Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

It should be appreciated that reference throughout this specification to "one embodiment" or "an embodiment" means that a particular feature, structure or characteristic described in connection with the embodiment is included in at least one embodiment of the present application. Thus, the appearances of the phrases "in one embodiment" or "in an embodiment" in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

As shown in fig. 1 to 4, the shift mechanism 1000 includes: base 10, shift lever assembly 20 and gear assembly 30.

The shift lever assembly 20 and the gear assembly 30 are both disposed on the base 10. The gear assembly 30 is provided with a shift groove 31 and a selection groove 32, the shift groove 31 is communicated with the selection groove 32, the middle part of the bottom of the shift groove 31 protrudes towards the direction of the notch, the gear shift lever assembly 20 is suitable for being abutted against the bottom of the shift groove 31, and the gear shift lever assembly 20 is suitable for sliding in the shift groove 31 and the selection groove 32. The gear assembly 30 is used to generate a shifting force to the shift lever assembly 20 when the shift lever assembly 20 abuts the floor of the shift slot 31 and the shift lever assembly 20 slides within the shift slot 31. It should be noted that the shifting force refers to a resistance force applied to the shift lever assembly 20 during the swinging process, and a user usually determines whether the shift is effective, in place, accurate, and the like by sensing the shifting force during the operation of the shift lever assembly 20, and obtains a corresponding operation experience.

In the embodiment of the present application, since the middle of the bottom of the shift groove 31 protrudes toward the direction of the notch, the shift lever assembly 20 is adapted to abut against the bottom of the shift groove 31, and the shift lever assembly 20 is adapted to slide in the shift groove 31 and the select groove 32, so that when the shift lever assembly 20 abuts against the bottom of the shift groove 31 and when the shift lever assembly 20 slides in the shift groove 31, the pressure between the shift lever assembly 20 and the shift groove 31 is changed, so that the shift lever assembly 20 generates a variable shifting force during the sliding. Since the shift gate 31 communicates with the selection gate 32, the shift lever assembly 20 can enter different shift gates 31 through the selection gate 32, thereby shifting gears. Specifically, when the gear shift lever assembly 20 slides to the gear shift groove 31 from the gear shift groove 32, the pressure of the gear shift groove 31 to the gear shift lever assembly 20 is firstly increased and then decreased, so that the gear shift lever assembly 20 slowly slides firstly, and then quickly slides to one end of the gear shift groove 31 far away from the gear shift groove 32 after passing through the middle of the gear shift groove 31, so that a user has a suction feeling when operating the gear shift lever assembly 20, and meanwhile, the middle part of the bottom of the gear shift groove 31 protrudes to limit the gear shift lever assembly 20, and the gear shift lever assembly 20 is prevented from sliding back to the gear shift groove 32. That is, in the embodiment of the present application, by setting the middle portion of the groove bottom of the shift groove 31 to be protruded toward the direction of the groove opening, when the shift lever assembly 20 is supported by the groove bottom of the shift groove 31 and the shift lever assembly 20 slides on the groove bottom of the shift groove 31, the pressure between the shift lever assembly 20 and the groove bottom of the shift groove 31 can be changed, and then the shift lever assembly 20 generates a variable shifting force, so that the operation feeling of using the shift lever assembly 20 by a user is improved, and the user experience of a vehicle or a coach car with game function is greatly improved.

It should be noted that since the shift gate 32 is in communication with the shift gate 31, different gears can be engaged when the shift lever assembly 20 is moved from the shift gate 32 to a different shift gate 31. For example, the number of shift grooves 31 is 7, and one shift groove 31 corresponds to one gear, in this case, 7 shift grooves 31 may correspond to 1, 2, 3, 4, 5, 6, and R gears (i.e., reverse gears), and the selection groove 32 may correspond to a neutral gear. The selector groove 32 can communicate with 7 shift grooves 31. For example, when the shift lever assembly 20 is slid into the shift gate 31 corresponding to gear 1, the shift mechanism is shifted to gear 1.

In addition, in the embodiment of the present application, the number of the shift grooves 31 may be set according to actual needs, and the number of the shift grooves 31 is not limited herein in the embodiment of the present application.

Additionally, in some embodiments, as shown in fig. 5, a telescopic structure 40 may be provided on the shift lever assembly 20, the telescopic structure 40 cooperating with the shift gate 31 or the select gate 32.

When the telescopic structure 40 is disposed on the shift lever assembly 20 and the telescopic structure 40 is engaged with the shift slot 31 or the gear selection slot 32, the telescopic structure 40 may be partially located in the shift slot 31 or the gear selection slot 32, and during the movement of the shift lever assembly 20, the shift lever assembly 20 may drive the telescopic structure 40 to move, so that the telescopic structure 40 may move in the shift slot 31 or the gear selection slot 32. At this time, when the shift lever assembly 20 abuts against the bottom of the shift groove 31 and slides in the shift groove 31, actually, the telescopic structure 40 abuts against the bottom of the shift groove 31 and the telescopic structure 40 slides in the shift groove 31, at this time, since the middle part of the bottom of the shift groove 31 protrudes toward the direction of the notch, in the process of sliding the telescopic structure 40 in the shift groove 31, the pressure between the shift lever assembly 20 and the shift groove 31 will change, so that the telescopic amount of the telescopic structure 40 changes, and the sliding of the shift lever assembly 20 in the shift groove 31 is smoother. That is, by providing the telescopic structure 40 on the shift lever assembly 20, it is possible to facilitate the pressure between the shift lever assembly 20 and the shift gate 31 to change when the shift lever assembly 20 moves, so that the shift lever assembly 20 generates a shifting force with more operational feeling.

In addition, in the embodiment of the present application, as shown in fig. 5, the telescopic structure 40 may include a fixing sleeve 41, a first elastic member 42, and an abutting member 43. The first end of the fixing sleeve 41 is fixed on the gear shift lever assembly 20, the first elastic member 42 is embedded in the fixing sleeve 41, and the abutting member 43 is at least partially embedded in the fixing sleeve 41, the first end of the first elastic member 42 abuts against the inner wall of the fixing sleeve 41, the second end of the first elastic member 42 abuts against the first end of the abutting member 43, and the second end of the abutting member 43 is matched with the gear shift slot 31 or the gear selection slot 32. When the abutment 43 abuts against the bottom of the shift groove 31 and the abutment 43 slides in the shift groove 31, a variable shifting force is generated by the shift lever assembly 20.

Since the first end of the fixing sleeve 41 is fixed on the shift lever assembly 20, the first elastic member 42 is embedded in the fixing sleeve 41, and the abutting member 43 is at least partially embedded in the fixing sleeve 41, the first end of the first elastic member 42 abuts against the inner wall of the fixing sleeve 41, and the first end of the first elastic member 42 abuts against the inner wall of the fixing sleeve 41, the first elastic member 42 can provide elastic force to the abutting member 43, and the abutting member 43 can also provide pressure to the first elastic member 42, so that the first elastic member 42 is pressed. Since the second end of the abutting member 43 is engaged with the shift groove 31 or the select groove 32, the abutting member 43 can abut against the groove bottom of the shift groove 31, and the abutting member 43 can slide in the shift groove 31. Since the middle of the bottom of the shift slot 31 protrudes toward the direction of the notch, when the gear shift lever assembly 20 drives the telescopic assembly to enter the shift slot 31, at this time, the abutting member 43 abuts against the first end of the shift slot 31, and the first elastic member 42 can receive the compression force of the abutting member 43, so that the first elastic member 42 has a certain amount of compression, and the abutting member 43 can be partially embedded into the fixing sleeve 41. Here, the first end of the shift groove 31 refers to an end communicating with the select groove 32.

As shown in fig. 6 to 9, when the shift lever assembly 20 drives the telescopic assembly to slide in the shift slot 31, that is, the abutting member 43 slides in the shift slot 31, in the process that the abutting member 43 moves along the first end of the shift slot 31 to the middle of the shift slot 31, because the middle of the shift slot 31 protrudes toward the notch, the pressing force of the abutting member 43 by the slot bottom gradually increases, the compression force of the first elastic member 42 by the abutting member 43 gradually increases, so that the compression amount of the first elastic member 42 gradually increases, and further, the portion of the abutting member 43, which is embedded into the fixing sleeve 41, gradually increases. When the holding member 43 slides to the top of the bottom of the shifting groove 31, at this time, the compression force provided by the holding member 43 to the first elastic member 42 is the largest, that is, the first elastic member 42 receives the largest compression force of the holding member 43, so that the compression amount of the first elastic member 42 reaches the largest, and the part of the holding member 43, which is embedded into the fixing sleeve 41, is the largest. When the abutting member 43 continues to slide at the bottom of the shift slot 31, that is, the abutting member 43 slides along the middle of the shift slot 31 to the second end of the shift slot 31, the compression force provided by the abutting member 43 to the first elastic member 42 is gradually reduced, that is, the compression force applied to the first elastic member 42 by the abutting member 43 is gradually reduced, and the compression amount of the first elastic member 42 is gradually reduced, so that the portion of the abutting member 43 embedded in the fixing sleeve 41 is gradually reduced. Since the abutting member 43 continuously provides a compression force to the first elastic member 42 in the process that the abutting member 43 slides in the shifting chute 31, that is, the first elastic member 42 continuously receives the compression force of the abutting member 43, the first elastic member 42 also continuously applies an elastic force to the abutting member 43, so that when the abutting member 43 moves in the shifting chute 31, a certain friction force is provided, and the shift lever assembly 20 drives the telescopic assembly to slide in the shifting chute 31, that is, when the shift lever assembly 20 drives the abutting member 43 to slide in the shifting chute 31, the shift lever assembly 20 generates a variable shifting force.

It should be noted that, in practical applications, a user usually applies an external force to the shift lever assembly 20 to move the shift lever assembly 20, and the shift lever assembly 20 can drive the telescopic assembly to slide in the shift slot 31, i.e. the abutting member 43 can slide in the shift slot 31. And, when the user applies an external force to the shift lever assembly 20 to make the abutting member 43 slide in the shift slot 31, the abutting member 43 is usually made to move from the first end of the shift slot 31 to the vertex of the middle of the shift slot 31, in this process, since the abutting member 43 needs to continuously compress the first elastic member 42, the first elastic member 42 continuously provides an elastic force to the abutting member 43, and the elastic force continuously changes, so that the pressure between the abutting member 43 and the shift slot 31 changes when the abutting member 43 slides in the shift slot 31, and then the abutting member 43 transmits the pressure change to the shift lever assembly 20, and the shift lever assembly 20 transmits the pressure change to the user, so that the user generates an operational feeling during shifting.

In addition, when the abutting member 43 moves to the top of the bottom of the shift slot 31 and the abutting member 43 continues to move along the top of the bottom of the shift slot 31 to the second end of the shift slot 31, the user can apply no external force to the shift lever assembly 20, and at this time, the compression amount of the first elastic member 42 starts to decrease because the compression force applied by the abutting member 43 to the first elastic member 42 starts to decrease. As the amount of compression of the first elastic member 42 begins to decrease, the first elastic member 42 begins to elongate. As the external force applied by the user disappears, the first elastic element 42 can push the abutting element 43 to slide on the bottom of the shift slot 31 until the abutting element 43 slides to the second end of the shift slot 31. That is, when the abutting member 43 moves to the top of the bottom of the shift slot 31 and the abutting member 43 continues to move along the top of the bottom of the shift slot 31 to the second end of the shift slot 31, the user can apply no external force to the shift lever assembly 20, and the abutting member 43 can continue to slide in the shift slot 31 by the elastic force of the first elastic member 42. Of course, when the holding member 43 moves to the top of the bottom of the shift groove 31 and the holding member 43 continues to move along the top of the bottom of the shift groove 31 to the second end of the shift groove 31, the user can continue to apply an external force to the shift lever assembly 20, and at this time, the first elastic member 42 and the external force applied by the user simultaneously act on the holding member 43, so that the holding member 43 moves along the top of the bottom of the shift groove 31 to the second end of the shift groove 31.

In addition, when the abutting member 43 slides to the second end of the shift slot 31, since the middle portion of the shift slot 31 protrudes toward the direction of the notch, the compression amount of the first elastic member 42 does not change in the absence of an external force, at this time, the first elastic member 42 cannot push the abutting member 43 by its own elastic force, and further, after the abutting member 43 slides to the second end of the shift slot 31, the abutting member 43 does not continue to slide, so that the abutting member 43 is prevented from moving to the middle portion of the shift slot 31 along the second end of the shift slot 31 under the elastic force of the first elastic member 42.

Normally, when the holding member 43 moves towards the middle of the gearshift slot 31 along the first end of the gearshift slot 31, indicating that the user is shifting gears, since the middle of the gearshift slot 31 protrudes towards the direction of the notch, and after the holding member 43 slides to the second end of the gearshift slot 31, the holding member 43 cannot move towards the middle of the gearshift slot 31 along the second end of the gearshift slot 31 under the elastic force of the first elastic member 42, therefore, after the user selects a certain gear, the gear can be fixed, and the situation that the holding member 43 jumps due to the elastic force of the first elastic member 42 when no external force is applied is avoided. Here, the trip refers to a state in which the holder 43 is automatically moved from one shift groove 31 to another shift groove 31 without an external force, so that the shift position is changed.

For example, the user applies an external force to the shift lever assembly 20, so that the holding part 43 is located in the shift groove 31 of the 3 th gear, and the shift position is the 3 rd gear. At this time, the abutting member 43 is located at the second end of the 3 rd shift gate 31. Under the condition of no external force, the holding piece 43 cannot slide along the shifting groove 31 of the 3-gear under the action of the elastic force of the first elastic piece 42, so that the holding piece 43 is prevented from sliding from the shifting groove 31 of the 3-gear to the shifting grooves 31 of other gears, and the problem of gear jumping can be avoided.

Additionally, in some embodiments, as shown in fig. 10, the shift mechanism may further include a control assembly 50. The control assembly 50 is disposed on the base 10, and the control assembly 50 is connected to the shift lever assembly 20, and the control assembly 50 is configured to obtain a swing angle of the shift lever assembly 20 and determine gear information according to the swing angle of the shift lever assembly 20.

During the rotation of the shift lever assembly 20, the shift lever assembly 20 can swing to different angles, and since the control assembly 50 is connected to the shift lever assembly 20, the control assembly 50 can acquire the swing angle of the shift lever assembly 20 and determine the gear information according to the swing angle of the shift lever assembly 20.

It should be noted that, when the telescopic structure 40 is disposed on the shift lever assembly 20, during the rotation of the shift lever assembly, the shift lever assembly 20 can drive the telescopic structure 40 to move in the shift slot 32 or the shift slot 31 of the shift lever assembly 30, and when the swing angles of the shift lever assembly 20 are different, the telescopic structure 40 may be located in different shift slots 31, and at this time, the control assembly 50 can determine the shift information according to the swing angle of the shift lever assembly 20.

In addition, in the embodiment of the present application, the gear information may include gear selection information, and as shown in fig. 10, the control assembly 50 may include a control body 51 and a positioning arm 52. The control body 51 is movably connected with the positioning arm 52, the positioning arm 52 is provided with a positioning groove extending along the left-right direction, the shift lever assembly 20 can swing along the left-right direction, and when the shift lever assembly 20 swings along the left-right direction, at least part of the shift lever assembly 20 slides in the positioning groove. The positioning arm 52 is provided therein with a hall element electrically connected to the control body 51, the hall element is configured to detect a swing angle of the shift lever assembly 20 swinging in the left-right direction, and transmit a first swing angle to the control body 51, and the control body 51 determines gear selection information according to the first swing angle.

Since the positioning groove is formed in the positioning arm 52, the shift lever assembly 20 can swing in the left-right direction, and at least a portion of the shift lever assembly 20 slides in the positioning groove when the shift lever assembly 20 swings in the left-right direction, so that the shift lever assembly 20 can have different swing angles when the shift lever assembly 20 swings in the left-right direction. Since the hall element is disposed in the positioning arm 52, the hall element can detect the first swing angle of the shift lever assembly 20 swinging in the left-right direction, and then the hall element transmits the first swing angle to the control body 51, so that the control body 51 can determine the gear selection information according to the first swing angle.

It should be noted that the telescoping structure 40 provided on the shift lever assembly 20 can be positioned in the shift gate 32 during the swinging of the shift lever assembly 20. Since the selector groove 32 communicates with the shift groove 31, when the telescopic structure 40 is positioned differently in the selector groove 32, the corresponding shift groove 31 is also different. The position of the telescopic structure 40 in the gear selecting slot 32 changes because the gear shift lever assembly 20 swings to drive the telescopic structure 40 to move in the gear selecting slot 32, so that the telescopic structure 40 can be located in different positions in the gear selecting slot 32 by swinging the gear shift lever assembly 20 by different angles, and further the telescopic structure 40 can enter different gear shifting slots 31.

In addition, the positioning groove extending in the left-right direction on the positioning arm 52 in the embodiment of the present application may be a groove or a through groove, and when the positioning groove is a groove, the shift lever assembly 20 may be partially inserted into the groove, so that the shift lever assembly 20 is connected with the positioning groove. When the detent is a through slot, the lever assembly 20 may partially pass through the through slot such that the lever assembly 20 is connected with the detent. The type of the positioning slot formed on the positioning arm 52 is not limited in the embodiment of the present application.

In addition, since the shift lever assembly 20 can swing in the positioning groove, and the positioning arm 52 is provided with the hall element, the principle of the hall element is that the conductors cut different magnetic induction lines in the magnetic field to generate different currents, and in the process of swinging the shift lever assembly 20 in the left-right direction, the swinging angle of the shift lever assembly 20 is different, and the conductors cut the magnetic induction lines to generate different currents, the hall element can determine the first swinging angle of the shift lever assembly 20 according to the currents, and transmit the first swinging angle of the shift lever assembly 20 to the control body 51.

When the shift lever assembly 20 swings in the positioning groove in the left-right direction, when the swinging first swing angles are different, the telescopic structure 40 can enter different shift grooves 31 in the shift selection groove 32, and then which shift position is selected can be determined, and the hall element can determine the swinging first swing angle of the shift lever assembly 20 according to the current, so that the swinging first swing angle of the shift lever assembly 20 around the left-right direction corresponds to the shift selection information, and further the control body 51 can determine the shift selection information according to the swinging first swing angle of the shift lever assembly 20 along the left-right direction, so that when the control body 51 acquires the swinging first swing angle of the shift lever assembly 20, the control body 51 can determine the shift selection information according to the swinging first swing angle. The gear selection information indicates the gear corresponding to the selected shift groove 31. For example, when the first swing angle of the shift lever assembly 20 is 10 degrees, the telescopic structure 40 can enter the 3-gear shift notch, indicating that the 3-gear shift is selected.

Additionally, in some embodiments, the gear information may also include shift information, and the control assembly 50 may include a control body 51, a positioning arm 52, and an angle sensor. The positioning arm 52 is movably connected to the control body 51 in a front-rear direction, the shift lever assembly 20 is connected to the positioning arm 52, the shift lever assembly 20 is capable of swinging in a front-rear direction, and the positioning arm 52 is driven to swing in a front-rear direction when the shift lever assembly 20 swings in the front-rear direction. The angle sensor is connected to the control body 51, and is configured to detect a second swing angle at which the positioning arm 52 swings in the front-rear direction, and transmit the second swing angle to the control body 51, and the control body 51 determines shift information according to the second swing angle.

Since the positioning arm 52 is movably connected to the control body 51 in a forward-backward direction, and the shift lever assembly 20 is connected to the positioning arm 52, when the shift lever assembly 20 swings in the forward-backward direction, the shift lever assembly 20 can drive the positioning arm 52 to swing, and at this time, the second angle of swing of the positioning arm 52 corresponds to the angle of swing of the shift lever assembly 20 in the forward-backward direction. Since the control body 51 is connected to the angle sensor, the angle sensor can determine the second swing angle at which the positioning arm 52 swings, and thus the angle at which the shift lever assembly 20 swings in the front-rear direction. In addition, when the shift lever assembly 20 swings in the front-back direction, the telescopic structure 40 on the shift lever assembly 20 enters the shift groove 31 to realize shifting, which is equivalent to that the swing angle of the shift lever assembly 20 in the front-back direction corresponds to the shift groove 31 into which the telescopic structure 40 enters, so that after the swing angle of the shift lever assembly 20 in the front-back direction is determined, the second swing angle of the positioning arm 52 can be determined, and further, which shift groove 31 the telescopic structure 40 enters can be determined according to the second swing angle of the positioning arm 52, therefore, the control body 51 can determine the shifting information after acquiring the second swing angle of the positioning arm 52 in the front-back direction. The shift information refers to the gear corresponding to the shift groove 31 in which the telescopic structure 40 is located. For example, when the telescopic structure 40 is located in the shift gate 31 of the 3 rd gear, this indicates that the gear after the shift is the 3 rd gear.

Since the middle portion of the groove bottom of the shift groove 31 protrudes in the direction of the notch, when the shift lever assembly 20 slides to the apex of the groove bottom of the shift groove 31, a problem of disengagement of the shift lever assembly 20 from the shift groove 31 may occur, and in order to avoid such a problem, in some embodiments, the middle portion of the groove wall of the shift groove 31 protrudes in the opening direction of the notch.

When the middle part of the groove wall at the bottom of the shift groove 31 protrudes along the opening direction of the notch, when the shift lever assembly 20 slides to the top point of the groove bottom, at the moment, the top point of the groove wall is also corresponding to the top point of the groove bottom, therefore, the groove wall can still play a role in blocking the shift lever assembly 20, and the problem that the shift lever assembly 20 possibly breaks away from the shift groove 31 at the top point of the groove bottom is avoided. In the embodiment of the present application, the shape of the groove bottom of the shift groove 31 may be the same as the shape of the groove wall of the shift groove 31, but of course, may also be different, and the embodiment of the present application is not limited herein.

It should be noted that, when the telescopic structure 40 is disposed on the shift lever assembly 20, at this time, the middle portion of the groove wall of the shift groove 31 protrudes along the opening direction of the notch, so that the problem that the abutting piece 43 in the telescopic structure 40 is separated from the shift groove 31 at the vertex of the groove bottom when sliding to the vertex of the shift groove 31 can be avoided.

Additionally, in some embodiments, as shown in fig. 10 and 14, the shift mechanism further includes a cable 100, the cable 100 is adapted to be connected with a speed reducer, and the shift lever assembly 20 may include a shift lever 21, a first swing arm 22, and a second swing arm 23. One end of the first swing arm 22 and one end of the second swing arm 23 are connected to one end of the shift lever 21, respectively. The cable 100 includes that the selection keeps off the cable and shift gears the cable, and the other end and the selection of first swing arm 22 keep off the cable and be connected, and the other end and the shift gears cable of second swing arm 23 are connected.

When the shift lever assembly 20 includes a shift lever 21, a first swing arm 22 and a second swing arm 23. One end of the first swing arm 22 and one end of the second swing arm 23 are respectively connected to one end of the shift lever 21, so that the shift lever 21 can drive the first swing arm 22 and the second swing arm 23 to move. Because the cable 100 includes the selection and keeps off the cable and the cable of shifting gears, the other end and the selection of first swing arm 22 keep off the cable and be connected, the other end and the cable of shifting gears of second swing arm 23 are connected, and at the in-process that first swing arm 22 and second swing arm 23 removed, first swing arm 22 and second swing arm 23 can drive respectively and select to keep off the cable and shift gears the cable and remove to the realization is shifted gears and is kept off with selecting. In addition, the cable 100 is usually connected to the decelerator 100 in the vehicle, and therefore, the first and

second swing arms

22 and 23 can also adjust the decelerator 100 through the gear selection cable and the gear shift cable during the movement of the first and

second swing arms

22 and 23.

It should be noted that, in the embodiment of the present application, when the speed reducer included in the vehicle is a push rod type speed reducer, at this time, the other end of the first swing arm 22 and the other end of the second swing arm 23 may both be connected to the speed reducer through a push rod, so as to implement gear selection and gear shifting operations of the speed reducer.

In addition, in the embodiment of the present application, when the shift lever assembly 20 includes the shift lever 21, the first swing arm 22 and the second swing arm 23, at this time, the telescopic structure 40 may be disposed on the first swing arm 22, that is, the fixing sleeve 41 in the telescopic structure 40 may be fixed on the first swing arm 22.

In addition, in some embodiments, the gear shifting mechanism further comprises a cable 100, the cable 100 is suitable for being connected with a speed reducer, and the gear assembly 30 can be slidably connected with the base 10. In the case that the gear assembly 30 slides to the first position of the base 10, the shifting force is generated by the pressure with the gear assembly 30 when the shift lever assembly 20 swings. When the shift lever assembly 20 swings, the shift lever assembly 30 slides to the second position of the base 10, and the cable 100 is connected to the speed reducer to generate a shifting force.

Since gear assembly 30 is slidably coupled to base 10, gear assembly 30 can slide on base 10. Since the shifting force is generated by the pressure between the gear assembly 30 when the gear assembly 30 slides to the first position of the base 10 and the shifting force is generated by the connection between the cable 100 and the speed reducer when the gear assembly 20 swings and the shifting force is generated by the connection between the cable 100 and the speed reducer when the gear assembly 30 slides to the second position of the base 10, the shifting mechanism provided by the embodiment of the present application has two modes, and the shifting between the two modes can be realized by the gear assembly 30. The first mode may be a mode corresponding to the gear assembly sliding to the first position, and the second mode may be a mode corresponding to the gear assembly 30 sliding to the second position. That is, by slidably coupling the gear assembly 30 to the base 10, the gear shift mechanism can have two modes, which makes the gear shift mechanism more widely applicable.

In addition, in the embodiment of the present application, when the gear assembly 30 slides to the first position of the base 10, the shift lever assembly 20 can abut against the gear assembly 30, and the shift lever assembly 20 abuts against the gear assembly 30, which means that the shift lever assembly 20 abuts against the gear assembly 30, and the pressure is greater than the pressure threshold, at which point the shift lever assembly 20 may be in contact with the gear assembly 30 and the shift lever assembly 20 exerts a pressure on the gear assembly 30 that is greater than the pressure threshold. As shown in fig. 11, when the gear assembly 30 slides to the second position of the base 10, the shift lever assembly 20 can be disengaged from the gear assembly 30, and the shift lever assembly 20 is disengaged from the gear assembly 30, which means that the shift lever assembly 20 generates pressure or does not generate pressure on the gear assembly 30, and when the pressure is generated, the pressure is smaller than a pressure threshold value, and at this time, the shift lever assembly 20 can be in contact with the gear assembly 30, and the generated pressure is smaller than the pressure threshold value, or the shift lever assembly 20 is separated from the gear assembly 30. The pressure threshold may be determined according to actual needs, that is, may be determined according to an operation feeling that a user may feel when operating the shift lever assembly 20, and as to a value of the pressure threshold, the embodiment of the present application is not limited herein _。

It should be noted that, in the embodiment of the present application, the first swing arm 22 and the second swing arm 23 are connected to the cable 100 regardless of whether the gear assembly 30 is located at the first position or the second position. When the gear assembly 30 is in the first position, the cable 100 may be in a slack state and no shifting force is generated, in which case the shift lever assembly 20 generates a shifting force by pressure between the shift lever assembly 20 and the gear assembly 30, and when the gear assembly 30 is in the second position, the cable 100 may be in a taut state and the shift lever assembly 20 generates a shifting force by connection with the cable 100. Of course, when the shift unit 30 is located at the first position, the cable 100 may also be in a tight state, and in this case, the shift lever unit 20 may generate a shifting force not only by a pressure between the shift lever unit 20 and the shift unit 30, but also by a connection with the cable 100, which is not limited herein.

In addition, generally, the cable 100 is connected to the decelerator 100 in the vehicle, and when the cable 100 is in a tight state, the cable 100 may actually generate a shifting force through the decelerator 100.

In addition, in the present embodiment, the first position of the gear assembly 30 is a position close to the shift lever assembly 20 compared to the second position, which is a position away from the shift lever assembly 20.

Of course, a lubricant may also be provided in the slide groove 11 to facilitate the sliding of the boss 33 in the slide groove 11.

When the gear assembly 30 is moved away from the fixed plate 12, the second elastic element 34 can be extended. When the second elastic member 34 is extended, the second elastic member 34 can be held against the fixed plate 12 at one end to provide an elastic force to the gear assembly 30, so as to facilitate the sliding of the gear assembly 30.

When the gear assembly 30 slides away from the fixed plate 12, at this time, the sliding rod 302 can move in the second direction, so that the distance between the gear assembly 30 and the fixed plate 12 becomes gradually larger, at this time, the second elastic member 34 starts to extend, and the second elastic member 34 can apply an elastic force to the gear assembly 30, so that the gear assembly 30 becomes gradually away from the fixed plate 12.

In addition, since the second elastic member 34 is nested on the sliding rod 302, the sliding rod 302 can provide a supporting force for the second elastic member 34 during the extension or compression of the second elastic member 34, so as to prevent the position of the second elastic member 34 from being deviated. In addition, during the sliding of the gear assembly 30, since one end of the sliding rod 302 is located in the sliding hole, the sliding rod 302 can also guide the gear assembly 30.

The working principle of the gear shifting mechanism provided by the embodiment of the present application is specifically described below with reference to fig. 1 to 13:

as shown in fig. 1 to 13, in the embodiment of the present application, when a first signal, that is, an analog shift signal, is received, at this time, the control assembly 50 may control the driving member 61 to operate, the driving member 61 drives the rotating shaft 621 to rotate in a forward direction, that is, the driving boss 63 faces a direction in which the gear assembly 30 rotates, the rotating shaft 621 drives the drum 62 to rotate in a forward direction, the drum 62 drives the driving boss 63 to rotate, and then the driving boss 63 applies pressure to the gear assembly 30, so that the bosses 33 on both sides of the gear assembly 30 slide in the sliding grooves 11 on the first mounting plate 13 and the second mounting plate 14, respectively, and thus the gear assembly 30 can slide between the first mounting plate 13 and the second mounting plate 14. When the driving boss 63 can be in the first state, the gear assembly 30 slides to the first position, and the driving member 61 is locked inside. In addition, the abutment 43 in the shift lever assembly 20 compresses the first resilient member 42 such that the first resilient member 42 is compressed and the abutment 43 abuts against the bottom of the shift groove 31 on the gear assembly 30. The second resilient member 34 on the sliding bar 302 of the gear assembly 30 is in a compressed state. Since the driving member 61 is locked inside, the gear assembly 30 cannot move under the action of the second elastic member 34, i.e. the position of the gear assembly 30 is fixed by the driving boss 63 and the driving member 61. Since the first elastic member 42 is compressed, the first elastic member 42 can apply an elastic force to the fixed sleeve 41 and the first swing arm 22, so that the abutting member 43 abuts against the shift groove 31 on the gear assembly 30, when the shift lever 21 drives the first swing arm 22 to move, the telescopic structure 40 slides in the shift groove 31, and the middle of the groove bottom of the shift groove 31 protrudes toward the groove opening, so that when shifting is performed by the shift lever 21, a variable shifting force can be generated. In some embodiments, the drive boss 63 may be in a horizontal state when the drive boss 63 is in the first state.

When a second signal, that is, a mechanical shift signal is received, at this time, the control assembly 50 may control the driving member 61 to operate, the driving member 61 drives the rotating shaft 621 to rotate in the opposite direction, that is, the driving boss 63 is away from the direction in which the gear assembly 30 rotates, the drum 62 drives the driving boss 63 to rotate, the rotating boss 33 gradually changes from the first state to the second state, the first elastic member 42 in the telescopic structure 40 on the first swing arm 22 gradually extends, and the second elastic member 34 on the sliding rod 302 on the gear assembly 30 gradually extends, and the second elastic member 34 applies an elastic force to the gear assembly 30, so that the bosses 33 on both sides of the gear assembly 30 respectively slide in the sliding grooves 11 on the first mounting plate 13 and the second mounting plate 14, and the gear assembly 30 can slide between the first mounting plate 13 and the second mounting plate 14. When the gear assembly 30 is slid to the second position, the driving boss 63 can be in the vertical state and the driving member 61 is locked inside. In addition, the first elastic member 42 in the telescopic structure 40 on the shift lever assembly 20 is extended and applies elastic force to the abutting member 43, so that the abutting member 43 is partially embedded in the fixing sleeve 41. The second elastic element 34 of the sliding rod 302 of the gear unit 30 is in the extended state and the abutment 43 no longer abuts against the bottom of the shift groove 31 of the gear unit 30 but is partly located in the shift groove 31. Since the interior of the driving member 61 is locked and the driving boss 63 is in contact with the gear assembly 30, the driving boss 63 can apply resistance to the gear assembly 30, so that the gear assembly 30 cannot move under the action of the second elastic member 34, i.e. the position of the gear assembly 30 is fixed by the driving boss 63 and the driving member 61. Because first swing arm 22 and second swing arm 23 are connected with gear selection cable and the cable of shifting in the vehicle respectively, at this moment, when shifting through gear level 21, gear level 21 can drive first swing arm 22 and second swing arm 23 and remove, and first swing arm 22 and second swing arm 23 drive gear selection cable and the cable of shifting and remove for gear level subassembly 20 can produce the power of shifting. In some embodiments, the drive boss 63 may be in a vertical position when the drive boss 63 is in the second position.

In addition, in the embodiment of the present application, the driving member 61 and the control body 51 may be fixed to the base 10 by bolts.

In addition, in the embodiment of the present application, when the shifting mechanism is installed in different vehicles, the control assembly 50 can control the driving assembly 60 to drive the gear assembly 30 to slide to the first position according to the actual structure of different vehicles, and the distance between the gear assembly 30 and the fixed plate 12 is different, i.e. the pressure between the gear assembly 30 and the shifting lever assembly 20 is different, so that the shifting lever assembly 20 can generate the shifting force suitable for the user.

As shown in fig. 14, the vehicle includes a speed reducer 200 and a shift mechanism in any of the embodiments described above.

In addition, in this embodiment of the application, a console may be disposed in the vehicle, a switch button is disposed on the console, the switch button may switch between two modes, a mechanical shift mode and an analog shift signal mode, and the switch button is used to send a switch instruction to a vehicle control unit in the vehicle, so that the vehicle control unit may send a signal to a control component 50 in the shift mechanism, so that the control component 50 receives a mechanical shift signal or an analog shift signal.
