Description

Technical Field

[0001] This utility model relates to the field of solar energy, and in particular to a clutch and a photovoltaic device. Background Technology

[0002] To save on the cost of photovoltaic devices and increase their wind resistance and disaster avoidance capabilities, a clutch is provided in a foldable photovoltaic tracking device disclosed in the applicant's earlier application (publication number CN220964767U). By switching the clutch state, a set of power units can either drive two photovoltaic panels to rotate synchronously to track sunlight, or drive one photovoltaic panel to rotate relative to the other, causing the two panels to fold.

[0003] In a clutch, the key component for switching states—the pawl (referred to as the locking block in this invention)—usually requires machining. The manufacturing process of machined parts relies primarily on precision machinery and cutting tools, removing excess material to form the desired shape. Due to the relative complexity of this process, the production cost of the pawl is high and its efficiency is low. Therefore, to improve the economic efficiency of the clutch, how to design and configure the clutch's state-switching components has become an urgent problem to be solved. Utility Model Content

[0004] First, this utility model proposes a clutch to reduce the cost of existing clutches. Second, this utility model also discloses a photovoltaic device.

[0005] As a first aspect of this utility model, a clutch is proposed, comprising:

[0006] A first component, the first component including a first body and a first joint;

[0007] The second component includes a second body, a locking block, and an elastic element.

[0008] The first body and the second body are coaxially arranged, and the first component and the second component are rotatably connected through the cooperation of the first body and the second body;

[0009] The locking block is hinged to the second main body, and the locking block includes a bottom plate and a side plate, which are fixedly connected.

[0010] The locking block is provided with a second engaging part that cooperates with the first engaging part. When the second engaging part is in contact with the first engaging part, the clutch is in an engaged state. When the second engaging part is disengaged from the first engaging part, the clutch is in a disengaged state.

[0011] The elastic element is connected to the locking block, and the elastic element is used to force the locking block into an engaged or disengaged state.

[0012] Preferably, a space is provided between the base plate and the side plate to accommodate the elastic element.

[0013] Preferably, the elastic element is a torsion spring, which is sleeved on the locking block and hinged to the hinge shaft of the second body.

[0014] Preferably, the base plate is provided with a pushing part, and in the engaged state, when the pushing part is subjected to an external force, the locking block rotates toward the disengaged state.

[0015] Preferably, the clutch further includes a power source, and the second body is further provided with a drive chamber, wherein the power source is located in the drive chamber.

[0016] In some embodiments, a first sensor is also included, and the push part is provided with a first detection position for cooperating with the first sensor. When the first sensor is triggered by the first detection position, the clutch is in a disengaged state; and / or, a second sensor is also included, and the push part is provided with a second detection position for cooperating with the second sensor. When the second sensor is triggered by the second detection position, the clutch is in an engaged state.

[0017] Preferably, the clutch further includes a third sensor, and the push part is provided with a third detection position for cooperating with the third sensor, and the third detection positions are arranged in pairs on the push part.

[0018] Preferably, the second joint includes a first mating piece disposed on the base plate and / or a second mating piece disposed on the side plate.

[0019] Preferably, the axis of the second joint coincides with the axis of the hinge axis of the locking block hinged to the second body.

[0020] Preferably, the base plate is provided with a first connecting part, and the side plate is provided with a second connecting part, and the first connecting part and the second connecting part are connected.

[0021] Preferably, the base plate is U-shaped, and the side plate is provided with a fixing position, through which the base plate and the side plate are fixedly connected.

[0022] As a second aspect of this utility model, a photovoltaic device is proposed, including a powertrain and two photovoltaic panels, and also including the aforementioned clutch, wherein the clutch is connected to the output end of the powertrain through the first component or the second component;

[0023] The first main body is further provided with a first mounting part, and the second main body is further provided with a second mounting part. The first mounting part is fixedly connected to a photovoltaic panel, and the second mounting part is fixedly connected to another photovoltaic panel.

[0024] The beneficial effects of this utility model are as follows:

[0025] 1. The locking block consists of a base plate and side plates, at least one of which is a sheet metal part. Sheet metal parts are relatively simple to manufacture and have lower costs. Moreover, locking blocks composed of sheet metal parts have advantages over parts cut by machining tools, such as lighter weight and greater flexibility.

[0026] 2. The elastic element is a torsion spring, which is set at the hinge position between the two sheet metal parts in the lock block. In other words, the two sheet metal parts are reserved for the elastic element, which integrates the lock block structure and makes its structure more compact and reasonable.

[0027] 3. In the embodiment where the clutch is equipped with a sensor, the sensor, in conjunction with the detection position in the locking block, can determine the rotational position of the locking block, thereby judging the working state of the clutch. When clutches are used in pairs and mirror-image positioned in different locations (such as in the photovoltaic device proposed in this utility model), conventional solutions require machining locking blocks with detection positions at different locations for the two types of clutches. This not only increases the variety of clutch parts but also raises processing costs. Therefore, this solution symmetrically sets the two detection positions in the locking block, allowing a single locking block component to meet the needs of clutches in different positions, effectively reducing processing costs and improving production efficiency.

[0046] The present invention will be further described in detail below with reference to the accompanying drawings.

[0047] This specific implementation method first proposes a method such as Figures 1 to 4The clutch 1 shown includes a first component 11 and a second component 12. The first component 11 includes a first body 111 and a first engaging portion 112; the second component 12 includes a second body 121, a locking block 13, and an elastic element. The first body 111 and the second body 121 are coaxially arranged, and the first component 11 and the second component 12 are rotatably connected through the engagement of the first body 111 and the second body 121. The locking block 13 is hinged to the second body 121, as shown... Figure 5 and Figure 6 As shown, the locking block 13 includes a base plate 131 and a side plate 132, which are fixedly connected. The locking block 13 has a second engaging portion 138 that mates with the first engaging portion 112. When the second engaging portion 138 contacts and engages with the first engaging portion 112, the clutch 1 is in an engaged state; when the second engaging portion 138 disengages from the first engaging portion 112, the clutch 1 is in a disengaged state. An elastic element is connected to the locking block 13 and is used to force the locking block 13 into either the engaged or disengaged state.

[0048] It should be noted that the first component 11 can be either integrally formed or composed of multiple detachable and fixedly connected parts.

[0049] The base plate 131 and / or the side plate 132 are sheet metal parts. Sheet metal parts have a simpler processing technology and lower cost. Moreover, the locking block 13 composed of sheet metal parts has advantages such as lighter weight and greater flexibility compared to parts cut by machining tools.

[0050] The locking block 13 and the second body 121 can be connected either by a hinge shaft integrally set on the base plate 13 and / or the side plate 132 and the second body 121, or by a hinge shaft independent of the base plate 13, the side plate 132 and the second body 121. In this case, the hinge shaft needs to be connected to the base plate 13 and the side plate 132 or to the second body 121 first, so as to achieve the hinge connection between the locking block 13 and the second body 121.

[0051] The locking block 13 is hinged to the second body 121 via a hinge shaft 123. The hinge shaft 123 can be integrally set on the base plate 131, side plate 132 or the second body 121, or it can be independent of the base plate 131, side plate 132 or the second body 121 and connected as a separate component. This will not be elaborated further here.

[0052] exist Figure 5 and Figure 6As shown, in the first embodiment of the locking block, a space for accommodating an elastic element is provided between the base plate 131 and the side plate 132. Furthermore, when the elastic element is a torsion spring 124, the torsion spring 124 is sleeved on the hinge shaft 123 of the locking block 13, which is hinged to the second body 121, improving the overall integration of the locking block 13 and making its structure more rational. In addition, the elastic element can also be a metal spring or a non-metallic elastic component such as rubber.

[0053] exist Figure 3 and Figure 4 In some embodiments shown, the base plate 131 is provided with a pushing part 133, which is used to connect to an external power source. When the elastic member forces the locking block 13 into the engaged state, the external power source drives the locking block 13 to rotate towards the disengaged state. When the elastic member forces the locking block 13 into the disengaged state, the external power source can drive the locking block 13 to rotate towards the engaged state. The pushing part 133 can also be provided on the side plate 132, or simultaneously on the base plate 131 and the side plate 132, to further improve strength.

[0054] In some embodiments, an unlocking module 14 is also included, which is used to drive the pushing part 133 to engage or disengage the first engaging part 112 and the second engaging part. The unlocking module 14 can be mechanical or hydraulic / pneumatic. Figure 4 In some embodiments shown, the unlocking module 14 includes a geared motor 141, a lead screw 142, and a lead screw nut 143. The lead screw nut 143 has a protrusion that cooperates with the pushing part 133. The geared motor 141 drives the lead screw 142 to rotate, causing the lead screw nut 143 to move linearly along the lead screw 142, and drives the pushing part 133 to move through the protrusion.

[0055] exist Figures 3 to 5 In some embodiments shown, the second body 121 further includes a drive chamber 125 for accommodating the power source (unlocking module 14), and the drive chamber 125 has an opening facing the locking block 13. A pushing part 133 extends from the opening into the drive chamber 125, and the pushing part 133 has a first waterproof part 136. The opening has a second waterproof part 1251 that cooperates with the first waterproof part 136. Through the cooperation of the first waterproof part 136 and the second waterproof part 1251, the locking block 13 and the pushing part 133 can work normally while preventing large gaps from being exposed. In humid environments, this prevents unnecessary moisture from entering and disrupting the normal operation of the parts inside the drive chamber 125, thus improving the stability of the clutch 1.

[0056] The second joint can be provided on either the base plate 131 or the side plate 132, or it can be provided on both the base plate 131 and the side plate 132. For example... Figure 6As shown, in some embodiments, the base plate 131 is provided with a first mating piece 1311, the side plate 132 is provided with a second mating piece 1321, and the second joint is composed of the first mating piece 1311 and the second mating piece 1321. Furthermore... Figure 5 and Figure 6 In the middle, the first mating piece 1311 and the second mating piece 1321 are also located at the connection between the bottom plate 131 and the side plate 132. The second joint in the locking block 13 is composed of the first mating piece 1311 and the second mating piece 1321, making the connection point a functional part and simplifying the overall structure of the locking block 13.

[0057] In some embodiments, the first mating piece 1311 and the second mating piece 1321 are arc-shaped. Furthermore, as... Figure 5 As shown, the second joint, composed of the first mating piece 1311 and the second mating piece 1321, is also arc-shaped. Figure 3 The shape of the first engagement portion 112 shown is similar to the shape of the inclined groove, which matches the arc-shaped surface. The arc-shaped second engagement portion, after engaging with the first engagement portion 112 in the corresponding engagement state, makes it difficult for the first body 111 and the locking block 13 to rotate in the opposite direction, thereby making the one-way locking of the clutch 1 more stable.

[0058] In some implementations, such as Figure 3 As shown, the axis of the arc-shaped second joint coincides with the axis of the hinge shaft 123 of the locking block 13 hinged to the second body 121.

[0059] In some embodiments, the base plate 131 is provided with a first connecting portion 1312, and the side plate 132 is provided with a second connecting portion 1322, and the first connecting portion 1312 and the second connecting portion 1322 are connected together. The base plate 131 and the side plate 132 can be fixedly connected by welding or drilling and threading the first connecting portion 1312 and the second connecting portion 1322.

[0060] In some embodiments, a first anti-detachment portion 134 is provided between the first mating piece 1311 and the second mating piece 1321, and a second anti-detachment portion 135 is provided between the first connecting portion 1312 and the second connecting portion 1322. For example... Figure 7As shown, in the second embodiment of the locking block, both the first anti-detachment part 134 and the second anti-detachment part 135 are disposed on the base plate 131. The first anti-detachment part 134 is integrally disposed with the first mating piece 1311 and forms a groove for accommodating the second mating piece 1321. The side plate 132 is connected to the base plate 131 via a hinge shaft 123, and the second mating piece 1321 is inserted into the groove. At this time, the locking block 13 becomes a whole when moving around the hinge shaft 123, and the base plate 131 and the side plate 132 can only be separated by moving away from each other in the axial direction of the hinge shaft 123. Furthermore, the second anti-detachment part 135 disposed on the first connecting part 1312 is disposed in the same manner. The first anti-detachment part 134 and the second anti-detachment part 135 can also be disposed on the side plate 132, or a combination thereof, which will not be elaborated further here.

[0061] The arrangement of the first anti-detachment part 134 and the second anti-detachment part 135 allows the base plate 131 and the side plate 132 to be fixedly connected in the rotating state, while also allowing the component to be disassembled and replaced when a problem occurs, thus improving the utilization rate of the components.

[0062] In some embodiments, the base plate 131 and the side plate 132 are fixedly connected by welding. The welding position can be either the first connecting part 1312 and the second connecting part 1322, or simultaneously at the first mating piece 1311, the second mating piece 1321, the through hole, and the hinge shaft 123.

[0063] In some embodiments, a sensor is also included, which may be a Hall sensor, an infrared sensor, etc. When the sensor is an electromagnetic Hall sensor, the sensor includes a magnetic induction circuit and a permanent magnet. The magnetic induction element is disposed on the second main body 121, and the permanent magnet is disposed on the locking block 13. The sensor is used to detect the rotational position of the locking block 13, and obtains the specific state of the clutch 1 through its rotational position. The sensor composed of a magnetic induction circuit and a permanent magnet avoids the reliability degradation caused by wear, loosening, and other problems of traditional mechanical contact sensors because the electromagnetic position sensor does not need to be in direct contact with the measured object during the measurement process, thus improving the flexibility and convenience of measurement.

[0064] In some implementations, when the pusher 133 is used in conjunction with the sensor, there are three scenarios:

[0065] In the first case: the clutch 1 includes a first sensor, and the push part 133 is provided with a first detection position for cooperating with the first sensor. When the first sensor is triggered by the first detection position, the clutch 1 is in the disengaged state.

[0066] The second scenario: The clutch 1 includes a second sensor, and the push part 133 is provided with a second detection position for cooperating with the second sensor. When the second sensor is triggered by the second detection position, the clutch 1 is in the engaged state.

[0067] The third scenario: The clutch 1 includes a first sensor and a second sensor. The push part 133 is provided with a first detection position for cooperating with the first sensor. The push part 133 is also provided with a second detection position for cooperating with the second sensor. When the first sensor is triggered by the first detection position, the clutch 1 is in a disengaged state. When the second sensor is triggered by the second detection position, the clutch 1 is in an engaged state.

[0068] like Figure 8 and Figure 9 The diagram shows a third embodiment of the locking block 13, which differs from the first and second embodiments in that: 1. The second joint 138 is directly mounted on the base plate 131, consisting only of the base plate 131. 2. The side plate 132 has at least one fixing position 137, which is fixedly connected to the base plate 131. Furthermore, when the clutches 1 are used in pairs and mirror-image positioned in different locations (as in the photovoltaic device proposed in this invention), conventional solutions require machining locking blocks 13 with the third detection positions 139 at different positions for the two clutches 1. This not only increases the variety of clutch 1 parts but also raises processing costs. Therefore, this solution symmetrically arranges the two third detection positions 139 in the locking block 13, allowing a single locking block 13 component to meet the needs of clutches 1 in different positions, effectively reducing processing costs and improving production efficiency.

[0069] Regarding the specific shapes of the side plate 132 and the bottom plate 131, in this embodiment, both the side plate 132 and the bottom plate 131 are L-shaped or at least one is U-shaped (or concave), such as... Figure 5 and Figure 6 In the first embodiment of the lock block 13 shown, both the side plate 132 and the bottom plate 131 are U-shaped; Figure 8 and Figure 9 In the third embodiment of the locking block 13 shown, the base plate 131 is U-shaped, and the side plate 132 is a planar structure that mates with it. In this embodiment, the structure of the base plate 131 and the side plate 132 has good utilization, with no extra redundant parts, resulting in higher economic efficiency. Similarly, the hinge shaft 123 can be fixedly connected to the side plate 132 and / or the base plate 131, or hinge holes that mate with the hinge shaft 123 can be provided on the side plate 132 and / or the base plate 131.

[0070] As a second aspect of this specific embodiment, a photovoltaic device is proposed, including the aforementioned clutch 1, a powertrain 2, and two photovoltaic panels 3. The clutch 1 is fixedly connected to the output end of the powertrain 2 via the first component 11 or the second component 12. The first body 111 is provided with a first mounting part 113, and the second body 121 is provided with a second mounting part 122. The first component 11 is connected to a photovoltaic panel 3, and the second component 12 is connected to a photovoltaic panel 3.

[0071] In such Figure 3 In some embodiments shown, the inner circumferential surface of the first body 111 is provided with splines 1111, through which the clutch 1 is mounted on the powertrain 2, thereby making the connection between the clutch 1 and the powertrain 2 more reliable and able to withstand greater torque. In other embodiments, the first body 111 is provided with a keyway, through which the clutch 1 and the powertrain 2 are connected by a key connection. Furthermore, the connection between the clutch 1 and the powertrain 2 can also be achieved through welding, threaded connection, etc., which will not be elaborated upon here.

[0072] In such Figure 10 and Figure 11 In the illustrated embodiment, the photovoltaic device further includes a column 4. The fixing part of the power assembly 2 is fixedly connected to the column 4. Two sets of clutches 1, as proposed in this embodiment, are located at the two ends of the output end of the power assembly 2. The first mounting part 113 and the second mounting part 122 are respectively fixedly connected to two photovoltaic panels 3. The first main body 111 is also provided with a first abutting part, and the second main body 121 may also have a second abutting part 1211. When the photovoltaic device tracks sunlight, the locking block 13 and the first engaging part 112 engage, and the first abutting part and the second abutting part 1211 abut against each other, so that the first component 11 and the second component 12 form a whole. The power assembly 2 drives the two photovoltaic panels 3 to rotate synchronously through the clutches 1. When the photovoltaic device needs to be folded up, the locking block 13 and the first engaging part 112 separate, and the first abutting part and the second abutting part also separate. The power assembly 2 drives the first component 11 to rotate. At this time, the second component 12 cannot rotate synchronously with the first component 11. Therefore, the first component 11 rotates relative to the second component 12 until the two are close together and folded, so that the photovoltaic device reaches the folded state.
