[0036] Next, in combination with the specific embodiments of the present utility model, the technical solutions in the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope protected by the present utility model.

[0037] As Figure 1-6 shown, the elevator audio and video recorder of the present utility model includes a housing 1, a battery assembly 2, a circuit assembly 3, a camera 4, a recording and playback audio module 5, and a fixed clip 6.

[0038] Among them, the housing 1 is used to carry other components. The housing 1 includes a housing frame 11, two cover plates 12, and a partition 13. Openings 101 are provided at both ends of the housing frame 11, that is, the housing frame 11 is a rectangular tubular structure. The two cover plates 12 are both fixedly arranged on the housing frame 11 and respectively block the two openings 101; the partition 13 is fixedly arranged inside the housing frame 11.

[0039] The battery assembly 2 is used to supply power to this recorder, and it is a prior art.

[0040] The circuit assembly 3 is used to realize the transmission of electric energy and signals, so as to cooperate with the battery assembly 2 to ensure the normal operation of this recorder. It is a prior art. The battery assembly 2 and the circuit assembly 3 are respectively fixedly arranged on both sides of the partition 13 and are located between the two cover plates 12. As Figure 1 shown, the partition 13 isolates the battery assembly 2 and the circuit assembly 3 in two areas inside the housing 1. It has a heat insulation effect, reduces the influence of the heat generated during the operation of the battery assembly 2 on the circuit assembly 3, thereby protecting the circuit assembly 3 and ensuring the normal use of the recorder.

[0041] The partition 13 is preferably made of aluminum material, and corresponding heat dissipation fins and heat dissipation holes are provided on the housing 1 to accelerate the heat dissipation efficiency of the battery assembly 2 and improve the heat dissipation effect of the recorder.

[0042] The frame 11 includes an outer frame 111, a limiting ring 112, sliding ribs 113 and reinforcing ribs 114. As Figure 1 and Figure 2 shown, the limiting ring 112 is fixedly arranged inside the outer frame 111, and the partition plate 13 is detachably fixed to one side of the limiting ring 112. It can not only cooperate with the two cover plates 12 to facilitate the disassembly and assembly operations of each component inside the recorder, but also limit the partition plate 13 to install the partition plate 13 in a proper position.

[0043] As Figure 2 shown, a chute 102 is formed on the partition plate 13. The sliding ribs 113 are fixedly arranged inside the outer frame 111 and slidably arranged inside the chute 102. Preferably, the partition plate 13 and the limiting ring 112 are fixedly connected by threads. After removing the bolts between the two, the sliding cooperation between the chute 102 and the sliding ribs 113 can be used to limit the partition plate 13. Specifically, preferably, the inner diameter of the chute 102 gradually increases from the end close to the center point of the partition plate 13 to the end far from the center point of the partition plate 13, so as to facilitate the sliding rib 113 to slide into the chute 102. Preferably, the cross section of the chute 102 is an isosceles trapezoid.

[0044] As Figure 3 shown, the reinforcing ribs 114 are fixedly arranged inside the outer frame 111 and abut against the cover plate 12 on the side of the circuit component 3 away from the partition plate 13, so as to prevent the cover plate 12 from being damaged by extrusion after being pressed and improve the anti-pressure performance of the circuit component 3.

[0045] As Figure 3 shown, the sliding ribs 113 and the reinforcing ribs 114 are respectively located on both sides of the partition plate 13, that is, the partition plate 13 slides into the outer frame 111 from the opening 101 on the side away from the circuit component 3, abuts against and is fixed to the limiting ring 112. By cooperating with the reinforcing ribs 114 and the cover plate 12, a good protection space can be provided for the circuit component 3.

[0046] The cover plate 12 includes a plate body 121, a convex ring 122 and a plurality of buckles 123. Among them, the two plate bodies 121 respectively abut against both ends of the outer frame 111 and seal the two openings 101 respectively; the convex ring 122 is fixedly arranged on the plate body 121 and abuts against the inside of the outer frame 111, thereby improving the sealing performance between the cover plate 12 and the frame 11.

[0047] As Figure 4 and Figure 5 shown, the frame 11 further includes a plurality of tongues 115, and the tongues 115 are fixedly arranged inside the outer frame 111; the buckles 123 are fixedly arranged on the convex ring 122 and are clamped with the tongues 115, so as to connect the frame 11 and the cover plate 12 by a clamping method, thereby improving the connection convenience between the two.

[0048] The camera 4 is used to record videos of the elevator components, which is a prior art.

[0049] The recording and playing module 5 is used to record sounds of the elevator components. Both the camera 4 and the recording and playing module 5 are arranged in the housing frame 11 and are respectively used to record videos and sounds of the elevator components. Specifically, both the camera 4 and the recording and playing module 5 can be fixedly connected to the partition plate 13 and are respectively arranged on both sides of the partition plate 13.

[0050] The fixing clip 6 is used to fix this recorder. As Figure 1 shown, a camera hole 103 is formed in one of the cover plates 12, and the camera 4 passes through the camera hole 103 to record videos of the elevator through the camera hole 103. The fixing clip 6 is fixedly arranged on the other cover plate 12, so that the fixing clip 6 can be clipped on the operator's clothes to record videos of the elevator.

[0051] Under different working conditions, this recorder needs to be installed at different positions. For example, use a bracket to place the recorder in front of the elevator-related components, or use a suspension rope to hang this recorder in front of the elevator-related components. To increase the installation forms of this recorder, threaded holes 104 and hanging rope holes 105 are formed in the housing frame 11. The threaded holes 104 and the hanging rope holes 105 are oppositely arranged on two opposite side surfaces of the housing frame 11 and are respectively used to connect with the screw of the support base and the hanging rope, improving the adaptability of this recorder.

[0052] The working principle of the elevator audio and video recorder of the present utility model is as follows:

[0053] As Figure 1 shown, the partition plate 13 separates the battery assembly 2 and the circuit assembly 3 into two areas inside the machine shell 1, thus playing a heat insulation effect and reducing the influence of the heat generated by the battery assembly 2 on the circuit assembly 3. Moreover, the partition plate 13 can also cooperate with the heat dissipation holes or heat dissipation fins on the machine shell 1 to improve the heat dissipation efficiency.

[0054] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
