[0002] Vehicles equipped with an electronic shift system may or may not have a manual mode depending on the type of vehicle transmission device.

[0003] When the transmission device has a manual mode, the electronic shift control mechanism assembly needs to correspondingly have a manual mode, otherwise the manual shifting function cannot be used.

[0004] For vehicles without a manual mode in the transmission device, the electronic shift control mechanism assembly cannot have a manual mode.

[0005] The conventional way to add a manual mode is to add a manual mode button to the shift handle or panel, or add an M gear to the shifter, which will result in a complex structure and increased cost; at the same time, it affects the platformization and generalization of the electronic shift control mechanism assembly, leading to an increase in product cost.

[0006] At the same time, in the traditional shift control mechanism, when quickly pushed to the front or rear extreme positions, the shift lever will collide with the housing and make abnormal noises, affecting the product quality.

[0007] At the same time, for some traditional electronic shifter control mechanisms, when the shift lever moves, there is a lack of a travel limit structure, which is prone to mis-shifting operations.

[0008] After retrieval, the existing patent 202322917916.0 - A shift lever for a tractor does not clearly solve the technical problems described above.

[0034] The following is a further detailed description of the specific embodiments of the present utility model by describing the optimal embodiments with reference to the accompanying drawings.

[0035] A shift lever limit structure includes a limit block 1, and the limit block 1 includes an intermediate block 11. One end of the intermediate block 11 is provided with a first block 12, and the other end is provided with a second block 13; the first block 12 and the second block 13 are spaced apart; the vertical cross-sectional area of the intermediate block 11 is smaller than the vertical cross-sectional areas of the first block 12 and the second block 13; the limit block 1 disclosed in the present utility model can be used to limit the moving stroke of the shift lever 3 in the shift control assembly, and the swing range of the shift lever 3 can be changed according to the design requirements of the shift control assembly during subsequent use.

[0036] Based on the limiting effect of the limit block 1, the essential purpose is to control the swing range below the shift lever 3, so as to control the shift gears.

[0037] In the present utility model, the limit block 1 includes an intermediate block 11, and the intermediate block 11 mainly acts as a connecting block. One function is to realize the connection between the first block 12 and the second block 13; and it is also convenient for the installation and fixation of the limit block 1 on the shift housing 2.

[0038] In the present utility model, one end of the intermediate block 11 is provided with a first block 12, and the other end is provided with a second block 13; the first block 12 is used for the limit fixation of the non-manual mode shifting mechanism, and the second block 13 is used for the limit fixation of the manual mode shifting mechanism. That is, the present utility model realizes the position limitation of the shifting control mechanism in different modes by controlling the installation orientation of the first block 12 and the second block 13 in the limit block 1.

[0039] Meanwhile, in the present utility model, the first block 12 and the second block 13 are spaced apart; the vertical cross-sectional area of the intermediate block 11 is smaller than the vertical cross-sectional areas of the first block 12 and the second block 13; based on such a setting, the limit block 1 disclosed in the present utility model has a structure that is thin in the middle and thick at both ends, so that a groove structure is formed on the limit block 1, which is convenient for the subsequent snap-in installation of the limit block 1 inside the shifting housing 2 and can prevent the limit block 1 from moving around at the connection.

[0040] Furthermore, in the present utility model, the thickness of the first block 12 is greater than the thickness of the second block 13; based on such a setting, the first block 12 occupies a larger lateral position than the second block 13, so that when in use, the first block 12 contacts the shift lever 3 first. Therefore, the first block 12 can be used for the non-manual mode electronic shifting control assembly to avoid accidentally shifting into the manual gear slot; similarly, since the second block 13 has a smaller lateral dimension, it can limit the position while not blocking the shift lever 3 from entering the manual shift slot 401. Therefore, the limit block 1 disclosed in the present utility model can be applied to automobiles without a manual mode in the transmission device; it can also be applied to automobiles with a manual mode in the transmission device, with excellent specific use effects.

[0041] In addition, it should be stated here that the limit block 1 disclosed in the present utility model is provided on a transmission device, and the transmission device has a brand-new electronic shifter control assembly, which can take into account models that do not require a manual mode while providing a manual mode.

[0042] By setting the limit block 1 in the present utility model, the movement stroke of the shift lever 3 can be controlled based on the installation direction of the limit block 1, so as to prevent the shift lever 3 from shifting into the manual shift slot 401 that does not require a manual mode.

[0043] Furthermore, in the present utility model, an anti-misoperation groove 14 is provided at one end of the first block 12 and / or the second block 13 close to the intermediate block 11; the anti-misoperation groove 14 disclosed in the present utility model is mainly used in cooperation with the anti-misoperation boss 22 at the edge of the snap-in groove 21 to prevent the wrong installation direction of the limit block 1; meanwhile, in actual use, the dimensions, structures, and installation positions of the anti-misoperation boss 22 and the anti-misoperation groove 14 can be controlled to prevent the wrong installation direction of the limit block 1 and avoid the wrong installation of the limit block 1 model.

[0044] Further, in the present utility model, the limit block 1 is made of rubber material; the limit block 1 made of rubber material has a certain isolation and shock absorption effect, optimizing the vehicle NVH during gear shifting.

[0045] In addition, in the present utility model, a guiding inclined surface is provided on the second block 13; in the present utility model, after the shift lever 3 is engaged in the shift groove 401 of the manual mode, the inclination angle of the shift lever 3 is relatively large. The present utility model adopts the design of an inclined surface to avoid the influence of the sharp corners of the second block 13 on the normal gear shifting operation of the shift lever 3.

[0046] A shift control assembly includes a shift housing 2, a shift block 4 is provided on the shift housing 2, and a shift groove 401 is provided on the shift block 4; a shift lever 3 is provided on the shift housing 2; a shift lever limiting structure is provided inside the shift housing 2; the shift lever limiting structure is arranged towards the shift lever 3; in the present utility model, if the first block 12 in the limit block 1 is arranged towards the shift lever 3, it means that the shift control assembly cannot be directly changed to the manual mode; if the second block 13 in the limit block 1 is arranged towards the shift lever 3, it means that the shift control assembly has a manual mode.

[0047] Meanwhile, in the present utility model, the shift housing 2 is the main structure of the shift control assembly, and the shift lever 3 mainly cooperates with the shift groove 401 to achieve corresponding shift operations; the shift lever 3 and the shift block 4 can adopt conventional structures; or can be optimized according to needs.

[0048] Further, in the present utility model, a clamping groove 21 is provided on the inner wall of the shift housing 2; in the present utility model, the setting of the clamping groove 21 plays a good role in installation and limitation, facilitating the installation of the limit block 1 on the shift housing 2.

[0049] Meanwhile, in the present utility model, an anti-misalignment boss 22 is provided at the edge of the clamping groove 21 and is matched with the anti-misalignment groove 14 on the limit block 1; the anti-misalignment boss 22 of the present utility model is used in cooperation with the anti-misalignment groove 14 on the limit block 1, and the essential purpose is to avoid the wrong installation direction of the limit block 1.

[0050] Furthermore, in the present utility model, the shift slot 401 includes a first slot 41, a second slot 42, a third slot 43, a fourth slot 44, and a fifth slot 45 provided on the shift block 4; the first slot 41, the second slot 42, the third slot 43, the fourth slot 44, and the fifth slot 45 are sequentially distributed on the shift block 4; the first slot 41 and the second slot 42 are oppositely arranged with the third slot 43 and the fourth slot 44; in the present utility model, the first slot 41 and the second slot 42, as well as the third slot 43 and the fourth slot 44, are in a stepped structure. Such a setting enables the first slot 41, the second slot 42, the third slot 43, and the fourth slot 44 to form multiple gear positions, facilitating the cooperation with the shift lever 3 for use.

[0051] Meanwhile, in the present utility model, the fifth slot 45 is a manual shift slot 401; by shifting the shift lever 3 into the fifth slot 45, the manual mode can be switched.

[0052] In addition, in the present utility model, a fifth slot 45 is provided on the side of the fourth slot 44 away from the third slot 43; the inclination angle between the fifth slot 45 and the horizontal plane is greater than the inclination angle between the fourth slot 44 and the horizontal plane; based on the design with a larger inclination of the fifth slot 45 in the present utility model, the shift resistance during shifting can be increased, thereby reducing the probability of accidentally shifting into the manual shift slot 401.

[0053] Specifically:

[0054] The present utility model discloses a shift control assembly. Through the setting of the second slot 42, the number of the shift slot 401 bodies is increased; such that the shift control assembly disclosed in the present utility model can take into account models that do not require the manual mode while providing the manual mode.

[0055] The components of the electronic shift control mechanism assembly are completely universal, enabling the optimization of costs.

[0056] The shift control assembly of the present utility model is mainly an electronic shift control assembly; the shift control assembly of the present utility model is a single-stable shift lever 3 with two operating positions forward and three operating positions backward.

[0057] The two operating positions of the shift lever 3 forward and the two operating positions backward are for PRND gear position switching, and the third operating position backward is for manual mode shift.

[0058] When the shift lever 3 is pulled to the B3 position, the manual mode is entered, and then the shift lever 3 is operated for manual shifting; similarly, when the manual mode is shifted into B3 again, the manual mode is exited and the automatic transmission mode is entered.

[0059] The key point of the present utility model is to ensure that when the driver performs PRND gear shifting, the third operating position is not accidentally engaged; that is, it will not be engaged into the above-mentioned fifth groove body 45. Therefore, in the design, the following three points are ensured: 1. It is required that the fifth groove body 45 is in the last position of all groove bodies and does not interfere with the operation of PRND during normal use.

[0060] At the same time, this gear position is close to the D gear position to ensure that when this gear is engaged, the whole vehicle is in the D gear position; and this gear can only be engaged when the vehicle is in the D gear position; by changing the inclination of the fifth groove body 45, when it is used subsequently, the operating force for engaging this gear position is significantly greater than that of other gear positions. For example, the operating force can be twice that of shifting P, R, N, and D gears; at the same time, the travel for engaging this gear position is half of the travel for switching P, R, N, and D gears.

[0061] Based on the above, it can be known that the shift control assembly disclosed in the present utility model has the following beneficial effects:

[0062] The shift control assembly disclosed in the present utility model takes both the manual mode and the non - manual mode into consideration, and the parts are completely the same; the shift control assembly can be applied to all types of vehicles, which is more conducive to large - scale cost reduction.

[0063] Obviously, the specific implementation of the present utility model is not limited by the above - mentioned method. As long as various non - substantial improvements are made by adopting the method concept and technical solution of the present utility model, they are all within the protection scope of the present utility model.
