Description

Technical Field

[0001] This utility model relates to the field of electric two-wheeled vehicle technology, and in particular to a heat dissipation component, a battery, and an electric two-wheeled vehicle. Background Technology

[0002] The battery of an electric two-wheeler typically consists of a casing and a cell module. The cell module is housed within the casing and comprises multiple cells arranged side-by-side. In related technologies, to improve heat dissipation, the sides of the cells are typically attached to the sidewalls of the casing, or a heat-conducting plate is installed between the sides of the cells and the sidewalls of the casing to transfer heat generated by the cells to the casing and dissipate it. However, during use, it has been found that due to manufacturing and installation errors, misalignment can easily occur on the same side of the cells. This results in some cells not being able to adhere to the sidewalls of the casing or the heat-conducting plate, leading to poor heat dissipation. Furthermore, when the sidewalls of the casing are impacted, the cell module is more susceptible to damage due to excessive impact force. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a heat dissipation component, which not only improves the heat dissipation effect of the battery, but also prevents the battery cell module from being damaged by excessive impact force.

[0004] This invention also proposes a battery having the above-mentioned heat dissipation components.

[0005] This utility model also proposes an electric two-wheeled vehicle with the above-mentioned battery.

[0006] A heat dissipation assembly according to a first aspect of the present invention is used for a battery. The battery includes a housing and a cell module. The cell module is disposed in the housing and includes a plurality of cells arranged side by side. The heat dissipation assembly includes a mounting bracket and a plurality of thermally conductive elastic elements. The mounting bracket is used to be mounted in the housing and extends along the arrangement direction of the plurality of cells. The plurality of thermally conductive elastic elements are disposed on the mounting bracket and arranged along the extension direction of the mounting bracket. The thermally conductive elastic elements are respectively provided with a first abutment portion and a second abutment portion on both sides of the extension direction of the mounting bracket. The first abutment portion and the second abutment portion of the same thermally conductive elastic element bend downward or upward in a direction away from each other. The plurality of first abutment portions are respectively used to abut the side edges of the plurality of cells in the width direction. The plurality of second abutment portions are used to abut the inner sidewall of the housing.

[0007] The heat dissipation assembly according to the embodiments of the present invention has at least the following beneficial effects:

[0008] In this invention, two heat dissipation components can be installed inside the battery casing. The two heat dissipation components are located on opposite sides of the cell module. The first abutting parts of multiple thermally conductive elastic elements of the same heat dissipation component abut against the corresponding side edges of multiple cells in the width direction. The second abutting parts of multiple thermally conductive elastic elements abut against the corresponding inner side wall of the casing. The heat generated by the cell can be transferred to the side wall of the casing through multiple thermally conductive elastic elements, and then dissipated to the outside through the side wall of the casing. According to the heat dissipation assembly of this utility model embodiment, since multiple thermally conductive elastic elements are individually arranged and the thermally conductive elastic elements are elastic, and the first and second abutting portions of the thermally conductive elastic elements bend downward or upward in a direction away from each other, the thermally conductive elastic elements can individually generate large elastic deformation along the width direction of the battery cell. Therefore, even if the same side of multiple battery cells is misaligned, the first and second abutting portions of the thermally conductive elastic elements can still tightly abut against the side of the battery cell in the width direction and the inner side wall of the casing, respectively, resulting in better heat conduction and thus better heat dissipation of the battery. Moreover, the thermally conductive elastic elements can play an elastic buffering role, thus preventing the battery cell module from being damaged by excessive impact when the side wall of the casing is hit.

The two ends of the mounting rod are respectively provided with connecting plates. The connecting plates are attached to the top surface of the second plate and a first fastener is installed between them. The first fastener passes through the first oblong hole.

[0018] According to some embodiments of the present invention, the thermally conductive elastic element and the mounting rod are fixed relative to each other along the circumferential direction of the mounting rod.

[0019] According to some embodiments of the present invention, the mounting rod includes two rod units, with the ends of the two rod units close to each other being inserted into each other. When the two rod units are separated, the thermally conductive elastic element can be removed from the ends of the two rod units close to each other.

[0020] The battery according to a second aspect embodiment of the present invention includes the heat dissipation component described in the first aspect embodiment above.

[0021] The battery according to the embodiments of the present invention has at least the following beneficial effects:

[0022] By employing the heat dissipation assembly of the first aspect of this utility model, since multiple thermally conductive elastic elements are individually arranged and the thermally conductive elastic elements are elastic, and the first and second abutting portions of the thermally conductive elastic elements bend downward or upward in a direction away from each other, the thermally conductive elastic elements can individually generate large elastic deformation along the width direction of the battery cell. Therefore, even if the same side of multiple battery cells is misaligned, the first and second abutting portions of the thermally conductive elastic elements can still tightly abut against the side of the battery cell in the width direction and the inner side wall of the casing, respectively, resulting in better heat conduction and thus better heat dissipation of the battery. Moreover, the thermally conductive elastic elements can play an elastic buffering role, thereby preventing the battery cell module from being damaged by excessive impact when the side wall of the casing is hit.

[0023] The electric two-wheeled vehicle according to a third aspect of the present invention includes the battery described in the second aspect of the present invention.

[0024] The electric two-wheeled vehicle according to the embodiments of this utility model has at least the following beneficial effects:

[0025] By employing the battery described in the second aspect of this utility model, since multiple thermally conductive elastic elements are individually arranged and the thermally conductive elastic elements are elastic, and the first and second abutting portions of the thermally conductive elastic elements bend downward or upward in a direction away from each other, the thermally conductive elastic elements can individually generate large elastic deformation along the width direction of the battery cell. Therefore, even if the same side of multiple battery cells is misaligned, the first and second abutting portions of the thermally conductive elastic elements can still tightly abut against the side of the battery cell in the width direction and the inner side wall of the casing, respectively, resulting in better heat conduction and thus better heat dissipation of the battery.

[0040] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0041] The following is for reference. Figures 1 to 3 This invention describes a heat dissipation assembly, a battery, and an electric two-wheeler according to embodiments of the present invention.

[0042] like Figures 1 to 3 As shown, the heat dissipation assembly 10 according to the first aspect of the present invention is used for a battery. The battery includes a housing 20 and a cell module 30. The cell module 30 is disposed inside the housing 20 and includes a plurality of cells 300 arranged side by side. The heat dissipation assembly 10 includes a mounting bracket 100 and a plurality of thermally conductive elastic elements 200.

[0043] The mounting bracket 100 is used to install inside the housing 20 and extends along the arrangement direction of the multiple battery cells 300. Multiple thermally conductive elastic elements 200 are provided on the mounting bracket 100 and arranged along the extension direction of the mounting bracket 100. The thermally conductive elastic elements 200 are respectively provided with a first abutment portion 201 and a second abutment portion 202 on both sides of the extension direction of the mounting bracket 100. The first abutment portion 201 and the second abutment portion 202 of the same thermally conductive elastic element 200 bend downward or upward in a direction away from each other. The multiple first abutment portions 201 are respectively used to abut against the side of the multiple battery cells 300 in the width direction, and the multiple second abutment portions 202 are used to abut against the inner sidewall of the housing 20.

[0044] In this invention, two heat dissipation components 10 can be installed inside the battery housing 20. The two heat dissipation components 10 are located on opposite sides of the cell module 30. The first abutting portions 201 of multiple thermally conductive elastic elements 200 of the same heat dissipation component 10 abut against the corresponding side edges in the width direction of multiple cells 300, and the second abutting portions 202 of multiple thermally conductive elastic elements 200 abut against the corresponding inner sidewall of the housing 20. The heat generated by the cell 300 can be transferred to the sidewall of the housing 20 through the multiple thermally conductive elastic elements 200, and then dissipated to the outside through the sidewall of the housing 20.

[0045] According to the heat dissipation assembly 10 of this utility model embodiment, since multiple thermally conductive elastic elements 200 are individually arranged and the thermally conductive elastic elements 200 are elastic, and the first abutting portion 201 and the second abutting portion 202 of the thermally conductive elastic elements 200 bend and extend downward or upward in a direction away from each other, the thermally conductive elastic elements 200 can individually generate large elastic deformation along the width direction of the battery cell 300. Therefore, even if the same side of multiple battery cells 300 is misaligned, the first abutting portion 201 and the second abutting portion 202 of the thermally conductive elastic elements 200 can still tightly abut against the side of the battery cell 300 in the width direction and the inner side wall of the housing 20, respectively, resulting in better heat conduction and thus better heat dissipation of the battery. Moreover, the thermally conductive elastic elements 200 can play an elastic buffering role, so that when the side wall of the housing 20 is impacted, the battery cell module 30 can be prevented from being damaged by excessive impact force.

[0046] It should be noted that the thermally conductive elastic element 200 can be made of thermally conductive rubber, thermally conductive silicone or other suitable thermally conductive elastic materials.

[0047] refer to Figure 3 As shown, in some embodiments of this utility model, a slot 203 is provided on the outer side of the first abutment portion 201, and the slot 203 allows the side of the power cell 300 to be inserted in the width direction. The first abutment portion 201 can be inserted into the side of the power cell 300 in the width direction through the slot 203, thus making the contact between the power cell 300 and the thermally conductive elastic member 200 tighter, the contact area larger, and the thermal conductivity better, thereby improving the heat dissipation effect of the battery.

[0048] refer to Figure 3 As shown, in some embodiments of this utility model, the bottom end of the slot 203 is through-hole. This arrangement makes it easier for the side of the battery cell 300 in the width direction to be inserted into the slot 203.

[0049] refer to Figure 2As shown, in some embodiments of this utility model, the mounting bracket 100 includes two mounting seats 101 and a mounting rod 102. The two mounting seats 101 are respectively used to connect the two opposite side walls of the housing 20. The two ends of the mounting rod 102 are respectively connected to the two mounting seats 101. The thermally conductive elastic element 200 is provided with a sleeve hole and is slidably sleeved on the mounting rod 102 through the sleeve hole.

[0050] In this embodiment, the thermally conductive elastic element 200 is provided with a sleeve hole and is slidably sleeved on the mounting rod 102 through the sleeve hole. In this way, the position of the thermally conductive elastic element 200 can be appropriately adjusted according to the distance between two adjacent battery cells 300, so that the position of the thermally conductive elastic element 200 and the corresponding battery cell 300 are more adapted, thereby making the contact and insertion effect between the thermally conductive elastic element 200 and the corresponding battery cell 300 better, the contact between the battery cell 300 and the thermally conductive elastic element 200 is tighter, the heat conduction effect is better, and thus the heat dissipation effect of the battery is better.

[0051] refer to Figure 2 As shown, in some embodiments of this utility model, the mounting base 101 includes a first plate 103 and a second plate 104. The first plate 103 can be vertically arranged and is used to be attached to the side wall of the housing 20. The second plate 104 can be connected to the top of the first plate 103. The second plate 104 is provided with a first waist-shaped hole 105. The first waist-shaped hole 105 extends along the length direction of the mounting rod 102. The two ends of the mounting rod 102 are respectively provided with connecting plates 106. The connecting plates 106 are attached to the top surface of the second plate 104, and a first fastener 107 is installed between the connecting plates 106 and the second plate 104. The first fastener 107 passes through the first waist-shaped hole 105.

[0052] In this embodiment, the mounting base 101 is provided with a first plate 103 for easy connection to the side wall of the housing 20. The mounting base 101 is provided with a second plate 104, and the second plate 104 is provided with a first oblong hole 105. The mounting rod 102 is provided with a connecting plate 106 for easy connection between the mounting rod 102 and the mounting base 101 via a first fastener 107. Moreover, the first oblong hole 105 extends along the length direction of the mounting rod 102, so that the mounting rod 102 can be appropriately adjusted along its own length direction, thereby making the position of the thermally conductive elastic element 200 and the corresponding battery cell 300 more compatible, and the contact and insertion effect between the thermally conductive elastic element 200 and the corresponding battery cell 300 better. This makes the contact between the battery cell 300 and the thermally conductive elastic element 200 tighter, and the heat conduction effect better, thus making the heat dissipation effect of the battery better.

[0053] refer to Figure 2As shown, in some embodiments of this utility model, the first plate 103 is provided with a second waist-shaped hole 108, the second waist-shaped hole 108 extends in the horizontal direction, and the extension direction of the second waist-shaped hole 108 is perpendicular to the extension direction of the first waist-shaped hole 105. The first plate 103 is connected to the side wall of the box 20 by a second fastener, and the second waist-shaped hole 108 is for the second fastener to pass through.

[0054] In this embodiment, the first plate 103 is provided with a second oblong hole 108, which facilitates the connection between the first plate 103 and the side wall of the housing 20 through the second fastener. Moreover, the second oblong hole 108 extends horizontally, and the extension direction of the second oblong hole 108 is perpendicular to the extension direction of the first oblong hole 105. In this way, the position of the heat dissipation component 10 can be appropriately adjusted along the width direction of the cell 300, so that the first abutting part 201 of the thermally conductive elastic member 200 abuts the corresponding cell 300 more appropriately, and the second abutting part 202 of the thermally conductive elastic member 200 abuts the side wall of the housing 20 more appropriately, thereby improving the heat conduction effect and thus improving the heat dissipation effect of the battery.

[0055] refer to Figure 2 As shown, in some embodiments of this utility model, the thermally conductive elastic element 200 and the mounting rod 102 are fixed relative to each other along the circumference of the mounting rod 102. For example, the cross-section of the mounting rod 102 in the length direction can be polygonal, and the sleeve hole can be a polygonal hole.

[0056] In this way, the thermally conductive elastic element 200 can be prevented from rotating freely relative to the mounting rod 102, thereby reducing the contact effect between the first contact part 201 and the cell 300 and the contact effect between the second contact part 202 and the side wall of the housing 20, resulting in better thermal conductivity and thus better heat dissipation of the battery.

[0057] refer to Figure 2 As shown, in some embodiments of this utility model, the mounting rod 102 includes two rod units 109, with their adjacent ends interlocked. When the two rod units 109 are separated, the thermally conductive elastic element 200 can be removed from the adjacent ends of the two rod units 109. For example, one of the adjacent ends of the two rod units 109 may have an insertion hole, and the other may have an insertion block inserted into the insertion hole.

[0058] When it is necessary to clean, repair, replace, or increase or decrease the quantity of the thermally conductive elastic element 200, the two rod units 109 are separated from each other. Then the thermally conductive elastic element 200 can be removed from the end of the two rod units 109 that are close to each other, which makes it convenient to clean, repair, replace, or increase or decrease the quantity of the thermally conductive elastic element 200, and improves its practicality.

[0059] The battery according to a second aspect embodiment of the present invention includes the heat dissipation component 10 described in the first aspect embodiment.

[0060] For example, the battery may also include a housing 20 and a cell module 30. There may be two heat dissipation components 10 installed in the housing 20. The two heat dissipation components 10 are located on opposite sides of the cell module 30, and the thermally conductive elastic elements 200 of the two heat dissipation components 10 abut against opposite sides of the cell 300 in the width direction.

[0061] By employing the heat dissipation assembly 10 of the first aspect embodiment of this utility model, since multiple thermally conductive elastic elements 200 are individually arranged and the thermally conductive elastic elements 200 are elastic, and the first abutting portion 201 and the second abutting portion 202 of the thermally conductive elastic elements 200 bend and extend downward or upward in a direction away from each other, the thermally conductive elastic elements 200 can individually generate large elastic deformation along the width direction of the battery cell 300. Therefore, even if the same side of multiple battery cells 300 is misaligned, the first abutting portion 201 and the second abutting portion 202 of the thermally conductive elastic elements 200 can still tightly abut against the side of the battery cell 300 in the width direction and the inner side wall of the housing 20, respectively, resulting in better heat conduction and thus better heat dissipation of the battery. Moreover, the thermally conductive elastic elements 200 can play an elastic buffering role, thus preventing the battery cell module 30 from being damaged by excessive impact when the side wall of the housing 20 is impacted.

[0062] It should be noted that since the battery can adopt all the technical solutions of the heat dissipation component 10 of the first aspect embodiment, it has at least all the beneficial effects brought about by the technical solutions of the first aspect embodiment. These additional beneficial effects will not be elaborated here.

[0063] It is understood that other components and operations of the battery according to the embodiments of the present invention are known to those skilled in the art and will not be described in detail here.

[0064] The electric two-wheeled vehicle according to a third aspect of the present invention includes the battery described in the second aspect of the present invention.

[0065] According to the electric two-wheeled vehicle of the present invention, by adopting the battery of the second aspect embodiment of the present invention, since multiple thermally conductive elastic elements 200 are individually arranged and the thermally conductive elastic elements 200 are elastic, and the first abutting portion 201 and the second abutting portion 202 of the thermally conductive elastic elements 200 bend and extend downward or upward in a direction away from each other, the thermally conductive elastic elements 200 can individually generate large elastic deformation along the width direction of the battery cell 300. Therefore, even if the same side of multiple battery cells 300 is misaligned, the first abutting portion 201 and the second abutting portion 202 of the thermally conductive elastic elements 200 can still tightly abut against the side of the battery cell 300 in the width direction and the inner side wall of the housing 20, respectively, resulting in better heat conduction and thus better heat dissipation of the battery. Moreover, the thermally conductive elastic elements 200 can play an elastic buffering role, so that when the side wall of the housing 20 is hit, the battery cell module 30 can be prevented from being damaged by excessive impact force.

[0066] It should be noted that since the electric two-wheeled vehicle can adopt all the technical solutions of the heat dissipation component 10 of the first aspect embodiment, it has at least all the beneficial effects brought about by the technical solutions of the first aspect embodiment. These additional beneficial effects will not be elaborated here.

[0067] It is understood that other components and operations of the electric two-wheeler according to the embodiments of the present invention are known to those skilled in the art and will not be described in detail here.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
