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 cannot reliably limit the movement of the data cable, resulting in poor cable retention. Utility Model Content

[0003] The main purpose of this utility model is to propose a data cable assembly and a portable power bank. The solution of this utility model is to make the housing more stable in accommodating the first plug by switching the position of the limiting member, and to make the operation of picking up and putting down the first plug more convenient.

[0004] To achieve the above objectives, the embodiments of this utility model adopt the following technical solutions:

[0006] The housing has a receiving groove and a first opening communicating with the receiving groove, the axis of the first opening being a first direction;

[0007] The data cable body includes interconnecting wires and a first plug, the first plug being received in a receiving groove;

[0008] The limiting member is movably connected to the housing. The orthographic projection of the limiting member on the projection plane perpendicular to the first direction is the first projection, and the orthographic projection of the first plug on the projection plane is the second projection. The limiting member can switch between the first position and the second position. When the limiting member is in the first position, the first projection and the second projection at least partially overlap. When the limiting member is in the second position, the first projection and the second projection are arranged at intervals so that the first plug can extend out of the receiving groove from the first opening.

[0009] In some embodiments, the limiting member is configured to rotate circumferentially about a rotation axis perpendicular to the first direction to switch positions between a first position and a second position.

[0010] In some embodiments, the data cable assembly further includes a locking member movably connected to the housing. The locking member is capable of switching between a third position and a fourth position. When the locking member is in the third position, it abuts against a limiting member to restrict the limiting member from moving from the first position to the second position. When the locking member is in the fourth position, the locking member and the limiting member are spaced apart so that the limiting member can switch between the first position and the second position.

[0011] In some embodiments, the limiting member is configured to rotate circumferentially about a rotation axis perpendicular to the first direction to switch positions between a first position and a second position. When the locking member is in the third position, the locking member can abut against one side of the limiting member along the circumferential direction to restrict the limiting member from moving from the first position to the second position. When the locking member is in the fourth position, the locking member and the limiting member are arranged at a distance to allow the limiting member to switch positions between the first position and the second position.

[0012] The housing has a perforation, and a locking member is inserted through the perforation in a second direction perpendicular to the first direction and the axis of rotation. The locking member can move within the perforation in a direction parallel to the axis of rotation to switch positions between a third position and a fourth position.

[0013] In some embodiments, the locking member includes an operating part and a locking part connected to each other. The limiting member has a locking groove and a clearance hole. The operating part passes through the clearance hole and extends out of the receiving groove. The locking part is located in the locking groove and can slide in the locking groove. The locking groove has a groove bottom surface on one side along the first direction. The clearance hole penetrates the groove bottom surface along the first direction. When the locking member is in the third position, the locking member can abut against one side of the groove bottom surface along the circumferential direction. When the locking member is in the fourth position, the locking member and the clearance hole are circumferentially opposite each other, so that the limiting member can pass through the clearance hole during circumferential rotation.

[0014] In some embodiments, the housing further has a second opening communicating with the receiving groove. Along a first direction, the second opening is arranged opposite to the first opening, and one end of the data cable body away from the first opening extends out of the receiving groove through the second opening. The housing has an abutting groove wall on one side along the first direction, the abutting groove wall defining the second opening and capable of abutting against the first plug located in the receiving groove along the first direction.

[0015] In some embodiments, at least two of the limiting member, the abutment groove wall, and the inner wall of the housing along a direction perpendicular to the first direction are arranged at intervals from the first plug so that the first plug can move within the receiving groove.

[0016] In some embodiments, the data cable body further includes a second plug, the cable includes a first connecting end and a second connecting end, the first connecting end and the second connecting end are respectively connected to the first plug and the second plug, and the second plug is accommodated in a receiving groove; the housing also has a second opening communicating with the receiving groove, along a first direction, one end of the cable is provided with the first connecting end and the second connecting end and passes through the second opening, and the other end of the cable is located outside the housing and together with the housing encloses a carrying space.

[0017] In some embodiments, the data cable body further includes a second plug, with the two ends of the cable connected to the first plug and the second plug respectively. The housing also includes a partition, which divides the receiving groove along a second direction perpendicular to the first direction, so that the first plug and the second plug are respectively received on both sides of the partition. The data cable assembly includes two limiting members, which are respectively disposed on both sides of the partition along the second direction.

[0018] A second aspect of the present invention also provides a portable power bank, including a data cable assembly of any of the above embodiments; and a power bank body, the power bank body being used for power supply.

[0019] The data cable assembly also includes a connector that connects the housing to the power bank body.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] The data cable assembly of this utility model includes a housing, a data cable body, and a limiting member. The housing has a receiving groove and a first opening communicating with the receiving groove, the axis of the first opening being a first direction. The data cable body includes interconnecting wires and a first plug, the first plug being received in the receiving groove. The limiting member is movably connected to the housing. The orthographic projection of the limiting member on a projection plane perpendicular to the first direction is the first projection, and the orthographic projection of the first plug on the projection plane is the second projection. The limiting member can switch between a first position and a second position. When the limiting member is in the first position, the first projection and the second projection at least partially overlap. When the limiting member is in the second position, the first projection and the second projection are spaced apart, so that the first plug can extend out of the receiving groove from the first opening. Compared to related technologies that rely on snap-fit ​​structures on the cable housing or damping connections between the data cable and the cable housing for fixation, in this invention, when the limiting member is in the first position, it faces the first plug to restrict the first plug from extending out of the receiving groove from the first opening. When the limiting member is in the second position, it no longer obstructs the movement of the first plug out of the receiving groove from the first opening. Therefore, by switching the position of the limiting member, this invention enables the housing to more stably accommodate the first plug and makes the removal and placement of the first plug more convenient.

[0042] 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

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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 cooperation between the data cable and the cable shell. This connection method cannot reliably limit the data cable, resulting in poor fixing effect of the data cable.

[0047] 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.

[0048] For details, see Figures 1-2 The data cable assembly 100 includes a housing 110, a data cable body 120, and a limiting member 130. The housing 110 has a receiving groove 111 and a first opening 112 communicating with the receiving groove 111. The axial direction of the first opening 112 is defined as the first direction X. The data cable body 120 includes a wire 121 and a first plug 122 connected to each other, the first plug 122 being received in the receiving groove 111. The data cable body 120 is used for power transmission from the power bank body 210. The wire 121 is defined as a strip-shaped portion of the data cable body 120 with uniform dimensions (e.g., the cross-section of the wire 121 can be circular or strip-shaped). The first plug 122 is larger than the wire 121 and is used to match the interface of a power device. The outer periphery of the first plug 122 is suitable for the user to hold and apply force to facilitate insertion of the first plug 122 into the power device.

[0049] Specifically, see Figures 1-6The limiting member 130 is movably connected to the housing 110. The orthographic projection of the limiting member 130 onto a projection plane perpendicular to the first direction X is the first projection, and the orthographic projection of the first plug 122 onto the projection plane is the second projection. The limiting member 130 can switch between a first position and a second position. When the limiting member 130 is in the first position, the first projection and the second projection at least partially overlap. When the limiting member 130 is in the second position, the first projection and the second projection are spaced apart, so that the first plug 122 can extend out of the receiving groove 111 from the first opening 112. It can be understood that, under the above-mentioned projection settings, when the limiting member 130 is in the first position, the limiting member 130 can face the first plug 122 to restrict the first plug 122 from extending out of the receiving groove 111 from the first opening 112. When the limiting member 130 is in the second position, the limiting member 130 no longer obstructs the movement of the first plug 122 from extending out of the receiving groove 111 from the first opening 112. Users can switch the position of the limiting member 130 as needed. For example, when the data cable assembly 100 is idle and not in use, the limiting member 130 can be controlled to be in the first position so that the first plug 122 can be more stably accommodated in the receiving groove 111. When the data cable assembly 100 needs to be used, the limiting member 130 can be controlled to be in the second position so that the first plug 122 can be taken out from the first opening 112.

[0050] As can be seen, the data cable assembly 100 of this utility model includes a housing 110, a data cable body 120, and a limiting member 130. The housing 110 has a receiving groove 111 and a first opening 112 communicating with the receiving groove 111, the axial direction of the first opening 112 being the first direction X. The data cable body 120 includes a wire 121 and a first plug 122 connected to each other, the first plug 122 being received in the receiving groove 111. The limiting member 130 is movably connected to the housing 110. The orthographic projection of the limiting member 130 on a projection plane perpendicular to the first direction X is the first projection, and the orthographic projection of the first plug 122 on the projection plane is the second projection. The limiting member 130 can switch between a first position and a second position. When the limiting member 130 is in the first position, the first projection and the second projection at least partially overlap. When the limiting member 130 is in the second position, the first projection and the second projection are arranged at intervals, so that the first plug 122 can extend out of the receiving groove 111 from the first opening 112. Compared to related technologies that rely on snap-fit ​​structures on the cable housing or damping connections between the data cable and the cable housing for fixation, in this invention, when the limiting member 130 is in the first position, it faces the first plug 122 to restrict the first plug 122 from extending out of the receiving groove 111 from the first opening 112. When the limiting member 130 is in the second position, it no longer obstructs the movement of the first plug 122 from extending out of the receiving groove 111 from the first opening 112. Therefore, by switching the position of the limiting member 130, this invention enables the housing 110 to more stably accommodate the first plug 122 and makes the removal and placement of the first plug 122 more convenient.

[0051] The following describes the more detailed settings of the limit component 130. (See below for more details.) Figures 1-6 In some embodiments, the limiting member 130 is configured to rotate circumferentially about a rotation axis L perpendicular to the first direction X, so as to switch positions between a first position and a second position. During the switching process between the first and second positions, the limiting member 130 may rotate only in one direction or rotate bidirectionally. In other embodiments, the limiting member 130 may also employ other forms of motion for position switching; the following description uses the embodiment where the limiting member 130 rotates circumferentially to switch positions between the first and second positions as an example.

[0052] See Figures 1-6In some embodiments, the data cable assembly 100 further includes a locking member 140, configured to restrict the position switching of the limiting member 130 between a first position and a second position. Specifically, in some embodiments, the locking member 140 is movably connected to the housing 110, and the locking member 140 can switch between a third position and a fourth position. When the locking member 140 is in the third position, it abuts against the limiting member 130 to restrict the limiting member 130 from moving from the first position to the second position. When the locking member 140 is in the fourth position, the locking member 140 and the limiting member 130 are spaced apart to allow the limiting member 130 to switch between the first position and the second position. With the limiting member 130 rotating circumferentially, the above-described configuration makes it easier for the locking member 140 to perform its locking function through abutment.

[0053] For more details, see Figures 5-7 In some embodiments, the housing 110 has a through-hole 113, and a locking member 140 passes through the through-hole 113 along a second direction Y perpendicular to the first direction X and the rotation axis L. The locking member 140 is movable within the through-hole 113 in a direction parallel to the rotation axis L to switch positions between a third position and a fourth position. The wall of the through-hole 113 can be used to restrict the movement of the locking member 140, allowing the locking member 140 to switch positions by sliding within the through-hole 113. In other embodiments, the position switching of the limiting member 130 and / or the position switching of the locking member 140 can be performed by an automatic drive device (e.g., a motor), thereby eliminating the need for manual operation.

[0054] For the structure of locking element 140, see Figures 4-7In some embodiments, the locking member 140 includes an operating part 141 and a locking part 142 connected to each other. The operating part 141 and the locking part 142 can be two parts of a single component that are integrally connected. The limiting member 130 has a locking groove 131 and a clearance hole 132. The operating part 141 passes through the through hole 113 and extends out of the receiving groove 111. The user can manually operate the operating part 141 that extends out of the receiving groove 111 from the through hole 113. The locking part 142 is located in the locking groove 131 and can slide within the locking groove 131. Furthermore, in some embodiments, the locking groove 131 has a groove bottom surface 1311 on one side along the first direction X, and the clearance hole 132 penetrates the groove bottom surface 1311 along the first direction X. When the locking member 140 is in the third position, the locking member 140 can abut against one side of the groove bottom surface 1311 along the circumferential direction. When the locking member 140 is in the fourth position, the locking member 140 and the clearance hole 132 are circumferentially opposite each other, so that the limiting member 130 can pass through the clearance hole 132 during circumferential rotation. Through the clearance hole 132 provided above, when the locking member 140 is in the third position, the locking member 140 can face the part of the groove bottom surface 1311 without the clearance hole 132 along the circumferential direction, so that the locking member 140 and the groove bottom surface 1311 can abut against each other. When the locking member 140 is in the fourth position, the locking member 140 no longer restricts the circumferential rotation of the limiting member 130.

[0055] To further restrict the movement of the first plug 122, see Figures 5-7 In some embodiments, the housing 110 further has a second opening 114 communicating with the receiving groove 111. Along the first direction X, the second opening 114 is arranged opposite to the first opening 112, and the end of the data cable body 120 away from the first opening 112 extends out of the receiving groove 111 through the second opening 114. The housing 110 has an abutment wall 115 on one side along the first direction X, which defines the second opening 114 and can abut against the first plug 122 located in the receiving groove 111 along the first direction X. Through the abutment action of the abutment wall 115 at the second opening 114, the first plug 122 can be prevented from coming out of the second opening 114, 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.

[0056] To make the data cable assembly 100 easier to use, see [link / reference]. Figures 5-6In some embodiments, at least two of the limiting member 130, the abutting groove wall 115, and the inner wall of the housing 110 along a direction perpendicular to the first direction X are spaced apart from the first plug 122, so that the first plug 122 can move within the receiving groove 111. This arrangement ensures that when the limiting member 130 is in the first position, the first plug 122 has a certain amount of movement without dislodging from the receiving groove 111, eliminating the need for the connecting member 160 used to fix the first plug 122 to the housing 110. For example, in some embodiments, the receiving groove 111 has a rectangular cross-section along a direction perpendicular to the first direction X. When the limiting member 130 is in the first position, after the first plug 122 moves along the first direction X to its extreme position in the receiving groove 111, the first plug 122 is abutted by the limiting member 130 or the abutting groove wall 115. At this time, the first plug 122 is spaced apart from at least three surfaces of the rectangular receiving groove 111.

[0057] See Figures 1-6 In some embodiments, the data cable body 120 further includes a second plug 123, and the cable 121 includes a first connecting end 1211 and a second connecting end 1212. The first connecting end 1211 and the second connecting end 1212 are respectively connected to the first plug 122 and the second plug 123. The second plug 123 is accommodated in a receiving groove 111. Along the first direction X, a second opening 114 is arranged opposite to the first opening 112.

[0058] Along the first direction X, one end of the wire 121 is provided with a first connecting end 1211 and a second connecting end 1212 and passes through the second opening 114. The other end of the wire 121 is located outside the housing 110 and together with the housing 110, forms a carrying space 150. With the above-mentioned wire 121 configuration, when the limiting member 130 is in the second position, both the first plug 122 and the second plug 123 can move away from the carrying space 150 along the first direction X (the user can hold the wire 121 and push or pull the first plug 122 and / or the second plug 123 out of the receiving groove 111). The second plug 123 can also be limited by the above-mentioned limiting member 130, and the first plug 122 and the second plug 123 can both be limited by the same limiting member 130, or they can be limited by different limiting members 130. Specifically, in some embodiments, the two ends of the cable 121 are respectively connected to a first plug 122 and a second plug 123. The housing 110 also includes a partition 116. Along a second direction Y perpendicular to the first direction X and the rotation axis L, the partition 116 divides the receiving groove 111 so that the first plug 122 and the second plug 123 are respectively received on both sides of the partition 116. The data cable assembly 100 includes two limiting members 130, which are respectively disposed on both sides of the partition 116 along the second direction Y. It can be understood that the partition 116 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, two limiting members 130 can be respectively provided on both sides of the partition 116. The setting of the partition 116 makes the removal and placement of the first plug 122 and the second plug 123 more independent, and the partition 116 makes the first plug 122 and the second plug 123 less prone to shaking and more stable in position. In some embodiments, the interface type and specifications of the first plug 122 and the second plug 123 are the same; in other embodiments, the interface types or specifications of 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. Other limiting settings for the second plug 123 can refer to the limiting settings for the first plug 122 in the foregoing embodiments, and will not be repeated here. In other embodiments, the limiting member 130 may not be provided for the second plug 123, or the second plug 123 may be detachably and fixedly connected to the housing 110 in any suitable manner.

[0059] A second aspect of this utility model also provides a portable power bank 200, including a data cable assembly 100 from any of the above embodiments and a power bank body 210, the power bank body 210 being used for power supply. It is understood that the power bank body 210 is the main body of the portable power bank 200, which may include a housing and various components such as a battery and circuit board disposed inside the housing for providing charging and discharging functions, and the housing may have a charging and discharging interface for connecting a first plug 122 and a second plug 123. Depending on the requirements, the power bank body 210 may have any structural shape, such as a rectangular structure, a cubic structure, a disc structure, etc.

[0060] See Figure 1 In some embodiments, the data cable assembly 100 further includes a connector 160, which connects the housing 110 and the power bank body 210. The connector 160 can connect the housing 110 and the power bank body 210 in any suitable manner, and can be a detachable connection or a non-detachable connection. Along the first direction X, the connector 160 can be connected to the end of the housing 110 that has a first opening 112.

[0061] Thanks to the improvements made to the data cable assembly 100 in the above embodiments, the portable power bank 200 of the second aspect of this utility model has the same technical effects as the data cable assembly 100 in the above embodiments. Further details will not be provided here.

[0062] 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.
