[0034] With the continuous development of science and technology, intelligent rings have become an indispensable part of people's lives. One very convenient function is to operate the car key through the intelligent ring. The communication element installed in the ring receives and transmits the frequency signal of the car system, so that the user can operate the car key function of the car system through the ring. However, the existing intelligent ring usually controls the communication element through a mechanical button. The waterproof performance of the mechanical button is poor, the service life is short, and the communication element is prone to malfunction, affecting the stability of the car control function.

[0035] The present application provides a ring type car key, which aims to solve the technical problem of how to improve the stability of the car control function of the ring type car key.

[0036] In the embodiment of the present application, as shown in FIGS. 1-3, FIG. 1 is a structural schematic diagram of an embodiment of the ring type car key of the present application; FIG. 2 is a structural exploded view of an embodiment of the ring type car key of the present application; and FIG. 3 is a structural sectional view of an embodiment of the ring type car key of the present application.

[0037] The ring type car key comprises a ring 10, the ring 10 is provided with a wearing space 11; a mounting seat 20, the mounting seat 20 is arranged on the side of the ring 10 away from the wearing space 11, the mounting seat 20 is provided with a mounting cavity 21 and a button hole 22 communicating with the 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 external elements; a touch button 40, the touch button 40 is installed on the mounting seat 20 and electrically connected with the communication module 30 through the button hole 22, and the touch button 40 is used to control the communication module 30 to open or close.

[0038] In the embodiment, the ring type car key can be understood as loading the car control function of the car key in the intelligent ring, so that the user can control the car through the intelligent ring worn on the finger. The ring type car key can only have the function of controlling the car, or can also have the functions of near field communication (NFC) and vital sign detection.

[0039] The ring 10 is annular, used for wearing on the human finger, and the user can wear the ring 10 on the finger by putting 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 a containing space for the communication module 30, so as to hide and protect the communication module 30.

[0040] The communication module 30 is used to realize wireless communication with the automobile, so that the user can control the automobile through the ring-shaped automobile key. The communication module 30 can communicate with the vehicle system in many forms, such as through Bluetooth, 3G network, 4G network or 5G network, etc., which is not limited here.

[0041] For example, the communication module 30 can be part of a smart key system, a passive keyless entry (PKE) system, which uses RFID wireless radio frequency technology and a vehicle identity coding identification system, applies a development scheme of a small-sized and low-power radio frequency antenna, and combines a remote control system and a keyless system, and follows the traditional whole vehicle circuit protection to realize a double radio frequency system and double anti-theft protection. In the PKE system, the automobile is used as a base station, and the ring-shaped automobile key is used as a transponder to realize bidirectional communication. The communication module 30 includes a receiving antenna, a microcontroller, a high-frequency transmitting circuit, a low-frequency receiving circuit, and a control switch and other elements.

[0042] Of course, the communication module 30 can also be an element in the ultra-wideband wireless carrier communication technology. Ultra-wideband (UWB) is a new wireless technology that is very different from traditional communication technology. The transmission and reception of extremely narrow pulses with nanoseconds or less than nanoseconds are used to transmit data to vehicles, with a bandwidth of 3.1-10.6 GHz, which is not easily disturbed by other signals. Through the UWB interaction between the ring-shaped automobile key and the vehicle UWB, the positioning algorithm feature can identify the centimeter-level distance from the vehicle, and easily achieve fast response, so that the user wearing the ring-shaped automobile key can automatically control the vehicle without feeling.

[0043] The ring-shaped automobile key can also include a battery 70 and a circuit board 60, and the communication module 30 and the battery 70 are installed on the circuit board 60. The battery 70 can provide power for the communication module 30, and the circuit board 60 is used to transmit control signals to the communication module 30.

[0044] The trigger switch is arranged in the installation cavity 21 close to the keyhole 22, and the trigger switch is electrically connected to the circuit board 60 and the touch key 40. When the touch key 40 generates a control signal, the trigger switch can trigger the communication module 30 to turn on or off. The touch key 40 can be one of a capacitive touch key 40, a resistive touch key 40, an infrared touch key 40, or a surface acoustic wave touch key 40.

[0045] The touch button 40 and the button hole 22 can be sealed by sealing glue or by a sealing ring, which is not limited herein. The touch button 40 generates a control signal without a movement stroke, so that a movement gap is not required between the touch button 40 and the mounting seat 20, which is easier to seal and has better waterproof performance. Since the ring-type automobile key is worn on the user's finger, it is more likely to be involved in water during the user's daily activities. Therefore, by arranging the touch button 40, the external water can be effectively prevented from entering the mounting cavity 21 to cause the communication module 30 to malfunction, so as to ensure the functional stability of the ring-type automobile key.

[0046] The touch button 40 is mounted on the outer wall surface of the mounting seat 20, which can protrude from the outer wall surface of the mounting seat 20 or be embedded in the outer wall surface of the mounting seat 20, which is not limited herein.

[0047] Specifically, as shown in FIGS. 2 and 3, the outer wall surface of the mounting seat 20 is provided with a button groove 23, the button hole 22 is arranged at the groove bottom of the button groove 23, and the touch button 40 is mounted on the button groove 23. In this way, the cooperation area of the touch button 40 and the mounting seat 20 can be increased, the installation stability can be improved, and the touch button 40 can be protected. The touch surface of the touch button 40 can be flush with the groove opening of the button groove 23, so that the appearance integrity of the ring-type automobile key can be improved.

[0048] The touch button 40 can be located on one side in the thickness direction of the ring 10 or on the circumferential side of the ring 10, which is not limited herein.

[0049] Specifically, as shown in FIGS. 1 to 3, the mounting seat 20 has a first side wall 24 located on the circumferential side of the ring, and the touch button 40 is mounted on the first side wall 24. In this way, the touch button 40 can be located on the circumferential side of the ring 10, and when the ring-type automobile key is in a wearing state, the touch button 40 is located on the left and right sides of the finger wearing the ring-type automobile key, so that the user can more easily touch the touch button 40 when needed to control, thereby improving the user's convenience.

[0050] The number of the touch button 40 can be one, two or more, which is not limited herein.

[0051] Specifically, as shown in FIG. 2 and FIG. 3, the mounting base 20 further has a second side wall 25 opposite to the first side wall 24, and the first side wall 24 and the second side wall 25 are both provided with the key hole 22, and the number of the touch keys 40 is two, and the two touch keys 40 are respectively installed on the first side wall 24 and the second side wall 25. When the ring type automobile key is in the wearing state, the two touch keys 40 are respectively located at the left and right sides of the fingers wearing the ring type automobile key, and the user can control the communication module 30 to be turned on by touching one of the touch keys 40, and then control the communication module 30 to be turned off by touching the other touch key 40.

[0052] In actual application, as shown in FIG. 2 and FIG. 3, the first side wall 24 and the second side wall 25 are smoothly connected with the outer circumferential wall of the ring 10, so that the appearance integrity of the ring type automobile key can be improved.

[0053] Specifically, as shown in FIG. 2 and FIG. 3, the mounting cavity 21 has an opening facing away from the wearing space 11, and the ring type automobile key further comprises a decorative cover plate 50, and the decorative cover plate 50 covers the opening of the mounting cavity 21. In the process of processing the ring type automobile key, the functional elements such as the communication module 30 can be loaded 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 50, and the decorative cover plate 50 is sealingly connected with the mounting base 20. The decorative cover plate 50 can also play a decorative role for the ring type automobile key, so as to realize the wearing and decorative effect of the ring type automobile key.

[0054] Specifically, the decorative cover plate 50 is configured as a knocking sensing element and is electrically connected with the communication module 30, and the decorative cover plate 50 is used to control the communication module 30 to be turned on or turned off when receiving a preset knocking instruction. The knocking sensing element is a vibration transmission element, and the knocking sensing element is configured to generate a control signal when receiving a preset knocking instruction. For example, the decorative cover plate 50 can be configured to generate an opening signal to control the communication module 30 to be turned on when being knocked twice in succession, and generate a closing signal to control the communication module 30 to be turned off when being knocked three times in succession. In this way, the way for the user to control the vehicle through the ring type automobile key can be increased, and the use convenience of the user can be further improved.

[0055] In practical application, the ring 10 and the mounting base 20 are integrally formed, so that the overall structural strength and connection strength of the ring 10 and the mounting base 20 are improved, and the appearance integrity of the ring-shaped automobile key is further improved. In combination with the above-mentioned embodiment of the decorative cover plate 50, the ring 10 and the mounting base 20 can be made of metal material to improve the anti-impact ability; the decorative cover plate 50 is provided as a non-metal cover plate, such as a glass plate or a plastic plate, so that the signals of the communication module 30 pass in and out of the mounting cavity 21 through the decorative cover plate 50, and the ring-shaped automobile key can correctly identify the vehicle signals, so as to improve the control effect on the automobile.

[0056] For example, as shown in FIGS. 1-3, the ring 10 is provided with a deformation gap 12 opposite to the position where the mounting base 20 is located. When the user wears the ring-shaped automobile key, the ring 10 can be appropriately expanded through the deformation gap 12, so as to reduce the wearing difficulty of the user and improve the wearing convenience.

[0057] The present application also provides a ring-shaped automobile key, which aims to solve the technical problem of how to improve the functional effect of the ring-shaped automobile key.

[0058] In the embodiment of the present application, as shown in FIGS. 4-6, FIG. 4 is a structural schematic view of an embodiment of the ring-shaped automobile key of the present application; FIG. 5 is a structural schematic view of another embodiment of the ring-shaped automobile key of the present application; and FIG. 6 is a structural sectional view of an embodiment of the ring-shaped automobile key of the present application.

[0059] The ring-shaped automobile key comprises: a ring 10, which is provided with a wearing space 11; a mounting base 20, which is arranged on the side of the ring 10 away from the wearing space 11, and is provided with a mounting cavity 21; a communication module 30, which is installed in the mounting cavity 21, and is used to communicate with external elements; and a vital sign monitoring module 40, which is installed in the mounting base 20 or the ring 10, and is at least partially exposed to the wearing space 11.

[0060] In the embodiment, the ring-shaped automobile key can be understood as loading the vehicle control function of the automobile key in the smart ring, so that the user can control the automobile through the smart ring worn on the finger. The ring-shaped automobile key can only have the function of controlling the automobile, or can also have the functions of near field communication (NFC) and vital sign detection.

[0061] The ring 10 is annular, and is used for wearing on a human finger. A user can put the finger through the wearing space 11 to wear the ring 10 on the finger. When the ring-type automobile key is in a wearing state, the mounting seat 20 is located on the back side of the hand. The mounting cavity 21 of the mounting seat 20 can provide a containing space for the communication module 30, so as to play a hiding and protecting role on the communication module 30.

[0062] The communication module 30 is used to realize wireless communication with the automobile, so that the user can control the automobile through the ring-type automobile key. The communication form of the communication module 30 with the vehicle system is various, for example, wireless communication can be realized through Bluetooth, 3G network, 4G network or 5G network, etc., which is not limited here.

[0063] For example, the communication module 30 can be part of a smart key system, a passive keyless entry (PKE) system, which uses RFID wireless radio frequency technology and vehicle identity coding identification system, and applies a development scheme of a small-sized and low-power radio frequency antenna, and combines a remote control system and a keyless system, and follows a traditional whole vehicle circuit protection, realizes a double radio frequency system, and double anti-theft protection. In the PKE system, the automobile is used as a base station, and the ring-type automobile key is used as a transponder to realize bidirectional communication. The communication module 30 includes a receiving antenna, a microcontroller, a high-frequency transmitting circuit, a low-frequency receiving circuit, and a control switch and other elements.

[0064] Of course, the communication module 30 can also be an element in the ultra-wideband wireless carrier communication technology. Ultra-wideband (UWB) is a new wireless technology that 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 3.1-10.6 GHz, and is not easily disturbed by other signals. Through the UWB of the ring-type automobile key and the UWB of the vehicle, the characteristics of the positioning algorithm can be used to identify the centimeter-level distance from the vehicle, and quickly respond, so that the user wearing the ring-type automobile key can automatically control the vehicle without feeling.

[0065] The ring-type automobile key can also include a battery 70 and a circuit board 50, and the communication module 30 and the battery 70 are installed on the circuit board 50. The battery 70 can provide power for the communication module 30, and the circuit board 50 is used to transmit control signals to the communication module 30.

[0066] The vital sign monitoring module 40 is used to monitor the vital sign parameters of the human body, for example, at least one of the body temperature, blood oxygen, heart rate and blood pressure of the human body. The vital sign monitoring module 40 is at least partially exposed to the wearing space 11, so that after the user wears the ring-type automobile key, the vital sign monitoring module 40 can be in contact with the skin of the user's finger to monitor the vital sign parameters of the wearer.

[0067] The monitoring result of the vital sign monitoring module 40 can be displayed through a display component installed on the mounting base 20, played through a playing component installed on the mounting base 20, or transmitted to a mobile device of the user through the communication module 30 for reading by the user, without limitation.

[0068] Specifically, as shown in FIG. 6, the inner peripheral wall of the ring 10 is provided with a mounting groove 12, and the vital sign monitoring module 40 is installed in the mounting groove 12. The mounting groove 12 can increase the cooperation area of the vital sign monitoring module 40 and the ring 10, so as to improve the installation stability of the vital sign monitoring module 40. The contact surface of the vital sign monitoring module 40 can be flush with the groove of the mounting groove 12, so as to improve the appearance integrity of the ring type automobile key and the wearing comfort of the user. The vital sign monitoring module 40 is sealingly connected with the mounting groove 12, so as to prevent external moisture from entering the mounting cavity 21 through the mounting groove 12, thereby achieving waterproof protection for the electrical devices in the mounting base 20.

[0069] Specifically, as shown in FIG. 6, the ring type automobile key further comprises a circuit board 50 installed in the mounting cavity 21, and the communication module 30 is installed on the circuit board 50; the mounting groove 12 penetrates through the mounting cavity 21, and the vital sign monitoring module 40 is electrically connected with the circuit board 50. In this way, the vital sign monitoring module 40 can share the circuit board 50 with the communication module 30, and the user can wirelessly control the vital sign monitoring module 40 through the communication module 30, so as to improve the control convenience of the vital sign monitoring module 40.

[0070] The communication module 30 and the vital sign monitoring module 40 can be connected on the same surface of the circuit board 50, or connected on different surfaces of the circuit board 50.

[0071] Specifically, as shown in FIG. 6, the communication module 30 is installed on the surface of the circuit board 50 away from the mounting groove 12, and the vital sign monitoring module 40 is electrically connected with the surface of the circuit board 50 facing the mounting groove 12. Since the vital sign monitoring module 40 does not extend into the mounting cavity 21, even if the vital sign monitoring module 40 and the communication module 30 are installed on different surfaces of the circuit board 50, the space utilization of the mounting cavity 21 will not be affected, and the connection of the vital sign monitoring module 40 and the circuit board 50 will not be hindered by the communication module 30, so as to make the device layout in the mounting base 20 more reasonable.

[0072] In actual application, as shown in FIG. 6, the surface of the circuit board 50 facing the mounting groove 12 is provided with a conductive boss 51, the conductive boss 51 extends into the mounting groove 12, and the vital sign monitoring module 40 is connected with the conductive boss 51. The conductive boss 51 can ensure the stable electrical connection between the circuit board 50 and the vital sign monitoring module 40, so as to improve the stability of the vital sign monitoring function of the ring type automobile key.

[0073] The ring 10 and the mounting base 20 can be integrally formed, or can be separately formed and then connected together.

[0074] For example, the ring 10 and the mounting base 20 can be integrally formed, for example, by integrally injection molding or integrally casting, so as to improve the overall structural strength and connection strength of the ring 10 and the mounting base 20, and further improve the appearance integrity of the ring-shaped automobile key. In combination with the above-mentioned embodiments of the mounting groove 12, the integrally formed ring 10 and mounting base 20 can also make the mounting groove 12 more easily penetrate the mounting cavity 21, and improve the overall sealing effect of the mounting base 20.

[0075] For example, the ring-shaped automobile key further comprises a near field communication unit (NFC) installed in the mounting cavity 21. The near field communication unit enables the ring-shaped automobile key to exchange data with a device using the same technology when they are close to each other, so as to realize mobile payment, electronic ticketing, access control, mobile identity recognition, anti-counterfeiting and other applications. Thus, the function of the ring-shaped automobile key can be further increased, and the use scenarios of the ring-shaped automobile key are expanded.

[0076] Specifically, as shown in FIG. 6, the mounting cavity 21 has an opening facing away from the wearing space 11, and the ring-shaped automobile key further comprises a decorative cover plate 60 covering the opening of the mounting cavity 21, and the near field communication unit is arranged adjacent to the decorative cover plate 60. During the process of manufacturing the ring-shaped automobile key, the communication module 30 and other functional elements can be loaded 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 60, and the decorative cover plate 60 is sealingly connected with the mounting base 20. The decorative cover plate 60 can also play a decorative role for the ring-shaped automobile key, so as to realize the wearing and decorative effect of the ring-shaped automobile key. When the user uses the ring-shaped automobile key to realize the near field communication function, the decorative cover plate 60 can be close to or abut against the target device, and since the near field communication unit is adjacent to the decorative cover plate 60, the data exchange with the target device can be faster and more reliable, and the near field communication application function can be realized.

[0077] The present application provides a ring-shaped automobile key, aiming to solve the technical problem of how to improve the functional effect of the ring-shaped automobile key.

[0078] In the embodiments of the present application, as shown in FIGS. 7-8, FIG. 7 is a structural schematic diagram of an embodiment of the ring-shaped automobile key of the present application; FIG. 8 is a structural exploded view of an embodiment of the ring-shaped automobile key of the present application; and FIG. 9 is a structural sectional view of an embodiment of the ring-shaped automobile key of the present application.

[0079] The ring type automobile key comprises a ring 10, a mounting seat 20, a communication module 30, a battery 40 and a wireless charging receiving unit 50.

[0080] In the embodiment, the ring type automobile key can be understood as loading the car control function of the automobile key in the smart ring, so that the user can control the automobile through the smart ring worn on the finger. The ring type automobile key can only have the function of controlling the automobile, or can also have the functions of near field communication (NFC) and vital sign detection.

[0081] The ring 10 is annular, used for wearing on the human finger, and the user can wear the ring 10 on the finger by putting the finger through the wearing space 11. When the ring type automobile 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 a containing space for the communication module 30, so as to hide and protect the communication module 30.

[0082] The communication module 30 is used for realizing wireless communication with the automobile, so that the user can control the automobile through the ring type automobile key. The communication form of the communication module 30 and the vehicle system is various, for example, wireless communication can be realized through Bluetooth, 3G network, 4G network or 5G network, etc., which is not limited here.

[0083] For example, the communication module 30 can be part of a smart key system, a smart key system (PASSIVE KEYLESS ENTER), referred to as PKE, 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 a remote control system and a keyless system, and follows the traditional whole vehicle circuit protection, realizes a double radio frequency system, and realizes double anti-theft protection. In the PKE system, the automobile is used as a base station, and the ring type automobile key is used as a transponder to realize bidirectional communication. The communication module 30 comprises a receiving antenna, a microcontroller, a high-frequency transmitting circuit, a low-frequency receiving circuit and a control switch and the like.

[0084] Of course, the communication module 30 can also be an element in an ultra-wideband wireless carrier communication technology. Ultra-wideband (UltraWide Band), abbreviated as UWB, uses a new ultra-wideband wireless technology that is very different from traditional communication technologies. The transmission and reception of extremely narrow pulses with nanoseconds or less are used to transmit data to vehicles, with a bandwidth of 3.1-10.6 GHz, which is not easily disturbed by other signals.

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 work of the wireless charging receiving unit 50 on the circuit board 60, thereby improving the structural stability of the circuit board 60.

[0093] Specifically, as shown in FIG. 8 and FIG. 9, the supporting protrusion 22 is annularly arranged and forms 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 fixed cooperation between the positioning boss 61 and the positioning groove 221 can prevent the circuit board 60 from shaking or rotating randomly in the mounting cavity 21, so as to improve the installation stability of the circuit board 60.

[0094] The ring 10 and the mounting seat 20 can be integrally machined and formed, or can be separately machined and formed and then connected together.

[0095] Specifically, the ring 10 and the mounting seat 20 are integrally formed, for example, can be integrally injection molded or integrally cast molded, so as to improve the overall structural strength and connection strength of the ring 10 and the mounting seat 20, and further improve the appearance integrity of the ring-shaped car key.

[0096] Specifically, the mounting cavity 21 has an opening facing away from the wearing space 11, and the ring-shaped automobile key further comprises a decorative cover plate 70 covering the opening of the mounting cavity 21, 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-shaped automobile key, the functional elements such as the communication module 30 can be loaded 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 sealingly connected with the mounting seat 20. The decorative cover plate 70 can also play a decorative role for the ring-shaped automobile key, so as to realize the wearing and decorative effect of the ring-shaped automobile key.

[0097] In combination with the above-mentioned embodiment that the ring 10 is integrally formed with the mounting seat 20, the ring 10 and the mounting seat 20 can be made of a metal material to improve the anti-impact capability; the decorative cover plate 70 can be a glass plate or a plastic plate, and the decorative cover plate 70 is arranged as a non-metallic cover plate, so that the signals of the communication module 30 can pass through the decorative cover plate 70 to enter or exit the mounting cavity 21, thereby ensuring that the ring-shaped automobile key can correctly identify the vehicle signals, and improving the control effect on the automobile.

[0098] In actual application, as shown in FIG. 7, the ring 10 is provided with a deformation gap 12 opposite to the position where the mounting seat 20 is located. When a user wears the ring-shaped automobile key, the ring 10 can be appropriately expanded through the deformation gap 12, so as to reduce the wearing difficulty of the user and improve the wearing convenience.

[0099] In the technical scheme of the ring-shaped automobile key, the signals transmitted and / or received by the communication module 30 can interact with external vehicles or accessories, so that the ring-shaped automobile key can correctly identify the vehicle signals and realize the control on the automobile.
