Description

Technical Field

[0001] This application belongs to the field of accessories for small vehicles, and specifically relates to a camera bracket applied to small vehicles. Background Art

[0002] The applicant's prior application proposed a small vehicle chassis and a small vehicle. During the running of the small vehicle, visual information needs to be collected. The video acquisition module (camera) fixedly installed on the small vehicle is visually limited during the running process due to the height limitation of the functional small vehicle itself, which does not conform to the viewing angle observed during normal running, resulting in an increase in the control difficulty during remote control running. Therefore, a liftable camera bracket needs to be equipped for the small vehicle. In addition, when only a single camera is installed on some small vehicles, a rotation function needs to be added to increase the acquisition angle. Summary of the Invention

[0003] Technical Problem: The technical problem to be solved by this application is to provide a liftable and angle-rotatable camera dedicated to functional small vehicles, providing a hardware basis for the small vehicle to achieve real-time video acquisition and transmission.

[0004] Technical Solution: A camera bracket for a small vehicle includes a fixed seat, a lifting mechanism, and a rotating mechanism. The lifting mechanism includes a fixed rod and a lifting rod, and the rotating mechanism is arranged at the upper end of the lifting rod; the fixed seat is used to connect with a prepared seat body on the small vehicle chassis.

[0005] A double-track integrating limit and power taking is arranged inside the fixed rod. The double-track refers to two tracks, and the two vertical tracks are separately and independently arranged, playing a dual role of limiting and supplying power to the rotating mechanism at the top of the lifting rod. That is, a carbon brush is arranged on the convex part (slidingly connected with the track) of the supporting lifting rod. The fixed rod and the lifting rod are integrally made of insulating materials.

[0006] During implementation, those skilled in the art need to set at least two tracks to achieve the dual functions of limiting / power taking. On this basis, those skilled in the art can add additional tracks to increase the lifting stability, or can add a limit for the maximum stroke in the cooperation between the two.

[0007] The double-track is arranged on the inner wall of the fixed rod. When the small vehicle is in use, it inevitably needs to cope with various outdoor weather conditions. Placing the double-track on the inner wall of the fixed rod helps to play a certain waterproof role.

[0008] Furthermore, the lifting rod includes an inner wall embedded and connected with the double-track from inside the fixed rod and an outer wall slidably sleeved on the outer layer of the fixed rod. That is, the lifting rod is provided with an intermediate sandwich layer, and the rod wall of the fixed rod is placed inside the sandwich layer. At the lowest point of the stroke, the outer wall of the lifting rod completely wraps the fixed rod.

[0009] Further, the lifting mechanism includes a threaded rod disposed in the middle of the fixed rod, and a threaded hole is provided in the middle of the lifting rod and is connected to the threaded rod in a matching manner. By rotating the threaded rod forward / backward, the lifting rod where the threaded hole is located is driven to move upward or downward.

[0010] Further, the bottom of the threaded rod passes through the fixed seat and is connected to the lifting motor. The lifting motor is used to drive the rotation of the threaded rod.

[0011] Further, the position of the threaded hole is close to the bottom of the lifting rod. The distance between the threaded hole and the top of the lifting rod is the maximum stroke of the lifting. Therefore, setting the threaded hole close to the bottom of the lifting rod can maximize the lifting stroke.

[0012] Further, the rotating mechanism includes a mounting seat provided at the top of the lifting rod, and a mounting hole for supporting the rotating base is provided on the mounting seat. The mounting hole is a circular hole, and a bearing can be installed in the hole to be connected to the rotating base.

[0013] Further, the rotating base includes a connecting portion disposed in the mounting hole. The connecting portion is nested in the mounting hole and can axially slide in the mounting hole or be connected through a bearing;

[0014] It further includes a mounting table provided above the connecting portion and a transmission gear provided below the connecting portion. The mounting table is used to mount the camera, and the transmission gear is used to be meshed and connected to the driving wheel.

[0015] Further, the transmission gear is meshed with the driving wheel connected to the rotating motor.

[0016] Further, the transmission gear is an internal gear ring gear. Since the space at the top of the lifting rod is limited, using an internal gear ring can improve the overall compactness.

[0017] The beneficial effects of the present application are as follows: A double track integrating limit and power taking is provided inside the fixed rod. The double track refers to two tracks, which are separately and independently provided vertically, and play a dual role of limiting and supplying power to the rotating mechanism at the top end of the lifting rod.

[0018] The lifting rod is provided with an intermediate sandwich layer, and the rod wall of the fixed rod is placed inside the sandwich layer. At the lowest point of the stroke, the outer wall of the lifting rod completely wraps the fixed rod, and the waterproof effect is remarkable.

[0019] The transmission gear is an internal gear ring gear. Since the space at the top of the lifting rod is limited, using an internal gear ring can improve the overall compactness.

[0020] Through the settings of the lifting mechanism and the rotating mechanism, the height requirements and angle requirements for video acquisition required by the trolley are met. BRIEF DESCRIPTION OF THE DRAWINGS [[ID=!]] [[ID=!]]

Detailed implementation manners

[0029] As Figure 1 shown, for a camera bracket of a trolley, the bottom plate in the figure is the mounting plate 1 on the trolley chassis for mounting the camera bracket. The mounting plate 1 is provided with mounting holes 2 for connecting the fixing base 5, and a transmission hole 3 for arranging the lifting motor 14 is provided in the middle thereof. Fixing holes 4 for fixing the transmission motor are provided around the transmission hole 3.

[0030] Referring to Figure 2 , the fixing base 5 and the fixing rod 6 are integral. The fixing rod 6 is vertically arranged on the fixing base 5. The fixing base 5 is provided with a mating hole 7 that mates with the mounting hole 2. The fixing rod 6 is hollow, and two vertical tracks 8 are provided on the inner side wall of the fixing rod 6. The two tracks 8 are arranged opposite to each other. A conductive material covering layer for brush connection is provided in the track 8, and the covering layer is continuously arranged along the direction of the track 8 without interruption. The rod body of the fixing rod 6 and the fixing base 5 are made of insulating materials.

[0031] Referring to Figure 3, the lifting rod 9 includes an inner wall 10 embedded and connected to the double track 8 inside the fixed rod 6 and an outer wall 11 sleeved on the outer layer of the fixed rod 6 in a sliding manner. Among them, a continuous and uninterrupted brush is provided at the embedded connection part, which is in contact connection with the conductive material covering layer on the track 8. That is, the lifting rod 9 is provided with an intermediate sandwich layer, and the rod wall of the fixed rod 6 is placed inside the sandwich layer. At the lowest point of the stroke, the outer wall 11 of the lifting rod 9 completely wraps the fixed rod 6.

[0032] Refer to Figure 4 , a nut 12 is provided at the central position near the bottom of the lifting rod 9. The nut 12 is fixed to the inner wall 10 of the lifting rod 9, and the hole direction of the nut 12 is the same as the lifting direction of the lifting rod 9.

[0033] Refer to Figure 9 , it further includes an adjusting screw rod 13 threadedly engaged with the nut 12. The adjusting screw rod 13 passes through the transmission hole 3 and is connected to the lifting motor 14. That is, the rotation of the screw rod is driven by the rotation of the lifting motor 14, and then through the cooperation of the screw rod and the nut 12, the lifting of the lifting rod 9 is driven.
