Description

Technical Field

[0001] The utility model relates to the technical field of transmitters, in particular to a wall transmitter. Background Art

[0002] A wall transmitter, also called a wall controller, is a device fixed on the wall to control various smart home devices.

[0003] Chinese patent application number 202311523233.5 discloses a water purifier remote control comprising a base fixed to a wall and a remote control body detachably connected to the base. The remote control body comprises a remote control housing, an operating panel disposed on the housing, and a control system and a wireless communication module disposed within the housing and electrically connected to the operating panel. The operating panel includes a display and operating buttons. The remote control body is battery-powered, and the housing is provided with a battery compartment and a battery cover that seals the compartment.

[0004] To ensure universal installation, the mainstream sizes of wall mount transmitters currently on the market are generally 86mm×86mm, 80mm×80mm, and 50mm×50mm. Wall mount transmitters in the 50mm×50mm size, in particular, can only be powered by button batteries. However, cylindrical batteries (AA batteries) are increasingly replacing button batteries due to their availability, low cost, and high power consumption. Therefore, making it possible for a 50mm×50mm wall mount transmitter to accommodate cylindrical batteries is an urgent problem. Utility Model Content

[0005] The utility model provides a wall transmitter in view of the shortcoming that small-sized wall transmitters in the prior art are difficult to accommodate columnar batteries.

[0006] In order to solve the above technical problems, the present invention is solved by the following technical solutions:

[0007] A wall transmitter includes a housing with an opening at one end and an operating panel covering the housing opening. The housing includes a back panel facing the operating panel. The back panel is recessed toward the operating panel from the back of the operating panel to form a battery cavity for accommodating cylindrical batteries. A battery cover for opening and closing the battery cavity is detachably mounted on the back panel. After the cylindrical battery is installed in the battery cavity, its axis is arranged along the diagonal direction of the back panel.

[0008] This solution places the battery cavity along the diagonal of the backplane, effectively utilizing the maximum diagonal backplane space available in a small transmitter. This ensures structural strength while accommodating cylindrical batteries. After the cylindrical battery is installed in the cavity, the battery cover is attached to the backplane to close the cavity. To replace the cylindrical battery, simply remove the cover and replace the battery.

[0009] Preferably, a sliding engagement structure is provided between the battery cover and the back plate, which enables the battery cover to be engaged or disengaged as the battery cover moves relative to the back plate, and a locking structure is provided to limit the movement of the battery cover relative to the back plate in the disengagement direction after the battery cover slides to engage with the back plate.

[0010] With this solution, the sliding latch structure restricts the battery cover from separating from the back panel along the depth of the case when the battery cover is engaged. The locking structure then restricts movement of the battery cover relative to the back panel in the direction of release, completing installation. To remove the battery cover, the latch structure is unlocked, and the battery cover is disengaged by moving it relative to the back panel in the release direction, allowing the cover to be removed.

[0011] Preferably, the sliding clamping structure includes a through slot extending through the back panel along the depth direction of the casing and a clamping block protruding on the side of the battery cover close to the back panel. The clamping block includes a vertical section and a horizontal section located at the bottom of the vertical section and perpendicular to the vertical section. After the vertical section and the horizontal section pass through the through slot, the horizontal section can be pressed against the front of the back panel close to the operating panel as the vertical section moves in the through slot.

[0012] Using the above solution, when installing the battery cover, the battery cover is placed on the back plate so that the vertical and horizontal sections of the card block pass through the through slot. The battery cover is slid, and the vertical section moves in the through slot, driving the horizontal section to move to the side of the horizontal section close to the battery cover and press against the front of the back plate to achieve snap connection.

[0013] Preferably, the locking structure includes a groove concave on the back side of the back plate and a blocking block convex at the bottom of the groove, the blocking block divides the groove into a movable groove and a card slot, and a protrusion that can be inserted into the movable groove is convex on the side of the battery cover close to the back plate, and when the battery cover slides to be engaged with the back plate, the protrusion is squeezed from the movable groove over the blocking block and then inserted into the card slot for limiting the position. There are an inlet slope on the blocking block and / or the protrusion for causing the protrusion to enter the card slot from the movable groove when the battery cover is subjected to a certain external force, and a retraction slope for causing the protrusion to retract from the card slot to the movable groove.

[0014] With the above solution, when the battery cover is subjected to a certain external force, the battery cover slides in the locking direction, driving the protrusion to be squeezed from the movable slot over the blocking block under the squeezing and sliding cooperation of the introduction inclined surface, and then inserted into the locking slot. In the absence of external force, the protrusion is inserted in the locking slot to limit the movement of the battery cover relative to the back plate in the direction of unhooking; conversely, the battery cover slides in the direction of unhooking, driving the protrusion to be squeezed from the slot over the blocking block under the squeezing and sliding cooperation of the retreat inclined surface, and then inserted into the movable slot to complete unlocking.

[0015] Preferably, an arc-shaped limiting section is provided on one side of the battery cover close to the back plate for limiting the radial movement of the cylindrical battery when the battery cover is closed.

[0016] With the above solution, the arc-shaped limiting section is fitted or gap-matched with the outer ring wall of the cylindrical battery to limit the movement of the cylindrical battery in its radial direction.

[0017] Preferably, the battery cover slides along the diagonal direction of the back panel, and a guide groove is recessed on the back side of the back panel for guiding the sliding of the battery cover. The guide groove is slotted at one end corresponding to the insertion of the battery cover and has a protruding edge at the other end. The shape of the battery cover is consistent with that of the guide groove, and when the battery cover is assembled on the back panel, the side of the battery cover away from the operating panel is on the same plane as the back side of the back panel.

[0018] With this solution, the battery cover slides diagonally along the backplate, ensuring that the obliquely positioned battery cavity is concealed while also reducing the cover's bulk and lowering production costs. The guide groove guides the battery cover's movement, ensuring the smooth operation of the sliding and locking mechanisms. The shape of the battery cover matches the guide groove, ensuring that after installation, the cover neither protrudes nor dents relative to the housing, resulting in a smoother and more aesthetically pleasing design for the entire transmitter.

[0019] Due to the adoption of the above technical solution, the present invention has significant technical effects: the battery cavity is arranged along the diagonal direction of the back plate, effectively utilizing the maximum space in the diagonal direction of the back plate in the small-sized transmitter, and can accommodate the cylindrical battery under the premise of ensuring the structural strength of the transmitter.

[0031] The present invention is described in further detail below with reference to the accompanying drawings and embodiments.

[0032] Example

[0033] A wall transmitter, referring to Figures 1 to 10 , including a casing 1 with an opening at one end and an operation panel 2 covering the opening of the casing 1. A control module and a wireless communication module electrically connected to the operation panel 2 are provided in the casing 1. The above structure, connection method and control method are all existing technologies and will not be elaborated here.

[0034] The housing 1 includes a back panel 101 that faces the operating panel 2. The side of the back panel 101 facing away from the operating panel 2 is the back side, and the side of the back panel 101 facing the operating panel 2 is the front side. The battery cover 5 slides diagonally along the back panel 101. A guide groove 14 is formed on the back side of the back panel 101, recessed toward the operating panel 2. The guide groove 14 allows the battery cover 5 to slide back and forth diagonally along the back panel 101. The end of the guide groove 14 corresponding to the insertion point of the battery cover 5 is slotted, facilitating the battery cover 5 to slide into the guide groove 14. The other end of the guide groove 14, away from the slot, is configured as a protruding angle. After the guide groove 14 and the battery cover 5 are assembled, the side of the battery cover 5 facing away from the back panel 101 is flush with the back side of the back panel 101. Since the shape of the battery cover 5 is consistent with the guide groove 14, the flatness between the battery cover 5 and the back panel 101 is ensured after assembly, ensuring an aesthetically pleasing appearance.

[0035] A battery cavity 3 is formed on the bottom of the guide slot 14, recessed toward the operating panel 2, to accommodate a cylindrical battery 4. When installed in the cavity 3, the cylindrical battery 4's axis is aligned with and parallel to the diagonal of the backplate 101. In other words, the axis of the cylindrical battery 4 is positioned along the diagonal of the backplate 101. In this embodiment, the transmitter measures 50 mm x 50 mm, the cylindrical battery 4 is a AAA battery, and the backplate 101 of the transmitter is square, so the angle between the AAA battery and the backplate 101 is 45°.

[0036] A sliding engagement structure is provided between the battery cover 5 and the guide slot 14, enabling engagement or disengagement of the two as they move relative to each other. The sliding engagement structure includes a through slot 6 extending through the bottom surface of the guide slot 14 along the depth direction of the housing 1. A latch block 7 is provided protruding from the side of the battery cover 5 near the back panel 101. The latch block 7 includes a vertical section 701 protruding toward the operating panel 2 on the side of the battery cover 5 near the back panel 101, and a horizontal section 702 located at the bottom of the vertical section 701 and perpendicular to the vertical section 701. The horizontal section 702 is parallel to the battery cover 5. After the vertical section 701 and the horizontal section 702 pass through the through slot 6, the battery cover 5 is slid, and the vertical section 701 moves within the through slot 6, driving the horizontal section 702 to move to the side of the horizontal section 702 near the battery cover 5, where it presses against the front of the back panel 101, achieving engagement.

[0037] A locking structure is also provided between the battery cover 5 and the back plate 101. When the battery cover 5 slides and engages with the back plate 101, the locking structure restricts the battery cover 5 from moving relative to the back plate 101 in the direction of releasing the engagement. The locking structure includes a groove 8 recessed on the back of the back plate 101 and a stopper 9 protruding from the bottom of the groove 8. The stopper 9 divides the groove 8 into a movable groove 801 and a locking groove 802. A protrusion 10 is provided on the side of the battery cover 5 near the back plate 101, which is inserted into the movable groove 801. When the battery cover 5 slides and engages with the back plate 101, the protrusion 10 squeezes from the movable groove 801, passes over the stopper 9, and then inserts into the locking groove 802 to limit the position.

[0038] The side wall of the blocking block 9 near the movable groove 801 is arranged to gradually move away from the movable groove 801 from away from the battery cover 5 to close to the battery cover 5, forming an introduction slope 11. The protrusion 10 also has an introduction slope 11 that squeezes and slides with the introduction slope 11 of the blocking block 9 when the battery cover 5 is subjected to a certain external force, so that the protrusion 10 enters the card slot 802 from the movable groove 801.

[0039] The side wall of the blocking block 9 near the slot 802 is arranged to gradually move away from the slot 802 from away from the battery cover 5 to closer to the battery cover 5, forming a retraction slope 12. There is also a retraction slope 12 on the protrusion 10, which squeezes and slides with the retraction slope 12 of the blocking block 9 when the battery cover 5 is subjected to a certain external force, so that the protrusion 10 retreats from the slot 802 to the movable slot 801.

[0040] An arc-shaped limiting section 13 is provided on one side of the battery cover 5 close to the back plate 101. When the battery cover 5 is closed, the arc-shaped limiting section 13 is in contact with or has a clearance fit with the outer ring wall of the cylindrical battery 4 to limit the radial movement of the cylindrical battery 4.

[0041] The cylindrical battery 4 is installed in the battery cavity 3, and the battery cover 5 is placed in the guide groove 14, so that the locking block 7 is inserted into the through groove 6 and the protrusion 10 is inserted into the movable groove 801. External force is applied to the battery cover 5, driving the battery cover 5 in the locking direction. The horizontal section 702 moves to the side closest to the battery cover 5, pressing against the front of the back plate 101 to achieve a locking connection. That is, the back plate 101 is clamped between the horizontal section 702 and the battery cover 5, preventing the battery cover 5 from separating from the back plate 101 along the depth direction of the housing 1. At the same time, the protrusion 10 and the blocking block 9, under the extrusion and sliding cooperation of the guide bevel 11, squeeze the protrusion 10 from the movable groove 801, pass the blocking block 9, and then insert into the locking groove 802, restricting the battery cover 5 from moving in the unlocking direction relative to the back plate 101, thereby locking the battery cover 5 and completing the installation of the battery cover 5.

[0042] When replacing the cylindrical battery 4, external force is applied to the battery cover 5 to drive the battery cover 5 to move in the direction of releasing the engagement. The protrusion 10 and the blocking block 9 cooperate with the squeezing and sliding of the retracted inclined surface 12, so that the protrusion 10 is squeezed from the card slot 802 to pass over the blocking block 9 and is located in the movable slot 801. At the same time, the horizontal section 702 of the card block 7 moves to disengage from the back plate 101. The battery cover 5 can be removed to replace the cylindrical battery 4.
