Description

Technical Field

[0001] The present application relates to the field of automobile technology, and in particular to an automatic shifting device guide mechanism and a vehicle suitable for automatic transmission vehicles. Background Art

[0002] Modern cars are divided into automatic transmission and manual transmission based on the gear shifting method. The "D" gear of automatic transmission vehicles is automatically shifted by the on-board computer ECU monitoring various vehicle driving data in real time, but the switching between "P", "R", "N" and "D" gears still requires manual pulling of the automatic gear lever. In order to realize the automatic switching between the "P", "R", "N" and "D" gears of automatic transmission vehicles, an additional device needs to be added. However, the existing device has a complex structure and occupies a large space, which is not conducive to practical implementation.

[0003] The patent application with publication number CN 216200417 U discloses an automatic shifting device and vehicle suitable for automatic transmission vehicles, including a power element, an actuator and a guide structure for guiding the actuator. The actuator end is used to drive the automatic gear lever. The actuator moves along a set route under the drive of the transmission element so that the actuator end has a motion component parallel to the shifting direction of the automatic gear lever. The guide structure in the patent application includes a first guide part and a second guide part arranged on the bracket and a third guide part arranged on the base. The actuator is slidably arranged in the first guide part and the third guide part. The first guide part and the third guide part are linear bearings. The actuator is inserted into two linear bearings arranged opposite to each other. The second guide part has a guide groove. The bending part passes through the guide groove and can slide along the guide groove to generate a component parallel to the shifting direction.

[0004] However, the patent application uses linear bearings as guides, which has many disadvantages:

[0005] 1. The actuator is a movable rod with its ends inserted into two linear bearings. When the actuator is driven to move, it cannot be guaranteed that the front and rear ends of the actuator are located on the same plane. Due to the different front and rear slopes of the vehicle body or the different inclination angles of the front and rear ends of the actuator, the actuator may not move smoothly, or even get stuck and cannot be moved, making automatic shifting impossible.

[0006] 2. The balls in the linear bearing will press many grooves on the outer surface of the actuator's rod end, causing the actuator to wear faster and shorten its service life;

[0007] 3. Linear bearings have high requirements for machining dimensional accuracy. There are easy assembly problems between linear bearings and actuators. If the machining dimensional accuracy is not high, the actuator will not be able to penetrate into the linear bearing, or there will be a gap between the actuator and the linear bearing, which is easy to loosen.

[0008] Therefore, the present application provides an automatic shift device guide mechanism suitable for automatic transmission vehicles to solve the above problems. Utility Model Content

[0009] To solve the above problems, the present application provides a guide mechanism for an automatic shift device suitable for automatic transmission vehicles. The transmission rod is aligned with the front and rear slopes of the vehicle body, the movement direction of the transmission rod is limited by a guide member, and the driving force is relatively smooth during automatic shifting. The technical solution is as follows:

[0010] The first aspect of the present application provides an automatic shifting device guide mechanism suitable for automatic transmission vehicles, including an automatic gear handle mounting base, a drive mechanism base, a transmission rod and a guide member. The automatic gear handle mounting base is used to install the automatic gear handle, and the drive mechanism base is used to install the drive mechanism. One end of the transmission rod is connected to the automatic gear handle, and the other end is connected to the drive mechanism. The transmission rod is driven to move by the drive mechanism, and the automatic gear handle is driven to move to achieve gear shifting; the guide member is connected to one side of the transmission rod and is arranged parallel to the transmission rod, and the transmission rod moves linearly along the guide member.

[0011] For example, in the guide mechanism of the automatic shifting device suitable for automatic transmission vehicles provided in one embodiment, the guide member includes a guide rail and a slider, one end of the guide rail is fixedly connected to the automatic gear handle mounting seat, and the other end is fixedly connected to the drive mechanism base; the slider is provided on the guide rail and can slide along the guide rail, and the slider is fixedly connected to the transmission rod so that when the drive mechanism drives the transmission rod to move, the transmission rod can be moved linearly along the guide rail through the slider.

[0012] For example, in the automatic shifting device guide mechanism suitable for automatic transmission vehicles provided in one embodiment, the guide member also includes a connecting block for connecting the transmission rod and the slider, and the connecting block is provided on the surface of the slider away from the guide rail.

[0013] For example, in the automatic shifting device guide mechanism suitable for automatic transmission vehicles provided in one embodiment, a through hole for screws to pass through is provided on the side surface of the transmission rod, and the transmission rod is fixedly connected to the connecting block by screws.

[0014] For example, in the automatic shifting device guide mechanism suitable for automatic transmission vehicles provided in one embodiment, an arc-shaped gasket is provided between the connecting block and the transmission rod, and the arc-shaped gasket is used to half-wrap the outer wall of the transmission rod.

[0015] For example, in the automatic shifting device guide mechanism suitable for automatic transmission vehicles provided in one embodiment, two sliders fixedly connected to the transmission rod are provided on the guide rail, one of the sliders is close to the automatic gear handle mounting seat, and the other slider is close to the drive mechanism base.

[0016] For example, in the automatic shifting device guide mechanism suitable for automatic transmission vehicles provided in one embodiment, mounting plates are provided on the automatic gear lever mounting seat and the drive mechanism base, and both ends of the guide rail are fixedly connected to the mounting plates respectively.

[0017] For example, in the automatic shifting device guide mechanism suitable for automatic transmission vehicles provided in one embodiment, an elliptical hole for screws to pass through is provided on the mounting plate, the guide rail is fixedly connected to the mounting plate by screws, and fine-tuning is achieved through the elliptical hole.

[0018] For example, in the guide mechanism of the automatic shift device applicable to an automatic transmission vehicle provided in one embodiment, the guide member is located below the transmission rod.

[0019] A second aspect of the present application provides a vehicle comprising any of the above-described automatic shifting device guide mechanisms applicable to automatic transmission vehicles.

[0020] The beneficial effects brought by an automatic shifting device guide mechanism and vehicle suitable for automatic transmission vehicles provided in some embodiments of the present application are as follows: in the present application, the transmission rod is mounted on the guide rail to form a whole, and the two are arranged in parallel along the axial direction. The slope and inclination angle of the guide member are consistent with the front and rear slopes of the vehicle body, so that the transmission rod is consistent with the front and rear slopes of the vehicle body. The moving direction of the transmission rod is limited by the guide member, so that the transmission rod can only move in a straight line along the guide member, and is pushed relatively smoothly during automatic shifting, thereby avoiding the problems in the automatic shifting device of the existing automatic transmission vehicle model where the front and rear ends of the transmission rod are not in the same plane, the transmission rod and the front and rear slopes of the vehicle body are inconsistent, resulting in the transmission rod being stuck and unable to move.

[0026] The first aspect of the present application provides an automatic shifting device guide mechanism suitable for automatic transmission vehicles, such as Figure 1 As shown, it includes an automatic gear handle mounting base 1, a drive mechanism base 2, a transmission rod 3 and a guide member 4. The automatic gear handle mounting base 1 is used to install the automatic gear handle 11, and the drive mechanism base 2 is used to install the drive mechanism 21. One end of the transmission rod 3 is connected to the automatic gear handle 11, and the other end is connected to the drive mechanism 21. The transmission rod 3 is driven to move by the drive mechanism 21, and the automatic gear handle 11 is driven to move to achieve gear shifting; the guide member 4 is connected to one side of the transmission rod 3 and is arranged parallel to the transmission rod 3. The transmission rod 3 moves in a straight line along the guide member 4.

[0027] The present application is applicable to the guide mechanism of the automatic shifting device of automatic transmission vehicle models, in which the transmission rod 3 is connected to the guide member 4 to form an integrated structure, which is installed between the automatic transmission handle mounting base 1 and the drive mechanism base 2. The slope and inclination angle of the guide member 4 are consistent with the front and rear slopes of the vehicle body, so that the transmission rod 3 is consistent with the front and rear slopes of the vehicle body. The moving direction of the transmission rod 3 is limited by the guide member 4, so that the transmission rod 3 can only move in a straight line along the guide member 4, and is pushed relatively smoothly during automatic shifting, thereby avoiding the problems in the automatic shifting device of the existing automatic transmission vehicle models where the front and rear ends of the transmission rod 3 are not in the same plane, the transmission rod 3 and the front and rear slopes of the vehicle body are inconsistent, resulting in the transmission rod 3 being stuck and unable to move.

[0028] For example, in the automatic shifting device guide mechanism applicable to automatic transmission vehicles provided in one embodiment, Figure 2 As shown, the guide member 4 includes a guide rail 41 and a slider 42, one end of the guide rail 41 is fixedly connected to the automatic gear handle mounting seat 1, and the other end is fixedly connected to the drive mechanism base 2; the slider 42 is provided on the guide rail 41 and can slide along the guide rail 41, and the slider is fixedly connected to the transmission rod 3 42, so that when the drive mechanism 21 drives the transmission rod 3 to move, the transmission rod 3 can be moved linearly along the guide rail 41 through the slider 42.

[0029] Among them, the guide member 4 is located below the transmission rod 3, and the transmission rod 3 is mounted on the guide rail 41. The two are arranged in parallel along the axial direction. The transmission rod 3 and the guide rail 41 form a whole and move along the guide rail 41 through the slider 42. During installation, the transmission rod 3 and the guide rail 41 are first assembled into a whole to ensure that the two ends of the transmission rod 3 are in the same plane and consistent with the front and rear slopes of the vehicle body. The length of the guide rail 41 is slightly larger than the length of the transmission rod 3, thereby ensuring that the transmission rod 3 has sufficient space to move.

[0030] The present application uses the guide rail 41 and the slider 42 to limit the moving direction of the transmission rod 3, overcoming the defect that the linear bearing causes the transmission rod 3 to be stuck when shifting due to the slope and inclination angle at both ends of the transmission rod 3 being inconsistent with the vehicle body. The guide rail 41 is easy to install and will not cause wear to the transmission rod 3. The guide rail 41 also has low requirements for processing dimensional accuracy and low cost.

[0031] A slider 42 may be provided on the guide rail 41. The slider 42 is located in the middle of the guide rail 41 and is fixedly connected to the middle of the transmission rod 3. By connecting a slider 42 to the middle of the transmission rod 3, the transmission rod 3 can be driven to move linearly along the guide rail 41.

[0032] or as Figure 1As shown, two sliders 42 fixedly connected to the transmission rod 3 are provided on the guide rail 41, one of the sliders 42 is close to the automatic gear handle mounting seat 1, and the other slider 42 is close to the drive mechanism base 2; by respectively providing a slider 42 at both ends close to the transmission rod 3, the moving direction of the transmission rod 3 can be strengthened, ensuring that both ends of the transmission rod 3 move along the guide rail 41, thereby improving the smoothness of the movement of the transmission rod 3.

[0033] Or three sliders 42 fixedly connected to the transmission rod 3 are provided on the guide rail 41, wherein two sliders 42 are respectively located at the two end areas of the guide rail 41, and the other slider 42 is located in the middle area of ​​the guide rail 41. Both ends and the middle of the transmission rod 3 are fixedly connected to the guide rail 41 through the sliders 42 to further strengthen the definition of the moving direction of the transmission rod 3.

[0034] For example, in the automatic shifting device guide mechanism applicable to automatic transmission vehicles provided in one embodiment, Figure 2 As shown, the guide member 4 further includes a connecting block 43 for connecting the transmission rod 3 and the slider 42 . The connecting block 43 is provided on a surface of the slider 42 facing away from the guide rail 41 .

[0035] The four corners of the connecting block 43 are provided with through holes, screws are provided in the through holes, and the connecting block 43 is fixedly connected to the slider 42 through the screws.

[0036] For example, in the automatic shifting device guide mechanism applicable to automatic transmission vehicles provided in one embodiment, Figure 2 As shown, a through hole 31 for screws to pass through is provided on the side surface of the transmission rod 3, and the transmission rod 3 is fixedly connected to the connecting block 43 by screws.

[0037] According to the above embodiment, by drilling the through hole 31 on the transmission rod 3, the transmission rod 3 and the connecting block 43 are fixedly connected by screws, which is convenient to install, firmly connected, and easy to operate.

[0038] For example, in the automatic shifting device guide mechanism applicable to automatic transmission vehicles provided in one embodiment, Figure 2 As shown, an arc-shaped gasket 44 is provided between the connecting block 43 and the transmission rod 3 , and the outer wall of the transmission rod 3 is half-wrapped by the arc-shaped gasket 44 .

[0039] The arc-shaped gasket 44 is an iron sheet, which half-wraps the outer wall of the transmission rod 3 to further strengthen the connection strength between the transmission rod 3 and the connecting block 43 and avoid looseness between the transmission rod 3 and the slider 42.

[0040] For example, in the automatic shifting device guide mechanism applicable to automatic transmission vehicles provided in one embodiment, Figure 1 As shown, a mounting plate 5 is provided on the automatic gear lever mounting base 1 and the driving mechanism base 2 , and both ends of the guide rail 41 are fixedly connected to the mounting plate 5 .

[0041] For example, in the automatic shifting device guide mechanism applicable to automatic transmission vehicles provided in one embodiment, Figure 1 As shown, an elliptical hole 51 for screws to pass through is provided on the mounting plate 5 , the guide rail 41 is fixedly connected to the mounting plate 5 by screws, and fine adjustment is achieved through the elliptical hole 51 .

[0042] According to the above embodiment, by setting an elliptical hole 51 on the mounting plate 5, the guide rail 41 can be provided with the ability to provide angle adjustment for installation. The angle adjustment function of the elliptical hole can be used to solve the deviation of the guide rail 41 during the installation process. Fine-tuning can be performed to achieve precise installation of the guide rail 41 to adapt to the installation environment of different vehicle bodies, with flexibility and accuracy.

[0043] A second aspect of the present application provides a vehicle comprising any of the above-described automatic shifting device guide mechanisms applicable to automatic transmission vehicles.

[0044] Although the implementation scheme of the present application has been disclosed as above, it is not limited to the applications listed in the description and implementation mode. It can be fully applied to various fields suitable for the present application. For those familiar with this field, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present application is not limited to the specific details and illustrations shown and described herein.
