[0027] The advantages of this invention are: the connection between the input end of the transmission component and the output shaft of the power source is simpler and faster, the structure is simple, and the cost is reduced.

[0028] First, when using the transmission connector proposed in this utility model to connect the input end of the transmission component to the output shaft of the power source, the transmission connector only needs to be coaxially connected to the first connecting part through the first insertion slot, and the power source is inserted into the second insertion slot through the second connecting part. Alternatively, the transmission connector can be coaxially connected to the second connecting part through the second insertion slot, and the transmission component can be inserted into the first insertion slot through the first connecting part.

[0029] Meanwhile, the transmission connector in the powertrain proposed by this utility model is an independent whole. It only needs to be machined at both ends to form insertion slots for mating with the first connecting part and the second connecting part, which not only facilitates processing and reduces processing costs, but also makes the structure of the transmission connector simpler.

[0030] Secondly, by designing at least one of the first and second connecting parts as a wrench ball head, and after it mates with the corresponding insertion slot on the transmission connector, the problem of misalignment between the input end of the transmission component and the output shaft of the power source caused by machining errors or assembly errors is also eliminated.

[0031] Third, when only one of the first connecting part and the second connecting part is in the shape of a wrench ball, the other part can adopt a style that is easier to process and more cost-effective. For example, a keyway can be provided on the outer peripheral surface of the other part, or a through-hole can be provided on the transmission connecting part that cooperates with the other part, thereby further saving processing costs.

[0032] Fourth, guide grooves can be provided at the openings of both the first and second insertion slots on the transmission connector, or a chamfer can be provided at the connection between the end face and the circumference of the one that is not shaped like a wrench ball head in the first and second connecting parts.

[0050] like Figures 1 to 5As shown, in the first aspect of this embodiment, a powertrain includes:

[0051] The transmission assembly 1 includes an input end 12, wherein the input end 12 is provided with a first connecting portion 121;

[0052] The power source 3 includes an output shaft 31, wherein the output shaft 31 is provided with a second connecting part 311;

[0053] The transmission connector 4 has a first insertion groove 41 at one end that mates with the first connecting part 121, and a second insertion groove 42 at the other end that mates with the second connecting part 311.

[0054] The transmission connector 4 is coaxially connected to the first connecting part 121 through the first insertion slot 41, and the power source 3 is inserted into the second insertion slot 42 through the second connecting part 311. Alternatively, the transmission connector 4 is coaxially connected to the second connecting part 311 through the second insertion slot 42, and the transmission assembly 1 is inserted into the first insertion slot 41 through the first connecting part 121.

[0055] The power source 3 drives the transmission connector 4 and the input end 12 to rotate synchronously via the output shaft 31.

[0056] It should be noted that the synchronous rotation of the output shaft 31 driving the transmission connector 4 and the input end 12 means that the output shaft 31 drives the input end 12 to rotate through the transmission connector 4, and does not mean that the output shaft 31 and the input end 12 rotate at the same speed. When the power source 3 includes a connected motor and a reducer, the output shaft 31 refers to the output shaft 31 of the reducer.

[0057] It should be noted that in this embodiment, the first connecting part 121 is used to connect one end of the transmission connector 4. When the first connecting part 121 is inserted into the first insertion slot 41, the input end 12 can rotate synchronously with the transmission connector 4. The second connecting part 311 is used to connect the other end of the transmission connector 4. When the second connecting part 311 is inserted into the second insertion slot 42, the output shaft 31 of the power source 3 can rotate synchronously with the transmission connector 4.

[0058] It should be noted that in this embodiment, the output shaft 31 of the power source 3 may be misaligned with the input end 12 due to factors such as installation errors, temperature changes during operation, and deformation under load. To solve this problem, at least one of the first connecting part 121 and the second connecting part 311 can be shaped like a wrench ball head. For the sake of brevity, this embodiment will only describe the first connecting part 121 as being wrench ball head shaped, as detailed below. Figures 2 to 6As shown, but not only the first connecting part 121 is ball-head shaped, the wrench ball-head shape can be hexagonal ball-head, and the first insertion groove 41 that mates with the hexagonal ball-head shaped first connecting part 121 is an internal hexagonal groove.

[0059] It should be noted that the internal hexagonal groove in this embodiment includes an internal hexagonal straight groove and an internal hexagonal ball groove.

[0060] Furthermore, in this embodiment, when only the first connecting part 121 is wrench-shaped, the connection method between the second connecting part 311 and the second insertion slot 42 includes, but is not limited to, the following:

[0061] First, when the cross-section of the second connecting part 311 along the axis of the output shaft 31 is a perfect circle, a set screw is provided on the groove wall of the second insertion groove 42 that mates with the second connecting part 311. The set screw is used to press the second connecting part 311, so that the second connecting part 311 and the second insertion groove 42 maintain a stable connection.

[0062] Second, when the cross-section of the second connecting part 311 along the axis of the output shaft 31 is a perfect circle, such as Figure 2 , Figures 4 to 5 As shown, the outer surface of the second connecting part 311 is provided with a keyway.

[0063] Third, when the cross-section of the second connecting part 311 along the axis of the output shaft 31 is non-circular, for example: elliptical, semi-circular and square, etc.

[0064] It should be noted that by designing one of the first connecting part 121 and the second connecting part 311 as a wrench ball head, and through the insertion groove on the transmission connector 4 that mates with the wrench ball head, the transmission connector 4 can drive the input end 12 or the output shaft 31 to rotate synchronously at a certain angle. Therefore, under the action of the transmission connector 4 of this utility model, the problem of misalignment between the input end 12 and the output shaft 31 can be overcome.

[0065] Furthermore, in this embodiment, when the second connecting part 311 and the second insertion slot 42 are not fastened with set screws, in order to make the connection between the input end 12 and the output shaft 31 more stable and the connection method simpler and more convenient, such as... Figures 4 to 6 As shown, a first reserved hole 421 can also be provided on the side wall of the second insertion groove 42. The first reserved hole 421 extends from the inner wall surface of the second insertion groove 42 along the radial direction of the transmission connector 4 to the outer surface of the transmission connector 4.

[0066] When the second connecting part 311 is inserted into the second insertion slot 42, the second connecting part 311 is connected by inserting a bolt into the first reserved hole 421 on the side wall of the second insertion slot 42 and pressing the bolt into the second connecting part 311. Alternatively, a second reserved hole 3111 that mates with the first reserved hole 421 can be provided on the second connecting part 311. After the bolt is inserted into the first reserved hole 421, it connects with the second reserved hole 3111, so that the transmission connecting part 4 and the output shaft 31 remain connected.

[0067] With the transmission connector 4 connected to the output shaft 31, the first connecting part 121 is inserted into the first insertion slot 41 to form a connection between the input end 12 and the output shaft 31. During the connection process, it is not necessary to position and fix the transmission connector 4 separately. Only the power source 3 needs to be moved to form a connection between the input end 12 and the output shaft 31. The connection method is very simple and quick.

[0068] Keeping the transmission connector 4 connected to the output shaft 31 can increase the stability of the connection between the input end 12 and the output shaft 31, and prevent the transmission connector 4 from shifting relative to the power source 3 during the synchronous rotation of the input end 12 driven by the power source 3, thus affecting the transmission connection of the power source 3 to drive the input end 12.

[0069] Furthermore, in this embodiment, to facilitate the insertion of the first connecting portion 121 into the first insertion slot 41 and the insertion of the second connecting portion 311 into the second insertion slot 42, as follows: Figures 4 to 6 As shown, a chamfer is provided at the connection between the end face and the peripheral face of the second connecting part 311. Furthermore, guide grooves are provided at the openings of the first insertion groove 41 and the second insertion groove 42.

[0070] It should be noted that, in this embodiment, to ensure that the outer casing 32 cannot rotate relative to the fixed end 11, the following method can be adopted: (e.g.) Figures 1 to 3 As shown, the transmission assembly 1 further includes a fixed end 11, on which a first limiting member 111 is connected. The power source 3 further includes a housing 32, on which a second limiting member 321 that cooperates with the first limiting member 111 is connected. The first limiting member 111 and the second limiting member 321 cooperate.

[0071] Furthermore, in this embodiment, in order to protect the power source 3 and also to limit the axial distance between the power source 3 and the transmission assembly 1, the power assembly also includes a protective cylinder 2, the power source 3 is placed inside the protective cylinder 2, and the protective cylinder 2 is connected to the fixed end 11.

[0072] In a second aspect of this embodiment, a photovoltaic tracking device includes: a photovoltaic panel and a power assembly as described above, wherein the power assembly is used to drive the photovoltaic panel to perform photovoltaic tracking.

[0073] The advantages of this utility model are: the connection between the input end 12 of the transmission component 1 and the output shaft 31 of the power source 3 is simpler and faster, the structure is simple, and the cost is reduced.

[0074] First, by using the transmission connector 4 proposed in this utility model, when connecting the input end 12 of the transmission component 1 to the output shaft 31 of the power source 3, the transmission connector 4 only needs to be coaxially connected to the first connecting part 121 through the first insertion slot 41, and the power source 3 is inserted into the second insertion slot 42 through the second connecting part 311. Alternatively, the transmission connector 4 can be coaxially connected to the second connecting part 311 through the second insertion slot 42, and the transmission component 1 can be inserted into the first insertion slot 41 through the first connecting part 121. That is, in use, after connecting the transmission connector 4 to either the transmission component 1 or the power source 3, the other can be directly inserted. Therefore, the connection between the input end 12 of the transmission component 1 and the output shaft 31 of the power source 3 is simpler and faster.

[0075] Meanwhile, the transmission connector 4 in the powertrain proposed by this utility model is an independent whole. It only needs to be machined at both ends to form insertion slots for cooperating with the first connecting part 121 and the second connecting part 311 respectively. This not only facilitates processing and helps to reduce processing costs, but also makes the structure of the transmission connector 4 simpler.

[0076] Secondly, by designing at least one of the first connecting part 121 and the second connecting part 311 as a wrench ball head, after cooperating with the corresponding insertion slot on the transmission connector 4, the problem of misalignment between the input end 12 of the transmission component 1 and the output shaft 31 of the power source 3 caused by machining errors or assembly errors is also eliminated.

[0077] Third, when only one of the first connecting part 121 and the second connecting part 311 is in the shape of a wrench ball, the other part can adopt a style that is easier to process and more cost-effective. For example, a keyway can be provided on the outer peripheral surface of the other part, or a through first reserved hole 421 can be provided on the transmission connecting part 4 that cooperates with the other part, thereby further saving processing costs.

[0078] Fourth, guide grooves can be provided at the openings of the first insertion groove 41 and the second insertion groove 42 on the transmission connector 4, or a chamfer can be provided at the connection between the end face and the circumference of the one that is not set in the shape of a wrench ball in the first connecting part 121 and the second connecting part 311. When assembling the power assembly proposed in this utility model, the guide grooves and / or chamfers enable the first connecting part 121 to be accurately and quickly inserted into the first insertion groove 41, and the second connecting part 311 to be accurately and quickly inserted into the second insertion groove 42, further ensuring that the connection between the input end 12 of the transmission component 1 and the output shaft 31 of the power source 3 is simpler and faster.
