[0031] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0032] Most current digital product housings are provided with buttons, which can be used to effectively control the opening and closing of the digital product, or to switch and adjust some functions. There are also various ways to install and fix the housing and the buttons.

[0033] However, existing buttons are generally fixed and assembled using hot melt. This installation method not only leads to an increase in manufacturing costs, but also has a certain probability of damaging the appearance of the product. In addition, the hot melt installation method is difficult to solve the problems of button eccentricity and button sinking.

[0034] Please refer to Figures 1 to 3 In order to solve the above technical problems, the present application proposes a mobile power housing assembly 100 and a mobile power supply 1000, wherein the mobile power housing assembly 100 includes a housing 1, at least two mounting posts 2 and a button 3. The shell 1 has an inner surface 1a and an outer surface 1b relative to each other, and is provided with a first mounting hole 11 that passes through the inner surface 1a and the outer surface 1b. At least two mounting columns 2 are spaced apart around the first mounting hole 11. The mounting column 2 includes a connecting portion 21 and a limiting portion 22. The connecting portion 21 is protruding from the inner surface 1a of the shell 1. The limiting portion 22 is connected to an end of the connecting portion 21 away from the inner surface 1a and a limiting surface 221 facing the inner surface 1a of the shell 1 is formed between the limiting portion 22 and the connecting portion 21; and the button 3 includes a pressing portion 31 and at least two matching portions 32. The pressing portion 31 is passed through the first mounting hole 11. Each matching portion 32 is located in the shell 1 and is correspondingly provided with a second mounting hole 321. Each matching portion 32 is sleeved on each connecting portion 21 through the corresponding second mounting hole 321, and the matching portion is located between the limiting surface 221 and the inner surface 1a of the shell 1.

[0035] It is understandable that since the housing assembly 100 includes at least two mounting posts 2, and the mounting posts 2 are spaced apart around the first mounting hole 11, so that the button 3 can be assembled corresponding to the first mounting hole 11. In the actual installation process, when the second mounting hole 321 of the matching portion 32 of the button 3 is sleeved on the connecting portion 21 of the mounting post 2, due to the number of mounting posts 2, the pressing portion 31 of the button 3 can be fixed at multiple points, thereby ensuring that the button 3 has a high alignment accuracy after installation, ensuring that the pressing portion 31 of the button 3 can be assembled in a center corresponding to the first mounting hole 11, thereby reducing the probability of the button 3 being eccentric after installation, and making the gap between the periphery of the button 3 and the wall of the first mounting hole 11 uniform. At the same time, the matching portion 32 is limited by the limiting portion 22 of the mounting post 2, thereby effectively limiting the movement range of the button 3, reducing the occurrence of loosening or falling off of the button 3 during use, and thereby ensuring that the button 3 is firmly installed.

[0036] Furthermore, since the limiting portion 22 of the mounting column 2 can limit the installation of the button 3, there is no need to use hot melt to fix the button 3 and the mounting column 2, thereby simplifying the installation process. It is only necessary to assemble the button 3 and the mounting column 2, and there is no need to add a hot melt step for reinforcement, thereby saving the cost of the hot melt process.

[0037] Please refer to Figure 3 The cross-sectional area of the limiting portion 22 gradually increases from the end away from the connecting portion 21 to the end closer to the connecting portion 21. Specifically, the end of the limiting portion 22 away from the connecting portion 21 is a small end, and the end of the limiting portion 22 closer to the connecting portion 21 is a large end. The small end of the limiting portion 22 facilitates plugging and mating with the second mounting hole 321, while the large end of the limiting portion 22 forms a limiting surface 221 facing the inner surface 1a of the housing 1. This ensures that after the second mounting hole 321 and the connecting portion 21 are installed and mated, the limiting surface 221 can be used to limit the movement of the mating portion 32 of the button 3. Therefore, this configuration of the limiting portion 22 ensures convenient installation while achieving a good limiting effect.

[0038] Please continue to refer to Figure 1 and Figure 3 The shell assembly 100 includes two mounting columns 2, and the two mounting columns 2 are respectively located on opposite sides of the first mounting hole 11. In some embodiments, in order to save costs and facilitate installation, the number of mounting columns 2 is two, which can effectively position the button 3. Furthermore, the two mounting columns 2 are relatively located on both sides of the first mounting hole 11, presenting a symmetrical layout. On the one hand, it can improve the stability of the button 3 during installation and use. The two mounting columns 2 can better disperse the stress of the button 3 when it is subjected to force, and can reduce deformation or damage caused by uneven force on both sides; on the other hand, the two relatively arranged mounting columns 2 can facilitate assembly and maintenance. During the installation process, it is easier to locate the positions of the two mounting columns 2, which facilitates the installation of the button 3 on the mounting columns 2, reduces the possibility of assembly errors, and facilitates subsequent maintenance and replacement of parts.

[0039] Furthermore, in some embodiments, the button 3 has a length direction and a width direction, and the dimension of the button 3 in the length direction is greater than the dimension of the button 3 in the width direction. The corresponding first mounting hole 11 also has a length direction and a width direction. The two mounting columns 2 are distributed on both sides of the first mounting hole 11 along the length direction. The button 3 and the two mounting columns 2 are assembled. Such an arrangement facilitates fixing the button 3 along the length direction of the button 3, enhances the stability of the installation of the button 3, and reduces the shaking phenomenon of the button 3 during operation.

[0040] In some embodiments, the mating portion 32 is an elastic mating portion. During actual installation, there are certain assembly errors between the first mounting hole 11, the mounting post 2, and the pressing portion 31 and mating portion 32 of the button 3. By configuring the mating portion 32 as an elastic mating portion, it is able to deform during installation and operation, which, to a certain extent, can accommodate assembly errors between various components and facilitate the mating installation of the button 3. Furthermore, the mating portion 32 is an elastic mating portion that can return to its original shape after deformation, thereby ensuring the normal function of the button 3. After pressing the button 3 to activate or deactivate the switch 200, the elastic mating portion returns to its original shape, allowing the button 3 to return to its original position.

[0041] Please continue to refer to Figure 2 and Figure 4 The mating portion 32 includes an elastic mating arm 322 and an elastic connecting arm 323. The elastic mating arm 322 is spaced apart from the pressing portion 31, and the elastic connecting arm 323 is connected between the elastic mating arm 322 and the pressing portion 31. The elastic mating arm 322 is provided with a second mounting hole 321. The inner wall of the second mounting hole 321 includes a first side wall 321a and a second side wall 321b opposite to each other. Part of the first side wall 321a and / or part of the second side wall 321b are recessed in a direction away from each other to mount the connecting portion 21. In an embodiment of the present application, the mating portion 32 includes an elastic mating arm 322 and an elastic connecting arm 323, so the mating portion 32 has a certain elastic deformation ability. During the assembly process, even if there is a slight dimensional deviation, it can be adapted through the elastic deformation of the mating portion 32, thereby reducing the difficulty of assembly. In the present application, the elastic mating arm 322 and the mounting column 2 are connected and assembled. Since the mounting column 2 has a limiting portion 22, during installation, the recess of the second mounting hole 321 of the elastic mating arm 322 can be installed corresponding to the limiting portion 22. Even if there is a certain position error and dimensional error, it can be adapted through the deformation between the first side wall 321a or the second side wall 321b, thereby improving the success rate of assembly.

[0042] In addition, the elastic matching arm 322 and the elastic connecting arm 323 make the button 3 feel softer when pressed, reduce the impact force, and improve the pressing feel of the button 3. The elastic setting can extend the service life of the button 3 and reduce wear or breakage caused by repeated pressing. The recessed design of the first side wall 321a or the second side wall 321b makes the connecting part 21 more stable during installation, reducing loosening or falling off due to vibration or collision during use.

[0043] Furthermore, the middle portion of the first side wall 321a and / or the middle portion of the second side wall 321b are recessed in directions away from each other to facilitate installation of the connection portion 21. In some embodiments, the middle portion of the first side wall 321a is recessed in a direction away from the second side wall 321b. This recess is used to cooperate with the connection portion 21, so that the recessed portion can be used to position and secure the connection portion 21 during installation. Similarly, the recess in the middle portion of the second side wall 321b can also achieve a corresponding effect. This arrangement facilitates installation of the connection portion 21 via the recessed position in the middle portion formed by the first side wall 321a, the second side wall 321b, or both the first side wall 321a and the second side wall 321b, thereby achieving positioning of the connection portion 21.

[0044] During the specific installation process, the second mounting hole 321 must first be inserted into the limiting portion 22 and then inserted into the connecting portion 21. The limiting portion 22 has a limiting surface 221 facing the inner surface 1a of the housing 1. Therefore, when the second mounting hole 321 and the limiting portion 22 are assembled, they need to produce a certain deformation to accommodate the insertion of the limiting portion 22. In the embodiment of the present application, the limiting portion 22 is assembled through the recessed portion and the second mounting hole 321. Since the elastic engagement arm 322 has a certain elasticity, the first side wall 321a and the second side wall 321b can move away from each other within a certain limit. Therefore, when the limiting portion 22 is assembled, the distance between the recesses in the middle of the first side wall 321a and the second side wall 321b is increased, reducing the difficulty of installing the limiting portion 22. When assembled, the first side wall 321a and the second side wall 321b can return to their original shapes, and the limiting portion 22 can achieve the effect of limiting the installation of the elastic engagement arm 322.

[0045] It is understood that the mating portion 32 includes two elastic connecting arms 323, which are located on opposite sides of the elastic mating arm 322 along the first direction X. The elastic mating arms and the pressing portion are spaced apart along the second direction Y, with the first direction X being perpendicular to the second direction Y. The symmetrical distribution of the two elastic connecting arms 323 along the first direction X provides a better supporting connection effect, connecting the pressing portion 31 and the elastic mating arms 322, achieving the mating installation of the pressing portion 31, realizing the pressing function of the button 3, and better dispersing the force applied to the button 3 during pressing, thereby ensuring that the button 3 is less likely to undergo lateral displacement when subjected to external force, reducing the possibility of excessive local force on the button 3, and ensuring smoother movement of the button 3 during pressing and rebounding.

[0046] Please continue to refer to Figure 4The pressing portion 31 has a pressing surface 31a and a back surface 31b relative to each other. The pressing surface 31a is exposed to the housing 1 through the first mounting hole 11, and the back surface 31b is provided with a mounting groove 311. The pressing surface 31a of the pressing portion 31 is used to be close to the user's operating side, facilitating the user to operate the pressing surface 31a through the first mounting hole 11. The back surface 31b of the pressing portion 31 is used to be close to the switch 200 in the housing 1. When the user operates, the mounting groove 311 on the back surface 31b of the pressing portion 31 can be close to the switch 200 to trigger the switch 200, thereby realizing the various functions required by the user. In some other embodiments, the mounting groove 311 can be used to fix other components, which has strong expandability.

[0047] Please refer to Figure 5 The housing 1 is also provided with a plurality of light-through holes 12 distributed at intervals. Each light-through hole 12 passes through the inner surface 1a and the outer surface 1b of the housing 1. The housing assembly 100 further includes a mating protrusion 4 connected to the inner surface 1a of the housing 1 and protruding from the inner surface 1a of the housing 1. The mating protrusion 4 is provided between two adjacent light-through holes 12. The design of the light-through holes 12 allows light inside the housing 1 to pass through the housing 1 smoothly, thereby indicating the working status or other information of the mobile power supply 1000. The mating protrusion 4 can be used to cooperate with the installation of other components in the housing 1. Since the mating protrusion 4 is between the two light-through holes 12, it can be used to block the propagation path of light between the two light-through holes 12, thereby achieving a certain light-shielding effect.

[0048] Second, please refer to Figures 6 to 8 In an embodiment of the present application, a mobile power supply 1000 is further provided. The mobile power supply 1000 includes a housing assembly 100 of the mobile power supply. The specific structure of the housing assembly 100 of the mobile power supply is referred to the above embodiment. Since the mobile power supply 1000 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 one by one here.

[0049] In addition, the mobile power supply 1000 also includes a battery cell and a circuit board assembly. The battery cell is installed in the shell. The circuit board assembly is located in the shell 1 and is fixed relative to the shell 1. The circuit board assembly further comprises a mainboard and a switch 200, which is connected and fixed to the mainboard. The switch 200 corresponds to the pressing portion 31. The fixed position of the switch 200 ensures the stability and reliability of the electrical connection of the switch 200, reduces the problem of poor electrical connection, and reduces the failure rate caused by poor contact. In addition, the fixed position of the switch 200 ensures that each press accurately triggers the switch 200, improving the consistency and reliability of operation.

[0050] Please refer to Figure 7Since the switch 200 is generally soldered on a circuit board, the positioning tolerance is large. In the prior art, pressing the button 3 sometimes fails to accurately trigger the switch 200. In addition, in some cases, the button 3 sinks, making it difficult for the user to press the button 3. In an embodiment of the present application, the mobile power supply 1000 further includes an elastic pad 300, which abuts between the switch 200 and the pressing portion 31. It is understandable that the elastic pad 300 abuts against the switch 200 and the pressing portion 31 respectively. When the user presses the button 3, the elastic pad 300 can be squeezed to elastically deform, thereby triggering the switch 200. This ensures that the pressing portion 31 can reliably trigger the switch 200 when pressed, and the elastic pad 300 can return to its original shape, so that it can quickly reset after the button 3 is released, effectively preventing the button 3 from collapsing.

[0051] In some embodiments, please refer to Figure 4 and Figure 8 The button 3 has a pressing surface 31a and a back surface 31b relative to each other. The back surface 31b is provided with a mounting groove 311. The elastic pad 300 is installed in the mounting groove 311. The side of the elastic pad 300 close to the switch 200 is flush with the notch of the mounting groove 311 or protrudes from the notch of the mounting groove 311, so that the elastic pad 300 and the switch 200 can be abutted. Such a setting can facilitate the installation of the elastic pad 300. It is only necessary to press the elastic pad 300 into the mounting groove 311. In other embodiments, the elastic pad 300 can also be fixed to the back surface 31b of the button 3 in other ways, such as a snap connection, an adhesive connection, etc. This application is not limited here, as long as it can achieve the installation effect of the elastic pad 300.

[0052] In addition, the material of the elastic pad 300 includes a silicone pad, a rubber pad, and other pads made of elastic materials, which are not limited in this application.

[0053] Please refer to Figure 5 、 Figures 7 to 10 The housing 1 is further provided with a plurality of light holes 12 spaced apart from each other. Each light hole 12 extends through the inner surface 1a and the outer surface 1b of the housing 1. The mobile power supply 1000 further includes a light-emitting component 400. The light-emitting component 400 includes a lamp holder 5 and a plurality of lamp posts 6 mounted on the lamp holder 5. The lamp holder 5 is located within the housing 1 and is fixed relative to the housing 1. Each lamp post 6 is disposed through each light hole 12. The light from the lamp posts 6 can directly illuminate the exterior of the housing 1 through the light holes 12, clearly displaying the operating status or other indication information of the mobile power supply 1000. Each lamp post 6 indicates different status information. Therefore, the plurality of lamp posts 6 and the plurality of light holes 12 are spaced apart from each other and do not interfere with each other, ensuring that the information indicated by each lamp post 6 is independent.

[0054] Furthermore, the housing assembly 100 further includes a mating protrusion 4 protruding from the inner surface 1a of the housing 1. The mating protrusion 4 is disposed between two adjacent light holes 12. The lamp holder 5 includes a mounting plate 51 and a plurality of light-shielding ribs 52. The mounting plate 51 has a first side surface and a second side surface facing each other. The plurality of lamp posts 6 are connected and protrude from the first side surface. The plurality of light-shielding ribs 52 are connected and protrude from the second side surface. Each light-shielding rib 52 is provided for each lamp post 6. The mounting plate 51 is provided with a mating groove 511 between two adjacent lamp posts 6. The mating groove 511 extends through the first and second side surfaces and is used to insert the mating protrusion 4. The mating protrusion 4, in combination with the mating groove 511 on the mounting plate 51, can secure the position of the lamp holder 5 and enhance its stability. The engagement between the mating protrusion 4 and the mating groove 511 of the lamp holder 5 prevents the lamp holder 5 from loosening or shifting after installation, thereby improving the stability of the overall structure.

[0055] In addition, the shading rib 52 can prevent the light from the lamp post 6 from being scattered, thereby improving the concentration of light. In the embodiment of the present application, in order to install the lamp holder 5 on the mating protrusion 4 of the shell 1, a mating groove 511 is correspondingly provided at the lamp holder 5. The mating groove 511 is located between adjacent lamp posts 6. The light from the lamp post 6 can easily pass through the mating groove 511 and be scattered to the light-through hole 12 corresponding to the adjacent lamp post 6. Therefore, the mating protrusion 4 at the shell 1 is also used to cooperate with the mating groove 511 to shield the mating groove 511 and prevent the light from the adjacent lamp post 6 from being scattered through the mating groove 511 into the corresponding light-through hole 12, so as to ensure the independence of the light of each lamp post 6.

[0056] In some embodiments, the mating protrusion 4 is provided with a connecting groove corresponding to the mating groove 511. The bottom surfaces of the mating groove 511 and the connecting groove abut against each other, forming a snap-fit fit between the mating protrusion 4 and the lamp holder 5. This ensures convenient assembly. On the other hand, the multiple mating protrusions 4 and the multiple mating grooves 511 of the lamp holder 5 snap together, enhancing the stability of the assembly between the housing 1 and the light-emitting element 400 and preventing the light-emitting element 400 from falling off. Furthermore, the snap-fit connection replaces the conventional hot-melt connection method, reducing installation steps, improving installation efficiency, and saving hot-melt costs.
