Description

Technical Field

[0001] This utility model relates to a high-efficiency coating, masking, and flipping device for battery trays. Background Technology

[0002] Battery trays are an important component of the electric power system in new energy vehicles and are crucial for ensuring the safety of the battery system. Therefore, battery trays need to have a certain load-bearing capacity; hence, they typically have a certain weight, usually below 100 kg.

[0003] To prevent leakage from the power battery pack from endangering vehicle occupants, the inner cavity of the battery tray needs to be coated with an insulating layer during production. Even if the power battery leaks or breaks, the battery tray will still maintain insulation. The battery tray insulation layer is applied locally; some mounting surfaces and side beams do not require an insulating coating, and currently, localized masking with high-temperature masking film is mostly used. During the masking process, specific areas on the top and bottom of the battery tray need to be masked. However, when the battery tray weighs over 25kg, flipping it typically requires at least two workers to work together. Therefore, to address the shortcomings of existing technology, a high-efficiency coating, masking, and flipping device for battery trays has been developed. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a high-efficiency coating, masking, and flipping device for battery trays.

[0005] In order to achieve the above-mentioned objectives of this utility model, the following technical solution is adopted:

[0006] A high-efficiency coating masking and flipping device for battery trays includes a support frame; a sliding mechanism; a foldable frame including a first frame and a second frame, the first frame being hinged to one end of the support frame, the second frame being mounted on the sliding mechanism, the sliding mechanism being hinged to the other end of the support frame, the first frame being hinged to the second frame; and a telescopic drive component, the telescopic drive component being inclined, one end being hinged to a bottom support seat, and the other end being provided with a piston, the piston being hinged to the first frame.

[0007] Furthermore, the battery tray high-efficiency coating masking and flipping device of this utility model also includes a first hinge component, and the first frame and the support frame are connected by the first hinge component.

[0008] Furthermore, the first hinge component includes a first shaft and a first hinge support, with the first hinge support sleeved at both ends of the first shaft; the first hinge support includes a longitudinal seat, a first U-shaped seat and a rotating sleeve, with one end of the longitudinal seat connected to the support frame and the other end connected to the first U-shaped seat, the side of the first U-shaped seat having a through hole, and the first shaft being sleeved through the through hole, and the rotating sleeve being sleeved on the first shaft.

[0009] Furthermore, the battery tray high-efficiency coating masking and flipping device of this utility model also includes a second hinge component, the first frame and the second frame are hinged together by the second hinge component; the second hinge component includes a second U-shaped seat, a third U-shaped seat and a second shaft, the second U-shaped seat is installed on the first frame, the third U-shaped seat is installed on the second frame, the second U-shaped seat and the third U-shaped seat are staggered and inserted, and the second shaft passes through the second U-shaped seat and the third U-shaped seat from the side.

[0010] Furthermore, the battery tray high-efficiency coating masking and flipping device of this utility model also includes a third hinge component, and the sliding mechanism is connected to the support frame through the third hinge component.

[0011] Furthermore, the third hinge component includes a vertical seat, which is erected; a fourth U-shaped seat, which is installed on the vertical seat; a second short section, one end of which is placed inside the fourth U-shaped seat and the other end of which extends out and connects to the sliding mechanism; and a third shaft, which passes through the fourth U-shaped seat and the second short section.

[0012] Furthermore, the sliding mechanism includes a base rod; a slide rail fixedly mounted on the bottom surface of the base rod; at least one slider slidably mounted on the slide rail; and a support plate, one side of which is connected to at least one slider and the other side of which is connected to a third hinge.

[0013] Furthermore, the support frame includes a first reinforcing rod, a second reinforcing rod, and two uprights. The two uprights are arranged in parallel with a gap between them, with one end connected by the first reinforcing rod and the other end connected by the second reinforcing rod. The first reinforcing rod is placed at the bottom of the two uprights, and the second reinforcing rod is installed at the top of the two uprights with a gap between them.

[0014] Furthermore, the support frame includes legs and longitudinal rods. Two legs are erected and arranged in parallel with intervals and connected by the longitudinal rods. Reinforcing ribs are installed between the longitudinal rods and the legs.

[0015] Furthermore, it also includes a fifth U-shaped seat, a rotating shaft, and a second support. The fifth U-shaped seat is connected to the piston and fitted onto the second support.

[0016] The present invention represents a significant advancement over the prior art:

[0017] This invention allows a single worker to flip a battery tray. Specifically, the battery tray to be flipped is placed on either the first or second frame. A telescopic drive retracts the piston, causing both the first and second frames to swing downwards. Simultaneously, the battery tray tilts downwards, forming a V-shape with the first and second frames. When the first and second frames reach the desired tilt angle, the telescopic drive stops retracting the piston. The worker then pushes the top of the battery tray, causing it to swing from one frame to the other. The telescopic drive then drives the first frame upwards, simultaneously causing the second frame to swing upwards as well. The second frame can slide upwards using a sliding mechanism. When the first and second frames are horizontally aligned, the telescopic drive stops driving the piston, which then supports the first frame, maintaining a supporting force and thus flipping the battery tray.

[0027] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions of this utility model will be clearly and completely described below in conjunction with the accompanying drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments in this application. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this application.

[0028] Example 1:

[0029] like Figure 1-5 As shown, a high-efficiency coating masking and flipping device for battery trays includes a support frame 7, a sliding mechanism 12, a foldable frame, and a telescopic drive component 5. The foldable frame includes a first frame 8 and a second frame 11. The first frame 8 is hinged to one end of the support frame 7. The second frame 11 is mounted on the sliding mechanism 12, which is hinged to the other end of the support frame 7. The first frame 8 and the second frame 11 are also hinged together. The telescopic drive component 5 is inclined, with one end hinged to a bottom support base and the other end equipped with a piston 51, which is hinged to the first frame 8.

[0030] The first frame 8 is hinged to the support frame 7, allowing the first frame 8 to swing relative to the support frame 7.

[0031] The second frame 11 is slidably connected to the sliding mechanism 12, and the sliding mechanism 12 is hinged to the support frame. The second frame 11 can swing relative to the support frame through the sliding mechanism, and can also slide through the sliding mechanism.

[0032] The telescopic drive component 5 is tilted, which makes it easier for the telescopic drive component to drive the piston to swing the first frame.

[0033] In some alternative embodiments, a hinged connection structure is provided between the first frame and the support frame. For example... Figure 1-3 As shown, a first hinge component 9 is added, and the first frame 8 and the support frame 7 are connected through the first hinge component 9.

[0034] Understandably, the first frame 8 can swing relative to the support frame via the first hinge 9.

[0035] In some alternative embodiments, a structure for the first hinge element is provided, such as... Figure 2 As shown, the first hinge component 9 includes a first shaft 95 and a first hinge support. Both ends of the first shaft 95 are fitted with the first hinge support. The first hinge support includes a longitudinal seat 91, a first U-shaped seat 92, and a rotating sleeve 94. One end of the longitudinal seat 91 is connected to the support frame 7, and the other end is connected to the first U-shaped seat 92. The side of the first U-shaped seat 92 has a through hole 100, through which it is fitted onto the first shaft 95. The rotating sleeve 94 is fitted onto the first shaft 95. The rotating sleeve 94 is used to connect to the first frame 8.

[0036] The longitudinal seat 91 is fixedly installed on the support frame and is arranged longitudinally, parallel to the length direction of the support frame. The first U-shaped seat 92 is fixedly connected to the longitudinal seat 91.

[0037] The first shaft 95 passes through the rotating sleeve 94 and the first U-shaped seat 92 passes through the through hole 100. The rotating sleeve can rotate relative to the first shaft.

[0038] Furthermore, this embodiment provides a connection structure between the rotating sleeve and the first frame 8, by adding a first short section 93, and the rotating sleeve 94 and the first frame 8 are connected by the first short section 93.

[0039] To prevent the first frame from moving axially along the first shaft 95, during installation, the rotating sleeve 94 and the first U-shaped seat 92 can be fitted together on the first shaft 95, and the first U-shaped seat 92 can block the movement of the rotating sleeve 94. Understandably, lubricating oil can be applied to the contact surface between the rotating sleeve and the first U-shaped seat to reduce rotational wear between the rotating sleeve and the first U-shaped seat.

[0040] Specifically, on the two first hinge supports, the two rotating sleeves 94 are installed at different positions relative to the first U-shaped seat. For example, the rotating sleeve on one of the first hinge supports is installed against the rear end face of the first U-shaped seat (which can be...). Figure 2For visual reference (and similarly below), the rotating sleeve on the other first hinge support is mounted against the front end face of the first U-shaped seat. Alternatively, the rotating sleeve on one first hinge support is mounted against the front end face of the first U-shaped seat, and the rotating sleeve on the other first hinge support is mounted against the rear end face of the first U-shaped seat. With the two rotating sleeves mounted on opposite sides, the first U-shaped seat can prevent the rotating sleeves from sliding axially along the first axis, thereby preventing the first frame from moving.

[0041] In some alternative embodiments, a hinged connection structure is provided between the first frame and the second frame, with an additional second hinge element 10 installed. The first frame 8 and the second frame 11 are hinged together via the second hinge element 10.

[0042] The second hinge component 10 includes a second U-shaped seat 101, a third U-shaped seat 102, and a second shaft 103. The second U-shaped seat 101 is mounted on the first frame 8, and the third U-shaped seat 102 is mounted on the second frame 11. The second U-shaped seat 101 and the third U-shaped seat 102 are interlocked and inserted. The second shaft 103 passes through the second U-shaped seat 101 and the third U-shaped seat 102 from the side.

[0043] like Figure 5 As shown, both the second U-shaped seat 101 and the third U-shaped seat 102 are provided with U-shaped grooves 200 and through holes 100 on their sides. The second U-shaped seat 101 and the third U-shaped seat 102 are sleeved on the second shaft 103 through the through holes. The second U-shaped seat 101 and the third U-shaped seat 102 can swing relative to each other through the second shaft 103.

[0044] Understandably, the second U-shaped seat 101 and the third U-shaped seat 102 are interlocked by the U-shaped groove 200. One side of the U-shaped groove on the second U-shaped seat 101 is inserted into the U-shaped groove of the third U-shaped seat 102, thus achieving the interlocked connection between the second U-shaped seat 101 and the third U-shaped seat 102.

[0045] In some alternative embodiments, a hinged connection structure is provided between the sliding mechanism and the support frame, with an additional third hinge element 13 installed. The sliding mechanism 12 is connected to the support frame 7 via the third hinge element 13. The sliding mechanism 12 can swing relative to the support frame by means of the third hinge element 13.

[0046] One structure for the third hinge element is given. For example... Figure 2 As shown, the third hinge component 13 includes a vertical seat 134, a fourth U-shaped seat 133, a second short section 131, and a third shaft 132. The vertical seat 134 is erected. The fourth U-shaped seat 133 is mounted on the vertical seat 134. One end of the second short section 131 is placed inside the fourth U-shaped seat 133, and the other end extends out and connects to the sliding mechanism. The third shaft 132 passes through the fourth U-shaped seat 133 and the second short section 133.

[0047] like Figure 5As shown, the fourth U-shaped seat 133 is provided with a U-shaped groove 200 and a through hole 100 on the side.

[0048] To facilitate the passage of the third shaft through the second short section 133, the second short section 133 is provided with a through hole (not shown in the figure) for the third shaft 132 to pass through.

[0049] like Figure 2 , 3 As shown, one end of the second short section 133 is placed in the U-shaped groove of the fourth U-shaped seat 133, and this end is provided with a through hole for the third shaft 132 to pass through. The third shaft 132 passes through the fourth U-shaped seat and the second short section 133. It can be understood that when the second short section is placed in the U-shaped seat, the U-shaped seat can prevent the second short section from moving axially along the third shaft, thereby preventing the sliding mechanism from moving axially along the third shaft, and thus preventing the second frame from moving laterally.

[0050] The second short section 133 can swing relative to the fourth U-shaped seat through the U-shaped groove of the fourth U-shaped seat 133.

[0051] In some alternative embodiments, one structure of the sliding mechanism is provided. For example... Figure 2 As shown, the sliding mechanism includes a base rod 121, a slide rail 122, at least one slider 123, and a support plate 124. The slide rail 122 is fixedly mounted on the bottom surface of the base rod 121. At least one slider 123 is slidably mounted on the slide rail 122. One side of the support plate 124 is connected to at least one slider 123, and the other side is connected to a third hinge member 13.

[0052] The number of sliders 1, 2, or 3 can be installed.

[0053] like Figure 2 As shown, the slide rail and slider are connected by an embedded sliding connection. Slider 123 is partially fitted onto the slide rail. This prevents the slider from detaching from the slide rail when the second frame swings.

[0054] When the second frame 11 swings, the second frame 11 can slide relative to the slider with the help of the slide rail, so that the second frame can slide while swinging.

[0055] In some alternative embodiments, a structure of the support frame is provided. The support frame 7 includes a first reinforcing rod 6, a second reinforcing rod 14, and two uprights. The two uprights are arranged in parallel with a gap between them, with one end connected by the first reinforcing rod 6 and the other end connected by the second reinforcing rod 14. The first reinforcing rod 6 is placed at the bottom of the two uprights, and the second reinforcing rod 14 is installed at the top of the two uprights with a gap between them.

[0056] The support frame includes legs 71 and longitudinal rods 73. Two legs 71 are erected and arranged in parallel with intervals, and are connected by longitudinal rods 73. A reinforcing rib 72 is installed between the longitudinal rods 73 and the legs 71.

[0057] like Figure 1-3 As shown, the top of the gap between the two legs 71 is open, which allows the first frame and the second frame to swing without being obstructed.

[0058] A reinforcing rib 72 is installed between the longitudinal rod 73 and the support leg 71 to improve the stability of the connection.

[0059] The installation of a first reinforcing rod 6 and a second reinforcing rod 14 between the two uprights ensures that the two uprights stand stably and provides favorable support for the foldable frame.

[0060] It should be noted that when the first frame 8 and the second frame 11 swing downwards, the longitudinal rod 73 can limit the downward swing position of the first frame 8 and the second frame 11. For example, when the width of the foldable frame is the same as the width of the support frame, the telescopic drive causes the first frame 8 and the second frame 11 to swing downwards until they touch the longitudinal rod. The longitudinal rod can then prevent the first frame and the second frame from swinging downwards further, while simultaneously controlling the telescopic drive to stop the first frame from swinging downwards. Alternatively, when the width of the foldable frame is less than the width of the support frame, both ends of the second shaft 103 extend outwards relative to the foldable frame, making the length of the second shaft equal to the width of the support frame. The telescopic drive causes the first frame 8 and the second frame 11 to swing downwards until they touch the longitudinal rod. The longitudinal rod can then prevent the first frame and the second frame from swinging downwards further, while simultaneously controlling the telescopic drive to stop the first frame from swinging downwards.

[0061] One type of telescopic drive component can be a pneumatic cylinder or a hydraulic cylinder. Both pneumatic and hydraulic cylinders can drive the piston to achieve telescopic operation.

[0062] In some alternative embodiments, a hinged connection structure between the telescopic drive and the first frame is provided, such as... Figure 1 As shown, a fifth U-shaped seat 15, a rotating shaft 16, and a second support 17 are added. The fifth U-shaped seat 15 is connected to the piston 51 and is fitted onto the second support 17. The rotating shaft 16 passes through the fifth U-shaped seat 15 and the second support 17. The second support 17 is connected to the first frame 8.

[0063] like Figure 5 As shown, the fifth U-shaped seat 15 is provided with a U-shaped groove 200 and a through hole 100 on the side.

[0064] To facilitate the passage of the rotating shaft 16 through the second support 17, a through hole is provided on one end of the second support 17 into which the fifth U-shaped seat 15 is inserted.

[0065] During installation, the fifth U-shaped seat 15 is fitted onto the second support 17 via a U-shaped groove, and then the pivot 16 passes through the fifth U-shaped seat 15 and the second support 17. The through holes on the fifth U-shaped seat and the second support provide space for the pivot to pass through.

[0066] The fifth U-shaped seat and the second support can swing relative to each other via a pivot.

[0067] like Figure 1 As shown, the bottom support includes a base plate 1, a first support 3, and a support shaft 2. Two vertical plates 4 are erected parallel to each other on the base plate 1. One end of the first support 3 is placed between the two vertical plates 4, and the other end is connected to the telescopic drive component 5. The support shaft 2 passes through the two vertical plates 4 and the first support 3.

[0068] Understandably, in order to facilitate the support shaft passing through the vertical plate and the first support, both the vertical plate 4 and the first support 3 are provided with through holes (not shown in the figure) for the support shaft 2 to pass through.

[0069] During installation, the end of the first support 3 with a through hole is inserted between the two vertical plates 4, and then the support shaft 2 passes through the two vertical plates and the first support. The first support can swing relative to the two vertical plates through the support shaft, so that the telescopic drive 5 can swing relative to the base plate through the first support.

[0070] The working method of this utility model:

[0071] In the initial state, the telescopic drive 5 supports the first frame 8 through the piston 51, so that the first frame 8 and the second frame 11 remain horizontal and aligned with each other.

[0072] The battery tray to be processed is placed on the first frame 8 or the second frame 11, and the upper surface of the battery tray can be processed. When the upper surface processing is completed and it needs to be flipped over, the operator operates the telescopic drive 5, which drives the piston 51 to retract downward. As the piston 51 retracts downward, it causes the first frame 8 to swing downward. The first frame 8 causes the second frame 11 to swing downward as well. As the second frame 11 swings downward, it can slide downward through the sliding mechanism 12. The battery tray on the first frame 8 or the second frame 11 tilts downward accordingly. When the first frame 8 or the second frame 11 swings downward to the required tilt angle or touches the longitudinal rod 73, the operator operates the telescopic drive 5 to stop working, and the piston stops retracting. At this time, the operator can apply a pushing force to the upward tilted end of the battery tray, which can easily push the battery tray from the first frame 8 or the second frame 11 onto the second frame 11 or the first frame 8.

[0073] The operator manipulates the telescopic drive 5 to work, which drives the piston 51 to extend outward. As the piston 51 extends outward, it pushes the first frame 8 to swing upward. The first frame 8 drives the second frame 11 and the battery tray to swing upward. When the first frame 8 and the second frame 11 are aligned, the telescopic drive can be stopped. The telescopic drive keeps the piston supporting the first frame 8, and the first frame 8 drives the second frame 11 to remain in a horizontal state. The battery tray located on the second frame 11 or the first frame 8 can then be processed, thus realizing the flipping of the battery tray.

[0074] This invention allows a single worker to flip the battery tray, replacing the existing method that requires multiple workers to apply force. This avoids delays for other workers due to the flipping process and improves battery tray processing efficiency.

[0075] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
