[0023] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are merely used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Those skilled in the art can make adjustments as needed to adapt to specific applications. For example, although the cross-sections of the first limiting body and the second limiting body are described in the specification as being n-shaped, the present invention can obviously adopt various other forms, such as a rectangle, etc., as long as they have the effect of limiting the first push rod and the second push rod.
[0024] It should be noted that in the description of the present invention, terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings. These are merely for ease of description and are not intended to indicate or imply that the device or element described must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0025] Furthermore, it should be noted that, in the description of the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.
[0026] First refer to Figure 1The working principle of the switch in the prior art is that when an external force is applied to the first end 11 of the push rocker 1, the push rocker 1 presses the first push rod 2, so that the first push rod 2 touches the touch switch at the first end 11 to connect the circuit. When the external force is released, the first elastic member 4 resets the first push rod 2 to disconnect the circuit. When an external force is applied to the second end 12 of the push rocker 1, the push rocker 1 presses the second push rod 3, so that the second push rod 3 touches the touch switch at the second end 12 to connect the circuit. When the external force is released, the second elastic member 5 resets the second push rod 3. , realizing circuit disconnection, wherein the factors limiting the position of the pressing rocker 1 include the height (H4) of the first elastic member 4 and the height (H2) of the second elastic member 5, as well as the height (H3) from the top of the first push rod 2 to the top of the first elastic member 4 and the height (H1) from the top of the second push rod 3 to the top of the second elastic member 5. The number of tolerance dimension chains reaches 4, wherein the tolerance dimension chain described in the present invention is the overall size or partial size of the component that affects the position of the pressing rocker 1, such as the height (H4) of the first elastic member 4 and the height (H3) from the top of the first push rod 2 to the top of the first elastic member 4.
[0027] In order to solve the problem of zero position deviation and shaking of switches in existing vehicles due to dimensional deviation, the present invention provides three embodiments of switches for vehicles. The technical solutions of the three embodiments are as follows:
[0028] like Figure 2 、 Figure 3 and Figure 4 As shown, the switch of the present invention is a toggle switch, and its working principle is as follows: when an external force is applied to the first end 11 of the push rocker 1, the push rocker 1 will press the first push rod 2, so that the first push rod 2 touches the touch switch at the first end 11 to connect the circuit; when the external force is released, the first elastic member 4 resets the first push rod 2 to disconnect the circuit; when an external force is applied to the second end 12 of the push rocker 1, the push rocker 1 will press the second push rod 3, so that the second push rod 3 touches the touch switch at the second end 12 to connect the circuit; when the external force is released, the second elastic member 5 resets the second push rod 3 to disconnect the circuit; wherein, the first limiter 6 and the second limiter 7 limit the movement range of the first push rod 2 and the second push rod 3, which can prevent the first push rod 2 and the second push rod 3 from shaking within the first limiter 6 and the second limiter 7.
[0029] Implementation method 1 of the switch for a vehicle: Continue to refer to Figure 2The switch includes a push rocker 1, a first push rod 2, a second push rod 3, a first elastic member 4, a second elastic member 5 and a shell. The push rocker 1 is pivotally connected to the shell, and the position where the push rocker 1 is pivotally connected to the shell is set between the first push rod 2 and the second push rod 3; the switch also includes a first limiter 6 and a second limiter 7. The first limiter 6 and the second limiter 7 are fixedly arranged, the first push rod 2 passes through the first limiter 6 and abuts against the bottom of the first end 11 of the push rocker 1, and the second push rod 3 passes through the second limiter 7 and abuts against the bottom of the second end 12 of the push rocker 1; the first elastic member 4 is fixedly arranged and connected to the bottom of the first push rod 2, the first push rod 2 abuts against the first limiter 6, and the first elastic member 4 is in a compressed state, the second elastic member 5 is fixedly arranged and connected to the bottom of the second push rod 3, the second push rod 3 abuts against the second limiter 7, and the second elastic member 5 is in a compressed state.
[0030] The advantages of the above-mentioned setting method are: the first push rod 2 is in contact with the first limiting body 6, and the first elastic member 4 is in a compressed state; and the second push rod 3 is in contact with the second limiting body 7, and the second elastic member 5 is in a compressed state. That is, the first limiting body 6 and the second limiting body 7 limit the movement of the first push rod 2 and the second push rod 3 in the direction of pressing the rocker 1, so that the first push rod 2 is always in contact with the first limiting body 6, and the second push rod 3 is always in contact with the second limiting body 7. At this time, no matter how much elastic force the first elastic member 4 and the second elastic member 5 release, they cannot push the first push rod 2 and the second push rod 3 upward. Compared with the above Figure 1 Compared with the prior art, the present invention adopts a design in which the first push rod 2 and the second push rod 3 are always in contact with the first limit body 6 and the second limit body 7, so that the tolerance chain of the switch system is not affected by the height of the first elastic member 4 and the second elastic member 5, thereby reducing the number of tolerance dimension chains to 2, thereby forming better dimensional control, reducing zero position offset, ensuring the position accuracy of the switch, and avoiding its shaking.
[0031] As a preferred embodiment of the above embodiment, the cross-sectional shape of the first limiting body 6 and the second limiting body 7 is N-shaped, the first push rod 2 is slidably connected to the inner wall of the first limiting body 6, and the second push rod 3 is slidably connected to the inner wall of the second limiting body 7, the first push rod 2 is provided with a first protrusion 21, and the second push rod 3 is provided with a second protrusion 31, the first protrusion 21 abuts against the bottom of the first limiting body 6, and makes the first elastic member 4 in a compressed state, the second protrusion 31 abuts against the bottom of the second limiting body 7, and makes the second elastic member 5 in a compressed state.
[0032] The advantage of the above-mentioned setting method is that the cross-sectional shape of the first limit body 6 and the second limit body 7 is an N-shaped design, which can make the contact area between the first push rod 2 and the second push rod 3 and the first limit body 6 and the second limit body 7 larger, thereby ensuring that the first push rod 2 and the second push rod 3 do not shift relative to the pressing direction, thereby avoiding the first push rod 2 and the second push rod 3 from shaking in the first limit body 6 and the second limit body 7, and further ensuring the stability of the switch. Since the first protrusion 21 abuts against the bottom of the first limit body 6 and the second protrusion 31 abuts against the bottom of the second limit body 7, the number of tolerance chains of the switch system is not related to the height of the first elastic member 4 and the second elastic member 5, so that the number of dimension chains is reduced, thereby forming better dimension control, and through dimension design, reducing zero position offset, ensuring the position accuracy of the switch, and avoiding switch shaking.
[0033] Implementation method 2 of the switch for a vehicle: Continue to refer to Figure 3 The switch includes a push rocker 1, a first push rod 2, a second push rod 3, a first elastic member 4, a second elastic member 5 and a shell. The push rocker 1 is pivotally connected to the shell, and the position where the push rocker 1 is pivotally connected to the shell is set between the first push rod 2 and the second push rod 3; the switch also includes a first limiter 6 and a second limiter 7. The first push rod 2 passes through the first limiter 6 and abuts against the bottom of the first end 11 of the push rocker 1, and the second push rod 3 passes through the second limiter 7 and abuts against the bottom of the second end 12 of the push rocker 1, and the second push rod 3 abuts against the second limiter 7; the first elastic member 4 is fixedly arranged and connected to the bottom of the first push rod 2, The second elastic member 5 is fixedly arranged and connected to the bottom of the second push rod 3. The difference from the first embodiment of the switch for the vehicle is that: the pre-pressure on the second elastic member 5 and the first elastic member 4 can make the torque of the second push rod 3 acting on the second end 12 of the pressing rocker 1 greater than the torque of the first push rod 2 acting on the first end 11 of the pressing rocker 1, and in the pressing direction of the first push rod 2, a movable gap 8 is left between the first limiter 6 and the first push rod 2, wherein the first limiter 6 and the second limiter 7 can be connected to the shell in an integral manner, which can simplify the production process, or can be connected in a split manner, which is convenient for production operation.
[0034] Since the torque of the second push rod 3 of the present invention acting on the second end 12 of the pressing rocker 1 is greater than the torque of the first push rod 2 acting on the first end 11 of the pressing rocker 1, without any restrictions, the second push rod 3 will lift the pressing rocker 1. According to the principle of lever, the first push rod 2 will be pressed, thereby turning on the touch switch at the first end 11. Therefore, the present invention limits the movement of the second push rod 3 in the direction of the pressing rocker 1 by abutting the second push rod 3 with the second limiter 7, thereby avoiding triggering the touch switch at the first end 11. Furthermore, due to the existence of tolerance, in the present invention, in the pressing direction of the first push rod 2, an active gap 8 is left between the first limiting body 6 and the first push rod 2, so that under the action of the elastic force of the first elastic member 4, the first push rod 2 can be urged to move in the direction of the pressing rocker 1 to fill this active gap 8. Then, by only accurately designing the size of the second push rod 3, the second push rod 3 is always fitted with the pressing rocker 1, so that the pressing rocker 1 is kept at zero position. At this time, if the first push rod 2 and the pressing rocker 1 do not fit together due to the existence of tolerance, the setting of the active gap 8 can make The first push rod 2 moves upward until it is in contact with the first end 11 of the push rocker 1, thereby forming a very stable position, ensuring the accuracy of the switch position, avoiding shaking of the switch, and improving the product texture. In other words, the height of the movable gap 8 can make up for the tolerance height between the first push rod 2 and the push rocker 1. In addition, since the torque of the second push rod 3 acting on the second end 12 of the push rocker 1 is greater than the torque of the first push rod 2 acting on the first end 11 of the push rocker 1, the second push rod 3 cannot be pressed downward, thereby preventing the touch switch from being triggered.
[0035] This arrangement enables the second end 12 of the push rocker 1 to form a very stable position, which becomes the positioning reference of the entire switch system, and reduces the bilateral offset of the push rocker 1 at the zero position to a unilateral offset, that is, the stable position of the push rocker 1 depends on the final top position of the second push rod 3 (due to the existence of asymmetric torque, the push rocker 1 is aligned with the top position of the second push rod 3 when in the final stable state). Therefore, the tolerance dimension chain of the switch system is mainly related to the machining error of the structural dimension on the side of the second push rod 3, and the tolerance dimension chain on the side of the first push rod 2 is reduced to 0, that is, the machining error on the side of the first push rod 2 will no longer cause the overall structure to deviate. Figure 3To give an example, the precise control of size only involves the length of A, that is, taking the bottom of the push rocker 1 as the reference plane, the height from the reference plane to the bottom of the second limiter 7, and the precise size design of the second push rod 3 of this part is sufficient, while the height restriction of the movable gap 8 is relatively loose, and it can be greater than or equal to the tolerance that needs to be compensated. Therefore, the size design of the component that determines the size of the movable gap is relatively loose, and does not need to be precisely controlled. Therefore, it can be ignored as 0, and the final size tolerance chain is reduced to 1. Therefore, this setting method can form better size control, reduce zero position offset, and ensure the accuracy of the switch position.
[0036] As a preferred embodiment of the above embodiment, the first push rod 2 is provided with a first protrusion 21, which is disposed between the first limiting body 6 and the first elastic member 4, with a movable gap 8 being left between the first protrusion 21 and the first limiting body 6. The second push rod 3 is provided with a second protrusion 31, which abuts the second limiting body 7 via the second protrusion 31. In other words, the elastic force of the first elastic member 4 forces the first protrusion 21 to move toward the pressing rocker 1, thereby filling the movable gap 8 and ensuring that the first push rod 2 and the second push rod 3 are always in contact with the pressing rocker 1, ensuring positional accuracy and maintaining a stable state.
[0037] There are many implementations for setting the movable gap 8 between the first protrusion 21 and the first limiting body 6 , and the present invention is described with the following two implementations as examples.
[0038] Continue to refer to Figure 3 In the first configuration, the first push rod 2 and the second push rod 3 have the same design dimensions. Taking the bottom of the push rocker 1 as the reference plane, the height from the bottom of the first limiter 6 to the reference plane is smaller than the height from the bottom of the second limiter 7 to the reference plane. The height difference is the height of the movable gap 8.
[0039] The height from the bottom of the first limiting body 6 to the reference surface is Figure 3 The height from the bottom of the second limiting body 7 to the reference plane is A in the figure, and the height of the movable gap 8 is G = AC, which is Figure 3 The height from the first protrusion 21 to the bottom of the first limiter 6, that is, after determining the height of the movable gap 8, the dimensions of the first limiter 6 and the second limiter 7 can be designed. At this time, the first push rod 2 and the second push rod 3 use the same push rod, which greatly improves the consistency of the push rod components, improves the dimensional stability of the system, and reduces production costs.
[0040] Continue to refer to Figure 4In the second configuration, the first push rod 2 and the second push rod 3 have different dimensions, and the first protrusion 21 and the second protrusion 31 have different thicknesses and positions. The second protrusion 31 is positioned between the second stopper 7 and the second elastic member 5. With the bottom of the rocker 1 as the reference plane, the height from the reference plane to the top of the first protrusion 21 is greater than the height from the reference plane to the top of the second protrusion 31. This height difference is the height of the movable gap 8.
[0041] The height from the reference surface to the top of the first protrusion 21 is Figure 4 The height from the reference plane to the top of the second protrusion 31 is B in the figure, the height G of the movable gap 8 is BA, that is, after the height of the movable gap 8 is determined, the height of the first protrusion 21 can be designed, so that the size of B can be controlled by the height of the first protrusion 21.
[0042] Furthermore, the cross-sectional shape of the first limiting body 6 and the second limiting body 7 is N-shaped, the first push rod 2 is slidably connected to the inner wall of the first limiting body 6, and the second push rod 3 is slidably connected to the inner wall of the second limiting body 7.
[0043] The advantage of the above-mentioned setting method is that the cross-sectional shape of the first limit body 6 and the second limit body 7 is an N-shaped design, which can make the contact area of the first push rod 2 and the second push rod 3 with the first limit body 6 and the second limit body 7 larger, thereby avoiding the first push rod 2 and the second push rod 3 from shaking. Taking the first push rod 2 as an example, from the cross-sectional view, in the pressing direction, the point where the first push rod 2 contacts the first limit body 6 forms a longer straight line, thereby ensuring that the first push rod 2 does not deviate relative to the pressing direction, thereby avoiding the shaking of the first push rod 2 in the first limit body 6, and further ensuring the stability of the switch.
[0044] Furthermore, the point where the push rocker 1 is pivotally connected to the housing is located in the middle of the push rocker 1. This arrangement can eliminate the influence of the push rocker 1's own weight on its balance. In addition, it is more convenient to design asymmetric torques, that is, the points where the first push rod 2 and the second push rod 3 act on the two ends of the push rocker 1 are at the same distance from the pivotal connection point, and thus the lever arms are the same. In this case, different preloads can be designed using the first elastic member 4 and the second elastic member 5 to achieve different torque sizes at both ends. As a preferred embodiment, the preload of the second elastic member 5 is 0.5N higher than the preload of the first elastic member 4, thereby ensuring the accuracy of the switch position without affecting the pressing feel.
[0045] Furthermore, the push rocker 1 includes a toggle key 13 and a rocker body 14. The toggle key 13 is provided on the rocker body 14. The first push rod 2 passes through the first limiter 6 and abuts against the bottom of the first end 11 of the rocker body 14. The second push rod 3 passes through the second limiter 7 and abuts against the bottom of the second end 12 of the rocker body 14. The provision of the toggle key 13 facilitates user operation and improves the user experience. As a preferred embodiment, the outer side of the toggle member is covered with a decorative surface to make the switch more beautiful and also provide anti-slip properties.
[0046] Embodiment 3 of a switch for a vehicle: This embodiment is a variation of embodiment 2 of a switch for a vehicle, specifically: the switch includes a push rocker 1, a first push rod 2, a second push rod 3, a first elastic member 4, a second elastic member 5, and a housing. The push rocker 1 is pivotally connected to the housing, and the position where the push rocker 1 is pivotally connected to the housing is set between the first push rod 2 and the second push rod 3; the switch also includes a first limiter 6 and a second limiter 7, the first limiter 6 and the second limiter 7 are fixedly arranged, and the first push rod 2 passes through the first limiter 6 and abuts against the bottom of the first end 11 of the push rocker 1. The second push rod 3 passes through the second limiter 7 and abuts against the bottom of the second end 12 of the pressing rocker 1, and the second push rod 3 abuts against the second limiter 7; the first elastic member 4 is fixedly arranged and connected to the bottom of the first push rod 2, and the second elastic member 5 is fixedly arranged and connected to the bottom of the second push rod 3. The pre-pressure on the second elastic member 5 and the first elastic member 4 can make the torque of the second push rod 3 acting on the second end 12 of the pressing rocker 1 greater than the torque of the first push rod 2 acting on the first end 11 of the pressing rocker 1. The deformation is that: the first push rod 2 is a cylindrical rod without a boss (not shown in the figure).
[0047] Since the first push rod 2 is a cylindrical rod without a boss, the first limiter 6 cannot limit the movement of the first push rod 2 in the pressing direction. Under the action of the first elastic member 4, the first push rod 2 can be pushed to move always in the direction of the pressing rocker 1 until it is blocked by a torque greater than the torque acting on the pressing rocker 1 by the first push rod 2. Therefore, this setting method can ensure that the first push rod 2 and the second push rod 3 are always in contact with the pressing rocker 1, and the second push rod 3 cannot be pressed downward, so that the position accuracy and stability of the switch can be guaranteed only by the precise size design of the second push rod 3, and it can be avoided from shaking. In addition, the cylindrical rod has a simple structure, is easy to produce, and can save production costs.
[0048] The first elastic member 4 and the second elastic member 5 of the present invention may be rubber pads or springs, etc., as long as they are elastic and can move the first push rod 2 and the second push rod 3 in the direction of pressing the rocker 1.
[0049] In summary, the switch of the present invention reduces the zero position offset of the switch to the greatest extent by means of a design in which the first protrusion 21 and the second protrusion 31 are always in contact with the first limit body 6 and the second limit body 7; by setting the asymmetric torque on both sides of the pressing rocker 1, the bilateral offset of the switch at zero position is reduced to a unilateral offset, and the number of dimension chains is reduced to half of the original, thereby ensuring a more precise position and being able to ensure that the switch is always in a stable state.
[0050] It should be noted that the above-mentioned embodiments are only used to illustrate the principles of the present invention and are not intended to limit the scope of protection of the present invention. Without departing from the principles of the present invention, those skilled in the art can adjust the above-mentioned structure so that the present invention can be applied to more specific application scenarios.
[0051] For example, in a replaceable embodiment, an elastic snap joint can be provided on the first push rod 2, and a snap groove compatible with it can be provided on the first limiting body 6. The distance between the elastic snap joint and the snap groove is the movable gap 8. When the first push rod 2 moves in the direction of pressing the rocker 1, the snap groove can limit the first push rod 2. When the first push rod 2 moves in the pressing direction, the elastic snap joint on the first push rod 2 can be disengaged from the snap groove. As long as there is a movable gap 8 between the first limiting body 6 and the first push rod 2, these do not deviate from the principles of the present invention and therefore will fall within the scope of protection of the present invention.
[0052] For example, in another alternative embodiment, the first protrusion 21 can abut against the top inner wall of the N-shaped first limiting body 6, etc. As long as the first protrusion 21 abuts against the first limiting body 6, these do not deviate from the principles of the present invention and therefore will fall within the scope of protection of the present invention.
[0053] For example, in another alternative embodiment, the cross-sections of the first limiting body 6 and the second limiting body 7 can be rectangular, etc., as long as they can limit the first push rod 2 and the second push rod 3. These do not deviate from the principles of the present invention and therefore fall within the scope of protection of the present invention.
[0054] For example, in another alternative embodiment, the point where the push rocker 1 and the shell are pivotally connected may not be located in the middle of the push rocker 1, as long as the torque applied by the second push rod 3 on the second end 12 of the push rocker 1 is greater than the torque applied by the first push rod 2 on the first end 11 of the push rocker 1. These do not deviate from the principles of the present invention and therefore fall within the scope of protection of the present invention.
[0055] In addition, the present invention also provides a vehicle, which includes the switch for a vehicle described in any one of the above embodiments.
[0056] Thus far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art may make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will fall within the scope of protection of the present invention.
