Description

Technical Field

[0001] This utility model relates to the field of vehicles and relates to a posture recognition unlocking device. Background Technology

[0002] Currently, cars and motorcycles are commonly unlocked using physical keys, electronic keys using near-field communication (RFID), or mobile apps. However, the most common problem is forgetting to bring the physical key or electronic key.

[0003] Furthermore, unlocking via electronic keys or mobile apps also requires the vehicle's equipment to work in conjunction with Bluetooth or near-field sensors. Overall, this is relatively energy-intensive. Utility Model Content

[0004] In view of this, this utility model proposes an unlocking method that does not require physical sensing. The inventors have considered password, fingerprint, and facial recognition functions. However, fingerprint recognition is often ineffective due to static electricity on the vehicle body, while facial recognition or passwords typically require touchscreens or cameras, resulting in higher overall costs. Furthermore, since vehicles are often located outdoors, the lifespan of electronic products is easily damaged by heat or humidity.

[0005] Here, a posture recognition unlocking device is provided, installed on a vehicle body. The posture recognition unlocking device includes a millimeter-wave radar transceiver, a microprocessor, and a memory element. The millimeter-wave radar transceiver continuously generates millimeter-wave radar waves into the space outside the vehicle body and receives reflected waves generated when the millimeter-wave radar waves are blocked. The microprocessor is electrically connected to the millimeter-wave radar transceiver and generates unlocking pattern information according to the continuous changes in the position and area of ​​the received reflected waves at a specific time. The memory element is electrically connected to the microprocessor and stores preset unlocking pattern information. When the microprocessor accesses the preset unlocking pattern information and determines that it matches the unlocking pattern information, it generates an actuation signal to a locking device on the vehicle body to unlock it.

[0006] Preferably, the vehicle body is provided with a groove, and the millimeter radar transceiver is installed in the groove.

[0007] More specifically, preferably, the depth of the groove is inversely related to the transmission frequency of the millimeter-wave radar transceiver.

[0008] Furthermore, preferably, the depth of the groove is matched to the transmission frequency of the millimeter-wave radar transceiver.

[0009] Preferably, the transmission frequency of the millimeter radar transceiver is 40 GHz to 90 GHz.

[0010] Preferably, the depth of the groove is greater than or equal to 1.5 cm.

[0011] Preferably, the vehicle body is provided with a pattern that faces the space where the millimeter radar transceiver transmits millimeter radar waves.

[0012] Preferably, the millimeter radar transceiver acquires targets in space and generates continuous changes in reflected waves based on the continuous movement of the targets.

[0013] More specifically, the continuous motion of the target object is selected from a group consisting of finger taps, finger swipes, and palm coverings.

[0014] Preferably, the vehicle body is a locomotive, and the millimeter radar transceiver is installed in the front shell of the locomotive.

[0015] Preferably, the vehicle body is a car, and the millimeter radar transceiver is installed on the car door handle.

[0016] Due to the adoption of the above technical solution, this utility model has the following beneficial effects: As described in the foregoing embodiments, by utilizing a low-power, low-cost millimeter-wave radar transceiver, it can be used in vehicles that are located in outdoor environments for extended periods. This enables the vehicle to be unlocked using gestures without any physical device, providing users with operational convenience. Attached Figure Description

Detailed Implementation

[0023] Figure 1 A cross-sectional view showing the posture recognition unlocking device mounted on a portion of the vehicle body. Figure 2 Draw a block diagram showing the gesture recognition unlocking device. For example... Figure 1 and Figure 2 As shown, the attitude recognition unlocking device 1 is installed on the vehicle body 100. The attitude recognition unlocking device 1 includes a millimeter radar transceiver 10, a microprocessor 20, and a memory element 30. The millimeter radar transceiver 10 continuously generates millimeter radar waves T into the space outside the vehicle body 10 and receives reflected waves R generated when the millimeter radar waves T are blocked. The microprocessor 20 is electrically connected to the millimeter radar transceiver 10 and generates unlocking pattern information according to the continuous change C of the position and area of ​​the received reflected wave R at a specific time.

[0024] More specifically, the millimeter radar transceiver 10 includes a plurality of transmitters 11 and a plurality of receivers 13. The microprocessor 20 simulates a corresponding coordinate matrix based on the contacts connected to the transmitters 11 and receivers 13, and generates a 0 / 1 signal based on whether a reflected wave R is received, thereby generating a dot pattern in the coordinate matrix. For a period of time, such as 15 seconds, the continuous change C of the dot pattern generated in the coordinate matrix is ​​used as unlocking pattern information.

[0025] The memory element 30 is electrically connected to the microprocessor and stores preset unlock pattern information. When the microprocessor 20 accesses the preset unlock pattern information P and determines that it matches the unlock pattern information, it generates an actuation signal E to the locking device of the vehicle body 100 (not shown in the figure) to unlock it.

[0026] See you again Figure 1 The posture recognition unlocking device 1 is installed in a recess 110 of the vehicle body 100 and then covered by a non-conductive cover 120 to further prevent the influence of the external environment on the posture recognition unlocking device 1 and further improve the service life of the posture recognition unlocking device 1. However, this is only an example and not intended to limit the scope. In practice, it can also be directly installed on the vehicle body.

[0027] Furthermore, the frequency of the millimeter-wave radar transceiver 10 directly affects its resolving power to determine the continuous change C of the position and area of ​​the reflected wave R. For example, a 60GHz millimeter-wave radar transceiver 10 has a resolving power of 1.5 cm, meaning it can clearly resolve signals at distances greater than 1.5 cm. Therefore, when using the surface of the vehicle body 100 as the operating reference surface, the depth of the groove 110 is typically at least greater than the minimum resolving power. Thus, the depth of the groove 110 is inversely related to the transmission frequency of the millimeter-wave radar transceiver 10. That is, a deeper groove 110 is used when using a millimeter-wave radar transceiver 10 with a lower transmission frequency. Considering the depth of the vehicle body 10, the groove 110 is not dug indefinitely; typically, the depth of the groove 110 is matched to the transmission frequency of the millimeter-wave radar transceiver 10. For example, in some embodiments, the transmission frequency of the millimeter-wave radar transceiver 10 is 40GHz to 90GHz. The depth of the groove 110 is greater than or equal to 1.5 cm.

[0028] Figure 3 A top view of a portion of the vehicle body of one embodiment is shown. Figure 4 A schematic diagram illustrating the posture recognition unlocking device in use. (Example) Figure 3 As shown, the vehicle body 100 is a motorcycle, and the millimeter-wave radar transceiver 10 is mounted on the front housing 130 of the motorcycle, for example, in the housing next to the handlebars. A plurality of patterns 140 are provided on the vehicle body 100, with the patterns 140 facing the space where the millimeter-wave radar transceiver 10 transmits millimeter-wave radar waves T. Here, two dot patterns 141 are used as an example; these can be achieved through laser engraving or stickers, and are only used to define the effective space for the millimeter-wave radar transceiver 10 to transmit and sense millimeter-wave radar waves T.

[0029] like Figure 4 As shown, the millimeter-wave radar transceiver 10 acquires a target object 200 in space, such as a user's hand, and generates a continuous change C in the reflected wave R based on the continuous movement of the target object 200 in space. For example, touching or simply clicking the dot pattern 141 with one or more fingers, sliding left or right between two dot patterns 141, or covering the space between two dots with the palm, etc. In this way, by moving in space through the gesture, the millimeter-wave radar T is blocked, and the reflected wave R is generated. For example, a combination of four actions, such as clicking the right dot pattern 141, sliding left, clicking two dot patterns 141, and sliding right, serves as the unlock pattern information, that is, as the user's unlock password.

[0030] By unlocking the password in space using virtual clicks or swipes, issues such as password skimming or fingerprints left over time can be avoided, thus further enhancing password security.

[0031] Figure 5 A side view of a portion of the vehicle body according to another embodiment is shown. (See diagram.) Figure 5 As shown, different Figure 3 The point is that the vehicle body 100 is a car, and the millimeter radar transceiver 10 is installed on the car door handle 150. However, the above is only an example and not intended to be limiting.

[0032] In summary, by utilizing the low-power, low-cost millimeter-wave radar transceiver 10, it can be used in the vehicle body 100, which is located in an outdoor environment for a long time, to achieve the function of unlocking without any physical device, using gestures and postures, thus providing users with operational convenience.
