[0005] This application provides a generator assembly, which includes a generator and a support base. The generator includes a base plate and a plurality of support feet extending outward from the base plate. The support base is used to support an external support member and provide support for the generator, such that the generator and the external support member are spaced apart. The support base has a support surface opposite to the base plate and a plurality of limiting grooves on the support surface. One support foot is used to insert and cooperate with one of the limiting grooves to achieve limiting installation. The support surface and the bottom surface of the generator are spaced apart to buffer the vibration of the generator relative to the support base.

[0006] According to an embodiment of this application, a generator assembly is provided, in which the generator is elevated by a support base, keeping its bottom away from external support components. This effectively avoids the risk of water ingress caused by rainwater accumulation and enhances the generator's adaptability to outdoor or rainy environments. The generator is positioned relative to the support base by inserting its support feet into the limiting grooves on the support base.

[0010] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0011] A generator is a power device that converts the chemical energy of fuel into electrical energy, widely used in engineering machinery, outdoor construction, and emergency power supply. A generator typically consists of multiple core components working together to form its overall functional framework. The engine, as the core component, is responsible for converting the chemical energy of fuel into mechanical energy, which is then used by the generator for energy conversion. Common engine types include diesel and gasoline engines. The generator further converts the mechanical energy output from the engine into usable electrical energy. Based on the specific output form, generators can be divided into alternating current (AC) generators and direct current (DC) generators, suitable for different power needs. To achieve precise control of the entire working process, the generator is also equipped with a control system. This control system handles start-stop operations, voltage regulation, and fault protection, such as overload protection and high-temperature alarms, ensuring stable operation even under complex working conditions. Simultaneously, the fuel system, through the cooperation of the fuel tank, filter, and fuel pump, ensures a continuous and stable fuel supply to the engine. To prevent the engine from overheating during prolonged operation, the engine also integrates a cooling and exhaust system to effectively dissipate heat and expel exhaust gases in a timely manner, thereby maintaining the normal operating condition of the entire system.

[0012] During operation, the engine rotates at high speed and undergoes combustion and explosion reactions, resulting in continuous and significant mechanical vibrations in the generator. In related technologies, generators are typically fixed to a support base using fasteners. This rigid connection method is not only cumbersome to assemble but may also exacerbate the vibration amplitude and even cause structural damage. This application provides a generator assembly that can improve the vibration problem during generator operation.

[0013] Please see Figures 1-2The generator assembly 1 includes a generator 10 and a support base 20. The generator 10 includes a base plate 11 and multiple support feet 12 that are located on the base plate 11 and extend outward. The support base 20 is used to support external support components. Depending on the application environment of the generator assembly 1, the external support components can be the ground, a platform, or an equipment frame, etc. The support base 20 is located below the generator and can provide support for the generator 10, so that the generator 10 is spaced apart from the external support components. In this way, by raising the generator 10 as a whole through the support base 20, the bottom of the generator is far away from the external support components, which can effectively avoid the risk of water ingress caused by rainwater accumulation and enhance the adaptability of the generator in outdoor or rainy environments.

[0014] Please see Figures 2-3 The support base 20 has a support surface 200, which is positioned opposite to the base plate 11. The support base 20 has multiple limiting grooves 21 on the support surface 200. Each support leg 12 is inserted into one limiting groove 21 for positioning. The support surface 200 is spaced apart from the bottom surface of the generator 10. This insertion fit effectively limits the circumferential positioning of the support legs 12, thereby suppressing generator 10 offset. It also helps reduce the contact area between the generator 10 and the support base 20, slowing the transmission of vibration energy and improving the vibration damping performance of the generator assembly 1. Furthermore, compared to traditional fastener connections, the insertion fit simplifies the installation process, improving assembly efficiency and convenience.

[0015] In some embodiments, at least some of the limiting grooves 21 are provided corresponding to the corner areas of the support surface 200, so that the distribution range of the multiple limiting grooves 21 is wider. The multiple limiting grooves 21 and the multiple support feet 12 can provide more stable support for the generator 10. At the same time, the structural rigidity of the corner area is better, which can more effectively bear the vibration load during the operation of the generator 10 and distribute and transmit the vibration load. The vibration stress generated by the operation of the generator is distributed and transmitted over a larger range, reducing local structural fatigue and wear, and enhancing the stability and durability of the entire support base 20.

[0016] Please see Figure 4In some embodiments, the support surface 200 has a first diagonal and a second diagonal arranged at an angle, wherein two corner regions 20a are spaced apart along the first diagonal and the other two corner regions 20a are spaced apart along the second diagonal. At least a portion of the plurality of limiting grooves 21 are first limiting grooves 211, and each corner region 20a is provided with at least one first limiting groove 211. In this way, the support base 20 can provide effective support for the generator 10 and help enhance the generator 10's resistance to displacement in the initial installation state. For example, the support surface 200 is generally rectangular, and the four corner regions 20a are located in the extension directions of the first and second diagonals, respectively. By symmetrically arranging the limiting grooves 21 along the two diagonals, a more balanced structural support pattern is formed, so that the vibration load of the generator 10 under stress is more evenly distributed to each corner region 20a of the support base 20, reducing the risk of structural deformation and loosening caused by vibration or off-center loading.

[0017] In actual manufacturing, technicians can arrange the positions of multiple support feet 12 according to the gravity distribution characteristics of the generator 10 itself, and accordingly set the spacing and distribution of multiple first limiting grooves 211 on the support base 20. For example, in the generator 10, the generator and engine are usually concentrated on the same side, which has a larger self-weight, so its corresponding support feet 12 are arranged more densely to enhance load-bearing capacity and vibration resistance; while the side without the generator and engine has a lighter overall load, and the corresponding support feet 12 can be arranged more sparsely. Based on this, the multiple first limiting grooves 211 are arranged accordingly to match the support limiting structure of the support base 20 with the center of gravity distribution of the generator, thereby improving the load-bearing balance capacity of the support base 20.

[0018] Optionally, at least one of the multiple limiting grooves 21 is a second limiting groove 212. The second limiting groove 212 is set in the middle area of ​​the support surface 200. The second limiting groove 212 is used to cooperate with the support foot 12 located in the middle of the base plate 11 of the generator 10 for auxiliary limiting. The combined arrangement of the first limiting groove 211 and the second limiting groove 212 can realize the joint constraint of the support foot 12 of the generator 10 in the corner and center areas, so that the transmission path of the vibration load on the support surface 200 is more uniform, thereby improving the stress coordination and buffer stability of the overall structure.

[0019] In this embodiment, the support base 20 includes a support plate 22 and a support body 23. The support body 23 is connected to the support plate 22. The support plate 22 has a support surface 200, and the support body 23 has a support bottom surface for bearing against an external support member. In actual use, the generator 10 rests against the support plate 22, and the support body 23 is installed on the external support member, so that the support base 20 is stably supported against the external support member.

[0020] In some embodiments, the support body 23 is integrally formed with the support plate 22, and the support body 23 is arranged circumferentially around the support plate 22. The outer periphery of the support body 23 forms a closed structure, resulting in better support stability. The surface of the support body 23 facing away from the support plate 22 is used to rest against external support members. It is understood that the integral formation of the support body 23 and the support plate 22 provides better overall structural rigidity of the support base 20, which helps to enhance the stability and reliability of the support base 20 under long-term operating conditions of the generator 10, while also simplifying the manufacturing and assembly process.

[0021] In other embodiments, please refer to Figures 5-8 The support plate 22 is movably installed on the support body 23 along the first direction X perpendicular to the support surface 200, thereby adjusting the distance between the support surface 200 and the support bottom surface. In other words, the support height of the support seat 20 is adjustable, so as to adapt to the height requirements of the generator 10 in different installation scenarios. For example, when used outdoors in rainy weather, the support surface 200 can be raised to a position to prevent the generator 10 from contacting water accumulation, thereby enhancing the safety and reliability of the generator assembly 1 in complex environments.

[0022] In some of these embodiments, such as Figure 5 and Figure 6 As shown, the support body 23 includes a support base wall 231 with a support bottom surface. The support body 23 also includes telescopic columns 233, which are connected to both the support base wall 231 and the support plate 22. The telescopic columns 233 are designed to be telescopic along a first direction X to adjust the distance between the support surface 200 and the support bottom surface. Thus, by providing the telescopic columns 233, the support plate 22 has a certain adjustment range in the first direction X.

[0023] In other embodiments, such as Figure 7 and Figure 8 As shown, the support body 23 includes a support base wall 231 with a support bottom surface. The support body 23 also includes a threaded rod 234 and a limiting nut 235. The support plate 22 has a threaded opening 220. The axial direction of the threaded rod 234 is parallel to the first direction X, with one end connected to the support base wall 231 and the other end passing through the threaded opening 220. The limiting nut 235 is located between the support base wall 231 and the support plate 22 and is sleeved on the threaded rod 234, contacting the support plate 22 to adjust the distance between the support surface 200 and the support bottom surface. In actual use, by rotating the limiting nut 235, it can move along the first direction X on the threaded rod 234, thereby causing the support plate 22, which is in contact with the limiting nut 235, to rise and fall relative to the support base wall 231 in the first direction X, providing good load-bearing capacity and adjustment stability.

[0024] Based on the support base 20 of the above embodiments, such as Figure 9As shown, along the first direction X perpendicular to the support surface 200, the dimension of the support base 20 is L, where L satisfies: 20cm ≤ L ≤ 80cm. By controlling the dimension L of the support base 20 to meet the above range, the center of gravity of the generator assembly 1 is placed at an appropriate height to ensure support stability, while also meeting the ground clearance requirements of the generator 10 in different application scenarios. If L < 20cm, the support base 20 is difficult to adapt to outdoor environments prone to water accumulation, and the base plate 11 of the generator 10 is too close to the ground, making it easy for water to enter or become contaminated; if L > 80cm, since the weight of the generator 10 is much greater than the weight of the support base 20, the center of gravity of the generator assembly 1 is too high, and the vibration of the generator 10 during operation can easily cause large-scale shaking, or even tipping over.

[0025] Please see Figures 10-12 The support foot 12 includes a support portion 121 and a first buffer member 122. The support portion 121 is located on the base plate 11 of the generator 10 and has a mounting groove 1210. Part of the first buffer member 122 is installed in the mounting groove 1210, and another part extends out of the mounting groove 1210. The part of the first buffer member 122 extending out of the mounting groove 1210 is used to insert into the limiting groove 21. The first buffer member 122 is made of an elastic material, such as rubber, giving it good elastic deformation capability. The first buffer member 122 can absorb or buffer part of the kinetic energy when the generator 10 vibrates during operation, reducing the transmission of vibration to the support base 20 and external support members. Generally, the support portion 121 is supported by a rigid material to ensure the structural load-bearing capacity and shape stability. The support portion 121 and the support base 20 are spaced apart to avoid direct contact between rigid components, reduce the vibration amplification effect caused by rigid collisions, and provide an effective structural transition and flexible protection for the entire limiting and buffering structure.

[0026] Please continue reading. Figure 12 The support foot 12 also includes a positioning member 123, a first locking member 124, and a second locking member 125. The first buffer member 122 has a central hole. The positioning member 123 extends radially to both sides of the central hole of the first buffer member 122. A portion of the positioning member 123 is located inside the first buffer member 122, and another portion is exposed inside the central hole. The portion of the positioning member 123 exposed inside the central hole has an installation opening. The first locking member 124 is installed inside the support part 121. The second locking member 125 is set corresponding to the central hole, and one end of the second locking member 125 abuts against the positioning member 123, while the other end passes through the installation opening of the positioning member 123 and is threadedly connected to the first locking member 124. The positioning member 123, the first locking member 124, and the second locking member 125 are made of rigid materials. In this way, a stable connection between the support part 121 and the first buffer member 122 is achieved through the positioning member 123, the first locking member 124, and the second locking member 125.

[0027] Optionally, the size of the portion of the first buffer member 122 extending out of the mounting groove is configured to be greater than the groove depth of the limiting groove 21, so that a portion of the first buffer member 122 is disposed between the mounting groove of the support portion 121 and the limiting groove 21, thereby achieving a spaced arrangement between the support portion 121 and the support base 20.

[0028] In some embodiments, the first buffer 122 has a plurality of spaced protrusions 1221 at one end facing the mounting groove, and the plurality of protrusions 1221 abut against the bottom wall of the limiting groove 21. If the end of the first buffer 122 facing the mounting groove is a planar structure, the first buffer 122 is prone to momentary separation or loosening relative to the limiting groove 21 due to the vibration of the oil machine 10. In this embodiment, the first buffer 122 has a plurality of protrusions 1221. When the oil machine 10 vibrates, the protrusions 1221 undergo elastic deformation, achieving elastic compression and elastic recovery within a certain range, buffering the vibration energy of the oil machine 10. Furthermore, the elastic recovery of the protrusions 1221 allows them to maintain contact with the bottom wall of the limiting groove 210, preventing the first buffer 122 from detaching from the limiting groove 21. Compared to setting the end of the first buffer 122 away from the support 121 as a planar structure, the plurality of protrusions 1221 provide a locally deformable elastic contact interface, giving the first buffer 122 greater deformation freedom and response space during vibration. This not only improves the flexibility of the buffer structure, but also helps maintain a stable contact area under vibration and impact from different directions, avoiding instantaneous detachment that could cause impact transmission, thereby enhancing the shock absorption effect and limiting reliability.

[0029] It should be noted that the adjacent boundaries of the corner area 20a of the support plate 22 are connected to the support body 23. The corner area 20a has higher local stiffness and stronger bending and torsional resistance. Therefore, when subjected to load or vibration, the structural deformation is relatively small, and it is less prone to local deformation or loosening. Thus, in this embodiment, an installation structure is provided for the corner area 20a of the support plate 22 to provide more reliable support. Specifically, the corner area 20a of the support surface 200 is provided with a clearance groove 20b, and the portion of the clearance groove 20b defined by the support base 20 is used for detachable installation on an external support member.

[0030] In some embodiments, such as Figure 13As shown, the support body 23 includes a support bottom wall 231 and a positioning side wall 232 located at the corner region 20a. The positioning side wall 232 is connected to both the support plate 22 and the support bottom wall 231, and the support bottom wall 231 is connected to the portion of the positioning side wall 232 away from the support plate 22. Thus, the support bottom wall 231 and the positioning side wall 232 together define a clearance groove 20b. The end of the support bottom wall 231 facing away from the support plate 22 is used to abut against an external support member. The external support member can provide additional constraints on the support bottom wall 231, suppressing the vibration and displacement of the support base 20. In addition, the clearance groove 20b is located adjacent to the first limiting groove 211, which helps to improve the limiting rigidity and installation stability of the support foot 12, and can also make fuller use of the structural constraint characteristics of the corner region 20a to reduce the dynamic response caused by resonance.

[0031] Optionally, the support base 20 is fixedly installed on the external support component. The bottom wall 231 of the support is provided with positioning holes, which are used to achieve a fixed connection between the support base 20 and the external support component through fasteners. For example, the positioning holes can be used with pre-embedded bolts to achieve a reliable connection with the concrete ground, or they can be directly fixed to grass, wooden boards, etc. through fastening structures such as nails, thereby forming a stable connection to adapt to the installation requirements of different usage scenarios.

[0032] Please see Figures 13-14 In other embodiments, the support base 20 further includes a second buffer 24, which enables non-fixed installation of the support base 20. The second buffer 24 is located on the side of the support body 23 facing the external support member, i.e., on the bottom wall 231 of the support. In this embodiment, the second buffer 24 is made of an elastic material, possessing good elasticity. When in contact with the external support member, the second buffer 24 not only absorbs some vibration energy but also effectively isolates the high-frequency vibrations of the generator 10 during operation through elastic deformation. In practical use, the surface of the second buffer 24 can be provided with stripes or anti-slip textures to increase the contact area between the second buffer 24 and the external support member, enhance friction, and suppress displacement of the support base 20 due to vibration of the generator 10.

[0033] Optionally, the support base wall 231 has a groove on the surface opposite to the support plate 22, and a portion of the second buffer member 24 is embedded in the groove. The connection between the second buffer member 24 and the groove includes at least one of adhesive bonding and interference fit, so as to form a stable connection structure between the second buffer member 24 and the support base wall 231, reducing the risk of the second buffer member 24 falling off or displacing under the vibration load generated by the operation of the oil machine 10.

[0034] In practical use, to prevent the generator from being stolen, users typically use chains to connect the generator 10 to fixed facilities. In this embodiment, the generator assembly 1 is designed accordingly. The base plate 11 of the generator 10 has a first locking hole 100 for threading the chain, while the support surface 200 of the support base 20 has a second locking hole 240. When the generator 10 is placed on the support base 20, the first locking hole 100 and the second locking hole 240 cooperate, allowing the chain to pass sequentially through the base plate 11 and the support base 20, forming a smooth locking path. This reliably connects the generator 10 to fixed facilities (such as ground stakes, iron railings, or building components), locking the generator 10 in a preset position. Thus, through the matching design of the generator 10 and the support base 20, the traditional use of anti-theft chains is retained, improving the overall locking stability and making the chain less susceptible to cutting or bypassing, thereby enhancing the anti-theft capability of the generator assembly 1 in outdoor or unattended scenarios.
