Description

Technical Field

[0001] The invention relates to an automatic gear shifting manipulator for a vehicle, belonging to the technical field of driving devices. Background Art

[0002] In recent years, as people pursue a higher quality of life, the demand for automatic transmission vehicles and self-driving vehicles has increased, and more and more people have conducted extensive research in this field. Among them, the automatic shift robot is not only a research object for the shift device of automatic transmission vehicles, but also a research object for the shift device of self-driving vehicles. The automatic shift robot can control the relationship between the clutch and the vehicle sensor through a computer, so that it can accurately complete the vehicle's shifting action, and can also complete the switching between starting and reversing. Therefore, the automatic shift robot can be used on any vehicle that needs to shift gears.

[0003] Chinese patent CN201110359937.4 discloses a shifting manipulator realized by a pneumatic structure, which uses a cylinder as the shifting power, or adds an air source to the vehicle, which is not conducive to promotion. Chinese patent CN2015101881.6 discloses a vehicle synchronizer test bench shifting manipulator and its control, which uses a cylinder and a motor, and also needs to add an air source to the vehicle, which is not conducive to promotion. Chinese patent CN109228856A discloses an automatic driving robot shifting manipulator, which uses a dual stepping motor plus a slider connecting rod mechanism, and has a complex structure. The gear shifting handle requires two motors to cooperate to move in two dimensions, which is not conducive to precise control. Chinese patent CN110091313A discloses a shifting manipulator based on a parallel actuator, which uses a linear motor plus two quadrilateral connecting rods and many other connecting rods. The structure is also very complex. At the same time, the shifting and selecting gears also require the cooperation of two motors, and the movement mode is complex. Summary of the invention

[0004] The purpose of the present invention is to provide a vehicle automatic gear shifting manipulator to achieve a precise, convenient and fast gear shifting function for the vehicle.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: A vehicle automatic shifting manipulator, comprising a first linear motor, a first slider seat, a second linear motor, a second slider seat, a slider support, a guide rod, a connecting rod, a force sensor, a joint bearing, and a gripper. The first linear motor is fixedly mounted on the vehicle, the first slider seat is slidably connected to the first linear motor, the second linear motor is fixedly mounted on the first slider seat, the second slider seat is slidably connected to the second linear motor, the slider support is fixedly mounted on the first slider seat, the guide rod is slidably connected to the slider support, one end of the connecting rod is hingedly mounted on the guide rod, and the other end is hingedly mounted on the second slider seat, the force sensor is fixedly mounted on the guide rod, the joint bearing is fixedly mounted on the force sensor, the gripper is fixedly mounted on the joint bearing, and the gripper is fixedly slidably connected to the shift handle.

[0006] The beneficial effects of the present invention are as follows: (1) The gear selection and shifting of the automatic gear shifting robot of the present invention are two independent movements, which makes the gear shifting process more precise and more convenient, realizes the decoupling of the gear shifting process, and is easy to control; at the same time, it can also be linked through a control program or software to realize routes of various shapes, greatly improving the application scope of the automatic gear shifting robot of the present invention. (2) The automatic gear shifting robot of the present invention has a simple and stable structure, a simple and fast movement principle, and is easy to operate; (3) A force sensor is provided at the gripper of the automatic gear shifting robot of the present invention for feedback, thereby avoiding unsafe hidden dangers caused during the gear shifting process.

[0011] The present invention will be further described below in conjunction with specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention.

[0012] See also Figure 1 to Figure 3The present invention provides the following technical solution: A vehicle automatic gear shifting manipulator includes a first linear motor 1, a first slider seat 2, a second linear motor 3, a second slider seat 4, a slider support 5, a guide rod 6, a connecting rod 7, a force sensor 8, a joint bearing 9, and a gripper 10. The first linear motor 1 is fixedly mounted on the vehicle, the first slider seat 2 is slidably connected to the first linear motor 1, the second linear motor 3 is fixedly mounted on the first slider seat 2, the second slider seat 4 is slidably connected to the second linear motor 3, the slider support 5 is fixedly mounted on the first slider seat 2, the guide rod 6 is slidably connected to the slider support 5, one end of the connecting rod 7 is hingedly mounted on the guide rod 6, and the other end is hingedly mounted on the second slider seat 4, the force sensor 8 is fixedly mounted on the guide rod 6, the joint bearing 9 is fixedly mounted on the force sensor 8, the gripper 10 is fixedly mounted on the joint bearing 9, and the gripper 10 is slidably connected to the gear shifting handle.

[0013] The working principle of the present invention is as follows: first, after the first linear motor 1 drives the first slider seat 2 to move to the shift position, the second linear motor 3 drives the second slider seat 4 to move, thereby driving the connecting rod 7 to swing, and then driving the guide rod 6 to slide along the guide groove of the slider support 5.

[0014] Secondly, when shifting along other shapes of routes, the first linear motor 1 and the second linear motor 3 are controlled by a computer or other controller to simultaneously drive the first slider seat 2 and the second slider seat 4 to perform linkage, thereby controlling the shift handle to move along any shape of routes.
