[0034] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0035] Reference below Figures 1-6 A vehicle oil relief valve 100 and a vehicle having the same according to an embodiment of the present invention will be described.

[0036] like Figure 1 and Figure 2 As shown, the oil overflow valve 100 of a vehicle according to an embodiment of the present utility model includes: a valve body 1, an opening and closing member 2, a valve stem 3 and an operating member 4. The valve body 1 is suitable for being arranged in a gearbox housing. The valve body 1 defines an oil drain channel 11 and an installation space 12. The opening and closing member 2 is arranged in the installation space 12 and can rotate so that the oil drain channel 11 is cut off or connected. When the oil drain channel 11 is connected, the transmission oil in the transmission housing can flow out of the transmission housing through the oil drain channel 11. The valve stem 3 is connected to the opening and closing member 2. The operating member 4 includes a first sub-operating member 41 and a second sub-operating member 42. The first sub-operating member 41 is connected to the valve stem 3, and the second sub-operating member 42 is rotatably connected to the first sub-operating member 41. The operating member 4 is used to drive the valve stem 3 to rotate to drive the opening and closing member 2 to rotate.

[0037] Among them, the valve body 1 of the oil overflow valve 100 can be connected to the gearbox housing, the valve body 1 can define an installation space 12, the opening and closing part 2 of the oil overflow valve 100 can be arranged in the installation space 12, the opening and closing part 2 can rotate in the installation space 12, the valve stem 3 of the oil overflow valve 100 can be connected to the opening and closing part 2, and the operating part 4 can be connected to the valve stem 3. By rotating the operating part 4, the valve stem 3 can be driven to rotate, and the rotation of the valve stem 3 can drive the opening and closing part 2 to rotate. The rotation of the opening and closing part 2 can cause the oil drain channel 11 to be cut off or opened. When the oil drain channel 11 is opened, the transmission oil can flow out of the transmission housing through the oil drain channel 11 of the valve body 1, so as to detect whether the transmission oil of the transmission is sufficient or not. When the oil drain channel 11 is cut off, the transmission oil is blocked by the opening and closing part 2 and cannot flow out through the oil overflow valve 100.

[0038] One end of the first sub-operating member 41 of the operating member 4 is connected to the valve stem 3, and the other end of the first sub-operating member 41 is rotatably connected to one end of the second sub-operating member 42 of the operating member 4. By rotating the second sub-operating member 42 so that its extension direction is approximately the same as that of the first sub-operating member 41, the lever arm of the operating member 4 is increased. This allows the valve stem 3 to be rotated with a relatively small force, thereby driving the opening and closing member 2 to rotate, thereby controlling whether the oil drain passage 11 is blocked or opened. The provision of the first and second sub-operating members 41, 42, facilitates the operation of the oil overflow valve 100, opening or closing it, thereby facilitating the detection of transmission oil sufficiency. Moreover, when the oil overflow valve 100 is not in use, the second sub-operating member 42 can be rotated to a position close to the valve body 1 (the first sub-operating member 41 and the second sub-operating member 42 have an angle, for example, vertical), so that it occupies a smaller space, reducing the risk of interference between the second sub-operating member 42 and other components, and increasing the practicality of the oil overflow valve 100. In addition, the operating member 4 and the opening and closing member 2 are not easily damaged, have a reliable structure, and can be reused, so that the oil overflow valve 100 can accompany the entire life cycle of the gearbox, thereby saving costs.

[0039] To check whether the transmission oil level is sufficient, the second sub-control member 42 can be rotated so that the first sub-control member 41 and the second sub-control member 42 are approximately horizontal. The control member 4 is then rotated to drive the opening and closing member 2 to rotate. This rotation of the opening and closing member 2 opens the oil drain channel 11. If oil flows out of the oil drain channel 11, or if a cloth strip is inserted into the oil drain channel 11 and becomes soaked with oil, the transmission oil level is sufficient. Otherwise, the transmission oil level is insufficient and needs to be replenished. Furthermore, if oil flows out of the oil drain channel 11 during replenishment, the transmission oil level is sufficient.

[0040] In the above embodiment, by providing an oil overflow valve 100 having an operating member 4 connected to the valve stem 3, the operating member 4 of the oil overflow valve 100 can be rotated to open the oil drain channel 11 to detect whether the transmission oil in the transmission housing is sufficient. The oil overflow valve 100 is easy to open, which helps to reduce the difficulty of checking the transmission oil. The oil overflow valve 100 has a reliable structure and a long service life. It does not need to be repeatedly replaced and can accompany the entire life cycle of the transmission, which can save costs.

[0041] In some embodiments of the present invention, Figures 1-4 As shown, the control member 4 further includes: a third sub-control member 43 , and the third sub-control member 43 is rotatably connected to the second sub-control member 42 .

[0042] One end of the third sub-control member 43 of the control member 4 is rotatably connected to the end of the second sub-control member 42 that is away from the first sub-control member 41. By rotating the second and third sub-control members 42, 43, the first, second, and third sub-control members 41, 42, 43 can be aligned in substantially the same direction. This further increases the lever arm of the control member 4, facilitating rotation of the valve stem 3 with less force, making it easier to control the flow of the oil drain passage 11, and further enhancing the practicality and reliability of the oil overflow valve 100. Furthermore, because the third sub-control member 43 is rotatably connected to the second sub-control member 42, the space occupied by the oil overflow valve 100 can be reduced by properly rotating the second and third sub-control members 42, thereby improving space utilization.

[0043] In some embodiments of the present invention, Figure 1-Figure 3 As shown, the oil overflow valve 100 also includes: a limit member 5, one end of the valve stem 3 extends into the installation space 12 and is connected to the opening and closing member 2, and the limit member 5 is connected to the other end of the valve stem 3 to limit part of the first sub-operating member 41 between the limit member 5 and the valve body 1.

[0044] Among them, along the extension direction of the valve stem 3, the limiter 5, part of the first sub-operating member 41, and the valve body 1 of the oil overflow valve 100 are arranged in sequence. The limiter 5 can be fixedly connected to the valve stem 3. The limiter 5 and the valve body 1 jointly define an assembly space. Part of the first sub-operating member 41 can be located within the assembly space. In other words, part of the first sub-operating member 41 can be confined between the limiter 5 and the valve body 1. In addition, one end of the valve stem 3 can extend into the installation space 12 and be connected to the opening and closing member 2. By providing the limiter 5, part of the first sub-operating member 41 can be confined between the limiter 5 and the valve body 1, reducing the risk of the first sub-operating member 41 being separated from the valve stem 3 and improving the reliability of the oil overflow valve 100.

[0045] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the valve body 1 further defines a flow guiding channel 13 and an oil outlet 14 . The flow guiding channel 13 is connected between the oil discharge channel 11 and the oil outlet 14 . The extending direction of the flow guiding channel 13 and the extending direction of the oil discharge channel 11 form an angle.

[0046] Among them, the guide channel 13 of the valve body 1 can be connected between the oil drain channel 11 and the oil outlet 14. When the oil drain channel 11 is connected, the transmission oil in the transmission housing can flow out of the oil overflow valve 100 through the oil drain channel 11, the guide channel 13 and the oil outlet 14 in sequence. The extension direction of the guide channel 13 and the extension direction of the oil drain channel 11 can have an angle. As some embodiments of the present application, the angle between the axial direction of the guide channel 13 and the vertical direction is less than 90°, so that the transmission oil can flow downward along the guide channel 13 through the oil outlet 14. The guide channel 13 and the oil outlet 14 can guide the outflowing transmission oil, avoid splashing of the transmission oil, reduce the steps required to wipe and clean the oil, and reduce the probability of the transmission oil contaminating other components, so as to keep the transmission and other components clean.

[0047] As some embodiments of the present application, a container may be used to receive the outflowing transmission oil so as to collect the outflowing transmission oil.

[0048] As a specific embodiment of the present application, the extension direction of the guide channel 13 and the extension direction of the oil drain channel 11 can be perpendicular to each other, so that the transmission oil can flow down from the guide channel 13 more easily, which is convenient for judging whether the transmission oil in the transmission is sufficient or not, and is also convenient for using a container to receive the outflowing transmission oil.

[0049] In some embodiments of the present invention, Figure 4 and Figure 5 As shown, the outer wall of the valve stem 3 has two opposite first mating planes 31, the first sub-operating member 41 has a first mating hole 411, the inner wall of the first mating hole 411 has two opposite second mating planes 412, and the valve stem 3 is passed through the first mating hole 411 so that the two first mating planes 31 are mated one by one with the two second mating planes 412.

[0050] Among them, the inner wall of the first matching hole 411 may include two opposite second matching planes 412. When the valve stem 3 is inserted into the first matching hole 411 of the first sub-operating component 41, the two first matching planes 31 of the valve stem 3 can be matched one by one with the two second matching planes 412 of the first matching hole 411 to prevent the valve stem 3 from rotating in the first matching hole 411 (that is, to prevent the valve stem 3 and the first sub-operating component 41 from rotating relative to each other), so that the rotation of the first sub-operating component 41 can reliably drive the valve stem 3 to rotate, and then drive the opening and closing component 2 to rotate to control the opening and closing of the guide channel 13, so as to achieve the effect of controlling the opening and closing of the oil overflow valve 100 through the first sub-operating component 41. By making the two first matching planes 31 match one by one with the two second matching planes 412, the structure of the oil overflow valve 100 can be simple, the assembly is convenient, the matching effect is good, and the reliability of the use of the oil overflow valve 100 is increased.

[0051] In some embodiments of the present invention, Figure 5 and Figure 6 As shown, the outer wall of the valve stem 3 has two opposite third mating surfaces 32, the opening and closing member 2 has a mating groove 21 at one end facing the valve stem 3, the inner wall of the mating groove 21 has two opposite fourth mating planes 23, and part of the structure of the valve stem 3 is arranged in the mating groove 21 so that the two third mating planes are mated one by one with the two fourth mating planes 23.

[0052] Among them, the opening and closing part 2 can have a mating groove 21 at one end facing the valve stem 3. When part of the structure of the valve stem 3 is arranged in the mating groove 21, the two third mating surfaces 32 of the valve stem 3 can be matched one by one with the two fourth mating planes 23 of the mating groove 21 to prevent the valve stem 3 from rotating in the mating groove 21 (that is, to prevent the valve stem 3 and the opening and closing part 2 from rotating relative to each other). The rotation of the valve stem 3 can drive the opening and closing part 2 to rotate to control the opening and closing of the guide channel 13, thereby achieving the effect of controlling the opening and closing of the oil overflow valve 100 through the valve stem 3. By making the two third mating surfaces 32 match one by one with the two fourth mating planes 23, the structure of the oil overflow valve 100 can be simple, the assembly is convenient, the mating effect is good, and the reliability of the use of the oil overflow valve 100 is increased.

[0053] In some embodiments of the present invention, Figure 2 As shown, part of the installation space 12 is constructed as part of the oil drain channel 11, and the opening and closing member 2 is constructed as a ball head, which has a conducting channel 22 running through it. The ball head can be rotated to cut off the oil drain channel 11 or to connect the conducting channel 22 with the oil drain channel 11, so that the oil drain channel 11 is cut off or connected.

[0054] Among them, the opening and closing part 2 can be constructed as a ball head, the ball head can be arranged in the installation space 12, the ball head can have a conducting channel 22 running through it, and part of the installation space 12 can be constructed as part of the oil drain channel 11. When the ball head rotates, the conducting channel 22 can be connected to the oil drain channel 11 to make the oil drain channel 11 conductive, even if the oil drain channel 11 is connected to the guide channel 13, or, the oil drain channel 11 can be cut off by the ball head to disconnect the oil drain channel 11 from the guide channel 13, and then the oil drain channel 11 can be controlled to be cut off or connected by rotating the ball head. The operation is simple and convenient, easy to implement, and the structure is compact, which can increase the practicality of the oil overflow valve 100.

[0055] In some embodiments of the present invention, Figure 1 and Figure 2As shown, the valve body 1 includes: a valve seat 15, a valve bonnet 16, and a guide portion 17. The valve bonnet 16 defines an installation space 12, one end of which is open. The valve seat 15 is connected to the valve bonnet 16 and covers the open end. The valve seat 15 is suitable for being provided in a transmission housing. The valve seat 15 and the valve bonnet 16 jointly define an oil drain passage 11. The guide portion 17 is connected to the valve bonnet 16 and defines a guide passage 13 and an oil outlet 14.

[0056] Among them, the valve cap 16 of the valve body 1 can define an installation space 12, one end of the installation space 12 can be open, the valve seat 15 of the valve body 1 can be connected to the valve cap 16 to cover the open end, the valve seat 15 and the valve cap 16 can jointly define an oil drain channel 11, the guide portion 17 can be connected to the valve cap 16, the guide portion 17 can define a guide channel 13 and an oil outlet 14, the transmission oil in the gearbox can flow through the oil drain channel 11, the guide channel 13 and the oil outlet 14 in sequence and flow out, which can be used to judge whether the transmission oil in the gearbox is sufficient. The valve body 1 has a simple and reasonable structure, is easy to process and manufacture, is easy to put into actual use, and has good reliability, safety and practicality.

[0057] As some embodiments of the present application, the outer wall of the valve seat 15 of the valve body 1 can be constructed with a first thread, and the gearbox housing can be constructed with a second thread that cooperates with the first thread. The valve seat 15 is threadedly connected to the gearbox housing so that the valve seat 15 can be fixed to the gearbox housing.

[0058] As some embodiments of the present application, the first thread of the valve seat 15 may be coated with sealant to reduce the risk of transmission oil leakage from the first thread.

[0059] As some embodiments of the present application, the valve seat 15 and the valve bonnet 16 can be separate parts, and the valve seat 15 and the valve bonnet 16 can be designed and manufactured separately, which can reduce the design difficulty, replace failed parts, and improve the practicality of the oil overflow valve 100.

[0060] As some embodiments of the present application, the guide part 17 and the valve cap 16 can be integrally formed. The integrally formed part has good structural strength, which can reduce the risk of breakage at the connection between the guide part 17 and the valve cap 16 and improve the connection stability between the guide part 17 and the valve cap 16.

[0061] As some embodiments of the present application, the guide portion 17 and the valve cap 16 can be separate parts, and the guide portion 17 and the valve cap 16 can be designed and manufactured separately, which can reduce the design difficulty, replace failed parts, and improve the practicality of the oil overflow valve 100.

[0062] In some embodiments of the present invention, Figure 2As shown, the oil overflow valve 100 also includes: a first sealing member 6 and a second sealing member 7.

[0063] Among them, the first seal 6 and the second seal 7 of the oil overflow valve 100 can be arranged in the installation space 12. Along the extension direction of the oil drain channel 11, the first seal 6 can be sealed between the opening and closing part 2 and the valve seat 15, and the second seal 7 can be sealed between the opening and closing part 2 and the bottom wall of the installation space 12. The first seal 6 and the second seal 7 can both be used to seal the oil overflow valve 100, reduce the risk of oil leakage of the oil overflow valve 100, maintain the reliability and cleanliness of the oil overflow valve 100, reduce the risk of the valve stem 3 being corroded by the gearbox oil and difficult to rotate, extend the service life of the oil overflow valve 100, and enable the oil overflow valve 100 to accompany the entire life cycle of the gearbox, thereby saving costs.

[0064] As some embodiments of this application, Figure 2 As shown, the first seal 6 and the second seal 7 can be constructed into an arc shape at one end facing the opening and closing member 2.

The valve stem 3 may further include a flange 33, which may be located within the installation space 12 to reduce the risk of the valve stem 3 being separated from the valve bonnet 16. The third sealing strip 8 may be located between the flange 33 and the inner wall of the valve bonnet 16 to enhance the sealing between the valve stem 3 and the valve bonnet 16. By providing the first sealing strip 61, the second sealing strip 71, and the third sealing strip 8, the sealing of the oil overflow valve 100 may be further enhanced, the risk of oil leakage from the oil overflow valve 100 may be reduced, and the oil overflow valve 100 may be kept clean.
