Description

Technical Field

[0001] This utility model relates to the field of housing assembly technology, and in particular to a housing assembly and a smart recorder. Background Technology

[0002] Currently, many devices have internal components exposed during use and need to be covered when not in use. Therefore, sliding covers are often designed into the device's housing to protect these internal components. In some specialized devices, using sliding covers to cover internal components can also provide privacy protection for users. For example, with the rapid development of artificial intelligence, the Internet of Things, and image processing technologies, smart recorders (such as smart home cameras, dashcams, and meeting recording analyzers) are widely used in daily life and work. These devices typically have internal camera modules for collecting image and video information. However, the continuous operation of these camera modules has raised serious concerns about user privacy. For instance, in private places like homes, users desire a reliable and intuitive way to physically cover the camera when not in use, one that is comfortable and convenient to use, to prevent accidental or malicious spying.

[0003] In existing technologies, there are three types of structures for controlling the opening and closing of the sliding cover on the housing assembly: the first is a flip / rotate structure, which opens and closes the cover manually by flipping or rotating it, but the pivot part of this structure is prone to loosening or breakage after long-term use; the second is an electronic shutter structure, which controls the movement of the cover through software, but this structure is complex and costly; the third is a simple push-pull sliding cover, which uses a direct push-pull design, but this design lacks a self-resetting function and cannot automatically position or reset after sliding to a certain position, resulting in unclear tactile feedback and a poor user experience. In summary, existing technologies have poor smoothness, stability, tactile feedback, and user experience when controlling the opening and closing of the sliding cover on the housing assembly. Utility Model Content

[0004] This utility model provides a housing assembly and an intelligent recorder to solve the problems of poor smoothness, stability, operation feel and user experience in the prior art when controlling the sliding cover opening and closing of the housing assembly.

[0005] A housing assembly includes a housing, a sliding cover, and two elastic elements;

[0006] The housing is provided with a movable groove arranged along a first direction, and a working window for exposing internal components is provided at one end of the movable groove. The sliding cover is movably installed in the movable groove along the first direction.

[0007] The first end of each elastic element is connected to the inner bottom wall of the movable groove, and the second end of each elastic element is connected to the sliding cover. The connection points of the two elastic elements and the sliding cover are spaced apart along the second direction.

[0008] Under the elastic force of the two elastic elements, the sliding cover is positioned to cover or not cover the working window;

[0009] Under the action of external force, the sliding cover moves along the first direction to a position that either does not cover or covers the working window.

[0010] Preferably, the housing is provided with a locking structure; when the sliding cover is moved to a position that does not cover or covers the working window under the action of external force, the locking structure locks the sliding cover.

[0011] Preferably, the two elastic elements are symmetrically arranged based on the centerline of the working window in the first direction.

[0012] Preferably, the first ends of the two elastic elements are concentrically arranged.

[0013] Preferably, each of the elastic elements includes a helical portion, two connecting arms extending from both ends of the helical portion, and a spring fulcrum disposed at the end of each connecting arm; the included angle between the two connecting arms is an obtuse angle;

[0014] One of the spring fulcrums is connected to the inner bottom wall of the movable groove, and the other spring fulcrum is connected to the sliding cover.

[0015] Preferably, the inner bottom wall of the movable groove is provided with two fixed columns and two first support columns, and the sliding cover is provided with two second support columns;

[0016] In each of the elastic elements, the spiral portion is fitted onto a fixed post, one spring fulcrum is fitted onto a first support post, and the other spring fulcrum is fitted onto a second support post;

[0017] Alternatively, the inner bottom wall of the movable groove is provided with two fixed columns and one first support column, and the sliding cover is provided with two second support columns;

[0026] The camera module is disposed inside the housing and is positioned corresponding to the working window.

[0027] The housing assembly provided in this embodiment of the utility model achieves the reset of the sliding cover by setting two elastic elements. The two elastic elements can provide a stable and balanced rebound force, making the opening and closing of the sliding cover smoother, providing a clear tactile feel, and giving the product a high-end user experience. When the user pushes the sliding cover from the initial position to the position where it covers or does not cover the working window (i.e., the final position of opening or closing), the elastic elements are compressed and store energy. When the user releases their hand, the elastic elements release energy and can automatically push the sliding cover back to the initial position, realizing a one-button automatic reset function. The operation is very convenient and realizes a user-friendly human-computer interaction. The compression and release process of the elastic elements, through precise mechanical design, provides the user with a clear "step feel" and "resistance change feel". The sliding cover needs to overcome a certain initial force when it starts to move. The force feels stable during the movement, and there is a clear confirmation of the end position when it reaches the end, which greatly improves the operating feel and user experience.

[0037] This utility model embodiment provides a housing assembly, referring to... Figure 1 , Figure 2 and Figure 3The device includes a housing 1, a sliding cover 2, and two elastic elements 3. The housing 1 has a movable groove 11 arranged along a first direction. One end of the movable groove 11 has a working window for exposing internal components. The sliding cover 2 is movably installed in the movable groove 11 along the first direction. The first end of each elastic element 3 is connected to the inner bottom wall of the movable groove 11, and the second end of each elastic element 3 is connected to the sliding cover 2. The connection points between the two elastic elements 3 and the sliding cover 2 are spaced apart along a second direction. Under the elastic force of the two elastic elements 3, the sliding cover 2 is positioned to cover or not cover the working window. Under the action of an external force, the sliding cover 2 is moved along the first direction to a position that does not cover or covers the working window.

[0038] The first direction and the second direction are two mutually perpendicular directions. For example, the first direction is the length direction of the shell 1, and the second direction is the width direction of the shell 1.

[0039] As an example, the housing assembly includes a housing 1, a sliding cover 2, and two elastic elements 3. The housing 1 has a movable groove 11 arranged along a first direction, and a working window is provided at one end of the movable groove 11, through which internal components, such as a camera module 6, are exposed, allowing the camera module 6 to collect image and video information. During installation, the sliding cover 2 is movably installed in the movable groove 11 along the first direction. The first end of each elastic element 3 is connected to the inner bottom wall of the movable groove 11, and the second end of each elastic element 3 is connected to the sliding cover 2. The connection points between the two elastic elements 3 and the sliding cover 2 are spaced apart along a second direction. This arrangement allows for two operational scenarios: First, under the elastic force of the two elastic elements 3, the sliding cover 2 is positioned to cover the working window, thus protecting the internal components. Second, under external force, i.e., when the user pushes the sliding cover 2 along the first direction to a position where it does not cover the working window, the internal components are exposed through the working window for operation. The second method involves using the elastic force of the two elastic elements 3 to keep the sliding cover 2 in a position where it does not cover the working window. In this position, the internal components are exposed through the working window for operation. Under external force, i.e., when the user pushes the sliding cover 2 along the first direction to a position that covers the working window, the internal components are protected. This example features a simple housing assembly structure, easy assembly, high durability, and long service life. The two elastic elements 3 optimize the operating feel of the sliding cover 2. The sliding cover 2 provides physical shielding, effectively protecting the internal components and offering users a smooth, tactile, and reliable operating experience.

[0040] In this example, two elastic elements 3 are used to reset the sliding cover 2. These two elastic elements 3 provide a stable and balanced rebound force, making the opening and closing of the sliding cover 2 smoother, providing a clear tactile feel, and giving the product a high-end user experience. When the user pushes the sliding cover 2 from its initial position to a position that covers or uncovers the working window (i.e., the final position of opening or closing), the elastic elements 3 are compressed and store energy. When the user releases their hand, the elastic elements 3 release the energy, automatically pushing the sliding cover 2 back to its initial position, achieving a one-button automatic reset function. This is very convenient and provides a user-friendly human-computer interaction. The compression and release process of the elastic elements 3, through precise mechanical design, provides the user with a clear sense of "stepping" and "resistance change." The sliding cover 2 needs to overcome a certain initial force when it starts to move, the force is stable during the movement, and there is a clear confirmation of its position when it reaches the end point, greatly improving the operating feel and user experience.

[0041] In one embodiment, the housing 1 is provided with a locking structure; when the sliding cover 2 is moved to a position that does not cover or covers the working window under the action of external force, the locking structure locks the sliding cover 2.

[0042] As an example, the housing 1 is equipped with a locking structure. When the sliding cover 2 is moved to a position that does not cover or covers the working window under the action of external force, the locking structure locks the sliding cover 2, thus keeping the sliding cover 2 in the position that does not cover or covers the working window, so as to expose or cover and protect the internal components. When it is necessary to cover or not cover the internal components, the external force is removed, the locking structure is unlocked, and the sliding cover 2 returns to its original position under the elastic force of the two elastic elements 3. For example, the locking structure is a latch or a magnet. The sliding cover 2 is provided with a locking groove or magnetic metal. The latch engages with the locking groove, and the magnet engages with the magnetic metal to lock the sliding cover 2.

[0043] In one embodiment, reference is made to Figure 2 The two elastic elements 3 are symmetrically arranged based on the centerline of the working window in the first direction.

[0044] As an example, the two elastic elements 3 are symmetrically arranged based on the centerline of the working window in the first direction. This symmetrical arrangement allows the two elastic elements 3 to evenly distribute the load from the sliding cover 2 and the surrounding structure during operation, avoiding premature fatigue or damage to one elastic element 3 due to uneven force distribution. This uniform force distribution helps improve the stability and reliability of the entire structure and extends the service life of the equipment. The symmetrical arrangement of the elastic elements 3 can form a mutually restraining balance mechanism. When the sliding cover 2 attempts to shift to one side, the elastic elements 3 on both sides generate elastic forces in opposite directions, preventing the shift from occurring and thus maintaining the stability of the sliding cover 2 in the center position in the first direction, ensuring the normal operating accuracy of the equipment. The symmetrical layout allows the two elastic elements 3 to work synergistically during operation. When the sliding cover 2 is displaced by external forces, the two elastic elements 3 simultaneously undergo elastic deformation, jointly providing a restoring force. This synergistic effect can improve the speed and efficiency of elastic response, allowing the sliding cover 2 to return to its initial position more quickly and reducing errors and instabilities caused by delayed elastic response.

[0045] In one embodiment, reference is made to Figure 2 The first ends of the two elastic elements 3 are set concentrically.

[0046] As an example, two elastic elements 3 form the entire elastic assembly. The first ends of the two elastic elements 3 are concentrically arranged, which enhances the symmetry of the entire structure and makes the force on the structure more balanced in all directions. When subjected to external force, the force transmission path is more direct and uniform. The concentric structure helps to improve the torsional resistance of the entire elastic assembly. When the sliding cover 2 is moved under force, the two elastic elements 3 will simultaneously produce elastic deformation in opposite directions to resist torsion. Because the first ends are concentric, they can work together better to form a stable anti-torsion mechanism, effectively preventing the entire elastic assembly from being damaged by excessive torsion, and improving the reliability and service life of the entire elastic assembly. The concentric arrangement can make the two elastic elements 3 have a more consistent elastic response when deformed under force. Under the same stress conditions, their deformation and recovery force will be closer, thereby providing more stable and predictable elastic support for the connected structure.

[0047] In one embodiment, reference is made to Figure 2 and Figure 4 Each elastic element 3 includes a spiral portion 31, two connecting arms 32 extending from both ends of the spiral portion 31, and a spring fulcrum 33 disposed at the end of each connecting arm 32; the included angle between the two connecting arms 32 is an obtuse angle; one spring fulcrum 33 is connected to the inner bottom wall of the movable groove 11, and the other spring fulcrum 33 is connected to the sliding cover 2.

[0048] As an example, each elastic element 3 includes a spiral portion 31, two connecting arms 32, and two spring fulcrums 33. The spiral portion 31 is an energy storage deformation mechanism with at least two spiral turns. The two connecting arms 32 are components extending from both ends of the spiral portion 31. The two spring fulcrums 33 are respectively disposed at the ends of the two connecting arms 32. The spring fulcrums 33 can be configured as hooks. The included angle between the two connecting arms 32 is an obtuse angle. During installation, one spring fulcrum 33 is connected to the inner bottom wall of the movable groove 11, and the other spring fulcrum 33 is connected to the sliding cover 2. With this configuration, in the initial state, the elastic element 3 keeps the sliding cover 2 in the initial position. When the user applies an external force to move the sliding cover 2, the corresponding connecting arm 32 is rotated around the spiral portion 31 by the corresponding spring fulcrum 33 to generate a rebound force. When the user removes the external force, the sliding cover 2 automatically resets under the action of the rebound force. The sliding cover 2 is reset via two elastic elements 3. These two elastic elements 3 provide a stable and balanced rebound force, making the opening and closing of the sliding cover 2 smoother and providing a clear tactile feel, giving the product a high-end user experience. When the user pushes the sliding cover 2 from its initial position to a position that covers or does not cover the working window (i.e., the final position of opening or closing), the elastic elements 3 are compressed and store energy. When the user releases their hand, the elastic elements 3 release the energy, automatically pushing the sliding cover 2 back to its initial position, realizing a one-button automatic reset function. The operation is very convenient, achieving a user-friendly human-computer interaction.

[0049] In one embodiment, reference is made to Figure 2 and Figure 3 The inner bottom wall of the movable groove 11 is provided with two fixed posts 12 and two first support posts 13, and the sliding cover 2 is provided with two second support posts 21; in each elastic element 3, the spiral part 31 is fitted on a fixed post 12, a spring fulcrum 33 is fitted on a first support post 13, and another spring fulcrum 33 is fitted on a second support post 21; or, the inner bottom wall of the movable groove 11 is provided with two fixed posts 12 and one first support post 13, and the sliding cover 2 is provided with two second support posts 21; the spiral parts 31 of the two elastic elements 3 are respectively fitted on the two fixed posts 12, one spring fulcrum 33 of the two elastic elements 3 is fitted on the same first support post 13, and the other spring fulcrum 33 of the two elastic elements 3 are respectively fitted on the two second support posts 21.

[0050] As an example, two layout options are presented:

[0051] In the first configuration, two fixed posts 12 and two first support posts 13 are provided on the inner bottom wall of the movable groove 11, and two second support posts 21 are provided on the sliding cover 2. The two fixed posts 12 are symmetrically arranged based on the center line of the working window in the first direction, the two first support posts 13 are symmetrically arranged based on the center line of the working window in the first direction, and the two second support posts 21 are symmetrically arranged based on the center line of the working window in the first direction. During installation, in each elastic element 3, the spiral part 31 is fitted onto one fixed post 12, one spring fulcrum 33 is fitted onto one first support post 13, and the other spring fulcrum 33 is fitted onto one second support post 21. The two elastic elements 3 are symmetrically arranged based on the center line of the working window in the first direction. This symmetrical arrangement allows the two elastic elements 3 to work synergistically. When the sliding cover 2 is displaced by an external force, the two elastic elements 3 undergo elastic deformation simultaneously, jointly providing a restoring force. This synergistic effect can improve the speed and efficiency of elastic response, enabling the sliding cover 2 to return to its initial position more quickly and reducing errors and instabilities caused by delayed elastic response.

[0052] The second configuration involves two fixed posts 12 and one first support post 13 on the inner bottom wall of the movable groove 11, and two second support posts 21 on the sliding cover 2. The two fixed posts 12 are symmetrically arranged based on the center line of the working window in the first direction, and the two second support posts 21 are symmetrically arranged based on the center line of the working window in the first direction. During installation, the spiral parts 31 of the two elastic elements 3 are respectively fitted onto the two fixed posts 12, one spring fulcrum 33 of the two elastic elements 3 is fitted onto the same first support post 13, and the other spring fulcrum 33 of the two elastic elements 3 is respectively fitted onto the two second support posts 21. With this arrangement, the two elastic elements 3 form the entire elastic assembly, and the first ends of the two elastic elements 3 are concentrically arranged, which enhances the symmetry of the entire structure, makes the force on the structure more balanced in all directions, and makes the force transmission path more direct and uniform when subjected to external force.

[0053] In one embodiment, reference is made to Figure 2 and Figure 3 The housing assembly also includes a guide rail 4, which is disposed in the housing 1 and located in the movable groove 11; the sliding cover 2 is movably mounted on the guide rail 4, and the first end of each elastic member 3 is disposed on the guide rail 4.

[0054] As an example, the housing assembly also includes a guide rail 4, which is placed on the housing 1 and located in the movable groove 11 during installation; the sliding cover 2 is movably mounted on the guide rail 4, and the first end of each elastic element 3 is disposed on the guide rail 4; in this configuration, the guide rail 4 provides guidance and limit for the movement of the sliding cover 2, and avoids the sliding cover 2 from being offset or misaligned.

[0055] In one embodiment, reference is made to Figure 2 and Figure 3The housing assembly also includes two slide rails 5; the two slide rails 5 are spaced apart on the slide cover 2 along the second direction and are movably mounted on the guide rail 4 along the first direction; the second end of each elastic member 3 is mounted on a slide rail 5.

[0056] As an example, the housing assembly also includes two slide rails 5; during installation, the two slide rails 5 are spaced apart on the sliding cover 2 along the second direction and movably mounted on the guide rail 4 along the first direction; the second end of each elastic element 3 is mounted on a slide rail 5; with this arrangement, the two slide rails 5 are symmetrically arranged based on the center line of the working window in the first direction, ensuring smooth movement of the sliding cover 2. The two slide rails 5 cooperate with the guide rail 4 to make the movement of the sliding cover 2 smoother, without jamming or shaking, and the overall structure is very robust and reliable.

[0057] In one embodiment, reference is made to Figure 2 and Figure 3 The guide rail 4 is a plastic guide rail, and the slide rail 5 is a metal slide rail.

[0058] As an example, guide rail 4 is a plastic guide rail, and slide rail 5 is a metal slide rail. This arrangement utilizes the low coefficient of friction and good wear resistance between metal and plastic to achieve smooth, low-wear, and long-life relative sliding. The use of metal parts enhances the strength and durability of the mechanism, avoiding the disadvantages of pure plastic structures being prone to wear and deformation.

[0059] This utility model provides an intelligent recorder, as shown in the following embodiment. Figure 1 , Figure 2 and Figure 3 It includes a camera module 6 and a housing assembly; the camera module 6 is located inside the housing 1 and is positioned corresponding to the working window.

[0060] As an example, the smart recorder includes a camera module 6 and a housing assembly. The housing assembly includes a housing 1, a sliding cover 2, and two elastic members 3. The housing 1 has a movable groove 11 arranged along a first direction, and a working window is provided at one end of the movable groove 11. During installation, the camera module 6 is placed inside the housing 1, corresponding to the working window. The camera module 6 is exposed through the working window, and image and video information is acquired through the camera module 6. The sliding cover 2 is movably installed in the movable groove 11 along the first direction. The first end of each elastic member 3 is connected to the inner bottom wall of the movable groove 11, and the second end of each elastic member 3 is connected to the sliding cover 2. The connection points between the two elastic members 3 and the sliding cover 2 are spaced apart along a second direction. This arrangement allows for two operating scenarios: First, under the elastic force of the two elastic members 3, the sliding cover 2 is positioned to cover the working window, thus protecting the camera module 6. Second, under external force, i.e., when the user pushes the sliding cover 2 along the first direction to a position where it does not cover the working window, the camera module 6 is exposed through the working window for operation. The second method involves using the elastic force of the two elastic elements 3 to position the sliding cover 2 in a position that does not cover the working window. In this position, the camera module 6 is exposed through the working window for operation. Under external force, i.e., when the user pushes the sliding cover 2 along the first direction to a position that covers the working window, the camera module 6 is thus protected. This example features a simple housing assembly structure, easy assembly, high durability, and long lifespan. The two elastic elements 3 optimize the operating feel of the sliding cover 2. Physical shielding via the sliding cover 2 effectively protects the camera module 6 and provides users with a smooth, tactile, and reliable operating experience. Physical shielding via the sliding cover 2 effectively protects the camera module 6, fundamentally eliminating the risk of privacy leaks.
