Description

Technical Field

[0001] This application relates to the field of two-wheeled vehicles, and in particular to an active warning explosion-proof housing, a battery, and an electric two-wheeled vehicle. Background Technology

[0002] During battery use, if an internal short circuit, thermal runaway, or other abnormal situation occurs in the battery cell, the internal pressure will rise rapidly. When the pressure exceeds the maximum pressure the casing can withstand, the casing may rupture or even explode, seriously threatening the normal operation of equipment and personal safety. Therefore, effectively addressing the problem of pressure rise and even explosion caused by abnormal battery cells has become a key challenge in the field of battery technology, concerning the safety and reliability of battery products. Utility Model Content

[0003] This application aims to propose an active early warning explosion-proof enclosure, battery, and electric two-wheeler that can achieve good explosion-proof effect.

[0004] The active early warning explosion-proof enclosure provided in the first aspect of this application includes:

[0005] The casing has an open top.

[0006] The cover has a first side and a second side, the first side is hinged to one side of the top of the housing, and the second side is connected to an elastic band. The bottom end of the elastic band is detachably connected to the other side of the top of the housing. The cover has a side plate that fits against the outer surface of the housing. The side plate on the second side has a vent groove, and the side wall of the housing covers the inner side of the vent groove. Alternatively, the side wall of the housing has a vent groove, and the side plate on the second side covers the outer side of the vent groove.

[0007] The control unit is housed within the casing;

[0008] A pressure detection unit is electrically connected to the control unit and is disposed inside the housing to detect the pressure inside the housing.

[0009] The battery provided in the second aspect of this application includes the active warning explosion-proof enclosure described in the first aspect of the application.

[0010] The electric two-wheeled vehicle provided in the third aspect of this application includes the battery described in the second aspect of the above-described embodiment.

[0011] The active warning explosion-proof enclosure, battery, and electric two-wheeler of this application embodiment can provide an early warning when the air pressure inside the battery is high. This is because the air pressure detection unit detects an increase in the air pressure inside the enclosure and can provide an early warning to remind the rider to detect the danger as soon as possible, stop in time, and move away to avoid personal injury. At the same time, when the high-pressure airflow inside the enclosure impacts the bottom surface of the cover, the elastic band will stretch elastically under the impact force, and the second side of the cover can move upward. When the vent is provided on the side plate of the second side, the inner cavity of the enclosure can be connected to the external environment through the vent, so that the high-pressure airflow inside the enclosure can be quickly discharged through the vent, further reducing personal and property damage caused by an explosion.

[0026] 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.

[0027] 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.

[0028] The following is for reference. Figures 1 to 5 This application describes an active warning explosion-proof enclosure, a battery, and an electric two-wheeler according to embodiments thereof.

[0029] like Figures 1 to 5 As shown in the figure, the active early warning explosion-proof enclosure of this application embodiment includes:

[0030] The casing 100 has an open top.

[0031] The cover 200 has a first side 201 and a second side 202. The first side 201 is hinged to one side of the top of the housing 100. The second side 202 is connected to an elastic band 203. The bottom end of the elastic band 203 is detachably connected to the other side of the top of the housing 100. The cover 200 is provided with a side plate 204, which fits against the outer surface of the housing 100. The side plate 204 of the second side 202 is provided with a vent groove 205. The side wall of the housing 100 covers the inner side of the vent groove 205. Alternatively, the side wall of the housing 100 is provided with a vent groove 205, and the side plate 204 of the second side 202 covers the outer side of the vent groove 205.

[0032] Control unit 401 is disposed within housing 100;

[0033] The air pressure detection unit 402 is electrically connected to the control unit 401 and is disposed inside the housing 100 to detect the air pressure inside the housing 100.

[0034] In this embodiment, when the air pressure inside the battery is high, the air pressure detection unit 402 detects that the air pressure inside the casing 100 will increase, thus providing an early warning to remind the rider to detect the danger as soon as possible, stop and move away in time, and avoid personal injury. At the same time, when the high-pressure airflow inside the casing 100 impacts the bottom surface of the cover 200, the elastic band 203 will stretch elastically under the impact force, and the second side 202 of the cover 200 can then move upward. When the venting groove 205 is provided on the side plate 204 of the second side 202, the inner cavity of the casing 100 and the external environment can be connected through the venting groove 205, thereby allowing the high-pressure airflow inside the casing 100 to be quickly discharged through the venting groove 205, further reducing personal and property damage caused by the explosion.

[0035] The aforementioned control unit 401 can directly use the core controller of the battery management system, or it can use a separate controller. The specific usage method can be selected based on actual control needs, cost and other factors.

[0036] The aforementioned air pressure detection unit 402 can be installed in any area within the housing 100. The control unit 401 can determine whether the air pressure is abnormal and trigger an alarm by acquiring the air pressure data collected by the air pressure detection unit 402 within the housing 100. For example, an alarm can be triggered if the air pressure exceeds a preset safe air pressure threshold. Multiple alarm methods are available. For instance, an independent alarm module 405 can be set up, controlled by the control unit 401 to trigger the alarm. Alternatively, when the control unit 401 is connected to a wireless communication module, an alarm can also be triggered by sending a message to the rider's smart terminal.

[0037] The aforementioned air pressure detection unit 402 can directly use commonly available pressure detection sensors.

[0038] In some implementations, reference Figure 1 The active warning explosion-proof enclosure also includes:

[0039] The cover pressure relief detection unit 403 is electrically connected to the control unit 401 and is used to detect the vertical movement of the cover 200.

[0040] In this embodiment, the cover pressure relief detection unit 403 is used to detect the vertical movement of the cover 200 to determine whether the vent 303 has been depressurized. On the one hand, an alarm can be triggered in time when the vent 303 is depressurized. On the other hand, the control unit 401 can also trigger an alarm based on the air pressure data detected by the air pressure detection unit 402. If the air pressure is still rising but the vent 303 is still not depressurized, the alarm level can be increased to remind the rider that the current risk of explosion is extremely high.

[0041] In some implementations, reference Figure 3 When a venting groove 205 is provided on the side wall of the housing 100, and the side plate 204 of the second side 202 covers the outside of the venting groove 205, the cover pressure relief detection unit 403 includes:

[0042] An infrared detection sensor is disposed on the side wall of the housing 100 and directly opposite the ventilation slot 205. The infrared detection sensor is electrically connected to the control unit 401. A reflective part is provided on the side plate 204 of the second side 202, which is used to reflect the infrared detection light emitted by the infrared detection sensor.

[0043] In this embodiment, considering the scenario where the vent groove 205 is located on the side wall of the housing 100, the side plate 204 of the second side 202 covers the outside of the vent groove 205. Therefore, an infrared detection sensor can be used to determine whether the vent groove 205 is depressurized by reflecting infrared light. This method is both efficient and cost-effective.

[0044] Specifically, when the ventilation slot 205 is covered, the infrared detection light can be reflected by the side plate 204 back to the receiving module of the infrared detection sensor. When the ventilation slot 205 is not covered, the infrared detection light cannot be reflected by the side plate 204 to the receiving module of the infrared sensor.

[0045] The aforementioned reflective element can increase the intensity of reflection. The reflective element can be a coated reflective layer or a reflective component such as a reflector.

[0046] It should be noted that the infrared detection sensor can also be directly replaced with an infrared ranging module, a visible light ranging module, or other ranging devices that can perform single-point ranging. This allows the determination of whether the vent 205 has been depressurized by directly detecting changes in distance.

[0047] Specifically, when the vent 205 is covered, the distance detected by the ranging device will be less than the distance when the vent 205 is not covered. By detecting the distance, it can be directly determined whether the vent 205 has been depressurized.

[0048] In some implementations, reference Figure 3 The infrared detection sensor emits infrared detection light and is positioned directly at the bottom of the ventilation slot 205.

[0049] In this embodiment, considering that the venting groove 205 is not always completely leaked, the infrared detection light is directed towards the bottom of the venting groove 205. This allows for effective detection of a small amount of air leakage in the venting groove 205, thus avoiding missed or false detections.

[0050] In some embodiments, a partition plate is horizontally disposed inside the housing 100, and the cell module is disposed below the partition plate;

[0051] The cover pressure relief detection unit 403 includes:

[0052] A cover displacement detection sensor is installed on the top of the isolation plate and directly facing the cover 200 to detect the vertical movement distance of the cover 200.

[0053] The aforementioned isolation plate can divide the housing 100 into two spaces, separating the space where the battery cell module is located from the space where electronic control devices are arranged, thereby improving the safety of use.

[0054] The aforementioned cover displacement detection sensor can directly employ ranging devices such as infrared ranging modules, visible light ranging modules, and ultrasonic ranging modules. This allows for the determination of whether the cover 200 is open by directly detecting changes in the distance between the cover 200 and the isolation plate. Furthermore, the vertical movement distance of the cover 200 required to depressurize the vent 205 can be predetermined. Based on this, determining the movement distance of the cover 200 allows for the determination of whether effective depressurization has occurred.

[0055] In some implementations, reference Figure 1 The active warning explosion-proof enclosure also includes:

[0056] Temperature sensor 404 is electrically connected to control unit 401 and is disposed inside housing 100 for detecting temperature inside housing 100.

[0057] In this embodiment, in many scenarios, temperature changes precede air pressure changes. Especially when only a few battery cells fail and the combustion is smoldering, the air pressure usually does not rise quickly. However, by using the temperature sensor 404 to detect the temperature inside the casing 100, overheating can be detected in advance, thus providing an early warning. This allows for maintenance of only some battery cells in certain scenarios without replacing the entire battery. In other words, while achieving explosion-proof warning, the operating cost is effectively reduced.

[0058] In some implementations, reference Figure 1 The active warning explosion-proof enclosure also includes:

[0059] The alarm module 405 is electrically connected to the control unit 401.

[0060] The alarm module 405 mentioned above can sound an alarm independently, so that riders can be aware of the risks as early as possible and avoid dangerous situations.

[0061] The alarm module 405 can directly use an audible and visual alarm device. The audible and visual alarm device can be directly connected to the control unit 401 electrically, or it can use an audible and visual alarm device with Bluetooth connection to connect to the control unit 401 via Bluetooth.

[0062] In some implementations, reference Figure 2 Two elastic bands 203 are provided, located on both sides of the vent groove 205. Specifically, the vent groove 205 can be provided on the side plate 204 of the second side 202 and extends along the length of the side plate 204 of the second side 202. Two elastic bands 203 are provided, located on both sides of the vent groove 205. In this embodiment, this arrangement not only makes the vent groove 205 larger in area and improves the ventilation effect, but also makes the connection between the cover 200 and the shell 100 more stable.

[0063] In some implementations, such as Figures 2 to 5As shown, the active warning explosion-proof enclosure also includes an explosion-proof component 300, which includes a mounting base 301 and an explosion-proof plate 302. The mounting base 301 is installed on the cover 200, for example, it can be connected to the cover 200 by a fastener 313, or it can be snapped onto the cover 200. The mounting base 301 is provided with a through-hole 303, which includes a first hole section 304 and a second hole section 305. The first hole section 304 and the second hole section 305 can be coaxially arranged. The second hole section 305 is located below the first hole section 304, and the diameter of the second hole section 305 is smaller than the diameter of the first hole section 304. When the cover 200 is installed on the top of the housing 100, the top of the first hole section 304 is connected to the outside, and the bottom of the second hole section 305 is connected to the inner cavity of the housing 100. The hole wall of the first hole section 304 is provided with a connecting groove 306, which extends vertically. The explosion-proof plate 302 is slidably installed in the first hole section 304 and covers the top of the second hole section 305. When the explosion-proof plate 302 covers the top of the second hole section 305, the bottom of the connecting groove 306 can be higher than the top of the explosion-proof plate 302 or located outside the explosion-proof plate 302.

[0064] When the airflow enters the second hole section 305 from the inner cavity of the housing 100, the explosion-proof plate 302 is impacted by the high-pressure airflow and slides upward. The explosion-proof plate 302 can be lifted by the airflow to a position higher than the bottom of the connecting groove 306, so that the top of the first hole section 304 can be connected to the second hole section 305 through the connecting groove 306.

[0065] In this embodiment, under normal circumstances, the explosion-proof plate 302 covers the top of the second hole section 305, thereby preventing external dust and rainwater from entering the battery through the vent 303 and affecting the components inside the battery. When the air pressure inside the battery is high, the high-pressure airflow inside the battery enters the second hole section 305 from the bottom end. The explosion-proof plate 302 slides upward under the impact of the high-pressure airflow. When the explosion-proof plate 302 is lifted by the airflow to a position higher than the bottom end of the connecting groove 306, the top end of the first hole section 304 connects to the second hole section 305 through the connecting groove 306, thereby facilitating the rapid discharge of high-pressure airflow and preventing the battery from exploding.

[0066] In addition, a pressure relief detection unit can be set up that is electrically connected to the control unit 401. The pressure relief detection unit can be used to detect the movement of the explosion-proof plate 302 along the axial direction of the vent hole 303, thereby determining whether the explosion-proof plate 302 has been activated.

[0067] In some implementations, the component pressure relief detection unit includes:

[0068] A plate-type pressure sensor is disposed at the bottom of the first hole section 304 and located between the bottom of the first hole section 304 and the explosion-proof plate 302; the plate-type pressure sensor is electrically connected to the control unit 401 and is used to detect the pressure between the bottom of the first hole section 304 and the explosion-proof plate 302.

[0069] In this embodiment, a plate pressure sensor is used to detect the pressure between the bottom of the first hole section 304 and the explosion-proof plate 302 to determine whether the explosion-proof plate 302 has started to depressurize. The detection method is simple, accurate and extremely low cost.

[0070] Specifically, when the explosion-proof plate 302 is not depressurized, it will compress the bottom of the first hole section 304. The plate pressure sensor can detect this compressive force to determine that the explosion-proof plate 302 has not been moved by the airflow. When the explosion-proof plate 302 is depressurized, it will separate from the bottom of the first hole section 304 and no longer compress the bottom of the first hole section 304. At this time, the plate pressure sensor cannot detect the compressive force, thus determining that the explosion-proof plate 302 has been opened by the airflow and has begun to depressurize.

[0071] In some implementations, the component pressure relief detection unit includes:

[0072] The component displacement detection sensor, electrically connected to the control unit 401, is installed on the top of the isolation plate and directly opposite the explosion-proof plate 302, and is used to detect the vertical movement distance of the explosion-proof plate 302.

[0073] In this embodiment, a component displacement detection sensor is used to directly detect the movement distance of the explosion-proof plate 302 to determine whether the explosion-proof plate 302 has started to depressurize, which is a more direct detection method.

[0074] It should be noted that there are many ways to detect whether the explosion-proof panel 302 has performed a pressure relief action, and it is not limited to the aforementioned methods.

[0075] In addition, in some scenarios, the explosion-proof plate 302 may cause the internal air pressure of the battery casing to rise slowly, resulting in repeated opening and closing. Therefore, if the explosion-proof plate 302 depressurizes multiple times within a certain time range, an alarm should be triggered to remind the rider to conduct a risk assessment in a timely manner.

[0076] The displacement detection sensor of the above components can directly adopt ranging devices that can perform distance measurement, such as infrared ranging modules, visible light ranging modules, and ultrasonic ranging modules.

[0077] In some implementations, such as Figure 4 and Figure 5As shown, the explosion-proof component 300 also includes an elastic element 307, which is connected to the hole wall of the first hole segment 304. For example, the elastic element 307 can be integrally formed with the hole wall of the first hole segment 304, welded, or connected by screws. The elastic element 307 elastically abuts against the upper end face of the explosion-proof plate 302. In this embodiment, under normal circumstances, the elastic element 307 elastically abuts against the upper end face of the explosion-proof plate 302 so that the explosion-proof plate 302 can tightly cover the top of the second hole segment 305, resulting in a better sealing effect. Moreover, when the battery is installed in the vehicle, it can prevent the explosion-proof plate 302 from shaking up and down randomly and generating noise during vehicle operation. When the high-pressure airflow inside the battery enters the second hole segment 305 from the bottom end and impacts the explosion-proof plate 302, the elastic element 307 elastically deforms, allowing the explosion-proof plate 302 to slide upward and release the cover over the second hole segment 305.

[0078] In some implementations, such as Figure 4 and Figure 5 As shown, the elastic element 307 includes a connecting portion 308 and an elastic sheet 309. The connecting portion 308 is connected to the hole wall of the first hole segment 304. For example, the connecting portion 308 can be integrally formed with the hole wall of the first hole segment 304, welded, or connected by screws. The elastic sheet 309 is connected to the connecting portion 308. For example, the elastic sheet 309 can be integrally formed with the connecting portion 308 or welded. The elastic sheet 309 extends from top to bottom along the axis close to the first hole segment 304. This configuration not only improves the elastic contact effect of the explosion-proof plate 302, thus improving the sealing performance of the explosion-proof plate 302, but also makes it easier for the elastic sheet 309 to deform elastically when the high-pressure airflow inside the battery enters the second hole segment 305 from the bottom end and impacts the explosion-proof plate 302, thus facilitating air permeability and improving the explosion-proof effect.

[0079] In some implementations, such as Figure 3 and Figure 4 As shown, multiple elastic elements 307 are arranged circumferentially along the first hole segment 304, and multiple connecting grooves 306 are arranged circumferentially along the first hole segment 304. The multiple elastic elements 307 not only provide better elastic contact with the explosion-proof plate 302, but also prevent the explosion-proof plate 302 from flipping during sliding. The multiple connecting grooves 306 allow for faster airflow, resulting in better air permeability and explosion-proof performance.

[0080] In some implementations, such as Figure 4 and Figure 5 As shown, the elastic element 307 and the connecting groove 306 are arranged in a staggered manner along the circumference of the first hole section 304. This arrangement can prevent the elastic element 307 from affecting the air permeability of the connecting groove 306.

[0081] In some implementations, such as Figure 4 and Figure 5 As shown, the cover 200 has a through mounting hole 206. The mounting base 301 includes a mounting part 310 and a stud 315. The mounting part 310 includes a mounting ring 311 and a convex ring 312. The mounting ring 311 is mounted on the upper end of the cover 200 by a fastener 313. The mounting ring 311 has a threaded hole 314. The convex ring 312 is located at the bottom end of the mounting ring 311 and is inserted into the mounting hole 206. A second hole section 305 is located on the convex ring 312. The diameter of the threaded hole 314 is larger than the diameter of the second hole section 305. The stud 315 is threadedly connected to the threaded hole 314. A first hole section 304 is located on the stud 315.

[0082] In this embodiment, during assembly, the protruding ring 312 is inserted into the mounting hole 206 of the cover 200, the mounting ring 311 is connected to the cover 200 by fasteners 313, the explosion-proof plate 302 is placed in the first hole section 304 of the stud 315, and the stud 315 is threaded into the threaded hole 314 of the mounting ring 311. The assembly is simple and convenient, which makes it easier to clean, maintain and replace.

[0083] In some implementations, such as Figure 4 and Figure 5 As shown, the top of the stud 315 protrudes beyond the top of the mounting ring 311. This design facilitates the rotation of the stud 315, thereby facilitating its installation and removal.

[0084] In some implementations, such as Figure 4 and Figure 5 As shown, the outer end of the bottom surface of the convex ring 312 is flush with the bottom surface of the cover 200, and the bottom surface of the convex ring 312 extends upward from the outside to the inside. With this configuration, the bottom surface of the convex ring 312 can guide the high-pressure gas inside the battery, making it easier for the high-pressure gas inside the battery to quickly enter the second hole section 305 of the convex ring 312.

[0085] In some implementations, such as Figure 4 and Figure 5 As shown, a sealing ring 316 is held between the bottom surface of the mounting ring 311 and the top surface of the cover 200. The sealing ring 316 reduces the amount of external water and dust that can enter the battery through the gap between the bottom surface of the mounting ring 311 and the top surface of the cover 200.

These additional beneficial effects will not be elaborated here.

[0088] This application also provides an electric two-wheeled vehicle, which includes the battery described above.

[0089] 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.
