For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating the examples of the present application.

[0025] In order to solve the problems in the prior art, the embodiments of the present application provide a mounting structure, a battery box and a vehicle. The mounting structure provided by the embodiments of the present application is first introduced below.

[0026] Figure 1 is a cross-sectional view of a mounting structure provided in some embodiments of the present application, Figure 2 It is an exploded view of the mounting structure improved in some embodiments of the present application.

[0027] like Figure 1 and Figure 2 As shown, on the one hand, the present application provides a mounting structure, including a mounting member 100, a fixing member 102 and a first sealing member 104, the mounting member 100 is used to pass through the battery box 101 along a first direction X and mount the battery box 101 on the body of the vehicle; the fixing member 102 is used to fix the battery box 101 to the mounting member 100, the fixing member 102 is sleeved and abuts against the outer periphery of the mounting member 100, along the second direction Y, the mounting member 100 is attached to the wall surface of the fixing member 102 and / or the fixing member 102 is attached to the wall surface of the mounting member 100 to form a first sealing groove 103, the first sealing groove 103 is arranged around the circumference of the mounting member 100; the first sealing member 104 is filled in the first sealing groove 103; the first direction X and the second direction Y are arranged to intersect.

[0028] The first direction X is the direction of the gravity of the battery box 101, that is, the direction of the pressure converted from the gravity of the battery box 101 on the mounting structure, and the first direction X is also the extension direction of the mounting member 100; the second direction Y is arranged to intersect with the first direction X, and preferably the second direction Y can be perpendicular to the first direction X, the second direction Y can be the width direction or the height direction of the mounting member 100, and the second direction Y can also be the horizontal direction.

[0029] The mounting component 100 can be connected to the chassis of the vehicle body, or it can also be connected to other positions of the vehicle body, which is not specifically limited here; the connection between the mounting component 100 and the vehicle body can be achieved by fasteners such as bolts, or it can also be achieved by fixing methods such as welding, which is not specifically limited here; the connection between one end of the mounting component 100 and the battery box 101 can be a fixed connection achieved by welding or the like, or it can be a movable connection achieved by bolts or clamping, etc. The specific connection method can be flexibly selected in actual application and is not specifically limited here.

[0030] The fixing member 102 is connected to the battery box 101, specifically to one end of the battery box 101 close to the vehicle body. At this time, the fixing member 102 and the mounting member 100 are respectively connected to the opposite sides of the battery box 101, so that the battery box 101 can be completely locked on the mounting member 100, ensuring the stability of the mounting member 100 after mounting the battery box 101 on the vehicle body.

[0031] The mounting member 100 is used to pass through the battery box 101 along the first direction X and mount the battery box 101 on the body of the vehicle, that is, the mounting member 100 passes through the battery box 101 along the gravity direction of the battery box 101 and mounts the battery box 101 on the body. At this time, one end of the mounting member 100 can be connected to the lower side of the battery box 101, and the other end of the mounting member 100 can pass through the battery box 101 from the upper side of the battery box 101 and connect to the body of the vehicle, so as to mount the battery pack on the body; it can be understood that the mounting of the present application refers to the mounting member 100 hanging the battery box 101 on the body along the gravity direction of the battery box 101. At this time, the gravity of the battery box 101 is converted and The resulting pressure will be transmitted between the mounting member 100 and the fixing member 102 along the first direction X. The pressure on the end face of the mounting member 100 abutting against the fixing member 102 along the first direction X is much greater than that on the wall face of the mounting member 100 along the second direction Y, and is therefore more easily crushed. At this time, if a sealing groove is provided on the end face of the mounting member 100 abutting against the fixing member 102 along the first direction X, the structural strength of the end face will be reduced. When the battery pack is mounted on the vehicle body, the mounting member 100 is subjected to greater force at the end face and has lower strength, and is therefore very easily crushed, thereby affecting the mounting effect of the entire mounting structure on the battery box 101 and the sealing effect of the battery box 101.

[0032] Therefore, in the embodiment of the present application, a first sealing groove 103 is provided on the wall surface of the mounting member 100 that is in contact with the fixing member 102 and / or the wall surface of the fixing member 102 that is in contact with the mounting member 100, and the first sealing groove 103 is arranged around the circumference of the mounting member 100; the first sealing member 104 fills the first sealing groove 103, so that the sealing performance of the battery box 101 can be ensured by the first sealing member 104. At the same time, since the first sealing groove 103 is provided on the wall surface of the mounting member 100 and / or the fixing member 102 along the second direction Y, it is possible to avoid affecting the structural strength of the end face of the mounting member 100 that abuts against the fixing member 102 along the first direction X. When the mounting structure is subjected to the pressure converted from the gravity of the battery box 101, the possibility of the end face being crushed can be reduced, thereby ensuring the fixing effect of the mounting structure on the battery box 101.

[0033] Optionally, one end of the mounting component 100 can be connected to the bottom plate of the battery box 101, or to the bottom cross beam of the battery box 101, and the other end passes through the cover of the battery box 101 and extends to the outside of the battery box 101 to be connected to the vehicle body; the fixing component 102 can be connected to the cover of the battery box 101 to lock the battery box 101 on the mounting component 100.

[0034] Optionally, the first sealing member 104 may be a rubber sealing ring, a sealing colloid or other sealing structures.

[0035] Please continue to refer to Figure 1 and Figure 2 In some embodiments, the mounting component 100 includes a mounting body 105 and a first fastening element 106. The mounting body 105 is used to connect with the battery box 101. The fixing component 102 is sleeved on the outer periphery of the mounting body 105. The mounting body 105 has a through hole along the first direction X. One end of the first fastening element 106 abuts against the mounting body 105, and the other end passes through the through hole and is used to connect with the vehicle body.

[0036] The mounting body 105 can be configured as a sleeve-shaped structure, and the mounting body 105 extends from the lower side of the battery box 101 to the upper side of the battery box 101 along the first direction X, and the mounting body 105 is connected to the lower side of the battery box 101; the first fastening element 106 can be configured as a screw, a bolt or any other type of fastening element, and the first fastening element 106 extends along the first direction X. The first fastening element 106 is arranged in the through hole of the mounting body 105, one end of which abuts against one end of the mounting body 105 close to the lower side of the battery box 101, and the other end passes through the through hole and extends from the upper side of the battery box 101 to the outside, thereby connecting with the vehicle body through the first fastening element 106, and mounting the battery box 101 on the vehicle body.

[0037] In this embodiment, the mounting body 105 is connected to the battery box 101. At the same time, the first fastening element 106 passes through the through hole on the mounting body 105, so that one end thereof abuts against the mounting body 105, and the other end passes through the through hole and is connected to the vehicle body. When the battery box 101 is mounted on the vehicle body, the mounting component 100 can be easily disassembled and assembled. When one of the mounting body 105 or the first fastening element 106 is damaged, only the damaged component needs to be replaced without replacing the entire mounting component 100, thereby saving costs.

[0038] Please continue to refer to Figure 1 and Figure 2 In some embodiments, the mounting body 105 includes a first mounting section and a second mounting section arranged in sequence along a first direction X, the first fastening element 106 abuts against one end of the first mounting section away from the second mounting section, and the end of the first mounting section away from the second mounting section also protrudes along the second direction Y to form a step portion 107, the step portion 107 is used to abut against the battery box 101, and the fixing member 102 is sleeved on the outer periphery of the second mounting section and abuts against the second mounting section.

[0039] Since the first fastening element 106 abuts against one end of the first mounting section away from the second mounting section, and the first fastening element 106 passes through the upper side of the battery box 101 from the lower side of the battery box 101 and extends to the outside of the battery box 101, the first mounting section is arranged close to the lower side of the battery box 101 and the second mounting section is arranged close to the upper side of the battery box 101.

[0040] The first mounting section protrudes along the second direction Y to form a step portion 107, that is, the step portion 107 extends along the second direction Y; the step portion 107 abuts against the battery box 101, specifically, one end of the step portion 107 close to the second mounting section along the first direction X abuts against the side of the bottom plate of the battery box 101 away from the cover plate of the battery box 101, so that when the battery box 101 is mounted on the vehicle body along the first direction X, it can play a role in supporting the battery box 101.

[0041] It can be understood that since the step portion 107 is a solid structure with a certain structural strength, compared with connecting the first mounting section and the battery box 101 by welding or other connection methods, the step portion 107 can carry a battery box 101 with a heavier weight, thereby preventing the connection between the first mounting section and the battery box 101 from failing due to the excessive weight of the battery box 101, thereby affecting the mounting effect of the battery box 101; at the same time, by abutting the battery box 101 with the step portion 107, the difficulty of installation can be reduced and the installation efficiency can be improved.

[0042] Optionally, there may be multiple step portions 107 , which are spaced apart from each other along the periphery of the first mounting section; or, there may be one step portion 107 , which is surrounded by the periphery of the first mounting section.

[0043] In some embodiments, one end of the first mounting section close to the second mounting section is used to connect to the battery box 101 .

[0044] One end of the first mounting section close to the second mounting section is connected to the battery box 101, and can be specifically welded to the battery box 101 or connected by fastening parts such as bolts. Of course, the connection direction here is not limited to this and can be determined according to actual conditions; one end of the first mounting section close to the second connecting section can be connected to the bottom plate of the battery box 101, or it can also be connected to the crossbeam on the bottom plate of the battery box 101, which is not specifically limited here.

[0045] In this embodiment, the first mounting section is connected to the battery box 101 at one end close to the second mounting section, thereby cooperating with the step portion 107 on the first mounting section to further ensure the connection strength between the first mounting section and the battery box 101 and avoid failure of the connection between the two, thereby ensuring the mounting effect of the mounting component 100 on the battery box 101.

[0046] In some embodiments, an end of the step portion 107 away from the second mounting section is used to connect with the battery box 101 .

[0047] The end of the step portion 107 away from the second mounting section is used to connect with the battery box 101, and can be fixed to the battery box 101 by welding. Of course, it can also be fixed by bolts or colloids, which is not specifically limited here.

[0048] In this embodiment, the step portion 107 is connected to the battery box 101 at one end away from the second mounting section, and the step portion 107 is abutted against the battery box 101 at one end close to the second connection section. This can further improve the connection strength between the battery box 101 and the first mounting section, avoid connection failure, and ensure the mounting effect of the mounting component 100 on the battery box 101.

[0049] Please continue to refer to Figure 1 and Figure 2 In some embodiments, the fixing member 102 includes a transfer element 108 and a second fastening element 109. The transfer element 108 is sleeved on and abuts against the outer periphery of the mounting member 100. The outer periphery of the transfer element 108 protrudes along the second direction Y to form a boss 110. The second fastening element 109 is sleeved on the outer periphery of the transfer element 108 to lock the wall of the battery box 101 on the boss 110.

[0050] The adapter element 108 can be threadedly connected to the mounting part 100, and the adapter element 108 can be a sleeve-shaped structure, which is sleeved on the outer periphery of the mounting part 100; the second fastening element 109 is sleeved on the outer periphery of the adapter element 108, at this time, the second fastening element 109 is movably connected with the adapter element 108, that is, the adapter element 108 and the second fastening element 109 can be connected by threads, or the adapter element 108 and the second fastening element 109 can also be connected by bolts or other methods, which are not specifically limited here; the outer periphery of the adapter element 108 protrudes along the second direction Y to form a boss 110, and when the second fastening element 109 is sleeved on the outer periphery of the adapter element 108, the wall of the battery box 101 can be locked between the second fastening element 109 and the boss 110, and specifically, the cover of the battery box 101 can be locked by the second fastening element 109.

[0051] In this embodiment, an adapter element 108 is provided to be sleeved and abutted on the mounting member 100, and a second fastening element 109 is provided to be sleeved on the outer periphery of the adapter element 108, so that the wall of the battery box 101 can be locked between the boss 110 and the second fastener, so as to improve the connection strength between the battery box 101 and the mounting member 100, and ensure the stability of the mounting member 100 when the battery box 101 is mounted on the vehicle body. At the same time, the cover of the battery box 101 is locked by the cooperation of the second fastening element 109 and the adapter element 108. When the second fastening element 109 or the adapter element 108 is damaged, only the corresponding damaged parts need to be replaced, and there is no need to replace the fixing member 102 as a whole, thereby saving costs to a certain extent.

[0052] Please continue to refer to Figure 1 and Figure 2 In some embodiments, a second sealing groove is provided on one side of the adapter element 108 close to the second fastening element 109 along the first direction X, and the second sealing groove is arranged around the circumference of the mounting component 100; the mounting structure also includes a second sealing member 111, and the second sealing member 111 is filled in the second sealing groove.

[0053] It can be understood that since the cover of the battery box 101 is pressed between the adapter element 108 and the second fastening element 109, there is a certain gap between the cover and the adapter element 108, and outside air can leak into the battery box 101 through the gap, thereby affecting the sealing performance of the battery box 101.

[0054] Therefore, in this embodiment, a second sealing groove is arranged on one side of the adapter element 108 close to the second fastening element 109 along the first direction X, so that the second sealing groove is arranged around the circumference of the mounting component 100, and a second sealing member 111 is arranged to fill the second sealing groove. When the cover plate is pressed between the second fastener and the adapter element 108, the second sealing member 111 can effectively block external air from flowing into the battery box 101 through the gap between the cover plate and the adapter element 108, thereby ensuring the sealing performance of the battery box 101.

[0055] In some embodiments, in the first direction X, the boss 110 is configured to be tapered from one side close to the second fastening element 109 to the other side.

[0056] In this embodiment, when the battery box 101 is mounted on the vehicle body, the boss 110 of the adapter element 108 is gradually tapered from one side close to the second fastening element 109 to the other side along the second direction Y, thereby reducing the weight of the adapter element 108 to a certain extent, and then reducing the weight of the mounting structure, so as to reduce the load on the battery box 101 after it is mounted on the vehicle body.

[0057] Figure 3 This is an assembly diagram of the mounting structure provided in some embodiments of the present application assembled in a battery box.

[0058] On the other hand, the present application also provides a battery box 101, including a cover plate, a bottom plate and a mounting structure as described in any of the above items, the bottom plate and the cover plate are arranged relative to each other; one end of the mounting part 100 of the mounting structure is connected to the bottom plate, and the other end passes through the cover plate and is used to connect to the body of the vehicle, and the fixing part 102 of the mounting structure is connected to the cover plate.

[0059] On the other hand, the present application also provides a vehicle, including a vehicle body and the battery box 101 as described above, wherein a mounting part 100 of the battery box 101 is connected to the vehicle body.

[0060] The present application provides a mounting structure, a battery box 101 and a vehicle. The mounting structure includes a mounting member 100, a fixing member 102 and a first sealing member 104. The mounting member 100 is used to pass through the battery box 101 along a first direction X and mount the battery box 101 on the body of the vehicle. At the same time, the fixing member 102 is sleeved on the outer periphery of the mounting member 100 to achieve a further fixed connection between the battery box 101 and the mounting member 100. At this time, since the mounting member 100 is attached to the wall surface of the fixing member 102 and / or the fixing member 102 is attached to the wall surface of the mounting member 100, a first sealing groove 103 is formed. The first sealing groove 103 is arranged around the circumference of the mounting member 100, and the first sealing member 104 is provided. 4 is filled in the first sealing groove 103, so that the sealing performance of the battery box 101 can be ensured by the first sealing member 104, and because the first sealing groove 103 is formed on the wall surface of the mounting member 100 and / or the fixing member 102 along the second direction Y, the first direction X and the second direction Y are arranged crosswise, therefore, the arrangement of the first sealing groove 103 will not affect the structural strength of the end surface of the mounting member 100 abutting against the fixing member 102 along the first direction X, when the mounting structure is subjected to the pressure converted from the gravity of the battery box 101, the possibility of the end surface being crushed can be reduced, thereby ensuring the fixing effect of the mounting structure on the battery box 101 and the sealing effect of the battery box 101.

[0061] The above is only a specific implementation of the present application. Those skilled in the art can clearly understand that for the convenience and simplicity of description, the specific working processes of the systems, modules and units described above can refer to the corresponding processes in the aforementioned method embodiments, and will not be repeated here.
