[0028] 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 element installed in the watch 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 watch. However, existing smart watches usually place the communication element inside the watch, and the communication element is easily interfered by the display panel. Due to the high degree of interference of the communication element, the receiving and transmitting signal performance of the communication element 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.

[0029] 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.

[0030] 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 exploded view of an embodiment of a head-type automobile key of the utility model; Figure 3 The utility model is a structural cross-sectional view of an embodiment of a head-type automobile key.

[0031] The watch head type car key includes: a shell 10, the shell 10 includes a middle frame 11 and a display panel 12 covering the top of the middle frame 11; a strap connector 20, the strap connector 20 is connected to the outer wall of the middle frame 11 for connection of a strap 50; and a communication element 30, the communication element 30 is at least partially installed on the strap connector 20 to avoid the covering area of ​​the display panel 12.

[0032] 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.

[0033] The housing 10 also includes a bottom shell covering the bottom of the middle frame 11. The display panel 12, the middle frame 11 and the bottom shell together enclose a mounting cavity 13. The functional components in the mounting cavity 13 are all located in the cover area of ​​the display panel 12. The display panel 12 has a touch interface, which can display functional information such as time and the current state of the car, and can also allow users to touch and control the car key function. The display panel 12 includes a metal structure, which will cause shielding interference to the communication signal.

[0034] The communication element 30 is used to realize wireless communication with the car so that the user can control the car through the head-type car key; there are many forms of communication between the communication element 30 and the vehicle system, such as wireless communication through Bluetooth, 3G network, 4G network or 5G network, etc., which are not limited here.

[0035] For example, the communication element 30 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 plan 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 30 includes components such as a receiving antenna, a microcontroller, a high-frequency transmitting circuit, a low-frequency receiving circuit, and a control switch.

[0036] Of course, the communication element 30 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 a quick response can be easily achieved, so that users wearing head-type car keys can automatically control the vehicle without feeling.

[0037] The communication element 30 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.

[0038] Since the strap connector 20 is connected to the outer wall of the middle frame 11, the strap connector 20 can avoid the covering area of ​​the inner cavity of the shell 10 by the display panel 12, and the communication element 30 is at least partially installed on the strap connector 20, so the communication element 30 can also at least partially avoid the covering area of ​​the display panel 12, so that the communication signal of the communication element 30 can bypass the display panel 12, so as to reduce the interference or shielding of the communication signal of the communication element 30 by the display panel 12, so that the signal transmitted and / or received by the communication element 30 can interact with the external vehicle or accessories, so as to ensure that the vehicle can recognize the signal of the watch head type car key, so as to improve the control effect of the car.

[0039] The communication element 30 can be installed inside the strap connector 20, or installed on the surface of the strap connector 20 or exposed on the strap connector 20. If the communication element 30 is installed on the surface of the strap connector 20 or exposed on the strap connector 20, the material of the strap connector 20 will not interfere with or shield the communication signal of the communication element 30, so the strap connector 20 can be a metal part or a non-metal part. If the communication element 30 is installed on the outer surface of the strap connector 20, the communication element 30 needs to be electrically connected to the main control board 40 in the installation cavity 13 through a conductor that penetrates the installation cavity 13.

[0040] Specifically, Figure 3 As shown, the strap connector 20 is a non-metallic part, and the strap connector 20 is provided with a receiving cavity 21, and the communication element 30 is installed in the receiving cavity 21; in this way, the strap connector 20 can play a role in hiding and protecting the communication element 30, so as to improve the appearance integrity of the head-type car key and improve the protection effect of the communication element 30. The communication element 30 is installed inside the strap connector 20, so the strap connector 20 needs to be set as a non-metallic part to prevent shielding interference to the communication signal of the communication element 30.

[0041] The receiving cavity 21 can be connected to the installation cavity 13 or isolated from the installation cavity 13, which is not limited here. If the receiving cavity 21 is isolated from the installation cavity 13, the communication element 30 needs to be electrically connected to the main control board 40 in the installation cavity 13 through a conductor penetrating the installation cavity 13.

[0042] For example, Figure 3 As shown, the middle frame 11 and the display panel 12 are arranged to form an installation cavity 13, and the head-type automobile key also includes a main control board 40 installed in the installation cavity 13. The middle frame 11 is provided with a wire passing port connected to the installation cavity 13, and the receiving cavity 21 is provided with an opening docking with the wire passing port, and the communication element 30 is electrically connected to the main control board 40.

[0043] The main control board 40 is used to distribute electrical energy to the communication element 30 and transmit control signals so that the communication element 30 can operate or standby according to the user's control instructions. The electrical connection between the main control board 40 and the communication element 30 can be direct contact energization or energization through a conductor. For example, the communication element 30 can be partially extended into the installation cavity 13 to be directly connected to the main control board 40 for power. Or the main control board 40 can be partially extended into the receiving cavity 21 to be directly connected to the communication element 30 for power. Of course, the communication element 30 can also be completely located in the receiving cavity 21 and electrically connected to the main control board 40 through conductors such as wires.

[0044] The middle frame 11 may be a metal part or a non-metal part, which is not limited here.

[0045] Specifically, the middle frame 11 is a non-metallic part, and the middle frame 11 and the strap connector 20 are integrally formed. The material of the middle frame 11 and the strap connector 20 can be plastic or ceramic, which is not limited here. The middle frame 11 and the strap connector 20 can be made of the same material, so that the middle frame 11 and the strap connector 20 can be integrally formed by an injection molding process, that is, the middle frame 11 and the strap connector 20 are directly connected together during the injection molding process, so that the processing and connection process of the middle frame 11 and the strap connector 20 can be simplified, and the production and processing efficiency of the middle frame 11 and the strap connector 20 can be improved.

[0046] In practical applications, the material of the middle frame 11 and the strap connector 20 includes at least one of ceramic, plastic, carbon fiber or thermoplastic polyurethane (TPU).

[0047] For example, Figure 3 As shown, there are two strap connectors 20 , which are respectively located on opposite sides of the middle frame 11 , and both strap connectors 20 have reserved accommodating cavities 21 , and the communication element 30 is installed in one of the accommodating cavities 21 .

[0048] The two strap connectors 20 are used to connect the two ends of the strap 50 respectively, and the two strap connectors 20 are both reserved with a receiving cavity 21, so that when assembling the communication element 30 and the main control board 40, the communication element 30 can be installed in any receiving cavity 21 first, and then the position of the main control board 40 is determined according to the position of the communication element 30. Or the main control board 40 is installed first, and then the communication element 30 is installed in the receiving cavity 21 closer to the main control board 40 according to the actual position of the main board. In this way, the assembly process and connection process of the communication element 30 can be made simpler and more convenient, so as to improve the assembly efficiency of the communication element 30.

[0049] In another embodiment, the middle frame 11 includes a non-metallic inner frame and a metal outer frame, the non-metallic inner frame is arranged in a ring shape as a whole, and the metal outer frame includes a first frame portion and a second frame portion, the first frame portion and the second frame portion are connected to the outer wall surface of the non-metallic inner frame, and at least one avoidance opening is formed between the first frame portion and the second frame portion, and the strap connector 20 is arranged at the avoidance opening and connected to the non-metallic inner frame.

[0050] The middle frame 11 is a composite middle frame 11, wherein the non-metal inner frame can surround the installation cavity 13, and the specific material of the non-metal inner frame can be plastic, silicone or ceramic. The metal outer frame can make the appearance of the shell 10 more metallic and improve the overall structural strength of the shell 10, so as to improve the anti-collision ability of the head-type car key.

[0051] The metal outer frame and the non-metallic inner frame can be connected by an injection molding process, or they can be processed and formed separately and then connected together, which is not limited here. The first frame portion and the second frame portion both extend along the circumference of the non-metallic inner frame. The first frame portion and the second frame portion can be connected to each other or can be separately arranged; that is, the end of the first frame portion away from the avoidance opening and the end of the second frame portion away from the avoidance opening can be connected or disconnected, which is not limited here. In combination with the above-mentioned two embodiments of the strap connectors 20, the number of the avoidance openings is two, one of which is formed between one end of the first frame portion and one end of the second frame portion, and the other avoidance opening is formed between the other end of the first frame portion and the other end of the second frame portion. The two strap connectors 20 are respectively arranged at the two avoidance openings and are both connected to the non-metallic inner frame.

[0052] For example, Figure 1 and Figure 2 As shown, the watch head type car key also includes a watch strap 50, and the two ends of the watch strap 50 are rotatably connected to the two watch strap connectors 20 respectively. The watch strap 50 can be worn on the wrist of the user to realize the wearing of the watch head type car key.
