Description

Technical Field

[0001] The utility model relates to the technical field of mobile phone chargers, in particular to a mobile phone charger which is drop-proof and automatically powers off. Background Art

[0002] A self-power-off mobile phone charger is a charging device that can automatically stop supplying power when it detects that the mobile phone battery is fully charged. The self-power-off mobile phone charger monitors the charging status through an internal chip or circuit. When it determines that the battery is fully charged, it automatically cuts off the power supply to prevent overcharging.

[0003] However, it still has the following disadvantages in actual use:

[0004] Existing self-powering mobile phone chargers can prevent the mobile phone charger from accidentally falling and causing damage by wrapping the surface with a protective pad. However, since one end of the charger needs to be completely in contact with the socket, this end cannot be effectively protected. When the charger is subjected to impact force, the chance of damage to the charger increases. Utility Model Content

[0005] The purpose of the present utility model is to provide a mobile phone charger with an anti-drop function and automatic power-off function, so as to solve the problem raised in the above-mentioned background technology. The existing mobile phone charger with automatic power-off function can prevent the mobile phone charger from accidentally falling and causing damage by wrapping the surface with a protective pad. However, since one end of the charger needs to be completely in contact with the socket, the one end of the charger cannot be effectively protected, and when the charger is subjected to impact force, the chance of damage to the charger is increased.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The utility model is a mobile phone charger that is drop-proof and automatically powers off, comprising:

[0008] Charger body;

[0009] A protective assembly, comprising protective pads fixed to the upper and lower surfaces of the charger body;

[0010] The movable component includes a movable groove opened inside one side of both ends of the protective pad, a movable block slidably connected to the inside of the movable groove, a connecting column fixed on the upper surface of the movable block, a movable pad fixed on the upper surface of the connecting column, and connecting holes opened at equal intervals inside the movable pad.

[0011] Furthermore, a limiting column is fixed on the outer surface of the connecting column, a positioning column is fixed on the outer surface of the protective pad, and guide holes are provided inside the limiting column and the positioning column.

[0012] Furthermore, a connecting line is fixed inside the limiting column, and a counterweight ball is fixed on the bottom surface of the connecting line;

[0013] The diameter of the counterweight ball is smaller than the diameter of the guide hole.

[0014] Furthermore, ventilation holes are opened at equal intervals inside the protective pad, a first connecting plate is fixed to the lower surface of the top protective pad, and a second connecting plate is sleeved on the lower end of the first connecting plate.

[0015] Furthermore, a protrusion is fixed on the upper surface of the second connecting plate, and the protrusion is located inside the bottom end of the first connecting plate.

[0016] Furthermore, the protrusion is movably connected to a limit rod inside, and the limit block is fixed to one side surface of the limit rod;

[0017] The surface of the limiting block is in contact with the surface of one side of the first connecting plate.

[0018] Furthermore, a connecting sleeve is sleeved on the other side surface of the limiting rod, and a silicone belt is fixed on one end surface of the connecting sleeve;

[0019] The top surface of the silicone tape is in contact with the other side surface of the first connecting plate.

[0020] Compared with the prior art, the advantages of the present invention are:

[0021] 1. In the present invention, the movable pad and the movable block are used in conjunction. The fixed position of the movable pad can be changed by moving the movable block within the movable groove. When the charger is not in use, the movable pad can be moved to one end of the movable groove, so that one end of the charger is covered. This solution provides more comprehensive protection for the charger body and reduces the chance of damage when the charger is hit.

[0022] 2. Based on the first beneficial effect, with the coordinated use of the first connecting plate and the second connecting plate, the two sets of protective pads can be quickly connected together, and one end of the protective pad is longer than the length of the charger body. When the charger is hit, the charger body will not directly contact the ground. This solution can quickly fix the protective pad on the surface of the charger body, making it easy to replace the protective pad.

[0023] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0034] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0035] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0036] See also Figure 1-Figure 3 As shown, this embodiment is a mobile phone charger that is drop-proof and automatically powers off, comprising:

[0037] Charger main body 11;

[0038] A protective assembly, comprising protective pads 21 fixed to the upper and lower surfaces of the charger body 11;

[0039] The movable assembly includes movable grooves 33 provided on one side of each end of the protective pad 21, movable blocks 34 slidably connected to the movable grooves 33, connecting posts 35 fixed to the upper surface of the movable blocks 34, movable pads 31 fixed to the upper surface of the connecting posts 35, and connecting holes 32 equidistantly provided in the movable pads 31.

[0040] A limiting post 36 is fixed to the outer surface of the connecting post 35, and a positioning post 37 is fixed to the outer surface of the protective pad 21. A guide hole 38 is formed inside the limiting post 36 and the positioning post 37.

[0041] By adjusting the limiting column 36 and the positioning column 37 to the desired horizontal position, the connecting wire 39 can be passed through the guide hole 38. The guide hole 38 is used to receive and install the connecting wire 39.

[0042] A connecting wire 39 is fixed inside the limiting column 36, and a counterweight ball 391 is fixed to the bottom surface of the connecting wire 39;

[0043] The diameter of the weight ball 391 is smaller than the diameter of the guide hole 38;

[0044] One end of the connecting wire 39 is fixed inside the limiting column 36, and the other end is fixed inside the positioning column 37, so that the two movable blocks 34 are fixed in the desired position;

[0045] When protecting the charger body 11;

[0046] Applying a pushing force to the movable pad 31 causes the movable block 34 to move to one end of the movable groove 33. After the movable pad 31 covers the charger body 11, one end of the connecting wire 39 is passed through the guide hole 38 and fixed to one end of the limit column 36. Then, the counterweight ball 391 is passed through the inside of the guide hole 38 and the connecting wire 39 is fixed to the inside of the positioning column 37. When the charger body 11 is subjected to the force of the impact, the connecting hole 32 can cause the movable pad 31 to deform, thereby protecting the charger body 11.

[0047] When using the charger body 11;

[0048] First, remove one end of the connecting wire 39 from the interior of the positioning post 37, apply a pushing force to the movable pad 31, so that the movable block 34 moves to the other end of the movable groove 33, aligning the limit post 36 with the positioning post 37, and then pass the counterweight ball 391 through the interior of the guide hole 38 to fix the connecting wire 39 to the interior of the positioning post 37;

[0049] This step allows the charger body 11 to be more fully protected, and reduces the chance of damage when the charger is hit.

[0050] See also Figure 1 and Figure 4 As shown, this embodiment is based on the above embodiment 1 and also includes:

[0051] The protective pad 21 has equidistant ventilation holes 22 formed inside. A first connecting plate 23 is fixed to the lower surface of the top protective pad 21 , and a second connecting plate 24 is sleeved on the lower end of the first connecting plate 23 .

[0052] The vent holes 22 allow the protective pad 21 to deform, thereby improving the protection performance of the charger body 11. The first connecting plate 23 receives and installs the protective pad 21, and then receives and installs the second connecting plate 24.

[0053] A protrusion 25 is fixed on the upper surface of the second connecting plate 24, and the protrusion 25 is located inside the bottom end of the first connecting plate 23;

[0054] The provided protrusion 25 is used to receive and install the first connecting plate 23;

[0055] The protrusion 25 is internally movably connected to a limit rod 27, and a limit block 26 is fixed to one side surface of the limit rod 27;

[0056] The surface of the limit block 26 is in contact with the surface of one side of the first connecting plate 23;

[0057] The limiting rod 27 is used to connect the first connecting plate 23 and the second connecting plate 24 together, and the limiting block 26 is used to limit the limiting rod 27 to the inside of the first connecting plate 23;

[0058] A connecting sleeve 28 is sleeved on the other side of the limiting rod 27, and a silicone tape 29 is fixed on one end of the connecting sleeve 28;

[0059] The top surface of the silicone tape 29 is in contact with the other side surface of the first connecting plate 23;

[0060] The connecting sleeve 28 is used to limit the other side of the limiting rod 27. The silicone belt 29 is used to support and install the connecting sleeve 28, and then to support and install the first connecting plate 23. The silicone belt 29 is elastic, so it is easy to remove the connecting sleeve 28 from the limiting rod 27.

[0061] When installing the protective pad 21;

[0062] First, place one set of protective pads 21 into one end of the charger body 11, aligning the protrusions 25 with the inside of the first connecting plate 23. Place the other set of protective pads 21 into the other end of the charger body 11. Apply inward force to both sets of protective pads 21, inserting the protrusions 25 into the inside of the first connecting plate 23. Then, pass the limiting rod 27 through the inside of the protrusions 25, ensuring that the limiting block 26 is in contact with the first connecting plate 23. Finally, insert the connecting sleeve 28 into the limiting rod 27.

[0063] When removing the protective pad 21;

[0064] Under the elastic action of the silicone tape 29, after the connecting sleeve 28 is pulled out from one side of the limiting rod 27, a pulling force is applied to the limiting block 26. After the limiting rod 27 is pulled out from the inside of the protrusion 25, a force in the opposite direction is applied to the protective pad 21.

[0065] In this step, the protective pad 21 can be quickly fixed to the surface of the charger body 11, making it convenient to replace the protective pad 21.
