[0005] 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.

[0040] 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 watch to accurately identify the vehicle signal, which easily causes the failure of vehicle signal reception, and thus cannot meet the normal car key function requirements.

[0041] 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.

[0042] In the embodiment of the present utility model, Figures 1 to 3 As shown, the Figure 1 This is a structural schematic diagram of an embodiment of a head-type automobile key of the utility model; Figure 2 It is a structural explosion diagram of an embodiment of the head type automobile key of the utility model; Figure 3 It is a structural schematic diagram of an embodiment of a metal middle frame 10 in the present utility model.

[0043] The head-type automobile key includes: a shell, the shell has 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, and the communication port 11 connects the installation cavity with the outside of the shell; a communication element 20, the communication element 20 is installed in the installation cavity, and the communication element 20 is used to communicate with the elements outside the shell.

[0044] In this embodiment, the watch-type car key can be understood as loading the remote control function of the car key into the smart watch, so that the user can remotely control the car through the smart watch worn on the wrist. The watch-type car key can only have the function of remotely controlling the car, or it can also have other functions such as displaying time and information reminders.

[0045] The shell can provide a mounting cavity for the functional components of the head-type automobile key to protect it. The metal middle frame 10 is a part of the shell. The metal middle frame 10 is made of metal material, which can make the shell look more metallic and improve the overall structural strength of the shell to improve the anti-collision ability of the head-type automobile key.

[0046] The communication element 20 is used to realize wireless communication with the car so that the user can remotely control the car through the head-type car key; there are many forms of communication between the communication element 20 and the vehicle system, such as wireless communication through Bluetooth, 3G network, 4G network or 5G network, etc., which are not limited here.

[0047] For example, the communication element 20 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 20 includes components such as a receiving antenna, a microcontroller, a high-frequency transmitting circuit, a low-frequency receiving circuit, and a control switch.

[0048] Of course, the communication element 20 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.

[0049] The communication port 11 allows the communication signal between the communication element 20 and the car to avoid the metal middle frame 10 to enter and exit the shell, thereby avoiding the metal middle frame 10 from interfering with the signal transmission of the communication element 20. 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. The communication port 11 provides a signal transmission channel for the communication signal between the communication element 20 and the external element (such as the car's car system), so that the signal transmitted and / or received by the communication element 20 can interact with the external vehicle or accessories through the signal transmission channel, thereby greatly improving the strength of the signal transmission, ensuring that the head-type car key can correctly identify the vehicle signal to improve the remote control effect of the car.

[0050] For example, Figure 3 As shown, there are two communication ports 11, and the two communication ports 11 are arranged at intervals along the circumference of the metal middle frame 10. 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 20 to enter and exit can be increased, so as to further improve the communication effect between the communication element 20 and the car.

[0051] Specifically, Figure 3 and Figure 5 As shown, Figure 5 The figure is a projection diagram of an embodiment of the head-type automobile key of the utility model. The two communication ports 11 are located on opposite sides of the metal middle frame 10. The two communication ports 11 can be located at the 6 o'clock position and the 12 o'clock position of the head-type automobile key, respectively. In this way, no matter which end of the head-type automobile key faces the car, the communication signal of the communication element 20 can enter and exit the housing through the communication port 11 more quickly and timely. Of course, in some embodiments, the two communication ports 11 can also be located at the 3 o'clock position and the 9 o'clock position of the head-type automobile key, etc.

[0052] For example, Figure 2 As shown, the metal middle frame 10 includes a shell body and at least two mounting protrusions 12 arranged on the outer side wall of the shell body, and the mounting protrusions 12 are used to connect with the same end of the watch strap 30; the communication port 11 is located between the two mounting protrusions 12. After the two mounting protrusions 12 are connected to the same end of the watch strap 30, the watch strap 30 can hide and protect the communication port 11, so as to reduce the impact of the communication port 11 on the overall appearance of the watch head type car key, and prevent the position of the communication port 11 from being directly bumped, so as to improve the protection effect of the communication element 20 inside the communication port 11. In some embodiments, four mounting protrusions 12 are arranged on the metal middle frame 10, and two mounting protrusions 12 form a group. For the metal middle frame 10 arranged in a circular ring shape, the arc segment between the two mounting protrusions 12 in the same group is the inferior arc, and the arc segment between the two adjacent mounting protrusions 12 in different groups is the superior arc, and the communication port 11 is opened on the inferior arc segment. One end of the strap 30 is connected to one set of mounting protrusions 12 , and the other end is connected to the other set of mounting protrusions 12 .

[0053] In practical applications, such as Figure 4 As shown, Figure 4 It is a projection diagram of an embodiment of the metal middle frame 10 in the utility model. The communication port 11 extends along the circumference of the metal middle frame 10, and the width dimension d of the communication port 11 is greater than 1 / 3 of the height dimension h of the metal middle frame 10. In this way, it can be ensured that the communication port 11 has a sufficient size ratio in the height direction of the metal middle frame 10 to ensure the opening area of ​​the communication port 11 on the metal middle frame 10, thereby improving the transmission effect of the communication signal of the communication element 20.

[0054] The ratio of the length of the communication port 11 to the circumference of the metal middle frame 10 is set to 1 / 10-1 / 8, for example, it can be 1 / 10, 1 / 9 or 1 / 8; in this way, it can be ensured that the communication port 11 has a sufficient size ratio in the circumference direction of the metal middle frame 10 to ensure the opening area of ​​the communication port 11 on the metal middle frame 10, thereby improving the transmission effect of the communication signal of the communication element 20; at the same time, the opening area ratio of the communication port 11 is reasonably controlled to prevent the communication port 11 from affecting the structural strength of the metal middle frame 10 due to excessive opening area.

[0055] Exemplarily, the head-type automobile key further includes a non-metallic filler 80, and the non-metallic filler 80 is filled in the communication port 11. The non-metallic filler 80 can block the communication port 11, thereby preventing external dust or moisture from entering the installation cavity from the communication port 11, so as to effectively protect the communication element 20. The non-metallic filler 80 can be a rubber part, a plastic part, or a ceramic part, etc., which is not limited here. It can be understood that the non-metallic filler 80 will not have a shielding interference effect on the communication signal of the communication element 20, so as to ensure the normal operation of the communication element 20.

[0056] In another embodiment, the head-type automobile key further includes a non-metallic covering member, which is connected to the metal middle frame 10 or the communication port 11, and is used to cover the communication port 11. The non-metallic covering member can cover the communication port 11, thereby preventing external dust or moisture from entering the installation cavity from the communication port 11, so as to effectively protect the communication element 20. The non-metallic covering member can be a rubber member, a plastic member, or a ceramic member, etc., and is not limited here. It can be understood that the non-metallic covering member will not have a shielding interference effect on the communication signal of the communication element 20, so as to ensure the normal operation of the communication element 20.

[0057] Specifically, Figure 1 and Figure 2 As shown, the watch head type car key also includes a strap 30, and the two ends of the strap 30 are detachably connected to the outer side wall of the metal middle frame 10 respectively. The strap 30 can be worn by the user on the wrist to realize the wearing of the watch head type car key. The strap 30 can be a one-piece type or a two-piece type, which is not limited here. The tightness of the strap 30 can be adjusted to adapt to users with different wrist thicknesses. The strap 30 can be made of leather, TPU or silicone, or it can be made of metal. In combination with the above-mentioned embodiment of the mounting protrusion 12, the strap 30 can be rotatably connected to the mounting protrusion 12. The strap 30 is detachably connected to the metal middle frame 10, so that when the user does not want to wear the watch head type car key, the user can remove the strap 30 and carry the watch head type car key directly in a bag or pocket to adapt to the different usage scenarios of the user.

[0058] For example, Figure 3As shown, a key recess 13 is provided on the outer wall of the metal middle frame 10, and a key hole 14 connecting the installation cavity and the key recess 13 is provided at the bottom of the key recess 13. The key recess 13 is used for key installation, and a trigger switch adjacent to the installation hole is provided in the installation cavity. The trigger switch and the key are in contact through the key hole 14, so that the user can control the trigger switch by pressing the key to achieve control of other functions of the head-type car key. Since the key hole 14 connects the installation cavity with the outside world, when the key is a rubber key or a plastic key, the communication signal of the communication element 20 can also enter and exit the installation cavity through the key hole 14, that is, the key hole 14 can also provide a signal transmission channel for the communication element 20 that is not affected by the metal middle frame 10, thereby further improving the signal transmission effect of the communication element 20.

[0059] Specifically, Figure 2 As shown, the housing further includes a display panel 40 and a bottom shell 50, which are respectively arranged at the top and bottom of the metal middle frame 10, and the display panel 40, the bottom shell 50 and the metal middle frame 10 enclose the installation cavity. The display panel 40 has a touch interface, which can display functional information such as time and current state of the car, and can also allow users to touch and control the car key function.

[0060] Specifically, Figure 6 As shown, Figure 6 The structure of an embodiment of the head-type automobile key of the utility model is exploded. The communication element 20 is arranged adjacent to the communication port 11. The head-type automobile key may also include a main control board 70 installed in the installation cavity. The communication element 20 is arranged on the side of the main control board 70 facing the display panel 40. The distance between the main control board 70 and the display panel 40 is greater than the distance between the main control board 70 and the bottom shell 50. The communication element 20 is arranged directly opposite the communication port 11. Placing the communication element 20 adjacent to the communication port 11 can reduce obstacles between the communication element 20 and the communication port 11, so that the control signal emitted by the communication element 20 can be emitted from the housing through the communication port 11 more quickly, and the feedback signal of the external element can be received by the communication element 20 more quickly after entering the housing, thereby further reducing interference with the communication signal, so as to further improve the communication effect between the communication element 20 and the external element.

[0061] In practical applications, the display panel 40 includes a light-transmitting panel and a display screen connected to the inner side of the light-transmitting panel, and the periphery of the light-transmitting panel is sealed and connected to the metal middle frame 10 by a sealant. The light-transmitting panel can be a glass panel or a plastic panel, which is not limited here. The light-transmitting panel can protect the display screen, and the light-transmitting panel is sealed and connected to the metal middle frame 10, thereby preventing external moisture or dust from entering the installation cavity, so as to effectively protect the functional components in the installation cavity. Connecting the light-transmitting panel and the metal middle frame 10 by sealant can ensure that the light-transmitting panel will not be damaged due to excessive force during the connection process.

[0062] Exemplarily, a sealing groove is provided at the bottom of the metal middle frame 10, and a sealing member 60 is installed in the sealing groove, and the sealing member 60 is used to seal the connection between the bottom shell 50 and the metal middle frame 10. The sealing member 60 can be set as a rubber ring to improve the sealing effect of the connection between the bottom shell 50 and the metal middle frame 10.

[0063] Specifically, the head-type automobile key further includes a main control board 70 installed in the installation cavity, the bottom shell 50 is a plastic bottom shell 50, the communication element 20 is located on the side of the main control board 70 facing the display panel 40, and the communication port 11 is connected to the installation cavity between the main control board 70 and the display panel 40. The plastic bottom shell can reduce the overall weight of the shell to reduce the load when the user wears it. In addition, compared with metal, the plastic bottom shell 50 can also reduce the impact on the signal transmission of the communication element 20, thereby further ensuring the signal transmission effect of the communication element 20.

[0064] The utility model also provides an automobile assembly, which includes an automobile and a head-type automobile key. The specific structure of the head-type automobile key refers to the above embodiment. Since the automobile assembly adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here. The head-type automobile key is connected to the automobile for communication.

[0065] In the technical solution of the head-type car key of the utility model, the metal middle frame 10 can make the appearance of the shell more metallic and improve the overall structural strength of the shell to improve the anti-collision ability of the head-type car key. The communication port 11 provides a signal transmission channel for the communication signal between the communication element 20 and the external element (such as the car's vehicle system), so that the signal transmitted and / or received by the communication element 20 can interact with the external vehicle or accessories through the signal transmission channel, thereby greatly improving the strength of signal transmission, ensuring that the head-type car key can correctly identify the vehicle signal to improve the remote control effect of the car.

[0066] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
