For example, the side wall of the battery casing has through holes through which the heat sink passes to transfer heat from inside the battery to the outside of the battery casing in hot weather. However, in low-temperature environments, the presence of the heat sink can cause the cold air in the environment to be quickly conducted into the battery, resulting in the battery's performance being affected due to excessively low cell temperature.

The heat dissipation assembly has a mounting chamber that penetrates the heat-conducting element and the body and communicates with the interior of the housing.

[0007] An electric telescopic mechanism is disposed within the mounting chamber and / or the housing, and the telescopic end of the electric telescopic mechanism is connected to the heat sink; the electric telescopic mechanism is used to push the heat sink to move through the telescopic end, so that the heat sink can switch between a first state of contacting the heat conductor and a second state of separation from the heat conductor when it moves;

[0029] 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.

[0030] The following is for reference. Figures 1 to 4 This invention describes an automatic heat dissipation system, a battery, and an electric two-wheeler according to embodiments of the present invention.

[0031] like Figure 1 As shown, Figure 1 This is a system diagram of an automatic heat dissipation system according to an embodiment of the present invention. The automatic heat dissipation system includes:

[0032] 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.

[0033] The heat dissipation assembly 300 includes a body 301, a heat-conducting element 302, and a heat dissipation element 303. The body 301 is disposed inside the housing 100. The heat-conducting element 302 is connected to the body 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. The heat dissipation assembly 300 is provided with a mounting chamber 305, which passes through the heat-conducting element 302 and the body 301 and communicates with the inside of the housing 100.

[0034] An electric telescopic mechanism is provided in the mounting chamber 305 and / or the housing 100. The telescopic end of the electric telescopic mechanism is connected to the heat sink 303. The electric telescopic mechanism is used to push the heat sink 303 to move through the telescopic end, so that the heat sink 303 can switch between a first state of contacting the heat conductor 302 and a second state of separation from the heat conductor 302 when it moves.

[0035] Temperature detection unit 401 is used to detect the temperature of the battery cell inside the housing 100;

[0036] The control unit 402 is electrically connected to the temperature detection unit 401.

[0037] 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. Furthermore, the temperature detection unit 401 can detect the temperature inside the casing 100, that is, obtain the battery cell temperature, and then adjust the extension state of the extension end of the electric telescopic mechanism according to the battery cell temperature, thereby realizing the electric movement of the heat sink, so that the user can keep the battery in a reasonable heat dissipation mode without manual intervention, improving the user experience.

[0038] For details, please refer to Figures 2 to 4 When the cell temperature is high, 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. When the cell temperature is low, 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 energy from being transferred to the heat conductor 302 through the heat sink 303 and then entering the housing 100, causing the temperature of the cell and other components inside the housing 100 to be too low and affecting the working performance.

[0039] Understandably, in cold environments, the ambient temperature gradually affects the cell temperature inside the battery casing 100. If the cell temperature is low, it can be assumed that the ambient temperature has already affected the cell temperature inside the battery casing 100, requiring immediate movement of the heat sink 303 to the second state to slow down the rate of temperature decrease. Conversely, if the cell temperature is high, regardless of whether it is in a cold or hot environment, it can be assumed that the cell temperature is high and requires timely heat dissipation, necessitating the movement of the heat sink 303 to the first state. For example, when the cell temperature is below 10 degrees Celsius, the heat sink 303 is separated from the heat conductor 302; when the cell temperature is above 30 degrees Celsius, the heat sink 303 is brought into contact with the heat conductor 302; and when the temperature is between 10 and 30 degrees Celsius, the previous state can be directly followed.

[0040] The aforementioned through hole 101 is provided on the housing 100 of the battery body.

[0041] The aforementioned housing 100 is used to install components such as battery cells.

[0042] The temperature detection unit 401 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.

[0043] The control unit 402 mentioned above can be the main controller carried by the electric two-wheeler itself, or a separate independent main controller can be set up.

[0044] The aforementioned electric telescopic mechanism can be fixedly installed in the installation chamber 305.

[0045] The aforementioned electric telescopic mechanism can use a telescopic motor.

[0046] The drive motor of the aforementioned telescopic motor can be a servo motor, which allows for precise control of the telescopic end's extension and retraction.

[0047] When the electric telescopic mechanism is small in size and / or the installation chamber 305 is large in size, the main body can be directly installed in the installation chamber 305. When the main body is large in size and / or the installation chamber 305 is small in size, part or all of the main body can be installed in the housing 100, and the telescopic end can be placed in the installation chamber 305.

[0048] In some embodiments, the automatic cooling 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 500 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 structure, allowing the heat sink 303 to slide within the slot. 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 a heat dissipation unit 500 to quickly dissipate 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 500, enabling the heat dissipation unit 500 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 500 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 500 includes:

[0057] A semiconductor cooling chip, electrically connected to the control unit 402, is used to dissipate heat from the heat-conducting structure;

[0058] A cooling fan, electrically connected to control unit 402, 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 automatic cooling system further includes:

[0062] The display unit 403 is mounted on the vehicle body and is electrically connected to the control unit 402.

[0063] In this embodiment, the display unit 403 can be used to view information such as cell temperature, ambient temperature, and heat sink status, making it convenient for users to check the working status of the automatic heat dissipation system.

[0064] In some embodiments, the automatic cooling system further includes:

[0065] The audible and visual alarm unit 404 is installed on the vehicle body and is electrically connected to the control unit 402.

[0066] In this embodiment, the sound and light alarm unit 404 can be used to perform sound and light alarms, thereby avoiding the situation where the user cannot detect the alarm in time when the display unit 403 is used to display the alarm.

[0067] In some embodiments, the automatic cooling system further includes:

[0068] The communication module 405 is mounted on the vehicle body and is electrically connected to the control unit 402.

[0069] In this embodiment, the communication module 405 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.

[0070] In some embodiments, the automatic cooling system further includes:

[0071] The ambient temperature module 406 is electrically connected to the control unit 402 and is used to detect the ambient temperature outside the vehicle.

[0072] In this embodiment, by setting an ambient temperature module 406, the ambient temperature outside the vehicle can be collected and transmitted to the control unit 402, and further displayed through the display unit 403, so that the user can directly know the ambient temperature without having to view it through a third-party product, thereby improving the user experience.

[0073] In some embodiments, the automatic cooling system further includes:

[0074] The closed-position detection unit 407 is electrically connected to the control unit 402 and is used to detect the contact state between the heat sink 303 and the heat conductor 302.

[0075] The aforementioned closure detection unit 407 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.

[0076] When the aforementioned closure detection unit 407 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.

[0077] In this embodiment, the contact state between the heat sink 303 and the heat conductor 302 can be detected by the closed-position detection unit 407, thereby knowing whether the telescopic end of the electric telescopic mechanism has moved into position. Furthermore, with the closed-position detection unit 407, the requirements for the drive motor in the electric telescopic mechanism are also reduced, and it is no longer necessary to use a motor that can perform high-precision control of the telescopic distance.

[0078] In some implementations, reference Figures 2 to 4 Multiple through holes 101 are provided, multiple heat-conducting components 302 are provided and are respectively inserted through multiple through holes 101, multiple heat dissipation components 303 are provided, and multiple heat dissipation components 303 can be moved to contact multiple heat-conducting components 302 respectively.

[0079] The heat dissipation component 300 also includes:

[0080] The sliding part 304 is slidably installed in the receiving cavity 201. Multiple heat dissipation components 303 are disposed in the sliding part 304. When the sliding part 304 slides, it can drive the multiple heat dissipation components 303 to switch synchronously between the first state and the second state. At least one heat conduction component 302 is provided with an installation chamber 305. Each installation chamber 305 is provided with an electric telescopic mechanism.

[0081] 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.

[0082] The outer wall of the sliding part 304 in the sliding direction can fit against the corresponding inner 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 any heat sink 303, all heat sinks 303 connected to the sliding part 304 can be switched synchronously between the first state and the second state, reducing the need for an electric telescopic mechanism and simplifying the control logic.

[0083] In some implementations, reference Figures 2 to 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.

[0084] The configuration in this embodiment not only improves heat dissipation but also makes it easier for staff to slide the sliding part 304.

[0085] In some embodiments, one of the heat-conducting element 302 and the heat sink 303 is provided with a slot, and the other can be inserted into the slot when the heat sink 303 is moved to the first state.

[0086] 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.

[0087] This utility model embodiment also provides a battery, which includes the above-described automatic heat dissipation system.

[0088] In this embodiment, by using the heat dissipation component 300 of this utility model, when assembling the battery, firstly, the heat-conducting base plate of the heat dissipation component 300 is attached to the bottom surface inside the battery housing 100. Then, the heat dissipation component 303 is moved above the heat-conducting base plate, and the surface of the heat dissipation connecting plate is made parallel to the surface of the heat-conducting connecting plate, so that multiple heat dissipation fins are aligned with multiple clearance openings. Then, the heat dissipation component 303 is moved outward so that the heat dissipation connecting plate is attached to the inner side of the heat-conducting connecting plate, and multiple heat dissipation fins are respectively inserted through multiple clearance openings and multiple through holes 101 on the side wall of the housing 100. Finally, the heat dissipation connecting plate and the heat-conducting connecting plate are connected. The operation is simple, time-saving and labor-saving.

These additional beneficial effects will not be elaborated here.

Furthermore, other configurations 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.
