Description

Technical Field

[0001] The present invention relates to the technical field of generators, and particularly to a compact gasoline generator set. Background Art

[0002] A gasoline generator generally includes a power component and a power generation component. The power component is a key component that converts chemical energy into mechanical energy. It generates kinetic energy by burning fuel in a cylinder, drives a piston to reciprocate, and then drives a crank to rotate through a connecting rod to output power, and further drives a rotor to rotate. Through the principle of electromagnetic induction, mechanical energy is converted into electrical energy. Due to its advantages such as portability and emergency response, gasoline generators are widely used in various fields. For example, when camping in the wild, a gasoline generator can provide power for lighting, cooking utensils, etc. in a tent; at a construction site, it can provide power for various electric tools to avoid affecting the construction process; when natural disasters or accidents occur, a gasoline generator can also provide temporary power supply for the disaster area to ensure the smooth progress of rescue work.

[0003] The main body of the existing gasoline generator mostly adopts an open-frame structure and lacks the protection ability for core components. For example, when accidentally dropping or being impacted by an object in a strong wind environment, due to the lack of a buffer and energy absorption structure, the core components are easily directly impacted, resulting in damage to the main body of the gasoline generator; when used in a high-humidity environment, it is easy to cause short-circuit faults.

[0004] The information disclosed in the background art part of the present invention is only intended to deepen the understanding of the general background art of the present invention, and should not be regarded as an admission or any form of suggestion that this information constitutes the prior art known to those skilled in the art. Summary of the Invention

[0005] Based on this, it is necessary to provide a compact gasoline generator set in view of the problems existing in current gasoline generators.

[0006] The above object is achieved by the following technical solutions: A compact gasoline generator set includes a generator body and a protective frame arranged outside the generator body. A protective component is provided on the protective frame. One end of the protective component can move relative to the other end between a first position and a second position. When in the first position, the protective component is in a contracted state to open the protective frame; when in the second position, the protective component is in a stretched state to surround the protective frame.

[0007] Further, relative to the protective frame, one end of the protective component is a free end and the other end is a fixed end, and the free end can move relative to the fixed end between the first position and the second position.

[0008] Further, the protection component includes a plurality of blocking members and a plurality of elastic members. The adjacent blocking members are connected by the elastic members. The blocking member corresponding to the free end can move between the first position and the second position along a preset path, and drive the adjacent blocking members to move along the preset path through the elastic members.

[0009] Further, a control member is provided on the protection frame. The control member is located between the first position and the second position. The control member is used to prevent the blocking member from moving along the preset path, and the blocking member located between the control member and the second position exerts a surrounding effect on the protection frame.

[0010] Further, the number of the blocking members located between the control member and the second position is A, and A is a positive integer. The surrounding degree of the protection frame is positively correlated with the size of A.

[0011] Further, the blocking member has a cavity structure, and the inside of the cavity is in a negative pressure state. A plurality of side holes communicating with the cavity are formed on the blocking member.

[0012] Further, the side holes are formed on the side of the blocking member away from the generator body.

[0013] Further, a locking member is provided on the protection frame. The locking member is used to keep the blocking member corresponding to the free end at the second position.

[0014] Further, a sound-absorbing member is provided on the side of the blocking member close to the generator body.

[0015] Further, the protection frame includes an inner frame and an outer frame. The generator body is installed on the inner frame, and a plurality of buffer members are provided between the inner frame and the outer frame.

[0016] The beneficial effects of the present invention are as follows: The present invention provides a protection frame outside the generator body, which can buffer and absorb energy in case of accidental drop, and prevent the core components from being directly impacted and damaged; the two ends of the protection component are relatively close to make the protection component in a contracted state to open the protection frame, which is suitable for dry and windless environments; the two ends of the protection component are relatively far away to make the protection component in a stretched state to surround the protection frame, which is suitable for high-humidity environments, reduce short-circuit faults, and can also cooperate with the protection frame to prevent objects from hitting the generator body when used in a strong wind environment, thereby improving the protection ability of the generator body.

[0022] As Figures 1 to 16 shown, the embodiment of the present invention provides a compact gasoline generator set, including a generator body 100 and a protective frame 200 provided outside the generator body 100. A protective component 300 is provided on the protective frame 200. One end of the protective component 300 can move relative to the other end between a first position and a second position. When in the first position, the protective component 300 is in a contracted state to open the protective frame 200. When in the second position, the protective component 300 is in a stretched state to surround the protective frame 200.

[0023] A protective frame 200 is provided outside the generator body 100, which can buffer and absorb energy in case of accidental drops, avoiding direct impact on the core components and causing damage; the two ends of the protective component 300 are relatively close to each other, making the protective component 300 in a contracted state to open the protective frame 200, which is suitable for dry and windless environments; the two ends of the protective component 300 are relatively far away from each other to make the protective component 300 in a stretched state to surround the protective frame 200, which is suitable for high-humidity environments, reducing short-circuit faults. When used in windy environments, it can also cooperate with the protective frame 200 to prevent objects from hitting the generator body 100, thus improving the protection ability of the generator body 100.

[0024] Among them, the protective frame 200 can be a cylindrical frame structure or other shapes. Preferably, it is a rectangular parallelepiped or cube frame structure composed of a plurality of protective rods 206 perpendicular to each other. It has six open faces, which is more adaptable to the outer contour shape of the generator body 100, reducing the floor space and obtaining a more compact structure.

[0025] Among them, the protective component 300 is arranged on the protective rod 206. When the protective component 300 is in a contracted state, all the open faces of the protective frame 200 are opened. When the protective component 300 is stretched from this protective rod 206 to the opposite protective rod 206, this open face is surrounded. To simplify the structure, boxes 201 are arranged on the upper and lower open faces of the protective frame 200 to continuously surround the upper and lower open faces. At the same time, each box 201 has two chambers capable of storing two protective components 300. The openings of the two chambers face in opposite directions, so that the two protective components 300 can be stretched in opposite directions. Correspondingly, the stretching directions of the protective components 300 in the two boxes 201 are perpendicular to each other, so as to surround the four lateral open faces of the protective frame 200.

[0026] Among them, the first position is the position where one end of the protective component 300 is located when the protective component 300 is in a contracted state. The second position is the position where one end of the protective component 300 is located when the protective component 300 is in a stretched state.

[0027] Preferably, relative to the protective frame 200, one end of the protective component 300 is a free end and the other end is a fixed end. The free end can move between the first position and the second position relative to the fixed end.

[0028] One end of the protective component 300 is fixed and the other end is free. Therefore, only by controlling one end of the protective component 300 can it be contracted or stretched, which is convenient for operation.

[0029] Optionally, the middle of the protective component 300 is fixed to the protective frame 200, and the two ends of the protective component 300 are in a free state.

[0030] Preferably, the protection component 300 includes a plurality of blocking members 301 and a plurality of elastic members 302. The adjacent blocking members 301 are connected by the elastic members 302. The blocking member 301 corresponding to the free end can move between a first position and a second position along a preset path, and drive the adjacent blocking member 301 to move along the preset path through the elastic member 302.

[0031] The elastic member 302 can keep the adjacent blocking members 301 in a connected relationship, and the distance between the adjacent blocking members 301 can be elastically changed, so that the overall expansion and contraction of the protection component 300 has a certain elasticity.

[0032] Among them, referring to Figures 10 to 13 , the blocking member 301 is a rod, and a slider 303 is provided at the end of the blocking member 301. The elastic member 302 is arranged between the sliders 303 of two adjacent blocking members 301. When the protection component 300 is in a stretched state, there is a certain distance between two adjacent blocking members 301 to avoid affecting the heat dissipation of the generator body 100. A sliding groove 304 for the slider 303 to slide is opened on the vertically arranged protection rod 206. The sliding groove 304 communicates with the chamber in the box body 201 to jointly form a preset path, so that the blocking member 301 can move from the chamber in the box body 201 to the sliding groove 304, that is, move along the preset path.

[0033] Among them, referring to Figure 4 、 Figure 5 , the blocking member 301 corresponding to the fixed end can be directly fixed to the box body 201. The blocking member 301 corresponding to the free end can be manually pulled to move along the preset path until the enclosure protection frame 200 is surrounded. At this time, the elastic member 302 is a tension spring to pull the adjacent blocking member 301 to move along the preset path.

[0034] As a structural deformation, referring to Figure 15 、 Figure 16 , a conveyor belt 305 can also be provided in the chamber of the box body 201. A plurality of guide rollers are equidistantly arranged on the inner side of the conveyor belt 305, and one of the guide rollers is driven to rotate by a motor. When the conveyor belt 305 runs, it can drive the blocking member 301 to automatically move in the chamber of the box body 201 without manual operation. At this time, the elastic member 302 is a compression spring. Under the action of the elastic member 302, the blocking member 301 moves along the preset path until the enclosure protection frame 200 is surrounded.

[0035] Optionally, the protection component 300 can also adopt a structure similar to that of a shutter. At this time, each blocking member 301 is a strip-shaped blade, and a plurality of blades are arranged in parallel and the swinging angle of the blades is controlled by a pull rope to change the opening degree of the opening surface of the protection frame 200.

[0036] Optionally, the blocking member 301 may not move along the preset path. Instead, the blocking member 301 corresponding to the free end is pulled to stretch the entire protection assembly 300 to a certain length, and then the blocking member 301 corresponding to the free end is placed at the second position, similar to the process of using plastic wrap: pulling the end of the plastic wrap to pull out a section of the plastic wrap, and then pulling the end to cover the plastic wrap on the food.

[0037] Preferably, a control member 306 is provided on the protection frame 200. The control member 306 is located between the first position and the second position. The control member 306 is used to prevent the blocking member 301 from moving along the preset path. The blocking member 301 between the control member 306 and the second position exerts a surrounding effect on the protection frame 200.

[0038] Among them, referring to Figure 4 , Figure 8 , the control member 306 is slidably provided on the box body 201. A return spring 307 is provided between the control member 306 and the box body 201, so that the control member 306 has a tendency to slide into the box body 201. When the control member 306 slides into the box body 201, the control member 306 is located between two adjacent blocking members 301 to prevent the blocking member 301 from moving between the chamber in the box body 201 and the chute 304. The sliding of the control member 306 can be manually controlled, or an electric push rod or other structure can be additionally provided to drive the control member 306 to slide, and a corresponding controller is provided.

[0039] Optionally, a processor, as well as sensors such as a three-axis accelerometer or a gyroscope, are further provided on the protection frame 200. When the sensor detects an accidental drop, the processor first makes the control member 306 slide out of the chamber in the box body 201, that is, cancels the blocking effect on the blocking member 301. Then the processor controls the motor of the conveyor belt 305 to rotate, drives the conveyor belt 305 to run through the guide roller, so as to drive the blocking member 301 to move from the chamber in the box body 201 to the chute 304 until the protection frame 200 is surrounded.

[0040] Preferably, the number of the blocking members 301 between the control member 306 and the second position is A, and A is a positive integer. The surrounding degree of the protection frame 200 is positively correlated with the size of A.

[0041] The movement of the blocking member 301 along a preset path is blocked by the control member 306 to change the number of blocking members 301 that produce an enclosure effect on the protective frame 200. The larger the number of A, the smaller the interval between the blocking members 301 that produce the enclosure effect, and the greater the degree of enclosure of the protective frame 200, so as to freely change the degree of enclosure of the protective frame 200. For example, when A is 0, the protective frame 200 is in a fully open state, and the generator body 100 is applicable to a dry environment; when A is greater than 0 and less than the total number of all blocking members 301, the protective frame 200 is between the fully open state and the fully enclosed state, and the generator body 100 is applicable to a high-humidity environment, and at the same time, it cooperates with the protective frame 200 to prevent objects from hitting the generator body 100; when A is large enough but still less than the total number of all blocking members 301, the protective frame 200 is in a fully enclosed state, and the gasoline generator stops running to provide comprehensive protection for it.

[0042] When the protective frame 200 is in a fully open state, the opening surface of the protective frame 200 can dissipate heat from the generator body 100; when the protective frame 200 is between the fully open state and the fully enclosed state, there is a gap between adjacent blocking members 301, which can also dissipate heat from the generator body 100.

[0043] Among them, an induction module can be set to detect the environmental wind force and humidity in real time, so that the number of blocking members 301 that produce an enclosure effect can be adjusted in real time, that is, the gap between adjacent blocking members 301 can be adjusted.

[0044] Preferably, the blocking member 301 is a cavity structure, and the cavity is in a negative pressure state. A plurality of side holes 308 communicating with the cavity are opened on the blocking member 301.

[0045] The negative pressure environment in the cavity generates suction on the rainwater, preventing the rainwater from entering the protective frame 200 and falling on the generator body 100, reducing short-circuit faults. At the same time, the rainwater sucked into the cavity can also improve the heat dissipation effect of the generator body 100.

[0046] Among them, the protective rod 206 is also a cavity structure. A connecting hole 309 is provided on the side of the protective rod 206 close to the blocking member 301. An end hole 310 is jointly opened on the end of the blocking member 301 and the slider 303. Therefore, the cavity in the blocking member 301 is communicated with the cavity of the protective rod 206 through the end hole 310 and the connecting hole 309. In addition, a telescopic bent sealing film 311 is provided between the two sliders 303, and the width of the bent sealing film 311 remains unchanged during the telescopic process. When there is a gap between adjacent blocking members 301, the bent sealing film 311 can also block the connecting hole 309 to ensure the negative pressure environment.

[0047] Among them, a suction pump 315 is provided on the protective frame 200. The suction pump 315 is provided with a corresponding power supply and a controller to control the start and stop. The suction end of the suction pump 315 is communicated with the chamber in the box body 201, so as to generate negative pressure in the chamber in the box body 201, so that the cavities in the blocking member 301 and the protective rod 206 are both in a negative pressure state. In addition, the rainwater in the cavities of the blocking member 301 and the protective rod 206 is sucked in to effectively dissipate heat from the generator body 100. During the heat dissipation process, the rainwater gradually evaporates. After the rainwater evaporates completely during the long-term continuous operation of the generator body 100, water or a cold source can be additionally supplemented into the cavity through the suction pump 315 to ensure the heat dissipation of the generator body 100. Of course, a sensor can also be provided separately to detect the working temperature of the generator body 100 in real time to control whether to additionally supplement water or a cold source into the cavity through the suction pump 315.

[0048] Preferably, referring to Figure 10 , Figure 12 , Figure 13 , the side hole 308 is opened on the side of the blocking member 301 away from the generator body 100.

[0049] When the protective frame 200 is between the fully open state and the fully enclosed state, suction is generated on the rainwater through the side hole 308 on the outside to suck it into the cavity of the blocking member 301.

[0050] Optionally, the side hole 308 can also be located on the upper side of the blocking member 301.

[0051] Preferably, referring to Figure 4 , Figure 8 , a locking member 312 is provided on the protective frame 200. The locking member 312 is used to keep the corresponding blocking member 301 at the free end in the second position.

[0052] Among them, the structure of the locking member 312 can be: the locking member 312 is arranged on the corresponding blocking member 301 at the free end through a connecting plate 313. The locking member 312 can also slide along the sliding groove 304 on the protective rod 206. Pulling the locking member 312 can drive the corresponding blocking member 301 at the free end to move along a preset path. A locking structure is provided between the locking member 312 and the protective rod 206. The locking structure can be an existing magnetic attraction or buckle structure to lock the position of the locking member 312, so that the corresponding blocking member 301 at the free end is kept in the second position.

[0053] Preferably, referring to Figure 10 , a sound-absorbing member 314 is provided on the side of the blocking member 301 close to the generator body 100.

[0054] The sound-absorbing member 314 can be honeycomb-shaped, or a sound-absorbing coating can be applied to the side of the blocking member 301 close to the generator body 100, or the side of the blocking member 301 close to the generator body 100 is made of a sound-absorbing material to absorb the noise generated by the generator body 100.

[0055] Preferably, referring to Figure 1 , Figure 2 , the protective frame 200 includes an inner frame 202 and an outer frame 203. The generator body 100 is installed on the inner frame 202. A plurality of buffer members 204 are provided between the inner frame 202 and the outer frame 203 to enhance the strength and buffer energy absorption effect of the protective frame 200, and further prevent the core components from being directly impacted and damaged.

[0056] Among them, the outer frame 203 is composed of a plurality of protective rods 206. The buffer member 204 can be made of materials such as TPU, modified nylon or rubber. A support frame 205 is provided at the bottom of the outer frame 203 to keep a certain distance between the generator body 100 and the ground.

[0057] When the present invention is in use, a protective frame 200 composed of an outer frame 203, buffer members 204 and an inner frame 202 is provided outside the generator body 100, which can buffer and absorb energy in the event of an accidental drop, and prevent the core components from being directly impacted and damaged.

[0058] When used in a high-humidity environment, the two ends of the protective component 300 are relatively far away from each other so that the protective component 300 is in a stretched state to enclose the protective frame 200. Specifically, first slide the control member 306 out of the box body 201 to cancel the blocking effect on the blocking member 301, and then pull the locking member 312. It drives the blocking member 301 corresponding to the free end to move along a preset path through the connecting plate 313, and drives the adjacent blocking member 301 to move simultaneously through the elastic member 302 until the number of blocking members 301 is A moves from the chamber in the box body 201 to the sliding groove 304 to enclose the protective frame 200. The locking member 312 keeps the blocking member 301 corresponding to the free end in the second position, and then slides the control member 306 into the box body 201 to block the blocking member 301 at the corresponding position.

[0059] The larger the quantity of A is, the smaller the intervals of the blocking members 301 that produce the blocking effect are, and the greater the degree of blocking of the protection frame 200 is, so as to freely change the degree of blocking of the protection frame 200. When A is greater than 0 and less than the total number of all the blocking members 301, the protection frame 200 is between the fully open state and the fully blocked state. The negative pressure environment in the cavities of the blocking members 301 generates suction force on the rainwater, and the rainwater is sucked in through the side holes 308, preventing the rainwater from entering the protection frame 200 and falling on the generator body 100, reducing short-circuit faults. At the same time, the rainwater sucked into the cavities also improves the heat dissipation effect of the generator body 100. It is also applicable in a strong wind environment to cooperate with the protection frame 200 to prevent objects from hitting the generator body 100. When A is large enough but still less than the total number of all the blocking members 301, the protection frame 200 is in the fully blocked state, and the gasoline generator shuts down for comprehensive protection.

[0060] When used in a dry and windless environment, the two ends of the protection component 300 are relatively close to each other, making the protection component 300 in a contracted state to open the protection frame 200. Specifically, first, the control member 306 is slid out of the box body 201 to cancel the blocking effect on the blocking member 301, and then the locking member 312 is unlocked. The blocking member 301 moves reversely under the pulling force of the elastic member 302, that is, it moves from the chute 304 into the chamber in the box body 201. Then, the control member 306 is slid into the box body 201 to block the blocking member 301 corresponding to the free end. At this time, A is 0, and the protection frame 200 is in the fully open state.

[0061] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combinations of these technical features do not conflict, they should be considered as the scope described in this specification.

[0062] The above-described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it cannot be understood as a limitation on the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
