[0002] Chinese Patent No. ZL202221990944.4 discloses a shift knob for an automobile, comprising a shift bracket, a shift knob, and other components. The shift knob is used to shift gears while the vehicle is in motion, transferring the propulsion force from the engine to the driving system via the transmission. Traditional shift knobs typically shift gears manually, with the driver manually pushing the knob. This occupies a considerable amount of driving space, requiring further improvement. Summary of the Invention

[0003] The purpose of the present invention is to provide a sliding shift mechanism, in which a slider slides back and forth on a sliding seat through a sliding portion to form a sliding shift mechanism, eliminating the structure of a transmission pushing a shifter to shift gears, thereby reducing the overall volume of the sliding shift mechanism and saving driving space.

[0004] The object of the present invention is achieved like this:

[0005] A sliding shift mechanism includes a slider and a sliding seat. A sliding portion is provided between the slider and the sliding seat. The slider slides back and forth on the sliding seat through the sliding portion to form a sliding shift mechanism. The structure of the transmission pushing the shifter to shift gears is eliminated, thereby reducing the overall volume of the sliding shift mechanism and saving driving space.

[0006] The sliding part is a linear sliding part, and the slider slides linearly back and forth on the sliding seat through the linear sliding part; and the slider forms a sliding fit of surface contact, point contact, or line contact between the sliding part and the sliding seat. Specifically, the surface contact sliding fit is adopted, which has high stability, and during installation, a sliding part is provided between the slider and the sliding seat and is coated with grease to reduce friction and ensure that the slider slides smoothly when subjected to force.

[0007] The sliding part includes limiting guide ribs arranged on both sides of the sliding cavity of the sliding seat and a clamping groove arranged on the slider, which is clamped on the limiting guide ribs; the matching parts between the clamping grooves and the limiting guide ribs are in surface contact.

[0008] The sliding shift mechanism also includes a control device. A position detector for detecting the sliding position of the slider is provided on the control device corresponding to the reciprocating sliding direction of the slider. The position detector is at least one of a photoelectric sensor and a Hall sensor. The position detector is preferably a photoelectric sensor. When the sliding accessory of the slider slides on the protective cover of the control device, it will be captured by the photoelectric sensor. The photoelectric sensor converts the signal and outputs it to the MCU processor of the driving system. The MCU processor receives the signal, processes it, and outputs a corresponding electrical signal.

[0009] The sliding shift mechanism also includes a shift operating member that drives the slider to slide on the sliding seat. The shift operating member is located on the outside of the sliding seat. A light assembly is provided on the shift operating member. The light assembly includes a light-emitting member electrically connected to the control device through a flexible circuit. The light-emitting member forms a light indication when the slider slides.

[0010] The gear shift operating member includes a face shell provided with a first installation space, and a bottom shell and a light-shielding member located on the first installation space, and a second installation space for accommodating and installing the light-emitting member is formed between the bottom shell and the light-shielding member; the face shell and the light-shielding member are provided with light-transmitting portions at the radiation points corresponding to the light-emitting member, and the light emitted by the light-emitting member is irradiated onto the face shell through the light-transmitting portions of the face shell and the light-shielding member to form a light indication of sliding gear shifting on the face shell. When the slider slides to shift gears, there is a light display, and the light-emitting member slides with the slider. When it moves to the corresponding gear position, the MCU processor receives the signal and controls the corresponding gear display light for display.

[0011] The sliding shift mechanism also includes a supporting base, a reset rod that moves elastically up and down is provided on the supporting base, a sliding accessory that cooperates with the reset rod is provided on the slider, and a sliding contact portion and a reset contact portion are provided between the sliding accessory and the reset rod. When the slider slides, one end of the reset rod contacts the sliding contact portion of the sliding accessory. When the slider is reset, the reset rod contacts the reset contact portion of the sliding accessory. The slider slides on the sliding seat through the cooperation of the sliding accessory and the reset rod. The reset rod contacts the sliding accessory to form a damped sliding of the slider on the sliding seat. When the slider slides back and forth, the reset rod moves up and down to generate damping, and after the slider performs sliding shifting, the reset rod resets the slider to wait for the next sliding shifting action.

[0012] The support base is provided with a third mounting space for accommodating and mounting the control device. The control device comprises a protective sleeve that fits over the PCB. A clearance is provided on the protective sleeve and the PCB, corresponding to one end of the reset lever. One end of the reset lever extends through the clearance and engages with the sliding fitting. The protective sleeve protects the PCB and can be a transparent silicone sleeve. The support base can be provided with heat dissipation holes to dissipate heat from the PCB.

[0013] The protective cover is provided with a guide groove on the sliding track of the sliding accessory, and the sliding accessory is provided with a limit sliding block that slides in the guide groove to prevent the sliding accessory from shifting when sliding with the slider, thereby avoiding the photoelectric sensor from failing to capture the sliding position of the sliding accessory.

[0014] A dust cover is provided on the sliding seat, and a first installation space is provided between the face shell and the slider; a bottom shell, a light shielding member, and a light emitting member are provided in the first installation space, with the light emitting member being disposed between the light shielding member and the light emitting member; the bottom shell is fixedly connected to the slider; a concave surface for applying an adhesive is provided between the face shell and the light shielding member, and the face shell and the light shielding member are fixedly connected by bonding with the adhesive;

[0015] The dust cover is provided with a first bent portion and a second bent portion which are spaced apart from each other, and a slot is formed between the first bent portion, the second bent portion and the dust cover; a positioning block is provided on the sliding seat corresponding to the slot, the slot of the dust cover is positioned on the positioning block of the sliding seat, and the dust cover covers the slider in the sliding seat;

[0016] The dust cover is provided with an air avoidance opening for avoiding the connection between the bottom shell and the slider. The air avoidance opening is connected to the first installation space. The surface shell is located outside the dust cover and covers the air avoidance opening. When the shift operating part drives the slider to slide, the surface shell always covers the air avoidance opening to prevent external dust from falling into the sliding seat; the bottom shell plays the role of supporting the light-emitting part, and the outer periphery of the light-shielding part covers the light-emitting part to prevent light from passing through the outside of the light-emitting part.

[0017] The light-emitting component is electrically connected to the PCB board through a wiring harness. A wiring harness arrangement area for arranging the wiring harness is provided between the bottom shell and the sliding seat. A notch connecting the wiring harness arrangement area is provided on the protective cover to facilitate the arrangement of the wiring harness, avoid damage to the wiring harness during installation, and ensure that the light-emitting component can be powered on.

[0018] The wiring harness arrangement area includes a first threading port provided on the bottom shell, a first cavity provided in the slider and connected to the first threading port, and a second threading port provided on one side of the slider and connected to the slider cavity. The wiring harness arrangement area also includes a second cavity provided in the sliding seat, and a third threading port provided on one side of the sliding seat and connected to the second cavity.

[0019] The light-emitting component and the wiring harness follow the sliding of the slider, and the wiring harness part is limited to slide on the third threading port and the fourth threading port to prevent the wiring harness from shifting when sliding with the slider, causing the wiring harness to be torn off.

[0020] An open guide portion is provided on the third threading port, and guide surfaces are provided on both sides of the guide portion for guiding the wiring harness into the third threading port; the open guide portion facilitates the later disassembly and assembly of the wiring harness for maintenance.

[0021] The sliding stroke between the slider and the sliding seat includes the R gear sliding stroke, the N gear sliding stroke and the D gear sliding stroke.

[0022] The beneficial effects of the present invention are as follows:

[0023] The slider slides back and forth on the sliding seat via a sliding portion, forming a sliding shift mechanism. This eliminates the need for a transmission to push the shifter for shifting, reducing the overall size of the sliding shift mechanism and conserving driver space. The sliding shift mechanism also includes a control device. A position detector is provided on the control device corresponding to the reciprocating direction of the slider to detect the position of the slider. The position detector is at least one of a photoelectric sensor and a Hall effect sensor, preferably a photoelectric sensor. The use of a photoelectric sensor provides a more stable output signal, avoiding the influence of magnetic field conditions on the output signal of traditional Hall effect sensors.
