Detailed Implementation

[0038] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0039] Example 1

[0040] like Figures 1-6 The present invention provides a specific embodiment of an automatic anti-thrust device for an explosion-proof electric vehicle battery box, which includes at least two sets of anti-thrust mechanisms. At least one set of anti-thrust mechanisms is provided on both the left and right sides of the battery box. As a preferred embodiment, in order to ensure the stability of the battery box and the vehicle frame installation, four anti-thrust mechanisms are provided in this embodiment, with two anti-thrust mechanisms provided on the left and right sides of the battery box respectively.

[0041] See Figures 1 to 6 In this embodiment, the thrust-stopping mechanism includes a base plate 1 fixedly mounted on the vehicle frame, a locking pin positioning assembly 3 mounted on the left or right side of the battery box via a connecting plate 2, a mating pin hole 4, a locking gap 5, and a locking block 6. Specifically, the mating pin hole 4 is formed on the base plate 1 for mating with the locking pin positioning assembly 3. The locking gap 5 is located between the mating pin hole 4 and the locking pin positioning assembly 3, i.e., the gap between the mating pin hole 4 and the locking pin positioning assembly 3. The locking block 6 mates with the locking gap 5, and the locking block 6 moves vertically and horizontally following the moving assembly 7 mounted on the connecting plate 2.

[0042] In this embodiment, a base plate with mating pin holes 4 is installed on the vehicle frame, and a locking pin positioning assembly 3 is installed on the battery box via a connecting plate 2. The precise positioning of the battery box on the vehicle frame is achieved by the cooperation between the positioning block 33 and the mating pin holes 4. When the vehicle is started and emergency braking occurs, the battery box moves in the direction of travel due to inertia, and the locking block 6 falls into the locking gap 5 under its own gravity, thereby achieving automatic anti-push of the battery box. This solves the problem of battery movement caused by the large gap of the battery box in the prior art, and avoids the safety hazard of battery box impact during emergency braking of the vehicle.

[0043] like Figure 2 and Figure 4 As shown, the movable component 7 in this embodiment includes a surrounding plate 71 fixedly mounted on the connecting plate 2, a sliding block 72, and a sliding cavity 73 formed by the surrounding plate 71 and the connecting plate 2. The sliding block 72 slides vertically within the sliding cavity 73, and a locking block 6 is fixedly disposed on the lower end face of the sliding block 72. See also Figure 5 and Figure 6When the connecting plate 2 follows the battery box to move horizontally on the vehicle frame, the sliding block 72 moves horizontally under the action of the surrounding plate 71, when the vehicle suddenly brakes, the locking block 6 moves above the locking gap 5, the sliding block 72 slides downward along the sliding cavity 73 under the action of its own gravity, so as to realize the locking action of the locking block 6.

[0044] The locking pin positioning assembly 3 in this embodiment includes a vertical sleeve 31 fixedly installed with the connecting plate 2, a locking pin 32 cooperatively installed in the vertical sleeve 31 and rotationally cooperated with the vertical sleeve 31, and a positioning block 33 fixedly arranged with the vertical sleeve 31 and used for installation cooperation with the cooperating pin hole 4. An upper end surface of the locking pin 32 is provided with a handle 34 used for blocking the vertical movement of the battery box. It is further explained that, in order to realize the smooth entry of the locking block 6 into the locking gap 5, an avoiding space 8 used for avoiding the positioning block 33 is arranged at the connection between the sliding block 72 and the locking block 6. The arrangement of the avoiding space 8 also makes the locking block 6 not fall off from below the locking gap 5 when the locking block 6 falls into the locking gap 5, so as to ensure the stability between the locking block 6 and the locking gap 5.

[0045] As a preferred embodiment, the connecting plate 2 is integrally arranged with the vertical sleeve 31, so as to ensure the stability of the connection of the vertical sleeve 31 relative to the battery box.

[0046] As shown in Figure 4 , the positioning block 33 in the first embodiment is a rectangular positioning block 33, the cooperating pin hole 4 is a rectangular hole, and the corresponding locking block 6 includes a rectangular body 61 and a first inclined portion 62 arranged at a lower portion of the rectangular body 61. When the locking block 6 slides downward into the locking gap 5, the inclined portion is used for sliding downward guidance. The arrangement of the first inclined portion 62 avoids the occurrence of the situation that the locking block 6 is stuck with the edge of the cooperating pin hole 4, so that the locking block 6 cannot smoothly enter into the cooperating pin hole 4.

[0047] The use process is as follows: specifically refer to Figure 5 and Figure 6 , when the quick change mechanism of the external device or manual pushes the battery box from the tail of the vehicle to the position of the cooperating pin hole 4 along the guide rail, the part of the rectangular positioning block 33 arranged at the lower end of the locking pin positioning assembly 3 arranged on the battery box falls into the cooperating pin hole 4, as shown in the initial state of Figure 5 , the handle 34 on the locking pin 32 is rotated, and the battery box is locked on the vehicle frame. When the vehicle is started, when the vehicle is braked in an emergency, at this time, the battery box moves to the moving direction due to inertia, that is, the locking block 6 moves to the moving direction, and under the action of the gravity of the locking block 6, falls downward into the gap between the positioning block 33 and the cooperating pin hole 4, that is, the locking gap 5, as shown in the thrust state of Figure 6 , so as to realize the automatic thrust of the battery box.

[0048] Embodiment two

[0049] The main difference between the second embodiment and the first embodiment is that the positioning block 33 in the second embodiment is a circular positioning block 33, the matching pin hole 4 is a circular hole, and the corresponding locking block comprises a crescent-shaped body and a second inclined portion arranged at the lower part of the crescent-shaped body, wherein the second inclined portion has the same effect as the first inclined portion 62, and will not be described in detail here.

[0050] The first embodiment and the second embodiment ingeniously fill the large gap, i.e., the locking gap 5, between the matching pin hole 4 and the locking pin positioning assembly 3 with the locking block, thereby ensuring the positional stability of the battery box in the driving direction. The utility model does not need to set four guide angle steels matched with the large gap of the battery box. When installing, the battery box can be pushed into the installation from the tail of the frame, and the installation space of the battery box does not need to be reserved above the frame, so that the installation of the battery box is more convenient. Meanwhile, the utility model ingeniously adopts the handle 34 arranged on the upper end surface of the locking pin 32 to press on the upper end surface of the battery box, thereby preventing the movement of the battery box in the up-down direction on the frame. The structure is simple, automatic thrust is prevented, and the utility model has a good application market.

[0051] It should be understood that the specific embodiments described above are only used to explain the utility model, and are not used to limit the utility model. The obvious changes or variations derived from the spirit of the utility model are still within the protection scope of the utility model.
