[0038] With the continuous development of technology, smartwatches have become an indispensable part of people's lives. One particularly convenient function is the ability to operate car keys through smartwatches. Communication components installed in the watch receive and transmit frequency signals from the vehicle's computer system, allowing users to operate the car key function of the vehicle system through the watch. However, existing smartwatches typically place the communication components inside the watch, which is susceptible to interference from the watch's metal casing and internal electronic components. This high degree of interference reduces the communication components' receiving and transmitting signal performance, making it impossible for the watch to accurately identify vehicle signals, which can easily lead to vehicle signal reception failure and thus fail to meet the requirements of the car key function.

[0039] The utility model provides a dial-type automobile key, aiming to solve the technical problem of how to improve the signal transmission effect between the dial-type automobile key and the automobile.

[0040] In the embodiment of the present utility model, Figures 1 to 3 As shown, the watch head type car key includes: a watch head 10, the watch head 10 includes a shell 11 and a main control board 12, the shell 11 is provided with a mounting cavity 111, the main control board 12 is mounted in the mounting cavity 111; a watch strap 20, the watch strap 20 is connected to the shell 11, and is used for being worn by a human body; a watch clasp 30, the watch clasp 30 is connected to the watch strap 20, and is used to adjust the wearing length of the watch strap 20; a communication element 40, the communication element 40 is mounted on the watch clasp 30, and the communication element 40 is used to communicate with the vehicle's The car system is communicated with the watch head type car key so that the car can be controlled through the communication element 40; the vital sign monitoring module 70, the vital sign monitoring module 70 is installed on the watch buckle 30 and is at least partially exposed on the surface of the watch buckle 30; the electrical connector 50, the electrical connector 50 extends along the strap 20, one end of the electrical connector 50 extends to the watch buckle 30, and the other end extends to the watch head 10, the electrical connector 50 electrically connects the communication element 40 and the vital sign monitoring module 70 with the main control board 12.

[0041] In this embodiment, the watch-style car key can be understood as integrating the car key's car control functions into a smartwatch, allowing the user to control the car through the smartwatch worn on their wrist. The watch-style car key can have only the car control function, or it can also have other functions such as displaying the time and providing information reminders.

[0042] The housing 11 of the keypad 10 may include a middle frame 112, a display panel, and a bottom housing. The display panel and bottom housing are mounted to the top and bottom of the middle frame 112, respectively. The display panel, middle frame 112, and bottom housing together form a mounting cavity 111. The mounting cavity 111 accommodates and protects the main control board 12. The middle frame 112 may be metal, which imparts a more metallic appearance to the housing 11 and enhances its overall structural strength, thereby improving the keypad-style car key's resistance to impact.

[0043] The watch strap 20 can be worn around the wrist of the user to realize the wearing of the watch head type car key. The watch strap 20 can be made of leather, TPU or silicone. The watch strap 20 can be a single-piece or a two-piece.

[0044] The clasp 30 allows the user to adjust the length of the watchband 20, allowing the user to adjust the tightness of the watchband 20 according to the thickness of the wrist. Of course, for a two-piece watchband 20, the clasp 30 is also used to connect or disconnect the two sections of the watchband 20, allowing the user to adjust the length of the watchband 20 simultaneously. Depending on the specific form, the clasp 30 may include a hook, concealed buckle, butterfly buckle, belt snap, folding safety buckle, folding buckle, or pin buckle.

[0045] The clasp 30 can be metal or non-metallic. For example, if the communication element 40 is mounted on the surface of the clasp 30 or exposed on the clasp 30, then whether the clasp 30 is metal or non-metallic will not shield the signal of the communication element 40.

[0046] Communication element 40 is used to wirelessly communicate with the vehicle, allowing the user to control the vehicle via a key fob, such as locking and unlocking the vehicle. Communication element 40 can communicate with the vehicle's computer system in a variety of ways, including Bluetooth, 3G, 4G, or 5G networks, without limitation.

[0047] For example, communication element 40 can be part of a smart key system, a PASSIVE KEYLESS ENTER (PKE). This system utilizes RFID wireless radio frequency technology and a vehicle identification code recognition system. It utilizes a miniaturized, low-power radio frequency antenna development solution, integrates a remote control system with a keyless entry system, and utilizes 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 head-mounted car key serves as a transponder to enable two-way communication. Communication element 40 includes components such as a receiving antenna, a microcontroller, a high-frequency transmitting circuit, a low-frequency receiving circuit, and a control switch.

[0048] Of course, the communication element 40 can also be an element in ultra-wideband wireless carrier communication technology. Ultra-wideband (UWB) is abbreviated as UWB, which uses a new ultra-wideband wireless technology that is very different from traditional communication technology. It sends and receives extremely narrow pulses of nanoseconds or less to transmit data to the vehicle, has a bandwidth of 3.1 to 10.6 GHz, and is not easily interfered with by other signals. Through the interaction between the UWB of the head-type car key and the UWB of the vehicle, the positioning algorithm characteristics can be used to identify the centimeter-level distance to the vehicle, and quickly respond easily, so that users wearing the head-type car key can automatically control the car without feeling.

[0049] The communication element 40 can be a component that can emit signals on its own, or it can be a signal amplifier that receives signals and then amplifies the signal strength before re-emitting it, without limitation. The main control board 12 can distribute power and transmit control signals to the communication element 40 via the electrical connector 50, so that the communication element 40 can operate or enter standby mode according to user control instructions.

[0050] The electrical connector 50 can be a conductive wire harness or a flexible printed circuit (FPC), without limitation. The electrical connector 50 can extend along the surface of the watchband 20 or extend inside the watchband 20, without limitation. It is understood that the electrical connector 50 is flexible and bendable so that the electrical connector 50 can bend and deform along with the watchband 20. Compared to conductive wires, flexible printed circuits have a larger width, better toughness, and are less likely to break, which can improve the structural stability of the electrical connector 50. High-frequency circuits can also be integrated on the flexible printed circuit board, so that the communication element 40 can simultaneously have high-frequency signal transmission functions and low-frequency signal transmission functions.

[0051] Since the communication element 40 is installed on the watch buckle 30, that is, outside the installation cavity 111, the metal and screen and other electronic component structures of the shell 11 can avoid interfering with or shielding the communication signal of the communication element 40, so that the signals transmitted and / or received by the communication element 40 can interact with external vehicles or accessories, ensuring that the watch-type car key can correctly identify the vehicle signal to improve the control effect of the car.

[0052] The vital sign monitoring module 70 is used to monitor a person's vital sign parameters, such as at least one of body temperature, blood oxygen level, heart rate, and blood pressure. A vital sign monitoring circuit is provided on the main control board 12 and is electrically connected to the vital sign monitoring module 70. The vital sign monitoring module 70 is at least partially exposed on the outer surface of the clasp 30. Thus, when a user wears the watch-style car key, the vital sign monitoring module 70 can contact the user's wrist skin, cooperating with the vital sign monitoring circuit to monitor the wearer's vital sign parameters.

[0053] The monitoring results of the vital sign monitoring module 70 can be displayed through the display component installed on the header 10, played through the playback component installed on the header 10, and transmitted to the user's mobile device through the communication element 40 for the user to read, without limitation here.

[0054] Specifically, the watch-type car key further includes a geolocation module mounted on the fob 30, which is electrically connected to the electrical connector 50. The geolocation module may be a Global Positioning System (GPS) module, which allows a user to obtain their current geographic location and the distance between the user and the car, thereby further improving the usability of the watch-type car key.

[0055] For example, Figure 4 and Figure 5 As shown, the clasp 30 is a non-metallic part. The clasp 30 is provided with a receiving cavity 31 and a wiring opening connected to the receiving cavity 31. The communication element 40 is installed in the receiving cavity 31. One end of the electrical connector 50 extends into the receiving cavity 31 through the wiring opening to electrically connect with the communication element 40. Installing the communication element 40 in the receiving cavity 31 can hide and protect the communication element 40, thereby improving the appearance and integrity of the clasp 30 and improving the protection of the communication element 40. The clasp 30 can be a plastic part or a ceramic part, and there is no limitation here. The clasp 30 only needs to be a metal part to avoid the metal from causing shielding interference to the signal of the communication element 40.

[0056] Specifically, such as Figure 5 As shown, the clasp 30 includes a clasp body 33 and a cover 34. The clasp body 33 and the cover 34 enclose the receiving cavity 31. The clasp body 33 is connected to the watchband 20, and the communication component 40 is connected to the clasp body 33. The cover 34 and the clasp body 33 are connected by a sealant to seal the receiving cavity 31. This prevents external moisture or dust from entering the receiving cavity 31 and affecting the operation of the communication component 40, thereby further improving the protection of the communication component 40.

[0057] In another embodiment, the cover 34 is detachably connected to the buckle body 33 to open or close the receiving cavity 31. When the communication component 40 needs to be inspected or replaced, the cover 34 can be removed to open the receiving cavity 31 and expose the communication component 40, thereby simplifying the inspection and replacement process of the communication component 40. The connection between the cover 34 and the buckle body 33 can be a snap-fit connection or a fastener connection, without limitation, as long as the connection is detachable.

[0058] In practical applications, such as Figure 5 As shown, the outer surface of the cover body 34 is provided with a receiving groove 341, and the bottom of the receiving groove 341 is provided with a wiring hole that communicates with the receiving cavity 31. The vital sign monitoring module 70 is installed in the receiving groove 341 and is electrically connected to the electrical connector 50 through the wiring hole. The receiving groove 341 can increase the matching area between the vital sign monitoring module 70 and the clasp 30 to improve the matching stability of the vital sign monitoring module 70 and the clasp 30. One side of the vital sign monitoring module 70 is exposed at the notch of the receiving groove 341 to effectively contact the user's wrist skin; the other side of the vital sign monitoring module 70 is electrically connected to the electrical connector 50 through the wiring hole to effectively connect to the main control board 12.

[0059] For example, Figure 2 As shown, the strap 20 is provided with a wiring channel, one end of which is connected to the wiring port, and the electrical connector 50 is provided in the wiring channel, one end of which passes through the strap 20 and extends into the accommodating cavity 31 through the wiring port.

[0060] The watch strap 20 is non-metallic, and can be made of materials such as leather, TPU, or silicone. This prevents the watch strap 20 from conducting electricity and potentially short-circuiting the watch head car key. A wiring channel extends along the length of the watch strap 20, and the portion of the electrical connector 50 extending along the watch strap 20 is located within the wiring channel, thereby concealing and protecting the electrical connector 50, improving the overall appearance of the watch strap 20 and enhancing its protection.

[0061] Specifically, such as Figure 1 As shown, the strap 20 includes a first strap body 21 and a second strap body 22, and the first strap body 21 and the second strap body 22 are respectively connected to the opposite sides of the shell 11, and the buckle 30 is connected to the end of the first strap body 21. The second strap body 22 is provided with at least two connection positions 221, and the at least two connection positions 221 are spaced apart along the length direction of the second strap body 22, and the at least two connection positions 221 can be switchably connected to the buckle 30; the wiring channel is provided in the first strap body 21, and the wiring channel passes through the end of the first strap body 21 close to the buckle 30 to communicate with the wiring port.

[0062] The connection point 221 may be a connection hole, and the clasp 30 may be provided with a protruding connection post that can be removably connected to different connection holes, thereby enabling switchable connection between each connection point 221 and the clasp 30. By connecting the clasp 30 to different connection points 221, the user can select a suitable wearing length for the watchband 20 on the wrist. The clasp 30 is connected to the end of the first strap 21 away from the housing 11. The electrical connector 50 extends within the first strap 21 and passes through the end of the first strap 21 near the clasp 30.

[0063] In practical applications, such as Figure 5 As shown, the clasp 30 is provided with a connecting groove, into which the end of the first strap 21 is inserted, and the cable routing opening is located. The first strap 21 and the groove wall of the connecting groove can be fixed by adhesive bonding or heat pressing, without limitation. The connecting groove increases the connection area between the first strap 21 and the clasp 30, thereby improving the connection strength between the clasp 30 and the first strap 21.

[0064] The electrical connector 50 and the main control board 12 in the installation cavity 111 can be directly connected to each other for power supply, or can be indirectly connected to each other for power supply via an intermediate conductor, which is not limited here.

[0065] For example, Figures 4 to 6 As shown, the housing 11 includes a middle frame 112, which defines a wire passage 113 that communicates with the mounting cavity 111. The wire passage passes through the end of the watchband 20 closest to the middle frame 112. One end of the electrical connector 50 passes through the watchband 20 and extends into the mounting cavity 111 through the wire passage 113. The electrical connector 50 extends directly into the mounting cavity 111 through the wire passage 113 and then connects to the main control board 12. This allows direct electrical connection between the electrical connector 50 and the main control board 12, eliminating the need for an additional intermediate conductor. This simplifies the electrical connection between the electrical connector 50 and the main control board 12 and improves electrical stability.

[0066] Specifically, such as Figure 3 and Figure 6 As shown, the outer wall of the middle frame 112 is provided with an assembly groove 114, and the wire passing opening 113 is provided at the bottom of the assembly groove 114; the end of the strap 20 is provided with an assembly boss 23, and the wiring channel passes through the assembly boss 23, and the assembly boss 23 is fixedly matched with the assembly groove 114.

[0067] A mounting boss 23 protrudes from the end of the watchband 20 near the housing 11. The mounting boss 23 cooperates with the mounting groove 114 to securely connect the watchband 20 to the housing 11. A wiring channel extends through the end wall of the mounting boss 23, allowing the electrical connector 50 to pass through the mounting boss 23 and then into the mounting cavity 111 through the wiring opening 113. This allows the portion of the electrical connector 50 between the wiring opening and the watchband 20 to be concealed, providing enhanced protection for the electrical connector 50 and preventing it from coming into contact with the user.

[0068] The strap 20 can be bent and deformed by its own flexibility. When the strap 20 bends, the main deformation position is the part connected to the middle frame 112, and the part of the electrical connector 50 at the wire opening 113 will also be bent repeatedly as the strap 20 deforms.

[0069] In practical applications, such as Figure 3 and Figure 6 As shown, the watch head type car key also includes a protective member 60, and a mounting groove 24 is provided at one end of the watch strap 20 close to the middle frame 112. The mounting groove 24 and the wiring channel are adjacently arranged along the thickness direction of the watch strap 20. A portion of the protective member 60 cooperates with the mounting groove 24, and the other portion extends from the wire opening 113 into the mounting cavity 111 and is connected to the middle frame 112. The protective member 60 is crimped to the electrical connector 50, and the deformation resistance of the protective member 60 is greater than that of the watch strap 20.

[0070] The mounting slot 24 may intersect the wiring channel or be separated from the wiring channel by a flexible barrier, without limitation. The protective member 60 is elastically deformable and may be made of leather, silicone, or TPU, without limitation. The portion of the electrical connector 50 at the wiring opening 113 is sandwiched between the protective member 60 and the watchband 20. Because the protective member 60 has a greater deformation resistance than the watchband 20, meaning that the deformation of the protective member 60 is smaller than that of the watchband 20 under the same force, the bending deformation of the watchband 20 near the housing 11 is limited, thereby correspondingly reducing the deformation of the electrical connector 50 near the protective member 60. This prevents the electrical connector 50 from being repeatedly bent significantly, preventing the portion of the electrical connector 50 at the wiring opening 113 from easily breaking, which could lead to poor electrical connection between the main control board 12 and the communication component 40. This improves the structural stability of the electrical connector 50 and the electrical connection stability between the main control board 12 and the communication component 40.

[0071] For example, Figure 4 As shown, the outer wall of the middle frame 112 is provided with at least two stopper protrusions 115 spaced apart along the circumference of the middle frame 112. The wire-passing opening 113 is located between two adjacent stopper protrusions 115. The end of the watchband 20 connected to the middle frame 112 is located between the two adjacent stopper protrusions 115. There can be one stopper protrusion 115, with each pair of adjacent stopper protrusions 115 forming a group. Two groups of stopper protrusions 115 are used to stop the ends of the watchband 20, respectively. Two adjacent stopper protrusions 115 are located on opposite sides of the width of the watchband 20, thereby limiting deformation of the ends of the watchband 20 along the width direction, reducing deformation of the electrical connector 50 along the width direction of the watchband 20, further preventing the electrical connector 50 from being torn and fractured, and further improving the protection of the electrical connector 50.

[0072] The present invention also provides an automobile assembly, comprising an automobile and a dial-type automobile key. The detailed structure of the dial-type automobile key is similar to that of the aforementioned embodiments. Since the present automobile assembly utilizes all the technical solutions of all the aforementioned embodiments, it at least possesses all the beneficial effects of the technical solutions of the aforementioned embodiments, which will not be detailed here. The dial-type automobile key is communicatively connected to the automobile.

[0073] In the technical solution of the watch-type car key of the present invention, the communication element 40 is installed on the watch buckle 30, and the communication element 40 is electrically connected to the main control board 12 via the electrical connector 50, so that the main control board 12 can provide power to the communication element 40 and transmit control signals to control the communication element 40 to transmit and receive signals. Because the communication element 40 is installed on the watch buckle 30, that is, outside the installation cavity 111, it can prevent the metal and screen and other electronic components of the housing 11 from interfering with or shielding the communication signal of the communication element 40, so that the signals transmitted and / or received by the communication element 40 can interact with the external vehicle or accessories, ensuring that the watch-type car key can correctly identify vehicle signals to improve the control effect of the car. In addition, the vital signs monitoring module 70 can monitor the wearer's vital signs through the wearer's wrist, so that the user can use the watch-type car key to obtain their own vital signs parameters, so that the watch-type car key can meet the different functional needs of the user and improve the functional effect of the watch-type car key.

[0074] The above description is merely an optional embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by utilizing the contents of the present invention specification and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
