[0031] 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.
[0032] The purpose of this utility model is to provide a chassis structure and a new energy sanitation vehicle, which provides physical protection for the battery through upper and side protective devices, and at the same time increases the connection strength between the battery and the vehicle frame, so that the chassis structure has a higher safety factor.
[0033] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0034] Please refer to Figure 1-10 The chassis structure and new energy sanitation vehicle disclosed in this utility model embodiment include: a frame 1, a battery bracket, an upper protective device 2, and a side protective device 3. The battery bracket is installed on one side of the frame 1, the upper protective device 2 is disposed above the battery bracket and connected to the frame 1, and the side protective device 3 is disposed on the side of the battery bracket away from the frame 1 and connected to the upper protective device 2 and the battery bracket. The upper protective device 2 and the side protective device 3 can isolate the battery bracket from external obstacles, forming physical protection for the battery placed on the battery bracket, effectively avoiding the problem of collision or scratches caused by direct contact between the battery and obstacles. At the same time, the interconnected upper protective device 2 and the side protective device 3 are equivalent to an intermediate connecting structure, increasing the connection points between the battery bracket and the frame 1, so that the battery bracket can provide more stable support for the battery, improving the safety of the chassis structure, and thus improving the safety factor of the new energy sanitation vehicle using this chassis structure.
[0035] like Figure 1As shown, the specific connection method of the frame 1, the upper protective device 2 and the side protective device 3 is as follows: one side of the upper protective device 2 is directly connected to the frame 1, the other side of the upper protective device 2 is connected to the side protective device 3, and the side protective device 3 is connected to the battery bracket at a position away from the upper protective device 2.
[0036] As a preferred embodiment, the chassis structure also includes a telescopic structure. The side protection device 3 is connected to the upper protection device 2 and the battery bracket respectively through the telescopic structure. Furthermore, the telescopic structure can extend or retract in a direction away from or towards the frame 1. In the prior art, the loading mechanism of a pure electric compressed garbage truck is located at the rear of the vehicle, requiring the width of the left and right sides of the chassis to be the same. The loading mechanism of a pure electric kitchen waste truck is located on the right side of the vehicle, requiring the width of the right side of the chassis to be narrower than the width of the left side. Therefore, existing chassis on the market cannot simultaneously realize the modification of the above two types of sanitation vehicles. The setting of the telescopic structure allows the side protection device 3 to extend or retract in a direction away from or towards the frame 1. When it is necessary to modify into a pure electric kitchen waste truck, the side protection device 3 moves towards the frame 1 under the action of the telescopic structure, so that the width of the right side of the chassis is narrower than the width of the left side. When it is necessary to modify into a pure electric compressed garbage truck, the side protection device 3 is not adjusted to keep the width of the two sides of the chassis the same, so that the chassis structure can support the modification of different types of sanitation vehicles and improve the applicability of the chassis structure.
[0037] Of course, as needed, those skilled in the art can install protective devices 1 and side protective devices 2 on both sides of the vehicle frame.
[0038] Furthermore, the telescopic structure includes a first adjusting rod 4 and a second adjusting rod 5. The first adjusting rod 4 is located on the upper part of the side protection device 3, and a plurality of first connecting holes 6 are provided at the end of the first adjusting rod 4 away from the side protection device 3. The first connecting holes 6 are arranged sequentially along the extension direction of the first adjusting rod 4. The second adjusting rod 5 is located on the lower part of the side protection device 3, and a plurality of second connecting holes 7 are provided at the end of the second adjusting rod 5 away from the side protection device 3. The second connecting holes 7 are arranged sequentially along the extension direction of the second adjusting rod 5. When it is necessary to adjust the position of the side protection device 3, it is only necessary to replace the first connecting hole 6 connected to the upper protection device 2 and the second connecting hole 7 that cooperates with the battery bracket to realize the extension or retraction of the side protection device 3, thereby improving the convenience of adjusting the side protection device 3.
[0039] Furthermore, the upper protective device 2 has a first mounting hole on the side away from the frame 1 that mates with the first connecting hole 6, and the battery bracket has a second mounting hole on the side away from the frame 1 that mates with the second connecting hole 7.
[0040] Preferably, the first connecting hole 6 is connected to the first mounting hole by a bolt structure, and the second connecting hole 7 is connected to the second mounting hole by a bolt structure.
[0041] Furthermore, the first adjusting rod 4 and the second adjusting rod 5 are set horizontally.
[0042] In a preferred embodiment, the telescopic structure includes a first telescopic slide rail and a second telescopic slide rail. The track of the first telescopic slide rail is installed on the upper part of the side protection device 3, and the slider of the first telescopic slide rail is correspondingly installed on the side of the upper protection device 2 near the side protection device 3. The track of the second telescopic slide rail is installed on the lower part of the side protection device 3, and the slider of the second telescopic slide rail is correspondingly installed on the side of the battery bracket near the side protection device 3. The track of the first telescopic slide rail and the slider are in sliding cooperation, and the track of the second telescopic slide rail and the slider are in sliding cooperation. When it is necessary to adjust the position of the side protection device 3, the side protection device 3 is pulled outward or pushed inward. Both the track of the first telescopic slide rail and the slider of the second telescopic slide rail can slide outward or inward relative to the slider of the first telescopic slide rail and the slider of the second telescopic slide rail.
[0043] Preferably, a locking mechanism is provided between the track of the first telescopic slide rail and / or the slider, so as to lock the track and the slider when needed, so that the side protection mechanism can be held in a fixed position.
[0044] In a preferred embodiment, the upper protective device 2 is provided with a connector 8, which is vertically arranged. One end of the connector 8 is connected to the upper protective device 2, and the other end of the connector 8 is connected to the battery bracket; this further strengthens the connection between the battery bracket and the vehicle frame 1.
[0045] Preferably, there are two connectors 8, which are respectively located at both ends of the upper protective device 2 on the side near the frame 1.
[0046] Furthermore, connector 8 is connected to the battery bracket using bolts.
[0047] In a preferred embodiment, the upper protective device 2 is further provided with a reinforcing part 13, one end of which is connected to the upper protective device 2, and the other end of which is connected to the longitudinal beam of the frame 1.
[0048] Even better, the reinforcing part 13 is connected to the longitudinal beam of the frame 1 by bolts.
[0049] In a preferred embodiment, the upper protective device 2 includes a first frame, which is composed of multiple longitudinal rods and multiple transverse rods connected together. The side protective device 3 includes a second frame, which is composed of multiple longitudinal rods and multiple transverse rods connected together. The frame-type first and second frames have the advantages of structural stability and light weight, which can reduce the total weight of the side protective device and the upper protective device while protecting the battery.
[0050] Furthermore, reinforcing ribs are provided at the intersections of longitudinal and transverse members.
[0051] More preferably, the upper protective device 2 further includes a first skin 9, which matches the first frame and covers the side of the first frame away from the battery bracket. The side protective device 3 further includes a second skin 10, which matches the second frame and covers the side of the second frame away from the battery bracket. The arrangement of the first skin 9 and the second skin 10 achieves isolation of small foreign objects such as stones and branches, avoids the adverse effects of small foreign objects on the battery, and improves the protection effect of the battery.
[0052] Furthermore, the first skin 9 and the first frame, and the second skin 10 and the second frame are connected by bolts.
[0053] Furthermore, welding nuts are pre-embedded on both the first skin 9 and the second skin 10, and holes corresponding to the welding nuts are provided on the first frame and the second frame.
[0054] In a preferred embodiment, a third skin 11 is also included. One edge of the third skin 11 is connected to the upper edge of the second skin 10. The third skin 11 extends towards the frame 1 and partially overlaps with the first skin 9. The third skin 11 and the first skin 9 are in sliding engagement. Specifically, when the width of the right side is the same as the width of the left side, the overlap area between the third skin 11 and the first skin 9 is small. When the width of the right side is narrower than the width of the left side, the overlap area between the third skin 11 and the first skin 9 is larger. This allows the chassis structure to be applied to different scenarios and improves the applicability of the chassis structure.
[0055] This utility model also discloses a new energy sanitation vehicle, which uses the above-mentioned chassis structure.
[0056] In a preferred embodiment, an extension portion 12 is provided on one side of the upper protective device 2 and / or the side protective device 3. The extension portion 12 extends away from the battery bracket along the length direction of the new energy sanitation vehicle. An extension skin is provided on the extension portion 12 to shorten the distance between the upper protective device 2 and / or the side protective device 3 and the wheel, thereby effectively increasing the effective protection area of the upper protective device 2 and / or the side protective device 3. Preferably, the distance between the extension portion 12 on the side protective device 3 and the rear wheel is less than 300mm.
[0057] Even better, the extended portion 12 is provided with a connecting structure 20 for connecting to the frame 1.
[0058] As a preferred embodiment, the new energy sanitation vehicle also includes a cab 14, a front axle 15, a rear axle 16, a powertrain 17, an air tank 18, and a spare tire 19.
[0059] Furthermore, the powertrain 17 includes components such as an electric motor, a gearbox, and a drive shaft.
[0060] Even better, there are three air tanks 18, which are installed on the front and rear crossbeams of the rear axle 16 inside the frame 1; the spare tire 19 is located in the middle of the rear of the frame 1.
[0061] In a preferred embodiment, the first skin 9, the second skin 10, and the third skin 11 are all made of aluminum patterned plate.
[0062] It is understandable that battery packs can be installed on both sides of the frame 1.
[0063] Any adaptive changes made according to actual needs are within the protection scope of this utility model.
[0064] It should be noted that, for those skilled in the art, it is obvious that this utility model is not limited to the details of the above exemplary embodiments, and that this utility model can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered as exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description.
