Description

Technical Field

[0001] The invention relates to the technical field of electric vehicle chargers, in particular to an electric bicycle charger with high safety performance. Background Art

[0002] The working principle of the electric bicycle charger is to convert the AC 220V voltage into a DC voltage for charging the battery. The charger contains key components such as fuses, rectifier circuits, filter capacitors, switch field effect transistors, switch transformers, and switch oscillation integrated circuits. The AC first passes through the rectifier and filter circuit to output a DC +300V voltage, and then this voltage is sent to the switch oscillation circuit. The switch oscillation integrated circuit outputs a PWM signal to control the switch field effect transistor to work in a pulse oscillation state, and then outputs a pulse signal through the switch transformer. Finally, after passing through the output rectifier circuit, the power supply voltage is output.

[0003] When the heat dissipation holes of the charger are blocked by dust, it will cause abnormal charging or even fire. The reason is that, first of all, the charger will generate a lot of heat when working, and the role of the heat dissipation holes is to help dissipate this heat and keep the internal temperature of the charger within a safe range. The blocked holes will cause the heat to not be dissipated effectively, causing the internal temperature of the charger to rise. Long-term overheating may damage the electronic components inside the charger and may even cause a short circuit. Secondly, dust may become a conductor when it encounters water vapor, which will increase the risk of short circuit in the internal circuit of the charger. At the very least, it will cause the charger itself to be scrapped. In severe cases, it may ignite surrounding combustibles due to local overheating, causing a fire. Summary of the invention

[0004] In view of the problems existing in the prior art, the present invention is proposed.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: an electric bicycle charger with high safety performance, comprising: a load-bearing component, including a bottom frame, a heat sink arranged outside the bottom frame, and an interface arranged on the outer wall of the bottom frame; and a protective component, including a top frame movably connected to the bottom frame and side wing panels arranged outside the top frame for shielding the interface.

[0006] As a preferred solution of the electric bicycle charger with high safety performance described in the present invention, an elastic member is arranged in the bottom frame, and the elastic member is connected to the top frame at one end away from the bottom frame.

[0015] Beneficial effects of the present invention: The present invention provides a movable top frame and bottom frame to cooperate with each other to complete the charging task.

[0021] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and 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.

[0023] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0024] Example 1, reference Figures 1 to 4 , which is the first embodiment of the present invention.

[0025] Specifically, the carrier assembly 100 includes a bottom frame 101, a heat sink 101a disposed outside the bottom frame 101, and an interface 102 disposed on the outer wall of the bottom frame 101; wherein, heat dissipation holes are penetrated through the heat sink 101a for air circulation of the bottom frame 101, and the bottom frame 101 is provided with a plurality of electronic components for meeting charging needs (the prior art has been fully recorded and will not be elaborated on here).

[0026] The protection assembly 200 includes a top frame 201 movably connected to the bottom frame 101 and side wing plates 202 disposed outside the top frame 201 for shielding the interface 102. When the top frame 201 is located inside the bottom frame 101, the side wing plates 202 will block the interface 102, and when the top frame 201 is lifted, the side wing plates 202 will move, thereby releasing the charging channel of the interface 102.

[0027] Furthermore, when the top frame 201 is inside the bottom frame 101 , the top frame 201 will shield the heat sink 101 a to prevent moisture from entering.

[0028] Example 2, reference Figures 1 to 4 , which is the second embodiment of the present invention.

[0029] Specifically, an elastic member is provided in the bottom frame 101, and the elastic member is connected to the top frame 201 at one end away from the bottom frame 101. The elastic member is a compression spring, and when the top frame 201 is pressed into the bottom frame 101, the elastic member is deformed by force and provides a certain reset effect.

[0030] The outer wall of the top frame 201 is also integrally formed with a wiping plate 201a, and the wiping plate 201a is provided with a protrusion 201a-1 for wiping the heat sink 101a. The protrusion 201a-1 on the wiping plate 201a is made of rubber material and can be deformed to a certain extent.

[0031] The wiping plate 201a is provided with a limit hole 201b, and the outer wall of the bottom frame 101 is provided with a stud 103 movably connected to the limit hole 201b. When the stud 103 is rotated to the stud 103, the top frame 201 will be fixed in the bottom frame 101.

[0032] Example 3, reference Figures 1 to 4 , which is the third embodiment of the present invention.

[0033] Specifically, it also includes a fixing assembly 300, including a fixing column 301 installed under the bottom frame 101 by bolts and a suction cup 302 detachably connected to the fixing column 301. The fixing assembly 300 will further optimize the overall stability of the charger, and avoid the charger being ignored and piled up with other items during use, thereby affecting its overall heat dissipation effect.

[0034] The outer wall of the fixed column 301 is provided with a connecting channel 301a, and the end surface of the suction cup 302 is provided with an insertion rod 302a. The outer wall of the insertion rod 302a is provided with a fixing block 302a-1 movably connected to the connecting channel 301a. When the insertion rod 302a is inserted into the fixed column 301, the fixing block 302a-1 will be slidably connected with the connecting channel 301a, otherwise, the insertion rod 302a will not be able to be inserted into the fixed column 301.

[0035] The outer wall of the fixed column 301 is sleeved with a stop ring 301b, and the inner wall of the stop ring 301b is provided with an insertion channel 301b-2. During the above insertion process, the stop ring 301b needs to be rotated so that the insertion channel 301b-2 corresponds to the fixed block 302a-1, otherwise the insertion rod 302a will not be able to be inserted into the fixed column 301.

[0036] The outer wall of the limiting ring 301b is provided with a positioning through hole 301b-1. The inner wall of the limiting ring 301b is provided with an internal thread groove, and the outer wall of the fixing column 301 is provided with an external thread groove that is threadably matched with the internal thread groove.

[0037] When the fixing block 302a-1 passes through the insertion channel 301b-2 of the limiting ring 301b, the limiting ring 301b is rotated so that the positioning through hole 301b-1 contacts the fixing block 302a-1, thereby fixing the insertion rod 302a. It should be noted that when the insertion rod 302a is inserted into the fixing column 301, a spring should also be provided. During the insertion of the insertion rod 302a, the spring is deformed, which makes the positioning through hole 301b-1 better fix the fixing block 302a-1.

[0038] Importantly, it should be noted that the construction and arrangement of the present application shown in a plurality of different exemplary embodiments are only exemplary. Although only a few embodiments are described in detail in this disclosure, it should be readily understood by those who refer to this disclosure that many modifications are possible (e.g., the size, scale, structure, shape and proportion of various elements, and parameter values ​​(e.g., temperature, pressure, etc.), installation arrangement, use of materials, color, directional changes, etc.) without substantially departing from the novel teachings and advantages of the subject matter described in the application. For example, the element shown as integrally formed can be composed of multiple parts or elements, the position of the element can be inverted or otherwise changed, and the nature or number or position of the discrete element can be changed or changed. Therefore, all such modifications are intended to be included in the scope of the present invention.
