Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical lock technology, specifically to a mechanical lock suitable for photovoltaic devices and a photovoltaic device. Background Technology
[0002] As a clean and renewable energy source, solar energy has been increasingly used, especially in the photovoltaic industry that converts solar energy into electricity. With the application of photovoltaics, various problems have also emerged, such as the impact of snow and dust accumulation on photovoltaic panels on power generation efficiency, and the damage caused by strong winds to photovoltaic equipment.
[0003] To address this, some have proposed using tracking photovoltaic (PV) brackets. These brackets allow the PV panels to rotate relative to their fixed bases within the PV system, enabling them to be rotated to a specific angle during adverse weather conditions such as rain, snow, fog, and dust storms, thus mitigating the impact of these conditions on PV power generation efficiency. However, existing PV systems using tracking brackets require the PV panels to be able to rotate around the axis of the drive unit to track the sun or to avoid risks. This necessitates a hinged connection between the PV panel and the output end of the drive unit, resulting in poor stability and making the system highly susceptible to damage from strong winds. Therefore, improving the stability of tracking PV systems is a pressing issue that needs to be addressed. Utility Model Content

[0024] Firstly, the mechanical lock is provided with an outer arc surface on one side of the main body in the first lock body, an insertion slot is arranged on the second lock body, and a first locking part for cooperating with the outer arc surface is arranged in the insertion slot; after the main body is inserted into the insertion slot, i.e. in the locked state, the outer arc surface in the main body is limited by the first locking part, so that the first lock body can only rotate relative to the second lock body along the arc center line of the outer arc surface to make the main body separate from the insertion slot; when the mechanical lock is applied to the foldable photovoltaic device, the first lock body is connected to the first photovoltaic panel through the first connecting part, the second lock body is connected to the second photovoltaic panel or the fixed seat through the second connecting part, when the first photovoltaic panel is driven by the driving shaft to rotate to the position where the main body is inserted into the insertion slot, the first photovoltaic panel is connected to the fixed seat through both the driving shaft and the mechanical lock, so that the connection points of the first photovoltaic panel and the fixed seat are increased, the shaking of the first photovoltaic panel is limited, and the stability of the photovoltaic device is increased; compared with the existing lock, the mechanical lock has a simple structure and low processing cost.
[0025] Secondly, the first limiting part is arranged on the main body, the second limiting part matched with the first limiting part is arranged in the insertion slot, and in the locked state, the first lock body can be limited from undesirably rotating along the arc center line of the outer arc surface in the main body as the axis under the cooperation of the first limiting part and the second limiting part; when the mechanical lock is applied to the foldable photovoltaic device as described above, the first photovoltaic panel can be driven by the driving shaft to rotate along the arc center line of the outer arc surface in the main body as the axis only when it is desired to move, the holding force of the driving shaft on the position state of the first photovoltaic panel when it is undesired to move is reduced, so that the stability of the photovoltaic device is further increased while the self energy consumption of the photovoltaic device is reduced.
[0026] Thirdly, the locking piece is arranged in the insertion slot, the locking piece is connected to the slot wall of the insertion slot through the elastic member, and the locking piece has a resisting force on the main body under the action of the elastic member, so that the main body is prevented from freely separating from the insertion slot, and the stability of the photovoltaic device is increased; at the same time, since the locking piece is a component independent of the second lock body and connected to the second lock body, the sliding groove is arranged in the direction of the main body, and the slot wall on one side of the sliding groove is arranged as the first locking part, i.e. the first locking part is more easily arranged, so that the processing difficulty of the mechanical lock is further reduced.
[0027] Fourthly, by setting a guide part in the first locking part away from the second connecting part, and / or setting a chamfer on the end of the main body away from the first connecting part, the precision requirement of the movement of the main body in the process of inserting the main body into the slot is reduced, i.e. when the mechanical lock is applied to the foldable photovoltaic device as described above, the precision requirement of the driving shaft of the first photovoltaic panel is reduced, thereby reducing the cost of the photovoltaic device.

[0046] In the description of the present application, if there are terms such as "A is connected to B in a rotatable manner" and the like, it means that A is directly or indirectly connected to B, and A can rotate relative to B.
[0047] In the description of the present application, reference to "one embodiment" or "some embodiments" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the application. The appearances of the phrases "in one embodiment" or "in some embodiments" in various places in the specification are not necessarily all referring to the same embodiment, however, but can refer to one or more but not all embodiments of the application, unless otherwise specified.
[0048] As shown in Figures 1 to 4 As a first aspect of the present embodiment, a mechanical lock 100 suitable for photovoltaic devices is disclosed, comprising: a first lock body 1, the first lock body 1 comprising a main body 11 and a first connecting part 12 provided at one end of the main body 11 for connecting with the outside, one side surface of the main body 11 being an outer arc surface 112; a second lock body 2, one end of the second lock body 2 being provided with a slot 21 capable of accommodating the main body 11, one side slot wall of the slot 21 being provided with a first locking part for cooperating with the outer arc surface 112, and the other end being provided with a second connecting part 22 for connecting with the outside; in the locked state, the main body 11 is inserted into the slot 21, and under the cooperation of the first locking part and the outer arc surface 112, the first lock body 1 can only rotate relative to the second lock body 2 along the arc center line of the outer arc surface 112 to make the main body 11 disengage from the slot 21.
[0049] It should be noted that in the present embodiment, the first lock body 1 comprises a main body 11 and a first connecting part 12 provided at one end of the main body 11 for connecting with the outside, wherein the main body 11 and the first connecting part 12 can be fixedly connected to constitute the first lock body 1 as two independent parts, or can be integrally formed as a single part to constitute the first lock body 1 as shown in Figures 1 to 4
[0050] Similarly, the other end of the second lock body 2 is provided with a second connecting part 22 for connecting with the outside, and the second connecting part 22 can be an independent part independent of the part where the slot 21 is provided, or the second lock body 2 can be an integrally formed single part.
[0051] It should be noted that in the present embodiment, the first lock body 1 can only rotate relative to the second lock body 2 along the arc center line of the outer arc surface 112 as the axis to make the main body 11 separate from the insertion slot 21, and under the cooperation of the first locking part and the outer arc surface 112, the first lock body 1 cannot move relative to the second lock body 2 in any other direction. Since the mechanical lock 100 proposed in the present embodiment can rotate relative to the components connected to the first lock body 1 and the components connected to the second lock body 2 when in use, and only when the arc center line of the outer arc surface 112 is used as the axis to rotate relative to the two components, the main body 11 can be inserted into the insertion slot 21, that is, when the main body 11 is inserted into the insertion slot 21, the components connected to the first lock body 1 and the components connected to the second lock body 2 are connected not only by the mechanical lock 100 but also by the driving shaft that can rotate relative to the two components. Therefore, the first locking part cooperating with the outer arc surface 112 can adopt the following designs, including but not limited to the following designs:
[0052] The first, as the first embodiment of the present embodiment, as shown in Figure 1 The first locking part is a side slot wall of the insertion slot 21. It should be noted that the slot wall as the first locking part refers to the wall surface or part of the wall surface that can cooperate with the outer arc surface 112. Therefore, the wall surface of the slot wall needs to be set as an inner arc surface, and the arc radius of the inner arc surface is not greater than the arc radius of the outer arc surface 112, that is, when the arc radii of the two are equal, the outer arc surface 112 of the main body 11 forms a surface contact with the slot wall as the first locking part, and when the arc radius of the inner arc surface is less than the arc radius of the outer arc surface 112, the slot wall as the first locking part can form contact with the outer arc surface 112 of the main body 11 at least at two points, thereby realizing the limitation that the first lock body 1 can only rotate relative to the second lock body 2 along the arc center line of the outer arc surface 112 as the axis to make the main body 11 separate from the insertion slot 21.
[0053] The second, as the second embodiment of the present embodiment, as shown in Figure 2 and Figure 3 The first locking part is at least two groups of pulleys 4, and a plurality of groups of the pulleys 4 are connected to the slot wall of the insertion slot 21 in sequence in the direction in which the main body 11 is inserted into the insertion slot 21. It should be noted that in order to ensure that the pulleys 4 as the first locking part contact the outer arc surface 112 at least at two points in the direction in which the main body 11 separates from the insertion slot 21, the number of pulleys 4 is at least two groups; at the same time, in order to ensure that the pulleys 4 have the function of the first locking part, according to the arc radius of the outer arc surface 112, a certain distance needs to be maintained between the two groups of pulleys 4. At the same time, the pulleys 4 can also reduce the friction between the first locking part and the outer arc surface 112 of the main body 11 during the process of inserting the main body 11 into the insertion slot 21, and improve the smoothness of the process of inserting the main body 11 into the insertion slot 21.
[0054] Thirdly, as the third embodiment of the present application, as shown in Figure 2 and Figure 3 the first locking part is a slide slot 54, one side wall of the slide slot 54 is the first locking part.
[0055] It should be noted that the one side wall of the slide slot 54 as the first locking part is an inner arc surface matched with the outer arc surface 112, and the arc radius of the inner arc surface is also not greater than the arc radius of the outer arc surface 112, that is, the outer arc surface 112 of the main body 11 and the one side wall of the slide slot 54 as the first locking part can form a surface contact matching, or the one side wall of the slide slot 54 as the first locking part and the outer arc surface 112 form at least two points of contact.
[0056] It should also be noted that in order to ensure that the main body 11 can be inserted into the slide slot 54, the slide slot 54 extends at least in the direction of the slot opening of the slot 21 and penetrates the lock piece 5.
[0057] It should be noted that in the present application, only the above three embodiments are simply listed, and it is not limited to the above three embodiments, so that only the first locking part is simply changed, but the function is the same as the above three embodiments disclosed in the present application, and it should be considered to be within the protection scope of the present application, and it should also be noted that the above three embodiments can be implemented alone or in any combination.
[0058] Further, in the present application, in the embodiment with the lock piece 5, when the one side wall of the slide slot 54 is the first locking part, in order to prevent the first lock body 1 and the second lock body 2 from being able to rotate freely around the arc center line of the outer arc surface 112, and to increase the resistance of the main body 11 being pulled out of the slide slot 54, as shown in Figure 2 and Figure 3 a resilient member 3 is arranged in the mechanical lock 100, and the lock piece 5 is connected to the slot wall of the slot 21 through the resilient member 3.
[0059] Further, in the present application, in the embodiment with the lock piece 5, when the one side wall of the slide slot 54 is the first locking part, in order to make the force more balanced when the main body 11 is pulled out of the slide slot 54, as shown in Figure 2 and Figure 3 the lock piece 5 includes a first lock piece 51 and a second lock piece 52, the first lock piece 51 and the second lock piece 52 are arranged opposite to each other and abut against both sides of the main body 11.
[0060] It should be noted that in the present embodiment, in the non-locked state, the first lock body 1 and the second lock body 2 are independently connected to two components that can be driven to rotate relative to each other, in order to facilitate the insertion of the main body 11 into the slot 21 and reduce the precision requirement of the movement between the two components driven to rotate relative to each other, at least one of the following designs can be used:
[0061] First, as shown in Figure 2 and Figure 3 , the mechanical lock 100 further comprises a guide portion provided in the slot 21 or the first locking portion away from one end of the second connecting portion 22. That is, when one side of the slot wall of the slot 21 is the first locking portion or the pulley 4 is the first locking portion, the first guide portion 211 is the chamfer 113 at the slot opening of the slot 21; when the lock plate 5 is provided, and one side of the slot wall of the sliding groove 54 on the lock plate 5 is the first locking portion, the sliding groove 54 is gradually opened at one end of the slot opening of the slot 21 to form the second guide portion 55. The extension segment of the slot opening of the sliding groove 54 extending to one end of the sliding groove 54 away from the main body 11 is the second guide portion 55.
[0062] Second, as shown in Figure 2 and Figure 3 , the main body 11 is provided with a chamfer 113 away from one end of the first connecting portion 12.
[0063] It should be noted that whether the guide portion is provided, or the chamfer 113 is provided, or both the guide portion and the chamfer 113 are provided, the precision requirement of the movement of the main body 11 during the insertion of the main body 11 into the slot 21 is reduced.
[0064] It should be noted that in the present embodiment, in order to facilitate the arrangement of the slot 21 and reduce the cost, as shown in Figures 1 to 3 , the main body 11 is in a strip shape, and the slot 21 or the sliding groove 54 matched therewith is also in a strip shape.
[0065] It should be noted that in the present embodiment, in order to increase the stability of the connection between the first lock body 1 and the second lock body 2 and prevent the first lock body 1 from freely separating from the second lock body 2, a first limiting portion 111 is provided on the main body 11, and a second limiting portion matched with the first limiting portion 111 is provided in the slot 21, and in the locked state, the second limiting portion is matched with the first limiting portion 111.
[0066] By the cooperation between the first limiting portion 111 and the second limiting portion, the movement of the first lock body 1 relative to the second lock body 2 along the center line of the outer arc surface 112 as the axis to separate the main body 11 from the slot 21 is limited.
[0067] Among the first limiting part 111 and the second limiting part, one can be a protrusion, and the other can be a protrusion or a recess matched with the protrusion. For more convenient description, as shown in Figures 1 to 3 the first limiting part 111 is a recess arranged on both sides of the main body 11. When the side slot wall of the insertion slot 21 is the first locking part, the two side slot walls adjacent to the side slot wall are provided with the first protrusion 212 matched with the recess. When only the pulley 4 is the first locking part, the first protrusion 212 can also be arranged on the two end slot walls of the insertion slot 21 to match the first limiting part 111. When the lock sheet 5 is arranged, and the sliding slot 54 is arranged on the lock sheet 5, and the side slot wall of the sliding slot 54 is the first locking part, the second protrusion 53 matched with the recess can also be arranged on the slot bottom of the sliding slot 54.
[0068] It should be noted that in the embodiment, although only the first limiting part 111 as a recess arranged on both sides of the main body 11 is described in detail, it should be understood that the first limiting part 111 can also be a protrusion, and the second limiting part is a recess matched with the protrusion. It should also be noted that the first limiting part 111 can also be arranged on the outer arc surface 112 or the surface of the main body 11 opposite to the outer arc surface 112. At this time, the setting position of the second limiting part only needs to be adjusted accordingly.
[0069] It should be noted that in the embodiment, in the locked state, the other surface of the main body 11 opposite to the outer arc surface 112 can be in contact with the slot wall of the insertion slot 21 or the pulley 4 or the side slot wall of the sliding slot 54 arranged on the lock sheet 5, or not in contact.
[0070] As shown in Figure 4 as a second aspect of the embodiment, a photovoltaic device is disclosed, which comprises the mechanical lock 100 suitable for the photovoltaic device as described above. One of the first lock body 1 and the second lock body 2 is connected with the photovoltaic panel 300 in the photovoltaic device, and the other is connected with the fixing seat 200 in the photovoltaic device.
[0071] The advantage of the embodiment is that under the action of the mechanical lock 100, the stability of the photovoltaic device is increased, and the cost of the photovoltaic device is reduced. At the same time, the mechanical lock 100 has a simple structure and low processing cost.
[0072] Firstly, the mechanical lock 100 provided in the embodiment sets the side of the main body 11 of the first lock body 1 as an outer arc surface 112, sets the first locking part for cooperating with the outer arc surface 112 in the insertion slot 21 of the second lock body 2, and limits the outer arc surface 112 of the main body 11 by the first locking part after the main body 11 is inserted into the insertion slot 21, i.e. in the locked state, so that the first lock body 1 can only rotate relative to the second lock body 2 along the arc center line of the outer arc surface 112 to make the main body 11 separate from the insertion slot 21. When the mechanical lock 100 provided in the embodiment is applied to the foldable photovoltaic device, the first lock body 1 is connected to the first photovoltaic panel 300 through the first connecting part 12, and the second lock body 2 is connected to the second photovoltaic panel 300 or the fixed seat 200 through the second connecting part 22. When the first photovoltaic panel 300 is driven by the driving shaft to rotate to the position where the main body 11 is inserted into the insertion slot 21, the first photovoltaic panel 300 is connected to the fixed seat 200 through both the driving shaft and the mechanical lock 100, so that the connection points of the first photovoltaic panel 300 and the fixed seat 200 are increased, the shaking of the first photovoltaic panel 300 is limited, and the stability of the photovoltaic device is increased. Compared with the existing lock, the mechanical lock 100 provided in the embodiment has a simple structure and low processing cost.
[0073] Secondly, the first limiting part 111 is arranged on the main body 11, and the second limiting part cooperating with the first limiting part 111 is arranged in the insertion slot 21. In the locked state, the first lock body 1 can be limited from undesirably rotating along the arc center line of the outer arc surface 112 of the main body 11 as the axis by the cooperation of the first limiting part 111 and the second limiting part. When the mechanical lock 100 provided in the embodiment is applied to the foldable photovoltaic device as described above, the first photovoltaic panel 300 can be driven by the driving shaft to rotate along the arc center line of the outer arc surface 112 of the main body 11 as the axis only when the movement of the first photovoltaic panel 300 is desired, so that the holding force of the driving shaft on the position state of the first photovoltaic panel 300 when the movement of the first photovoltaic panel 300 is not desired is reduced, thereby further increasing the stability of the photovoltaic device while reducing the self-energy consumption of the photovoltaic device.
[0074] Thirdly, the lock piece 5 is arranged in the insertion slot 21, the lock piece 5 is connected to the slot wall of the insertion slot 21 through the elastic member 3, and the lock piece 5 has a resisting force on the main body 11 under the action of the elastic member 3, so that the main body 11 is prevented from freely separating from the insertion slot 21, and the stability of the photovoltaic device is increased. Since the lock piece 5 is a component independent of the second lock body 2 and connected to the second lock body 2, the sliding groove 54 is arranged in the direction of the main body 11, the slot wall on one side of the sliding groove 54 is set as the first locking part, i.e. the first locking part is more easily arranged, and the processing difficulty of the mechanical lock 100 provided in the embodiment is further reduced.
[0075] Fourthly, by setting a guide part in the first locking part away from the second connecting part 22, and / or setting a chamfer 113 in the end of the main body 11 away from the first connecting part 12, the precision requirement of the movement of the main body 11 during the process of inserting the main body 11 into the slot 21 is reduced, i.e. the precision requirement of the driving shaft of the first photovoltaic panel 300 is reduced when the mechanical lock 100 proposed in this embodiment is applied to the foldable photovoltaic device as described above, thereby reducing the cost of the photovoltaic device.
[0076] Fifthly, a pulley 4 is set in the inner wall of the slot 21, which is used as the first locking part or a component of the first locking part, which can not only ensure that the first lock body 1 can only rotate relative to the second lock body 2 along the center line of the outer arc surface 112 to make the main body 11 disengage from the slot 21, but also reduce the friction between the first locking part and the outer arc surface 112 of the main body 11 during the process of inserting the main body 11 into the slot 21 through the rolling of the pulley 4, thereby improving the smoothness of the process of inserting the main body 11 into the slot 21.
