[0021] See also Figure 1 As shown, the present application proposes a driving shaft sealing system 100 for a vehicle. The driving shaft sealing system 100 for the vehicle includes a driving shaft universal joint 10, an intermediate shaft 20 and a sealing assembly 30. The driving shaft universal joint 10 includes a main body 11 and an annular wall 12 extending from one side of the main body 11; the intermediate shaft 20 passes through the annular wall 12 and is connected to the main body 11; the sealing assembly 30 includes a sealing member 31 and a clamping member 32, the sealing member 31 is arranged between the annular wall 12 and the intermediate shaft 20, and is used to seal the gap between the annular wall 12 and the intermediate shaft 20, and the clamping member 32 is arranged around the surface of the sealing member 31 to clamp the sealing member 31 to fit the intermediate shaft 20.

[0022] The main body 11 is the core part of the entire drive shaft universal joint 10, responsible for connection with other components, power transmission, etc. The annular wall 12 provides a structural basis for subsequent cooperation with the intermediate shaft 20 and the sealing assembly 30. The intermediate shaft 20 is used to connect and transmit power. After passing through the annular wall 12 of the drive shaft universal joint 10, it is connected to the main body 11. Through this connection method, the power is smoothly transmitted between the drive shaft universal joint 10 and the intermediate shaft 20, and it cooperates with the sealing assembly 30 to maintain the sealing and stability of the drive shaft sealing system 100 of the entire vehicle.

[0023] Specifically, a seal 31 is formed between the annular wall 12 and the intermediate shaft 20, one end of the seal 31 is connected to the annular wall 12, and the other end is connected to the intermediate shaft 20, so that a sealing treatment is formed for the gap between the two to build an anti-seepage defense line. A clamping member 32 is further provided, and the main function of the clamping member 32 is to apply a certain clamping force to the seal 31, so that the seal 31 can fit more closely on the intermediate shaft 20. Such a close fit further enhances the sealing effect, ensuring that during the operation of the drive shaft, even if it is affected by factors such as vibration and temperature changes, the seal 31 can always maintain a good sealing state to prevent any possible water seepage to the drive shaft.

[0024] The sealing member 31 may be a sealing rubber member or a sealing silicone member. Both rubber and silicone materials have good elasticity and flexibility, and can adapt to the slight deformation and displacement between the annular wall 12 and the intermediate shaft 20, thereby maintaining a tight sealing effect. Both materials have good corrosion resistance, wear resistance and high temperature resistance, which are conducive to adapting to various harsh environmental conditions.

[0025] The clamping member 32 includes a clamp and an elastic ring. The clamp is usually made of metal or plastic, and has two opposing clamping arms, which are connected together by bolts, nuts or other fasteners. When the clamping arms are tightened, pressure can be applied to the seal 31 to fix it in a desired position. The elastic ring is usually made of rubber, silicone or other elastic materials, has an annular structure, and has a certain elasticity and restoring force. When the elastic ring is installed around the seal 31, it will shrink due to its own elasticity so that the seal 31 fits tightly on the intermediate shaft 20.

[0026] See also Figure 1 As shown, in some embodiments, the seal 31 is an annular sealing sleeve, the diameter of the annular sealing sleeve increases from one end to the other end, and the end with a larger diameter is folded outward to form a docking portion 311; wherein, the end of the annular sealing sleeve with a smaller diameter is sleeved on the intermediate shaft 20, and the docking portion 311 is connected to the annular wall 12.

[0027] In this embodiment, the sealing member 31 is in the form of a sealing sleeve, which is convenient for sleeve connection on the intermediate shaft 20. The shape of the sealing sleeve is further designed, including a design of gradually increasing diameter and a butt joint 311 formed by folding outward, so that the sealing sleeve can fill the gap between the intermediate shaft 20 and the annular wall 12 and connect the sealing sleeve to the annular wall 12. In this way, the sealing member 31 can effectively achieve its sealing effect.

[0028] Specifically, the end of the annular sealing sleeve with a smaller diameter is provided with a clamping portion 312 and a fitting portion 313 in sequence toward the port thereof; the clamping portion 312 is used to set a clamping member 32, so that the clamping portion 312 is clamped on the intermediate shaft 20 through the clamping member 32; and the fitting portion 313 and the intermediate shaft 20 are in interference fit, so that the sealing member 31 is tightly attached to the intermediate shaft 20. This arrangement actually establishes two lines of defense against water seepage. Among them: The first part of the annular sealing sleeve with a smaller diameter is the hoop portion 312, which is arranged toward the port. The main function of the hoop portion 312 is to provide an area for setting the clamping member 32. The clamping member 32 clamps the hoop portion 312 (a part of the sealing member 31) on the intermediate shaft 20, thereby ensuring a tight fit between the hoop portion 312 and the intermediate shaft 20, which is a sealing line of defense. Following the hoop portion 312 is the fitting portion 313, which is an interference fit with the intermediate shaft 20. The interference fit means that the inner diameter of the fitting portion 313 is slightly smaller than the diameter of the intermediate shaft 20, so when the sealing sleeve is installed on the intermediate shaft 20, the fitting portion 313 will be compressed to a certain extent, so that it fits tightly on the intermediate shaft 20, thereby establishing another sealing line of defense. Because the fitting portion 313 is closer to the port of the sealing member 31, the cooperation between the fitting portion 313 and the intermediate shaft 20 is the first line of defense, and the cooperation between the clamping portion 312 and the intermediate shaft 20 is the second line of defense. The sealing and waterproof performance can be improved by setting two sealing lines of defense.

[0029] See also Figure 1 As shown, in some embodiments, the number of the clamping members 32 is multiple, wherein the provision of one clamping member 32 is to add a sealing defense line, and when multiple clamping members 32 are provided, the sealing and waterproofing effect can be greatly improved. Further, some of the clamping members 32 are provided corresponding to the fitting portion 313, so that the fitting portion 313 is further clamped on the intermediate shaft 20 on the basis of the fitting portion 313 being closely attached to the intermediate shaft 20, and the close attachment effect of the fitting portion 313 is strengthened, thereby achieving a higher sealing and waterproofing effect.

[0030] See also Figure 1 As shown, in some embodiments, the hoop portion 312 and the fitting portion 313 are annularly formed with a tightening hoop limiting groove 314 along their outer walls, and the butt joint of the hoop member 32 is arranged in the tightening hoop limiting groove 314 .

[0031] In this embodiment, the clamping limit groove 314 is an annular groove surrounding the outer wall of the sealing sleeve. The clamping member 32 is provided with a clear installation position through the groove. When the clamping member 32 is installed in the clamping limit groove 314, the clamping limit groove 314 can ensure that the sealing sleeve will not move axially along the intermediate shaft 20, thereby maintaining a stable position. In addition, through the cooperation between the clamping limit groove 314 and the clamping member 32, the contact pressure between the sealing sleeve and the intermediate shaft 20 can be further increased, thereby improving the waterproof sealing performance.

[0032] In some embodiments, the intermediate shaft 20 is provided with an annular sealing groove (not shown in the drawings) along its outer wall, and the sealing groove is connected to the clamping member 32 so that the sealing member 31 is pressed into the sealing groove under the clamping action of the clamping member 32.

[0033] In this embodiment, the main function of the sealing groove is to provide an area for receiving the sealing member 31 squeezed by the clamping member 32. It can be understood that when the clamping member 32 clamps the sealing member 31 on the intermediate shaft 20, the clamping member 32 will generate an inward pressure on the sealing member 31, pressing the sealing member 31 into the sealing groove. In this way, a close contact is formed between the sealing member 31 and the sealing groove, which helps to enhance its sealing performance and more effectively prevents water vapor from entering the drive shaft through this area.

[0034] Among them, the cross-sectional shape of the sealing groove can be wavy or serrated. When the seal 31 is pressed onto the wavy sealing groove, it will fit tightly onto the groove due to its own elasticity, thereby increasing the contact area and contact points between the seal 31 and the sealing groove to form a continuous sealing barrier, thereby improving the tightness and reliability of the seal.

[0035] See also Figure 1 As shown, in some embodiments, one end of the annular wall 12 away from the main body 11 is bent inward along its edge to form a buckle groove 121 , and one end of the docking portion 311 is fixed in the buckle groove 121 .

[0036] In this embodiment, the connection structure between the annular wall 12 and the docking portion 311 is further designed. If moisture wants to penetrate into the internal structure from the connection between the end of the annular wall 12 and the docking portion 311, it must break through the defense line formed by the tight fit between the docking portion 311 and the rebate groove 121. Since the docking portion 311 is firmly fixed in the rebate groove 121, there is almost no gap or channel between the two for moisture to penetrate, and the rebate groove 121 is formed by bending, which further increases the difficulty of penetration through the connection, thereby effectively blocking the intrusion of moisture and ensuring that the interior of the drive shaft sealing system 100 of the entire vehicle maintains a relatively dry environment.

[0037] Furthermore, the diameter of the notch of the rebate groove 121 increases gradually toward the inner direction of the groove, and the docking portion 311 is filled and fixed in the rebate groove 121. Due to the structural feature of the increasing diameter of the rebate groove 121, when the docking portion 311 is filled in, it can better fit the inner wall of the rebate groove 121.

[0038] On the one hand, from the perspective of assembly, this shape structure makes it easier for the docking part 311 to accurately enter the rebate groove 121 to complete the assembly process, which reduces the difficulty of assembly to a certain extent and improves the assembly efficiency. On the other hand, in terms of sealing and fixing effects, after the docking part 311 is filled in such a rebate groove 121 and fixed, the fit between the two will be tighter. Compared with the cooperation between the ordinary straight-cylindrical groove and the docking part 311, this increasing notch structure can allow the docking part 311 to have better contact with the groove wall at different positions, thereby further enhancing the stability of the connection and the sealing effect, more effectively preventing the occurrence of water seepage and the like, and ensuring that the vehicle's drive shaft sealing system 100 maintains good sealing and stability during operation.

[0039] It can be understood that the two ends of the intermediate shaft 20 are symmetrically connected with the drive shaft universal joints 10. Figure 2 The technical solution of this application only proposes a sealing structure between the intermediate shaft 20 and the universal joint 10 of the drive shaft on one side thereof. Similarly, the intermediate shaft 20 and the universal joint 10 of the drive shaft on the other side thereof adopt the same sealing structure for sealing, which will not be described in detail here.

[0040] See also Figure 3 As shown, in some embodiments, the driving shaft sealing system of the vehicle further includes a sealing detection component, which includes a water seepage sensor 42, a signal processing unit 41 and an alarm device 43. The water seepage sensor 42 is disposed in a chamber sealed by the sealing component; the signal processing unit 41 is electrically connected to the water seepage sensor 42, and is used to receive a signal from the water seepage sensor 42 and process it to obtain water seepage information to determine whether water seepage occurs; the alarm device 43 is electrically connected to the signal processing unit 41, and is used to send an alarm signal when water seepage is detected.

[0041] In this embodiment, the water seepage sensor 42 is arranged in the chamber enclosed by the sealing component, so that when water seepage occurs in the chamber, the water seepage sensor 42 can quickly sense the change of water content and generate a corresponding electrical signal. Among them, the number of water seepage sensors 42 can be set to one or more, so as to detect different sealing connection ports respectively, such as the connection between the ring wall and the seal and the connection between the seal and the intermediate shaft. Among them, the water seepage sensor 42 can be a resistive, capacitive or optical fiber sensor, which monitors the presence of water in real time. The signal processing unit 41 has a strong signal processing capability, and can filter, amplify, convert and process the received electrical signal, so as to extract useful water seepage information. Based on the processed water seepage information, the signal processing unit 41 can intelligently determine whether water seepage has occurred. The alarm device 43 is also connected to the signal processing unit 41 through an electrical connection, so as to send an alarm signal in time when water seepage is detected. Among them, the alarm device 43 has a variety of alarm modes, including sound alarm, light alarm and text alarm. These modes can be selected and combined according to actual needs and scenarios to ensure the clarity and effectiveness of the alarm signal. In this way, the sealing detection component can effectively monitor water seepage and send out an alarm signal, providing strong protection for the safe operation of the vehicle.

[0042] In some embodiments, the sealing detection assembly further includes a fault automatic calibration module 44 electrically connected to the signal processing unit 41 for periodically calibrating the water seepage sensor 42 .

[0043] In this embodiment, the accuracy and stability of the water seepage sensor 42 are ensured by setting up an automatic calibration module. Through reasonable settings and regular calibration, the reliability of the sealing detection system can be ensured, so that water seepage problems can be discovered and dealt with in a timely manner.

[0044] Among them, the automatic calibration module generates a known calibration signal, which simulates the water seepage situation and is used to test the response of the water seepage sensor 42. After receiving the calibration signal, the water seepage sensor 42 will generate a corresponding output signal. The automatic calibration module will measure this output signal and compare it with the expected response. If there is a deviation between the measured output signal and the expected response, the automatic calibration module will calculate the error and adjust the sensor according to the error size to reduce or eliminate the error. After each calibration, the automatic calibration module will record the calibration results, including the calibration time, the error before and after calibration, etc., for subsequent analysis and tracking.

[0045] In some embodiments, the alarm signal is connected to the vehicle system 50 to be displayed through the display screen in the vehicle system 50; and the water seepage information is automatically recorded and displayed by the vehicle system 50, and the water seepage information includes the time, location and severity of the water seepage.

[0046] The alarm signal is connected to the vehicle system 50 through a specific communication protocol or interface. When the water seepage sensor 42 detects water seepage and triggers an alarm, the display screen in the vehicle system 50 will immediately display the corresponding alarm information. This information is usually presented in a striking color (such as red) and an icon (such as a water drop icon) so that the driver can quickly notice it. In addition, the vehicle system 50 should provide an interactive function to allow the driver to view more detailed alarm information or confirm the alarm status.

[0047] For example, the time, location and severity of water seepage can be checked to facilitate subsequent maintenance and troubleshooting. Specifically, the vehicle system 50 will automatically record the water seepage information and save it in the system's memory. This information can be organized in chronological order or event type so that the driver or maintenance personnel can easily view it. Furthermore, the water seepage information can be presented in the form of a list, chart or map through the display screen of the vehicle system 50. For example, the location where the water seepage occurred can be marked on the map, and the time, location and severity of the water seepage event can be listed in the list.

[0048] Therefore, the alarm signal and water seepage information are integrated into the vehicle system 50, so that the driver can understand the vehicle status more intuitively, reducing omissions and misunderstandings caused by scattered information. Timely alarm and water seepage information records can help the driver quickly discover and deal with water seepage problems, improve maintenance efficiency, and thus avoid potential safety hazards.

All equivalent structural changes made using the contents of the present application specification and drawings under the overall concept of the present application, or direct / indirect application in other related technical fields are included in the scope of protection of the present application.
