Description

A sensor mounting base for an unmanned vehicle chassis Technical Field

[0001] This utility model relates to the technical field of unmanned vehicles, specifically to an unmanned vehicle chassis sensor mounting base. Background Technology

[0002] As autonomous driving technology matures, the deployment of driverless vehicles is becoming increasingly feasible. Sensors in low-speed driverless vehicles are mainly used to assist intelligent algorithms in achieving functions such as road perception and path planning. The sensors equipped on driverless vehicles (including lidar, millimeter-wave radar, cameras, ultrasonic radar, etc.) are significantly more advanced than those in ordinary vehicles. As algorithms continue to develop and improve, various sensors are also constantly evolving.

[0003] According to Chinese patent CN220180689U, an unmanned vehicle sensor mounting bracket includes a base plate that can be mounted on an unmanned vehicle. A ring plate is fixedly connected to the base plate, and the inner side of the ring plate is threaded, through which a position sensor is threadedly connected. The base plate is provided with multiple movable inverted L-shaped support rods, which surround the outer ring of the position sensor and can rotate on their own. Multiple mounting holes are also provided on the support rods. When the vertical support rods are changed from being perpendicular to the base plate to being parallel, an integrated bracket can be formed, and other types of sensors can be installed through the mounting holes.

[0004] In the above solution, by providing threads inside the ring plate and then connecting it to the position sensor via these threads, the following disadvantages arise: the size of the ring plate is fixed during use, which makes it impossible to meet the installation requirements of position sensors of different sizes and specifications, resulting in a reduction in the flexibility and practicality of the device. Summary of the Invention

[0005] The purpose of this invention is to provide a sensor mounting base for an unmanned vehicle chassis, in order to solve the problem that the fixed size of the ring plate in the mounting bracket cannot meet the installation requirements of position sensors of different sizes and specifications, resulting in a reduction in the flexibility and practicality of the device.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: an unmanned vehicle chassis sensor mounting base, including a mounting base, the mounting base being disposed on the bottom surface of a position sensor, the top surface of the mounting base having a plurality of movable slots, the plurality of movable slots being symmetrically arranged, movable plates being movably disposed inside the plurality of movable slots, springs being fixed to the outer sides of the plurality of movable plates, the outer ends of the plurality of springs being fixedly connected to the inner walls of the plurality of movable slots, and arc-shaped clamping plates being fixed to the top surfaces of the plurality of movable plates.

[0007] Preferably, the inner walls of the plurality of movable slots are provided with sliding grooves on both sides, and the outer walls of the plurality of movable plates are fixed with sliders on both sides, and the two sliders are respectively slidably disposed in the two sliding grooves.

[0008] Preferably, a fixing plate is fixed to the outer side of each of the movable plates, and two first threaded holes are respectively opened on the top surface of each of the fixing plates. A first bolt is threaded into each of the two first threaded holes, and the bottom end of each of the two first bolts contacts the top surface of the mounting base.

[0009] Preferably, a second threaded hole is provided on one side of each of the several movable plates, and a second bolt is threaded into each of the several second threaded holes.

[0010] Preferably, an arc-shaped rubber pad is fixed to the inner side of each of the arc-shaped clamps, and a rubber block is fixed to the inner end of each of the second bolts.

[0011] Preferably, the top surface of the mounting base is provided with a plurality of third threaded holes, and a third bolt is threaded into each of the plurality of third threaded holes.

[0012] Compared with existing technologies, the sensor mounting base for an unmanned vehicle chassis that adopts the above technical solution has the following advantages:

[0013] First, in use, the combination of mounting base, movable slot, movable plate, spring and arc-shaped clamp plate helps to meet the installation requirements of position sensors of different sizes and specifications, thereby improving the flexibility and practicality of the device.

[0014] Second, during use, the cooperation of the sliding groove and the slider helps to limit the movement of the movable plate, preventing it from shifting or wobbling, thereby improving the stability of the movable plate during movement. The first bolt, through its abutment against the top surface of the mounting base, effectively limits and fixes the positions of the fixed plate, movable plate, and arc-shaped clamping plate, preventing them from moving during subsequent use, thus improving the firmness and reliability of the position sensor installation;

[0015] Third, secondary fixation of the position sensor during use improves its stability after installation. When the arc-shaped clamp holds the position sensor, the arc-shaped rubber pad directly contacts the outer surface of the sensor, effectively buffering the clamping pressure and preventing damage from excessive rigid compression. It also increases the friction between the clamp and the sensor, making the clamping more stable. Similarly, the rubber block also prevents damage and increases friction. The use of the third threaded hole and the third bolt facilitates the installation of the mounting base onto the unmanned vehicle chassis (not shown in the figure). Attached Figure Description

[0021] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] As shown in Figures 1-4, an unmanned vehicle chassis sensor mounting base includes a mounting base 1. The mounting base 1 is disposed on the bottom surface of a position sensor 2. The position sensor 2 is an existing structure, which can be referred to in Chinese Patent Publication No. CN2201 80689U. The position sensor 2 in this application is the same as the position sensor in the referenced document. The top surface of the mounting base 1 is provided with a plurality of movable slots 3, which are symmetrically arranged. Movable plates 4 are movably disposed inside the plurality of movable slots 3. Springs 5 ​​are fixed to the outer sides of the plurality of movable plates 4. The outer ends of the plurality of springs 5 ​​are fixedly connected to the inner walls of the plurality of movable slots 3. Arc-shaped clamps 6 are fixed to the top surfaces of the plurality of movable plates 4.

[0023] In use, the operator first moves several movable plates 4 outwards, distancing them from each other. At this time, the spring 5 is compressed, storing elastic potential energy. Then, the position sensor 2 is placed on the top surface of the mounting base 1, ensuring it is precisely within the space enclosed by the movable plates 4. The movable plates 4 are then released, and under the action of the elastic potential energy stored in the spring 5, the spring 5 begins to return to its original shape, thus automatically resetting the movable plates 4. As the movable plates 4 reset, the movable plates 4 and the arc-shaped clamps 6 fixed on them move closer together until they are tightly fitted against the outside of the position sensor 2, achieving a stable clamping and fixing of the position sensor 2, thereby completing the installation operation of the position sensor 2. The mounting base 1 is then installed on the unmanned vehicle chassis (not shown in the figure). The coordinated use of the mounting base 1, movable slot 3, movable plates 4, spring 5, and arc-shaped clamps 6 facilitates the installation of position sensors 2 of different sizes, thereby improving the flexibility and practicality of the device.

[0024] As shown in Figures 1-4, sliding grooves 7 are provided on both sides of the inner wall of several movable grooves 3, and sliders 8 are fixed on both sides of the outer wall of several movable plates 4. The two sliders 8 are slidably arranged in the two sliding grooves 7 respectively.

[0025] In use, the cooperation between the slide groove 7 and the slider 8 helps to limit the movement of the movable plate 4, preventing it from shifting or shaking, thereby improving the stability of the movable plate 4 during movement.

[0026] As shown in Figures 1-4, a number of movable plates 4 are respectively fixed with fixed plates 9 on their outer sides. The top surfaces of the fixed plates 9 are respectively provided with two first threaded holes 10. The two first threaded holes 10 are respectively threaded with first bolts 11. The bottom ends of the two first bolts 11 are respectively in contact with the top surface of the mounting base 1. The sides of the movable plates 4 are respectively provided with second threaded holes 12. The two second threaded holes 12 are respectively threaded with second bolts 13.

[0027] During use, after the arc-shaped clamping plate 6 initially fixes the position sensor 2, the operator needs to rotate the first bolt 11. As the first bolt 11 rotates, it gradually moves downward until its bottom end is in close contact with the top surface of the mounting base 1. At this point, the first bolt 11 effectively limits and fixes the positions of the fixed plate 9, the movable plate 4, and the arc-shaped clamping plate 6 through the abutment action with the top surface of the mounting base 1, preventing them from moving during subsequent use, thereby improving the firmness and reliability of the position sensor 2 installation. After several arc-shaped clamping plates 6 have completed the initial fixation of the position sensor 2, the operator can further strengthen the fixing effect by rotating the second bolt 13. When the second bolt 13 rotates in the corresponding second threaded hole 12, it gradually moves towards the position sensor 2 until it is in close contact with the outer surface of the position sensor 2, thereby achieving secondary fixation of the position sensor 2 and improving the stability of the position sensor 2 after installation.

[0028] As shown in Figures 1-4, several arc-shaped clamps 6 are respectively fixed with arc-shaped rubber pads 14 on their inner sides, several second bolts 13 are respectively fixed with rubber blocks 15 on their inner ends, and several third threaded holes 16 are opened on the top surface of the mounting base 1, and several third bolts 17 are respectively threaded into the several third threaded holes 16.

[0029] During use, when the arc-shaped clamping plate 6 clamps the position sensor 2, the arc-shaped rubber pad 14 can directly contact the outer surface of the position sensor 2, effectively buffering the clamping pressure of the arc-shaped clamping plate 6 on the position sensor 2, preventing the position sensor 2 from being damaged by excessive rigid compression. At the same time, it can also increase the friction between the arc-shaped clamping plate 6 and the position sensor 2, making the clamping more stable. Similarly, the rubber block 15 can also avoid damage and increase friction. The cooperation of the third threaded hole 16 and the third bolt 17 makes it easy for the operator to install the mounting base 1 on the unmanned vehicle chassis (not shown in the figure).

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
