Description

Technical Field

[0001] This utility model relates to the field of mobile power technology, and in particular to a data cable assembly and 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. In one type of design, one end of the data cable is electrically connected to the power bank body, while the other end extends out and is detachably connected to a cable shell, thus forming a lanyard structure. This design combines the functions of a data cable and a lanyard, making it convenient for users to carry the power bank. However, in these related technologies, the fixed connection between the data cable and the cable shell mainly relies on a snap-fit ​​structure on the cable shell or a damping fit between the data cable and the cable shell. This connection method has poor reliability and is prone to instability. Utility Model Content

[0003] The main purpose of this utility model is to provide a data cable assembly and a portable power bank. In the solution of this utility model, the connection between the shell and the data cable body is more stable through the first snap-fit ​​structure and the second snap-fit ​​structure that are adapted to each other.

[0044] 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

[0045] 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.

[0046] 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.

[0047] 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.

[0048] In related technologies, the fixed connection between the data cable and the cable shell mainly relies on the snap-fit ​​structure on the cable shell or the damping fit between the data cable and the cable shell. This connection method has poor reliability and is prone to unstable fixing.

[0049] In view of this, see Figures 1-7 This utility model provides a data cable assembly 100 for a portable power bank 200. The portable power bank 200, 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 its energy storage medium and is primarily used to charge portable electronic products (such as mobile phones and laptops) in situations where no external power supply is available. Its working principle involves storing electrical energy in a built-in battery and then outputting it through appropriate voltage and current to provide the necessary power to electronic devices.

[0050] For details, see Figures 1-4 The data cable assembly 100 includes a housing 110, a data cable body 120, a first snap-fit ​​structure 130, and a second snap-fit ​​structure 140. The housing 110 has a receiving groove 111 and a first opening 112 communicating with the receiving groove 111. The data cable body 120 includes a cable 121, a first plug 122, and a second plug 123. The two ends of the cable 121 are respectively connected to the first plug 122 and the second plug 123. Both the first plug 122 and the second plug 123 are received in the receiving groove 111, so that the housing 110 and the data cable body 120 together enclose a carrying space 300. The data cable body 120 is used for power transmission to the power bank body 210. In some embodiments, the interface type and specifications between the first plug 122 and the second plug 123 are the same; in other embodiments, the interface types or specifications between the first plug 122 and the second plug 123 are different, for example, the interface type of the first plug 122 is Type-C, and the interface type of the second plug 123 is Micro USB. It should be noted that, taking the engagement of the first plug 122 as an example, the disassembly of the housing 110 and the first plug 122 can be either completely separated from the data cable body 120, or only the first plug 122 can be separated, while the wire 121 of the data cable body 120 is still threaded through the housing 110.

[0051] It is understood that, in order to accommodate the data cable body 120, the first plug 122 and the second plug 123 are accommodated in the receiving groove 111. When the housing 110 and the data cable body 120 are combined, they can jointly form an annular space (i.e., the carrying space 300). The user can insert their hand or fingers into the carrying space 300 to carry the portable power bank 200. When the portable power bank 200 needs to be used, the first plug 122 and the second plug 123 are separated from the housing 110, so that the portable power bank 200 can be used normally for charging and discharging. The carrying space 300 can be of any shape and size, and there is no limitation here. In addition, it should be noted that in this utility model, the description is based on the specific state in which the housing 110 and the data cable body 120 are connected and jointly enclose the carrying space 300.

[0052] Specifically, in order to securely connect the housing 110 to the first plug 122 and the second plug 123, see [reference needed]. Figures 4-6 Along a second direction Y perpendicular to the first direction X, the first snap-fit ​​structure 130 protrudes towards the side closer to the second snap-fit ​​structure 140, and along the second direction Y, the second snap-fit ​​structure 140 is recessed away from the first snap-fit ​​structure 130, with the first snap-fit ​​structure 130 extending into the second snap-fit ​​structure 140. Based on this, in the first snap-fit ​​configuration, the inner circumference of the housing 110 is provided with the first snap-fit ​​structure 130, and the outer circumferences of the first plug 122 and the second plug 123 are both provided with the second snap-fit ​​structure 140. In the second snap-fit ​​configuration, the inner circumference of the housing 110 is provided with the second snap-fit ​​structure 140, and the outer circumferences of the first plug 122 and the second plug 123 are both provided with the first snap-fit ​​structure 130. Through the cooperative arrangement of the protruding and recessed structures, the first plug 122 and the housing 110 can snap together, and the second plug 123 and the housing 110 can snap together, forming a more stable fixed connection. After snapping, the outer contours of the two can be completely or partially fitted. When the data cable body 120 is needed, the user can apply force to separate the first snap-fit ​​structure 130 from the second snap-fit ​​structure 140, so that both the first plug 122 and the second plug 123 can extend out of the receiving groove 111 through the first opening 112.

[0053] As can be seen, the data cable assembly 100 of this utility model includes a housing 110, a data cable body 120, a first snap-fit ​​structure 130, and a second snap-fit ​​structure 140. The housing 110 has a receiving groove 111 and a first opening 112 communicating with the receiving groove 111. The data cable body 120 includes a cable 121, a first plug 122, and a second plug 123. The two ends of the cable 121 are respectively connected to the first plug 122 and the second plug 123. The first plug 122 and the second plug 123 are both received in the receiving groove 111, so that the housing 110 and the data cable body 120 together form a carrying space 300. The axial direction of the first opening 112 is a first direction X. Along the first direction X, the first plug 122 and the second plug 123 can both extend out of the receiving groove 111 through the first opening 112. Along the second direction Y, which is perpendicular to the first direction X, the first snap-fit ​​structure 130 protrudes towards the side close to the second snap-fit ​​structure 140. Along the second direction Y, the second snap-fit ​​structure 140 is recessed towards the side away from the first snap-fit ​​structure 130, and the first snap-fit ​​structure 130 extends into the second snap-fit ​​structure 140. The first snap-fit ​​structure 130 is provided on the inner periphery of the housing 110, and the second snap-fit ​​structure 140 is provided on the outer periphery of both the first plug 122 and the second plug 123; alternatively, the second snap-fit ​​structure 140 is provided on the inner periphery of the housing 110, and the first snap-fit ​​structure 130 is provided on the outer periphery of both the first plug 122 and the second plug 123. Compared to related technologies that rely on snap-fit ​​structures on the cable housing or on damping cooperation between the data cable and the cable housing to form a fixed connection, the present invention uses the mutually adaptable first snap-fit ​​structure 130 and second snap-fit ​​structure 140 to make the connection between the housing 110 and the data cable body 120 more stable.

[0054] For ease of explanation, the following description uses an embodiment in which the inner periphery of the housing 110 is provided with a first snap-fit ​​structure 130, and the outer periphery of the first plug 122 and the outer periphery of the second plug 123 are provided with a second snap-fit ​​structure 140.

[0055] For better card-connection performance, please refer to [link / reference]. Figures 4-6In some embodiments, the receiving groove 111 has a bottom surface 1111, which faces the data cable body 120 along the second direction Y. Along the first direction X, the first snap-fit ​​structure 130 has opposing first side surfaces 131 and second side surfaces 132. The minimum angle between the first side surface 131 and the bottom surface 1111 is smaller than the minimum angle between the second side surface 132 and the bottom surface 1111. Taking the engagement of the first plug 122 as an example, through the aforementioned angle settings, the slope of the first side surface 131 is smaller, making it easier for the first plug 122 to slide within the receiving groove 111 along the direction from the first side surface 131 to the second side surface 132. The slope of the second side surface 132 is larger, making it less likely for the first plug 122 to slide within the receiving groove 111 along the direction from the second side surface 132 to the first side surface 131. Specifically, in some embodiments, along the first direction X, the first side 131 is located on the side of the first latching structure 130 closer to the first opening 112, and the second side 132 is located on the side of the first latching structure 130 away from the first opening 112. That is, when the user needs to use the data cable body 120, the data cable body 120 can be pushed out of the receiving groove 111 from the first opening 112 along the first direction X. In this process, the second side 132 with a larger slope plays a certain role in obstruction, making it more difficult for the data cable body 120 to come out when it is not subjected to the force of the user. Conversely, if the data cable body 120 is idle, the user can push the data cable body 120 into the receiving groove 111 from the first opening 112 in the opposite direction. In this process, the first side 131 with a smaller slope makes it easier for the part of the data cable body 120 without the second latching structure 140 to pass over the first latching structure 130, making the receiving operation of the data cable body 120 less obstructed. Based on the first side 131 and the second side 132 configured above, the two opposite sides of the second snap-fit ​​structure 140 along the first direction X can be adapted to the shapes of the first side 131 and the second side 132 respectively, or the slopes of the two opposite sides of the second snap-fit ​​structure 140 along the first direction X can be the same.

[0056] To ensure that both the first side surface 131 and the second side surface 132 provide good contact, in some embodiments, the minimum included angle between the first side surface 131 and the bottom surface 1111 of the groove is φ1, and the minimum included angle between the second side surface 132 and the bottom surface 1111 of the groove is φ2, satisfying the following conditions: 10°≤φ1≤35°, 70°≤φ2≤90°. For example, φ1 can be one of 10°, 20°, 30°, and 35°, and φ2 can be one of 70°, 80°, and 90°.

[0057] In some embodiments, the second snap-fit ​​structure 140 has opposing third and fourth sides, and the minimum angle between the third side and the bottom surface 1111 of the groove is smaller than the minimum angle between the fourth side and the bottom surface 1111 of the groove. The arrangement of the third and fourth sides in the above embodiments can be similar to the arrangement of the first side 131 and the second side 132 in the foregoing embodiments, and can achieve the same effect, so it will not be described again here.

[0058] To make the data cable itself 120 easier to use, see Figures 4-6 In some embodiments, the inner periphery of the housing 110 is provided with a first snap-fit ​​structure 130, and the first plug 122 is provided with a second snap-fit ​​structure 140 on each side along the second direction Y, and the second plug 123 is provided with a second snap-fit ​​structure 140 on each side along the second direction Y. It is understood that since both the first plug 122 and the second plug 123 have a second snap-fit ​​structure 140 on each side, when the user snaps the first plug 122 and the second plug 123 into the receiving groove 111, there is no need to distinguish between the front and back sides of the first plug 122 and the second plug 123.

[0059] The following describes the specific structure of the housing 110; see [link / reference]. Figures 4-7 In some embodiments, the housing 110 includes an open slot wall 115 having an open slot 1151 communicating with a receiving slot 111 along a second direction Y, so that the data cable body 120 can extend from the receiving slot 111 through the open slot 1151. In some embodiments, there may be only one open slot wall 115 and open slot 1151, facing one of the first plug 122 and the second plug 123; see also Figures 4-7In other embodiments, there are two open slot walls 115 and open slot openings 1151, located on opposite sides of the housing 110, allowing both the first plug 122 and the second plug 123 to be removed from the open slot opening 1151. Along the first direction X, the open slot wall 115 includes a first slot wall 1152 and a second slot wall 1153 connected to each other. The first slot wall 1152 and the second slot wall 1153 together define the open slot opening 1151. The maximum size of the open slot opening 1151 located in the first slot wall 1152 is smaller than the maximum size of the first plug 122, and the maximum size of the open slot opening 1151 located in the second slot wall 1153 is larger than the maximum size of the first plug 122. It is understood that the first slot wall 1152 and the second slot wall 1153 are two parts of the open slot wall 115. Taking the interaction between the open slot 1151 and the first plug 122 as an example, with the above-mentioned arrangement, the first slot at the first slot wall 1152 is smaller, which can abut and restrict the first plug 122 along the second direction Y, thereby restricting it from coming out of the receiving slot 111. The first slot at the second slot wall 1153 is larger, which makes it easier for the first plug 122 to be taken out from there. The housing 110 can prevent the first plug 122 from coming out in the storage state, and can also allow the first plug 122 to come out of the receiving slot 111 after being subjected to the force of the user, through the deformation of the first slot wall 1152 or the first plug 122, or by moving to make the first plug 122 avoid the first slot wall 1152.

[0060] Further, see Figure 7 In some embodiments, along the first direction X, the first groove wall 1152 includes a first wall surface 1154 and a second wall surface 1155 connected to each other. The first wall surface 1154 connects the second wall surface 1155 and the second groove wall 1153. The maximum size of the open slot 1151 located in the first groove wall 1152 is larger than the maximum size of the open slot 1151 located in the second groove wall 1153. This arrangement ensures that the second groove wall 1153, the first wall surface 1154, and the second wall surface 1155 are connected to each other along the first direction X, and their respective opening sizes gradually decrease. The junction where the second groove wall 1153, the first wall surface 1154, and the second wall surface 1155 connect can be an arc-shaped surface to make the change in opening size between different positions smoother and to make the shape of the housing 110 more aesthetically pleasing.

[0061] See Figures 4-7In some embodiments, the housing 110 includes a partition 114 along the second direction Y, the partition 114 dividing the receiving groove 111 so that the first plug 122 and the second plug 123 are respectively received on both sides of the partition 114, and the data cable body 120 includes two first snap-fit ​​structures 130, the two first snap-fit ​​structures 130 being respectively disposed on both sides of the partition 114 along the second direction Y. It is understood that the partition 114 can separate the first plug 122 and the second plug 123 within the receiving cavity (it can be completely separated or partially separated). At this time, the two sides of the partition 114 can be respectively provided with the first snap-fit ​​structure 130 (one or more on one side). In conjunction with the above embodiment for the setting of the open slot 1151, in some embodiments, the partition 114 and the open slot 1151 are arranged opposite to each other along the second direction Y. After the first snap-fit ​​structure 130 is set on the partition 114, when the data cable body 120 needs to be used, the user can not only pull out (or push out) the data cable body 120 along the first direction X, but also make the data cable body 120 extend out of the open slot 1151 (or have a tendency to extend out), thereby making it easier for the first snap-fit ​​structure 130 and the second snap-fit ​​structure 140 to detach from each other.

[0062] To further limit the displacement of the data cable body 120, see [reference needed]. Figure 2 In some embodiments, the housing 110 further has a second opening 113 communicating with the receiving groove 111. The cable 121 passes through the second opening 113. Along the first direction X, the first opening 112 is located on the side of the cable housing away from the handle space 300, and the second opening 113 is located on the side of the cable housing closer to the handle space 300, so that the groove wall defining the second opening 113 can abut against the first plug 122 and the second plug 123 along the first direction X. Through the abutment action of the groove wall at the second opening 113, the first plug 122 and the second plug 123 can be prevented from coming out of the second opening 113, making the connection between the data cable body 120 and the housing 110 more stable. At the same time, the first opening 112 located on the other side of the housing 110 can face the charging port of the portable power bank 200, making the charging operation more convenient.
