[0038] 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.

[0039] In the embodiment of the present utility model, Figures 1 to 5 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 and a wire port 111 connected to the mounting cavity, and the main control board 12 is installed in the mounting cavity; a watch strap 20, the watch strap 20 is connected to the shell 11 for being worn by a human body; a communication element 30, the communication element 30 is installed on the watch strap 20, the communication element 30 is used to communicate with the car's vehicle system so that the watch head type car key can control the car through the communication element 30; a geolocation module 70, the geolocation module 70 is installed on the watch strap 20; an electrical connector 40, the electrical connector 40 extends along the watch strap 20, one end of the electrical connector 40 is electrically connected to the communication element 30 and the geolocation module 70, and the other end extends from the wire port 111 into the mounting cavity and is electrically connected to the main control board 12.

[0040] 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.

[0041] 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. The mounting cavity accommodates and protects the main control board 12. The middle frame 112 may be metal, which lends the housing 11 a more metallic appearance and enhances its overall structural strength, thereby improving the keypad-style car key's resistance to impact.

[0042] 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.

[0043] Communication element 30 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 30 can communicate with the vehicle's computer system in a variety of ways, including Bluetooth, 3G, 4G, or 5G networks, without limitation.

[0044] For example, communication element 30 can be part of a smart key system, known as 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 meter-mounted car key serves as a transponder, enabling two-way communication. Communication element 30 includes components such as a receiving antenna, a microcontroller, a high-frequency transmitting circuit, a low-frequency receiving circuit, and a control switch.

[0045] Of course, the communication element 30 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.

[0046] The communication element 30 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 30 via the electrical connector 40, so that the communication element 30 can operate or enter standby mode according to user control instructions.

[0047] The electrical connector 40 can be a conductive wire harness or a flexible printed circuit (FPC), and there is no limitation here. The electrical connector 40 can extend along the surface of the strap 20 or extend inside the strap 20, and there is no limitation here. It can be understood that the electrical connector 40 is flexible and bendable so that the electrical connector 40 can bend and deform along with the strap 20. Compared with 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 40. High-frequency circuits can also be integrated on the flexible printed circuit board, so that the communication element 30 can have both high-frequency signal transmission functions and low-frequency signal transmission functions.

[0048] The electrical connector 40 is directly inserted into the installation cavity through the wire opening 111 and connected to the main control board 12, so that the electrical connector 40 and the main control board 12 can be directly powered without the need for an additional intermediate conductor, thereby simplifying the power supply method between the electrical connector 40 and the main control board 12 and improving the power supply stability.

[0049] Since the communication element 30 is installed on the watch strap 20, that is, on the outside of the shell 11, the metal and screen and other electronic components of the shell 11 can avoid interfering with or shielding the communication signal of the communication element 30, so that the signals transmitted and / or received by the communication element 30 can interact with the external vehicle or accessories, ensuring that the watch-type car key can correctly identify the vehicle signal to improve the control effect of the car.

[0050] The geolocation module 70 may be a global positioning system (GPS) module. The geolocation module 70 allows the user to obtain his or her current geographic location and the distance between the user and the car, thereby further improving the use of the dial-type car key.

[0051] Exemplarily, the watch-type car key further includes a vital sign monitoring module installed on the watch strap 20 , wherein the vital sign monitoring module is at least partially exposed on the outer surface of the watch strap 20 , and the vital sign monitoring module is electrically connected to the electrical connector 40 .

[0052] The vital sign monitoring module 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. The main control board 12 includes a vital sign monitoring circuit electrically connected to the vital sign monitoring module. When a user wears the keypad-style car key, the vital sign monitoring module can contact the user's wrist skin to cooperate with the vital sign monitoring circuit to monitor the wearer's vital sign parameters.

[0053] The communication element 30 and the geo-positioning module 70 can be installed on the surface of the strap 20 or inside the strap 20, and there is no limitation here.

[0054] Specifically, such as Figure 5 As shown, the strap 20 is provided with a receiving cavity 21 and a wiring channel 22. The wiring channel 22 extends along the length direction of the strap 20. One end of the wiring channel 22 is connected to the receiving cavity 21, and the other end passes through the end of the strap 20 close to the housing 11; the communication element 30 and the geo-positioning module 70 are provided in the receiving cavity 21, and the electrical connector 40 is provided in the wiring channel 22.

[0055] Mounting the communication element 30 and geolocation module 70 within the accommodating cavity 21 conceals and protects them, enhancing their protective properties. The watchband 20 is made of a non-metallic material, such as leather, TPU, or silicone, to prevent the strap 20 from conducting electricity and potentially causing electric shock. A wiring channel 22 extends along the length of the watchband 20, with the portion of the electrical connector 40 extending along the strap 20 located within the wiring channel 22. This conceals and protects the electrical connector 40, enhancing the overall appearance of the watchband 20 and improving its protective properties.

[0056] For example, Figure 3 、 Figure 5 and Figure 6 As shown, the shell 11 includes a middle frame 112, the outer wall of the middle frame 112 is provided with an assembly groove 113, and the wire passing opening 111 is provided at the bottom of the assembly groove 113; the end of the strap 20 is provided with an assembly boss 23, the wiring channel 22 passes through the assembly boss 23, and the assembly boss 23 is fixedly matched with the assembly groove 113.

[0057] The assembly boss 23 is protruding from one end of the watchband 20 close to the housing 11. The assembly boss 23 cooperates with the assembly groove 113 to achieve a fixed connection between the watchband 20 and the housing 11. In combination with the above-mentioned embodiment of the wiring channel 22, the wiring channel 22 can pass through the end wall of the assembly boss 23, so that the electrical connector 40 can pass through the assembly boss 23 and then extend into the installation cavity from the wire opening 111. In this way, the portion of the electrical connector 40 exposed at the wire opening 111 can be wrapped and hidden to improve the protection of the electrical connector 40 and prevent the electrical connector 40 from contacting the user. In addition, the assembly boss 23 can also block the wire opening 111, preventing external moisture and dust from entering the installation cavity from the wire opening 111, thereby improving the protection of the components in the installation cavity. The assembly boss 23 can be integrally formed with the watchband 20 to simplify the processing and forming method of the assembly boss 23.

[0058] Specifically, such as Figure 6 As shown, the side wall of the assembly boss 23 is provided with a sealing rib 231, and the sealing rib 231 extends along the circumference of the wire-passing opening 111. The assembly boss 23 and the assembly groove 113 are sealed and matched through the sealing rib 231. The sealing rib 231 can be protruded from the peripheral wall of the assembly boss 23, or can be protruded from the end wall of the assembly boss 23, and there is no restriction here. It is only necessary that the sealing rib 231 can be arranged around the wire-passing opening 111 and abut against the groove wall or groove bottom of the assembly groove 113. The sealing rib 231 can seal the gap between the assembly boss 23 and the assembly groove 113 to further prevent external dust and moisture from entering the installation cavity from the wire-passing opening 111, thereby further improving the protection effect of the components in the installation cavity. The sealing rib 231 can be integrally formed with the assembly boss 23 to simplify the processing and forming method of the sealing rib 231.

[0059] The strap 20 can bend and deform through its own flexibility. When the strap 20 bends, the main deformation location is the part connected to the middle frame 112, and the part of the electrical connector 40 at the wire opening 111 will also be bent repeatedly as the strap 20 deforms.

[0060] In practical applications, such as Figures 3 to 6 As shown, the watch head type car key also includes a protective member 50, 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 22 are adjacently arranged along the thickness direction of the watch strap 20. A portion of the protective member 50 cooperates with the mounting groove 24, and the other portion extends into the mounting cavity from the wire passing opening 111 and is connected to the middle frame 112. The protective member 50 is crimped to the electrical connector 40, and the deformation resistance of the protective member 50 is greater than that of the watch strap 20.

[0061] The mounting groove 24 may intersect with the wiring channel 22 or be separated from the wiring channel 22 by a flexible barrier, without limitation. The protective member 50 is elastically deformable and may be made of leather, silicone, or TPU, without limitation. The portion of the electrical connector 40 at the wiring opening 111 is sandwiched between the protective member 50 and the watchband 20. Because the protective member 50 has a greater deformation resistance than the watchband 20, meaning that the deformation of the protective member 50 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 40 near the protective member 50. This prevents the electrical connector 40 from being repeatedly bent significantly, preventing the portion of the electrical connector 40 at the wiring opening 111 from easily breaking, which could lead to poor electrical connection between the main control board 12 and the communication component 30. This improves the structural stability of the electrical connector 40 and the electrical connection stability between the main control board 12 and the communication component 30.

[0062] For example, Figure 4 As shown, the outer wall of the middle frame 112 is provided with at least two stopper protrusions 114 spaced apart along the circumference of the middle frame 112. The assembly slot 113 is located between two adjacent stopper protrusions 114. One end of the watchband 20 connected to the middle frame 112 is located between two adjacent stopper protrusions 114. The number of stopper protrusions 114 can be four, with each pair of adjacent stopper protrusions 114 forming a group. Two groups of stopper protrusions 114 are used to stop the ends of the watchband 20, respectively. Two adjacent stopper protrusions 114 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 40 along the width direction of the watchband 20, further preventing the electrical connector 40 from being pulled apart and breaking, and further improving the protection of the electrical connector 40.

[0063] Specifically, such as Figure 4 and Figure 5 As shown, a bulge 25 is formed on the outer wall of the watch strap 20 at a location corresponding to the receiving cavity 21. The watch head-type car key also includes a clasp 60, which is connected to the watch strap 20 and covers the bulge 25. The clasp 60 is used to adjust the wearing length of the watch strap 20. The thickness of the watch strap 20 at the bulge 25 is greater than that at other locations, thereby maintaining a relatively small thickness of the watch strap 20 as a whole.

[0064] The clasp 60 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-section watchband 20, the clasp 60 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 while connecting the two sections. Depending on the specific form, the clasp 60 may include a hook, a concealed buckle, a butterfly buckle, a belt snap, a folding safety buckle, a folding buckle, or a pin buckle. The clasp 60 may be non-metallic to avoid shielding interference with the signal of the communication element 30. The clasp 60 may also cover and protect the bulge 25, thereby improving the overall appearance of the watchband 20 and further enhancing the protection of the communication element 30.

[0065] In practical applications, such as Figure 1 As shown, the strap 20 includes a first strap body 26 and a second strap body 27, and the first strap body 26 and the second strap body 27 are respectively connected to the opposite sides of the shell 11, the receiving cavity 21 and the wiring channel 22 are provided on the first strap body 26, the buckle 60 is connected to the end of the first strap body 26, and the second strap body 27 is provided with at least two connection positions 271, and the at least two connection positions 271 are arranged at intervals along the length direction of the second strap body 27, and the at least two connection positions 271 can be switchably connected to the buckle 60.

[0066] The connection point 271 may be a connection hole, and the clasp 60 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 271 and the clasp 60. By connecting the clasp 60 to different connection points 271, the user can select a suitable wearing length for the watchband 20 on the wrist. The clasp 60 is connected to the end of the first strap 26 away from the housing 11. The electrical connector 40 extends within the first strap 26 and passes through the end of the first strap 26 near the clasp 60.

[0067] 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.

[0068] In the technical solution of the watch-type car key of the present invention, the communication element 30 is installed on the watch strap 20 and electrically connected to the main control board 12 via the electrical connector 40. Thus, the main control board 12 can provide power to the communication element 30 and transmit control signals to control the communication element 30 to transmit and receive signals. Because the communication element 30 is installed on the watch strap 20, that is, on the outside of the housing 11, it can prevent the metal and screen and other electronic components of the housing 11 from interfering with or shielding the communication signals of the communication element 30. This allows the signals transmitted and / or received by the communication element 30 to 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 geo-positioning module 70 allows the wearer to obtain their current geographic location and the distance between themselves and the car, so that the watch-type car key can meet the different functional needs of users and improve the functional effect of the watch-type car key.

[0069] 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.
