Description

Technical Field

[0001] The utility model relates to the technical field of pest control robots, in particular to a braking mechanism of a pest control robot. Background Art

[0002] Disinfection and epidemic prevention robots are referred to as disinfection robots. The robot is a carrier, and a disinfection system is installed inside the robot. There are atomization disinfection robots, ultraviolet disinfection robots, plasma disinfection robots, strong light pulse disinfection robots, etc.

[0003] The known patent application number is: CN202220091521.2, which discloses a braking mechanism of a disinfection robot to solve the problem that the existing disinfection robot is unstable in parking and prone to overturning, including: a brake chuck, which is installed on the rotating shaft of the disinfection robot; a limit block, which is located on the side of the brake chuck, and a limit channel is provided in the middle of the limit block, and a V-shaped groove is provided at one end close to the brake chuck, and the limit channel is connected to the V-shaped groove; a telescope, which is installed on the side of the limit block away from the brake chuck, and the telescopic rod of the telescope is inserted into the limit channel; wherein, a connecting arm is hinged at the end of the telescopic rod of the telescope, and a roller is installed on the connecting arm; a plurality of arc-shaped notches are provided on the circumference of the brake chuck; when the telescopic rod is extended, the roller can be clamped between the arc-shaped notch and the side wall of the V-shaped groove. The braking mechanism can achieve short-distance rapid braking, stable parking on a slope, and is not prone to brake failure and overturning.

[0004] However, in the implementation of relevant technologies, it was found that the above-mentioned scheme has the following problems: when in use, it is not convenient to perform multiple shock-absorbing effects on the chassis. When the disinfection robot encounters a bumpy road, a bumpy force will be generated. In order to reduce the impact of the bumpy force on the internal parts of the robot and to meet the movement of the robot in different planes, most of them currently use a single spring structure to absorb the bumpy force. However, the shock-absorbing effect of relying solely on a single spring structure is poor, and the shock-absorbing effect of the spring will decrease with long-term use, thereby reducing the shock-absorbing effect and movement stability of the chassis.

[0027] Reference Figure 1-4 As shown, the brake mechanism of a disinfection robot provided by the utility model solves the problem of inconvenience in performing multiple shock-absorbing effects on the chassis raised in the above-mentioned background technology.

[0028] To achieve the above purpose, a braking mechanism of a disinfection robot includes a chassis 1 and a mounting plate 2 arranged above the chassis 1, a disinfection mechanism is arranged on the top of the mounting plate 2, and a control box 3 is fixedly installed on one side of the top of the mounting plate 2, wherein a main controller is installed in the control box 3 to facilitate the control of the electrical components in the device;

[0029] Two connecting bent rods 4 are symmetrically fixedly installed at the bottom of the mounting plate 2, and two sliders 5 are symmetrically slidably connected to the surface of the connecting bent rod 4. A shock absorbing spring 6 is sleeved on the surface of the connecting bent rod 4, and the two ends of the shock absorbing spring 6 are respectively connected to the two sliders 5;

[0030] The bottom of the slider 5 is hinged with a connecting rod 7 hinged with the chassis 1, and a V-shaped spring piece 8 connected with the chassis 1 is fixedly installed on one side of the connecting rod 7;

[0031] Two dampers 9 connected to the mounting plate 2 are symmetrically fixedly mounted on the top of the chassis 1. A second damping spring 10 is sleeved on the surface of the damper 9. The two ends of the second damping spring 10 are respectively connected to the chassis 1 and the mounting plate 2.

[0032] A moving mechanism is provided at the bottom of the chassis 1, a braking mechanism is provided on the moving mechanism, and anti-collision mechanisms are provided at both ends of the chassis 1.

[0033] The utility model provides a braking mechanism of a disinfection robot. When in use, the mobile mechanism can drive the chassis 1 to move and adjust, and the disinfection mechanism can disinfect the surrounding environment at the same time. When the movement stops, the mobile mechanism can be braked by the braking mechanism to prevent the chassis 1 from continuing to move due to inertia. During the movement, the anti-collision mechanism can reduce the collision force on the chassis 1 to avoid damage to parts in the device. When encountering uneven roads and bumps, the mounting plate 2 is forced to move downward to drive the connecting rod 7 to rotate, and the connecting rod 7 drives the slider 5 to slide relatively along the surface of the connecting bent rod 4 to squeeze the shock-absorbing spring 6. The spring 1 6 applies a reaction force to the slider 5, thereby achieving the effect of preliminary shock absorption on the chassis 1. At the same time, when the connecting rod 7 rotates, it can synchronously squeeze the V-shaped spring piece 8, so that it deforms after being stressed and exerts elastic force, thereby achieving the purpose of secondary shock absorption. In the process of the rear mounting plate 2 being forced to move downward, the damper 9 and the shock absorbing spring 2 10 are synchronously squeezed, so that the shock absorbing spring 2 10 is deformed and exerts a reaction force, and cooperates with the damper 9 to achieve the effect of shock absorption again, thereby achieving the effect of triple shock absorption of the bumpy force exerted on the chassis 1, without relying solely on the shock absorption performance of the spring, thereby extending the service life of the spring, and effectively improving the shock absorption effect and movement stability of the chassis 1.

[0035] Specifically, during disinfection, the disinfectant in the disinfectant tank 11 is pumped out by the pump body 12, and the disinfectant is transported to the spray pipe 13 through a pipeline for spraying, thereby achieving a spray disinfection effect.

The coupling is fixedly connected to the output end of the reduction motor 15 . The reduction motor 15 is electrically connected to the control box 3 .

[0038] Specifically, when moving, the reduction motor 15 drives the driving wheel 16 to rotate forward and backward to achieve the purpose of moving. When turning, the direction of the steering wheel 17 is adjusted by the steering assembly, and the different speeds of the two reduction motors 15 are used to achieve differential speed to drive the two driving wheels 16 to rotate, thereby achieving the effect of the robot moving and turning.

[0039] Furthermore, the braking mechanism includes a brake disc 18 fixedly mounted on the coupling surface, a connecting plate 19 symmetrically fixedly mounted on both sides of the rear end of the chassis 1, a telescopic member arranged on the top of the connecting plate 19, and a brake pad 25 fixedly connected to the output end of the telescopic member and matched with the brake disc 18.

[0041] Specifically, when the reduction motor 15 drives the driving wheel 16 to stop rotating, the telescopic cylinder 20 drives the brake pad 25 to move downward, so that the brake pad 25 contacts and rubs with the brake disc 18, so as to achieve the effect of braking the driving wheel 16, preventing the robot from continuing to move due to inertia after stopping, and effectively improving the braking and stopping effect of the robot.

[0042] Furthermore, the anti-collision mechanism includes two groups of L-shaped blocks 21 symmetrically fixedly installed at the front and rear ends of the chassis 1, a limiting rod 22 slidingly connected to one side of the L-shaped block 21, a protective plate 23 fixedly connected to one end of the limiting rod 22, and a buffer spring 24 sleeved on the surface of the limiting rod 22, and the two ends of the buffer spring 24 are respectively connected to the L-shaped block 21 and the protective plate 23.

[0043] Specifically, during the movement of the robot, the protective plate 23 collides with an object and is subjected to force, which drives the limit rod 22 to slide and squeeze the buffer spring 24, so that the buffer spring 24 applies a reaction force to the protective plate 23, thereby achieving the purpose of collision buffering of the protective plate 23, so as to reduce the collision impact on the chassis 1 and ensure the stability of the parts on the device.

[0045] Specifically, by providing an injection pipe, it is convenient to inject disinfectant into the disinfectant tank 11 to ensure the disinfection effect, and by providing a discharge pipe, it is convenient to discharge the remaining disinfectant in the disinfectant tank 11.

[0046] Working principle: When encountering bumps on uneven roads, the mounting plate 2 is forced to move downward to drive the connecting rod 7 to rotate, and the connecting rod 7 drives the slider 5 to slide relatively along the surface of the connecting bent rod 4 to squeeze the shock-absorbing spring 1 6, and the shock-absorbing spring 1 6 applies a reaction force to the slider 5, so as to achieve the effect of initial shock absorption on the chassis 1. At the same time, when the connecting rod 7 rotates, it can synchronously squeeze the V-shaped spring 8, so that it deforms after being stressed and applies elastic force, so as to achieve the purpose of secondary shock absorption. In the process of the rear mounting plate 2 being forced to move downward, the damper 9 and the shock-absorbing spring 10 are synchronously squeezed, so that the shock-absorbing spring 10 is deformed under stress and applies a reaction force, and cooperates with the damper 9 to achieve the effect of shock absorption again, thereby realizing the effect of triple shock absorption on the bumpy force applied to the chassis 1.
