Description

Technical Field

[0001] This utility model relates to the field of mobile power technology, and in particular to a portable mobile power supply. Background Technology

[0002] In recent years, to improve the portability and ease of use of power banks, designs have emerged that use the power bank's built-in data cable as a lanyard. One type of design involves two data cables, each extending from the power bank body and detachably connected to a cable shell, forming a lanyard structure. In this design, to prevent the cable shell from being in the middle of the lanyard and thus avoiding direct contact with the user while carrying the power bank, affecting the feel, the two data cables need to be of different lengths. However, this unequal length design brings several inconveniences. In daily use, the shorter cable may not meet the user's charging needs in certain scenarios. For example, when the device is placed at a distance, the shorter cable may not be able to reach the required charging distance, forcing the user to adjust the device's position or find alternative charging methods, increasing the inconvenience. Furthermore, the unequal length cables are prone to tangling and knotting during storage, affecting not only the cable's lifespan but also causing unnecessary trouble and inconvenience for the user.

[0049] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0050] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0051] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0052] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or," "and / or," or "and / or" throughout the text implies three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where A and B are simultaneously satisfied. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0053] In one type of design related to this technology, the data cable consists of two wires. The ends of the two wires extending from the power bank body are detachably connected to a cable shell, forming a lanyard structure. In this design, to prevent the cable shell from being in the middle of the lanyard and to avoid direct contact with the cable shell when carrying the power bank, thus affecting the user's handling, the two data cables need to be of different lengths. However, this unequal length design brings several inconveniences. In daily use, the shorter data cable may not meet the user's charging needs in certain scenarios. For example, when the device is placed at a distance, the shorter data cable may not be able to reach the required charging distance, forcing the user to adjust the device's position or find alternative charging methods, increasing the cumbersomeness of use. Furthermore, the unequal length data cables are prone to tangling and knotting during storage, not only affecting the lifespan of the data cables but also potentially causing unnecessary trouble and inconvenience to the user.

[0054] In view of this, see Figures 1-11 This utility model provides a portable power bank 100 in its embodiments. The portable power bank 100, also known as a power bank, is a portable charging device that integrates power supply and charging functions. It uses a lithium-ion battery as the energy storage medium and is mainly used to charge portable electronic products (such as mobile phones and laptops) in situations where there is no external power supply. Its working principle is to store electrical energy in the built-in battery and then output it through appropriate voltage and current to provide the required electrical energy to electronic devices.

[0055] Specifically, the portable power bank 100 includes a power bank body 110, a first data cable 120, a second data cable 130, and a cable housing assembly 140. See also... Figures 1-2The power bank body 110 is used for power supply. It is understood that the power bank body 110 is the main body of the portable power bank 100, which may include a shell, and various components such as a battery and circuit board disposed inside the shell for providing charging and discharging functions. The shell may have a charging and discharging interface for connecting a data cable. Depending on the requirements, the power bank body 110 can have any structural shape, such as a rectangular structure, a cube structure, a disk structure, etc. This utility model uses an embodiment where the power bank body 110 has a rectangular structure as an example for illustration.

[0056] See Figures 1-2 The first data cable 120 includes a first cable end 122 and a first cable plug 123. The first cable end 122 connects to the power bank body 110, and the first cable plug 123 extends out of the power bank body 110 for connecting to an electronic device. Specifically, the first cable end 122 electrically connects the first data cable 120 to the power bank body 110, and the first cable plug 123 connects to an electronic device or a power supply device. When connected to an electronic device, the first data cable 120 can transfer electrical energy from the power bank body 110 to the electronic device; when connected to a power supply device, the first data cable 120 can transfer electrical energy from the power supply device to the power bank body 110. Similarly, the second data cable 130 includes a second cable end 132 and a second cable plug 133. The second cable end 132 connects to the power bank body 110, and the second cable plug 133 extends out of the power bank body 110 for connecting to an electronic device. For the functions of the second cable end 132 and the second cable plug 133, please refer to the above description of the first cable end 122 and the first cable plug 123. It can be seen that the first data cable 120 and the second data cable 130 have similar functions, both being used for power transmission of the power bank body 110. In some embodiments, the interface type and specifications of the first data cable 120 and the second data cable 130 are the same; in other embodiments, the interface type or specifications of the first data cable 120 and the second data cable 130 are different, for example, the interface type of the first data cable 120 is Type-C, and the interface type of the second data cable 130 is Micro USB.

[0057] Regarding the first plug 123 and the second plug 133 configured above, the dimension of the first plug 123 extending out of the power bank body 110 is defined as the first length dimension. The dimension of the second plug 133 extending out of the power bank body 110 is defined as the second length dimension. Taking the first plug 123 as an example, it can be understood that the first length dimension is the length dimension from the end of the first data cable 120 away from the power bank body 110 (i.e., the interface end of the first plug 123) to the power bank body 110.

[0058] See Figures 5-7The cable housing assembly 140 is detachably connected to the first cable plug 123 and the second cable plug 133. Taking the first cable plug 123 as an example, the cable housing assembly 140 can be completely separated from the first data cable 120, or only the first cable plug 123 can be separated, while the wire portion of the first data cable 120 still passes through the cable housing assembly 140. The cable housing assembly 140, the first data cable 120, and the second data cable 130 together enclose a carrying space 150. It is understood that when the housing assembly 140 is combined with the first data cable 120 and the second data cable 130, the three together form a ring-shaped space (i.e., a carrying space 150). Users can insert their hands or fingers into the carrying space 150 to easily carry the portable power bank 100. When the portable power bank 100 needs to be used, the first cable plug 123 or the second cable plug 133 is detached from the housing assembly 140, allowing the portable power bank 100 to function normally for charging and discharging. The carrying space 150 can have any shape and size, and is not limited here. Furthermore, it should be noted that in this invention, the portable power bank 100 is described in the specific state of the housing assembly 140 connected to the first data cable 120 and the second data cable 130, together forming the carrying space 150. The data cables described in this invention all refer to the first data cable 120 and / or the second data cable 130.

[0059] Specifically, see Figure 2 and Figure 3 or Figure 2 and Figure 4 The power bank body 110 includes an adjustment structure 114, which is configured to adjust a first length dimension and / or a second length dimension. According to the adjustment structure 114, on the one hand, the user can adjust the size of the carrying space 150 as needed. When the carrying space 150 is not needed, the first data cable 120 and the second data cable 130 can be stored as much as possible inside the power bank body 110. On the other hand, in some applications, the cable housing assembly 140 needs to be positioned away from the area the user might touch after inserting their hand into the carrying space 150, in order to improve the feel of the lanyard formed by the cable housing assembly 140, the first data cable 120, and the second data cable 130. However, this arrangement would result in different lengths for the first data cable 120 and the second data cable 130. Therefore, by adjusting the function of the component, under the above-mentioned configuration, the user can still adjust the relative lengths of the first data cable 120 and the second data cable 130 as needed, avoiding inconvenience in using the data cables and making the data cables neater and more aesthetically pleasing.

[0060] As can be seen, the portable power bank 100 of this utility model includes a power bank body 110, a first data cable 120, a second data cable 130, and a cable housing assembly 140. The first data cable 120 has a first cable tail 122 and a first cable plug 123 at its two ends, and the second data cable 130 has a second cable tail 132 and a second cable plug 133 at its two ends. The cable housing assembly 140 is detachably connected to the first cable plug 123 and the second cable plug 133, so that the cable housing assembly 140, the first data cable 120, and the second data cable 130 together enclose a carrying space 150. The power bank body 110 includes an adjustment structure 114, which is configured to adjust a first length dimension and / or a second length dimension. Compared to related technologies that allow data cables to be used as lanyards and whose lengths cannot be adjusted, in this invention, users can adjust the length of the first data cable 120 or the second data cable 130 by adjusting the components, resulting in a better user experience for the portable power bank 100.

[0061] The following further describes various methods by which the adjusting component adjusts the first and second length dimensions. For ease of explanation, the following description uses an embodiment where the adjusting component only adjusts the first length dimension. See also Figure 2 and Figure 3 In the first type of adjustment method, the power bank body 110 has a receiving cavity 115 and an extension opening 116. The extension opening 116 connects the receiving cavity 115 to the outside, and both the first data cable 120 and the second data cable 130 pass through the extension opening 116. Simultaneously, the portions of the first data cable 120 and the second data cable 130 located in the receiving cavity 115 can be electrically connected to the power bank body 110. Regarding the adjustment function of the first data cable 120, in some embodiments, the adjustment structure 114 is configured to adjust the size of the first data cable 120 located in the receiving cavity 115 to adjust its first length dimension; similarly, regarding the adjustment function of the second data cable 130, in some embodiments, the adjustment structure 114 is configured to adjust the size of the second data cable 130 located in the receiving cavity 115 to adjust its second length dimension. Regarding the specific adjustment method of the adjustment component, taking the adjustment function of the first data line 120 as an example, in some embodiments, the adjustment component can be used to drive the first data line 120 so that the first data line 120 extends or retracts into the receiving cavity 115 under the driving action of the adjustment component; in some embodiments, the adjustment component can also be used to restrict the first data line 120 from extending or retracting into the receiving cavity 115.

[0062] More specifically, based on the type of adjustment component described in the above embodiments, in some embodiments, the adjustment structure 114 includes a first winding shaft disposed in the receiving cavity 115, and the first data cable 120 is wound around the first winding shaft. The adjustment structure 114 is configured to adjust the size of the first data cable 120 wound around the first winding shaft to adjust the first length dimension. In addition, the adjustment structure 114 may also include a locking member configured to fix the position of the first data cable 120 relative to the power bank body 110. In a specific embodiment, by setting the adjustment component, the user first pulls the first data cable 120 outward, so that the locking member is in the unlocked state. At this time, the first data cable 120 can slide within the protrusion opening 116. After adjusting to the target first length dimension, the user pulls the first data cable 120 outward again, so that the locking member is in the locked state, and the first length dimension is locked. Similarly, regarding the adjustment function of the second data line 130, in some embodiments, the adjustment structure 114 includes a second winding shaft disposed in the receiving cavity 115, the second data line 130 is wound around the second winding shaft, and the adjustment structure 114 is configured to adjust the size of the second data line 130 wound around the second winding shaft, thereby adjusting the second length dimension. The configuration of the second winding shaft can refer to the relevant description of the first winding shaft in the foregoing embodiments, and will not be repeated here. In addition, in some embodiments, the number of protruding openings 116 can be two, and the two protruding openings 116 can respectively pass through the first data line 120 and the second data line 130.

[0063] See Figure 2 and Figure 4 In the second type of adjustment method, the first wire tail end 122 has multiple first connection positions connected to the adjustment structure 114 for adjusting the first length dimension. It is understood that the adjustment structure 114 can provide multiple first connection positions that can connect to the first wire tail end 122, so that switching the first wire tail end 122 between the various first connection positions can change the first length dimension. More specifically, in some embodiments, the adjustment structure 114 is a snap-fit ​​groove with multiple snap-fit ​​positions that can snap the first wire tail end 122, thereby changing the first length dimension by snapping the first wire tail end 122 to different snap-fit ​​positions. Similarly, regarding the adjustment function of the second data line 130, in some embodiments, the second wire tail end 132 has multiple second connection positions connected to the adjustment structure 114 for adjusting the second length dimension. The setting of the second connection positions can refer to the relevant description of the first connection positions in the foregoing embodiments, and will not be repeated here.

[0064] For data cable accommodating, see Figures 5-11In some embodiments, the housing assembly 140 has a receiving groove 141 and a receiving hole 142, both of which are through-holes. The first plug 123 is received in the receiving groove 141, and the second plug 133 is received in the receiving hole 142. It should be noted that both the first plug 123 and the second plug 133 can be fixedly connected to the housing assembly 140, or they can be confined within the receiving groove 141 / hole. Specifically, taking the first plug 123 as an example, in some embodiments, the first plug 123 is snapped into the receiving groove 141 (which can be formed by the size of the receiving groove 141 to form an interference fit, or by other connection structures), so that when no external force is applied, the first plug 123 is fixed in the receiving hole 142; in other embodiments, the wire housing assembly 140 is provided with a limiting structure in the receiving groove 141, so that when the limiting structure is not unlocked or the first plug 123 is not subjected to a force in a specific direction, the first plug 123 cannot be dislodged from the receiving groove 141 along the extension direction of the receiving groove 141, and the first plug 123 can still move slightly at this time.

[0065] The following describes the more specific structural configuration of the cable housing assembly 140. For easy access to the data cable, please refer to [link / reference]. Figures 5-11In some embodiments, the centerline of the receiving groove 141 and the centerline of the receiving hole 142 are both parallel to the first direction X. Along the second direction Y, which is perpendicular to the first direction X, the side wall of the receiving groove 141 away from the receiving hole 142 is an open groove wall 1411. The open groove wall 1411 has a first slot 1412, which connects to the side of the receiving groove 141 near the first wire 121. The first plug 123 can extend out of the receiving groove 141 from the first slot 1412. The first slot 1412 connects to the side of the receiving groove 141 near the first wire 121. The wall of the receiving hole 142 surrounds the second plug 133. With the above arrangement, the first plug 123 can extend out of the receiving groove 141 from the first slot 1412 along the second direction Y. However, because the wall of the receiving hole 142 surrounds the second plug 133, the second plug 133 can only exit the receiving hole 142 along the first direction X. With the first slot 1412, the first plug 123 can be more easily removed from the receiving slot 141 compared to the second plug 133, and its use is no longer restricted by the cable housing assembly 140. Therefore, on the one hand, when the first plug 123 is needed, the user can quickly separate it from the cable housing assembly 140 through the first slot 1412, making the use of the first data cable 120 more convenient. On the other hand, when the second plug 133 is needed, the user can extend it from the receiving hole 142 along the first direction X. Since the wall of the receiving hole 142 is closed, the wire of the second plug 133 still passes through the receiving hole 142, thus the cable housing assembly 140 remains connected to the second data cable 130, effectively preventing the cable housing assembly 140 from being lost.

[0066] To make the removal and placement of the first plug 123 more convenient, see Figure 6 and Figure 8 In some embodiments, the opening direction of the first slot 1412 is the second direction Y, and along a third direction Z perpendicular to the first direction X and the second direction Y, the maximum size of the first slot 1412 is larger than the maximum size of the first plug 123. With the above-mentioned size setting, the user can directly remove the first plug 123 without deformation of the first plug 123 or the cable housing assembly 140. Furthermore, to make the first plug 123 more stably located within the receiving slot 141 in the stored state (i.e., forming a carrying space 150 and not subjected to user force), see [reference needed]. Figures 6-11In some embodiments, along the first direction X, the open slot wall 1411 includes a first slot wall 1413 and a second slot wall 1414 connected to each other. The first slot wall 1413 and the second slot wall 1414 together define a first slot 1412. The maximum size of the first slot 1412 located in the first slot wall 1413 is smaller than the maximum size of the first plug 123, and the maximum size of the first slot 1412 located in the second slot wall 1414 is larger than the maximum size of the first plug 123. It can be understood that the first slot wall 1413 and the second slot wall 1414 are two parts of the open slot wall 1411. The first slot 1412 at the first slot wall 1413 is smaller and can abut against and restrict the first plug 123 on one side along the second direction Y, thereby restricting its dislodgement from the receiving slot 141. The first slot 1412 at the second slot wall 1414 is larger and can facilitate the removal of the first plug 123 from there. Therefore, with the above-mentioned size settings, the housing assembly 140 can both prevent the first plug 123 from coming out in the storage state and allow the first plug 123 to come out of the receiving groove 141 after being subjected to the force of the user, through the deformation of the first groove wall 1413 / first plug 123, or by moving to allow the first plug 123 to avoid the first groove wall 1413.

[0067] Further, see Figures 6-11 In some embodiments, along the first direction X, the first groove wall 1413 includes a first wall surface 14131 and a second wall surface 14132 connected to each other. The first wall surface 14131 connects the second wall surface 14132 and the second groove wall 1414. The maximum size of the first slot 1412 located in the first groove wall 1413 is larger than the maximum size of the first slot 1412 located in the second groove wall 1414. This arrangement ensures that the second groove wall 1414, the first wall surface 14131, and the second wall surface 14132 are connected to each other along the first direction X, and their respective opening sizes gradually decrease. The junction where the second groove wall 1414, the first wall surface 14131, and the second wall surface 14132 connect can be an arc-shaped surface to make the change in opening size between different positions smoother and to make the appearance of the wire housing assembly 140 more aesthetically pleasing.

[0068] In addition to the configurations described in the above embodiments, in some other embodiments, the maximum size of the first slot 1412 is smaller than the maximum size of the first plug 123. This makes it less likely for the first plug 123 to come out of the receiving slot 141 when it is in the stored state. In this case, the first plug 123 can come out of the receiving slot 141 by deformation of the first plug 123 itself or by deformation of the wire housing assembly 140.

[0069] The following provides further details regarding the 150 cubic meter laptop space; please refer to [link / reference]. Figures 1-6In some embodiments, along a third direction Z perpendicular to the first direction X and the second direction Y, the first cable end 122 and the second cable end 132 are arranged opposite each other, and the carrying space 150 is located on one side of the cable housing assembly 140 along the third direction Z. This arrangement allows for a more rational arrangement of the first data cable 120 and the second data cable 130, reducing potential bending and twisting during connection and increasing the lifespan of the data cables.

[0070] Additionally, see Figure 6 In some embodiments, the first cable 121 is bent at one end near the first plug 123, with the bend center located near the power bank body 110, so that the first cable 121 defines a handle space 150 away from the power bank body 110. This handle space 150 away from the power bank body 110 is positioned opposite the connection points of the first cable tail 122 and the second cable tail 132 to the power bank body 110, providing a comfortable gripping position for the user. With this design, the bent first cable 121 is easy for the user to hold, and the cable housing assembly 140 is not close to the user's gripping position, thus improving the user experience.

[0071] To improve the fit between the cable housing assembly 140 and the data cable, see [link / reference]. Figure 7In some embodiments, the first plug 123 includes a first interface portion 1231 and a first covering portion 1232, with the first covering portion 1232 sleeved around the outer periphery of the first interface portion 1231. The first interface portion 1231 is an interface structure for achieving electrical connection, and the first covering portion 1232 can also be referred to as the outer sheath or protective sleeve of the first interface portion 1231. The main functions of the first covering portion 1232 may include protecting the wire, protecting the interface, resisting tensile stress, and providing electrical protection. The elastic modulus of the first covering portion 1232 can be less than the elastic modulus of the groove wall of the receiving groove 141. Through the above arrangement, the first plug 123 extending into the receiving groove 141 achieves interference assembly and enhances the assembly damping effect. For example, in some embodiments, the wall of the receiving groove 141 is made of a rigid rubber material, specifically one of PC (polycarbonate), ABS (acrylonitrile-butadiene-styrene copolymer), or PC+ABS, while the material of the first covering portion 1232 is a soft rubber material, specifically TPE (thermoplastic elastomer). In other embodiments, the elastic modulus of the first covering portion 1232 is greater than the elastic modulus of the wall of the receiving groove 141, and it can also enhance the assembly damping effect. It should be noted that when the first covering portion 1232 has multiple portions with different elastic moduli, the elastic modulus of the first covering portion 1232 described above is the average elastic modulus of each portion of the first covering portion 1232. Similarly, when the wall of the receiving groove 141 has multiple portions with different elastic moduli, the elastic modulus of the wall of the receiving groove 141 described above is the average elastic modulus of each portion of the wall of the receiving groove 141. Similarly, regarding the assembly of the second plug 133 with the receiving hole 142, the second plug 133 includes a second interface portion 1331 and a second covering portion 1332. The second covering portion 1332 is sleeved on the outer periphery of the second interface portion 1331, and the elastic modulus of the second covering portion 1332 is less than the elastic modulus of the hole wall of the receiving hole 142. The setting and effect of the elastic modulus of the second covering portion 1332 and the hole wall of the receiving hole 142 described above can be found in the relevant descriptions of the foregoing embodiments, and will not be repeated here.

[0072] For the specific settings of connecting the first wire end 122 and the second wire end 132 to the power bank body 110, please refer to [link / reference]. Figure 1 In some embodiments, each end face includes a first end face 111, a second end face 112, and a third end face 113. The first end face 111 is parallel to the second end face 112, and the third end face 113 connects the first end face 111 and the second end face 112. Specifically, in Figure 1In the illustrated embodiment, the power bank body 110 has a rectangular structure. The first end face 111 and the second end face 112 are the two largest opposite end faces of the rectangular structure. The third end face 113 is located on the side of the rectangular structure and is a vertical, annular end face connecting the first end face 111 and the second end face 112. Based on the above definition, in some embodiments, the first cable tail 122 and the second cable tail 132 are both connected to the third end face 113 or both pass through the third end face 113. It can be understood that the above arrangement utilizes the side of the power bank body 110 to connect the first data cable 120 and the second data cable 130, making space utilization more reasonable and making it easier for users to lift the portable power bank 100 using the carrying space 150.

[0073] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the contents of this utility model specification and drawings under the application concept of this utility model, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
