Description

Technical Field

[0001] The present invention relates to the technical field of batteries, and in particular to a battery pack. Background Art

[0002] The high-voltage connector is the power transmission unit of the battery pack. The battery pack transmits power and electrical energy to the entire vehicle through the high-voltage connector. Therefore, the high-voltage connector is also the power transmission bridge between the internal battery pack and the external high-voltage equipment of the entire vehicle. In the related art, the high-voltage connector is connected to the top wall of the battery pack shell by bolts, so that the high-voltage connector is suspended in the housing cavity of the shell. The high-voltage connector is connected to the conductive member by bolts, and the conductive member is connected to the battery in the battery pack, thereby achieving an electrical connection between the high-voltage connector and the battery, so that the high-voltage connector can achieve power and electrical energy output. However, based on the design that the high-voltage connector relies on bolt connection with the top wall of the shell and bolt connection with the conductive member to achieve suspension support, the high-voltage connector is easily pulled by the weight of the conductive member itself, causing the bolts to loosen. If the bolts are loose, the high-voltage connector is easily pulled by the weight of the conductive member itself, causing it to shake or tilt, which will cause the connection between the high-voltage connector and the conductive member to loosen, affecting the stability of the electrical connection between the high-voltage connector and the battery.

[0029] The technical solutions in the embodiments of the present invention will be described below in conjunction with the accompanying drawings. The described embodiments are only configured to explain the concept of the present invention and should not be regarded as limiting the scope of protection of the present invention.

[0030] like Figure 1 as well as Figure 2 As shown, an embodiment of the present invention provides a battery pack 100, which includes a housing 10, a conductive member 20, a high-voltage connector 30, a battery ( Figure 1 Not shown) and a limiting frame 40.

[0031] The housing 10 is used to accommodate the conductive member 20, the high-voltage connector 30, the battery, and the retaining frame 40. The housing 10 includes an upper housing 11 and a lower housing 12. The upper housing 11 and the lower housing 12 interlock to form a receiving cavity for accommodating the conductive member 20, the high-voltage connector 30, the battery, and the retaining frame 40. The upper housing 11 and the lower housing 12 are fixedly connected by welding or bolting.

[0032] The lower shell 12 can be a hollow structure with one end open, and the upper shell 11 can be a plate-like structure. The upper shell 11 covers the open side of the lower shell 12, so that the upper shell 11 and the lower shell 12 jointly define a receiving cavity. The upper shell 11 and the lower shell 12 can also be hollow structures with one end open, and the open side of the upper shell 11 covers the open side of the lower shell 12. Of course, the housing 10 formed by the upper shell 11 and the lower shell 12 can have various shapes, such as a cylinder, a rectangular parallelepiped, etc.

[0033] The top wall of the housing 10 is provided with an opening 101, through which a portion of the high-voltage connector 30 is exposed outside the housing 10, allowing the high-voltage connector 30 to transmit power and electrical energy to an external electrical device. The top wall of the housing 10 is also provided with a fastening groove 102, into which a bolt 103 is assembled to securely connect the top wall of the housing 10 to the high-voltage connector 30.

[0034] The conductive member 20 is disposed in the housing 10. The conductive member 20 is connected to the high-voltage connector 30 so that the high-voltage connector 30 is suspended and supported in the housing 10. The conductive member 20 is used to realize the electrical connection between the high-voltage connector 30 and the battery. The conductive member 20 includes a total positive conductive bar 21, a total negative conductive bar 22, a sub-positive conductive bar 23, and a sub-negative conductive bar 24. The extension direction of the total positive conductive bar 21 is the same as the extension direction of the total negative conductive bar 22, the extension direction of the sub-positive conductive bar 23 and the sub-negative conductive bar 24 is the same, and the extension direction of the total positive conductive bar 21 intersects with the extension direction of the sub-positive conductive bar 23. For example, the extension direction of the total positive conductive bar 21 is the length direction of the housing 10, and the extension direction of the sub-positive conductive bar 23 is the width direction of the housing 10.

[0035] The conductive part 20 can be made of metal material copper or metal material aluminum. Copper and aluminum are both metal materials with good electrical conductivity. The conductivity of copper is better than that of aluminum, and the density of copper is greater than that of aluminum. However, the cost of making a copper conductive part is higher than the cost of making an aluminum conductive part.

[0036] One end of the main positive conductive bar 21 is connected to the positive terminal of the high-voltage connector 30, and the other end of the main positive conductive bar 21 is connected to the positive terminal of the battery. One end of the main negative conductive bar 22 is connected to the negative terminal of the high-voltage connector 30, and the other end of the main negative conductive bar 22 is connected to the negative terminal of the battery. One end of the sub-positive conductive bar 23 is connected to the positive terminal of the high-voltage connector 30, and the other end of the sub-positive conductive bar 23 is connected to the negative terminal of the battery. One end of the sub-negative conductive bar 24 is connected to the negative terminal of the high-voltage connector 30, and the other end of the sub-negative conductive bar 24 is connected to the negative terminal of the battery.

[0037] There may be multiple batteries, and these batteries may be connected in series, in parallel, or in a hybrid configuration. A hybrid configuration refers to a combination of series and parallel connections. Multiple batteries may be directly connected in series, in parallel, or in a hybrid configuration, and then the entire battery system is housed within the housing 10. Alternatively, the batteries in the battery pack 100 may be formed by first connecting multiple batteries in series, in parallel, or in a hybrid configuration to form a battery module, which is then further connected in series, in parallel, or in a hybrid configuration to form a single unit housed within the housing 10. The battery pack 100 may also include other configurations.

[0038] like Figure 1 、 Figure 2 as well as Figure 3 As shown, the high-voltage connector 30 further includes a base 31, and the conductive member 20 is disposed on a first surface 3101 of the base 31. The base 31 is insulated from the conductive member 20, so that the main positive conductive bar 21 and the sub-positive conductive bar 23 in the conductive member 20 are connected to the positive terminal of the high-voltage connector 30, and the main negative conductive bar 22 and the sub-negative conductive bar 24 in the conductive member 20 are connected to the negative terminal of the high-voltage connector 30. The first surface 3101 of the base 31 is opposite to the top wall of the housing 10, and the plane on which the first surface 3101 lies is parallel to the plane on which the top wall of the housing 10 lies. That is, the direction of the weight force exerted on the high-voltage connector 30 is perpendicular to the plane on which the first surface 3101 lies, and the direction of the weight force exerted on the conductive member 20 is perpendicular to the plane on which the first surface 3101 lies. The plane where the second surface 3102 of the base 31 is located is parallel to the plane where the top wall of the shell 10 is located, and the second surface 3102 of the base 31 is opposite to the first surface 3101 of the base 31, that is, the direction of the high-voltage connector 30's own gravity is perpendicular to the plane where the second surface 3102 is located, and the direction of the conductive part 20's own gravity is perpendicular to the plane where the second surface 3102 is located.

[0039] The limiting frame 40 is attached to the side wall of the shell 10 so that the limiting frame 40 is fixedly arranged on the side wall of the shell 10. The limiting frame 40 and the shell 10 can be fixedly connected by bolts, or by welding, and the welding process can adopt a resistance spot welding process. The resistance spot welding process can avoid the side wall of the shell 10 being welded when the limiting frame 40 and the side wall of the shell 10 are welded, thereby ensuring the airtightness of the shell 10 and reducing the possibility of external water vapor invading the interior of the battery pack 100 through the shell 10, so as to reduce the situation where the shell 10 is corroded by water vapor.

[0040] The limiting frame 40 is further connected to at least the second surface 3102 of the base 31 to support and limit the base 31. Based on the connection between the limiting frame 40 and the base 31 of the high-voltage connector 30, the limiting frame 40 supports the base 31, thereby limiting and supporting the base 31 of the high-voltage connector 30 along the direction of gravity of the high-voltage connector 30, that is, the direction of gravity of the conductive member 20.

[0041] Since the limit frame 40 limits the high-voltage connector 30 along the gravity direction of the conductive part 20, the limit frame 40 can limit the conductive part 20 from pulling the high-voltage connector 30 along the gravity direction it is subjected to, ensuring that the high-voltage connector 30 will not shake along the direction of the external force it is subjected to, that is, ensuring that the high-voltage connector 30 will not shake along the gravity direction of the conductive part 20 itself, thereby avoiding the connection between the high-voltage connector 30 and the conductive part 20 and the connection between the high-voltage connector 30 and the top wall of the shell 10 from loosening due to shaking, thereby ensuring the stability of the electrical connection between the high-voltage connector and the battery.

[0042] like Figures 3 to 5 As shown, the limiting frame 40 includes a support plate 41, which is provided with a limiting portion 411, which is nested with at least a portion of the base 31. The base 31 has a protrusion 311, and the limiting portion 411 is nested with the protrusion 311 of the base 31.

[0043] Similarly, in some other embodiments, the support plate 41 has a protrusion, the base 31 has a groove, and the protrusion of the support plate 41 is nested with the groove of the base 31.

[0044] The plane of the support plate 41 is parallel to the plane of the second surface of the base 31. The direction of gravity acting on the base 31 is perpendicular to the plane of the support plate 41. Therefore, the interaction force exerted on the support plate 41 by the base 31 is perpendicular to the plane of the support plate 41. Therefore, the support plate 41 supports and limits the base 31 of the high-voltage connector 30 along the direction of gravity of the high-voltage connector 30, that is, the direction of gravity of the conductive member 20, thereby preventing the high-voltage connector 30 from shaking along the direction of gravity of the conductive member 20.

[0045] The limiting portion 411 includes a first limiting sub-portion 4111, which is formed by a recessed side edge of the support plate 41, that is, the periphery of the first limiting sub-portion 4111 is not closed. The support plate 41 can have multiple first limiting sub-portions 4111, and the multiple first limiting sub-portions 4111 can be arranged on the same side edge of the support plate 41, or the multiple first limiting sub-portions 4111 can be arranged on different side edges of the support plate 41. The orthographic projection pattern of the first limiting sub-portion 4111 can be different shapes, such as a semicircle, a cone, a U-shape, or a U-shape. The orthographic projection pattern of the first limiting sub-portion 4111 can be a regular pattern or an irregular pattern.

[0046] The protrusion 311 includes a first protrusion 3111, which is nested with the first limiting sub-portion 4111 of the support plate 41. Because the first limiting sub-portion 4111 is formed by a recess in the side edge of the support plate 41, and the recess direction of the side edge of the support plate 41 is the first direction, the nesting of the first protrusion 3111 and the first limiting sub-portion 4111 can prevent the base 31 from rocking along a second direction on the plane of the support plate 41. The second direction intersects the first direction, and the plane formed by the intersection of the second direction and the first direction is parallel to the plane of the support plate 41. The width of the first protrusion 3111 is less than or equal to the width of the first limiting sub-portion 4111. When the width of the first protrusion 3111 is equal to the width of the first limiting sub-portion 4111, the side surface of the first protrusion 3111 abuts against the first limiting sub-portion 4111.

[0047] like Figure 5 As shown, the side edge of the support plate 41 includes a first sub-side edge a1 and a second sub-side edge a2, and the second sub-side edge a2 is recessed to form a first position-limiting sub-portion 4111. The first sub-side edge a1 and the second sub-side edge a2 are smoothly connected, that is, the portion where the first sub-side edge a1 and the second sub-side edge a2 connect is arc-shaped, so that the protrusion 311 can be smoothly nested in the first sub-position-limiting sub-portion 4111.

[0048] The limiting portion 411 also includes a second limiting sub-portion 4112, which is disposed on the support plate 41 and has a closed periphery, i.e., the second limiting sub-portion 4112 is hole-shaped. The support plate 41 can have multiple second limiting sub-portions 4112, and the number of second limiting sub-portions 4112 can be set according to actual needs. The orthographic projection pattern of the second limiting sub-portion 4112 can have different shapes, such as a closed circle or a closed polygon. The orthographic projection pattern of the second limiting sub-portion 4112 can be a regular pattern or an irregular pattern.

[0049] The protrusion 311 includes a second protrusion 3112, which nests with the second position-limiting sub-portion 4112 of the support plate 41. Because the second position-limiting sub-portion 4112 has a closed periphery, the nesting of the second protrusion 3112 and the second position-limiting sub-portion 4112 can restrict the base 31 from moving in any direction on the plane of the support plate 41. The diameter of the second protrusion 3112 is less than or equal to the diameter of the second position-limiting sub-portion 4112. When the diameter of the second protrusion 3112 is equal to the diameter of the second position-limiting sub-portion 4112, the side surface of the second protrusion 3112 abuts against the second position-limiting sub-portion 4112.

[0050] like Figures 1 to 6 As shown, the limiting frame 40 also includes a first connecting plate 43 and a second connecting plate 44. The first connecting plate 43 is attached to the side wall of the housing 10, and the second connecting plate 44 is connected to the first connecting plate 43. The second connecting plate is connected to the support plate 41. The first connecting plate 43 is attached to the side wall of the housing 10 to achieve a fixed connection between the first connecting plate 43 and the side wall of the housing 10. The second connecting plate 44 is connected to the first connecting plate 43 and the support plate 41 respectively. The second connecting plate 44 provides support for the support plate 41 and also facilitates adjustment of the angle of the plane on which the support plate 41 is located relative to the plane on which the top wall of the housing 10 is located.

[0051] like Figure 6 as well as Figure 7 As shown, the angle between the second connecting plate 44 and the plane on which the support plate 41 is located can be a right angle, so that the plane on which the support plate 41 is located is parallel to the plane on which the top wall of the housing 10 is located, so that the base 31 of the high-voltage connector 30 is placed on the limit frame 40 and will not wobble on the plane on which the support plate 41 is located due to the influence of the weight of the conductive member 20 itself. The right angle in this embodiment refers to an angle in the specific range of 85° to 95°. Specifically, the right angle can be 85°, 86°, 87°, 88°, 89°, 90°, 91°, 92°, 93°, 94°, or 95°.

[0052] The second connecting plate 44 and the first connecting plate 43 have a first angle, which is an obtuse angle. The specific range of the first angle is 100° to 165°. Specifically, the first angle can be 165°, 160°, 155°, 150°, 145°, 140°, 135°, 130°, 125°, 120°, 115°, 110°, 105°, or 100°. The obtuse first angle between the second connecting plate 44 and the first connecting plate 43 facilitates connecting the first connecting plate 43 to the side wall of the housing 10.

[0053] The limiting frame 40 further includes a reinforcing plate 42, which is connected to the support plate 41 and is further connected to the second connecting plate 44. The arrangement of the reinforcing plate 42 ensures that the connection between the second connecting plate 44 and the support plate 41 is not easily changed even under external force.

[0054] The support plate 41 includes a main support plate 4101 and a support extension plate 4102. The orthographic projection of the main support plate 4101 is within the orthographic projection of the base 31. Therefore, the main support plate 4101 is connected to the second connecting plate 44, ensuring the maximum effective connection area between the support plate 41 and the second connecting plate 44, which facilitates the stability of the connection between the second connecting plate 44 and the support plate 41. If the support plate 41 only includes the main support plate 4101, the main support plate 4101 will not contact or connect with the sidewalls of the housing 10, thereby affecting the stability of the support plate 41 in providing support and restraint for the base 31. Therefore, in this embodiment, the support plate 41 also includes a support extension plate 4102, which is connected to the main support plate 4101 and abuts against the sidewalls of the housing 10. The provision of the support extension plate 4102 enables the support plate 41 to abut against the sidewalls of the housing 10, further enhancing the stability of the support plate 41 in providing support and restraint for the base 31. The limiting portion 411 may be provided on the support main plate 4101 , the limiting portion 411 may also be provided on the support extension plate 4102 , or the limiting portion 411 may also be provided on both the support main plate 4101 and the support extension plate 4102 .

[0055] The support extension plate 4102 may be in a regular pattern or an irregular pattern. The support main body plate 4101 may be in a regular pattern or an irregular pattern.

[0056] like Figures 1 to 6 As shown, the support plate 41 also includes an extension connecting plate 4103, which is connected to the support extension plate 4102, and the extension connecting plate 4103 is attached to the side wall of the shell 10. Based on the setting of the extension connecting plate 4103, the support plate 41 is connected to the shell 10 through the extension connecting plate 4103, thereby further strengthening the stability of the support plate 41 in providing support and limitation to the base 31, so that the support plate 41 can support the base 31 while also being directly connected to the shell 10. The side edge of the support extension plate 4102 that abuts the side wall of the shell 10 is connected to the extension connecting plate 4103, so that the support main plate 4101, the support extension plate 4102 and the extension connecting plate 4103 are integrally formed. Figure 7 as well as Figure 8As shown, the support plate 41 includes a main support plate 4101 and a support extension plate 4102. The main support plate 4101 has a first side edge, a second side edge, a third side edge, and a fourth side edge. The first side edge of the main support plate 4101 is opposite to the second side edge, and the third side edge of the main support plate 4101 is opposite to the fourth side edge. The first side edge, third side edge, second side edge, and fourth side edge of the main support plate 4101 are sequentially connected to form the side edge of the main support plate 4101. The first side edge of the main support plate 4101 is connected to the support extension plate 4102, the second side edge of the main support plate 4101 is connected to the reinforcing plate 42, the third side edge of the main support plate 4101 is connected to the second connecting plate 44, and the fourth side edge of the main support plate 4101 is recessed to form a first limiting sub-portion 4111.

[0057] The first side edge of the second connecting plate 44 is connected to the third side edge of the support body plate 4101, the second side edge of the second connecting plate 44 is connected to the reinforcing plate 42, and the third side edge of the second connecting plate 44 is connected to the first connecting plate 43. The first side edge of the second connecting plate 44 is opposite to the third side edge of the second connecting plate 44, and the second side edge of the second connecting plate 44 is respectively connected to the first side edge of the second connecting plate 44 and the third side edge of the second connecting plate 44. The second side edge of the second connecting plate 44 is flush with the third side edge of the support body plate 4101, so that the second connecting plate 44 and the support body plate 4101 are integrally formed.

[0058] The first side edge of the first connecting plate 43 is connected to the third side edge of the second connecting plate 44, and the second side edge of the first connecting plate 43 is adjacent to the first side edge of the first connecting plate 43. The second side edge of the first connecting plate 43 is flush with the second side edge of the second connecting plate 44, so that the first connecting plate 43 and the second connecting plate 44 are integrally formed.

[0059] In some embodiments, the support plate 41, the first connecting plate 43, the second connecting plate 44 and the reinforcing plate 42 of the limit frame 40 are integrally formed. For example, the limit frame 40 is stamped out using sheet metal processing technology, which can reduce the processing time required to prepare the limit frame 40 and save production costs.

[0060] In some embodiments, as Figure 1 、 Figure 2 、 Figure 9As shown, to prevent a gap between the limit frame 40 and the base 31 of the high-voltage connector 30, a buffer layer 50 is provided in the battery pack 100, and the buffer layer 50 is disposed between the limit frame 40 and the base 31. The buffer layer 50 can reduce the impact of the base 31 on the limit frame 40 and prevent the limit frame 40 from vibrating. The buffer layer 50 can be made of a cushioning foam, or it can be made of a material such as rubber or sponge. The orthographic projection of the buffer layer 50 can only coincide with the orthographic projection of the support body plate 4101, ensuring that the buffer layer 50 is provided in the area where the orthographic projection of the base 31 overlaps with the orthographic projection of the support plate 41, thereby reducing the impact of the base 31 on the limit frame 40. The orthographic projection of the buffer layer 50 can also coincide with the orthographic projection of the support body plate 4101 and the support extension plate 4102, ensuring that the buffer layer is provided in the area corresponding to the surface of the support plate 41 supporting the base 31, thereby reducing the impact of the base 31 on the limit frame 40.

[0061] Of course, the present invention may have many other embodiments. Without departing from the spirit and essential points of the present invention, those skilled in the art may make various corresponding changes and modifications based on this application, but these corresponding changes and modifications should all fall within the scope of protection of the claims attached to the present invention.
