Description

Technical Field

[0001] The present application relates to the field of energy storage technology, and in particular to a battery device, an electrical device and an output pole protection component. Background Art

[0002] Multiple battery cells are connected in series and parallel to form a battery cell group, and multiple battery cell groups are electrically connected through connecting sheets (generally copper sheets) to form a battery device. The battery cell group has an output pole, one end of which is connected to the electrode terminal of the battery cell, and the other end of which is connected to the connecting sheet to achieve electrical connection between multiple battery cell groups.

[0003] The output pole is usually an exposed copper sheet. During the transportation and use of the battery device, the output pole may come into contact with an external conductor, posing a risk of short circuit. For this reason, a protective cover is generally provided to cover the output pole. There are also high-voltage boxes or other components in the battery device, which are also connected to the battery cell group through connecting parts. There are also other supporting structures to fix these connecting parts, resulting in a large number of parts in the battery device, a messy layout, and increased device and material costs. Utility Model Content

[0004] In view of the above problems, the present application provides a battery device, an electrical equipment and an output pole protection assembly. By improving the structure of the output pole protection assembly, the output pole protection assembly can not only cover the output pole, but also support and fix other connecting components in the battery device, thereby reducing the number of parts in the box.

[0005] In a first aspect, the present application provides a battery device, the battery device comprising:

[0006] A box body, in which a battery cell group is arranged, and the battery cell group is stacked and arranged along a first direction;

[0007] An abutment member, which is arranged at one end of the battery cell group along the first direction and is used to abut against the battery cell group;

[0008] An output pole is electrically connected to the battery cell group, and a projection of the output pole at least partially falls on the abutment member along a second direction, and the second direction is perpendicular to the first direction;

[0009] The output pole protection assembly is arranged on the abutment, and comprises a cover body and a support body. The cover body is at least partially arranged on the side of the output pole away from the abutment, and the support body is arranged on the cover body and supports and connects the connecting component adjacent to the output pole.

[0010] By setting an output pole protection component, and setting the output pole protection component to include a cover body and a support body, the cover body protects the output pole to prevent the output pole from contacting with an external conductor, avoiding the risk of short circuit, and improving the safety of the battery device. At the same time, the support body can also support and connect the connecting parts adjacent to the output pole, without the need to set up additional brackets to support and connect other connecting parts, reducing the number of parts in the box, facilitating the reasonable layout of the parts in the box, and reducing the device cost and material base.

[0011] In some embodiments, the cover is connected to the abutment member via a first fastener; and / or

[0012] The supporting body is connected to the connecting component via a second fastener.

[0013] The cover body and the abutment member are connected by the first fastener to achieve a firm installation of the cover body. The support body and the connection member are connected by the second fastener to achieve a firm installation of the connection member.

[0014] In some embodiments, the first fastener and / or the second fastener is configured as a threaded connection.

[0015] The use of threaded connectors can further ensure the firmness of the connection between the cover body and other connecting components.

[0016] In some embodiments, the cover body is disposed on the output pole, at least one of the cover body and the abutment member is provided with a groove, and the output pole is at least partially confined in the groove.

[0017] By arranging a groove on the cover body or the abutment, when the cover body is connected to the abutment, the output limit is located in the groove, thereby realizing the covering and limiting of the output pole by the cover body.

[0018] In some embodiments, the support body is arranged on the side of the cover body away from the groove, so that the output pole and the high-voltage box copper busbar are respectively located on both sides of the cover body, and the output pole and the high-voltage box copper busbar are separated by the cover body to better ensure the insulation between the output pole and the high-voltage box copper busbar.

[0019] In some embodiments, the cover comprises:

[0020] A cover portion, wherein a groove is provided on the cover portion along the extension direction of the output pole, and the output limit is located in the groove;

[0022] The cover body is firmly connected to the abutment member through two connecting parts, and the covering part covers the output pole.

[0023] In some embodiments, in the depth direction of the groove, the thickness of the connecting portion is smaller than the thickness of the covering portion.

[0024] By setting the cover part to a larger thickness, sufficient space can be provided for the groove to provide good protection for the output pole. The connection part is set to a smaller thickness, which can ensure a firm connection with the abutment part, while saving materials and reducing weight.

[0025] In some embodiments, the connection portion and the cover portion are arranged at an angle, and at least one first reinforcing rib is arranged between the connection portion and the cover portion, and the first reinforcing rib connects the connection portion and the cover portion.

[0026] By providing the first reinforcing rib, the connection strength between the connecting portion and the covering portion is improved, which is beneficial to improving the overall structural strength of the output pole protection assembly.

[0027] In some embodiments, the support body is disposed on the side of the cover body away from the output pole. Since the cover body is relatively thick, the support body is disposed on the side of the cover body away from the output pole, which can ensure a large distance between the support body and the output pole, thereby ensuring a better isolation effect between the high-voltage box copper busbar and the output pole.

[0028] In some embodiments, the cover body and the support body are constructed as an integral structure, which can be integrally formed by injection molding, which is relatively quick to process and has good structural strength.

[0029] In some embodiments, the support body comprises:

[0030] A supporting main body part, which is connected to the cover body and is used to support and connect the connecting components;

[0031] At least one second reinforcing rib is provided, and the second reinforcing rib connects and supports the main body and the cover body.

[0032] The connecting copper busbar and the high-voltage box copper busbar are supported and connected by arranging a supporting main body, and the structural strength of the supporting main body is improved by arranging a second reinforcing rib to prevent the supporting main body from breaking when subjected to external force.

[0033] In some embodiments, when a plurality of second reinforcing ribs are provided, the plurality of second reinforcing ribs are circumferentially spaced around the connecting surface between the supporting body and the cover body.

[0034] The plurality of second reinforcing ribs jointly provide support to the support main body, thereby ensuring that the support main body has a higher structural strength.

[0035] In some embodiments, the abutment member is configured as an end plate or a cross beam disposed within the abutment member.

[0036] In a second aspect, the present application further provides an electrical device, comprising a battery device as provided in any of the above embodiments, wherein the battery device is used to provide electrical energy.

[0037] In a third aspect, the present application further provides an output pole protection component, which is applied to the battery device provided in the above embodiment, and the output pole protection component includes:

[0038] A cover body, wherein a groove is provided on the cover body, and the groove can accommodate a connecting component;

[0058] From the perspective of market development, batteries are increasingly being used. Batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power and solar power stations, but are also widely used in electric vehicles such as electric bicycles, electric motorcycles, and electric cars, as well as military equipment and aerospace. With the continuous expansion of battery application areas, the market demand is also constantly expanding.

[0059] The battery device includes a box body and a battery cell group arranged in the box body. The battery cell group is integrated with multiple battery cells and connected to an output pole. The electrical connection between the multiple battery cell groups is achieved by connecting the output poles of the multiple battery cell groups.

[0060] The inventors of this application noticed that the output pole is exposed to the outside of the battery cell group. During the transportation and use of the battery device, the output pole may come into contact with an external conductor, posing a risk of short circuit. For this reason, a protective cover is generally provided to cover the output pole to protect the output pole. However, the traditional output pole protection assembly has a relatively simple function, and only covers the output pole for protection. There are also high-voltage boxes or other components in the battery device, which are also connected to the battery cell group through connecting parts such as copper sheets and aluminum sheets. This requires additional support structures to fix these connecting parts, resulting in a large number of parts in the battery device and a messy layout, which also increases the device cost and material cost.

[0061] After research, the inventor of the present application discovered that the function of the output pole protection assembly can be expanded. By improving the structure of the output pole protection assembly, the output pole protection assembly can protect the output pole, and at the same time, the output pole protection assembly can fix the connecting parts of the high-voltage box or some other components, so as to save the brackets in the box, thereby reducing the number of parts in the box and solving the problem of chaotic layout of parts in the box.

[0062] Based on such a design concept, the inventor of the present application has designed a battery device, including a box, an abutment, an output pole and an output pole protection assembly. A battery cell group is arranged in the box, and the battery cell group is stacked and arranged along a first direction. The abutment is arranged at one end of the battery cell group along the first direction, and is used to abut the battery cell group. The output pole is electrically connected to the battery cell group, and along the second direction, the projection of the output pole at least partially falls on the abutment, and the second direction is perpendicular to the first direction. The output pole protection assembly is arranged on the abutment, and the output pole protection assembly includes a cover body and a support body. The cover body is at least partially arranged on the side of the output pole away from the abutment, and the support body is arranged on the cover body, and supports and connects the connecting parts adjacent to the battery cell group. By setting the output pole protection assembly to include a cover body and a support body, the cover body is used to protect the output pole, and the support body is used to support and connect other connecting parts, such as the copper sheet of the high-voltage box, etc., without the need to set up an additional bracket to support and connect other connecting parts, the number of parts in the box is reduced, which is conducive to the reasonable layout of the parts in the box, and reduces the cost of the device and the material basis.

[0063] The battery device provided in the embodiment of the present application can be used in, but not limited to, energy storage devices or electrical equipment, and energy storage devices include energy storage containers, energy storage cabinets, etc. Electrical equipment can be, but not limited to, mobile phones, tablets, laptops, electric toys, electric tools, battery cars, electric cars, ships, spacecraft, etc. Among them, electric toys can include fixed or mobile electric toys, such as game consoles, electric car toys, electric ship toys, and electric airplane toys, etc., and spacecraft can include airplanes, rockets, space shuttles, and spacecraft, etc.

For example, the battery device may be used for starting, navigating and operating power requirements of the vehicle during driving.

[0065] The structures of the battery device, electrical equipment and output pole protection assembly provided in the embodiments of the present application are described below in conjunction with the accompanying drawings.

[0072] See also Figure 3 and Figure 4 The present application provides a battery device 100, comprising a box 10, a battery cell group 20, a contact member 21, an output pole 22 and an output pole protection assembly 23. The box 10 is provided with a battery cell group 20, and the battery cell group 20 is stacked and arranged along a first direction. The contact member 21 is provided on the battery cell group 20 along the first direction (i.e. Figure 4 The output pole 22 is electrically connected to the battery cell group 20. Along the second direction, the projection of the output pole 22 at least partially falls on the abutment member 21. The second direction is perpendicular to the first direction. The output pole protection assembly 23 is arranged on the abutment member 21. The output pole protection assembly 23 includes a cover 231 and a support 232. The cover 231 is at least partially arranged on the side of the output pole 22 away from the abutment member 21. The support 232 is arranged on the cover 231 and supports and connects the connecting parts adjacent to the output pole 22.

[0073] The battery device 100 provided in the embodiment of the present application, by setting the output pole protection assembly 23 to include a cover 231 and a support 232, and by setting the cover 231 at least partially on the side of the output pole 22 away from the abutment 21, the cover 231 forms protection for the output pole 22, so as to prevent the output pole 22 from contacting with an external conductor, avoid the risk of short circuit, and improve the safety of the battery device 100. At the same time, the support 232 can also support and connect the connecting parts adjacent to the output pole 22, without the need to set up additional brackets to support and connect other connecting parts, reducing the number of parts in the box 10, facilitating the reasonable layout of the parts in the box 10, and reducing the device cost and material base.

[0074] Specifically, the abutment member 21 is configured as an end plate or a cross beam disposed in the box body 10 . The end plate or the cross beam is generally disposed at the end of the battery cell group 20 .

[0075] A high-voltage box 30 is disposed on the upper side of the battery cell group 20. The high-voltage box 30 has a high-voltage box copper bar 31. The output pole 22 adjacent to the battery cell group 20 is connected to the high-voltage box copper bar 31 through a connecting copper bar. The connecting copper bar and the high-voltage box copper bar 31 constitute the aforementioned connecting component, which can be supported and connected by a support body 232. Of course, the connecting component can also be other structures besides the connecting copper bar and the high-voltage box copper bar 31, which is not limited here.

[0076] In one embodiment, the cover 231 is connected to the abutment 21 by a first fastener; and / or the support 232 is connected to the connection member by a second fastener. The cover 231 and the abutment 21 are connected by the first fastener to achieve a secure installation of the cover 231. The support 232 and the connection member are connected by the second fastener to achieve a secure installation of the connection member.

[0077] Optionally, the first fastener and / or the second fastener is configured as a threaded connector, such as a bolt or a screw, etc. The threaded connector is used to further ensure the connection firmness between the cover 231 and other connecting components.

[0078] See also Figure 4 , Figure 4 A schematic diagram of the structure of the output pole protection assembly 23 provided in some embodiments of the present application. A second connection hole 23211 is provided on the support body 232, and the second fastener passes through the connection copper bar and the high-voltage box copper bar 31 and is threadedly connected to the second connection hole 23211, thereby achieving connection and fixation of the connection copper bar and the high-voltage box copper bar 31.

[0079] In some embodiments, Figure 3 As shown, the cover body 231 is covered on the output pole 22, and at least one of the cover body 231 and the abutment 21 is provided with a groove 23111, and the output pole 22 is at least partially limited in the groove 23111. Among them, the groove 23111 can be provided only on one of the cover body 231 or the abutment 21, and the output pole 22 is limited in the groove 23111. The grooves 23111 can also be relatively provided on the cover body 231 and the abutment 21, and the grooves 23111 on the cover body 231 and the grooves 23111 on the abutment 21 form a receiving cavity, and the output pole 22 is limited in the receiving cavity. Optionally, the shape of the groove 23111 independently provided on the cover body 231 matches the shape of the output pole 22 to achieve accurate positioning of the output pole 22. Similarly, the shape of the receiving cavity formed by the cover body 231 and the abutment 21 can also be set to match the shape of the output pole 22.

[0080] By providing a groove 23111 on the cover body 231 or on the abutment 21 , when the cover body 231 is connected to the abutment 21 , the output pole 22 is located in the groove 23111 , thereby achieving the covering and limiting of the output pole 22 by the cover body 231 .

[0081] In some implementations, the support body 232 is disposed on the side of the cover body 231 away from the groove 23111, so that the output pole 22 and the high-voltage box copper busbar 31 are respectively located on both sides of the cover body 231, and the output pole 22 and the high-voltage box copper busbar 31 are separated by the cover body 231 to better ensure the insulation between the output pole 22 and the high-voltage box copper busbar 31.

[0082] In some embodiments, in combination Figure 3 and Figure 4 As shown, the cover body 231 includes a cover portion 2311 and a connecting portion 2312. A groove 23111 is provided on the cover portion 2311 along the extending direction of the output pole 22, and the output pole 22 is limited in the groove 23111. Connecting portions 2312 are provided on both sides of the cover portion 2311 along the through direction of the groove 23111, and the connecting portions 2312 are connected to the abutment member 21. The extending direction of the output pole 22 refers to Figure 4 The arrangement direction of the two connecting parts 2312 refers to the direction of the arrow a shown in Figure 4 The cover 231 is firmly connected to the abutment member 21 through two connecting portions 2312 , and the covering portion 2311 covers the output pole 22 .

[0083] Further, the connecting portion 2312 is provided with a first connecting hole 23121, and the first fastener passes through the first connecting hole 23121 and is connected to the abutment 21. The first connecting hole 23121 can be specifically set as a threaded hole, and the first fastener is threadedly connected to the first connecting hole 23121 and the connecting hole on the abutment 21 to achieve a firm connection between the connecting portion 2312 and the abutment 21.

[0084] Of course, in some other embodiments, the cover 231 may be connected to the abutment 21 by snapping or bonding. The connection method between the cover 231 and the abutment 21 is not limited here, as long as the cover 231 can be firmly installed on the abutment 21.

[0085] Optionally, in the depth direction of the groove 23111, the thickness of the connecting portion 2312 is less than the thickness of the covering portion 2311. By setting the covering portion 2311 to be thicker, sufficient space can be provided for setting the groove 23111 to form a good protection for the output pole 22. The connecting portion 2312 is set to be thinner, that is, it can meet the requirements of a firm connection with the abutment 21, and at the same time play a role in saving materials and reducing weight.

[0086] Furthermore, the connection portion 2312 and the cover portion 2311 are arranged at an angle, and at least one first reinforcing rib 2313 is arranged between the connection portion 2312 and the cover portion 2311, and the first reinforcing rib 2313 connects the connection portion 2312 and the cover portion 2311. By providing the first reinforcing rib 2313, the connection strength between the connection portion 2312 and the cover portion 2311 is improved, which is beneficial to improving the overall structural strength of the output pole protection assembly 23.

[0087] Specifically, since the thickness of the connecting portion 2312 is less than the thickness of the cover portion 2311, a step is formed between the connecting portion 2312 and the cover portion 2311, and a 90-degree angle is naturally formed between the two. A first reinforcing rib 2313 is provided on each side of the connecting portion 2312, and the two first reinforcing ribs 2313 are arranged along direction a to further ensure the connection strength between the connecting portion 2312 and the cover portion 2311.

[0088] In one embodiment, the support body 232 is disposed on the side of the cover body 231 away from the output pole 22. Since the cover body 231 is relatively thick, the support body 232 is disposed on the side of the cover body 231 away from the output pole 22, which can ensure that a large distance is maintained between the support body 232 and the output pole 22, thereby ensuring a better isolation effect between the high-voltage box copper bar 31 and the output pole 22.

[0089] In one embodiment, the cover 231 and the support 232 are constructed as an integral structure. They can be integrally formed by injection molding, which is relatively fast to process and has good structural strength. Optionally, the cover 231 and the support 232 are made of plastic material to ensure good insulation and injection molding convenience.

[0090] In some embodiments, in combination Figure 3 and Figure 4 As shown, the support body 232 includes a support body 2321 and at least one second reinforcing rib 2322. The support body 2321 is connected to the cover 231 for supporting and connecting other connecting parts. The second reinforcing rib 2322 connects the support body 2321 and the cover 231. The support body 2321 is provided to support and connect the connecting copper bar and the high-voltage box copper bar 31, and the second reinforcing rib 2322 is provided to improve the structural strength of the support body 2321, so as to prevent the support body 2321 from breaking when subjected to external force.

[0091] Exemplarily, the supporting body portion 2321 is configured as a cylinder, and the aforementioned second connection hole 23211 is provided at the center of the upper end of the cylinder.

[0092] Optionally, the second reinforcing rib 2322 is extended along the height direction of the supporting main body portion 2321, wherein the second reinforcing rib 2322 is configured as a wedge-shaped structure, and the thickness of the second reinforcing rib 2322 gradually decreases from one end connected to the cover portion 2311 to the other end, so that the second reinforcing rib 2322 has a larger contact area with the cover portion 2311, thereby ensuring that the second reinforcing rib 2322 has higher supporting stability.

[0093] In some embodiments, when there are multiple second reinforcing ribs 2322, the multiple second reinforcing ribs 2322 are circumferentially spaced around the connecting surface between the support body 2321 and the cover body 231. The multiple second reinforcing ribs 2322 provide support to the support body 2321, ensuring that the support body 2321 has a higher structural strength.

The output pole protection assembly 23 is used to cover the part of the output pole 22 projected on the abutment 21 to prevent the external conductor from contacting the output pole 22 and causing a short circuit. At the same time, the output pole protection assembly 23 also plays a role in supporting and connecting other adjacent connecting components (such as the high-voltage box copper busbar 31 and the connecting copper busbar). Specifically, the output pole protection assembly 23 includes a cover body 231 and a support body 232. A groove 23111 is provided on the cover body 231. When the cover body covers the output pole 22, the output pole 22 is limited to the groove 23111. The support body 232 is disposed on the side of the cover body 231 away from the groove 23111, and the connection components adjacent to the battery cell group 20 are supported and connected by the support body 232. The battery cell group 20 proposed in the embodiment of the present application realizes the protection of the output pole 22 and the support connection of the high-voltage box copper bar 31 and the connection copper bar by setting the output pole protection component 23, without the need for additional brackets, reducing the number of parts in the box body 10, facilitating the reasonable layout of the parts in the box body 10, and reducing the device cost and material base.
