Description

Technical Field

[0001] This invention discloses an electronic device, and particularly relates to a camera device. Background Technology

[0002] With the development of technology, camera devices are increasingly being used in fields such as personal electronics, automobiles, and medicine to capture external images. For example, camera devices (such as dashcams) can be installed in vehicles to continuously record images, capture ambient sounds, and sense vibrations inside the vehicle while driving.

[0003] Generally, camera devices are mainly installed and fixed using locking elements. However, if the camera device is not properly and stably locked by the locking elements, it is prone to vibration or shaking during use. This can lead to an inability to fix the shooting angle, an inability to accurately detect vibrations, and the recording of its own vibration noise. Furthermore, the camera device is also prone to falling off due to continuous vibration or shaking, resulting in damage to the camera device. Summary of the Invention

[0004] In view of the above, in one embodiment, a camera device is provided, including a housing, a linkage, a sensor, a reset member, a locking device, and a prompting module. The housing includes a keyhole and a receiving chamber, the keyhole communicating with the receiving chamber. The linkage is movably disposed within the receiving chamber, and includes a pressure-receiving portion and a triggering portion, the pressure-receiving portion corresponding to the keyhole. The sensor is disposed within the receiving chamber and adjacent to the triggering portion of the linkage. The reset member is disposed within the receiving chamber, and the reset member drives the linkage to a first position, the first position preventing the triggering portion from triggering the sensor. The locking device is movably assembled to the keyhole; when the locking device moves relative to the keyhole to the correct locking position, the locking device presses against the pressure-receiving portion to move the linkage from the first position to a second position, the second position causing the triggering portion to trigger the sensor and generate a correct locking signal. The prompting module is connected to the sensor, and the prompting module receives and issues a prompt message based on the correct locking signal.

[0005] In some embodiments, the pressure-bearing portion also extends into the keyhole.

[0006] In some embodiments, the pressure-receiving portion is a protruding post, and the pressure-receiving portion and the locking fastener are coaxially arranged. In some embodiments, the sensor includes a light emitting unit and a light receiving unit, which are respectively disposed on opposite sides of the trigger portion.

[0007] In some embodiments, when the linkage is in the first position, the triggering part is not located between the light emitting unit and the light receiving unit, so that the light emitted by the light emitting unit is incident on the light receiving unit. When the linkage is in the second position, the triggering part is blocked between the light emitting unit and the light receiving unit, so that the light does not incident on the light receiving unit and triggers the sensor.

[0008] In some embodiments, the sensor is a push switch. When the linkage is in the first position, the trigger part maintains a distance from the sensor. When the linkage is in the second position, the trigger part presses against and triggers the sensor.

[0009] In some embodiments, the sensor includes a first sensing element and a second sensing element. The first sensing element is fixed to the trigger portion of the linkage, and the second sensing element is fixed in the accommodating cavity and kept at a distance from the first sensing element. One of the first sensing element and the second sensing element is a Hall sensor, and the other of the first sensing element and the second sensing element is a magnetic body.

[0010] In some embodiments, the reset element is an elastic element or a magnetic component.

[0011] In some embodiments, the linkage moves linearly from a first position to a second position.

[0012] In some embodiments, a limiting seat is further provided in the accommodating cavity. The limiting seat includes an annular wall and a guide groove formed in the annular wall, and the linkage is accommodated in the guide groove.

[0013] In some embodiments, the linkage includes a pivot portion pivotally disposed within the receiving cavity.

[0014] In some embodiments, the pivot portion is located at one end of the linkage, the trigger portion is located at the other end of the linkage, and the pressure-bearing portion is located between the pivot portion and the trigger portion.

[0015] In some embodiments, the prompting module includes a display unit, a sound output unit, an indicator light unit, or a combination of at least two of them.

[0016] In some embodiments, the prompting module includes a wireless communication unit that wirelessly transmits prompt messages to the user device.

[0017] In some embodiments, when the prompting module does not receive the correct locking signal, the prompting module issues another prompting message, which is different from the original prompting message.

[0018] In some embodiments, the camera device further includes a bracket having a through hole corresponding to a keyhole, through which a locking fastener passes to be engaged with the keyhole.

[0019] In summary, according to the camera device of the present invention, when the locking fastener moves to the correct locking position, the sensor can be triggered by the linkage to generate a correct locking signal, which in turn causes the prompting module to issue a prompt message. Therefore, the user can clearly know from the prompt message that the locking fastener has been correctly locked in place, thus avoiding the situation where the camera device vibrates or shakes during use due to insecure installation of the locking fastener, and enabling the camera device to function normally.

[0069] Various embodiments are described in detail below; however, these embodiments are merely illustrative and do not limit the scope of protection intended for this invention. Furthermore, some elements are omitted in the drawings of the embodiments to clearly show the technical features of the invention. The same reference numerals will be used to denote the same or similar elements in all drawings.

[0070] Figure 1 This is a perspective view of the first embodiment of the camera device of the present invention. Figure 2 This is an exploded perspective view of the first embodiment of the camera device of the present invention. Figure 3 for Figure 1 A cross-sectional view along line segment 3-3. Figure 4 This is a cross-sectional view of the first embodiment of the camera device of the present invention in the correct locking position. Figures 1 to 3 As shown, the camera device 1 can be a dashcam installed in a vehicle, enabling the vehicle to continuously capture images, record ambient sounds, and sense vibrations inside the vehicle while driving. In some embodiments, the camera device 1 can also be an IP camera / Network camera, closed-circuit television (CCTV), or analog surveillance camera, and the camera device 1 can be installed in various locations (such as nurseries, offices, shops, highways, etc.) for security monitoring or recording of personnel activities.

[0071] like Figures 1 to 3 As shown, in this embodiment, the camera device 1 includes a housing 10, a linkage 20, a sensor 30, a reset component 40, and a locking device 50. The housing 10 is a hollow housing, and includes a locking hole 11 and a receiving chamber 15 located inside the housing 10. The receiving chamber 15 is used to accommodate the components required by the camera device 1. In this embodiment, the locking hole 11 is an internally threaded hole, and the locking hole 11 penetrates one side of the housing 10 along an axial direction A to communicate with the receiving chamber 15.

[0072] like Figure 2 and Figure 3 As shown, in this embodiment, the housing 10 is assembled from multiple shell plates 101 and 102, and the housing 10 also has a through hole 12, which and the lock hole 11 can be located on the same side of the housing 10 (e.g., Figure 2 (As shown) or on different sides. A circuit board 16 is provided inside the accommodating chamber 15, and a camera lens 17 is provided on the circuit board 16. The camera lens 17 is inserted into the through hole 12, so that one end of the camera lens 17 can be exposed outside the housing 10 to capture external images.

[0073] like Figure 2 and Figure 3As shown, the linkage 20 is movably disposed within the accommodating chamber 15. For example, the linkage 20 can move linearly or oscillate relative to the housing 10, which will be described in detail later. The linkage 20 can be a plate, block, or rod, etc. The linkage 20 includes a pressure-receiving part 21 and a triggering part 25, and the pressure-receiving part 21 corresponds to the lock hole 11. In this embodiment, the pressure-receiving part 21 is a protrusion disposed on the first side 201 of the linkage 20 near the lock hole 11, and the pressure-receiving part 21 and the lock hole 11 are coaxially disposed and extend into the lock hole 11. The triggering part 25 is a local area of ​​the second side 202 of the linkage 20 near the circuit board 16.

[0074] like Figure 2 and Figure 3 As shown, the reset member 40 and the sensor 30 are disposed within the accommodating chamber 15, and the reset member 40 is used to drive the linkage 20 to a first position. The number of reset members 40 can be one or more, and the reset member 40 can be an elastic element (e.g., a spring, elastic rubber, or elastic foam) or a magnetic component. In this embodiment, the reset member 40 is a spring and there are two of them. The two reset members 40 abut against the circuit board 16 and the linkage 20, and the two reset members 40 are respectively adjacent to opposite sides of the linkage 20. The linkage 20 can be positioned in the first position based on the elastic abutment of the two reset members 40 (e.g., ...). Figure 3 (as shown in the diagram). In the first position, the linkage 20 is positioned by its first side 201 near the lock hole 11 abutting against the housing 10. When the linkage 20 is subjected to a force toward the circuit board 16, it can move linearly toward the circuit board 16 and compress the two reset members 40 to store spring force. Thus, when the linkage 20 is released, it can return to the first position by the spring force stored in the reset members 40.

[0075] like Figure 2 and Figure 3 As shown, sensor 30 is adjacent to the trigger portion 25 of linkage 20, and sensor 30 can be a contact sensor or a non-contact sensor. In this embodiment, sensor 30 is disposed on circuit board 16 and corresponds to the trigger portion 25 of linkage 20. When linkage 20 is in the first position described above, the trigger portion 25 of linkage 20 and sensor 30 maintain a distance from each other and do not trigger sensor 30.

[0076] like Figure 2 and Figure 3 As shown, the locking fastener 50 is movably assembled to the lock hole 11. In this embodiment, the locking fastener 50 is a screw or bolt with external threads, and the camera device 1 also includes a bracket 70 having a through hole 71 corresponding to the lock hole 11. The locking fastener 50 passes through the through hole 71 to be screwed into the lock hole 11, and the locking fastener 50 can be moved relative to the lock hole 11 along the axial direction A by rotational operation. Figure 2As shown, the bracket 70 may have an assembly 72, such as a suction cup, adhesive layer or connector, so that the camera device 1 can be fixed to the dashboard or windshield of a vehicle by the assembly 72 of the bracket 70, or the camera device 1 can also be fixed to other objects (such as walls in various places) by the assembly 72 of the bracket 70.

[0077] like Figure 3 As shown, when the locking fastener 50 has not yet been tightened toward the housing 10, the locking fastener 50, the bracket 70, and the housing 10 are not yet in contact with each other. Figure 4 As shown, during assembly, the locking member 50 can be rotated and moved relative to the lock hole 11 towards the housing 10 (as indicated by arrow L1) to the correct locking position. The correct locking position refers to the position where the locking member 50, the bracket 70, and the housing 10 are firmly secured to each other without any wobbling. When the locking member 50 is in the correct locking position, it presses against the pressure portion 21 of the linkage 20, causing the linkage 20 to move linearly from the first position to the second position (as indicated by arrow L1). Figure 4 (As shown in the figure) When the linkage 20 is in the second position, the triggering part 25 can trigger the sensor 30 to generate a correct locking signal. For example, in this embodiment, the sensor 30 is a contact-type push switch. When the linkage 20 moves linearly from the first position to the second position, the triggering part 25 can press against the sensor 30 to trigger the sensor 30 and generate a correct locking signal.

[0078] like Figures 2 to 4 As shown, in this embodiment, a limiting seat 18 is also provided on the surface of the circuit board 16 facing the lock hole 11. The limiting seat 18 includes an annular wall 181 and a bottom wall 182. A guide groove 183 is formed between the annular wall 181 and the bottom wall 182. The linkage 20 is accommodated in the guide groove 183, so that when the linkage 20 is subjected to force and moves between the first position and the second position, the linkage 20 can be limited by the annular wall 181 to avoid displacement, thereby making the operation of the linkage 20 more stable and able to reliably trigger the sensor 30 to generate the correct locking signal. In addition, in this embodiment, the pressure-receiving part 21 of the linkage 20 is located at the center of the first side 201, and the pressure-receiving part 21, the locking fastener 50 and the lock hole 11 are coaxially arranged with each other. When the locking fastener 50 moves to the correct locking position, the locking fastener 50 can reliably press against the center of the pressure-receiving part 21 to provide a better force transmission effect and ensure that the linkage 20 can smoothly trigger the sensor 30.

[0079] For example Figure 3 and Figure 4 As shown, in this embodiment, the bottom wall 182 of the limiting seat 18 is also provided with two limiting posts 184. One end of the two reset members 40 is respectively sleeved on the two limiting posts 184, so that the reset members 40 can be limited and avoid displacement during the force-moving process.

[0080] like Figure 1 and Figure 2 As shown, the prompting module 60 is connected to the sensor 30. For example, the prompting module 60 can be electrically connected to the sensor 30 via a line, and the prompting module 60 receives and issues a prompt message based on the correct locking signal. That is, when the locking device 50 moves to the correct locking position (e.g., ... Figure 4 As shown, sensor 30 will only generate a correct locking signal when triggered by linkage 20, causing prompting module 60 to issue a prompt message. Conversely, if sensor 30 is not triggered by linkage 20, it means that locking device 50 has not been correctly locked in place, and prompting module 60 will not issue a prompt message. Therefore, the user can clearly know from the prompt message that locking device 50 has been correctly locked in place, thus preventing the camera device 1 from vibrating or shaking during use due to insecure installation of locking device 50, and ensuring that the camera device 1 can function normally.

[0081] like Figure 1 and Figure 2 As shown, the aforementioned prompting module 60 may include a display unit 61, a sound output unit 62, an indicator light unit 63, a wireless communication unit 64, or a combination of at least two of these. For example, the display unit 61 may be a liquid crystal display (LCD). When the sensor 30 is triggered and generates a correct locking signal, the display unit 61 may display an image or text prompt message to remind the user that the locking device 50 has been correctly locked. The sound output unit 62 may be a speaker or a buzzer. When the sensor 30 is triggered and generates a correct locking signal, the sound output unit 62 may emit an audible prompt message to remind the user. The indicator light unit 63 may be an LED or an incandescent bulb. When the sensor 30 is triggered and generates a correct locking signal, the indicator light unit 63 may emit a bright light prompt message to remind the user. The wireless communication unit 64 can be a Wi-Fi unit, a Bluetooth unit, or a ZigBee unit. When the sensor 30 is triggered and generates a correct latching signal, the wireless communication unit 64 can wirelessly send a prompt message in the form of sound, text, or image to the user device to remind the user. For example, the user device can be the user's mobile phone, computer, or vehicle display.

[0082] In some embodiments, when the sensor 30 is not triggered and does not receive a correct locking signal from the sensor 30, the prompting module 60 may issue a different prompting message than the above-described prompting message to remind the user that the locking device 50 has not been correctly locked. In some embodiments, the other prompting message may be a message in the form of an image, sound, text, or light. For example, when the sensor 30 is triggered and generates a correct locking signal, the indicator light unit 63 may emit a green light (prompt message); when the sensor 30 is not triggered and does not generate a correct locking signal, the indicator light unit 63 may emit a red light (another prompting message).

[0083] Figure 5 This is a cross-sectional view of a second embodiment of the camera device of the present invention. Figure 5 As shown, this embodiment is similar to the one described above. Figures 1 to 4 The difference in the first embodiment is that each reset member 40a in this embodiment is made of elastic rubber or elastic foam, and each reset member 40a abuts between the circuit board 16 and the linkage 20. In this embodiment, each reset member 40a is disposed in the guide groove 183 of the limiting seat 18 on the circuit board 16, and each reset member 40a abuts between the bottom wall 182 of the limiting seat 18 and the linkage 20, but this is not a limitation.

[0084] Figure 6 This is a cross-sectional view of a third embodiment of the camera device of the present invention, as shown below. Figure 6 As shown, this embodiment is similar to the one described above. Figures 1 to 4 The difference from the first embodiment is that each reset member 40b in this embodiment is a magnetic component and includes a first magnetic member 41 and a second magnetic member 42. The first magnetic member 41 and the second magnetic member 42 correspond to each other and maintain a distance. The first magnetic member 41 is disposed on the circuit board 16, and the second magnetic member 42 is disposed on the linkage member 20. The magnetic poles of the first magnetic member 41 and the second magnetic member 42 repel each other. In this way, the magnetic repulsion between the first magnetic member 41 and the second magnetic member 42 can drive the linkage member 20 to be located in the first position. When the linkage member 20 is subjected to force and moves towards the circuit board 16, the first magnetic member 41 and the second magnetic member 42 approach each other and gradually increase the magnetic repulsion. Therefore, when the linkage member 20 is released, it can return to the first position through the magnetic repulsion.

[0085] For example Figure 6As shown, in this embodiment, the first magnetic element 41 of each reset component 40b is disposed within the guide groove 183 of the limiting seat 18 on the circuit board 16, and the first magnetic element 41 is fixed to the bottom wall 182 of the limiting seat 18. Thus, this embodiment of the invention, through a modular design where the first magnetic element 41 is disposed on the limiting seat 18 and the second magnetic element 42 is disposed on the linkage 20, allows the reset components 40b to be easily disassembled or replaced, and avoids direct contact between each reset component 40b and the circuit board 16, achieving an insulation effect.

[0086] Figure 7 This is an exploded perspective view of the fourth embodiment of the camera device of the present invention. Figure 8 This is a cross-sectional view of the fourth embodiment of the camera device of the present invention. Figure 9 This is a cross-sectional view of the fourth embodiment of the camera device of the present invention in the correct locking position. Figures 7 to 9 As shown, this embodiment is similar to the one described above. Figures 1 to 4 The difference from the first embodiment is that the linkage 20a in this embodiment includes a pressure-receiving part 21a, a pivot part 22a, and a trigger part 25a. The pivot part 22a can be a pivot or a shaft hole and is pivotally mounted in the receiving chamber 15, so that the linkage 20a can swing relative to the housing 10 about the pivot part 22a as an axis. In addition, in this embodiment, the linkage 20a is an elongated rod, the pivot part 22a is located at one end of the linkage 20a, the trigger part 25a is a partial area of ​​the other end of the linkage 20a, and the pressure-receiving part 21a is located between the pivot part 22a and the trigger part 25a, wherein the pressure-receiving part 21a is a protrusion and extends into the lock hole 11.

[0087] like Figures 7 to 9 As shown, in this embodiment, the reset member 40c is a spring and abuts against the end of the linkage 20a away from the pivot portion 22a. The linkage 20a can be positioned in a first position based on the abutment of the reset member 40c (e.g., Figure 8 (As shown in the figure), when the linkage 20a is in the first position, the side of the linkage 20a near the lock hole 11 abuts against the housing 10 to achieve positioning. The sensor 30a is disposed on the circuit board 16 and corresponds to the trigger part 25a, and when the linkage 20a is in the first position, the trigger part 25a does not trigger the sensor 30a.

[0088] like Figure 9 As shown, during assembly, the locking member 50 can be rotated and moved relative to the lock hole 11 towards the housing 10 (as indicated by arrow L2) to the correct locking position. The correct locking position refers to the position where the locking member 50, the bracket 70, and the housing 10 are firmly secured to each other without any wobbling. When the locking member 50 is in the correct locking position, it presses against the pressure portion 21a of the linkage 20a, causing the linkage 20a to rotate about the pivot portion 22a from the first position (as indicated by arrow L3) to the second position (as indicated by arrow L3). Figure 9 (as shown in the position). When the linkage 20a is in the second position, the triggering part 25a can trigger the sensor 30a to generate the correct locking signal.

[0089] like Figures 7 to 9 As shown, in this embodiment, the sensor 30a is a non-contact optical sensor and includes a light emitting unit 31 and a light receiving unit 32, which are respectively disposed on opposite sides of the trigger portion 25a. Furthermore, when the linkage 20a is in the aforementioned first position (e.g....), Figure 8 (As shown in the image) When the triggering part 25a is not located between the light emitting unit 31 and the light receiving unit 32, the light emitted by the light emitting unit 31 can be incident on the light receiving unit 32, thereby preventing the sensor 30a from being triggered by the triggering part 25a. When the linkage 20a is in the second position described above (e.g.) Figure 9 (As shown in the figure), the triggering part 25a is blocked between the light emitting unit 31 and the light receiving unit 32, so that the light emitted by the light emitting unit 31 does not enter the light receiving unit 32 and triggers the sensor 30a to generate the correct locking signal.

[0090] In some embodiments, the reset member 40c may also be elastic rubber or elastic foam (e.g., the one described above). Figure 5 The reset element 40a) or magnetic component (e.g., the one described above) Figure 6 Reset component 40b).

[0091] Figure 10 This is a cross-sectional view of the fifth embodiment of the camera device of the present invention. Figure 10 As shown, this embodiment is similar to the one described above. Figures 7 to 9 The difference in the fourth embodiment is that the sensor 30b in this embodiment is a non-contact sensor and includes a first sensing element 33 and a second sensing element 34. The first sensing element 33 is fixed to the trigger portion 25a of the linkage 20a, and the second sensing element 34 is fixed inside the accommodating chamber 15 and maintains a distance from the first sensing element 33. Here, the second sensing element 34 is disposed on the circuit board 16, but the second sensing element 34 can also be disposed in other positions within the accommodating chamber 15. Furthermore, one of the first sensing element 33 and the second sensing element 34 is a Hall sensor, and the other of the first sensing element 33 and the second sensing element 34 is a magnetic material. Therefore, when the linkage 20a is in the aforementioned first position (e.g., ...), Figure 8 (as shown in the image) the first sensor 33 and the second sensor 34 maintain a distance from each other so that the sensor 30b is not triggered. When the linkage 20a is in the second position described above (e.g. Figure 9 (As shown in the figure), the first sensor 33 and the second sensor 34 approach each other and generate a change in magnetic field, so as to trigger the sensor 30b to generate the correct locking signal based on the change in magnetic field.

[0092] In some embodiments, the sensors used in the above embodiments may be contact sensors (e.g., those described above). Figures 2 to 4 Sensor 30) or non-contact sensor (e.g., the one mentioned above) Figures 7 to 9 Sensor 30a or Figure 10 (30b) Sensor, which is not limited to.

[0093] In summary, according to the camera device of the present invention, when the locking fastener moves to the correct locking position, the sensor can be triggered by the linkage to generate a correct locking signal, which in turn causes the prompting module to issue a prompt message. Therefore, the user can clearly know from the prompt message that the locking fastener has been correctly locked in place, thus avoiding the situation where the camera device vibrates or shakes during use due to insecure installation of the locking fastener, and enabling the camera device to function normally.

[0094] Although the technical content of the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any modifications and refinements made by those skilled in the art without departing from the spirit of the present invention should be included within the scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope defined in the appended claims.
