[0014] In some embodiments, at least one of the first longitudinal mounting cavity and the second longitudinal mounting cavity is arranged perpendicular to the extension direction of the transverse mounting cavity. By arranging the longitudinal mounting cavity perpendicular to the extension direction of the transverse mounting cavity, the battery pack that needs to be vertically mounted can be adapted.

[0015] In some embodiments, the length and width of the first longitudinal mounting cavity and the second longitudinal mounting cavity are the same for accommodating the same size battery pack. By arranging the length and width of the first longitudinal mounting cavity and the second longitudinal mounting cavity to be the same size, two battery packs of the same size can be arranged in the housing part.

[0016] In some embodiments, the housing part as a whole is V-shaped in the range of the longitudinal mounting cavity region of the housing part; the first longitudinal mounting cavity and the second longitudinal mounting cavity are communicated to form a wiring cavity, so that the middle part of the housing part is formed with a hollow region, and the transverse mounting cavity, the first longitudinal mounting cavity, the wiring cavity, and the second longitudinal mounting cavity are sequentially arranged around the outer peripheral side of the hollow region.

[0039] The technical solutions in the present application will be described below with reference to the drawings.

[0040] In order to solve the problem of poor universality of the battery structure of the electric vehicle in the prior art, the present application provides a battery structure for a vehicle and a vehicle.

[0041] In some embodiments, as shown in Figures 1 to 4 The vehicle includes a battery structure, a body portion 80 and a wheel assembly 90. The wheel assembly 90 is at least two, the middle portion of the body portion 80 is provided with a mounting area for accommodating the battery structure, and at least one wheel assembly 90 is arranged at both ends of the body portion 80.

[0042] In some embodiments, the vehicle wheel assembly 90 is two, and the two vehicle wheel assemblies 90 are rotatably connected with the body part 80. It should be noted that the vehicle wheel assembly 90 in the figure is two, but it does not exclude that the vehicle wheel assembly 90 can be 3, 4, 5, or even more.

[0043] In some embodiments, as shown in Figures 1 to 4 The battery structure for the vehicle includes a housing part 10 and a battery pack 20. The housing part 10 includes at least a transverse mounting cavity 11, longitudinal mounting cavities including a first longitudinal mounting cavity 12 and a second longitudinal mounting cavity 13, which extend upward from the top of the transverse mounting cavity 11, respectively. At least two of the transverse mounting cavity 11, the first longitudinal mounting cavity 12 and the second longitudinal mounting cavity 13 are different in size and / or shape at least in part for accommodating battery packs 20 of different sizes and / or types and / or shapes. The battery structure of the utility model provides at least three mounting cavities, and the first longitudinal mounting cavity 12 and the second longitudinal mounting cavity 13 extend upward from the top of the transverse mounting cavity 11, respectively, which makes the combination degree between the multiple mounting cavities more free for accommodating battery packs 20 of different sizes and / or types and / or shapes. Through the rearrangement of the space in the housing part 10, the battery structure of the utility model has the characteristics of good versatility.

[0044] In some embodiments, three mounting cavities are provided in the housing part 10, and the number of mounting cavities can also be set to be more, such as 3, 4, 5, according to actual needs. When more mounting cavities are provided, the structure of the battery pack 20 is reasonably arranged, such as the size, number and arrangement of the mounting cavities.

[0045] In some embodiments, as shown in Figure 1 The housing part 10 includes at least two subparts 14, which are assembled together along the thickness direction of the housing part 10 to enclose the transverse mounting cavity 11, the first longitudinal mounting cavity 12 and the second longitudinal mounting cavity 13. The above arrangement facilitates the processing of the subparts 14, and the two subparts 14 are close to each other, which facilitates installation.

[0046] In some embodiments, in order to improve the structural strength and sealing performance of the housing part 10, each subpart 14 is integrally formed. The integrally formed subpart 14 avoids the influence of the battery pack 20 on the external environment humidity, i.e. damp, during use, ensuring the safety and reliability of the vehicle.

[0047] In some embodiments, the subpart 14 selects the number, arrangement and size of the mounting cavities according to the size and dimension of the battery pack 20 as needed before processing. Meanwhile, the way of setting multiple mounting cavities can also select different types of battery packs 20 to be pre-installed on a subpart 14 that is disassembled when the vehicle is returned to the factory for repair according to the development and improvement of the battery pack 20 to determine whether it can be matched, without disassembling the entire battery structure, avoiding unnecessary disassembly and installation. Meanwhile, the battery pack 20 can be installed on a subpart 14 first during installation, and after determining that the battery pack 20 is installed in place, the other subpart 14 is assembled along the thickness direction of the housing part 10 to the previous subpart 14.

[0048] In some embodiments, as shown in Figure 3 The battery structure also includes a limiting protrusion 30, which is arranged at the top of the first longitudinal mounting cavity 12 and / or the second longitudinal mounting cavity 13, and is used to limit the battery pack 20. By arranging the limiting protrusion 30 at the top of the battery pack 20 and abutting the top surface of the battery pack 20, the installation of the battery pack 20 is facilitated, and the battery pack 20 can be limited during use of the battery structure, avoiding movement of the battery pack 20 along the extension direction of the longitudinal mounting cavity.

[0049] In some embodiments, the limiting protrusion 30 is integrally formed with the subpart 14 to improve the connection strength between the limiting protrusion 30 and the subpart 14.

[0050] In some embodiments, the surface of the limiting protrusion 30 is provided with a flexible layer to avoid hard contact between the outer surface of the battery pack 20 and the limiting protrusion 30 during assembly and use of the battery pack 20.

[0051] In some embodiments, the limiting protrusion 30 is detachably connected with the subpart 14, and the position of the limiting protrusion 30 is selected according to the size and dimension of the battery pack 20, so as to limit different types and sizes of battery packs 20.

[0052] In some embodiments, the limiting protrusion 30 is threadedly connected with the subpart 14. For example, the limiting protrusion 30 is provided with a protrusion, the surface of the protrusion is provided with external threads, and the subpart 14 is provided with multiple internal threaded holes.

[0053] In some embodiments, the first longitudinal installation cavity 12 and the second longitudinal installation cavity 13 are communicated with the transverse installation cavity 11, the battery pack 20 can be accommodated in the transverse installation cavity 11, and / or in the first longitudinal installation cavity 12 and the transverse installation cavity 11, and / or in the second longitudinal installation cavity 13 and the transverse installation cavity 11. By setting the longitudinal installation cavity and the transverse installation cavity 11 to be communicated, the battery pack 20 can be placed in the transverse installation cavity 11 or in the longitudinal installation cavity and the transverse installation cavity 11 according to the size of the battery pack 20, so that the battery structure can be adapted to battery packs 20 of different sizes, improving the versatility of the battery structure. At the same time, the combination freedom of the installation cavity can be increased, thereby facilitating the placement of various types of battery packs 20 and the installation of other components.

[0054] In some embodiments, the housing part 10 can accommodate at least two types of battery packs 20. When the battery pack 20 is a lead-acid battery, the battery pack 20 is arranged in the transverse installation cavity 11. When the battery pack 20 is a lithium battery, the battery pack 20 is arranged in the first longitudinal installation cavity 12 and the transverse installation cavity 11, and / or in the second longitudinal installation cavity 13 and the transverse installation cavity 11. The lead-acid battery is large in size and heavy in weight, and arranging the lead-acid battery in the transverse installation cavity 11 can achieve uniform distribution of the weight of the battery structure.

[0055] In some embodiments, when the battery pack 20 is a lead-acid battery, the battery pack 20 is arranged in the transverse installation cavity, which can avoid the situation that the tilt arrangement of the lead-acid battery causes the battery structure to be biased to one side, which is not conducive to installation and disassembly.

[0056] In some embodiments, the first longitudinal installation cavity 12 and the second longitudinal installation cavity 13 have the same length and width for accommodating battery packs 20 of the same size. By setting the length and width of the first longitudinal installation cavity 12 and the second longitudinal installation cavity 13 to be the same size, two battery packs 20 of the same size can be arranged in the housing part 10.

[0057] In some embodiments, when the battery pack 20 is a lithium battery, the battery pack 20 includes a first battery pack 21 and a second battery pack 22, the first battery pack 21 is accommodated in the first longitudinal installation cavity 12 and the transverse installation cavity 11, and the second battery pack 22 is accommodated in the second longitudinal installation cavity 13 and the transverse installation cavity 11. The first longitudinal installation cavity 12 and the second longitudinal installation cavity 13 have the same length and width, but the length direction and the width direction are different, so as to optimize the overall structure and improve the user experience. When the first battery pack 21 and the second battery pack 22 are completely identical battery packs 20, the first battery pack 21 and the second battery pack 22 are similar to being arranged in parallel in the first longitudinal installation cavity 12 and the second longitudinal installation cavity 13.

[0058] Of course, the first battery pack 21 and the second battery pack 22 can also be different types of batteries. For example, different sizes, different materials, different types, etc. By providing different types of battery packs 20, the housing portion 10 can match the placement requirements of different battery packs 20. At the same time, in order to avoid mutual extrusion of multiple battery packs 20 arranged at the same time, different battery packs 20 can be placed in different mounting cavities. The communication design of multiple mounting cavities facilitates the installation and replacement of battery packs 20, as well as the connection between multiple battery packs 20, such as series connection and parallel connection.

[0059] In some embodiments, as shown in FIG. 1, the length direction of the first longitudinal mounting cavity 12 is parallel to the second direction Y, and the width direction of the first longitudinal mounting cavity 12 is parallel to the first direction X. The length direction of the second longitudinal mounting cavity 13 is parallel to the first direction X, and the width direction of the first longitudinal mounting cavity 12 is parallel to the second direction Y, i.e. the thickness of the first longitudinal mounting cavity 12 in the first direction X is less than the thickness of the second longitudinal mounting cavity 13, and the thickness of the first longitudinal mounting cavity 12 in the second direction Y is greater than the thickness of the second longitudinal mounting cavity 13. Figure 4 In some embodiments, the width W1 of the first longitudinal mounting cavity 12 and the width W2 of the second longitudinal mounting cavity 13 are the same, and the length L1 of the first longitudinal mounting cavity 12 and the length L2 of the second longitudinal mounting cavity 13 are the same.

[0060] In some embodiments, at least one of the first longitudinal mounting cavity 12 and the second longitudinal mounting cavity 13 is arranged perpendicular to the extension direction of the transverse mounting cavity 11. By arranging the longitudinal mounting cavity perpendicular to the extension direction of the transverse mounting cavity 11, the battery pack 20 that needs to be installed vertically can be adapted.

[0061] In some embodiments, the first longitudinal mounting cavity 12 and the second longitudinal mounting cavity 13 are arranged perpendicular to the extension direction of the transverse mounting cavity 11. By arranging the two mounting cavities perpendicular to the extension direction of the transverse mounting cavity 11, the battery pack 20 installed in the housing portion 10 and located in the first longitudinal mounting cavity 12 and the transverse mounting cavity 11 and the second longitudinal mounting cavity 13 and the transverse mounting cavity 11 is kept vertical, and the vertical direction of the battery pack 20 is limited by the cooperation of the bottom surface of the transverse mounting cavity 11 and the limiting protrusion 30.

[0062] In some embodiments, as shown in FIG. 1, the length direction of the first longitudinal mounting cavity 12 is parallel to the second direction Y, and the width direction of the first longitudinal mounting cavity 12 is parallel to the first direction X. The length direction of the second longitudinal mounting cavity 13 is parallel to the first direction X, and the width direction of the first longitudinal mounting cavity 12 is parallel to the second direction Y, i.e. the thickness of the first longitudinal mounting cavity 12 in the first direction X is less than the thickness of the second longitudinal mounting cavity 13, and the thickness of the first longitudinal mounting cavity 12 in the second direction Y is greater than the thickness of the second longitudinal mounting cavity 13.

[0063] Figure 3 ​As shown, the shell part 10 as a whole is V-shaped in the longitudinal installation cavity region of the shell part 10. The first longitudinal installation cavity 12 and the second longitudinal installation cavity 13 are communicated to form a wiring cavity 60, so that the middle part of the shell part 10 is formed with a hollow region 70, and the transverse installation cavity 11, the first longitudinal installation cavity 12, the wiring cavity 60, and the second longitudinal installation cavity 13 are sequentially arranged around the outer peripheral side of the hollow region 70. By arranging the longitudinal installation cavity region of the shell part 10 in a V shape, the appearance of the battery structure is improved, and the needs of users are met. The wiring cavity 60 can communicate two longitudinal installation cavities, and can ensure the connection between the two longitudinal installation cavities while avoiding the contact between the shell part 10 and the external environment. The hollow region 70 can increase the air flow path and improve the heat dissipation effect of the battery structure.

[0064] Meanwhile, the connecting wire passes through the wiring cavity 60 to connect the two battery packs 20, and the hollow region 70 formed facilitates the taking and placing of the sub part 14 in the production of the vehicle.

[0065] When the shell part 10 is arranged on the vehicle, the shell part 10 can simultaneously occupy the space in the front-rear direction of the vehicle and the space in the up-down direction of the vehicle, the space of the vehicle is reasonably utilized, and the appearance is more beautiful. The shell part 10 is in a V shape, which is more like a vehicle with a "V cylinder" engine, and can meet the love of users who pursue fashion.

[0066] It should be noted that since the battery pack 20 is mostly a common geometric structure, if the battery pack 20 is placed in the first longitudinal installation cavity 12 or the second longitudinal installation cavity 13, only a part of the space of the transverse installation cavity 11 is occupied. Meanwhile, in order to greatly improve the utilization rate of the internal space of the shell part 10, other battery accessories and components are placed in the remaining space in the transverse installation cavity 11, so that the structure inside the shell part 10 is more compact.

[0067] In some embodiments, when the shell part 10 is formed in a V shape, an included angle is formed between the side of the top of the shell part 10 and the extension direction of the transverse installation cavity 11, and the included angle is less than 90°. In some embodiments, the first longitudinal installation cavity 12 and the second longitudinal installation cavity 13 have an included angle between the extension directions thereof. The wiring cavity 60 is arranged at the top of the longitudinal installation cavity, so that a hollow region 70 with a cross section approximately like an inverted trapezoid is formed. The battery pack 20 generates heat during normal use, which is gradually transferred to the shell part 10. In the conventional battery structure without the hollow region 70, the air flow at the outer surface of the shell part 10 can take away the heat at the surface of the shell part 10 during the driving of the vehicle. The utility model further has a hollow region 70, and the air flow passes through the hollow region 70, further taking away the heat at the surfaces of the first longitudinal installation cavity 12 and the second longitudinal installation cavity 13, so that the heat dissipation effect is improved.

[0068] In some embodiments, as shown in FIG. 6,Figures 1 to 3 As shown, the shell part 10 further comprises a limiting support 40, which is accommodated in the shell part 10, and the two ends of the limiting support 40 are connected with the inner wall of the shell part 10. The part of the limiting support 40 between the two ends is raised to form a space for limiting the battery pack 20 between the inner wall of the shell part 10. The limiting support 40 is limited in the direction perpendicular to the longitudinal installation cavity by cooperating with the inner wall of the shell part 10, so that the battery pack 20 is limited in different directions, which ensures that the battery pack 20 is not easy to shake during actual use.

[0069] In some embodiments, the limiting support 40 is made of metal material, and the two ends of the limiting support 40 are provided with openings. During installation, the limiting support 40 is connected with the inner wall of the transverse installation cavity 11 by screws. When the battery pack 20 is a lithium battery and comprises a first battery pack 21 and a second battery pack 22, the limiting support 40 is two, and the two limiting supports 40 are respectively arranged corresponding to the first battery pack 21 and the second battery pack 22, and the limiting support 40 is located at the bottom of the battery pack 20. The limiting support 40 is provided with a hollow structure, so as to reduce the heat accumulation between the limiting support 40 and the battery pack 20.

[0070] In some embodiments, as shown, Figures 1 to 3 The first longitudinal installation cavity 12 and the transverse installation cavity 11 are communicated, and the second longitudinal installation cavity 13 and the transverse installation cavity 11 are communicated. The battery structure further comprises a controller 50, which is arranged in the first longitudinal installation cavity 12 and / or the second longitudinal installation cavity 13 when the battery pack 20 is arranged in the transverse installation cavity 11; and the controller 50 is arranged on the side of the limiting support 40 away from the battery pack 20 when the battery pack 20 is arranged in the first longitudinal installation cavity 12 and the transverse installation cavity 11, and / or arranged in the second longitudinal installation cavity 13 and the transverse installation cavity 11. By arranging the controller 50 on the limiting support 40 or in the installation cavity different from the battery pack 20, the internal space of the battery structure can be reasonably utilized.

[0071] In some embodiments, when the battery pack 20 is a lead-acid battery, it will occupy almost all the space of the transverse installation cavity. When the controller 50 is arranged in the first longitudinal installation cavity 12 or the second longitudinal installation cavity 13, it is located at the top end of the first longitudinal installation cavity 12 or the second longitudinal installation cavity 13. By arranging the controller 50 in a spaced manner from the battery pack 20, air is used for heat insulation, which effectively reduces the adverse effects of the heat generated by the battery pack 20 on the controller 50 for a long time.

[0072] In some embodiments, the battery structure further comprises a buffer structure, which is located between the limiting support 40 and the battery pack 20. By arranging the buffer structure, hard contact between the limiting support 40 and the outer peripheral surface of the battery pack 20 can be avoided, and wear of the battery pack 20 after long-term use can be avoided.

[0073] In some embodiments, the buffer structure is matched in size with the limiting support 40. When the vehicle encounters a bumpy road section, the vehicle shaking will cause the battery structure to shake. The limiting support 40 is affected by thermal expansion and contraction after long-term use, and a gap is easily formed between the limiting support 40 and the surface of the battery pack 20. The battery pack 20 is easily in hard contact with the limiting support 40. The buffer structure not only avoids hard contact between the battery pack 20 and the limiting support 40 when the battery structure shakes, but also plays a heat insulation role, avoiding heat transfer to the controller 50.

[0074] In some embodiments, when the shell part 10 is installed on the body part 80, the first longitudinal installation cavity 12 is arranged close to the front end of the body part 80 relative to the second longitudinal installation cavity 13, and the thickness of the shell part 10 at the second longitudinal installation cavity 13 is smaller than the thickness of the shell part 10 at the first longitudinal installation cavity 12 in the width direction of the body part 80. By setting the thickness of the second longitudinal installation cavity 13 at the rear end of the body part 80 to be smaller than the thickness of the first longitudinal installation cavity 12, the user's legs are not blocked by the second longitudinal installation cavity 13 when riding the vehicle, improving the user's experience.

[0075] In some embodiments, the width direction of the first longitudinal installation cavity 12 and the width direction of the second longitudinal installation cavity 13 are perpendicular, and the length direction of the first longitudinal installation cavity 12 and the length direction of the second longitudinal installation cavity 13 are perpendicular, ensuring that when the battery pack 20 is a lithium battery, the first battery pack 21 and the second battery pack 22 can be accommodated in the shell part 10 without reducing the user's riding experience.

The side of the housing part 10 close to the reinforcing beams 84 has at least one third connecting structure fixed to the reinforcing beams 84 or the third beam structure 83.

[0082] In some embodiments, the first connecting structure, the second connecting structure and the third connecting structure are two connecting arms, with a through hole formed on each connecting arm, and a clamping space between the two connecting arms. The first beam structure 81, the second beam structure 82 and the third beam structure 83 are arranged in the clamping space of the first connecting structure, the second connecting structure and the third connecting structure respectively, and the first beam structure 81, the second beam structure 82 and the third beam structure 83 are also provided with connecting holes correspondingly. A bolt is connected to a nut by passing through the through hole and the connecting hole, so as to realize the connection between the battery structure and the body part 80.

[0083] In some embodiments, the housing part 10 is hinged to the frame, so as to avoid the disconnection of the housing part 10 during the forward movement of the vehicle. In order to charge the vehicle, a charging socket can also be arranged on the housing part 10 or the frame. In some embodiments, as shown in Figures 1 to 2As shown, the vehicle further comprises a seat body 100, which is arranged on the third beam structure 83, wherein the lowest point of the seat body 100 is arranged higher than the top point of the shell body 10; and / or the downward projection of the seat body 100 can overlap with the rear end part area of the shell body 10; and / or the upward projection of the shell body 10 can overlap with the front end part area of the seat body 100. The seat body 100 is arranged on the frame and the projection of the seat body 100 is located at the rear end of the shell body 10, so that the user's legs are not interfered with by the shell body 10 when riding.

[0084] In some embodiments, the seat body 100 is arranged on the third beam structure 83 and detachably connected with the third beam structure 83, and the distance between the seat body 100 and the third beam structure 83 can be adjusted. A resilient member is arranged between the seat body 100 and the third beam structure 83 to further improve the user experience.

[0085] In some embodiments, the vehicle further comprises a seat body 100 and a cover 110. The seat body 100 is arranged on the third beam structure 83.
