For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; and direct connections or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the embodiments of the present invention based on the specific circumstances.

[0037] In the description of this specification, the reference terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" mean that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the embodiment of the present invention. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification and features of different embodiments or examples without contradiction.

[0038] The following combination Figures 1 to 4 It should be understood that the following description is merely an illustrative embodiment of the present invention and does not constitute a limitation on the present invention.

[0039] like Figure 1 and Figure 2 As shown, a first aspect of the present invention provides a vehicle shift assembly, comprising: an active member 110 and a mating member 120 , wherein the active member 110 can move relative to the mating member 120 to adjust the vehicle gear position.

[0040] Among them, an oil guide channel 105 is formed in the active component 110, and an oil inlet 101 and an oil outlet 106 connected to the oil guide channel 105 are opened on the active component 110. The oil inlet 101 is used to inject lubricating oil, and the oil outlet 106 is used to discharge lubricating oil to lubricate the contact part of the active component 110 and the mating component 120.

[0041] The vehicle shift assembly provided by the present invention forms an oil guide channel 105 in the active part 110, injects lubricating oil from the oil inlet 101 of the oil guide channel 105, and lubricating oil flowing out from the oil outlet 106 of the oil guide channel 105 lubricates the contact portion between the active part 110 and the mating part 120, so that any structure of the vehicle shift assembly can be lubricated by opening the oil guide channel 105 in the active part 110, thereby achieving long-term use and effective lubrication of the vehicle shift assembly.

[0042] Regarding the influence of the movement states of the active member 110 and the mating member 120 on the opening and closing states of the oil outlet 106 of the oil guide channel 105 , in one embodiment of the present invention, the active member 110 and the mating member 120 can switch between a first state and a second state.

[0043] In the first state, the oil outlet 106 is open and the lubricating oil in the oil guide channel 105 flows out; in the second state, the oil outlet 106 is closed and no lubricating oil flows out.

[0044] For further explanation of the second state, in this embodiment, the second state may be a neutral state, which refers to a state where the vehicle's joystick is not engaged in any forward or reverse gear and the transmission is completely separated from the drive wheels. The neutral position of a manual transmission is in the middle position.

[0045] For further explanation of the first state, in this embodiment, the first state may be a gear selection state, and the second state may be a neutral state.

[0046] Specifically, the gear selection and shifting state includes the gear selection process and the gear shifting process. For example, when a vehicle needs to be engaged in first gear, and the vehicle lever needs to be shifted from neutral to first gear, the process from when the vehicle lever moves from neutral to first gear but does not enter first gear is considered a gear selection process. Similarly, when the vehicle lever moves from first gear to neutral, i.e., shifting back, it is also considered a gear selection process. In other words, the gear selection state described in the present invention refers to the process of the vehicle lever moving between gears.

[0047] The shifting process involves, for example, shifting a vehicle into first gear. After reaching first gear, i.e., directly facing first gear, through the gear selection process, and then further shifting into first gear, while maintaining the vehicle's joystick in first gear, this constitutes the shifting process. In other words, the shifting state described in the present invention refers to the state in which the vehicle's joystick is in a gear position other than neutral.

[0048] In other words, in the gear selection state, the active member 110 and the mating member 120 are in a lubricating oil lubricated state, and in the neutral state, the active member 110 and the mating member 120 do not move relative to each other and therefore do not require lubrication.

[0049] In another embodiment of the present invention, the relative position of the active component 110 and the matching component 120 may be monitored by a sensor, thereby controlling the opening and closing of the oil outlet 106 of the oil guide channel 105 .

[0050] Specifically, the second state is set as the initial state. When the sensor detects that the active part 110 and the matching part 120 are in the second state, i.e., the initial state, the oil outlet 106 does not discharge oil. The first state is set as the oil discharge state. When the sensor detects that the active part 110 and the matching part 120 have relative displacement, i.e., they are in the first state, the oil outlet 106 discharges oil for lubrication.

[0051] Continue to refer Figure 1 and Figure 2 In one embodiment of the present invention, the active component 110 is a connecting rod 202, and the matching component 120 is a ball head seat 201. The connecting rod 202 includes a rod body and a ball head 203 provided at one end of the rod body, and the ball head 203 matches the ball head seat 201.

[0052] The specific matching state of the ball head 203 and the ball head seat 201 is: when the vehicle joystick 100 is in the second state, the ball head 203 and the ball head seat 201 are tightly fitted. In order to achieve a better fitting state, a sealing structure is provided between the ball head 203 and the ball head seat 201.

[0053] In particular, the end of the ball head 203 fits tightly against the sealing structure.

[0054] In an optional embodiment of the present invention, a gear selection rocker arm 301 and a gear shift rocker arm 302 are mounted on the connecting rod 202 .

[0055] When the vehicle joystick 100 is in the first state, the ball head 203 is supported by a certain point at the end portion and rotates around the point in the forward, backward, left, and right directions.

[0056] Furthermore, in another embodiment of the present invention, Figure 2 As shown, the oil guide channel 105 is opened on the connecting rod 202 .

[0057] The oil inlet 101 is provided on the rod body of the connecting rod 202 , and the oil outlet 106 is provided on the ball head 203 of the connecting rod 202 .

[0058] In this embodiment, the oil outlet 106 is opened at the end of the ball head 203 and is located beside the lowest point of the end, that is, away from the lowest point.

[0059] For the lubrication process of the ball head 203 and the ball head seat 201 , lubricating oil is injected into the oil inlet 101 , and the lubricating oil flows in the entire oil guide channel 105 .

[0060] When the vehicle joystick 100 is in the second state, the oil outlet 106 is blocked due to the close fit between the ball head 203 and the ball head seat 201 .

[0061] When the vehicle joystick 100 is in the first state, since the ball head 203 moves around the point relative to the ball head seat 201, the oil outlet 106 is opened, and the lubricating oil flows out, thereby completing the lubrication process.

[0062] like Figure 3 As shown, in one embodiment of the present invention, the active member 110 is a stop assembly and the mating member is a ratchet 230 , and the stop assembly is in contact with the ratchet 230 .

[0063] Furthermore, in the embodiment, the stopper assembly includes a connecting fork 210 and a stopper plug 220 .

[0064] The stopper 220 is disposed inside the connecting fork 210 and exposed from the bottom of the connecting fork 210 to engage with the ratchet 230 . A spring 240 is provided between the stopper 220 and the connecting fork 210 to enable the stopper 220 to move relative to the connecting fork 210 .

[0065] The specific matching relationship between the stop assembly and the ratchet 230 is as follows: a cavity is opened in the middle of the connecting fork 210, a stop plug 220 is placed in the cavity, and a spring 240 is provided between the stop plug 220 and the bottom of the cavity.

[0066] The stopper 220 performs linear reciprocating motion in the cavity of the connecting fork 210 .

[0067] Specifically, the stopper 220 includes a guide post at an upper end and a bottom at a conical end. The guide post is in contact with the cavity and can move relatively. The conical end is in contact with the ratchet 230 .

[0068] Furthermore, the ratchet 230 includes a recess and a peak protruding outside the recess.

[0069] When the vehicle joystick 100 is in the second state, the conical end of the stopper 22 cooperates with the recess of the ratchet 230; when the vehicle joystick 100 is in the first state, the conical end of the stopper 220 moves around the point to the peak position of the ratchet 230 with the stopper 220 as support.

[0070] In one embodiment of the present invention, the oil guide channel 105 is opened on the connecting fork 210, the oil inlet 101 is opened at the upper part of the connecting fork 210, the oil outlet 106 is opened at the lower part of the connecting fork 210, and the oil outlet 106 is opened on the side close to the stopper 220.

[0071] In an optional embodiment of the present invention, the ratchet 230 is connected to a gear selection rocker arm 301 and a gear shift rocker arm 302 .

[0072] Further explanation of the locations of the oil inlet 101 and oil outlet 106 of the oil guide channel 105. In this embodiment, the oil inlet 101 is located at the upper end of the connecting fork 210 and communicates with the outside. The oil outlet 106 is located at the lower end of the connecting fork 210 and is located on the inner wall of the cavity of the connecting fork 210.

[0073] When the vehicle joystick 100 is in the second state, the guide post of the stopper 220 blocks the oil outlet 106 .

[0074] When the vehicle joystick 100 is in the first state, the stopper 220 moves around a point. During the movement, the stopper 220 compresses the spring 240 , and the stopper 220 is in a state of being retracted into the cavity of the connecting fork 210 .

[0075] As a result, the oil outlet 106 is exposed, and the lubricating oil flows along the stopper 220 and between the stopper 220 and the ratchet 230 to achieve lubrication.

[0076] In other words, the stopper 220 moves linearly upward relative to the connecting fork 210, the spring 240 is compressed, and a gap is exposed in the oil outlet 106. The lubricating oil flows out from the gap exposed in the oil outlet 106 and flows into the contact point between the stopper 220 and the ratchet 230 to achieve lubrication.

[0077] like Figures 1 to 4 As shown, in an embodiment of the second aspect of the present invention, a vehicle control assembly is provided, including a shift lever 100 and the vehicle shift assembly in the embodiment of the first aspect described above.

[0078] The shift lever 100 is assembled to the active component 110 to drive the vehicle shift assembly to adjust the gear position.

[0079] refer to Figure 2 and Figure 4An oil storage tank 102 is provided inside the shift lever 100 . The oil storage tank 102 includes an oil filling port 103 and an oil guide port 104 . The oil filling port 103 is used to inject lubricating oil. The oil guide port 104 is connected to the oil inlet 101 of the oil guide channel 105 .

[0080] In this embodiment, the oil filling port 103 is communicated with the outside.

[0081] refer to Figure 2 In the vehicle shift assembly in which the ball head 203 cooperates with the ball head seat 201 , the oil guide port 104 of the oil storage tank 102 opened on the shift lever 100 is connected to the oil inlet 101 opened on the connecting rod 202 .

[0082] The number of the oil guide ports 104 of the oil storage tank 102 is set according to the number of the oil inlet ports 101. Meanwhile, the oil storage tank 102 can be annularly grooved or core grooved.

[0083] The oil storage tank 102 can store the lubricating oil after the lubricating oil is injected through the oil filling port 103 , and the oil filling port 103 is sealed to facilitate the subsequent injection of lubricating oil at any time.

[0084] refer to Figure 4 In the vehicle shift assembly in which the stopper 220 cooperates with the ratchet, the vehicle shift lever 100 is inserted into the upper groove of the connecting fork 210. The oil inlet 101 of the oil guide channel 105 provided on the connecting fork 210 is communicated with the oil guide port 104 of the oil storage tank 102.

[0085] In actual operation, the oil inlet 101 of this embodiment is opened on the inner side wall of the groove where the vehicle control lever 100 is placed. At the same time, the oil storage tank 102 can be an annular groove or a core groove.

[0086] The oil storage tank 102 can be connected to the outside through the oil filling port 103. After the lubricating oil is injected, the lubricating oil is stored, and the oil filling port 103 is sealed to facilitate the subsequent injection of lubricating oil at any time.

[0087] In a third aspect of the present invention, an embodiment provides a motor vehicle comprising the vehicle shift assembly described in the first aspect or the vehicle control assembly described in the second aspect.

[0088] Furthermore, the control assembly and motor vehicle provided by the present invention also include the above vehicle shift assembly structure, so the control assembly and motor vehicle also have the above advantages.

[0089] Since the shift assembly at the bottom of the vehicle's joystick is generally a metal part and is easily worn due to frequent relative movement over a long period of time, which affects its service life, an oil guide channel structure is added and the relative movement of the shift assembly during the gear selection and shifting operations is used to directly control the opening and closing of the oil outlet of the oil guide channel, thereby realizing the self-lubricating function of the speed control assembly on the shift part, thereby achieving the purpose of reducing friction, reducing abnormal noise, and extending the life of the metal shift part.

[0090] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
