Description

Technical Field

[0001] This application relates to the field of electrical equipment technology, and in particular to a sliding unlocking mechanism. Background Technology

[0002] In household appliances or electronic products, the casing often has recessed compartments, which are usually covered by quick-release covers. These recessed compartments can be used to accommodate accessories such as batteries and control components.

[0003] Taking a remote control for a household appliance as an example, the remote control housing has a recessed area for accommodating batteries, and a quick-release cover (also called a battery cover) is fitted over the opening of this recessed area. One side of the quick-release cover has an insertion block, and the other side has a spring-loaded latch. The insertion block of the quick-release cover is inserted into the housing. The housing has a limiting groove for accommodating the spring-loaded latch, and also has an abutment groove that communicates with the limiting groove. When removing the quick-release cover, the user needs to place their fingers in the abutment groove and use their fingers to lift the spring-loaded latch upwards to separate the quick-release cover from the housing.

[0004] Because a recessed groove needs to be provided on the casing so that users can pry open the quick-release cover with their fingers, creating such a groove would affect the product's aesthetics. Furthermore, users have to use their fingers to pry open the quick-release cover, which is very inconvenient and negatively impacts the user experience. Utility Model Content

[0005] To facilitate the separation of the cover plate from the housing by staff, this application provides a sliding unlocking mechanism.

[0006] This application provides a sliding unlocking mechanism, which adopts the following technical solution:

[0007] A sliding unlocking mechanism includes a housing, a cover plate, a bolt, a lock cylinder structure, and an unlocking button. The housing has an internal receiving chamber and an external receiving groove. The cover plate covers the opening of the receiving groove. The bolt is fixed to the cover plate near the housing. The lock cylinder structure is fixed within the receiving chamber. The housing has a first through hole through which the bolt passes, and the bolt is fixedly connected to the lock cylinder structure. The housing also has a second through hole through which the unlocking button passes, and the unlocking button is fixedly connected to the lock cylinder structure. Sliding the unlocking button separates the bolt from the lock cylinder structure.

[0008] By adopting the above technical solution, when the cover plate is placed on the groove of the receiving groove, the lock tongue and the lock cylinder structure are fixedly connected, thereby fixing the cover plate to the housing; when the cover plate needs to be separated from the housing, the unlocking button slides to drive the lock tongue to separate from the lock cylinder structure, thereby making it easier for the staff to separate the cover plate from the housing, improving the user experience, and improving the aesthetics of the product.

[0009] Optionally, the lock cylinder structure includes a fixed base, a locking rod, and a return spring; the fixed base is fixed to the housing, and the fixed base has a stepped groove, which, along the direction away from the unlock button, sequentially includes a first stepped groove and a second stepped groove; the locking rod is disposed in the first stepped groove, and the locking rod is slidably connected to the bottom wall of the first stepped groove, and the locking rod is fixedly connected to the unlock button, which drives the locking rod to slide; the locking rod has a first insertion post on the side near the fixed base, and the end of the return spring is sleeved on the outer periphery of the first insertion post; the locking rod has an opening for the lock tongue to pass through. The limiting through hole includes a locking tongue comprising a first locking member inserted into a second stepped groove, and a second locking member fixedly disposed on the side wall of the limiting through hole; a return spring is disposed within the second stepped groove, and a fixed base is provided with a second insertion post within the second stepped groove, with the end of the return spring sleeved on the outer periphery of the second insertion post; the return spring is fixedly disposed between the first insertion post and the second insertion post; when the cover plate covers the opening of the receiving groove, the return spring forces the second locking member to move toward the first locking member, and the second locking member is disposed on the side of the first locking member close to the cover plate.

[0010] By adopting the above technical solution, when the lock cylinder is inserted into the stepped groove of the fixed base, the return spring drives the second locking member to be positioned on the side of the first locking member near the cover plate, thereby fixing the bolt to the lock cylinder structure and achieving a fixed connection between the cover plate and the housing. When the cover plate needs to be separated from the housing, the user drives the unlock button to move in the unlocking direction, causing the second locking member to be offset from the first locking member, allowing the bolt to move freely out of the housing, thereby achieving the separation of the cover plate from the housing.

[0011] Optionally, the first locking member has a first locking guide surface on the side near the second locking member, and the second locking member has a second locking guide surface on the side near the first locking member. When the first locking member is inserted into the second stepped groove, the first locking member is positioned on the moving path of the second locking member, and the second locking guide surface of the second locking member abuts against the first locking guide surface. The first locking member forces the second locking member to move in the unlocking direction. When the first locking guide surface separates from the second locking guide surface, the return spring forces the second locking member to move towards the first locking member, and the locking member blocks the moving path of the first locking member.

[0012] By adopting the above technical solution, under normal conditions, the return spring drives the second locking member to be positioned on the moving path of the first locking member. When the cover plate and the housing need to be fixedly connected, the first locking member moves towards the second groove of the fixed base, and the first locking guide surface of the first locking member abuts against the second locking guide surface of the second locking member. The first locking member forces the second locking member and the locking rod to slide, so that the first locking member is inserted into the second stepped groove of the fixed base. Subsequently, the return spring forces the second locking member to move towards the first locking member, and the locking member blocks the moving path of the first locking member, thereby realizing the fixed connection between the lock tongue and the lock cylinder structure, and the fixed connection between the cover plate and the housing.

[0013] Optionally, the first locking member is further provided with a third locking guide surface, and when the return spring forces the second locking member to move toward the first locking member, the second locking member slides along the second locking guide surface.

[0014] By adopting the above technical solution, a third locking guide surface is provided on the first locking member to facilitate the sliding of the second locking member onto the moving path of the first locking member.

[0015] Optionally, the locking tongue further includes a first unlocking component, and a second unlocking component is fixedly provided on the side wall of the limiting through hole. The first unlocking component has a first unlocking guide surface on the side near the second unlocking component, and the second unlocking component has a second unlocking guide surface on the side near the first unlocking component. When the unlocking button drives the locking rod to move in the unlocking direction, the second unlocking guide surface of the second unlocking component abuts against the first unlocking guide surface, and the second unlocking component forces the first unlocking component away from the housing.

[0016] By adopting the above technical solution, when the unlock button drives the locking rod to move in the unlocking direction, in addition to the first locking member separating from the second locking member, the second unlocking member also moves towards the first unlocking member, and the second unlocking member forces the second unlocking member to move away from the housing, thereby causing the cover to eject and separate from the housing, so that the staff can quickly and conveniently separate the cover from the housing.

[0017] Optionally, the bottom wall of the second step groove is provided with a first clearance notch, which is located within the vertical projection plane of the reset spring.

[0018] By adopting the above technical solution, by opening a first clearance notch in the bottom wall of the second step groove, the friction between the reset spring and the fixed base is reduced, thereby making it easier for the user to slide the unlock button and improving the user experience.

[0019] Optionally, the bottom wall of the second step groove is provided with a second clearance notch, which is located on the vertical projection surface of the second insertion post.

[0020] By adopting the above technical solution, a second clearance notch is provided on the bottom wall of the second step groove, which makes it easier for the staff to insert the end of the reset spring into the second insertion post.

[0021] Optionally, the unlock button has an anti-slip protrusion on the side away from the housing.

[0022] By adopting the above technical solution, and by setting anti-slip protrusions on the unlock button, the friction between the user and the unlock button is increased, so that the staff can slide the unlock button.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. When the cover plate is placed on the groove of the receiving recess, the lock tongue and the lock cylinder structure are fixedly connected, thereby fixing the cover plate to the housing; when the cover plate needs to be separated from the housing, the unlock button slides to drive the lock tongue to separate from the lock cylinder structure, thereby making it easier for the staff to separate the cover plate from the housing, improving the user experience, and improving the aesthetics of the product.

[0025] 2. Under normal conditions, the return spring drives the second locking member to be positioned on the moving path of the first locking member. When the cover plate and the housing need to be fixedly connected, the first locking member moves towards the second groove of the fixed base. The first locking guide surface of the first locking member abuts against the second locking guide surface of the second locking member. The first locking member forces the second locking member and the locking rod to slide, so that the first locking member is inserted into the second stepped groove of the fixed base. Subsequently, the return spring forces the second locking member to move towards the first locking member, and the locking member blocks the moving path of the first locking member, thereby realizing the fixed connection between the lock tongue and the lock cylinder structure, and the fixed connection between the cover plate and the housing.

[0026] 3. When the unlock button drives the locking lever to move in the unlocking direction, in addition to the first locking member separating from the second locking member, the second unlocking member also moves toward the first unlocking member, and the second unlocking member forces the second unlocking member to move away from the housing, thereby causing the cover to eject and separate from the housing, so that the operator can quickly and conveniently separate the cover from the housing.

[0039] The following is in conjunction with the appendix Figure 1-11 This application will be described in further detail.

[0040] This application discloses a sliding unlocking mechanism. (Refer to...) Figure 1 The sliding unlocking mechanism includes a housing 1, a cover plate 2, a latch 3, a lock cylinder structure 4, and an unlocking button 5. In this embodiment, the sliding unlocking mechanism is applied to a remote control for a household appliance.

[0041] Reference Figure 1 The housing 1 includes an upper housing 11 and a lower housing 12. The upper housing 11 and the lower housing 12 are arranged to form a receiving chamber 13. The outer periphery of the upper housing 11 is provided with a receiving groove 111. The cover plate 2 is placed on the groove of the receiving groove 111.

[0042] Reference Figure 1 The latch 3 is fixed to the cover plate 2 near the housing 1, and the lock cylinder structure 4 is fixed in the receiving chamber 13. The upper housing 11 has a first connecting hole 112 through which the latch 3 passes, and the latch 3 is fixedly connected to the lock cylinder structure 4. The upper housing 11 also has a second connecting hole 113 through which the unlocking button 5 passes, and the unlocking button 5 is fixedly connected to the lock cylinder structure 4. The unlocking button 5 slides to separate the latch 3 from the lock cylinder structure 4. In this embodiment, when the unlocking button 5 moves to the right, the latch 3 separates from the lock cylinder structure 4, thereby causing the cover plate 2 to eject from the housing 1.

[0043] Reference Figure 2 , Figure 2 This diagram illustrates the fixed connection between cover plate 2 and housing 1; see reference. Figure 3 , Figure 3The diagram illustrates the state of the cover plate 2 after it is ejected and separated from the housing 1. When the cover plate 2 is placed over the groove 111, the latch 3 is fixedly connected to the lock cylinder structure 4, thus securing the cover plate 2 to the housing 1. When the cover plate 2 needs to be separated from the housing 1, the unlock button 5 slides to drive the latch 3 to separate from the lock cylinder structure 4, making it easier for staff to separate the cover plate 2 from the housing 1, improving the user experience and enhancing the product's aesthetics.

[0044] Reference Figure 3 and Figure 4 The cover plate 2 has a plugging protrusion on one side, and the upper housing 11 has a plugging groove for the plugging protrusion to be plugged in and fixed. Two locking tongues 3 are spaced apart at the other end of the cover plate 2. Each locking tongue 3 includes a first locking member 31 and a first unlocking member 32, which are integrally formed. The first locking member 31 is used to fix the cover plate 2 to the housing 1, and the first unlocking member 32 is used to separate the cover plate 2 from the housing 1. The first locking member 31 has a first locking guide surface 311, and the first unlocking member 32 has a first locking guide surface 311. The inclination directions of the first locking guide surface 311 and the first unlocking guide surface 321 are opposite.

[0045] Reference Figure 5 and Figure 6 The lock cylinder structure 4 includes a fixed base 41, a lock rod 42, and a return spring 43.

[0046] Reference Figure 5 and Figure 6 The fixed base 41 is fixed to the housing 1. The fixed base 41 is provided with a stepped groove 411. Along the direction away from the unlock button 5, the stepped groove 411 includes a first stepped groove 4111 and a second stepped groove 4112. The locking rod 42 is disposed in the first stepped groove 4111 and is slidably connected to the bottom wall of the first stepped groove 4111. After the unlock button 5 passes through the second connecting hole 113, the locking rod 42 is fixedly connected to the unlock button 5, and the unlock button 5 drives the locking rod 42 to slide. The unlock button 5 is provided with an anti-slip protrusion 51 on the side away from the housing 1, thereby increasing the friction between the user and the unlock button 5, so that the operator can slide the unlock button 5.

[0047] Reference Figure 5 and Figure 6 The locking rod 42 has a limiting through hole 421 for the locking tongue 3 to pass through. After the locking tongue 3 passes through the first connecting hole 112 and the limiting through hole 421 in sequence in the upper housing 11, the locking tongue 3 is set in the second stepped groove 4112 of the fixed base 41. In this embodiment, the second stepped groove 4112 is provided with several reinforcing plates to improve the overall rigidity of the fixed base 41.

[0048] Reference Figure 5 and Figure 6The reset spring 43 is disposed in the second step groove 4112. The locking rod 42 is provided with a first insertion post 6 on the side near the fixed base 41. The end of the reset spring 43 is sleeved on the outer periphery of the first insertion post 6. The fixed base 41 is provided with a second insertion post 7 in the second step groove 4112. The end of the reset spring 43 is sleeved on the outer periphery of the second insertion post 7. The reset spring 43 is fixed between the first insertion post 6 and the second insertion post 7.

[0049] Reference Figure 6 It is worth noting that the bottom wall of the second-step groove 4112 has a first clearance notch 412, which is located within the vertical projection plane of the return spring 43. The first clearance notch 412 reduces the friction between the return spring 43 and the fixed base 41, thereby facilitating the user to slide the unlock button 5 and improving the user experience. The bottom wall of the second-step groove 4112 has a second clearance notch 413, which is located within the vertical projection plane of the second insertion post 7. The second clearance notch 413 in the bottom wall of the second-step groove 4112 facilitates the insertion of the end of the return spring 43 into the second insertion post 7.

[0050] Reference Figure 6 and Figure 7 The sidewall of the limiting through hole 421 is fixed with a second locking member 422, which cooperates with the first locking member 31. The first locking member 31 is provided with a first locking guide surface 311 on the side near the second locking member 422, and the second locking member 422 is provided with a second locking guide surface 4221 on the side near the first locking member 31.

[0051] Reference Figure 6 and Figure 7 The sidewall of the limiting through hole 421 is fixed with a second unlocking member 423. The first unlocking member 32 is provided with a first unlocking guide surface 321 on the side near the second unlocking member 423, and the second unlocking member 423 is provided with a second unlocking guide surface 4231 on the side near the first unlocking member 32.

[0052] Reference Figure 8 and Figure 9When the first locking member 31 is inserted into the second stepped groove 4112, the first locking member 31 is positioned on the moving path of the second locking member 422. The second locking guide surface 4221 of the second locking member 422 abuts against the first locking guide surface 311, and the first locking member 31 forces the second locking member 422 to move in the unlocking direction. When the first locking guide surface 311 and the second locking guide surface 4221 separate, the return spring 43 forces the second locking member 422 to move towards the first locking member 31. The second locking member 422 is positioned on the side of the first locking member 31 near the cover plate 2, and the locking member blocks the moving path of the first locking member 31. Meanwhile, the first locking member 31 is also provided with a third locking guide surface 312. When the return spring 43 forces the second locking member 422 to move toward the first locking member 31, the second locking member 422 slides along the second locking guide surface 4221. By providing the third locking guide surface 312 on the first locking member 31, the second locking member 422 can slide onto the moving path of the first locking member 31.

[0053] Reference Figure 10 and Figure 11 When the unlock button 5 drives the locking lever 42 to move in the unlocking direction, the second locking member 422 is offset from the first locking member 31, allowing the locking tongue 3 to move freely out of the housing 1, thereby separating the cover plate 2 from the housing 1. Simultaneously, the second unlocking guide surface 4231 of the second unlocking member 423 abuts against the first unlocking guide surface 321, and the second unlocking member 423 forces the first unlocking member 32 away from the housing 1.

[0054] The implementation principle of a sliding unlocking mechanism in this application embodiment is as follows:

[0055] Reference Figures 1 to 11 Under normal conditions, the return spring 43 drives the second locking member 422 to be positioned on the moving path of the first locking member 31. When the cover plate 2 and the housing 1 need to be fixedly connected, the first locking member 31 moves towards the second groove of the fixed base 41. The first locking guide surface 311 of the first locking member 31 abuts against the second locking guide surface 4221 of the second locking member. The first locking member 31 forces the second locking member 422 and the locking rod 42 to slide, so that the first locking member 31 is inserted into the second stepped groove 4112 of the fixed base 41. Subsequently, the return spring 43 forces the second locking member 422 to move towards the first locking member 31, and the locking member blocks the moving path of the first locking member 31, thereby realizing the fixed connection between the lock tongue 3 and the lock cylinder structure 4, and the fixed connection between the cover plate 2 and the housing 1.

[0056] When the unlock button 5 drives the locking lever 42 to move in the unlocking direction, the second locking member 422 is offset from the first locking member 31, allowing the locking tongue 3 to move freely out of the housing 1, thus separating the cover 2 from the housing 1. Simultaneously, the second unlocking member 423 also moves towards the first unlocking member 32, and the second unlocking member 423 is forced to move away from the housing 1, thereby causing the cover to eject and separate from the housing 1, allowing workers to quickly and easily separate the cover 2 from the housing 1.

[0057] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
