Detailed Description

The following detailed description of embodiments of the present invention is provided in connection with the accompanying drawings and examples. The following examples are intended to illustrate the utility model but are not intended to limit the scope of the utility model.

Referring to fig. 1 to 3, an electric motor coach (not shown) according to an embodiment of the present invention includes a frame 1, a traveling assembly 2 installed below the frame 1, and a safety arrangement structure (not shown) of an electric motor coach battery pack installed in the frame 1. The safety arrangement structure of the battery pack of the electric motor coach comprises a seat 3 installed in the coach frame 1 and a battery pack 4 installed below the seat 3. The seat 3 includes a seat tub 31 and a seat cushion (not shown) mounted on the seat tub 31, and the battery pack 4 is mounted in the seat tub 31. In the present embodiment, the seat 3 is a row seat, and the row seat is formed by integrally connecting a plurality of single seats, and has a length n times that of the single seat (n is greater than or equal to 2). Typically, there are two or three seats in a row, and accordingly the seat tub has an internal depth twice or three times that of a single seat, thereby accommodating a more bulky battery pack. The battery pack 4 is prior art and is not developed in detail here. The battery pack 4 is arranged in the seat barrel 31, so that the height of a bottom plate (not shown) of the electric motor coach can be reduced, the stepping number of getting on or off the electric motor coach is reduced, convenience and tidiness are realized, and the electric motor coach is favorable for passengers to get on or off the electric motor coach.

The walking assembly 2 comprises two pairs of wheels, each pair of wheels is arranged on the same side of the frame, and the battery pack 4 is arranged between the two wheels on the same side. In a specific embodiment, the battery pack 4 may be disposed between two wheels on one side, or may be divided into two groups and disposed between two wheels on two sides, respectively.

Specifically, the walking assembly 2 comprises a first wheel set and a second wheel set which are oppositely arranged, wherein the first wheel set is arranged on the left side of the frame 1, and the second wheel set is arranged on the right side of the frame 1. The first wheel group comprises a first front wheel 21 at the front side and a first rear wheel 22 at the rear side, and the second wheel group comprises a second front wheel 23 at the front side and a second rear wheel 24 at the rear side. When the battery pack 4 is a group, the setting mode is as follows: the battery pack is mounted between the first front wheel 21 and the first rear wheel 22, or between the second front wheel 23 and the second rear wheel 24. When there are two sets of battery packs 4, the first set of battery packs is mounted between the first front wheel 21 and the first rear wheel 22, and the second set of battery packs is mounted between the second front wheel 23 and the second rear wheel 24. Because the seats 3 between the first front wheel 21 and the first rear wheel 22 of the electric motor coach, and between the second front wheel 23 and the second rear wheel 24 are the row seats, and the battery pack 4 is arranged between the first front wheel 21 and the first rear wheel 22, and between the second front wheel 23 and the second rear wheel 24, the original design is fully utilized, so that the vehicle frame does not need to be changed, and the inner space of the seat barrel 31 on the side where the wheels are located is utilized.

Referring to fig. 4 to 6, in order to prevent the battery pack 4 from being ignited and exploded due to a side impact, the frame 1 is further provided with an anti-collision elastic member 5. In this embodiment, the frame 1 is provided with two elastic anti-collision members 5 arranged up and down, and the elastic anti-collision members 5 are made of spring steel. Specifically, the method comprises the following steps: both ends of the spring steel are installed between a vehicle side body (not shown) and a vehicle side sill (not shown), the spring steel is bent to form an arc-shaped structure, and the raised bent portion of the spring steel faces outward. The both ends of anticollision elastic component 5 are provided with mounting hole 51, mounting hole 51 can be dismantled with frame 1 through the bolt and be connected, need to explain, the bolt that this embodiment adopted belongs to screw thread type fastener, and its simple structure, connection are reliable, install and remove the convenience, belong to common fastener moreover, convenient maintenance is changed, in practical application of course, can change the fastener classification according to actual conditions, do not exemplify it one by one here, as long as reach can dismantle anticollision elastic component 5 with frame 1 and be connected can.

The anti-collision elastic part 5 is made of spring steel materials, and has the advantages of high elastic limit, high strength limit, large yield ratio, high reliability, strong anti-damping performance, heat resistance, low temperature resistance, oxidation resistance and corrosion resistance, in particular, the anti-collision elastic part 5 adopts a variable cross-section plate spring structure, has the advantages of light weight, strong reliability, simple structure and the like, the middle section of the variable cross-section plate spring structure has the largest thickness and extends towards the two ends of the variable cross-section plate spring structure, the thickness of the cross section is gradually reduced, when the electric motor coach has side collision, the variable cross-section plate spring structure utilizes the self characteristic to absorb and consume the energy generated in collision, thereby playing the role of protecting the battery pack 4 when the side of the electric motor coach is impacted, ensuring that the displacement and deformation of the battery pack 4 are reduced when the electric motor coach has the collision, and preventing the battery pack 4 from firing and explosion, thereby play the effect of protection passenger on the car, it should be noted that, in practical application, also can be according to actual conditions with crashproof elastic component 5 sets up to other materials and structure, if this crashproof elastic component 5 is the block rubber, does not carry out the one-by-one example here to it, as long as this crashproof elastic component 5 can realize the effect of protection battery package 4 when receiving the striking in [ electric ] motor coach side.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
