[0029] With the continuous development of technology, smartwatches have become an indispensable part of people's lives. One particularly convenient function is operating car keys through a smartwatch. This is achieved by using communication components installed within the watch to receive and transmit frequency signals from the car's infotainment system, allowing users to control the car key function directly from the watch. However, existing smartwatches typically lack static electricity elimination capabilities, failing to remove static electricity from the wearer in environments prone to static buildup, thus affecting the smartwatch's usability.

[0030] This application proposes a meter-type car key, aiming to solve the technical problem of how to improve the usability of meter-type car keys.

[0031] In this embodiment of the application, as shown in Figures 1 and 2, the meter-type car key includes: a housing 10, the housing 10 having a mounting cavity 11, the housing 10 including a display panel 12, a middle frame 13, and a bottom shell 14, the middle frame 13 being annularly arranged, the display panel 12 covering the top side of the middle frame 13, the bottom shell 14 covering the bottom side of the middle frame 13, and the bottom shell 14 having a first through hole 15 and a second through hole 16; and a communication module 20, the communication module 20 being installed in the mounting cavity 11, the communication module 20 being used to communicate with the car's infotainment system. A communication connection is provided so that the meter-type car key can control the car through the communication module 20; a first electrode 31 and a second electrode 32 are respectively installed in the first through hole 15 and the second through hole 16, and the exposed ends of the first electrode 31 and the second electrode 32 protrude from the outer surface of the bottom shell 14 or are flush with the outer surface of the bottom shell 14; the first electrode 31 and the second electrode 32 are electrically connected in the mounting cavity 11 so that the first electrode 31 and the second electrode 32 form an electrostatic absorption circuit after contacting the human body.

[0032] 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.

[0033] The housing 10 provides a mounting cavity 11 for the functional components of the meter-type car key, serving a protective function. The communication module 20 can pair and communicate with the vehicle's infotainment system, allowing the user to wirelessly communicate with the system via the meter-type car key, thereby controlling the car's locking and unlocking functions. The communication module 20 can communicate with mobile terminals and the vehicle's infotainment system in various ways, such as via Bluetooth, 3G, 4G, or 5G networks; no specific restrictions are imposed here.

[0034] For example, the communication module 20 can be part of a smart key system. A smart key system (PASSIVE KEYLESS 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 20 includes components such as a receiving antenna, a microcontroller, a high-frequency transmitting circuit, a low-frequency receiving circuit, and control switches.

[0035] Of course, the communication module 20 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.

[0036] The first electrode 31 and the second electrode 32 are metal electrodes. One end of the first electrode 31 is exposed through the first through hole 15, and one end of the second electrode 32 is exposed through the second through hole 16. The exposed ends of the first electrode 31 and the second electrode 32 protrude from or are flush with the outer surface of the bottom shell 14. Thus, when the user wears the dial-type car key on their wrist, the first electrode 31 and the second electrode 32 can contact the wearer's skin, so that the first electrode 31, the second electrode 32 and the wearer's skin together form an electrostatic absorption circuit. The electrostatic absorption circuit can conduct the static charge attached to the wearer's body into the dial-type car key to eliminate static electricity, thereby improving the performance of the dial-type car key.

[0037] In one embodiment, as shown in FIG2, the meter-type car key further includes a main control board 41 and a battery 42. The communication module 20 is electrically connected to the main control board 41. The main control board 41 is provided with a charging circuit, which is electrically connected to the battery 42. The first electrode 31 and the second electrode 32 are respectively electrically connected to the charging circuit. The exposed ends of the first electrode 31 and the second electrode 32 are used to contact the external charging electrode.

[0038] Battery 42 provides power to main control board 41, which then distributes the power to communication module 20. Battery 42 can be charged using a charger compatible with the meter-type car key. The charger has two charging electrodes. When the meter-type car key is being charged, the first electrode 31 and the second electrode 32 respectively come into contact with the two charging electrodes to form a charging circuit, allowing current to flow through the charging circuit to battery 42. In this way, the first electrode 31 and the second electrode 32 can both eliminate static electricity from the wearer's body and serve as the charging interface for the meter-type car key, thereby improving the utilization rate of the first electrode 31 and the second electrode 32 and simplifying the internal structure of the meter-type car key.

[0039] In another embodiment, the meter-type car key further includes a main control board 41, a battery 42, and an electromagnetic receiving unit. The communication module 20 is electrically connected to the main control board 41. The main control board 41 is provided with a charging circuit. The battery 42 and the electromagnetic receiving unit are respectively electrically connected to the charging circuit. The electromagnetic receiving unit is used to receive electromagnetic induction signals emitted by an external electromagnetic transmitting unit to wirelessly charge the battery 42.

[0040] Battery 42 can be charged via a wireless charger compatible with the meter-type car key. The wireless charger is equipped with an electromagnetic transmitting unit, which can be an electromagnetic transmitting coil, and can emit electromagnetic induction signals. When charging the meter-type car key, the car key is placed on the wireless charger. The electromagnetic receiving unit can receive the electromagnetic induction signals emitted by the electromagnetic transmitting unit, and then convert the electromagnetic induction signals into electrical energy. The electrical energy can flow to battery 42 through the charging circuit to achieve wireless charging of battery 42.

[0041] For example, as shown in FIG3, the outer surface of the bottom shell 14 is provided with a first recessed groove 151, the first through hole 15 is provided at the bottom of the first recessed groove 151, the peripheral wall of the exposed end of the first electrode 31 is provided with a first limiting boss 311, the first limiting boss 311 is installed in the first recessed groove 151 to restrict the movement of the first electrode 31 into the mounting cavity 11; and / or, the outer surface of the bottom shell 14 is provided with a second recessed groove 161, the second through hole 16 is provided at the bottom of the second recessed groove 161, the peripheral wall of the exposed end of the second electrode 32 is provided with a second limiting boss 321, the second limiting boss 321 is installed in the second recessed groove 161 to restrict the movement of the second electrode 32 into the mounting cavity 11.

[0042] The first limiting protrusion 311 abuts against the bottom of the first recess 151, which can prevent the first electrode 31 from being squeezed into the mounting cavity 11 and displaced, thereby ensuring that the exposed end of the first electrode 31 can remain protruding from the outer surface of the bottom shell 14 or flush with the outer surface of the bottom shell 14, so as to ensure that the first electrode 31 can maintain effective contact with the wearer's skin, so as to achieve the effect of eliminating static electricity on the wearer's body surface.

[0043] Similarly, the second limiting protrusion 321 abuts against the bottom of the second recess 161, which can prevent the second electrode 32 from being squeezed into the mounting cavity 11 and displaced, thereby ensuring that the exposed end of the second electrode 32 can remain protruding from or flush with the outer surface of the bottom shell 14, so as to ensure that the second electrode 32 can maintain effective contact with the wearer's skin, thereby achieving the effect of eliminating static electricity on the wearer's body surface.

[0044] Specifically, as shown in Figure 2, the first limiting protrusion 311 extends circumferentially along the first electrode 31, thereby increasing the mating area between the first limiting protrusion 311 and the first groove 151, thus improving the limiting stability of the first electrode 31.

[0045] And / or, the second limiting boss 321 extends circumferentially along the second electrode 32, thereby increasing the mating area between the second limiting boss 321 and the second groove 161, so as to improve the limiting stability of the second electrode 32.

[0046] For example, as shown in FIG2, a support boss 141 is provided in the middle region of the bottom wall of the bottom shell 14, and the first through hole 15 and the second through hole 16 are formed in the support boss 141. The support boss 141 can ensure that the area of ​​the bottom shell 14 where the first electrode 31 and the second electrode 32 are located can effectively contact the wearer's skin, so as to ensure that the first electrode 31 and the second electrode 32 can effectively contact the wearer's skin.

[0047] Specifically, the bottom surface of the support boss 141 is convex, and the exposed ends of the first electrode 31 and the second electrode 32 protrude from or are flush with the bottom surface of the support boss 141. This further ensures that the first electrode 31 and the second electrode 32 can effectively contact the wearer's skin.

[0048] For example, as shown in FIG1, at least two mounting protrusions 50 are provided on the outer side wall of the middle frame 13, and the mounting protrusions 50 are used to connect to the same end of the watch strap. The mounting protrusions 50 can be integrally formed with the middle frame 13, and four mounting protrusions 50 can be provided on the middle frame 13. Two mounting protrusions 50 form a group, and one end of the watch strap is connected to one group of mounting protrusions 50, and the other end is connected to another group of mounting protrusions 50.

[0049] Specifically, the watch-type car key also includes a watch strap, the end of which is detachably connected to the mounting protrusion 50. 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 50. Detachably connecting the watch strap to the mounting protrusion 50 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.
