[0016] In order to make the purpose, technical solution and advantages of the utility model clearer, the following further describes the utility model in detail with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model, and are not used to limit the utility model.

[0017] The utility model provides a charger with a shock-absorbing function built into the vehicle body, which is mainly applied to the field of electric vehicles. Please refer to Figures 1-3The charger 1 includes a charging shell 11, a charging module 12, a shock absorbing module, a first and a second connecting member, and other elements that meet the normal operation of the structure, such as a wire, which can be used to electrically connect to an external power source to supply energy to the charging module 12 and store electrical energy. The bottom of the charging shell 11 is fixed to the charging cavity of the electric vehicle through a first connecting member 13, so that the charger 1 is built into the charging cavity of the electric vehicle. The bottom of the charging module 12 is suspended inside the charging shell 11 through a second connecting member 14 to enhance the stability of the charging module 12. The shock absorbing module includes a first shock absorbing member 15 and a second shock absorbing member 16. The first shock absorbing member 15 is arranged on the first connecting member after the charging shell 11 is connected to the first connecting member 13. 13 is arranged on the outer periphery, or is arranged between the bottom of the charging shell 11 and the bottom of the charging inner cavity of the electric vehicle, so as to realize the shock absorption of the charging shell 11, so that the charger 1 can be stably built into the charging inner cavity of the electric vehicle under bumpy road conditions. Secondly, the second shock absorbing member 16 is arranged on the outer periphery of the second connecting member 14 after the charging module 12 is connected to the second connecting member 14, or the second shock absorbing member 16 is arranged between the bottom of the charging module 12 and the bottom of the charging shell 11, so that the charging module 12 realizes secondary shock absorption, that is, the charging module 12 can be stably installed in the charging shell 11 under the dual action of the first shock absorbing member 15 and the second shock absorbing member 16, and will not be separated from the existing installation position, thereby ensuring the normal use of the charger 1.

[0018] In this embodiment, please refer to Figure 2 and Figure 3 In order to ensure that the charger 1 is more stably fixed in the charging cavity of the electric vehicle, a mounting plate 111 is provided at the bottom of the charging shell 11, and mounting holes 1111 are provided at the four corners of the mounting plate 111. The first connecting member 13 passes through the mounting holes 1111 and is connected to the bottom of the charging cavity of the electric vehicle, which means that the number of the first connecting member 13 and the mounting holes 1111 is corresponding. The above arrangement enables the mounting plate 111 to be fixed to the charging cavity of the electric vehicle and cannot be moved, thereby controlling the position of the charger 1 in the charging cavity of the electric vehicle.

[0019] Furthermore, in order to enhance the stability of the connection within the charging cavity of the electric vehicle of the charger 1, the first shock-absorbing member 15 includes a plurality of first shock-absorbing washers, one of which is sleeved on the outside of the first connecting member 13 and is located between the mounting plate 111 and the bottom of the charging cavity of the electric vehicle, and another first shock-absorbing washer is sleeved on the outside of the first connecting member 13 and is located on the top of the mounting plate 111, so that the mounting hole 1111 on the mounting plate 111 is restricted on the first connecting member 13 by the two first shock-absorbing washers, and the two first shock-absorbing washers have a shock-absorbing effect on the top and bottom of the mounting plate 111, thereby preventing the charger 1 from generating excessive vibration during the bumpy process.

[0020] In another embodiment, also to enhance the stability of the connection within the charging cavity of the charger 1 for the electric vehicle, the first shock-absorbing member 15 includes a first shock-absorbing pad. The first shock-absorbing pad is located between the mounting plate 111 and the bottom of the charging cavity of the electric vehicle. The top of the first shock-absorbing pad abuts against the bottom of the mounting plate 111, and the bottom abuts against the bottom of the charging cavity of the electric vehicle. Similarly, the first shock-absorbing pad plays a shock-absorbing role for the mounting plate 111, preventing the charger 1 from deviating from its established position.

[0021] Regarding the first connecting member 13, in this embodiment, the first connecting member 13 includes a first bolt. Of course, in other embodiments, the first connecting member 13 can also be a connecting column, as long as it can fix the mounting plate 111 to the bottom of the charging cavity of the electric vehicle and can also be provided with a corresponding shock-absorbing structure.

[0022] Regarding the charging module 12, the charging module 12 includes a charging circuit board 121. Connecting holes 1211 are provided at the four corners of the charging circuit board 121. Connecting shafts 112 into which the connecting holes 1211 are inserted are provided at the bottom inside the charging housing 11. A shaft hole is provided at the top of the connecting shaft 112 along the inner direction of the connecting shaft 112. The charging module 12 is fixed inside the charging housing 11 by being inserted and fixed to the shaft hole through the second connecting member 14, so that the charging module 12 can operate normally.

[0023] Substantially, in this embodiment, the charging module 12 further includes a charging protection component, a charging detection component, and an input-output conversion component. The charging protection component, the charging detection component, and the input-output conversion component are all provided on the charging circuit board 121. Among them, the charging protection component receives the temperature signal of the charging detection component and cuts off the main input circuit when the temperature exceeds the limit. The charging protection component also receives the voltage signal input by the charging detection component. When the output voltage is the same as the input voltage, it indicates that the battery pack installed in the electric vehicle is fully charged, and the output circuit and the input circuit are cut off at the same time. As for the charging detection component, it detects whether the input voltage on the power supply side is within the rated voltage range, detects the difference between the output DC voltage and the battery side voltage, and detects the temperature of the charger 1 during the charging process. Finally, the power input-output conversion component receives the input of the external AC power supply and converts the input AC power supply into a DC power supply with an appropriate voltage to charge the battery pack.

[0024] In this embodiment, please refer to Figure 2 and Figure 3In order to further stabilize the stability of the connection of the charging circuit substrate 121 inside the charging shell 11 and prevent the charging circuit substrate 121 from being separated from the predetermined position and affecting the operation of the charger 1, a second shock absorbing member 16 is also provided inside the charging shell 11. The second shock absorbing member 16 includes a plurality of second shock absorbing washers, one of which is sleeved on the outside of the second connecting member 14 and is located between the charging circuit substrate 121 and the bottom of the charging shell 11, and another second shock absorbing washer is sleeved on the outside of the second connecting member 14 and is located on the top of the charging circuit substrate 121, so that the connecting hole 1211 is limited between the two second shock absorbing washers. The two second shock absorbing washers have a shock absorbing effect on the top and bottom of the connecting plate to prevent the charging circuit substrate 121 from generating excessive vibration during the bumping process.

[0025] In another embodiment, the second shock absorbing member 16 includes a second shock absorbing pad, which is located between the charging circuit substrate 121 and the bottom of the charging shell 11. The top of the second shock absorbing pad abuts against the bottom of the charging circuit substrate 121, and the bottom abuts against the bottom of the charging shell 11. When the charging circuit substrate 121 is subjected to external bumps, the vibration is reduced due to the second shock absorbing pad, thereby preventing the charging circuit substrate 121 from moving away from a predetermined position.

[0026] As for the second connecting member 14, in this embodiment, the second connecting member 14 includes a second bolt. Of course, in other embodiments, the second connecting member 14 can also be a connecting column, as long as it can fix the charging circuit substrate 121 to the bottom of the charging shell 11 and a corresponding shock absorbing structure can be provided.

[0027] From the foregoing, it can be seen that the charging module 12 is doubly affected by the first shock absorber 15 and the second shock absorber 16, that is, the first shock absorber 15 and the second shock absorber 16 play a dual shock absorbing role on the charging module 12, further enhancing the stability of the charging module 12 inside the charging shell 11, and ensuring that the charger 1 can be installed on the electric vehicle for use.

[0028] In this embodiment, the charger 1 also includes insulating oil, wherein an oil filling port 113 and a sealing plug for blocking / opening the oil filling port 113 are provided at the top of the charging shell 11. The insulating oil enters the charging shell 11 through the oil filling port 113, and the insulating oil immerses the charging circuit substrate 121, and then the sealing plug blocks the oil filling port 113. This arrangement reduces the cooling fan component, simplifies the internal structure of the charger 1, reduces the volume of the charger 1, reduces the cost of the charger 1, and at the same time enhances the insulation performance and heat dissipation performance of the charger 1, thereby improving the charging efficiency of the charger 1.

[0029] The specific embodiments of the present utility model described above do not constitute a limitation on the protection scope of the present utility model. Any other corresponding changes and deformations made according to the technical concept of the present utility model shall be included within the protection scope of the claims of the present utility model.
