Description

TECHNICAL FIELD

[0001] The utility model relates to laser radar technical field especially relates to a laser radar lens protection device. BACKGROUND

[0002] Lens is the most important and most precise component of laser radar, and needs to be used with special care. Especially in the field, it is more necessary to protect the laser lens comprehensively to prevent dust or sand from falling into the lens and damaging the lens. In the prior art, a dust cover is generally arranged outside the lens or a wiper is used to protect the lens. With the development of science and technology, the miniaturization trend of laser radar is more and more obvious. In view of this, the existing laser radar lens protection device using a wiper or a dust cover arranged on the lens needs to occupy a relatively large space, which is not conducive to the miniaturization development of laser radar. SUMMARY

[0003] The utility model wants to overcome the prior art's insufficient, provide a compact structure, small, be favorable to laser radar miniaturization's laser radar lens protection device.

[0004] The utility model employs the technical scheme, a laser radar lens protection device, in the overall structure of laser radar, be located upper portion and be provided with upper cover, be provided with scanning hole matched with the lens of laser radar on the upper cover, the laser radar lens protection device is protected to the lens of radar in the scanning hole place cooperation, the laser radar lens protection device includes the protection plate sliding rail that sets up in the upper cover inside two sides symmetry, the lens protection plate is slidably fitted on the protection plate sliding rail, the lens protection plate is adapted to the scanning hole, first spring fixed shaft is arranged below the protection plate sliding rail on both sides respectively, two second spring fixed shafts are arranged on the lower side of the lens protection plate, the first spring fixed shaft is connected with the second spring fixed shaft and has return spring.

[0005] Therefore, by the setting of the lens protection device, when the radar needs to be used, it can be pushed away from the scanning hole, and in the non-working state of the radar, the lens protection plate is pulled back to block the scanning hole, so that foreign matters are prevented from entering the upper cover and affecting the lens. Especially in the field, foreign matters are easy to enter the upper cover and contaminate the optical dustproof lens. It is also conducive to the miniaturization development of laser radar.

[0006] A manual knob is arranged on the upper side of the lens protection plate and exposed on the scanning hole. Therefore, by the manual knob, the lens protection plate can be conveniently opened or closed, and the convenience of use is improved.

[0007] The first spring fixing shaft is positioned on the sliding rail of the protective plate near one side of the scanning hole. This side is the side of the lens protective plate that is close to the position of the lens protective plate when the scanning hole is not blocked. The second spring fixing shaft is located in the middle of the lower side of the lens protective plate.

[0008] Therefore, when the manual push block is manually pushed, when the lens protective plate is pushed to the set position of the first spring fixing shaft, as the reset spring switches between the stretched and compressed states, the lens protective plate is pushed to cover the scanning hole or pulled away from the scanning hole. This ensures that the lens protective plate only switches between two states: covering the scanning hole and moving away from the scanning hole, thus guaranteeing the stability of the lens protective plate.

[0010] Fig. 2 This is a simplified structural diagram of the present invention from a second perspective;

[0011] Fig. 3 This is a simplified structural diagram of the present invention from a third-person perspective. Detailed Implementation

[0012] like Figs. 1-3 As shown, a laser radar lens protection device includes a top cover 1 in the overall structure of the laser radar. The top cover 1 has a scanning hole 2 that matches the laser radar lens. The laser radar lens protection device works in conjunction with the scanning hole 2 to protect the radar lens. The laser radar lens protection device includes protective plate sliding rails 3 symmetrically arranged on both sides inside the top cover 1. A lens protection plate 4 is slidably fitted on the protective plate sliding rails 3, and the lens protection plate 4 is adapted to the scanning hole 2. A first spring fixing shaft 5 is respectively arranged below the protective plate sliding rails 3 on both sides. Two second spring fixing shafts 6 are arranged on the lower side of the lens protection plate 4. A return spring 7 connects the first spring fixing shaft 5 and the second spring fixing shaft 6. A manual toggle block 8 is arranged on the upper side of the lens protection plate 4, and the manual toggle block 8 protrudes from the scanning hole 2.

[0013] The first spring fixing shaft 5 is positioned on the sliding rail 3 of the protective plate close to one side of the scanning hole 2. This side is the side of the lens protective plate 4 that is close to the position of the lens protective plate 4 when the scanning hole 2 is not blocked. The second spring fixing shaft 6 is located in the middle of the lower side of the lens protective plate 4.

[0014] Finally, it needs to be emphasized that the above is only the preferred embodiment of the present application, and is not intended to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
