transition end surface b353123 to the second end surface b353122, realizing the wire retraction. This cycle is repeated to realize the wire retraction function.

[0059] Preferred, such as Figure 3 and Figure 4As shown, the auxiliary component 34 includes: a rotating shaft 341, with a cross-spiral groove 3411 inside the rotating shaft 341, the cross-spiral groove 3411 being interconnected; a guide rod 342, the guide rod 342 being mounted on one side of the rotating shaft 341; a sliding block 343, the sliding block 343 being slidably mounted on the guide rod 342; a sliding rod b344, the sliding rod b344 being mounted on the sliding block 343 and sliding within the cross-spiral groove 3411; a guide ring 345, the guide ring 345 being mounted on the sliding block 343 and guiding the winding and unwinding of the wire; and a guide plate 346, the guide plate 346 being mounted on the sliding rod b344 and guiding the sliding rod b344 within the cross-spiral groove 3411. A reset component is provided between the guide plate 346 and the sliding rod b344, the reset component preferably being a spring, and the wire passes through the guide ring 345.

[0060] During the take-up process, the wire feeding shaft 32 is driven to rotate, and the rotating shaft 341 is driven to rotate via a belt. The sliding rod b344 slides in the cross spiral groove 3411, driving the sliding block 343 to slide back and forth on the guide rod 342. Then, the guide ring 345 makes the wire orderly take-up on the wire feeding shaft 32, preventing the wire from getting messy. In addition, orderly wire take-up saves space and reduces the size of the equipment.

[0061] Example 2

[0062] like Figure 13 As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is as follows:

[0063] Specifically, such as Figure 13 As shown, the plug component 2 of this embodiment includes: a core 21; a rotating member 22, which is mounted on the core 21 and has multiple sets of ribs 221, one end of which has a beveled opening 2211; and a fixing sleeve 23, which has multiple sets of beveled grooves 231 and multiple sets of guide grooves 232. The ribs 221 slide in the guide grooves 232. Preferably, there are four sets of ribs 221 and eight sets of beveled grooves 231. Preferably, there are four sets of guide grooves 232, and the beveled grooves 231 and guide grooves 232 are spaced apart.

[0064] The push sleeve 24 has multiple sets of V-shaped grooves 241, and the fixed sleeve 23 has a track groove 233. The slide rail 242 installed on the push sleeve 24 slides in the track groove 233. The push sleeve 24 has a push block 243 installed on it. The outer shell 25 is located outside the insert 21. The rotating part 22 is connected to the outer shell 25 by an elastic support b253. The multi-mode charging component 26 provides multiple charging methods. The V-shaped grooves 241 are preferably eight sets. The outer shell 25 has a clearance groove to avoid the push block 243.

[0065] In this invention, the first push of the push block 243 drives the push sleeve 24 to move, which in turn drives the rotating member 22 and the insert 21 to move. When the rib 221 leaves the guide groove 232, under the guidance of the chamfered opening 2211, the rib 221 is inserted into the V-shaped groove 241, driving the rotating member 22 to rotate a certain angle. At this time, the push block 243 is released, and under the action of the elastic support member b253, the rotating member 22 and the push sleeve 24 are driven to return. The rib 221 slides into the chamfered groove 231. At this time, the insert 21 extends out of the outer shell 25, and the charging function can be realized.

[0066] Pushing the push block 243 again drives the push sleeve 24 to move, which in turn drives the rotating part 22 and the insert 21 to move. When the rib 221 leaves the angled groove 231, it is guided by the chamfered opening 2211 to insert the rib 221 into the V-shaped groove 241, driving the rotating part 22 to rotate a certain angle. At this time, the push block 243 is released, and the rotating part 22 is driven to return under the action of the elastic support b253. The rib 221 slides into the guide groove 232. At this time, the insert 21 returns to its original position and retracts into the outer shell 25.

[0067] Simply put: pushing the pusher block 243 once will cause the insert 21 to extend, allowing it to be used for charging. Pushing the pusher block 243 again will cause the insert 21 to retract into the housing 25, keeping the outer surface of the law enforcement recorder flat and without protrusions, resulting in an attractive appearance.

[0068] Furthermore, such as Figure 16 As shown, the multi-mode charging component 26 includes: a rack plate a261, which is mounted on one of the ribs 221; gears a262, with two sets of gears a262 disposed on both sides of the rotating member 22; rack plates b263, with two sets of rack plates b263 disposed on both sides of the rotating member 22; the rack plates b263 mesh with the gears a262; and a charging port 264, which is mounted on the rack plate b263. The two charging ports 264 are configured differently, preferably Type-C and Micro USB.

[0069] A fixed plate 265 is disposed inside the outer casing 25; an elastic connector a266 is disposed between the fixed plate 265 and the rack plate b263; the outer casing 25 has an clearance hole 251 and a sliding groove a252; a sliding plate 267 is slidably disposed in the sliding groove a252; an elastic connector b268 is disposed in the sliding groove a252; and a wire rope 269 is connected at one end to the rack plate b263 and at the other end to the sliding plate 267.

[0070] Figure 17In its initial state, the ferrule 21 is located inside the housing 25, and the working process is as follows:

[0071] The first push of the push block 243 times causes the plug 21 to extend out of the outer shell 25, and the plug 21 is used to realize the charging function.

[0072] The second push of the pusher block 243 times causes the insert 21 to retract into the outer casing 25, and the state is as follows. Figure 18 As shown, after pushing the pusher block 243 twice, the rotating part 22 and the rack plate a261 are driven to rotate 90°. Under the action of the elastic support b253, the rack plate a261 is driven to move. Through the gear a262, the port of a charging port 264 moves forward and inserts into the clearance hole 251 so that it is flush with the end face of the outer shell 25. At this time, the charging port 264 can be used to realize the charging function.

[0073] The third push of the push block 243 times causes the insert 21 to extend out of the outer shell 25. The insert 21 is used to realize the charging function. At the same time, it drives the rack plate a261 to move. Through the gear a262, it drives the port of a charging port 264 to move backward and leave the clearance hole 251.

[0074] The fourth push of the push block 243 times causes the insert 21 to retract into the outer shell 25, while simultaneously driving the rotating component 22 and the rack plate a261 to rotate 180° relative to their original state.

[0075] The fifth push of the pusher block 243 times causes the insert 21 to extend out of the outer casing 25, and the charging function is achieved using the insert 21.

[0076] The sixth push of the pusher block 243 times causes the insert 21 to retract into the outer casing 25, and the state is as follows. Figure 19 As shown, after pushing the pusher block 243 6 times, relative to the original state, the drive rotating part 22 and the rack plate a261 rotate 270°. Under the action of the elastic support part b253, the drive rack plate a261 moves, and through the gear a262, it drives the port of another charging port 264 to move forward and insert into the clearance hole 251 so that it is flush with the end face of the outer shell 25. At this time, the charging function can be realized by using the other charging port 264.

[0077] The seventh push of the push block 243 times causes the insert 21 to extend out of the outer shell 25. The insert 21 is used to realize the charging function. At the same time, it drives the rack plate a261 to move. Through the gear a262, it drives the port of another charging port 264 to move backward and leave the clearance hole 251.

[0078] The eighth push of the pusher block 243 times causes the insert 21 to retract into the outer shell 25, while simultaneously driving the rotating component 22 and the rack plate a261 to rotate 360° relative to their original state, returning them to their original state.

[0079] In summary, by pushing the pusher block 243 eight times in one cycle, three charging modes can be switched, which is highly flexible and widely applicable.

[0080] It should be noted that: such as Figure 20 When the charging port 264 moves forward, the steel wire rope 269 pulls the sliding plate 267 away from the clearance hole 251, making it easier for the charging port 264 to insert into the clearance hole 251. When the charging port 264 moves backward, the elastic connector b268 drives the sliding plate 267 to insert into the clearance hole 251. The sliding plate 267 serves as a dustproof device, preventing dust from entering the equipment. When the charging port 264 is not in use, the clearance hole 251 is sealed to extend the service life of the equipment.

[0081] Example 3

[0082] like Figure 13 As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is as follows:

[0083] The insert 21 in this embodiment includes: a square core plate 211; a rotating core plate 212, which is rotatably disposed at both ends of the square core plate 211; and an angle adjustment part 213, which adjusts the angle of the rotating core plate 212 to adapt to a three-hole socket.

[0084] The angle adjustment unit 213 includes: a sector rack 2131, with two sets of sector racks 2131 symmetrically arranged on the rotating member 22; a connecting rod 2132, which is mounted on the rotating core plate 212; a gear b 2133, which is mounted on the connecting rod 2132; and a gear c 2134, with two sets of gears c 2134 symmetrically arranged on the square core plate 211.

[0085] Gear d2135, rotatably mounted on the square core plate 211, meshes with one of the gears c2134; gear d2135 is connected to one of the gears b2133 via a transmission unit 2136, and the other gear b2133 is connected to the other gear c2134 via a transmission unit 2136; reset unit 2137 is mounted on the connecting rod 2132; reset unit 2137 includes: reset plate 21371, which is mounted on the connecting rod 2132; elastic support c21372, with two sets of elastic support c21372 located at both ends of the reset plate 21371. The function of reset unit 2137 is to maintain the angle of the rotating core plate 212 without external force. Reset unit 2137 can also use a reset spring.

[0086] As can be seen from Embodiment 2, pushing the pusher block 243 can drive the rotating part 22 to rotate, causing the fan-shaped rack 2131 to rotate and mesh with the gear c2134. Driving the gear c2134 to rotate causes the rotating core plate 212 to rotate at a certain angle. At this time, the insert 21 can be adapted to a three-hole socket.

[0087] Specifically, in the original state, such as Figure 24 As shown, the sector rack 2131 is not engaged with the gear c2134. Under the action of the reset unit 2137, the rotating core plate 212 does not rotate. At this time, a two-hole socket can be used to push the push block 243, which drives the sector rack 2131 to rotate and engage with the gear c2134. The gear c2134 rotates, causing the rotating core plate 212 to rotate at a certain angle. At this time, the insert 21 can be adapted to a three-hole socket. Push the push block 243 again to drive the sector rack 2131 to rotate and disengage from the gear c2134. Under the action of the reset unit 2137, the rotating core plate 212 returns to its original state and can be adapted to a two-hole socket.

[0088] It should be noted that: the front end of the outer casing 25 is provided with a disc that matches the rotating core plate 212. The rotating core plate 212 is inserted into the disc, and the disc can rotate in coordination with the rotating core plate 212.

[0094] Step 5: Push the pusher block 243 times for the fifth time, and the plug 21 will extend out of the outer shell 25. Use the plug 21 to realize the charging function.

[0095] Step six: Push the pusher block 243 times for the sixth time, and the insert 21 retracts into the outer casing 25, as shown in the figure. Figure 19 As shown, after pushing the pusher block 243 6 times, relative to the original state, the drive rotating part 22 and the rack plate a261 rotate 270°. Under the action of the elastic support part b253, the drive rack plate a261 moves, and through the gear a262, it drives the port of another charging port 264 to move forward and insert into the clearance hole 251 so that it is flush with the end face of the outer shell 25. At this time, the charging function can be realized by using the other charging port 264.

[0096] Step 7: Push the push block 243 times for the seventh time. The insert 21 extends out of the outer shell 25. The insert 21 is used to realize the charging function. At the same time, it drives the rack plate a261 to move. Through the gear a262, it drives the port of another charging port 264 to move backward and leave the clearance hole 251.
