[0023] The following will describe in detail a specific embodiment of the utility model in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the description of 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.

For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0025] The directions or positional relationships indicated by terms such as "upper", "lower", "left", "right", "front", "back", "top", "bottom", "inside" and "outside" are based on the directions or positional relationships shown in the accompanying drawings, or are the directions or positional relationships in which the utility model product is usually placed when in use. They are only for the convenience of description and simplified description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the utility model.

[0026] The terms "first", "second", "third" and the like are merely used to distinguish elements of similar nature, and do not indicate or imply relative importance or a particular order.

[0027] The terms "comprises," "comprising," or any other variations thereof, are intended to cover a non-exclusive inclusion of the elements listed and may also include additional elements not expressly listed.

[0028] Please refer to Figure 1-5The embodiment of the utility model provides a multi-directional switch, including: a circuit board 10, on which a first touch switch and a plurality of second touch switches (not shown in the figure) for controlling the on and off of a multi-directional circuit are welded or integrated, and the plurality of second touch switches are arranged circumferentially along the first touch switch; a support seat 20, and the support seat 20 is located above the circuit board 10; a pressing component 30, the pressing component 30 includes a handle 31, a first pressing column 32 and a plurality of second pressing columns 33, the first pressing column 32 is vertically arranged on the first touch switch, and the plurality of second pressing columns 33 are vertically arranged on the plurality of second touch switches in a one-to-one correspondence, the length of the first pressing column 32 is greater than the length of any second pressing column 33, and the handle 31 is rotatably connected to the support seat 20; as the handle 31 rotates, the corresponding second pressing column 33 presses the corresponding second touch switch; when the handle 31 is pressed vertically, the first pressing column 32 presses the first touch switch.

[0029] Specifically, the circuit board 10 is integrated with a regularly arranged first touch switch and multiple second touch switches, and the first touch switch is located in the middle of the multiple second touch switches. Compared with the prior art in which multiple touch switches are arranged in a "T" shape, the multi-directional switch in this embodiment has the advantages of being easier to adjust the control direction and occupying a small space. Because the multiple second touch switches are distributed along the circumference of the first touch switch, the arrangement space of the first touch switch and the multiple second touch switches is reduced, and the multiple second touch switches have similar directionality, and the distance between any second touch switch and the first touch switch is always equal, which improves the convenience of switch control, shortens the control distance between the second touch switches, or between the second touch switches and the first touch switch, and avoids the complexity of structural design. The first pressing column 32 is arranged vertically with the first touch switch, and the second pressing column 33 is arranged vertically with the second touch switch, ensuring that when the pressing component 30 controls the pressing of the circuit board 10, the first touch switch and any second touch switch are always pressed vertically, which makes the control of the first touch switch and the second touch switch on the circuit board 10 more precise, and avoids the problem of not contacting the touch switch due to the rotation process that may occur when using the roller to press in the prior art.

[0030] Furthermore, the length of the first pressing column 32 is greater than the length of any second pressing column 33, and the end of the first pressing column 32 close to the circuit board 10 is flush with the ends of multiple second pressing columns 33 close to the circuit board 10, ensuring that the first pressing column 32 can be controlled first when the handle 31 is pressed vertically downward.

[0031] In one embodiment, it also includes a receiving box 40 for accommodating the circuit board 10, and a stop groove 41 is provided in the receiving box 40. The pressing assembly 30 also includes a locking column 34, and the locking column 34 is arranged parallel to the first pressing column 32. The stop groove 41 is arranged on the handle 31 corresponding to the locking column 34. When the handle 31 is pressed vertically, the stop groove 41 and the locking column 34 are clearance-matched.

[0032] Specifically, the locking column 34 cooperates with the stop groove 41 mainly to prevent the handle 31 from accidentally touching the first push column 32 when the handle 31 rotates to control the second push column 33. When the handle 31 is pressed vertically, the stop groove 41 and the locking column 34 cooperate with each other in a clearance, which can ensure that the locking groove and the locking column 34 do not affect the first push column 32.

[0033] Furthermore, the distance that the locking column 34 extends away from the handle 31 is greater than the length of the first push column 32, that is, the locking column 34 is closer to the bottom of the accommodating box 40 than the first push column 32, so that when the handle 31 presses down on the second push column 33, the locking column 34 forms a certain inclination angle and cannot vertically enter the locking groove, but is stuck in the locking groove. At this time, there is a certain distance between the first push column 32 and the first touch switch, thereby preventing accidental touch.

[0034] In other embodiments, the stop groove 41 may also be directly disposed corresponding to the first pressing column 32 without adding the locking column 34 . When the handle 31 is pressed vertically, the stop groove 41 and the first pressing column 32 are loosely matched.

[0035] In one embodiment, a plurality of stop blocks 42 are disposed in the accommodating box 40 , and the number of the stop slots 41 and the locking columns 34 are both plural, and each stop slot 41 is formed between two stop blocks 42 .

[0036] Specifically, a stop groove 41 is formed between the two stop blocks 42, which is conducive to the addition, reduction and replacement of the stop groove 41 and the locking column 34, reduces the difficulty of slotting in the accommodating box 40, and makes the structure simpler.

[0037] Furthermore, the number of stop blocks 42 is 4, and the number of locking columns 34 is 2. The 2 locking columns 34 are distributed on both sides of the first press column 32, and the 4 stop blocks 42 correspond to the 2 locking columns 34, that is, 2 stop blocks 42 and 1 locking column 34 are distributed on both sides of the first press column 32, so as to form a stop groove 41 and a locking column 34 on both sides of the first press column 32, thereby ensuring the balance, peace and stability of the structure.

[0038] In one embodiment, it also includes a first restoring member 50 and a plurality of second restoring members 60. The first restoring member 50 is disposed between the first pressing column 32 and the first touch switch, and is used to feedback the pressing force when the first pressing column 32 presses the first touch switch; the plurality of second restoring members 60 are disposed one by one between the plurality of second pressing columns 33 and the plurality of second touch switches, and are used to feedback the pressing force when the corresponding second pressing columns 33 press the second touch switches.

[0039] Specifically, the first reset member 50 and the second reset member 60 can be made of dome silicone, which can provide feedback of pressing force to the first push column 32 and the second push column 33, making it easier to determine whether the circuit board 10 is properly controlled, while also improving the operability of the multi-directional switch in the dark or while the car is driving.

[0040] Specifically, the first restoring member 50 and the plurality of second restoring members 60 are arranged on the silicone pad 70 , so that the first restoring member 50 and the second restoring member 60 are stacked on the circuit board 10 through the silicone pad 70 , thereby increasing the feedback capability of the force.

[0041] In one embodiment, the number of the second touch switches and the number of the second pressing columns 33 are both two, and the two second touch switches are arranged on both sides of the first touch switch.

[0042] Specifically, in the automotive field, a three-way control switch is more convenient for blind operation, and too many controllable directions may lead to structural complexity, which is not conducive to emergency control. When there are two second touch switches, arranging one second touch switch on each side of the first touch switch can ensure that the distance between the two is the shortest.

[0043] In one embodiment, the pressing assembly 30 further includes a plurality of buffer blocks 35, and the plurality of buffer blocks 35 are arranged on the handle 31 corresponding to the plurality of second pressing columns 33 one by one. When the handle 31 rotates, the handle 31 presses the corresponding second pressing columns 33 through the buffer blocks 35, so that the buffer blocks 35 buffer part of the pressing force of the second pressing columns 33.

[0044] Specifically, due to the height difference between the first push column 32 and the second push column 33, if the buffer block 35 is not provided between the second push column 33 and the handle 31, the second push column 33 and the handle 31 are always in a suspended state, and it is difficult for the operator to feel whether the handle 31 is controlled in place when operating the switch.

[0045] Please continue to refer to Figure 5 In one embodiment, the support seat 20 is provided with a mounting hole 21, and the handle 31 is provided with a rotating column 311, the rotating column 311 is passed through the mounting hole 21, the length of the mounting hole 21 is greater than the cross-sectional diameter of the rotating column 311, and the mounting hole 21 is clearance-matched with the rotating column 311 in the width direction.

[0046] Specifically, the length of the mounting hole 21 is greater than the cross-sectional diameter of the rotating column 311 , which reserves a movable space for pressing and restoring the handle 31 . The clearance fit between the mounting hole 21 and the rotating column 311 in the width direction can prevent displacement of the handle 31 when it is rotated.

[0047] In one embodiment, the support base 20 includes a partition plate 22 , and a plurality of guide holes 221 are formed in the partition plate 22 . The first pressing column 32 and the plurality of second pressing columns 33 extend toward the circuit board 10 through the guide holes 221 .

[0048] Specifically, the provision of the guide hole 221 is helpful to ensure the verticality of the first pressing column 32 and the second pressing column 33 when they are pressed downward toward the circuit board 10 .

[0049] Furthermore, both the first pressing column 32 and the second pressing column 33 are provided with a guide rib 36 , and the guide rib 36 and the guide hole 221 are clearance-matched, so that the cooperation between the two is more stable.

[0050] In one embodiment, a stopper 37 is disposed at one end of the second pressing post 33 facing away from the circuit board 10 to prevent the second pressing post 33 from completely passing through the guide hole 221 .

[0051] Specifically, the setting of the limiting block 37 on the one hand limits the transition of the second pressing column 33 into the guide hole 221 , and on the other hand increases the contact area between the second pressing column 33 and the handle 31 .

[0052] Furthermore, a stop block 37 is also disposed at one end of the first pressing post 32 facing away from the circuit board 10 to prevent the first pressing post 32 from completely passing through the guide hole 221 .

[0053] The utility model provides a multi-directional switch, which arranges a plurality of second touch switches around the circumference of a first touch switch so that the first touch switch and the plurality of second touch switches can be compactly distributed, which is beneficial to shortening the control distance of the multi-directional line during subsequent control. Furthermore, a first pressing column 32 is vertically arranged on the first touch switch, and a second pressing column 33 is vertically arranged on each second touch switch. The handle 31 is rotatably connected to the support base 20 above the circuit board 10. During the rotation of the handle 31, the pressure of the handle 31 can selectively press one of the multiple second pressing columns 33. The switch operator can control the handle 31 to rotate to a preset angle, and the corresponding second pressing column 33 will be pressed vertically toward the corresponding second touch switch. When the handle 31 is not rotated and is pressed vertically downward, the pressure of the handle 31 is transmitted to the first pressing column 32, and the first pressing column 32 is then pressed vertically toward the first touch switch. In this way, it can be ensured that the pressing component 30 can vertically press the first touch switch or the second touch switch no matter from which direction the circuit board 10 is controlled. The structural optimization improves the adjustability of the switch, and the vertical pressing direction ensures the accuracy of the pressing.

[0054] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model shall be subject to the attached claims.
