[0035] like Figures 1 to 3As shown, this embodiment provides a vehicle key housing. At least a portion of the housing 1 is composed of a dielectric substrate 13, wherein the dielectric substrate 13 has an outer surface and an inner surface facing away from each other. At least a portion of the outer surface is attached with a radiating patch 14, and at least a portion of the inner surface is attached with a ground plane 15, with the ground plane 15 at least partially corresponding to the radiating patch 14. The inner surface of the dielectric substrate 13 is also provided with an output port 16. The positive terminal 161 of the output port 16 passes through the dielectric substrate 13 and is connected to the radiating patch 14, while the negative terminal 162 of the output port 16 is connected to the ground plane 15, suitable for outputting the radio frequency energy collected by the radiating patch 14. In this way, the housing of the vehicle key can be used as a radio frequency energy collection antenna, which not only makes reasonable use of the structure of the vehicle key and saves layout space, but also effectively collects radio frequency energy in the external space as a power source for the vehicle key, improving the charging convenience of the vehicle key.

[0036] Specifically, at least a portion of the outer casing 1 is formed by a dielectric substrate 13. This can be achieved by fabricating the outer casing 1 or a portion thereof using the dielectric substrate 13, or by creating a groove in the outer casing 1 and fixing the dielectric substrate 13, to which the radiation patch 14 and ground plane 15 are attached, to the groove by embedding or other methods. In this embodiment, as... Figures 1 to 4 As shown, all components of the outer shell 1 are made of a dielectric substrate 13. The material can be FR-4 (Flame Retardant-4, flame retardant rating 4) epoxy resin board, aluminum substrate, or ceramic substrate, etc. It not only has sufficient strength and durability to accommodate the electronic components of the vehicle key, but also avoids seams and improves waterproof, moisture-proof, and dustproof performance. The radiating patch 14 and the ground plane 15 are made of copper material with a thickness of 35 micrometers. The radiating patch 14 and the ground plane 15 are attached to the outer and inner surfaces of the dielectric substrate 13, respectively, by means of hot pressing or bonding. The size of the radiating patch 14 can be slightly larger than the size of the ground plane 15, and the two are positioned correspondingly on the inner and outer surfaces of the dielectric substrate 13. Due to their extremely small thickness, the radiating patch 14 and the ground plane 15 will not increase the weight of the outer shell 1 excessively, nor will they occupy too much layout space. The comfort of use is similar to that of ordinary smart vehicle keys.

[0037] Meanwhile, the inner surface of the dielectric substrate 13 is also provided with an output port 16. A via 131 can be formed on the dielectric substrate 13 corresponding to the location of the output port 16, allowing the positive terminal 161 of the output port 16 to pass through the via 131 and connect to the radiating patch 14, while its negative terminal 162 connects to the ground plane 15. In the area where the via 131 is provided, the ground plane 15 may coincide with the dielectric substrate 13 in the height direction. In this case, the via 131 can... Figure 3The diagram shows a through-hole configuration between the ground plane 15 and the dielectric substrate 13. The output port 16 can be a coaxial connector, with its positive terminal 161 passing through the via 131 and connecting to the radiating patch 14, and its negative terminal 162 connected to the ground plane 15. It is then connected via a coaxial cable to an RF rectifier inside the housing 1 to output the RF energy collected by the radiating patch 14. Alternatively, the via 131 can be located where the dielectric substrate 13 and the ground plane 15 do not overlap. In this case, the positive terminal 161 of the output port 16 can be directly connected to the radiating patch 14 via the via 131 using a wire or probe, while its negative terminal 162 can be directly connected to the ground plane 15.

[0038] It is understandable that when a portion of the outer casing 1 is composed of the dielectric substrate 13, the radiating patch 14 and the ground plane 15 are disposed in the area composed of the dielectric substrate 13. Other areas of the outer casing 1 not composed of the dielectric substrate 13 can be connected to the boundary of the area where the dielectric substrate 13 is located by a waterproof material, thereby improving its waterproof, moisture-proof, and dustproof performance. When all the structures of the outer casing 1 are composed of the dielectric substrate 13, the radiating patch 14 and the ground plane 15 can also be disposed in a portion of the outer casing 1, and an anti-corrosion coating can be applied to the areas of the dielectric substrate 13 where the radiating patch 14 is not attached. The arrangement can be selected according to the specific design shape of the outer casing 1, and there are no restrictions here.

[0039] In some embodiments, such as Figures 1 to 4 As shown, the housing 1 includes a top cover 11 and a bottom cover 12. The top cover 11 and the bottom cover 12 are detachably connected with their inner surfaces facing each other. The detachable connection method includes, but is not limited to, snap-fit ​​or bolt connection. After the top cover 11 and the bottom cover 12 are connected and closed, a receiving space for accommodating electronic components for accommodating the vehicle key is formed between the top cover 11 and the bottom cover 12. The top cover 11 or at least a portion thereof is composed of a dielectric substrate 13, and the bottom cover 12 or at least a portion thereof is also composed of a dielectric substrate 13. In this way, both the top cover 11 and the bottom cover 12 have the function of collecting radio frequency energy, that is, the top cover 11 and the bottom cover 12 can be used simultaneously as radio frequency energy collecting antennas, thereby collecting as much radio frequency energy as possible from the external space.

[0040] In some embodiments, such as Figure 1 and Figure 2As shown, the top cover 11 has a first mounting area 111 and a second mounting area 112 spaced apart. The first mounting area 111 is suitable for attaching the radiating patch 14 and the ground plane 15. The second mounting area 112 forms a mounting groove for mounting the button module 3. In this embodiment, the mounting groove is formed on the outer surface of the top cover 11 and has a through hole communicating with the inner surface, so that the button module 3 can be connected to the electronic components in the receiving space. By spaced apart the first mounting area 111 and the second mounting area 112, the top cover 11 can be divided into different functional areas to avoid mutual interference.

[0041] In some embodiments, such as Figure 1 and Figure 4 As shown, the bottom cover 12 has a third mounting area 121 and a fourth mounting area 122 spaced apart. The third mounting area 121 is suitable for attaching the radiating patch 14 and the ground plane 15; the fourth mounting area 122 forms a battery compartment for mounting the battery module 4. In this embodiment, the battery compartment is formed on the inner surface of the bottom cover 12 for the battery module 4 to be snapped and fixed. By spaced apart the third mounting area 121 and the fourth mounting area 122, the bottom cover 12 can be divided into different functional areas to avoid mutual interference.

[0042] It is understood that the first mounting area 111 is suitable for attaching the radiating patch 14 and the ground plane 15. This can be because the first mounting area 111 of the top cover 11 is composed of the dielectric substrate 13, or because all areas of the top cover 11 are composed of the dielectric substrate 13, but only the first mounting area 111 has the radiating patch 14 and the ground plane 15 attached. Similarly, the third mounting area 121 is suitable for attaching the radiating patch 14 and the ground plane 15. This can be because the third mounting area 121 of the bottom cover 12 is composed of the dielectric substrate 13, or because all areas of the bottom cover 12 are composed of the dielectric substrate 13, but only the third mounting area 121 has the radiating patch 14 and the ground plane 15 attached.

[0043] In some embodiments, such as Figure 5 As shown, the radiating patch 14 includes a plurality of micro-patterns 141 arranged in an array, and the plurality of micro-patterns 141 are connected to the output port 16 via conductive lines 142. By arranging the radiating patches 14 in an array, its ability to collect radio frequency energy can be improved.

[0044] Specifically, the conductive line 142 can be a copper wire integrated on the dielectric substrate 13, having one main path and multiple branches. The main path connects to the positive terminal 161 of the output port 16, and the branches connect to multiple micro-patterns 141 respectively. The micro-patterns 141 are rectangular and arranged in a 4×2 array, which not only provides uniform distribution and ease of fabrication but also effectively enhances the radio frequency energy collection capability. It is understood that the array form, size, structural shape, and number of the micro-patterns 141 can be arbitrarily combined according to the required operating frequency, as long as it can meet the radio frequency energy collection requirements of the required operating frequency. No restrictions are imposed here, nor will they be elaborated further.

[0045] In some embodiments, such as Figure 6 As shown, the radiating patch 14 is constructed as a trademark or logo. In this embodiment, the radiating patch 14 is constructed as an exemplary pattern of overlapping lightning bolts. In other embodiments, the shape of the radiating patch 14 can be constructed as a trademark or abbreviated letter, Chinese character, pattern, or other logo of the corresponding car company or car logo, which can beautify the appearance of the vehicle key and enhance the identification of the company or car logo to which the vehicle key belongs.

[0046] It is understandable that when the radiating patch 14 needs to meet a specific operating frequency, the radiating patch 14, which is designed as a trademark or logo, can vary in size and, for example... Figure 7 As shown, by cutting or adding several circular, rectangular, or other shaped structures, the radio frequency energy harvesting requirements for a specific operating frequency can be met.

[0047] In some embodiments, the top cover 11 and the bottom cover 12 are configured to collect radio frequency energy at a first frequency or a second frequency; wherein the first frequency is 2.4 GHz to 2.5 GHz, preferably 2.45 GHz, and the second frequency is 5.75 GHz to 5.85 GHz, preferably 5.8 GHz. Due to the widespread use of IoT devices and signal base stations, the radio frequency energy generated by these devices is mainly at 2.45 GHz and 5.8 GHz. Therefore, setting the operating frequencies of the top cover 11 and the bottom cover 12 to the first frequency or the second frequency can effectively improve the energy collection efficiency of the housing 1, thereby increasing the charging rate.

[0048] In some embodiments, the frequency of the radio frequency energy collected by the top cover 11 is a first frequency, and the frequency of the radio frequency energy collected by the bottom cover 12 is a second frequency; or the frequency of the radio frequency energy collected by the top cover 11 is a second frequency, and the frequency of the radio frequency energy collected by the bottom cover 12 is a first frequency. In this way, by designing the top cover 11 and the bottom cover 12 to operate at different frequencies, as much radio frequency energy in the external space as possible can be collected.

[0049] like Figure 1 and Figure 8As shown, in another embodiment, a vehicle key is also provided. The vehicle key includes the housing of the vehicle key described above, and further includes: a button module 3, a communication module 23, a rechargeable battery module 4, an energy conversion module 21, and an energy management module 22. The button module 3 is configured to receive control commands input by the user; the communication module 23 is configured to communicate with the vehicle; the rechargeable battery module 4 is connected to the button module 3 and the communication module 23 to supply power to the button module 3 and the communication module 23; the energy conversion module 21 is connected to the output port 16 of the housing 1 to receive radio frequency energy collected by the housing 1 and convert the radio frequency energy into DC energy; the energy management module 22 is connected to the energy conversion module 21 and the battery module 4 to receive DC energy and charge the battery module 4 after voltage regulation. With the above configuration, the vehicle key can collect radio frequency energy from the external space through the shell 1 composed of the radiation patch 14, the dielectric substrate 13 and the ground plane 15 and transmit it to the energy conversion module 21. The radio frequency energy is converted into DC energy by the energy conversion module 21 and then sent to the energy management module 22. Subsequently, the DC energy is boosted by the energy management module 22 and can be charged into the battery module 4 for storage, and can meet the power needs of the communication module 23 and the button module 3.

[0050] Specifically, such as Figure 1 and Figure 8 As shown, the communication module 23, energy conversion module 21, and energy management module 22 are integrated on the circuit board 2. The button module 3 is installed in the mounting slot of the top cover 11, and the rechargeable battery module 4 is installed in the battery compartment of the bottom cover 12. Then, the button module 3 and the rechargeable battery module 4 are connected to the energy management module 22 on the circuit board 2 via wires. Finally, the top cover 11 and the bottom cover 12 are closed, thus completing the assembly of the vehicle key. The button module 3 can be a microswitch, which can convert the user's pressing action signal into an electrical signal and transmit it to the communication module 23. The communication module 23 can communicate with the vehicle's in-vehicle receiver 5 using short-range communication methods such as Bluetooth, NFC, and WiFi, thereby enabling remote locking and unlocking of the vehicle's doors, trunk door, etc. The energy conversion module 21 can be an RF rectifier, which can convert RF energy into DC energy and transmit it to the energy management module 22. The energy management module 22 can employ a voltage regulator circuit from the prior art. On one hand, it can boost the DC energy delivered by the energy conversion module 21 and then deliver it to the battery module 4 for storage. On the other hand, it can extract power from the battery module 4 to power the communication module 23 and the button module 3. The specific connecting components of the voltage regulator circuit are from the prior art and will not be described in detail here.

[0051] The vehicle key based on the above implementation scheme can generate electrical energy to power itself through radio frequency energy harvesting, eliminating the need to replace batteries and improving user convenience.

[0052] It is understandable that when the outer casing 1 includes a top cover 11 and a bottom cover 12, it has two output ports 16, located on the top cover 11 and the bottom cover 12 respectively. When the operating frequencies of the top cover 11 and the bottom cover 12 are the same, the energy conversion module 21 can use only one RF rectifier. The output ports 16 of the top cover 11 and the bottom cover 12 can be connected together via a connecting harness and then connected to the input port of the RF rectifier. When the operating frequencies of the top cover 11 and the bottom cover 12 are different, the energy conversion module 21 can use two RF rectifiers with different operating frequencies, or a dual-frequency rectifier. The output ports 16 of the top cover 11 and the bottom cover 12 can be connected to the two input ports of the two RF rectifiers or the dual-frequency rectifier with different operating frequencies via a connecting harness.
