Description

Technical Field

[0001] This utility model belongs to the field of electric patrol vehicle technology, specifically a protective device for electric patrol vehicles. Background Technology

[0002] Electric patrol vehicles are a type of vehicle specifically designed for personnel in special departments to use for patrols, in order to improve the safety and efficiency of electric patrol vehicles;

[0003] Patrol vehicles are a type of shuttle bus, typically powered by electric batteries, making them environmentally friendly, pollution-free, and resource-efficient. They feature a personalized control system, flexible steering, comfortable handling, smooth and easy operation, simple driving, reusable electric power, and a long lifespan. Patrol vehicles are widely used in hotels, scenic spots, real estate sales vehicles, factories, airports, and other locations.

[0004] However, when existing electric patrol vehicles travel on complex terrain, the ground easily scrapes against the chassis. Since the chassis houses the battery pack, damage to the battery pack can cause the vehicle to lose power. Furthermore, the existing battery pack protective plate is directly fixed to the chassis and fits snugly against the vehicle body. When passing over high protrusions, the plate is prone to deformation, which in turn damages the battery pack.

[0005] Therefore, a protective device for electric patrol vehicles is proposed to address the above problems. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides a protective device for electric patrol vehicles. This device protects the battery pack of the electric patrol vehicle, preventing the battery pack protective plate from being directly fixed to the chassis during use, thus preventing damage to the battery pack when the protective plate deforms.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an electric patrol vehicle protection device, comprising an electric patrol vehicle body, wherein a chassis protection component is installed on the surface of the electric patrol vehicle body;

[0008] The chassis protection assembly includes a heat dissipation protection plate. A heat dissipation protection plate is installed at the battery pack of the electric patrol vehicle body. A baffle is slidably connected inside the heat dissipation protection plate. Connecting plates are symmetrically installed at the bottom of the electric patrol vehicle body. A movable rod is rotatably connected between the two connecting plates. An arc-shaped connecting plate is installed on the surface of the movable rod. The arc-shaped connecting plate is located on the bottom surface of the baffle. A limit adjustment assembly is installed on the surface of the electric patrol vehicle body.

[0009] Preferably, hinge blocks are symmetrically installed on one side surface of the arc-shaped connecting plate, and connecting rods are hinged to the surface of the hinge blocks. An adjusting block is slidably connected in the groove opened on the bottom surface of the baffle, and the adjusting block is hinged to one end of the connecting rod.

[0010] Preferably, a guide rod is slidably connected in the through hole on the surface of the adjusting block, and both ends of the guide rod pass through the adjusting block and are installed in the groove on the surface of the baffle.

[0011] Preferably, a return spring is sleeved on the surface of the guide rod, one end of the return spring is connected to the adjusting block, and the other end of the return spring is installed in a groove opened on the surface of the baffle.

[0012] Preferably, a torsion spring is fitted at both ends of the movable rod that passes through the connecting plate, with one end of the torsion spring connected to the movable rod and the other end of the torsion spring connected to the connecting plate.

[0013] Preferably, the limiting adjustment component includes mounting blocks, the mounting blocks are symmetrically mounted on the surface of the baffle, the surface of the heat dissipation and protection plate is provided with a guide groove, a limiting rod is slidably connected inside the guide groove, one end of the limiting rod passes through the guide groove and is connected to the mounting blocks.

[0014] Preferably, a limiting plate is installed at the other end of the limiting rod, and the diameter of the limiting plate is adapted to the guide groove.

[0015] Preferably, a second reset spring is sleeved on the surface of the limiting rod, one end of the second reset spring is connected to the limiting plate, and the other end of the second reset spring is installed inside the guide groove.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This utility model incorporates a chassis protection component. When the electric patrol vehicle travels on complex terrain, the ground presses against the arc-shaped connecting plate. As the arc-shaped connecting plate moves upward, it pushes the adjusting block through the hinge block and connecting rod to slide within the groove on the baffle surface. As the baffle moves, it seals the baffle and the heat dissipation protection plate, thus protecting the battery pack of the electric patrol vehicle. This prevents the battery pack protection plate from being directly fixed to the chassis during use, ensuring that the battery pack is not damaged when the protection plate deforms.

[0018] 2. This utility model incorporates a limit adjustment component. When the baffle slides inside the heat dissipation protective plate, the baffle, via the mounting block, drives the limit rod to slide within the guide groove on the surface of the heat dissipation protective plate. During the sliding process, the limit rod is limited by the limit plate to prevent it from disengaging from the guide groove. As the limit plate moves, it causes the second return spring to deform, thus resetting the position of the baffle. This allows the electric patrol vehicle to reset the baffle after it reaches a normal road surface, greatly improving the device's effectiveness and limiting the baffle's movement to prevent positional deviation during movement.

[0025] 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.

[0026] like Figures 1 to 5 As shown, this utility model provides a protective device for an electric patrol vehicle, including an electric patrol vehicle body 1, and a chassis protection component 2 installed on the surface of the electric patrol vehicle body 1.

[0027] The chassis protection component 2 includes a heat dissipation protection plate 21. The heat dissipation protection plate 21 is installed at the battery pack of the electric patrol vehicle body 1. A baffle 22 is slidably connected inside the heat dissipation protection plate 21. Connecting plates 23 are symmetrically installed at the bottom of the electric patrol vehicle body 1. A movable rod 24 is rotatably connected between the two connecting plates 23. An arc-shaped connecting plate 25 is installed on the surface of the movable rod 24. The arc-shaped connecting plate 25 is located on the bottom surface of the baffle 22. A limit adjustment component 3 is installed on the surface of the electric patrol vehicle body 1.

[0028] Specifically, such as Figure 1 As shown, hinge blocks 26 are symmetrically installed on one side surface of the arc-shaped connecting plate 25. A connecting rod 27 is hinged to the surface of the hinge block 26. An adjusting block 28 is slidably connected in a groove opened on the bottom surface of the baffle 22. The adjusting block 28 is hinged to one end of the connecting rod 27. A guide rod 29 is slidably connected in a through hole opened on the surface of the adjusting block 28. Both ends of the guide rod 29 pass through the adjusting block 28 and are installed in the groove opened on the surface of the baffle 22. A return spring 210 is sleeved on the surface of the guide rod 29. One end of the return spring 210 is connected to the adjusting block 28, and the other end of the return spring 210 is installed in the groove opened on the surface of the baffle 22. A torsion spring 211 is sleeved on both ends of the movable rod 24 that passes through the connecting plate 23. One end of the torsion spring 211 is connected to the movable rod 24, and the other end of the torsion spring 211 is connected to the connecting plate 23.

[0029] In this implementation scheme: When the electric patrol vehicle body 1 travels on complex terrain, the ground presses against the arc-shaped connecting plate 25. The arc-shaped connecting plate 25, under pressure, rotates between the two connecting plates 23 via the movable rod 24. During rotation, the movable rod 24 causes the torsion spring 211 to deform, and the torsion spring 211 assists the movable rod 24 in resetting, thereby further improving the device's effectiveness. As the arc-shaped connecting plate 25 moves upward, it pushes the adjusting block 28 to slide within the groove on the surface of the baffle 22 via the hinge block 26 and connecting rod 27. During this sliding process, the adjusting block 28 pushes the baffle 22 to slide inside the heat dissipation and protection plate 21. As the adjusting block 28 moves, it... The guide rod 29 slides on the surface of the guide rod 29, which guides the position of the adjusting block 28 and prevents the adjusting block 28 from shifting position during movement. At this time, the adjusting block 28 compresses the return spring 210, causing the return spring 210 to deform. The return spring 210 can reset the position of the adjusting block 28, thereby further improving the effectiveness of the device. As the baffle 22 moves continuously, the baffle 22 and the heat dissipation protection plate 21 are sealed, thereby protecting the battery pack of the electric patrol vehicle body 1. This prevents the battery pack protection plate of the electric patrol vehicle 1 from being directly fixed to the chassis during use, so that the battery pack will not be damaged when the protection plate deforms.

[0030] Please refer to Example 2 Figures 1-5 The difference between this embodiment and embodiment 1 is that the limiting adjustment component 3 includes a mounting block 31, the mounting block 31 is symmetrically mounted on the surface of the baffle 22, the surface of the heat dissipation protection plate 21 is provided with a guide groove 32, the inside of the guide groove 32 is slidably connected to a limiting rod 33, one end of the limiting rod 33 passes through the guide groove 32 and is connected to the mounting block 31.

[0031] Specifically, such as Figure 1-5 As shown, a limiting plate 34 is installed at the other end of the limiting rod 33. The diameter of the limiting plate 34 is adapted to the guide groove 32. A second reset spring 35 is sleeved on the surface of the limiting rod 33. One end of the second reset spring 35 is connected to the limiting plate 34, and the other end of the second reset spring 35 is installed inside the guide groove 32.

[0032] In this implementation scheme: when the baffle 22 slides inside the heat dissipation protective plate 21, the baffle 22 drives the limiting rod 33 to slide within the guide groove 32 on the surface of the heat dissipation protective plate 21 via the mounting block 31. During the sliding process, the limiting rod 33 is limited by the limiting plate 34 to prevent it from disengaging from the guide groove 32. As the limiting plate 34 moves, it causes the second return spring 35 to deform. The second return spring 35 can reset the position of the baffle 22, thereby enabling the electric patrol vehicle 1 to reset the baffle 22 after driving onto a normal road surface. This greatly improves the effectiveness of the device and limits the movement of the baffle 22, preventing it from shifting position during movement.

[0033] It should be noted that the electric patrol vehicle body 1 inside the device is a mature existing technology.
