Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic components, and in particular to a foldable photovoltaic component frame. Background Art

[0002] Photovoltaic power generation is a technology that uses the photovoltaic effect of semiconductor interfaces to directly convert light energy into electrical energy. It is mainly composed of three parts: solar panels (modules), controllers and inverters. The main components are made of electronic components. Solar cells are packaged and protected after being connected in series to form large-area solar cell modules, which are then combined with power controllers and other components to form photovoltaic power generation devices.

[0003] With the popularity of cars, people have begun to choose self-driving tours. For self-driving tours with long distances, electricity consumption has become the biggest problem. The current electricity consumption solutions include generating electricity while the car is driving, and pasting solar panels on the roof to generate electricity. The amount of electricity generated by the car driving is too small; the solar panels pasted on the roof to generate electricity have a fixed area and cannot be retracted after pasting. The solar panels are easily damaged by wind and rain for a long time, resulting in reduced power generation efficiency. The existing photovoltaic modules are driven by motors and cylinders, which are not convenient to carry and install in the field. Summary of the invention

[0004] In order to solve the above-mentioned technical problems, a foldable photovoltaic module frame is provided.

[0008] Furthermore, a second clamping block is installed at intervals on the rack on the side of the fixed block, and the second clamping block is provided with a second card interface in the same direction as the first clamping block. The second card interfaces on the two sets of mounting and adjusting components are used to clamp the support rod at the bottom of the car luggage rack.

[0009] Furthermore, the second clamping block is installed in a staggered manner on the racks on both sides of the transmission gear.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Embodiment 1 of the present invention, as Figure 1As shown, the mounting base 1 includes a rectangular frame 11, a mounting plate 2 is fixed at the bottom center of the rectangular frame 11, a gear transmission mechanism 3 is arranged below the mounting plate 2, the gear transmission mechanism 3 includes a rotating shaft 31 arranged at the bottom center of the mounting plate 2, a worm wheel 32 and a transmission gear 33 are arranged on the rotating shaft 31 from top to bottom, a worm 34 is meshed and installed on the side of the worm wheel 32, racks 35 are meshed and installed on the left and right sides of the transmission gear 3, and an installation adjustment component 4 is arranged on the rack 35. At least three groups of photovoltaic frames 5 are arranged on the top of the rectangular frame 11, and the tops of two adjacent photovoltaic frames 5 are connected by a connecting rod 6. The end of the worm is a square block structure for installing an external rotating tool. The worm is rotated by the external tool to drive the gear transmission component to rotate, so that the installation adjustment component on the rack moves in the opposite direction until it is clamped from the inside to the outside to the luggage rack support rod on the top of the car, so as to ensure the stability of the overall structure. When the photovoltaic frame is in use, the connecting rod installed can achieve angle adjustment within 90° in the field. When not in use, the connecting rod is removed and folded for installation, so as to reduce the occupied space and avoid long-term exposure to the outdoors to affect the service life.

[0025] A guide rail 21 is installed at the corresponding position directly above the rack 35 at the bottom of the mounting plate 2 to provide positioning and guiding function for the rack. The slider on the guide rail 21 is fixedly connected to the rack 35, and the transmission gear 33 drives the racks 35 on both sides to make linear motion in opposite directions along the guide rail 1.

[0026] The installation and adjustment components 4 are provided with two groups and are installed in reverse. The installation and adjustment components 4 include a fixed block 1 arranged at the end of the rack 35 away from the side of the transmission gear 33. A limiting groove arranged in the same direction as the worm 34 is provided at the bottom of the fixed block 41. A first clamping block 42 is provided at one end of the limiting groove close to the outer side of the installation base 1. An adjustment rod extends from the side of the first clamping block 42 close to the limiting groove. The adjustment rod is movably arranged in the limiting groove and is fastened and limited by a locking bolt on the fixed block 41. An arc-shaped first clamping interface 421 is provided on the side of the first clamping block 42 away from the fixed block 41. The first clamping interface 421 is used to clamp the support rod on the side of the automobile luggage rack.

[0027] A second clamping block 43 is installed on the rack 35 on the side of the fixing block 41 at intervals, and a second clamping interface 431 is provided on the second clamping block 43 in the same direction as the first clamping block 42. The second clamping interface 431 on the two sets of mounting and adjusting components 4 is used to clamp the support rod at the bottom of the car luggage rack. Figure 6 As shown, the installation positions of the second clamping blocks 43 on the racks 35 on both sides of the transmission gear 33 are staggered. When the two sets of racks move in different directions, the second clamping interfaces of the two sets of second clamping blocks at corresponding positions move toward each other until they are clamped and fixed on the support rod at the bottom of the car luggage rack. The number of second clamping blocks can be adaptively adjusted according to the luggage rack structure.

[0028] like Figure 8As shown, the photovoltaic frame 5 includes a frame body 51, a positioning groove 52 for installing a photovoltaic component is opened on the front side of the frame body 51, a placement groove 53 is opened on the side of the frame body 51 away from the positioning groove 52, a buffer layer is arranged between the placement groove 53 and the frame body 51, a rotating section 54 is symmetrically arranged on the outer side of the frame body 51, and a connecting section 55 with a diameter smaller than the rotating section 54 is arranged between the rotating section 54 and the frame body 51.

[0029] Two support plates are arranged between the rectangular frame 11 and the mounting plate 2, and an adjusting sliding block 12 located inside the rectangular frame 11 is installed on the top of the support plate. A first slide groove 121 with a height greater than the diameter of the rotating section 54 is opened inside the adjusting sliding block 12, and a second slide groove 122 with a height greater than the connecting section 55 is opened on the end surface inside the adjusting sliding block 12. Positioning holes 13 corresponding to the number of the photovoltaic frame 5 are opened on the inner end surface of the adjusting sliding block 12, and the diameter of the positioning holes 13 matches the diameter of the rotating section on the frame body 51, such as Figure 7 As shown, the positioning hole is installed eccentrically with respect to the horizontal axis of the adjusting sliding block. When the rotating section of the photovoltaic frame is at the positioning hole, the connecting section at the bottom is not on the same horizontal line as the second slide groove and cannot move left and right. Therefore, this state is used to adjust the angle of the photovoltaic frame after the connecting rod is installed on the top of the photovoltaic frame. When the user removes the connecting rod, lift the right side of the photovoltaic frame upward so that the connecting section at the bottom is in the second slide groove, which can achieve left and right movement for folding the photovoltaic frame. The first slide groove 121 and the second slide groove 122 between the two adjacent groups of positioning holes 13 are in a blocking state to avoid collision between the photovoltaic components on the right and the left during the folding process.

[0030] Embodiment 2 of the present invention, as Figure 2 As shown, the photovoltaic frame is in the folded state. After removing the connecting rods one by one, lift the photovoltaic frame on the right side upwards in turn, so that the connecting section moves to the left in the second sliding grooves on both sides until it is engaged with the placement groove of the photovoltaic frame adjacent to the left. In order to ensure a smooth engagement process, the width of the photovoltaic frame decreases from left to right, and accordingly, the length of the connecting section increases in turn to ensure the connection of the connecting rod.

[0031] Several points that need to be explained are: First, in the description of the present application, it should be noted that, unless otherwise specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, and can be mechanical or electrical connections, or internal connectivity between two elements, or direct connections. "Up", "down", "left", "right", etc. are only used to indicate relative position relationships. When the absolute position of the object being described changes, the relative position relationship may change; secondly, in this article, relational terms such as first and second, etc. are only used to distinguish one entity from another, and do not necessarily require or imply that there is any such actual relationship or order between these entities.

[0032] The above examples are merely illustrative of the present invention and do not constitute a limitation on the protection scope of the present invention. All designs that are the same or similar to the present invention belong to the protection scope of the present invention.
