[0001] This utility model relates to the field of new energy vehicle charging technology, and in particular to a power collector. Background Technology

[0002] With the increasing popularity of electric vehicles, the market demand for chargers used to charge new energy vehicles is constantly growing; and as a key component of vehicle charging, the performance and reliability of the charger are particularly important. Currently, a major challenge facing chargers in practical applications is their waterproof performance, which is crucial for ensuring their normal operation under various environmental conditions. Good waterproof performance not only extends the lifespan of the charger but also ensures the safety of the charging process. However, chargers often face heat dissipation issues; simply improving their waterproof performance will inevitably reduce their heat dissipation performance. Therefore, improving the waterproof performance of chargers while ensuring their heat dissipation is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0003] The purpose of this utility model is to provide a power collector that improves its waterproof performance while ensuring its heat dissipation performance.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] An energy collector, characterized in that it comprises a first housing and a second housing formed separately and enclosing each other; the first housing includes a first connecting portion and a mating portion, the first connecting portion having a plurality of vent holes spaced apart; the second housing has a second connecting portion formed thereon.

[0006] The power collector also includes a first rubber ring, which includes a sealing part and an adjusting part that are arranged around and integrally formed;

[0007] The second connecting part engages with the first connecting part via the sealing part; the adjusting part is disposed away from the second connecting part and is located between the engaging part and the second connecting part;

[0008] When the internal temperature of the first or second housing rises and the resulting air pressure becomes too high, hot air can pass through the vent hole, causing the adjustment part to move away from the mating part, so as to be discharged to the outside.

[0009] In one embodiment, the second housing further includes an abutment portion, which serves to limit the first connection portion when the second connection portion engages with the first connection portion via the sealing portion.

[0010] In one embodiment, the first connecting portion is further formed with an annular groove, the annular groove being used to fix the first rubber ring, and the depth of the annular groove being less than the cross-sectional width of the sealing portion.

[0011] In one embodiment, it further includes a second rubber ring and a light-transmitting housing; the second housing also has a light-transmitting hole.

[0012] The second housing has a mounting groove formed around the light-transmitting hole, the second rubber ring is fixed in the mounting groove, and the light-transmitting housing is sealed to the second rubber ring and the second housing in sequence by screws.

[0013] In one embodiment, a ventilation port is also formed on the side of the first housing opposite to the second housing, the ventilation port being used to connect a blower assembly.

[0014] In one embodiment, the ventilation interface is also connected to a backflow preventer, a temperature sensor is also provided inside the first housing, and the power source is also externally equipped with a blower assembly, which is connected to the ventilation interface through the backflow preventer.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This utility model's technical solution achieves both improved heat dissipation and enhanced waterproofing performance of the power source by incorporating vents and a first rubber ring. Specifically, the second connecting part mates with the first connecting part via the sealing part; the adjusting part is positioned away from the second connecting part and located between the mating part and the second connecting part. When the electronic components within the first or second housing continue to operate, the temperature may become excessively high, leading to an increase in air pressure within the first or second housing. When the air pressure reaches a preset value, hot air can pass through the vents, causing the adjusting part to move away from the mating part to expel heat from the outside, thereby achieving a heat dissipation effect.

[0028] To make the technical objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] In the description of this utility model, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component centrally located at the same time.

[0030] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0031] This utility model embodiment provides a power collector 100.

[0032] A typical new energy vehicle charging station includes a column, a power source 100, and a charging gun. The column is used to hang the power source 100 and the charging gun, and the charging gun and the power source 100 are connected by wires.

[0033] Please see Figures 1 to 5 In one embodiment of the present invention, the power collector 100 includes a first housing 110 and a second housing 120 that are separately formed and enclosed; the first housing 110 includes a first connecting part 111 and a mating part 112, the first connecting part 111 having a plurality of spaced ventilation holes 111a; the second housing 120 has a second connecting part 121.

[0034] The power collector 100 also includes a first rubber ring 130, which includes a sealing part 131 and an adjusting part 132 that are arranged around the device and integrally formed.

[0035] The second connecting part 121 engages with the first connecting part 111 via the sealing part 131; the adjusting part 132 is disposed away from the second connecting part 121 and is located between the engaging part 112 and the second connecting part 121.

[0036] When the internal temperature of the first housing 110 or the second housing 120 rises and the air pressure becomes too high, hot air can pass through the vent 111a, causing the adjustment part 132 to move away from the mating part 112, so as to be discharged to the outside.

[0037] It is understood that the present invention achieves both improved heat dissipation and enhanced waterproof performance of the power collector 100 by setting a vent 111a and a first rubber ring 130. Specifically, the second connecting part 121 cooperates with the first connecting part 111 through the sealing part 131; the adjusting part 132 is positioned away from the second connecting part 121 and located between the mating part 112 and the second connecting part 121. When the electronic devices inside the first housing 110 or the second housing 120 are continuously operating, the temperature may become too high, which will cause the air pressure inside the first housing 110 or the second housing 120 to rise. When the air pressure rises to a preset value, hot air can pass through the vent 111a, causing the adjusting part 132 to move away from the mating part 112 to expel the outside air, thereby achieving a heat dissipation effect. It is also understood that the first rubber ring 130 is made of flexible material, and after a certain amount of hot air is expelled, the adjusting part 132 can smoothly return to a sealed state, at which point the sealing level can reach IP65. Furthermore, even when air escapes through tiny gaps, its waterproof rating still reaches IP54, meeting the basic waterproof performance requirements.

[0038] For further information, please refer to [link / reference]. Figure 2 and Figure 3 The second housing 120 further includes an abutment portion 122, which serves to limit the first connecting portion 111 when the second connecting portion 121 engages with the first connecting portion 111 via the sealing portion 131. It is understood that the abutment portion 122 is primarily designed to ensure a reasonable gap between the mating portion 112 and the second connecting portion 121, thereby improving assembly efficiency.

[0039] Furthermore, the first connecting portion also has an annular groove 111b, which is used to fix the first rubber ring 130, and the depth of the annular groove 111b is less than the cross-sectional width of the sealing portion 131.

[0040] It is understood that the annular groove 111b can improve the sealing effect and ensure the reliability of the connection between the first housing 110 and the second housing 120.

[0041] In a specific embodiment of this utility model, the power collector 100 further includes a second rubber ring 140 and a light-transmitting housing 150; the second housing 120 also has a light-transmitting hole.

[0042] The second housing 120 has a mounting groove 120a formed around the light-transmitting hole, the second rubber ring 140 is fixed in the mounting groove 120a, and the light-transmitting housing 150 is sealed and connected to the second rubber ring 140 and the second housing 120 in sequence by screws.

[0043] It is understood that the power source 100 is typically also used to indicate the charging status of an electric vehicle via lights. Specifically, a light-emitting element is provided inside the second housing 120, which can scatter light through the light-transmitting housing 150. Therefore, the placement of the second rubber ring 140 and the mounting groove 120a, while ensuring the complete functionality of the power source 100, also guarantees the waterproof effect of the light-transmitting housing 150, further improving the reliability of the product.

[0044] In a preferred embodiment, please refer to Figure 2 The first housing 110 also has a ventilation port 113 on the side opposite to the second housing 120, which is used to connect a blower assembly (not shown).

[0045] It is understood that the ventilation port 113 is provided to assist in heat dissipation. Normally, the ventilation structure is also connected to a sealing cover (not shown).

[0046] In another embodiment, the ventilation interface 113 is also connected to a backflow preventer (not shown), the first housing 110 is also provided with a temperature sensor, and the power supply 100 is also externally provided with a blower assembly, which is connected to the ventilation interface 113 through the backflow preventer.

[0047] It is understood that the temperature sensor can provide feedback signals to the blower assembly. When the temperature inside the first housing 110 is too high, the blower assembly is activated and blows air into the first housing 110 through the anti-reverse device, thereby allowing hot air to be discharged from the vent 111a.

[0048] It should also be noted that the anti-reverse device can usually prevent hot air from flowing back and improve heat dissipation efficiency.

[0049] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
