[0033] 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 transmission, and thus cannot meet the normal car key function requirements.

[0034] 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.

[0035] 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 It is a structural schematic diagram of an embodiment of a middle frame assembly in the utility model.

[0036] The head-type automobile key includes: a shell, the shell has an installation cavity, the shell includes a middle frame assembly, the middle frame assembly includes a non-metallic inner frame 10 and a metal outer frame, the non-metallic inner frame 10 is arranged in a ring shape as a whole, the metal outer frame includes a first frame portion 21 and a second frame portion 22, the first frame portion 21 and the second frame portion 22 are connected to the outer wall surface of the non-metallic inner frame 10, and at least one completely disconnected communication port 23 is formed between the first frame portion 21 and the second frame portion 22; a communication element 30, the communication element 30 is installed in the installation cavity, and the communication element 30 is used to communicate with elements outside the shell.

[0037] 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.

[0038] The shell can provide a mounting cavity for the functional components of the head-type car key to protect it. The middle frame assembly is a part of the shell, and the middle frame assembly is a composite middle frame, wherein the non-metallic inner frame 10 can surround the mounting cavity, and the specific material of the non-metallic inner frame 10 can be plastic, TPU or silicone. The metal outer frame 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.

[0039] 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 3020 and the vehicle system, such as wireless communication through Bluetooth, 3G network, 4G network or 5G network, etc., which are not limited here.

[0040] For example, the communication element 30 can be part of a smart key system, the smart key system (PASSIVE KEYLESS ENTER), referred to as PKE, which uses RFID wireless radio frequency technology and vehicle identity coding recognition system, applies a development plan of miniaturized, low-power radio frequency antenna, integrates the remote control system and the keyless system, and uses traditional vehicle circuit protection to achieve dual radio frequency systems and dual anti-theft protection. In the PKE system, the car acts as a base station and the head-type car key acts 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.

[0041] 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 uses new ultra-wideband wireless technology that is very different from traditional communication technology. It sends and receives extremely narrow pulses with nanoseconds or less 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.

[0042] The metal outer frame and the non-metal inner frame 10 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 21 and the second frame portion 22 both extend along the circumference of the non-metal inner frame 10. The first frame portion 21 and the second frame portion 22 can be connected to each other or can be set separately; that is, the end of the first frame portion 21 away from the communication port 23 and the end of the second frame portion 22 away from the communication port 23 can be connected or disconnected, which is not limited here.

[0043] The non-metal inner frame 10 has substantially no shielding interference effect on the communication signal between the communication element 30 and the car, and the communication port 23 allows the communication signal between the communication element 30 and the car to enter and exit the housing without the metal outer frame, thereby preventing the metal outer frame from interfering with the signal transmission of the communication element 30. The number of the communication ports 23 may be one, or two or more, and is not limited here.

[0044] The completely disconnected communication port 23 formed by the metal frame can provide a signal transmission channel for the communication signal between the communication element 30 and an external element (such as the vehicle's on-board system), so that the signal transmitted and / or received by the communication element 30 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.

[0045] Specifically, Figure 4 As shown, Figure 4 The figure is a projection diagram of an embodiment of the middle frame assembly of the utility model. There are two communication ports 23, one of which is formed between one end of the first frame portion 21 and one end of the second frame portion 22, and the other communication port 23 is formed between the other end of the first frame portion 21 and the other end of the second frame portion 22.

[0046] The first frame portion 21 has a first end and a second end in the extending direction, the second frame portion 22 has a third end and a fourth end in the extending direction, the first end is close to the third end, the second end is close to the fourth end, a first communication port 23 is formed between the first end and the third end, and a second communication port 23 is formed between the second end and the fourth end. By setting the number of the communication ports 23 to two, the positions on the metal outer frame that can be used for the communication signal of the communication element 30 to enter and exit can be increased, so as to further improve the communication effect between the communication element 30 and the car.

[0047] The extension dimensions of the first frame portion 21 and the second frame portion 22 may be the same or different, which is not limited here.

[0048] In practical applications, such as Figure 4 As shown, the two communication ports 23 are located on opposite sides of the non-metallic inner frame 10, that is, the extension size of the first frame portion 21 and the second frame portion 22 is the same. The two communication ports 23 can be located at the 6 o'clock position and the 12 o'clock position of the head-type car key, respectively. In this way, no matter which end of the head-type car key faces the car, the communication signal of the communication element 30 can enter and exit the housing through the communication port 23 faster and more timely. Of course, in some embodiments, the two communication ports 23 can also be located at the 3 o'clock position and the 9 o'clock position of the head-type car key, etc.

[0049] For example, Figure 3 and Figure 4 As shown, a first mounting protrusion 211 is provided at one end of the first frame portion 21 close to the communication port 23, and a second mounting protrusion 221 is provided at one end of the second frame portion 22 close to the communication port 23. The first mounting protrusion 211 and the second mounting protrusion 221 are opposite to each other across the communication port 23, and the first mounting protrusion 211 and the second mounting protrusion 221 are used to be connected to the same end of the watch strap.

[0050] After the first mounting protrusion 211 and the second mounting protrusion 221 are connected to the same end of the watch strap, the watch strap can hide and protect the area of ​​the non-metallic inner frame 10 exposed at the communication port 23, so as to reduce the impact of the area of ​​the non-metallic inner frame 10 exposed at the communication port 23 on the overall appearance of the watch head type automobile key, and prevent the area of ​​the non-metallic inner frame 10 exposed at the communication port 23 from being directly bumped.

[0051] In combination with the above-mentioned two embodiments of the communication ports 23, the first end and the second end of the first frame portion 21 are both provided with a first mounting protrusion 211, and the third end and the fourth end of the second frame portion 22 are both provided with a second mounting protrusion 221, the first mounting protrusion 211 at the first end and the second mounting protrusion 221 at the third end are a group, and the first mounting protrusion 211 at the second end and the second mounting protrusion 221 at the fourth end are a group, one end of the strap is connected to one group of adjacent first mounting protrusions 211 and second mounting protrusions 221, and the other end of the strap is connected to another group of adjacent first mounting protrusions 211 and second mounting protrusions 221.

[0052] A first axial hole is provided on a side of the first mounting protrusion 211 facing the second mounting protrusion 221, and a second axial hole is provided on a side of the second mounting protrusion 221 facing the first mounting protrusion 211. A connecting shaft may be provided at the end of the watch strap, and the two ends of the connecting shaft respectively cooperate with the first axial hole and the second axial hole to realize a rotatable connection between the watch strap and the first mounting protrusion 211 and the first mounting protrusion 221.

[0053] Specifically, the watch head type car key also includes a watch strap, and the two ends of the watch strap are detachably connected to the metal outer frame. The watch strap can be worn by the user on the wrist to realize the wearing of the watch head type car key. The watch strap can be a one-piece type or a two-piece type, which is not limited here. The tightness of the watch strap can be adjusted to adapt to users with different wrist thicknesses. The watch strap can be made of leather, TPU or silicone, or it can be made of metal. In combination with the above-mentioned embodiment of the first mounting protrusion 211 and the second mounting protrusion 221, the watch strap can be rotatably connected to the first mounting protrusion 211 and the second mounting protrusion 221. The watch strap is detachably connected to the metal outer frame, so that when the user does not want to wear the watch head type car key, the watch head type car key can be directly carried in a bag or pocket after removing the watch strap to meet the different usage scenario requirements of the user.

[0054] For example, Figure 4 and Figure 5 As shown, Figure 5 This is a structural exploded view of an embodiment of the middle frame assembly in the utility model. The outer wall surface of the non-metallic inner frame 10 is provided with a thickened portion 11 in the area corresponding to the communication port 23. The thickened portion 11 makes the thickness of the non-metallic inner frame 10 corresponding to the communication port 23 greater than the thickness of other parts, so that the structural strength of the non-metallic inner frame 10 corresponding to the communication port 23 can be effectively improved to prevent the area of ​​the non-metallic inner frame 10 exposed to the communication port 23 from being easily damaged or deformed when bumped, thereby improving the structural stability of the middle frame assembly.

[0055] Specifically, Figure 5As shown, the non-metal inner frame 10 is provided with an inner button hole 13, and the metal outer frame is provided with an outer button hole 25 corresponding to the inner button hole 13. The outer button hole 25 can be used for button installation, and a trigger switch adjacent to the inner button hole 13 is provided in the installation cavity. The trigger switch and the button are in contact through the inner button hole 13 and the outer button hole 25, so that the user can control the trigger switch by pressing the button to achieve control of other functions of the head-type car key. Since the inner button hole 13 and the outer button hole 25 connect the installation cavity with the outside, when the button is a rubber button or a plastic button, the communication signal of the communication element 30 can also enter and exit the installation cavity through the inner button hole 13 and the outer button hole 25, that is, the inner button hole 13 and the outer button hole 25 can also provide the communication element 30 with a signal transmission channel that is not affected by the metal outer frame, thereby further improving the signal transmission effect of the communication element 30.

[0056] In practical applications, such as Figure 5 As shown, a limiting protrusion 12 is convexly provided on the outer wall surface of the non-metallic inner frame 10, and a limiting groove 24 is provided on the inner wall surface of the first frame portion 21 and / or the second frame portion 22, and the limiting protrusion 12 cooperates with the limiting groove 24. In this way, the cooperation stability between the first frame portion 21 and / or the second frame portion 22 and the non-metallic inner frame 10 can be improved, and the first frame portion 21 and / or the second frame portion 22 can be prevented from easily detaching from the non-metallic inner frame 10, thereby improving the overall structural stability of the middle frame assembly.

[0057] For example, 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 non-metallic inner frame 10, and the display panel 40, the bottom shell 50 and the non-metallic inner 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.

[0058] Specifically, Figure 2 As shown, the communication element 30 is arranged adjacent to the communication port 23. The head-type automobile key may further include a main control board 60 installed in the installation cavity, and the communication element 30 is arranged on the side of the main control board 60 facing the display panel 40, and the communication element 30 is arranged directly opposite to the communication port 23. Placing the communication element 30 adjacent to the communication port 23 can reduce obstacles between the communication element 30 and the communication port 23, so that the communication signal emitted by the communication element 30 can be emitted out of the housing through the communication port 23 more quickly, and the feedback signal of the external element can be received by the communication element 30 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 30 and the external element.

[0059] 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 non-metallic inner 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 non-metallic inner 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 non-metallic inner frame 10 by a sealant can ensure that the light-transmitting panel will not be damaged due to excessive force during the connection process.

[0060] Exemplarily, a sealing groove is provided at the bottom of the non-metal inner frame 10, and a sealing member is installed in the sealing groove, and the sealing member is used to seal the connection between the bottom shell 50 and the non-metal inner frame 10. The sealing member can be set as a rubber ring to improve the sealing effect of the connection between the bottom shell 50 and the non-metal inner frame 10.

[0061] Specifically, the head-type automobile key further includes a main control board 60 installed in the installation cavity, the bottom shell 50 is a plastic bottom shell 50, and the communication element 30 is located on the side of the main control board 60 facing the display panel 40. The plastic bottom shell 50 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 30, thereby further ensuring the signal transmission effect of the communication element 30.

[0062] 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.

[0063] In the technical solution of the head-type automobile key of the utility model, the middle frame component of the shell is a composite middle frame including a non-metallic inner frame 10 and a metal outer frame. The metal outer frame 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 automobile key. The non-metallic inner frame 10 can reduce the signal interference effect on the communication element 30, and the completely disconnected communication port 23 formed by the metal outer frame can provide a signal transmission channel for the communication signal between the communication element 30 and an external element (such as the vehicle system of the car), so that the signal transmitted and / or received by the communication element 30 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 automobile key can correctly identify the vehicle signal to improve the control effect of the car.

[0064] The above description is only an optional embodiment of the present invention, and does not limit the patent scope of the present invention.
