Description

Technical Field

[0001] The utility model relates to the technical field of shifting mechanisms, in particular to a shifting lever structure of a shifting operating mechanism panel. Background Art

[0002] The lever structure of the electronic shift control mechanism is mainly composed of a lever body, a shift cable, an angle sensor and a signal processing circuit. The lever body is provided with multiple shift positions. One end of the shift cable is connected to the lever body, and the other end is connected to the gearbox's shift mechanism. The angle sensor is installed on the lever structure to detect the rotation angle of the lever. The signal processing circuit is responsible for processing the signal output by the angle sensor and converting it into a digital signal that the gearbox can understand. When the driver pulls the lever, the lever body will rotate, driving the shift cable to move, transmitting power to the gearbox, and realizing the shift operation. At the same time, the rotation of the lever will also be detected by the angle sensor. The signal processing circuit receives the signal output by the angle sensor, processes it, and converts it into a digital signal. The digital signal is transmitted to the control unit of the gearbox. The control unit controls the gearbox to complete the gear shifting operation according to the received signal. However, after the operation is completed, the current electronic gear shifting mechanism needs to use structures such as zippers and springs to force the lever to reset itself to wait for the next shifting operation of the lever. For compact cars, reset structures such as springs and cables need to occupy the vertical and longitudinal installation space inside the shift panel, armrest box and center console, which will limit the layout of other components.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-5 The utility model provides an embodiment: a shift lever structure of a shift control mechanism panel, comprising an upper panel 1 and a circular bottom frame 2 bolted to the bottom end of the upper panel 1, and an outer circular frame 101 is integrally formed at the bottom end of the upper panel 1 on the outer circumference of the circular bottom frame 2, a main shaft 5 is rotatably mounted on the inner wall of one side of the circular bottom frame 2 through a bearing, an angle sensor 4 is mounted on the inner wall of the other side of the circular bottom frame 2, one end of the main shaft 5 is integrally formed with a straight-shaped convex key 501 for connecting to the input end of the angle sensor 4, an arc disk 6 is fixed on the surface of the main shaft 5, and a shift lever body 8 is fixed on the top end of the arc disk 6, and a self-torsion reset structure 7 is installed on the outer wall of one side of the outer circular frame 101, and the self-torsion reset structure 7 is used to prevent the main shaft 5 from rotating;

[0019] The spindle 5 is connected to the rotation angle sensor 4 through a flat convex key 501. The rotation angle sensor 4 calculates the rotation angle of the lever body 8, the spindle 5, and the arc-shaped plate 6 by measuring the change of resistance or capacitance, and transmits the detected rotation angle signal to the gearbox control unit, thereby realizing the gearbox shifting operation;

[0020] A completely penetrating positioning hole 102 is provided at the corner position of the top end of the upper panel 1, and a countersunk hole extending upward is provided at the corner position of the bottom end of the circular bottom frame 2, and a bolt for connecting the upper panel 1 is installed inside the countersunk hole;

[0021] A U-shaped support seat 3 is integrally formed at both side edges of the bottom end of the upper panel 1. Through holes are provided on both sides of the inside of the U-shaped support seat 3. The through holes penetrate to the outside of the upper panel 1 and the U-shaped support seat 3. The circular bottom frame 2 and the upper panel 1 are connected by four bolts, so that the upper panel 1 and the circular bottom frame 2 are stably connected;

[0022] An annular groove and a circular ring 701 fixed inside the annular groove are provided on the outer wall of one side of the outer circular frame 101. One end of the main shaft 5 passes through the outside of the circular ring 701 and is fixed with a baffle 703. A torsion spring 704 is installed on the outer peripheral surface of the main shaft 5 on one side of the baffle 703. The two ends of the torsion spring 704 overlap with the baffle 703 and the circular ring 701 respectively. Two clamping feet 702 are integrally formed on both sides of the bottom end of the circular ring 701. A gap is provided between the two clamping feet 702. A rectangular groove is provided on the outer peripheral surface of the baffle 703. A first crooked foot 7041 and a second crooked foot 7042 are provided at both ends of the torsion spring 704 respectively. The first crooked foot 7041 overlaps with the rectangular groove, and the second crooked foot 7042 overlaps with the gap.

[0023] When the lever body 8 drives the arc disk 6 and the main shaft 5 to rotate, the end of the main shaft 5 away from the flat key 501 drives the baffle plate 703 to rotate. Since the first leg 7041 and the second leg 7042 of the torsion spring 704 are respectively stuck on the baffle plate 703 and the clamping foot 702, the torsion spring 704 is twisted and generates elastic force under the drive of the baffle plate 703. When the user's shifting action is completed, the torsion spring 704 begins to reset, and then the lever body 8 and the arc disk 6 are swung to the center position. This structural design will make the installation and maintenance of the shift operating mechanism easier, and when the shift operating mechanism fails, it can be quickly inspected and maintained.

[0024] When the embodiment of the present application is in use, first, the upper panel 1 in the structure is installed to the center console of the armrest box, and the driver shifts the lever body 8, and the arc disk 6 and the main shaft 5 are driven to rotate by the lever body 8. One end of the main shaft 5 is interconnected with the input end of the angle sensor 4 through a straight-shaped convex key 501. The angle sensor 4 detects the rotation angle of the lever body 8 and the main shaft 5, and transmits the signal to the transmission control unit to realize the gear shifting operation. After the rotation of the lever body 8 is completed and the driver no longer applies force, the self-torsion reset structure 7 begins to play a role, that is, the self-torsion reset structure 7 forces the main shaft 5, the arc disk 6, the lever body 8 and other components to automatically reset to wait for the next lever operation. The setting of the cable is omitted in the lever structure, which can effectively reduce the installation space of the gear shifting mechanism. For compact cars, it can alleviate the space limitation problem and allow the center console of the armrest box to have more freedom to optimize the design.

[0025] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
