[0006] A handle, which is movably disposed at the mounting port; and

[0007] A drive assembly, which may be disposed in the housing and is connected to the handle in a driving manner;

[0008] When the housing is placed on the mounting surface, the handle retracts into the mounting port; when the housing is lifted, the drive assembly is triggered to drive the handle to extend from the mounting port.

[0009] In one embodiment of the housing assembly of this application, the driving assembly includes:

[0010] A linkage structure, comprising a driving link and a follower link hinged at their ends, wherein the driving link is movably configured, and the end of the follower link furthest from the driving link is hinged to the handle; and

[0011] A driving component, wherein the driving component is connected to the active connecting rod.

[0012] The driving component drives the active linkage to move so as to extend or retract the handle from the mounting port.

[0013] In one embodiment of the housing assembly of this application, the mounting port is opened on the top wall of the housing, the bottom wall of the housing is provided with a through hole, and the driving member is disposed opposite to the through hole;

[0014] At least a portion of the drive member can extend and retract from the through hole to drive the active linkage.

[0015] In one embodiment of the housing assembly of this application, the drive member is provided with a counterweight.

[0016] In one embodiment of the housing assembly of this application, the counterweight is disposed at the bottom of the drive member. The counterweight includes a limiting part and a telescopic part connected to each other. The limiting part is located within the housing, and the telescopic part protrudes from the surface of the limiting part facing the through hole and is inserted into the through hole.

[0017] In one embodiment of the housing assembly of this application, the end of the active link away from the follower link is rotatably disposed, and the drive member drives the active link to rotate so that the handle extends or retracts from the mounting port.

[0018] In one embodiment of the housing assembly of this application, the end of the active link away from the follower link is provided with a gear portion, the driving member is provided with a rack, the rack meshes with the gear portion, and the driving member is slidably disposed so as to drive the gear portion to rotate during sliding.

[0019] And / or, the linkage structure further includes a rotating shaft, the rotating shaft being connected to the inner wall of the housing, a limiting groove being formed on the rotating shaft, and the end of the active linkage away from the follower linkage being sleeved on the rotating shaft and limited in the limiting groove;

[0020] And / or, the inner wall of the housing is provided with a sliding groove, and the active connecting rod and the follower connecting rod are hinged by a hinge shaft, which is slidably inserted into the sliding groove.

[0021] In one embodiment of the housing assembly of this application, a mounting groove is provided on the surface of the handle facing the follower link, and one end of the follower link is rotatably inserted into the mounting groove.

[0022] In one embodiment of the housing assembly of this application, the drive assembly includes two pairs of linkage structures, both of which are connected to the handle and the drive member.

[0023] This application also proposes a speaker, including a housing and a housing assembly as described in any of the preceding claims, the housing assembly comprising:

[0024] The housing has an installation opening on its outer wall;

[0028] The technical solution of this invention includes a combination structure of a drive component and a handle within the housing. The handle is mounted on the mounting opening of the product's housing, allowing the drive component to be connected to the handle in a transmission manner. When the product is placed on a surface, the handle retracts into the mounting opening, resulting in a cleaner product appearance with no handle protruding from the outer wall of the housing. When the product is lifted, the drive component is triggered, causing the handle to extend from the mounting opening for easy access and carrying of the speaker.

[0044] The present invention proposes a housing assembly 100.

[0045] Please refer to Figure 1 and Figure 2 In some embodiments of the housing assembly 100 of this application, the housing assembly 100 includes:

[0046] The housing 10 has an installation opening 11 on its outer wall.

[0047] Handle 20, which is movably disposed in the mounting port 11; and

[0048] A drive assembly 30 may be disposed in the housing 10 and is connected to the handle 20 in a transmission manner.

[0049] When the housing 10 is placed on the mounting surface, the handle 20 retracts into the mounting port 11. When the housing 10 is lifted, the drive assembly 30 is triggered to drive the handle 20 to extend from the mounting port 11.

[0050] The housing assembly 100 proposed in this application can be applied to products such as speakers, tablet computers, televisions, monitors, laptops, and digital photo frames. The housing assembly 100 integrates the various components of the product into a single structure. Specifically, a mounting opening 11 is provided on the outer side wall of the housing 10. The mounting opening 11 is generally located on the top wall 13 of the housing 10, which facilitates the user to lift the handle 20 and keeps the product upright during carrying. Of course, the mounting opening 11 can also be located on the side wall of the housing 10, which is not specifically limited here. The handle 20 is movably provided at the mounting opening 11, so that it can protrude outward from the mounting opening 11 and retract into the mounting opening 11. The drive assembly 30 is connected to the handle 20 and is used to provide the force for the extension and retraction of the handle 20. The drive assembly 30 can be a combination structure of a drive component 33 such as a cylinder or motor and a transmission mechanism such as a linkage mechanism, gear mechanism, lead screw mechanism or slider mechanism, or it can be the counterweight block 333 drive mechanism in the following embodiment, which is not limited here. Simultaneously, the drive assembly 30 can perform corresponding drive operations based on the placement and lifting states of the housing 10. When the housing 10 is lifted from the placement state, the drive assembly 30 drives the handle 20 to push outwards to protrude from the outer wall of the housing 10, making it easier for the user to grip the handle 20 to pick up the product. When the housing 10 is placed on the mounting surface from the lifting state, the drive assembly 30 drives the handle 20 to retract into the mounting opening 11, preventing the handle 20 from protruding and being exposed on the outside of the housing 10, thus keeping the product's appearance simple. The drive assembly 30 can detect the state of the product and the housing 10 by installing motion sensors, pressure sensors, or other detection devices on the product and electrically connecting them to the drive assembly 30. By detecting the speed change of the housing 10 when it is lifted or the interaction force between the housing 10 and the mounting surface, the current state of the housing 10 and the product can be determined, thereby driving the drive assembly 30 to operate. Alternatively, in the following embodiment, a purely mechanical structure using a counterweight 333 to lift and lower the handle 20 can be used to extend or retract it.

[0051] Therefore, it is understood that the technical solution of the present invention provides a combined structure of drive assembly 30 and handle 20 in the housing 10, with the handle 20 installed on the mounting port 11 of the housing 10, so that drive assembly 30 and handle 20 are connected in a transmission manner. When the product is placed on the placement surface, handle 20 retracts into the mounting port 11, making the product appearance relatively neat, without the handle 20 protruding from the outer wall of the housing 10. When the product is lifted, drive assembly 30 is triggered to extend handle 20 from the mounting port 11, so that the user can easily pick up and carry the speaker. That is, the housing assembly 100 proposed by the present invention can adjust the setting state of handle 20 according to the product usage state, improving the flexibility of handle 20 setting, meeting the user's usage needs for handle 20 in different product states, and improving the user experience.

[0052] Please refer to Figure 3 and Figure 5 In some embodiments of the housing assembly 100 of this application, the drive assembly 30 includes:

[0053] Linkage structure 31, comprising an active link 311 and a follower link 313 hinged at their ends, wherein the active link 311 is movably disposed, and the end of the follower link 313 away from the active link 311 is hinged to the handle 20; and

[0054] Drive component 33, which is connected to the active connecting rod 311 in a transmission manner;

[0055] The driving member 33 drives the active connecting rod 311 to rotate so as to cause the handle 20 to extend or retract from the mounting port 11.

[0056] In this embodiment, the drive assembly 30 is configured as a combination of the linkage structure 31 and the drive member 33. Specifically, the linkage mechanism includes an active linkage 311 and a follower linkage 313. One end of the active linkage 311 is connected to the drive member 33, and the other end of the active linkage 311 is hinged to one end of the follower linkage 313. The other end of the follower linkage 313 is hinged to the handle 20. When the drive member 33 drives the active linkage 311 to move, it will drive the follower linkage 313 to move, and then the follower linkage 313 will drive the handle 20 to move. The handle 20 is limited by the mounting port 11 and can only extend and retract axially in the mounting port 11. With this configuration, when the drive member 33 drives the active linkage 311 to move in different directions, it can drive the handle 20 to extend from or retract into the mounting port 11. Through the drive component 33 and the linkage transmission, the motion mode can be changed, thereby changing the motion direction and motion form, so as to optimize and reduce the space occupied by the drive component 30 and reduce the product size.

[0057] It should be noted that in this embodiment, the active linkage 311 is movable, which can be achieved by rotating the end of the active linkage 311 away from the follower linkage 313 to the housing 10, so that the driving member 33 drives the active linkage 311 to rotate, thereby driving the follower linkage 313 to move and thus driving the handle 20 to extend or retract. Alternatively, the end of the active linkage 311 away from the follower linkage 313 can be raised or lowered in a direction away from or near the mounting port 11, and the driving member 33 can drive the end of the active linkage 311 away from the follower linkage 313 to reciprocate up and down, which can also drive the follower linkage 313 to move and drive the handle 20 to enter or exit the mounting port 11.

[0058] It should also be noted that, in this embodiment, the sum of the lengths of the active link 311 and the follower link 313 should be greater than the height of the housing 10, so as to ensure that the handle 20 of the housing assembly 100 can protrude from the mounting opening 11 for easy gripping by the user.

[0059] Please refer to Figure 3 and Figure 5 In some embodiments of the housing assembly 100 of this application, the mounting port 11 is opened on the top wall 13 of the housing 10, and the bottom wall 15 of the housing 10 is provided with a through hole 17, and the driving member 33 is disposed opposite to the through hole 17;

[0060] At least a portion of the drive member 33 can extend and retract from the through hole 17 to drive the active linkage 311 to move.

[0061] In this embodiment, the mounting port 11 is located on the top wall 13 of the housing 10. This arrangement facilitates the user's grip on the handle 20 when it extends out of the mounting port 11 and keeps the product upright while the user is carrying it. Correspondingly, a through hole 17 is provided on the bottom wall 15 of the housing 10, and a portion of the driving component 33 is inserted into the through hole 17. This arrangement allows the through hole 17 to open when the product and housing 10 are lifted. At this time, under the action of gravity, a portion of the telescopic part 333b of the driving component 33 extends outward from the through hole 17, and the active connecting rod 311 is pulled and moves within the housing 10, thereby driving the follower connecting rod 313 to move and cause the handle 20 to protrude from the mounting port 11 for easy gripping by the user. When the product and housing 10 are placed on the mounting surface, the telescopic part 333b is pressed against the mounting surface and retracts from the through hole 17, thereby causing the active linkage 311 to move to drive the follower linkage 313 to retract the handle 20 into the mounting port 11, preventing the handle 20 from protruding from the housing 10 and making the product look simple.

[0062] Furthermore, this embodiment uses a purely mechanical structure, utilizing the gravity of the drive component 33 itself and the interaction force between the drive component 33 and the mounting surface to drive the handle 20 to move. There is no need to install motors, cylinders, or other components, which avoids the situation where the handle 20 cannot extend and retract normally in the event of a power outage, thereby improving the stability of the housing assembly 100 during application.

[0063] Please refer to Figure 3 and Figure 5 In some embodiments of the housing assembly 100 of this application, the drive member 33 is provided with a counterweight 333.

[0064] Understandably, when the product and housing 10 are raised, the drive component 33 primarily descends due to its own weight, thereby driving the active linkage 311 to move and subsequently extending or retracting the handle 20. In this embodiment, the drive component 33 includes a counterweight 333. The counterweight 333 increases the weight of the drive component 33, preventing the handle 20 from failing to extend due to the drive component 33's inability to descend. The counterweight 333 can be located at the top, side, or bottom of the drive component 33, and is not limited here.

[0065] Please refer to Figure 5 and Figure 6 In some embodiments of the housing assembly 100 of this application, the counterweight 333 is disposed at the bottom of the drive member 33. The counterweight 333 includes a limiting part 333a and a telescopic part 333b connected to each other. The limiting part 333a is limited within the housing 10, and the telescopic part 333b protrudes from the surface of the limiting part 333a facing the through hole 17 and is inserted into the through hole 17.

[0066] In this embodiment, the counterweight 333 is positioned at the bottom of the drive member 33, with a portion of the counterweight 333 inserted into the through hole 17, allowing it to extend and retract. This arrangement prevents the rack 331 of the drive member 33 from extending and retracting within the through hole 17, reducing the risk of wear on the rack 331. Furthermore, the counterweight 333 includes a limiting part 333a and a telescopic part 333b connected together. The telescopic part 333b protrudes from one side surface of the limiting part 333a and is inserted into the through hole 17, allowing it to extend and retract within the through hole 17. With this arrangement, when the product and the housing 10 are lifted, the through hole 17 is opened. At this time, under the action of gravity, the drive member 33 causes a portion of the telescopic part 333b to extend outward from the through hole 17. Simultaneously, the active connecting rod 311 is pulled and moves within the housing 10, driving the follower connecting rod 313 to move and cause the handle 20 to protrude from the mounting opening 11 for easy gripping by the user. When the product and housing 10 are placed on the mounting surface, the telescopic part 333b retracts from the through hole 17 under the pressure of the mounting surface. This causes the active linkage 311 to move, driving the follower linkage 313 to retract the handle 20 into the mounting port 11, preventing the handle 20 from protruding from the housing 10 and keeping the product's appearance simple. The counterweight 333 ensures that the drive component 33 has sufficient gravity to resist various resistances encountered during the descent of the drive component 33, such as the reaction force of the linkage structure 31 and the friction of the through hole 17 wall. This ensures that when the housing assembly 100 is raised, the drive component 33 can descend into place so that the handle 20 can extend.

[0067] Please refer to Figure 3 and Figure 4 In some embodiments of the housing assembly 100 of this application, the end of the active link 311 away from the follower link 313 is rotatably disposed, and the drive member 33 drives the active link 311 to rotate so that the handle 20 extends or retracts from the mounting port 11.

[0068] In this embodiment, one end of the active link 311 is rotatably connected to the drive member 33, and the other end of the active link 311 is hinged to one end of the follower link 313. The other end of the follower link 313 is hinged to the handle 20. When the drive member 33 drives the active link 311 to rotate, it will drive the follower link 313 to move, and then the follower link 313 will drive the handle 20 to move. The handle 20 is limited by the mounting port 11 and can only extend and retract axially in the mounting port 11. With this configuration, when the drive member 33 drives the active link 311 to rotate in different directions, it can drive the handle 20 to extend out of or retract into the mounting port 11. In this embodiment, the end of the active link 311 away from the follower link 313 is rotatably connected to the inner wall of the housing 10, so that the end of the active link 311 away from the follower link 313 is kept in a fixed position inside the housing 10. This avoids interference or collision with other components inside the housing 10 during the lifting or lowering process caused by the active link 311 away from the follower link 313 rising or falling with the drive member 33, thereby improving the safety of the housing assembly 100 and the product.

[0069] It should be noted that in this embodiment, the driving component 33 can be a motor, and the output shaft of the motor is directly connected to the active connecting rod 311 or connected through a gear transmission or belt transmission mechanism, etc. The active connecting rod 311 is driven to rotate by driving the rack 331 to slide. The driving component 33 can also be a connection structure of the rack 331 and the counterweight 333, which will not be described in detail here.

[0070] Please refer to Figure 3 and Figure 5 In some embodiments of the housing assembly 100 of this application, the end of the active link 311 away from the follower link 313 is provided with a gear portion 311a, the drive member 33 is provided with a rack 331, the rack 331 meshes with the gear portion 311a, and the drive member 33 is slidably disposed so as to drive the gear portion 311a to rotate during sliding.

[0071] In this embodiment, the driving member 33 and the active connecting rod 311 are connected by a transmission structure consisting of a rack 331 and a gear portion 311. Specifically, a gear portion 311a is provided at the end of the active connecting rod 311 away from the follower connecting rod 313, and a slidable rack 331 is provided on the driving member 33, so that the rack 331 and the gear portion 311a mesh with each other. The sliding of the rack 331 can be driven and controlled by a cylinder or motor, or it can be lifted and lowered by gravity and the interaction force between the driving member 33 and the mounting surface; no limitation is made here. At this time, when the rack 331 slides, it drives the gear portion 311a to rotate, which in turn causes the active connecting rod 311 to rotate, thereby driving the follower connecting rod 313 to extend and retract the handle 20 in the mounting port 11. The drive member 33 and the active connecting rod 311 are connected by the meshing transmission between the gear part 311a and the rack 331. The gear transmission is reliable and has high transmission efficiency, which reduces the loss of the torque input by the drive member 33 during the transmission process and ensures the torque transmission efficiency.

[0072] Furthermore, a through hole 17 is provided on the bottom wall 15 of the housing 10, and a portion of the drive member 33 is inserted into the through hole 17. The rack 331 extends in the vertical direction, i.e., the arrangement direction of the top wall 13 and the bottom wall 15 of the housing 10. At this time, when the product and the housing 10 are placed on the mounting surface, the through hole 17 is blocked by the mounting surface, causing the drive member 33 to abut against the mounting surface. At this time, the handle 20 retracts into the mounting opening 11. When the product and the housing 10 are lifted, the through hole 17 is opened. At this time, the drive member 33 extends outward from the through hole 17 under the action of gravity, and then drives the rack 331 to slide down and drive the gear part 311a to rotate, thereby causing the active connecting rod 311 to rotate to drive the follower connecting rod 313 to push the handle 20 outward from the mounting opening 11, so that the handle 20 protrudes from the top wall 13 of the housing 10 for easy gripping by the user. When the product and housing 10 are placed on the mounting surface, the drive member 33 retracts from the through hole 17 under the pressure of the mounting surface, causing the rack 331 to rise and drive the gear part 311a to rotate. This causes the active connecting rod 311 to rotate, driving the follower connecting rod 313 to retract the handle 20 into the mounting port 11, preventing the handle 20 from protruding from the housing 10 and keeping the product's appearance simple. This embodiment uses a purely mechanical structure, utilizing the weight of the drive member 33 itself and the interaction force between the drive member 33 and the mounting surface to drive the handle 20, eliminating the need for motors, cylinders, or other components. This avoids situations where the handle 20 cannot extend or retract properly in the event of a power outage, improving the stability of the housing assembly 100 during application.

[0073] Please refer to Figure 4In some embodiments of the housing assembly 100 of this application, the linkage structure 31 further includes a rotating shaft 315, which is connected to the inner wall of the housing 10. A limiting groove 315a is formed on the rotating shaft 315, and the end of the active linkage 311 away from the follower linkage 313 is sleeved on the rotating shaft 315 and limited in the limiting groove 315a.

[0074] Understandably, the end of the active link 311 furthest from the follower link 313 is rotatably connected to the housing 10, so that it is driven to rotate by the drive member 33, thereby driving the follower link 313 and the handle 20 to move. Commonly, the active link 311 is rotatably connected to the housing 10 through a rotating shaft 315, at least one end of the rotating shaft 315 is connected to the inner wall of the housing 10, and the end of the active link 311 furthest from the follower link 313 is sleeved on the rotating shaft 315, so that the active link 311 can rotate around the rotating shaft 315. In this embodiment, a limiting groove 315a is provided on the rotating shaft 315. When the active link 311 is sleeved on the rotating shaft 315, it is limited in the limiting groove 315a, preventing the active gear from sliding along the axial direction of the rotating shaft 315, thereby improving the overall structural stability of the drive assembly 30 and the housing assembly 100. The limiting groove 315a can be formed by recessing into the side wall of the rotating shaft 315, or by having two fixing parts 315b protruding from the side wall of the rotating shaft 315 and spaced apart along the axial direction of the rotating shaft 315 to enclose and form the limiting groove 315a. No specific limitation is made here. Preferably, the limiting groove 315a is formed by having two fixing parts 315b protruding from the side wall of the rotating shaft 315 and spaced apart along the axial direction of the rotating shaft 315 to enclose and form the limiting groove 315a. This avoids the structural strength of the rotating shaft 315 from being reduced and easily damaged due to the opening of the limiting groove 315a on the rotating shaft 315. The setting of the fixing parts 315b can also improve the strength of the rotating shaft 315 and increase the service life of the rotating shaft 315.

[0075] Please refer to Figure 3 In some embodiments of the housing assembly 100 of this application, the drive assembly 30 includes two pairs of the connecting rod structures 31, both pairs of the connecting rod structures 31 being connected to the handle 20 and the drive member 33.

[0076] In this embodiment, the drive assembly 30 is provided with two pairs of linkage structures 31. It can be understood that the handle 20 is mostly long and narrow to facilitate user gripping and extraction. In this case, the two pairs of linkage structures 31 are arranged side by side along the length of the handle 20. In each pair of linkage structures 31, the end of the follower link 313 away from the active link 311 is hinged to the handle 20, and the end of the active link 311 away from the follower link 313 is connected to the drive member 33. This allows the drive member 33 to simultaneously drive the two pairs of linkage structures 31 to extend and retract the handle 20 at the mounting port 11. Furthermore, by driving the two pairs of linkage structures 31 simultaneously through the same drive member 33, the actions of the two pairs of linkage structures 31 can be synchronized, avoiding mutual interference when the two pairs of linkage structures 31 drive the handle 20.

[0077] Please refer to Figure 6 In some embodiments of the housing assembly 100 of this application, the handle 20 has a mounting groove 21 on its surface facing the follower link 313, and one end of the follower link 313 is rotatably inserted into the mounting groove 21.

[0078] In this embodiment, a mounting groove 21 is provided on the surface of the handle 20 facing the follower link 313, and one end of the follower link 313 is inserted into the mounting groove 21 and hinged to the handle 20. This arrangement can limit the position of the follower link 313, improve the connection strength between the follower link 313 and the handle 20, and improve the structural stability of the housing assembly 100.

[0079] In some embodiments, the mounting groove 21 has two opposing groove walls. When the handle 20 is retracted to the mounting position, the side wall of the follower link 313 abuts against one of the groove walls. When the handle 20 is extended to the mounting position, the side wall of the follower link 313 abuts against the other groove wall. This arrangement can limit the movement path of the follower link 313.

[0080] Please refer to Figure 3 and Figure 5 In some embodiments of the housing assembly 100 of this application, the inner wall of the housing 10 is provided with a sliding groove 19, and the active connecting rod 311 and the follower connecting rod 313 are hinged by a hinge shaft 317, which is slidably inserted into the sliding groove 19.

[0081] Understandably, in the drive assembly 30, the drive member 33 drives the active link 311 to rotate, which in turn drives the follower link 313 to extend and retract the handle 20. At this time, the hinge position of the active link 311 and the follower link 313 rotates around the rotation axis 315 of the active link 311. In this embodiment, by opening a groove 19 on the inner wall of the housing 10, the movement path of the hinge axis 317 between the active link 311 and the follower link 313 is restricted, making the movement process of the drive assembly 30 more stable and improving the stability of the drive process.

[0082] This application also proposes a speaker, which includes a housing assembly 100 as described in any of the foregoing embodiments. The housing assembly 100 includes a housing 10, a handle 20, and a drive assembly 30. The outer wall of the housing 10 has a mounting opening 11, and the handle 20 is disposed in the mounting opening 11. The drive assembly 30 is disposed in the housing 10 and is kinetically connected to the handle 20. When the housing 10 is placed on a mounting surface, the handle 20 retracts into the mounting opening 11. When the housing 10 is lifted, the drive assembly 30 is triggered to drive the handle 20 to extend from the mounting opening 11. The housing 10 can also be used to mount the speaker, motherboard, and other components of the speaker.

[0083] Understandably, the speaker housing assembly 100 of this application is provided with a combination structure of a drive assembly 30 and a handle 20. The handle 20 is installed on the mounting port 11 of the housing 10, so that the drive assembly 30 and the handle 20 are connected in a transmission manner. When the speaker is placed on the mounting surface, the handle 20 retracts into the mounting port 11, making the speaker appearance relatively clean, and the handle 20 will not protrude from the outer wall of the housing 10. When the speaker is lifted, the drive assembly 30 is triggered to extend the handle 20 from the mounting port 11, so that the user can easily pick up and carry the speaker. That is, the speaker of this invention can adjust the setting state of its handle 20 according to the speaker's usage state, improving the flexibility of the handle 20 setting, so as to meet the user's usage needs for the handle 20 in different product states and improve the user experience.

[0084] Since the speaker proposed in this application applies all the technical solutions of the foregoing embodiments, it has at least all the beneficial effects brought by the foregoing technical solutions, which will not be elaborated here.

[0085] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
