Detailed Description

The advantages of the invention are further illustrated in the following description of specific embodiments in conjunction with the accompanying drawings.

As shown in fig. 1, the present invention includes a key fob for a vehicle as a remote controller for controlling a start, a shutdown, and other functions of the vehicle, including a housing 1, a mechanical key 2, the mechanical key 2 being disposed in the housing 1, a transceiver and a sensor being disposed in the mechanical key 2, the housing 1 including a display device 12 and a control unit, the sensor activating the display device 12 when sensing that the mechanical key 2 is touched, the display device 12 being capable of displaying information or a control menu of the vehicle, the mechanical key 2 serving as an input device accessing the menu of the display device 12 to generate an input command. The control unit is in communication connection with the display device 12, and in one embodiment, the control unit generates control information after receiving an input instruction and sends the control information to the automobile controller, so as to control the automobile; in another embodiment, the control unit receives the input command and controls the display device to display the state information of the automobile according to the input command.

As shown in fig. 2, the mechanical key 2 includes a pen tip 21, a pen barrel 22 and a holding portion 23, the holding portion 23 and the pen tip 21 are respectively located at two ends of the pen barrel 22, the pen tip 21 is used for contacting the display device 12 to access a menu of the display device 12, a pressure sensing device is arranged in the holding portion 23, the pressure sensing device integrates the transceiver and the sensor, and the pressure sensing device activates the display device 12 when sensing pressure. By means of the sensor in the pressure-sensing device, the mechanical key 2 is able to recognize the pressure acting on the grip 23, and thus to transmit the pressure-generated corresponding pressure information to the control unit of the housing 1 of the key fob via the transceiver, thereby controlling the activation and deactivation of the display device 12. This kind of configuration can save the operation step of opening display device on the one hand for user's experience is better, and the key fob is more careful, on the other hand can ensure display device 12's life, and under the condition that does not use mechanical key 2, display device 12 is not activated, can prevent the production of maloperation. Furthermore, a fingerprint recognition device can be integrated into the grip portion 23, thereby further improving the security of the remote control key.

As shown in fig. 3, the housing 1 includes a housing space 11 for housing the mechanical key 2, the housing space 11 includes a long straight groove having a shape matching the pen tip 21 and the pen barrel 22, and an extension opening having a shape matching the grip portion 23 and communicating with the long straight groove, the pen tip 21 and the pen barrel 22 are housed in the long straight groove, and the grip portion 23 is housed in the extension opening. The above-described configuration in which the housing space 11 is configured to match the shape of the mechanical key 2 is intended to allow the mechanical key 2 to be fitted into the housing 1 when the mechanical key 2 is not in use, thereby protecting the mechanical key 2 and eliminating the trouble of the user in locating and storing the mechanical key 2. In order to better clamp and insert the mechanical key 2, a tiny protrusion may be disposed at the bottom end of the long straight groove of the accommodating space 11, and the mechanical key 2 is clamped and fixed by matching with the key bit on the side surface of the pen holder 22 of the mechanical key 2. The grip portion 23 of the mechanical key 2 is inserted into the extended opening so that its outer surface is flush with the surface of the housing 1 for the sake of the aesthetic appearance of the key fob as a whole.

As shown in fig. 4, the operation principle of the key fob is as follows: when the user needs to use the key fob and extract the mechanical key 2, the sensor provided in the grip portion 23 can sense pressure from the user's finger, and once the user's finger applies pressure to the grip portion 23, the sensor transmits information of the pressure sensed by the sensor to a control unit provided in the housing 1 of the key fob serving as a remote controller via, for example, a low frequency signal (low frequency RF), and the control unit converts the information of the pressure into control information upon receiving the information of the pressure, thereby activating the display device 12. The entire process can be completed with no additional action required by the user simply pulling the mechanical key 2 and applying a slight pressure to the grip portion 23. When the user does not use the mechanical key 2 any more or the mechanical key 2 is replaced into the accommodating space 11 again, the sensor can generate no-pressure information to the transceiver due to the fact that the holding part 23 does not sense any pressure, the no-pressure information is sent to the control unit by the transceiver, the control unit converts the no-pressure information into closing information, the display device 12 is closed and is in an inactivated state, the setting can prevent the display device 12 from being activated by mistake due to misoperation of the user, safety performance is improved, electricity is saved, and service life of the battery is prolonged. When the mechanical key 2 is not in use, it is accommodated in the accommodation space 11 of the remote control key.

Preferably, the display device 12 is used to display the position of the car, the amount of oil, the temperature, and status information for turning on and off the air conditioner. More preferably, the control information output by the display device 12 may be used to control unlocking, ignition or reverse/forward movement of the vehicle. The display of the control information can ensure that a user can clearly know the important information of the automobile before starting the automobile so as to plan a driving plan and prevent an accident from occurring in the driving process.

Preferably, a wireless receiving module is integrated in the holding part 23 of the mechanical key 2 for receiving external energy through LF to realize wireless charging. Therefore, the power supply of the remote control key is more convenient, and the remote control key can be charged in the driving process only in the charging range of external power supply equipment, such as wireless charging equipment in an automobile, so that the trouble that the shell 1 of the remote control key needs to be opened when a battery is replaced can be avoided.

With the remote control key configured as described above, the mechanical key 2 housed inside the remote control key housing 1 can access the display device 12 provided on the housing 1 as an input device, thereby controlling the automobile. The mechanical key 2 as an input device may control activation or deactivation of the display device 12 through touch sensing. The display device 12 provided on the housing 1 can display various information of the automobile.

It should be noted that the embodiments of the present invention have been described in terms of preferred embodiments, and not by way of limitation, and that those skilled in the art can make modifications and variations of the embodiments described above without departing from the spirit of the invention.
