[0052] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention.

[0053] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present invention, its application, or uses.

[0054] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0055] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0056] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0057] The housing 10 of the starting power supply 1 according to the embodiment of the utility model is described in detail below with reference to the accompanying drawings.

[0058] like Figures 1 to 15 As shown, according to the shell 10 of the starting power supply 1 of the embodiment of the present application, in the first direction, one side of the shell 10 has a first surface 111 and a second surface 121, and the first surface 111 is higher than the second surface 121; in the second direction, the shell 10 includes a first part 11 and a second part 12, the first surface 111 is arranged on the first part 11, and the second surface 121 is arranged on the second part 12, the first part 11 is used to accommodate the battery cell module 21 and the battery management module 22, and the second surface 121 is used to install the terminal 3 electrically connected to the battery management module 22, and the first direction and the second direction have an angle.

[0059] In other words, the shell 10 of the starting power supply 1 according to the embodiment of the present application can be divided into a first part 11 and a second part 12 in the second direction, wherein the shell 10 can be an integral part or a split part, which is not limited here. For example, the shell 10 can be divided into a first part 11 and a second part 12 along a virtual plane in the second direction. Among them, the battery system 2 includes a battery cell module 21 and a battery management module 22, that is, there is a space inside the first part 11, which can accommodate the battery system 2. For example, the battery cell module 21 and the battery management module 22 are sequentially accommodated in the first part 11 along the vertical direction, and the battery management module 22 is located above the battery cell module 21. The second part 12 can be installed with a terminal 3, and the terminal 3 can be a positive terminal 31 or a negative terminal 32, and the terminal 3 is electrically connected to the battery management module 22. Among them, the battery management module 22 can be connected to the terminal 3 through a wiring harness.

[0060] In the first direction, the outer surface of one side of the housing 10 includes a first surface 111 and a second surface 121. For example, the first direction is an up-down direction, and the upper surface of the housing 10 includes a first surface 111 and a second surface 121. The first surface 111 is provided at the first portion 11, and the second surface 121 is provided at the second portion 12. There is a height difference between the first surface 111 and the second surface 121, and the first surface 111 is higher than the second surface 121, that is, in the first direction, the first surface 111 and the second surface 121 are staggered, and the first surface 111 is located at the front side of the second surface 121. It can be understood that the height here refers to the farthest position in the first direction, and the height difference between the first surface 111 and the second surface 121 refers to the difference in position between the first surface 111 and the second surface 121 in the first direction. It can be seen that, by forming a staggered design in the first direction between the first surface 111 and the second surface 121, a stepped portion structure can be formed between the first surface 111 and the second surface 121, and the higher area on the step portion corresponds to the first surface 111, and the lower area corresponds to the second surface 121. In other words, a stepped structure is formed on one side of the housing 10, and the installation height of the terminal 3 is relatively low.

[0061] Moreover, in the second direction, the housing 10 includes a first portion 11 and a second portion 12, that is, in the second direction, the second portion 12 is located outside the first portion 11. For example, the second direction is the left-right direction, and the second portion 12 is located on the right side of the first portion 11, which can avoid the second portion 12 being used to accommodate the space of the battery system 2, thereby ensuring the capacity of the battery module 21 and facilitating the setting of the battery management module 22. Since the second portion 12 is used to install the terminal 3, and since the second surface 121 is lower than the first surface 111, the installation area of ​​the terminal 3 can be lowered, which can reduce the space occupied by the terminal 3 in the first direction, avoid the terminal 3 from interfering with the surrounding parts, reduce the total volume of the housing 10, and thus reduce the space occupied by the starting power supply 1. Moreover, by arranging the terminal 3 outside the battery system 2, it can be avoided that the terminal 3 occupies the setting space of the battery system 2.

[0062] It should be noted that the first direction and the second direction have an angle, for example, the angle between the first direction and the second direction is 60°, 70°, 80°, 90° or 100°, etc. For ease of explanation, when the angle between the first direction and the second direction is 90°, the first direction can be defined as the Z-axis direction, and the second direction can be defined as the X-axis direction. In this embodiment, by adopting the first direction and the second direction having an angle between the extension directions, that is, the first direction and the second direction are arranged non-parallel, it is possible to achieve the limitation of the size and shape of at least two-dimensional space on the housing 10.

[0063] Therefore, according to the shell 10 of the starting power supply 1 according to the embodiment of the present application, by setting a step portion on the surface of the shell 10, not only the installation height of the terminal 3 is reduced, but also the space occupied by the shell 10 is reduced, and the installation space of the battery system 2 is avoided from being affected by the setting of the terminal 3.

[0064] In some specific embodiments of the present application, the housing 10 of the starting power supply 1 includes: an outer shell 13 and a cover 14. Specifically, a receiving space 15 having a first opening 131 is defined in the outer shell 13, at least a portion of the cover 14 is disposed at the first opening 131, the receiving space 15 is used to receive the battery cell module 21 and the battery management module 22, and a portion of the outer shell 13 or a portion of the cover 14 serves as the second portion 12.

[0065] That is to say, in this embodiment, the shell 10 of the starting power supply 1 is mainly composed of a shell 13 and a cover 14, and the shell 13 has a first opening, and the first opening 131 can be closed by at least a part of the cover 14. The shell 13 and the cover 14 cooperate to form a receiving space 15, and the receiving space 15 can be used to receive the battery system 2, specifically, the battery cell module 21 and the battery management module 22, that is, the receiving space 15 can play a role of accommodation. In addition, a part of the shell 13 or a part of the cover 14 is used as the second part 12, that is, in this embodiment, the terminal 3 can be provided on the shell 13 or on the cover 14, which is not limited here. It can be understood that in this embodiment, the terminal 3 can be provided on the shell 13 or on the cover 14, which is not limited here. For example, the shell 13 itself has a step portion, and the higher area of ​​the step portion has at least a part of the receiving space 15, and the lower area of ​​the step portion is provided with the terminal 3.

[0066] According to one embodiment of the present application, the receiving space 15 includes a first receiving cavity 151 and a second receiving cavity 152 arranged in sequence along a first direction, the first opening 131 is connected to the second receiving cavity 152, and the first surface 111 corresponds to the second receiving cavity 152, that is, the first surface 111 and the inner wall surface of the shell 13 can enclose and form the second receiving cavity 152. The first receiving cavity 151 is used to receive the battery cell module 21, and the second receiving cavity 152 is used to receive the battery management module 22. For example, the first direction is a vertical direction, and the receiving space 15 includes the first receiving cavity 151 and the second receiving cavity 152, wherein the second receiving cavity 152 is located above the first receiving cavity 151, that is, the battery management module 22 is located above the battery cell module 21, the first opening 131 is provided at the upper end of the shell 13, and the cover body 14 is located above the shell 13.

[0067] In this embodiment, by limiting the positional relationship between the first accommodating cavity 151 and the second accommodating cavity 152 in the first direction, not only can the spatial positional relationship between the battery cell module 21 and the battery management module 22 be limited, but also the first surface 111 corresponds to the second accommodating cavity 152, and the terminal 3 can be closer to the battery management module 22, thereby reducing the total length of the connecting line 4 between the terminal 3 and the battery management module 22.

[0068] In some specific embodiments of the present application, along the second direction, the cover body 14 includes a first cover portion 141 and a second cover portion 142, the first cover portion 141 is installed in the first opening 131 and has a first surface 111, the second cover portion 142 has a second surface 121, and the second cover portion 142 can be used to install the terminal 3; that is, along the first direction, at least a portion of the second cover portion 142 is lower than the first cover portion 141. In addition, along the second direction, the second cover portion 142 can be located at the outside of the first accommodating cavity 151 and the second accommodating cavity 152 at the same time.

[0069] That is, in this embodiment, the cover 14 is mainly composed of a first cover portion 141 and a second cover portion 142. The first cover portion 141 is installed on the first opening 131, and the first opening 131 can be closed by the first cover portion 141. The second cover portion 142 can be used to provide an installation area for the terminal 3. In this case, the second cover portion 142 can serve as the second portion 12. In this embodiment, the cover 14 has the functions of closing the first opening 131 and providing an installation area for the terminal 3, which simplifies the structure of the housing 10 and improves the integration of the cover 14.

[0070] According to one embodiment of the present application, the housing 13 further has a second opening 132, the second cover 142 is disposed at the second opening 132, a third accommodating chamber 153 is disposed between the housing 13 and the second cover 142, and the second opening 132 is connected to the third accommodating chamber 153. For example, the first accommodating chamber 151 and the second accommodating chamber 152 are enclosed between the left portion of the housing 13 and the first cover 141, and the third accommodating chamber 153 is enclosed between the right portion of the housing 13 and the second cover 142. In the vertical direction, the second accommodating chamber 152 is located above the first accommodating chamber 151, and the third accommodating chamber 153 is located on the right side of the first accommodating chamber 151 and the second accommodating chamber 152. Among them, the third accommodating chamber 153 can be used to accommodate the wiring harness connecting the terminal 3 and the battery management module 22. The upper end of the housing 13 has a first opening 131 and a second opening 132, respectively. The second opening 132 is disposed on the right side of the first opening 131. The second cover 142 is disposed at the second opening 132. The second cover 142 and the housing 13 cooperate to form a third accommodating cavity 153, which can accommodate at least a portion of the connection line 4 for connecting the terminal 3 and the battery management module 22. In this embodiment, the second cover 142 can be used to provide an installation area for the terminal 3 and can also be used to cooperate to form the third accommodating cavity 153, which has the effect of improving the integration of the cover 14.

[0071] In some specific embodiments of the present application, the housing 10 of the starting power supply 1 further includes: a mounting plate 23, which is disposed in the receiving space 15 and is used to separate the receiving space 15 into a plurality of receiving chambers. That is, a mounting plate 23 is also installed in the housing 13, and the receiving space 15 can be separated by the mounting plate 23, for example, the receiving space 15 is separated into a first receiving chamber 151 and a second receiving chamber 152, or the receiving space 15 is separated into a first receiving chamber 151 and a third receiving chamber 153, or the receiving space is separated into a first receiving chamber 151, a second receiving chamber 152 and a third receiving chamber 153 at the same time. In this embodiment, the receiving space 15 can be separated into a plurality of receiving chambers by using the mounting plate 23, which is convenient for installation and use. In addition, the mounting plate 23 can also be used to install the battery management module 22, etc., and can provide an installation area for the battery management module 22.

[0072] For example, the mounting plate 23 includes a first plate body 231 and a second plate body 232. The mounting plate 23 can be an integral part or a split part, which is not limited here. The first plate body 231 extends along the second direction, and the second plate body 232 extends along the first direction. The first plate body 231 can be divided into a first accommodating cavity 151 and a second accommodating cavity 152 in the first direction, and the second plate body 232 can be divided into the first accommodating cavity 151 and the third accommodating cavity 153 in the second direction. In addition, the second plate body 232 is prevented from occupying the space in the first direction, and the height of the terminal 3 will not be increased.

[0073] Optionally, the shape of the mounting plate 23 is L-shaped or Z-shaped, for example, the mounting plate 23 is L-shaped, and the first plate 231 and the second plate 232 can be combined to form an L-shaped structure; for another example, the shape of the mounting plate 23 is Z-shaped, and the edge of the first plate 231 or the second plate 232 can be bent, etc., which is conducive to the connection between the mounting plate 23 and the housing 13. In this embodiment, the shape of the mounting plate 23 is L-shaped or Z-shaped, etc., which has the advantages of structural diversity, flexible setting, and the ability to simultaneously limit the degrees of freedom in two directions, and also has the advantage of simple assembly. In addition, by adopting the shape of the mounting plate 23 to be L-shaped or Z-shaped, it is conducive to achieving a height difference on the surface of the housing 13, and the terminal 3 is arranged on the outside of the second direction of the battery system 2.

[0074] Optionally, one end of the first plate 231 in the second direction is connected to the second wall 134, and one end of the second plate 232 in the first direction is connected to the first wall 133. The connection here may include a detachable bolt and nut connection, welding, connection through a connecting column, etc., direct connection or indirect connection, which is not limited here. For example, one end of the first plate 231 is connected to the first connecting column 161 on the outer shell 13 through a connecting groove, and the first connecting column 161 on the outer shell 13 can extend along the second direction, so that pressure in the first direction can be generated on the first plate 231, and then the first plate 231 generates pressure in the first direction on the battery module 21. In this embodiment, by connecting the end of the first plate 231 to the second wall 134 and the end of the second plate 232 to the first wall 133, it is helpful to simplify the connection method between the mounting plate 23 and the outer shell 13, and simplify the structure inside the outer shell 13, leaving enough space for the battery module 21.

[0075] Optionally, a fixing plate 163 is further provided in the housing 13. The fixing plate 163 is L-shaped and can be located on a side of the second plate body 232 close to the battery module 21.

For example, the second connecting column 162 extends in the up-down direction, the fixing plate 163 is L-shaped, and the mounting plate 23 is Z-shaped. By adopting the fixing plate 163, the mounting plate 23 can be limited in the second direction, which is conducive to the fixation of the battery module 21.

For example, the battery 211 is a cylindrical battery 211, the axial direction of the battery 211 is the third direction, and the terminal 2111 is provided at the axial end of the battery 211.

[0077] According to one embodiment of the present application, the housing 10 of the starting power supply 1 further includes: a limiting plate 24, the limiting plate 24 is arranged in the first part 11, the limiting plate 24 has a mounting groove 241 that penetrates along the thickness direction of itself, and at least a part of the battery cell 211 of the battery cell module 21 is installed in the mounting groove 241. That is to say, a limiting plate 24 is also installed in the housing 13 of the starting power supply 1, for example, the limiting plate 24 can be installed in the first accommodating cavity 151. In addition, the limiting plate 24 can limit the battery cell 211. Optionally, one end of the terminal 2111 provided on the battery cell 211 is inserted into the mounting groove 241 along the axial direction of the mounting groove 241. In this embodiment, by adopting the limiting plate 24 and providing the mounting groove 241 on the limiting plate 24, the battery cell 211 can be limited to prevent the battery cell 211 from shifting.

[0078] In some specific embodiments of the present application, there are multiple battery cells 211, and the limiting plate 24 is provided with multiple mounting grooves 241, each mounting groove 241 corresponds to a battery cell 211.
