[0020] The drawings described herein are used to provide a further understanding of the present invention and constitute a part of the present application. The exemplary embodiments of the present invention and their descriptions are used to explain the present invention and do not constitute an improper limitation on the present invention. In the drawings:

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0024] Unless otherwise specifically stated, the relative arrangement, numerical expressions and numerical values ​​of the parts and steps set forth in these embodiments do not limit the scope of the utility model. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be considered as a part of the specification. In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0025] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" may include both "above" and "below". The device may also be positioned in other different ways, and the spatially relative descriptions used here are interpreted accordingly.

[0026] In the related art, for ordinary fuel dump trucks, most of them use the exhaust gas discharged by the engine to heat the bottom plate of the cargo box, and the application is relatively mature. However, for electric dump trucks, there is no corresponding solution for heating the bottom plate of the cargo box.

[0027] In response to this problem, the inventor discovered during the research that the drive motor of the electric dump truck will emit a large amount of heat during normal operation, so it is necessary to set up a water cooling device to cool the drive motor, so that the drive motor can operate at a reasonable working temperature. For example, in some embodiments, the cooling device of the drive motor is generally a water cooling device, and the cooling water in the water cooling device flows to the radiator for heat dissipation, and then the water pump pumps the cooling water after heat dissipation and cooling to the water cooling device to continue to cool the drive motor. Among them, the temperature of the cooling water of the water cooling device can be adjusted by adjusting the speed of the water pump to ensure that the drive motor operates at a reasonable working temperature. It can be seen that in this process, the heat generated during the operation of the drive motor will be dissipated into the air, and this part of the heat is not effectively utilized.

[0028] Based on the above findings, the utility model proposes to use the heat generated by the drive motor to heat the bottom plate of the cargo box, which can not only effectively utilize the heat generated by the drive motor, but also solve the problem of cooling the drive motor.

[0029] Reference below Figure 1 and Figure 2 The structure and working process of the electric dump truck in some embodiments of the utility model are described in detail.

[0030] refer to Figure 1 and Figure 2 The electric dump truck of some embodiments of the utility model comprises a driving motor, a cargo box 1 and a bottom plate heating pipeline 2. The driving motor is used to drive the electric dump truck to move. The cargo box 1 comprises a bottom plate 11. The bottom plate heating pipeline 2 is arranged in the inner cavity of the bottom plate 11 and a heat transfer medium flows in the bottom plate heating pipeline 2. The heat transfer medium is configured to absorb the heat generated during the operation of the driving motor and heat the bottom plate 11.

[0031] The electric dump truck of the embodiment of the utility model is provided with a bottom plate heating pipeline 2 on the bottom plate 11 of the cargo box 1, and a heat transfer medium flows in the bottom plate heating pipeline 2. The heat transfer medium absorbs the heat generated during the operation of the driving motor and heats the bottom plate 11. In this way, the temperature of the bottom plate 11 is increased, which effectively improves the problem that clay is easily adhered to the bottom plate in severe cold weather, thereby reducing the manual scraping of the adhered clay and improving the working efficiency.

[0032] refer to Figure 2In some embodiments, the electric dump truck further includes a cooling device 5 disposed at the drive motor to cool the drive motor. The cooling device 5 is in fluid communication with the bottom plate heating pipeline 2. The heat transfer medium flows in the cooling device 5 to absorb the heat generated during the operation of the drive motor and flows into the bottom plate heating pipeline 2 to release the heat. That is, the bottom plate heating pipeline 2 of this embodiment is formed as a radiator of the cooling device 5.

[0033] The cooling device 5 is arranged on one side of the driving motor to absorb the heat generated by the driving motor. The heat transfer medium in the cooling device 5 absorbs the heat and its temperature rises. Then, the heat transfer medium flows into the bottom plate heating pipeline 2 to release heat to heat the bottom plate 11. In this way, the heat of the driving motor can be effectively utilized.

[0034] In some embodiments, the electric dump truck further includes a driving pump 3. The driving pump 3 is in fluid communication with the cooling device 5 and the bottom plate heating pipeline 2 to pump the heat transfer medium in the cooling device 5 into the bottom plate heating pipeline 2. The driving pump 3 is used to pump the heat transfer medium from the cooling device 5 into the bottom plate heating pipeline 2, which can not only speed up the flow rate of the heat transfer medium, but also control the flow rate of the heat transfer medium by adjusting the rotation speed of the driving pump 3.

[0035] In some embodiments, the inlet 21 of the bottom plate heating pipeline 2 is in fluid communication with the driving pump 3. The outlet 22 of the bottom plate heating pipeline 2 is in fluid communication with the cooling device 5. The heat transfer medium absorbs the heat dissipated by the driving motor in the cooling device 5 to increase its temperature, and then the driving pump 3 pumps the heated heat transfer medium in the cooling device 5 into the bottom plate heating pipeline 21 to release heat to heat the bottom plate, and the temperature of the heat transfer medium after releasing heat decreases, and then returns to the cooling device 5 to absorb heat.

[0036] In some embodiments, the electric dump truck further includes a temperature regulating device 4 disposed between the cooling device 5 and the bottom plate heating pipeline 2. The temperature regulating device 4 is used to continue heating the heat transfer medium output by the cooling device 5. The driving pump 3 is used to pump the heat transfer medium further heated by the temperature regulating device 4 into the bottom plate heating pipeline 2. Figure 2 As shown by the arrows, the flow path of the heat transfer medium is as follows: the heat transfer medium flows out of the cooling device 5 and enters the temperature control device 4 to continue heating, and then flows into the bottom plate heating pipeline 2 through the driving pump 3 to heat the bottom plate. The heat transfer medium flowing out of the bottom plate heating pipeline 2 returns to the cooling device 5 to absorb heat again.

[0037] In some embodiments, the electric dump truck also includes a temperature control device 4 arranged between the cooling device 5 and the bottom plate heating pipeline 2 and a temperature sensor arranged at the outlet 22 of the bottom plate heating pipeline 2. The temperature sensor is used to measure the temperature of the heat transfer medium flowing out from the outlet of the bottom plate heating pipeline 2. When the temperature of the heat transfer medium at the outlet is higher than the set temperature, the temperature control device 4 cools down the heat transfer medium; when the temperature of the heat transfer medium at the outlet is lower than the set temperature, the temperature control device 4 heats up the heat transfer medium.

[0038] In order to prevent the high temperature of the heat transfer medium entering the cooling device 5 from affecting the cooling effect on the drive motor, a temperature sensor is provided at the outlet of the bottom plate heating pipeline 2. When the temperature of the heat transfer medium detected by the temperature sensor is higher than the set temperature, the temperature regulating device 4 is used to cool the heat transfer medium. When the temperature of the heat transfer medium at the outlet is lower than the set temperature, the temperature regulating device 4 is used to heat the heat transfer medium.

[0039] In some embodiments, the temperature control device 4 may be a refrigeration device. The refrigeration device has both refrigeration and heating functions. In other embodiments, the temperature control device 4 is an electric heating device.

[0040] In some embodiments, the electric dump truck further includes a flow path C disposed between the driving pump 3 and the cooling device 5, an on-off valve 6 disposed on the flow path C, and a temperature control device 4. The on-off valve 6 is used to control the on-off of the flow path C. The flow path C is used when the ambient temperature is low and the driving motor cannot start normally. At this time, the temperature control device 4 can be controlled to heat the heat transfer medium, and the on-off valve 6 can be controlled to open, and then the driving pump 3 pumps the heated heat transfer medium into the cooling device 5 for heating the driving motor. When the temperature of the driving motor rises and reaches the starting condition, the driving motor starts working normally, and the on-off valve 6 is closed.

[0041] Specifically, for example, the temperature of the heat transfer medium of the cooling device can be monitored in real time. When the temperature is low, the on-off valve 6 is opened; when the temperature is high, the on-off valve 6 is opened.

[0042] refer to Figure 1 In some embodiments, the bottom plate heating pipes 2 are evenly distributed within the coverage area of ​​the bottom plate 11 .

[0043] In some embodiments, the bottom plate heating pipeline 2 is distributed in a serpentine shape.

[0044] In some embodiments, the heat transfer medium includes water.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for protection of the utility model.
