Description

Technical Field

[0001] This utility model relates to the field of automotive switch technology, and in particular to a multifunctional knob structure. Background Technology

[0002] With the trend of intelligent development in automobiles, cars are equipped with more and more functions, and each function needs to be controlled by a corresponding switch to turn it on and off, resulting in an increasing number of switches.

[0003] There are two types of switches: touch switches and physical switches. Physical switches are the most commonly used due to their low cost and high reliability. However, physical switches require a certain amount of space, and the space inside a car is limited. The increase in the number of switches increases the design difficulty of the car's interior layout. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art by providing a multi-functional knob structure that integrates knob, pressing and toggle functions. Different functions can be achieved by operating the same knob in different ways, thereby reducing the number of switches in the vehicle.

[0005] The technical solution of this utility model is as follows: A multifunctional knob structure includes a housing and a knob. The housing contains a first circuit board, a second circuit board, an encoder, and a swing base. The encoder is mounted on the second circuit board, which is connected to the first circuit board. The encoder includes a base and a movable shaft. The knob is connected to the movable shaft and can drive the movable shaft to rotate circumferentially and slide axially relative to the base. The first circuit board has a first micro switch and a second micro switch. The swing base is hinged to the housing and covers the second circuit board. The swing base has a connecting sleeve, and the movable shaft passes through the connecting sleeve so that when the knob swings, it drives the swing base to swing, thereby triggering the first micro switch or the second micro switch.

[0006] Using the above technical solution, the knob can be rotated, pressed down, and tossed. The encoder enables the knob to rotate 360° and press down. When the knob is tossed forward, it drives the connecting sleeve to move synchronously, which in turn drives the swing base to swing. This causes one end of the swing base to move downward and trigger the first micro switch. When it is tossed backward, the swing base triggers the second micro switch. This knob structure can be used in multi-functional applications such as air conditioning panels, air conditioning vents, and rearview mirror adjustments.

[0007] A further feature of this invention is that a push rod is provided inside the housing above the two microswitches. The upper end of the push rod abuts against the swing seat, so as to drive the push rod to slide axially and trigger the corresponding microswitch when the swing seat swings.

[0008] With the above-mentioned further settings, sufficient triggering force can be provided during operation, while maintaining good tactile feel and stability, thus better triggering the micro switch.

[0009] A further feature of this invention is that it includes conductive rubber, which is placed above the first micro switch and the second micro switch, and the conductive rubber has elastic protrusions corresponding to the contact positions of the micro switches.

[0010] The above-mentioned further settings can provide protection, preventing dust, water, and other contaminants from affecting the microswitch, and also allow for resetting.

[0011] A further feature of this invention is that the housing is provided with a hinge seat, the hinge seat is provided with a hinge shaft, the swing seat is provided with a hinge hole, and the hinge shaft is located in the hinge hole, so that the swing seat swings relative to the hinge shaft.

[0012] With the above-mentioned further design, the structure is simple and easy to install, so as to realize the tossing of the knob. The hinge base can be installed on the housing or on the second circuit board by screws. The hinge hole can also be set on the hinge base, and the hinge shaft is set on the swing base.

[0013] A further feature of this invention is that: a guide seat is provided inside the housing corresponding to the two push rod positions, and a guide groove is provided inside the guide seat. The push rod is slidably disposed in the guide groove, and a limiting part is provided at the lower end of the push rod to prevent the push rod from disengaging from the guide seat.

[0014] The above-mentioned further design makes the sliding of the push rod more stable, preventing the push rod from misaligning with the micro switch when it slides down under the pressure of the swing seat. The setting of the limit part can prevent the push rod from disengaging from the guide seat when it returns to its original position.

[0015] A further improvement of this utility model is as follows: the housing includes a separate base and an outer cover, the outer cover is provided outside the base, the first circuit board, the second circuit board and the swing seat are all located inside the base, and the outer periphery of the base is also provided with several connecting pieces.

[0016] The above-mentioned design is further improved by adopting a split design, which facilitates the installation of each circuit board and the swing base, and also protects the circuit boards from exposure, making it more aesthetically pleasing. The base is installed and fixed to the car via connecting pieces, resulting in a sturdy structure. Attached Figure Description

[0023] like Figure 1-5As shown, a multifunctional knob structure includes a housing 1 and a knob 2. The housing 1 contains a first circuit board 3, a second circuit board 4, an encoder 5, and a swing base 6. The encoder 5 is mounted on the second circuit board 4, which is connected to the first circuit board 3. The encoder 5 includes a base 51 and a movable shaft 52. The knob 2 is connected to the movable shaft 52 and can drive the movable shaft 52 to rotate circumferentially and slide axially relative to the base 51. The first circuit board 3 has a first micro switch 31 and a second micro switch 32. The swing base 6 is hinged to the housing 1 and covers the second circuit board 4. The swing base 6 has a connecting sleeve 61. The movable shaft 52 passes through the connecting sleeve 61 so that when the knob 2 swings, it drives the swing base 6 to swing, thereby triggering the first micro switch 31 or the second micro switch 32. The movable shaft 52 can rotate circumferentially and slide axially relative to the connecting sleeve 61. The knob 2 can rotate, press down, and toggle. The encoder 5 enables the knob 2 to rotate. The knob 2 features a 360° rotation function, while the encoder 5 enables the knob 2 to be pressed. When the knob 2 is turned forward, it drives the connecting sleeve 61 to move synchronously, which in turn drives the swing base 6 to swing. This causes one end of the swing base 6 to move downward, triggering the first micro switch 31. When turned backward, the swing base 6 triggers the second micro switch 32. This knob 2 structure can be applied to various multi-functional applications such as air conditioning panels, air conditioning vents, and rearview mirror adjustments. It also includes conductive rubber 10, which covers the first micro switch 31 and the second micro switch 32.

[0024] Inside the housing 1, above the two microswitches, there is a push rod 7. The upper end of the push rod 7 abuts against the swing seat 6, so that when the swing seat 6 swings, the push rod 7 is driven to slide axially to trigger the corresponding micro switch. During operation, it can provide sufficient triggering force while maintaining good tactile feel and stability, and better triggering the micro switch. When the knob 2 returns to the original position, the push rod 7 can be reset by the reset of the micro switch contact, or by the elastic protrusion on the conductive rubber. Inside the housing 1, there is a guide seat 8 corresponding to the two push rods 7. The guide seat 8 has a guide groove. The push rod 7 is slidably disposed in the guide groove, and the lower end of the push rod 7 has a limiting part 71 to prevent the push rod 7 from disengaging from the guide seat 8, making the push rod 7 more stable when sliding, and preventing the push rod 7 from being misaligned with the micro switch when it slides down under the pressure of the swing seat 6. The setting of the limiting part 71 can prevent the push rod 7 from disengaging from the guide seat 8 when it returns to the original position.

[0025] The housing 1 is provided with a hinge seat 9, and the hinge seat 9 is provided with a hinge shaft 91. The swing seat 6 is provided with a hinge hole 62, and the hinge shaft 91 is located in the hinge hole 62, so that the swing seat 6 swings relative to the hinge shaft 91. The structure is simple and easy to install, so as to realize the toggle of the knob 2. The hinge seat 9 can be installed on the housing 1 or on the second circuit board 4 by screws. The hinge hole 62 can also be provided on the hinge seat 9, and the hinge shaft 91 is provided on the swing seat 6.

[0026] The housing 1 includes a separate base 11 and an outer cover 12. The outer cover 12 covers the base 11. The base 11 has an open-top accommodating cavity. The first circuit board 3, the second circuit board 4, and the swing seat 6 are all located inside the base 11. The outer periphery of the base 11 is also provided with several connecting pieces 111. The separate arrangement facilitates the installation of each circuit board and the swing seat 6, and also protects the circuit boards from exposure, making it more aesthetically pleasing. The base 11 is installed and fixed to the car through the connecting pieces 111, resulting in a sturdy structure.
