DETAILED DESCRIPTION

[0014] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0015] A power bank is a portable storage device that is primarily used as a portable charger for handheld mobile devices and other electronic products (e.g., wireless phones and laptops), especially in situations where there is no external power supply. Currently available power banks with built-in cables are inconvenient to carry.

[0016] Please refer to Figures 1 to 4 As shown, an embodiment of the present application provides a mobile power supply, which can fix the interface end 22 of the data cable 20 so that the data cable 20 of the mobile power supply can be bent to form a hanging or hand-held lanyard, which is convenient for users to carry.

[0017] Please refer to Figures 1 to 4 As shown, the mobile power supply includes a power supply body 10, a data line 20, a first limiting structure 30 and a second limiting structure 40. The data line 20 includes a connection end 21 for connecting to the power supply body 10, an interface end 22 for connecting to an external electronic device, and a transmission line body 23 arranged between the connection end 21 and the interface end 22; the first limiting structure 30 is provided on the power supply body 10. When the first limiting structure 30 is connected to the interface end 22, the first limiting structure 30 only allows the interface end 22 to move along the first direction a. The first direction a is the length of the power supply body 10. degree direction, width direction or thickness direction; a second limiting structure 40, the second limiting structure 40 has a first state and a second state; in the first state, the second limiting structure 40 is engaged with the interface end 22 so that the transmission line body 23 can be bent to form a hanging rope, and only allows the interface end 22 to move in the first direction a1 along the first direction; in the second state, the second limiting structure 40 is separated from the interface end 22, and the interface end 22 moves relative to the power supply body 10 in the first direction a1 along the first direction to realize the second limiting structure 40 switching from the first state to the second state.

[0018] In the embodiment of the present application, the mobile power supply of the present application is described by taking the first direction a as the thickness direction of the power supply body 10 as an example. At this time, the first limiting structure 30 limits the movement of the interface end 22 along the length direction and the width direction of the power supply body 10. It can be understood that the thickness direction, the length direction and the width direction of the power supply body 10 are all bidirectional; at the same time, for the convenience of subsequent description, in the embodiment of the present application, the first direction also has a second direction a2, and the vector direction of the first direction a1 is opposite to the vector direction of the second direction a2.

[0019] The power supply body 10 includes a battery cell and a shell. It can be understood that the battery cell is naturally arranged in the shell, the first limiting structure 30 is arranged on the shell, and the connection end 21 of the data cable 20 is fixedly connected to the shell and passes through the shell to be electrically connected to the battery cell.

[0020] The interface end 22 is used to connect an external electronic device and charge the external electronic device. In some embodiments of the present application, the interface end 22 includes an insulating part and a power connection part fixed on the insulating part. When the interface end 22 charges the electronic device, the power connection part is in the charging interface of the electronic device to charge the electronic device. The movement of the interface end 22 is limited by the cooperation of the insulating part and the first limiting structure 30 and the second limiting structure 40.

[0021] It can be understood that a power supply body 10 can be connected to multiple data cables 20, and the multiple data cables 20 can have the same or different interface ends 22, for example, a Micro USB interface, a type-A interface, a lightning interface, and a type-C interface, etc. In order to enable the interface end 22 of each data cable 20 to form a hanging rope under the restriction of the first limiting structure 30 and the second limiting structure 40, in some embodiments of the present application, the insulating portion of each interface end 22 is exactly the same. In this way, the interface end 22 of any data cable 20 can be restricted by the first limiting structure 30 and the second limiting structure 40 to form a hanging rope.

[0022] Based on the mobile power supply of the embodiment of the present application, the connection end 21 of the data line 20 is connected to the power supply body 10. When the interface end 22 of the data line 20 is connected to the power supply body 10, the first limiting structure 30 limits the movement of the interface end 22 in two directions of the length direction, width direction or thickness direction of the power supply body 10, so that the interface end 22 can only move along the remaining one direction; the second limiting structure 40 only allows the interface end 22 to move along the first direction a1 of the first direction in the first state, and limits the interface end 22 from moving in the opposite direction of the first direction a1 of the first direction. At this time, the data line 20 is subjected to external force. When the interface end 22 has a tendency to move in the opposite direction of the first direction a1 of the first direction (i.e., the first direction a2 of the first direction), the connection end 21 and the interface end 22 of the data cable 20 are fixed to the power supply body 10 to form a lanyard, and the user can hang or carry the mobile power supply through the data cable 20; the second limiting structure 40 allows the interface end 22 to move along the first direction a1 of the first direction in the second state, so as to release the restriction of the first limiting structure 30 on the interface end 22, so that the interface end 22 and the power supply body 10 are separated. At this time, the user can charge the external electronic device through the interface end 22.

[0023] In some embodiments of the present application, the second limiting structure 40 includes a snap-in slot 44 and a snap-in structure, one of the interface end 22 and the power supply body 10 is provided with a snap-in slot 44, and the other is provided with a snap-in structure; when the second limiting structure 40 is in the first state, the snap-in structure partially extends into the snap-in slot 44 and abuts against the slot wall of the snap-in slot 44; when the second limiting structure 40 is in the second state, the snap-in structure is outside the snap-in slot 44.

[0024] Since the snap-fit ​​structure and the snap-fit ​​groove 44 are respectively arranged on the interface end 22 and the power supply body 10, when the snap-fit ​​structure extends into the snap-fit ​​groove 44, the snap-fit ​​structure simultaneously connects the power supply body 10 and the interface end 22 to limit the interface end 22 from moving in the second direction a2 along the first direction. When the second limiting structure 40 is in the second state, the snap-fit ​​structure is outside the snap-fit ​​groove 44. At this time, the snap-fit ​​structure no longer limits the movement of the interface end 22 relative to the power supply body 10.

[0025] Please refer to Figure 2 and Figure 3 As shown, in some embodiments of the present application, the power supply body 10 or the interface end 22 is provided with a receiving groove 11, and the snap-fit ​​structure includes an elastic member 41 and a limiting member 42, and the elastic member 41 is in the receiving groove 11; when the second limiting structure 40 is in the first state, the limiting member 42 is partially in the receiving groove 11, and partially in the snap-fit ​​groove 44 and abuts against the groove wall of the snap-fit ​​groove 44; wherein, during the movement of the interface end 22 in the first direction a1 along the first direction, the limiting member 42 is forced to gradually shrink into the receiving groove 11 and compress the elastic member 41, so that the second limiting structure 40 is switched from the first state to the second state.

[0026] Part of the limiting member 42 is in the accommodating groove 11, and the remaining part is in the snap-fit ​​groove 44 and abuts against the groove wall of the snap-fit ​​groove 44, that is, part of the limiting member 42 is in the power supply body 10, and the remaining part is in the interface end 22, thereby limiting the movement of the interface end 22 in the second direction a2 along the first direction; when the interface end 22 moves in the first direction a1 along the first direction, it can force the limiting member 42 to gradually shrink into the accommodating groove 11, that is, the part of the limiting member 42 in the snap-fit ​​groove 44 gradually withdraws from the snap-fit ​​groove 44, so that the interface end 22 is separated from the power supply body 10; in this process, the limiting member 42 will compress the elastic member 41 to shrink the elastic member 41, and after the interface end 22 and the power supply body are separated, the compressed elastic member 41 rebounds and restores the limiting member 42 to its initial position.

[0027] The receiving groove 11 is used to accommodate the elastic member 41 and part of the limiting member 42. In the embodiment of the present application, there is no limitation on the depth, shape, etc. of the receiving groove 11, as long as the receiving groove 11 can completely accommodate the limiting member 42 and the elastic member 41.

[0028] The elastic member 41 is compressed during the process of the limiting member 42 gradually shrinking to the accommodating groove 11. After the interface end 22 is separated from the power supply body 10, the elastic member 41 relies on its own elastic potential energy to restore the limiting member 42 to its original position. The elastic member 41 in the embodiment of the present application includes but is not limited to various types of springs, elastic supports, rubber pads and air cushions.

[0029] It is understandable that, due to the small size of the interface end 22, providing a complex snap-fit ​​structure on the interface end 22 would not only reduce the strength of the interface end 22 but also place higher demands on the processing of the snap-fit ​​structure. Therefore, in the embodiment of the present application, the interface end 22 is provided with a snap-fit ​​groove 44, and the power supply body 10 is provided with a snap-fit ​​structure. In conjunction with the aforementioned power supply body 10 including a housing and a battery cell, the snap-fit ​​structure is provided on the housing. In conjunction with the aforementioned interface end 22 including an electrical connection portion and an insulating portion, the snap-fit ​​groove 44 is provided on the insulating portion.

[0030] Please refer to Figure 3 as well as Figure 4 As shown, in some embodiments of the present application, the limiting member 42 includes a clamping portion 421 and a guiding portion 422. When the second limiting structure 40 is in the first state, the clamping portion 421 is at least partially located in the clamping groove 44; the guiding portion 422 is located in the accommodating groove 11 and is connected to the clamping portion 421; at least one of the clamping portion 421 and the guiding portion 422 is slidably connected to the groove wall of the accommodating groove 11 along the depth direction of the accommodating groove 11.

[0031] The clamping portion 421 and the guiding portion 422 are slidably connected to the receiving groove 11 to guide the limiting member 42 along the depth direction of the receiving groove 11 , so that the limiting member 42 can only move along the depth direction of the receiving groove 11 .

[0032] When the engaging portion 421 is completely in the engaging groove 44, the guide portion 422 is naturally connected to the groove wall of the receiving groove 11 by sliding; when the engaging portion 421 is in the engaging groove 44, the guide portion 422 and / or the engaging portion 421 is connected to the groove wall of the receiving groove 11 by sliding, thereby realizing the sliding connection between the limiting member 42 and the groove wall of the receiving groove 11. Figure 1 As shown, in the specific embodiment of the present application, the clamping portion 421 is slidably connected to the groove wall of the accommodating groove 11.

[0033] Please refer to Figure 3 As shown, in some embodiments of the present application, the clamping portion 421 can be configured as a clamping rod, and the elastic member 41 can be configured as a spring. The spring is sleeved around the clamping rod. The clamping rod can guide the spring to prevent the spring from tilting during compression. It is understood that the spring can be replaced by an annular rubber pad, which is sleeved around the clamping rod.

[0034] In some embodiments of the present application, the radial length of the guide rod is smaller than the radial length of the clamping portion 421, so as to form a shoulder at the intersection of the guide rod and the clamping portion 421, and one end of the elastic member 41 is connected to the shoulder, and the other end is connected to the bottom wall of the accommodating groove 11, thereby fixing the elastic member 41.

[0035] The clamping portion 421 cooperates with the clamping groove 44 to achieve the limitation of the interface end 22 in the second direction a2 along the first direction. In some embodiments of the present application, the clamping portion 421 has a first limiting surface 4211, and the side wall of the clamping groove 44 is formed with a second limiting surface 441. When the second limiting structure 40 is in the first state and the first limiting surface 4211 abuts against the second limiting surface 441, the clamping portion 421 limits the movement of the interface end 22 in the second direction a2 in the first direction.

[0036] In some embodiments of the present application, the first limiting surface 4211 and the second limiting surface 441 are parallel to each other, and the first limiting surface 4211 is set at an angle b with the first direction a, where b is an acute angle or a right angle. It can be understood that when the angle between the first limiting surface 4211 and the first direction a is closer to 0°, it is difficult for the first limiting surface 4211 and the second limiting surface 441 to abut against each other to limit the movement of the interface end 22 in the first direction a1 of the first direction. In order to better abut and limit the first limiting surface 4211 and the second limiting surface 441, in some embodiments of the present application, 60°≤a≤90°, for example, 65°, 70°, 75°, 80° or 85°, etc. Preferably, please refer to Figure 3 As shown, the first limiting surface 4211 and the second limiting surface 441 are perpendicular to the first direction a. After the first limiting surface 4211 abuts against the second limiting surface 441, the two can naturally limit the movement of the joint end along the second direction a2 of the first direction.

[0037] In some embodiments of the present application, the clamping portion 421 has an extrusion surface 4212, and an angle c is formed between the extrusion surface 4212 and the first direction a1 of the first direction, where c is an acute angle. When the interface end 22 slides along the first direction a1 of the first direction, it can extrude the extrusion surface 4212. The external force applied to the extrusion surface 4212 has a component force along the depth direction of the accommodating groove 11, which can force the limit member 42 to shrink into the accommodating cavity 11. It can be understood that the closer the angle between the extrusion surface 4212 and the first direction a1 of the first direction is to 90°, the smaller the component of the force along the depth direction of the accommodating groove 11 after the interface end 22 applies external force to the extrusion surface 4212, resulting in difficulty for the limiter 42 to shrink into the accommodating groove 11; the closer the angle between the extrusion surface 4212 and the first direction a1 of the first direction is to 0°, the greater the component of the force along the depth direction of the accommodating groove 11 of the external force applied by the interface end 22 to the extrusion surface 4212, resulting in easy shrinkage of the limiter 42 into the accommodating cavity 11. Therefore, when the angle c is within the range of greater than or equal to 20° and less than or equal to 70°, the user needs to apply a certain external force when pushing the interface end 22 to move along the first direction a1 of the first direction, and the user has a good feedback sense; and the interface end 22 can smoothly force the limiter 42 to shrink into the accommodating groove 11; preferably, 30°≤c≤60°, for example, 35°, 40°, 45°, 50° or 50°, etc.

[0038] In the embodiment of the present application, there is no limitation on whether the extrusion surface 4212 is a plane or an arc surface. Whether it is a plane or an arc surface, when the interface end 22 moves along the first direction a1 of the first direction, the interface end 22 applies an external force to the extrusion surface 4212, thereby causing the limiter 42 to retract into the accommodation cavity. To simplify the structure of the limiter 42, please refer to Figure 1 As shown, in the specific embodiment of the present application, the extrusion surface 4212 is configured as a plane.

[0039] In some embodiments of the present application, the extrusion surface 4212 is partially located in the receiving groove 11 or the bottom edge of the extrusion surface 4212 along the extension and contraction direction of the limiter 42 is flush with the side wall of the interface end 22 provided with the snap-fit ​​groove 44. When the interface end 22 slides in the first direction a1 in the first direction, the interface end 22 needs to contact the extrusion surface 4212 to apply external force to the extrusion surface 4212 to force the snap-fit ​​portion 421 to shrink into the receiving groove 11. The extrusion surface 4212 is partially located in the receiving groove 11 or the bottom edge of the extrusion surface 4212 along the extension and contraction direction of the limiter 42 is flush with the side wall of the interface end 22 provided with the snap-fit ​​groove 44. This ensures that the interface end 22 can contact the extrusion surface 4212 after entering the limiting groove 31 and sliding a certain distance in the first direction a1 in the first direction. Please refer to Figure 3 As shown, in the specific embodiment of the present application, the extrusion surface 4212 is partially located in the receiving groove 11, ensuring that the interface end 22 can contact the extrusion surface 4212 when moving in the first direction a1 in the first direction.

[0040] Please refer to Figure 3 As shown, in some embodiments of the present application, the second limiting structure 40 also includes a circumferential limiting member 4342, which is fixed in the accommodating groove 11. One of the circumferential limiting member 4342 and the guide portion 422 has a circumferential limiting groove 423, and the other is protruding with a circumferential limiting block 431. The circumferential limiting block 431 is in the circumferential limiting groove 423, and the gap between the bottom wall of the circumferential limiting groove 423 and the top wall of the circumferential limiting block 431 is greater than the depth of the snap-in groove 44 to avoid the movement trajectory of the limiting member 42 when the second limiting structure 40 switches from the first state to the second state.

[0041] The circumferential limiter 4342 is fixedly connected to the power supply body 10, and when the circumferential clamping portion 421 is in the circumferential clamping groove 44, it limits the rotation of the circumferential clamping portion 421 relative to the circumferential clamping groove 44, ensuring that the limiter 42 has a fixed posture, that is, ensuring that the first limiter surface 4211 and the extrusion surface 4212 of the limiter 42 are distributed along the first direction; because when the extrusion surface 4212 of the limiter 42 is subjected to external force, the limiter 42 will move along the depth direction of the accommodating groove 11, That is, the circumferential limit member 4342 will slide in the circumferential limit groove 423 along the depth direction of the circumferential limit groove 423. Therefore, the gap between the bottom wall of the circumferential limit groove 423 and the top wall of the circumferential limit block 431 is greater than the depth of the clamping groove 44, ensuring that the cooperation between the circumferential limit member 4342 and the circumferential limit groove 423 should not affect the sliding of the limit member 42 relative to the accommodating groove 11, and the second limit structure 40 avoids the movement trajectory of the limit member when switching from the first state to the second state.

[0042] Since the groove wall of the rear circumferential limit groove 423 cooperates with the circumferential limit member 4342 and the circumferential limit groove 423 to limit the rotation of the circumferential limit member 4342 in the circumferential limit groove 423, the cross-section of the circumferential limit member 4342 and the circumferential limit groove 423 perpendicular to the depth direction of the accommodating groove 11 should be non-circular, and the circumferential limit member 4342 can be configured as a prismatic or elliptical shape, etc., and the corresponding circumferential limit groove 423 can be configured as a prismatic cavity or an elliptical cavity.

[0043] In addition to the aforementioned provision of the circumferential limiting member 4342 and the circumferential limiting groove 423 to limit the rotation of the limiting member 42 relative to the circumferential limiting groove 423, in conjunction with the aforementioned configuration in which the clamping portion 421 is completely within the clamping groove 44, the guide portion 422 naturally slides in connection with the groove wall of the accommodating groove 11. In this case, the cross-section of the guide portion 422 and the accommodating groove 11 along a direction perpendicular to the depth of the accommodating groove 11 can be configured as a non-circular shape. In conjunction with the aforementioned configuration in which the guide portion 422 and / or the clamping portion 421 slides in connection with the groove wall of the accommodating groove 11 when the clamping portion 421 is within the clamping groove 44, in this case, the cross-section of the accommodating groove 11, the guide portion 422, and / or the clamping portion 421 along a direction perpendicular to the depth of the accommodating groove 11 can be configured as a non-circular shape.

[0044] Please refer to Figure 3 As shown, in some embodiments of the present application, the circumferential clamping portion 421 is fixed to one end of the guide portion 422 away from the clamping portion 421, and the circumferential clamping portion 421, the guide portion 422 and the clamping portion 421 are integrally formed; the circumferential clamping groove 44 is opened in the circumferential limiting member 4342.

[0045] Please refer to Figure 1 As shown, in some embodiments of the present application, the first limiting structure 30 includes a limiting groove 31 provided on the power supply body 10 and a limiting block 32 protruding from the groove wall of the limiting groove 31, the accommodating groove 11 is connected to the limiting groove 31, and when the second limiting structure 40 is in the first state, the interface end 22 is clamped between the bottom wall of the limiting groove 31 and the limiting member 42, and the interface end 22 is clamped between the opposite side walls of the limiting groove 31, and the interface end 22 moves along the first direction a1 of the first direction until the limiting block 32 is separated from the interface end 22, and the interface end 22 can fall out of the limiting groove 31.

[0046] When the interface end 22 is within the limiting groove 31, it is clamped between the bottom wall of the limiting groove 31 and the limiting member 42, thereby limiting the movement of the interface end 22 in the length direction of the power supply body 10. Furthermore, when the interface end 22 is within the limiting groove 31, it is clamped between the two opposite side walls of the limiting groove 31, thereby limiting the movement of the interface end 22 in the thickness direction of the power supply body 10. In view of the above-mentioned interface end 22 including an insulating portion and a power connection portion fixed to the insulating portion, and the clamping groove 44 being provided on the insulating portion, that is, the insulating portion cooperates with the first limiting structure 30 and the second limiting structure 40 to limit the movement of the interface end 22, it can be understood that the insulating portion abuts against the groove wall of the limiting groove 31 and the limiting portion to limit the interface end 22.

[0047] In the embodiment of the present application, there are two limit blocks 32 , which are located on two opposite side walls of the limit slot 31 , and there is sufficient spacing between the two limit members 42 for the data line 20 to pass through, so that the data line 20 can be taken out of the limit slot 31 .

[0048] Please refer to Figure 5 and Figure 6 As shown, in some embodiments of the present application, the mobile power supply also includes a clamping member 50 fixed to the power supply body 10, and a clamping gap 60 is formed between the clamping member 50 and the outer surface of the power supply body 10. The data cable 20 also includes a transmission line 23 body connected between the interface end 22 and the connection end 21. The transmission line 23 body can be clamped in the clamping gap 60, so that the transmission line 23 body portion forms a hanging rope, and the interface end 22 is connected to an external electronic device.

[0049] The transmission line 23 body is in the clamping gap 60 and is in frictional contact with the clamping part 50 and the outer surface of the power supply body 10, so that the clamping part 50 and the power supply body 10 can fix the transmission line 23 body. At this time, the transmission line 23 body from one end connected to the connection end 21 to the part clamped between the clamping part 50 and the power supply body 10 can be bent to form a lanyard for hanging or for the user to carry.
