[0047] 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. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0048] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0049] In the description of the present invention, it should be understood that the terms "upper", "lower", "top", "bottom", "left" and "right" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the positions or elements referred to must have specific directions, be constructed and operated in specific directions, and therefore should not be understood as limitations of the present invention.

[0050] The utility model aims to provide a parking control switch to avoid the problem of unreasonable structural design of an electronic parking switch.

[0051] It should be noted that, in this embodiment, the X direction in the accompanying drawings is defined as the first direction, and the Y direction is defined as the second direction, and the second direction is the opposite direction of the first direction (for example, when the first direction is counterclockwise, the second direction is clockwise).

[0052] See also Figure 1 and Figure 2To achieve the above-mentioned purpose, the utility model provides a parking control switch, including a housing, a circuit module, a parking knob 3 and a touch assembly.

[0053] The circuit module is arranged in the accommodating cavity of the shell, and the circuit module can emit bright light after being triggered. In this embodiment, it is preferred that the circuit module emits the same bright light after being triggered. It can also be set according to actual conditions that different positions of the circuit module can emit different bright lights after being triggered to attract the attention of the operator. For example, the left side of the circuit module can emit red light after being triggered, and the right side of the circuit module can emit blue light after being triggered.

[0054] The parking knob 3 is rotatably mounted on the shell, and a decorative cover 33 is provided on the top of the parking knob 3, and a symbol mark 331 is provided on the top of the decorative cover 33. The trigger assembly is located between the circuit module and the parking knob 3, and includes a first rod 5 and a second rod 6 arranged at intervals. One end of the first rod 5 and the second rod 6 respectively abuts against different positions of the parking knob 3, and the other ends of both can trigger the circuit module; the first rod 5 is used to move when the parking knob 3 is rotated in a first direction to trigger the circuit module to achieve parking, and the second rod 6 is used to move when the parking knob 3 is rotated in a second direction to trigger the circuit module to achieve unlocking. The first rod 5 and the second rod 6 are also respectively provided with a light guide 53 that can transmit bright light to the top of the parking knob 3.

[0055] The first rod 5 and the second rod 6 are respectively abutted against different positions of the parking knob 3. When the parking knob 3 is rotated in a first direction, the first rod 5 abutting thereon moves downward to trigger the circuit module to achieve parking. At the same time, the bright light emitted by the circuit module is transmitted along the light guide portion 53 to the decorative surface cover 33 on the top of the parking knob 3, so that the symbol mark 331 is illuminated to remind the operator that the parking state has been reached. When the parking knob 3 is rotated in a second direction, the second rod 6 abutting thereon moves downward to trigger the circuit module to achieve unlocking. At the same time, the bright light emitted by the circuit module is transmitted along the light guide portion 53 to the decorative surface cover 33 on the top of the parking knob 3, so that the symbol mark 331 is illuminated to remind the operator that the parking state has been reached. By integrating the light guide portion 53 into the first rod 5 and the second rod 6, the number of parts in the electronic parking switch is reduced, so that the assembly of each part is simple, which is beneficial to the release of space while reducing the production cost, and can avoid the problem of unreasonable structural design of the electronic parking switch.

[0056] See also Figure 3In this embodiment, the first rod 5 and the second rod 6 are also provided with a shift rod 51 and a top rod 52. The top of the shift rod 51 is provided with an end for abutting the parking knob 3. Through the contact between the end and the parking knob 3, when the parking knob 3 rotates in the first direction and the second direction, the shift rod 51 can be driven to move downward, thereby driving the top rod 52 extending vertically and connected to the bottom of the shift rod 51 to move downward and contact the circuit module, so that the bright light emitted by the circuit module is transmitted along the light guide part 53. The two light guide parts 53 are respectively located on the opposite sides of the two shift rods 51, and the two light guide parts 53 are spaced apart to prevent mutual friction between the first rod 5 and the second rod 6 during the downward movement. The first rod 5 and the second rod 6, both including the light guide part 53, have the same structure, which is convenient for processing and installation.

[0057] In another embodiment, the light guide portion 53 may also be disposed on only one of the first rod 5 and the second rod 6 , which can also achieve the transmission of bright light to the top of the parking knob 3 .

[0058] It can be understood that the shell includes a shell body 1 and a base 2 which can form a accommodating cavity after being connected. A bracket 11 is provided on the top of the shell body 1, and a baffle 111 for the top rod 52 to movably pass through and a guide groove 113 for the vertical movement of the gear lever 51 are provided inside the bracket 11. The gear lever 51 is provided with a guide surface 511 that can slide with the guide groove 113. The guide surface 511 is located on both sides of the bottom of the gear lever 51. The distance between the two guide surfaces 511 is slightly smaller than the distance between the guide groove 113 and the two inner walls of the guide surface 511, so that the gear lever 51 can move downward along the extension direction of the guide groove 113 when the parking knob 3 is rotated. At the same time, the guide surface 511 can be set as a vertical surface with a smaller area to reduce the friction during the movement of the gear lever 51 and increase the service life of the gear lever 51.

[0059] In addition, an elastic member 7 is provided between the bottom of the shift rod 51 and the baffle 111, and the elastic member 7 is sleeved on the outer periphery of the push rod 52 to restore the first rod 5 and the second rod 6 that have been moved downward. When the parking knob 3 is rotated by an external force, the shift rod 51 is moved downward by the force of the parking knob 3. At this time, the elastic member 7 is compressed and is in a force storage state; when the external force is removed, the elastic member 7 in the force storage state drives the end of the shift rod 51 to lift the parking knob 3 in the opposite direction, so that the parking knob 3 returns to its original position, wherein the elastic member 7 is preferably a spring, the diameter of the spring is larger than the diameter of the push rod 52, and smaller than the width of the bottom of the shift rod 51, so as to realize the abutment process.

[0060] Preferably, the shift lever 51 has a "triangle" structure, that is, the above-mentioned end and the two guide surfaces 511 are respectively located at the top angle and two bottom angles of the triangle, and the top angle is an acute-angle structure to facilitate the abutment process of the end. A plate body 512 is provided on the side facing each other of the two shift levers 51, and the light guiding part 53 is connected to the plate body 512 through a connecting piece 513. A limiting groove 114 is provided on the top of the side wall of the guide groove 113 for the connecting piece 513 to movably pass through, so that the light guiding part 53 can move vertically with the connected shift lever 51.

[0061] In this embodiment, the circuit module includes a circuit board assembly 41, a wiring terminal 42, a micro switch and an LED lamp 45. The micro switch is arranged on the top of the circuit board assembly 41, including a first micro switch 43 and a second micro switch 44 arranged at intervals, and a small hole for exposing the trigger points of the first micro switch 43 and the second micro switch 44 to the bottom of the corresponding top rod 52 is provided on the top of the housing body 1, and the first micro switch 43 is located below the top rod 52 in the first rod 5, and the second micro switch 44 is located below the top rod 52 in the second rod 6; the LED lamp 45 is arranged on the top of the circuit board and between the first micro switch 43 and the second micro switch 44; the wiring terminal 42 is arranged at the bottom of the circuit board assembly 41, and is used to send a signal to the circuit board assembly 41 when either of the first micro switch 43 and the second micro switch 44 is turned on.

[0062] The light guide portion 53 includes a first side surface 531 connected to the connector 513 and a second side surface 532 facing away from the connector 513. The second side surface 532 is a vertical surface, and the distance between the first side surface 531 and the second side surface 532 gradually decreases from top to bottom. The smaller end of the light guide portion 53 is closer to the LED lamp 45, so that when either the first rod 5 or the second rod 6 triggers the micro switch, the wiring terminal 42 sends an electrical signal to the circuit board assembly 41, so that the LED lamp 45 emits bright light that propagates upward along the smaller end of the light guide portion 53.

[0063] Specifically, when the first rod 5 triggers the first micro switch 43, the terminal 42 sends a first electrical signal to the circuit board assembly 41, so that the LED lamp 45 emits a bright light; when the second rod 6 triggers the second micro switch 44, the terminal 42 sends a second electrical signal to the circuit board assembly 41, so that the LED lamp 45 emits a bright light.

[0064] In this embodiment, cylindrical protrusions 112 are provided on both sides of the bracket 11, and through holes 32 adapted to the protrusions 112 are provided on both sides of the parking knob 3. The protrusions 112 are assembled to the corresponding through holes 32, so that the bracket 11 and the parking knob 3 are snapped together. The cross-section of the through hole 32 perpendicular to the axial direction of the protrusion 112 is circular, so that the parking knob 3 can rotate around the axis of the protrusion 112. When the parking knob 3 rotates, the parking knob 3 presses the first rod 5 or the second rod 6 to move downward, and the elastic member 7 is also compressed. At this time, the parking knob 3 is subjected to the reaction force of the compressed elastic member 7, which can increase the operator's feel when turning the parking knob 3.

[0065] Among them, the parking knob 3 is also provided with a guide portion 31, and the guide portion 31 includes a first guide portion 311 and a second guide portion 312 arranged at intervals. The first guide portion 311 is provided with a first arc surface and a second arc surface connected to each other and is located at the top of the end of the first rod 5. During the rotation of the parking knob 3, the first arc surface and the second arc surface with different structures are in contact with the end of the gear lever 51 to drive the gear lever 51 to maintain its original position and move downward. The second guide portion 312 is provided with a third arc surface and a fourth arc surface connected to each other and is located at the top of the end of the second rod 6. The end is a rounded structure to reduce the wear of the end and the above-mentioned arc surface.

[0066] See also Figure 4 and Figure 5 When the parking knob 3 is in the original position, the first rod 5 abuts against the first arc surface, the second rod 6 abuts against the fourth arc surface, and neither micro switch is triggered; when the parking knob 3 rotates along the first direction, the first rod 5 abuts against the second arc surface, the first rod 5 moves downward, and the first micro switch 43 is triggered, the second rod 6 still abuts against the fourth arc surface, and the height of the second rod 6 remains unchanged; when the parking knob 3 rotates along the second direction, the first rod 5 abuts against the first arc surface, the second rod 6 abuts against the third arc surface, the second rod 6 moves downward, and the second micro switch 44 is triggered.

[0067] It should be noted that the first rod 5 and the second rod 6 are both integrated structures. By integrating the gear lever 51 that can provide a hand feel, the top rod 52 that triggers the micro switch, and the light guiding part 53 that can guide bright light, it is possible to reduce parts, reduce costs, simplify the assembly process, and improve production efficiency. The first rod 5 and the second rod 6 are both made of transparent plastic material, which can improve the light transmission efficiency and reduce the power of the LED accordingly, thereby achieving the effect of energy saving and emission reduction.

[0068] The first guide portion 311 and the second guide portion 312 are preferably provided with three snap-in blocks 313 on the opposite sides thereof, and the decorative surface cover 33 is provided with three snap-in grooves 332 adapted to the three snap-in blocks 313 on both sides, so that the decorative surface cover 33 can be fixed relative to the first guide portion 311 and the second guide portion 312 while facilitating alignment during the installation process, so as to avoid the situation where a single snap-in block 313 and the snap-in groove 332 are not snapped into place.

[0069] It can be understood that a plurality of protrusions 21 are provided on both sides of the base 2, and a plurality of card slots 12 connected to the accommodating cavity are provided on both sides of the shell body 1. Preferably, the number of protrusions 21 and card slots 12 on a single side are both three, so that after the protrusions 21 are snapped into the corresponding card slots 12, the shell body 1 and the base 2 are snapped and fixed. The base 2 is also provided with a positioning groove 22 and a convex ridge 23. The positioning groove 22 is arranged inside the base 2 for positioning the installed terminal 42 to prevent the terminal 42 from moving after installation. The convex ridge 23 is arranged on the side wall of the base 2, and the convex ridge 23 can abut against the bottom of the shell to support the shell.

[0070] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0071] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

The above examples are only used to help understand the method and core ideas of the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the utility model.
