DETAILED DESCRIPTION

[0032] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application is clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work also fall within the scope of protection of the present application.

[0033] In the prior art, the appearance structure of the control box used to install the controller for controlling the rotation of the photovoltaic tracking bracket is as follows: Figure 1 As shown, its cross-section is as follows Figure 2 When designing and manufacturing this control box, the sealing ring is installed in the groove of the upper cover. Due to the limitation of the groove depth of the upper cover, a sealing ring that is too thick cannot be used. When the sealing ring is placed in the groove of the square upper cover, if the installer does not operate properly, the sealing ring may not be installed properly, resulting in a decrease in the sealing effect.

[0034] The present application embodiment provides a control box housing, such as Figures 3 to 7As shown, it includes a shell 100 and a cover body 200 detachably connected to the shell 100, the cover body 200 is snap-fitted and connected to one side of the shell 100, and the shell 100 is provided with a sealing groove 101 on the side connected to the cover body 200 for the edge of the cover body 200 to be inserted and embedded, and a sealing member 300 is provided at the bottom of the sealing groove 101. A boss 201 is circumferentially provided on the edge of the cover body 200 that is inserted and embedded in the sealing groove 101. When the cover body 200 is snap-fitted and connected to the shell 100, the boss 201 abuts against the sealing member 300 and can cause the sealing member 300 to deform to achieve sealing between the shell 100 and the cover body 200.

[0035] In the control box housing provided by the embodiment of the present application, the housing 100 is provided with a sealing groove 101 for the edge of the cover 200 to be inserted and embedded on one side of the housing 100 connected to the cover 200, and a sealing member 300 is provided at the bottom of the sealing groove 101. The sealing groove 101 is provided on the housing 100 instead of the cover 200, so that the depth of the sealing groove 101 can be increased without being restricted by the cover 200. A boss 201 is provided circumferentially on the edge of the cover 200 at the part inserted and embedded in the sealing groove 101. When the cover 200 is buckled and connected to the housing 100, the boss 201 abuts against the sealing member 300 and can cause the sealing member 300 to deform to achieve sealing between the housing 100 and the cover 200. The control box housing provided in the embodiment of the present application changes the traditional control box method of setting a groove on the upper cover to install a sealing ring. By setting a sealing groove 101 on the shell 100 and installing a seal 300, the installation of the seal 300 is no longer limited by the groove depth of the upper cover and cannot use a sealing ring that is too thick.

[0036] In the embodiment of the present application, the edge of the cover 200 is provided with a boss 201 in a circumferential direction at the portion where the cover 200 is inserted and embedded in the sealing groove 101. When the edge of the cover 200 is inserted and embedded in the sealing groove 101, the extra boss 201 can abut the sealing member 300. In this way, when the cover 200 is buckled and connected to the housing 100, the boss 201 can not only press the sealing member 300 into the bottom of the sealing groove 101 to avoid the situation where the worker does not install the sealing member 300 properly, but also squeeze the sealing member 300 to deform it, so that the one-line seal of the conventional upper cover sealing ring is transformed into two-line seals in the sealing groove of the housing 100. Figure 4 This is a comparison diagram of the metal control box in the prior art and the control box housing of the present application when sealed. Figure 4 It can be seen that Figure 4 In the middle, a shows an original seal, and b shows two seals of the present application. Through the above structure, the present application can improve the sealing effect between the shell 100 and the cover 200, reduce the probability of water leakage of the control box shell at the connection between the shell 100 and the cover 200, and isolate water vapor to prevent the generation of condensed water, thereby protecting the internal controller and reducing the workload and operation and maintenance costs of after-sales repair and replacement.

[0037] As an optional solution of the embodiment of the present application, the sealing member 300 is an elastic sealing ring or an elastic sealing layer after the adhesive is cured.

[0038] In practical applications, the sealing member 300 can be an elastic sealing ring or an elastic sealing layer after curing of adhesive, so that the boss 201 and the sealing member 300 work together. Figure 4 As shown in b, two seals can be formed on the periphery of the boss 201, thereby improving the sealing effect.

[0039] When the seal 300 uses an elastic sealing ring, the elastic sealing ring used can be installed in advance into the sealing groove 101 of the housing 100, and the sealing ring should be completely pressed into the bottom of the sealing groove 101. When it is used, glue can also be applied to the bottom of the sealing groove 101 to fix the sealing ring. As the use time increases, the sealing ring may no longer stick to the bottom of the sealing groove 101. Even if this happens, the present application can still press the sealing ring firmly to the bottom of the groove by squeezing the sealing ring through the boss 201. After opening the control box housing for inspection and maintenance, when the cover 200 is installed again, the boss 201 can press the sealing ring that is not in place to fit the bottom of the groove back into the bottom of the groove, so that the sealing ring is pressed into place to ensure the sealing effect.

[0040] When the seal 300 uses an elastic sealing layer after the adhesive is cured, a proper amount of adhesive can be applied to the sealing groove 101, and then the cover body 200 is buckled. After the adhesive is cured and expanded, an elastic sealing layer is formed as the seal 300 to achieve a good seal between the cover body 200 and the shell 100.

[0041] In some embodiments of the present application, the end of the boss 201 that abuts against the sealing member 300 is a protrusion with a square, arc-shaped or trapezoidal cross-section.

[0042] Since the edge of the cover 200 is provided with a boss 201 in the circumferential direction at the portion inserted and embedded in the sealing groove 101, in the absence of the sealing member 300, two separation spaces are formed between the boss 201 and the side wall of the sealing groove 101 in the sealing groove 101. When the sealing member 300 is installed, as shown in FIG. Figure 4 As shown in b, the seal 300 is squeezed and deformed by the boss 201. Since it is restricted by the side wall of the sealing groove 101, the seal 300 fills the two spaces formed between the boss 201 and the side wall of the sealing groove 101, so that the seal 300 is in a U shape in the sealing groove 101, forming two seals. The boss 201 is a protrusion with a square, arc or trapezoidal cross section at one end that abuts against the seal 300. In this way, when the boss 201 is squeezed and contacted with the seal 300, it can better act on the seal 300, so that the seal 300 can better fit the sealing groove 101 and the boss 201 after deformation.

[0043] In some embodiments of the present application, when the cover 200 is snap-fitted to the shell 100 , the cover 200 and the shell 100 are snap-fitted together at the same time, thereby ensuring that the cover 200 can be stably connected to the shell 100 when snap-fitted to the shell 100 .

[0044] In the embodiment of the present application, the cover 200 and the housing 100 are connected together by snapping, which is no longer the way in which the upper cover and the lower housing are connected by bolts in the traditional control box. Figure 1 As shown in the figure, the upper cover of the traditional control box is rectangular, and four bolts are used to install the upper cover. Due to manual operation, the torque of the four bolts is easily unbalanced. Therefore, under the condition of uneven force, the upper cover is easily deformed, and the size of the joints between the upper and lower shells is inconsistent, which makes the pressing force on the sealing ring uneven, resulting in poor sealing effect. In addition, the manufacturing error of parts, the installation torque error, and the thermal expansion and contraction caused by the change of ambient temperature further affect the sealing effect, thus causing water leakage.

[0045] The embodiment of the present application adopts a snap-fit ​​connection method to connect the cover 200 and the housing 100 together. Since bolts are no longer used and the position of the snap-fit ​​connection is fixed, it is possible to avoid the situation where the tightness is difficult to maintain consistency when manually tightening the bolts, thereby preventing the cover 200 from being deformed due to the screwing of the bolts. The present application adopts a snap-fit ​​connection method, so that the uniformity of the compression force on the seal 300 when it is under pressure is also improved, thereby improving the sealing effect and reducing the risk of water leakage.

[0046] Optionally, the cover body 200 and the shell 100 are snap-connected by an internal snap-fit ​​connection or an external snap-fit ​​connection. In the present embodiment, the cover body 200 and the shell 100 can be easily connected regardless of whether they are snap-fitted by an internal snap-fit ​​connection or an external snap-fit ​​connection. After the cover body 200 and the shell 100 are snap-connected, the edge of the cover body 200 is always inserted and embedded in the sealing groove 101, so that the boss 201 can squeeze the seal 300 more evenly.

[0047] In some embodiments of the present application, the cover 200 and the housing 100 are provided with a snap assembly for snap connection. By providing the snap assembly, the snap connection between the cover 200 and the housing 100 can be achieved. In this embodiment, the snap assembly includes a snap 202 and a snap groove 105, such as Figure 5-Figure 8As shown, when the cover 200 and the housing 100 are snap-fitted and connected in an embedded snap-fitting manner, a snap-fitting snap 202 is provided on the inner side of the cover 200, and a snap-fitting groove 105 is provided on the housing 100 corresponding to the snap-fitting snap 202. When the cover 200 is snapped on the housing 100, the snap-fitting assembly can also facilitate the workers to install and position the cover 200, thereby ensuring that the workers can install the cover 200 in a relatively standard and fast manner. Of course, in addition to the above-mentioned snap-fitting connection by providing the snap-fitting snap 202 on the cover 200 and the snap-fitting groove 105 on the housing 100, the snap-fitting connection can also be achieved by providing the snap-fitting groove on the cover 200 and the snap-fitting snap on the housing 100, or the cover 200 has both the snap-fitting snap and the snap-fitting groove, and the housing 100 also has the snap-fitting snap and the snap-fitting snap correspondingly to achieve the snap-fitting connection. In addition, in addition to using a snap assembly having a snap 202 and a snap groove 105, the snap assembly can also use a snap plate or a snap rod with a snap connection function to achieve a snap connection, as long as the snap plate or the snap rod is offset and arranged on the cover body 200 and the shell 100 accordingly. This application will not elaborate on this.

[0048] In the prior art, the backup power supply configured to achieve black start is usually built into the control box. Due to cost or process reasons, the failure rate of the backup power supply is also relatively high. However, to repair or replace the backup power supply, the control box needs to be opened. In order to open the control box, it is usually necessary to remove it from the bracket, and then reinstall it after repair and replacement. This series of operations will lead to low maintenance efficiency and high maintenance costs.

[0049] In some embodiments of the present application, the cover body 200 is connected to the rear side of the shell 100, which is different from the position of the upper cover of a traditional control box. The upper cover of a traditional control box is located above the lower shell, while the control box shell of the embodiment of the present application sets the cover body 200 on the rear side of the shell 100, so that the outer surface of the cover body 200 is facing backwards instead of upwards. This method is convenient for workers to open the cover body 200 for inspection and maintenance, and can alleviate the impact of rain on the cover body 200.

[0050] Among them, Figure 7 As shown, the housing 100 is provided with a first accommodating cavity 102 inside a side connected to the cover body 200. Figure 6 As shown, a second accommodating cavity 103 which is recessed toward one side of the cover body 200 is provided on the front side of the shell 100, thereby forming two accommodating cavities in front and behind the shell 100. The first accommodating cavity 102 on the rear side serves as the main accommodating cavity for installing electronic components, and the second accommodating cavity 103 on the front side serves as a secondary accommodating cavity, wherein the second accommodating cavity 103 can be used to insert the backup battery 400 for placing the control box. This changes the structural design of a accommodating cavity in the traditional way, makes the space for placing the backup battery 400 independent, and facilitates the maintenance and replacement of the backup battery 400.

[0051] See also Figure 3 and Figure 8 The outer side of the second accommodating cavity 103 is detachably connected with a backup battery cover 500 for sealing the opening of the second accommodating cavity 103. A sealing gasket 800 is provided at the connection between the backup battery cover 500 and the housing 100. When the backup battery 400 fails, the entire control box housing can be opened without removing it from the bracket. The backup battery cover 500 can be conveniently and quickly repaired and replaced. When the control box housing of the present application is installed on the bracket, the upper area of ​​the housing 100 can be used to fix it with the bracket by bolts.

[0052] In some embodiments of the present application, the second accommodating cavity 103 is opened on the upper front side of the housing 100. The opening of the second accommodating cavity 103 also enables additional support inside the housing 100 to improve the strength of the entire control box housing. Figure 3 and Figure 6 As shown, a concave wiring area 104 is provided at the lower front side of the housing 100, which reduces the risk of water leakage of the control box housing. A mounting hole 1041 is provided on the shell surface of the wiring area 104. In actual applications, the communication interface, photovoltaic PV interface, grounding port, etc. can be installed through the mounting holes 1041 in the wiring area 104 to meet the use requirements of the control box used in the photovoltaic power generation field, or the battery pack lead wire can be connected to the control board in the box through the mounting holes 1041. It can be understood that in actual applications, the specific number and form of the mounting holes 1041 at the wiring area 104 can be flexibly designed according to the use requirements.

[0053] In some embodiments of the present application, Figure 3 As shown, the backup battery cover 500 is provided with two symmetrical handles 501, and the handles 501 are concave handles or convex handles. Fig. 9 and Fig.10 The backup battery cover 500 with a concave handle and a convex handle are shown respectively. The backup battery cover 500 adopts a concave handle so that the handle 501 does not protrude from the front side of the shell 100, reducing the impact of bumps on internal components and reducing the risk of damage. The backup battery cover 500 adopts a convex handle to facilitate the pulling and pulling of the backup battery cover 500. In this embodiment, the backup battery cover 500 has a protrusion on the side facing the second accommodating cavity 103, and connection holes are respectively provided at the four corners of the plate surface of the backup battery cover 500. The backup battery cover 500 is fixed to the front side of the shell 100 by screws in the connection holes, thereby closing the second accommodating cavity 103.

[0054] Optionally, a spare inner groove 106 is also provided below the left / right side surface of the shell 100. In the present embodiment, an inner groove 106 is also provided below the left side surface or the right side surface of the shell 100. Compared with the smooth surface design, the space utilization rate is increased, the shell strength is enhanced, and the molding difficulty can be reduced while the shell is strengthened. When the control box shell of the embodiment of the present application is used as the shell of the control box used to control the rotation of the photovoltaic tracking bracket in the photovoltaic power generation field, the emergency stop switch 700 can be installed by opening a hole at this inner groove 106 to facilitate operation in an emergency state. Similarly, the inner groove 106 adopts a concave structural design, and after the exposed device is installed, the risk of water leakage in the control shell is reduced. The inner groove 106 and the wiring area 104 adopt a concave protective structure design, and a sealing gasket is added when the emergency stop switch 700 and each control box interface are installed, so as to improve the protection level and reduce the risk of water leakage.

[0055] Optionally, the shell 100 and the cover 200 are both made of engineering plastics. In this embodiment, the material of the shell 100 and the cover 200 is replaced from traditional metal material to engineering plastics, which not only reduces production costs, but also has light weight and low surface hardness compared to metal. After use, it can reduce the weight of the control shell or control box, facilitate installation and transportation, and avoid the problem of poor contact sealing between hard objects.

[0056] The present application also provides a control box, such as Figure 8 As shown, it includes the control box housing provided by the above-mentioned embodiment of the present application and the controller 600 installed in the control box housing. Such a control box installs the controller 600 in the control box housing given in the present application, and the connection between the cover body 200 and the shell 100 has good sealing performance, which reduces the risk of water leakage.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
