Detailed Implementation

[0018] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0019] The following is for reference. Figure 1 A vehicle remote control key 100 according to an embodiment of the present invention is described.

[0020] like Figure 1 As shown, the vehicle remote control key 100 according to the present invention includes: a housing 1, the housing 1 defining a receiving space 11; a circuit board 2, a battery 3, and a solar module 4, the circuit board 2, the battery 3, and the solar module 4 are all housed in the receiving space 11, the battery 3 is connected to the circuit board 2 and the solar module 4, the battery 3 is configured to supply power to the circuit board 2, and the solar module 4 is configured to convert solar energy into electrical energy and supply power to the battery 3.

[0021] The vehicle remote key 100 includes a housing 1, a circuit board 2, a battery 3, and a solar module 4. The housing 1 defines a receiving space 11, within which the circuit board 2, battery 3, and solar module 4 are all housed. The battery 3 is connected to both the circuit board 2 and the solar module 4; in some embodiments of this application, the battery 3 is connected to both the circuit board 2 and the solar module 4 via wires. The battery 3 is configured to supply power to the circuit board 2, enabling the circuit board 2 to control the vehicle remote key 100 to function normally.

[0022] The solar module 4 is configured to convert solar energy into electrical energy and supply power to the battery 3. Specifically, in bright areas, the solar module 4 converts solar energy into electrical energy and supplies power to the battery 3, and can also replenish the battery 3 in real time; in dark areas, the vehicle remote key 100 is powered by the power stored in the battery 3, enabling the vehicle remote key 100 to have a long battery life without disassembling the housing 1. It can also seal the housing 1, thereby effectively improving the waterproof and dustproof performance of the vehicle remote key 100 and effectively extending the service life of the vehicle remote key 100.

[0023] Therefore, by setting up the solar module 4, solar energy is converted into electrical energy in bright areas and supplied to the battery 3, while the battery 3 supplies power in dark areas, thus extending the battery life of the vehicle remote key 100. This reduces the risk of the vehicle remote key 100 failing due to a lack of power. Furthermore, the housing 1 does not need to be disassembled, which facilitates the sealing of the housing 1, thereby effectively improving the waterproof and dustproof performance of the vehicle remote key 100 and extending its service life.

[0024] In some examples of the present invention, such as Figure 1 As shown, the vehicle remote key 100 may further include: a Bluetooth communication module 5, which is housed in the housing space 11 and connected to the circuit board 2. The Bluetooth communication module 5 is configured to connect to a mobile terminal and / or an in-vehicle host to send the location information of the vehicle remote key 100.

[0025] The Bluetooth communication module 5, housed within the housing space 11, enables business communication and is connected to the circuit board 2. The battery 3 supplies power to the circuit board 2 to ensure the Bluetooth communication module 5 operates normally. In some embodiments of this application, the Bluetooth communication module 5 is configured to connect to a mobile terminal to transmit the location information of the vehicle remote key 100. In some embodiments of this application, the Bluetooth communication module 5 is configured to connect to an in-vehicle host to transmit the location information of the vehicle remote key 100. In some embodiments of this application, the Bluetooth communication module 5 is configured to connect to both a mobile terminal and an in-vehicle host to transmit the location information of the vehicle remote key 100. This configuration allows for real-time location tracking of the vehicle remote key 100, reducing the risk of loss and simplifying the search process.

[0026] In some examples of the present invention, the Bluetooth communication module 5 is configured as a channel detection and positioning Bluetooth module.

[0027] Currently, the mainstream Bluetooth positioning principles are mainly based on RSSI (Signal Strength Indicator) and angle information. However, the positioning accuracy of these two methods is limited. Bluetooth signals are easily interfered with in indoor environments, resulting in relatively low positioning accuracy. Furthermore, they are susceptible to signal interference; in densely populated environments, Bluetooth signals are easily interfered with, leading to increased positioning errors. In addition, device compatibility is poor; Bluetooth positioning systems require compatible devices. If a device does not support Bluetooth technology, positioning cannot be performed.

[0028] Channel sounding localization (SLT) is a technology that estimates and corrects distance by measuring the round-trip time and phase of signals at the output and receiver ends, offering higher accuracy and more secure protection mechanisms. The round-trip time refers to the duration required for a signal to travel from the transmitter to the receiver and back. Phase ranging is a method of determining distance using the phase changes of an RF signal. At frequency f, the distance is calculated by measuring the phase shift of the signal as it propagates over distance D. When using two or more signals of different frequencies, the phase difference between the signals can be measured to accurately estimate the distance; the specific calculation formula is as follows: Phase ranging (PBR) calculates distance (D) by measuring the phase delay (φ) of a modulated light or radio wave signal traveling one round trip over the target distance. The relationship between the angular frequency (ω) of the modulated signal and the phase delay (φ) can be expressed as a time (t) formula: t = φ / ω. Therefore, the distance D can be expressed as: D = 1 / 2ct = 1 / 2c·φ / ω, where c is the speed of light.

[0029] When using channel sensing to estimate distance, the two devices are a transmitter and a receiver, which exchange information through an RF physical channel. First, the transmitter transmits a signal and the receiver completes simple time synchronization. Then, the receiver reflects the signal without modifying the phase. During multiple transmissions at frequency fi, the phase change between the transmitted and received signals is measured and estimated using an algorithm. This alternating transmission and reception process achieves accurate distance measurement, thereby enabling precise positioning of the vehicle remote key 100.

[0030] Furthermore, as shown in Table 1, this application constructs the Bluetooth communication module 5 as a channel sensing and positioning Bluetooth module. Compared with Bluetooth RSSI and Bluetooth AoA / AoD positioning, the channel sensing and positioning Bluetooth module has the following advantages: Table 1

[0031] In some examples of the present invention, such as Figure 1 As shown, the vehicle remote key 100 may also include: a function module 6, which is housed in the housing space 11 and connected to the circuit board 2, and the function module 6 is configured to issue a prompt message.

[0032] The function module 6 is housed within the housing space 11 and is connected to the circuit board 2. The battery 3 supplies power to the circuit board 2 to enable the function module 6 to function normally. The function module 6 is configured to emit a prompt tone. In some embodiments of this application, the function module 6 is constructed as a speaker, for example, emitting a "I'm here" sound or a beeping sound. In some embodiments of this application, the function module 6 is constructed as an indicator light, for example, emitting a solid red light or alternating flashing lights. By setting the function module 6, the quick retrieval of the vehicle remote key 100 can be effectively assisted.

[0033] In some examples of the present invention, such as Figure 1 As shown, the vehicle remote key 100 may also include: multiple indicator lights 7, all of which are located in the housing 1 and connected to the circuit board 2. The multiple indicator lights 7 have different colors and correspond to different power ranges of the battery 3. The circuit board 2 is configured to illuminate the corresponding indicator light 7 according to the power of the battery 3.

[0034] The indicator lights 7 can be set to two, three or more, all of which are located in the housing 1 and connected to the circuit board 2. The multiple indicator lights 7 have different colors and correspond to different power ranges of the battery 3. The circuit board 2 is configured to light up the corresponding indicator light 7 according to the power level of the battery 3. This setting allows the occupants to effectively monitor the power information of the battery 3 and reduces the risk that the vehicle remote key 100 will not work due to insufficient power caused by the vehicle remote key 100 being in a dark area.

[0035] In some examples of the present invention, such as Figure 1 As shown, the multiple indicator lights 7 include: a first indicator light 71, a second indicator light 72, and a third indicator light 73. The first indicator light 71 corresponds to a power level greater than or equal to a first preset value, the second indicator light 72 corresponds to a power level less than the first preset value but greater than or equal to a second preset value, and the third indicator light 73 corresponds to a power level less than the second preset value.

[0036] In some embodiments of this application, the first preset value is 75%, and the second preset value is 20%. In some embodiments of this application, the first preset value is 70%, and the second preset value is 25%. In some embodiments of this application, the first indicator light 71 is green, the second indicator light 72 is yellow, and the third indicator light 73 is red. The first indicator light 71 corresponds to a battery level greater than or equal to the first preset value, the second indicator light 72 corresponds to a battery level less than the first preset value but greater than or equal to the second preset value, and the third indicator light 73 corresponds to a battery level less than the second preset value. This setting allows occupants to further monitor the battery level information of the battery 3 in real time and effectively, improving the occupants' control over the battery level of the vehicle remote key 100, and further reducing the risk that the vehicle remote key 100 will become unusable due to insufficient battery level caused by the vehicle remote key 100 being continuously in a dark area.

[0037] In some examples of the present invention, such as Figure 1 As shown, the vehicle remote key 100 may also include: a function button 8, which is located in the housing 1 and connected to the circuit board 2.

[0038] In this embodiment, there is at least one function button 8. In some embodiments of this application, there are multiple function buttons 8, such as a lock button 81, an unlock button 82, and a trunk button 83. In some embodiments of this application, there is only one function button 8, such as an integrated lock and unlock button (press once to lock, long press to unlock). The function buttons 8 are located in the housing 1 and connected to the circuit board 2. Passengers can press the corresponding function button 8 to perform corresponding operations on the vehicle, reducing the difficulty of vehicle operation.

[0039] In some examples of the present invention, such as Figure 1As shown, the housing 1 has a mounting port 12 that communicates with the receiving space 11, and the function button 8 is located in the mounting port 12.

[0040] The housing 1 has an installation port 12, which is connected to the receiving space 11. The function button 8 is located in the installation port 12. This arrangement makes the setting of the vehicle remote key 100 reasonable, facilitates the connection of the function button 8 to the circuit board 2, and makes it easier for the occupant to press the corresponding function button 8 to perform corresponding operations on the vehicle, further reducing the difficulty of operating the vehicle.

[0041] In some examples of the present invention, such as Figure 1 As shown, there are multiple function buttons 8, and the number of mounting ports 12 is the same as that of function buttons 8 and they correspond one-to-one.

[0042] The function buttons 8 are multiple, for example, two, three, or more. In some embodiments of this application, the function buttons 8 include a lock button 81, an unlock button 82, and a trunk button 83. The number of mounting ports 12 is the same as the number of function buttons 8, and each mounting port 12 corresponds one-to-one with a function button 8. That is, one mounting port 12 corresponds to one function button 8. This improves the rationality of the vehicle remote key 100's design, facilitating the connection of multiple function buttons 8 to the circuit board 2 so that each function button 8 can perform its corresponding function.

[0043] In some examples of the present invention, such as Figure 1 As shown, the housing 1 has through holes 13, which are arranged at intervals with the receiving space 11.

[0044] The housing 1 has a through hole 13. In some embodiments of this application, the through hole 13 is configured as a key fob through hole. The through holes 13 and the receiving space 11 are arranged at intervals to improve the sealing of the housing 1, further improve the waterproof and dustproof effect of the vehicle remote key 100, and further extend the service life of the vehicle remote key 100.
