[0044] The following is a detailed description of the technical content, structural features, achieved objectives, and effects of the present invention. The following will be described in detail in conjunction with the embodiments and with reference to the accompanying drawings.

[0045] Refer to Figure 1 , according to the first embodiment of the present application, a vehicle body structure 1 is provided, including a top side longitudinal beam 10. The top side longitudinal beam 10 is provided with a battery accommodation cavity 40 for accommodating a battery pack. The top side longitudinal beam in the prior art does not have a structure for installing a battery pack. Compared with the vehicle body structure 1 of the present utility model, the structure is thin. The top side longitudinal beam 10 of the present utility model includes 8 cavities shown in the figure. The structure of the cavity is beneficial to reducing the weight of the vehicle and facilitating the lightweight of the vehicle. The present utility model adds a structure for installing a battery pack, and the battery pack has its own stiffness. By providing the battery accommodation cavity to install the battery pack, the stiffness of the top side longitudinal beam can be improved by using the self-stiffness of the battery pack.

[0046] In some possible embodiments, the top edge longitudinal beam 10 includes a mounting assembly 20 for mounting the battery pack and / or the curtain. There are multiple mounting assemblies 20, some for mounting the battery pack and some for mounting the curtain. The top edge longitudinal beam 10 not only serves as a body structure member for supporting the vehicle structure, but also is used to mount other parts, that is, it has multiple uses.

[0047] In some possible embodiments, the mounting assembly 20 is a chute structure. A chute is a device for sliding an object along a specified path and has an internal shape suitable for the movement of the object. Chutes are usually made of smooth materials such as metal, plastic, or fiberglass and can be used in various mechanical and engineering applications. The material of the top edge longitudinal beam 10 of the present utility model can be aluminum or steel. The principle of the chute is based on scientific principles and the action of friction. When an object moves along the chute, friction occurs between the object and the chute. Friction is the force generated by the contact surface between two objects and can prevent relative movement between the objects. However, by reducing friction, the chute can provide a smooth surface for the object to move along the chute with lower resistance. In the chute structure of this utility model, the chute is in a straight line shape, and the cross-section of the chute is a T-shaped groove structure. By sliding the fixing member into the chute, the battery pack or the curtain is fixed.

[0048] Refer to Figure 2 , in some possible embodiments, the mounting assembly 20 includes a first mounting portion 21 and a second mounting portion 22, and the first mounting portion 21 and the second mounting portion 22 are provided on the same side of the top edge longitudinal beam 10. The battery pack 41 is mounted on the first mounting portion 21 and the second mounting portion 22. Through the mounting structures of the first mounting portion 21 and the second mounting portion 22, the battery pack 41 is mounted in the same direction, which is beneficial to the fixation of the battery pack 41 and can more firmly fix the battery pack 41.

[0049] In some possible embodiments, the first mounting portion 21 and the second mounting portion 22 are connected to the battery pack 41 by square head bolts. The present utility model uses square head bolts and nuts as the fixing structure. Square head bolts are suitable for T-shaped grooves, that is, suitable for the chute structure proposed by the present utility model. The function of the square head bolt is to provide a reliable connection point in the T-shaped groove for fixing and connecting other components, that is, for fixing and connecting the T-shaped groove and the battery pack 41.

[0050] In some possible embodiments, the mounting assembly 20 includes a third mounting portion 23, and the third mounting portion 23 is provided on the bottom surface of the top edge longitudinal beam 10. The third mounting portion 23 is set as a chute structure. The chute structure can be a T-shaped groove structure or can be designed as other slidable chute structures. Through the fixing member, it can be used to mount the curtain structure. The bottom surface of the top edge longitudinal beam 10 has flexible space. By setting it to mount the curtain structure, the space can be fully utilized.

[0051] Referring to Figure 3 , in some possible embodiments, the top edge longitudinal beam 10 includes a water guide groove 30, and the water guide groove 30 is arranged on the top surface of the top edge longitudinal beam 10. The water guide groove 30 is a groove structure, and this groove structure is closed on three sides and the top surface is in an unclosed state, that is, an opening shape, and the opening faces the top of the top edge longitudinal beam 10. The function of the opening shape is to collect rainwater or other fluids falling on the top or side of the vehicle and discharge them through the water guide groove 30. That is, the function of the water guide groove 30 is to discharge rainwater or other fluids falling on the top or side of the vehicle out of the vehicle through the water guide groove 30. The water guide groove 30 includes a front vehicle water guide groove 31 and a rear vehicle water guide groove 32. The front vehicle water guide groove 31 is arranged in the front vehicle direction, and the rear vehicle water guide groove is arranged in the rear vehicle direction. The front vehicle water guide groove 31 and the rear vehicle water guide groove 32 are connected through. Rainwater or other fluids falling on the top or side of the vehicle are discharged through the front vehicle water guide groove 31 and the rear vehicle water guide groove 32. If rainwater or other fluids falling on the top or side of the vehicle are always placed on the roof or the side of the roof, it will increase the body weight and at the same time there is a risk of corroding the body, which is not conducive to the daily maintenance and driving safety of the vehicle. The front vehicle water guide groove 31 and the rear vehicle water guide groove 32 of the present utility model can realize the drainage function, which is conducive to the daily maintenance and driving safety of the vehicle. The connection surface from the topmost point of the top edge longitudinal beam 10 to the water guide groove 30 is an arc surface, and the design of the arc surface is conducive to rainwater or other fluids falling on the top or side of the vehicle to slide into the water guide groove 30. After accumulating in the water guide groove 30, it can be discharged out of the vehicle through the front vehicle water guide groove 31 and the rear vehicle water guide groove 32.

[0052] Referring to Figure 4, in some possible embodiments, the battery accommodation cavity 40 is at least partially covered by the air duct plate 51. A battery pack 41 is installed inside the battery accommodation cavity 40. The battery pack 41 is disposed in the battery accommodation cavity 40, and the battery accommodation cavity 40 is disposed in the air duct 5. The air duct 5 runs through from the front of the vehicle to the rear of the vehicle. A cooling medium is distributed in the air duct 5. While dissipating heat from the entire vehicle, the cooling medium can also dissipate heat from the battery pack 41 at the same time. The battery pack 41 is installed on the top side longitudinal beam 10 of the vehicle, and the battery pack 41 is disposed in the air duct 5. The battery pack 41 can utilize the cooling medium in the air duct 5 to dissipate heat from itself, reducing the temperature of the battery pack 41 itself and increasing the safety of the battery pack 41. The cooling medium in the air duct can be gaseous. The cooling medium is released into the air duct 5 through the corresponding radiator. On the one hand, the cooling medium dissipates heat from the passenger space in the vehicle, and on the other hand, it can also dissipate heat from the battery pack 41 in the air duct 5. When the cooling medium dissipates heat from the passenger space in the vehicle, the passengers can adjust the air volume by adjusting the air vents to obtain the effect they need. When the passengers need a larger air volume, they can appropriately open a larger air vent to get more air output and obtain a more cooling experience; when the passengers need a smaller air volume, they can appropriately reduce the size of the air vent, so that the air output will decrease, and a relatively comfortable cooling experience can be obtained; when the passengers do not need cooling, they can close the air vent, that is, there is no air output. When the cooling medium dissipates heat from the battery pack 41 in the air duct 5, the battery pack 51 can be cooled as a whole through the flow of the cooling medium in the air duct. The cooling medium in the air duct can also be liquid. The cooling plate can be arranged around the battery pack 41, and the battery pack 41 can be cooled through the flow channels. The flow channel plate can be arranged on the top, bottom or other positions of the battery pack. There are flow channels distributed in the flow channel plate, and the flow channels are filled with the cooling medium. The cooling medium flows in the flow channels. As the cooling medium flows, the heat generated by the battery pack 41 can be taken away, realizing the heat dissipation of the battery pack 41, enabling the battery pack to operate under better working conditions, increasing the safety of the battery pack 41, and reducing the adverse effects of high temperature of the battery pack on the battery pack 41.

[0053] Refer to Figure 5According to a possible embodiment of the present application, a vehicle 100 is provided, including a vehicle body structure 1 and an air duct plate 51. The air duct plate 51 at least partially covers the battery pack accommodating cavity 40, and a battery pack 41 is installed inside the battery pack accommodating cavity 40. The battery pack 41 is arranged in the battery pack accommodating cavity 40, and the battery pack accommodating cavity 40 is arranged in the air duct 5. The air duct 5 runs from the front direction to the rear direction of the vehicle. A cooling medium is distributed in the air duct 5. The cooling medium can dissipate heat for the battery pack 41 while dissipating heat for the entire vehicle. The battery pack 41 is installed on the top side longitudinal beam 10 of the vehicle, and the battery pack 41 is arranged in the air duct 5. The battery pack 41 can use the cooling medium in the air duct 5 to dissipate heat for the battery pack 41 itself, thereby reducing the temperature of the battery pack 41 itself and increasing the safety of the battery pack 41.

[0054] In some possible embodiments, the air duct plate 51 is removable and at least partially covers the battery pack accommodating cavity 40. The air duct plate is configured to be removable, and the air duct plate can be opened or closed by the air duct lock 52. By opening and closing the air duct plate 51, the battery pack 41 can be inspected and repaired. When the battery pack 41 needs to be inspected and repaired, the air duct lock 52 can be opened, so that the battery pack 41 can appear in front of the maintenance personnel, and the maintenance personnel can repair and inspect the battery pack. Compared with the battery pack arranged on the top of the vehicle, the utility model makes it easier and more convenient to repair the battery. There is no need to climb to the roof of the vehicle, nor to disassemble a large number of parts to repair the battery pack.

[0055] In some possible embodiments, the top longitudinal beams 10 are distributed on both sides of the vehicle, and the battery pack can be provided as one or more. The battery pack can be reasonably configured according to the power demand of the vehicle.

[0056] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0057] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0058] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
