[0035] The following is for reference. Figures 1 to 4 This invention describes a battery and an electric two-wheeler according to embodiments of the present invention.
[0036] like Figure 1 and Figure 4 As shown, the battery according to the first aspect of the present invention includes a housing 100, a mounting portion 200, and a heat dissipation assembly 300.
[0037] The housing 100 has an installation cavity inside, which is used to install components such as battery cells. The top of the housing 100 may be provided with a cover. The housing 100 is provided with a through hole 101, which may be one or more. The through hole 101 may be provided on the side wall of the housing 100.
[0038] The mounting part 200 is connected to the outer surface of the housing 100. The mounting part 200 is provided with a receiving cavity 201, which is connected to the through hole 101. One side of the receiving cavity 201 can be through-hole, for example, the side of the receiving cavity 201 away from the housing 100 can be through-hole.
[0039] The heat dissipation assembly 300 includes a body portion 301, a heat-conducting element 302, and a heat dissipation element 303. The body portion 301 is disposed inside the housing 100 and can contact components such as the battery cell. The heat-conducting element 302 is connected to the body portion 301, passes through the through hole 101, and extends into the receiving cavity 201. The heat dissipation element 303 is movably and adjustably disposed in the receiving cavity 201, and one end of the heat dissipation element 303 extends to the outside of the mounting portion 200. For example, the side of the heat dissipation element 303 facing away from the housing 100 can pass through the receiving cavity 201 and extend to the outside of the mounting portion 200.
[0040] The heat sink 303 can switch between a first state and a second state when it moves. When the heat sink 303 is in the first state, it contacts the heat conductor 302 to facilitate the direct transfer of heat between the heat sink 303 and the heat conductor 302. When the heat sink 303 is in the second state, it separates from the heat conductor 302, thereby avoiding the direct transfer of heat between the heat sink 303 and the heat conductor 302.
[0041] In this invention, the housing 100 is used to install components such as battery cells. In hot weather, the heat sink 303 can be moved and adjusted to a first state. In this state, the heat sink 303 is in contact with the heat conductor 302, so that the heat inside the housing 100 can be transferred to the heat conductor 302 through the main body 301, and then transferred to the heat sink 303 through the heat conductor 302, and finally dissipated through the heat sink 303 to dissipate heat inside the housing 100. In cold weather, the heat sink 303 can be moved and adjusted to a second state. In this state, the heat sink 303 is separated from the heat conductor 302, so as to prevent external cold from being transferred to the heat conductor 302 through the heat sink 303 and then entering the housing 100, which would cause the temperature of the battery cells and other components inside the housing 100 to be too low and affect their working performance.
[0042] In some embodiments of this utility model, such as Figure 1 and Figure 4 As shown, multiple through holes 101 are provided, multiple heat-conducting elements 302 are provided and respectively pass through multiple through holes 101, and multiple heat dissipation elements 303 are provided, and the multiple heat dissipation elements 303 can be moved to contact the multiple heat-conducting elements 302 respectively. In this embodiment, multiple heat-conducting elements 302 and heat dissipation elements 303 are provided, thereby making the heat dissipation more uniform and the heat dissipation effect better.
[0043] In some embodiments of this utility model, such as Figures 1 to 3 As shown, the heat dissipation assembly 300 also includes a sliding portion 304, which is slidably installed within the receiving cavity 201. Multiple heat dissipation components 303 are disposed on the sliding portion 304. When the sliding portion 304 slides, it can drive the multiple heat dissipation components 303 to switch synchronously between a first state and a second state. For example, the outer sidewall of the sliding portion 304 in the sliding direction can be fitted against the corresponding inner sidewall of the receiving cavity 201 to achieve slidable installation of the sliding portion 304 within the receiving cavity 201. In this embodiment, by adjusting the sliding portion 304, all heat dissipation components 303 can switch synchronously between the first and second states, making operation more convenient and saving time and effort.
[0044] It should be noted that in some other embodiments of this utility model, multiple heat sinks 303 can also be moved and adjusted individually.
[0045] In some embodiments of this utility model, such as Figure 2 and Figure 3As shown, the battery also includes at least one limiting member 400, which is disposed between the sliding portion 304 and the mounting portion 200. When the sliding portion 304 slides to position the plurality of heat dissipation components 303 in the first and second states, the limiting member 400 restricts the sliding portion 304 from sliding. In this embodiment, when the sliding portion 304 slides to position the plurality of heat dissipation components 303 in the first and second states, the limiting member 400 restricts the sliding portion 304 from sliding, thereby preventing the heat dissipation components 303 from sliding arbitrarily in the first and second states, which would reduce the heat dissipation effect or reduce the effect of limiting the transfer of external cold energy to the housing 100.
[0046] In some embodiments of this utility model, such as Figure 2 and Figure 3 As shown, the limiting member 400 is installed on the mounting part 200. The limiting member 400 is configured as a spring-loaded ball. The sliding part 304 has two slots 305 corresponding to the limiting member 400. The two slots 305 corresponding to the same limiting member 400 are arranged along the sliding direction of the sliding part 304. When the sliding part 304 slides to the point where multiple heat sinks 303 are in the first and second states, the limiting member 400 is respectively engaged in the two corresponding slots 305. During the sliding process of the sliding part 304, the spring-loaded ball elastically contracts to avoid interfering with the sliding of the sliding part 304. When the sliding part 304 slides to the point where multiple heat sinks 303 are in the first and second states, the limiting member 400 elastically extends and is respectively engaged in the two corresponding slots 305, thereby restricting the sliding part 304 from continuing to slide and avoiding reducing the heat dissipation effect or reducing the effect of restricting the transfer of external cold energy to the housing 100.
[0047] It should be noted that the spring-loaded retaining ball includes a mounting cylinder, a spring, and a retaining ball. The mounting cylinder can be located on the side wall of the receiving cavity 201, the spring is installed inside the mounting cylinder, and the retaining ball is connected to the spring. The spring-loaded retaining ball is a common elastically telescopic snap-fit structure, which will not be described in detail here. Additionally, the limiting member 400 can also be other structures, such as a limiting pin.
[0048] In some embodiments of this utility model, such as Figure 3 As shown, the housing 100 has a mounting sidewall 102, with multiple through holes 101 arranged horizontally on the mounting sidewall 102. A mounting portion 200 is connected to the outer surface of the mounting sidewall 102. A receiving cavity 201 is provided through the side of the receiving cavity 201 opposite to the mounting sidewall 102. A sliding portion 304 is slidably mounted on the side of the receiving cavity 201 opposite to the mounting sidewall 102 along the thickness direction of the mounting sidewall 102. This arrangement not only improves heat dissipation but also makes it easier for operators to slide the sliding portion 304.
[0049] It should be noted that a handle 307 may be provided on the side of the sliding part 304 away from the housing 100 to make it more convenient for staff to slide the sliding part 304.
[0050] In some embodiments of this utility model, such as Figure 3 and Figure 4 As shown, a plurality of receiving grooves 202 are formed on the side of the receiving cavity 201 near the mounting sidewall 102. The plurality of receiving grooves 202 are respectively connected to a plurality of through holes 101. A plurality of heat-conducting elements 302 extend into the plurality of receiving grooves 202. The battery also includes a heat insulation component 500, which is movably disposed on the mounting portion 200. When the heat sink 303 moves to the second state, the heat insulation component 500 can move to cover the side of all receiving grooves 202 away from the mounting sidewall 102. For example, the side of the heat-conducting element 302 facing away from the mounting sidewall 102 can be flush with the side of the receiving groove 202 facing away from the mounting sidewall 102, or the side of the heat-conducting element 302 facing away from the mounting sidewall 102 can be closer to the mounting sidewall 102 than the side of the receiving groove 202 facing away from the mounting sidewall 102. When the heat sink 303 moves to the second state, that is, when the heat sink 303 is separated from the heat-conducting element 302, the heat insulation component 500 can move to cover the side of the receiving groove 202 facing away from the mounting sidewall 102. In cold climates, this can further reduce the external cold energy transferred to the heat sink 302 through the heat sink 303 and then to the housing 100, thus preventing damage to components such as the battery cell.
[0051] In some embodiments of this utility model, such as Figure 3 and Figure 4 As shown, the top of the mounting part 200 is provided with a relief groove 203, which connects to the receiving cavity 201 and extends along the arrangement direction of the plurality of through holes 101. The heat insulation assembly 500 includes a movable strip 501 and a plurality of heat insulation plates 502. The movable strip 501 fits against the top surface of the mounting part 200 and covers the relief groove 203. The movable strip 501 can be moved and adjusted along the extension direction of the relief groove 203. The plurality of heat insulation plates 502 are connected to the bottom surface of the movable strip 501 and extend along the extension direction of the relief groove 203. The heat insulation plates 502 are arranged in a directional manner, passing through the relief grooves 203 and extending into the receiving cavity 201; wherein, when the heat dissipation component 303 moves to the second state, the moving bar 501 can move to such that the multiple heat insulation plates 502 are respectively located on the moving paths of the multiple heat dissipation components 303 and respectively cover the side of the multiple receiving grooves 202 away from the mounting sidewall 102, and to such that the multiple heat insulation plates 502 are respectively located on one side of the moving paths of the multiple heat dissipation components 303, so as to remove the covering of the multiple receiving grooves 202.
[0052] It should be noted that the heat insulation panel 502 is made of heat insulation material.
[0053] In this embodiment, by moving the adjusting moving bar 501 along the extension direction of the relief groove 203, multiple heat insulation plates 502 can be moved synchronously along the extension direction of the relief groove 203. Thus, when the heat sink 303 moves to the second state, multiple heat insulation plates 502 can be moved synchronously to the side opposite to the mounting sidewall 102 that is located on the movement path of multiple heat sinks 303 and covers multiple receiving grooves 202. In cold climates, this can further reduce the transfer of external cold energy through the heat sink 303 to the heat conductor 302, and then to the housing 100, which could damage components such as the battery cell. In addition, by moving the adjusting moving bar 501 along the extension direction of the relief groove 203, multiple heat insulation plates 502 can also be moved synchronously to the side that is located on the movement path of multiple heat sinks 303, thereby removing the cover of multiple receiving grooves 202. This makes it easier to move the heat sink 303 to the first state that is in contact with the heat conductor 302, making the operation simpler and more convenient.
[0054] It should be noted that the top of the mounting part 200 may be provided with multiple mounting holes 204, which can be arranged along the extension direction of the relief groove 203. When the moving strip 501 moves to the desired position along the extension direction of the relief groove 203, a fastener 503 can be installed between the moving strip 501 and the corresponding mounting hole 204 to lock the moving strip 501. In addition, in some other embodiments of this utility model, the heat insulation component 500 may also have other structures. For example, a cover plate may be provided on the bottom surface of the moving strip 501, and the cover plate may be provided with multiple relief holes arranged along the extension direction of the relief groove 203.
[0055] In some embodiments of this utility model, such as Figure 3 As shown, one of the heat-conducting component 302 and the heat-dissipating component 303 is provided with a slot 306, and the other can be inserted into the slot 306 when the heat-dissipating component 303 moves to the first state. In this embodiment, when the heat-dissipating component 303 moves to the first state, the heat-conducting component 302 and the heat-dissipating component 303 are interlocked, resulting in tighter contact, a larger contact area, and better heat conduction.
[0056] The electric two-wheeled vehicle according to a second aspect embodiment of the present invention includes the battery described in the first aspect embodiment.
[0057] According to the embodiments of the present invention, the electric two-wheeled vehicle uses a battery from the first aspect of the present invention. The housing 100 is used to install components such as battery cells. In hot weather, the heat sink 303 can be moved and adjusted to a first state. In this state, the heat sink 303 is in contact with the heat conductor 302, so that the heat inside the housing 100 can be transferred to the heat conductor 302 through the main body 301, and then transferred to the heat sink 303 through the heat conductor 302, and finally dissipated through the heat sink 303 to dissipate heat inside the housing 100. In cold weather, the heat sink 303 can be moved and adjusted to a second state. In this state, the heat sink 303 is separated from the heat conductor 302, so as to prevent external cold from being transferred to the heat conductor 302 through the heat sink 303 and then entering the housing 100, which would cause the temperature of the battery cells and other components inside the housing 100 to be too low and affect the working performance.
[0058] It should be noted that since electric two-wheeled vehicles can adopt all the technical solutions of the batteries in the first aspect embodiment described above, they have at least all the beneficial effects brought about by the technical solutions in the first aspect embodiment described above. These additional beneficial effects will not be elaborated here.
[0059] 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.
[0060] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. 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.
