Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of automobile parts, and relates to a combined switch handle for vehicle. BACKGROUND

[0002] The vehicle combined switch is a multifunctional control device installed on the steering wheel column of a vehicle. The vehicle combined switch generally has left and right two switch handles, and multiple functions are integrated on the two switch handles. In some vehicle models, the EPB (electronic parking brake) function is also integrated on the combined switch handle. The combined switch handle has an EPB switch therein, and the button at the end of the combined switch handle can trigger the contact of the EPB switch by pressing. When the driver needs to use the parking brake function, the button at the end of the switch handle is only needed to be pressed to trigger the contact of the EPB switch, and the electronic control unit of the vehicle will receive the signal and apply the braking force to the wheels to keep the vehicle stationary.

[0003] At present, the EPB switch is designed as a cuboid box structure in shape, and the contact is generally located on the front or side surface of the EPB switch. In order to ensure that the button at the end of the switch handle can accurately trigger the contact of the EPB switch, the existing design usually requires that the EPB switch is placed vertically, that is, the length direction of the EPB switch is arranged along the width direction of the combined switch handle, so that the contact of the EPB switch is aligned with the button.

[0004] Although the above layout ensures the effectiveness of the function, it also causes the EPB switch to occupy a large installation space, forcing the overall profile diameter of the combined switch handle to increase, which appears relatively thick. The relatively thick switch handle not only affects the overall aesthetic appearance in the driver's cabin, but also reduces the overall coordination and compactness of the layout in the driver's cabin.

[0020] 1, EPB switch adopts the compact layout of lying down to effectively reduce the outline diameter of switch handle, meets the operation demand through the indirect pressing contact of driving slope and elastic pressing piece, and improves the beauty, coordination and compactness of cockpit.

[0021] 2, since the elastic pressing piece is pressed switch contact through deformation and down pressure, the pressing angle of elastic pressing piece in the down pressure process is not necessarily completely radial, and the spherical surface, curved surface or arc surface structure can better adapt to the pressing in different directions, even if the pressing angle of elastic pressing piece is slightly deviated from the radial direction (the direction perpendicular to the outer circumferential surface of handle shell), the switch contact can be ensured to be pressed down.

[0022] 3, when the movable end is pressed down in the direction close to the micro switch, the elastic reset part will be deformed and store force.The deformation is a kind of elastic deformation, and when the external force is removed, the elastic reset part will restore to the original shape.

Detailed Implementation

[0032] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0033] like Figures 1 to 6 As shown, a vehicle combination switch handle includes: a handle housing 100, with a pressable button 200 at one end of the handle housing 100. The button 200 is configured to move along the length direction of the end of the handle housing 100, and the button 200 has a push rod portion 210 with a driving inclined surface 211; and a micro switch 300 disposed inside the handle housing 100, the micro switch 300 being horizontally positioned and its length direction being aligned with the length direction of the handle housing 100, and the surface of the micro switch 300 being convex. The device includes a pressable switch contact 310, which is configured to move in a direction perpendicular to the outer peripheral surface of the handle housing 100; an elastic pressure plate 400, one end of which is connected to the micro switch 300 and the other end of which is in contact with the switch contact 310; a portion of the elastic pressure plate 400 is bent to form a beveled portion 410, and a drive bevel 211 is aligned with the beveled portion 410; when the button 200 is pressed, the push rod portion 210 compresses the beveled portion 410 through the drive bevel 211 to deform the elastic pressure plate 400 and press the switch contact 310.

[0034] It should be noted that traditional switches use a vertically arranged design to align the contacts on the switch with button 200. However, this traditional design causes the length of the switch to run along the radial direction (width direction) of the switch handle. This results in an increase in the radial dimension of the switch handle because the length of the switch occupies more radial space.

[0035] The handle shell 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 shell 100. The micro switch 300 is preferably an EPB switch, and the micro switch 300 is similar to a rectangular box-shaped structure. In the present embodiment, 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 shell 100. The space occupied by the width direction (i.e., the radial direction) of the micro switch 300 is greatly reduced, thereby reducing the radial dimension of the handle shell 100. The horizontal arrangement of the micro switch 300 reduces the overall profile of the switch handle, making the handle look more slender, and improving the space utilization in the cockpit, making the cockpit layout more compact and coordinated.

[0036] The surface of the micro switch 300 has a protruding switch contact 310 that can be pressed in a direction perpendicular to the outer surface of the handle shell 100. Such a design is actually due to the horizontal arrangement of the micro switch 300, which also results in the button 200 being unable to directly push or trigger the switch contact 310. Based on the above reasons, the inner end of the button 200 is provided with a push rod portion 210, and the end surface of the push rod portion 210 is provided with a driving slope 211. A portion of the elastic pressing sheet 400 is bent to form a slope portion 410. The driving slope 211 is configured to cooperate with the slope portion 410 to change the direction of the pressing force, so as to effectively transmit the pressing force of the button 200 to the switch contact 310, and ensure that the switch contact 310 is triggered correctly.

[0037] Since the pressing direction of the button 200 is offset from the movement 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 slope 211 and the elastic pressing sheet 400. Specifically, when the button 200 is pressed, the push rod portion 210 presses the elastic pressing sheet 400. Since the driving slope 211 and the slope portion 410 are connected by a slope cooperation, the axial pressing force (in the length direction of the handle shell 100) applied by the button 200 is converted by the driving slope 211 and the slope portion 410 into a radial pressing force (perpendicular to the outer surface of the handle shell 100). Under the action of the radial pressing force, the elastic pressing sheet 400 is deformed and pressed down, so that the elastic pressing sheet 400 presses the switch contact 310, thereby enabling the button 200 to indirectly press the switch contact 310.

[0038] On the basis of the above-mentioned embodiments, 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 horizontally. In this way, the length direction of the micro switch 300 is consistent with the length direction of the handle shell 100, rather than the radial direction. This greatly reduces the radial size of the handle shell 100, making the overall design more compact. Through the cooperation of the driving slope 211 and the slope part 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 embodiments, the top surface of the switch contact 310 is provided with a spherical surface structure or a curved surface structure or an arc surface structure.

[0040] The spherical surface, curved surface or arc surface structure provides a smooth transition surface, making the operation more smooth. Specifically, since the elastic pressing piece 400 is pressed against the switch contact 310 by deforming and pressing down, the pressing angle of the elastic pressing piece 400 during the pressing down process is not necessarily completely radial, and the spherical surface, curved surface or arc surface 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 still ensure that the switch contact 310 is pressed down.

[0041] On the basis of the above-mentioned embodiments, the end of the elastic pressing piece 400 that is in contact with the switch contact 310 is provided with a movable end 420, and the movable end 420 is adjacent to the slope part 410; when the slope part 410 is extruded by the push rod part 210, the slope part 410 drives the movable end 420 to press down towards the micro switch 300.

[0042] Since the movable end 420 is adjacent to the slope part 410, this means that when the slope part 410 is pressed down by the push rod part 210, it can drive the movable end 420 to press down together, and then extrude the switch contact 310, thereby realizing a clever mechanical linkage.

[0043] On the basis of the above-mentioned embodiments, the elastic pressing piece 400 has an elastic reset part 430 formed by bending, and the elastic reset part 430 is close to the end of the elastic pressing piece 400 connected to the micro switch 300; when the movable end 420 presses down towards the micro switch 300, the elastic reset part 430 deforms and stores energy.

[0044] The purpose of providing the elastic reset part 430 is to allow the elastic pressure plate 400 to be pressed down and deformed, while simultaneously allowing the elastic pressure plate 400 to spring back and reset, ensuring the next triggering. Specifically, when the movable end 420 is pressed down towards the micro switch 300, the elastic reset part 430 deforms and stores force. This deformation is an elastic deformation, and when the external force is removed, the elastic reset part 430 returns to its original shape.

[0045] Based on the above implementation method, the elastic pressure plate 400 is configured as a metal spring plate structure.

[0046] like Figures 1 to 4 As shown, based on the above embodiment, a circuit board is also included. The circuit board is disposed inside 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 automotive combination switch handle, responsible for processing and transmitting the electrical signal after the switch contact 310 is triggered.

[0047] Based on the above embodiment, a contact portion 610 is provided on the circuit board, and a conductive rubber 620 is provided on the contact portion 610. The orientation 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, which 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, button 200 can trigger two sets of signals with a single press. One set of signals is generated by the push rod 210 and the elastic pressure plate 400 triggering the switch contact 310 on the micro switch 300, while the other set of signals is generated by the pressing part 220 triggering the contact part 610 through the conductive rubber 620. The two sets of signals are generated by different mechanical pressing mechanisms. This design not only improves the versatility and reliability of the functions but also optimizes the user experience, reduces the number of components, and further reduces the outer diameter of the combination switch handle.

[0049] Specifically, the microswitch 300 is directly connected to the EPB system. The opening and closing of the internal circuit of the microswitch 300 generates 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. The second set of electrical signals triggers other supporting functions, such as lighting or turning off the EPB status indicator light, emitting an audible prompt, displaying EPB status information on the vehicle's instrument panel, or other auxiliary functions.

[0050] In the embodiment, the circuit board comprises 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 shell 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 shell 100, the micro switch 300 is arranged horizontally on the first plate body 500 and the micro switch 300 is electrically connected with the first plate body 500, and the contact point part 610 is located on the second plate body 600.

[0051] By dividing the circuit board into the first plate body 500 and the second plate body 600, arranging the first plate body 500 horizontally and arranging the second plate body 600 vertically, efficient use of space and reasonable allocation of functions are realized. 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 shell 100, thereby reducing the radial space occupation of the handle shell 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 shell 100, thereby fully utilizing the longitudinal space inside the handle shell 100. Through this layered design, the space inside the handle is used efficiently, so that the profile diameter of the handle can be further reduced, and the handle is more slender and beautiful.

[0052] As shown in Figure 1 , Figure 3 , Figure 5 , on the basis of the above embodiment, the handle shell 100 is fixedly provided with a mounting bracket 110, and the button 200 is in sliding connection with the mounting bracket 110.

[0053] The mounting bracket 110 is fixed in the handle shell 100, and provides a stable support point for the button 200 and other components. The button 200 is in sliding connection with the mounting bracket 110, so as to ensure that the button 200 can move smoothly along the length direction of the handle shell 100.
