[0001] This application relates to the field of two-wheeled vehicles, and in particular to a cooling system, a battery, and an electric two-wheeled vehicle. Background Technology

[0002] Electric two-wheelers can currently use passive cooling methods by using heat sinks connected to the battery body. For example, the side wall of the battery casing has through holes, and the heat sink passes through the through holes to transfer the heat inside the battery to the outside of the battery casing in hot weather. However, in some areas with large temperature differences, in low-temperature environments, the presence of the heat sink will cause the cold air in the environment to be quickly conducted to the battery, causing the battery to affect its working performance due to the low temperature of the cell. Utility Model Content

The heat dissipation element is movably and adjustably disposed in the receiving cavity, with one end extending to the outside of the mounting portion. The heat dissipation element can switch between a first state of contact with the heat-conducting element and a second state of separation from the heat-conducting element when it moves.

[0007] A temperature detection unit is used to detect the temperature inside the housing;

[0030] In the description of this application, it should be noted that, unless otherwise explicitly defined, terms such as "setup," "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 application in conjunction with the specific content of the technical solution.

[0031] The technical solution of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are some embodiments of this application, not all embodiments.

[0032] The following is for reference. Figures 1 to 5 This invention describes a heat dissipation system, a battery, and an electric two-wheeler according to embodiments of the present invention.

[0033] like Figure 1 As shown, Figure 1 This is a system diagram of a heat dissipation system according to an embodiment of the present invention. The heat dissipation system includes:

[0034] 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 communicates with the through hole 101.

[0035] 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 within the housing 100. The heat-conducting element 302 is connected to the body portion 301 and 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. When the heat dissipation element 303 moves, it can switch between a first state of contacting the heat-conducting element 302 and a second state of separation from the heat-conducting element 302.

[0036] Temperature detection unit 601 is used to detect the temperature inside housing 100;

[0037] The control unit 602 is electrically connected to the temperature detection unit 601;

[0038] The display unit 603 is electrically connected to the control unit 602.

[0039] In this embodiment, by setting a heat sink 303 that can switch states, the battery body can effectively dissipate heat in high-temperature environments in summer and reduce the impact of ambient temperature on the battery cell assembly in cold environments in winter, thereby effectively improving the overall performance of the battery in cold environments. At the same time, the temperature detection unit 601 can detect the temperature inside the casing 100, thereby knowing the temperature of the battery cell, and the display unit 603 can effectively view the temperature of the battery cell, so that the user can complete the movement operation of the heat sink 303 as accurately as possible, avoiding the situation that heat dissipation cannot be effectively achieved in high-temperature environments and the battery cell performance cannot be effectively improved in low-temperature environments.

[0040] For details, please refer to Figures 1 to 5 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 into 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.

[0041] The aforementioned through hole 101 is provided on the housing 100 of the battery body.

[0042] The aforementioned housing 100 is used to install components such as battery cells.

[0043] The temperature detection unit 601 mentioned above includes at least one temperature sensor, which is disposed on the outer surface of the battery cell and / or on the inner surface of the housing 100, thereby realizing the detection of the battery cell temperature.

[0044] The control unit 602 mentioned above can be the main controller carried by the electric two-wheeler itself, or a separate independent main controller can be set up.

[0045] The aforementioned display unit 603 can be used to monitor the cell temperature in real time, allowing users to manually move the heat sink 303 based on the cell temperature and ambient temperature. Furthermore, real-time monitoring of the cell temperature allows for early detection of significant temperature anomalies, preventing users from being informed only after the cell module has caught fire, thereby reducing personal injury and property damage caused by fire.

[0046] The ambient temperature can be directly viewed by the user through a smart mobile device or temperature detection product. Understandably, when the ambient temperature is low, the cell temperature can usually be manually checked, and then the heat sink 303 can be moved to enter the second state. When the temperature is high, it is not necessary to move the heat sink 303 to enter the second state, and the heat sink 303 can be kept in the first state.

[0047] In some implementations, the temperature data detected by the temperature detection unit 601 is compared with a preset temperature threshold to determine whether overheating has occurred. Then, a warning message can be sent through the display unit 603 to effectively inform the user of the danger and prevent the user from not being aware of the danger in time.

[0048] In some embodiments, the heat dissipation system further includes:

[0049] A heat-conducting structure is installed on the vehicle body, with one end of the heat-conducting structure abutting against the heat sink 303;

[0050] The heat dissipation unit 700 is installed on the vehicle body and is used to dissipate heat from the heat conduction structure.

[0051] The end of the aforementioned heat-conducting structure near the battery compartment can be provided with an abutment part. The abutment part abuts against the heat sink 303, thereby achieving heat conduction of the heat sink 303. It can be understood that the larger the contact area between the heat sink 303 and the abutment part, the higher the heat conduction efficiency.

[0052] When the heat sink 303 is configured as a strip-shaped structure, a sheet-shaped structure, or similar structure, the contact portion of the heat-conducting structure can be configured as a sheet-shaped structure, with the heat-conducting structure abutting against the side of the heat sink 303. This ensures effective heat transfer without hindering the effective movement of the heat sink 303. Alternatively, the contact portion of the heat-conducting structure can be configured as a slot 305 structure, allowing the heat sink 303 to slide within the slot 305. It can be understood that to reduce friction between the heat sink 303 and the contact portion during movement, lubricating substances such as grease can be added to the contact surface.

[0053] The end of the aforementioned heat-conducting structure furthest from the battery compartment can extend to both sides under the vehicle seat, facilitating the installation of the heat dissipation unit 700. The heat dissipation unit 700 then rapidly dissipates heat from the heat-conducting structure. It should be noted that heat dissipation holes 101 can be provided on the outer shell of the vehicle body corresponding to the location of the heat dissipation unit 700, enabling the heat dissipation unit 700 to dissipate heat efficiently.

[0054] The aforementioned heat-conducting structure can be made of metal or other materials with high thermal conductivity to improve heat conduction efficiency.

[0055] In this embodiment, the heat dissipated by the heat sink 303 is discharged out of the housing 100 through the heat conduction structure, thereby effectively reducing the adverse effects of the enclosed space on battery heat dissipation. The heat dissipation unit 700 is then used to dissipate heat from the heat conduction structure, further accelerating the heat exchange efficiency of the heat conduction structure, thereby effectively reducing the risk of fire in high-temperature environments.

[0056] In some embodiments, the heat dissipation unit 700 includes:

[0057] A semiconductor cooling chip, electrically connected to the control unit 602, is used to dissipate heat from the heat-conducting structure;

[0058] A cooling fan, electrically connected to the control unit 602, is used to deliver the heat generated by the semiconductor cooling chip to the outside of the vehicle.

[0059] The cooling side of the aforementioned thermoelectric cooler can be bonded to the heat-conducting structure with thermally conductive adhesive, thereby directly and effectively cooling the heat-conducting structure. In particular, compared to the heat-conducting structure passively conducting heat through a cooling fan, the cooling efficiency is higher. At the same time, by placing a cooling fan on the heat-dissipating side of the thermoelectric cooler, the heat generated by the thermoelectric cooler during the cooling process can be conducted to the outside of the vehicle.

[0060] The cooling side of the aforementioned semiconductor cooling chip faces the vehicle body, while the heating side faces the vehicle body. A through hole 101 is provided on the vehicle body shell in the area corresponding to the cooling side of the semiconductor cooling chip to facilitate rapid heat dissipation by the fan.

[0061] In some embodiments, the heat dissipation system further includes:

[0062] The audible and visual alarm unit 604 is installed on the vehicle body and is electrically connected to the control unit 602.

[0063] In this embodiment, the sound and light alarm unit 604 can be used to provide sound and light alarms, thereby avoiding the situation where the user cannot detect the alarm in time when the display unit 603 is used to display the alarm.

[0064] In some embodiments, the heat dissipation system further includes:

[0065] The communication module 605 is mounted on the vehicle body and is electrically connected to the control unit 602.

[0066] In this embodiment, the communication module 605 can transmit local temperature information, alarm information and other information to a remote location for remote monitoring. It also facilitates timely notification in case of an emergency, enabling a rapid response and minimizing personal and property losses.

[0067] In some embodiments, the heat dissipation system further includes:

[0068] The ambient temperature module 606 is electrically connected to the control unit 602 and is used to detect the ambient temperature outside the vehicle.

[0069] In this embodiment, by setting an ambient temperature module 606, the ambient temperature outside the vehicle can be collected and transmitted to the control unit 602, and further displayed through the display unit 603, so that the user can directly understand the ambient temperature without having to view it through a third product, thereby improving the user experience.

[0070] In some embodiments, the heat dissipation system further includes:

[0071] The closed-position detection unit 607 is electrically connected to the control unit 602 and is used to detect the contact state between the heat sink 303 and the heat conductor 302.

[0072] The aforementioned closure detection unit 607 can employ a pressure sensor. By placing a pressure sensor on the surface of the heat-conducting component 302 that contacts the heat sink 303, the movement of the heat sink 303 into position can be directly determined by detecting pressure changes. Furthermore, there are many other ways to detect the contact state between the heat sink 303 and the heat-conducting component 302, such as using an infrared sensor, a magnetic sensor, etc.

[0073] When the aforementioned closure detection unit 607 is configured as a pressure sensor, a sensor mounting groove can be provided on the side of the heat-conducting component 302 near the heat sink 303, and a spring can be provided at the bottom of the mounting groove. A mounting seat that can slide along the sensor mounting groove can be provided on the top of the spring. The pressure sensor is located on the side of the mounting seat facing the heat sink 303. When the heat sink 303 moves towards the heat-conducting component 302, it will come into contact with the pressure sensor and continuously squeeze the pressure sensor. The spring will also be further compressed, thereby gradually increasing the pressure detected by the pressure sensor. When the detected pressure value exceeds the preset pressure threshold, it can be confirmed that the heat sink 303 has moved into place, that is, the heat sink 303 and the heat-conducting component 302 have completed contact.

[0074] In some implementations, reference Figure 2 Multiple through holes 101 are provided, multiple heat-conducting components 302 are provided and are respectively inserted through multiple through holes 101, and multiple heat dissipation components 303 are provided, and multiple heat dissipation components 303 can move to contact multiple heat-conducting components 302 respectively.

[0075] In this embodiment, multiple heat-conducting components 302 and heat-dissipating components 303 are provided, thereby making the heat dissipation more uniform and the heat dissipation effect better.

[0076] In some implementations, reference Figure 3 , Figure 4 The heat dissipation component 300 also includes:

[0077] The sliding part 304 is slidably installed in the receiving cavity 201. Multiple heat sinks 303 are disposed on the sliding part 304. When the sliding part 304 slides, it can drive the multiple heat sinks 303 to switch synchronously between the first state and the second state.

[0078] The outer side wall of the sliding part 304 in the sliding direction can fit against the corresponding inner side wall of the receiving cavity 201, so that the sliding part 304 can be slidably installed in the receiving cavity 201. In this embodiment, by sliding and adjusting the sliding part 304, all heat sinks 303 can be switched synchronously between the first state and the second state, making the operation more convenient and saving more time and effort.

[0079] It should be noted that in some implementations, multiple heat sinks 303 can be moved and adjusted individually.

[0080] In some implementations, reference Figure 3 , Figure 4 The battery also includes:

[0081] At least one limiting member 400 is provided between the sliding part 304 and the mounting part 200. When the sliding part 304 slides to the point where the plurality of heat dissipation members 303 are in the first state and the second state, the limiting member 400 restricts the sliding part 304 from sliding.

[0082] In this embodiment, when the sliding part 304 slides to the point where the plurality of heat sinks 303 are in the first state and the second state, the limiting member 400 restricts the sliding part 304 from sliding, thereby preventing the heat sinks 303 from sliding arbitrarily when in the first state and the second state, which would reduce the heat dissipation effect or reduce the effect of limiting the transfer of external cold energy to the housing 100.

[0083] In some implementations, reference Figure 3 , Figure 4 The limiting member 400 is installed on the mounting part 200. The limiting member 400 is set as a spring retainer. 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 make the multiple heat sinks 303 in the first state and the second state, the limiting member 400 is respectively locked in the two corresponding slots 305.

[0084] In this embodiment, during the sliding process of the sliding part 304, the spring retaining ball elastically contracts to avoid interfering with the sliding of the sliding part 304. When the sliding part 304 slides to the point where the multiple heat dissipation components 303 are in the first and second states, the limiting component 400 elastically extends and is respectively locked 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.

[0085] 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. In addition, the limiting member 400 can also be other structures, such as a limiting pin.

[0086] In some implementations, reference Figure 3 , Figure 4 The housing 100 has a mounting sidewall 102, a plurality of through holes 101 are provided on the mounting sidewall 102 and arranged in a horizontal direction, the mounting part 200 is connected to the outer surface of the mounting sidewall 102, the receiving cavity 201 is provided through the side opposite to the mounting sidewall 102, and the sliding part 304 is slidably mounted on the side opposite to the mounting sidewall 102 of the receiving cavity 201 along the thickness direction of the mounting sidewall 102.

[0087] The configuration in this embodiment not only improves heat dissipation but also makes it easier for staff to slide the sliding part 304.

[0088] 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.

[0089] In some implementations, reference Figure 3 , Figure 4 , Figure 5 The receiving cavity 201 has a plurality of receiving grooves 202 formed on the side 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:

[0090] The isolation component 500 is movably disposed in the mounting section 200. When the heat sink 303 moves to the second state, the isolation component 500 can move to the side opposite to the mounting sidewall 102 that covers all the receiving slots 202.

[0091] The side of the heat-conducting component 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 component 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 component 302, the isolation 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.

[0092] In some implementations, reference Figure 3 , Figure 4 , Figure 5 The top of the mounting section 200 is provided with a clearance groove 203, which connects to the receiving cavity 201 and extends along the arrangement direction of the plurality of through holes 101. The isolation assembly 500 includes:

[0093] 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.

[0094] Multiple isolation plates 502 are connected to the bottom surface of the moving strip 501 and arranged along the extending direction of the relief groove 203. The isolation plates 502 pass through the relief groove 203 and extend into the receiving cavity 201.

[0095] When the heat sink 303 moves to the second state, the moving bar 501 can move to position the multiple isolation plates 502 on the moving paths of the multiple heat sinks 303 and cover the side of the multiple receiving slots 202 away from the mounting sidewall 102, and to position the multiple isolation plates 502 on the side of the moving paths of the multiple heat sinks 303, so as to remove the cover of the multiple receiving slots 202.

[0096] In this embodiment, by moving the adjusting moving bar 501 along the extension direction of the relief groove 203, multiple isolation 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 isolation plates 502 can be moved synchronously to the side opposite to the mounting sidewall 102 that is located on the movement path of the multiple heat sinks 303 and covers the 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 isolation plates 502 can also be moved synchronously to the side that is located on the movement path of the multiple heat sinks 303, thereby removing the cover of the 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.

[0097] 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 extending direction of the relief groove 203. When the moving bar 501 moves to the desired position along the extending direction of the relief groove 203, a fastener 503 can be installed between the moving bar 501 and the corresponding mounting hole 204 to lock the moving bar 501. In addition, in some other embodiments of this utility model, the isolation component 500 may also be other structures. For example, a cover plate may be provided on the bottom surface of the moving bar 501, and the cover plate may be provided with multiple relief holes arranged along the extending direction of the relief groove 203.

[0098] In some implementations, reference Figure 3 , Figure 4 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.

[0099] In this embodiment, when the heat sink 303 moves to the first state, the heat conduction component 302 and the heat sink 303 are interlocked, resulting in tighter contact, a larger contact area, and better heat conduction effect.

[0100] This utility model embodiment also provides a battery, which includes the above-described heat dissipation system.

[0101] It should be noted that since the battery can adopt all the technical solutions of the above-mentioned heat dissipation system, it has at least all the beneficial effects brought by the above-mentioned heat dissipation system technical solutions. These additional beneficial effects will not be elaborated here.

[0102] This utility model embodiment also provides an electric two-wheeled vehicle, which includes the battery described above.

[0103] It should be noted that since electric two-wheeled vehicles can adopt all the above-mentioned battery technologies, they have at least all the beneficial effects brought about by the above-mentioned battery technologies. These additional beneficial effects will not be elaborated here.
