Description

Technical Field

[0001] The present application belongs to the field of sensor technology, and specifically, the present application relates to a sensor, a tire and a vehicle. Background Art

[0002] With the improvement of living standards, cars have become a common means of transportation. When driving on complex roads, car tires are easily scratched or punctured or even burst, which may lead to the risk of vehicle rollover, thus affecting the personal safety of drivers and passengers. In order to prevent car rollover caused by tire blowout, a tire-proof device is usually installed on the car. Activating the tire-proof device can keep the car with a tire blowout balanced, thereby ensuring driving safety.

[0003] When the tire burst device is activated, a sensor that can monitor whether the tire of the car is leaking rapidly is usually needed to detect it in real time, and transmit the rapid leakage signal detected to the tire burst device in time to activate it. However, the current tire burst sensor usually fills gas into the built-in metal diaphragm box separately, and uses the volume change to link the switch to control the start of the tire burst device, which makes the sensor structure complex and the production cost high.

[0039] Reference Figures 1 to 5 An embodiment of the present application provides a sensor that can be used in a vehicle tire and can detect tire pressure changes, such as tire blowout detection, thereby ensuring the driving safety of the vehicle.

[0040] like Figure 1 and Figure 2 As shown, the sensor comprises:

[0041] A first shell 1 and a second shell 2, wherein the first shell 1 and the second shell 2 enclose a receiving space, and a first through hole 11 is formed on the first shell 1;

[0042] The elastic member 3, at least part of which is located in the accommodating space and divides the accommodating space into a first accommodating space 12 and a second accommodating space 13, and a second through hole 31 is provided on the elastic member 3, the second through hole 31 connects the first accommodating space 12 and the second accommodating space 13, and the second through hole 31 is connected to the outside through the first through hole 11.

[0043] like Figure 1 and Figure 2 As shown, the first shell 1 and the second shell 2 can be an upper shell and a base respectively, and a receiving space is formed between the first shell 1 and the second shell 2, so that other structures of the sensor can be accommodated and protected by the receiving space, thereby improving the detection reliability of the sensor.

[0044] like Figure 3 and Figure 4 As shown, a mounting post 14 may be provided on one of the first shell 1 and the second shell 2, and an assembly hole 24 adapted to the mounting post 14 may be provided on the other of the first shell 1 and the second shell 2, and the first shell 1 and the second shell 2 are connected by the matching of the mounting post 14 and the assembly hole 24. In addition, a receiving groove may be provided on the first shell 1 and the second shell 2, respectively, so that the first shell 1 and the second shell 2 can be buckled and combined to form an accommodating space.

[0045] like Figure 1 and Figure 2As shown, at least part of the elastic member 3 is arranged in the accommodating space, and the elastic member 3 can divide the accommodating space into a first accommodating space 12 and a second accommodating space 13. The first accommodating space 12 is formed between the elastic member 3 and the first shell 1, and the second accommodating space 13 is formed between the elastic member 3 and the second shell 2, that is, the two sides of the elastic member 3 are respectively located in the two accommodating spaces, so that the elastic member 3 can be elastically deformed under the drive of the pressure difference between the two accommodating spaces, and the sensor has a simple and reliable structure and low production cost.

[0046] Specifically, the elastic member 3 is provided with a second through hole 31, through which the first accommodation space 12 and the second accommodation space 13 on both sides of the elastic member 3 can be connected. Moreover, the second through hole 31 is connected to the outside through the first through hole 11, that is, the second accommodation space 13 can be connected to the outside through the second through hole 31, the first accommodation space 12 and the first through hole 11 in sequence, so that the pressure in the second accommodation space 13 can be consistent with the outside pressure.

[0047] That is, the second through hole 31 is a through hole on the elastic member 3, so that the accommodation spaces on both sides of the elastic member 3 are connected only through the second through hole 31, rather than directly connected, so that the resistance of the gas flowing into and out of the second accommodation space 13 can be strengthened. With this arrangement, the first accommodation space 12 can be directly connected to the outside world through the first through hole 11, while the second accommodation space 13 needs to pass through the second through hole 31, the first accommodation space 12 and the first through hole 11 in sequence to be connected to the outside world. When the external pressure changes, the gas path formed by the second through hole 31, the first accommodation space 12 and the first through hole 11 can delay the pressure change in the second accommodation space 13 to a certain extent, so that the pressure difference on both sides of the elastic member 3 can be maintained for a certain period of time, and then the elastic member 3 can be elastically deformed under the drive of the pressure difference and contact with the blocking structure on the shell and form a response.

[0048] For example, when the sensor is used in a vehicle tire, since the second through hole 31 can be connected to the outside through the first through hole 11, the pressure in the second accommodating space 13 can be kept consistent with the pressure in the tire during normal operation. When an abnormal situation such as a tire blowout occurs, the pressure in the tire will drop rapidly, that is, the pressure in the first accommodating space 12 will drop rapidly, and the air path formed by the second through hole 31, the first accommodating space 12 and the first through hole 11 allows the pressure in the second accommodating space 13 to maintain a relatively high pressure for a certain period of time, and the pressure difference can drive the elastic member 3 to deform toward the first shell 1 until it reliably contacts the baffle 4 or other blocking structures on the first shell 1 and triggers the vehicle body electronic stability system, that is, a tire blowout warning is issued, thereby ensuring the driving safety of the vehicle.

[0049] Among them, the opening of the second through hole 31 on the elastic member 3 not only connects the second accommodating space 13 with the outside world, but also delays the pressure change in the second accommodating space 13 when the external pressure changes, so that the elastic member 3 can be elastically deformed under the driving force of the pressure difference between the accommodating spaces on both sides, thereby ensuring the contact time between the elastic member 3 and the baffle 4 or other blocking structures, and improving the detection reliability of the sensor.

[0050] Optionally, a size of the second through hole 31 is smaller than a size of the first through hole 11 .

[0051] Specifically, in the embodiment of the utility model, the size of the second through hole 31 on the elastic member 3 is smaller than the size of the first through hole 11 on the first shell 1, that is, the size of the opening on the elastic member 3 is smaller, which can connect the second accommodating space 13 with the outside world while delaying the pressure change in the second accommodating space 13 when the external pressure changes, so that the elastic member 3 can be elastically deformed and contacted with the baffle 4 under the drive of the pressure difference between the accommodating spaces on both sides, thereby ensuring the contact time between the elastic member 3 and the baffle 4 and improving the detection reliability of the sensor.

[0052] Optionally, the second through hole 31 is a circular hole, and the diameter of the circular hole is less than 0.2 mm.

[0053] like Figure 5 As shown, in the embodiment of the utility model, the second through hole 31 is arranged as a circular hole, that is, a circular hole is opened on the elastic member 3 to connect the accommodating spaces on both sides. The circular hole can facilitate the opening of the second through hole 31 on the elastic member 3, thereby reducing the processing difficulty of the sensor, thereby improving the processing efficiency of the sensor.

[0054] In addition, the diameter of the circular hole is set to be less than 0.2 mm, that is, the second through hole 31 is controlled to be a small-sized hole. While the second through hole 31 is used to connect the accommodating spaces on both sides, the pressure change in the second accommodating space 13 when the external pressure changes can be delayed, so that the elastic member 3 can be elastically deformed under the drive of the pressure difference between the accommodating spaces on both sides, thereby ensuring the contact time between the elastic member 3 and the baffle 4 or other blocking structures, thereby improving the detection reliability of the sensor.

[0055] like Figure 5 As shown, in one embodiment, the elastic member 3 may include a central deformation portion and an annular fixing portion, the central deformation portion is integrally connected to the annular fixing portion, the second through hole 31 is provided on the central deformation portion, and the annular fixing portion is used to form a fixation with the mounting flange on the second shell 2 to achieve the installation of the elastic member 3.

[0056] Optionally, the first shell 1 has a first accommodating groove, the second shell 2 has a second accommodating groove, the first accommodating space 12 is formed between the elastic member 3 and the first accommodating groove, the second accommodating space 13 is formed between the elastic member 3 and the second accommodating groove, and the first through hole 11 is connected to the second accommodating space 13 through the first accommodating space 12 and the second through hole 31.

[0057] like Figure 1 and Figure 2 As shown, the first housing 1 is provided with a first receiving groove, and the second housing 2 is provided with a second receiving groove, and the first receiving groove and the second receiving groove form a receiving space inside the first housing 1 and the second housing 2. The elastic member 3 is located on a side of the second housing 2 close to the first housing 1, and the first receiving space 12 and the second receiving space 13 are respectively formed on both sides of the elastic member 3, so that the elastic member 3 can be elastically deformed under the driving force of the pressure difference between the two receiving spaces.

[0058] Optionally, a first seal 21 and a second seal 23 are provided in the second receiving groove, and the elastic member 3, the first seal 21 and the second seal 23 form the second receiving space 13, and the elastic member 3 is against the first seal 21. The setting of the first seal 21 and the second seal 23 can enhance the sealing effect of the second receiving space 13, thereby improving the detection reliability of the sensor.

[0059] Optionally, a first seal 21, a third seal 22 and a second seal 23 are sequentially provided in the second accommodating groove, the third seal 22 is connected between the first seal 21 and the second seal 23, the elastic member 3, the first seal 21, the third seal 22 and the second seal 23 form the second accommodating space 13, and the elastic member 3 is against the first seal 21.

[0060] like Figure 2 As shown, the first seal 21, the third seal 22 and the second seal 23 can be sequentially arranged in the second receiving groove, the second seal 23 is located at the bottom, the first seal 21 is located at the top, and the third seal 22 is connected between the first seal 21 and the second seal 23, so as to improve the sealing performance of the second receiving space 13 surrounded by the elastic member 3, the first seal 21, the third seal 22 and the second seal 23. The second receiving space 13 is connected to the outside through the second through hole 31 and the first through hole 11, and it is also convenient to realize the sealing process.

[0061] The first sealing member 21 , the second sealing member 23 and the third sealing member 22 may be made of conventional sealing rubber, sealing silicone and other materials.

[0062] In addition, the elastic member 3 is arranged to abut against the first sealing member 21, that is, the contact portion of the elastic member 3 and the first sealing member 21 forms a relatively tight fit, thereby ensuring a good sealing effect of the second accommodating space 13 and reducing the risk of gas flowing out of the second accommodating space 13 through the gap.

[0063] Optionally, the first sealing member 21 is in a trumpet-shaped structure, and a small opening of the trumpet-shaped structure abuts against the elastic member 3 .

[0064] Specifically, the embodiment of the utility model sets a trumpet-shaped structure with a small opening against the elastic member 3, so as to reduce the opening size of the first sealing member 21, so as to facilitate the first sealing member 21 and the elastic member 3 to form a tight fit, thereby reducing the risk of gas flowing out of the second accommodation space 13 from the gap. It also improves the detection reliability of the sensor.

[0065] The large mouth of the trumpet-shaped structure is connected to the third sealing member 22, which also facilitates the implementation of the sealing process.

[0066] Optionally, a baffle 4 is further included, and the baffle 4 is arranged in the first accommodating groove. Along the height direction of the sensor, the projection of the baffle 4 partially overlaps with the projection of the elastic member 3.

[0067] like Figure 1 and Figure 2 As shown, a baffle 4 is provided on one side of the first shell 1 close to the second shell 2. When an abnormal situation such as a tire blowout occurs, the pressure in the tire will drop rapidly. The design of the second through hole 31 enables the pressure in the second accommodating space 13 to maintain a relatively high pressure for a certain period of time. The pressure difference can drive the elastic member 3 to deform toward the first shell 1 until it contacts the baffle 4 and triggers the vehicle body electronic stability system, that is, a tire blowout warning is issued, thereby ensuring the driving safety of the vehicle.

[0068] In addition, it is arranged that along the height direction of the sensor (i.e., the stacking direction of the first shell 1 and the second shell 2), the projection of the baffle 4 partially overlaps with the projection of the elastic member 3, so that the elastic member 3 can contact the baffle 4 under the drive of the pressure difference and trigger the vehicle body electronic stability system to realize the tire blowout warning.

[0069] Optionally, the elastic member 3 has a first electrical connection point, and the blocking piece 4 has a second electrical connection point, and when the elastic member 3 is in contact with the blocking piece 4, the first electrical connection point is electrically connected to the second electrical connection point.

[0070] Specifically, the embodiment of the utility model provides a first electrical connection point and a second electrical connection point on the elastic member 3 and the baffle 4, respectively. When the elastic member 3 contacts the baffle 4 driven by the pressure difference, the first electrical connection point and the second electrical connection point form an electrical connection and can trigger the vehicle body electronic stability system; when the pressure of the accommodating space on both sides of the elastic member 3 is basically the same or the pressure difference is small, the elastic member 3 is released from contact with the baffle 4, and the first electrical connection point and the second electrical connection point are electrically disconnected, thereby realizing the tire pressure change detection of the tire using the sensor.

[0071] In another embodiment, the elastic member 3 and the baffle 4 may be configured as a conductive structure, for example, made of conductive metal, so that the electrical connection between the elastic member 3 and the baffle 4 can be achieved.

[0072] Optionally, the embodiment of the utility model sets the first electrical connection point and the second electrical connection point to be relative to each other, so that when the elastic member 3 is in contact with the baffle 4, an electrical connection between the first electrical connection point and the second electrical connection point can be easily formed, thereby realizing the detection of external pressure changes.

[0073] Optionally, it further includes a PCB board 5, the second shell 2 is located on the PCB board 5, the first shell 1 is located on a side of the second shell 2 away from the PCB board 5, and the baffle 4 and the elastic member 3 are electrically connected to the PCB board 5 respectively.

[0074] like Figure 1 and Figure 2 As shown, the first shell 1 and the second shell 2 are respectively arranged on the PCB board 5, for example, they can be fixed on the PCB board 5 by means of a buckle 25, that is, the PCB board 5 can be used to support and fix the first shell 1 and the second shell 2, thereby improving the structural stability of the sensor. In addition, the baffle 4 and the elastic member 3 are respectively electrically connected to the PCB board 5, and when the elastic member 3 contacts the baffle 4 under the drive of the pressure difference, the first electrical connection point and the second electrical connection point form an electrical connection and form a signal transmission loop with the PCB board 5, so that the tire blowout warning signal can be transmitted to the PCB board 5 and the vehicle body electronic stability system can be quickly triggered.

[0075] Optionally, the elastic member 3 includes a first section and a second section, a first angle is formed between the first section and the second section, the first section is located on a side of the second shell 2 close to the first shell 1, the second section is connected to the PCB board 5, and the first electrical connection point is located on the first section.

[0076] like Figure 1 , Figure 2 and Figure 5As shown, the first angle can be 90 degrees, that is, the elastic member 3 is vertically bent into a first section and a second section, the first section is located on the second housing 2 and opposite to the baffle 4, and the second section extends into the PCB board 5 to fix the elastic member 3. According to the actual processing technology, the first angle can also be other suitable angles.

[0077] Optionally, the baffle 4 includes a third section and a fourth section, a second angle is formed between the third section and the fourth section, the third section is located on a side of the first shell 1 close to the second shell 2, the fourth section is connected to the PCB board 5, and the second electrical connection point is located on the third section.

[0078] The second angle may be 90 degrees, that is, the baffle 4 is vertically bent into a third section and a fourth section, the third section is located on the first housing 1 and opposite to the elastic member 3, and the fourth section extends into the PCB board 5 to fix the baffle 4. According to the actual processing technology, the second angle may also be other suitable angles.

[0079] An embodiment of the present application further provides a tire, comprising the above-mentioned sensor, wherein the sensor is located inside the tire.

[0080] An embodiment of the present application also provides a vehicle, including a vehicle body and the above-mentioned tire.

[0081] During normal driving of the vehicle, since the second through hole 31 is connected to the outside through the first through hole 11, the pressure in the second accommodation space 13 can be kept consistent with the pressure in the tire. When an abnormal situation such as a tire blowout occurs, the pressure in the tire will drop rapidly, and the pressure in the connected first accommodation space 12 will also drop rapidly. The air path formed by the second through hole 31, the first accommodation space 12 and the first through hole 11 can delay the pressure change in the second accommodation space 13, so that the pressure in the second accommodation space 13 can maintain a relatively high pressure for a certain period of time. The pressure difference can drive the elastic member 3 to deform toward the first shell 1 until it contacts the baffle 4 on the first shell 1 and triggers the vehicle body electronic stability system, that is, a tire blowout warning is issued, thereby ensuring the driving safety of the vehicle.
