[0038] In addition, the terms "first", "second" are only for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features.

[0039] As the background art shows, in the prior art, the skeleton oil seal includes a sealing body and a spring ring, the sealing body is sleeved on the rotating shaft, and the spring ring is embedded at the root of the sealing body. The spring ring applies a radial clamping force to make the sealing body tightly adhere to the surface of the rotating shaft, thereby achieving a sealing effect.

[0040] However, the spring ring may lose elasticity after long-term use, resulting in poor sealing effect and oil leakage. Moreover, the spring ring may be corroded, affecting its physical properties and causing loss of elasticity. The spring ring may also age in high temperature, high humidity or strong ultraviolet light, thereby affecting its elasticity and strength.

[0041] Based on this, the sealing structure and vehicle provided by the present application, the sealing structure is provided with a sealing member, a first detection member and a controller. The sealing member is used to be sleeved on a rotating member. The sealing member is provided with an overflow channel. The overflow channel is provided with a control valve. The overflow channel is connected with an external liquid supply member through the control valve. The first detection member can detect whether the sealing member leaks oil. The first detection member and the control valve are both in communication connection with the controller. When the first detection member detects that the sealing member leaks oil, the first detection member transmits the signal of oil leakage to the controller. The controller controls the control valve to open, so that the external liquid supply member injects liquid into the overflow channel. The static pressure of the liquid provides a holding force for the sealing member, so that the sealing member adheres to the surface of the rotating member under the static pressure of the liquid, thereby improving the sealing effect of the sealing member and reducing the possibility of oil leakage.

[0042] In order to make the purposes, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described in more detail below with reference to the drawings in the preferred embodiments of the present application. In the drawings, the same or similar notations represent the same or similar components or components with the same or similar functions throughout. The described embodiments are part of the embodiments of the present application, rather than all the embodiments. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0043] Referring to Figure 1 and Figure 2 In a first aspect, the sealing structure provided by the present application comprises a sealing member 100, a first detection member 200 and a controller. The sealing member 100 is arranged on a rotating member 10. The sealing member 100 is provided with a flow passage 110. The flow passage 110 is provided with a control valve 120. The flow passage 110 is connected to an external liquid supply member through the control valve 120.

[0044] The first detection member 200 is used to detect whether the sealing member 100 leaks oil.

[0045] The first detection member 200 and the control valve 120 are both in communication connection with the controller. When the sealing member 100 leaks oil, the controller controls the control valve 120 to open, so that the external liquid supply member injects liquid into the flow passage 110, so that the sealing member 100 is attached to the surface of the rotating member 10 under the static pressure of the liquid.

[0046] It should be noted that the rotating member 10 can be a rotating shaft of an engine or a transmission of a vehicle, or other rotating components, and the embodiments of the present application do not make too many limitations.

[0047] The sealing member 100 is arranged on the rotating member 10 to achieve a sealing effect and prevent lubricating oil from leaking from around the rotating member 10.

[0048] Exemplarily, the sealing member 100 can be made of an oil-resistant and wear-resistant elastic material, such as fluororubber, nitrile rubber, etc. These materials can withstand high-speed movement and high-temperature environment of the rotating member 10. Other materials can also be used, and the embodiments of the present application do not make too many limitations.

[0049] It should be noted that the design of the sealing member 100 can consider its close fit with the rotating member 10 to provide good sealing effect. Exemplarily, the sealing member 100 can adopt a lip-shaped design to enhance the sealing performance.

[0050] By setting the overflow passage 110 in the seal 100 and injecting liquid in the overflow passage 110, the seal 100 is provided with a holding force by the static pressure of the liquid, so that the sealing performance of the seal 100 can be dynamically compensated, the sealing effect of the seal 100 is enhanced, and the possibility of oil leakage is reduced. By using the static pressure of the liquid to provide the holding force for the seal 100, the error between the seal 100 and the rotating part 10 can also be automatically adapted.

[0051] It should be noted that the overflow passage 110 can pass through the inside of the seal 100, so that the liquid can flow rapidly and effectively. In specific implementation, the diameter and layout of the overflow passage 110 can be designed according to specific needs.

[0052] By setting the first detection part 200, the sealing state of the seal 100 can be detected in real time, so that the oil leakage of the seal 100 can be accurately detected. Moreover, the first detection part 200 is in communication connection with the controller, so that the system can automatically respond to the detected oil leakage and quickly take remedial measures.

[0053] Exemplarily, the first detection part 200 can be a sensor or other detection device, and the embodiments of the present application do not make too many limitations thereon.

[0054] In some embodiments, a certain liquid can be first injected in the overflow passage 110 of the seal 100, and the initial holding force of the seal 100 is provided by the static pressure of the liquid; when the first detection part 200 detects that the seal 100 leaks oil, liquid is injected into the overflow passage 110 again, so as to further improve the fastening force and thus the sealing effect of the seal 100.

[0055] In some embodiments, a certain fastening force can be provided by the interference fit between the seal 100 and the rotating part 10; when the first detection part 200 detects that the seal 100 leaks oil, liquid is injected into the overflow passage 110 again, so as to further improve the sealing effect of the seal 100.

[0056] In some embodiments, a spring ring can be sleeved at the root of the seal 100, and the initial clamping force is provided by the spring ring; when the first detection part 200 detects that the seal 100 leaks oil, liquid is injected into the overflow passage 110 again, so as to further improve the sealing effect of the seal 100.

[0057] The control valve 120 is used to control the communication state between the external liquid supply part and the overflow passage 110, and the control valve 120 is in communication connection with the controller. When oil leakage is detected, the controller instructs the control valve 120 to open, so that the external liquid supply part injects liquid into the overflow passage 110. This dynamic liquid injection mode can rapidly increase the pressure between the seal 100 and the rotating part 10, so as to enhance the sealing effect of the seal 100.

[0058] Exemplarily, the control valve 120 can be a proportional valve, a solenoid valve or other types of automatic valves, and the embodiments of the present application do not make too many limitations in this regard.

[0059] It should be further pointed out that the liquid injected into the overflow passage 110 by the external liquid supply can be oil or other liquid, and the embodiments of the present application do not make too many limitations in this regard.

[0060] It can be understood that, in the prior art, the spring ring of the skeleton oil seal can be elastically weakened after long-term use, resulting in poor sealing effect and oil leakage. The sealing structure and the vehicle provided by the present application, the sealing structure is provided with a sealing member 100, a first detection member 200 and a controller. The sealing member 100 is sleeved on the rotating member 10, and the sealing member 100 is provided with an overflow passage 110. The overflow passage 110 is connected with the external liquid supply through the control valve 120. The first detection member 200 can detect whether the sealing member 100 leaks oil. The first detection member 200 and the control valve 120 are both in communication connection with the controller. When the first detection member 200 detects that the sealing member 100 leaks oil, the first detection member 200 transmits the signal of oil leakage to the controller, and the controller controls the control valve 120 to open, so that the external liquid supply injects liquid into the overflow passage 110. The static pressure of the liquid provides a holding force for the sealing member 100, so that the sealing member 100 is attached to the surface of the rotating member 10 under the static pressure of the liquid, thereby improving the sealing effect of the sealing member 100 and reducing the possibility of oil leakage.

[0061] In some embodiments, referring to Figure 2 It is shown that the first detection member 200 is a fluorescent sensor.

[0062] It should be pointed out that the fluorescent sensor has high sensitivity and high accuracy, and can detect small oil leakage, thereby improving the reliability of the detection result.

[0063] The fluorescent sensor is in communication connection with the controller. The fluorescent sensor can detect the leakage of oil in real time, provide rapid response, and trigger the controller to issue corresponding remedial measures.

[0064] In some embodiments, referring to Figure 2 It is shown that the sealing member 100 is provided with a first sealing portion 130. The first sealing portion 130 is used to isolate the oil and the external dust. The first detection member 200 is arranged on the outer wall of the first sealing portion 130.

[0065] Specifically, the first sealing portion 130 can prevent internal oil leakage to the external environment, and at the same time prevent external dust and pollutants from entering the internal mechanical equipment, which is helpful to maintain the cleanliness and lubrication effect of the internal mechanical equipment.

[0066] It can be understood that the first detection member 200 (such as a fluorescence sensor) is arranged on the outer wall of the first sealing part 130, which can monitor the state of the first sealing part 130 in real time and quickly detect the oil leakage phenomenon.

[0067] In some embodiments, referring to Figure 2 As shown, the sealing member 100 is further provided with a second sealing part 140, which is located on the side of the first sealing part 130 away from the first detection member 200, and the second sealing part 140 is used to isolate the oil.

[0068] It should be noted that the second sealing part 140 provides an additional sealing layer, further enhancing the sealing effect of the sealing member 100, and can effectively reduce the risk of oil leakage.

[0069] In some embodiments, referring to Figure 2 and Figure 3 As shown, the flow passage 110 is annular.

[0070] It should be noted that the annular flow passage 110 can uniformly distribute the liquid within the entire sealing member 100 to uniformly apply static pressure on the entire contact surface of the sealing member 100. In this way, uniform pressure distribution helps to avoid the situation of excessive or insufficient local pressure, thereby improving the sealing effect.

[0071] The annular flow passage 110 can automatically adapt to pressure changes, maintaining good sealing effect even under dynamic conditions such as temperature changes or mechanical vibrations.

[0072] In some embodiments, referring to Figure 2 and Figure 3 As shown, the flow passage 110 is concentrically arranged with the sealing member 100.

[0073] It should be noted that the concentric arrangement of the flow passage 110 and the sealing member 100 enables the pressure of the liquid in the flow passage 110 to be uniformly transmitted to the sealing member 100, thereby exerting consistent holding force on the rotating member 10 and improving the sealing effect.

[0074] The concentric design provides structural symmetry, making the sealing member 100 more balanced when under stress, reducing the risk of deformation or failure caused by uneven stress. Under rotating or vibrating conditions, the concentric structure helps to maintain the stability of the system and reduce the displacement or loosening of the sealing member 100.

[0075] In some embodiments, referring to Figure 2 As shown, the sealing member 100 is further provided with a connecting pipe member 150, which connects the flow passage 110 and the control valve 120.

[0076] Specifically, the connecting pipe 150 provides a dedicated path for transmitting the liquid from the control valve 120 to the flow passage 110, so that the liquid can quickly and effectively reach the seal 100, enhancing the sealing effect.

[0077] In some embodiments, referring to Figure 2 As shown, the sealing structure further comprises a second detection member, which is arranged in the flow passage 110 and is used to detect the pressure value of the liquid injected into the flow passage 110.

[0078] The second detection member is in communication connection with the controller, and the controller controls the control valve 120 to be closed when the pressure value of the liquid is greater than a preset pressure, so as to stop the external liquid supply member from injecting liquid into the flow passage 110.

[0079] Specifically, by arranging the second detection member to monitor the liquid pressure in the flow passage 110 in real time, the situation of excessively high pressure can be prevented, the seal 100 can be prevented from being damaged or the system from malfunctioning, and the safety is improved.

[0080] When the second detection member detects that the pressure value exceeds the preset pressure, the second detection member transmits a pressure signal to the controller, and the controller controls the control valve 120 to be closed to stop the liquid injection into the flow passage 110, so that the need for manual intervention is reduced, and the response speed and efficiency of the system are improved.

[0081] It should be noted that the second detection member and the control valve 120 can be a pressure sensor and a solenoid valve, respectively; the second detection member and the control valve 120 can also be integrated, such as a proportional valve, which simultaneously realizes the pressure detection and flow control of the liquid, and the present application does not make too many limitations on this.

[0082] It should be further noted that the pressure of the liquid can be automatically adjusted by the proportional valve, and when the seal 100 and the rotating member 10 are worn or the system pressure is increased, the proportional valve can change the output pressure. Artificial intelligence (AI), big data, and camera sensors can also be used to realize automatic control of the system. The entire system adopts closed-loop control and can realize automatic monitoring, automatic adjustment, and automatic adaptation.

[0083] In some embodiments, referring to Figure 2 and Figure 3 As shown, the sealing structure further comprises a support member 300 embedded in the seal 100.

[0084] The support member 300 provides additional mechanical support, enhances the structural stability of the seal 100, prevents the seal 100 from deforming under high pressure or high temperature conditions, and helps to maintain the shape and function of the seal 100.

[0085] The support 300 can also help the seal 100 to maintain uniform distribution when under stress, reducing local stress concentration, thereby improving overall sealing performance.

[0086] In a second aspect, the application further provides a vehicle, comprising a vehicle body and a sealing structure arranged on the vehicle body.

[0087] The specific structure and working mode of the sealing structure are described in detail in the above embodiments, and will not be repeated here.

[0088] As can be understood by those skilled in the art, the sealing structure and the vehicle provided by the application, the sealing structure is provided with a seal 100, a first detection member 200 and a controller, the seal 100 is arranged on the rotating member 10, the seal 100 is provided with an overflow passage 110, the overflow passage 110 is provided with a control valve 120, and the overflow passage 110 is connected with an external liquid supply member through the control valve 120. The first detection member 200 can detect whether the seal 100 leaks oil. The first detection member 200 and the control valve 120 are both in communication connection with the controller. When the first detection member 200 detects that the seal 100 leaks oil, the first detection member 200 transmits the signal of oil leakage to the controller, and the controller controls the control valve 120 to open, so that the external liquid supply member injects liquid into the overflow passage 110. The static pressure of the liquid provides a holding force for the seal 100, so that the seal 100 is attached to the surface of the rotating member 10 under the static pressure of the liquid, thereby improving the sealing effect of the seal 100 and reducing the possibility of oil leakage.
