Description

Technical Field

[0001] This utility model relates to the field of parking space guidance device testing technology, specifically a parking space guidance device testing and experimental device. Background Technology

[0002] Parking guidance devices are intelligent systems used to guide vehicles to quickly find available parking spaces in a parking lot. By detecting the status of parking spaces, processing data, and displaying guidance information, they help car owners park efficiently and improve parking lot management efficiency. According to the requirements of CJ / T 429-2013 "Parking Guidance Devices for Garages and Parking Lots", parking guidance devices need to be tested.

[0003] In existing testing technologies for parking guidance devices, multiple parameters need to be tested for the cooperation between the parking space detector and the reflector. However, traditional testing methods have obvious drawbacks: the reflector installation structure is complex, and it is often fixed by bolts or snap-fit ​​splicing, which makes the installation process cumbersome and time-consuming. Moreover, the height of the reflector is difficult to adjust flexibly after installation, and it cannot quickly adapt to the needs of different testing scenarios. This not only increases the difficulty of testing operations, but also reduces the overall testing efficiency, becoming a key issue restricting the development of parking guidance device testing technology.

[0004] Therefore, a testing device for parking guidance devices is needed to solve the problems of complex installation of the reflector structure and difficulty in adjusting its height after installation in the testing process of existing parking guidance devices. Utility Model Content

[0005] The purpose of this invention is to provide a testing device for parking space guidance devices, so as to solve the problems of complex installation of the reflector structure and difficulty in adjusting the height after installation in the testing process of parking space guidance devices in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a parking space guidance device testing device, comprising a base and a movable vehicle mounted on the base, wherein a reflector is mounted on the top of the movable vehicle, and the movable vehicle is provided with an installation mechanism and an adjustment component;

[0007] The installation mechanism includes an installation block mounted on the top surface of the mobile vehicle, a slot on the top surface of the installation block, a U-shaped cavity inside the installation block, and a servo motor mounted on the front end of the installation block. A bidirectional lead screw is rotatably connected between the two end walls inside the transverse section of the U-shaped cavity. Two symmetrically distributed threaded sleeves are threaded onto the bidirectional lead screw. Movable plates are slidably installed inside the two vertical sections of the U-shaped cavity. Connecting rods are rotatably installed between the two threaded sleeves and the two movable plates on both sides. A guide groove is opened on the bottom surface inside the transverse section of the U-shaped cavity. Two symmetrically distributed guide blocks are slidably installed in the guide groove. Multiple evenly distributed locking rods are installed on the adjacent side of the two movable plates.

[0008] It should be noted in the solution that the adjustment component includes an electric push rod embedded in one side of the roof of the mobile vehicle and two parallel guide rods installed on the other side of the roof of the mobile vehicle. The outer surfaces of the two guide rods are slidably fitted with sliding sleeves, and the two sliding sleeves are each fitted with a fixing rod between them and the mounting block.

[0009] It is worth noting that a parking space detector is installed on one side of the vertical section of the base, and a guide rail for moving vehicles is provided on the top surface of the horizontal section of the base.

[0010] Furthermore, it should be noted that the slot is equipped with a plug, and both sides of the plug have locking slots that correspond to and fit with the multiple locking rods.

[0011] In a preferred embodiment, the output end of the servo motor is coaxially connected to the front end of the bidirectional lead screw, and the two guide blocks are respectively connected to the two threaded sleeves.

[0012] In a preferred embodiment, the output end of the electric actuator is connected to the mounting block via a connector, and the insert block is connected to the reflector.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] A servo motor drives a bidirectional lead screw to rotate, which in turn drives two threaded sleeves to move away from each other, thereby causing two moving plates to move closer together. This allows the two moving plates to insert a locking rod into the locking slot, enabling rapid installation of the reflector. An electric push rod pushes the mounting block to move the reflector upward, adjusting its height. This effectively avoids the problems of complex installation of the reflector structure and difficulty in adjusting its height after installation during the testing and experimentation of the parking guidance device.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example: Figures 1-5 As shown, this utility model provides a technical solution, including a base 1 and a mobile vehicle 4 movably mounted on the base 1. A reflector 5 is mounted on the top of the mobile vehicle 4, and an installation mechanism 6 and an adjustment component 7 are provided on the mobile vehicle 4.

[0023] The mounting mechanism 6 includes a mounting block 61 mounted on the top surface of the mobile vehicle 4, a slot 62 opened on the top surface of the mounting block 61, a U-shaped cavity 63 opened inside the mounting block 61, and a servo motor 64 mounted on the front end of the mounting block 61. A bidirectional lead screw 65 is rotatably connected between the two end walls inside the transverse section of the U-shaped cavity 63. Two symmetrically distributed threaded sleeves 66 are threadedly connected to the bidirectional lead screw 65. Movable plates 67 are slidably installed inside the two vertical sections of the U-shaped cavity 63. Connecting rods 68 are rotatably installed between the two threaded sleeves 66 and the two movable plates 67 on both sides. A guide groove 69 is opened on the bottom surface inside the transverse section of the U-shaped cavity 63. Two symmetrically distributed guide blocks 610 are slidably installed in the guide groove 69. Multiple evenly distributed locking rods 611 are installed on the side of the two movable plates 67 that are close to each other. The locking rods 611 can be slidably inserted into the slot 62.

[0024] Specifically, after inserting the plug 8 on the bottom surface of the reflector 5 into the slot 62, the servo motor 64 is started to drive the bidirectional lead screw 65 to rotate. The bidirectional lead screw 65 drives the two threaded sleeves 66 to move away from each other. During the movement of the threaded sleeves 66, the two moving plates 67 are pulled closer to each other, so that when the two moving plates 67 move, they drive the locking rod 611 to insert into the locking slot 9 to lock the plug 8, thereby completing the quick installation of the reflector 5. Similarly, the reverse operation can realize the quick disassembly of the reflector 5.

[0025] Further as Figure 1 and Figure 2 As shown, it is worth noting that the adjustment assembly 7 includes an electric push rod 71 embedded in one side of the top surface of the mobile vehicle 4 and two parallel guide rods 72 installed on the other side of the top surface of the mobile vehicle 4. The outer surfaces of the two guide rods 72 are slidably fitted with sliding sleeves 73, and fixing rods 74 are installed between the two sliding sleeves 73 and the mounting block 61.

[0026] Specifically, when it is necessary to adjust the height of the reflector 5, the electric actuator 71 is activated to push the mounting block 61 to move, so that the mounting block 61 moves upward along the guide rod 72, thereby driving the reflector 5 to move upward, thus realizing the adjustment of the height of the reflector 5.

[0027] Further as Figure 1 As shown, it is worth noting that a parking space detector 2 is installed on one side of the vertical section of the base 1, and a guide rail 3 for the movement of the mobile vehicle 4 is provided on the top surface of the horizontal section of the base 1.

[0028] Specifically, the installed parking space detector 2, together with the reflector 5, is used to conduct testing experiments on the parking space guidance device, and the set guide rail 3 is used to realize the smooth movement of the mobile vehicle 4 on the base 1.

[0029] Further as Figure 5 As shown, it is worth noting that the slot 62 is equipped with a plug 8, and both sides of the plug 8 are provided with locking slots 9 that correspond to and fit the multiple locking rods 611.

[0030] Specifically, the insertion block 8 and the slot 62 work together to achieve quick positioning when installing the reflector 5. The locking slot 9 and the locking rod 611 work together to lock the insertion block 8, thereby enabling the reflector 5 to be installed on the mobile vehicle 4.

[0031] Further as Figure 4 As shown, it is worth noting that the output end of the servo motor 64 is coaxially connected to the front end of the bidirectional lead screw 65, and the two guide blocks 610 are respectively connected to the two threaded sleeves 66.

[0032] Specifically, the output end of the servo motor 64 is coaxially connected to the front end of the bidirectional lead screw 65, which facilitates the control of the rotation of the bidirectional lead screw 65. The two guide blocks 610 are respectively connected to the two threaded sleeves 66 to guide the movement of the threaded sleeves 66.

[0033] Further as Figure 1 and Figure 5 As shown, it is worth noting that the output end of the electric actuator 71 is connected to the mounting block 61 via a connector, and the insert block 8 is connected to the reflector 5.

[0034] Specifically, the output end of the electric push rod 71 is connected to the mounting block 61 via a connector, so that the electric push rod 71 can push the mounting block 61 to move the reflector 5. The insert block 8 is connected to the reflector 5 so that the reflector 5 can be installed on the mobile vehicle 4 through the cooperation of the insert block 8 and the slot 62.

[0035] In summary: When using this testing device, after moving the base 1 to the test area, the moving carriage 4 is installed on the top surface of the transverse section of the base 1. Then, the insert 8 on the bottom surface of the reflector 5 is inserted into the slot 62. The servo motor 64 is then activated via the control panel, driving the bidirectional lead screw 65 to rotate. Under the action of the thread, the bidirectional lead screw 65 drives the two threaded sleeves 66 to move away from each other. During the movement of the two threaded sleeves 66, the two moving plates 67 are pulled closer together. During the movement, the two moving plates 67 drive the locking rod 611 to insert into the locking groove 9, locking the insert 8, thus completing the installation of the reflector 5. Finally, the moving carriage 4 slowly moves the reflector 5. The test was conducted in conjunction with the parking space detector 2 to determine the distance between the parking space detector 2 and the reflector 5 when the parking space was vacant and when the parking space was occupied. Then, the moving vehicle 4 was reset and the electric push rod 71 was activated to move the mounting block 61. The mounting block 61 moved the reflector 5 upward along the guide rod 72. The above operation was repeated to test the maximum detection angle of the parking space detector 2. The operation is simple and realizes the rapid installation and height adjustment of the reflector 5. It effectively avoids the problems of complex installation of the reflector structure and difficulty in adjusting the height after installation during the test of the parking space guidance device.

[0036] The servo motor 64 and the electric actuator 71 can be purchased from the market and are mature technologies in this field, which have been fully disclosed. Therefore, they will not be described again in the specification.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
