[0002] See also Figure 1 The gear lever type shifting device generally includes a handle member 11, a gear lever member 13 and a main body member 12. In the related art, the gear lever member includes an upper connecting rod and a lower connecting rod. At least one of the upper connecting rod and the lower connecting rod is provided with a long slide groove extending along the length direction of the gear lever member. The upper connecting rod and the lower connecting rod are fastened and connected by bolts and nuts at the position corresponding to the long slide groove. By loosening the nut, the upper connecting rod and the lower connecting rod can be adjusted to move relative to each other along the length direction to change the overall length of the gear lever member, thereby realizing the adjustment of the position of the handle member in the height direction. By locking the nut, the position of the handle member can be fixed. However, this method of adjusting the position of the handle member in the height direction in the related art is relatively cumbersome to operate and very inconvenient to use. Utility Model Content

[0086] Hereinafter, specific embodiments of the present invention will be described in more detail with reference to the accompanying drawings. These drawings show representative embodiments of the present invention and are not intended to limit the present invention.

[0087] The utility model provides a shift assembly, a shift device and a vehicle. The shift assembly here can be understood as a gear lever type shift assembly. The gear lever type shift assembly includes a traditional gear shift assembly using mechanical transmission, and can also include an electronically controlled gear shift assembly used in pure electric vehicles. The shift device, based on the shift assembly, also includes structures such as a shielding cover to hide the handle components of the idle shift assembly. The vehicle here can be any vehicle that needs to use a gear lever type shift device, such as a traditional fuel vehicle, a hybrid vehicle, an extended-range vehicle, a pure electric vehicle, etc.

[0088] See below Figures 2 to 9 The shift assembly, the shift device and the vehicle according to the utility model are described in detail.

[0089] According to the shift assembly of the utility model, it may include a handle member 111, a main body member 112, a shift rod member 113 and a transmission member 120. The shift rod member 113 may include a first rod 114 and a second rod 115. The first rod 114 is connected to the handle member 111. The second rod 115 is connected to the main body member 112. The first rod 114 is movably arranged relative to the second rod 115 along the length direction D2 to change the size of the shift rod member 113 along the length direction D2. In the installation state of the shift assembly 110 of the utility model installed to the vehicle, the length direction D2 may be parallel to the height direction of the vehicle or nearly parallel to the height direction of the vehicle. The transmission member 120 is movably arranged relative to the second rod 115. And the transmission member 120 is fixedly arranged relative to the second rod 115 in the length direction D2. The transmission member 120 is transmission-connected to the first rod 114 to apply a force along the length direction D2 to the first rod 114 , so that the first rod 114 moves relative to the second rod 115 along the length direction D2 .

[0090] According to the shift assembly 110 of the utility model, by setting the shift rod member 113 as two parts, the first rod 114 and the second rod 115, the first rod 114 can move relative to the second rod 115 in the length direction D2, thereby changing the size of the shift rod member 113 in the length direction D2. Since the handle member 111 is connected to the first rod 114, and the second rod 115 is connected to the main body member 112, the position of the handle member 111 relative to the main body member 112 in the length direction D2 can be changed. By setting the transmission member 120, a force can be applied to the first rod 114 along the length direction D2, so that the first rod 114 can move relative to the second rod 115. In the process of adjusting the size of the shift rod member 113 along the length direction D2, there is no need to use manual operation, the operation method is more simplified, and the operation process is more labor-saving and convenient.

[0091] See also Figures 4 to 9For example, the lower end of the first rod 114 has a guide protrusion 114a. The transmission member 120 may include a rotating cylinder 121. The rotating cylinder 121 is rotatably arranged around the rotation axis AX relative to the second rod 115. The rotating cylinder 121 may include a vacant portion 121a suitable for inserting the guide protrusion 114a.

[0092] The rotating drum 121 may be configured such that:

[0093] During the rotation about the rotation axis AX, a force along the length direction D2 is applied to the guide protrusion 114 a located at the vacant portion 121 a , so that the first rod 114 moves along the length direction D2 along with the guide protrusion 114 a .

[0094] Here, the rotational movement of the rotating cylinder 121 is converted into the movement of the first rod 114 in the length direction D2 through the matching relationship between the vacant portion 121a and the guide protrusion 114a, thereby changing the position of the handle member 111 in the length direction D2.

[0095] Further, the guide protrusion 114a is extended along a direction intersecting, for example, perpendicular to the length direction D2. The rotation axis AX is parallel to the length direction D2. The vacancy 121a has a first end and a second end spaced apart along the length direction D2, and in the circumferential direction with the rotation axis AX as the center line, the first end and the second end of the vacancy 121a are spaced apart. Take the first end closer to the handle member 111 as an example. When the guide protrusion 114a is located at the first end of the vacancy 121a, the length of the lever member 113 is longer. When the guide protrusion 114a is located at the second end of the vacancy 121a, the length of the lever member 113 is shorter. In other words, the vacancy 121a is at least partially extended along the circumferential direction and the length direction D2. The vacancy 121a here can be understood as a cam groove, or the vacancy 121a can be understood as a part of a slot cam.

[0096] Optionally, when the rotating drum 121 is configured as a rotating body structure, the axis of the rotating drum 121 may be parallel to or coincide with the rotation axis.

[0097] Continue reading Figures 4 to 9 In addition, the shift assembly 110 may further include a connecting member 116. The connecting member 116 is connected to the second rod 115. The connecting member 116 is provided with a guide hole 117b. The guide holes 117b are all extended along the length direction D2. The guide holes 117b are suitable for passing the guide protrusions 114a through to guide the guide protrusions 114a to move along the length direction D2. Through the matching relationship between the guide holes 117b of the connecting member 116 and the guide protrusions 114a at the end of the first rod 114, the first rod 114 is guided to move in the length direction D2.

[0098] The shifting device according to the utility model may include a shielding cover 100 and a shifting assembly 110. A receiving chamber 101b is formed inside the shielding cover 100. An opening 101a connected to the receiving chamber 101b is provided at the top of the shielding cover 100. The shifting assembly 110 may include a handle member 111, a main member 112 and a shifting rod member 113. The handle member 111 is arranged corresponding to the opening 101a along the length direction D2. The main member 112 is fixedly arranged in the receiving chamber 101b along the length direction D2 of the shifting rod member 113 relative to the shielding cover 100. The main member 112 here can be understood as a transmission structure that generates a shifting action according to the action of the shifting rod member 113 or an electronic device that generates a shifting trigger signal. The shifting rod member 113 may include a first rod 114 and a second rod 115. The first rod 114 is connected to the handle member 111. The second rod 115 is connected to the main member 112. The first rod 114 is movably arranged relative to the second rod 115 along the length direction D2, so that the handle member 111 can move between the extended position and the storage position. When the handle member 111 is in the extended position, the handle member 111 extends out of the opening 101a and protrudes from the outer surface of the shielding cover 100. When the handle member 111 is in the storage position, the handle member 111 is located in the accommodating cavity 101b, and the shielding cover 100 is used to surround the handle member 111 to shield the handle member 111.

[0099] According to the shifting device of the present invention, the main body member 112 is fixedly arranged relative to the shielding cover 100 in the length direction D2, and the first rod 114 can move relative to the second rod 115 along the length direction D2. In this way, not only can the position of the handle member 111 in the length direction D2 be adjusted, but also the handle member 111 can be moved to the storage position when it is not needed, so that the handle member 111 can be stored by the shielding cover 100, thereby reducing the space occupied by the handle member 111 when it is not idle.

[0100] See also Figures 4 to 9For example, the lower end of the first rod 114 has a guide protrusion 114a. The guide protrusion 114a extends in a direction perpendicular to the length direction D2. The shift assembly 110 may also include a connecting member 116 and a rotating cylinder 121. The connecting member 116 is connected to the second rod 115. The connecting member 116 is provided with a guide hole 117b. The guide holes 117b are all extended in the length direction D2. The guide holes 117b are suitable for passing the guide protrusion 114a. The rotating cylinder 121 is rotatably arranged around the rotation axis AX relative to the connecting member 116. The rotation axis AX is parallel to the length direction D2. The rotating cylinder 121 may include a vacant portion 121a suitable for inserting the guide protrusion 114a. The vacant portion 121a is spirally extended along the length direction D2. By the cooperation of the guide protrusion 114a and the guide hole 117b, the movable direction of the first rod 114 can be limited to the length direction D2, and the movement of the first rod 114 can be guided during the movement of the first rod 114. By providing a rotating cylinder 121 that rotates around the rotation axis AX and utilizing the cooperation of the guide protrusion 114a and the vacant portion 121a, a force along the length direction D2 can be applied to the guide protrusion 114a during the rotation of the rotating cylinder 121, so that the guide protrusion 114a can move along the length direction D2.

[0101] Optionally, the guide protrusion 114 a may be fixedly connected to the end of the first rod 114 away from the handle member 111 in the length direction D2 , or may be manufactured as an integral piece with the first rod 114 .

[0102] Continue reading Figures 4 to 9, further, the connecting member 116 may include a connecting tube 117 and a connecting seat 118. The connecting tube 117 is extended along the length direction D2. The side wall of the connecting tube 117 is provided with a guide hole 117b in a radial direction. The guide hole 117b is extended along the length direction D2 in the connecting tube 117. The connecting tube 117 has an inner hole 117a, and the lower end of the first rod 114 is inserted into the inner hole 117a. The connecting tube 117 is sleeved on the outside of the first rod 114. The connecting seat 118 is connected to the lower part of the connecting tube 117. The connecting seat 118 is connected to the second rod 115. The rotating tube 121 is sleeved on the outside of the connecting tube 117. Here, the first rod 114 is installed through the connecting tube 117 of the connecting member 116, and the connecting tube 117 surrounds the outside of the lower end of the first rod 114. The connecting cylinder 117 can better constrain the first rod 114 in the radial direction, and also has a certain guiding effect on the rod body of the first rod 114 in the length direction D2. Combined with the guide hole 117b set in the connecting cylinder 117, it can better guide the moving direction of the first rod 114 in the length direction D2. By sleeve-arranging the rotating cylinder 121 on the outside of the connecting cylinder 117, it is convenient to arrange the relevant transmission structure to realize the transmission of power to the rotating cylinder 121. The connecting member 116 is installed on the second rod 115 by connecting the connecting seat 118 to the second rod 115.

[0103] See also Figure 6 , Figure 8 and Fig. 9 Furthermore, the first rod 114 is provided with guide protrusions 114a on both opposite sides in the radial direction. Correspondingly, the connecting cylinder 117 is provided with guide holes 117b symmetrically on both opposite sides. The rotating cylinder 121 is provided with two vacant portions 121a, and the two vacant portions 121a are centrally symmetrically distributed about the axis of the rotating cylinder 121. In this way, the force balance of the first rod 114 can be improved to reduce the probability of jamming.

[0104] In other examples not shown, the rotating cylinder 121 may also be located inside the connecting cylinder 117. For example, the rotating cylinder 121 is located radially between the connecting cylinder 117 and the first rod 114. Alternatively, when the lower end of the first rod 114 is a hollow structure, the lower end of the first rod 114 may be sleeved outside the rotating cylinder 121.

[0105] See also Figure 4 , Figure 6 and Figure 7 Optionally, the connection seat 118 can be detachably mounted on the upper portion of the second rod by means of snap connection, screw connection, etc. For example, a mounting hole can be provided at the lower portion of the connection seat 118, the upper portion of the second rod 115 can be inserted into the mounting hole, and then the connection seat 118 and the upper portion of the second rod 115 can be snapped together by means of a retaining spring.

[0106] See also Figures 4 to 7 In addition, the connecting member 116 may further include a stopper 119. The stopper 119 is connected to the upper portion of the connecting cylinder 117. The rotating cylinder 121 is limitedly fitted between the stopper 119 and the connecting seat 118 along the length direction D2. By providing the stopper 119, the rotating cylinder 121 can be prevented from moving upward, thereby ensuring that the rotating cylinder 121 can effectively convert the rotational motion into the linear motion of the first rod 114 along the length direction D2.

[0107] For example, the stopper 119 is installed to the connecting tube 117 in a detachable connection manner such as a threaded connection. This makes it easy to disassemble and assemble the stopper 119, and is also convenient for replacing parts and reducing maintenance costs.

[0108] Optionally, the stopper 119 is a ring-shaped member. The stopper 119 has an internal thread, and the upper portion of the connecting tube 117 is provided with an external thread. The stopper 119 is screwed to the upper portion of the connecting tube 117.

[0109] See also Figure 6 and Figure 8 For example, the vacant portion 121a may include a spiral portion 121b and a positioning portion 121c. One end of the positioning portion 121c is connected to the upper end of the spiral portion 121b. The plane where the positioning portion 121c is located is perpendicular to the length direction D2 to prevent the guide protrusion 114a from moving downward. During the rotation of the rotating cylinder 121, the physical structure of the rotating cylinder 121 in the spiral portion 121b can be used to apply a force along the length direction D2 to the guide protrusion 114a, thereby driving the first rod 114 to move up or down. When the rotating cylinder 121 rotates in one direction and makes the guide protrusion 114a in the positioning portion 121c, the first rod 114 is lifted to the highest position. At the same time, the positioning portion 121c is used to reliably support and limit the guide protrusion 114a, thereby preventing the guide protrusion 114a from moving downward under the weight of the first rod 114 or the force of external misoperation. When the guide protrusion 114a at the lower end of the first rod 114 slides to the positioning portion 121c at the upper end of the rotating cylinder 121, it will be firmly fixed at this position. At this time, the user can perform a gear shift operation through the handle member 111.

[0110] exist Figure 8 In the example shown, the vacant portion 121 a is a through hole penetrating into the inner cavity of the rotating cylinder 121 .

[0111] Those skilled in the art can understand that, in some cases, the plane where the positioning portion 121c is located is not completely perpendicular to the length direction D2, such as being nearly perpendicular to the length direction D2, which can also prevent the guide protrusion 114a from moving downward.

[0112] See also Figures 4 to 6In addition, the shift assembly 110 may also include a meshing worm 122 and a worm wheel 123 and a first motor 124. The worm wheel 123 is fixedly connected to the rotating cylinder 121. The axis of the worm wheel 123 coincides with the rotation axis AX. The output shaft of the first motor 124 is connected to the worm 122 to drive the worm 122 to rotate, and then through the cooperation of the worm 122 and the worm wheel 123, the power is transmitted to the rotating cylinder 121, and the rotating cylinder 121 is indirectly driven to rotate. The worm 122 and the worm wheel 123 here and the above-mentioned rotating cylinder 121 can be understood as the transmission component 120 of the shift assembly 110, which is used to transmit power between a driving member such as the first motor 124 and the first rod 114, so that the first rod 114 can move along the length direction D2.

[0113] For example, the lead angle of the worm 122 is smaller than the equivalent friction angle between the worm 122 and the worm wheel 123. In this way, the worm 122 and the worm wheel 123 have a certain self-locking property, so that when the first rod 114 is subjected to a downward force along the length direction D2, the worm wheel 123 can be effectively prevented from rotating through the cooperation of the worm 122 and the worm wheel 123.

[0114] See also Figure 7 Further, the upper part of the above-mentioned connecting seat 118 is provided with a first mounting portion 118a and a second mounting portion 118b. The first mounting portion 118a is suitable for mounting the first motor 124. The second mounting portion 118b is suitable for mounting the worm 122. In this way, the first motor 124 and the worm 122 are supported and assembled by the connecting seat 118.

[0115] Optionally, the first mounting portion 118 a may be configured to be adapted to fit in a mounting groove for accommodating the first motor 124 . The second mounting portion 118 b may be configured to be adapted to fit in another mounting groove for accommodating the worm 122 .

[0116] Furthermore, the worm gear 123 can be detachably mounted to the rotating drum 121. The worm gear 123 can also be fixed to the rotating drum 121 or made into an integral part with the rotating drum 121.

[0117] It is understood that in some other embodiments, the meshing worm 122 and the worm wheel 123 may be replaced by other transmission mechanisms, such as two meshing bevel gears.

[0118] See also Figures 2 to 4For example, the shielding cover 100 may include a cover body 101 and a cover body 102. An opening 101a is provided in the cover body 101. The cover body 102 is movably connected to the cover body 101 between an open position for opening the opening 101a and a closed position for shielding the opening 101a. When the cover body 102 is in the open position, the opening 101a is opened, and at this time, the handle member 111 can pass through the opening 101a to reach the outside of the cover body 101, or be retracted from the outside of the cover body 101 through the opening 101a to the accommodating chamber 101b. When the cover body 102 is in the closed position, the cover body 102 can shield the opening 101a, thereby shielding, storing and protecting the shift assembly 110, and can also reduce the occupation of the external space by the handle member 111, making the external structure simpler, neater and more beautiful.

[0119] Further, the cover body 102 is translationally connected to the cover body 101 along the translation direction D1 perpendicular to the length direction D2. The shifting device may also include a screw member 125, a nut member 126 and a second motor 127. The screw member 125 is rotatably connected to the cover body 101 around its own axis. The axis of the screw member 125 is parallel to the translation direction D1. The nut member 126 is connected to the cover body 102 and screwed to the screw member 125. The output shaft of the second motor 127 is connected to the screw member 125 to drive the screw to rotate, so that the cover body 102 is translated along the translation direction D1. Here, by arranging the cover body 102 movably in the translation direction D1 perpendicular to the length direction D2, the space occupied by the movement of the cover body 102 in the length direction D2 can be reduced, so that the overall structure is more compact in the length direction D2. The screw-nut mechanism composed of the screw member 125 and the nut member 126 is used to realize power transmission, so that the displacement of the cover body 102 can be controlled more accurately.

[0120] See also Figure 4 In addition, the shift device may further include a first position sensor 128 and a second position sensor 129. The first position sensor 128 is located in the accommodating cavity 101b and is connected to the cover body 101. The first position sensor 128 is configured to sense the cover body 102 in the open position. The second position sensor 129 is located in the accommodating cavity 101b and is connected to the cover body 101. The second position sensor 129 is configured to sense the cover body 102 in the closed position. By providing the first position sensor 128 and the second position sensor 129 to detect the position of the cover body 102, it is possible to facilitate the linkage control of the start and stop sequence of the first motor 124 and the second motor 127 in the vehicle automatic control system, thereby helping to provide users with a more comfortable and convenient use experience.

[0121] For example, the first position sensor 128 and the second position sensor 129 can be position sensing devices such as travel switches and infrared sensors.

[0122] In some other examples not shown, a position sensor may also be provided at the limit position of the rotation stroke of the rotating drum 121 to detect the rotating drum 121 that has rotated to the correct position.

[0123] In a specific application, the shielding cover 100 may be a part of the shell of the center console of the vehicle.

[0124] See 2 and Figure 4 When the handle member 111 is in the storage position, the shift assembly 110 is hidden in the accommodating cavity 101b of the shielding cover 100. There is an opening 101a at the top of the shielding cover 100, which allows the handle member 111 to slide in and out. The shielding cover 100 is provided with a slide groove feature, and the cover body 102 can slide along the slide groove in a straight line. A nut member 126 is installed on the cover body 102. The nut is connected to the screw member 125 fixed on the second motor 127 of the shielding cover 100. The second motor 127 can push the cover body 102 to slide forward by driving the screw member 125 to rotate. A first position sensor 128 and a second position sensor 129 are fixed at the front and rear ends of the moving direction of the cover body 102. When the cover body 102 touches the first position sensor 128 and the second position sensor 129, the second motor 127 will stop rotating.

[0125] See also Figures 2 to 4 The method of using the shifting device of the utility model may include the following contents:

[0126] When the user unlocks the door or needs to use the shift handle in other ways, the second motor 127 drives the screw rod 125 to rotate, thereby pushing the cover 102 to slide toward the open position through the cooperation of the screw rod 125 and the nut 126 on the cover 102. When the cover 102 is in the open position, it stops rotating after touching the first position sensor 128, and the first motor 124 starts to rotate. When the first motor 124 starts to rotate, the first motor 124 drives the worm 122 to rotate, thereby driving the rotating cylinder 121 to rotate around the connecting cylinder 117 through the cooperation of the worm 122 and the worm wheel 123. During the rotation of the rotating cylinder 121, the rotating cylinder 121 pushes the guide protrusion 114a at the lower end of the first rod 114 to slide upward along the guide hole 117b on the connecting cylinder 117 through the spiral part 121b of the vacant part 121a, thereby driving the first rod 114 to move upward. When the guide protrusion 114a is pushed to the positioning portion 121c of the vacant portion 121a by the rotating cylinder 121, the first motor 124 stops rotating, thereby achieving the purpose of adjusting the handle member 111 connected to the first rod 114 to the extended position.

[0127] When the user locks the car door or needs to hide the shift handle in other situations, the first motor 124 is controlled to start rotating. The first motor 124 drives the rotating cylinder 121 to rotate around the connecting cylinder 117 through the worm 122 and the worm wheel 123, so that the guide protrusion 114a at the lower end of the first rod 114 is pushed to slide downward along the guide hole 117b of the connecting cylinder 117 through the vacant part 121a on the rotating cylinder 121, and then the first rod 114 moves downward. When the guide protrusion 114a is pushed to the bottom of the spiral part 121b of the vacant part 121a of the rotating cylinder 121, the first motor 124 stops rotating, and the second motor 127 starts rotating. At this time, the purpose of adjusting the handle member 111 connected to the first rod 114 to the storage position is achieved. During the rotation of the second motor 127 , the second motor 127 drives the screw rod 125 to rotate and pushes the cover 102 to slide. When the cover 102 moves to the closed position, it touches the second position sensor 129 and stops rotating, thereby realizing the hiding function.

[0128] The utility model drives the worm 122 and the worm wheel 123 to rotate by the first motor 124 to realize the lifting and lowering of the handle member 111, and drives the screw member 125 and the nut member 126 to rotate by the second motor 127 to realize the opening and closing of the cover body 102. When the cover body 102 is in the closed position, the handle member 111 is completely hidden in the inner cavity of the console, and the handle member 111 is completely invisible from the outside, making the entire console look simpler and neater. When the worm wheel 123 and the worm 122 are designed to meet the self-locking condition, it can be achieved that the handle member 111 will not cause the worm 122 to rotate during the manual shifting operation, thereby ensuring the reliability of the shifting handle.

[0131] According to the vehicle of the present invention, by applying the above-mentioned shifting device, while being able to adjust the position of the handle member 111 in the height direction of the vehicle, it can also meet the demand of storing the handle member 111 when not in use, thereby helping to increase the space inside the vehicle and improve the user experience.
