[0031] In order to solve the problem that the camera of the bank patrol robot is prone to rapid shaking and large vibration in the prior art, the present application provides a patrol robot.
[0032] As shown in Figures 1 to 3 The present application provides a kind of patrol robot, including trolley main body 10, damping assembly 20 and image acquisition device 30.Damping assembly 20 is arranged on trolley main body 10, damping assembly 20 includes damping telescopic piece 21, elastic piece 22 and bearing piece 23, bearing piece 23 is arranged on one end of damping telescopic piece 21, elastic piece 22 is connected with bearing piece 23, to be used for buffering bearing piece 23 in the movement process of bearing piece 23.Image acquisition device 30 is arranged on bearing piece 23, image acquisition device 30 is used to obtain image along the way in the running process of trolley main body 10.
[0033] Applying the technical solution of this embodiment, the shock absorption component 20 mounted on the main body 10 of the inspection robot includes a damping telescopic member 21, an elastic member 22, and a support member 23. The support member 23 is mounted on one end of the damping telescopic member 21, and the elastic member 22 is connected to the support member 23 to buffer the support member 23 during its movement. An image acquisition device 30 is mounted on the support member 23 and is used to acquire images along the route during the movement of the main body 10. Thus, if the main body 10 experiences bumps during its movement, the support member 23 and the image acquisition device 30 mounted on it will move vertically along with the main body 10. Under the action of the shock absorption component 20, when the support member 23 and the image acquisition device 30 move downwards, the damping telescopic member 21 and the elastic member 22 absorb the impact energy of the support member 23 and the image acquisition device 30, reducing their downward speed. When the support member 23 and the image acquisition device 30 move downwards to their maximum speed... After the position is limited, the elastic element 22 will drive the carrier 23 and the image acquisition device 30 to reset. At this time, the damping telescopic element 21 can absorb the elastic potential energy of the elastic element 22 to reduce the upward movement speed of the carrier 23 and the image acquisition device 30. As a result, the carrier 23 and the image acquisition device 30 will only vibrate slowly and with small amplitude (energy is consumed by the damping telescopic element 21) during the bumping process of the vehicle body 10. This solves the problem of rapid shaking and large vibration of the camera of the bank inspection robot in the prior art.
[0034] Specifically, the main body 10 of the car is capable of moving along a preset trajectory or can be remotely controlled. Its structure is relatively conventional and will not be described in detail here.
[0035] like Figure 2 As shown, the shock absorption assembly 20 also includes a mounting member 24 disposed on the trolley body 10, and the damping telescopic member 21 includes a telescopic body 211 and a mounting portion 212. Mounting portions 212 are provided at both ends of the telescopic body 211. The mounting portion 212 at one end of the telescopic body 211 is used to connect with the mounting member 24, and the mounting portion 212 at the other end of the telescopic body 211 is used to connect with the bearing member 23. Thus, the mounting member 24 and the mounting portion 212 provide a basis for the connection between the telescopic body 211 and the trolley body 10, ensuring that the damping telescopic member 21 can be installed on the trolley body 10.
[0036] In this embodiment, the telescopic body 211 is a damped telescopic rod.
[0037] Specifically, the connection between the mounting part 212, the carrier 23 and the mounting part 24 can be welding or fastener connection.

In this way, the above setting actually makes the elastic member 22 sleeved on the telescopic main body 211 and connected with the mounting portions 212 located at two ends of the telescopic main body 211, which on one hand ensures that the buffering function of the elastic member 22 can be realized, and on the other hand guides the buffering direction of the elastic member 22 through the telescopic main body 211 to avoid the elastic member 22 from deviating, thereby improving the buffering reliability of the elastic member 22. Optionally, the elastic member 22 is a spring.
[0039] As shown in Figure 2 , the mounting member 24 includes a bottom plate 241 and a surrounding plate 242 arranged on the bottom plate 241. The mounting recess 243 is formed around between the bottom plate 241 and the surrounding plate 242, the damping telescopic member 21 is arranged on the bottom plate 241, and at least part of the damping telescopic member 21 is located in the mounting recess 243. In this way, the mounting member 24 can not only provide a mounting basis, but also protect the damping telescopic member 21 to prolong the service life of the damping telescopic member 21.
[0040] In the embodiment, the bottom plate 241 and the surrounding plate 242 are both rectangular, and the mounting recess 243 is a cuboid structure.
[0041] In the embodiment, the damping telescopic member 21 is provided with five, the elastic member 22 is provided with five, and the five damping telescopic members 21 and the five elastic members 22 are arranged one by one, wherein four are arranged near the top corners of the bottom plate 241, and the other is arranged at the geometric center of the bottom plate 241, so as to ensure that the bearing member 23 is uniformly stressed in the process of absorbing vibration energy, thereby preventing the bearing member 23 from tilting and shaking.
[0042] As shown in Figure 3 , the image acquisition device 30 includes a driving structure 31 and an image acquisition member 32. The driving structure 31 is arranged on the bearing member 23. The driving structure 31 is drivingly connected with the image acquisition member 32 to drive the image acquisition member 32 to rotate. In this way, the driving structure 31 can drive the image acquisition member 32 to rotate to take pictures of the bank from multiple angles to increase the shooting range of the image acquisition member 32.
[0043] In the embodiment, the image acquisition member 32 is a camera.
[0044] As shown in Figure 3As shown, the driving structure 31 comprises a mounting shell 311, a driving member 312 and a mounting plate 313.

The mounting plate 313 is arranged on the driving end of the driving member 312, and the mounting plate 313 is used for mounting the image acquisition member 32. In this way, the above arrangement can protect the driving member 312 by the mounting shell 311, so as to prolong the service life of the driving member 312, and the mounting plate 313 provides a mounting basis for the image acquisition member 32.
[0045] In the embodiment, the driving member 312 is a servo motor.
[0046] As shown in the figure, Figure 3 The mounting shell 311 also has heat dissipation holes 3111 communicating with the mounting cavity, and the heat dissipation holes 3111 are arranged on the side surface of the mounting shell 311. A plurality of heat dissipation holes 3111 are arranged in the height direction and / or the width direction of the mounting shell 311. In this way, the heat generated by the operation of the driving member 312 can be dissipated through the heat dissipation holes 3111, so as to avoid the accumulation of heat inside the mounting cavity, which causes the driving member 312 to heat up and shorten the service life. At the same time, the number of heat dissipation holes 3111 can ensure that the total area of the heat dissipation holes 3111 is large enough, while reducing the size of each heat dissipation hole 3111 to reduce the probability of external impurities entering the mounting shell 311 through the heat dissipation holes 3111.
[0047] As shown in the figure, Figure 1 The inspection robot also comprises an anti-collision assembly 40, and the anti-collision assembly 40 comprises an anti-collision member 41. The anti-collision member 41 is connected with the trolley body 10 through a connecting rod 42, and the anti-collision member 41 is located on one side of the trolley body 10. The anti-collision member 41 is arc-shaped and arranged around the trolley body 10. In this way, the above arrangement can prevent the trolley body 10 from directly colliding with external objects and causing damage to the trolley body 10, thereby prolonging the service life of the trolley body 10 and improving the safety of the trolley body 10 during inspection.
[0048] In the embodiment, the anti-collision member 41 is an arc-shaped anti-collision plate, and the connecting rod 42 is installed on the front and rear sides of the trolley body 10 by screws. The anti-collision members 41 on the front and rear sides are interchangeable.
[0049] Optionally, an elastic structure can be arranged on the anti-collision member 41 to further ensure that the trolley body 10 will not be damaged when a collision occurs.
[0050] Optionally, the elastic structure is made of rubber or silicone.
[0051] As shown in the figure, Figure 1As shown, the patrol robot further comprises an emergency alarm assembly 50 arranged on the trolley body 10 and comprising an alarm member 51 and a switch structure 52. The alarm member 51 is used to send an alarm signal, and the alarm signal comprises at least one of a light signal and a sound signal. The switch structure 52 is connected with the alarm member 51, and the switch structure 52 is used to control the alarm member 51 to be turned on or turned off. In this way, when an emergency occurs in the bank, the staff can press the switch structure 52 fixedly arranged on the top of the trolley body 10 to make the alarm member 51 quickly send an alarm, and the alarm signal comprises at least one of a light signal and a sound signal, so that the patrol robot has strong warning capability.
[0052] As shown in the drawings, Figure 1 The patrol robot further comprises a signal enhancer 60 and / or a temperature detection device 70. The signal enhancer 60 is arranged on the trolley body 10 and connected with the wireless transmission module of the trolley body 10, and / or the temperature detection device 70 is arranged on the trolley body 10 and used to detect the temperature in the running space. In this way, the signal enhancer 60 can enhance the signal transmission of the wireless transmission module in the patrol robot, thereby increasing the controllable radius of the patrol robot, and the temperature detection device 70 can monitor the temperature in the bank in real time.
[0053] Specifically, the temperature detection device 70 arranged on the trolley body 10 can move with the trolley body 10 to detect the temperature at each position in the bank. If the temperature at a position increases, it may mean that a fire has occurred at the position, that is, the patrol robot in the embodiment can also function as a fire detection device.
[0054] In the embodiment, the signal enhancer 60 and the temperature detection device 70 are arranged on the trolley body 10 at the same time.
[0055] Specifically, the trolley body 10 is provided with a wireless transmission module. During the operation of the patrol robot, the images captured by the image acquisition device 30 and the temperature information detected by the temperature detection device 70 are transmitted to the corresponding terminal device through the wireless transmission module, so that the staff can view the corresponding information. Therefore, the signal enhancer 60 is arranged on the trolley body 10 in the embodiment to improve the transmission signal strength and ensure the transmission stability of the corresponding information.
