The tire pressure sensor is scrapped as a whole, resulting in a waste of costs and resources. In addition, the process of replacing the tire pressure sensor requires repeatedly peeling off the rubber skin on the outside of the wheel hub, disassembling the tire pressure sensor, installing a new tire pressure sensor, and then adjusting the wheel dynamic balance and matching the tire pressure sensor. The entire process is relatively cumbersome, increasing the replacement cost. Utility Model Content

[0026] Reference below Figure 1-Figure 4 A tire pressure sensor 100 according to an embodiment of the first aspect of the present utility model is described.

[0027] like Figure 1-Figure 4 As shown, the tire pressure sensor 100 according to the first embodiment of the utility model includes a housing 1 and a conductive device 2.

[0028] Specifically, a sensor module 11 and a battery module 12 are arranged in the housing 1, and the sensor module 11 and the battery module 12 are arranged at intervals along the length direction of the housing 1. The positive electrode of the battery module 12 is connected to a positive electrode connection line 121, and the negative electrode of the battery module 12 is connected to a negative electrode connection line 122. The conductive device 2 is arranged on the outside of the housing 1, and the positive electrode connection line 121 and the negative electrode connection line 122 are both electrically connected to the conductive device 2. When the battery module 12 is charged, the conductive device 2 is suitable for being electrically connected to an external charging device.

[0029] For example, in Figure 1-Figure 4 In the example, the sensor module 11 and the battery module 12 are respectively located in the length direction of the housing 1 (for example, Figure 1 The battery module 12 can supply power to the sensor module 11 so that the sensor module 11 can work normally. The conductive device 2 is located in the height direction of the housing 1 (for example, Figure 1 The conductive device 2 is connected to one side of the housing 1 in the thickness direction (for example, Figure 4 The positive electrode connection line 121 and the negative electrode connection line 122 are led out from the battery module 12 and extend upward so that the positive electrode connection line 121 and the negative electrode connection line 122 can be connected to the conductive device 2. After the positive electrode connection line 121 and the negative electrode connection line 122 are electrically connected to the conductive device 2, when the conductive device 2 is connected to an external charging device, the conductive device 2 can transfer the current transmitted from the external charging device to the positive electrode connection line 121 and the negative electrode connection line 122, so that the battery module 12 can receive the current transmitted from the external charging device, thereby charging the battery module 12.

[0030] In a traditional tire pressure sensor, the battery module 12 has a lifespan of about 3-5 years. When the battery module 12 runs out of power, the sensor module 11 still functions properly. However, due to the structure of the tire pressure sensor, the battery module 12 cannot be charged. The entire tire pressure sensor needs to be replaced with a battery module 12 with sufficient power. The tire pressure sensor is scrapped as a whole, resulting in a waste of costs and resources. The process of replacing the tire pressure sensor requires repeatedly peeling off the rubber skin on the outside of the wheel hub, disassembling the tire pressure sensor, installing a new tire pressure sensor, and adjusting the wheel dynamic balance to match the tire pressure sensor. The entire process is cumbersome and increases the replacement cost.

[0031] In the present application, the positive electrode of the battery module 12 is connected to the positive electrode connection line 121, and the negative electrode of the battery module 12 is connected to the negative electrode connection line 122, so that the external charging device can be connected to the positive electrode connection line 121 and the negative electrode connection line 122 through the conductive device 2. When the battery module 12 of the tire pressure sensor 100 is exhausted, the battery module 12 can be charged, so that the battery module 12 can continue to supply power to the sensor module 11, so that the sensor module 11 can be used normally. Such a setting can extend the service life of the tire pressure sensor 100, and there is no need to repeatedly replace the tire pressure sensor 100 in the wheel. It also reduces the operations of repeatedly removing the tire, replacing the tire pressure sensor 100, wheel dynamic balancing, and matching the tire pressure sensor 100, reducing the cost of using the vehicle and eliminating resource waste.

[0032] According to the tire pressure sensor 100 of the embodiment of the utility model, the positive electrode of the battery module 12 is connected to the positive electrode connection line 121, and the negative electrode of the battery module 12 is connected to the negative electrode connection line 122, so that the external charging device can be connected to the positive electrode connection line 121 and the negative electrode connection line 122 through the conductive device 2. Therefore, compared with the traditional tire pressure sensor, the service life of the tire pressure sensor 100 is extended, the tire pressure sensor 100 in the wheel does not need to be replaced repeatedly, and the operations required when replacing the tire pressure sensor 100 are also reduced, thereby reducing the use cost of the vehicle and eliminating resource waste.

[0033] According to some embodiments of the present invention, the conductive device 2 includes a conductive housing 21 , a conductive rod 22 and a conductive elastic member 23 .

[0034] Specifically, the conductive shell 21 has a housing cavity 211, and the conductive shell 21 is electrically connected to the negative electrode connection line 122. The conductive rod 22 is disposed in the housing cavity 211, and the conductive rod 22 is spaced apart from the inner wall of the housing cavity 211. The conductive elastic member 23 is disposed in the housing cavity 211, and the conductive elastic member 23 is spaced apart from the inner wall of the housing cavity 211, one end of the conductive elastic member 23 is electrically connected to the positive electrode connection line 121, and the other end of the conductive elastic member 23 is electrically connected to the conductive rod 22.

[0035] Reference Figure 1 The conductive rod 22 is disposed at one end of the accommodating cavity 211 away from the housing 1, and the conductive rod 22 is disposed along the length direction of the conductive housing 21 (for example, Figure 1 The conductive elastic member 23 is arranged in the accommodating cavity 211 and does not contact the inner wall of the accommodating cavity 211, and the conductive elastic member 23 also extends along the length direction of the conductive shell 21. One end of the conductive elastic member 23 is electrically connected to the conductive rod 22, so that current can pass between the conductive elastic member 23 and the conductive rod 22. One end of the conductive elastic member 23 away from the conductive rod 22 is electrically connected to the positive electrode connecting line 121, so that current can pass between the conductive elastic member 23 and the positive electrode connecting line 121. Among them, the conductive elastic member 23 can be a spring.

[0036] With such arrangement, when the external charging device is electrically connected to the conductive device 2, the conductive shell 21 connects the negative pole of the battery module 12 to the external charging device, and the conductive elastic member 23 connects the positive pole of the battery module 12 to the external charging device, so that the external charging device can charge the battery module 12. After the battery module 12 is fully charged, the battery module 12 can continue to supply power to the sensor module 11, thereby ensuring that the sensor module 11 can continue to work normally, thereby extending the service life of the tire pressure sensor 100.

[0037] Furthermore, one side of the conductive shell 21 away from the shell 1 is open, and the conductive device 2 further comprises a cover 24 , which is detachably disposed on the open side of the conductive shell 21 . When the battery module 12 is charged, the cover 24 is removed to expose the conductive rod 22 .

[0038] like Figure 1-Figure 4 As shown, the cover 24 is disposed on the side of the conductive shell 21 away from the housing 1 to close or open the accommodating cavity 211. When the wheel is in normal use, the cover 24 isolates the positive electrode connection line 121 and the negative electrode connection line 122 from the outside world, and isolates the inside of the wheel from the outside world.

[0039] When the battery module 12 needs to be charged, the cover 24 is removed to electrically connect the external charging device to the conductive shell 21 and the conductive rod 22. As a result, the conductive shell 21 and the conductive rod 22 can transmit current to the positive connecting line 121 and the negative connecting line 122. The current reaches the positive and negative electrodes of the battery module 12 along the positive connecting line 121 and the negative connecting line 122, so that the battery module 12 can start charging. The tire pressure sensor 100 is rechargeable, which extends the life of the tire pressure sensor 100 and reduces tire wear.

[0040] Furthermore, the cover 24 and the conductive housing 21 are threadedly connected. Figure 1-Figure 4 Through the threaded connection, the sealing effect of the cover body 24 on the accommodating cavity 211 of the conductive shell 21 can be strengthened, and the cover body 24 can be easily installed and disassembled, which is easy to operate and convenient for users to operate, thereby improving operating efficiency.

[0041] According to some embodiments of the present invention, the outer side of the conductive rod 22 is provided with a first insulating member 25, and the outer side of the conductive elastic member 23 is provided with a second insulating member 26. Figure 1-Figure 2 In the example, the first insulating member 25 and the second insulating member 26 are arranged at intervals along the length direction of the conductive shell 21, and the first insulating member 25 is arranged at the end of the accommodating cavity 211 away from the shell 1. In this way, the electrical connection between the conductive rod 22 and the conductive elastic member 23 and the conductive shell 21 can be disconnected, so as to prevent the conductive rod 22 and the conductive elastic member 23 from forming a loop through the conductive shell 21, thereby avoiding a short circuit and affecting the charging of the battery module 12, thereby improving the safety of the battery module 12 and the conductive device 2.

[0042] According to some embodiments of the present invention, the conductive device 2 further comprises a protective sleeve 27, which is disposed on the outer periphery of the conductive shell 21, the protective sleeve 27 is threadedly connected to the conductive shell 21, and the protective sleeve 27 and the cover body 24 are spaced apart along the axial direction of the conductive shell 21. Figure 1-Figure 3As shown, the protective cover 27 is arranged in the middle of the conductive shell 21. The protective cover 27 is threadedly connected to the conductive shell 21, which facilitates the installation of the protective cover 27, reduces the friction between the protective cover 27 and the conductive shell 21, and avoids the wear of the conductive shell 21, thereby improving the service life of the conductive shell 21. When the battery module 12 needs to be charged, when the cover 24 is removed, the operator can hold the protective cover 27 with one hand, remove the cover 24 with the other hand, and then connect the external charging device to the conductive device 2, which can prevent the operator from electric shock and has a good protective effect on the operator.

[0043] According to some embodiments of the present invention, referring to Figure 4 The conductive device 2 is disposed between the sensor module 11 and the battery module 12 in the length direction of the housing 1. This arrangement facilitates connecting the conductive device 2 to the housing 1, and also facilitates connecting the positive electrode connection line 121 and the negative electrode connection line 122 to the conductive device 2, and maintains the balance of the tire pressure sensor 100.

[0044] It should be noted that the conductive device 2 can also connect the outside with the inside of the wheel, that is, the wheel can be inflated through the conductive device 2. Specifically, after opening the cover 24, the inflator is connected to the conductive device 2, so that the inflator can transfer gas into the wheel. After the wheel is inflated, the inflator is removed and the cover 24 is installed on the conductive shell 21 to cut off the connection between the inside of the wheel and the outside. At the same time, when the air pressure inside the wheel changes, the conductive elastic member 23 can bear the load and undergo elastic deformation to prevent the pressure inside the wheel from being too high and causing danger.

[0045] The wheel (not shown) according to the embodiment of the second aspect of the utility model comprises the tire pressure sensor 100 according to the embodiment of the first aspect of the utility model.

[0046] According to the wheel of the embodiment of the utility model, by adopting the above-mentioned tire pressure sensor 100, the number of times the tire pressure sensor 100 is replaced can be reduced, and repeated tire removal, sensor replacement, tire dynamic balancing, sensor matching and other operations due to the exhaustion of the battery module 12 of the tire pressure sensor 100 are eliminated, thereby extending the service life of the wheel and reducing resource waste.

[0047] A vehicle (not shown) according to an embodiment of the third aspect of the utility model comprises a wheel according to an embodiment of the second aspect of the utility model.

[0048] According to the vehicle of the embodiment of the utility model, by adopting the above-mentioned wheel, the cost of using the vehicle and the waste of resources are reduced, and the tire pressure sensor 100 does not need to be frequently replaced, thereby improving the user experience.

[0049] Other structures and operations of the vehicle according to the embodiment of the utility model are known to ordinary technicians in the field and will not be described in detail here.
