Technical Field

[0001] This invention belongs to the field of radio-controlled clock technology, and in particular relates to a signal receiving device for a radio-controlled clock. Background Technology

[0002] A radio-controlled clock consists of an electronic clock and a radio receiving system. It receives accurate time signals from the national time service center, receives real-time time signals through the radio receiving system, and then displays the time after processing by a CPU. Radio-controlled clocks have advantages such as accurate timekeeping and automatic correction of indication errors, making them widely applicable. However, in existing technologies, the signal receiving device for radio-controlled clocks is usually integrated into the clock's casing. When the clock is installed indoors, thick walls may cause poor signal reception, affecting the clock's accuracy. Therefore, there is an urgent need to research a signal receiving device for radio-controlled clocks to solve this problem. Summary of the Invention

Detailed Implementation

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Specific Implementation Example 1:

[0025] Please see Figure 1-3 As shown, this invention is a signal receiving device for a radio-controlled clock, comprising a radio-controlled clock body 1, a clock control module 2 mounted on the back of the radio-controlled clock body 1, and a signal receiving module 3 disposed outside the clock control module 2. The radio-controlled clock body 1, clock control module 2, and signal receiving module 3 are all conventional components in the art and belong to conventional technology in this field, and will not be described in detail here. The clock control module 2 and the signal receiving module 3 are connected by a wire 4. A winding mechanism 5 for winding or releasing the wire 4 is mounted on the back of the radio-controlled clock body 1. The winding mechanism 5 is disposed around the clock control module 2. In use, by separating the signal receiving module 3 from the radio-controlled clock body 1, connecting the clock control module 2 and the signal receiving module 3 using the wire 4, and then installing the signal receiving module 3 outdoors, and using the winding mechanism 5 to wind or release the wire 4, not only is the signal reception strength of the signal receiving module 3 effectively improved, but the data transmission stability between the clock control module 2 and the signal receiving module 3 is also enhanced, while ensuring the timekeeping accuracy of the radio-controlled clock body 1. Specific Implementation Example 2:

[0027] Based on specific embodiment one, as follows Figure 2 and Figure 4-6As shown, the winding mechanism 5 includes a winding drum 501 screwed to the back of the radio-controlled clock body 1; the winding drum 501 is disposed on the outer periphery of the clock control module 2; the wire 4 passes through the circumferential side wall of the winding drum 501 and the circumferential side wall of the radio-controlled clock body 1; the winding drum 501 has an annular guide rail 5011 at one edge away from the radio-controlled clock body 1; a slider 502 is slidably connected to the annular guide rail 5011; a support strip 503 is radially connected to the slider 502 along the annular guide rail 5011; a limit strip 5031 is vertically welded to one end of the support strip 503 away from the center of the annular guide rail 5011; the limit strip 5031 is arranged parallel to the central axis of the winding drum 501; a limiting space for the wire 4 is formed between the limit strip 5031, the support strip 503, the winding drum 501 and the radio-controlled clock body 1; The slider 502 includes a movable piece 5021 attached to the inner wall of the winding drum 501; a sliding portion 5022 is provided on a surface of the movable piece 5021 away from the center of the annular guide rail 5011; the sliding portion 5022 is slidably connected to the annular guide rail 5011; a support bar 503 is slidably inserted into the movable piece 5021; the other end of the support bar 503 has an extension portion 5032 parallel to the limiting bar 5031; the extension portion 5032 is connected to the movable piece 5021 by a first spring 504; an internal gear ring 505 coaxially arranged with the annular guide rail 5011 is screwed to the inner surface of the movable piece 5021; a transmission gear 506 meshes on the internal gear ring 505; the transmission gear 506 is fixed to the output shaft of a servo motor 507; the servo motor 507 is screwed to the inner wall of the winding drum 501. In use, during the winding or releasing of the wire 4 using the winding mechanism 5, the servo motor 507 drives the internal gear ring 505 to rotate via the transmission gear 506, causing the slider 502 to slide on the annular guide rail 5011. This allows the wire 4, which is interposed between the limiting bar 5031, the bearing bar 503, the winding drum 501, and the radio-controlled clock body 1, to be wound onto the winding drum 501 or released from the winding drum 501, effectively improving the handling of the wire 4. By designing the bearing bar 503 to slide through the movable piece 5021 and the extension 5032 to be connected to the movable piece 5021 via the first spring 504, the limiting bar 5031 can always press against the wire 4, and the distance between the limiting bar 5031 and the winding drum 501 can be adjusted. Specific Implementation Example 3:

[0029] Based on the second specific embodiment, as follows Figure 2-3 and Figure 7As shown, the signal receiving module 3 is installed inside a protective mechanism 6; a positioning mechanism 7 corresponding to the protective mechanism 6 is installed on the back of the radio-controlled clock body 1; the protective mechanism 6 includes a housing 601 and a cover 602 connected to the port of the housing 601 by screws; a sealed space is formed between the housing 601 and the cover 602; the signal receiving module 3 is installed in the sealed space; hanging holes 603 are provided on both opposite edges of the cover 602. In use, by driving a pair of nails into the outdoor wall and then fitting the hanging holes 603 onto the outer periphery of the nails, the signal receiving module 3 can be installed outdoors, effectively ensuring the signal reception strength of the signal receiving module 3.

[0030] Among them, such as Figure 7-8 As shown, a pair of U-shaped limiting protrusions 604 are welded to each of the two opposite sides of the box body 601; the limiting protrusions 604 are located at the edges of the box body 601; the positioning mechanism 7 includes a pair of support plates 701 connected to the back of the radio-controlled clock body 1 by screws; operating bars 702 are provided on each of the opposite sides of the two support plates 701; positioning bars 703 corresponding to the limiting protrusions 604 are vertically welded to both ends of the two operating bars 702; the two pairs of positioning bars 703 are slidably inserted into the two support plates 701 respectively; when the box body 601 is positioned between the two support plates 701, the positioning bars 703 can slide into the limiting protrusions 604; the two support plates 701 and the two operating bars 702 are respectively connected by a pair of second springs 704. When in use, if it is necessary to store the signal receiving module 3, the wire 4 is first wound around the winding mechanism 5, then the box 601 is placed between the two support plates 701, and then the positioning strip 703 is slidably inserted into the limiting protrusion 604, thereby realizing the detachable installation of the protective mechanism 6 on the back of the radio-controlled clock body 1, which makes it convenient for the radio-controlled clock body 1 to be carried or transferred.
