Technical Field
[0001] This utility model relates to the field of charger technology, and more specifically, to a charger with a digital display. Background Technology
[0002] With the development of technology and the widespread use of smartphones, mobile phones, as information communication tools, have become an integral part of our lives. As electronic accessories, mobile phone chargers are indispensable; a phone cannot charge or function properly without a charger. Currently, there are many types of chargers on the market. To enhance product competitiveness, some brands even equip their products with digital displays, allowing consumers to monitor the charging voltage and current at any time.
[0003] For example, Chinese patent CN219811991U discloses a novel charger, including a housing, circuit board, pins, and a digital display mechanism. The digital display mechanism includes a display frame and several LED beads. The display frame covers the LED beads and has several display holes arranged in at least two digit shapes. Each LED bead is mounted on the circuit board, with each display hole corresponding to one LED bead. By controlling the different LED beads to be turned on, a digital display structure is formed. This utility model directly mounts LEDs and a display frame on the circuit board. The display frame has light-transmitting display holes in the shape of numbers. By controlling different LEDs to light up, a display effect similar to a digital tube can be produced. However, the display and the circuit board are installed by fitting fixing pins and fixing holes together. Since the display is a small component, it is difficult to install the fixing pins and fixing holes one by one during assembly. The assembly process is cumbersome and prone to defects. Furthermore, the circuit board heats up during charging. If the display and the circuit board are too close together, it will affect the stability of the display, accelerate the aging of the display, and make it prone to failure. Utility Model Content

Furthermore, the support plate and isolation plate work together to ensure the digital display screen and circuit board are installed at an interval, guaranteeing stable operation and extending the product's lifespan.
[0024] The present invention will be further described and illustrated below with reference to specific embodiments and the accompanying drawings:
[0025] refer to Figures 1 to 5 A charger with a digital display includes a housing 10, a circuit board 20, a digital display component 30, a plug component 40, a support plate 50, a top cover 60, and a bottom cover 70. The circuit board 20, the digital display component 30, the plug component 40, and the support plate 50 are disposed in the inner cavity of the housing 10. The top cover 60 and the bottom cover 70 are respectively snapped onto both ends of the housing 10. The plug component 40 is rotatably folded onto the bottom cover 70. In this embodiment, the part of the top cover 60 corresponding to the digital display component 30 is made of transparent material so that the display information of the digital display component 30 can be clearly seen through the transparent top cover 60.
[0026] In another embodiment, a window can be opened on the outer casing 10 to also view the displayed information.
[0027] The digital display component 30 includes an isolation plate 31 and a digital display screen 32. The isolation plate 31 is provided with a mounting groove 314, and the digital display screen 32 is disposed on the mounting groove 314 of the isolation plate 31. The digital display screen 32 of this application has the function of displaying charging voltage and current, and can be equipped with different functions according to market demand. For example, if a temperature sensing device is provided inside the housing 10, the charging temperature can be displayed in real time through the digital display screen 32.
[0028] The isolation plate 31 has a top clamping plate 311 and a fixing clamp 312 on one side. The circuit board 20 is located at the lower end of the top clamping plate 311 and connected to the support plate 50. A slot 313 is formed between the top clamping plate 311 and the fixing clamp 312. One side of the support plate 50 is installed into the slot 313 to form a snap-fit connection. The width of the slot 313 is consistent with the thickness of the support plate 50, ensuring that the support plate 50 can be firmly connected to the isolation plate 31.
[0029] The outer shell 10 is provided with a limiting baffle 11, a slot 12, a limiting block 13 and a buffer block 14. The limiting baffle 11 is located at the end where the outer shell 10 is installed with the top cover 60. The limiting baffle 11 is arranged around the inner side of the outer shell 10. When the support plate 50 is engaged in the slot 313, the limiting baffle 11 is located above the fixing clamp 312. When the support plate 50 and the isolation plate 31 are engaged, the limiting baffle 11 can constrain the isolation plate 31 from above to prevent it from moving upward or loosening during assembly or use.
[0030] The support plate 50 is provided with a connecting part 51 and a pressing part 52. The support plate 50 is engaged with the slot through the connecting parts 51 on both sides. The pressing parts 52 on both sides of the support plate 50 abut against the limiting baffle and the bottom cover respectively.
[0031] The slots 12 are provided on both sides of the inner wall of the outer shell 10. The connecting parts 51 of the support plate 50 are snapped into the slots 12. During assembly, it is only necessary to align the connecting parts 51 on both sides of the support plate 50 with the slots 12 and insert them to complete the fixation. There is no need for complicated alignment or fastening operations, which effectively reduces assembly time and labor costs and improves production efficiency.
[0032] Limiting blocks 13 are provided on both sides of the slot 12. One end of the limiting block 13 abuts against the limiting baffle 11, and the other end of the limiting block 13 is provided with a ramp surface 131. The width gap of the end of the slot 12 with the ramp surface 131 is greater than the width gap of the other end. During assembly, the support plate 50 extends into the slot 12 from the end where the outer shell 10 and the bottom cover 70 are installed. The limiting block 13 is provided with a ramp surface 131, which makes the support plate 50 easier to insert into the slot 12. The ramp surface 131 can guide the support plate 50 to gradually enter the slot 12, reducing the resistance during insertion and making the assembly process easier. The limiting block 13 can provide double restraint on the support plate 50 from the side and the limiting baffle 11, preventing the support plate 50 from moving excessively or loosening in the slot 12, and enhancing the stability of the structure.
[0033] The inner side of the limiting baffle 11 is provided with a buffer block 14. The buffer block 14 is located on one side of the limiting block 13 and abuts against the clamping part 52 of the support plate 50. It can prevent the support plate 50 from being over-installed and play a certain buffering role. The inner side of the bottom cover 70 is provided with an abutting block 71. When the connecting part 51 of the support plate 50 is installed into the slot 12 of the outer shell 10, after the bottom cover 70 and the outer shell 10 are respectively snapped into place with the two ends of the outer shell 10, the clamping part 52 of one end of the support plate 50 abuts against the buffer block 14, and the clamping part 52 of the other end of the support plate 50 abuts against the abutting block 71. This allows the support plate 50 to be firmly fixed in place after being installed into the outer shell 10, ensuring the stability of the overall structure and improving the reliability and service life of the assembly.
[0034] The circuit board 20 is provided with a USB interface 21 and a Type-C interface 22. The top cover 60 is provided with an interface slot 61 that matches the USB interface 21 and the Type-C interface 22. Different device interfaces can be set according to user needs. The circuit board 20 is provided with multiple different interfaces, which can meet the needs of connecting different devices for charging, providing users with a better user experience.
[0035] The support plate 50 is provided with a limiting groove 53 on one side that cooperates with the slot 313. The length of the limiting groove 53 is consistent with the width of the isolation plate 31. When the isolation plate 31 is engaged with the limiting groove 53 of the support plate 50 through the slot 313, the isolation plate 31 is limited in the limiting groove 53. The isolation plate 31 cannot slide laterally on the limiting groove 53 relative to the support plate 50, which makes the overall structure more stable.
[0036] In this embodiment, the top clamping plate 311 is a right-angled triangle. The top clamping plate 311 is provided with an abutment portion 3111 and a support portion 3112. The abutment portion 3111 and the support portion 3112 are the two right-angled sides of the right triangle. The abutment portion 3111 abuts against the support plate 50, and the support portion 3112 is fixedly connected to the bottom of the isolation plate 31 to provide support. The triangle has a stable state, which allows the isolation plate 31 to be firmly installed in the outer shell 10 and effectively prevents the isolation plate 31 from rotating relative to the support plate 50.
[0037] In another embodiment, both sides of the isolation plate 31 are provided with a top clamping plate 311 and a fixing clamp 312. The grooves 313 formed by the top clamping plate 311 and the fixing clamp 312 of the isolation plate 31 are each fitted with a support plate 50. The support plate 50 supports the digital display component 30 at the same time. The double-sided design makes the connection of the isolation plate 31 more symmetrical and the force more even, further enhancing the stability of the overall structure. The adjacent top clamping plate 311 and the fixing clamp 312 can be stretched together into a whole, which can play a better limiting effect on the support plate 50.
[0038] The digital display screen 32 has a protective cotton 33 on its top and a heat insulation cotton 34 on its bottom. The protective cotton 33, the digital display screen 32 and the heat insulation cotton 34 are stacked in the mounting groove 314.
[0039] Among them, the protective cotton 33 has a cushioning effect, which can reduce the damage to the digital display screen 32 during installation or use; the normal operating temperature of the digital display screen 32 is generally between -20℃ and 70℃. When the charger is charging, the temperature of the circuit board 20 is too high, which will affect the normal operation of the digital display screen 32 and easily accelerate aging. The heat insulation cotton 34 is placed between the digital display screen 32 and the circuit board 20 to effectively isolate the heat generated by the circuit board 20 during charging, ensuring that the digital display screen 32 works in a stable environment and extending its service life.
[0040] The plug assembly 40 includes a folding plug 41, a flexible contact 42, and a mounting base 43. The mounting base 43 is screwed onto the bottom cover 70. The folding plug 41 is rotatably disposed between the mounting base 43 and the bottom cover 70. One end of the flexible contact 42 abuts against the tail end of the folding plug 41, and the other end is electrically connected to the circuit board 20. When the charger is not in use, the folding plug 41 can be folded up and stored inside the bottom cover 70, reducing space occupation and making it easy to carry and store. The folding plug 41 can be configured to meet different market standards, such as national standards or European standards.
[0041] The assembly method of this application is as follows: First, the digital display screen 32 is fixedly installed in the mounting groove 314 of the isolation plate 31, and one side of the support plate 50 is aligned with the slot 313 on the isolation plate 31, so that the support plate 50 is inserted and engaged in the slot 313. The width of the slot 313 matches the thickness of the support plate 50 to ensure that the support plate 50 can be firmly connected to the isolation plate 31. After the support plate 50 is inserted into the slots 12 on both sides of the inner wall of the outer shell 10 through its connecting part 51, the top cover 60 and the bottom cover 70 are respectively engaged with the two ends of the outer shell 10. The abutting part 52 on one side of the support plate abuts against the buffer block 14 of the limiting baffle 11, and the abutting block 71 of the bottom cover 70 limits and fixes the abutting part 52 on the other side of the support plate 50, so that the overall structure after assembly is stable and the whole assembly process is simple and convenient.
[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
