Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a meter-type car key and automotive components. Background Technology

[0002] 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.

[0030] 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.

[0031] 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.

[0032] In the embodiments of this utility model, such as Figures 1 to 3 As shown, Figure 1 This is a schematic diagram of the structure of an embodiment of the meter-type car key of this utility model; Figure 2 This is an exploded view of the structure of an embodiment of the meter-type car key of this utility model; Figure 3 This is a schematic diagram of a structure of an embodiment of the metal frame 10 in this utility model.

[0033] The watch head type car key includes: a housing having a mounting cavity; the housing including a metal frame 10 arranged in an overall ring shape; the outer side wall of the metal frame 10 having a first connection position 11 and a second connection position 12, the first connection position 11 and the second connection position 12 being used for connecting the two ends of the watch strap respectively; the metal frame 10 including a first metal sidewall and a second metal sidewall located between the first connection position 11 and the second connection position 12, the first metal sidewall and the second metal sidewall being located on opposite sides of the metal frame 10 respectively; at least one of the first metal sidewall and the second metal sidewall having a communication port, the communication port communicating between the mounting cavity and the outside of the housing; and a communication element 20 installed in the mounting cavity, the communication element 20 being used to communicate with elements outside the mounting cavity.

[0034] In this embodiment, the watch-style car key can be understood as integrating the car key's vehicle control function into a smartwatch, allowing users to control their car by wearing the smartwatch on their wrist. The watch-style car key may only have the function of controlling the car, or it may also have other functions such as displaying the time and providing notifications.

[0035] The outer casing provides mounting cavities for the functional components of the meter-type car key, thus providing protection. The metal frame 10 is part of the outer casing. The metal frame 10 is made of metal, which gives the outer casing a more metallic appearance and improves the overall structural strength of the outer casing, thereby enhancing the impact resistance of the meter-type car key.

[0036] The housing also includes a display panel 40 and a bottom shell 50, which are respectively disposed at the top and bottom of the metal frame 10. The display panel 40, the bottom shell 50, and the metal frame 10 together form the mounting cavity. The display panel 40 has a touch interface, which can display functional information such as time and current vehicle status, and can also allow users to control the car key function by touch.

[0037] The communication element 20 is used to achieve wireless communication with the vehicle so that the user can control the vehicle through the meter-type car key. There are many ways for the communication element 20 to communicate with the vehicle system, such as wireless communication through Bluetooth, 3G network, 4G network or 5G network, etc., which are not limited here.

[0038] For example, communication element 20 can be part of a smart key system (PASSIVE KEYLESS ENTER, or PKE for short). This system uses RFID wireless radio frequency technology and a vehicle identification coding system, employing a miniaturized, low-power radio frequency antenna development scheme. It integrates a remote control system and a keyless system, retaining 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 meter-type car key acts as a transponder to achieve two-way communication. Communication element 20 includes components such as a receiving antenna, a microcontroller, a high-frequency transmitting circuit, a low-frequency receiving circuit, and control switches.

[0039] Of course, communication element 20 can also be a component in ultra-wideband wireless carrier communication technology. Ultra-wideband (UWB) employs a new ultra-wideband wireless technology that differs significantly from traditional communication technologies. It transmits and receives data from vehicles using extremely narrow pulses at or below the nanosecond level, boasting a bandwidth in the range of 3.1–10.6 GHz, making it less susceptible to interference from other signals. Through the UWB interaction between the meter-type car key and the vehicle's UWB, the positioning algorithm can identify the distance to the vehicle at the centimeter level, easily achieving rapid response and allowing users to control their vehicles automatically and seamlessly while wearing the meter-type car key.

[0040] The communication port allows communication signals between the communication element 20 and the vehicle to bypass the metal frame 10 when entering and exiting the housing, thus preventing the metal frame 10 from interfering with the signal transmission of the communication element 20. The number of communication ports can be one, two, or more, without limitation. The shape of the communication port can be rectangular, triangular, circular, elliptical, or other regular shapes, or irregular shapes, without limitation. The width of the communication port is less than the height of the metal frame 10, and the length of the communication port is less than the perimeter of the metal frame 10; the specific dimensions of the communication port are not limited. The communication port provides a signal transmission channel for communication signals between the communication element 20 and external components (such as the vehicle's infotainment system), allowing signals transmitted and / or received by the communication element 20 to interact with external vehicles or accessories through this channel. This significantly improves the signal transmission strength, ensuring that the meter-type car key can correctly identify vehicle signals, thereby improving the control effect of the vehicle.

[0041] The first connecting position 11 and the second connecting position 12 are respectively located on opposite sides of the metal frame 10, for connecting the two ends of the watch strap. The two ends of the watch strap are typically connected to the 6 o'clock and 12 o'clock positions of the metal frame 10, respectively. Therefore, the first connecting position 11 and the second connecting position 12 can be located at the 6 o'clock and 12 o'clock positions of the metal frame 10. Since the communication port is located between the first connecting position 11 and the second connecting position 12, the communication port can be located at at least one of the 3 o'clock and 9 o'clock positions of the metal frame 10.

[0042] The number of communication ports can be one or two.

[0043] Specifically, such as Figure 3 As shown, there are two communication ports, including a first communication port 13 and a second communication port 14. The first communication port 13 is located on the first metal sidewall, and the second communication port 14 is located on the second metal sidewall. Setting the number of communication ports to two increases the number of positions on the metal frame 10 where communication signals from the communication element 20 can enter and exit, thereby further improving the communication effect between the communication element 20 and the vehicle.

[0044] In practical applications, such as Figure 3 As shown, the meter-type car key also includes a first non-metallic filler 31 and a second non-metallic filler 32. The first non-metallic filler 31 fills the first communication port 13, and the second non-metallic filler 32 fills the second communication port 14.

[0045] The first non-metallic filler 31 can seal the first communication port 13, and the second non-metallic filler 32 can seal the second communication port 14, thereby preventing external dust or moisture from entering the mounting cavity through the first communication port 13 and the second communication port 14, effectively protecting the communication element 20. The first non-metallic filler 31 and the second non-metallic filler 32 can be made of rubber, plastic, ceramic, etc., without limitation. It is understood that the first non-metallic filler 31 and the second non-metallic filler 32 will not have any shielding or interference effect on the communication signal of the communication element 20, thus ensuring the normal operation of the communication element 20.

[0046] For example, such as Figure 3As shown, the first non-metallic filler 31 has a button hole 311, which communicates with the mounting cavity. The button hole 311 is used for button installation. A trigger switch is provided in the mounting cavity adjacent to the button hole 311. The trigger switch and the button abut against each other through the button hole 311, so that the user can control the trigger switch by pressing the button to control other functions of the meter-type car key. Installing the button on the first non-metallic filler 31 instead of on the first or second metal sidewall allows direct use of the first communication port 13, improving the effective utilization rate of the first communication port 13; it also avoids having too many holes on the outer sidewall of the metal frame 10, thus ensuring the structural strength of the metal frame 10.

[0047] Since a button hole 311 needs to be formed on the first non-metallic filler 31, it requires more area for the opening compared to the second non-metallic filler 32. Specifically, the width of the first communication port 13 is greater than the width of the second communication port 14, so that the width of the first non-metallic filler 31 can be greater than the width of the second non-metallic filler 32, ensuring sufficient area for the opening on the first non-metallic filler 31. Furthermore, because the widths of the first communication port 13 and the second communication port 14 are different, it also serves as a foolproof method when assembling electronic components, allowing assemblers to purposefully install the trigger switch near the first communication port 13, thereby improving assembly efficiency.

[0048] For example, the communication port extends circumferentially along the metal frame 10, with its two ends close to the first connection position 11 and the second connection position 12, respectively. This effectively utilizes the length dimensions of the first and second metal sidewalls to maximize the opening area of ​​the communication port, further improving the transmission effect of communication signals to the communication element 20.

[0049] Specifically, such as Figure 5 As shown, Figure 5 This is a projected schematic diagram of another embodiment of the metal frame 10 in this utility model. The width d of the communication port is greater than 1 / 3 of the height h of the metal frame 10. In this way, the communication port has a sufficient dimensional proportion in the height direction of the metal frame 10 to ensure the opening area of ​​the communication port on the metal frame 10 and improve the transmission effect of the communication signal of the communication element 20.

[0050] For example, such as Figure 4 As shown, Figure 4This is a projected schematic diagram of an embodiment of the metal frame 10 of this utility model. The outer wall of the metal frame 10 has two first mounting protrusions 15 at the first connection position 11, the two first mounting protrusions 15 being used for connecting the same end of the watch strap; and / or, the outer wall of the metal frame 10 has two second mounting protrusions 16 at the second connection position 12, the two second mounting protrusions 16 being used for connecting the same end of the watch strap.

[0051] Taking the first connection position 11 as an example, the two first mounting protrusions 15 have first shaft holes on their facing sides, and the end of the watch strap is provided with a connecting shaft. The two ends of the connecting shaft are respectively engaged with the two shaft holes to realize the rotatable connection between the watch strap and the two first mounting protrusions 15.

[0052] Specifically, the watch head type car key also includes a watch strap, the two ends of which are detachably connected to the first connecting position 11 and the second connecting position 12, respectively. The watch strap can be worn around the user's wrist to achieve the wearing of the watch head type car key. The watch strap can be a single piece or a two-piece piece, 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. In conjunction with the above embodiment of the first mounting protrusion 15 and the second mounting protrusion 16, the watch strap can be rotatably connected to the first mounting protrusion 15 and the second mounting protrusion 16. Detachably connecting the watch strap to the metal frame 10 allows the user to remove the watch strap and carry the watch head type car key directly in a bag or pocket when they do not want to wear it, to meet the user's different usage needs.

[0053] 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.

[0054] In the technical solution of this meter-type car key, the metal frame 10 gives the outer shell a more metallic texture and improves the overall structural strength of the shell, thereby enhancing the impact resistance of the meter-type car key. The communication port provides a signal transmission channel for communication signals between the communication element 20 and external components (such as the car's infotainment system). This allows signals transmitted and / or received by the communication element 20 to interact with external vehicles or accessories through the signal transmission channel, significantly improving the signal transmission strength and ensuring that the meter-type car key can correctly identify vehicle signals, thus improving the control effect on the car.

[0055] 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.
