[0030] 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 and antenna structure installed in the watch are used to receive and transmit the frequency signal of the vehicle system, so that the user can operate the car key function of the vehicle system through the watch. However, the existing smart watches usually place the antenna structure inside the watch, and the antenna structure is easily interfered by the display screen. Due to the high degree of interference of the antenna structure, the receiving signal performance of the antenna structure is reduced, making it impossible for the watch to accurately identify the vehicle signal, which easily causes the signal reception failure, and thus cannot meet the normal car key function requirements.

[0031] The utility model provides a head-type automobile key, aiming at solving the technical problem of how to improve the signal receiving effect of the head-type automobile key.

[0032] In the embodiment of the present utility model, Figure 1 and Figure 2 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 partial structural exploded view of an embodiment of a head-type automobile key of the utility model.

[0033] The head-type automobile key includes: a shell 10, the shell 10 includes a middle frame 11 and a display component 12 covered on the top of the middle frame 11, the display component 12 includes a display screen 13 and a light-transmitting sheet 14, the shell 10 is provided with a mounting cavity, the display screen 13 is arranged on the side of the light-transmitting sheet 14 facing the mounting cavity; an antenna structure 20, the antenna structure 20 is arranged on the side of the light-transmitting sheet 14 facing the display screen 13, and the projections of the antenna structure 20 and the display screen 13 on the light-transmitting sheet 14 are staggered with each other.

[0034] 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.

[0035] The housing 10 also includes a bottom shell 50 covering the bottom of the middle frame 11, and the display assembly 12, the middle frame 11 and the bottom shell 50 together enclose a mounting cavity. Among them, the light-transmitting sheet 14 can be a glass sheet, and the light-transmitting sheet 14 can protect the display screen 13. The functional components in the mounting cavity are all located in the covering area of ​​the light-transmitting sheet 14. The display screen 13 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 screen 13 contains a metal structure, which will have a shielding interference effect on the communication signal.

[0036] The antenna structure 20 is used to receive a communication signal from the vehicle to achieve wireless communication with the vehicle, so that the user can receive information fed back by the vehicle through the head-type vehicle key.

[0037] Since the projections of the antenna structure 20 and the display screen 13 on the light-transmitting sheet 14 are staggered, the antenna structure 20 can avoid the covering area of ​​the installation cavity by the display screen 13, so that the antenna structure 20 can bypass the display screen 13 to receive the signal passing through the light-transmitting sheet 14, so as to avoid the display screen 13 interfering with or shielding the process of the antenna structure 20 receiving the signal, thereby ensuring that the signal received by the antenna structure 20 can interact with the external vehicle or accessories, and ensure that the vehicle and the head-type car key can recognize each other's signals to improve the control effect of the car. In addition, staggering the projections of the antenna structure 20 and the display screen 13 on the light-transmitting sheet 14 can also avoid the antenna structure 20 blocking the display area of ​​the display screen 13, so as to ensure the external display effect of the display screen 13.

[0038] Specifically, Figure 2 As shown, a decorative layer 141 is provided at the periphery of the outer surface of the light-transmitting sheet 14, and the position of the antenna structure 20 corresponds to the decorative layer 141. The display screen 13 usually does not cover the top opening section of the middle frame 11, so a decorative layer 141 needs to be provided on the light-transmitting sheet 14 to cover the gap between the display screen 13 and the middle frame 11, so as to improve the appearance of the head-type car key. The position of the antenna structure 20 corresponds to the decorative layer 141, that is, the projection of the antenna structure 20 on the light-transmitting sheet 14 is located in the area where the decorative layer 141 is located, so that the antenna structure 20 can directly use the decorative layer 141 to achieve a hidden effect, preventing the antenna structure 20 on the inner side of the light-transmitting sheet 14 from being seen by the user from the outside, so as to improve the appearance integrity of the head-type car key.

[0039] The antenna structure 20 may be located around the display screen 13 , or may be arranged around the display screen 13 .

[0040] In practical applications, such as Figure 2 and Figure 3 As shown, Figure 3 This is a partial structural exploded view of another embodiment of the head-type automobile key of the utility model. The decorative layer 141 extends along the circumference of the light-transmitting sheet 14, and the antenna structure 20 extends along the circumference of the display screen 13. The antenna structure 20 is annularly arranged on the display screen 13, which can increase the volume of the antenna structure 20, thereby improving the signal receiving ability of the antenna structure 20 and ensuring the signal receiving effect. The decorative layer 141 is annularly arranged at the periphery of the light-transmitting panel to fully cover the antenna structure 20 around the display screen 13.

[0041] The antenna structure 20 may be fixedly connected to the light-transmitting sheet 14 , or may be fixedly connected to the middle frame 11 , which is not limited here.

The top of the mounting groove 15 passes through the top opening of the middle frame 11, so that the external signal can be directly received by the antenna structure 20 in the mounting groove 15 after passing through the light-transmitting sheet 14. The mounting groove 15 can increase the matching area between the antenna structure 20 and the middle frame 11, thereby improving the installation stability of the antenna structure 20 on the middle frame 11.

[0043] Specifically, Figure 3 and Figure 5 As shown, Figure 5 This is a partial cross-sectional exploded view of another embodiment of the head-type automobile key of the utility model. The inner side wall of the middle frame 11 is also provided with a positioning groove 16, which is located on the side of the installation groove 15 away from the light-transmitting sheet 14, and the positioning groove 16 passes through the installation groove 15; the antenna structure 20 includes an annular body 21 and a positioning portion 22 protruding from the annular body 21, and the positioning portion 22 cooperates with the positioning groove 16.

[0045] In practical applications, such as Figure 4 and Figure 5 As shown, Figure 4This is a partial cross-sectional exploded view of an embodiment of the dial-type automobile key of the utility model. The dial-type automobile key also includes a main control board 30 installed in the installation cavity, and the main control board 30 is located on the side of the display screen 13 away from the light-transmitting sheet; the positioning part 22 is set to a conductive material that is conductive with the annular body 21, and the number of the positioning parts 22 is two, and the two positioning parts 22 are spaced apart along the extension direction of the annular body 21, and the number and position of the positioning grooves 16 correspond to the positioning parts 22; two conductive structures 40 are installed on the main control board 30, and the two conductive structures 40 are in contact with and conductive with the two positioning parts 22 respectively.

[0046] The display screen 13 and the antenna structure 20 are both electrically connected to the main control board 30, and the main control board 30 can distribute power to the display screen 13 and the antenna structure 20, and convert the wireless signal received by the antenna structure 20 into a display signal and transmit it to the display screen 13 for display. The two positioning parts 22 can be used as a conductive positive electrode and a conductive negative electrode respectively, and the conductive structure 40 can be set as a conductive ejector pin, and the two conductive ejector pins are respectively abutted against the two positioning parts 22 to achieve electrical conduction between the two positioning parts 22 and the main control board 30; thereby, the effective utilization rate of the positioning parts 22 can be improved, and the power-on stability between the antenna structure 20 and the main control board 30 can be improved.

[0047] Exemplarily, the antenna structure 20 includes an insulating carrier and an antenna body covered on the surface of the insulating carrier. The insulating carrier may be a plastic carrier or a carrier of other materials, which is not limited here. The antenna body may be made of metal, and the antenna body may be covered on the surface of the insulating carrier by spraying or electroplating. The insulating carrier may improve the structural stability of the antenna structure 20.

[0048] Specifically, the periphery of the light-transmitting sheet 14 is sealed and connected to the middle frame 11 by sealant, so that external moisture or dust can be prevented from entering the installation cavity, so as to effectively protect the functional components in the installation cavity. The light-transmitting sheet 14 and the middle frame 11 are connected by sealant to ensure that the light-transmitting sheet 14 will not be damaged due to excessive force during the connection process. A glue overflow groove extending along the circumferential direction can be provided on the top of the middle frame 11, and the glue overflow groove can be filled with sealant. The periphery of the light-transmitting sheet 14 is covered in the glue overflow groove and bonded with the sealant.
