DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below. Apparently, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figure 1 - Figure 3 In this embodiment, a lightweight vehicle body bottom reinforcement plate is provided, which includes a mounting plate 1 installed at the bottom of the vehicle chassis 8. A buffer plate 2 is provided at the bottom of the mounting plate 1. The buffer plate 2 includes a bottom plate 21 and inclined side plates 22 hinged on both sides of the bottom plate 21. When there is no collision with an obstacle, the bottom plate 21, the mounting plate 1, and the two inclined side plates 22 form an isosceles trapezoid as a whole, and the length of the bottom plate 21 is less than the length of the mounting plate 1. A number of first buffer members 3 are installed between the inclined side plate 22 and the mounting plate 1, and the first buffer members 3 are slidably connected to the mounting plate 1. A number of second buffer members 4 are installed between the bottom plate 21 and the mounting plate 1, and the second buffer members 4 are slidably connected to the bottom plate 21;

[0021] A sliding seat 5 is hinged on the side of the inclined side plate 22 away from the bottom plate 21, and the sliding seat 5 is slidably arranged at the bottom of the mounting plate 1. The cooperation of the inclined side plate 22, the bottom plate 21, the first buffer member 3, and the second buffer member 4 can cope with the situation where an obstacle directly impacts the inclined side plate 22 or directly impacts the bottom plate 21, avoiding the problem of the chassis being directly impacted, and being able to reduce the shock degree of the chassis.

[0022] Specifically, referring to Figure 1 and Figure 3 the first buffer member 3 includes an arc-shaped telescopic rod 31 fixed to the inclined side plate 22. The center of the arc-shaped telescopic rod 31 is located on the hinge axis of the inclined side plate 22 and the sliding seat 5. A connection block 32 slidably matched with the mounting plate 1 is fixed to the top of the arc-shaped telescopic rod 31, and a first spring 33 is sleeved on the arc-shaped telescopic rod 31.

[0023] Specifically, referring to Figure 1 and Figure 3 the second buffer member 4 includes a linear telescopic rod 41 vertically fixed to the bottom of the mounting plate 1. A second spring 42 is installed on the outer periphery of the linear telescopic rod 41. A support block 43 slidably connected to the bottom plate 21 is fixed to the bottom end of the linear telescopic rod 41. Further, a trapezoidal slide rail 211 is fixed to the top of the bottom plate 21, and a dovetail chute 431 matching the trapezoidal slide rail 211 is provided at the bottom of the support block 43.

[0024] Referring to Figure 1 - Figure 3 U-shaped frames 61 are fixed to both sides of the mounting plate 1. Both ends of the sliding seat 5 are slidably connected to the U-shaped frames 61, and a plurality of third springs 62 are installed between the sliding seat 5 and the U-shaped frames 61.

[0025] The following further introduces how the embodiments of the present application protect the vehicle chassis 8 in combination with specific usage scenarios. When the vehicle is moving, if an obstacle directly impacts the bottom plate 21 when it bounces up and then falls, the force of the obstacle on the bottom plate 21 will cause the bottom plate 21 to move towards the mounting plate 1 and compress the second spring 42; at the same time, the inclination angles of the inclined side plates 22 on both sides become smaller, and at this time the inclined side plates 22 will rotate, thereby causing the arc-shaped telescopic rod 31 to shorten, and further causing the second spring 42 to be compressed; at the same time, as the inclination angle of the inclined side plates 22 becomes smaller, the inclined side plates 22 will push the sliding seat 5 to slide, thereby compressing the third spring 62; thus, when the bottom plate 21 is directly impacted, through the cooperation of the bottom plate 21 and the first compression spring, the inclined side plates 22 and the second compression spring, and the third compression spring, the impact force received by the bottom plate 21 can be buffered in sequence, reducing the impact force received by the bottom plate 21, thereby protecting the vehicle chassis 8 and reducing the risk of damage to the vehicle chassis 8.

[0026] Further, an introduction is given here on why the second buffer 4 is slidably connected to the bottom plate 21: When the vehicle is moving, if an obstacle directly impacts the inclined side plate 22 when it falls after being jolted up, the force received by the inclined side plate 22 at this time will cause the bottom plate 21 to move in the horizontal direction. If the second buffer 4 is fixedly connected to the bottom plate 21, specifically, the linear telescopic rod 41 is fixedly connected to the bottom plate 21, this may cause a break between the bottom plate 21 and the linear telescopic rod 41 after the inclined side plate 22 is directly impacted by the obstacle, reducing the connection strength between the bottom plate 21 and the mounting plate 1 and also reducing the overall service life of the reinforcement plate. By slidably connecting the second buffer 4 to the bottom plate 21, specifically, a trapezoidal guide rail is fixedly connected to the bottom plate 21, and a dovetail chute 431 that fits the trapezoidal guide rail is provided on the support block 43, and the sliding fit between the second buffer 4 and the bottom plate 21 is achieved through the cooperation of the trapezoidal guide rail and the dovetail chute 431, which will not affect the normal deformation of the second spring 42 and will not damage the overall connection strength of the reinforcement plate. Specifically, when the obstacle directly impacts the inclined side plate 22, the instantaneous impact force will cause the sliding seat 5 on the impacted side to also translate, stretching the third spring 62, and at the same time, causing a relative translation between the bottom plate 21 and the second buffer 4. Then, driven by the other inclined side plate 22, the sliding seat 5 on the other side is pushed to move, compressing the third spring 62 on the other side; when the inclined side plate 22 is impacted by the obstacle, the impacted inclined side plate 22 will rotate around its hinge axis with the sliding seat 5, compressing the first compression spring and at the same time raising the height of the bottom plate 21, further compressing the second spring 42; as the obstacle passes by the inclined side plate 22 and transitions to the bottom of the bottom plate 21, the bottom plate 21 rises again, further compressing the second spring 42. In this way, under the action of the first spring 33 and the second spring 42, the impact received by the inclined side plate 22 is buffered, reducing the impact strength received by the inclined side plate 22, protecting the vehicle chassis 8, reducing the shock intensity of the vehicle chassis 8, and reducing the risk of damage to the vehicle chassis 8. In addition, when the inclined side plate 22 is directly impacted, a relative displacement occurs between the bottom plate 21 and the second buffer 4. However, due to the setting of the third spring 62, after the vehicle passes through the obstacle, the bottom plate 21 will return to its original position, ensuring the more stable use of the reinforcement plate.

[0027] Here, it also needs to be explained the functions of using the linear telescopic rod 41 and the arc telescopic rod 31. The main function of the linear telescopic rod 41 is to restrict the deformation process of the second spring 42, ensuring that the second spring 42 will not have a bending problem and ensuring the service life of the second spring 42; while the arc telescopic rod 31 is used to restrict the deformation of the first spring 33, ensuring that the elastic force of the first spring 33 on the inclined side plate 22 is perpendicular to the inclined side plate 22, improving the buffering effect.

[0028] In addition, both sides of the bottom plate 21 are hinged with inclined side plates 22, and the bottom plate 21, the two inclined side plates 22, and the mounting plate 1 are installed in an isosceles trapezoid pattern. This is because when using a car in daily life, the car may move forward or reverse by engaging the reverse gear. Obstacles may be encountered during both of these driving processes. Therefore, it is designed as an isosceles trapezoid to address the problem of the chassis encountering obstacles when the car moves forward or backward.

[0029] Referring to Figure 1 and Figure 3 , a number of second buffer members 4 are distributed in multiple rows, and each row is provided with a plurality of second buffer members 4 arranged in a linear array. In this way, after the bottom plate 21 is impacted, the buffer and shock absorption effect can be improved, thereby enhancing the protection effect on the vehicle chassis 8.

[0030] Referring to Figure 2 and Figure 3 , as a specific implementation manner of the embodiment of the present application, a plurality of mounting grooves 212 are formed in the bottom of the bottom plate 21, and rollers 7 are rotatably connected in the mounting grooves 212.

[0031] Combined with the specific usage scenario, the use of the rollers 7 can change the friction between the obstacle and the bottom plate 21 from sliding friction to rolling friction, which can make it more convenient to cross the obstacle and reduce the damage to the bottom plate 21 caused by the obstacle.

[0032] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and without departing from the spirit or basic characteristics of the present utility model, the present utility model can be implemented in other specific forms. Therefore, in any aspect, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, it is intended to encompass all changes falling within the meaning and scope of the equivalent elements of the claims in the present utility model.
