Description

Technical Field

[0001] This utility model relates to the field of unmanned electric patrol vehicles, specifically an unmanned electric patrol vehicle with a protective device. Background Technology

[0002] With societal development, security tasks in large industrial parks, factories, airports, docks, exhibition halls, and other public places are becoming increasingly important. Unmanned electric patrol vehicles have been widely used as crucial monitoring and security tools for both police and civilian purposes, and possess a vast market potential.

[0003] According to Chinese Patent No. CN218640980U, an unmanned electric patrol vehicle with a protective device is disclosed. This utility model has a protective mechanism, which is set up in two sets and installed on both sides of the electric patrol vehicle. By utilizing the anti-collision and buffering effect of the protective mechanism, the electric patrol vehicle is protected against collisions during daily patrols, avoiding damage caused by repeated impacts. This effectively implements protective measures for the unmanned electric patrol vehicle and improves its stability and durability.

[0004] Regarding the aforementioned patent content, an airbag is incorporated to cushion the impact force generated when colliding with hard objects. However, since the airbag is in direct contact with hard objects, it may be damaged after repeated impacts. Furthermore, the airbag may rupture if it directly collides with a sharp object. Therefore, the airbag needs to be replaced after damage. However, because the airbag is mounted on a mounting plate, which is attached to a mounting frame via springs and dampers, even if the airbag is damaged but the springs and dampers are not, the entire protective structure must be disassembled for replacement. This makes it difficult to replace the airbag individually, resulting in high replacement costs and reducing the effectiveness of airbag replacement. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide an unmanned electric patrol vehicle with a protective device to solve the technical problem that it is inconvenient to replace the airbag separately when the airbag is damaged.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an unmanned electric patrol vehicle with a protective device, comprising an electric patrol vehicle body and two mounting plates. Each of the two mounting plates is provided with a disassembly and assembly assembly, which includes a slot on one side of the mounting plate, a threaded post on the other side of the mounting plate, and two cavities inside the mounting plate. An insert plate is inserted into the slot, and slots are provided on the outer surface and back of the insert plate. A movable plate is provided inside the cavity, and a retaining plate extending into the slot is installed on the movable plate. A movable sleeve and a limiting sleeve are respectively fitted onto the outer wall of the threaded post. A connecting plate is installed on the outer surface and back of the movable sleeve, and a push plate penetrating into the cavity is fixed on one side of the connecting plate. A pressure plate is connected to the push plate and the movable plate through a rotating shaft.

[0007] By adopting the above technical solution, when the push plate moves into the cavity, it will push the pressure plate to rotate. The pressure plate can then push the movable plate to move and drive the locking plate to move, so that the locking plate is locked into the slot, thereby achieving the purpose of locking and limiting the insertion plate.

[0008] Furthermore, mounting brackets are bolted to both sides of the electric patrol vehicle body, a damper is installed at the middle position of one side of the mounting bracket, and a mounting plate is installed at one end of the damper.

[0009] By adopting the above technical solution, when the mounting plate is impacted and moves towards the mounting frame, it will squeeze the damper, which can then buffer the impact force and improve the protection effect on the electric patrol vehicle body.

[0010] Furthermore, a plurality of guide rods penetrating the mounting frame are fixed on one side of the mounting plate, and one end of each guide rod is connected to a limit block.

[0011] By adopting the above technical solution, the guide rod can be moved when the mounting plate moves, thereby improving the stability of the mounting plate during movement.

[0012] Furthermore, multiple springs are installed between the mounting plate and the mounting bracket, and the guide rod is located inside the springs.

[0013] By adopting the above technical solution, when the mounting plate moves towards the mounting bracket, it will squeeze the spring, causing the spring to be compressed and thus playing a buffering role.

[0014] Furthermore, the inner wall of the cavity is provided with a sliding groove, and a slider is provided inside the sliding groove, the slider being fixedly connected to the push plate.

[0015] By adopting the above technical solution, when the push plate moves, it can drive the slider to slide inside the groove, thereby improving the stability of the push plate when it moves.

[0016] Furthermore, the assembly / disassembly assembly also includes a through-hole on one side of the mounting bracket, the height of which is greater than the diameter of the threaded post and the limiting sleeve.

[0017] By adopting the above technical solution, the threaded post can pass through the opening, thus avoiding obstruction of the movement of the mounting plate.

[0018] Furthermore, the inner wall of the limiting sleeve is provided with threads, and the limiting sleeve is threadedly connected to the threaded column.

[0019] By adopting the above technical solution, the limiting sleeve can move on the threaded column when rotating, and when the limiting sleeve is in contact with the movable sleeve, the limiting sleeve can tighten and limit the movable sleeve.

[0020] Furthermore, an airbag is installed on one side of the insert plate, and the airbag is detachably connected to the mounting plate via the insert plate.

[0021] By adopting the above technical solution, when disassembling the airbag, the insert plate needs to be pulled upwards to remove it from the slot, so that the airbag can be removed for replacement.

[0022] Furthermore, the insert plate is adapted to the slot, and the card plate is adapted to the card slot.

[0023] By adopting the above technical solution, the airbag can be positioned after the insert plate is inserted into the slot, thus facilitating the installation of the airbag.

[0024] Furthermore, the card plate is slidably connected to the cavity via a movable plate.

[0025] By adopting the above technical solution, the card plate can be moved into the cavity. After the card plate is removed from the slot, the insertion plate is no longer positioned, and the insertion plate can be taken out upwards.

[0026] In summary, the present invention has the following main advantages:

[0027] 1. This utility model features a disassembly and assembly component. When the airbag is damaged due to repeated impacts or direct collision with a sharp object, requiring replacement, the operator can rotate the limiting sleeve to move it away from the movable sleeve, then pull the movable sleeve to move it towards the limiting sleeve. The movable sleeve then moves the push plate, which in turn pulls the pressure plate to rotate. The pressure plate then pulls the movable plate, causing the locking plate to move out of the slot and no longer lock the insert plate. The insert plate can then be pulled upwards to remove it from the slot, allowing the airbag to be removed for replacement. The new airbag can then be installed... The insert plate on the airbag is inserted into the slot. Then, the movable sleeve is pushed to move, which in turn drives the push plate to move into the cavity. This causes the pressure plate to push the movable plate to reset and move, and also causes the locking plate to move, so that the locking plate is locked into the slot, achieving the purpose of locking and limiting the insert plate. Then, the limiting sleeve is rotated in the opposite direction, so that the limiting sleeve and the movable sleeve are pressed together. In this way, the installation of the airbag can be completed. This method allows for quick installation and removal of the airbag, and only the airbag and insert plate need to be replaced. There is no need to disassemble the entire protective mechanism for replacement, thereby saving replacement costs and improving the efficiency of airbag installation and removal.

[0028] 2. This utility model has a limiting sleeve, which can tighten and limit the movable sleeve to prevent it from moving at will and ensure that the card plate can be firmly inserted into the card slot, thereby improving the stability of the airbag after installation.

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0038] The embodiments of this utility model will be described below based on its overall structure.

[0039] Example 1:

[0040] An unmanned electric patrol vehicle with protective devices, such as Figures 1-7 As shown, the system includes an electric patrol vehicle body 1 and two mounting plates 8. Each mounting plate 8 is equipped with a disassembly and assembly component 9. Mounting brackets 2 are bolted to both sides of the electric patrol vehicle body 1. A damper 3 is installed at the middle of one side of the mounting bracket 2, and a mounting plate 8 is installed at one end of the damper 3. When the mounting plate 8 is impacted and moves towards the mounting bracket 2, it will squeeze the damper 3. The damper 3 can then buffer the impact force and improve the protection effect of the electric patrol vehicle body 1. Multiple guide rods 6 are fixed to one side of the mounting plate 8, penetrating the mounting bracket 2. One end of the guide rod 6 is connected to a limit block 5. When the mounting plate 8 moves, it can drive the guide rods 6 to move, thereby improving the stability of the mounting plate 8 when it moves.

[0041] See Figures 1-5The disassembly and assembly component 9 includes a slot 903 on one side of the mounting plate 8, a threaded post 914 on the other side of the mounting plate 8, and two cavities 901 inside the mounting plate 8. An insert plate 902 is inserted into the slot 903, and slots 905 are provided on the outer surface and back of the insert plate 902. A movable plate 906 is disposed inside the cavity 901, and a retaining plate 904 extending into the slots 905 is mounted on the movable plate 906. An airbag 7 is installed on one side of the insert plate 902. The airbag 7 is detachably connected to the mounting plate 8 via the insert plate 902. When removing the airbag 7, the insert plate 902 must be pulled upwards, allowing it to exit the slot 903. Remove the airbag 7 so that it can be replaced. The insert plate 902 is adapted to the slot 903, and the card plate 904 is adapted to the card slot 905. When the insert plate 902 is inserted into the slot 903, the airbag 7 can be positioned, which facilitates the installation of the airbag 7. The card plate 904 is slidably connected to the cavity 901 through the movable plate 906 so that the card plate 904 can be moved into the cavity 901. When the card plate 904 is removed from the card slot 905, the insert plate 902 is no longer positioned. At this time, the insert plate 902 can be taken out upward. The top of the insert plate 902 is fixed with a handle, which makes it easy for the staff to pull the insert plate 902 upward.

[0042] Specifically, a movable sleeve 912 and a limiting sleeve 913 are respectively fitted onto the outer wall of the threaded column 914. The inner wall of the limiting sleeve 913 is threaded, and the limiting sleeve 913 is threadedly connected to the threaded column 914. The outer wall of the limiting sleeve 913 is provided with anti-slip texture to facilitate the movement of the limiting sleeve 913 on the threaded column 914 when it is rotated. When the limiting sleeve 913 is in contact with the movable sleeve 912, the limiting sleeve 913 can press and limit the movable sleeve 912. A connecting plate 911 is installed on the outer surface and back of the movable sleeve 912, and a push plate 908 that penetrates into the cavity 901 is fixed on one side of the connecting plate 911. The push plate 908 and the movable sleeve 912 are connected to the threaded column 914. A pressure plate 907 is connected between the movable plates 906 via a rotating shaft. When the push plate 908 moves into the cavity 901, it pushes the pressure plate 907 to rotate. The pressure plate 907 then pushes the movable plate 906 to move and drives the locking plate 904 to move, so that the locking plate 904 is locked into the slot 905, thereby achieving the purpose of locking and limiting the insertion plate 902. A sliding groove 909 is provided on the inner wall of the cavity 901, and a slider 910 is provided inside the sliding groove 909. The slider 910 is fixedly connected to the push plate 908. When the push plate 908 moves, it can drive the slider 910 to slide inside the sliding groove 909, thereby improving the stability of the push plate 908 when it moves.

[0043] Example 2:

[0044] Based on the above embodiment 1, when the mounting plate 8 is impacted, it will move. In order to improve the buffering effect against the impact force, the following structure will be set.

[0045] Specifically, multiple springs 4 are installed between the mounting plate 8 and the mounting bracket 2. The guide rod 6 is located inside the spring 4. When the mounting plate 8 moves towards the mounting bracket 2, it will squeeze the spring 4, causing the spring 4 to be compressed, so as to play a buffering role and improve the protection effect on the electric patrol vehicle body 1.

[0046] Example 3:

[0047] Based on the above embodiment 1, when the mounting plate 8 is impacted, it will move and drive the threaded post 914 to move. In order to prevent the mounting bracket 2 from blocking the movement of the threaded post 914, the following structure will be set.

[0048] See Figures 1-4 The disassembly and assembly component 9 also includes a through-hole 915 opened on one side of the mounting bracket 2. The height of the through-hole 915 is greater than the diameter of the threaded post 914 and the limiting sleeve 913. The through-hole 915 corresponds to the threaded post 914 so that the threaded post 914 can pass through the through-hole 915 to avoid obstructing the movement of the mounting plate 8.

[0049] The working principle of this utility model is as follows: First, the staff can install the mounting bracket 2 on both sides of the electric patrol vehicle body 1 with bolts. When the electric patrol vehicle body 1 hits a hard object during daily patrol, the airbag 7 is compressed by force. At the same time, the mounting plate 8 will move under the impact force and squeeze the damper 3 and spring 4. With the cooperation of the airbag 7, damper 3 and spring 4, buffer protection can be performed to avoid the unmanned electric patrol vehicle being damaged by repeated impacts. Thus, the unmanned electric patrol vehicle can be protected.

[0050] When airbag 7 is damaged due to repeated impacts or direct collision with a sharp object, it needs to be replaced. The operator can rotate the limiting sleeve 913 away from the movable sleeve 912, then pull the movable sleeve 912 towards the limiting sleeve 913. The movable sleeve 912 then moves the push plate 908, which in turn pulls the pressure plate 907 to rotate. The pressure plate 907 then pulls the movable plate 906 to move. At this point, the locking plate 904 will move out of the slot 905 and will no longer lock the insert plate 902. Then, the insert plate 902 can be pulled upwards to move it from the slot 905. Remove the airbag 7 from the slot 3. Then, insert the insert plate 902 on the new airbag 7 into the slot 903. Next, push the movable sleeve 912 to move. The movable sleeve 912 will drive the push plate 908 to move into the cavity 901, which will cause the pressure plate 907 to push the movable plate 906 to reset and move the locking plate 904. The locking plate 904 will then be locked into the slot 905, thus locking and limiting the insert plate 902. Then, rotate the limiting sleeve 913 in the opposite direction so that the limiting sleeve 913 and the movable sleeve 912 are pressed together to limit the movable sleeve 912. This completes the installation of the airbag 7.
