[0046] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals indicate the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.

[0047] Next, refer to Figures 1-10Describe a charging stand according to an embodiment of the present invention.

[0048] As shown in the figure, the charging stand 1 according to the present invention includes a housing 11. The housing 11 includes a bottom for supporting the charging stand 1 to stand and a top disposed opposite to the bottom. An accommodation space for accommodating electrical components is provided inside the housing 11. The charging stand 1 according to the present invention can be configured as a vertical design. The charging stand 1 is generally arranged vertically in the working state. Electrical components are accommodated in the housing 11. During the operation of the charging stand 1, a large amount of heat will be generated by the electrical components. Therefore, heat dissipation needs to be carried out through the air circulation channels provided on the wall thickness of the housing 11. Considering the more severe environment when the charging stand 1 works outdoors, the openings of the air circulation channels need to be restricted in the present invention.

[0049] In the related art, in order to obtain better heat dissipation efficiency, the openings of the air circulation channels are generally open on both the upper and lower sides in the extending direction of the housing 11. When the air circulation channels are open on both the upper and lower sides, it results in insufficient sealing effect of the charging stand 1 during outdoor operation. Rain, snow, dust, foreign objects, etc. are likely to enter the inside of the housing 11, affecting the service life of the charging stand 1.

[0050] For the charging stand 1 according to the present invention, the housing 11 is provided with a plurality of air circulation channels penetrating the wall thickness of the housing 11. The air circulation channels have a first opening 101 communicating with the accommodation space and a second opening 102 communicating with the external space. The first opening 101 is closer to the top than the second opening 102.

[0051] In the present invention, the first opening 101 and the second opening 102 are at least partially misaligned in the standing direction. In one embodiment, the first opening 101 and the second opening 102 are completely misaligned; in another alternative embodiment, the first opening 101 and the second opening 102 are partially misaligned. The situation where the first opening 101 is closer to the top of the housing 11 than the second opening 102 includes that the highest point of the first opening 101 is closer to the top of the housing 11 than the highest point of the second opening 102. In the air circulation channels, the airflow or foreign objects moving towards the accommodation space will inevitably have a tendency to move upwards. Under the action of gravity, foreign objects such as rain and snow cannot move upwards smoothly and are blocked outside the air circulation channels and cannot enter the inside of the accommodation space. Thus, when the charging stand 1 has a good heat dissipation effect, the charging stand 1 can still maintain a good waterproof and dustproof effect during outdoor work, extending the service life of the charging stand 1 and improving the stability of the charging stand 1.

[0052] According to an embodiment of the present invention, the housing 11 includes a relatively arranged front housing part and a rear housing part, and a side housing part located between the front housing part and the rear housing part. The front housing part is provided with a mating part 13 for connecting with a battery, and the air circulation channel is arranged in the side housing part.

[0053] The front housing part, the rear housing part and the side housing part can enclose the accommodation space for accommodating electrical components. The front housing part can be adapted to connect with a battery pack. By providing the mating part 13 on the front housing part, the connection between the charging base 1 and the battery can be made stable, ensuring the stable connection between the battery pack and the charging base 1.

[0054] The mating part 13 can include an electrical connection mating part 13a and a fixed connection mating part 13b. Among them, the electrical connection mating part 13a is adapted to electrically connect the battery pack with the electrical components in the charging base 1, and the fixed connection mating part 13b is adapted to contact and cooperate with the battery pack to ensure the relative position between the charging base 1 and the battery pack is stable during the charging process. During the charging process, the electrical connection mating part 13a electrically connects the battery pack with the electrical components inside the charging base 1, while the fixed connection part ensures the support of the battery pack, thus ensuring the relative position between the battery pack and the charging base 1 is stable.

[0055] According to an embodiment of the present invention, the housing 11 includes a first housing part 11a and a second housing part 11b connected to the first housing part 11a. The mating part 13 is located on the first housing part 11a, and the side housing part is located on the first housing part 11a and the second housing part 11b.

[0056] It should be noted here that the front housing part and the rear housing part can be understood as the front side wall and the rear side wall of the housing 11, or the front housing part and the rear housing part can be understood as side wall structures extending in the front or rear direction of the housing 11. This side wall structure can be constructed in any shape such as a flat plate or an arc, and the present invention does not limit this.

[0057] The front housing part and the rear housing part are connected through the side housing part. The front housing part needs to be connected with the battery pack, and the side housing part is connected between the front housing part and the rear housing part. Moreover, the side housing parts can be symmetrically arranged. By arranging the air circulation channel on the side housing part, air can enter the accommodation space from one side and flow out from the symmetric other side, so as to increase the air circulation speed in the housing and improve the heat dissipation effect of the charging base 1.

[0058] The housing 11 is configured with a first housing part 11a and a second housing part 11b. It can be understood that the first housing part 11a is the front shell and the second housing part 11b is the rear shell. The first housing part 11a is provided with a front part of the housing and part of the side part of the housing, and the second housing part 11b is provided with a rear part of the housing and part of the side part of the housing, so that the housing 11 is configured as a split structure, making the installation of the housing 11 convenient.

[0059] According to an embodiment of the present invention, the charging base 1 includes a plurality of waterproof parts 12. An air circulation channel is formed between adjacent two waterproof parts 12. The waterproof part 12 can be configured as a protrusion formed on the housing 11 and extending away from the housing 11. Adjacent two waterproof parts 12 are spaced apart to form an air circulation channel to communicate the accommodation space with the external space. The waterproof part 12 is on the housing 11, making the forming design of the air circulation channel easier. At the same time, it avoids the reduction of the structural strength of the housing 11 caused by forming an air circulation channel on the wall thickness of the housing 11. By setting the waterproof part 12, the structural stability of the housing 11 of the charging base 1 can be ensured, and at the same time, the waterproof and dustproof effect of the housing 11 is improved.

[0060] According to an embodiment of the present invention, the waterproof part 12 and the housing 11 are integrally formed, making the connection between the waterproof part 12 and the housing 11 more stable and reliable, improving the overall structural strength and reliability of the charging base 1, reducing the assembly procedure at the same time, and lowering the production cost of the charging base 1.

[0061] According to an embodiment of the present invention, the waterproof part 12 has a first extension part extending from the outside to the inside along the wall thickness of the housing 11, and a second extension part provided at the inner end of the first extension part and extending at an upward angle. The first extension part can extend in the horizontal direction, and the second extension part is provided at the inner end of the first extension part, and the second extension part can extend in the vertical direction. The second extension part can also have a certain inclination angle with the vertical direction.

[0062] The first extension part and the second extension part make the air circulation channel formed between adjacent two waterproof parts 12 have a part extending in the vertical direction and a part extending in the horizontal direction, forming multiple passages with different extending directions in the air circulation channel. The multiple passages with different extending directions can further avoid the probability of rain, snow, dust, etc. entering the interior of the accommodation space, improving the sealing performance of the charging base 1.

[0063] According to an embodiment of the present invention, among two adjacent waterproof parts 12, the first waterproof part is closer to the top of the housing 11 than the second waterproof part 12. The first waterproof part has a first side surface 121 facing the second waterproof part 12, and the second waterproof part 12 correspondingly has a second side surface 122 facing the first waterproof part. An air circulation channel is formed between the first side surface 121 and the second side surface 122.

[0064] The first waterproof part and the second waterproof part 12 can be arranged at intervals in the vertical direction. The surface of the first waterproof part facing the lower side is configured as the first side surface 121, and the surface of the second waterproof part 12 facing the upper side is configured as the second side surface 122. The air circulation channel is jointly formed among the first side surface 121, the second side surface 122, and the housing 11.

[0065] According to an embodiment of the present invention, the second side surface 122 includes, from outside to inside, a first lower straight surface, a second lower straight surface, and a third lower straight surface that are sequentially connected at an angle. The first lower straight surface extends obliquely from outside to inside and towards the top. The second lower straight surface is inclined towards the top in the horizontal direction. The outer end of the second lower straight surface is connected to the upper end of the first lower straight surface. The third lower straight surface is perpendicularly connected to the second lower straight surface.

[0066] The second side surface 122 can be configured as the upper surface of a waterproof part 12. The upper surface of the waterproof part 12 is formed with the first lower straight surface, the second lower straight surface, and the third lower straight surface connected in sequence. The first lower straight surface, the second lower straight surface, and the third lower straight surface are arranged at an angle, so that the air circulation channel has portions with different extending directions in the extending direction. The air circulation channel with multiple extending directions that are different does not hinder the air circulation, but can hinder rain, snow, dust, etc., reducing the probability of rain, snow, and dust entering the accommodation space, thereby improving the sealing effect of the charging base 1.

[0067] According to an embodiment of the present invention, the first side surface 121 includes, from outside to inside, a first upper straight surface, a curved surface, and a second upper straight surface that are sequentially connected. The first upper straight surface is parallel to the second upper straight surface, and the curved surface is concave towards the top of the housing 11; the gap between the first upper straight surface and the first lower straight surface is greater than the gap between the second lower straight surface and the second upper straight surface.

[0068] According to an embodiment of the present invention, the first upper straight surface and the second upper straight surface can extend in the horizontal direction. The curved surface is connected to the inner edge of the first upper straight surface facing the inside, and the curved surface is connected to the outer edge of the second upper straight surface facing the outside. The curved surface transitions between the first upper straight surface and the second upper straight surface, so that there is a good transition region in the air circulation channel, reducing the hindrance to air circulation, increasing the air circulation rate in the air circulation channel, and further improving the heat dissipation effect of the charging base 1.

[0069] According to an embodiment of the present invention, the cross-sectional area of the air flow channel gradually decreases from the outside to the inside along the wall thickness of the housing 11. Constructing the air flow channel into a structure with a gradually decreasing cross-sectional area from the outside to the inside can increase the air flow rate in the air flow channel by reducing the cross-sectional area. When the air flow rate is constant, reducing the cross-sectional area of the air flow channel can increase the air flow velocity, so that the gas in the air flow channel flows at a higher rate, thereby improving the heat dissipation effect of the charging base 1.

[0070] The charging base 1 according to another embodiment of the present invention will be briefly described below.

[0071] The charging base 1 according to the present invention includes a housing 11. The housing 11 includes a bottom for supporting the charging base 1 to stand and a top opposite to the bottom. An accommodation space for accommodating electrical components is provided inside the housing 11. The housing 11 includes a front housing part and a rear housing part arranged opposite to each other, and a side housing part located between the front housing part and the rear housing part. A mating part 13 for connecting with a battery pack is provided on the front housing part. The mating part 13 includes a pole base body 131. The pole base body 131 has a support surface 131a, a plurality of bosses 133 extending from the support surface 131a towards the top of the housing 11, and electrode plates 132 extending from the top surface 133a of the bosses 133 towards the top of the housing 11. The support surface 131a is inclined from the outside to the inside along the wall thickness of the housing 11 towards the top of the housing 11, and the top surface 133a of the bosses 133 is higher than the support surface 131a.

[0072] The electrical connection mating part 13a of the mating part 13 may include a pole base body 131. The pole base body 131 has a support surface 131a. A plurality of bosses 133 extending towards the top of the housing 11 are provided on the support surface 131a. The pole base body 131 serves as the base of the electrical connection mating part 13a. A support surface 131a is provided on the pole base body 131. The support surface 131a may be the upper surface of the pole base body 131. A plurality of bosses 133 may be provided on the upper surface of the pole base body 131. An electrode plate 132 protrudes from the top surface 133a of each boss 133. The provision of the bosses 133 can protect the electrode plates 132. When rainwater covers the support surface 131a, the roots of the plurality of electrode plates 132 can be spaced apart, preventing the roots of the electrode plates 132 from being on the same horizontal plane as the support surface 131a.

[0073] The supporting surface 131a is inclined from the outside to the inside along the wall thickness of the housing 11 towards the top of the housing 11, and the top surface 133a of the boss 133 is higher than the supporting surface 131a. With such a setting of the pole seat body 131, when rainwater drips onto the supporting surface 131a, it will slide down along the slope of the supporting surface 131a. Even if a certain amount of rainwater covers the supporting surface 131a, since the top surface 133a of the boss 133 is higher than the supporting surface 131a, the accumulated amount of rainwater cannot exceed the top surface 133a of the boss 133, thereby avoiding short - circuiting between the electrode plates 132 due to the accumulation of rainwater and preventing safety accidents, improving the safety of the charging base 1.

[0074] According to an embodiment of the present invention, a partition 134 extending along the arrangement direction of the electrode plates 132 is provided inside the pole seat body 131. The partition 134 abuts against the supporting surface 131a and the upper edge of the partition 134 is higher than the supporting surface 131a. Waterproof grooves 1341 extending along the standing direction are respectively provided on both sides of the partition 134 on the supporting surface 131a. The upper edge and the left - and - right edges of the partition 134 all extend beyond the pole seat body 131 to limit the relative position between the mating portion 13 and the housing 11, ensuring the stable fit between the mating portion 13 and the housing 11.

[0075] Waterproof grooves 1341 are respectively provided on both sides of the partition 134, and protrusions cooperating with the waterproof grooves 1341 are provided on the housing 11. After the waterproof grooves 1341 cooperate with the waterproof protrusions, the sealing gap between the partition 134 and the housing 11 is extended, so as to improve the sealing effect between the partition 134 and the housing 11, and prevent rainwater and the like from entering the accommodation space through the gap between the partition 134 and the housing 11.

[0076] According to an embodiment of the present invention, a demolding hole 113 is provided on the first housing portion 11a, and a baffle 14 is further provided in the charging base 1. The baffle 14 is formed with a protrusion suitable for plugging the demolding hole 113 to improve the sealing effect of the charging base 1. At the same time, the baffle 14 can also squeeze the mating portion 13 when the first housing portion 11a and the second housing portion 11b are installed, ensuring the proper installation of the mating portion 13 and improving the stability of the mating portion 13.

[0077] According to an embodiment, the charging base 1 includes a housing 11. An accommodation space for accommodating electrical components is provided inside the housing 11, and a heat - dissipation area 15 suitable for dissipating heat from the electrical components is formed on the outer surface of the housing 11. A recessed portion 11c is provided on the housing 11. The recessed portion 11c includes a bottom wall 11c1 and side walls extending upward from the bottom wall 11c1. The heat - dissipation area 15 is provided on the bottom wall 11c1 and / or the side walls of the recessed portion 11c. The heat - dissipation area 15 includes a plurality of heat - dissipation holes 151 communicating with the accommodation space and the external space.

[0078] The charging base 1 of the present invention can be installed outdoors. The electrical components in the housing 11 generate heat during operation. To ensure the reliability of the charging base 1 and prevent it from overheating, a heat dissipation area 15 for dissipating heat from the electrical components is formed on the outer surface of the housing 11. The heat dissipation area 15 can conduct the heat generated by the electrical components in the housing 11, thereby preventing excessive heat accumulation in the housing 11 and improving the reliability of the charging base 1.

[0079] A recess 11c is provided on the housing 11. The recess 11c may include a bottom wall 11c1 and side walls provided on the outer periphery of the bottom wall 11c1 and extending away from the bottom wall 11c1. The heat dissipation area 15 may be provided on the bottom wall 11c1 or / and the side walls of the recess 11c. Providing the recess 11c on the housing 11 and setting the heat dissipation area 15 on the bottom wall 11c1 or / and the side walls is suitable for preventing rainwater from entering the interior of the housing 11 through the heat dissipation area 15 in rainy or snowy weather.

[0080] During rainfall or snowfall, setting the heat dissipation area 15 on the bottom wall 11c1 or / and the side walls of the recess 11c makes it necessary for rain or snow to meet a certain inclination angle before it may enter the recess 11c, and it is more difficult to come into contact with the bottom wall 11c1 or the side walls in the recess 11c. By setting the heat dissipation area 15 on the bottom wall 11c1 or / and the side walls of the recess 11c, the present application improves the rain and snow resistance of the charging base 1 and its reliability.

[0081] According to the charging base 1 of the present invention, a recess 11c is provided on the outer surface of the housing 11, and the heat dissipation area is set on the bottom wall 11c1 or / and the side walls 11c1 of the recess 11c, so that while the charging base 1 maintains a good heat dissipation effect, it also has good rain and snow resistance, thereby improving the safety and service life of the charging base 1.

[0082] According to an embodiment of the present invention, the recess 11c includes a bottom wall 11c1 and an upper side wall 11c2 provided on the upper edge of the bottom wall 11c1, and the heat dissipation area 15 is provided on the bottom wall 11c1 of the recess 11c.

[0083] In an embodiment of the present invention, the charging base 1 can be set up to stand, the recessed portion 11c is arranged in the circumferential direction of the housing 11 and recesses towards the inner side of the housing 11. The opening of the recessed portion 11c can be open towards the horizontal direction. The bottom wall 11c1 of the recessed portion 11c can extend in the vertical direction, and the side wall of the recessed portion 11c is arranged on the outer periphery of the bottom wall 11c1 and extends towards the direction away from the inner side of the housing 11. In the side wall, there is an upper side wall 11c2 close to the top of the housing 11 and a lower side wall close to the bottom of the housing 11. The upper side wall 11c2 and the lower side wall can be arranged opposite to each other, as well as a first side wall and a second side wall connecting the upper side wall 11c2 and the lower side wall.

[0084] The heat dissipation area 15 can be arranged on the bottom wall 11c1 of the recessed portion 11c, so that the heat dissipation area 15 is arranged at the position closest to the inside of the housing 11 in the recessed portion 11c, to reduce the probability of rainwater entering the housing 11 through the heat dissipation area 15. Rainwater needs to bypass the upper side wall 11c2 of the recessed portion 11c before it is possible to enter the housing 11 through the heat dissipation area 15. That is, rainwater needs to tilt at a relatively large angle before it is possible to bypass the upper side wall 11c2. This also makes it possible that in the case of general rainfall, the upper side wall 11c2 completely blocks the rainwater, thereby preventing the rainwater from entering the housing 11 through the heat dissipation area 15.

[0085] According to an embodiment of the present invention, the heat dissipation area 15 is arranged on the first side wall and / or the second side wall of the housing 11. Arranging the heat dissipation area 15 on the first side wall and / or the second side wall of the housing 11 can reduce the probability of rainwater entering the housing 11 through the heat dissipation area 15. Rainwater needs to bypass the upper side wall 11c2 of the recessed portion 11c before it is possible to enter the housing 11 through the heat dissipation area 15. Rainwater also needs to tilt at a relatively large angle before it is possible to bypass the upper side wall 11c2. This also makes it possible that in the case of general rainfall, the upper side wall 11c2 completely blocks the rainwater, thereby preventing the rainwater from entering the housing 11 through the heat dissipation area 15.

[0086] In an embodiment of the present invention, the heat dissipation area 15 can be arranged on the bottom wall 11c1, the first side wall and the second side wall. Arranging the heat dissipation area 15 in the above areas helps to increase the heat dissipation area of the charging base 1, thereby improving the heat dissipation effect of the charging base 1. Arranging the heat dissipation area 15 on the bottom wall 11c1, the first side wall and the second side wall can also reduce the probability of rainwater entering the inside of the charging base 1, and the reliability of the charging base 1 is good.

[0087] According to an embodiment of the present invention, the housing 11 includes a bottom for supporting the charging stand to stand, and a top opposite to the bottom. The side wall includes an upper side wall 11c2 disposed near the top. The angle between the connection between the outermost end of the upper side wall 11c2 and the lowermost end of the heat dissipation area 15 and the vertical direction is α and satisfies: 0° < α ≤ 60°. The angle between the connection between the outermost end of the upper side wall 11c2 and the lowermost end of the heat dissipation area 15 and the vertical direction can be adjusted by changing the depth of the recess 11c and / or the position of the heat dissipation area 15 in the vertical direction in the bottom wall 11c1. The above angle can be simulated as the inclination angle required for rainwater to bypass the upper side wall 11c2 in an extreme case. Setting the angle between the connection between the outermost end of the upper side wall 11c2 and the lowermost end of the heat dissipation area 15 and the vertical direction within the above range can avoid most of the rainwater, thereby ensuring the reliability of the charging stand 1. At the same time, setting the value range of α within the above range can minimize the encroachment of the recess 11c on the inner shell, and the spatial layout of the heat dissipation area 15 can also meet the heat dissipation requirements of the charging stand 1.

[0088] According to an embodiment of the present invention, the heat dissipation area 15 includes heat dissipation holes 151 provided on the outer surface of the housing 11. The heat dissipation holes 151 are respectively communicated with the accommodation space and the external space. The heat dissipation holes 151 can be configured as through holes penetrating the housing 11 in the thickness direction, which is convenient for the processing of the housing 11 and the layout of the heat dissipation area 15, so that the heat dissipation area 15 dissipates heat from the charging stand 1 through air circulation.

[0089] In an embodiment of the present invention, the outer end of the heat dissipation hole is higher than the inner end of the heat dissipation hole 151. The heat dissipation hole is inclined upward in the direction from the outside of the housing 11 to the inside of the housing 11 to further improve the rainproof effect of the heat dissipation area 15. Setting the heat dissipation hole to have a structure with a lower outer end and a higher inner end can further prevent rainwater from entering the charging stand 1 and improve the rainproof effect of the charging stand 1.

[0090] According to an embodiment of the present invention, the housing 11 includes a housing front part and a housing rear part disposed opposite to each other, and a housing side part located between the housing front part and the housing rear part. The housing front part is provided with a mating part 13 for connecting with the battery, and an air circulation channel is disposed in the housing side part.

[0091] The housing front part, the housing rear part, and the housing side part can enclose the accommodation space for accommodating electrical components. The housing front part can be adapted to be connected to the battery pack. By providing the mating part 13 on the housing front part, the connection between the charging stand 1 and the battery can be made stable, ensuring the stable connection between the battery pack and the charging stand 1.

[0092] The mating part 13 may include an electrically connected mating part 13a and a fixedly connected mating part 13b. Among them, the electrically connected mating part 13a is adapted to electrically connect the battery pack with the electrical components in the charging base 1, and the fixedly connected mating part 13b is adapted to contact and cooperate between the housing 11 and the battery pack to ensure the relative position stability between the charging base 1 and the battery pack during the charging process. During the charging process, the electrically connected mating part 13a electrically connects the battery pack with the electrical components inside the charging base 1, and the fixedly connected part ensures the relative position stability between the battery pack and the charging base 1, so that the battery pack can stably charge the electrical device through the charging base 1.

[0093] In an embodiment of the present invention, the mating part 13 includes a slide rail and a pole seat body 131. The slide rail is arranged at the front of the housing and is adapted to be inserted and mated with the battery pack. A plurality of electrode plates 132 adapted to be electrically connected to the battery pack are arranged on the pole seat body 131. An insertion piece adapted to cooperate with the slide rail can be arranged on the battery pack. During the cooperation process between the battery pack and the charging base 1, the insertion piece can be inserted into the slide rail along the extension direction of the slide rail, so as to keep a stable connection between the battery pack and the charging base 1. After the insertion piece and the slide rail are in place, the electrode plates 132 on the pole seat body 131 cooperate with the electrical connection ends on the battery pack to electrically connect the battery pack with the electrical components in the charging base 1.

[0094] According to an embodiment of the present invention, the slide rail includes a first slide rail 13b1 and a second slide rail 13b2 arranged at intervals from each other. The heat dissipation area 15 is arranged between the first slide rail 13b1 and the second slide rail 13b2. The arrangement of the first slide rail 13b1 and the second slide rail 13b2 can ensure more stable cooperation between the battery pack and the charging base 1. The first slide rail 13b1 and the second slide rail 13b2 can be arranged in parallel. The battery pack and the charging base 1 can be inserted and mated along the extension direction of the first slide rail 13b1 and the second slide rail 13b2, and at the same time, it can be avoided that the battery pack and the charging base 1 are offset during the insertion and mating process.

[0095] The heat dissipation area 15 is arranged between the first slide rail 13b1 and the second slide rail 13b2, so that the recessed part 11c on the housing 11 has sufficient layout space. There is a recessed part 11c between the first slide rail 13b1 and the second slide rail 13b2 of the housing 11, which can also avoid the recessed part 11c weakening the structural strength of the first slide rail and the second slide rail. In addition, the first slide rail and the second slide rail are configured to protrude from the outer surface of the housing 11, which can reduce the rainwater entering the recessed part 11c from the side to a certain extent, so as to improve the rainproof effect of the charging base 1.

[0096] In one embodiment of the present invention, after the battery pack is fitted with the charging base 1, the battery pack and the recess 11c face each other, and air can flow through the gap between the battery pack and the recess 11c, so that the air flow in the heat dissipation area 15 can dissipate heat from both the battery pack and the charging base 1 at the same time, increasing the heat dissipation area of the charging base 1 and making the overall heat dissipation effect better after the battery pack and the charging base 1 are fitted together.

[0097] According to one embodiment of the present invention, the front part of the housing is provided with an upper wall surface 103 of the front part of the housing connected to the upper side wall 11c2 of the recess 11c and a lower wall surface 104 of the front part of the housing connected to the lower side wall of the recess 11c. The extending directions of the upper wall surface 103 of the front part of the housing, the lower wall surface 104 of the front part of the housing, and the bottom wall 11c1 of the recess 11c are the same and are inclined at an angle to the vertical direction.

[0098] Arranging the housing 11 in the above manner can make the housing 11 have a lower center of gravity after being fitted with the battery pack, thereby improving the stability after the battery pack and the charging base 1 are fitted together. In addition, the inclined setting can give the charging base 1 a good appearance and improve the user experience.

[0099] Furthermore, as Figure 8 and Figure 10 shown, by making the extending directions of the upper wall surface 103 of the front part of the housing, the lower wall surface 104 of the front part of the housing, and the bottom wall 11c1 of the recess 11c the same and inclined at an angle to the vertical direction, the fitting between the battery pack and the charging base 1 can be made more convenient. The battery pack can be inserted obliquely into the charging base 1, improving the user experience.

[0100] According to one embodiment of the present invention, the charging base 1 further includes a cooling fan 16 disposed in the accommodation space. The cooling fan 16 faces the heat dissipation area 15, which can increase the flow rate of the gas, so that the gas can quickly pass through the heat dissipation area 15 to fully dissipate heat from the electrical components in the accommodation space of the charging base 1.

[0101] According to one embodiment of the present invention, the housing 11 is standing and includes a bottom for supporting the charging base 1 and a top opposite to the bottom. An accommodation space for accommodating electrical components is provided inside the housing 11, and a heat dissipation area 15 adapted to dissipate heat from the electrical components is formed on the outer surface of the housing 11. A recess 11c is provided on the housing 11, and the heat dissipation area 15 is disposed in the recess 11c; the housing 11 further includes a front part and a rear part of the housing disposed opposite to each other. A mating part 13 adapted to mate with the battery pack is provided on the front part of the housing. The mating part 13 includes: a slide rail and a pole seat body 131. The slide rail is disposed on the front part of the housing and is adapted to be plugged and mated with the battery pack. A plurality of electrode plates 132 adapted to be electrically connected to the battery pack are provided on the pole seat body 131.

[0102] The housing 11 according to the present invention is set up in a standing manner, so that the space occupied by the housing 11 in the horizontal direction is smaller, making full use of the space of the housing 11 in the vertical direction and improving the space utilization rate of the charging base 1. Moreover, the charging base 1 can simultaneously meet the heat dissipation requirements of the electrical components in the charging base 1 and has good rainproof ability.

[0103] In an embodiment of the present invention, the heat dissipation area 15 is arranged on the bottom wall 11c1 of the recess 11c to further improve the rainproof effect of the charging base 1 and ensure the area of the heat dissipation area 15.

[0104] According to an embodiment of the present invention, the side wall includes an upper side wall 11c2 near the top, and the heat dissipation area 15 is arranged on the upper side wall 11c2. Arranging the heat dissipation area 15 on the upper side wall 11c2 can effectively prevent rainwater from entering the charging base 1, and the rainproof effect is good.
