Description

Technical Field

[0001] The invention belongs to the technical field of automobile parts and relates to a vehicle combination switch handle. Background Art

[0002] The vehicle combination switch refers to a multifunctional control device installed on the steering column of a car. The vehicle combination switch generally has two switch handles, left and right, which integrate multiple functions. In some models, the EPB (electronic parking brake) function is also integrated into the combination switch handle. This combination switch handle has an EPB switch, and the button at the end of the combination switch handle can trigger the contacts of the EPB switch by pressing. When the driver needs to use the parking brake function, he only needs to press the button at the end of the switch handle. The button triggers the contacts on the EPB switch, and the vehicle's electronic control unit will receive a signal and apply braking force to the wheels to keep the vehicle stationary.

[0003] At present, the outer contour of the EPB switch is designed to be a rectangular box-shaped structure, and the contacts are generally located on the front or side of the EPB switch. In order to ensure that the button at the end of the switch handle can accurately trigger the contacts of the EPB switch, the existing design usually requires the EPB switch to be placed vertically, that is, the length direction of the EPB switch is set along the width direction of the combination switch handle, so that the contacts of the EPB switch are aligned with the button.

[0004] Although the above layout ensures the effectiveness of the function, it also causes the EPB switch to occupy a larger installation space, forcing the overall outer diameter of the combination switch handle to increase, making it appear relatively thick. The thick outer diameter of the switch handle not only affects the overall aesthetics of the cockpit, but also reduces the overall coordination and compactness of the cockpit layout. Summary of the invention

[0005] The purpose of the present invention is to solve the above problems in the prior art and to provide a vehicle combination switch handle.

[0006] The purpose of the present invention can be achieved through the following technical solutions: A vehicle combination switch handle, comprising:

[0007] A handle housing, wherein a pressable button is disposed at an end of the handle housing, wherein the button is configured to be movable along the length direction of the end of the handle housing, wherein the button has a push rod portion, and wherein the push rod portion is provided with a driving inclined surface;

[0008] A micro switch, the micro switch is arranged in the handle housing, the micro switch is arranged horizontally and the length direction of the micro switch is consistent with the length direction of the handle housing, a pressable switch contact is protruded on the surface of the micro switch, and the switch contact is arranged to be movable in a direction perpendicular to the outer peripheral surface of the handle housing;

[0009] An elastic pressing piece, one end of which is connected to the micro switch and the other end of which is in contact with the switch contact, a part of the elastic pressing piece is bent to form an inclined portion, and the driving inclined surface is aligned with the inclined portion; when the button is pressed, the push rod part presses the inclined portion through the driving inclined surface to deform the elastic pressing piece and press the switch contact.

[0010] Preferably, the pressing direction of the button and the pressing direction of the switch contact are perpendicular to each other.

[0011] Preferably, the top surface of the switch contact is configured as a spherical structure, a curved structure, or an arc structure.

[0012] Preferably, one end of the elastic pressing piece that is in contact with the switch contact is set as a movable end, and the movable end is adjacent to the inclined portion; when the inclined portion is squeezed by the push rod portion, the inclined portion drives the movable end to be pressed downward in a direction close to the micro switch.

[0013] Preferably, the elastic pressing sheet has an elastic reset portion formed by bending, and the elastic reset portion is close to one end of the elastic pressing sheet connected to the micro switch; when the movable end is pressed downward in a direction close to the micro switch, the elastic reset portion deforms and accumulates force.

[0014] Preferably, the elastic pressing sheet is configured as a metal spring structure.

[0015] Preferably, it further includes a circuit board, wherein the circuit board is disposed in the handle housing, and the micro switch is electrically connected to the circuit board.

[0016] Preferably, a contact portion is provided on the circuit board, a conductive rubber is provided on the contact portion, the direction of the contact portion is consistent with the pressing direction of the button, and the button is provided with a pressing portion, and the pressing portion is aligned with the conductive rubber; when the button is pressed, the pressing portion squeezes the conductive rubber to trigger the contact portion.

[0017] Preferably, the circuit board includes a first plate body and a second plate body, the first plate body is arranged horizontally and the length direction of the first plate body is consistent with the length direction of the handle shell, the second plate body is arranged vertically and the thickness direction of the second plate body is consistent with the length direction of the handle shell, the micro switch is placed horizontally on the first plate body and the micro switch is electrically connected to the first plate body, and the contact portion is located on the second plate body.

[0018] Preferably, a mounting bracket is fixedly disposed in the handle housing, and the button is slidably connected to the mounting bracket.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The EPB switch adopts a flat and compact layout to effectively reduce the outer diameter of the switch handle. The contact is indirectly pressed by the driving bevel and elastic pressure piece to meet the control requirements, and the beauty, coordination and compactness of the cockpit are improved.

[0021] 2. Since the elastic pressing piece presses the switch contact by deforming and pressing downward, the pressing angle of the elastic pressing piece during the pressing process is not necessarily completely radial, and the spherical, curved or arc surface structure can better adapt to pressing in different directions. Even if the pressing angle of the elastic pressing piece deviates slightly from the radial direction (the direction perpendicular to the outer circumference of the handle shell), it can ensure that the switch contact is pressed.

[0022] 3. When the movable end is pressed down in the direction close to the micro switch, the elastic reset part will deform and accumulate force. This deformation is an elastic deformation. When the external force is removed, the elastic reset part will return to its original shape.

[0023] 4. The button can trigger two sets of signals by pressing it once. One set of signals is generated by the push rod and the elastic pressure piece triggering the switch contacts on the micro switch, and the other set of signals is generated by the pressing part triggering the contact part through the conductive rubber. The two sets of signals are generated by different mechanical pressing mechanisms. This design not only improves the diversity and reliability of functions, but also optimizes the user's operating experience, reduces the number of components, and further reduces the outer diameter of the combination switch handle.

[0024] 5. The first plate is arranged horizontally, and its length direction is consistent with the length direction of the handle shell, which reduces the radial space occupied by the handle shell. The second plate is arranged vertically, and its thickness direction is consistent with the length direction of the handle shell, which makes full use of the longitudinal space inside the handle shell. Through this layered design, the space inside the handle is efficiently utilized, so that the outer diameter of the handle can be further reduced, making the handle more slender and beautiful.

DETAILED DESCRIPTION

[0032] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0033] like Figures 1 to 6 As shown, a vehicle combination switch handle comprises: a handle housing 100, a pressable button 200 is arranged at the end of the handle housing 100, and the button 200 is arranged to be movable along the length direction of the end of the handle housing 100, and the button 200 has a push rod portion 210, and the push rod portion 210 is provided with a driving inclined surface 211; a micro switch 300, the micro switch 300 is arranged in the handle housing 100, the micro switch 300 is arranged horizontally, and the length direction of the micro switch 300 is consistent with the length direction of the handle housing 100, and the surface convex of the micro switch 300 is There is a pressable switch contact 310, which is configured to be movable in a direction perpendicular to the outer circumference of the handle housing 100; an elastic pressing piece 400, one end of which is connected to the micro switch 300 and the other end is in contact with the switch contact 310, a part of the elastic pressing piece 400 is bent to form an inclined portion 410, and the driving inclined surface 211 is aligned with the inclined portion 410; when the button 200 is pressed, the push rod portion 210 squeezes the inclined portion 410 through the driving inclined surface 211 to deform the elastic pressing piece 400 and press the switch contact 310.

[0034] It should be noted that the conventional switch is designed to be arranged vertically so that the contacts on the switch are aligned with the button 200. However, this conventional design causes the length direction of the switch to be along the radial direction (width direction) of the combination switch handle, which results in an increase in the radial dimension of the switch handle because the length direction of the switch occupies more radial space.

[0035] The handle housing 100 is the outer shell of the entire switch handle, and the outer end of the button 200 protrudes from the end of the handle housing 100. The micro switch 300 is preferably an EPB switch. The micro switch 300 is similar to a rectangular box-shaped structure. In this embodiment, by placing the micro switch 300 horizontally, its length direction is consistent with the length direction of the handle housing 100, and the space occupied by the micro switch 300 in the width direction (i.e., radial direction) is greatly reduced, thereby reducing the radial size of the handle housing 100. The micro switch 300 is placed horizontally to reduce the overall outer diameter of the switch handle, which not only makes the handle look more slender, but also improves the space utilization in the cockpit, making the cockpit layout more compact and coordinated.

[0036] There is a protruding pressable switch contact 310 on the surface of the micro switch 300, and the switch contact 310 can move in a direction perpendicular to the outer peripheral surface of the handle housing 100. Such a design is actually formed after the micro switch 300 is laid flat, which also causes the button 200 to be unable to directly push or trigger the switch contact 310. Based on the above reasons, in this embodiment, a push rod portion 210 is provided at the inner end of the button 200, and the end surface of the push rod portion 210 is provided as a driving inclined surface 211. A partial area of ​​the elastic pressing sheet 400 is formed by bending to form an inclined surface 410. The function of the driving inclined surface 211 is to cooperate with the inclined surface 410 to change the direction of the pressing force, so as to effectively transfer the pressing force of the button 200 to the switch contact 310, and ensure that the switch contact 310 is correctly triggered.

[0037] Since the pressing direction of the button 200 is offset from the moving direction of the switch contact 310, it means that the button 200 cannot directly push the switch contact 310, and the switch contact 310 must be pressed through the driving inclined surface 211 and the elastic pressing piece 400. Specifically, when the button 200 is pressed, the push rod portion 210 squeezes the elastic pressing piece 400. Since the driving inclined surface 211 and the inclined surface portion 410 are connected by the inclined surface matching, the axial pressing force (along the length direction of the handle housing 100) applied by the button 200 is converted into a radial pressing force (perpendicular to the outer peripheral surface of the handle housing 100) by the driving inclined surface 211 and the inclined surface portion 410. Under the action of the radial pressing force, the elastic pressing piece 400 is deformed and pressed downward, so that the elastic pressing piece 400 presses the switch contact 310, so that the button 200 can indirectly press the switch contact 310.

[0038] On the basis of the above-mentioned embodiment, the pressing direction of the button 200 is perpendicular to the pressing direction of the switch contact 310. By designing the pressing direction of the button 200 to be perpendicular to the pressing direction of the switch contact 310, the micro switch 300 can be placed flat. In this way, the length direction of the micro switch 300 is consistent with the length direction of the handle housing 100, rather than the radial direction. This greatly reduces the radial dimension of the handle housing 100, making the overall design more compact. Through the cooperation of the driving inclined surface 211 and the inclined surface portion 410, the pressing force of the button 200 can be effectively transmitted to the switch contact 310, even if the pressing direction of the button 200 is perpendicular to the pressing direction of the switch contact 310. This design ensures the accurate triggering of the switch contact 310 and improves the reliability of the operation.

[0039] On the basis of the above-mentioned embodiment, the top surface of the switch contact 310 is set to a spherical structure, a curved structure or an arc structure.

[0040] The spherical, curved or arcuate structure provides a smooth transition surface, making the operation smoother; specifically, since the elastic pressing piece 400 presses the switch contact 310 by deforming and pressing downward, the pressing angle of the elastic pressing piece 400 during the pressing process is not necessarily completely radial, and the spherical, curved or arcuate structure can better adapt to pressing in different directions. Even if the pressing angle of the elastic pressing piece 400 deviates slightly from the radial direction (the direction perpendicular to the outer circumferential surface of the handle shell 100), it can ensure that the switch contact 310 is pressed.

[0041] Based on the above embodiment, one end of the elastic pressing piece 400 that is in contact with the switch contact 310 is set as a movable end 420, and the movable end 420 is adjacent to the inclined portion 410; when the inclined portion 410 is squeezed by the push rod portion 210, the inclined portion 410 drives the movable end 420 to be pressed downward in a direction close to the micro switch 300.

[0042] Since the movable end 420 and the inclined surface 410 are adjacent, this means that when the push rod portion 210 squeezes the inclined surface 410 and causes the inclined surface 410 to be pressed downward, the movable end 420 can be pushed downward together, thereby squeezing the switch contact 310, thereby achieving a clever mechanical linkage.

[0043] Based on the above embodiment, the elastic pressing piece 400 has an elastic reset portion 430 formed by bending, and the elastic reset portion 430 is close to one end of the elastic pressing piece 400 connected to the micro switch 300; when the movable end 420 is pressed downward in a direction close to the micro switch 300, the elastic reset portion 430 deforms and accumulates force.

[0044] The purpose of providing the elastic reset portion 430 is to allow the elastic pressing piece 400 to be pressed down and deformed, and at the same time to allow the elastic pressing piece 400 to bounce back and reset to ensure the next trigger. Specifically, when the movable end 420 is pressed down in the direction close to the micro switch 300, the elastic reset portion 430 will deform and accumulate force. This deformation is an elastic deformation, and when the external force is removed, the elastic reset portion 430 will return to its original shape.

[0045] On the basis of the above-mentioned implementation, the elastic pressing sheet 400 is configured as a metal spring sheet structure.

[0046] like Figures 1 to 4 As shown, based on the above embodiment, it also includes a circuit board, which is arranged in the handle housing 100, and the micro switch 300 is electrically connected to the circuit board. The circuit board plays a key role in the vehicle combination switch handle, and is responsible for processing and transmitting the electrical signal after the switch contact 310 is triggered.

[0047] On the basis of the above embodiment, a contact portion 610 is provided on the circuit board, a conductive rubber 620 is provided on the contact portion 610, the direction of the contact portion 610 is consistent with the pressing direction of the button 200, the button 200 is provided with a pressing portion 220, and the pressing portion 220 is aligned with the conductive rubber 620; when the button 200 is pressed, the pressing portion 220 squeezes the conductive rubber 620 to trigger the contact portion 610.

[0048] In this embodiment, the button 200 can trigger two groups of signals by pressing once, one group of signals is generated by the push rod portion 210 and the elastic pressing piece 400 triggering the switch contact 310 on the micro switch 300, and the other group of signals is generated by the pressing portion 220 triggering the contact portion 610 through the conductive rubber 620. The two groups of signals are generated by different mechanical pressing mechanisms. This design not only improves the diversity and reliability of functions, but also optimizes the user's operating experience, reduces the number of components, and further reduces the outer diameter of the combination switch handle.

[0049] Specifically, the micro switch 300 is directly connected to the EPB system, and the circuit inside the micro switch 300 is opened and closed to generate a first set of electrical signals, which directly control the start or release of the EPB system. The pressing part 220 squeezes the conductive rubber 620, triggering the contact part 610 to generate a second set of electrical signals, which trigger other supporting functions, such as lighting or extinguishing the EPB status indicator light or issuing a sound prompt or displaying the EPB status information on the vehicle dashboard or other auxiliary functions.

[0050] In this embodiment, the circuit board includes a first plate body 500 and a second plate body 600. The first plate body 500 is arranged horizontally and the length direction of the first plate body 500 is consistent with the length direction of the handle housing 100. The second plate body 600 is arranged vertically and the thickness direction of the second plate body 600 is consistent with the length direction of the handle housing 100. The micro switch 300 is placed horizontally on the first plate body 500 and the micro switch 300 is electrically connected to the first plate body 500. The contact portion 610 is located on the second plate body 600.

[0051] By dividing the circuit board into a first plate body 500 and a second plate body 600, and placing the first plate body 500 horizontally and placing the second plate body 600 vertically, efficient use of space and reasonable allocation of functions are achieved. The first plate body 500 is placed horizontally, and its length direction is consistent with the length direction of the handle housing 100, which reduces the radial space occupied by the handle housing 100. The second plate body 600 is placed vertically, and its thickness direction is consistent with the length direction of the handle housing 100, which fully utilizes the longitudinal space inside the handle housing 100. Through this layered design, the space inside the handle is efficiently utilized, so that the outer diameter of the handle can be further reduced, making the handle more slender and beautiful.

[0052] like Figure 1 , Figure 3 , Figure 5 As shown, on the basis of the above embodiment, a mounting bracket 110 is fixedly provided in the handle housing 100 , and the button 200 is slidably connected to the mounting bracket 110 .

[0053] The mounting bracket 110 is fixed in the handle housing 100 to provide a stable support point for the button 200 and other components. The button 200 and the mounting bracket 110 are connected by sliding to ensure that the button 200 can move smoothly along the length direction of the handle housing 100.

[0054] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0055] In addition, in the present invention, descriptions such as "first", "second", "one", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0056] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0057] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
