[0030] With the continuous development of science and technology, smart rings have become an indispensable part of people's lives. Among them, a very convenient function is to use smart rings to operate car keys. The communication components installed in the rings receive and transmit the frequency signals of the car system, allowing users to operate the car key function of the car system through the rings. However, existing smart rings are usually charged through wired chargers. When the rings are in water, the charging port is prone to water ingress, causing the communication components to malfunction, affecting the stability of the car control function.

[0031] The utility model provides a ring-type automobile key, aiming to solve the technical problem of how to improve the functional effect of the ring-type automobile key.

[0032] In the embodiment of the present utility model, Figures 1 to 3 As shown, Figure 1 This is a structural schematic diagram of an embodiment of the ring-type automobile key of the utility model; Figure 2 This is a structural exploded view of an embodiment of the ring-type automobile key of the utility model; Figure 3 It is a structural cross-sectional view of an embodiment of a ring-type automobile key of the utility model.

[0033] The ring-type car key includes: a ring 10, the ring 10 is surrounded by a wearing space 11; a mounting seat 20, the mounting seat 20 is arranged on a side of the ring 10 away from the wearing space 11, and the mounting seat 20 is provided with a mounting cavity 21; a communication module 30, the communication module 30 is installed in the mounting cavity 21, and the communication module 30 is used to communicate with an external communication element; a battery 40, the battery 40 is installed in the mounting cavity 21 and is electrically connected to the communication module 30 to supply power to the communication module 30; a wireless charging receiving unit 50, the wireless charging receiving unit 50 is installed in the mounting cavity 21 and is electrically connected to the battery 40 to charge the battery 40.

[0034] In this embodiment, the ring-type car key can be understood as loading the car control function of the car key into the smart ring, so that the user can control the car by wearing the smart ring on the finger. The ring-type car key can only have the function of controlling the car, or it can also have functions such as near field wireless communication (NFC) and vital sign detection.

[0035] The ring 10 is in a ring shape and is worn on a human finger. The user can put the ring 10 on the finger by passing the finger through the wearing space 11. When the ring-type car key is in the wearing state, the mounting seat 20 is located on the back of the hand. The mounting cavity 21 of the mounting seat 20 can provide an accommodating space for the communication module 30 to hide and protect the communication module 30.

[0036] The communication module 30 is used to realize wireless communication with the car so that the user can control the car through the ring-type car key. There are many forms of communication between the communication module 30 and the vehicle system, such as wireless communication through Bluetooth, 3G network, 4G network or 5G network, which are not limited here.

[0037] For example, the communication module 30 can be a part of a smart key system, a smart key system (PASSIVE KEYLESS ENTER), referred to as PKE, which uses RFID wireless radio frequency technology and a vehicle identity code recognition system, applies a development solution of a miniaturized, low-power radio frequency antenna, integrates a remote control system and a keyless system, and uses traditional vehicle circuit protection to achieve a dual radio frequency system and dual anti-theft protection. In the PKE system, the car serves as a base station and the ring-type car key serves as a transponder to achieve two-way communication. The communication module 30 includes components such as a receiving antenna, a microcontroller, a high-frequency transmitting circuit, a low-frequency receiving circuit, and a control switch.

[0038] Of course, the communication module 30 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 with nanoseconds or less 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 ring-type car key 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, so that users wearing ring-type car keys can automatically control the car without feeling.

[0039] The ring-type car key may further include a circuit board 60 , to which the battery 40 and the communication module 30 are both electrically connected. The battery 40 may provide power to the communication module 30 , and the circuit board 60 is used to transmit control signals to the communication module 30 .

[0040] The wireless charging receiving unit 50 is used to receive an energy signal transmitted by an external wireless charging transmitting module, and convert the energy signal into electric current to transmit to the battery 40, thereby realizing wireless charging of the ring-type car key.

[0041] The wireless charging receiving unit 50 may be an electromagnetic induction receiving unit, a magnetic field resonance receiving unit or a radio wave receiving unit, which is not limited here. Specifically, the wireless charging receiving unit 50 includes an electromagnetic induction receiving coil to receive energy signals through electromagnetic induction phenomenon and convert them into current.

[0042] The wireless charging receiving unit 50 and the communication module 30 may be located on the same side of the circuit board 60 , or may be located on two opposite sides of the circuit board 60 .

[0043] For example, Figure 2 and Figure 3 As shown, the ring-type car key further includes a circuit board 60, the communication module 30 and the battery 40 are mounted on the circuit board 60, the wireless charging receiving unit 50 is electrically connected to the circuit board 60, and the wireless charging receiving unit 50 is located on a side of the circuit board 60 away from the communication module 30. Thus, the heat generated by the wireless charging receiving unit 50 during operation can be prevented from affecting the communication module 30, so as to improve the structural stability of the communication module 30.

[0044] The wireless charging receiving unit 50 may be located on a side of the circuit board 60 facing the wearing space 11 , or may be located on a side of the circuit board 60 facing away from the wearing space 11 .

[0045] Specifically, Figure 2 and Figure 3 As shown, the wireless charging receiving unit 50 is located on the side of the circuit board 60 close to the wearing space 11, and the communication module 30 is located on the side of the circuit board 60 away from the wearing space 11. When the ring-type car key is in the wearing state, the wearing space 11 is penetrated by human fingers. If the communication module 30 is located between the circuit board 60 and the wearing space 11, the signal transmitted / received by the communication module 30 is easily affected by both the human fingers and the circuit board 60, which will cause the signal strength to weaken and affect the vehicle control effect. Therefore, installing the communication module 30 on the side of the circuit board 60 away from the wearing space 11 can ensure the signal strength transmitted / received by the communication module 30 to improve the stability of the vehicle control function. When the ring-type car key is in the charging state, it is usually in the non-wearing state, so the heat generated by the wireless charging receiving unit 50 will not be perceived by the user.

[0046] For example, Figure 2 and Figure 3 As shown, the installation cavity 21 has a first cavity wall close to the wearing space 11, the first cavity wall is convexly provided with a support protrusion 22, the circuit board 60 is abutted against the support protrusion 22, and the wireless charging receiving unit 50 is installed in the first cavity wall and a gap is formed between the circuit board 60. The support protrusion 22 can generate a sufficient distance between the circuit board 60 and the first cavity wall, and the distance is greater than the thickness of the wireless charging receiving unit 50, so as to ensure that a gap is formed between the wireless charging receiving unit 50 installed in the first cavity wall and the circuit board 60. In this way, the wireless charging receiving unit 50 can be prevented from directly contacting the circuit board 60, so as to reduce the influence of the heat generated by the wireless charging receiving unit 50 when working on the circuit board 60, thereby improving the structural stability of the circuit board 60.

[0047] Specifically, Figure 2 and Figure 3As shown, the support protrusion 22 is arranged in an annular shape and surrounds a positioning groove 221, and the circuit board 60 is provided with a positioning boss 61, and the positioning boss 61 cooperates with the positioning groove 221. The positioning boss 61 is fixedly matched with the positioning groove 221, which can prevent the circuit board 60 from shaking or rotating at will in the installation cavity 21, so as to improve the installation stability of the circuit board 60.

[0048] The ring 10 and the mounting seat 20 can be integrally formed, or can be separately formed and then connected together.

[0049] Exemplarily, the ring 10 and the mounting seat 20 are integrally formed, for example, by integral injection molding or integral casting, thereby improving the overall structural strength and connection strength of the ring 10 and the mounting seat 20 and further improving the appearance integrity of the ring type car key.

[0050] Specifically, the mounting cavity 21 has an opening away from the wearing space 11, and the ring-type car key further includes a decorative cover plate 70, which is arranged to cover the opening of the mounting cavity 21, and the communication module 30 is arranged adjacent to the decorative cover plate 70, and the decorative cover plate 70 is a non-metallic cover plate. In the process of processing the ring-type car key, the communication module 30 and other functional components can be installed into the mounting cavity 21 through the opening of the mounting cavity 21, and then the mounting cavity 21 is closed by the decorative cover plate 70, and the decorative cover plate 70 is sealed and connected to the mounting seat 20. The decorative cover plate 70 can also play a decorative role on the ring-type car key to achieve the wearing decorative effect of the ring-type car key.

[0051] In combination with the above-mentioned embodiment in which the ring 10 and the mounting base 20 are integrally formed, the ring 10 and the mounting base 20 can be made of metal material to improve the ability to resist knocks; the decorative cover plate 70 can be a glass plate or a plastic plate. The decorative cover plate 70 is set as a non-metallic cover plate, so that the signal of the communication module 30 can pass through the decorative cover plate 70 to enter and exit the mounting cavity 21, thereby ensuring that the ring-type car key can correctly identify the vehicle signal to improve the control effect of the car.

[0052] In practical applications, such as Figure 1 As shown, the ring 10 is provided with a deformation notch 12, and the deformation notch 12 is opposite to the position of the mounting seat 20. When the user wears the ring-type car key, the ring 10 can be appropriately enlarged through the deformation notch 12 to reduce the wearing difficulty of the user and improve the wearing convenience.

[0053] The utility model also provides an automobile assembly, which includes an automobile and a ring-type automobile key. The specific structure of the ring-type automobile key refers to the above embodiment. Since the automobile assembly adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here. The ring-type automobile key is connected to the automobile for communication.

[0054] In the technical solution of the ring-type car key of the utility model, the signal transmitted and / or received by the communication module 30 can interact with the external vehicle or accessories, so that the ring-type car key can correctly identify the vehicle signal and realize the control of the car. The wireless charging receiving unit 50 can receive the energy signal from the wireless charging transmitting module and convert it into current to charge the battery 40, so as to realize the wireless charging of the ring-type car key. In this way, the charging method of the ring-type car key can be simplified, and the charging port on the surface of the ring-type car key can be omitted to prevent the communication module 30 from malfunctioning due to water entering the charging port, so as to improve the stability of the car control function of the ring-type car key.
