Description

Technical Field

[0001] This utility model relates to a vehicle digital key with an adjustable face recognition module, belonging to the technical field of accessories or systems for preventing unauthorized use of vehicles. Background Technology

[0002] Currently, most commercial vehicle and bus fleets still use traditional mechanical keys to start and operate the vehicles. Passing these keys during shift changes is cumbersome. Some public vehicles are parked in uncontrolled areas at night, with the keys left inside the vehicle, posing a risk of unauthorized use by outsiders. Ensuring the authenticity and legality of drivers' identities is a challenge in fleet management, especially with drivers from large fleets or third-party contractors, where unauthorized use of vehicles by outsiders is possible. Furthermore, when there is a shortage of drivers or drivers are on leave, fleets may need temporary or replacement drivers, and quickly verifying the identities of these drivers is a difficult task.

[0003] In-vehicle digital keys perfectly solve the above problems. Through digital keys and biometric recognition technology (fingerprint unlocking + facial recognition unlocking), they transform the authorization of traditional physical keys into digital authorization, thereby facilitating fleet managers' effective control over vehicle driving or usage permissions. Currently, in-vehicle digital keys are beginning to replace traditional mechanical keys, improving vehicle security and fleet operational efficiency. When rapid vehicle movement is required, mechanical keys are unnecessary; the digital key system allows multiple site managers to simultaneously have starting permissions, enabling immediate vehicle activation and minimizing unnecessary losses and impacts.

[0004] Current vehicle digital keys are typically installed on the dashboard to the left or right of the steering wheel in the driver's cabin. A vehicle digital key includes a housing and a facial recognition module mounted on the housing; some also include fingerprint and card recognition modules. For the facial recognition module, its position is fixed after installation. However, different drivers have different heights, and when seated in the driver's seat, the facial recognition module may not be able to capture the driver's face precisely. If it cannot capture the face, the driver needs to adjust their posture to allow the facial recognition module to capture the image correctly. This not only affects recognition efficiency but also the driving experience. Utility Model Content

[0005] The purpose of this invention is to provide a vehicle digital key with an adjustable face recognition module to solve the problem that the face recognition module of existing vehicle digital keys is fixed in position, cannot capture the faces of drivers of different heights, and requires the driver to adjust their posture for recognition, which affects the recognition efficiency and driving experience.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An adjustable facial recognition module for vehicle digital keys includes a housing and a facial recognition module mounted on the housing. The facial recognition module is hinged to the housing via a hinge structure. The hinge structure is a universal ball joint structure, allowing the facial recognition module to swing at least up and down when force is applied, or the hinge structure is a unidirectional hinge structure with the hinge axis extending in the left-right direction, allowing the facial recognition module to swing up and down when force is applied. The hinge structure has a damping force that self-locks to a position after the facial recognition module swings.

[0007] The beneficial effects of the above technical solution are as follows: This utility model is an improved invention, further limiting the installation method of the face recognition module. Specifically, the face recognition module is hinged to the housing via a hinge structure, and the hinge structure is a universal ball joint structure, allowing the face recognition module to swing up and down when force is applied. Alternatively, the hinge structure can be a unidirectional hinge structure with the hinge axis extending in the left-right direction, allowing the face recognition module to swing up and down when force is applied. This allows the vertical angle of the face recognition module to be changed. For taller drivers, it swings upward, and for shorter drivers, it swings downward, thus meeting the face recognition needs of drivers of different heights. Drivers do not need to adjust their posture, resulting in higher recognition efficiency and no impact on the driving experience. Simultaneously, the hinge structure has a damping force that self-locks the face recognition module after it swings, thus fixing the position of the face recognition module after adjustment and ensuring normal face recognition operation.

[0008] Furthermore, the hinge structure is the universal ball joint structure described above. The face recognition module includes a module body and a connector connected to the module body. The end of the connector is provided with a ball head. The housing is provided with a mounting groove for installing the face recognition module with the groove facing forward.

A clamping member that cooperates with the ball concave surface to press the ball head is also installed in the mounting groove.

[0009] Furthermore, the connector is connected to one of the upper, lower, left, or right sides of the module body, with the concave spherical surface facing forward. The clamping member is a pressure plate fixedly connected to the bottom wall of the mounting groove, and the pressure plate is provided with a concave spherical surface that matches the ball head.

[0010] Furthermore, the pressure plate is fixed to the bottom wall of the mounting groove by adjusting screws, which adjust the damping force by adjusting the clamping force on the pressure plate.

[0011] Furthermore, a panel is fixed to the front end of the housing, the panel covers the ball head and the pressure plate, and the panel has a main body protrusion for exposing the main body of the module and a screw protrusion for exposing the adjusting screw.

[0012] Furthermore, the connector is connected to the lower side of the module body, the bottom wall of the mounting slot forms an upper limiting structure for limiting the upward swing limit of the face recognition module, and the opening of the mounting slot forms a lower limiting structure for limiting the downward swing limit of the face recognition module; or the connector is connected to the upper side of the module body, the bottom wall of the mounting slot forms a lower limiting structure for limiting the downward swing limit of the face recognition module, and the opening of the mounting slot forms an upper limiting structure for limiting the upward swing limit of the face recognition module.

[0013] Furthermore, the left sidewall of the mounting slot forms a left limiting structure to restrict the leftward swing limit of the face recognition module, and the right sidewall of the mounting slot forms a right limiting structure to restrict the rightward swing limit of the face recognition module.

[0014] Furthermore, the connector is connected to the lower side of the module body, and a protruding plate is provided on the top surface of the module body. A clearance groove is provided on the top wall of the housing, with the slot facing forward so that the protruding plate can enter when the face recognition module swings upward.

Detailed Implementation

[0019] To address the technical problems existing in the prior art, the basic concept of this utility model is to mount the face recognition module on the housing via a hinge structure. The hinge structure is either a universal ball joint or a unidirectional hinge structure with the hinge axis extending in the left-right direction. This allows the face recognition module to swing up and down when force is applied, accommodating face shooting and recognition for drivers of different heights. Furthermore, the damping force of the ball joint structure enables the face recognition module to self-lock its position after swinging, ensuring that face recognition can proceed normally.

[0020] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0021] The implementation method of the adjustable face recognition module vehicle digital key (hereinafter referred to as vehicle digital key) in this utility model is as follows: like Figure 1 , Figure 2 and Figure 3 As shown, the vehicle digital key includes a housing, on which are installed a fingerprint recognition module 5, a card swipe recognition module 6, and a facial recognition module 10, enabling driver identification through three methods. For permanent drivers in the fleet, since facial and fingerprint information, as well as employee card information, are already recorded, identification can be performed through any of the above methods. However, for temporary or substitute drivers, facial information is often only sent to the management platform, so only facial recognition can be performed. Regardless of whether the driver is permanent or temporary, when using facial recognition for identification, due to the different heights of different drivers, the facial recognition module may not be able to capture the driver's face precisely when the driver is seated. If it cannot capture the face, the driver needs to adjust their posture so that the facial recognition module can capture the face properly, which not only affects recognition efficiency but also the driving experience.

[0022] Based on the aforementioned problems, this invention improves the installation method of the face recognition module by hingedly mounting the face recognition module 10 onto the housing via a hinge structure. Specifically, in this embodiment, the hinge structure is a universal ball joint, allowing the face recognition module 10 to swing up and down when force is applied. For taller drivers, it swings upwards, and for shorter drivers, it swings downwards, thus accommodating face recognition for drivers of different heights. This eliminates the need for drivers to adjust their posture, resulting in higher recognition efficiency and no impact on the driving experience. Furthermore, the hinge structure possesses a damping force that self-locks the face recognition module 10 after it swings, preventing displacement during driving. In other words, the face recognition module 10 is not arbitrarily swayed; its position is fixed after adjustment, ensuring normal face recognition operation.

[0023] Of course, due to the presence of the universal ball joint structure, the face recognition module 10 can also swing left and right. This not only gives the face recognition module 10 a larger adjustment range, but also allows for different adjustments during vehicle assembly. If the vehicle digital key is installed on the dashboard to the left of the steering wheel in the driver's cabin, the face recognition module 10 can be directly swung to the right to align with the driver's seat. If the vehicle digital key is installed on the dashboard to the right of the steering wheel, the face recognition module 10 can be directly swung to the left to align with the driver's seat. Once the driver is in position, if the angle is just right, there is no need to adjust the face recognition module 10, making it more convenient to use.

[0024] Of course, due to the presence of the universal ball joint structure, the face recognition module 10 is not limited to swinging in four directions: up, down, left, and right. For example, it can also swing to the upper left, lower left, upper right, and lower right, making the adjustment very flexible. The purpose is to conveniently align the face recognition module 10 with the driver's face.

[0025] In other embodiments, the hinge structure can also be a unidirectional hinge structure with the hinge axis extending in the left-right direction. In this case, when force is applied, the face recognition module can only swing up and down, and after swinging, it can self-lock its position using the damping force of the hinge structure. This also solves the problem that the face recognition module cannot adapt to the face recognition of drivers of different heights. In this case, if the vehicle digital key is installed on the dashboard to the left or right of the steering wheel in the driver's cabin, the left-right angle of the vehicle digital key must be determined during installation so that face recognition of drivers of different heights can be completed simply by adjusting up and down. Of course, if the vehicle digital key is installed on the dashboard directly opposite the steering wheel, there is no need to consider the left-right angle; the vehicle digital key can simply face the driver's seat.

[0026] Specifically in this embodiment, such as Figure 3 As shown, the face recognition module 10 includes a module body 101 and a connector 102 connected to the module body 101. The connector 102 has a ball-shaped end 103. The module body 101 actually has a shell, and the connector 102 and ball-shaped end 103 are connected to the shell. Furthermore, the connector 102 is connected to one of the following sides of the module body 101: top, bottom, left, or right. In this embodiment, it is connected to the bottom side of the module body 101. Also, the module body 101 has a cuboid structure, and the connector 102 is connected to the middle of the module body 101 along its length.

[0027] The vehicle digital key housing contains a PCBA4, and the fingerprint recognition module 5, card swipe recognition module 6, and face recognition module 10 are all connected to the PCBA4. The vehicle digital key housing consists of a front housing 1 and a rear housing 2, which are fixed together by fastening screws 7. The front side of the vehicle digital key is actually the driver's side, which is exactly opposite to the front-rear direction of the vehicle. However, this orientation is easy to understand when describing the vehicle digital key itself.

[0028] The front housing 1 is provided with a mounting slot for installing the face recognition module 10, with the slot facing forward, such as... Figure 3 and Figure 4 As shown, the mounting slot specifically includes a main mounting slot 11 for mounting the main body 101 of the module and a ball head mounting slot 12 for mounting the ball head 103. A partition 13 is provided between the main mounting slot 11 and the ball head mounting slot 12. A passage 131 for the connector 102 to pass through is provided on the partition 13. The passage 131 is a U-shaped opening, which can simultaneously meet the movement needs of the connector 102.

[0029] The bottom wall of the ball head mounting groove 12 is provided with a ball concave surface 121 that is adapted to the ball head 103. A clamping member that cooperates with the ball concave surface 121 to press the ball head 103 is also installed in the ball head mounting groove 12. The clamping member realizes the ball joint installation of the face recognition module 10 on the one hand, and changes the damping force of the universal ball joint structure by adjusting the clamping force on the ball head 103 on the other hand.

[0030] Specifically, the concave surface 121 of the sphere is arranged facing forward, as shown below. Figure 3 As shown, the clamping member is a pressure plate 9 that is fixedly connected to the bottom wall of the ball head mounting groove 12. The pressure plate 9 is provided with a concave spherical surface that is adapted to the ball head 103. The concave spherical surface and the concave spherical surface 121 cooperate to clamp the ball head 103.

[0031] The pressure plate 9 is fixed to the bottom wall of the ball head mounting groove 12 by adjusting screws 8. The middle part of the pressure plate 9 is a bulging structure, and the inner wall of the bulging structure is the concave spherical surface mentioned above. Both ends of the pressure plate 9 are provided with screw holes for the adjusting screws 8 to pass through, that is, there are two adjusting screws 8 in total. The two adjusting screws 8 adjust the damping force mentioned above by adjusting the clamping force on the pressure plate 9, which is relatively convenient to operate.

[0032] In fact, the hinge structure has a damping force when the adjusting screw 8 is installed for the first time, that is, when the face recognition module 10 is installed for the first time. In the later use, it is not necessary to adjust the damping force frequently. Only after long-term use, when the adjusting screw 8 becomes loose due to vehicle vibration and the face recognition module 10 can no longer be fixed in position, is it necessary to readjust the adjusting screw 8 to adjust the damping force.

[0033] Of course, depending on the actual situation, for example, if the adjusting screw 8 is installed too tightly and the damping force is too large when the vehicle digital key is manufactured, the adjusting screw 8 can be loosened appropriately when the vehicle digital key is installed on the vehicle; or if the adjusting screw 8 was originally installed too loose, it can be tightened appropriately. Ultimately, it is advisable that when a person applies appropriate force to the face recognition module 10, the face recognition module 10 can swing smoothly and lock itself in position after swinging.

[0034] In addition, the vehicle digital key also includes a panel 3 fixed to the front end of the front housing 1. In this embodiment, the panel 3 is a silicone panel, but in other embodiments it can also be a metal panel. The panel 3 covers the ball head 103 and the pressure plate 9, which is more aesthetically pleasing.

[0035] like Figure 1 and Figure 3As shown, panel 3 has a main body opening 31 for exposing the main body 101 of the module and a screw opening 32 for exposing the adjusting screws 8. The main body opening 31 is a U-shaped opening and the screw opening 32 is a round hole. There are two screw openings to ensure that the normal use function of the face recognition module 10 is not affected, and at the same time, to ensure that each adjusting screw 8 can be operated.

[0036] In addition, for convenient fingerprint recognition, panel 3 is equipped with a fingerprint recognition port 33 that exposes the fingerprint recognition module 5. A card swipe indicator 34 is also designed on panel 3 to clearly indicate the card swiping location for the vehicle digital key. Of course, besides these, panel 3 also features other function buttons and indicators, which are all basic configurations of the vehicle digital key.

[0037] In this embodiment, the maximum angle of the face recognition module 10's upward, downward, leftward, and rightward swings is 15°, which is achieved through its structure and dimensions. Figure 1 and Figure 2 The image shows the face recognition module 10 in the neutral position (i.e., not swinging up, down, left, or right). At this time, the front end of the face recognition module 10 protrudes from the front end of the front housing 1 and is parallel to the front end of the front housing 1, making it convenient for a person to apply force to the face recognition module 10.

[0038] like Figure 5 and Figure 6 As shown, the face recognition module 10 is in its extreme upward swing position. At this time, the bottom wall of the main mounting slot 11 stops the face recognition module 10, and the stopping position is... Figure 6 In the A section, the face recognition module 10 is prevented from swinging further upward. Therefore, the bottom wall of the main mounting groove 11 constitutes an upper limiting structure for limiting the upward swing limit of the face recognition module 10.

[0039] At the same time, combined Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, a protruding plate 104 is provided on the top surface of the module body 101. A clearance groove 111 is provided on the top wall of the front housing 1 (i.e., on the groove side wall above the main body mounting groove 11), with the groove opening facing forward to allow the protruding plate 104 to enter when the face recognition module 10 swings upward. The bottom wall of the clearance groove 111 is used to stop and cooperate with the protruding plate 104 to limit the extreme position of the face recognition module 10's upward swing. That is, there is also a stopping position B between the protruding plate 104 and the bottom wall of the clearance groove 111. Figure 6 As shown, when the face recognition module 10 swings upward to its limit position, there are two limit points.

[0040] Since the rotating part of the face recognition module 10 is at the bottom, it is relatively easy to swing the face recognition module 10 upwards by simply pressing the top of the face recognition module 10. However, it is not easy to swing the face recognition module 10 downwards. In this case, the protruding plate 104 can be used as an operating plate, and the face recognition module 10 can be swung downwards by holding the protruding plate 104 with your hand.

[0041] like Figure 7 and Figure 8 As shown, the face recognition module 10 is in its downward swing limit position. At this time, the lower side of the slot opening of the main body mounting groove 11 stops the face recognition module 10, and the stopping position is... Figure 8 The C in the middle prevents the face recognition module 10 from swinging further downward, so the slot of the main body mounting groove 11 constitutes a lower limiting structure for limiting the downward swing limit of the face recognition module 10.

[0042] Of course, in other embodiments, if the connector 102 is connected to the upper part of the module body 101, the rotating part of the face recognition module 10 is at the top. In this case, the bottom wall of the main body mounting groove 11 forms a lower limiting structure for limiting the downward swing limit of the face recognition module 10, and the groove opening of the main body mounting groove 11 forms an upper limiting structure for limiting the upward swing limit of the face recognition module 10.

[0043] The left and right swaying of the face recognition module 10 can be achieved simply by pressing, making operation quite convenient. For example... Figure 9 and Figure 10 As shown, the face recognition module 10 is at its extreme leftward swing position. At this time, the left sidewall of the main mounting slot 11 stops the face recognition module 10, and the stopping position is... Figure 10 The D in the figure prevents the face recognition module 10 from swinging further to the left. Therefore, the side wall of the slot on the left side of the main body mounting slot 11 constitutes a left limiting structure for limiting the leftward swing limit of the face recognition module 10.

[0044] like Figure 11 and Figure 12 As shown, the face recognition module 10 is at its extreme rightward swing position. At this time, the right sidewall of the main mounting slot 11 stops the face recognition module 10, and the stopping position is... Figure 12 The E in the figure prevents the face recognition module 10 from swinging further to the right. Therefore, the right side wall of the main mounting slot 11 constitutes a right limiting structure for limiting the rightward swing limit of the face recognition module 10.

[0045] Of course, in other embodiments, if the main mounting groove 11 is relatively shallow and the groove width is sufficient, the left and right swing of the face recognition module 10 can not contact the groove sidewalls on the left and right sides of the main mounting groove 11. At this time, when the face recognition module 10 swings to the left and right to the extreme position, it stops against the bottom wall of the main mounting groove 11. Therefore, the bottom wall of the main mounting groove 11 simultaneously constitutes the left limiting structure and the right limiting structure.

[0046] By swinging the face recognition module 10 in various directions, it can cover the face recognition of drivers in all scenarios, adapt to drivers of different heights, improve recognition efficiency, and is more in line with human factors engineering, thus having strong promotion and application value.

[0047] In other embodiments of the vehicle digital key with adjustable face recognition module: the main mounting slot and the ball head mounting slot can be directly connected, and no partition is set in the middle.

[0048] In other embodiments of the vehicle digital key with adjustable face recognition module: the main body of the module can also be a cube with consistent length and width, or a cylindrical block.

[0049] In other embodiments of the vehicle digital key with adjustable face recognition module: when the connector is connected to the lower side of the module body, the protrusion plate may not be provided on the top surface of the module body. Only the bottom wall of the mounting groove is used to limit the extreme position of the face recognition module swinging upward. In this case, in order to facilitate the downward swing of the face recognition module, an operation notch can be reserved on the top wall of the front housing so that the hand can apply force to the face recognition module through the operation notch.

[0050] In other embodiments of the adjustable face recognition module vehicle digital key: when the connector is connected to the upper side of the module body, a protruding plate can be provided on the bottom surface of the module body, and an avoidance groove can be provided on the bottom wall of the housing to allow the protruding plate to enter when the face recognition module swings downward. Similarly, the bottom wall of the avoidance groove can cooperate with the protruding plate to limit the extreme position of the face recognition module's downward swing. Of course, in other embodiments, the protruding plate may not be provided on the bottom surface of the module body, and only the bottom wall of the mounting groove can be used to limit the extreme position of the face recognition module's downward swing. In this case, in order to facilitate the upward swing of the face recognition module, an operating notch can be reserved on the bottom wall of the front housing so that a hand can apply force to the face recognition module through the operating notch.

[0051] In other embodiments of the vehicle digital key with adjustable face recognition module: the vehicle digital key may not include an additional silicone panel, and the end plate of the front housing is the panel, in which case the ball head, pressure plate and adjusting screw are exposed.

[0052] In other embodiments of the vehicle digital key with adjustable face recognition module: the pressure plate can be glued and fixed to the bottom wall of the mounting groove. After the pressure plate is installed, the damping force is fixed and cannot be adjusted. In this case, in order to avoid the damping force from failing after long-term use, a rubber pad can be placed between the pressure plate and the ball head, or between the concave surface of the ball and the ball head.

[0053] In other embodiments of the adjustable face recognition module in a vehicle digital key: when the module body is a cuboid structure, the connector can also be connected to one end along the length of the module body, such as the left or right end. Of course, even if the module body is a cube, the connector can still be connected to either the left or right end.

[0054] In other embodiments of the adjustable face recognition module vehicle digital key: the connector can also be connected to the middle of the back of the module body. In this case, a protruding post is provided on the bottom wall of the mounting groove, the end of the protruding post has a spherical concave surface, and the outer periphery of the protruding post has external threads. At the same time, a nut cap is fitted on the outside of the connector. The nut cap is engaged with the external threads on the protruding post and presses down on the ball head. The tighter the nut cap is tightened, the greater the damping force, and vice versa. The ball joint structure is similar to the hinge structure on an adjustable mobile phone holder. The nut cap acts as a clamping element. In order to facilitate the adjustment of the nut cap, at least one side of the mounting groove needs to be an open structure so that a hand can be inserted. Of course, in other embodiments, the ball head can also be set on the bottom wall of the mounting groove. In this case, the end of the connector of the face recognition module has a spherical concave surface, and the nut cap is threadedly connected to the connector, with the same principle as above.

[0055] In other embodiments of the vehicle digital key with adjustable face recognition module: when the hinge structure is a one-way hinge structure with the hinge axis extending in the left and right direction, two hinge ear plates can be set on the housing, the connector of the face recognition module extends between the two ear plates, and bolts are used to pass through the two hinge ear plates and the connector and connect the nuts. The tightness of the nuts determines the damping force of the hinge structure.

[0056] In other embodiments of the vehicle digital key with adjustable face recognition module: there can be only one housing, with a front plate at the front end and a rear plate fixed at the rear end to form a receiving cavity.

[0057] In other embodiments of the vehicle digital key with an adjustable face recognition module: the housing may not have a mounting slot, and the hinge structure is located on the outside of the housing, not on the inside. In this case, the face recognition module is completely exposed on the outside of the housing after installation, allowing for a wider range of adjustment.

[0058] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. The patent protection scope of the present utility model shall be determined by the claims. Similarly, any equivalent structural changes made based on the description and drawings of the present utility model shall also be included within the protection scope of the present utility model.
