Detailed Implementation

[0029] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0030] In this disclosure, an XY coordinate system is established for the cockpit body, where the X direction is the second direction, i.e., the width direction of the vehicle, and the Y direction is the first direction, i.e., the height direction of the vehicle. Unless otherwise stated, directional terms such as "inner" and "outer" refer to the inner and outer contours relative to the component or structure itself. Furthermore, it should be noted that terms such as "first" and "second" are used to distinguish one element from another and do not have sequential or importance implications. Additionally, in the description with reference to the accompanying drawings, the same reference numerals in different drawings denote the same element.

[0031] like Figures 1 to 8As shown, the first aspect of this disclosure provides a cockpit assembly 100, including a cockpit body 10 and a power battery 20. The power battery 20 is disposed on the cockpit body 10 and includes battery cells 221 and a battery casing 21 for housing the battery cells 221. The battery casing 21 forms at least a portion of the sidewalls of the cockpit body 10, thereby integrating the power battery 20 onto the cockpit body 10. This eliminates the frame used for mounting the power battery 20 in related technologies, reducing the overall vehicle weight.

[0032] In some embodiments, the battery housing 21 is used to form at least part of the rear sidewall 12 of the cab body 10, that is, the power battery 20 can be integrated into the rear sidewall 12 of the cab body 10. In the related art, the rear-mounted power battery installation form of trucks requires a more complex and heavy frame to fix the power battery 20, which occupies the space of the vehicle's cargo box 200. In this disclosure, the power battery 20 is integrated into the rear sidewall 12 of the cab body 10, which can reduce the occupation of the rear space of the vehicle and avoid encroaching on the space of the vehicle's cargo box 200 compared with the related art.

[0033] In some embodiments, the battery housing 21 includes a tray 211 and a cover 212, the tray 211 being fastened to the cover 212 to form a first receiving space 70 for receiving the battery cell 221, the tray 211 serving to form at least a portion of the rear sidewall 12 of the cockpit body 10.

[0034] In the above-described embodiments, the tray 211 is used to form at least part of the rear sidewall 12 of the cab body 10. It can also be understood that the power battery 20 is integrated into the rear sidewall 12 of the cab body 10, eliminating the frame used to fix the power battery 20 in the rear-mounted power battery installation form in the related technology. On the one hand, it reduces the weight of the whole vehicle, and on the other hand, it reduces the occupation of the rear space of the vehicle and avoids encroaching on the space of the cargo box 200 of the vehicle.

[0035] like Figure 2 As shown, the vehicle includes a driver's cab assembly 100 and a cargo box 200. The driver's cab assembly 100 includes a driver's cab body 10 and a power battery 20. The power battery 20 is integrated into the driver's cab body 10. The driver's cab body 10 and the tray 211 of the power battery 20 form a first accommodating space 70, which is used to accommodate the driver. The tray 211 and the cover 212 form a passenger compartment 11, which is used to accommodate battery cells 221. The integration of the power battery 20 into the driver's cab body 10 reduces the space occupied by the power battery 20 in the rear of the driver's cab and avoids encroaching on the space of the cargo box 200.

[0036] In some implementations, such as Figures 4 to 6As shown, a heat exchange assembly 23 is also provided in the first accommodating space 70. The heat exchange assembly 23 includes a plurality of heat exchange plates 231 spaced apart in the first accommodating space 70 along a first direction. The plurality of heat exchange plates 231 extend along a second direction perpendicular to the first direction. The heat exchange plates 231 are all fixedly connected to the tray 211. The battery cell 221 is disposed between two adjacent heat exchange plates 231 so that the heat exchange plates 231 support the battery cell 221 in the first direction.

[0037] In the above embodiments, the heat exchange plate 231 can support the battery cell 221 on the one hand, and exchange heat with the battery cell 221 on the other hand. The fixed connection between the heat exchange plate 231 and the tray 211 includes, but is not limited to, welding, bolt connection, etc.

[0038] In some embodiments, the heat exchange plate 231 is welded to the tray 211, which can also improve the structural strength of the tray 211.

[0039] In some embodiments, the heat exchange assembly 23 further includes a substrate 232, a plurality of heat exchange plates 231 are fixedly connected to one end of the substrate 232 in a second direction, an accommodating space 71 is formed between two adjacent heat exchange plates 231 and the substrate 232, and a plurality of battery cells 221 are stacked in the accommodating space 71 along the second direction and are fixedly connected to two adjacent heat exchange plates 231 respectively.

[0040] In the above embodiments, multiple heat exchange plates 231 are fixedly connected to the same base plate 232, which facilitates the assembly and disassembly of the heat exchange assembly 23. In addition, the battery cell 221 is fixedly connected to two adjacent heat exchange plates 231 respectively, which enables the battery cell 221 to be more stably placed on the heat exchange plate 231, and the heat exchange plate 231 can provide more stable support for the battery cell 221.

[0041] In some specific embodiments, the battery cell 221 can be bonded to the heat exchange plate 231 with structural adhesive, and the battery cell 221 can also be bonded to the bottom surface of the first receiving space 70 with structural adhesive, which will not be described in detail here.

[0042] In some implementations, such as Figure 7 As shown, the heat exchange assembly 23 also includes an inlet pipe 233 and an outlet pipe 234. Each heat exchange plate 231 is connected to the inlet pipe 233 and the outlet pipe 234 respectively. The inlet pipe 233 is used to introduce heat exchange medium into the heat exchange plate 231 so that the heat exchange plate 231 can exchange heat with the battery cell 221. The outlet pipe 234 is used to let out the heat exchange medium after heat exchange in the heat exchange plate 231.

[0043] like Figure 7As shown, the liquid inlet pipe 233 includes a liquid inlet connector 233a, and a liquid inlet 50 is provided on the cockpit body 10. The liquid inlet connector 233a is connected to the liquid inlet 50, and the liquid inlet 50 can be connected to an external pipeline for introducing heat exchange medium into the heat exchange plate 231. The liquid outlet pipe 234 includes a liquid outlet connector 234a, and a liquid outlet 60 is provided on the cockpit body 10. The liquid outlet connector 234a is connected to the liquid outlet 60, and the liquid outlet 60 can be connected to an external pipeline for discharging the heat exchange medium that has undergone heat exchange in the heat exchange plate 231.

[0044] In some embodiments, the battery management module 28 and the high-voltage box 27 of the power battery 20 may also be disposed in the first receiving space 70 of the tray 211. For example... Figure 5 and Figure 6 As shown, when the heat exchange assembly 23 is disposed in the first receiving space 70 in the tray 211, the battery management module 28 and the high voltage box 27 are disposed on opposite sides of the heat exchange plate 231 on the substrate 232.

[0045] In the above embodiments, placing the battery management module 28 and the high-voltage box 27 in the first receiving space 70 of the tray 211 can further improve the integration of the battery system.

[0046] In some embodiments, the power battery 20 further includes an end plate 24. The cells 221 stacked in the accommodating space 71 along the second direction form a cell assembly 22. The end plate 24 is disposed at one end of the cell assembly 22 in the second direction and is used to clamp the cell assembly 22 between the end plate 24 and the side wall of the tray 211 or between the end plate 24 and the substrate 232, thereby providing a preload force to the cell assembly 22 to ensure that the cell assembly 22 can operate stably and safely.

[0047] In some embodiments, an end plate 24 is disposed between the heat exchange plate 231 and the substrate 232, for clamping the battery cell assembly 22 between the end plate 24 and the side wall of the tray 211. The end plate 24 is also provided with a first through hole 241 and a second through hole 242, wherein the first through hole 241 is for the passage of the inlet pipe 233 or the outlet pipe 234, and the second through hole 242 is for the passage of bolts. When the heat exchange plate 231 and the substrate 232 are connected by bolts, the bolts can pass through the second through hole 242 on the end plate 24 and be connected to the substrate 232; that is, both the heat exchange plate 231 and the end plate 24 can be fixedly connected to the substrate 232 by bolts. Furthermore, long bolts can be used to connect the end plate 24 to the bottom surface of the first receiving space 70 of the tray 211 to improve the ability of the end plate 24 to retain the preload force provided by the battery cell assembly 22.

[0048] In some embodiments, the cockpit body 10 includes a high-voltage connector 30 and a low-voltage communication connector 40. The high-voltage connector 30 can be connected via a wiring harness to transmit current from the power battery 20 to various components of the vehicle. The low-voltage communication connector 40 can be connected to the vehicle's controller via a wiring harness and can be used for communication between the power battery pack 20 and the vehicle's controller.

[0049] In some implementations, such as Figures 3 to 5 As shown, the battery cell 221 includes a safety valve 221a, which is positioned facing away from the bottom surface of the tray 211. The cockpit body 10 includes an occupant compartment 11 (driver's seat and front passenger seat). The power battery 20 can be arranged behind or below the occupant compartment 11, meaning the battery casing 21 of the power battery 20 can separate the occupant compartment 11 from the first accommodating space 70. The safety valves 221a of each battery cell 221 within the first accommodating space 70 are arranged facing away from the occupant compartment 11. This arrangement allows the battery cell 221 to depressurize and eject in a direction away from the cockpit in the event of thermal runaway, greatly improving the safety of the occupants in the cockpit.

[0050] In some implementations, such as Figure 3 As shown, an insulating film 25 is provided between the battery cell 221 and the top cover 212 to increase the creepage distance and improve electrical safety.

[0051] In some specific embodiments, the sidewall of the battery tray 211 is provided with a flange 211a, which adheres to the sidewall of the cockpit body 10 and can guide rainwater. The power battery 20 also includes a sealing ring 26, which adheres to the flange 211a. When the top cover 212 is fastened to the tray 211, the sealing ring can be used to seal between the top cover 212 and the tray 211. The top cover 212 can be made of sheet metal, and the surface of the top cover 212 can be stamped with a punch to improve structural strength. The top cover 212 is also provided with a pressure relief valve 212a, which can relieve pressure when the pressure in the first receiving space 70 of the power battery 20 increases, thereby improving the safety factor of the cockpit body 10.

[0052] A second aspect of this disclosure provides a vehicle including the cockpit assembly 100 provided in the first aspect of this disclosure. The vehicle includes, but is not limited to, a truck, and has all the beneficial effects of the aforementioned cockpit assembly 100, which will not be elaborated further here.
