Description

TECHNICAL FIELD

[0001] The utility model relates to a transmission mechanism for support rotation driving device belongs to photovoltaic support technical field. BACKGROUND

[0002] As a clean energy, photovoltaic power generation is more and more widely concerned and applied, and the angle of photovoltaic module is adjusted intelligently to receive the direct sunlight of the sun to the maximum, and the power generation efficiency can be improved significantly. Therefore, the angle adjustment technology of photovoltaic module mounting support is paid more and more attention. Traditionally, many driving devices adopt worm gear driving equipment for angle adjustment, but this kind of way has low driving efficiency, installation and maintenance difficulties and other problems, especially when installing at high place, there are higher security risks and costs.

[0003] In order to solve the above problems, the recent improvement scheme turns to use the mode of steel wire rope combined with bearing. The specific method is that the steel wire rope is wound on the bearing, and the tension of the steel wire rope is controlled by the driving power source to control the rotation angle of the photovoltaic module mounting support. Although this method improves the installation convenience and driving effect to a certain extent, new problems come with it.

[0004] Long time use and continuous stress can cause the deformation of steel wire rope, and this deformation has a great influence in the transmission mechanism. Especially when two or more groups of steel wire ropes are used, due to the difference of installation environment, stress condition and other factors, the deformation difference of steel wire rope will be caused. This difference directly affects the stability of the bearing, thereby affecting the efficiency and safety of the whole photovoltaic module.

[0005] Therefore, it is the research purpose of the present application to design a transmission mechanism for support rotation, which can effectively improve the installation convenience and connection stability of the steel wire rope when cooperating with the bearing, and overcome the problem of not in place caused by the extension of the steel wire rope.

[0006] In view of the deficiencies of the prior art, the utility model aims at providing a transmission mechanism for support rotation driving device to solve the problems of the prior art.

[0007] In order to achieve the above purpose, the utility model is realized by the following technical scheme:

[0008] A transmission mechanism for support rotation driving device, comprising: a bearing rotatably arranged;

[0009] A second pulley assembly is fixedly arranged;

[0010] At least two groups of first flexible traction assemblies are arranged around the bearing, and at least two groups of second flexible traction assemblies are arranged outside the second pulley assembly.

[0011] a driving rod connecting one end of the first flexible traction assembly and one end of the second flexible traction assembly, and a rigid connecting assembly connecting the other end of the first flexible traction assembly and the other end of the second flexible traction assembly, the driving rod being driven by a corresponding driving mechanism.

[0012] As a further improvement, the first flexible traction assembly and the second flexible traction assembly are provided with two groups.

[0013] As a further improvement, a first pulley assembly is fixedly arranged near the bearing, and the first flexible traction assembly is abuttingly arranged inside the first pulley assembly.

[0014] As a further improvement, the first pulley assembly and the second pulley assembly each include a group of symmetrically arranged pulleys and a fixed frame fixedly connecting the two pulleys, the first flexible traction assembly is arranged between the two pulleys of the first pulley assembly, and the second flexible traction assembly is arranged outside the two pulleys of the second pulley assembly.

[0015] As a further improvement, the first flexible traction assembly includes a first steel wire rope that is arranged to wrap around the outer side of the bearing, the two ends of the first steel wire rope are bent inward, and the ends are fixedly connected to the rope body by a locking ring to form a first connecting ring and a second connecting ring, the first connecting ring is connected to the rigid connecting assembly, and the second connecting ring is connected to the driving mechanism.

[0016] As a further improvement, the second flexible traction assembly includes a second steel wire rope that is arranged to wrap around the outer side of the bearing, the two ends of the second steel wire rope are bent inward, and the ends are fixedly connected to the rope body by a locking ring to form a third connecting ring and a fourth connecting ring, the third connecting ring is connected to the rigid connecting assembly, and the fourth connecting ring is connected to the driving mechanism.

[0017] As a further improvement, the diameters of the first steel wire rope and the second steel wire rope are in the range of 6-14 mm.

[0018] As a further improvement, the rigid connecting assembly includes a first connecting rod connecting the first steel wire rope and the second steel wire rope, the two ends of the first connecting rod are bent inward to form a first hook body and a second hook body, the first hook body is connected to the first connecting ring, and the second hook body is connected to the third connecting ring.

[0019] As a further improvement, the driving rod includes a group of pull rods that are installed through the shell in parallel;

[0020] a set of connecting pieces symmetrically mounted on the ends of the pull rods, and a set of connecting rods symmetrically arranged on the connecting pieces, wherein the first connecting ring is connected to the connecting piece via the connecting rods, specifically, the connecting rods pass through the second connecting ring and then bend to form a fixing portion;

[0021] The fourth connecting ring is connected to the connecting piece through the connecting rod. Specifically, the connecting rod passes through the third connecting ring and then bends to form a fixing portion.

[0022] The beneficial effects of the utility model are:

[0023] This utility model reduces the length of each flexible traction component (wire rope) by dividing it into a first flexible traction component and a second flexible traction component. Rigid connecting components are introduced to compensate for deformation caused by stress. This design more effectively distributes the stress on each traction component, reducing deformation caused by uneven stress, thereby improving the stability and reliability of the entire drive device.

[0024] Since using a single set of flexible traction components may result in uneven stress and deformation, setting up two sets of flexible traction components allows each set of traction components to independently bear part of the load, further reducing the deformation and uneven stress of a single set of bearing components.

[0025] In the initial design, the traction assembly had limited fit with the load-bearing member. Therefore, a first pulley assembly was introduced, allowing the first flexible traction assembly to move inside the pulley, reducing friction and wear and improving fit with the load-bearing member. Furthermore, each pulley assembly is designed as a set of symmetrical pulleys, secured by a mounting bracket. This symmetrical configuration better balances forces and enhances traction stability.

[0026] The ends of wire ropes can be damaged due to uneven force or friction. By designing the ends of the wire ropes to bend inward and securing them with a locking ring, a stable connection is formed. This design enhances the structural stability and endurance of the ends, reducing damage caused by stress concentration.

[0027] By employing two sets of flexible components to shorten their operating length and combining them with a rigid connection component, deformation caused by stress during use is reduced, thereby improving the stability and reliability of the traction assembly. The rigid connection component connects the two sets of flexible traction components, forming a more stable structure during driving. The introduction of the rigid connection component effectively reduces the deformation differences between the flexible traction components, thereby improving the adjustment accuracy of the rotary drive device.

[0028] By optimizing the length of the flexible traction component and introducing a rigid connection component, the accuracy and reliability of the rotary drive device are improved, and the adjustment deviation problem caused by the deformation difference of the flexible traction component is reduced.

[0035] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the embodiments of the present application will be described clearly and completely below in conjunction with the drawings of the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only to represent selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0036] In the description of the present application, the terms "first", "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise specifically limited.

[0037] Because the driving force of the traditional angle adjusting device is uneven, the traditional single-sided driving mode is prone to efficiency loss and insufficient accuracy in force distribution, especially when the device structure is large. In severe weather such as strong wind and heavy snow, the impact of wind on the device is usually asymmetric, causing the device to tilt or shake during adjustment, affecting the accuracy of the photovoltaic panel adjustment and the effect of receiving sunlight. Therefore, a transmission mechanism for a support rotating driving device is designed to solve this problem.

[0038] Referring to Figures 1-4 A transmission mechanism for a support rotating driving device, comprising:

[0039] A bearing 1 arranged to rotate;

[0040] A second pulley assembly 5 arranged fixedly;

[0041] At least two groups of first flexible traction assemblies 2 arranged around the bearing 1, and at least two groups of second flexible traction assemblies 3 arranged around the outer side of the second pulley assembly 5;

[0042] A driving rod connected to one end of the first flexible traction assembly 2 and one end of the second flexible traction assembly 3 in the same group, and a rigid connection assembly 7 connected to the other end of the first flexible traction assembly 2 and the other end of the second flexible traction assembly 3, wherein the driving rod is driven to move by a corresponding driving mechanism 6.

[0043] The carrier 1 is a rotating component responsible for actually supporting and rotating the attached equipment (e.g. solar panels). It achieves rotation through interaction with the flexible traction assemblies.

[0044] Among them, two groups of flexible traction assemblies (usually steel wire ropes or similar materials), the first group of flexible traction assemblies 2 is arranged around the carrier 1, and the second group of flexible traction assemblies 3 is arranged around the fixed second pulley assembly 5. This configuration allows the carrier 1 to rotate under the action of traction force.

[0045] One end of each group of traction assemblies is connected to the drive mechanism 6 through a drive rod, and the other end is connected through a rigid connection assembly 7. The movement (e.g. extension or contraction) of the drive rod causes the length of the traction assembly to change, thereby causing the carrier 1 to rotate. The drive mechanism 6 controls the position and movement of the drive rod as needed to ensure accurate distribution of traction force and accurate angular adjustment of the carrier 1.

[0046] By using two groups of flexible assemblies to shorten the length of use, and cooperating with the rigid connection assembly 7 to reduce the deformation caused by stress during use, the stability and reliability of the traction assembly are improved. By using the rigid connection assembly 7 to connect the two groups of flexible traction assemblies, a more stable structure is formed when driving. The introduction of the rigid connection assembly 7 effectively reduces the deformation difference between the flexible traction assemblies, thereby improving the adjustment accuracy of the rotation driving device.

[0047] The first flexible traction assembly 2 and the second flexible traction assembly 3 are provided in two groups.

[0048] Through the arrangement of two groups of traction assemblies, the load and torque can be more evenly distributed, thereby increasing the stability of the entire system. This arrangement can reduce vibration and yaw caused by center of gravity deviation or uneven load, especially when the carrier 1 needs to be adjusted at a large angle or operates under dynamic conditions.

[0049] Using two groups of traction assemblies can significantly improve the carrying capacity of the entire driving device. Such a configuration allows the system to support heavier loads without causing excessive stretching or damage to the traction assemblies, which is particularly important for situations that require adjustment of large equipment such as large photovoltaic panels or other heavy mechanical equipment.

[0050] To increase the fit of the first flexible traction assembly 2 with the carrier 1, a first pulley assembly 4 is fixedly arranged near the carrier 1, and the first flexible traction assembly 2 is arranged inside the first pulley assembly 4.

[0051] The first pulley set and the second pulley set each include a set of symmetrically arranged pulleys 41 and a fixing frame 42 fixing the two pulleys 41, the first flexible traction assembly 2 passes between the two pulleys 41 of the first pulley set, and the second flexible traction assembly 3 surrounds the outside of the two pulleys 41 of the second pulley set.

[0052] The positioning member can be a wall, a fixing frame 42, a fixing column or other fixed support body.

[0053] When the device is used in harsh weather such as strong wind and heavy snow, the impact force from the outside is usually asymmetric, and through the design of the symmetrically arranged pulley set and flexible traction assembly, the device can better resist these asymmetric disturbances, ensuring the stability and safety of the system.

[0054] In order to ensure uniform force transmission during flexible traction, improve the stability and safety of the system, and ensure the reliability and efficiency of the traction device, the first flexible traction assembly 2 includes a first steel wire rope 21 that fits around the outer side surface of the bearing member 1, the two ends of the first steel wire rope 21 are bent inward, and the ends are fixed and locked on the rope body by a locking ring to form a first connecting ring 22 and a second connecting ring 23, the first connecting ring 22 is connected with the rigid connection assembly 7, and the second connecting ring 23 is connected with the drive machine 6.

[0055] The second flexible traction assembly 3 includes a second steel wire rope 31 that fits around the outer side surface of the bearing member 1, the two ends of the two second steel wire ropes 31 are bent inward, and the ends are fixed and locked on the rope body by a locking ring to form a third connecting ring 32 and a fourth connecting ring 33, the third connecting ring 32 is connected with the rigid connection assembly 7, and the fourth connecting ring 33 is connected with the drive machine 6.

[0056] The first and second flexible traction assemblies both use steel wire ropes to fit around the outer side surface of the bearing member 1, the main purpose is to ensure that the steel wire rope is tightly fitted with the bearing member 1 to form a stable traction structure. Through the design of surrounding, the traction force of the steel wire rope can act uniformly on the outer surface of the bearing member 1, not just concentrated in a certain point, avoiding damage or deformation caused by excessive local stress.

[0057] By bending and locking the two ends of the steel wire rope to form connecting rings (first, second, third and fourth connecting rings 33), the fixation of the two ends of the steel wire rope can be more reliable. The ring structure formed by bending and locking on the rope body itself makes the connection more stable, avoiding loosening or falling off of the steel wire rope due to uneven stress or long-term use. The strength and reliability of the connection are strengthened.

[0058] The first and third connecting rings 22 and 32 connect to the rigid connecting assembly 7, ensuring that the flexible traction assembly is effectively fixed to the rigid structural components of the system. The second and fourth connecting rings 23 and 33 connect to the drive motor 6, ensuring that the traction force can be accurately transmitted to the wire rope through the drive motor 6, thereby achieving control of the load-bearing component 1. This design aims to effectively combine the flexible and rigid components, maintaining the system's flexibility while enhancing structural stability.

[0059] The design of the steel wire rope encircling the support member 1 ensures that the traction force is evenly distributed across the surface of the support member 1. This even distribution of force avoids localized stress concentration and reduces the risk of deformation or damage to the support member 1 due to uneven force. Especially in large-scale equipment, the uniform traction force ensures stable and precise angle adjustment.

[0060] The connecting loop structure, formed by bending the ends of the wire rope and locking them with a locking ring, provides greater connection strength and stability. The reinforced fixing points prevent the wire rope from loosening or slipping during operation, maintaining the stability and safety of the traction system, especially when the system is in operation for long periods of time or subjected to strong external forces (such as wind and snow).

[0061] Because wire ropes are inherently strong and wear-resistant, securing them with locking rings enhances their durability and reduces failures due to fatigue or wear. Furthermore, locking the wire ropes to the rope body prevents end breakage, reduces maintenance costs, and improves system safety and long-term reliability.

[0062] The first and third connecting rings 22 and 32 are connected to the rigid connecting assembly 7, while the second and fourth connecting rings 23 and 33 are connected to the drive motor 6, ensuring efficient transmission between the flexible traction section and the rigid structure. This design allows the system to maintain flexibility during adjustment while ensuring precise transmission of traction force. The flexible steel wire rope reduces vibration or impact caused by the rigid structure during traction, while the rigid connecting section ensures stability and precision of adjustment.

[0063] By wrapping a flexible steel cable around the outer surface of the load-bearing element 1 and forming a connecting loop through bending and locking, the design achieves uniform force transmission, improving system stability and durability. The efficient transmission design between the flexible traction assembly, the rigid connection assembly 7, and the drive motor 6 ensures precise adjustment during operation, while also improving safety and long-term reliability. This well-balanced design is suitable for applications such as photovoltaic angle adjustment systems that require high precision and stability.

[0064] Since smaller diameter steel wires are more flexible than larger diameter steel wires, they can more easily adapt to the subtle adjustments of the equipment. Especially in photovoltaic panel angle adjustment systems, smaller steel wires can achieve faster response speed and higher precision, enabling the equipment to react more quickly to changes in the position of the sun, improving the energy capture efficiency of the overall photovoltaic system.

[0065] The existing single steel wire design, with a diameter of at least 20 mm after plastic coating, can withstand an 8-level wind and snow environment, and the diameter can reach 22 mm. In this scheme, the first steel wire rope 21 and the second steel wire rope 31 have a diameter range of 8-14 mm. After plastic coating, the diameter range is 10-16 mm. In this embodiment, the first steel wire rope 21 and the second steel wire rope 31 have a diameter of 10 mm, and after plastic coating, the diameter is 12 mm. The tensile strength is 1770 MPa, and it can withstand an 8-level wind and snow environment.

[0066] Choosing smaller diameter steel wires (such as 8-14 mm) can reduce the amount of material used, thereby reducing production and maintenance costs. Despite the reduction in the diameter of the steel wires, they still provide sufficient tensile strength (1770 MPa) and can withstand an 8-level wind and snow environment, which indicates that these smaller diameter steel wires have reached the strength requirements for practical applications.

[0067] Using thinner steel wires can significantly reduce the overall weight of the system, reducing structural load. This is particularly important for large photovoltaic systems, as lighter components mean that the entire system can use lighter supports and infrastructure without sacrificing stability and safety, reducing the need for structural materials and installation costs.

[0068] At the same time, the friction in the pulley 41 system is smaller, making the traction system more efficient. At the same time, the diameter after plastic coating is between 10-16 mm, and this layer of plastic coating can effectively reduce the direct contact between the steel wire rope and other metal parts, reducing friction and wear, and prolonging the service life of the steel wire rope and the pulley 41.

[0069] The diameter of the steel wire rope after plastic coating (10-16 mm) not only provides a physical protective layer to prevent the steel wire rope from being exposed to harsh environments and corroded and aged, but also increases the wear resistance of the steel wire rope. This is crucial for the durability of photovoltaic systems used outdoors for a long time, as it can reduce the risk of performance degradation and failure of the steel wire rope due to environmental factors.

[0070] The first and second steel wire ropes 31 have a diameter range of 8-14 mm (10-16 mm after plastic coating), which matches their tensile strength of 1770 MPa. This combination ensures that the diameter is reduced without sacrificing the tensile performance of the steel wire rope. This ensures that the equipment can still work normally in harsh environments such as wind and snow, and will not cause equipment failure due to the rupture or failure of the steel wire rope.

[0071] The steel wire rope with a diameter of 10 mm (12 mm after plastic coating) is of a moderate size, which reduces the material and weight while ensuring sufficient strength and wind and snow resistance. It can reduce the cost, improve the convenience of construction and installation, and make the steel wire rope more flexible, which can be used in various sizes and types of photovoltaic systems or similar equipment. The smaller diameter and high-strength design also make it suitable for modern equipment with lightweight design, which is beneficial to wide market application and equipment upgrading.

[0072] The steel wire rope with a smaller diameter (8-14 mm, 10-16 mm after plastic coating) ensures high tensile strength (1770 Mpa) and wind and snow resistance of grade 8, and optimizes the weight, cost and durability of the system. In this way, the design realizes lightweight, fast response, high durability and better environmental adaptability without sacrificing system performance and stability. The data shows that the safety, economy and efficiency are balanced, and it is suitable for various application scenarios and actual operating conditions.

[0073] In this scheme, the steel wire rope is made by winding multiple thin steel wires. The steel wire rope is usually made by winding several strands (usually 6 or 8 strands) around the core, and each strand contains multiple thin steel wires.

[0074] The rigid connection assembly 7 includes a first connecting rod 71 connecting the first steel wire rope and the second steel wire rope 31, and the two ends of the first connecting rod 71 are bent inward to form a first hook body 72 and a second hook body 73. The first hook body 72 is connected with the first connecting ring 22, and the second hook body 73 is connected with the third connecting ring 32.

[0075] The distance between the end of the first hook body 72 and the second hook body 73 and the main body is less than 1-1.5 mm of the diameter of the first steel wire rope 21 and the second steel wire rope 31. The diameter of the second connecting rod 68 is greater than the diameter interval of the first steel wire rope 21 and the second steel wire rope 31, which is 2-3 mm.

[0076] The distance between the end of the hook body and the main body is controlled to be less than 1-1.5 mm of the diameter of the steel wire rope, which is designed to ensure that the hook body can firmly grasp the steel wire rope, so as to avoid the steel wire rope from slipping or loosening during operation.

[0077] In order to realize the forward and reverse rotation of the motor 63 to realize the lifting of the pull rod 64, the driving mechanism 6 includes a mounting shell 61, an external threaded rod 62 rotatably installed in the mounting shell 61, and a motor 63 driving the external threaded rod 62 to rotate.

[0078] A set of pull rods 64 running parallel to the mounting housing 61 and an internally threaded locking disc 65 vertically mounted on the two pull rods 64 , wherein the internally threaded locking disc 65 is threadedly connected to the externally threaded rod 62 ;

[0079] The motor 63 cooperates with the external threaded rod 62 in the forward / reverse rotation to drive the internal threaded lock plate 65 to drive the pull rod 64 to move up / down.

[0080] The internal thread lock plate 65 is threadedly connected to the external thread rod 62, so that when the motor 63 drives the external thread rod 62 to rotate, the internal thread lock plate 65 will move up and down along the thread direction. By rotating the motor 63 in the forward or reverse direction, the internal thread lock plate 65 can be controlled to move up or down, thereby driving the pull rod 64 to move up or down.

[0081] The forward or reverse rotation of the motor 63 can be achieved by an accurate control system, which can provide smooth and accurate movement. Through the threaded structure, the rotational motion of the motor 63 is converted into linear motion, so that the height of the pull rod 64 can be easily adjusted.

[0082] Mounting housing 61 protects the internal externally threaded rod 62 and motor 63 from external environmental influences, particularly in outdoor or harsh operating environments, such as dust, moisture, wind, and snow, ensuring long-term, reliable operation of the internal mechanical structure. Mounting housing 61 also provides a stable structural foundation, ensuring smooth movement of the pull rod 64 and threaded rod, and preventing external factors from interfering with the internal motion mechanism.

[0083] The drive mechanism comprises a set of parallel tie rods 64 extending through the mounting housing 61, ensuring stability and synchronization during the lifting process. This design helps avoid imbalance issues associated with a single tie rod 64, ensuring system stability and preventing misalignment during the lifting process. An internally threaded locking disc 65 is mounted perpendicular to the tie rod 64. The locking disc and threaded rod cooperate to effectively transmit the rotational force of the motor 63 to the tie rod 64, enabling precise control of the tie rod 64.

[0084] By driving the rotation of the externally threaded rod 62 with motor 63, the system precisely controls the position of the tie rod 64. The threaded mechanical transmission method offers high precision and repeatability, making it suitable for applications requiring precise position adjustment, ensuring that the tie rod 64 remains stable at the desired height. The advantage of threaded transmission lies in its high torque transmission efficiency, enabling the lifting of large loads even with relatively low motor 63 power.

[0085] The pull rod 64 is driven by the motor 63 to realize the automatic operation of raising and lowering the pull rod 64 . The raising and lowering of the pull rod 64 can be easily realized by adjusting the rotation direction of the motor 63 .

[0086] The threaded transmission system has a natural self-locking function, especially when the pitch of the threaded rod is small. When the motor 63 stops running, the threaded structure can be self-locked to prevent the pull rod 64 from sliding or falling without external force. This self-locking function improves the safety of the system and avoids safety accidents caused by power failure or failure.

[0087] Due to the use of internal and external thread cooperation mechanical transmission, the system can withstand large load without deformation. Threaded connection has good performance in load bearing and stability, which makes this design suitable for occasions that need to bear heavy objects for a long time, ensuring stable lifting operation under load. The design of the pull rod 64 parallel through the mounting shell 61 further increases the stability of the entire system, avoiding the shaking or deviation of the pull rod 64 during lifting.

[0088] It should be emphasized that the connection parts of the mounting shell 61 are provided with sealing components, which can effectively protect the internal threaded rod and motor 63 from the influence of external environment such as dust, moisture, rain and snow. This can greatly prolong the service life of the system and reduce the failure or maintenance requirements caused by external environment.

[0089] The driving mechanism 6 further comprises a set of symmetrical connection pieces 67 installed at the end of the pull rod 64, and a set of symmetrical connection rods 68 arranged on the connection pieces 67, and the second connecting ring 23 is connected with the connection pieces 67 through the connection rods 68, specifically the connection rods 68 are bent to form fixed parts after penetrating the second connecting ring 23.

[0090] The fourth connecting ring 33 is connected with the connection pieces 67 through the connection rods 68, specifically the connection rods 68 are bent to form fixed parts after penetrating the fourth connecting ring 33.

[0091] Among them, the end of the connection rod 68 / pull rod 64 towards the connection piece 67 is provided with external threads, and the connection rod 68 and the end of the pull rod 64 are fixed by bolts.

[0092] Specifically, the connection piece 67 is divided into five equal parts by length, and the connection rod 68 and the pull rod 64 are respectively arranged on the second / third equal line from the center area to the equal line on both sides.

[0093] By dividing the connection piece 67 into five equal parts by length, and installing the connection rod 68 and the pull rod 64 on the second / third equal line respectively, a symmetrical layout can be achieved, making the system more uniform in load bearing. Uniformly distributed force can effectively avoid eccentric load or stress concentration, improving the stability of the entire structure.

[0094] And the installation of the connecting rod 68 and the pull rod 64 on the near-center bisector line helps to transfer the load to the central area of the connecting piece 67, making the overall structure more balanced in stress, reducing excessive stress concentration in the edge part, and avoiding fatigue or local deformation.

[0095] To prevent falling off and enhance fixation, the end of the connecting rod 68 is bent into a fixed hook design, which can provide additional physical restrictions to prevent the connecting rod 68 from sliding out of the connecting ring, improving the safety of the connection. This design not only increases the stability of the structure, but also enhances the shock resistance and impact resistance, avoiding the problem of loosening caused by vibration or external force.

[0096] The bending design also makes it easier to install and fix the connecting rod 68, simplifying the installation steps during assembly, and ensuring the tightness and reliability of the installation through the self-locking characteristics of the mechanical structure.

[0097] And setting external threads on the ends of the connecting rod 68 and the pull rod 64 and fixing them with bolts can achieve precise adjustment and strong fixation of the connecting rod 68 and the pull rod 64. This threaded structure can ensure that the connecting components fit tightly, avoiding loosening caused by external forces or vibration.

[0098] Threaded connections perform well in terms of tensile and shear resistance, especially for structures that need to withstand large tensile or shear forces. Through bolted fixation, the strength of the connection point can be further enhanced to prevent slipping or breaking under high stress conditions.

[0099] It is worth noting that no less than 2 bolts are provided at each link.

[0100] To ensure that the motor 63 can still work reliably in low-temperature and cold environments, a brushless DC motor is usually used. Brushless DC motors are highly efficient and have good energy consumption performance in cold environments, allowing them to work for a long time without excessive energy loss. Since there is no brush, the BLDC motor 63 can also avoid performance degradation due to component wear in low-temperature environments, while reducing maintenance requirements, especially for outdoor equipment driving systems in cold regions. Brushless DC motors can still maintain good starting performance at low temperatures and will not have difficulty starting due to excessively low temperatures. BLDC motors are suitable for precise control scenarios such as automation equipment, robots, and wind power equipment in cold regions.
