[0002] With the rapid development of society, people are becoming more and more dependent on electronic products. As electronic products are becoming smaller and smaller in structure, the battery power of their own configuration is often not enough to use. For this reason, people have designed charging devices with external large-capacity rechargeable batteries. Currently, commonly used charging devices need to use data cables to connect to electronic products, but because the data cable is generally separate, it is separately set from the charging device. Therefore, in emergencies or special circumstances, people occasionally forget to bring the data cable, which makes the charging device unusable. Therefore, people have designed charging devices with built-in data cables.

[0003] However, existing charging devices with built-in data cables usually only fix and protect the main body of the data cable connector, but lack protection for the electrical connector. As a result, the electrical connector of the data cable may be deformed or damaged after long-term use, thereby affecting the use of the charging device and the user experience. Utility Model Content

[0008] In an embodiment of the present utility model, in the direction of the electrical connector towards the first limiting portion, there is a first gap between one end of the first limiting portion away from the electrical connector and the inner wall of the housing.

[0009] In an embodiment of the present utility model, the charging device further includes a second limiting portion, which is arranged inside the housing and abuts against the first elastic portion, and the second limiting portion is located between the fixing portion and the first limiting portion.

[0010] In an embodiment of the present utility model, the thickness of the first elastic portion is 0.5 - 5 mm.

[0027]

First Embodiment

[0028] In this embodiment, as Figures 1-4 shown, the embodiment of the present invention provides a charging device 1. The charging device 1 includes, for example: a housing 10, a connecting line 20, and an elastic component 30.

[0029] The charging device 1 is, for example, an existing charging device such as a power bank, a mobile power supply, etc.

[0030] Specifically, as Figures 1-4 shown, the connecting line 20 has a first end 21 and a second end 22. The first end 21 is connected to the housing 10. A through hole for the first end 21 to pass through is provided on the surface of the housing 10. The first end 21 passes through the through hole and is electrically connected to the circuit board inside the charging device 1. The second end 22 has an electrical connector 23. The electrical connector 23 is used to connect to external electronic devices such as mobile phones, laptop computers, wireless Bluetooth earphones, etc., and realizes the function of charging the external electronic devices through the electrical connector 23. The connecting line 20 is, for example, a data line in the prior art. The first end 21 and the second end 22 are, for example, both ends of the data line. The electrical connector 23 is, for example, the head part of the data line.

[0031] The elastic component 30 is disposed on the housing 10, and the electrical connector 23 is detachably connected to the elastic component 30. In this embodiment, the elastic component 30 can be disposed inside one end of the housing 10 close to the connecting line 20, or can be disposed on the surface of the housing 10. For example, a groove is provided on the surface of the housing, and the elastic component 30 is disposed in the groove.

[0032] Among them, the elastic component 30 includes, for example: a fixing portion 31 and a first elastic portion 32.

[0033] Specifically, as Figure 3 and Figure 4 shown, the fixing portion 31 is connected to the housing 10. In this embodiment, the fixing portion 31 can be arranged inside the housing 10. The housing 10 can, for example, include a first housing 11 and a second housing 12, and the first housing 11 and the second housing 12 are connected by snap connection. The fixing portion 31 can be connected to the inner wall of the first housing 11, or the fixing portion 31 is connected to the inner wall of the second housing 12. It can be set according to the actual situation whether the fixing portion 31 is connected to the first housing 11 or the fixing portion 31 is connected to the second housing 12. Specifically, it is not limited here. The fixing portion 31 is, for example, the bottom end portion of the elastic component 30, which is used to fix the elastic component 30 inside the housing 10 and increase the connection firmness of the elastic component 30.

[0034] The first elastic portion 32 is connected to the fixing portion 31. As Figure 3 shown, the first elastic portion 32 includes, for example, a straight section and a bent section. The fixing portion 31 is connected to the straight section, and the bent section is connected to the straight section. Such a setting is because a part of the structure of the electrical connector is larger in volume than the charging socket structure of the electronic device, which facilitates the insertion of the plug of the electrical connector into the elastic component 30. The first elastic portion 32 is, for example, an elastic wall. The first elastic portion 32 is provided to enable the electrical connector 23 to be more conveniently inserted into the elastic component 30 through the deformation ability of the first elastic portion 32. The other end of the first elastic portion 32 is, for example, formed with a hook structure. The other end of the first elastic portion 32 can move up and down under the deformation amount of the first elastic portion 32. When the electrical connector 23 is inserted into the first elastic portion 32, through the self-deformation of the first elastic portion 32, the other end of the first elastic portion 32 moves outward. At this time, the electrical connector 23 can be snapped into the first elastic portion 32. Then, through the deformation restoring force of the first elastic portion 32, the other end of the first elastic portion 32 is connected to the electrical connector 23. And at this time, due to the hook structure of the first elastic portion, the hook part is clamped with the electrical connector 23, so that the electrical connector 23 can be clamped in the first elastic portion 32. When it is necessary to pull out the electrical connector 23, by applying a greater force by the user, the first elastic portion 32 deforms, so that the other end of the first elastic portion 32 moves outward at this time, making the opening of the other end of the first elastic portion 32 larger. At this time, it is convenient to pull out the electrical connector 23. Then the other end of the first elastic portion 32 rebounds and returns to its original position. Through the setting of the first elastic portion 23, the fastening property of the elastic component 30 to the electrical connector 23 can be improved.

[0035] The utility model provides an elastic component 30 on the shell 10, and the elastic component 30 includes a first elastic part 32 and a fixing part 31. One end of the first elastic part 32 is fixedly connected to the fixing part 31, and the other end of the first elastic part 32 is detachably connected to the electrical connector 23 of the connecting line 20. Through the deformation of the first elastic part 32, the other end of the first elastic part 32 can be connected and separated from the electrical connector 23 through the deformation of the first elastic part 32, so that when the electrical connector 23 is inserted into the first elastic part 32, the electrical connector 23 is clamped in the first elastic part 32 through the deformation of the first elastic part 32. When the electrical connector 23 is used, the electrical connector 23 is pulled out from the other end of the first elastic part 32, and the electrical connector 23 is separated from the other end of the first elastic part 32 through the deformation of the first elastic part 32, so that the detachable connection between the first elastic part 32 and the electrical connector 23 is achieved, so that when the electrical connector 23 is not in use, the electrical connector 23 can be protected and clamped, thereby improving the service life of the charging device 1 and improving the user's sense of use and experience.

[0036] Furthermore, the elastic component 30 is disposed in the housing 10, and the elastic component 30 also includes a first limiting portion 33, which is protrudingly disposed on the side of the first elastic portion 32 away from the electrical connector 23 and connected to the first elastic portion 32. The first limiting portion 33 is, for example, a limiting rib, and the first limiting portion 33 is disposed on the outside of the first elastic portion 32. When the length of the first elastic portion 32 disposed in the housing 10 is relatively long, since the first elastic portion 32 has elasticity and deformation, when the length of the first elastic portion 32 is too long, it will increase the deformation of the first elastic portion 32, and the increase in deformation will not be able to clamp the electrical connector 23. Therefore, in order to reduce the deformation of the first elastic portion 32, the first limiting portion 33 is disposed on the outside of the first elastic portion 32, so that the first elastic portion 32 can only be deformed on the right side of the first limiting portion 33 (such as Figure 4 As shown in the figure, the deformation length of the first elastic portion 32 can be shortened by setting the first limiting portion 33, so that the deformation of the first elastic portion 32 is small, thereby making the elastic force of the first elastic portion 32 high, so that the clamping effect of the electrical connector 23 of the connecting line 20 is better.

[0037] Specifically, the housing 10 may include, for example, a first housing 11 and a second housing 12, the first housing 11 and the second housing 12 are connected, the first elastic portion 32 is disposed close to the first housing 11, the first housing 11 is, for example, an upper housing of the charging device 1 of this embodiment, and the second housing 12 is, for example, a lower housing of the charging device 1 of this embodiment. The first limiting portion 33 is disposed on a side of the first elastic portion 32 close to the first housing 11 and is connected to the first elastic portion 32.

[0038] Further, as Figure 3 and Figure 4 shown, the charging device 1 further includes, for example, a first clamping portion 41 and a second clamping portion 42 disposed opposite to the first clamping portion 41. The first clamping portion 41 is disposed at one end of the first elastic portion 32 away from the fixing portion 31, that is, the first clamping portion 41 is disposed at the top end of the first elastic portion 32. Both the first clamping portion 41 and the second clamping portion 42 are detachably connected to the electrical connector 23, and at least a part of the electrical connector 23 is located between the first clamping portion 41 and the second clamping portion 42. The first clamping portion 41 and the second clamping portion 42 are, for example, plastic buckles. Through the cooperation of the first clamping portion 41 and the second clamping portion 42, the electrical connector 23 can be pulled out and inserted into the elastic assembly 30. For example, the first elastic portion 32 can move up and down within the housing 10 of the power bank, so that the opening between the first clamping portion 41 and the second clamping portion 42 is enlarged or reduced (to achieve the insertion and removal of the electrical connector 23). In this embodiment, a first card slot corresponding to the first clamping portion 41 can be provided on one side of the electrical connector 23 connected to the first clamping portion 41, so that the first clamping portion 41 can be stuck in the first card slot. A second card slot corresponding to the second clamping portion 42 can be provided on one side of the electrical connector 23 connected to the second clamping portion 42, so that the second clamping portion 42 can be stuck in the second card slot. In this embodiment, the first elastic portion 32 is disposed near the first housing 11, then the first clamping portion 41 is also disposed near the first housing 11, and the second clamping portion 42 can be disposed on the corresponding inner wall of the second housing 12.

[0039] Further, along the direction of the electrical connector 23 towards the first limiting portion 33, there is a first gap 302 between the end of the first limiting portion 33 away from the electrical connector 23 and the inner wall of the housing 10. In this embodiment, there is a first gap 302 between the first limiting portion 33 and the inner wall of the first housing 11. Of course, in other embodiments, when the first elastic portion 32 is disposed near the second housing 12, a first interval 302 is formed between the first limiting portion 33 and the second housing 12, and specific details are not limited here.

[0040] In this embodiment, when there is a first gap 302 between the first limiting portion 33 and the inner wall of the first housing 11, and the first gap 302 is the gap formed between the first limiting portion 33 and the first housing 11. The first elastic portion 32 can move up and down within the range of the first gap 302. When the first limiting portion 33 comes into contact with the first housing 11, the deformation length of the first elastic portion 32 is limited to the right portion of the first limiting portion 33, and the clamping effect on the electrical connector 23 is improved by reducing the deformation amount of the first elastic portion 32. In addition, when there is a first gap 302, during the insertion and extraction of the electrical connector 23 into and out of the elastic component 30, the electrical connector 23 can be easily inserted into and extracted from the elastic component 30, thereby achieving a labor-saving effect and improving the user's sense of use and experience.

[0041] When the first limiting portion 33 abuts against the first housing 11, that is, when there is no first gap 302 between the first limiting portion 33 and the inner wall of the first housing 11: then, the first elastic portion 32 will only be able to deform on the right side of the first limiting portion 33. By setting the first limiting portion 33, the deformation length of the first elastic portion 32 can be reduced, the deformation amount of the first elastic portion 32 can be decreased, so that the elastic force of the first elastic portion 32 is high, and the clamping effect of the elastic component 30 on the electrical connector 23 is better.

[0042] In a preferred embodiment of this embodiment, as Figures 3-4 shown, when there is a first gap 302 between the first limiting portion 33 and the first housing 11, the charging device 1 of this embodiment further includes, for example, a second limiting portion 43. The second limiting portion 43 is disposed within the housing 10 and abuts against the first elastic portion 32, and the second limiting portion 43 is located between the fixing portion 31 and the first limiting portion 33. The second limiting portion 43 is, for example, a limiting post. By setting the second limiting portion 43 at an appropriate length position corresponding to the first elastic portion 32 within the housing 10, the length to the right of the second limiting portion 43 is the deformable length of the first elastic portion 32, thereby reducing the deformation amount of the first elastic portion 32 and improving the clamping effect of the elastic component 30 on the electrical connector 23. In this embodiment, the second limiting portion 43 is disposed on the left side of the first limiting portion 33 to further reduce the deformation amount of the first elastic portion 32.

[0043] In a preferred embodiment of this embodiment, the thickness of the first elastic portion 32 is 0.5 - 5 mm; for example, it is 0.5 mm, 3 mm or 5 mm. That is, by increasing the thickness of the first elastic portion 32, the deformation amount of the first elastic portion 32 can also be reduced, thereby improving the clamping effect of the elastic component 30 on the electrical connector 23.

[0044] Furthermore, as Figure 4As shown, a receiving space 301 is formed in the elastic component 30, and at least a part of the electrical connector 23 is received in the receiving space 301. Through the setting of the receiving space 301, and the first clamping portion 41 and the second clamping portion 42, at least a part of the electrical connector 23 can be clamped and fixed in the elastic component 30.

[0045] In a preferred embodiment of the present embodiment, as Figure 4 shown, the elastic component 30 further includes a second elastic portion 35. The second elastic portion 35 is disposed on the fixing portion 31 and near the second housing 12. The second elastic portion 35 is disposed opposite to the first elastic portion 32, and the receiving space 301 is formed between the first elastic portion 32 and the second elastic portion 35; the second clamping portion 42 is disposed on the second elastic portion 35. The second elastic portion 35 can be provided so that the elastic component 30 can improve the clamping effect on the electrical connector 23. The second elastic portion 35 is, for example, an elastic wall. In the present embodiment, the second elastic portion 35 and the first elastic portion 32 can be symmetrically disposed with respect to the central portion of the receiving space 301 in the elastic component 30, that is, as Figure 4 shown, the first elastic portion 32 and the second elastic portion 35 are symmetrically disposed up and down. Any one of the first elastic portion 32 and the second elastic portion 35 can be relatively fixed to the housing 10, and the other elastic portion of the first elastic portion 32 and the second elastic portion 35 can be movable relative to the housing 10, or it can be provided that both the first elastic portion 32 and the second elastic portion 35 can be movable relative to the housing, and specifically, it is not limited here.

[0046] Furthermore, the elastic component 30 further includes a third limiting portion 36. The third limiting portion 36 is disposed on the side of the second elastic portion 35 close to the second housing 12. The third limiting portion 36 can be, for example, a limiting rib, and its specific structure can refer to the relevant description of the first limiting portion 33 above, and will not be elaborated here specifically.

[0047] Furthermore, along the direction of the electrical connector 23 towards the third limiting portion 36, there is a second gap 303 between the end of the third limiting portion 36 away from the electrical connector 23 and the inner wall of the housing 10. Specifically, in the present embodiment, as Figure 4 shown, there is a second gap 303 between the third limiting portion 36 and the inner wall of the second housing 12, or the second elastic portion 34 abuts against the inner wall of the second housing 12.

[0048] In this embodiment, when there is a second gap 303 between the second limiting portion 36 and the inner wall of the second housing 12, and the second gap 303 is the gap formed between the second limiting portion 36 and the second housing 12. The second elastic portion 35 can move up and down within the range of the second gap 303. When the second limiting portion 36 comes into contact with the second housing 12, the deformation length of the second elastic portion 35 is limited to the right portion of the second limiting portion 36. By reducing the deformation amount of the second elastic portion 35, the clamping effect on the electrical connector 23 is improved. In addition, when there is a second gap 303, during the insertion and extraction of the electrical connector 23 into and out of the elastic component 30, the electrical connector 23 can be easily inserted into and extracted from the elastic component 30, thereby achieving a labor-saving effect and improving the user's sense of use and experience.

[0049] When the second limiting portion 36 abuts against the second housing 12, that is, there is no second gap 303 between the second limiting portion 36 and the inner wall of the second housing 12: then, the second elastic portion 35 will only be able to deform on the right side of the second limiting portion 36. By the setting of the second limiting portion 36, the deformation length of the second elastic portion 35 can be reduced, the deformation amount of the second elastic portion 35 can be decreased, so that the elastic force of the second elastic portion 35 is high, and the clamping effect of the elastic component 30 on the electrical connector 23 is better.

[0050] In this embodiment, the elastic component 30 can be arranged, for example, at the corner end of the charging device 1. That is, when the electrical connector 23 is arranged at the corner of the charging device 1, a clamping force is applied to the accommodation space 301 of the elastic component 30 in the thickness direction of the charging device through the elastic component 30, the first clamping portion 41 and the second clamping portion 42, so as to clamp the electrical connector 23. When the electrical connector 23 can be inserted into the middle position of the charging device 1, a clamping force is applied to the electrical connector 23 in the width direction of the charging device through the elastic component 30, the first clamping portion 41 and the second clamping portion 42, to realize the clamping function of the electrical connector 23.

[0051] In this embodiment, a notch is provided on the side of the elastic component 30 facing the housing 10, that is, a notch is provided on the side of the elastic component 30, which is convenient for the insertion and extraction of the electrical connector 23 and reduces the occupied space of the elastic component.

[0052]

Second Embodiment

[0053] In this embodiment, the charging device 1 is basically the same as the charging device in the first embodiment, and the difference lies in that: the elastic component 30 further includes a connecting portion 34.

[0054] Specifically, as Figures 5-6, the elastic component 30 further includes, for example, a connecting portion 34. The connecting portion 34 is disposed between the first elastic portion 32 and the second elastic portion 35 and on the side of the fixing portion 31 facing the accommodation space 30). The connecting portion 34 is respectively connected to the first elastic portion 32 and the second elastic portion 35. The connecting portion 34 is, for example, a rectangular hollow structure. By providing the connecting portion 34, the deformable lengths of the first elastic portion 32 and the second elastic portion 35 can be reduced, thereby enhancing the clamping effect of the elastic component 30 on the electrical connector 23.
