Description

Technical Field

[0001] The present invention relates to the technical field of gear shifting, and more particularly to an automotive gear shift switch and system with a touch sensing function. Background Art

[0002] There are two forms of gear lever arrangements in automobiles: floor-mounted and steering column-mounted. When the automotive gear lever is located at the lower right of the steering wheel, it is called a steering column-mounted gear lever.

[0003] For example, the disclosed Chinese Utility Model Patent No. CN212004204U discloses an automotive steering column-mounted gear shift switch, which includes a handle (30) for switching gears. The gears that the handle (30) can switch to include the drive gear D, reverse gear R, neutral gear N, and the home position H. The drive gear D, reverse gear R, and neutral gear N are located on the X-axis, and the neutral gear N and the home position H are located on the Y-axis. In the automotive steering column-mounted gear shift switch of the present utility model, the drive gear D, reverse gear R, and neutral gear N are arranged on the X-axis, and the neutral gear N and the home position H are arranged on the Y-axis. When switching gears, it is necessary to first move the handle along the Y-direction from the home position to the neutral gear N on the X-axis, and then switch to the drive gear D or reverse gear R along the X-direction. The operation feedback is more obvious and misoperation will not occur.

[0004] However, when switching from the N gear to the D gear, the above-mentioned gear shift switch does not require stepping on the brake. If an object falls above and accidentally touches the gear shifter, it may cause the vehicle to enter the D gear (drive gear) state from the current N gear (neutral gear), thus driving the vehicle forward, which will also have a great impact on the safety of the driver.

[0005] Based on this, the present invention designs an automotive gear shift switch and system with a touch sensing function to solve the above problems. Summary of the Invention

[0017] Furthermore, the rotating component includes a hemispherical housing, a rotating limiting groove and a rotating support column. The rotating support column is fixedly connected to the end of the support housing close to the lever. The hemispherical housing is provided with a rotating limiting groove at the end close to the support housing, which is in sliding connection with the rotating support column in a fitting manner. The outer wall of the hemispherical housing is in sliding connection with the inner walls of the first semi - circular limiting ring and the second semi - circular limiting ring in a fitting manner.

[0018] A control system of an automotive shift switch with a touch - type sensing function includes a controller.

[0050] A P gear button is installed at the end of the lever away from the mounting seat;

[0051] A contact sensing module is installed on the top of the end of the lever away from the mounting seat;

[0052] The contact sensing module uses a capacitive touch sensor;

[0053] The rotating assembly will be installed in the first semicircular limiting ring of the mounting seat, the rear cover assembly will be docked with the supporting shell, and then the clamping assembly will connect the rear cover assembly against the supporting shell to facilitate the quick installation of the rear cover assembly, push the lever, and the first semicircular limiting ring, the rear cover assembly and the rotating assembly will cooperate to start the guide for the lever to be pushed, so as to facilitate the vertical movement of the lever. When the lever needs to be pushed downward, the contact sensing module can sense whether it is a human operation. If it is not sensed that it is a human operation, the control system will control the lever not to be pushed downward. If it senses human operation, the control system will control the lever to be pushed downward, so as to avoid the car entering the D gear (forward gear) from the current N gear (neutral gear) due to objects falling from the top of the lever and hitting the lever, thereby protecting the safety of the driver and the car.

[0054] The rear cover assembly includes a rear cover plate, a second semicircular limiting ring and a side plate. The end of the rear cover plate close to the lever is fixedly connected to the side plate. The end of the side plate close to the lever is fixedly connected to the second semicircular limiting ring. When the second semicircular limiting ring contacts the first semicircular limiting ring, a complete set of circular rings is formed.

[0055] The rear cover plate of the rear cover assembly is fitted and contacted with the support shell, and the side plate drives the second semicircular limiting ring to contact with the first semicircular limiting ring. When the second semicircular limiting ring contacts with the first semicircular limiting ring, a complete set of circular rings is formed, and the complete circular rings rotate and lock the rotating assembly;

[0056] The snap - fit assembly includes a limit plate, a snap block and a snap buckle. Limit plates are fixedly connected to both the upper and lower ends of the end of the support housing close to the lever. A snap block is fixedly connected to the rear side wall of the end of the support housing close to the lever. A snap buckle for cooperating with the snap block is fixedly connected to the front side wall of the rear cover plate;

[0057] When the side plate drives the second semi - circular limit ring to contact the first semi - circular limit ring, the upper end of the side plate moves to the bottom of the upper limit plate, and the lower end of the side plate moves to the top of the lower limit plate. At the same time, the snap block and the snap buckle are snap - connected, and the snap - fit assembly facilitates the installation of the rear cover assembly on the mounting seat;

[0060] The lever drives the hemispherical housing to rotate within the first semi - circular limit ring and the second semi - circular limit ring. The rotating support column and the rotating limit groove cooperate to rotate the hemispherical housing along the center of the rotating support column in the vertical direction.

[0061] Embodiment

[0062] As shown in the figure, a control system of an automotive shift switch with touch - type sensing function includes a controller;

[0063] The controller is connected to a processing module, a locking module, a fingerprint sensing module, a pressure sensing module and an intelligent transmission system;

[0064] The controller is connected to the contact sensing module.

[0065] The controller is also connected to a storage module.

[0066] The locking module is installed in the support housing, and the locking module is inserted into the rotating assembly.

[0067] The locking module selects a push - pull electromagnet, and the hemispherical housing is provided with a jack for the push - rod of the push - pull electromagnet.

[0068] After the contact sensing module is powered on and senses the human skin, the push - rod of the push - pull electromagnet separates from the hemispherical housing, and the rotating assembly can rotate freely;

[0069] The intelligent transmission system includes an input module, an output module, and a mobile phone APP. The controller is connected to both the input module and the output module, and the mobile phone APP is connected to the input module and the output module via wireless signals.

[0070] There are two groups of fingerprint sensing modules. One group of fingerprint sensing modules is installed at the door lock of the driver's seat in the car, and the other group of support sensing modules is fixedly installed inside the button for one-touch start of the car, and the sensing ends of the fingerprint sensing modules are exposed.

[0071] The pressure sensing module is a pressure sensor, and the pressure sensing module is installed on the driver's seat.

[0072] Any one of the fingerprint sensing modules records the fingerprint information of the driver, transmits the fingerprint information to the output module of the intelligent transmission system, and then to the mobile phone APP. The car owner matches and records the driver's identity information and fingerprint information one by one on the mobile phone APP, registers the driver as a regular driver, and transmits it to the controller through the input module, and then to the storage module for storage. When the regular driver forgets to bring the key, the car can be started normally.

[0073] When the car is in the locked state and the fingerprint sensing module at the door lock of the driver's seat in the car senses the fingerprint information, the fingerprint information is transmitted to the processing module through the controller. The processing module traverses and compares the fingerprint information stored in the storage module. When there is a match, the controller gives the car an unlocking message and the car unlocks. When the regular driver forgets to bring the key, the car can be started normally. When there is no match, the processing module sends an abnormal message, and the controller transmits the abnormal message to the output module of the intelligent transmission system, and then to the mobile phone APP. The car owner confirms whether to unlock on the mobile phone APP. When confirming to unlock, the unlocking instruction is sent to the controller through the input module, and the controller gives the car an unlocking message and the car unlocks. When confirming not to unlock, the non-unlocking instruction is sent to the controller through the input module, and the controller gives the car a non-unlocking message and the car remains locked all the time, remotely controlling whether a driver without fingerprint entry is allowed to enter the vehicle.

[0074] After the pressure sensing module senses that the driver has sat on the driver's seat, the controller powers on the fingerprint sensing module inside the one-key start button. The fingerprint sensing module inside the one-key start button senses the fingerprint information, and then transmits the fingerprint information to the processing module through the controller. The processing module compares the fingerprint information sensed by the fingerprint sensing module at the door lock of the main driver of the vehicle. If they are the same, the controller powers on the contact sensing module, indicating that the person entering the main driver is the person approved by the vehicle owner. If they are different, the controller does not power on the contact sensing module, indicating that the person entering the main driver is not the person approved by the vehicle owner. When the vehicle is powered on, the identity of the person in the main driver is verified again to prevent unauthorized personnel from operating the vehicle. After the contact sensing module is powered on, when the contact sensing module senses the human skin, it powers on the push-pull electromagnet. The insertion rod of the push-pull electromagnet separates from the hemispherical housing, and the rotating assembly can rotate freely, and the vehicle can drive normally. When the contact sensing module does not sense the human skin, it does not power on the push-pull electromagnet, and the insertion rod of the push-pull electromagnet is inserted into the hemispherical housing to lock the hemispherical housing, and the rotating assembly cannot rotate, and the vehicle cannot drive. The contact sensing module can sense whether the human skin is in contact with the contact sensing module, so as to judge whether it is a human operation. If it does not sense a human operation, the control system gives a control that the lever cannot be pushed down. If it senses a human operation, the control system gives a control that the lever is pushed down, which can prevent the vehicle from entering the D gear (forward gear) state from the current N gear (neutral gear) due to an object falling above the lever and hitting the lever, protecting the safety of the driver and the vehicle.

[0075] In summary, when the regular driver forgets to bring the key, the vehicle can be started normally; remote control can be realized to determine whether a driver without a fingerprint registered is allowed to enter the vehicle; at the same time, when the vehicle is powered on, the identity of the person in the main driver is verified again to prevent unauthorized personnel from operating the vehicle; in addition, the contact sensing module 7 can sense whether the human skin is in contact with the contact sensing module 7, so as to judge whether it is a human operation. If it does not sense a human operation, the control system gives a control that the lever 6 cannot be pushed down. If it senses a human operation, the control system gives a control that the lever 6 is pushed down, which can prevent the vehicle from entering the D gear (forward gear) state from the current N gear (neutral gear) due to an object falling above the lever 6 and hitting the lever 6, protecting the safety of the driver and the vehicle.

[0076] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements will not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
