Abstract
Description
Technical Field
[0001] This utility model relates to the field of digital tube technology, and in particular to a digital tube assembly, a digital tube display screen, and a mobile power supply. Background Technology
[0002] With the continuous development of portable power bank technology, current portable power banks will directly display the power percentage in digital form through digital tube displays, and can also indicate whether fast charging protocols (such as USB-C PD protocol) are supported through indicator lights.
[0003] In existing technologies, the pins of digital tubes are directly mounted onto the circuit board. However, this setup means that the pin height often needs to be customized according to specific project requirements, resulting in poor versatility. For example, one project might use shorter pin lengths to fit a compact circuit layout, while another project might require longer pins to meet heat dissipation or space design requirements. Different pin heights are needed for these two structures, making it impossible to meet both needs with a single type of digital tube. Utility Model Content

[0023] With the continuous development of portable power bank technology, current portable power banks will directly display the power percentage in digital form through digital tube displays, and can also indicate whether fast charging protocols are supported through indicator lights.
[0024] In existing technologies, the pins of digital tubes are directly mounted onto the circuit board. However, this setup means that the pin height often needs to be customized according to specific project requirements, resulting in poor versatility. For example, one project might use shorter pin lengths to fit a compact circuit layout, while another project might require longer pins to meet heat dissipation or space design requirements. Different pin heights are needed for these two structures, making it impossible to meet both needs with a single type of digital tube.
[0025] The main purpose of this utility model is to propose a digital tube assembly 100, a digital tube display screen 200, and a mobile power supply 300, which aims to improve the versatility of the digital tube body 3 and meet the requirements of different projects for the length of the pins 31.
[0026] Please see Figures 3 to 5 In one embodiment of the present invention, the digital tube assembly 100 includes a connecting post 12 and a digital tube body 3. The connecting post 12 is used for electrical connection with the circuit board 1. The digital tube body 3 is provided with pins 31, which are elastically connected to and electrically connected to the side of the connecting post 12 away from the circuit board 1.
[0027] Understandably, by setting up the connecting post 12 and making it elastically connected to the pin 31 of the digital tube body 3, the digital tube body 3 can move up and down relative to the connecting post 12 after being pressed, thus having a certain adjustment range. The connecting post 12 is electrically connected to the digital tube body 3. After the connecting post 12 is electrically connected to the circuit board 1, the distance between the digital tube body 3 and the circuit board 1 can be changed by moving the digital tube body 3, thereby meeting the requirements of different projects for the length of the pin 31.
[0028] In one implementation, please refer to Figure 4 and Figure 5 The connecting post 12 has an insertion slot 121, and the pin 31 is movably inserted into the insertion slot 121. The digital tube assembly 100 also includes an elastic element 2, with its two sides connected to the pin 31 and the bottom of the insertion slot 121, respectively. The digital tube body 3 can move relative to the bottom of the insertion slot 121 by compressing the elastic element 2.
[0029] In this embodiment, by providing an insertion slot 121 on the connecting post 12 and placing the elastic element 2 within the insertion slot 121, the pins 31 of the digital tube body 3 are movably inserted into the insertion slot 121 and connected to the elastic element 2. The pins 31 of the digital tube body 3 compress the elastic element 2, allowing the digital tube body 3 to move up and down within the insertion slot 121. This arrangement, through the elastic action of the elastic element 2, provides the digital tube body 3 with a certain adjustment space within the insertion slot 121, thereby meeting the pin 31 length requirements of different projects.
[0030] It is understood that the pin 31 in this embodiment is made of a rigid material, such as a conductive metal. At this time, the pin 31 can not only play a supporting role, but also transmit the pressure to the elastic element 2 after the digital tube assembly 100 is subjected to pressure, so that the elastic element 2 is compressed.
[0031] Optionally, pin 31 can be directly connected to connecting post 12 via elastic element 2, in which case insertion slot 121 is not provided, and elastic element 2 is conductive. Understandably, in this case, the stability of pin 31 when moving relative to connecting post 12 is poor, and it is prone to lateral swaying.
[0032] In one implementation, please refer to Figure 5 Elastic element 2 is a spring.
[0033] In this embodiment, the elastic element 2 is a spring, and the end face of the spring that contacts the pin 31 forms an annular ring to provide sufficient support area. At the same time, in the initial state, that is, when the digital tube body 3 is not subjected to other pressure, the spring is in a compressed state, and can be further compressed when the digital tube body 3 is subjected to pressure, thereby allowing the digital tube body 3 to move relative to the bottom of the insertion slot 121.
[0034] Understandably, the elastic element 2 is made of metal. In this case, the pin 31 is electrically connected to the bottom of the insertion slot 121 via the elastic element 2, thus ensuring that the digital tube body 3 is electrically connected to the circuit board 1 via the elastic element 2 and the connecting post 12. At this time, both sides of the elastic element 2 can be connected and fixed to the bottom of the insertion slot 121 and the pin 31 respectively, for example, by welding, to ensure the stability of the electrical connection; or, the elastic element 2 can be movably disposed within the insertion slot 121, and the weight of the digital tube body 3 alone can compress the elastic element 2, so that both sides of the elastic element 2 are connected to the bottom of the insertion slot 121 and the pin 31 respectively.
[0035] Optionally, the elastic element 2 can also be a rubber pad. Since the rubber pad is an insulating material, the width of the insertion groove 121 can be adjusted so that when the pin 31 slides in the insertion groove 121, it contacts the side wall of the insertion groove 121, thereby achieving electrical connection.
[0036] In one implementation, please refer to Figure 4 and Figure 5 The pin 31 includes a first segment 311 and a second segment 312 that are connected to each other. The second segment 312 is movably disposed in the insertion slot 121 and is connected to the elastic member 2. When the second segment 312 moves toward the slot opening 122 of the insertion slot 121, it can abut against the slot opening 122 and be limited.
[0037] In this embodiment, pin 31 has a two-segment structure, including a first segment 311 and a second segment 312 connected to each other. The first segment 311 is used to connect with the digital tube body 3, and the second segment 312 is movably disposed in the insertion slot 121 and connected with the elastic member 2. It can be understood that by the contact and limiting of the second segment 312 with the slot 122, the pin 31 can be prevented from moving excessively and detaching from the insertion slot 121.
[0038] Optionally, a stop mechanism can be provided along the circumference of the slot 122 to reduce the size of the slot 122. When the second segment 312 moves into the slot 122, the second segment 312 will abut against the stop mechanism, thereby achieving the limiting function. Specifically, the stop mechanism can be an annular baffle provided in the slot 122, and the first segment 311 is movably inserted through the inner circle of the annular baffle. Optionally, the cross-sectional dimensions of the first segment 311 and the second segment 312 can be the same, with a protrusion only provided on the side wall of the second segment 312, so that the protrusion abuts against the annular baffle for limiting.
[0039] In one implementation, please refer to Figure 4 and Figure 5 Both the first segment 311 and the second segment 312 are cylindrical. The size of the slot 122 is larger than the cross-sectional size of the first segment 311 and smaller than the cross-sectional size of the second segment 312.
[0040] In this embodiment, both the first segment 311 and the second segment 312 are cylindrical, and the cross-sectional diameter of the first segment 311 is smaller than that of the second segment 312. The slot 122 is circular, and its diameter is smaller than that of the second segment 312 but larger than that of the first segment 311. This allows the pin 31 to penetrate deeper into the insertion slot 121, reducing the distance between the digital tube body 3 and the circuit board 1, while preventing the pin 31 from detaching from the insertion slot 121.
[0041] In one implementation, please refer to Figure 4 and Figure 5 The connecting column 12 has a limiting section 124 and a sliding section 123 that are connected to each other. The limiting section 124 and the sliding section 123 cooperate to form an insertion groove 121. A slot 122 is formed on the side of the limiting section 124 away from the sliding section 123. The cross-sectional dimension of the insertion groove 121 relative to the sliding section 123 is not less than the cross-sectional dimension of the second section 312.
[0042] In this embodiment, during the manufacturing process, the connecting column 12 initially has a cylindrical insertion groove 121. At this time, the cross-sectional dimension of the insertion groove 121 is not less than the cross-sectional dimension of the second segment 312, so that the elastic member 2 and the second segment 312 can be placed into the insertion groove 121. Then, the groove opening 122 of the insertion groove 121 is rolled to reduce the size of the groove opening 122, so that the second segment 312 is confined within the insertion groove 121.
[0043] Understandably, at this time, a limiting segment 124 is formed on the side of the connecting column 12 near the slot 122, that is, the limiting segment 124 has been rolled, and the second segment 312 can slide in the sliding segment 123 that has not been rolled.
[0044] In one implementation, please refer to Figure 3 and Figure 5 The digital tube assembly 100 also includes a mounting bracket 13, which is disposed on the circuit board 1. The mounting bracket 13 has a movable slot 131 and a connecting hole 132. The connecting hole 132 communicates with the movable slot 131 and is correspondingly disposed with the connecting post 12. The digital tube body 3 is movably disposed in the movable slot 131, and the pin 31 passes through the connecting hole 132 and is elastically and electrically connected to the connecting post 12.
[0045] Understandably, by setting up the mounting bracket 13, the digital tube body 3 is movably installed in the movable slot 131 of the mounting bracket 13. The side wall of the movable slot 131 plays a limiting and guiding role, so that the digital tube body 3 will only move in the vertical direction after being subjected to pressure, and will not shift laterally. In addition, the bottom of the movable slot 131 is provided with a connecting hole 132, through which the pin 31 passes and is inserted into the insertion slot 121.
[0046] Optionally, the mounting bracket 13 can be made of insulating material to prevent short circuits. Meanwhile, the size of the movable slot 131 can be adjusted according to the actual size of the digital tube body 3 to ensure stable installation within the movable slot 131.
[0047] In one implementation, please refer to Figure 3 and Figure 5 The pins 31 include multiple pins, and each pin 31 is elastically connected to and electrically connected to the connecting post 12.
[0048] In this embodiment, the digital tube assembly 100 includes multiple pins 31, insertion slots 121 and elastic elements 2. Each insertion slot 121 corresponds to an elastic element 2 and a pin 31. Each pin 31 can be adjusted independently, thereby ensuring the stability of the electrical connection between the digital tube body 3 and the connecting post 12.
[0049] In one implementation, please refer to Figure 5 Multiple pins 31 are arranged sequentially along the length of the digital tube body 3.
[0050] In this embodiment, multiple pins 31 are arranged sequentially along the length of the digital tube body 3, so that the pins 31 can be evenly distributed. At the same time, the spacing of the pins 31 can be adjusted according to the size of the digital tube body 3 and the electrical connection requirements.
[0051] In the prior art, a lens 202 is usually disposed above the display surface 32 of the digital tube body 3 to transmit light and display values, thereby enhancing the display effect and protecting the digital tube body 3. To ensure the clarity of the display, the lens 202 and the digital tube body 3 are usually subjected to an interference fit. This method causes the digital tube body 3 to apply an upward force to the lens 202 to ensure a tight fit between the display surface 32 and the lens 202.
[0052] However, over time, the continuous force exerted by the digital tube body 3 on the lens 202 can cause the lens 202 to warp. Simultaneously, because the digital tube body 3 is fixedly connected to the circuit board 1, a gap can easily appear between the lens 202 and the display surface 32, resulting in the digital tube body 3 displaying values on the lens 202 unclearly, thus affecting the user experience.
[0053] To resolve the above issues, please refer to Figure 1 and Figure 2The present invention also proposes a digital tube display screen 200, which includes a housing 201, a lens 202 and a digital tube assembly 100. The specific structure of the digital tube assembly 100 is as described in the above embodiments. Since the digital tube display screen 200 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
[0054] The housing 201 has a cavity 2011 and a display hole 2012, which are connected to the cavity 2011. The digital tube assembly 100 is disposed in the cavity 2011, the digital tube body 3 is located in the display hole 2012, and the display surface 32 of the digital tube body 3 faces away from the cavity 2011. The lens 202 is disposed in the housing 201 and abuts against the display surface 32.
[0055] Understandably, during installation, the digital tube assembly 100 is first installed inside the cavity 2011. Initially, the digital tube body 3 is located inside the display hole 2012, and the display surface 32 protrudes from the surface of the housing 201. Then, the lens 202 is adhered to the surface of the housing 201 using double-sided adhesive 203 to cover the display surface 32. Because the display surface 32 protrudes from the surface of the housing 201, adhering the lens 202 to the surface of the housing 201 exerts a squeezing effect on the digital tube body 3, compressing the elastic element 2. The digital tube body 3 moves along the insertion slot 121, at which point the display surface 32 and the lens 202 are tightly fitted. Over time, the lens 202 may slightly warp due to environmental factors or long-term use, reducing its pressure on the digital tube body 3. At this time, the elastic element 2 releases its previously stored elastic potential energy, gradually restoring its length and pushing the digital tube body 3 upwards, causing the display surface 32 to once again tightly fit with the lens 202. The elastic element 2 thus ensures a tight fit between the display surface 32 and the lens 202, thereby maintaining the clarity of the numerical display over a long period of time.
[0056] Please see Figure 1 This utility model also proposes a portable power bank 300, which includes a digital tube display screen 200. The specific structure of the digital tube display screen 200 is as described in the above embodiments. Since this portable power bank 300 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here.
[0057] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
