[0029] refer to Figures 1 to 5 , an embodiment of the present application provides a plastic part with a reinforced structure, which may include a panel 1 and a bottom shell 2 that are arranged relative to each other and sealed together, and the bottom shell 2 has a accommodating cavity for placing a support member 3; the panel 1 may include a supporting rib 12, which is arranged on the side of the panel 1 facing the support member 3 and has a gap between the rib and the support member 3.

[0030] The embodiment of the present application proposes a plastic part with a reinforced structure, in which the panel 1, the bottom shell 2 and the support ribs 12 are all made of plastic material. The panel 1 is the A-side of the plastic part, and the support ribs 12 are arranged on the panel 1. When the panel 1 is deformed by a collision, the support ribs 12 resist the support member 3 to prevent the panel 1 from further deformation. It not only effectively supports the panel 1, but also greatly increases the strength and anti-collision performance of the panel 1, ensuring that when the panel 1 is subjected to an external collision impact, the deformation of the area is reduced to a minimum; in this way, a plastic shell is used to replace the traditional sheet metal shell, which not only has the advantages of being beautiful, low-cost and highly manufacturable, but also has a good anti-collision effect.

[0031] It should be understood that the A-side of the plastic part refers to the side that is often seen or used by the user, that is, the side that is easily damaged by collision.

[0032] Among them, Figure 1 As shown, the bottom shell 2 has a bottom wall and four side walls, and the support member 3 is fixed to the bottom wall with bolts; in addition, when connecting the panel 1, the panel 1 can be first covered on the bottom shell 2, and then the bottom shell 2 and the panel 1 can be connected using self-tapping screws from the side of the bottom shell 2 away from the panel 1.

[0033] refer to Figure 2 In an exemplary embodiment, the plastic part with a reinforced structure may further include a plurality of support columns 11, and the plurality of support columns 11 are all arranged on the side of the panel 1 facing the support member 3; wherein, the area where the support columns 11 are located and the area where the support ribs 12 are located are arranged in a second direction, and the second direction is the same as the length direction of the panel 1; in the first direction, the height of the support columns 11 is the same as the height of the support ribs 12, and the first direction is perpendicular to the panel 1.

[0034] Specifically, such as Figure 2 As shown, the second direction is the Y direction, which is the length direction of the panel 1; the support ribs 12 and the support columns 11 are arranged in the second direction, as shown in FIG. Figure 2 As shown, in the second direction, the panel 1 can be divided into two parts, the upper and lower parts, the support ribs 12 are at the upper part of the panel 1, and the support columns 11 are located at the lower part of the panel 1. In this way, when the upper or lower part of the panel 1 is hit, it can be effectively supported by the support ribs 12 or the support columns 11, further improving the anti-collision effect of the panel 1.

[0035] It should be understood that the height of the support column 11 is the same as the height of the support rib 12. In this way, when the support rib 12 and the support column 11 both conflict with the support member 3, the deformation amount between the upper and lower parts of the panel 1 is close, preventing the deformation amount difference between the upper and lower parts of the panel 1 from being too large, causing damage to the panel 1.

[0036] At the same time, the support columns 11 are not continuous, so it is more convenient to assemble components that need to be anti-collision in the area where the support columns 11 are located.

[0037] refer to Figure 2 and Figure 4 In an exemplary embodiment, the plurality of support columns 11 include first support columns and second support columns, part of the first support columns and part of the second support columns constitute one support column group, another part of the first support columns and another part of the second support columns constitute another support column group, and the two support column groups are arranged opposite to each other in the second direction, and there are at least two first support columns and at least two second support columns in each support column group;

[0038] The orthographic projections of the first support column and the second support column in a support column group on the panel 1 are respectively the first projection and the second projection, the orthographic projection of the support member 3 on the panel 1 is the support projection, and the support projection has a first edge and a second edge opposite to each other in a third direction, and the third direction is the same as the width direction of the panel 1;

[0039] Within the same support column group, the second projection intersects the first edge and the second edge respectively, the first projection is located between the first edge and the second edge, and in the second direction, the second projection is located on the side of the first projection close to the positive projection of another support column group on the panel 1.

[0040] Specifically, such as Figure 2 and Figure 4 As shown, the third direction is the Z direction, that is, the width direction of the panel 1; there are ten support columns 11 on the panel, wherein each support column group includes five support columns 11; wherein, the five support columns 11 in each support column group are divided into three first support columns and two second support columns.

[0041] Further, such as Figure 2 As shown, within the same support column group, the second projection intersects with the first edge and the second edge respectively, the first projection is located between the first edge and the second edge, and in the second direction, the second projection is located on the side of the first projection close to the positive projection of another support column group on the panel 1. In this way, the ten support columns 11 are distributed as evenly as possible. When a collision occurs in the area where the support columns 11 are located on the panel 1, the support columns 11 can support the panel 1 as evenly as possible, and the supporting effect on the panel 1 is better.

[0042] Among them, in the same support column group, when there are two second projections, the two second projections intersect with the first edge and the second edge respectively. When the number of second projections is greater than two, compared with the two second projections, the extra second projections can intersect with the first edge or the second edge, but the number of second projections intersecting with the first edge should be kept as close as possible to the number of second projections intersecting with the second edge.

[0043] At the same time, the component that needs to be protected from collision can be arranged between two support column groups. In this case, each support column 11 is arranged around the periphery of the component that needs to be protected from collision, and the protection effect is better.

[0044] In addition, within the same support column group, the second projection intersects the first edge and the second edge respectively, so that the two second support columns are respectively close to the two sides of the support member 3 in the third direction, that is, the second support columns correspond to the two side edges of the support member 3 in the third direction. When the area corresponding to the second support column on the panel 1 collides, the second support column collides with the support member 3, and at this time the second support column is close to the side edge of the support member 3, so as to ensure the reliability of the support column group in supporting the panel 1.

[0045] It should be understood that the greater the number of first support columns and second support columns, the better the supporting effect, but too many support columns 11 will affect the installation of interactive components and the overall assemblability of the panel 1 will also deteriorate. The above-mentioned solution of using ten support columns 11 is the preferred solution.

[0046] refer to Figure 2 In an exemplary embodiment, the plastic part with a reinforced structure may further include a connecting rib 13, which is arranged on the side of the panel 1 facing the support member 3 and connects adjacent first support columns in the same support column group; wherein, in the first direction, the height of the connecting rib 13 is the same as the height of the support column 11.

[0047] Specifically, such as Figure 2 As shown, adjacent first support columns in the same support column group are connected by connecting ribs 13, and in the first direction, the height of the connecting ribs 13 is the same as the height of the support column 11. This not only increases the strength of the first support column, but also when the area where the first support column is located is hit by a collision, the first support column and the connecting ribs 13 will jointly resist the support member 3, greatly increasing the contact area, making the support effect of the support member 3 on the panel 1 more effective and reliable, and the anti-collision effect of the panel 1 better.

[0048] refer to Figure 2 In an exemplary embodiment, the plastic part with a reinforced structure may further include a plurality of reinforcing ribs 14 , which are all arranged on the side of the panel 1 facing the support member 3 and connected to the support column 11 and the support rib 12 .

[0049] Specifically, such as Figure 2 As shown, a plurality of reinforcing ribs 14 are arranged on the panel 1 in a horizontal and vertical manner. The reinforcing ribs 14 are connected to the support columns 11 and the support ribs 12 , further improving the stability of the support ribs 12 and the support columns 11 , while improving the strength of the panel 1 .

[0050] It should be noted that if Figure 2As shown, the outer periphery of the panel 1 has a flange structure facing the bottom shell 2, a groove can be set on the flange structure, and the side wall of the bottom shell 2 can be inserted into the groove of the flange structure, thereby improving the sealing effect after the panel 1 and the bottom shell 2 are connected; wherein, the reinforcing rib 14 is also connected to the flange structure on the panel 1, further improving the strength of the panel 1.

[0051] In an exemplary embodiment, in the first direction, the ratio of the distance between the supporting rib 12 and the supporting member 3 to the height of the supported rib 12 is a, and 0.08<a<0.18. The first direction is perpendicular to the panel 1 .

[0052] Specifically, a can be 0.09, 0.11, 0.13, 0.15, 0.17, etc. In a preferred embodiment, the value of a can be 15 / 113. At this time, when the panel 1 is installed, a gap is reserved between the support column 11 and the support member 3, which not only ensures a certain deformation of the plastic part, but also eliminates manufacturing tolerances and improves the public welfare of assembly.

[0053] In an exemplary embodiment, in the first direction, a ratio of the height of the reinforcing rib 14 to the height of the supporting column 11 is b, and 0.4<b<0.6.

[0054] Specifically, b can be 0.45, 0.5, 0.55, etc. In a preferred embodiment, the value of b can be 60 / 113, so that the reinforcing rib 14 itself has a stronger structure. At the same time, after the reinforcing rib 14 is connected to the support column 11 and the support rib 12, the strength of the support column 11 and the support rib 12 is effectively improved.

[0055] In a preferred embodiment, the panel 1 can be rectangular, with a length of 400 mm and a width of 300 mm. When the thickness of the panel 1 is the conventional thickness of 3.5 mm, even if the panel 1 is arranged with horizontal and vertical crisscross reinforcing ribs in a traditional manner, the strength of the panel 1 still cannot reach the anti-collision level IK08 or above; therefore, the above-mentioned structures are added so that the anti-collision level of the panel 1 can also fully meet the requirements of IK08 and IK10, with high strength and good anti-collision effect.

[0056] Among them, in the first direction, the height of the flange structure of the panel 1 is 20 mm, the height of the support column 11, the height of the support rib 12 and the height of the connecting rib 13 are all 11.3 mm, and the height of the reinforcing rib 14 is 6 mm.

[0057] refer to Figure 1 On the basis of the above embodiment, the embodiment of the present application further provides a charging device, which may include the above-mentioned plastic part with a reinforced structure; wherein the support member 3 is a charging module of the charging device.

[0058] Specifically, the charging device can be a charger or a charging pile, etc., and the bottom shell 2 and the panel 1 together constitute the outer shell of the charging device. The panel 1 is used as the A side of the charging device, and the relevant components for interacting with the user can be set on the panel 1, specifically, they can be set between the two support column groups on the panel 1 to provide anti-collision protection for the relevant components for interacting with the user.

[0059] In an exemplary embodiment, the charging device may further include an interactive element, which is arranged on the side of the panel 1 facing the support 3; wherein, in the first direction, the height of the interactive element is less than the height of the support rib 12, and the interactive element may include a light board 5 and / or a card swiping board 6, and the first direction is perpendicular to the panel 1.

[0060] Specifically, in the first direction, the height of the light board 5 and the card swiping board 6 is less than the height of the support column 11. When the panel 1 is collided, the support column 11 contacts the outer shell of the support member 3, that is, the metal shell of the charging module. The light board 5 and the card swiping board 6 do not contact the support member 3. At the same time, the deformation of the panel 1 is small, so the support column 11 can effectively protect the light board 5 and the card swiping board 6 from being damaged or falling off.

[0061] refer to Figures 1 to 3 In an exemplary embodiment, the bottom shell 2 has a first side wall and a second side wall adjacent to each other, an air inlet 21 is provided on the first side wall, and an air outlet 22 is provided on the second side wall; a fan is provided on the side of the support member 3 facing the air inlet 21, and an exhaust port is provided on the side of the support member 3 away from the air inlet 21; the charging device may further include a spoiler 4, one end of the spoiler 4 is connected to the second side wall and the connection area is located at the end of the air outlet 22 close to the first side wall, the other end of the spoiler abuts against the support member 3 and is located at the end of the air outlet 22 away from the second side wall; the support rib 12 may include a contact section 121 and a connecting section 123, the contact section 121 correspondingly contacts the spoiler 4; the connecting section 123 is connected to the contact section 121, and the connecting section 123 is located between the support member 3 and the panel 1; wherein, in the first direction, the height of the support rib 12 is the height of the connecting section 123, and the first direction is perpendicular to the panel 1.

[0062] Specifically, when the charging device is in use, the air inlet 21 faces the ground, and the second direction is the same as the direction of gravity. When the fan is working, air is drawn from the air inlet 21 through the interior of the support 3 and blown out from the exhaust side of the support 3 to dissipate heat for the support 3. After being discharged from the exhaust port, the airflow further flows to the spoiler 4, is guided by the spoiler 4, and is finally discharged from the air outlet 22.

[0063] Furthermore, when external impurities enter the bottom shell 2 from the air outlet 22 , they will be blocked by the spoiler 4 , and due to the influence of their own gravity, the impurities will gradually move along the spoiler 4 and eventually be discharged from the air outlet 22 .

[0064] It should be understood that external impurities may include debris, rainwater, etc. Impurities or mosquitoes first find it difficult to resist the wind flow at the air outlet 22 from entering the air outlet 22. Even in weather such as strong winds or heavy rain, impurities entering the air outlet 22 will slide out of the air outlet 22 along the spoiler 4. At the same time, the wind flow blown out from the air outlet 22 will further push the impurities on the spoiler 4 to slide out of the air outlet 22, making the protection effect better; at the same time, the air inlet 21 is at the bottom, and impurities are also difficult to enter the bottom shell 2 from the air inlet 21 at the bottom. In this way, the heat dissipation form of lower air intake and upper air outlet can effectively reduce the entry of rainwater, dust and mosquitoes, protect internal electrical components, and extend the life of the entire machine.

[0065] It should be understood that when the fan is working, the air outlet 22 always blows out air, and it is more difficult for external impurities to enter the bottom shell 2 through the air outlet 22, so the protection effect is better.

[0066] Among them, the side of the spoiler 4 close to the bottom wall is connected to the bottom wall, and the side of the spoiler 4 close to the panel 1 is connected to the interference section 121, such as Figure 2 and Figure 4 As shown, the shape of the specific interference section 121 can be consistent with the shape of the spoiler 4, and a groove can be provided on the side of the interference section 121 facing the bottom wall, and the side of the spoiler 4 connected to the interference section 121 can be inserted into the groove, thereby improving the sealing effect and preventing the airflow discharged from the exhaust port from flowing back to the air inlet 21 through the gap between the interference section 121 and the spoiler 4.

[0067] Further, such as Figure 2 and Figure 3 As shown, there are two air outlets 22, which are opened on two opposite side walls; there are two spoilers 4, and the two spoilers 4 correspond to the two air outlets 22 one by one, wherein the support member 3 is located between the two spoilers 4, and there are two corresponding interference sections 121, which correspond to the two spoilers 4 one by one, so that the heat dissipation effect is better. Figure 3 The direction indicated by the arrow is the direction of wind flow.

[0068] In addition, the connecting section 123 can be connected to the end of the interfering section 121 away from the first side wall, such as Figure 2 As shown, when there are two interference sections 121, the connecting section 123 is located between the two interference sections 121; in the first direction, when the height of the connecting section 123 is 11.3 mm, even if a gap of 1.5 mm is maintained between the connecting section 123 and the support member 3, only a very small part of the airflow will flow back to the air inlet 21 through the gap between the connecting section 123 and the support member 3, which will hardly affect the heat dissipation effect of the support member 3.

[0069] The above are only preferred embodiments of the present application and do not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
