Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic power generation, and in particular to a telescopic frame supporting structure used for supporting a telescopic frame of a photovoltaic panel. Background Art

[0002] Photovoltaic power generation is a technology that uses the semiconductor photovoltaic effect to directly convert light energy into electrical energy. Photovoltaic power generation is clean and pollution-free and is widely used in many occasions. In the prior art, photovoltaic panels are fixedly installed, such as on roofs, car roofs, boat roofs, etc., and are converted into electrical energy through sunlight.

[0003] Therefore, the applicant has developed a vehicle-mounted photovoltaic device for use on the top of a car, with the announcement number CN220964712U. The device can be expanded or retracted by sliding a transverse telescopic frame and a longitudinal telescopic frame arranged on the main frame. When expanded, the photovoltaic panel generates electricity by the photoelectric effect. When not in use, the transverse telescopic frame and the longitudinal telescopic frame are retracted to form a retracted state. During use, since the length of the longitudinal telescopic frame is relatively large, when the transverse telescopic frame is expanded, the middle position of the transverse telescopic plate droops downward under the action of gravity, causing the middle position of the transverse telescopic plate to deform downward, thereby interfering with the frame of the main frame and failing to be smoothly expanded or retracted, seriously affecting the use of the product. At the same time, since the product is installed on the top of the car, the height dimension of the device installed on the top of the car is strictly limited in the national installation standard. Therefore, the height dimension of the device cannot be increased, that is, the spacing distance between the transverse telescopic plate and the main frame cannot be increased.

[0004] Therefore, there is an urgent need for a support structure to solve the above-mentioned technical problems. Utility Model Content

[0028] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with the embodiments and drawings, and the contents mentioned in the implementation modes are not intended to limit the present invention. The present invention is described in detail below in conjunction with the drawings.

[0029] The embodiment of the utility model provides a support structure for a telescopic frame 200, which is used to support the telescopic frame 200, so that the telescopic frame 200 maintains a horizontal state, does not bend downward under the action of gravity, and thus interferes with the main frame 100 to affect the extension or retraction of the telescopic frame 200, and can maintain a horizontal state under the action of the support structure after the telescopic frame 200 extends out of the main frame 100, and can have higher performance. In this embodiment, the support structure is used on a vehicle-mounted telescopic photovoltaic device, and can keep the photovoltaic panel in a horizontal state after the photovoltaic panel is unfolded, thereby improving the performance. At the same time, through the support structure, the transverse telescopic frame 200 or the longitudinal telescopic frame 300 of the photovoltaic device can be smoothly extended or retracted on the main frame 100 without increasing the height of the vehicle-mounted photovoltaic device. In the process of the telescopic action, there will be no mutual interference with the main frame 100, ensuring that the telescopic action of the telescopic frame 200 is smooth and reliable.

[0030] like Figure 1-4 As shown, a telescopic frame 200 support structure provided by an embodiment of the utility model includes a main frame 100, at least one telescopic frame 200, and a pull-out guide rail 101 for the telescopic frame 200 to be telescopically installed on the main frame 100, and also includes a support structure for supporting the middle position of the telescopic frame 200, the support structure includes a crossbeam 211 installed on the main frame 100, a connecting frame 213 for connecting the crossbeam 211 to the main frame 100, and a support beam 214, wherein the crossbeam 211 spans the main frame 100, and is parallel to the pull-out guide rail 101, and a slide groove 212 is provided along the length direction of the crossbeam 211;

[0031] The connecting frame 213 includes two connecting frames 213 respectively arranged at both ends of the beam 211, one end of the connecting frame 213 is fixedly connected to the beam 211, and the other end is fixedly connected to the main frame body 100; the supporting beam 214 is fixedly connected to the middle position of the telescopic frame 200 and is slidably connected in the slide groove 212.

[0032] The support beam 214 is fixedly installed in the middle position of the telescopic frame 200, thereby increasing the strength of the telescopic frame 200 and preventing the middle position of the telescopic frame 200 from collapsing downward under the action of gravity. When the telescopic frame 200 is extended or retracted on the main frame body 100 along the pull-out guide rail 101, it avoids interference with the main frame body 100, and the vehicle-mounted photovoltaic device can be smoothly unfolded or folded.

[0033] It is worth noting that, since the height of the items cannot exceed 30CM when adding items on the top of the motor vehicle, the overall height of the vehicle-mounted photovoltaic device cannot exceed 30CM. When the photovoltaic device generates electricity, a larger photovoltaic panel is usually set. During use, the photovoltaic panel is installed on the main frame 100 and the telescopic frame 200. After the telescopic frame 200 and the main frame 100 are unfolded, the photovoltaic effect of the larger photovoltaic panel is used to generate electricity. At this time, the main frame 100 and the telescopic frame 200 usually have a larger area size. Under the action of gravity, the telescopic frame 200 often sags in the middle, forming a U-shaped arc. When the telescopic frame 200 is extended or retracted, the telescopic frame 2 00, the lower end will rub against or interfere with the main frame 100, thereby preventing the telescopic frame 200 from being smoothly extended or retracted. At this time, the maximum height of the vehicle-mounted photovoltaic device is limited, and the above problem cannot be solved by increasing the distance between the main frame and the telescopic frame 200. Therefore, the support structure provided by the embodiment of the utility model can support the telescopic frame 200, improve the strength of the telescopic frame 200, and avoid sagging and deformation under the action of gravity due to the large size of the telescopic frame 200, thereby avoiding the lower side of the telescopic frame 200 from being placed on the main frame 100, reducing the mutual interference between the telescopic frame 200 and the main frame 100 when the telescopic frame 200 is extended and retracted, thereby affecting the smooth movement of the telescopic frame 200.

[0034] In this embodiment, the telescopic frame 200 includes an upper frame body 201 and a lower frame body 202 arranged side by side in an upper and lower direction, a cross beam 211 is arranged on the upper frame body 201 and the lower frame body 202, and slide grooves 212 are formed on the sides of the cross beam 211 facing the upper frame body 201 and the lower frame body 202 respectively; the support beam 214 includes two beams fixedly installed on the upper frame body 201 and the lower frame body 202, and are slidably connected in the slide grooves 212 respectively.

[0035] The telescopic frame 200 is arranged as two side by side in an upper and lower manner so as to increase the area of ​​the photovoltaic panel when unfolded. During use, the upper frame 201 and the lower frame 202 extend to the left and right directions on the main frame 100. At this time, the crossbeam 211 is arranged on the upper frame 201 and the lower frame 202, and slide grooves 212 are arranged on the upper and lower sides of the crossbeam 211. Correspondingly, the support beam 214 is provided with two slide grooves 212 respectively fixedly installed on the upper frame 201 and the lower frame 202 and both are slidably connected to the corresponding slide grooves. During the installation of the support beams 214, one support beam 214 is fixedly mounted on the lower surface of the upper frame 201 and is slidably connected in the slide groove 212 located on the upper side of the cross beam 211. When the upper frame 201 is extended or retracted from the main frame 100, the support beam 214 supports the middle of the upper frame 201 to prevent the upper frame 201 from sagging downward in the middle. Similarly, another support beam 214 is fixedly mounted on the upper surface of the lower frame 202 and is slidably connected in the slide groove 212 located on the lower side of the cross beam 211 to increase the strength of the lower frame 202 and prevent the lower frame 202 from sagging. Figure 1 As shown, two pull-out guide rails 101 are provided, which are respectively installed on the upper frame 201 and the lower frame 202 , so that the upper frame 201 and the lower frame 202 can move in a straight direction along the pull-out guide rail 101 .

[0036] In this embodiment, the main frame 100 includes an upper bracket 102 and a lower bracket 103 arranged up and down, and the telescopic frame 200 is telescopically arranged between the upper bracket 102 and the lower bracket 103; one end of one of the connecting frames 213 is fixedly connected to the end of the beam 211 corresponding to the upper frame 201, and the other end is fixedly connected to the lower bracket 103, and the support beam 214 installed on the upper frame 201 is slidably connected in the slide groove 212 located on the upper side of the beam 211; one end of the other connecting frame 213 is fixedly connected to the end of the beam 211 corresponding to the lower frame 202, and the other end is fixedly connected to the upper bracket 102, and the support beam 214 installed on the lower frame 202 is slidably connected in the slide groove 212 located on the lower side of the beam 211.

[0037] The crossbeam 211 is installed on the main frame 100 through two connecting frames 213. At this time, the upper side of one end of the crossbeam 211 and the upper bracket 102 are in an open structure, and the other end of the crossbeam 211 and the lower bracket 103 are in an open structure, so that the upper frame 201 and the lower frame 202 can be extended or retracted in two open spaces. At the same time, one end of the crossbeam 211 is pulled up at the upper end and the lower side of the other end of the crossbeam 211 is supported by the two connecting frames 213, so as to ensure that the crossbeam 211 has a strong supporting capacity in the vertical direction, thereby preventing the upper frame 201 and the lower frame 202 from falling and deforming downward.

[0038] In this embodiment, the support beam 214 is provided with a sliding portion 2141 and a connecting portion 2142 along the thickness direction, wherein the sliding portion 2141 is slidably connected to the slide slot 212 in a manner that matches the slide slot 212; the connecting portion 2142 has a width dimension greater than the width dimension of the sliding portion 2141, one side is formed with the sliding portion 2141, and the side away from the sliding portion 2141 is fixedly connected to the telescopic frame 200. At the same time, the cross section of the slide slot 212 is a "T"-shaped structure or a dovetail-shaped structure, and the sliding portion 2141 is provided as a "T"-shaped structure or a dovetail-shaped structure that matches the slide slot 212.

[0039] Setting the shape of the slide groove 212 and the sliding part 2141 to a "T"-shaped structure or a dovetail-shaped structure can ensure that the sliding part 2141 does not disengage from the slide groove 212 during the sliding process along the slide groove 212, thereby affecting the transmission performance. At the same time, through the setting of the "T"-shaped structure or the dovetail-shaped structure, the sliding part 2141 can have a certain load-bearing capacity, can provide a certain support for the upper frame 201 or the lower frame 202, and improve the strength of the upper frame 201 and the lower frame 202; designing the connecting part 2142 to have a width larger than the sliding part 2141 can increase the contact surface with the upper frame 201 or the lower frame 202, improve the supporting effect and load-bearing capacity of the support beam 214, and at the same time, the sliding part 2141 is enclosed in the slide groove 212 by the connecting part 2142, which can effectively create a sliding matching environment between the sliding part 2141 and the slide groove 212, thereby ensuring the transmission performance.

[0040] like Figure 5 As shown in the figure, a vehicle-mounted photovoltaic device using the support structure includes a main frame 100 and a longitudinal telescopic frame 300 that is telescopic along the length direction of the main frame 100. A telescopic frame 200 that is telescopic along the width direction is respectively arranged on the two longitudinal telescopic frames 300 and the main frame 100. When the vehicle-mounted photovoltaic device is opened for photovoltaic power generation, it appears as shown in FIG. Figure 5 In the state shown in FIG. 1 , when the telescopic frame 200 and the longitudinal telescopic frame 300 are retracted into the main frame body 100, the state is as shown in FIG. Figure 3The state shown. It can be understood that the main part of the longitudinal telescopic frame 300 constitutes the main frame 100 part of this embodiment, and the part that telescopes along the width direction of the longitudinal telescopic frame 300 constitutes the telescopic frame 200 in this embodiment. Similarly, the components in the middle of the vehicle-mounted photovoltaic device constitute the main frame 100 in this embodiment, and the parts that telescope along the width direction of the components in the middle of the photovoltaic device constitute the telescopic frame 200 in this embodiment. The support structure provided in this embodiment is arranged on at least one longitudinal telescopic frame 300, which is used to support the telescopic frame 200 located on the longitudinal telescopic frame 300, thereby improving the strength of the telescopic frame 200; similarly, the support structure provided in this embodiment is also arranged on the components in the middle of the photovoltaic device, which is used to support the telescopic frame 200 that telescopes along the width direction of the components in the middle of the photovoltaic device.

[0041] The support structure provided in this embodiment can support two telescopic frames 200 that are arranged side by side and extend in opposite directions, thereby improving the strength of the upper frame 201 and the lower frame 202, and can effectively prevent the upper frame 201 and the lower frame 202 from drooping downward in the middle due to the action of gravity. During the telescopic movement of the upper frame 201 and the lower frame 202, a safe distance is maintained from the main frame 100, and no mutual interference occurs, which can ensure that the upper frame 201 and the lower frame 202 can be smoothly extended or retracted.
