Description

Technical Field

[0001] The utility model relates to the field of anti-slosh plates built in plastic high-pressure fuel tanks, and particularly to a fixing structure of an anti-slosh plate built in a plastic high-pressure fuel tank. Background Art

[0002] A plastic high-pressure fuel tank is a commonly used oil storage device for automobiles made of plastic, which has the advantages of light weight and high pressure resistance, and is widely used in pure fuel vehicles and new energy hybrid fuel vehicles. When the vehicle brakes during driving, the fuel will impact the inner wall of the plastic high-pressure fuel tank due to sloshing, thus forming a rattling noise, which will further affect driving. To reduce the violent sloshing of the oil in the fuel tank, reduce the impact force, and reduce the noise, an anti-slosh plate is generally built in the fuel tank.

[0003] The anti-slosh plate built in the plastic high-pressure fuel tank is fixed inside the plastic high-pressure fuel tank. In the prior art, by setting a support rod in the fuel tank, a mounting surface is reserved on the support rod, and then the anti-slosh plate is fixed on the above mounting surface through screws and bolts. For example, in the existing patent document "CN213082915U A fixed anti-rotation structure for installing a built-in double anti-slosh plate", a positioning block is set on the support column to provide a mounting position for the anti-slosh plate, and then the anti-slosh plate is fixed through a locking bolt; or a structure similar to a hoop is set on the anti-slosh plate, and when the hoop is fixed on the support rod, the hoop also needs to be fixed through screws or bolts; when installing the anti-slosh plate through the above prior art, during installation, multiple screws or bolts need to be manually tightened, resulting in a large labor intensity during fixed installation and inconvenient installation operation technical problems. Summary of the Utility Model

[0004] The utility model provides a fixing structure of an anti-slosh plate built in a plastic high-pressure fuel tank to solve the technical problem of inconvenient fixed installation of the anti-slosh plate.

[0005] The utility model solves the above technical problems through the following technical solutions:

[0006] The utility model provides a fixing structure of an anti-slosh plate built in a plastic high-pressure fuel tank, including an arc-shaped seat arranged in the middle of the anti-slosh plate; further including: an arc-shaped cover plate, which is connected with the arc-shaped seat through an anti-disengagement plugging mechanism, so that the arc-shaped cover plate and the arc-shaped seat can be quickly clamped and installed on a support rod fixedly connected inside the plastic high-pressure fuel tank; an elastic pressing member, and at least one elastic pressing member is arranged on the joint surface between the arc-shaped seat and the support rod.

[0007] In this technical solution, a support rod installed between the arc-shaped cover plate and the arc-shaped seat inside the plastic high-pressure fuel tank enables quick installation of the arc-shaped cover plate and the arc-shaped seat through an anti-disengagement plugging mechanism. This allows the two to be quickly clamped and installed onto the support rod, improving the installation efficiency and making the installation operation of the anti-wave plate convenient. An elastic pressing member is further provided. When the arc-shaped cover plate and the arc-shaped seat are installed onto the support rod, the elastic pressing member is compressed, generating a compressive deformation and increasing the static friction during the clamping installation to ensure the fixing effect.

[0008] Preferably, the anti-disengagement plugging mechanism includes a slot portion and a T-shaped strip; a T-shaped strip is fixedly installed at each end of the arc-shaped cover plate, and the slot portion includes a seat body provided with a T-shaped groove adapted for the insertion of the T-shaped strip.

[0009] In this technical solution, the anti-disengagement plugging mechanism can achieve the plugging installation between the arc-shaped cover plate and the arc-shaped seat by inserting the T-shaped strip into the T-shaped groove, making the overall installation operation convenient.

[0010] Preferably, the slot portion further includes an anti-disengagement locking block, and an anti-disengagement locking hole for the insertion of the anti-disengagement locking block is provided on the T-shaped strip.

[0011] In this technical solution, after the T-shaped strip is inserted into the T-shaped groove, positioning is carried out by inserting the anti-disengagement locking block into the anti-disengagement locking hole. After the T-shaped strip and the T-shaped groove are plugged, anti-disengagement positioning is provided to prevent the T-shaped strip and the T-shaped groove from disengaging.

[0012] Preferably, the arc-shaped seat is provided with an installation hole, and the installation hole communicates with the T-shaped groove. A spring is arranged in the installation hole, and the anti-disengagement locking block is elastically connected to the hole wall of the installation hole through the spring.

[0013] In this technical solution, the elastic installation of the anti-disengagement locking block is realized through the arrangement of the spring. When the anti-disengagement locking block is pressed, it can be retracted into the installation hole, compressing the spring. When the pressure on the anti-disengagement locking block is removed, the anti-disengagement locking block can protrude from the installation hole through the elastic force of the spring.

[0014] Preferably, one end of the anti-disengagement locking block is in clearance fit with the installation hole. One end of the spring is fixedly connected to the end of the anti-disengagement locking block located inside the installation hole, and the other end of the spring is fixedly connected to the hole wall of the installation hole.

[0015] In this technical solution, through the fixed connection limitations at both ends of the spring, the anti-disengagement locking block and the spring will not disengage from the installation hole.

[0016] Preferably, a first inclined surface is provided at one end of the anti-disengagement locking block located outside the installation hole.

[0017] In this technical solution, the first inclined surface is used to be squeezed by the second inclined surface of the T-shaped strip to push the anti-disengagement locking block into the anti-disengagement locking hole automatically.

[0018] Preferably, a second inclined surface is provided at one end of the T-shaped bar, and the second inclined surface is adapted to the first inclined surface.

[0019] In this technical solution, the second inclined surface is used to adapt to the first inclined surface.

[0020] Preferably, the elastic pressing piece is a rubber block or a silicone block.

[0021] In the technical solution, when the arc-shaped cover plate and the arc-shaped seat are installed on the support rod, the elastic pressure piece is compressed to produce compression deformation, thereby increasing the static friction during the clamping installation and ensuring the fixing effect.

[0022] Preferably, the support rod comprises a rod body and a welding seat; the number of the welding seats is two, and the two welding seats are respectively arranged at two ends of the rod body, and the welding seats are fixedly connected to the inner wall of the plastic high-pressure fuel tank.

[0023] In the technical solution, the welding seat of the support rod and the oil tank are made of the same material, and the support rod and the oil tank are fixed together by a hot-melt process.

[0024] Preferably, the wave-breaking plate comprises a longitudinal plate, a transverse plate and a reinforcement plate; the longitudinal plate is fixedly connected to the transverse plate, and a plurality of uniformly distributed reinforcement plates are fixedly installed between the longitudinal plate and the transverse plate.

[0025] In this technical solution, the overall structure of the wave-breaking plate adopts criss-cross plates, namely longitudinal plates and transverse plates, which can effectively intercept the shaking amplitude of the oil in the oil tank and reduce the sound of the oil hitting the inner wall of the oil tank.

[0026] On the basis of conforming to the common sense in the art, the above-mentioned preferred conditions can be arbitrarily combined to obtain the preferred embodiments of the present utility model.

[0027] The positive and progressive effects of the utility model are:

[0028] The above-mentioned plastic high-pressure fuel tank has a built-in wave-breaking plate fixing structure, which realizes the rapid installation of the arc cover plate and the arc seat through the setting of the anti-detachment plug-in mechanism, so that the two can be quickly clamped and installed on the support rod, thereby improving the installation efficiency. The wave-breaking plate is easy to fix and operate, which is different from the prior art that uses screws, bolts or clamps for fixing; an elastic pressure piece is further provided, and when the arc cover plate and the arc seat are installed on the support rod, the elastic pressure piece is compressed to produce compression deformation, thereby increasing the static friction during the clamping installation and ensuring the fixing effect.

[0044] The present utility model will be further described below by way of embodiments, but the present utility model is not limited to the scope of the described embodiments.

[0045] As Figures 1-7 shown, the plastic high-pressure fuel tank is internally provided with a wave baffle fixing structure, including an arc-shaped seat 2 provided in the middle of the wave baffle 1; further including: an arc-shaped cover plate 6, the arc-shaped cover plate 6 and the arc-shaped seat 2 are connected through an anti-detachment plugging mechanism, so that the arc-shaped cover plate 6 and the arc-shaped seat 2 can be quickly clamped and installed to the support rod 5 fixedly connected inside the plastic high-pressure fuel tank; an elastic pressing member 3, at least one elastic pressing member 3 is provided on the joint surface of the arc-shaped seat 2 and the support rod 5.

[0046] In specific implementation, it is installed on the support rod 5 inside the plastic high-pressure fuel tank between the arc-shaped cover plate 6 and the arc-shaped seat 2. Through the anti-disengagement plugging mechanism, the arc-shaped cover plate 6 and the arc-shaped seat 2 can be quickly installed, so that the two can be quickly clamped and installed on the support rod 5, improving the installation efficiency, and the installation operation of the anti-wave plate 1 is convenient; an elastic pressing member 3 is further provided. When the arc-shaped cover plate 6 and the arc-shaped seat 2 are installed on the support rod 5, the elastic pressing member 3 is pressed and undergoes compressive deformation, increasing the static friction force during the clamping installation and ensuring the fixing effect.

[0047] As Figure 2 , Figure 3 , Figure 5 As shown in

[0048] and 6, as a specific technical solution, the anti-disengagement plugging mechanism includes a slot part 4 and a T-shaped strip 7; a T-shaped strip 7 is fixedly installed at both ends of the arc-shaped cover plate 6, and the slot part 4 includes a seat body 401, and the seat body 401 is provided with a T-shaped groove 402 adapted for the T-shaped strip 7 to be inserted.

[0049] As Figure 3 and 6 show, as a specific technical solution, the slot part 4 further includes an anti-disengagement block 403, and an anti-disengagement hole 701 for the anti-disengagement block 403 to be inserted is opened on the T-shaped strip 7.

[0050] After the T-shaped strip 7 is inserted into the T-shaped groove 402, positioning is carried out by inserting the anti-disengagement block 403 into the anti-disengagement hole 701. After the T-shaped strip 7 and the T-shaped groove 402 are plugged, anti-disengagement positioning is provided to prevent the T-shaped strip 7 and the T-shaped groove 402 from disengaging.

[0051] As Figure 7 shown, as a specific technical solution, the arc-shaped seat 2 is provided with an installation hole 404, and the installation hole 404 is communicated with the T-shaped groove 402. A spring 405 is arranged in the installation hole 404, and the anti-disengagement block 403 is elastically connected to the wall of the installation hole 404 through the spring 405.

[0052] The elastic installation of the anti-disengagement block 403 is realized through the setting of the spring 405. When the anti-disengagement block 403 is pressed, it can be retracted into the installation hole 404, and the spring 405 is compressed. When the anti-disengagement block 403 loses pressure, the anti-disengagement block 403 can be extended from the installation hole 404 through the elastic force of the spring 405.

[0053] As Figure 7As shown, as a specific technical solution, one end of the anti-slip block 403 is clearance-fitted into the mounting hole 404, one end of the spring 405 is fixedly connected to one end of the anti-slip block 403 located in the mounting hole 404, and the other end of the spring 405 is fixedly connected to the hole wall of the mounting hole 404.

[0054] Due to the fixed connection at both ends of the spring 405 , the anti-detachment block 403 and the spring 405 will not detach from the mounting hole 404 .

[0055] like Figure 7 As shown, as a specific technical solution, the anti-dropping block 403 is provided with a first inclined surface at one end outside the mounting hole 404; the T-shaped bar 7 is provided with a second inclined surface at one end, and the second inclined surface is adapted to the first inclined surface.

[0056] The design of the first bevel and the second bevel, such as Figure 7 As shown, during the insertion of the T-bar 7 from the lower end of the T-slot 402, the first inclined surface is pushed by the second inclined surface, which can squeeze the anti-dropping block 403, so that the anti-dropping block 403 moves into the mounting hole 404, and at the same time compresses the spring 405 until the T-bar 7 is completely inserted into the T-slot 402, the anti-dropping block 403 is aligned with the anti-dropping hole 701, the anti-dropping block 403 loses its squeezing, and the elastic force of the spring 405 pushes the anti-dropping block 403 to automatically insert into the anti-dropping hole 701.

[0057] In the above, the process of inserting the anti-dropping block 403 into the anti-dropping hole 701 does not require additional manual operations, and can be automatically achieved by simply inserting the T-bar 7 into the T-slot 402.

[0058] The elastic pressing piece 3 is a rubber block or a silicone block. When the arc cover plate 6 and the arc seat 2 are installed on the support rod 5, the elastic pressing piece 3 is compressed to produce compression deformation, which increases the static friction during the clamping installation and ensures the fixing effect.

[0059] The support rod 5 includes a rod body 501 and a welding seat 502 . There are two welding seats 502 , and the two welding seats 502 are respectively arranged at two ends of the rod body 501 . The welding seats 502 are fixedly connected to the inner wall of the plastic high-pressure fuel tank.

[0060] The welding seat 502 of the support rod 5 is made of the same material as the oil tank, and the support rod 5 and the oil tank are fixed together by a hot-melt process.

[0061] like Figure 2 As shown, the wave-breaking plate 1 includes a longitudinal plate 101 , a transverse plate 102 and a reinforcing plate 103 ; the longitudinal plate 101 is fixedly connected to the transverse plate 102 , and a plurality of uniformly distributed reinforcing plates 103 are fixedly installed between the longitudinal plate 101 and the transverse plate 102 .

[0062] The overall structure of the wave baffle 1 adopts criss-cross plates, namely longitudinal plates 101 and transverse plates 102, which can effectively intercept the sloshing amplitude of the oil in the fuel tank and reduce the sound of the oil slapping against the inner wall of the fuel tank.

[0063] The present utility model is not limited to the above embodiments. No matter what changes are made in its shape or structure, they all fall within the protection scope of the present utility model. The protection scope of the present utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principle and essence of the present utility model, but these changes and modifications all fall within the protection scope of the present utility model.
