[0056] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application may also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present application.

[0057] In order to more clearly illustrate the embodiments of the present application or the technical solutions in the prior art, the specific implementation methods of the present application will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present application. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

[0058] In order to simplify the drawings, only the parts related to the present application are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically drawn or marked.

[0059] In this document, it should be noted that, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense, for example, it can be a fixed connection, or a detachable connection, or an integral connection; or it can be a mechanical connection, or it can be an electrical connection; or it can be a direct connection, or it can be indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0060] In the embodiments shown in the drawings, directional indications (such as up, down, left, right, front, and back, etc.) are not absolute but relative when describing the structure and movement of each component, and are not used to limit the direction of the product in actual use.

[0061] In addition, in the description of the present application, ordinal numbers, such as "first", "second", etc., are only used to distinguish and describe related objects, and cannot be understood as indicating or implying the relative importance or order between the related objects.

[0062] According to an example embodiment provided by this application, see Figures 1 to 4 A photovoltaic tracker control box includes a box body 100, a first cover body 200 and a second cover body 300. The box body 100 has a chamber 101, and the top and side walls of the box body 100 are respectively provided with a first opening 102 and a second opening 103 connected to the chamber 101; the first cover body 200 and the second cover body 300 are respectively covered on the first opening 102 and the second opening 103.

[0063] The box 100 is provided with a mounting frame at the bottom of the chamber 101, and the mounting frame divides the inner chamber of the box 100 into a first mounting chamber and a second mounting chamber, wherein the first mounting chamber is connected to the first opening 102, and the second mounting chamber is connected to the second opening 103. At this time, one of the first mounting chamber and the second mounting chamber can be used to install the battery pack 400, and the other can be used to install the circuit board 500.

[0064] This embodiment divides the inner chamber 101 of the box 100 into two parts, so that the battery pack 400 and the circuit board 500 can be stored in different installation cavities (first installation cavity, second installation cavity) respectively; at the same time, this embodiment sets a first opening 102 connected to the first installation cavity and a second opening 103 connected to the second installation cavity on the top and side walls of the box 100, respectively, to form a double-opening structure, and the user can directly take and put the battery pack 400 or disassemble and install the circuit board 500 through the corresponding openings, and the components in different installation cavities do not affect each other during the whole process. That is, if the user needs to take the battery pack 400, the battery pack 400 can be directly taken out and put back from the corresponding installation cavity, without involving the disassembly and installation of the circuit board 500; correspondingly, when the user needs to disassemble and install the circuit board 500 during the subsequent maintenance process, there is no need to remove the battery pack 400 in advance. Compared with the prior art, in which the circuit board 500 is arranged at the bottom of the box body 100, the user needs to first remove the battery pack 400 and other components above the circuit board 500 before disassembling and maintaining the circuit board 500. This embodiment adopts a double-opening structure to allow the circuit board 500 and the battery pack 400 to be installed separately, which is more conducive to the maintenance of the photovoltaic tracker control box, and is easy to operate and highly practical.

[0065] In order to further improve the convenience for users to disassemble and assemble the circuit board 500 and take the battery pack 400, the circuit board 500 is preferably installed in the first chamber, so that the user can disassemble and assemble the circuit board 500 from the first opening 102 on the top of the box 100. Compared with the situation where the user needs to disassemble and assemble the circuit board 500 from the second opening 103 on the side wall of the box 100 when the circuit board 500 is installed in the second installation cavity, this setting is more conducive to the user's daily maintenance. At this time, the battery pack 400 is installed in the second chamber, and the user can directly pull out or put back the battery pack 400 through the second opening 103 on the side wall of the box 100, forming a drawer-like structure, without the need to remove the circuit board 500 or other components, which is conducive to the user's replacement or inspection of the battery pack, and the structural setting is more reasonable and practical.

[0066] Specifically, see Figure 4 , Figure 5 and Figure 8 The mounting frame includes two spaced-apart side panels 120, and a space is formed between the two side panels 120 for the battery pack 400 to pass through, which is the second mounting cavity. At this time, the second opening 103 is opened on the side wall of the box body 100 on the side of the extending direction of the side panel 120, so that the battery pack 400 can enter and exit the mounting cavity. When the battery pack 400 is installed in the mounting cavity, the two side panels 120 can limit the lateral shaking of the battery pack 400.

[0067] Specifically, the mounting frame also includes a top plate 130 , which is fixed to the top of the two side plates 120 and can limit the battery pack 400 from shaking up and down.

[0068] Furthermore, the mounting frame further includes a limiting plate 110, which is disposed at one end of the two side plates 120 away from the second opening 103 and is disposed opposite to the second opening 103. When the second cover 300 is covered on the second opening 103, the second cover 300 can press the battery pack 400 against the limiting plate 110, thereby limiting the axial shaking of the battery pack 400.

[0069] In this embodiment, the top plate 130, the two side plates 120 and the limiting plate 110 are jointly arranged to form the above-mentioned second installation cavity, and the top plate 130, the two side plates 120, the limiting plate 110 and the second cover body 300 can jointly limit the displacement of the battery pack 400, thereby realizing stable fixation of the battery pack 400. There is no need to set a threaded locking position to lock the battery pack 400, which is convenient for users to take the battery pack 400, and the structure is simple and practical.

[0070] In a specific embodiment, the top plate 130 extends along its length direction to the side wall of the chamber 101 with the second opening 103, effectively strengthening the overall strength of the mounting frame. In addition, a plurality of reinforcing ribs 190 may be provided on the side away from each other of the two side plates 120 to further strengthen the overall strength of the mounting frame.

[0071] In a preferred embodiment, the depth of the second installation cavity is adjustable and can be adapted to battery packs 400 of different sizes. Specifically, the mounting frame also includes a baffle 140, and at least one latch is provided at one end of the mounting frame top plate 130 away from the second opening 103. Inserting the baffle 140 into the latch can reduce the depth of the second installation cavity. In particular, when the number of latches is at least two, the depth of the second installation cavity can be further changed by changing the latch into which the baffle 140 is inserted, so that the second installation cavity can be adapted to battery packs 400 of more specifications, and has strong versatility, which is conducive to placing the photovoltaic tracker control box provided by this embodiment in areas with different climatic conditions.

[0072] Specifically, there are two latching positions, which can realize three-level adjustment of the depth of the second installation cavity. When the baffle 140 is not inserted, the depth of the second installation cavity is the largest; when the baffle 140 is inserted into the latching slot 1321 closer to the limit plate 110, the depth of the second installation cavity becomes smaller than when the baffle 140 is not inserted; when the baffle 140 is inserted into the latching slot 1321 closer to the second opening 103, the depth of the second installation cavity is the smallest.

[0073] As a preference, see Figure 4 , Figure 5 and Figure 8The top plate 130 is provided with an avoidance hole 131, which penetrates to the end of the top plate 130 away from the second opening 103. The avoidance hole 131 can prevent the mounting frame from being damaged by the bulging of the battery pack 400, thereby improving the service life of the photovoltaic tracker control box to a certain extent. Relatively speaking, a groove 170 can also be provided at the bottom of the mounting cavity, which can also reduce the risk of damaging the mounting frame structure due to the bulging of the battery pack 400, and further improve the service life of the photovoltaic tracker control box.

[0074] At this time, the top plate 130 includes a retaining edge 132 formed at the top of the two side plates 120, and at least one slot 1321 is provided at one end of the two retaining edges 132 away from the second opening 103, and the slots 1321 on the two retaining edges 132 correspond to each other and are arranged opposite to each other. Among them, the two opposite slots 1321 together form a locking position, and the depth of the second installation cavity can be reduced by inserting the baffle 140 into the locking position, especially when the number of the locking positions is at least two, by inserting the baffle 140 into different locking positions, the depth of the second installation cavity can be further changed, so that the installation cavity can adapt to battery packs 400 of different sizes, and the versatility is strong, which is conducive to the use of the photovoltaic tracker control box provided by this embodiment in areas with different climatic conditions.

[0075] Specifically, two slots 1321 are provided on each retaining edge 132, and the two retaining edges 132 form two positions, which can realize three-level adjustment of the depth of the second installation cavity. When the baffle 140 is not inserted, the depth of the second installation cavity is the largest; when the baffle 140 is inserted into the position closer to the limit plate 110, the depth of the second installation cavity becomes smaller than when the baffle 140 is not inserted; when the baffle 140 is inserted into the position closer to the second opening 103, the depth of the second installation cavity is the smallest.

[0076] When the top plate 130 is not provided with the avoidance hole 131, the top plate 130 is a whole rectangular plate-shaped structure, that is, the top of the second installation cavity is closed, and the mounting frame as a whole is a box-shaped structure with an opening on the side wall. In this case, at least one waist-shaped hole can be directly opened on the top plate 130 for the limiting plate 110 to insert, and one waist-shaped hole forms a clamping position. Inserting the baffle 140 into the clamping position can reduce the depth dimension of the second installation cavity. In particular, when the number of clamping positions is at least two, by inserting the baffle 140 into different clamping positions, the depth of the second installation cavity can be further changed.

[0077] Specifically, two waist-shaped holes are provided on the top plate 130 , and the two waist-shaped holes are arranged in sequence along the extension direction of the side plate 120 , forming two clamping positions in total, so as to realize three-level adjustment of the depth of the second installation cavity.

[0078] In all the above embodiments including the baffle 140, see Figures 5 to 7A block 141 is provided on the top of the baffle 140. When the baffle 140 is inserted into the blocking position, the block 141 is suitable for abutting against the side of the retaining edge 132 (top plate 130) away from the first opening 102, so as to reduce the risk of the limiting plate 140 accidentally disengaging from the blocking position due to vibration or main shaft rotation (the photovoltaic tracker control box is fixed on the main shaft and rotates with the main shaft), thereby losing the risk of limiting the solar panel.

[0079] Among them, a first guide slope 1411 is provided on the side of the block 141 facing the bottom of the baffle 140, and a second guide slope 1322 is provided on the side of the slot 1321 facing the first opening 102. The first guide slope 1411 and the second guide slope 1322 cooperate with each other, which is more conducive to guiding the block 141 to pass through the slot 1321 and abut against the side of the retaining edge 132 (top plate 130) away from the first opening 102.

[0080] In actual production, the first guide slope 1411 and the second guide slope 1322 may be inclined surfaces or curved surfaces, which are not limited here and are within the protection scope of the present application.

[0081] Relatively speaking, a limiting surface 1412 is provided on one side of the block 141 facing the top of the baffle 140. The limiting surface 1412 may be a plane or a relatively gentle slope, an arc surface, etc. The user needs to exert a certain amount of force to pull out the block, which plays a better role in preventing the block from accidentally falling off.

[0082] Specifically, there are four clamping blocks 141, two of which are arranged on the side of the limiting plate 140 facing the second opening 103 and are respectively located in the area of ​​the limiting plate 140 close to the two side plates 120, and the other two clamping blocks 141 are arranged on the side of the limiting plate 140 away from the second opening 103 and are respectively located in the area of ​​the limiting plate 140 close to the two side plates 120, so that the clamping effect is better and more stable.

[0083] Further, see Figure 7 A third guide slope 142 is provided at the bottom of the limiting plate 140, which can guide the limiting plate 140 to be quickly inserted into the position, which is beneficial for the user to adjust the depth of the chamber 101, and the operation is convenient and quick.

[0084] Specifically, the box body 100 opens a limiting groove 160 at the bottom of the installation cavity. When the baffle 140 is inserted into the locking position, the bottom of the baffle 140 can be locked in the limiting groove 160, thereby limiting the displacement of the bottom of the baffle 140 and improving the structural stability of the mounting frame.

[0085] Preferably, a plurality of reinforcing ribs 190 are provided on the side of the baffle 140 away from the second opening 103 , which can effectively improve the structural strength of the baffle 140 , thereby improving the structural strength and stability of the mounting frame. The baffle 140 can also be plugged in and out by utilizing the reinforcing ribs 190 .

[0086] In all the above embodiments, see Figure 4 , Figure 5 and Figure 8 The box body 100 is provided with a plurality of supporting platforms 150 on the periphery of the mounting frame, and the heights of the plurality of supporting platforms 150 are all higher than the heights of the side panels 120. At this time, the plurality of supporting platforms 150 jointly support the circuit board 500 to form a mounting position for mounting the circuit board 500, so that the circuit board 500 is mounted on the side of the battery pack 400 close to the first opening 102.

[0087] In this embodiment, the circuit board 500 is fixed above the battery pack 400 through the mounting position. The user only needs to open the first cover 200 to directly act on the circuit board 500 to disassemble, assemble and repair it. The structural setting is more reasonable and practical.

[0088] Specifically, a wiring terminal 600 and an emergency stop switch 700 are also installed on the side wall of the box body 100. There are multiple wiring terminals 600 for connecting to external structures; there is one emergency stop switch 700, which is electrically connected to the control circuit on the circuit board 500 and is used to directly disconnect the power supply of the control circuit in an emergency, thereby quickly stopping the equipment to avoid its abnormal operation.

[0089] The user can disassemble and assemble the wiring terminal 600 and the emergency stop switch 700 through the first opening 102 at the top of the box body 100; Figure 4 , Figure 5 and Figure 8 In order not to affect the user's direct disassembly and installation of the circuit board 500, in this embodiment, the wiring terminal 600 and the emergency stop switch 700 are preferably arranged near the bottom of the box 100. At this time, the mounting frame and the mounting position for mounting the circuit board 500 can be arranged at the corners of the chamber 101 of the box 100, and when the volume of the chamber 101 of the box 100 is constant, sufficient accommodation space is provided for the wiring terminal 600 and the emergency stop switch 700.

[0090] For example, see Figure 4 , Figure 8 and Fig. 9 The second cover body 300 includes a cover plate 310, on which a buttress 311 is provided, which is suitable for pressing the battery pack 400 against the limit plate 110 or the baffle 140, so as to limit the axial displacement of the battery pack 400. Among them, a plurality of blind holes 3111 can be provided on the side of the buttress 311 away from the cover plate 310, which can reduce the weight of the second cover body 300 and reduce the material cost, thereby realizing lightweight production. Preferably, a plate-like structure similar to a reinforcing rib is formed between each two adjacent blind holes 3111, which ensures the structural strength of the buttress 311 to a certain extent and improves the service life of the second cover body 300.

[0091] Preferably, the chamber 101 is provided with a first clamping platform 180 at the edge of the second opening 103, and a second clamping platform 312 is provided at the edge of the platform 311, and a clamping space is formed between the second clamping platform 312 and the cover plate 310, suitable for clamping the first clamping platform 180; at the same time, a docking portion 313 is provided on the side of the cover plate 310 away from the clamping space, and a first fixing hole 3131 is opened on the docking portion 313, and a fastener passes through the first fixing hole 3131 to fix the cover plate 310 to the box body 100. Among them, the fastener can be a screw, a bolt, a rivet, etc., which will not be repeated here, and all are within the protection scope of this application.

[0092] The second cover 300 in this embodiment is fixed at one end by clamping and fixed at the other end by fasteners. When installing the second cover 300, the user first places the first clamping platform 180 in the clamping space, and then fixes it by fasteners to complete the assembly, which is simple and convenient to operate. Conversely, when removing the second cover 300, the user first removes the fasteners, and then removes the first opening platform from the clamping space to complete the disassembly.

[0093] It is understandable that the fixing method adopted in this embodiment is obviously more conducive to the user's disassembly and assembly of the second cover body 300, compared with the structure in which the edges of the second cover body 300 are all locked by fasteners, and the operation is simple, the number of parts is small and not easy to lose. Relatively speaking, compared with the second cover body 300 edges being fixed by snap-fitting, the difficulty of disassembly and assembly of the fixing method adopted in this embodiment is also reduced. The user does not need much effort to clamp the first clamping platform 180 into the clamping space or to detach the first clamping platform 180 from the clamping space, which is easy to operate. Moreover, the edges of the first clamping platform 180 and the second clamping platform 312 will not be worn due to multiple disassembly and assembly, thereby affecting the clamping between the edges of the second cover body 300 and the second opening 103, which effectively prolongs the service life of the box body 100 and the second cover body 300.

[0094] Specifically, the first clamping platform 180 can be arranged at the top of the edge of the second opening 103, or at the side of the edge of the second opening 103. If it is arranged at the top of the edge of the second opening 103, a clearance opening should be provided on the top plate 130 so that the second clamping platform 312 can be inserted into and clamped on the first clamping platform 180; if it is arranged at the side of the edge of the second opening 103, a clearance opening should be provided on the corresponding side plate 120 so that the second clamping platform 312 can be inserted into and clamped on the first clamping platform 180.

[0095] Specifically, the opening size of the second opening 103 should be larger than the outline size of the battery pack 400, and there should be a gap between the side panels 120 and the side walls of the chamber 101 connected to the second opening 103 in the extension direction of the side panels 120, which is more convenient for users to take out the battery pack 400.

[0096] In a preferred embodiment, see Figure 4 and Figures 9 to 11 The first card platform 180 is arranged on the side of the edge of the second opening 103. At this time, the gap formed between the side plate 120 close to the first card platform 180 and the side wall of the chamber 101 connected to the second opening 103 can be used as an escape hole for the second card platform 312 to extend into and be clamped on the first card platform 180.

[0097] In contrast, the gap formed between the other side plate 120 and the side wall of the chamber 101 connected to the second opening 103 can be used as a space for the user to take out the battery pack 400. Fig.10 A protrusion 410 for the user to grasp may be provided at the end of the battery pack 400, so as to further facilitate the user to remove the battery pack 400 from the installation cavity.

[0098] In an exemplary embodiment, the first cover 200 is directly fastened to the first opening 102 of the box body 100 by fasteners. The fasteners may be screws, bolts, rivets, etc., which are not described in detail here and are all within the protection scope of the present application.

[0099] Specifically, see Fig. 9 The second cover body 300 is provided with a vent hole 314 or a vent valve. By providing the vent hole 314 and the vent valve, gas circulation between the inner chamber 101 of the photovoltaic tracker control box and the outside world can be achieved, so that the pressure difference inside and outside the photovoltaic tracker control box is consistent, which is more conducive to the long-term stable operation of the components inside the photovoltaic tracker control box.

[0100] Specifically, the bottom of the photovoltaic tracker control box body 100 is provided with second fixing holes at four corners, and fasteners pass through the second fixing holes to lock the photovoltaic tracker control box to the main shaft. The fasteners may be screws, bolts, rivets, etc., which are not described here one by one, and are all within the protection scope of this application.

[0101] In one example embodiment, see Fig.12 The outer wall of the box body 100 may also be provided with a handle 800 for the user to grasp, so that the user can move or carry the photovoltaic tracker control box.

[0102] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described or recorded in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0103] It should be noted that the above embodiments can be freely combined as needed. The above are only preferred implementations of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application, and these improvements and modifications should also be regarded as the protection scope of the present application.
