Description

Technical Field

[0001] This utility model relates to the technical field of charging equipment, and in particular to a desktop charging device. Background Technology

[0002] Current retractable power outlets utilize plugs to transmit current to connected devices, supplemented by other charging options such as USB ports and wireless chargers. They can also be equipped with media (typically HDMI or similar interfaces) or data connectivity devices (such as RJ11 or RJ45 slots). The development of low-DC operating appliances and communication devices has led to an increase in the use of USB ports, while end-consumer demand for more outlets has decreased accordingly. Desktop charging solutions typically have a cuboid-shaped recessed housing that can accommodate one or more outlets within a defined space. Connecting cables power these outlets, with one end connected to the outlet and the other end equipped with a plug. USB charging ports require a larger PCBA (Printed Circuit Board Assembly) to convert AC power to DC power used by USB. Desktop charging solutions embedded in tabletop holes use mechanisms such as spring force or locking / unlocking systems to keep the USB ports and outlets in an accessible position when lifted. Due to safety standards, the live parts of the outlet and the coupling parts with the plug must be placed vertically or nearly vertically to the desktop surface. Therefore, the space between the outlet area and the edge of the hole must be kept clear to accommodate plug coupling. Therefore, the embedded movement of the charging body must take this blank area into account, which limits the available space for mechanical and electronic components inside the socket.

[0003] For the reasons mentioned above, the height of desktop charging devices often exceeds the thickness of the furniture, due to the combination of the surface area of ​​the socket and the size of the PCBA required for the USB port. Furthermore, concealing the socket and PCBA in an embedded solution negatively impacts heat dissipation when the device is under full load. This problem is particularly pronounced when using standard 60mm cable access holes. Ideally, the depth of desktop charging devices should not exceed 60mm, which is the typical maximum thickness of a tabletop. This solution is very convenient for consumers because it requires no surface modification and avoids interference with other elements under the table, such as drawers, pipes, or conduits. Conversely, if the diameter of the desktop charging device is larger than the standard surface opening, the tabletop cable access hole must be adjusted so that these devices can be directly accessed by lifting the handle upwards. This solution typically requires a custom drilling tool of a specific diameter, which can be difficult to find or obtain. Utility Model Content

[0011] The PCBA used to power the USB port is fixed inside the housing and does not move with the main body, and is connected to the USB port by a wire.

[0012] Specifically, the centerline of the desktop hole is on the same straight line as the X-axis.

[0013] In some embodiments, the desktop charging device is integrated into a desktop hole with a standard width of 60mm on the desktop surface.

[0014] Specifically, after the main body is lifted, the creepage distance between the PCBA and the live parts is increased, the heat generated during the charging of electrical appliances or smartphones is dissipated, and electromagnetic interference with other devices is reduced.

[0015] The above design, which allows for lifting or hiding along the X-axis, provides flexible use of desktop space. It can be hidden when not needed and lifted for use when required. The desktop hole integration makes installation simpler and more aesthetically pleasing. It also features a USB port and a socket to meet various charging needs.

[0024] In some embodiments, the main body includes an upper portion, a middle portion, and a lower portion arranged sequentially from top to bottom; the cover is fixed to the upper portion; the upper portion and the lower portion move relative to the middle portion and along the X-axis; the top end of the locking lever is connected to the upper portion, and the bottom end is connected to the lower portion; and when the cover is pressed, the upper portion moves downward relative to the middle portion until the top end of the upper portion abuts against the top end of the middle portion, thereby causing the upper portion and the middle portion to move downward synchronously until the bottom end of the middle portion abuts against the bottom end of the lower portion. That is, the upper and lower halves contract relative to the middle part to save space; during this process, the locking rod is driven to move down and lock in the locked position; at the same time, the middle part is provided with a first elastic element and a second elastic element. The first elastic element can give the upper half a force that always tends to move upward, and the second elastic element can give the lower half a force that always tends to move downward; after the locking rod disengages from the locked position, the first and second elastic elements can drive the middle part and the upper half to move upward relative to each other, returning to the initial state, that is, the upper half and the lower half unfold relative to the middle part.

[0025] In some embodiments, one end of the spring is fixed to the bottom of the housing, and the other end is connected to the bottom end of the body, providing stable elastic support.

[0029] In some embodiments, a locking part is provided in the guide rail, and the bottom end of the locking part is recessed upward to form the locking position; a tapered groove is provided on the outer wall of the main body, the locking rod is installed in the tapered groove, and its bottom end is a free end, which can move along the guide rail in the locking member to disengage or lock in the locking position.

[0030] By adopting the above scheme, the movement of the locking lever is precisely controlled by the guide rail, and it can be disengaged or locked in the locked position, thereby improving the reliability of locking / releasing.

[0031] In some embodiments, the housing is provided with a limiting portion for restricting the movement of the body along the X-axis.

[0032] By adopting the above solution, the setting of the limiting part prevents the main body from moving excessively, ensuring safety in use. At the same time, it prevents the main body from completely detaching from the shell, increasing the product's durability.

[0033] In some embodiments, the limiting portion is at least one groove formed by an inward recess in the inner wall of the housing, the groove being arranged along the X-axis; the body is provided with a protrusion that can fit into the groove.

[0034] Specifically, when the main body moves upward along the X-axis until the top of the protrusion abuts against the top of the groove, the main body is in a fully raised state.

[0035] The above scheme, with its combination of grooves and protrusions, enables trajectory control of the main body's movement. This simple yet effective constraint method facilitates manufacturing and maintenance.

[0036] In some embodiments, the housing can be fixed to the desktop by a locking ring after passing through a desktop hole; and the top of the housing is provided with an outer cover portion that can abut against the desktop.

[0037] Specifically, the locking ring and the outer casing are threaded together, allowing the desktop charging device to be assembled on desktops of various thicknesses.

When the cover 105 is pressed, the upper portion 1061 moves downward relative to the middle portion 1062 until the top end of the upper portion 1061 abuts against the top end of the middle portion 1062, thereby causing the upper portion 1061 and the middle portion 1062 to move downward synchronously until the bottom end of the middle portion 1062 abuts against the bottom end of the lower portion 1063. The upper half 1061 and the lower half 1063 retract relative to the middle half 1062 to save space; during this process, the locking lever 400 is driven to move downwards and lock in the locking position 2021a; at the same time, the middle half 1062 is provided with a first elastic element 1064 and a second elastic element 1065. The first elastic element 1064 can give the upper half 1061 a force that always tends to move upwards, and the second elastic element 1065 can give the lower half 1063 a force that always tends to move downwards; after the locking lever 400 disengages from the locking position 2021a, the first elastic element 1064 and the second elastic element 1065 can drive the middle half 1062 and the upper half 1061 to move upwards relative to each other, returning to the initial state, that is, the upper half 1061 and the lower half 1063 unfold relative to the middle half 1062. In some embodiments, one end of the spring 300 is fixed to the bottom of the housing 200, and the other end is connected to the bottom end of the main body 100, providing stable elastic support.
