[0002] This application generally relates to the field of vehicles, and more particularly to a switch device, a handle device, and a vehicle. Background Technology

[0003] In some vehicles, a push-button switch for generating a vehicle unlock signal is located in the handlebar assembly. The main function of the push-button switch is to activate its built-in switch (such as a tactile switch) by pressing the button, thereby generating an unlock signal. Upon receiving the unlock signal, the vehicle control unit controls the physical locking lever to move and unlock the vehicle. Summary of the Invention

[0004] Through long-term observation and research, the inventors of this application discovered that in existing technologies, the button switch needs to be pressed all the way down to trigger the built-in switch to generate an unlock signal. Only after receiving the unlock signal can the vehicle control device control the locking lever to move and perform the unlocking operation. However, because the locking lever takes a certain amount of time to move, the locking lever has not yet completed the unlocking operation when the button pressing action ends. Therefore, users need to wait for a period of time after pressing the button before they can open the car door, resulting in a poor user experience.

[0005] To at least partially solve the above-mentioned technical problems, according to a first aspect of this application, a switching device is provided, including a housing, a switch, a button, and an intermediate element. The housing has an opening. The switch includes a pressable portion and is housed within the housing, the switch switching between an off state and an on state in response to a pressing force applied to the pressable portion. The button is coupled to the housing at the opening and is movable toward the switch by a pressing operation. The intermediate element is at least partially deformable, drivenly connected to the button, and operatively engaged with the pressable portion of the switch. The intermediate element is configured such that when the button is pressed and moved toward the switch, the intermediate element is driven by the button to press the pressable portion of the switch, thereby switching the switch to the on state, and after the switch is switched to the on state, the intermediate element allows the button to continue moving toward the switch a certain distance.

[0006] According to a first aspect of this application, the intermediate element includes: a transmission portion drivenly connected to the button; a pressing portion operatively engaged with a pressed portion of the switch; a holding portion holding the intermediate element within the housing; a first deformable connecting portion connecting the transmission portion to the pressing portion; and a second deformable connecting portion connecting the holding portion to one of the transmission portion, the pressing portion, and the first deformable connecting portion, and holding the pressing portion in an initial position where the pressed portion of the switch is not pressed.

[0007] According to a first aspect of this application, during the application of a pressing operation, the button has a first travel and a second travel; wherein, in the first travel, the button drives the transmission part and the pressing part together to move toward the switch, so as to press the pressed part of the switch by the pressing part; and wherein, in the second travel, the button continues to drive the transmission part to move toward the switch, and the pressing part remains pressing the pressed part of the switch.

[0008] According to a first aspect of this application, the first deformable connecting portion and the second deformable connecting portion extend obliquely relative to the direction of movement of the transmission portion.

[0009] According to a first aspect of this application, the transmission part is cylindrical and includes a cavity, wherein, during the second stroke, the pressing part is gradually received in the cavity.

[0010] According to a first aspect of this application, the retaining part is a base, which is supported by the bottom of the housing.

[0011] According to a first aspect of this application, the transmission part, the pressing part, the first deformable connecting part and the second deformable connecting part together form a set of sub-elements, the intermediate element includes two sets of the sub-elements, and both sets of sub-elements are held in the housing by the holding part.

[0012] According to a first aspect of this application, the intermediate element is integrally formed of an elastic material.

[0013] According to a first aspect of this application, the switching device further includes a push rod disposed between the button and the transmission part of the intermediate element, with its opposite ends abutting against the button and the transmission part of the intermediate element respectively, so as to transmit pressing force from the button to the transmission part of the intermediate element.

[0014] According to a first aspect of this application, the button is rotatably connected to the housing so as to rotate toward the switch when a pressing operation is applied.

[0015] According to a first aspect of this application, the switching device further includes a return spring arranged to bias the button toward its initial position.

[0016] According to a first aspect of this application, the switching device further includes: an inner cover disposed within the housing and covering a portion of the intermediate element, the switch, and the push rod, wherein the inner cover has a guide hole through which the push rod extends out of the inner cover, and the button and the return spring are disposed outside the inner cover.

[0017] According to a second aspect of this application, a handle device is provided for a vehicle door, the handle device having the aforementioned switch device configured to generate an unlock signal indicating that the vehicle door should be unlocked when the button is pressed.

[0018] According to a second aspect of this application, a handle device includes: a handle seat, the handle seat including a handle cavity; wherein the switching device is arranged in the handle seat such that a button is located in the handle cavity, such that a pressing operation applied to the button occurs in the handle cavity.

[0019] According to a third aspect of this application, a vehicle is provided, characterized by including the aforementioned handle device.

[0020] The switching device of this application provides a button with a longer pressing stroke by incorporating an intermediate element, at least partially deformable, between the button and the pressed portion of the switch to transmit the pressing force. During button pressing, the switch is activated before the button is fully depressed, generating an unlocking signal. After the switch is activated, the intermediate element can deform to allow the button to continue moving a distance toward the switch; the time required for this process is the same as the time required for the lock lever to physically unlock. This compensates for the lag time in the lock lever unlocking operation, synchronizing the pressing completion time with the lock lever unlocking completion time. This allows users to open the car door without waiting for the lock lever to unlock after pressing the switch, resulting in a better user experience. Attached Figure Description

Detailed Implementation

[0023] Various specific embodiments of this application will now be described with reference to the accompanying drawings, which form part of this specification. It should be understood that although directional terms such as "front," "rear," "upper," "lower," "left," "right," "top," and "bottom" are used in this application to describe various exemplary structural parts and elements, their use is merely for illustrative purposes and is based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in this application can be arranged in different orientations, these directional terms are for illustrative purposes only and should not be considered as limiting.

[0024] Figure 1A-1C The specific structure of the switching device 100 according to the first embodiment of this application is shown, wherein, Figure 1A This is a perspective view of the switching device 100. Figure 1B This is an exploded view of the switching device 100; Figure 1C yes Figure 1A The switch device shown is a cross-sectional view along line AA.

[0025] like Figure 1A As shown, the switch device 100 has a housing 106 with an opening 107. The switch device 100 also includes a button cover 102 covering the opening 107 of the housing 106, and components housed within the housing 106. The button cover 102 is formed of a rubber layer.

[0026] like Figure 1B and 1CAs shown, housing 106 includes an upper housing 106a and a lower housing 106b, with opening 107 defined by the upper housing 106a. Switching device 100 also includes a button 104, an inner cover 108, an intermediate element 110, a push rod 111, a switch 112, and a return spring 117, all housed within housing 106. Button 104 is connected to housing 106 at opening 107 and can be pressed to move toward switch 112. A button cover 102 covers the outside of button 104; pressing the button cover 102 provides a softer tactile feedback. In the illustrated embodiment, button 104 is rotatably connected to opening 107 of upper housing 106a via pivot 132 to rotate toward switch 112 when pressed. Those skilled in the art should also understand that in other embodiments, button 104 may also be slidably mounted to the opening 107 of the upper housing 106a.

[0027] Continue as Figure 1B and 1C As shown, an inner cover 108 is disposed within a housing 106 and covers an intermediate element 110, a switch 112, and a portion of a push rod 111. The inner cover 108 has a guide hole 135 through which the push rod 111 extends out of the inner cover 108. A button 104 and a return spring 117 are disposed outside the inner cover 108. The intermediate element 110 is at least partially deformable, operatively connected to the button 104, and operably engaged with the pressed portion 113 of the switch 112.

[0028] Continue as Figure 1B and 1C As shown, switch 112 includes a pressable portion 113 and a circuit board 109, with a trigger portion 141 on the circuit board 109. When no pressure is applied to the pressable portion 113, it separates from the trigger portion 141 on the circuit board 109, and switch 112 is in the off state. When a certain pressure is applied to the pressable portion 113, it undergoes elastic deformation, thereby contacting the trigger portion 141 on the circuit board 109, and switch 112 is in the on state. When switch 112 is on, it generates an unlocking signal and transmits it to the vehicle control device for unlocking. Therefore, switch 112 can switch between the off state and the on state in response to the pressure applied to the pressable portion 113. In the illustrated embodiment, the pressable portion 113 is an elastic metal sheet, such as a metal dome switch. Those skilled in the art should also understand that in other embodiments, the pressable portion 113 may be other components that can undergo elastic deformation under pressure.

[0029] When button 104 is pressed and moves toward switch 112, intermediate element 110 is driven by button 104 to press the pressed portion 113 of switch 112, thereby switching switch 112 to the ON state. After switch 112 is switched to the ON state, intermediate element 110 allows button 104 to continue moving toward switch 112 a certain distance. Thus, even after switch 112 generates an unlock signal, the operator can still press button 104.

[0030] In the illustrated embodiment, the two ends of the push rod 111 are operatively engaged with the button 104 and the intermediate element 110, respectively. The button 104 transmits pressing force to the intermediate element 110 via the push rod 111, and the intermediate element 110 then transmits the pressing force to the pressed portion 113 of the switch 112. In other embodiments, the push rod 111 may be omitted, and instead, a protrusion may be provided on the inner side of the button 104 to push the intermediate element 110, especially when the button 104 is designed to be translational rather than rotatable.

[0031] In the illustrated embodiment, there are two push rods 111, namely push rod 111a and push rod 111b. There are two guide holes 135, namely guide hole 135a and guide hole 135b. There are two return springs 117, namely return spring 117a and return spring 117b. There are two pressed parts 113, namely pressed part 113a and pressed part 113b. There are two triggered parts 141, namely triggered part 141a and triggered part 141b. The above components or features are arranged symmetrically with respect to the center line of the switching device 100.

[0032] Figure 2 This is a schematic diagram showing the concealed components of the switching device 100. Figure 2 The button cover 102, upper housing 106a and inner cover 108 of the switch device 100 are concealed to more clearly show the mating relationship of the components in the housing cavity.

[0033] like Figure 2 As shown, in the switch device 100, a return spring 117 is disposed between the button 104 and the lower housing 106b. When the button 104 is pressed, the button 104 rotates and compresses the return spring 117. The return spring 117 provides a biasing force to the button 104 in the opposite direction, biasing the button 104 toward its initial position (unpressed position). A push rod 111 is disposed between the button 104 and the intermediate element 110, with its opposite ends abutting against the button 104 and the intermediate element 110 respectively, to transmit the pressing force from the button 104 to the intermediate element 110. The intermediate element 110 rests on the bottom of the lower housing 106b.

[0034] Figures 3A-3EThe specific structure and different states of the intermediate element 110 are shown. Figure 3A This is a 3D view of intermediate component 100. Figure 3B This is a side view of intermediate element 100. Figure 3C-3E It is the intermediate element 100 along Figure 3B The BB line cross-sectional view shows the intermediate element in the undeformed state, the intermediate deformed state, and the final deformed state.

[0035] In the illustrated embodiment, the intermediate element 110 is integrally formed of an elastic material (e.g., rubber), thereby enabling elastic deformation when subjected to pressure. The intermediate element 110 has a structure symmetrically arranged with respect to its centerline.

[0036] like Figures 3A-3B As shown, the intermediate element 110 includes a holding portion 301, a transmission portion 302 (302a, 302b), a pressing portion 312 (312a, 312b), a first deformable connecting portion 322 (322a, 322b), and a second deformable connecting portion 324 (324a, 324b). The transmission portion 302 is driven to the button. The transmission portion 302a, the pressing portion 312a, the first deformable connecting portion 322a, and the second deformable connecting portion 324a together form a first set of sub-elements, and the transmission portion 302b, the pressing portion 312b, the first deformable connecting portion 322b, and the second deformable connecting portion 324b together form a second set of sub-elements. Both sets of sub-elements are held in the housing 106 by the holding portion 301. In the illustrated embodiment, the holding portion 301 is a base, which is generally plate-shaped with a certain thickness and is supported by the bottom of the housing 106.

[0037] Continue as Figures 3A-3BAs shown, the transmission part 302 is cylindrical and includes cavities 332 (332a, 332b) for receiving the pressing part 312. The push rod described above is disposed between the button and the transmission part 302 of the intermediate element 110, with one end abutting against the top of the transmission part 302 to transmit pressing force from the button to the transmission part 302. A first deformable connecting part 322 connects the transmission part 302 to the pressing part 312. A second deformable connecting part 324 connects the holding part 301 to the transmission part 302 and holds the pressing part 312 in the initial position of the pressed part when the switch is not pressed. The pressing part 312 operatively engages with the pressed part of the switch and is generally cylindrical. The first deformable connecting part 322 and the second deformable connecting part 324 extend obliquely relative to the direction of movement of the transmission part 302. Therefore, in cross-section, the first deformable connecting part 322 and the second deformable connecting part 324 together form a corrugated shape. Those skilled in the art will understand that in other embodiments, the second deformable connecting portion 324 may also connect the retaining portion 301 to the pressing portion 312 or the first deformable connecting portion 322, as long as the transmission portion 302 and the pressing portion 312 are allowed to move relative to the retaining portion 301.

[0038] During the pressing operation, the button has a first travel and a second travel. In the first travel, the button drives the transmission part 302 and the pressing part 312 together to move toward the switch, so as to press the pressed part of the switch by the pressing part 312. In the second travel, the button continues to drive the transmission part 302 toward the switch, and the pressing part 312 stops moving due to being blocked by the pressed part of the switch. Therefore, the pressing part 312 is gradually received in the cavity 332. During this process, the pressing part 312 holds the pressed part of the switch.

[0039] like Figure 3C-3E As shown, during the first segment of the button's travel, when the transmission part 302 is subjected to pressing force F, the second connecting part 324 first undergoes elastic deformation, causing the transmission part 302 to move downwards, and can move downwards together with the pressing part 312 via the first deformable connecting part 322. During its downward movement, the pressing part 312 applies pressure to the pressed part of the switch, causing the pressed part to undergo elastic deformation and switch the switch to the ON state. During the second segment of the travel, the pressing part 312 is blocked by the pressed part 113 and cannot continue to move downwards (see...). Figure 3D Under the action of the pressing force F, the transmission part 302 can continue to move downward, thereby displacing the transmission part 302 downward relative to the pressed part 113. The first deformable connecting part 322 deforms under the movement of the transmission part 302, and the cylindrical cavity 332 of the transmission part 302 is fitted downward onto the outside of the pressing part 312, so that the pressing part 312 is gradually received in the cavity 332. The transmission part 302 stops moving downward until it is blocked by the switch.

[0040] Those skilled in the art will understand that, although in the illustrated embodiment the intermediate element 110 is integrally formed of an elastic material (e.g., rubber), in other embodiments the intermediate element 110 may also be made of an elastic material (e.g., rubber) only at the first deformable connection portion 322 and the second deformable connection portion 324.

[0041] Figures 4A-4C The operation of the switching device 100 is shown along the path. Figure 1B A cross-sectional view of the CC line in the diagram, where... Figure 4A In the middle, the switch device 100 is in the unpressed state, Figure 4B In the middle, the switch device 100 is in the pressed middle state. Figure 4C In the middle, the switch device 100 is in the pressed-complete state. To more clearly illustrate the cooperation relationship between the various components of the switch device, Figures 4A-4C The upper housing 106a and button cover 102 are omitted.

[0042] like Figures 4A-4B As shown, during the first segment of the travel of button 104, when the user applies a pressing force F to the switch device 100, button 104 rotates downward. This rotation transmits the pressing force to push rod 111. Push rod 111 passes through inner cover 108 and transmits the pressing force to the transmission part 302 of intermediate element 110, causing it to move downward. The downward movement of transmission part 302 drives pressing part 312 downward, thereby applying pressure to the pressed part 113 of switch 112 to make it contact the unlock trigger section on circuit board 109, thus turning on the switch and generating an unlock signal. In the embodiment of this application, to turn on switch 112, corresponding to the first segment of the travel of button 104, transmission part 302 moves downward by 0.3 mm (see...). Figure 4B (The state shown).

[0043] like Figure 4B-4C As shown, during the second stroke of button 104, push rod 111 can continue to push transmission part 302 downward by 1.2mm (see...). Figure 4C (As shown in the diagram), the pressing part 312 maintains its pressing state on the pressed part 113, thus keeping the switch in the ON state. Because the return spring 117 provides a reverse biasing force to the button 104, the button 104 tends to move towards its initial position. Therefore, when the user no longer applies the pressing force F, the button 104 will return to its initial position under the action of the biasing force (as shown in the diagram). Figure 4A (As shown).

[0044] When applying a pressing operation, the operator (or user) typically presses the button 104 all the way down in one go, that is, the switch device 100 is switched off from the previous position. Figure 4A The state shown was directly pressed to Figure 4CThe state shown. During the pressing process, the switch device 100 is in... Figure 4B The press signal is generated when the device is in the middle position, as shown, to initiate a physical unlocking operation. The pressing process begins from... Figure 4B The intermediate state shown Figure 4C The time required for the shown completion state is the same as the time required for a physical unlocking operation (e.g., about 1 to 2 seconds). Throughout the process, the user feels that simply pressing button 104 all the way down unlocks the car door, allowing them to open it without waiting for additional time to unlock the door after pressing button 104.

[0045] Figure 5 This is an exploded view of a switching device according to a second embodiment of this application. To more clearly illustrate the differences between the second embodiment and the first embodiment, Figure 5 Concealed switch device: button cover, button, housing, and return spring.

[0046] Figure 5 The second embodiment shown is consistent with Figures 1 to 12. Figure 4C The difference in the first embodiment shown is only that, in Figures 1 to Figure 4C In the first embodiment of the switching device 100 shown, the intermediate element 110 includes two sets of sub-elements, while Figure 5 In the second embodiment of the switch device 500 shown, the intermediate element 510 includes only one set of sub-elements. Accordingly, the switch 512 only needs to be provided with a pressed part 513 and a triggered part 541, the switch device 500 only needs to be provided with a push rod 511, and the inner cover 508 only needs to be provided with a guide hole 535 to accommodate the push rod 511.

[0047] Those skilled in the art should also understand that, based on the same inventive concept as the previous embodiment, more than two sets of sub-elements can be provided on the intermediate element, and correspondingly, more than two pressed parts, more than two triggered parts, more than two push rods and more than two guide holes need to be provided.

[0048] Figures 6A-6C A schematic diagram showing the switch device installed on the vehicle door is provided. Figure 6A This is a schematic diagram of a vehicle equipped with the switching device described in this application; Figure 6B This is a partial perspective view of the switch device of this application installed on the vehicle door; Figure 6C This is a cross-sectional view along line DD of the switch device installed on the vehicle door according to this application.

[0049] like Figure 6AAs shown, the vehicle 600 has a handle device 610 disposed on a door 602 for opening the door 602. The handle device 610 is provided with a switch device described above, which is used to generate an unlock signal indicating that the door 602 is unlocked when a button is pressed.

[0050] like Figures 6B-6C As shown, the handle device 610 includes a handle base 611 having a handle cavity 612. A button 104 of the switch device 100 / 500 is disposed in the handle cavity 612 of the handle base 611, such that a pressing operation applied to the button 104 occurs within the handle cavity 612. Specifically, the handle cavity 612 has an upwardly curved cavity bottom wall 614 for guiding a user's finger into the handle cavity 612. When the user's finger is inserted inward and upward to the deepest position in the handle cavity 612, it can touch the button cover 102 of the switch device 100 / 500, thereby enabling an unlocking operation by pressing the button 104.

[0051] The vehicle 600 is also equipped with a control device (not shown in the figure) that can receive the unlocking signal transmitted by the switching device and control the locking lever to perform the unlocking operation.

[0052] The switching device of this application provides a button with a longer pressing stroke by incorporating an intermediate element, at least partially deformable, between the button and the pressed portion of the switch to transmit the pressing force. During button pressing, the switch is activated before the button is fully depressed, generating an unlocking signal. After the switch is activated, the intermediate element can deform to allow the button to continue moving a distance toward the switch; the time required for this process is the same as the time required for the lock lever to physically unlock. This compensates for the lag time in the lock lever unlocking operation, synchronizing the pressing completion time with the lock lever unlocking completion time. This allows users to open the car door without waiting for the lock lever to unlock after pressing the switch, resulting in a better user experience.
