Description

Technical Field

[0001] The present invention relates to the technical field of automobile autonomous driving testing, and in particular to an auxiliary device for an autonomous driving robot. Background Art

[0002] For various tests before a car leaves the factory, such as durability, safety and other performance tests, there are many uncertain factors in the test process. If the driver controls the vehicle for testing, the driver's own safety is difficult to be guaranteed. In addition, during a long period of time and repeated testing, the driver's driving state and body reaction will directly affect the vehicle test results. Therefore, an autonomous driving robot is needed to replace the driver to complete the driving test task of the car. The autonomous driving robot can accurately and reliably control the car, and can maintain high accuracy and repeatability, thereby ensuring the accuracy and reliability of the vehicle test data.

[0003] Announcement No. CN116352734B provides an auxiliary structure for an autonomous driving robot, which belongs to the technical field of automobile autonomous driving test, and includes a fixed circular plate, a basic circular plate rotatably connected to the fixed circular plate, a wheel rim fixing part, a straight line correction part and an auxiliary fixing part. A dual fixing method is adopted in which the wheel rim fixing part and the auxiliary fixing part cooperate, and the dual fixing is implemented by means of the steering wheel rim and the spokes. The wheel rim fixing part and the auxiliary fixing part work independently. When the connection between the wheel rim fixing part and the steering wheel rim is loose and relative sliding occurs, resulting in the steering wheel not being fixed by the wheel rim fixing part or the control degree is reduced, the auxiliary fixing part is the existence of a backup fixing source, ensuring that the autonomous driving robot can still control the steering wheel. When the wheel rim fixing part is firmly connected to the steering wheel rim, the existence of the auxiliary fixing part can further improve the precise control of the steering wheel by the autonomous driving robot.

[0004] However, during the working process of the above-mentioned product, the wheel rim fixing part is composed of three independent design structures. Secondly, the autonomous driving robot can test drive cars of different models and steering wheels of different sizes. In this way, the wheel rim fixing part needs to be adjusted one by one when installing it with the steering wheel. This is not only troublesome but also wastes a lot of installation time. Therefore, it is not convenient to perform adaptive installation and positioning of steering wheels of different sizes, and the convenience of installation is still relatively poor.

[0005] Therefore, it is necessary to provide an auxiliary device for an autonomous driving robot to solve the above technical problems. Summary of the invention

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] The present invention provides an auxiliary device for an automatic driving robot.

[0021] In the first embodiment, please combine Figures 1 to 9, an auxiliary device for an autonomous driving robot, comprising a fixing plate 1 and a steering wheel 3; The outer wall of the fixing plate 1 is rotatably connected with a mounting tube 2, and four positioning mechanisms 4 are equidistantly installed on the outer wall of the mounting tube 2 and located at the axis of the mounting tube 2, and an inner plate 5 is fixedly installed on the inner wall of the mounting tube 2, and a two-way electric cylinder 10 is installed inside the mounting tube 2 and located on the right side of the inner plate 5 through bolts, and a push rod 11 is installed inside the two-way electric cylinder 10, and four clamping mechanisms 7 are installed inside the mounting tube 2 and located at the left end of the push rod 11, and a bracket 6 is fixedly installed on the inner wall of the mounting tube 2; The positioning mechanism 4 comprises a positioning frame 41 fixedly mounted on the outer wall of the mounting tube 2, a sleeve 42 fixedly mounted inside the positioning frame 41, a key rod 43 slidably connected inside the sleeve 42, a positioning block 44 fixedly mounted at the bottom end of the key rod 43, a return spring 45 sleeved inside the sleeve 42 and on the outer wall of the key rod 43, and a guide wheel 46 fixedly mounted at the top end of the key rod 43; See also Figure 3 and Figure 4 : First, the installation tube 2 and the steering wheel 3 need to be installed. Before installation, the user needs to fit the four positioning blocks 44 and the outer wall of the steering wheel 3. After the fitting is completed, the user needs to press the installation tube 2 hard. When the pressure is applied, the positioning block 44 will slide and rise inside the sleeve 42 along the inclined control key rod 43 in contact with the steering wheel 3, and the return spring 45 can be compressed during the sliding process; See also Figure 5 and Figure 6 : Finally, the steering wheel 3 can completely enter the interior of the mounting tube 2. After the positioning block 44 and the steering wheel 3 are separated, the return spring 45 automatically returns to the initial state, and the right sides of the four positioning blocks 44 block the steering wheel 3, limiting the steering wheel 3 inside the mounting tube 2.

[0022] A mounting rod 12 is fixedly provided at the left end of the push rod 11, and the number of the mounting rods 12 is four. The clamping mechanism 7 includes a mounting seat 71 fixedly provided on the outer wall of the mounting rod 12, and a plurality of positioning springs 72 are installed inside the mounting seat 71. The outer ends of the plurality of positioning springs 72 are all fixedly provided with positioning pins 73.

[0023] See also Figure 7 and Fig. 9 : When the steering wheel 3 is completely limited inside the mounting tube 2, the user needs to clamp and lock the steering wheel 3, and the bidirectional electric cylinder 10 can be started to drive the push rod 11 to move horizontally to the left. During the pushing process, the four mounting rods 12 will be driven to push the clamping mechanism 7 close to the steering wheel 3; When contacting the outer wall of the steering wheel 3 , the contacted positioning pin 73 will slide and move inside the mounting seat 71 adaptively according to the shape of the steering wheel 3 , thereby adaptively changing the clamping degree according to the shape of the steering wheel 3 .

[0024] The bottom of the positioning block 44 is in a 45-degree inclined surface structure, and the bottom end of the return spring 45 is in contact with the outer wall of the key rod 43 .

[0025] The front ends of the plurality of positioning pins 73 are all arc-shaped, and the plurality of positioning pins 73 and the mounting seat 71 are slidably connected.

[0026] It is understandable that the positioning block 44 is designed with an inclined surface, so that the user can quickly fit the positioning mechanism 4 and the steering wheel 3 together, allowing the user to install more quickly.

[0027] Please refer again Figure 8 : The mounting rod 12 is mounted with the clamping mechanism 7 by means of bolts, so that the clamping mechanism 7 can be disassembled and installed.

[0028] This embodiment: Compared with the traditional design, this case is designed with four equidistantly distributed positioning blocks 44 on the outside of the mounting tube 2. Before locking the steering wheel 3, the user can quickly bring the inclined surfaces of the four positioning blocks 44 close to fit the outer wall of the steering wheel 3. When pressed, the four positioning blocks 44 shrink in conjunction to ensure that the steering wheel 3 can enter the interior of the mounting tube 2. This design can not only quickly calibrate and fit steering wheels 3 of different sizes (the diameter of the steering wheel 3 needs to be within the inclined surface range of the positioning blocks 44), but also quickly limit the corresponding steering wheel 3 inside the mounting tube 2. At the same time, the design of the clamping mechanism 7 can also adaptively change the degree of clamping according to the surface shape of the steering wheel 3, thereby ensuring that the clamping force area is maximized, and the stability of the clamping can be effectively guaranteed.

[0029] For the second embodiment, please refer to Figures 7 to 9 , further comprising a stabilizing mechanism 9; The stabilizing mechanism 9 includes a negative pressure machine 91, an inner tube 92 is installed in the middle position inside the mounting seat 71, a limit spring 93 is installed inside the inner tube 92, an adsorption tube 94 is fixedly provided at the outer end of the limit spring 93, a rubber ring 95 is fixedly provided at the front end of the adsorption tube 94, and a through hole 96 is opened on the outer wall of the adsorption tube 94.

[0030] See also Fig. 9: The adsorption tube 94 is located in the middle position of the mounting seat 71. When the clamping mechanism 7 is clamping the steering wheel 3, the adsorption tube 94 will also slide inside the inner tube 92, and the steering wheel 3 will resist the sliding compression of the control limit spring 93 inside the inner tube 92 during the clamping process. When the through hole 96 enters the position of the air outlet of the inner tube 92, the through hole 96 will be connected with the air outlet of the inner tube 92 to form a connection. If the steering wheel 3 is larger, the clamping degree of the clamping mechanism 7 will be deeper. If the steering wheel 3 is smaller, the clamping degree of the clamping mechanism 7 will be smaller. If the clamping degree is large, the staggered seam between the through hole 96 and the inner tube 92 hole will be large, and the adsorption force will be strong. If the clamping degree is small, the staggered seam between the through hole 96 and the inner tube 92 hole will be small, and the adsorption force will be small.

[0031] The outer wall of the adsorption tube 94 and the inner wall of the inner tube 92 are slidably connected, and the through hole 96 and the inner hole of the inner tube 92 are matched.

[0032] The inner tube 92 is sealed and installed by using a hose and a negative pressure machine 91 , and the negative pressure machine 91 is located at the left end of the push rod 11 .

[0033] It can be understood that the steering wheel 3 is in contact with the rubber ring 95, so that the sealing of the adsorption tube 94 during adsorption can be ensured; When the negative pressure machine 91 is started, air can be evacuated from the inner tube 92 through the hose to form a negative pressure environment, thereby ensuring that the adsorption tube 94 can perform secondary stabilization on the steering wheel 3 .

[0034] In this embodiment: a stabilizing mechanism 9 is provided inside the clamping mechanism 7, and when the clamping mechanism 7 is in the clamping process, the adsorption tube 94 will also move synchronously with the movement of the positioning pin 73, and the adsorption tube 94 can make the through hole 96 and the hole inside the inner tube 92 form an interlaced hole position when sliding, and can adaptively change the adsorption stabilizing force according to the size of the steering wheel 3. The larger the steering wheel 3 is, the greater the adsorption force is, and the smaller the steering wheel 3 is, the smaller the adsorption force is. Therefore, such a design not only enables the present device to have the function of secondary adsorption stabilization, but also can adaptively change the adsorption force according to the size of the steering wheel 3.

[0035] For the third embodiment, please refer to Fig.10 and Fig.11 A separation mechanism 8 is installed on the outside of the installation cylinder 2 and at the same horizontal position as the four positioning mechanisms 4. A connecting frame 14 is installed on the right end of the push rod 11. A mounting box 81 is fixedly provided on the outer wall of the installation cylinder 2. A through slot 13 is opened on the outer wall of the installation cylinder 2 and located on the right side of the installation box 81. A gear 82 is rotatably connected to the inside of the installation box 81. The upper and lower sides of the gear 82 are meshed with a first rack 83 and a second rack 84. A connecting rod 85 is fixedly provided on the side wall of the first rack 83, and a separation block 86 is fixedly provided on the outer end of the connecting rod 85.

[0036] See also Fig.10 : During the operation of the first embodiment, the user needs to start the two-way electric cylinder 10 to control the internal push rod 11 to move horizontally to the left. During the movement of the push rod 11 to the left, the clamping mechanism 7 will be driven to clamp the steering wheel 3. During the movement to the left, the right end of the push rod 11 will drive the connecting frame 14 to slide inside the slot 13. During the sliding process, the second rack 84 will be driven to pull the gear 82 to rotate and engage to control the first rack 83 so that the connecting rod 85 is away from the positioning mechanism 4. In this way, during the operation of the first embodiment, the separation mechanism 8 will not interfere with the positioning mechanism 4.

[0037] See also Fig.10 and Fig.11 : When the first embodiment is completed, when the user needs to release the clamped steering wheel 3, he needs to control the push rod 11 to move to the right. During the movement, the connecting frame 14 will be driven to pull the second rack 84 to engage the control gear 82 to engage the first rack 83 to control the connecting rod 85 to drive the separation block 86 to approach the guide wheel 46. At this time, the guide wheel 46 will rise along the inclined surface of the separation block 86. During the rising process, the key rod 43 will be driven to rise to control the four positioning blocks 44 to move in conjunction to rise to avoid the steering wheel 3. The user can directly separate and remove the mounting tube 2 and the steering wheel 3.

[0038] The connecting frame 14 and the slot 13 are slidably connected, the first rack 83 and the second rack 84 are both slidably connected to the inner wall of the installation box 81, and the outer wall of the separation block 86 and the guide wheel 46 are in contact with each other.

[0039] This embodiment: This case is designed with a separation mechanism 8. During the working process of the first embodiment, the user needs to operate the steering wheel 3 to switch from the clamping state to the loose state. During the switching process, the push rod 11 can be controlled to continue to move to the right. During the movement, the four separation blocks 86 can be linked and controlled to push the guide wheel 46 to rise along the inclined surface of the separation block 86, and can be linked to rise to avoid the steering wheel 3. Therefore, such a design can easily and easily separate and remove the steering wheel 3 and the mounting tube 2, so that it can facilitate the user's quick operation and also enhance the convenient operability of the device.

[0040] Please refer to Figures 1 to 11 The working principle of an auxiliary device for an autonomous driving robot provided by the present invention is as follows: Step S1: First, the steering wheel 3 needs to be limited inside the installation tube 2, and the four positioning blocks 44 are fitted with the outer wall of the steering wheel 3. After the fitting is completed, the user needs to press the installation tube 2 hard. When the positioning block 44 is pressed, it will slide and rise inside the sleeve 42 along the inclined control key rod 43 in contact with the steering wheel 3, and the return spring 45 can be compressed during the sliding process; See also Figure 5 and Figure 6 : Finally, the steering wheel 3 can completely enter the interior of the mounting tube 2. After the positioning block 44 and the steering wheel 3 are separated, the return spring 45 automatically returns to the initial state, and the right sides of the four positioning blocks 44 block the steering wheel 3, limiting the steering wheel 3 inside the mounting tube 2.

[0041] Step S2: Start the bidirectional electric cylinder 10 to drive the push rod 11 to move horizontally to the left, and in the process of pushing, the four mounting rods 12 will be driven to push the clamping mechanism 7 close to the steering wheel 3; When the outer wall of the steering wheel 3 is contacted, the contacted positioning pin 73 will slide and move inside the mounting seat 71 according to the shape of the steering wheel 3, so that the clamping degree can be changed according to the shape of the steering wheel 3. Then the user needs to install the autonomous driving robot on the fixed plate 1. After the installation is completed, the autonomous driving robot can control the installation cylinder 2 to operate and rotate the steering wheel 3 according to the preset parameters of the test.

[0042] Step S3: During the clamping process of the clamping mechanism 7, the adsorption tube 94 will also move synchronously with the movement of the positioning pin 73, and the adsorption tube 94 can make the through hole 96 and the hole inside the inner tube 92 form an interlaced hole position when sliding, and can adaptively change the adsorption stabilizing force according to the size of the steering wheel 3. The larger the steering wheel 3 is, the greater the adsorption force is, and the smaller the steering wheel 3 is, the smaller the adsorption force is. Therefore, such a design not only enables the device to have the function of secondary adsorption stabilization, but also can adaptively change the adsorption force according to the size of the steering wheel 3.

[0043] Step S4: When releasing the clamped steering wheel 3, it is necessary to control the push rod 11 to move to the right. During the movement, the connecting frame 14 will be driven to pull the second rack 84 to engage the control gear 82 to engage the first rack 83 to control the connecting rod 85 to drive the separation block 86 to approach the guide wheel 46. At this time, the guide wheel 46 will rise along the inclined surface of the separation block 86. During the rising process, the key rod 43 will be driven to rise to control the four positioning blocks 44 to move in conjunction to avoid the steering wheel 3. The user can directly separate and remove the mounting tube 2 and the steering wheel 3.
