[0035] With the continuous development of science and technology, smart watches have become an indispensable part of people's lives. Among them, a very convenient function is to realize the operation of car keys through smart watches. The communication components installed in the watch receive and transmit the frequency signals of the vehicle system, allowing users to operate the car key function of the vehicle system through the watch. In related technologies, smart watches usually place the communication components inside the watch. Smart watches also have the function of voice calls. The speakers for playing voices are placed inside the watch. However, the speakers are metal devices and are prone to interference with the communication components. Due to the high degree of interference with the communication components, the receiving and transmitting signal performance of the communication components is reduced, making it impossible for the watch to accurately identify the vehicle signal, which can easily cause the vehicle signal reception to fail, and thus fail to meet the normal car key function requirements.

[0036] The main purpose of the utility model is to provide a head-type automobile key, aiming to solve the technical problem of how to improve the signal transmission effect between the head-type automobile key and the automobile.

[0037] In the embodiment of the present utility model, Figures 1 to 3 As shown, Figure 1 This is a structural diagram of an embodiment of a dial-type automobile key of the utility model; Figure 2 This is a cross-sectional view of an embodiment of a dial-type automobile key of the present utility model; Figure 3 for Figure 2 A partial enlarged view of point A in the middle.

[0038] The watch head type car key comprises: a watch head 10, the watch head 10 comprises a shell 11, a main control board 12 and a communication element 40, the shell 11 is provided with a mounting cavity 111 and a wire port 113 communicating with the mounting cavity 111, the main control board 12 is mounted in the mounting cavity 111, the communication element 40 is mounted on the main control board 12, the communication element 40 is used to communicate with the vehicle's on-board system so that the watch head type car key can control the vehicle through the communication element 40; a watch strap 20, the watch strap 20 is connected to the shell 11 for being worn by a human body; a watch buckle 30, the clasp 30 is connected to the strap 20 to adjust the wearing length of the strap 20, and the clasp 30 is provided with a receiving cavity 31 and a sound outlet hole 35 connected to the receiving cavity 31; the speaker 70, the speaker 70 is installed in the receiving cavity 31 and is arranged corresponding to the sound outlet hole 35; the electrical connector 50, the electrical connector 50 extends along the strap 20, one end of the electrical connector 50 extends into the receiving cavity 31 and is electrically connected to the speaker 70, and the other end extends into the installation cavity 111 through the wire opening 113 and is electrically connected to the main control board 12.

[0039] 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.

[0040] 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 communication component 40. The middle frame 112 may be metal, which imparts a more metallic appearance to the housing 11 and enhances the overall structural strength of the housing 11, thereby improving the keypad-style car key's resistance to impact.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] The speaker 70 is a transducer device that converts electrical signals into sound signals. The speaker 70 can play the voice information of the head-type car key. It can not only play the voice information when the user communicates with other communication devices, but also play the voice information when the head-type car key interacts with the user.

[0047] The speaker 70 is installed on the watch buckle 30 and electrically connected to the main control board 12 through the electrical connector 50, so that the speaker 70 can play communication voice and human-computer interaction voice normally, while reducing the interference or shielding of 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.

[0048] Specifically, the dial-type car key further includes a dustproof net or dustproof cotton installed at the sound outlet 35. The dustproof net or dustproof cotton can be installed at the end of the sound outlet 35 away from the receiving cavity 31 to prevent dust from entering the receiving cavity 31 through the sound outlet 35 and then adhering to the speaker 70, thereby preventing the operation of the speaker 70 from being affected, thereby improving the operating stability of the speaker 70.

[0049] The speaker 70 is mounted in the receiving cavity 31 to hide and protect the speaker 70, thereby improving the appearance integrity of the clasp 30 and improving the protection effect of the speaker 70. The clasp 30 can be a metal part, a plastic part, or a ceramic part.

[0050] In practical applications, such as Figure 5 As shown, the clasp 30 includes a clasp body 33 and a cover body 34. The clasp body 33 and the cover body 34 enclose the accommodating cavity 31. The clasp body 33 is connected to the strap 20. The speaker 70 is connected to the clasp body 33. The cover body 34 is connected to the clasp body 33 by sealant. The sound hole 35 is opened in the cover body 34.

[0051] The speaker 70 can be powered by an independent battery or can share the battery in the meter head 10 with the communication element 40. For example, a battery electrically connected to the speaker 70 can be installed in the receiving cavity 31 to provide power to the speaker 70, so that the speaker 70 does not need to be powered by the power supply in the meter head 10.

[0052] The main control board 12 is a circuit board that directly distributes power to the communication element 40 and transmits control signals, enabling the communication element 40 to operate or enter standby mode according to user control commands. The main control board 12 also distributes power to the speaker 70 via an electrical connector 50. The main control board 12 may be integrated with voice communication circuitry or equipped with voice communication components to enable voice communication with the meter. The main control board 12 may also be integrated with high-frequency circuitry, enabling the communication element 40 to transmit both high-frequency and low-frequency signals.

[0053] For example, if Figure 2 and Figure 3 As shown, the dial-type car key also includes a voice communication module and a microphone 80 installed in the installation cavity 111. The voice communication module is installed on the main control board 12, and the microphone 80 is installed on the bottom shell of the shell 11. The bottom shell is provided with a sound receiving hole 116 corresponding to the microphone 80. The user's voice can be collected by the microphone 80 through the sound receiving hole 116. The microphone 80 converts the sound into an electrical signal and transmits it wirelessly through the voice communication module.

[0054] 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 within the watchband 20, without limitation. It will be appreciated that the electrical connector 50 is flexible and bendable, allowing it to flex and deform with the watchband 20. Compared to conductive wires, flexible printed circuits are wider, more resilient, and less prone to breakage, thereby improving the structural stability of the electrical connector 50.

[0055] Specifically, such as Figure 5 As shown, the watch strap 20 is provided with a wiring channel, one end of which communicates with the receiving cavity 31. The electrical connector 50 is disposed within the wiring channel, with one end of the electrical connector 50 extending beyond the watch strap 20 and into the receiving cavity 31. The watch strap 20 is non-metallic, such as leather, TPU, or silicone. This prevents the strap 20 from conducting electricity and causing a short circuit in the watch head car key. The 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, enhancing the visual integrity of the watch strap 20 and providing enhanced protection for the electrical connector 50.

[0056] For example, Figure 1、 Figure 2 and Figure 5 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 away from the shell 11. 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 connected to the buckle 30 to communicate with the receiving cavity 31.

[0057] 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.

[0058] Specifically, such as Figure 5 As shown, the clasp 30 is provided with a connecting groove, into which the end of the first strap 21 distal from the housing 11 is inserted, and the receiving cavity 31 communicates with the connecting groove. The first strap 21 and the groove wall 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.

[0059] 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.

[0060] For example, Figures 4 to 6 As shown, Figure 6 for Figure 5 A partial enlarged view of point B in the center. The housing 11 includes a middle frame 112, which defines a wire passage 113 that communicates with the mounting cavity 111. The wire passage extends 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 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 connects to the main control board 12, enabling direct electrical connection between the electrical connector 50 and the main control board 12 without 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.

[0061] Specifically, such as Figure 3 and Figure 6 As shown, the outer wall of the middle frame 112 is provided with a mounting groove 114, and the cable opening 113 is provided at the bottom of the mounting groove 114. A mounting boss 23 is provided on the end wall of the watchband 20, and the cable routing channel extends through the mounting boss 23, which is fixedly engaged with the mounting groove 114. The mounting boss 23 is provided on the end of the watchband 20 near the outer shell 11, and the mounting boss 23 cooperates with the mounting groove 114 to achieve a fixed connection between the watchband 20 and the outer shell 11. The cable routing 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 extend into the mounting cavity 111 through the cable routing channel 113. This allows the portion of the electrical connector 50 between the cable routing channel and the watchband 20 to be enclosed and concealed, thereby improving protection for the electrical connector 50 and preventing it from coming into contact with the user.

[0062] 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.

[0063] In practical applications, such as Figures 3 to 6 As shown, the watch head type car key also includes a protective member 60, and the end wall of the watch strap 20 is provided with a mounting groove 24, and 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.

[0064] 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 result in poor electrical connection between the main control board 12 and the speaker 70. This improves the structural stability of the electrical connector 50 and the electrical connection stability between the main control board 12 and the speaker 70.

[0065] 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 two adjacent stopper protrusions 115. The number of stopper protrusions 115 can be four, 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 pulled apart and breaking, and further improving the protection of the electrical connector 50.

[0066] 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.

[0067] 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.
