Description

Technical Field

[0001] This application relates to the field of touch technology, and in particular to a touch switch module and a vehicle. Background Technology

[0002] With the development of technology, a technical solution has emerged that uses touch switches to open or close vehicle doors. However, during use, the touch switch needs to be constantly active to sense the user's touch actions, which results in relatively high overall power consumption. Summary of the Invention

[0003] Therefore, it is necessary to provide a touch switch module and carrier that can reduce power consumption to address the above-mentioned technical problems.

[0004] In a first aspect, this application proposes a touch switch module, comprising: a touch detection module for generating a touch signal based on a touch operation; a distance detection module for detecting the current distance to an object; and a main control board for communicatively connecting to both the touch detection module and the distance detection module. The main control board wakes up the touch detection module after obtaining that the current distance is less than a preset distance. The main control board generates a switch signal based on the touch signal, and the switch signal is used to instruct the door to be closed or opened.

[0005] Furthermore, it also includes: a vibration module, which is communicatively connected to the main control board, and the main control board is used to control the vibration module to vibrate after determining that the touch signal is a valid signal; and / or a backlight module, which is communicatively connected to the main control board, and the main control board is used to control the backlight module to switch the light emission color after determining that the touch signal is a valid signal.

[0006] Furthermore, after receiving a sleep command, the main control board controls at least one of the touch detection module, the vibration module, and the backlight module to enter sleep mode; after receiving a wake-up command, the main control board wakes up at least one of the touch detection module, the vibration module, and the backlight module.

[0007] Furthermore, after waking up the backlight module, the main control board controls the backlight module to continuously emit light in a first color; when the main control board detects that the touch detection module is being touched, it controls the backlight module to switch from a second color to a third color; after determining that the touch signal is a valid signal, the main control board controls the backlight module to emit light in a fourth color; and after determining that the touch signal is an invalid signal, the main control board controls the backlight module to emit light in a fifth color.

[0008] Furthermore, the touch detection module includes touch sensors disposed at multiple detection positions, and the multiple touch sensors are arranged in an array. The main control board is used to determine whether the touch operation is a sliding operation based on the triggering status of the touch sensors at the multiple detection positions, and outputs the switch signal when it is determined to be a sliding operation.

[0009] Furthermore, the touch detection module includes: a first sliding detection unit and a second sliding detection unit, both of which are provided with multiple detection positions, and each detection position is provided with a touch sensor; when the main control board detects that the touch sensors at the multiple detection positions in the first sliding detection unit are triggered sequentially in a first preset order, it outputs a door opening signal; when the main control board detects that the touch sensors at the multiple detection positions in the second sliding detection unit are triggered sequentially in a second preset order, it outputs a door closing signal.

[0010] Furthermore, the backlight module includes: a first backlight unit and a second backlight unit, wherein the first backlight unit is stacked with the first sliding detection unit, and the second backlight unit is stacked with the second sliding detection unit. When the main control board detects that the current distance is less than the preset distance and the door is in a closed state, it controls the first backlight unit to emit light; when the main control board detects that the current distance is less than the preset distance and the door is in an open state, it controls the second backlight unit to emit light.

[0011] Furthermore, the first sliding detection unit includes a first starting sensor, and when the main control board detects that the trigger time of the first starting sensor belongs to a first preset time period, it continues to detect the trigger state of the touch sensor set at each detection position in the first sliding detection unit; the second sliding detection unit includes a second starting sensor, and when the main control board detects that the trigger time of the second starting sensor belongs to a second preset time period, it continues to detect the trigger state of the touch sensor set at each detection position in the second sliding detection unit.

[0012] Furthermore, when the trigger time of the remaining touch sensors in the first sliding detection unit is less than a first preset time, the trigger state of the touch sensor is determined to be successfully triggered; when the trigger time of the remaining touch sensors in the second sliding detection unit is less than a second preset time, the trigger state of the touch sensor is determined to be successfully triggered.

[0013] Furthermore, the touch sensor includes a pressure detection component and a capacitance detection component. When the main control board detects that the pressure detection component is effectively triggered and the capacitance detection component is effectively triggered, it determines that the touch sensor has been triggered.

[0014] Furthermore, after the main control board receives the pressure signal sent by the pressure detection component, if the pressure signal is still within the preset range after a third preset time delay, it determines that the pressure detection component has been effectively triggered.

[0015] Furthermore, after the main control board detects that the pressure detection component and the capacitance detection component are effectively triggered, it stops detecting the signals sent by the pressure detection component or the capacitance detection component within a fourth preset time period.

[0016] Furthermore, the capacitance detection component includes a capacitance detection chip and a capacitor disk, wherein the capacitor disk is electrically connected to the signal detection terminal of the capacitance detection chip.

[0017] Furthermore, the capacitor disk is electrically connected to the signal detection terminal of the capacitor detection chip via a series filter resistor, and the filter resistor is positioned close to the signal detection terminal of the capacitor detection chip.

[0018] Furthermore, the capacitor disk is disposed in the enclosed area formed by the grounding wire, and the connection line between the capacitor disk and the signal detection terminal of the capacitor detection chip is surrounded by the grounding wire.

[0019] Secondly, this application also proposes a vehicle, including: a host and the touch switch module described in the first aspect embodiment above, wherein the host is communicatively connected to the main control board of the touch switch module.

[0020] The aforementioned touch switch module and vehicle, by incorporating a distance detection module within the touch switch module, detect the current distance between itself and an object. When the main control board detects that the current distance is less than a preset distance, it indicates that a user is approaching and a door-closing or opening operation is required. At this point, the main control board then wakes up the touch detection module, enabling it to generate a touch signal based on the user's touch operation. Upon receiving the corresponding touch signal, the main control board generates a switch signal to instruct the door to be closed or opened. This application's touch switch module only wakes up the touch detection module when a user is detected approaching, eliminating the need for real-time operation of the touch detection module and reducing the overall power consumption of the touch switch module.

Detailed Implementation

[0032] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be more thorough and complete.

[0033] In one embodiment, such as Figure 1 As shown, this application proposes a touch switch module, including: a touch detection module 110, a distance detection module 120, and a main control board 130. The touch detection module 110 is used to generate touch signals based on touch operations; the distance detection module 120 is used to detect the current distance between the device and an object; the main control board 130 is communicatively connected to the touch detection module 110 and the distance detection module 120 respectively. After the main control board 130 obtains that the current distance is less than a preset distance, it wakes up the touch detection module 110. The main control board 130 is used to generate a switch signal according to the touch signal, and the switch signal is used to indicate whether to close or open the car door.

[0034] Specifically, the touch switch module of this application is used to close or open the doors of a vehicle. When the touch detection module 110 is working, it can generate corresponding touch signals based on the user's touch operation and send these signals to the main control board 130. The touch detection module 110 can be based on capacitive and / or resistive sensing principles. When a user's finger or conductor touches its sensing area, its internal circuitry generates a change in electrical signal (such as a sudden change in capacitance or resistance), which is then converted into a digital / analog touch signal. The touch detection module 110 can be equipped with one or more touch sensors at detection locations to detect various touch operations.

[0035] The distance detection module 120 operates in real time, detecting the current distance to an object and sending the detected distance to the main control board 130. The distance detection module 120 can employ infrared sensors, ultrasonic sensors, etc., and can calculate the distance between the object and the distance detection module 120 based on the time taken to receive the reflected signal.

[0036] The main control board 130 is communicatively connected to the touch detection module 110 and the distance detection module 120, respectively, and is used to receive touch signals sent by the touch detection module 110 and the current distance sent by the distance detection module 120. The main control board 130 is a central processing unit, which integrates a microcontroller (MCU) for signal processing and logic judgment. In one embodiment of this application, the main control board 130 wakes up the touch detection module 110 after obtaining that the current distance is less than a preset distance, so that the touch detection module 110 can detect the user's touch operation. With this setting, it is not necessary to keep the touch detection module 110 working in real time, reducing the overall power consumption of the touch switch module. The preset distance can be adjusted according to specific usage needs. In some embodiments, the preset distance is set to 5cm to 20cm.

[0037] After receiving the touch signal from the touch detection module 110, the main control board 130 determines the characteristics of the touch signal (such as touch duration, number of touches, touch sequence, etc.) according to a preset program, and generates a corresponding switch signal. The main control board 130 sends the generated switch signal to the host of the vehicle, and the host will then close or open the door according to the received switch signal.

[0038] In one embodiment, such as Figure 2As shown, the touch switch module also includes a vibration module 140, which is communicatively connected to the main control board 130. The main control board 130 controls the vibration module 140 to vibrate after determining that the touch signal is valid. Specifically, the vibration module 140 can be a linear motor, piezoelectric ceramic vibrator, etc. The vibration module 140 is generally stacked with the touch detection module 110. When a certain area of ​​the touch detection module 110 is triggered by a touch operation, the touch detection module 110 sends a corresponding touch signal to the main control board 130. After receiving the corresponding touch signal, the main control board 130 determines whether it is a valid signal based on the characteristics of the touch signal (such as amplitude, duration, etc.). If the touch signal is determined to be valid, the main control board 130 controls the corresponding area of ​​the vibration module 140 to vibrate. The vibration module 140 can indicate different touch operations through vibration intensity, number of vibrations, vibration frequency, etc., which can be set according to specific usage needs. Through the haptic feedback settings of this embodiment, the intuitiveness of user interaction and the immediacy of operation feedback can be improved.

[0039] In one embodiment, such as Figure 2 As shown, the touch switch module also includes a backlight module 150, which is communicatively connected to the main control board 130. Specifically, the backlight module 150 can be composed of LED beads, driver circuits, and other functional modules. The backlight module 150 is generally stacked with the touch detection module 110. When a certain area of ​​the touch detection module 110 is triggered by a touch operation, the touch detection module 110 sends a corresponding touch signal to the main control board 130. After receiving the corresponding touch signal, the main control board 130 determines whether it is a valid signal based on the characteristics of the touch signal (such as amplitude and duration). If the touch signal is determined to be valid, it controls the backlight module 150 to switch the emitted light color. The backlight module 150 can indicate different touch operations through the emitted light color and flashing frequency, and it can be set according to specific usage needs. Through the visual feedback settings of this embodiment, the intuitiveness of user interaction and the immediacy of operation feedback can be improved.

[0040] In one embodiment, such as Figure 2 As shown, the touch switch module can simultaneously be equipped with a vibration module 140 and a backlight module 150. The main control board 130 is used to control the backlight module 150 to switch the light emission color and control the vibration module 140 to vibrate after receiving a touch signal. Through the dual feedback of tactile and visual feedback, the intuitiveness of user interaction and the immediacy of operation feedback can be further improved.

[0041] In one embodiment, after receiving a sleep command, the main control board 130 controls at least one of the touch detection module 110, vibration module 140, and backlight module 150 to enter sleep mode. Specifically, in this embodiment, the functional modules in the touch switch module can be actively controlled to enter sleep mode, thereby further reducing power consumption. The host of the vehicle can actively send a sleep command to the main control board 130. For example, if no user operation is detected within a preset time, the host will actively send a sleep command to the main control board 130. After receiving the sleep command, the main control board 130 will control at least one of the touch detection module 110, vibration module 140, and backlight module 150 to enter sleep mode. In this embodiment, the distance detection module 120 and the main control board 130 are not in sleep mode. When the main control board 130 obtains that the current distance is less than a preset distance, it can wake up at least one of the touch detection module 110, vibration module 140, and backlight module 150.

[0042] In some embodiments, the distance detection module 120, which is in a normally operating state, can control whether the main control board 130 is in sleep mode, thereby indirectly controlling whether other electronic modules such as the touch detection module 110, vibration module 140, and backlight module 150 are in sleep mode.

[0043] In one embodiment, upon receiving a wake-up command, the main control board 130 wakes up at least one of the touch detection module 110, vibration module 140, and backlight module 150. Specifically, in this embodiment, it can actively wake up the functional modules in the touch switch module that have entered sleep mode, thereby enabling the touch switch module to perform the corresponding touch functions normally. In some other embodiments, when the main control board 130 enters a low-power mode, it will control itself to enter the normal working mode upon receiving a wake-up command.

[0044] In one embodiment, after waking up the backlight module 150, the main control board 130 controls the backlight module 150 to continuously emit light in a first color. Specifically, in this embodiment, the backlight module 150 will continuously emit light after being woken up to indicate its current status. The first color can be set according to specific needs. For example, after being woken up, the backlight module 150 will continuously emit light in a bright white.

[0045] In one embodiment, when the main control board 130 detects that the touch detection module 110 is being touched, it controls the backlight module 150 to switch from emitting light in a second color to a third color. Specifically, in this embodiment, when the user touches the touch detection module 110, the main control board 130 controls the backlight module 150 to switch from emitting light in a second color to a third color. The second and third colors can be set according to specific needs. For example, when the user first touches the touch detection module 110, the backlight module 150 emits blue light, and during the operation, it gradually changes from blue light to green light.

[0046] In one embodiment, after determining that the touch signal is valid, the main control board 130 controls the backlight module 150 to emit light in a fourth color; after determining that the touch signal is invalid, the main control board 130 controls the backlight module 150 to emit light in a fifth color. Specifically, when a user performs a touch operation on the touch detection module 110, the touch detection module 110 generates a corresponding touch signal. After the main control board 130 determines that the touch signal is valid based on its characteristics (such as amplitude and duration), it controls the backlight module 150 to emit light in the fourth color. After the main control board 130 determines that the touch signal is invalid based on its characteristics (such as amplitude and duration), it controls the backlight module 150 to emit light in the fifth color. The fourth and fifth colors can be set according to specific needs. In one embodiment, the fourth color can be set to the same as the third color. For example, the first color is set to white light, the second color is set to blue light, the third color is set to green light, the fourth color is set to green light, and the fifth color is set to red light. After the main control board 130 determines that the touch signal is a valid signal, it will control the backlight module 150 to emit green light; after the main control board 130 determines that the touch signal is an invalid signal, it will control the backlight module 150 to emit red light.

[0047] In one embodiment, such as Figure 3As shown, the touch detection module 110 includes touch sensors disposed at multiple detection positions. The touch sensors at these multiple detection positions are arranged in an array. The main control board 130 is used to determine whether a touch operation is a swipe operation based on the triggering status of the touch sensors at the multiple detection positions, and outputs a switch signal if a swipe operation is determined to be one. Specifically, when using a single touch sensor for touch detection, the touch detection module 110 is easily subjected to heavy water (such as during car washing or rain), which can lead to simultaneous triggering of pressure and / or capacitance, resulting in false triggering. In this embodiment, the touch detection module 110 is constructed by using multiple arranged touch sensors (touch sensor 1, touch sensor 2, ..., touch sensor n) to determine whether a touch operation is a swipe operation, thereby greatly reducing false triggering of the touch detection module 110. Each touch sensor in the touch detection module 110 is communicatively connected to the main control board 130. The main control board 130 determines the trigger status of the corresponding touch sensor based on the touch signals sent by the touch sensors. By detecting the trigger status of all touch sensors, the main control board 130 can determine whether the user's current touch operation is a swipe operation, and outputs a switch signal to close or open the car door if a swipe operation is determined. In some embodiments, the specific path of the swipe operation can also be determined by combining the trigger times of the touch sensors. It is understood that during a swipe operation, the touch sensors in the touch detection module 110 are triggered sequentially. The arrangement of the touch sensors at multiple detection positions can be configured according to specific usage requirements. For example, the touch sensors at multiple detection positions can be arranged in a straight line, a curve, or an array.

[0048] In one embodiment, such as Figure 4 As shown, the touch detection module 110 includes: a first sliding detection unit 111 and a second sliding detection unit 112. Both the first sliding detection unit 111 and the second sliding detection unit 112 are provided with multiple detection positions, and each detection position is provided with a touch sensor. When the main control board 130 detects that the touch sensors at the multiple detection positions in the first sliding detection unit 111 are triggered sequentially in a first preset order, it outputs a door opening signal. When the main control board 130 detects that the touch sensors at the multiple detection positions in the second sliding detection unit 112 are triggered sequentially in a second preset order, it outputs a door closing signal.

[0049] Specifically, in this embodiment, a touch detection module 110, including a first sliding detection unit 111 and a second sliding detection unit 112, is used to determine whether the output signal is a door opening signal or a door closing signal. In some embodiments, the arrangement direction of the first preset order can be set to be the same as the door opening direction, and the arrangement direction of the second preset order can be set to be the same as the door closing direction.

[0050] In some embodiments, upon receiving a wake-up command, the main control board 130 wakes up the first sliding detection unit 111 and the second sliding detection unit 112. In other embodiments, the main control board 130 may selectively wake up either the first sliding detection unit 111 or the second sliding detection unit 112 based on the current state of the door. For example, when the door is closed, only the first sliding detection unit 111 is woken up to perform the door opening operation; when the door is open, only the second sliding detection unit 112 is woken up to perform the door closing operation.

[0051] The first sliding detection unit 111 has multiple detection positions (M1, M2, ..., Mn), and the second sliding detection unit 112 has multiple detection positions (N1, N2, ..., Nn). Adjacent detection positions in the first sliding detection unit 111 and the second sliding detection unit 112 can share the same touch sensor. For example, see [reference needed]. Figure 6 Detection positions M1 and N1 can each be equipped with only one touch sensor. The first sliding detection unit 111 and the second sliding detection unit 112 can be arranged at different positions at intervals, or staggered in the same area. When the main control board 130 detects that the touch sensors at multiple detection positions in the first sliding detection unit 111 are triggered sequentially in a first preset order (such as M1—M2—……—Mn), it outputs a door opening signal. When the main control board 130 detects that the touch sensors at multiple detection positions in the second sliding detection unit 112 are triggered sequentially in a second preset order (such as Nn—……—N2—N1), it outputs a door closing signal.

[0052] In one embodiment, when the main control board 130 detects that the touch sensors at multiple detection positions in the first sliding detection unit 111 are not triggered sequentially in a first preset order, it outputs an invalid operation signal; when the main control board 130 detects that the touch sensors at multiple detection positions in the second sliding detection unit 112 are not triggered sequentially in a second preset order, it outputs an invalid operation signal. Specifically, if the first preset order is set to M1—M2—…—Mn, and the main control board 130 detects that the triggering order of the touch sensors at multiple detection positions is: M2—…—Mn; M1—M3—…—Mn; M2—M1—…—Mn; and they are not triggered sequentially in the first preset order, then the user's sliding operation is invalid, and the main control board 130 outputs an invalid operation signal. The invalid operation signal indicates that the current sliding operation is invalid. If the second preset sequence is set to Nn—……—N2—N1, and the main control board 130 detects that the triggering sequence of multiple touch sensors at the detection positions is: N3—……—Nn; N1—N4—……—Nn; N3—N2—……—Nn; and they are not triggered in the second preset sequence, then the user's swipe operation is invalid, and the main control board 130 also outputs an invalid operation signal.

[0053] In one embodiment, when the main control board 130 outputs an invalid operation signal, it can also control the vibration module 140 to perform a preset vibration operation (such as continuous vibration, rapid vibration, etc.) and / or control the backlight module 150 to perform a preset light emission operation (such as displaying red light, rapid flashing, etc.) to prompt the user that the current sliding operation is invalid.

[0054] In one embodiment, such as Figure 5 As shown, the backlight module 150 includes: a first backlight unit 151 and a second backlight unit 152. The first backlight unit 151 is stacked with the first sliding detection unit 111, and the second backlight unit 152 is stacked with the second sliding detection unit 112. When the main control board 130 detects that the current distance is less than a preset distance and the door is in a closed state, it controls the first backlight unit 151 to emit light; when the main control board 130 detects that the current distance is less than a preset distance and the door is in an open state, it controls the second backlight unit 152 to emit light.

[0055] Specifically, in this embodiment, when the touch detection module 110 is provided with a first sliding detection unit 111 and a second sliding detection unit 112, the backlight module 150 is also correspondingly provided with a first backlight unit 151 and a second backlight unit 152. The first backlight unit 151 is stacked with the first sliding detection unit 111 to form the backlight of the first sliding detection unit 111 when it emits light. The second backlight unit 152 is stacked with the second sliding detection unit 112 to form the backlight of the second sliding detection unit 112 when it emits light. In one embodiment, when the main control board 130 detects that the current distance is less than a preset distance and the car door is in the closed state, it controls the first backlight unit 151 to emit light, thereby instructing the user to open the car door through the first sliding detection unit 111. When the main control board 130 detects that the current distance is less than a preset distance and the car door is in the open state, it controls the second backlight unit 152 to emit light, thereby instructing the user to close the car door through the second sliding detection unit 112.

[0056] In one embodiment, the first sliding detection unit 111 includes a first starting sensor. When the main control board 130 detects that the trigger time of the first starting sensor belongs to a first preset time period, it continues to detect the trigger status of the touch sensors set at each detection position in the first sliding detection unit 111. Specifically, in this embodiment, when a user opens a car door through the first sliding detection unit 111, the first starting sensor needs to be continuously triggered, and subsequent sliding operations can only be performed if the trigger time belongs to the first preset time period, in order to further reduce the possibility of accidental touches by the user. If the trigger time of the first starting sensor does not belong to the first preset time period, the main control board 130 will stop detecting the trigger status of the touch sensors set at each detection position in the first sliding detection unit 111. The first preset time period can be set according to specific usage needs. In some embodiments, the first preset time period is set to 1 second to 3 seconds.

[0057] In one embodiment, when the trigger time of the touch sensor at each detection position in the first sliding detection unit 111 is less than a first preset time, the trigger state of the touch sensor is determined to be successfully triggered. Specifically, in this embodiment, when detecting the trigger state of the touch sensor at each detection position in the first sliding detection unit 111, the trigger time is also determined. If the trigger time of the corresponding touch sensor is less than the first preset time, the trigger state of the corresponding touch sensor is determined to be successfully triggered. By determining the trigger time, false triggers caused by external environmental factors (such as water flow, rubbing, etc.) can be reduced. In some embodiments, the first preset time is set to 50ms.

[0058] In one embodiment, the second sliding detection unit 112 includes a second start sensor. When the main control board 130 detects that the trigger time of the second start sensor belongs to a second preset time period, it continues to detect the trigger status of the touch sensors set at each detection position in the second sliding detection unit 112. Specifically, in this embodiment, when a user closes a door using the second sliding detection unit 112, the second start sensor must be continuously triggered, and subsequent sliding operations can only be performed if the trigger time belongs to the second preset time period, thereby further reducing the possibility of accidental touches by the user. If the trigger time of the second start sensor does not belong to the second preset time period, the main control board 130 will stop detecting the trigger status of the touch sensors set at each detection position in the second sliding detection unit 112. The second preset time period can be set according to specific usage needs, and the second preset time period can be the same as or different from the first preset time period. In some embodiments, the second preset time period is set to 1 second to 3 seconds.

[0059] In one embodiment, when the trigger time of the touch sensor at each detection position in the second sliding detection unit 112 is less than a second preset time, the trigger state of the touch sensor is determined to be successfully triggered. Specifically, in this embodiment, when detecting the trigger state of the touch sensor at each detection position in the second sliding detection unit 112, the trigger time is also determined. If the trigger time of the corresponding touch sensor is less than the second preset time, the trigger state of the corresponding touch sensor is determined to be successfully triggered. By determining the trigger time, false triggers caused by external environmental factors (such as water flow, friction, etc.) can be reduced. In some embodiments, the second preset time is set to 50ms.

[0060] The touch switch module of this application is described in detail below with reference to a specific embodiment. Figure 6 The diagram shows the layout of the touch sensors in the touch detection module 110 in one embodiment. The first slide detection unit 111 of the touch detection module 110 has one starting position and three detection positions, P1, M1, M2, and M3, where a first starting sensor is located at P1. Similarly, the second slide detection unit 112 of the touch detection module 110 also has one starting position and three detection positions, P2, N1, N2, and N3, where a second starting sensor is located at P2. It can be understood that... Figure 6 The shapes shown are transparent icons set on the surface. When the backlight module 150 emits light, the corresponding icons will be displayed through the backlight. The first sliding detection unit 111 is also provided with a first backlight unit 151, and the second sliding detection unit 112 is also provided with a second backlight unit 152.

[0061] The first backlight unit 151 is respectively set to positions P1, M1, M2, and M3, and the second backlight unit 152 is respectively set to positions P2, N1, N2, and N3. The first backlight unit 151 and the second backlight unit 152 can be set as one unit or separately. When the touch detection module 110 is woken up and the main control board determines that the user has a need to open the door, it controls the first backlight unit 151 to emit white light and the second backlight unit 152 to not emit light, so as to indicate the position of the first sliding detection unit 111 to the user. When the touch detection module 110 is woken up and the main control board determines that the user has a need to close the door, it controls the second backlight unit 152 to emit white light and the first backlight unit 151 to not emit light, so as to indicate the position of the second sliding detection unit 112 to the user.

[0062] When a user touches the first initiation sensor P1 and the touch time is within the first preset time period (2 seconds), the first backlight unit 151 emits blue light, and the vibration module 140 vibrates at the corresponding position. At this time, the user can slide along the sequence P1—M1—M2—M3. The first backlight unit 151 switches from blue light to green light at each detection position following the sliding sequence. After the main control board 130 detects that P1, M1, M2, and M3 are triggered in this order, it outputs an opening signal and controls the first backlight unit 151 to emit green light. If the triggering is not in this order, it outputs an invalid operation signal and controls the first backlight unit 151 to emit red light. When a user touches the second start sensor P2 and the touch time is within the second preset time period (2 seconds), the second backlight unit 152 emits blue light, and the vibration module 140 vibrates at the corresponding position. At this time, the user can slide along the sequence P2—N3—N2—N1. The second backlight unit 152 switches from blue light to green light at each detection position following the sliding sequence. After the main control board 130 detects that P1, N3, N2, and N1 are triggered in this order, it outputs a door closing signal and controls the second backlight unit 152 to emit green light. If the triggering is not in this order, it outputs an invalid operation signal and controls the second backlight unit 152 to emit red light.

[0063] In one embodiment, the touch sensor includes a pressure detection component and a capacitance detection component. The main control board 130 determines that the touch sensor has been triggered when it detects that both the pressure detection component and the capacitance detection component are effectively triggered. Specifically, since vehicle exteriors and interior surfaces near windows are prone to water droplets or flow, capacitive touch is prone to misjudgments in such scenarios. Furthermore, since the detection principle of capacitive touch is based on the PAD detecting the change in dielectric constant of the surrounding environment over a short period to determine if a touch action has occurred, it is also prone to responding when objects with low impedance or dielectric constants similar to those of the human body (such as water, aluminum, iron, etc.) are nearby. Therefore, the touch sensor of this application is composed of both a pressure detection component and a capacitance detection component. The main control board 130 is communicatively connected to both the pressure detection component and the capacitance detection component. The main control board 130 only determines that the touch sensor has been triggered when it detects that both the pressure detection component and the capacitance detection component are effectively triggered, thereby reducing false triggering of the touch sensor. The main control board 130 determines that the pressure detection component is effectively triggered only when it detects that the pressure value sent by the pressure detection component is greater than a preset pressure value (e.g., 4N to 8N). Similarly, the main control board 130 determines that the capacitance detection component is effectively triggered only when it detects a sudden change in the capacitance value. For example, if the capacitance detection component is self-capacitive, touching it will cause the capacitance value to increase; if the capacitance detection component is mutual-capacitive, touching it will cause the capacitance value to decrease.

[0064] In one embodiment, after receiving the pressure signal from the pressure detection component, the main control board 130 determines that the pressure detection component has been effectively triggered if the pressure signal remains within a preset range after a third preset time delay. Specifically, in this embodiment, after receiving the pressure signal from the pressure detection component, the main control board 130 delays for a third preset time (e.g., 5ms) before judging the current pressure signal. If the pressure signal remains within a preset range (e.g., 4N to 8N), the pressure detection component is determined to be effectively triggered. Through the judgment steps of this embodiment, the pressure signal can be de-jittered, thereby filtering out interference signals caused by environmental factors such as car washing and heavy rain.

[0065] In one embodiment, after detecting that the pressure detection component and the capacitance detection component are effectively triggered, the main control board 130 stops detecting the signals sent by the pressure detection component or the capacitance detection component within a fourth preset time. Specifically, based on the application scenario of the touch switch module, when applied to the closing or opening of the car door, the user generally does not perform continuous closing and opening operations on the car door. Therefore, after detecting that the pressure detection component and the capacitance detection component are effectively triggered, the main control board 130 stops detecting the signals sent by the pressure detection component or the capacitance detection component within a fourth preset time (e.g., 3 seconds), and does not process the sent signals, treating them as interference signals.

[0066] In one embodiment, such as Figure 7 As shown, the capacitance detection component includes a capacitance detection chip 101 and a capacitor disk 102, with the capacitor disk 102 electrically connected to the signal detection terminal of the capacitance detection chip 101. Specifically, in this embodiment, capacitance detection is performed through a combination of the capacitance detection chip 101 and the capacitor disk 102.

[0067] In one embodiment, such as Figure 8 The diagram shows the wiring schematic of the capacitance detection chip 101 and the capacitor bank 102. By reducing the length of the connection line between the capacitor bank 102 and the signal detection terminal of the capacitance detection chip 101, i.e. Figure 8 Position 2 in the middle can reduce noise interference and improve the signal-to-noise ratio.

[0068] In one embodiment, such as Figure 8 As shown, the capacitor disk 102 is electrically connected to the signal detection terminal of the capacitor detection chip 101 via a series filter resistor, which is positioned close to the signal detection terminal of the capacitor detection chip 101. Specifically, in this embodiment, by connecting a filter resistor in series between the capacitor disk 102 and the signal detection terminal of the capacitor detection chip 101, i.e., the resistor positioned at R27 in the figure, a low-pass RC filter can be formed, thereby reducing the amplitude of RF noise coupled to the signal detection terminal of the capacitor detection chip 101. Furthermore, by positioning the filter resistor close to the signal detection terminal of the capacitor detection chip 101, radiated noise caused by the connecting wires can be filtered out at the signal detection terminal.

[0069] In one embodiment, such as Figure 8As shown, the capacitor disk 102 is disposed in the enclosed area formed by the grounding wire, and the connection line between the capacitor disk 102 and the signal detection terminal of the capacitance detection chip 101 is surrounded by the grounding wire. Specifically, the grounding wire is configured as a grid, and its connection line with the capacitor disk 102 and the capacitance detection chip 101 is disposed on different layers of the PCB (Printed Circuit Board). The grounding wire forms an enclosed area to surround the capacitor disk 102, as shown at position 3 in the figure. Furthermore, the connection line between the capacitor disk 102 and the signal detection terminal of the capacitance detection chip 101 is surrounded by grounding wires on both upper and lower layers, thereby reducing RF radiation and interference. It can be understood that, at locations far from the capacitance detection chip 101 and the capacitor disk 102, the grounding wire can be replaced with a solid grounding layer. In some embodiments, the line width of the grounding wire is set to 8 mil.

[0070] In one embodiment, this application also proposes a vehicle, which includes the touch switch module and the host as described in the above embodiments. The host is communicatively connected to the main control board 130 of the touch switch module. The host can send a sleep command or a wake-up command to the main control board 130, and the host can also receive a switch signal sent by the main control board 130. After receiving the switch signal, the host will control the door switch in the vehicle, thereby closing or opening the door.

[0071] The means of transportation can include land vehicles, water vehicles, air vehicles, industrial equipment, agricultural equipment, or recreational equipment. For example, a means of transportation can be a vehicle, which is a vehicle in a broad sense, including transportation vehicles (such as commercial vehicles, passenger cars, motorcycles, flying cars, trains, etc.), industrial vehicles (such as forklifts, trailers, tractors, etc.), engineering vehicles (such as excavators, bulldozers, cranes, etc.), agricultural equipment (such as lawnmowers, harvesters, etc.), amusement equipment, toy vehicles, etc. The embodiments of this application do not specifically limit the type of vehicle. As another example, a means of transportation can be an airplane or a ship.
