Technical Field

[0001] This application relates to the field of portable device technology, and more particularly to a button structure and a portable device. Background Technology

[0002] The top cover of the portable mobile energy storage device has good sealing performance and is not easy to leak water. However, the button structure on the top of the portable mobile energy storage device is prone to water leakage because it needs to be operated by pressing the buttons. This can damage the performance of internal electrical components and even affect the normal operation of the device, thus affecting the user's outdoor experience.

[0003] Therefore, how to prevent water from seeping into the button structure of portable devices is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0037] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, 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, 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.

[0038] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, various specific examples of processes and materials are provided in this application; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0039] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0040] See Figure 2 This application provides a button structure, including a shell plate 100 and a button assembly. The shell plate 100 has at least one button hole 102. The button assembly includes a flexible waterproof component 200 and at least one pressing component 201. The flexible waterproof component 200 is disposed on the pressing component 201, and the pressing component 201 corresponds to the button hole 102. The pressing component 201 can be pressed through the button hole 102. The flexible waterproof component 200 is in contact with the shell plate 100. At least one first drainage groove 108 is provided on the side of the shell plate 100 near the flexible waterproof component 200. The first end of the first drainage groove 108 is connected to the button hole 102, and the second end of the first drainage groove 108 is connected to the edge of the shell plate 100.

[0041] Specifically, when there is only one button hole 102, only one first drainage groove 108 needs to be set. When there are two or more button holes 102, the number of first drainage grooves 108 can be the same as the number of button holes 102, and one first drainage groove 108 is set for each button hole 102.

[0042] Specifically, the shell plate 100 and the groove 101 described below are preferably integrally molded, and their materials include, but are not limited to, plastic, stainless steel, aluminum alloy or steel plate.

[0043] Specifically, initially, the first drainage groove 108 is an open groove. When the flexible waterproof component 200 is attached to the groove 101, the flexible waterproof component 200 closes part of the first drainage groove 108, making the first drainage groove 108 a drainage channel with both ends connected for the drainage of accumulated water.

[0044] It should be noted that, under normal circumstances, the thickness of the flexible waterproof component 200 is relatively small, making it impossible to design a drainage groove. If the thickness of the flexible waterproof component 200 is increased in order to set up a drainage groove, it will affect the button performance and button feel, and at the same time increase the material cost and mold cost of the flexible waterproof component 200. Therefore, this application preferably provides a first drainage groove 108 on the groove 101 of the shell plate 100 to satisfy the drainage function without affecting the button operation, thus ensuring the stability and accuracy of the button.

[0045] Furthermore, to enhance drainage, a slight inclination or curvature can be provided at the bottom of the first drainage channel 108, allowing accumulated water to flow more smoothly to the edge of the shell plate 100. In addition, to prevent dust and debris from entering the first drainage channel 108, a dustproof pad can be provided at the button hole 102.

[0046] In the button structure provided by this utility model, when in use, the first drainage groove 108 is formed on the shell plate 100, and the flexible waterproof component 200 is attached to the shell plate 100 to form a semi-sealed first drainage groove 108. When there is water accumulation in the button hole 102, the water flows from the button hole 102 through the first drainage groove 108 to the edge of the shell plate 100 and is discharged between the shell plate 100 and the flexible waterproof component 200. This arrangement can drain the accumulated water in time, thereby preventing water from seeping into the button structure of the portable device, avoiding water seepage from the button structure and damaging the internal electrical components of the portable device, and also avoiding the need to set a groove on the flexible waterproof component 200, which would affect the other overall performance of the flexible waterproof component 200.

[0047] See Figure 5To optimize the above technical solution, the flexible waterproof component 200 includes a pressing protrusion 202 and a connecting part. The pressing protrusion 202 corresponds one-to-one with the pressing component 201. The pressing protrusion 202 is connected to the connecting part, and the pressing protrusion 202 protrudes from the connecting part. The pressing protrusion 202 can extend and retract along the axial direction of the button hole 102 inside the button hole 102. The pressing protrusion 202 is connected to the pressing component 201.

[0048] Specifically, in some embodiments, the connecting portion is a groove.

[0049] Specifically, the flexible waterproof component 200 is made of elastic material, preferably silicone material, the pressing component 201 is made of plastic material, the pressing protrusion 202 and the groove are integrally formed in the flexible waterproof component 200, and the groove is preferably a U-shaped groove 204.

[0050] Specifically, the pressing protrusion 202 and the pressing element 201 are tightly connected by adhesive.

[0051] Specifically, the groove design increases the flexibility and durability of the button. When the button is pressed, the pressing part 201 and the pressing protrusion 202 can jointly bear the pressure and absorb part of the impact force through the deformation of the groove, and generate a rebound force and support force in the vertical direction. This makes the pressing part 201 rebound more powerfully, smoothly and steadily, and less prone to sticking, thus improving the button's response speed and comfort.

[0052] In use, when water seeps into the flexible waterproof component 200 from the gaps around the pressing component 201, the water will be drained out of the shell plate 100 under the guidance of the groove and the first drainage channel 108. It should be noted that the operator can change the connection position of the second end of the first drainage channel 108 according to the needs of use. For example, it can be directly connected to the outside of the portable device or connected to the inside of the shell plate 100, as long as the water in the button structure can be drained. Since the water ingress of the button structure is usually small, this application preferably connects the second end of the first drainage channel 108 to the inside of the shell plate 100. A small amount of water will evaporate quickly in the accommodating space of the shell plate 100. The groove can serve as an additional drainage channel to deal with the situation of a large amount of water. Therefore, this application can drain the water in time, thereby preventing water from seeping into the button structure of the portable device.

[0053] Furthermore, the shell plate 100 has a first surface and a second surface that are arranged opposite to each other. A groove 101 is provided on the first surface of the shell plate 100. The second surface of the shell plate 100 is fitted and connected to the flexible waterproof component 200. At least one key hole 102 is provided at the bottom of the groove 101. A first drainage groove 108 is opened on the second surface of the shell plate 100 and is located at the bottom of the groove 101.

[0054] See Figure 3To optimize the above technical solution, the system also includes a button frame plate 300 and reinforcing ribs. The button frame plate 300 has a through hole in the middle. A flexible waterproof component 200 covers the through hole and is connected to the button frame plate 300. The connecting end of the reinforcing rib is connected to the hole wall of the through hole. The reinforcing rib and the hole wall of the through hole form a first limiting hole, and / or the reinforcing rib surrounds a second limiting hole. The first limiting hole and / or the second limiting hole correspond one-to-one with the pressing component 201, so that the pressing component 201 can move along the axial direction of the limiting hole.

[0055] Specifically, when the reinforcing rib is straight, if there is one straight reinforcing rib, the through hole will be divided into two first limiting holes. Similarly, when there are two straight reinforcing ribs, the two intersecting straight reinforcing ribs will divide the through hole into four first limiting holes, and the two non-intersecting straight reinforcing ribs will divide the through hole into three first limiting holes. When there are three or more straight reinforcing ribs, at least one second limiting hole will appear. Therefore, the shape, number and arrangement of the reinforcing ribs will divide the through hole into first limiting holes and / or second limiting holes with different shapes, numbers and arrangements. The first limiting holes and / or second limiting holes correspond one-to-one with the pressing part 201.

[0056] Specifically, when the overall edge shape of the reinforcing rib is the same as the overall wall shape of the through hole, for example, when the reinforcing rib is square and the inside of the square is connected with horizontal or vertical ribs, and the edge of the square can also be connected to the overall wall of the through hole, the second limiting hole is only arranged on the reinforcing rib body, and the reinforcing rib body and the through hole will not form the first limiting hole.

[0057] Specifically, when the reinforcing rib is circular in the middle and connected to a straight rib on each side of the circular middle, the circular middle body forms a second limiting hole, and the two straight ribs are connected to the hole wall of the through hole, forming two first limiting holes with the hole wall of the through hole.

[0058] Therefore, the number, shape, and arrangement of the first and second limiting holes can vary in many ways, which will not be elaborated here.

[0059] Furthermore, the reinforcing rib includes a first reinforcing rib 301 and at least one second reinforcing rib 302. The extending direction of the first reinforcing rib 301 and the extending direction of the second reinforcing rib 302 are perpendicular to each other in the horizontal plane. The limiting hole formed by the first reinforcing rib 301, the second reinforcing rib 302 and the hole wall corresponds to the pressing member 201.

[0060] Specifically, as described above, when there is one first reinforcing rib 301 and two second reinforcing ribs 302, and the first reinforcing rib 301 and the second reinforcing rib 302 are straight, and the extension direction of the first reinforcing rib 301 and the extension direction of the second reinforcing rib 302 are perpendicular to each other in the horizontal plane, the first reinforcing rib 301 and the second reinforcing rib 302 together divide the through hole into six first limiting holes.

[0061] Specifically, the first reinforcing rib 301 and the second reinforcing rib 302 can together form a square limiting hole.

[0062] Specifically, the through hole is located below the area where the pressing protrusion 202 is located. It is used to accommodate the pressing protrusion 202 when pressed downwards and provides space for installing the button mold post 203 described below.

[0063] Specifically, the reinforcing rib can be any support rib connected to the wall of the through hole at both ends. In this case, the reinforcing rib only serves to strengthen the support capacity of the button frame plate 300. If the reinforcing rib is designed as the first reinforcing rib 301 and the second reinforcing rib 302, it can strengthen the support capacity of the button frame plate 300 on the one hand, and support the edge of the pressing protrusion 202 on the other hand, so that the force is even when the button is pressed and it is not easy to tilt or misalign.

[0064] Specifically, the bottom of the flexible waterproof component 200 is connected to the button frame plate 300 via a positioning post. The first reinforcing rib 301 and the second reinforcing rib 302 are used to support the pressing protrusion 202 and the pressing component 201. The bottom of the flexible waterproof component 200 also includes a button mold post 203, which is connected to the bottom of the pressing component 201 and is connected to the electronic control board 401 of the portable device. It is arranged in the limiting hole. At the same time, the positioning post can assist in the accurate connection between the button mold post 203 and the electronic control board 401.

[0065] When in use, the operator presses down on the pressing part 201, and the pressing protrusion 202 produces elastic deformation, which acts on the edge of the first limiting hole or the second limiting hole, so that the button is pressed evenly and is not easy to tilt or misalign. In addition, the groove makes the pressing part 201 rebound stably and powerfully, thereby improving the button performance and pressing feel of the portable device.

[0066] By arranging the first reinforcing rib 301 and the second reinforcing rib 302, the stability of the key frame plate 300 is enhanced, and the pressing protrusion 202 can be accurately installed in the predetermined position. When the key is pressed, the first reinforcing rib 301 and the second reinforcing rib 302 can provide additional support for the key, while preventing the key frame plate 300 from deforming or being damaged.

[0067] Furthermore, the upper surface of the pressing member 201 can be set as a concave curved surface to prevent the pressing member 201 from tilting when it is pressed, thereby further improving the comfort of pressing.

[0068] To optimize the above technical solution, there are multiple button holes 102, and each button hole 102 is connected to a first drainage groove 108. The number of first drainage grooves 108 is the same as the number of button holes 102.

[0069] Specifically, in this design, each button hole 102 has independent drainage, ensuring that each button hole 102 has a corresponding first drainage groove 108 to drain accumulated water. When water seeps into multiple button holes 102 simultaneously, the water around each button hole 102 will be quickly drained along the corresponding first drainage groove 108, preventing water from lingering and spreading in the button structure.

[0070] This arrangement improves drainage efficiency, ensuring that each of the 102 button holes receives timely and effective drainage. It also reduces the risk of damage to electrical components due to water accumulation, extending the lifespan of the portable device.

[0071] Furthermore, for the frequently used button hole 102, the depth and width of the first drainage groove 108 can be increased to improve its drainage capacity.

[0072] To optimize the above technical solution, at least one second drainage groove 109 is provided on the side of the shell plate 100 near the flexible waterproof component 200, and there are multiple button holes 102. The two ends of the second drainage groove 109 are respectively connected to two button holes 102.

[0073] Specifically, the second drainage channel 109 is provided to connect the button hole 102, concentrate the drainage path, and reduce the number of first drainage channels 108.

[0074] When there are two button holes 102, there are two drainage schemes. One is to set two first drainage channels 108, and the two first drainage channels 108 are respectively connected to the two button holes 102, so that the two button holes 102 drain independently. The other is to set one first drainage channel 108 and one second drainage channel 109. The first drainage channel 108 is connected to any one of the button holes 102, and the second drainage channel 109 is connected between the two button holes 102, so that the two button holes 102 achieve coordinated drainage.

[0075] See Figure 1 and Figure 8For example, when the button hole 102 includes a first hole 1021, a second hole 1022, a third hole 1023, and a fourth hole 1024, and the second hole 1022 and the third hole 1023 are vertically distributed and parallel to the first hole 1021, and the fourth hole 1024 is located away from and parallel to the first hole 1021, and the first hole 1021 is large in size, while the second hole 1022, the third hole 1023, and the fourth hole 1024 are small in size, two first drainage grooves 108 can be provided, namely a first sub-drainage groove 103 and a second sub-drainage groove 104. The first end of the first sub-drainage groove 103 is connected to the first hole 1021, and the second end is connected to the edge of the groove 101. The first end of the second sub-drainage groove 104 is connected to the fourth hole 1021. 24. The second end connects to the edge of the groove 101. The second ends of the first sub-drainage channel 103 and the second sub-drainage channel 104 converge. At the same time, three second drainage channels 109 are provided, namely the third sub-drainage channel 105, the fourth sub-drainage channel 106 and the fifth sub-drainage channel 107. The third sub-drainage channel 105 is used to connect the second hole 1022 and the first sub-drainage channel 103. The fourth sub-drainage channel 106 is used to connect the first hole 1021 and the third hole 1023. The fifth sub-drainage channel 107 is used to connect the third hole 1023 and the second sub-drainage channel 104. This arrangement makes the first hole 1021 include two drainage paths and simplifies the drainage paths of the second hole 1022, the third hole 1023 and the fourth hole 1024, so that the accumulated water can be discharged quickly.

[0076] In the above embodiments, the first hole 1021 is relatively large and accumulates a large amount of water. Therefore, a first sub-drainage channel 103 and a fourth sub-drainage channel 106 are provided to form two drainage paths. Simultaneously, water accumulated in the third hole 1023 can flow into the second sub-drainage channel 104 via the fifth sub-drainage channel 107 to prevent water from entering the fourth hole 1024. Drainage from the second hole 1022 is achieved through the third sub-drainage channel 105, with water in the third sub-drainage channel 105 flowing into the first sub-drainage channel 103. This design reduces the area occupied by the third sub-drainage channel 105 while simultaneously satisfying the independent drainage of the second hole 1022. The above-described layout scheme of the first drainage channel 108 and the second drainage channel 109 is only a specific embodiment where the number of button holes 102 is four and the size of the button holes 102 varies. Depending on the arrangement, number, and size of the button holes 102, operators can flexibly design the paths of the first drainage channel 108 and the second drainage channel 109 to meet various drainage needs.

[0077] By arranging the second drainage channel 109, the number and flexibility of drainage channels are increased. When there is a lot of water around one of the button holes 102, the water can be diverted to the drainage area near the other button hole 102 through the second drainage channel 109 for discharge. This ensures that the water can be discharged quickly from multiple directions, reducing the risk of damage to electrical parts caused by water accumulation and improving the stability and durability of the equipment.

[0078] See Figure 7 This application embodiment also provides a portable device, including a device body 400, an electronic control board 401, and a button structure as described above. The button structure is disposed on the device body 400, the shell plate 100 of the button structure is connected to the shell of the device body 400, and the pressing member 201 of the button structure is connected to the electronic control board 401 for point contact. The pressing member 201 is used to press the electronic control board 401 and control the electronic control board 401 to issue a preset command.

[0079] Among them, portable devices can be portable power banks, portable refrigerators, or portable air conditioners.

[0080] Specifically, when the pressing part 201 touches the preset area of ​​the electronic control board 401, the electronic control board 401 issues a corresponding preset command to control the refrigerator's cooling on, cooling off, heating up, cooling down and other functions.

[0081] Furthermore, in portable devices, the button structure should fit tightly with the electronic control board 401 to ensure the stability and reliability of the overall structure. To achieve this, screws, clips, or other connection methods can be used to fix the shell 100 of the button structure to the electronic control board 401, while a waterproof baffle is placed at the location where the screws are installed.

[0082] See Figure 4 To optimize the above technical solution, the portable device also includes a display component, which is disposed above the electronic control board 401. The display component includes a fixing frame 500 and a display screen 501. The portable device also includes a first sealing member. The fixing frame 500 includes an inner groove, the display screen 501 is snapped into the inside of the inner groove, and the first sealing member is disposed between the display screen 501 and the inner groove.

[0083] Specifically, the first sealing component includes, but is not limited to, waterproof foam strips, sealing strips, waterproof rubber rings, etc. In order to ensure the waterproof performance of the display component, this application prefers the first sealing component to be a waterproof foam strip.

[0084] Specifically, the waterproof foam strip is adhered to the surface of the fixed frame 500 and extends beyond the edge of the display screen 501 by a predetermined distance. It covers and seals the gap between the display screen 501 and the fixed frame 500, so as to buffer and protect the display screen 501 while preventing water from seeping into the electronic control board 401 from the display screen 501.

[0085] This arrangement improves the stability and waterproof performance of the display screen 501, avoiding malfunctions and repair costs caused by loosening or water leakage. At the same time, it enhances the user experience and ensures the clarity and stability of the display screen 501 in outdoor environments.

[0086] To optimize the above technical solution, the portable device also includes a second sealing component 502, which is laid below the display screen 501 and is attached to the side of the display screen 501 facing the electronic control board, i.e., the back of the display screen.

[0087] Specifically, the second sealing element 502 is preferably an EVA foam sheet (ethylene-vinyl acetate copolymer foam sheet).

[0088] In use, when water seeps from the top of the display screen 501 to the second sealing member 502, the second sealing member 502 can further prevent water from continuing to seep into the electronic control board 401 below the display screen 501. At the same time, under certain circumstances, the second sealing member 502 can prevent water from seeping into the display screen 501 from the bottom.

[0089] Furthermore, the second sealing element 502 can also be made of other waterproof materials and is tightly attached to the back of the display screen 501. By arranging the second sealing element 502, the waterproof performance and stability of the display screen 501 are improved, reducing failures and maintenance costs caused by water seepage, while ensuring the long-term stable operation of the display screen 501 in outdoor environments.

[0090] Furthermore, a waterproof lens may be provided on the top of the display screen 501 to prevent water from seeping into the display screen 501 at the top layer, thus providing initial protection for the display screen 501 and improving the waterproof performance of the display components.

[0091] See Figure 6 To optimize the above technical solution, the housing of the device body 400 includes an upper housing 700, a lower housing, and a bottom partition 600. The bottom partition 600 is disposed between the upper housing 700 and the lower housing, and a receiving space is formed between the bottom partition 600 and the upper housing 700. The display component, button structure, and electronic control board 401 are arranged inside the receiving space. The bottom partition 600 is connected to the upper housing 700 and the lower housing respectively. The side of the bottom partition 600 near the upper housing 700 is an inclined surface, and a drain hole 601 is provided at the end of the bottom partition 600 away from the upper housing 700.

[0092] Specifically, a space is formed between the lower housing and the bottom partition 600 to accommodate the power supply, heat dissipation, and other devices of the portable device. The upper housing plate and the aforementioned housing 100 can be an integral structure or a separate structure. When the upper housing plate and housing 100 are separate structures, the upper housing plate is connected to the housing 100. In this application, the upper housing plate and housing 100 are separate structures.

[0093] Specifically, the bottom partition 600 is arranged horizontally and slightly inclined to have a water-guiding slope, and the drain hole 601 is provided at the downward inclined end of the bottom partition 600 to facilitate drainage.

[0094] Specifically, the accommodating space is formed by the upper shell 700 and the bottom partition 600, and preferably the drain hole 601 is located at one corner of the bottom partition 600.

[0095] Specifically, the drain hole 601 is designed to ensure that accumulated water can be quickly drained from the bottom partition 600 to the outside of the portable device or near the casing of the portable device.

[0096] Specifically, the upper housing 700 is screwed to the bottom partition 600. If a large amount of water accumulates at the housing 100, it can be discharged through the drainage hole 601 of the bottom partition 600 to further improve the drainage performance of the portable device.

[0097] By arranging the inclined bottom partition 600 and drainage holes 601, the drainage efficiency and waterproof performance of the equipment are improved, and the stagnation and spread of water inside the equipment are avoided.

[0098] To optimize the above technical solution, the bottom partition 600 is provided with a first fastening hole and a second fastening hole 603. The first fastening hole is used to connect the bottom partition 600 and the upper shell 700, and the second fastening hole 603 is used to connect the bottom partition 600 and the lower shell. Waterproof baffles 604 extending vertically upward are provided on the edges of the first fastening hole and the second fastening hole 603.

[0099] Specifically, the upper housing 700 preferably has a semi-enclosed structure, with its bottom connected to the bottom partition 600 through a first fastening hole, and the lower housing preferably has a semi-enclosed structure, with its top connected to the bottom partition 600 through a second fastening hole 603.

[0100] Specifically, the first and second buckle holes 603 are preferably square holes. The bottom partition 600 is snapped to the upper housing 700 and the bottom partition 600 is snapped to the lower housing. The shape of the buckle can be adjusted according to the structural strength requirements of the portable device, which will not be elaborated here.

[0101] Specifically, the bottom partition 600 is also provided with a wiring hole 605 for wiring, and a waterproof baffle 604 extending vertically upward is provided on the edge of the wiring hole 605.

[0102] Specifically, the shape of the waterproof baffle 604 can be flexibly designed according to the shape of the waterproof component required. For example, a hollow cylindrical baffle 602 can be provided at the screw connection between the shell plate 100 and the bottom partition plate 600 and at the wiring hole 605, and a hollow cuboid baffle can be provided at the first fastening hole and the second fastening hole 603.

[0103] In summary, the waterproof lens, the first sealing component, the second sealing component 502, the waterproof baffle 604, and the fixing frame 500 together form an integrated waterproof structure for the display component. The button structure, together with the button structure, provides effective and comprehensive waterproof protection for the electronic control board 401 and other components of the portable device, such as the battery pack and compressor. This improves the structural stability and waterproof performance of the portable device, ensuring its stable operation and long service life in outdoor environments.
