[0033] With the continuous development of science and technology, intelligent terminals have become an indispensable part of people's lives. One very convenient function is to operate the car key through the intelligent terminal. The communication element installed in the intelligent terminal receives and transmits the frequency signal of the car machine system, so that the user can operate the car key function of the car machine system through the intelligent terminal. In related technologies, before operating the car key function of the car machine system through the intelligent terminal, the automobile circuit needs to be modified, which is inconvenient to use.

[0034] The present application provides a parking number plate that can be used to control a car, aiming to solve the technical problem of how to improve the convenience of intelligent terminal control of a car.

[0035] In the embodiments of the present application, as shown in FIG. 1 and FIG. 4, the parking number plate capable of controlling the vehicle includes: a number plate body 10 provided with an exposed number sign 11; and a communication module 20 installed on the number plate body 10, which is used to communicate with the vehicle machine system and the mobile terminal, so that the mobile terminal controls the vehicle through the communication module 20.

[0036] In the embodiments, the number plate body 10 can be used to display the mobile phone number of the vehicle owner, and the specific form of the number plate body 10 is not limited as long as it is provided with the exposed number sign 11. The communication module 20 can be paired with the vehicle machine system and the user's mobile terminal for communication. The mobile terminal is a smart terminal, such as a mobile phone, a smart watch, or a smart bracelet, and the like, which can be carried by the user.

[0037] The communication module 20 is used for the user to realize wireless communication with the vehicle machine system through the mobile terminal, so as to achieve the effect of controlling the vehicle to lock or unlock. The communication form between the communication module 20 and the mobile terminal and the vehicle machine system is not limited, for example, the wireless communication can be realized through Bluetooth, 3G network, 4G network or 5G network, and the like.

[0038] For example, the communication module 20 can be part of a smart key system (PASSIVE KEYLESS ENTER, PKE for short), which adopts RFID wireless radio frequency technology and vehicle identity coding identification system, applies a development scheme of small-sized and low-power radio frequency antenna, and combines the remote control system and the keyless system, and follows the traditional vehicle circuit protection to realize double radio frequency systems and double anti-theft protection. In the PKE system, the vehicle acts as a base station, and the parking number plate acts as a transponder to realize two-way communication. The communication module 20 includes a receiving antenna, a microcontroller, a high-frequency transmitting circuit, a low-frequency receiving circuit, and a control switch, and the like.

[0039] Of course, the communication module 20 can also be an element in the ultra-wideband wireless carrier communication technology. Ultra-wideband (Ultra Wide Band, UWB for short) adopts a new ultra-wideband wireless technology which is greatly different from traditional communication technologies. The transmission and reception of extremely narrow pulses with nanoseconds or below nanoseconds level are used to transmit data with vehicles, which has a bandwidth of 3.1-10.6 GHz level and is not easy to be disturbed by other signals. Through the interaction between the UWB of the parking number plate and the UWB of the vehicle, the positioning algorithm feature can be used to identify the centimeter-level distance from the vehicle, so that the user can automatically control the vehicle through the parking number plate without feeling.

[0040] The communication module 20 is installed on the number plate body 10, so that the communication module 20 can be connected with the vehicle machine system in proximity, so that the mobile terminal such as a mobile phone or a smart watch can realize communication control of the vehicle through the communication module 20 from outside the vehicle. In this way, when using the parking number plate, the communication module 20 only needs to be paired with the vehicle machine system and the mobile terminal, without the need to modify the vehicle machine circuit and without the need to modify the hardware of the mobile terminal, thereby improving the convenience of vehicle control. Since the position of the parking number plate in the vehicle is relatively stable, the distance between the communication module 20 and the vehicle machine system can be relatively stable, thereby ensuring the communication signal strength between the communication module 20 and the vehicle machine system, so as to improve the effect of vehicle control.

[0041] The number signs 11 of the number plate body 10 can be switchable or non-switchable.

[0042] Specifically, as shown in FIGS. 4 and 5, the number plate body 10 includes a shell 12 and a number wheel 13, the shell 12 is provided with a number window 121, the number wheel 13 is rotatably installed in the shell 12, the peripheral wall of the number wheel 13 is adjacent to the number window 121, and the peripheral wall of the number wheel 13 is provided with a plurality of number signs 11, each number sign 11 is switchably exposed to the number window 121, the number wheel 13 is in plurality, and a plurality of number wheels 13 are arranged along the length direction of the number window 121; the communication module 20 is installed in the shell 12 and located on the side of the number wheel 13 away from the number window 121.

[0043] Taking a common mobile phone number as an example, the number wheel 13 can be provided with 11 number wheels to correspond to 11 digits of the mobile phone number. The peripheral wall of each number wheel 13 is provided with 10 number signs from 0 to 9, and the 10 number signs are arranged along the circumferential direction of the number wheel 13. By rotating the number wheel 13, each number sign can be switchably exposed to the number window 121. By adjusting the exposed number signs on the 11 number wheels 13, the user's preset mobile phone number can be arranged. In this way, the user can arbitrarily set the mobile phone number to be displayed through the number plate body 10, thereby improving the use convenience of the number plate body 10.

[0044] For example, as shown in FIGS. 2 to 5, the shell 12 is provided with a first installation cavity 122 and a second installation cavity 123, the number wheel 13 is installed in the first installation cavity 122, the number window 121 is communicated with the first installation cavity 122, the second installation cavity 123 is located on the side of the first installation cavity 122 away from the number window 121, and the communication module 20 is installed in the second installation cavity 123; the shell 12 is provided with a fragrance port 124, and the parking number plate further includes a fragrance assembly 30, the fragrance assembly 30 is installed in the shell 12 and volatilizes fragrance gas through the fragrance port 124.

[0045] The aromatherapy component 30 contains aromatherapy materials, which can volatilize aromatic gas through the aromatherapy port 124 to improve the odor of the vehicle interior. The combination of the aromatherapy component 30 and the number plate body 10 enables the number plate body 10 to have multiple functions such as displaying numbers, controlling vehicles, and aromatherapy. Since the first mounting cavity 122 needs to accommodate multiple number wheels 13 arranged in a straight line, the first mounting cavity 122 has a certain length, and the second mounting cavity 123 is arranged on the side of the first mounting cavity 122 away from the number window 121, which can make the shape of the shell 12 more regular, avoid the length of the parking number plate being much larger than the width, and improve the appearance integrity of the parking number plate.

[0046] Specifically, as shown in FIGS. 2-5, the aromatherapy component 30 includes a connecting shell 31 and an aroma-expanding piece 32. The connecting shell 31 is fixedly connected to the shell 12, and has an aroma-containing cavity 311 and an aroma-dispensing port 312 inside. The aroma-dispensing port 312 is in communication with the aroma-containing cavity 311 and the aromatherapy port 124. One end of the aroma-expanding piece 32 is arranged in the aroma-containing cavity 311, and the other end is arranged in the aroma-dispensing port 312.

[0047] The aroma-containing cavity 311 is used to accommodate solid or liquid aromatherapy materials. One end of the aroma-expanding piece 32 extends out of the aroma-dispensing port 312 and is close to the aromatherapy port 124. The aroma-expanding piece 32 can be a rattan stick or a cotton core stick. The aroma-expanding piece 32 can be soaked with aromatherapy materials and then volatilize and diffuse the aromatherapy materials outside the aromatherapy port 124. By separately arranging the connecting shell 31 to form the aroma-containing cavity 311, it is not necessary to form the aroma-containing cavity 311 in the shell 12, which facilitates the replacement of the aromatherapy materials and the modular assembly of the aromatherapy component 30.

[0048] In actual application, as shown in FIGS. 4 and 5, the first mounting cavity 122 and the second mounting cavity 123 are arranged in sequence in the transverse direction, and the aroma-containing cavity 311 is arranged in correspondence with the second mounting cavity 123 in the longitudinal direction. When the aroma-containing cavity 311 contains aromatherapy materials, the overall weight of the aromatherapy component 30 is relatively large. Therefore, arranging the aroma-containing cavity 311 below the second mounting cavity 123 can lower the overall center of gravity of the parking number plate, making the parking number plate more stable when placed in the vehicle and less likely to tip over. Arranging the first mounting cavity 122 and the second mounting cavity 123 in the transverse direction enables the parking number plate as a whole to have a flat structure, which facilitates the observation and manipulation of the number wheels 13.

[0049] As shown in FIG. 3 and FIG. 5, the bottom wall of the shell 12 is concave to form a third installation cavity 125, and the fragrance accommodating cavity 311 is at least partially accommodated in the third installation cavity 125. The third installation cavity 125 is concave upward from the bottom wall of the shell 12, and the incense opening 124 is formed in the top wall of the shell 12. The connecting shell 31 can be assembled to the lower part of the shell 12 to make full use of the concave space of the shell 12 to accommodate the adjacent fragrance accommodating cavity 311, so that the overall structure of the parking sign is more compact and occupies less vertical space, realizing the miniaturization of the overall structure.

[0050] As shown in FIG. 2 and FIG. 5, the connecting shell 31 includes a bottom shell 313 and an upper cover 314. The bottom shell 313 includes a bottom plate and an installation cylinder provided in the middle of the bottom plate and open at the upper end. The upper cover 314 is detachably covered on the opening to form the fragrance accommodating cavity 311 with the inner wall of the installation cylinder. The installation cylinder is at least partially accommodated in the third installation cavity 125. The periphery of the bottom shell 313 is detachably connected to the shell 12. When the fragrance in the fragrance accommodating cavity 311 is volatilized, the connecting shell 31 can be detached from the shell 12 to separate the incense assembly 30 from the shell 12, and then a new incense assembly 30 or fragrance can be added. In this way, the convenience of replenishing the fragrance can be improved. The connection of the bottom shell 313 and the shell 12 instead of the installation cylinder and the shell 12 can cover and shield the gap between the third installation cavity 125 and the installation cylinder, ensuring the appearance consistency of the parking sign.

[0051] Specifically, as shown in FIG. 5, the shell 12 includes a detachably connected upper shell 126 and a lower shell 127. The lower shell 127 includes an annular flange, a fixing cylinder connected to the inner peripheral wall of the annular flange and extending away from the upper shell 126, and a bottom wall of the fixing cylinder is concave in the middle to form the installation cavity. The bottom shell 313 and the outer peripheral wall of the installation cylinder form an embedding cavity, and the fixing cylinder is embedded in the embedding cavity. The annular flange, the fixing cylinder and the third installation cavity 125 form a three-step structure. The fixing cylinder is embedded in the embedding cavity, and the installation cylinder is accommodated in the third installation cavity 125, so that the lower shell 127 and the connecting shell 31 form a nested structure, which expands the accommodation space while making the overall structure more compact.

[0052] As shown in FIGS. 4 and 5, the parking number plate for controlling vehicle further comprises a circuit board 40, a battery 41 and a heating element 42, the circuit board 40 is electrically connected with the communication module 20, the circuit board 40 and the battery 41 are installed in the second installation cavity 123, one end of the fragrance diffusing element 32 extends into the second installation cavity 123, and the heating element 42 is used for heating the fragrance diffusing element 32. The battery 41 can provide power for the heating element 42 and the communication module 20, and the circuit board 40 can transmit power and control signals for the communication module 20 and the heating element 42. The heating element 42 can heat the fragrance diffusing element 32 to improve the evaporation rate of the fragrance diffusing element 32 to the fragrance, thereby improving the aromatherapy effect. By controlling the heating power of the heating element 42, the temperature of the fragrance diffusing element 32 can be controlled, and then the evaporation rate of the fragrance can be controlled. Therefore, the top of the shell 12 can be provided with a button, the button is electrically connected with the circuit board 40, and the user can control the evaporation rate of the fragrance through the button.

[0053] Specifically, as shown in FIGS. 4 and 5, the first installation cavity 122 is in a strip shape, and the second installation cavity 123 is in a circular shape. The outer peripheral wall of the connecting shell 31 is spliced with the outer peripheral wall of the shell 12 to form the second installation cavity 123. The strip-shaped first installation cavity 122 facilitates the placement of the number plate, and the circular second installation cavity 123 is spliced with the circular connecting shell 31 to ensure the consistency of the overall appearance.

[0054] As shown in FIGS. 4 and 5, the parking number plate for controlling vehicle further comprises a wireless networking module (not shown in the drawings), which is installed in the number plate body and used for wireless networking of mobile devices. The wireless networking module, i.e., the Wi-Fi module, can emit radio waves for mobile devices such as smartphones, tablets and smartwatches to connect to the network. In combination with the above-mentioned embodiment of the circuit board 40, the wireless networking module can be installed in the circuit board 40. By installing the wireless networking module in the parking number plate for controlling vehicle, the parking number plate can have the function of a wireless router, thereby improving the use effect of the parking number plate.

[0055] Specifically, the parking number plate capable of controlling the vehicle further comprises a solar photovoltaic panel 50 installed on the top wall of the connecting shell 31, and the top wall of the connecting shell 31 is provided with a through hole, and the solar photovoltaic panel 50 is electrically connected with the circuit board 40 through the through hole. The solar photovoltaic panel 50 is a power generation device that can generate direct current when exposed to sunlight, and is composed of a thin solid photovoltaic cell made of almost all semiconductor materials (such as silicon). The solar photovoltaic panel 50 can be electrically connected with the charging circuit on the circuit board 40 through a conductive sheet. The parking number plate is placed on the center console close to the windshield in the vehicle, so the solar photovoltaic panel 50 can be exposed to the sunlight irradiating on the center console, thereby charging the battery 41 with solar energy to save the electricity cost. After the user parks the vehicle at a fixed position and leaves the vehicle, the parking number plate placed on the center console can be autonomously charged with solar energy, thereby improving the charging convenience of the parking number plate.

[0056] For example, as shown in FIG. 6, the parking number plate capable of controlling the vehicle further comprises a movable cover plate 15, a driving device, and a circuit board 40. The movable cover plate 15 is rotatably installed at the number window 121 to cover or expose the number mark 11. The output shaft of the driving device is connected with the movable cover plate 15 to drive the movable cover plate 15 to move. The circuit board 40 is electrically connected with the driving device to control the driving device to drive the movable cover plate 15 after receiving a control signal.

[0057] When the user locks the vehicle through the intelligent terminal and the parking number plate, the circuit board 40 controls the communication module 20 to lock the vehicle and controls the driving device to drive the movable cover plate 15 to open the number window 121 to expose the number mark 11, so that the user can realize locking the vehicle and exposing the number mark 11 at the same time through one operation step. Similarly, when the user unlocks the vehicle through the intelligent terminal and the parking number plate, the circuit board 40 controls the communication module 20 to unlock the vehicle and controls the driving device to drive the movable cover plate 15 to close the number window 121 to cover the number mark 11, so that the user can realize unlocking the vehicle and covering the number mark 11 at the same time through one operation step.

[0058] The application further provides a parking number plate capable of controlling a vehicle, which aims to solve the technical problem of how to improve the convenience of controlling the vehicle by using an intelligent terminal.

[0059] In the embodiment of the application, as shown in FIG. 7 and FIG. 9, the parking number plate capable of controlling the vehicle comprises a number plate body 10, wherein the surface of the number plate body 10 is provided with a display screen 11 for displaying a number; and a communication module 20 installed on the number plate body 10, which is used to communicate with the vehicle infotainment system and a mobile terminal, so that the mobile terminal can control the vehicle through the communication module 20.

[0060] In the embodiment, the number plate body 10 can display the mobile phone number of the vehicle owner through the display screen 11, and the communication module 20 can communicate with the vehicle machine system and the mobile terminal of the user. The mobile terminal is a smart terminal, for example, a mobile phone, a smart watch, a smart bracelet or other smart devices that can be carried by the user.

[0061] The communication module 20 is used for the user to realize wireless communication between the mobile terminal and the vehicle machine system, so as to achieve the effect of controlling the vehicle to lock or unlock. The communication form between the communication module 20 and the mobile terminal and the vehicle machine system can be various, for example, the wireless communication can be realized through Bluetooth, 3G network, 4G network or 5G network, which is not limited here.

[0062] For example, the communication module 20 can be part of a smart key system (PASSIVE KEYLESS ENTER, PKE for short), which adopts RFID wireless radio frequency technology and vehicle identity coding identification system, applies the development scheme of small-sized and low-power radio frequency antenna, and combines remote control system and keyless system, and follows the traditional vehicle circuit protection, realizes double radio frequency system and double anti-theft protection. In the PKE system, the vehicle acts as a base station, and the parking number plate acts as a transponder to realize two-way communication. The communication module 20 includes receiving antenna, microcontroller, high-frequency transmitting circuit, low-frequency receiving circuit and control switch and other elements.

[0063] Of course, the communication module 20 can also be an element in the ultra-wideband wireless carrier communication technology. Ultra-wideband (Ultra Wide Band, UWB for short) adopts a new ultra-wideband wireless technology which is greatly different from traditional communication technology. The transmission and reception of extremely narrow pulses with nanoseconds or below nanoseconds transmits data with vehicles, has a bandwidth of 3.1-10.6GHz, and is not easy to be disturbed by other signals. Through the interaction between the UWB of the parking number plate and the UWB of the vehicle, the characteristics of the positioning algorithm can identify the distance of centimeter level with the vehicle, easily achieve fast response, and make the user automatically control the vehicle through the parking number plate without feeling.

[0064] The communication module 20 is installed on the number plate body 10, so that the communication module 20 can be connected with the vehicle machine system in proximity, so that the mobile terminal such as mobile phone or smart watch can realize communication control of the vehicle through the communication module 20 from outside the vehicle. In this way, when using the parking number plate, the communication module 20 only needs to be paired with the vehicle machine system and the mobile terminal, without the need to modify the vehicle machine circuit and the hardware of the mobile terminal, thereby improving the convenience of vehicle control. Since the position of the parking number plate in the vehicle is relatively stable, the distance between the communication module 20 and the vehicle machine system can be relatively stable, thereby ensuring the communication signal strength between the communication module 20 and the vehicle machine system, and improving the effect of vehicle control.

[0065] Specifically, as shown in FIG. 7 and FIG. 8, the number plate body 10 comprises a shell 12, the shell 12 is provided with a display window, the display screen 11 is installed in the display window, the parking number plate further comprises a circuit board 40 installed in the shell 12, the communication module 20 is installed on the circuit board 40, the circuit board 40 is electrically connected with the display screen 11, and the communication module 20 is also used for the mobile terminal to control the display screen 11 to display, hide or change the number.

[0066] The circuit board 40 is used to distribute electric energy to the communication module 20 and the display screen 11 and transmit control signals. The display screen 11 can be a light emitting diode display screen 11. When the user locks the car through the intelligent terminal and the parking number plate, the circuit board 40 controls the communication module 20 to lock the car and controls the display screen 11 to display the number, so that the user can realize locking the car and displaying the number through one operation step.
