Description

Technical Field

[0001] This application relates to the field of light sign technology, and more specifically to a light sign battery box structure. Background Technology

[0002] Light sticks are a common type of light sign. Some light sticks have LED beads arranged in the shape of text or graphics, allowing them to display illuminated text or graphics when powered on. These light sticks have a plug with contacts on its surface. The plug is inserted into the power terminal of the battery compartment, and then into a contact spring clip inside the terminal. The contacts make contact with the contact spring clip to transfer power. The contact spring clip is usually fixed to a small circuit board. If too much force is used when inserting or removing the light stick's plug from the contact spring clip, the small circuit board can easily shift or loosen, making it difficult to connect subsequent light sticks. This needs improvement. Utility Model Content

[0021] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0024] At least one embodiment of this application is a light sign battery box structure, the specific structure of which is as follows: Figures 1 to 5 As shown. Combined with Figure 1 and Figure 2 As shown, the battery box has a power receiving cavity 13 for the plug 91 of the light sign 90 to be inserted and draw power. A main circuit board 31 is fixed inside the battery box. A spring clip 33 and a secondary circuit board 32 are provided inside the power receiving cavity 13. The spring clip 33 is fixed to the side of the secondary circuit board 32 facing the main circuit board 31. In a specific implementation, the spring clip 33 is made of copper. The side of the secondary circuit board 32 is fixedly connected to the inner wall of the power receiving cavity 13, forming a fixed connection with the main circuit board 31, and the secondary circuit board 32 is perpendicular to the main circuit board 31. In this embodiment, the battery box structure directly fixes the secondary circuit board 32, which is fixed to the spring clip 33, to the inner wall of the power receiving cavity 13. Simultaneously, the secondary circuit board 32 is also fixedly connected to the main circuit board 31, enhancing the fixation of the secondary circuit board 32. Inserting or removing the plug 91 of the light sign 90 relative to the spring clip 33 will not cause displacement or loosening of the secondary circuit board 32, improving the stability of the product.

[0025] In some embodiments, such as Figure 2 As shown, the inner walls of the two opposite sides of the electrical cavity 13 are respectively provided with parallel guide grooves 111. The two sides 323 of the sub-circuit board 32 are respectively inserted into the guide grooves 111 for fixation. When the plug 91 of the light sign 90 is inserted into / pulled out of the spring clip 33, the sub-circuit board 32 will not move up and down relative to the electrical cavity 13 when it is subjected to the force of the plug 91.

[0026] In some embodiments, combined with Figure 1 and Figure 2As shown, a limiting plate 20 is fixed between the sub-circuit board 32 and the main circuit board 31, and the limiting plate 20 is fixedly connected to the sub-circuit board 32 and the main circuit board 31 respectively. The limiting plate 20 is located at the inner corner formed by the sub-circuit board 32 and the main circuit board 31, and the limiting plate 20 is perpendicular to the sub-circuit board 32 and the main circuit board 31 respectively. The two adjacent sides of the limiting plate 20 are respectively attached to the sub-circuit board 32 and the main circuit board 31. The limiting plate 20 is not used for electrically connecting the sub-circuit board 32 and the main circuit board 31. In some embodiments, combined with Figure 1 and Figure 2 As shown, the limiting plate 20 is fixedly connected to the sub-circuit board 32 and the main circuit board 31 by soldering. Specifically, the limiting plate 20 has two copper sheets 203 on its surface, located near the main circuit board 31. The limiting plate 20 is fixedly connected to the main circuit board 31 and the sub-circuit board 32 by soldering the copper sheets 203 to them. The limiting plate 20 can be a copper-clad laminate with copper foil deposited on its surface. In other embodiments, the limiting plate 20 is fixedly connected to the sub-circuit board 32 and the main circuit board 31 by adhesive.

[0027] In some embodiments, combined with Figure 1 and Figure 2 As shown, the limiting plate 20 is located inside the electrical cavity 13, and there are at least two spring clips 33 that are parallel to each other. The limiting plate 20 is inserted into the gap between adjacent spring clips 33, and the outer edge of the limiting plate 20 is the limiting surface 201. When the plug 91 of the light sign 90 is inserted into the spring clip 33, the limiting surface 201 and the plug 91 are in contact with each other. By inserting a limiting plate 20 between adjacent spring clips 33, the limiting plate 20 can restrict the range of motion of the plug 91 of the light sign 90 after it is inserted into the spring clip 33. Therefore, the spring clips 33 will not easily deform significantly due to large shaking of the light sign 90, thus avoiding large-scale permanent deformation of the spring clips 33 and reducing the probability of poor contact.

[0028] In some embodiments, combined with Figure 1 and Figure 2 As shown, in the insertion direction A, the height of the limiting plate 20 is not less than the height of the spring clip 33, so as to ensure that the part of the plug 91 inserted into the spring clip 33 can be correspondingly limited by the limiting plate 20. Moreover, the outer corner of the limiting surface 201 of the limiting plate 20 is set as a transition arc surface 202. During the process of the plug 91 of the light sign 90 being inserted into the spring clip 33, the transition arc surface 202 plays the role of guiding the plug 91 into the spring clip 33.

[0029] In some embodiments, combined with Figure 1 and Figure 2As shown, the battery box includes a front shell 11 and a rear shell 12 that are fixedly connected to each other. Specifically, the front shell 11 and the rear shell 12 can be detachably fixedly connected by snap-fit. The main circuit board 31 and the sub-circuit board 32 are both disposed in the cavity formed between the front shell 11 and the rear shell 12. In addition, two positioning plates 121 and two positioning posts 122 are provided on the inner wall of the rear shell 12. The main circuit board 31 is respectively provided with strip-shaped positioning holes 311 and positioning round holes 312. The positioning plates 121 are inserted into the strip-shaped positioning holes 311 one by one, and the positioning posts 122 are inserted into the positioning round holes 312 one by one, thereby fixing the position of the main circuit board 31 in the battery box.

[0030] In some embodiments, such as Figure 2 As shown, the upper part of the front shell 11 is provided with a receiving compartment 110, and the electrical connection cavity 13 is the inner cavity of the receiving compartment 110 of the front shell 11. According to the previous description, since the sub-circuit board 32 is fixed in the guide groove 111, when the plug 91 of the light sign 90 is inserted into / pulled out of the spring clip 33, the force of the plug 91 on the sub-circuit board 32 is transmitted to the guide groove 111. That is, the front shell 11 bears the force of the plug 91. Therefore, when the plug 91 is inserted into the spring clip 33, the main circuit board 31 will not be subjected to the force transmitted from the sub-circuit board 32. There is no interaction force between the sub-circuit board 32 and the main circuit board 31. There is no stress in the connection between the limiting plate 20 and the main circuit board 31 and the sub-circuit board 32, and the connection will not be damaged.

[0031] In some embodiments, such as Figure 3 As shown, a horizontal bar 123 is also provided on the inner wall of the rear shell 12. The horizontal bar 123 abuts against the back of one end of the main circuit board 31 connecting to the sub-circuit board 32, while the other end of the sub-circuit board 32 abuts against the inner wall of the receiving compartment 110. When the spring clip 33 is under force, it can prevent the sub-circuit board 32 and the upper part of the main circuit board 31 from being under force and causing horizontal displacement. In addition, one end of the main circuit board 31 connecting to the sub-circuit board 32 abuts against the upper edge 130 of the inner wall of the electrical cavity 13 of the front shell 11. The main circuit board 31 is restricted by the two positioning plates 121, the two positioning posts 122 and the upper edge 130 of the inner wall of the electrical cavity 13, so the main circuit board 31 in the battery box is completely fixed. Moreover, the sub-circuit board 32 is fixed by the guide groove 111, so when the plug 91 of the light sign 90 is inserted into / pulled out of the spring clip 33, the connection between the limiting plate 20 and the main circuit board 31 and the sub-circuit board 32 will not be under force, and there will be no situation of breakage or detachment due to force.

[0032] In some embodiments, such as Figure 3 As shown, the plug 91 of the light sign 90 is inserted into the spring clip 33 in the electrical connection cavity 13. At this time, the spring clip 33 clamps the plug 91 of the light sign 90, and the spring clip 33 contacts the copper contacts 911 of the plug 91 to form an electrical connection. Figure 3As shown, a built-in power supply 14 is provided between the front shell 11 and the rear shell 12. The built-in power supply 14 can be a lithium battery. The built-in power supply 14 is electrically connected to the main circuit board 31 through a power cable, and the main circuit board 31 is electrically connected to the spring clip 33. Therefore, the built-in power supply 14 can provide power to the plugged-in light sign 90. Figure 1 As shown, the main circuit board 31 is also provided with a charging port 313, which is used to charge the built-in power supply 14. The charging port 313 adopts a USB Type-C interface.

[0033] In some embodiments, such as Figure 3 As shown, the main circuit board 31 has a switch button 34 on the side facing the rear shell 12, and the rear shell 12 has a corresponding button through hole 125 for the keycap 35 of the switch button 34 to pass through. The switch button 34 is used to control the voltage on and off of the spring clip 33, that is, to control the power supply of the light sign 90.

[0034] In some embodiments, such as Figure 4 As shown, the front shell 11 of the battery compartment has a support surface 113 for attaching the light sign 90. A double-sided adhesive layer (not shown) can be optionally provided on the support surface 113, which can be used to adhesively fix the soft pad 92 on the back of the light sign 90. A ramp 114 is provided between the insertion port 131 of the electrical connection cavity and the support surface 113. The soft pad 91 on the back of the light sign 90 has a clearance recess 921 at the position corresponding to the plug 91, which is used to make way for the ramp 114 and the receiving compartment 110. The soft pad 92 on the back of the light sign 90 is made of sponge. When the plug 91 of the light sign 90 is inserted into the spring clip, the ramp 114 presses against the bottom surface of the relief recess 921. The force exerted by the ramp 114 on the light sign 90 eventually becomes the pressure exerted by the plug 91 of the light sign 90 on the spring clip, causing the spring clip to generate a reverse force on the plug 91. Therefore, the mutual pressing force between the plug 91 of the light sign 90 and the spring clip is increased, enhancing the stability of the insertion.

[0035] In some embodiments, such as Figure 5As shown, a protrusion 314 is provided at one end where the main circuit board 31 connects to the sub-circuit board 32. The sub-circuit board 32 has a corresponding slot 321 for the protrusion 314, and the protrusion 314 is inserted into the slot 321 to form a snap-fit. Two first copper foils 315 are provided on the main circuit board 31 near the slot 321, and the two first copper foils 315 serve as the positive and negative terminals for voltage output, respectively. The sub-circuit board 32 has two second copper foils 320, which are soldered one-to-one with the spring clips 33. The second copper foils 320 extend to the slot 321, and the first copper foils 315 and second copper foils 320 are soldered one-to-one, thus realizing the electrical connection between the main circuit board 31 and the spring clips 33. In specific implementation, both the main circuit board 31 and the sub-circuit board 32 use copper-clad laminates with copper foil deposited on their surface, and the copper foil wiring of the copper-clad laminate is a conventional technical method.
