[0037] 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 operate the car key through the smart watch. The communication components installed in the watch receive and transmit the frequency signal of the car system, so that the user can operate the car key function of the car system through the watch. However, existing smart watches usually place the communication components inside the watch. The communication components are easily interfered by the metal shell of the watch and the internal electronic components. Due to the high degree of interference of the communication components, the receiving and transmitting signal performance of the communication components is reduced, making it impossible for the vehicle to accurately identify the watch signal, which easily causes the vehicle signal reception failure, and thus cannot meet the normal car key function requirements.

[0038] The utility model provides 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.

[0039] In the embodiment of the present utility model, Figures 1 to 3 As shown, Figure 1 This is a structural schematic diagram of an embodiment of a head-type automobile key of the utility model; Figure 2 This is a structural cross-sectional view of an embodiment of a head-type automobile key of the utility model; Figure 3 for Figure 2 A partial enlarged view of point A in the middle.

[0040] The watch head type automobile key includes: a shell, the shell is provided with an installation cavity, the shell includes a metal middle frame 10 which is arranged in an overall ring shape, and at least one communication port 11 is opened on the side wall of the metal middle frame 10; a strap 20, the two ends of the strap 20 are respectively connected to the outer side walls of the metal middle frame 10, and the end of the strap 20 connected to the metal middle frame 10 blocks the communication port 11.

[0041] In this embodiment, the watch-type car key can be understood as loading the car control function of the car key into the smart watch, so that the user can control the car by wearing the smart watch on the wrist. The watch-type car key can only have the function of controlling the car, or it can also have other functions such as displaying time and information reminder.

[0042] The housing of the keypad also includes a display panel and a bottom housing, which are mounted on the top and bottom of the metal middle frame 10, respectively. The display panel, the metal middle frame 10 and the bottom housing together form a mounting cavity. The mounting cavity can accommodate and protect functional components such as the main control board 50. The metal middle frame 10 can make the appearance of the housing more metallic and improve the overall structural strength of the housing, so as to improve the anti-collision ability of the keypad-type automobile key.

[0043] The strap 20 can be worn on the wrist of the user to realize the wearing of the watch head type car key. The strap 20 is a non-metallic part, and can be made of leather, TPU or silicone. The strap 20 can be one-piece or two-piece.

[0044] The watch-type car key also includes a communication element 40, which is used to realize wireless communication with the car so that the user can control the car through the watch-type car key; there are many forms of communication between the communication element 40 and the vehicle system, such as wireless communication through Bluetooth, 3G network, 4G network or 5G network, which is not limited here.

[0045] For example, the communication element 40 can be part of a smart key system, a smart key system (PASSIVE KEYLESS ENTER), referred to as PKE, which uses RFID wireless radio frequency technology and a vehicle identity code recognition system, applies a development solution of a miniaturized, low-power radio frequency antenna, integrates a remote control system and a keyless system, and uses traditional vehicle circuit protection to achieve a dual radio frequency system and dual anti-theft protection. In the PKE system, the car serves as a base station and the head-type car key serves as a transponder to achieve two-way communication. The 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.

[0046] Of course, the communication element 40 can also be an element in ultra-wideband wireless carrier communication technology. Ultra-wideband (UltraWide Band) is referred to as UWB, which adopts new ultra-wideband wireless technology that is very different from traditional communication technology. It sends and receives extremely narrow pulses of nanoseconds or below to transmit data to the vehicle, has a bandwidth of 3.1 to 10.6 GHz, and is not easily interfered by other signals. Through the interaction between the UWB of the head-type car key and the vehicle UWB, the positioning algorithm characteristics can be used to identify the centimeter-level distance from the vehicle, and quickly respond easily, so that users wearing head-type car keys can automatically control the car without feeling.

[0047] The communication element 40 may be an element that can send out signals by itself, or may be a signal amplifier that amplifies the signal strength after receiving the signal and then sends it out, and there is no limitation here.

[0048] The communication element 40 can be installed in the installation cavity or on the watch strap 20, without limitation. When the communication element 40 is installed in the installation cavity, the communication port 11 is used for communication signals to enter and exit the installation cavity; when the communication element 40 is installed on the watch strap 20, the communication port 11 is used for the conductive structure routing between the main control board 50 and the communication element 40.

[0049] In one embodiment, the communication element 40 is installed in the installation cavity, and the communication element 40 is used to communicate with the elements outside the shell through the communication port 11. The communication port 11 allows the communication signal between the communication element 40 and the car to avoid the metal middle frame 10 to enter and exit the shell, thereby preventing the metal middle frame 10 from interfering with the signal transmission of the communication element 40. The number of communication ports 11 can be one, or two or more, and there is no restriction here. The shape of the communication port 11 can be a rectangle, or some regular shapes such as a triangle, a circle, an ellipse, or some irregular shapes, etc., and there is no restriction here. The width of the communication port 11 is less than the height of the metal middle frame 10, and the length of the communication port 11 is less than the circumference of the metal middle frame 10; the specific size of the communication port 11 is not limited here.

[0050] The communication port 11 provides a signal transmission channel for the communication signal between the communication element 40 and an external element (such as the vehicle's on-board system), so that the signal transmitted and / or received by the communication element 40 can interact with the external vehicle or accessories through the signal transmission channel, thereby greatly improving the strength of signal transmission and ensuring that the head-type car key can correctly identify the vehicle signal to improve the control effect of the car.

[0051] By blocking the communication port 11 with the end of the strap 20 , external moisture or dust can be prevented from entering the installation cavity through the communication port 11 , thereby hiding and protecting functional components such as the main control board 50 in the installation cavity.

[0052] Specifically, there are two communication ports 11, which are arranged at intervals along the circumference of the metal middle frame 10, and the two ends of the strap 20 respectively block the two communication ports 11. By setting the number of communication ports 11 to two, the positions on the metal middle frame 10 for the communication signal of the communication element 40 to enter and exit can be increased, so as to further improve the communication effect between the communication element 40 and the car.

[0053] If the communication element 40 is mounted on the strap 20 , it may be directly mounted on the strap 20 , or indirectly mounted on the strap 20 via an intermediate structure.

[0054] In another embodiment, if Figure 4 As shown, Figure 4 The structure of an embodiment of the watch head type automobile key of the utility model is exploded. The watch head type automobile key further includes a main control board 50, a communication element 40 and an electrical connector 60, wherein the main control board 50 is installed in the installation cavity, the communication element 40 is installed in the watch strap 20, and the electrical connector 60 extends along the watch strap 20, wherein one end of the electrical connector 60 is electrically connected to the communication element 40, and the other end of the electrical connector 60 extends from the communication port 11 into the installation cavity and is electrically connected to the main control board 50.

[0055] The main control board 50 can distribute power and transmit control signals to the communication element 40 through the electrical connector 60, so that the communication element 40 can operate or standby according to the control instructions of the user.

[0056] The electrical connector 60 may be a conductive wire harness or a flexible printed circuit (FPC), which is not limited here. The electrical connector 60 may extend along the surface of the strap 20 or extend inside the strap 20, which is not limited here. It is understood that the electrical connector 60 is flexible and bendable so that the electrical connector 60 can bend and deform along with the strap 20. Compared with the wire, the flexible printed circuit board has a larger width, better toughness, and is less likely to break, which can improve the structural stability of the electrical connector 60. A high-frequency circuit can also be integrated on the flexible printed circuit board, so that the communication element 40 can have both high-frequency signal transmission function and low-frequency signal transmission function.

[0057] The electrical connector 60 is directly inserted into the installation cavity through the communication port 11 and connected to the main control board 50, so that the electrical connector 60 and the main control board 50 can be directly powered without adding an intermediate conductor, thereby simplifying the power supply method of the electrical connector 60 and the main control board 50 and improving the power supply stability.

[0058] Since the communication element 40 is installed on the watch strap 20, that is, outside the installation cavity, it can prevent the metal and screen and other electronic components of the shell from interfering with or shielding the communication signal of the communication element 40, so that the signal 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 the vehicle signal to improve the control effect of the car.

[0059] By blocking the communication port 11 through the end of the strap 20, external moisture or dust can be prevented from entering the installation cavity through the communication port 11, and the electrical connector 60 passing through the communication port 11 can be protected to ensure the stability of the electrical connection between the communication element 40 on the strap 20 and the communication element 40 in the installation cavity.

[0060] In another embodiment, the watch head type car key also includes a main control board 50, a communication element 40, a clasp 70 and an electrical connector 60, the main control board 50 is installed in the installation cavity, the clasp 70 is connected to the strap 20, and the clasp 70 is used to adjust the wearing length of the strap 20; the communication element 40 is installed on the clasp 70, the electrical connector 60 extends along the strap 20, one end of the electrical connector 60 is electrically connected to the communication element 40, and the other end extends from the communication port 11 into the installation cavity and is electrically connected to the main control board 50.

[0061] The buckle 70 is used for the user to adjust the wearing length of the strap 20, so that the user can adjust the tightness of the strap 20 according to the thickness of the wrist. Of course, for a two-section strap 20, the buckle 70 is also used to connect or unfasten the two sections of the strap 20, and the user can adjust the wearing length of the strap 20 while connecting the two sections of the strap 20. Depending on the specific form, the buckle 70 may include a hook buckle, a concealed buckle, a butterfly buckle, a belt snap buckle, a folding safety buckle, a folding buckle or a pin buckle.

[0062] The clasp 70 can be a metal part or a non-metal part. For example, if the communication element 40 is installed on the surface of the clasp 70 or exposed on the clasp 70, whether the clasp 70 is a metal part or a non-metal part, it will not shield or interfere with the signal of the communication element 40. Since the communication element 40 is installed on the clasp 70, that is, outside the installation cavity, it can avoid the metal of the shell and the electronic components such as the screen from interfering or shielding the communication signal of the communication element 40, so that the signal transmitted and / or received by the communication element 40 can interact with the external vehicle or accessories, ensuring that the vehicle can recognize the signal of the head-type car key to improve the control effect of the car.

[0063] The communication element 40 can be installed on the outer surface of the strap 20 or the buckle 70, or can be installed inside the strap 20 or the buckle 70, which is not limited here.

[0064] Specifically, Figure 5 and Figure 6 As shown, Figure 5 This is a cross-sectional exploded view of an embodiment of a head-type automobile key of the utility model; Figure 6 for Figure 5 A partial enlarged view of point B in the middle.

[0065] The strap 20 or the buckle 70 is provided with a receiving cavity 23, and the communication element 40 is installed in the receiving cavity 23; the strap 20 is provided with a wiring channel 24, one end of the wiring channel 24 is connected to the receiving cavity 23, and the other end passes through the strap 20 to block one end of the communication port 11, and the electrical connector 60 is arranged in the wiring channel 24.

[0066] The communication element 40 is installed in the receiving cavity 23, which can hide and protect the communication element 40, thereby improving the appearance integrity of the strap 20 or the buckle 70, and improving the protection effect of the communication element 40. The wiring channel 24 extends along the length direction of the strap 20, and the portion of the electrical connector 60 extending along the strap 20 is located in the wiring channel 24, so that the electrical connector 60 can be hidden and protected, thereby improving the appearance integrity of the strap 20, and improving the protection effect of the electrical connector 60.

[0067] There are many specific ways for the strap 20 to block the communication port 11. The end of the strap 20 may be directly inserted into the communication port 11, or the end of the strap 20 may just cover the communication port 11. There is no limitation here.

[0068] For example, Figures 2 to 6 As shown, the outer wall of the metal middle frame 10 is provided with an assembly groove 12, and the communication port 11 is opened at the bottom of the assembly groove 12; the end of the strap 20 is provided with an assembly boss 21, and the assembly boss 21 cooperates with the assembly groove 12.

[0069] The assembly boss 21 is convexly arranged at one end of the watchband 20 close to the outer shell, and the assembly boss 21 cooperates with the assembly groove 12 to realize the fixed connection between the watchband 20 and the outer shell. In combination with the above-mentioned embodiment of the wiring channel 24, the wiring channel 24 can pass through the end wall of the assembly boss 21, so that the electrical connector 60 can pass through the assembly boss 21 and then extend into the installation cavity from the communication port 11. In this way, the part of the electrical connector 60 exposed to the communication port 11 can be wrapped and hidden to improve the protection effect of the electrical connector 60 and prevent the electrical connector 60 from contacting the user. In addition, the assembly boss 21 can also block the communication port 11 to prevent external moisture and dust from entering the installation cavity from the communication port 11, so as to improve the protection effect of the components in the installation cavity. The assembly boss 21 can be integrally formed with the watchband 20 to simplify the processing and forming method of the assembly boss 21.

[0070] Specifically, Figure 6 As shown, the side wall of the assembly boss 21 is convexly provided with a sealing rib 211, and the sealing rib 211 extends along the circumference of the communication port 11, and the assembly boss 21 and the assembly groove 12 are sealed and matched through the sealing rib 211. The sealing rib 211 can be convexly provided on the peripheral wall of the assembly boss 21, and can also be convexly provided on the end wall of the assembly boss 21, and there is no restriction here. It is only necessary to satisfy that the sealing rib 211 can be arranged around the communication port 11 and abut against the groove wall or groove bottom of the assembly groove 12. The sealing rib 211 can seal the gap between the assembly boss 21 and the assembly groove 12 to further prevent external dust and moisture from entering the installation cavity from the communication port 11, thereby further improving the protection effect of the components in the installation cavity. The sealing rib 211 can be integrally formed with the assembly boss 21 to simplify the processing and forming method of the sealing rib 211.

[0071] The end of the strap 20 can be directly connected to the housing, or indirectly connected via an intermediate piece, which is not limited here.

[0072] For example, Figures 2 to 6As shown, the watch head type car key also includes a connector 30, and the connector 30 includes a first connector 31 and a second connector 32 connected to each other, the first connector 31 is connected to the end of the watch strap 20, and the second connector 32 is filled in the communication port 11 and connected to the metal middle frame 10. The connector 30 is an integrally formed part, that is, the first connector 31 and the second connector 32 are integrally formed. The second connector 32 can completely block the filling port by filling the communication port 11, thereby improving the blocking effect of the communication port 11. Connecting the watch strap 20 to the metal middle frame 10 through the connector 30 can improve the connection strength between the watch strap 20 and the metal middle frame 10.

[0073] Specifically, Figures 2 to 8 As shown, Figure 7 This is a cross-sectional exploded view of another embodiment of the head-type automobile key of the utility model; Figure 8 for Figure 7 A partial enlarged view of point C in the middle.

[0074] The end of the strap 20 is provided with a connection groove 22, and the first connection part 31 is embedded in the connection groove 22. In this way, the matching area between the first connection part 31 and the strap 20 can be increased to improve the connection stability between the first connection part 31 and the strap 20. The thickness of the first connection part 31 can decrease from the side close to the second connection part 32 to the side away from the second connection part 32, so that the force from the first connection part 31 when the end of the strap 20 is bent can produce a gradual transition effect, so as to avoid the strap 20 being damaged due to local concentrated force.

[0075] In practical applications, such as Figure 7 and Figure 8 As shown, a limiting column 221 is convexly disposed in the connection groove 22, and a limiting hole 311 is provided in the first connection portion 31, and the limiting column 221 is passed through the limiting hole 311. The limiting column 221 can limit the first connection portion 31 in the connection groove 22 to prevent the first connection portion 31 from easily detaching from the connection groove 22, thereby improving the connection stability between the first connection portion 31 and the connection groove 22.

[0076] In another embodiment, the width of the first connection portion 31 near the slot opening of the connection slot 22 is greater than the slot opening width of the connection slot 22 to limit the first connection portion 31 from detaching from the connection slot 22, thereby also improving the connection stability between the first connection portion 31 and the connection slot 22.

[0077] For example, Figure 7 and Figure 8As shown, the second connection part 32 is provided with a connection lug 321, the connection lug 321 extends into the installation cavity, and the connection lug 321 is provided with a connection hole 322; the inner wall surface of the middle frame is provided with a connection boss 13, the connection boss 13 is provided with a fixing hole 131 corresponding to the connection hole 322, and the fixing hole 131 is connected to the connection hole 322 by a fastener. The connection boss 13 is adjacent to the communication port 11, and the connection lug 321 is provided on the side of the second connection part 32 away from the first connection part 31. After the second connection part 32 is filled in the communication port 11, the connection lug 321 abuts against the connection boss 13, and the fixing hole 131 is aligned with the connection hole 322, so that the fastener connects the connection lug 321 and the connection boss 13 in series, so as to realize the fixed connection between the connection lug 321 and the connection boss 13. The fixing hole 131 may be set as a threaded hole, and the fastener may be set as a screw. The fastener and the fixing hole 131 are threadedly matched to simplify the assembly process of the fastener.

[0078] Specifically, the connector 30 has elastic deformation capability, so that the connector 30 can be deformed along with the bending deformation of the strap 20, reducing the obstruction of the connector 30 to the bending deformation process of the end of the strap 20, so as to ensure the wearing convenience and comfort of the strap 20. The material of the connector 30 can be plastic, rubber or TPU. In combination with the above-mentioned embodiments of the limiting column 221 and the limiting hole 311, the connector 30 and the strap 20 can be connected by a secondary injection molding process to simplify the connection process of the connector 30 and the strap 20.

[0079] In practical applications, the deformation resistance of the connector 30 is greater than that of the strap 20, that is, the deformation amplitude of the connector 30 is smaller than that of the strap 20 under the same force, so the bending deformation amplitude of the strap 20 near the communication port 11 will be limited. In combination with the above-mentioned embodiment of the electrical connector 60, the deformation amplitude of the electrical connector 60 at the communication port 11 will also be reduced accordingly, so that the electrical connector 60 can be prevented from being repeatedly bent to a large extent, thereby preventing the electrical connector 60 from being easily broken at the communication port 11, resulting in poor power supply between the main control board 50 and the communication element 40, so as to improve the structural stability of the electrical connector 60 and improve the power supply stability between the main control board 50 and the communication element 40.

[0080] For example, Figure 4As shown, at least two limiting protrusions 14 are convexly arranged on the outer side wall of the middle frame, and the at least two limiting protrusions 14 are arranged at intervals along the circumference of the middle frame, and one end of the strap 20 connected to the middle frame is located between two adjacent limiting protrusions 14. The number of limiting protrusions 14 can be four, wherein every two adjacent limiting protrusions 14 form a group, and the two groups of limiting protrusions 14 are respectively used to limit the two ends of the strap 20. The two adjacent limiting protrusions 14 are located on both sides of the width direction of the strap 20, so as to limit the deformation of the ends of the strap 20 along the width direction, so as to reduce the deformation of the electrical connector 60 along the width direction of the strap 20, so as to further prevent the electrical connector 60 from being pulled and broken, so as to further improve the protection effect of the electrical connector 60.
