Description

Technical Field

[0001] This utility model belongs to the technical field of obstacle driving platform, and specifically relates to an obstacle driving platform for intelligent driving perception testing. Background Technology

[0002] With the rapid development of intelligent driving technology, the ability of vehicle perception systems (such as cameras, millimeter-wave radar, and lidar) to identify and respond to dynamic obstacles has become a core testing requirement. In testing functions such as vehicle side collision warning, blind spot monitoring, and door opening warning, it is necessary to simulate scenarios where obstacles such as pedestrians, bicycles, and vehicles approach rapidly from the side or move dynamically.

[0003] In the side-view function test of the intelligent driving perception system, the existing obstacle driving platform can only realize the high-speed ejection action of the dummy. If it is necessary to simulate the scenario of smooth obstacle movement, it is necessary to change to a suitable driving platform. This technical limitation results in the relatively limited application scenarios of a single obstacle driving platform. Utility Model Content

[0004] To address the issue of needing to replace the corresponding drive platform when performing high-speed catapult launches or smooth movements, this utility model proposes an obstacle drive platform for intelligent driving perception testing, thereby overcoming the aforementioned technical problems existing in related technologies.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is an obstacle driving platform for intelligent driving perception testing, including a driving frame, a moving component is arranged inside the driving frame, a dummy is fixedly installed on the top of the moving component, an ejection component is arranged inside the driving frame, a driving component is arranged inside the driving frame, a plug-in component is arranged at the driving end of the driving component, and a guide component is arranged inside the driving frame corresponding to the plug-in component. The ejection assembly is used to eject and push the moving assembly so that the moving assembly can eject the dummy. The drive assembly is used to drive the plug-in assembly to move. At the same time, the plug-in assembly is connected to the moving assembly under the guidance of the guide assembly so that the drive assembly can drive the dummy to move smoothly through the moving assembly.

[0006] Furthermore, the moving component includes a moving groove, which is formed on the inner wall of the drive frame. A moving strip is movably connected inside the moving groove. A moving block is fixedly connected to one side of the moving strip. A mounting plate is fixedly connected to the top of the moving block. Rollers are provided at the bottom of the mounting plate and on the outer side of the moving block.

[0007] Furthermore, the ejection assembly includes a mounting frame, which is fixedly mounted on the outside of the drive frame. An ejection cylinder is fixedly mounted on one side of the mounting frame. The output end of the ejection cylinder passes through the mounting frame and is fixedly connected to an ejection plate. A buffer rubber pad is fixedly connected to one side of the inner wall of the drive frame.

[0008] Furthermore, the driving assembly includes a driving screw, which is rotatably connected inside the driving frame. A driving block is threadedly connected to the outer surface of the driving screw. A first guide rod is fixedly connected to the inner wall of the driving frame. The driving block is movably connected to the first guide rod. A driving motor is fixedly installed on the outer side of the driving frame. The output end of the driving motor is fixedly connected to the driving screw.

[0009] Furthermore, the plug-in assembly includes a through groove, which is formed on the top of the drive block and extends through the drive block. The inner wall of the through groove is provided with a storage groove, and a fixing rod is fixedly connected to the inner wall of the storage groove. A plug-in block is movably connected to the outer surface of the fixing rod, and a spring is provided on the outer side of the fixing rod. A plug-in groove is formed at the bottom of the moving block corresponding to the plug-in block.

[0010] Furthermore, the guiding assembly includes a guide plate, which is fixedly installed on the bottom of the inner wall of the drive frame. A guide groove is provided on one side of the guide plate, which consists of two horizontal grooves and one inclined groove. A socket groove is provided at the bottom of the plug-in block, and a guide rod is fixedly connected to the inner wall of the socket groove. The guide rod is movably connected to the guide groove.

[0011] Furthermore, an installation groove is provided on one side of the catapult plate, and an electromagnetic plate is fixedly installed inside the installation groove.

[0012] This utility model has the following beneficial effects: This invention uses a catapult assembly to launch a dummy using a moving assembly. By driving the plug-in assembly to move, the moving plug-in assembly connects to the moving assembly under the guidance of the guide assembly. This allows the driving assembly to slowly move the dummy via the plug-in assembly and the moving assembly. This configuration enables the obstacle driving platform to simultaneously have both catapult and slow-movement testing modes, thereby improving the overall practicality of the obstacle driving platform.

[0013] This invention uses a drive motor and a drive screw to move the drive block. When the drive block moves to the predetermined position, as the drive block continues to move, the guide rod pushes the plug-in block upward through the guide groove, allowing the plug-in block to move into the plug-in groove. At this time, the drive block can normally drive the moving block to move. The above configuration allows the plug-in block to automatically move into the plug-in groove simply by driving the drive block, making it more convenient to switch the movement mode of the dummy.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0018] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0019] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0020] Please see Figures 1-7 As shown, this utility model is an obstacle driving platform for intelligent driving perception testing, including a driving frame 1, a moving component 2 is arranged inside the driving frame 1, a dummy 3 is fixedly installed on the top of the moving component 2, an ejection component 4 is arranged inside the driving frame 1, a driving component 5 is arranged inside the driving frame 1, a plug-in component 6 is arranged at the driving end of the driving component 5, and a guide component 7 is arranged inside the driving frame 1 corresponding to the plug-in component 6. The ejection assembly 4 is used to eject and push the moving assembly 2 so that the moving assembly 2 can eject the dummy 3. The driving assembly 5 is used to drive the plugging assembly 6 to move. At the same time, the plugging assembly 6 is connected to the moving assembly 2 under the guidance of the guiding assembly 7 so that the driving assembly 5 can drive the dummy 3 to move smoothly through the moving assembly 2.

[0021] An infrared sensor is installed on the front side of the drive frame 1. When the car passes the infrared sensor, the infrared sensor transmits a signal to the controller, which then controls the ejection assembly 4 or the drive assembly 5 inside the drive frame 1. When the ejection assembly 4 is driven, the ejection end of the ejection assembly 4 pushes the moving assembly 2, so that the moving assembly 2, guided by the drive frame 1, moves the dummy 3. When the drive assembly 5 is driven, the drive end of the drive assembly 5 moves. At this time, the plug-in assembly 6 installed on the drive end is connected to the moving assembly 2 under the guidance of the guide assembly 7, so that the drive assembly 5 moves the dummy slowly through the plug-in assembly 6 and the moving assembly 2.

[0022] The ejection component 4 allows the moving component 2 to launch the dummy 3. The drive component 5 drives the plug-in component 6 to move. The moving plug-in component 6 is connected to the moving component 2 under the guidance of the guide component 7. Thus, the drive component 5 drives the dummy 3 to move slowly through the plug-in component 6 and the moving component 2. The above configuration allows the obstacle driving platform to have both ejection and slow movement test modes at the same time, thereby improving the overall practicality of the obstacle driving platform.

[0023] In one embodiment, the moving component 2 includes a moving groove 201, which is formed on the inner wall of the drive frame 1. A moving strip 202 is movably connected inside the moving groove 201. A moving block 203 is fixedly connected to one side of the moving strip 202. A mounting plate 204 is fixedly connected to the top of the moving block 203. Rollers 205 are provided at the bottom of the mounting plate 204 and on the outer side of the moving block 203.

[0024] A groove is provided on the ground corresponding to the drive frame 1. The drive frame 1 can be placed inside the groove, so that the roller 205 at the bottom of the mounting plate 204 contacts the ground. The dummy is installed on the top of the mounting plate 204 by fixing bolts. By pushing the moving block 203, the moving block 203 drives the moving strip 202 to move inside the moving groove 201. At the same time, the dummy moves on the top of the drive frame 1 under the action of the moving block 203. The setting of the moving groove 201 and the moving strip 202 allows the moving block 203 to move within the moving groove 201. When moving, the moving block 203 will not move out of the inside of the moving slot 201 at will, thus ensuring the stability of the moving block 203 when moving the dummy 3. When the moving block 203 moves, the rotating roller 205 at the bottom of the mounting plate 204 can roll on the ground, and the rotating roller 205 on the moving block 203 can roll on the inner wall of the drive frame 1. This setting makes the friction between the moving block 203 and the drive frame 1 smaller, so that the subsequent ejection assembly 4 can better eject the dummy 3 through the moving block 203.

[0025] In one embodiment, the ejection assembly 4 includes a mounting bracket 401, which is fixedly mounted on the outside of the drive frame 1. An ejection cylinder 402 is fixedly mounted on one side of the mounting bracket 401. The output end of the ejection cylinder 402 passes through the mounting bracket 401 and is fixedly connected to an ejection plate 403. A buffer rubber pad 404 is fixedly connected to one side of the inner wall of the drive frame 1.

[0026] By driving the ejection cylinder 402, the ejection plate 403 can generate a large pushing force on the moving block 203 under the push of the ejection end of the ejection cylinder 402. Under the action of the large pushing force, the moving block 203 can be ejected inside the drive frame 1. The buffer rubber pad 404 can buffer the ejected moving block 203, thereby avoiding damage to the moving block 203 and the drive frame 1 under large impact force.

[0027] In one embodiment, the drive assembly 5 includes a drive screw 501 rotatably connected inside the drive frame 1, a drive block 502 threadedly connected to the outer surface of the drive screw 501, a first guide rod 503 fixedly connected to the inner wall of the drive frame 1, the drive block 502 being movably connected to the first guide rod 503, and a drive motor 504 fixedly mounted on the outer side of the drive frame 1, the output end of the drive motor 504 being fixedly connected to the drive screw 501.

[0028] The drive screw 501 is driven by the drive motor 504, which in turn drives the drive block 502 to move inside the drive frame 1. When the drive block 502 moves to the predetermined position, the plug-in component 6 of the drive block 502 is connected to the moving block 203. At this time, the drive block 502 can drive the moving block 203 to move smoothly. The first guide rod 503 can guide the moving drive block 502, thereby ensuring the stability of the drive block 203 when it drives the moving block 203.

[0029] In one embodiment, the plug-in assembly 6 includes a through groove 601, which is formed at the top of the drive block 502 and extends through the drive block 502. The inner wall of the through groove 601 is provided with a receiving groove 602, and a fixing rod 603 is fixedly connected to the inner wall of the receiving groove 602. A plug-in block 604 is movably connected to the outer surface of the fixing rod 603, and a spring 605 is provided on the outer side of the fixing rod 603. The bottom of the moving block 203 is provided with a plug-in groove 606 corresponding to the plug-in block 604.

[0030] Spring 605 can pull the plug block 604 downward, causing the plug block 604 to move downward. At this time, the top of the plug block 604 is level with the top of the drive block 502. After the drive block 502 moves to the predetermined position, the plug block 604 moves upward under the guidance of the guide component 7, so that the plug block 604 can move into the plug groove 606. At this time, the drive block 502 is connected to the moving block 203 through the plug block 604 and the plug groove 606, so that the drive block 502 can normally drive the moving block 203 to move. This setting ensures that when the moving block 203 is launched by the ejector plate 403, the plug block 604 will not affect its movement.

[0031] In one embodiment, the guide assembly 7 includes a guide plate 701, which is fixedly installed on the bottom of the inner wall of the drive frame 1. A guide groove 702 is provided on one side of the guide plate 701. The guide groove 702 consists of two horizontal grooves and one inclined groove. A socket groove 703 is provided at the bottom of the plug-in block 604. A guide rod 704 is fixedly connected to the inner wall of the socket groove 703. The guide rod 704 is movably connected to the guide groove 702.

[0032] When the driving block 502 moves the insertion block 604, the socket groove 703 can move outside the guide plate 701. Simultaneously, the guide rod 704 inside the socket groove 703 moves within the lower horizontal groove. After the driving block 502 reaches the predetermined position, the guide rod 704 moves into the inclined groove and then directly into the upper horizontal groove. During this process, the guide rod 704, guided by the inclined groove, continuously drives the insertion block 604 upwards, causing it to move directly into the insertion groove 606. When the insertion block 604 completes its movement... After the dummy is fully moved into the insertion slot 606, the guide rod 704 also moves into the upper horizontal slot. The overall length of the insertion slot 606 is longer than that of the insertion block 604. This design allows the insertion slot 606 to have a certain clearance when the insertion block 604 moves into or out of the insertion slot 606, thus enabling the above-mentioned working process to proceed normally. At the same time, this design allows the insertion block 604 to automatically move into the insertion slot 606 simply by driving the drive block 502, making it more convenient to switch the movement mode of the dummy.

[0033] In one embodiment, for the above-mentioned catapult plate 403, a mounting groove 8 is provided on one side of the catapult plate 403, and an electromagnetic plate 9 is fixedly installed inside the mounting groove 8.

[0034] When the moving block 203 is about to move to the predetermined position under the push of the driving block 502, the insertion slot 606 and the insertion block 604, the electromagnetic plate 9 is charged and generates magnetic force to attract the moving block 203, so that the electromagnetic plate 9 can move to the predetermined position. At the same time, the moving block 203 will not move arbitrarily when it is in the predetermined position. Moreover, this setting will create a certain clearance space between the insertion slot 606 and the insertion block 604, so that the insertion block 604 can move out of the insertion slot 606 at an angle normally.

[0035] Through the above technical solution, 1. The ejection component 4 enables the moving component 2 to propel the dummy 3, and the drive component 5 drives the insertion component 6 to move. The moving insertion component 6 is connected to the moving component 2 under the guidance of the guide component 7, so that the drive component 5 propels the dummy 3 to move slowly through the insertion component 6 and the moving component 2. The above arrangement allows the obstacle driving platform to have both ejection and slow movement testing modes simultaneously, thereby improving the overall practicality of the obstacle driving platform; 2. Through the drive motor 504 and the drive screw Rod 501 drives drive block 502 to move. When drive block 502 moves to the predetermined position, as drive block 502 continues to move, guide rod 704 pushes plug block 604 upward through guide groove 702, so that plug block 604 can move into plug groove 606. At this time, drive block 502 can normally drive moving block 203 to move. The above setting makes it possible to automatically move plug block 604 into plug groove 606 by only driving drive block 502, which makes it more convenient to change the way the dummy moves.
