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. However, in these technologies, the overall length of the lanyard cannot be adjusted to suit the user's needs. Specifically, users may want to adjust the lanyard length for a more comfortable experience depending on the usage scenario and their requirements. For example, a longer lanyard might be needed when hanging the power bank on a bag or around the neck; in other situations, a shorter lanyard might be preferred for easier carrying and operation. This fixed-length lanyard design limits the user's flexibility in different scenarios, causing some inconvenience. Utility Model Content

[0052] 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.

[0053] 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.

[0054] 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.

[0055] In related technologies, the overall length of the power bank's lanyard cannot be adjusted according to the user's needs. Specifically, when using a power bank, users may want to adjust the lanyard length for a more comfortable experience depending on the usage scenario and their needs. For example, a longer lanyard might be needed when hanging the power bank on a bag or around the neck; in other situations, users may prefer a shorter lanyard for easier carrying and operation. This fixed-length power bank lanyard design limits the user's flexibility in different scenarios, causing some inconvenience.

[0056] 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.

[0057] Specifically, the portable power bank 100 includes a power bank body 110, a data cable assembly 120, a cable housing assembly 140, and a connection assembly 160. See also... Figures 1-2 The 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.

[0058] See Figures 1-2The data cable assembly 120 is used for electrical connection between the power bank body 110 and the electronic device. The cable housing assembly 140 is detachably connected to the data cable assembly 120 so that the cable housing assembly 140 and the data cable assembly 120 together enclose a carrying space 150. It is understood that when the cable housing assembly 140 and the first data cable are combined, they can form a ring-shaped space (i.e., the carrying space 150), allowing the user to insert their hand or fingers into the carrying space 150 for easy carrying of the portable power bank 100. When the portable power bank 100 needs to be used, the first plug 122 or the second plug 123 can be detached from the cable 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 the carrying space 150 can be formed solely by the cable housing assembly 140 and the first data cable, or it can be formed together with other structures (such as the second data cable described later).

[0059] Specifically, see Figures 2-5 The connecting component 160 connects the housing assembly 140 and the power bank body 110. The connecting component 160 is configured to move relative to the housing assembly 140 to adjust its length between the housing assembly 140 and the power bank body 110. With the connecting component 160 configured as described above, the user can adjust its length as needed, making the portable power bank 100 suitable for various usage scenarios and providing a more comfortable user experience. When the carrying space 150 is not needed, the length can be minimized to reduce redundant connecting component 160 structures. In some embodiments, the connecting component 160 can adjust its length through its own structure; in other embodiments, the connecting component 160 can adjust its length by cooperating with other structures.

[0060] As can be seen, the portable power bank 100 of this utility model includes a power bank body 110, a data cable assembly 120, a cable shell assembly 140, and a connecting assembly 160. The data cable assembly 120 is used to electrically connect the power bank body 110 and the electronic device. The cable shell assembly 140 includes a cable shell assembly 140 and a connecting assembly 160. The cable shell assembly 140 and the data cable assembly 120 are detachably connected so that the cable shell assembly 140 and the data cable assembly 120 together enclose a carrying space 150. The connecting assembly 160 connects the cable shell assembly 140 and the power bank body 110. The connecting assembly 160 is configured to move relative to the cable shell assembly 140 to adjust the length of the connecting assembly 160 between the cable shell assembly 140 and the power bank body 110. Compared with the fixed-length power bank lanyard design of related technologies, in the solution of this utility model, the user can adjust the length of the connecting assembly 160 according to needs, making the user experience of the portable power bank 100 better.

[0061] The following further explains the various methods for adjusting the length dimension; see [link to relevant documentation]. Figure 3 In the first type of adjustment method, the connecting component 160 includes a first connecting end 161 and a second connecting end 162. The first connecting end 161 has multiple third connecting positions stacked on the second connecting end 162 for adjusting the length. Each third connecting position is distributed along the direction from the housing assembly 140 towards the power supply body 110. It is understood that by stacking the first connecting end 161 on the second connecting end 162, the length can be adjusted by changing the ratio or position of the stacking of the first connecting end 161 on the second connecting end 162.

[0062] See Figure 4 In the second type of adjustment method, the adjustment can be achieved by changing the position of the connecting component 160 connected to the power bank body 110. Specifically, in some embodiments, the connecting component 160 has multiple first connection positions for connecting to the power bank body 110 to adjust the length. It is understood that the power bank body 110 can provide multiple first connection positions for connecting the connecting component 160, so that switching the connecting component 160 between these first connection positions can change the length. More specifically, in some embodiments, the power bank body 110 includes a snap-fit ​​slot with multiple snap-fit ​​positions for snapping the connecting component 160, thereby changing the length by snapping the connecting component 160 to different snap-fit ​​positions. Similarly, the adjustment can also be achieved by changing the position of the connecting component 160 connected to the cable shell assembly 140. Specifically, in some embodiments, the connecting component 160 has multiple second connection positions for connecting to the cable shell assembly 140 to adjust the length. The setting of the second connection positions can be referred to the relevant description of the first connection positions in the foregoing embodiments, and will not be repeated here.

[0063] See Figure 5In the third type of adjustment method, the adjustment can be achieved by changing the size of the connecting component 160 housed inside the power bank body 110. Specifically, in some embodiments, the power bank body 110 has a first receiving cavity 114 and a first protruding opening 115. The first protruding opening 115 connects the first receiving cavity 114 to the outside. The connecting component 160 passes through the first protruding opening 115 and is configured to adjust the size of the component located in the first receiving cavity 114 to adjust the length. Similarly, the adjustment can also be achieved by changing the size of the connecting component 160 housed inside the cable housing assembly 140. Specifically, in some embodiments, the cable housing assembly 140 has a second receiving cavity and a second protruding opening. The second protruding opening connects the second receiving cavity to the outside. The connecting component 160 passes through the second protruding opening and is configured to adjust the size of the component located in the second receiving cavity to adjust the length.

[0064] It should be noted that the above-mentioned method of adjusting the length by changing the position of the connecting component 160 connected to the power bank body 110 and changing the size of the connecting component 160 housed inside the power bank body 110 can be achieved by the user driving the connecting component 160, or by other components driving the connecting component 160.

[0065] See Figures 6-8 In some embodiments, the data cable assembly 120 includes a cable 121, a first plug 122, and a second plug 123. The cable 121 connects the first plug 122 and the second plug 123. The cable housing assembly 140 is detachably connected to the first plug 122 and the second plug 123. To accommodate the data cable, the cable housing assembly 140 includes a receiving groove 141, through which the first plug 122 and the second plug 123 pass and are engaged with the receiving groove 141. It should be noted that the first plug 122 and the second plug 123 can be fixedly connected to the cable housing assembly 140, or they can be confined within the receiving groove 141 / hole. Specifically, taking the first plug 122 as an example, in some embodiments, the first plug 122 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 the first plug 122 is fixed in the receiving groove 141 when no external force is applied; 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 122 is not subjected to a force in a specific direction, the first plug 122 cannot be dislodged from the receiving groove 141 along the extension direction of the receiving groove 141, and the first plug 122 can still move slightly at this time.

[0066] The following describes the more specific structural configuration of the wire housing assembly 140. (See below for more details.) Figures 6-9In some embodiments, the receiving groove 141 includes a first groove 1411 and a second groove 1412. The connecting assembly 160 connects to one end of the wire housing assembly 140 along the first direction X. The first groove 1411 and the second groove 1412 are both connected to the other end of the wire housing assembly 140 along the first direction X. The first groove 1411 has a first slot 14111, and the second groove 1412 has a second slot 14121. Along the second direction Y, which is perpendicular to the first direction X, the first slot 14111 and the second slot 14121 are arranged opposite to each other and have opposite opening directions. The first plug 122 is received in the first groove 1411 and can extend from the first slot 14111. The second plug 123 is received in the second groove 1412 and can extend from the second slot 14121. It is understandable that the first groove 1411 and the second groove 1412 are spaced apart and each is responsible for accommodating the first wire plug 122 and the second wire plug 123, which helps to enhance the fixing reliability of the first wire plug 122 and the second wire plug 123.

[0067] To make the removal and placement of the first wire plug 122 more convenient, see Figures 6-9 In some embodiments, the maximum size of the first slot 14111 is larger than the maximum size of the first plug 122 along a third direction Z perpendicular to the first direction X and the second direction Y. With this size setting, the user can directly remove the first plug 122 from the first slot 14111 without deformation of the first plug 122 or the wire housing assembly 140. In addition to the above embodiments, in other embodiments, the maximum size of the first slot 14111 is smaller than the maximum size of the first plug 122. This makes it less likely for the first plug 122 to detach in its stored state; in this case, the first plug 122 can detach from the receiving slot 141 through deformation of the first plug 122 itself or deformation of the wire housing assembly 140.

[0068] Similarly, for the removal and placement of the second plug 123, see [reference needed]. Figures 6-9 In some embodiments, the maximum size of the second slot 14121 is larger than the maximum size of the second plug 123 along a third direction Z perpendicular to the first direction X and the second direction Y. Further details regarding the second slot 14121 can be found in the description of the first slot 14111 in the above embodiments, and will not be repeated here.

[0069] To prevent the first wire plug 122 from disengaging from the receiving groove 141 along the first direction X, see [reference needed] Figures 6-9In some embodiments, along the first direction X, the groove wall of the first groove 1411 can abut against the side of the first plug 122 away from the connecting assembly 160. The groove wall abutting against the first plug 122 can be the inner wall surface of the end of the housing assembly 140, or a limiting protrusion disposed within the receiving groove 141. Further, in some embodiments, while the first plug 122 is limited by one side of the receiving groove 141, it can also extend from the other side of the receiving groove 141 along the first direction X; in other embodiments, the first plug 122 cannot extend from the receiving groove 141 along the first direction X.

[0070] Similarly, for the second data line, see [link to relevant documentation]. Figures 6-9 In some embodiments, along the first direction X, the wall of the second groove 1412 can abut against the side of the second plug 123 away from the connecting assembly 160. The above-described configuration of the second plug 123 and the second groove 1412 can be referred to the relevant configuration of the first plug 122 and the first groove 1411 in the foregoing embodiments, and will not be repeated here.

[0071] The following describes the more detailed structural design of the data cable assembly 120. (See also...) Figure 10-11 In some embodiments, the second plug 123 includes a first plug 1231 and a second plug 1232 adapted to respectively connect electronic devices. The interface type or interface specification of the first plug 1231 and the second plug 1232 may be the same or different. Figure 10-11 In the illustrated embodiment, the first plug 1231 and the second plug 1232 have different interface types. With this configuration, the user can connect the other end of the first plug 122 to a power source (which can be a power bank 110 or other power supply device), and then connect the first plug 1231 and the second plug 1232 to different electronic devices. Based on the configuration of the first plug 1231 and the second plug 1232, in some embodiments, the housing assembly 140 includes a partition 142. Along a third direction Z perpendicular to the first direction X and the second direction Y, the partition 142 separates the first groove 1411, so that the first plug 1231 and the second plug 1232 are located on opposite sides of the partition 142. It is understood that the partition 142 can separate the first plug 1231 and the second plug 1232 within the receiving cavity (it can be completely separated or partially separated). In this case, the two sides of the partition 142 can be used to limit the first plug 1231 and the second plug 1232, making their installation more stable.

[0072] To improve the fit between the cable housing assembly 140 and the data cable, see [link / reference]. Figure 8In some embodiments, the first plug 122 includes a first interface portion and a first covering portion, with the first covering portion sleeved around the outer periphery of the first interface portion. The first interface portion is the interface structure for achieving electrical connection, and the first covering portion can also be referred to as the outer sheath or protective sleeve of the first interface portion. The main functions of the first covering portion may include protecting the wire 121, protecting the interface, resisting tensile stress, and providing electrical protection. The elastic modulus of the first covering portion may be less than the elastic modulus of the groove wall of the receiving groove 141. Through the above arrangement, the first plug 122 extending into the receiving groove 141 achieves interference assembly and enhances the assembly damping effect. For example, in some embodiments, the groove wall of the receiving groove 141 is made of a hard plastic material, specifically one of PC (polycarbonate), ABS (acrylonitrile-butadiene-styrene copolymer), or PC+ABS, while the material of the first covering portion is a soft plastic material, specifically TPE (thermoplastic elastomer). In other embodiments, the elastic modulus of the first covering portion is greater than the elastic modulus of the groove wall of the receiving groove 141, and it also enhances the assembly damping effect. It should be noted that when the first covering portion has multiple parts with different elastic moduli, the elastic modulus of the first covering portion described above is the average elastic modulus of each part of the first covering portion. Similarly, when the groove wall of the receiving groove 141 has multiple parts with different elastic moduli, the elastic modulus of the groove wall of the receiving groove 141 described above is the average elastic modulus of each part of the groove wall of the receiving groove 141. Similarly, for the assembly of the second wire plug 123 and the receiving groove 141, the second wire plug 123 includes a second interface portion and a second covering portion. The second covering portion is sleeved on the outer periphery of the second interface portion, and the elastic modulus of the second covering portion is less than the elastic modulus of the hole wall of the receiving groove 141. The setting and effect of the elastic modulus of the second covering portion and the groove wall of the receiving groove 141 described above can be referred to the relevant descriptions of the foregoing embodiments, and will not be repeated here.

[0073] Further, see Figure 10-11 In some embodiments, the cable 121 includes a first cable body 1211 and a second cable body 1212. One end of the first cable body 1211 and one end of the second cable body 1212 are both connected to a first plug 122. The other ends of the first cable body 1211 and the second cable body 1212 are respectively connected to a first plug 1231 and a second plug 1232. It can be understood that, corresponding to the arrangement of the first plug 1231 and the second plug 1232, the first cable body 1211 and the second cable body 1212 are provided to supply power to both of them respectively. Since the first cable body 1211 and the second cable body 1212 are both connected to the first plug 122, the first cable body 1211 and the second cable body 1212 together form a carrying space 150. Compared with the arrangement of only one cable body forming a lanyard, the lanyard formed by the double-layer cable body can have higher strength and better user feel.

[0074] For specific settings regarding the connection of the data cable assembly 120 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 1 In 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 data cable assembly 120 is connected to the third end face 113 or is entirely disposed on 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 data cable assembly 120, making space utilization more reasonable and making it easier for users to lift the portable power bank 100 using the carrying space 150.

[0075] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model.
