[0028] With the continuous development of technology, smartwatches have become an indispensable part of people's lives. One particularly convenient function is operating a car key via a smartwatch. This is achieved by using a communication element installed within the watch to receive and transmit frequency signals from the vehicle's infotainment system, allowing users to operate the car key function through the watch. However, current smartwatches typically place the communication element inside the watch itself. This element is susceptible to interference from the watch's metal casing and internal electronic components. This high level of interference reduces the signal reception and transmission performance of the communication element, making it difficult for the watch to accurately identify vehicle signals and potentially causing signal reception failure, thus preventing the watch from fulfilling its normal car key function requirements.

[0029] This utility model proposes a meter-type car key, aiming to solve the technical problem of how to improve the signal transmission effect between the meter-type car key and the car.

[0030] In the embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the meter-type car key includes: a housing with a mounting cavity 11, the housing including a display panel 12, a middle frame 13, and a bottom shell 14, the middle frame 13 being annularly arranged, at least part of the middle frame 13 being made of non-metallic material, the display panel 12 covering the top side of the middle frame 13, and the bottom shell 14 covering the bottom side of the middle frame 13; a main control board 24, the main control board 24 being mounted in the mounting cavity 11; and a communication module 25, the communication module 25 being mounted in the mounting cavity 11 and electrically connected to the main control board 24, the communication module 25 being used to communicate with the vehicle's infotainment system so that the meter-type car key can control the vehicle through the communication module 25.

[0031] In this embodiment, the watch-style car key can be understood as integrating the contactless car control function of a car key into a smartwatch or quartz watch, allowing users to control their car without contact by wearing the smartwatch or quartz watch on their wrist. In addition to contactless car control, the watch-style car key can also display the time.

[0032] Taking a quartz watch as an example, the watch head type car key may also include a dial 21, which is installed in the mounting cavity 11 and exposed through the display panel 12; a quartz movement 22, which is installed on the side of the dial 21 away from the display panel 12, and is electrically connected to the main control board 24, with the drive shaft of the quartz movement 22 passing through the dial 21; and a hand 23, which is installed between the dial 21 and the display panel 12, and is connected to the drive shaft of the quartz movement 22.

[0033] The housing provides mounting cavities 11 for the functional components of the watch-type car key, serving a protective function. The watch-type car key may also include a battery electrically connected to the main control board 24, which supplies power to the main control board 24, which then distributes the power to the quartz movement 22 and the communication module 25. The quartz movement 22 includes a quartz oscillator, a stepper motor, and a gear train. Utilizing the piezoelectric effect of the quartz crystal, the movement 22 uses power supplied by the battery to the quartz crystal, causing it to vibrate at a fixed frequency. This frequency is typically 32,768 times per second. The weak current generated by the vibration is amplified by the circuitry, driving the watch hands 23. The display panel 12 is transparent, allowing the side of the dial 21 facing the display panel 12 to be visible. The dial 21 has time markings, and the user can obtain the current time by indicating the time with the hands 23.

[0034] The communication module 25 can be paired and communicate with the vehicle's infotainment system, allowing users to wirelessly communicate with the system via the meter-type car key, thereby controlling the car's locking and unlocking functions. The communication module 25 can communicate with mobile terminals and the infotainment system in various ways, such as via Bluetooth, 3G, 4G, or 5G networks; no specific restrictions are imposed here.

[0035] For example, the communication module 25 can be part of a smart key system. A smart key system (PASSIVEKEYLESS ENTER), or PKE for short, employs RFID wireless radio frequency technology and a vehicle identification coding system. It utilizes a miniaturized, low-power radio frequency antenna development scheme, integrating a remote control system and a keyless system. It retains traditional vehicle circuit protection, achieving dual radio frequency systems and dual anti-theft protection. In the PKE system, the car acts as a base station, and the parking number plate acts as a transponder to achieve two-way communication. The communication module 25 includes components such as a receiving antenna, a microcontroller, a high-frequency transmitting circuit, a low-frequency receiving circuit, and control switches.

[0036] Of course, the communication module 25 can also be a component in ultra-wideband wireless carrier communication technology. Ultra-wideband (UWB) is a new wireless technology that differs greatly from traditional communication technologies. It transmits and receives data from vehicles using extremely narrow pulses at or below the nanosecond level, with a bandwidth in the range of 3.1 to 10.6 GHz, making it less susceptible to interference from other signals. Through UWB interaction between the parking number plate and the vehicle, the positioning algorithm can identify the distance to the vehicle at the centimeter level, easily achieving rapid response and allowing users to control the vehicle automatically and seamlessly using the parking number plate.

[0037] The non-metallic part of the middle frame 13 provides a signal transmission area for communication signals between the communication module 25 and the vehicle's infotainment system. This allows the signals transmitted and / or received by the communication module 25 to interact with the infotainment system through the signal transmission area, thereby significantly improving the signal transmission strength and ensuring that the meter-type car key can correctly identify vehicle signals, thus improving the control effect of the car.

[0038] Specifically, such as Figure 2 As shown, the middle frame 13 includes a metal main frame 131 and a non-metallic sub-frame 132, which are connected along the height direction of the middle frame 13. Both the metal main frame 131 and the non-metallic sub-frame 132 are annular. The non-metallic sub-frame 132 can be a rubber frame or a plastic frame, without limitation. The height of the metal main frame 131 is greater than the height of the non-metallic sub-frame 132, so that the main part of the middle frame 13 can present a metallic texture. The non-metallic sub-frame 132 provides an annular signal transmission area for communication signals between the communication module 25 and the vehicle's infotainment system, allowing signals transmitted / received by the communication module 25 to enter and exit the mounting cavity 11 from all sides of the middle frame 13, further improving the signal transmission effect of the communication module 25.

[0039] In practical applications, such as Figure 2 As shown, the display panel 12 is covered on the top side of the metal main frame 131, the non-metallic sub-frame 132 is connected to the bottom side of the metal main frame 131, and the bottom shell 14 is covered on the bottom side of the non-metallic sub-frame 132.

[0040] The side of the middle frame 13 closest to the display panel 12 is usually the side that is easier for users to see and touch. Therefore, by using the metal main frame 131 as the part of the middle frame 13 closest to the display panel 12, users can mainly see and touch the metal main frame 131 when viewing and touching the middle frame 13. The metal main frame 131 can make the appearance of the middle frame 13 more metallic and the feel smoother, thereby effectively improving the visual and tactile experience of the meter-type car key.

[0041] For example, such as Figure 2 As shown, the quartz movement 22 is mounted on the surface of the main control board 24 facing the display panel 12, and the communication module 25 is mounted on the surface of the main control board 24 facing the bottom shell 14. This allows the communication module 25 to be at least partially located within the enclosure of the non-metallic sub-frame 132, making it easier for the communication signal of the communication module 25 to enter and exit the shell through the non-metallic sub-frame 132, thereby further improving the signal transmission effect of the communication module 25.

[0042] Specifically, such as Figure 2As shown, the outer diameter of the non-metallic sub-frame 132 decreases from the side closer to the metal main frame 131 towards the side closer to the bottom shell 14. When the dial-type car key is worn on the wrist, the decreasing outer diameter can conceal the outer surface of the non-metallic sub-frame 132, making it less likely to be seen or touched. This reduces the visual and tactile differences caused by the different materials of the metal main frame 131 and the non-metallic sub-frame 132, thereby improving the overall appearance and tactile consistency of the dial-type car key.

[0043] In practical applications, such as Figure 2 As shown, the meter-type car key also includes a sealing ring 30, which is disposed at the connection between the metal main frame 131 and the non-metallic sub-frame 132. A sealing groove can be formed in the bottom wall of the metal main frame 131, and the non-metallic sub-frame 132 presses the sealing ring 30 into the sealing groove. The sealing ring 30 can seal the gap between the metal main frame 131 and the non-metallic sub-frame 132, preventing moisture or dust from entering the mounting cavity 11, thereby improving the internal structural stability of the meter-type car key.

[0044] For example, such as Figure 3 As shown, the outer wall of the metal frame 131 is provided with at least two mounting protrusions 133, which are used to connect to the same end of the watch strap. The mounting protrusions 133 can be integrally formed with the metal frame 131. Setting the mounting protrusions 133 on the metal frame 131 can improve the structural strength of the mounting protrusions 133 and the connection strength with the middle frame 13, and ensure the structural stability of the mounting protrusions 133. The metal frame 131 can be provided with four mounting protrusions 133, with two mounting protrusions 133 forming a group. One end of the watch strap is connected to one group of mounting protrusions 133, and the other end is connected to another group of mounting protrusions 133.

[0045] Specifically, the watch-type car key also includes a watch strap, the end of which is detachably connected to the mounting protrusion 133. The watch strap can be worn around the user's wrist to wear the watch-type car key. The watch strap can be a single piece or a two-piece design, without limitation. The tightness of the watch strap is adjustable to accommodate users with different wrist sizes. The watch strap can be made of materials such as leather, TPU, or silicone, or it can be made of metal. The watch strap is rotatably connected to the mounting protrusion 133. Detachably connecting the watch strap to the mounting protrusion 133 allows the user to remove the watch strap and carry the watch-type car key directly in a bag or pocket when they do not wish to wear it, adapting to different usage scenarios.

[0046] In practical applications, such as Figure 3As shown, a button recess 134 is provided on the outer wall of the metal main frame 131, and a button hole 135 is provided at the bottom of the button recess 134, connecting the mounting cavity 11 and the button recess 134. The button recess 134 is used for button installation. A trigger switch is provided in the mounting cavity 11 adjacent to the button hole 135. The trigger switch and the button abut against each other through the button hole 135, so that the user can control the trigger switch by pressing the button to control other functions of the meter-type car key. Since the button hole 135 connects the mounting cavity 11 to the outside, when the button is a rubber button or a plastic button, the communication signal of the communication module 25 can also enter and exit the mounting cavity 11 through the button hole 135. That is to say, the button hole 135 can also provide the communication module 25 with a signal transmission channel that is not affected by the metal main frame 131, thereby further improving the signal transmission effect of the communication module 25.

[0047] This utility model also proposes an automotive component, which includes a car and a meter-type car key. The specific structure of the meter-type car key is as described in the above embodiments. Since this automotive component adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be repeated here. The meter-type car key is communicatively connected to the car.

[0048] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
