[0031] With the continuous development of technology, intelligent terminals have become an indispensable part of people's lives. Among them, a 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 vehicle system, enabling users to operate the car key function of the vehicle system through the intelligent terminal. In the related art, it is necessary to modify the car circuit before operating the car key function of the vehicle system through the intelligent terminal, which is inconvenient to use.

[0032] The present invention proposes a parking number plate that can be used to control the vehicle, aiming to solve the technical problem of how to improve the convenience of controlling the vehicle by the intelligent terminal.

[0033] In the embodiments of the present invention, as Figure 1 and Figure 4As shown, the parking number plate that can be used to control the car includes: a number plate body 10, and the number plate body 10 is provided with an exposed number mark 11; a communication module 20, and the communication module 20 is installed on the number plate body 10, and the communication module 20 is used to communicate with the vehicle's on-board system and the mobile terminal, so that the mobile terminal can control the car through the communication module 20.

[0034] In this embodiment, the number plate body 10 can be used to display the mobile phone number of the car owner. The specific form of the number plate body 10 is not limited, and it only needs to be provided with an exposed number mark 11. The communication module 20 can be paired with the vehicle system of the car 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, which can be a smart device that the user can carry with him.

[0035] The communication module 20 is used for the user to realize wireless communication with the vehicle system through the mobile terminal, so as to achieve the effect of controlling the locking and unlocking of the vehicle. There are many forms of communication between the communication module 20 and the mobile terminal and the vehicle system, for example, wireless communication can be realized through Bluetooth, 3G network, 4G network or 5G network, etc., which are not limited here.

[0036] For example, the communication module 20 can be a part of the smart key system. The smart key system (PASSIVE KEYLESS ENTER), referred to as PKE, adopts RFID wireless radio frequency technology and vehicle identity coding recognition system, applies the development plan of miniaturization and low-power radio frequency antenna, integrates the remote control system and the keyless system, and adopts the traditional vehicle circuit protection to realize dual radio frequency system and dual anti-theft protection. In the PKE system, the car acts as a base station and the parking number plate acts as a transponder to realize two-way communication. The communication module 20 includes components such as a receiving antenna, a microcontroller, a high-frequency transmitting circuit, a low-frequency receiving circuit, and a control switch.

[0037] Of course, the communication module 20 can also be a component in ultra-wideband wireless carrier communication technology. Ultra-wideband (UltraWide Band) is referred to as UWB, which adopts new ultra-wideband wireless technology that is very different from traditional communication technology. It sends and receives extremely narrow pulses of nanoseconds or below to transmit data to the vehicle, has a bandwidth of 3.1 to 10.6 GHz, and is not easily interfered by other signals. Through the interaction between the UWB of the parking number plate and the UWB of the vehicle, the positioning algorithm characteristics can be used to identify the centimeter-level distance from the vehicle, and a quick response can be easily achieved, allowing the user to automatically control the vehicle through the parking number plate without feeling.

[0038] Install the communication module 20 on the license plate body 10 so that the communication module 20 can communicate with the in-vehicle system in the vicinity, enabling a mobile terminal such as a mobile phone or a smart watch to achieve communication control of the vehicle from outside the vehicle. In this way, when using the parking license plate, only the communication module 20 needs to be paired with the in-vehicle system and the mobile terminal for communication, without the need to modify the in-vehicle wiring or the hardware of the mobile terminal, improving the convenience of vehicle control. Since the position of the parking license plate in the vehicle is relatively stable, the distance between the communication module 20 and the in-vehicle system can be ensured to be relatively stable, thereby ensuring the communication signal strength between the communication module 20 and the in-vehicle system to improve the vehicle control effect.

[0039] The number mark 11 of the license plate body 10 can be switchable or non-switchable.

[0040] Specifically, as Figure 4 and Figure 5 shown, the license plate body 10 includes a housing 12 and a number wheel 13. The housing 12 is provided with a number window 121. The number wheel 13 is rotatably installed in the housing 12. The circumferential wall of the number wheel 13 is adjacent to the number window 121. A plurality of the number marks 11 are distributed on the circumferential wall of the number wheel 13, and each of the number marks can be switchably exposed outside the number window 121. The number of the number wheels 13 is multiple, and the multiple number wheels 13 are arranged along the length direction of the number window 121. The communication module 20 is installed in the housing 12 and is located on the side of the number wheel 13 away from the number window 121.

[0041] Taking a common mobile phone number as an example, the number wheels 13 can be set to 11 to correspond to the 11 digits of the mobile phone number. There are 10 digit marks from 0 to 9 on the circumferential wall of each number wheel 13, and the 10 digit marks are arranged along the circumferential direction of the number wheel 13. By rotating the number wheel 13, each digit mark can be switchably exposed outside the number window 121. By adjusting the exposed digit marks on the 11 number wheels 13, the mobile phone number preset by the user can be arranged. In this way, the user can arbitrarily set the mobile phone number to be displayed through the license plate body 10 to improve the convenience of using the license plate body 10.

[0042] Exemplarily, as Figures 2 to 5As shown, the housing 12 is provided with a first installation cavity 122 and a second installation cavity 123. The digit wheel 13 is installed in the first installation cavity 122. The number window 121 communicates 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 housing 12 is provided with an aromatherapy port 124. The parking number plate further includes an aromatherapy component 30, and the aromatherapy component 30 is installed on the housing 12 and volatilizes aromatherapy gas through the aromatherapy port 124.

[0043] The aromatherapy component 30 houses aromatherapy material, and the aromatherapy material can volatilize aromatherapy gas through the aromatherapy port 124 to improve the smell of the vehicle interior. Combining the aromatherapy component 30 with the number plate body 10 enables the number plate body 10 to have multiple functions such as displaying numbers, controlling the vehicle, and aromatherapy. Since the first installation cavity 122 needs to accommodate a plurality of digit wheels 13 arranged in a straight line, the first installation cavity 122 has a certain length. By arranging the second installation cavity 123 on the side of the first installation cavity 122 away from the number window 121, the shape of the housing 12 can be made more regular, avoiding the length of the parking number plate being much larger than the width, so as to improve the appearance integrity of the parking number plate.

[0044] Specifically, as Figures 2 to 5 shown, the aromatherapy component 30 includes a connection shell 31 and a diffuser 32. The connection shell 31 is fixedly connected to the housing 12. The connection shell 31 has a spice accommodation cavity 311 and a fragrance outlet 312. The fragrance outlet 312 communicates the spice accommodation cavity 311 and the aromatherapy port 124. One end of the diffuser 32 is arranged in the spice accommodation cavity 311, and the other end is arranged in the fragrance outlet 312.

[0045] The spice accommodation cavity 311 is used to accommodate solid spice or liquid spice. One end of the diffuser 32 extends out of the fragrance outlet 312 and is close to the aromatherapy port 124. The diffuser 32 can be a rattan stick or a cotton wick stick. The spice can wet the diffuser 32 and then volatilize and diffuse out of the aromatherapy port 124 through the diffuser 32. By separately providing the connection shell 31 to form the spice accommodation cavity 311, there is no need to form a spice accommodation cavity 311 in the housing 12, which is convenient for replacing the spice and modular assembly of the aromatherapy component 30.

[0046] In practical applications, as Figure 4 and Figure 5As shown, the first installation cavity 122 and the second installation cavity 123 are arranged in sequence in the horizontal direction, and the fragrance receiving cavity 311 and the second installation cavity 123 are arranged correspondingly in the vertical direction. When the fragrance receiving cavity 311 contains fragrance, the overall weight of the aromatherapy assembly 30 is relatively large. Therefore, the fragrance receiving cavity 311 is arranged below the second installation cavity 123 to lower the overall center of gravity of the parking number plate, making the parking number plate more stable in the vehicle and not easy to tip over. The first installation cavity 122 and the second installation cavity 123 are arranged in the horizontal direction, so that the parking number plate can be flat as a whole, which is convenient for observing and turning the number wheel 13.

[0047] For example, Figure 3 and Figure 5 As shown, the bottom wall of the shell 12 is recessed to form a third installation cavity 125, and the fragrance receiving cavity 311 is at least partially received in the third installation cavity 125. The third installation cavity 125 is formed by the bottom wall of the shell 12 being recessed upward, and the fragrance port 124 is opened on the top wall of the shell 12. The connecting shell 31 can be assembled and connected to the bottom of the shell 12 to fully utilize the inner concave space of the shell 12 to receive the adjacent fragrance receiving cavity 311, so that the overall structure of the parking number plate is more compact, the longitudinal space occupied is smaller, and the overall structure is miniaturized.

[0048] For example, Figure 2 and Figure 5 As shown, the connection shell 31 includes a bottom shell 313 and an upper cover 314. The bottom shell 313 includes a bottom plate and a mounting tube disposed in the middle of the bottom plate and having an open upper end. The upper cover 314 is detachably covered on the open portion to enclose the inner wall of the mounting tube to form the fragrance receiving chamber 311; the mounting tube is at least partially received in the third mounting chamber 125; and the periphery of the bottom shell 313 is detachably connected to the housing 12. When the fragrance in the fragrance receiving chamber 311 is completely volatilized, the connection shell 31 can be removed from the housing 12 to separate the fragrance component 30 from the housing 12, and then a new fragrance component 30 can be replaced or fragrance can be added, so that the convenience of replenishing fragrance can be improved. The bottom shell 313 is connected to the housing 12 instead of the mounting tube being connected to the housing 12, which can cover and block the gap between the third mounting chamber 125 and the mounting tube to ensure the appearance consistency of the parking number plate.

[0049] Specifically, Figure 5As shown, the housing 12 includes an upper shell 126 and a lower shell 127 that are detachably connected. The lower shell 127 includes an annular flange and a fixing cylinder connected to the inner peripheral wall of the annular flange and extending away from the upper shell 126. The middle of the bottom wall of the fixing cylinder is recessed to form the installation cavity. An embedding cavity is formed by enclosing the outer peripheral wall of the bottom shell 313 and the installation cylinder, 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-fold stepped 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 an embedded structure, expanding the accommodation space and making the overall structure more compact.

[0050] Exemplarily, as Figure 4 and Figure 5 shown, the parking number plate that can be used to control the vehicle further includes a circuit board 40, a battery 41 electrically connected to the circuit board 40, and a heating element 42. The circuit board 40 is electrically connected to the communication module 20. The circuit board 40 and the battery 41 are installed in the second installation cavity 123. One end of the aroma diffuser 32 extends into the second installation cavity 123, and the heating element 42 is used to heat the aroma diffuser 32. The battery 41 can provide electrical energy for the heating element 42 and the communication module 20, and the circuit board 40 can transmit electrical energy and control signals for the communication module 20 and the heating element 42. The heating element 42 can heat the aroma diffuser 32 to increase the volatilization rate of the fragrance by the aroma diffuser 32, thereby improving the aromatherapy effect. By controlling the heating power of the heating element 42, the temperature of the aroma diffuser 32 can be controlled, and further the volatilization speed of the fragrance can be controlled. Therefore, a button can be provided at the top of the housing 12. The button is electrically connected to the circuit board 40, and the user can control the volatilization rate of the fragrance through the button.

[0051] Specifically, as Figure 4 and Figure 5 shown, the first installation cavity 122 is arranged in a long strip shape, and the second installation cavity 123 is arranged in a circular shape. And at least the outer peripheral wall of the connecting shell 31 is spliced with the outer peripheral wall of the housing 12 that encloses the second installation cavity 123. The long-strip-shaped first installation cavity 122 is convenient for placing the number plate, and the circular second installation cavity 123 is spliced with the circular connecting shell 31 to ensure the overall appearance consistency.

[0052] Exemplarily, the parking number plate that can be used to control the vehicle further includes a wireless networking module (not shown in the figure). The wireless networking module is installed on the number plate body and is used to enable a mobile device to connect to the wireless network. The wireless networking module is a Wi-Fi module that can emit radio waves for mobile devices such as smartphones, tablets, and smartwatches to connect to the network. Combining with the above embodiment of the circuit board 40, the wireless networking module can be installed on the circuit board 40. Installing the wireless networking module in the parking number plate that can be used to control the vehicle can endow the parking number plate with the function of a wireless router, improving the usage effect of the parking number plate.

[0053] Specifically, the parking number plate that can be used to control the vehicle further includes a solar photovoltaic panel 50 installed on the top wall of the connection shell 31. A through hole is provided on the top wall of the connection shell 31, and the solar photovoltaic panel 50 is electrically connected to the circuit board 40 through the through hole. The solar photovoltaic panel 50 is a power generation device that generates direct current when exposed to sunlight and is composed of thin solid photovoltaic cells made almost entirely of semiconductor materials (such as silicon). The solar photovoltaic panel 50 can be electrically connected to the charging circuit on the circuit board 40 through a conductive sheet. The parking number plate is placed on the center console near the windshield inside the vehicle. Therefore, the solar photovoltaic panel 50 can be exposed to the sunlight irradiating on the center console, so as to use solar energy to charge the battery 41 and 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 by solar energy to improve the charging convenience of the parking number plate.

[0054] Exemplarily, as Figure 6 shown, the parking number plate that can be used to control the vehicle further includes 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 to the movable cover plate 15 to drive the movable cover plate 15 to move; the circuit board 40 is electrically connected to the driving device to control the driving device to drive the movable cover plate 15 after receiving a control signal.

[0055] When the user locks the car through the smart terminal and the parking number plate, the circuit board 40 not only controls the communication module 20 to lock the car, but also controls the driving device to drive the movable cover plate 15 to open the number window 121 and expose the number mark 11, so that the user can simultaneously lock the car and expose the number mark 11 through one operation step. Similarly, when the user unlocks the car through the smart terminal and the parking number plate, the circuit board 40 not only controls the communication module 20 to unlock the car, but also controls the driving device to drive the movable cover plate 15 to close the number window 121 and cover the number mark 11, so that the user can simultaneously unlock the car and cover the number mark 11 through one operation step.

[0056] The above are only alternative embodiments of the present utility model, and do not thus limit the patent scope of the present utility model. Any equivalent structural transformation made under the inventive concept of the present utility model by using the content of the specification and drawings of the present utility model, or any direct / indirect application in other related technical fields, is included within the patent protection scope of the present utility model.
