Description

Technical Field

[0001] This utility model relates to a lens device and a housing device. Background Technology

[0002] With the development of communication technology, the demand for image acquisition is increasing. As a result, various lens devices or electronic products with lens devices have appeared on the market. Examples include webcams, dashcams, tablets, laptops, and all-in-one PCs.

[0003] As users of electronic products become increasingly concerned about cybersecurity and privacy, lens devices with shutters have emerged on the market. These shutters are positioned next to the lens and can be moved to the lens to block its field of view, thus preventing unauthorized filming due to hacking. Generally, users must manually move the shutter to the lens. However, this manual method is inconvenient, and the shutter often ends up only partially moving, failing to completely block the lens's view, thus requiring improvement. Utility Model Content

[0004] In view of the above-mentioned problems, the main objective of this utility model is to provide a lens device and housing device, which solves the problems of inconvenient operation and incomplete shielding caused by the need for manual control of known shielding structures through the structural and connection relationship between the transmission module and the (first and second) shielding members.

[0044] To better understand the technical content of this utility model, preferred embodiments are described below.

[0045] Figure 1 This is a schematic diagram of a lens device according to an embodiment of the present invention. Figure 2 for Figure 1 A partially exploded diagram of the lens assembly shown. Figure 3 for Figure 2 The diagram shown is an exploded view of part of the lens assembly. Figure 4 for Figure 3 Please refer to the front view of the assembled lens assembly shown below. Figure 1 , Figure 2 , Figure 3 and Figure 4As shown. First, the lens device 1 in this embodiment is an example of a webcam. In other embodiments, the lens device 1 can also be an electronic product such as a dashcam, tablet computer, laptop computer, or all-in-one PC. In this embodiment, the lens device 1 includes a housing 10, a lens module 20, a first shielding member 31, a second shielding member 32, and a transmission module 40. The housing 10 includes an opening 11. The lens module 20 is disposed within the housing 10 and corresponds to the opening 11. In this embodiment, the housing 10 may include a front housing 12 and a rear cover 13, such as... Figure 2 As shown. Opening 11 is located in the front housing 12, while the lens module 20 can be located in the rear cover 13. When the lens module 20, together with the rear cover 13, is assembled to the front housing 12, the lens module 20 is located inside the housing 10 and corresponds to opening 11. It should be noted that... Figure 3 and Figure 4 The lens assembly 1 shown includes a front housing 12, a first shielding member 31, a second shielding member 32, and a transmission module 40.

[0046] The first shielding member 31 and the second shielding member 32 are movably disposed on the front housing 12 of the housing 10 to shield or expose the opening 11. Therefore, the first shielding member 31 and the second shielding member 32 are adjacent to the opening 11. Preferably, the first shielding member 31 and the second shielding member 32 are respectively disposed on opposite sides of the opening 11. In this embodiment, the first shielding member 31 and the second shielding member 32 are disposed on the left and right sides of the opening 11. In other embodiments, the first shielding member 31 and the second shielding member 32 may also be disposed on the upper and lower sides of the opening 11, or on opposite diagonals of the opening 11, and this utility model is not limited thereto. Furthermore, in this embodiment, the first shielding member 31 and the second shielding member 32 can be moved in the front housing 12 by the transmission module 40, thereby shielding or exposing the opening 11.

[0047] In this embodiment, the transmission module 40 is disposed on the front housing 12 of the housing 10, such as... Figure 3 As shown. The transmission module 40 includes a drive unit 41, at least one transmission gear 42, a first transmission member 43, and a second transmission member 44. Preferably, in this embodiment, the drive unit 41 includes a drive gear 411 and a motor 412 (shown in dashed lines). The drive gear 411 is connected to the motor 412, and the motor 412 can cause the drive gear 411 to rotate clockwise or counterclockwise. In this embodiment, the transmission gear 42 is disposed on the front housing 12 of the housing 10, preferably adjacent to the opening 11, but this invention is not limited thereto. In this embodiment, the number of transmission gears 42 is two. Preferably, the two transmission gears 42 are located on the upper and lower sides of the opening 11, respectively. In other embodiments, the transmission module 40 may also have only one transmission gear 42, which can achieve the same function.

[0048] In this embodiment, the first transmission member 43 and the second transmission member 44 are disposed adjacent to the opening 11. The first transmission member 43 is connected to the first shielding member 31, the drive unit 41, and the transmission gear 42, while the second transmission member 44 is connected to the second shielding member 32 and the transmission gear 42. Preferably, the first transmission member 43 in this embodiment further includes a first rack 431 and at least one second rack 432. The first rack 431 meshes with the drive gear 411, and the second rack 432 meshes with the transmission gear 42. Therefore, the positions of the first rack 431 and the second rack 432 correspond to the drive gear 411 and the transmission gear 42, respectively, and the number of second racks 432 is the same as the number of transmission gears 42. In this embodiment, the drive unit 41 is disposed away from the opening 11, and through the meshing of the first rack 431 with the drive gear 411, the drive unit 41 can drive the entire first transmission member 43 (including the first rack 431 and the second rack 432) to move. In other embodiments, the drive unit 41 may also be located in other areas depending on the spatial configuration of different models of the lens device 1. For example, the drive unit 41 may also be located near the opening 11, so that the drive unit 41 can directly output power to the first transmission member 43 to drive the first transmission member 43 to move.

[0049] Preferably, the first transmission member 43 further includes a first connecting member 433, which is also elongated. In this embodiment, the drive gear 411 and the transmission gear 42 are located on opposite sides of the first connecting member 433. Figure 4 For example, the drive gear 411 is located at the lower right of the first connector 433, while the two transmission gears 42 are located at the upper left and lower left of the first connector 433, respectively. Correspondingly, the first rack 431 is connected to the right side and lower end of the first connector 433 to mesh with the drive gear 411. The first transmission member 43 includes two second racks 432, which are connected to the upper left and lower left ends of the first connector 433, respectively, to mesh with the two transmission gears 42. In other words, in this embodiment, the two second racks 432 are connected to opposite ends of the first connector 433 and are located on the same side (e.g., the left side), while the first rack 431 and the second rack 432 are located on different sides. In other embodiments, the first rack 431 and the second rack 432 may also be located on the same side of the first connector 433 (e.g., both located on the left side of the first connector 433), and the same transmission function can be achieved simply by adjusting the position and rotation direction of the drive gear 411 and the transmission gear 42.

[0050] In this embodiment, the second transmission member 44 is connected to the transmission gear 42 and can be moved by the transmission gear 42. Preferably, the second transmission member 44 in this embodiment includes at least one third rack 441 and a second connecting member 442. The third rack 441 meshes with the transmission gear 42, so the number of third racks 441 is the same as the number of transmission gears 42. In other words, the second transmission member 44 in this embodiment includes two third racks 441. Similarly, Figure 4 For example, the two transmission gears 42 are located at the upper right and lower right of the second connecting member 442, respectively. Correspondingly, the two third racks 441 are connected to the upper right and lower right ends of the second connecting member 442, respectively, to mesh with the two transmission gears 42. In other words, in this embodiment, the two third racks 441 are connected to the opposite ends of the second connecting member 442 and are located on the same side (e.g., the right side). Furthermore, the two second racks 432 and the two third racks 441 are located on opposite sides of the two transmission gears 42, respectively. Specifically, the upper second rack 432 and the third rack 441 are located on opposite sides of the upper transmission gear 42, while the lower second rack 432 and the third rack 441 are located on opposite sides of the lower transmission gear 42, so that the second racks 432 and the third rack 441 can move relative to each other by simultaneously meshing with the transmission gears 42. It should be noted that the first rack 431 can achieve more efficient power output by having a different gear ratio than the second rack 432 and the third rack 441, thereby overcoming the obstacle of space configuration and allowing the drive unit 41 to be placed in other areas of the housing 10.

[0051] Furthermore, the first transmission member 43 is connected to the first shielding member 31, and the second transmission member 44 is connected to the second shielding member 32, so that the first transmission member 43 and the second transmission member 44 can respectively drive the first shielding member 31 and the second shielding member 32 to move. Figure 5 for Figure 4 The schematic diagram of the partial lens assembly along line AA is shown below. Please refer to it. Figure 3 , Figure 4 and Figure 5 As shown. In this embodiment, the first shielding member 31 and the second shielding member 32 are disposed on the outer side of the front housing 12, while the first transmission member 43 and the second transmission member 44 are disposed on the inner side of the front housing 12. Furthermore, the housing 10 also includes a guide rail 14, which is located on the front housing 12 of the housing 10. The guide rail 14 has an elongated open structure, allowing the first shielding member 31 or the first transmission member 43 to pass through the guide rail 14 and connect to each other, and the second shielding member 32 or the second transmission member 44 to pass through the guide rail 14 and connect to each other. It should be noted that in this embodiment, the first shielding member 31 and the first transmission member 43 are both connected to each other through the guide rail 14, and the second shielding member 32 and the second transmission member 44 are both connected to each other through the guide rail 14. It should also be noted that the front view (e.g., Figure 4And later Figure 7 The guide track 14 in the diagram is marked on the edge line.

[0052] Preferably, in this embodiment, the first shielding member 31 has at least one first locking portion 311, and the second shielding member 32 has at least one second locking portion 321. The first locking portion 311 is a protrusion protruding from the surface of the first shielding member 31, and the second locking portion 321 is a protrusion protruding from the surface of the second shielding member 32. The first locking portion 311 passes through the guide rail 14 and is connected to the first transmission member 43, and the second locking portion 321 passes through the guide rail 14 and is connected to the second transmission member 44. Preferably, in this embodiment, the first transmission member 43 further includes at least one first guide portion 434, and the second transmission member 44 further includes at least one second guide portion 443. The first guide portion 434 is a protrusion protruding from the surface of the first connecting member 433, and the second guide portion 443 is a protrusion protruding from the surface of the second connecting member 442. In this embodiment, the first guide portion 434 and the second guide portion 443 each have an opening, and the inner diameter of the opening is larger than the outer diameter of the first locking portion 311 and the second locking portion 321, respectively. Therefore, the first guide portion 434 can be sleeved on the outside of the first locking portion 311, and the second guide portion 443 can be sleeved on the outside of the second locking portion 321, as shown below. Figure 5 As shown.

[0053] Furthermore, in this embodiment, the first locking part 311 and the first guiding part 434 are interconnected within the guiding rail 14, and the second locking part 321 and the second guiding part 443 are also interconnected within the guiding rail 14. When the first transmission member 43 and the second transmission member 44 move, the first guiding part 434 and the second guiding part 443 move within the guiding rail 14, simultaneously driving the first locking part 311 and the second locking part 321 to move. Figure 5 As shown, preferably, the opposite side walls (e.g., upper and lower side walls) of the first guide portion 434 in this embodiment abut against the two inner walls of the guide track 14, respectively. Similarly, the opposite side walls (e.g., upper and lower side walls) of the second guide portion 443 can also abut against the two inner walls of the guide track 14, respectively. With the aforementioned structure, the first locking portion 311, the second locking portion 321, the first guide portion 434, and the second guide portion 443 can move smoothly within the guide track 14.

[0054] In other embodiments, the first locking part 311 and the second locking part 321 may be respectively sleeved on the outer sides of the first guide part 434 and the second guide part 443. Alternatively, only the first locking part 311 and the second locking part 321 may pass through the guide rail 14 to connect to the first transmission member 43 and the second transmission member 44, respectively. Alternatively, only the first guide part 434 and the second guide part 443 may pass through the guide rail 14 to connect to the first shielding member 31 and the second shielding member 32, respectively. All of the aforementioned connection methods allow the first transmission member 43 and the second transmission member 44 to drive the first shielding member 31 and the second shielding member 32, respectively; therefore, this invention is not limited in this regard. In other embodiments, the first shielding member 31 and the second shielding member 32 may be disposed on the inner side of the front housing 12, allowing the first transmission member 43 and the second transmission member 44 to be directly connected to the first shielding member 31 and the second shielding member 32, respectively; this invention is also not limited in this regard.

[0055] In this embodiment, the housing 10 has four guide rails 14, two of which are located on the left side of the opening 11, and the other two are located on the right side of the opening 11, at the upper and lower ends respectively. In this embodiment, the number of the first locking part 311, the second locking part 321, the first guide part 434, and the second guide part 443 are each two, and they are interconnected within the four guide rails 14. In other embodiments, the housing 10 may have only one guide rail 14, which may be arranged horizontally at the upper and / or lower end of the opening 11, and the number of the first locking part 311, the second locking part 321, the first guide part 434, and the second guide part 443 may each be one; this invention is not limited in this respect. Preferably, the transmission module 40 in this embodiment further includes four locking fasteners 45. The locking fastener 45 can be, for example, but not limited to, screws, locked into the ends of the two first guide portions 434 and the two second guide portions 443 respectively, to fix the connection between the first shielding member 31 and the first transmission member 43, and to fix the connection between the second shielding member 32 and the second transmission member 44. In other embodiments, it can also be fixed by means of snap-fitting, gluing, or welding, etc., and this utility model is not limited thereto.

[0056] Figure 6 for Figure 4 The diagram shown is a partial view of the lens assembly 1 on the side of the first shielding member 31 and the second shielding member 32. Figure 7 for Figure 4 The diagram shown illustrates how the transmission module moves the first shielding member 31 and the second shielding member 32 to the shielding opening 11. Figure 8 for Figure 6 The schematic diagram shown below illustrates the movement of the first shielding member 31 and the second shielding member 32 to the shielding opening 11. Please refer to the following diagram as well. Figure 4 , Figure 6 , Figure 7 and Figure 8As shown. Through the above structure, the transmission module 40 can drive the first shielding member 31 and the second shielding member 32 to move within the front housing 12, thereby shielding or exposing the opening 11. Specifically, the drive unit 41 of the transmission module 40 can be electrically connected to a physical switch or to the control module of the applied electronic product. When the lens module 20 is turned on or off, the motor 412 of the drive unit 41 starts to operate, driving the drive gear 411 to rotate. Because the first rack 431 meshes with the drive gear 411, the drive gear 411 is driven to rotate while simultaneously moving the first transmission member 43. Because both the second rack 432 and the third rack 441 mesh with the transmission gear 42, the second rack 432, while driving the transmission gear 42 to rotate, further drives the third rack 441, and simultaneously, through the third rack 441, drives the entire second transmission member 44 to move. Furthermore, since the first transmission member 43 and the second transmission member 44 are respectively connected to the first shielding member 31 and the second shielding member 32, when the first transmission member 43 and the second transmission member 44 move, they can respectively drive the first shielding member 31 and the second shielding member 32 to move, thereby shielding or exposing the opening 11.

[0057] In this embodiment, when the lens module 20 is closed, the drive gear 411 can be set to rotate along a first rotation direction; and when the lens module 20 is open, the drive gear 411 can be set to rotate along a second rotation direction. The first rotation direction can be, for example, counterclockwise, and the second rotation direction can be, for example, clockwise. When the drive gear 411 rotates along the first rotation direction (e.g., counterclockwise), the first rack 431 can drive the first transmission member 43 to move towards the opening 11, such as... Figure 4 As indicated by the arrow symbol. Figure 4 For example, the first transmission component 43 moves to the left. At this time, the transmission gear 42 is driven to rotate by the second rack 432. The rotation of the transmission gear 42 then drives the third rack 441 and the second transmission component 44 together to move towards the opening 11. For example, when the second rack 432, located above the transmission gear 42, moves to the left, it can drive the transmission gear 42 to rotate counterclockwise, and drive the third rack 441, located below, to move to the right. Figure 4 As indicated by the arrow symbol. Simultaneously, the first shielding member 31 and the second shielding member 32 are respectively driven by the first transmission member 43 and the second transmission member 44 to move towards the opening 11, thereby shielding the opening 11, as if... Figure 4 and Figures 6 to 7 and Figure 8 .

[0058] Conversely, when the drive gear 411 rotates along the second rotation direction (e.g., clockwise), it also drives the first transmission member 43 to move away from the opening 11 via the first rack 431, such as... Figure 7 As indicated by the arrow symbol. Figure 7 For example, the first transmission member 43 moves to the right. At this time, the transmission gear 42 is driven by the second rack 432 to rotate (e.g., clockwise). The rotation of the transmission gear 42 drives the third rack 441 and the second transmission member 44 to move away from the opening 11, for example, to the left. At the same time, the first shielding member 31 and the second shielding member 32 are driven by the first transmission member 43 and the second transmission member 44 respectively to move away from the opening 11, so as to expose the opening 11, as if from Figure 7 and Figures 8 to 4 and Figure 6 .

[0059] In this embodiment, the guide rail 14, the second rack 432, and the third rack 441 are parallel to the major axis of the opening 11, allowing the first shielding member 31 and the second shielding member 32 to open and close along the major axis of the opening 11. Figure 4 and Figure 7 For example, the first shielding member 31 and the second shielding member 32 can open and close left and right. In other embodiments, the guide rail 14, the second rack 432 and the third rack 441 are parallel to the short axis direction or the diagonal of the opening 11, so that the first shielding member 31 and the second shielding member 32 open and close along the short axis direction or the diagonal of the opening 11, so as to present the action of opening and closing up and down or diagonally.

[0060] In addition, this utility model provides a housing device, which includes a housing, a first shielding member, a second shielding member, and a transmission module. The housing includes an opening. The first shielding member and the second shielding member are movably disposed in the housing and adjacent to the opening.
