Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all 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.

[0024] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "inner", "outer", "front end", "rear end", "both ends", "one end", "the other end", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0025] In the description of the present utility model, it should be noted that unless otherwise clearly defined and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0026] The present utility model provides a Figures 1-3 range-extended new energy electric truck as shown, including a battery compartment housing 1 fixedly installed on the vehicle frame and a hatch door 2 for closing the hatch of the battery compartment housing 1. The hatch door 2 is a gull-wing door. By opening or closing the hatch door 2 with this structure, the locking of the hatch door 2 is safer and more stable, and the cost is also lower.

[0027] The hatch faces the side of the vehicle. Inside the battery compartment housing 1, a plurality of slots 3 are separated by partitions, and the plurality of slots 3 are arranged in layers, with at least one slot 3 in each layer. According to the driver's needs, the required number of battery packs can be inserted into the stacked slots. Due to the characteristic that the thickness of the battery pack is much smaller than the width of the battery pack, the traditional battery compartment laid on the vehicle frame chassis is designed as a stacked structure, which solves the problem that the number of battery packs in traditional electric vehicles is limited by the vehicle length. By adopting the stacked battery compartment structure, the number of slots 3 and the number of battery packs that can be inserted can be safely and effectively increased. The number of battery packs on one side is expanded from at most 6 on one side to about 9 on one side, increasing the range, ensuring the vehicle's performance, and reducing the coverage area and the probability of bump damage.

[0028] The battery compartment housing 1 is arranged between the front of the vehicle 5 and the cargo box. The battery compartment housing 1 and the truck bed 4 are an integrated structure. On the one hand, the installation stability and safety of the battery compartment housing 1 are ensured, and on the other hand, the integrity of each part of the vehicle can be improved, and the appearance is more beautiful.

[0029] The battery compartment housing 1 is provided with a temperature control channel 6 connected to each slot 3, and the temperature control channel 6 is connected to the temperature control device pipeline through the connection port 10. When the battery pack is charging and discharging, in order to ensure the safety of the battery pack and improve the charging and discharging efficiency, it may be necessary to perform a heating or cooling operation. At this time, the temperature control device outputs cold or hot air, which enters the temperature control channel 6 in the middle of the battery compartment housing 1, and enters the slot 3 where each battery pack is located through the temperature control channel 6 to exchange heat with the battery pack, ensuring that it is in the best working state and extending the life of the battery cell.

[0030] A bracket assembly 11 is provided at the bottom of the slot 3 to raise the lower surface of the battery pack and form a gap between the supporting surface. The battery pack is raised by the bracket assembly 11, thereby increasing the contact area with the airflow and enhancing the heat exchange efficiency, thereby achieving the effect of adjusting the battery pack temperature faster.

[0031] The support assembly 11 can be two strips supporting the long sides of the battery pack. After the battery pack is inserted into the slot 3, the space behind and below the battery pack is connected. The edges of the battery pack are supported by the two strips to lift it up, while the middle is separated from the plane where it is located, and the space behind and below is connected, which further facilitates air flow and enhances heat exchange efficiency.

[0032] In addition, the temperature control device can use the air conditioner in the cockpit, so there is no need to add additional refrigeration and heat exchange equipment, saving space and reducing costs after modification.

[0033] It also disclosed Figure 4 The extended-range new energy electric truck shown includes a plurality of independent single battery compartments 7 and a compartment cover 8 for opening and closing the compartment openings of the single battery compartments 7, the compartment openings facing the side of the vehicle, and the plurality of single battery compartments 7 are relatively fixedly installed in a stacked manner, and each layer is provided with at least one single battery compartment 7. Since the single battery compartments 7 can be freely disassembled and assembled, the number of single battery compartments 7 can be arbitrarily increased according to actual use requirements, thereby increasing or decreasing the number of battery packs that can be inserted, and compared with the structure of a fixed-size battery compartment, the degree of customization is higher.

[0034] The electric truck further includes a flow guiding box 9. One end of each of a plurality of single battery compartments 7 away from the compartment opening is communicated with the flow guiding box 9, and the flow guiding box 9 is communicated with the temperature control device through a connection port 10. When adding a single battery compartment 7, the newly added single battery compartment 7 is relatively fixed to the lower single battery compartment 7, and the newly added single battery compartment 7 is conducted with the flow guiding box 9. Cold or hot flow is output by the temperature control device and enters the flow guiding box 9, and then enters the interior of each single battery compartment 7 through the flow guiding box 9 to exchange heat with the battery pack, so as to achieve the technical effect of adjusting the temperature of the battery pack.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
