[0045] In the embodiment, the fiber bundle 12 is embedded in the strap body 11, so that the overall structural performance of the strap body 11 is better and the service life is longer, thereby reducing the replacement frequency of the oil tank strap 10 to a certain extent and reducing the maintenance cost of the oil tank strap 10.
[0046] In an embodiment of the utility model, the fiber bundle 12 can include a plurality of continuous fibers extending in the length direction of the strap body 11.
[0047] In the embodiment, the fiber bundle 12 is composed of a plurality of continuous fibers extending in the length direction of the strap body 11, and the continuous fibers can provide higher tensile strength and stress transfer capability, so that the oil tank strap 10 can better withstand tension in the length direction, thereby further reducing the probability of rupture of the oil tank strap 10 and more reliably fixing the oil tank.
[0048] In the embodiment, the fiber bundle 12 is composed of a plurality of continuous fibers, so that the extensibility of the strap body 11 in the length direction is reduced, thereby avoiding the deformation or elongation of the oil tank strap 10 when the oil tank strap 10 bears the load of the oil tank or other loads, thereby reliably fixing the oil tank, reducing the loosening of the oil tank, and better maintaining the stable structural state of the oil tank assembly 100, thereby making the oil tank assembly 100 operate more stably and safely.

[0050] In an embodiment of the present application, referring to Figure 4 and Figure 6 , the number of the fiber bundles 12 can be multiple, and the multiple fiber bundles 12 are arranged in the strap body 11 in the width direction (such as the left-right direction shown in Figure 4 ) of the strap body 11.
[0051] In the embodiment, the multiple fiber bundles 12 are arranged in the strap body 11 in the width direction of the strap body 11, the multiple fiber bundles 12 can cooperate to structurally reinforce the strap body 11 in the width direction, and the multiple fiber bundles 12 embedded in the strap body 11 are uniformly distributed in the strap body 11, so that the overall structural stability of the strap body 11 and the fiber bundles 12 is better, and the oil tank strap 10 can be more stably and reliably fixed to the oil tank. For example, the number of the fiber bundles 12 can be two, three, four, five, six or the like, and the multiple fiber bundles 12 are embedded in the strap body 11 in the width direction of the strap body 11, and the number of the fiber bundles 12 can be reasonably set according to the use needs and cost factors and the like. Alternatively, the number of the fiber bundles 12 is two.
[0052] In an embodiment of the present application, the strap body 11 and the fiber bundle 12 as a whole can be a pultruded member.
[0053] In the embodiment, the strap body 11 and the fiber bundle 12 are processed and manufactured by pultrusion, which can make the production and processing of the strap body 11 and the fiber bundle 12 more convenient and efficient and lower in cost. Exemplarily, the pultrusion can continuously produce a semi-finished structure of the strap body 11 and the fiber bundle 12, the semi-finished structure is cut to obtain a semi-finished part of the strap body 11 and the fiber bundle 12 required for a single oil tank strap 10, and the semi-finished part is formed into a strap body 11 and a fiber bundle 12 structure of a required shape in a forming die.
[0054] Exemplarily, when producing oil tank straps 10 of different shapes and sizes, the oil tank strap 10 can use the same semi-finished product to obtain different shapes by different forming dies, so that the development cycle of the oil tank strap 10 in the design and development process is shorter, the continuous pultrusion processing makes the production efficiency of the oil tank strap 10 higher, so that the development and production cost of the oil tank strap 10 is lower, and the economy of the oil tank strap 10 is better.
[0055] In an embodiment of the present application, referring to Figure 2 , Figure 8 and Figure 9As shown, the strap body 11 can include a body part 111 and two connecting parts 112, the two connecting parts 112 are connected to the two ends of the body part 111 along the extension direction of the oil tank strap 10 (such as the front-rear direction shown in the figure) respectively, and the connecting part 112 is provided with a mounting hole penetrating the strap body 11 along the thickness direction of the oil tank strap 10 (such as the up-down direction shown in the figure). Figure 2 As shown, the strap body 11 can include a body part 111 and two connecting parts 112, the two connecting parts 112 are connected to the two ends of the body part 111 along the extension direction of the oil tank strap 10 (such as the front-rear direction shown in the figure) respectively, and the connecting part 112 is provided with a mounting hole penetrating the strap body 11 along the thickness direction of the oil tank strap 10 (such as the up-down direction shown in the figure). Figure 9
[0056] In this embodiment, the strap body 11 includes a body part 111 and two connecting parts 112, the two connecting parts 112 are connected to the two ends of the body part 111 along the extension direction of the oil tank strap 10 respectively, and the connecting part 112 is provided with a mounting hole, which is simple in structure and can well meet the use needs of the assembly of the oil tank strap 10 and the lower vehicle body to fix the oil tank. The mounting hole penetrates the strap body 11 along the thickness direction of the oil tank strap 10, which can facilitate the penetration of the fastener through the mounting hole and the assembly and fixation of the lower vehicle body.
[0057] Exemplarily, the number of fiber bundles 12 can be two, and the mounting hole is arranged between the two fiber bundles 12 in the width direction of the oil tank strap 10 in the connecting part 112. In this way, the mounting hole and the fiber bundle 12 can form a relatively symmetrical structure in the width direction of the oil tank strap 10, so that the stress distribution of the connecting part 112 when assembled with the lower vehicle body is more uniform, the structure stability of the connecting part 112 after being connected and fixed with the lower vehicle body is better, and the operation of the oil tank assembly 100 is more stable.
[0058] In an embodiment of the present application, referring to Figure 3 and Figure 9 As shown, the connecting part 112 can be configured to be extruded from the body part 111 along the width direction of the oil tank strap 10, and the connecting part 112 is a solid piece.
[0059] In this embodiment, the connecting part 112 is extruded to form a solid piece through the body part 111, which is convenient to process, and the integrity of the connecting part 112 and the body part 111 is better, so that the fiber bundle 12 embedded in the strap body 11 can be continuously embedded in the connecting part 112 and the body part 111 along the extension direction of the strap body 11, thereby making the overall structure of the strap body 11 and the fiber bundle 12 have good consistency along the extension direction of the strap body 11, and the oil tank strap 10 can be well connected with the lower vehicle body to bind the oil tank with the body part 111.
[0060] The connecting portion 112 is formed as a solid piece in the embodiment, so that the connecting portion 112 can have better structural strength compared with the main body portion 111, so that the connecting portion 112 can have good structural strength at the mounting hole arranged on the connecting portion 112 to bear the fastening force, so that the deformation probability of the connecting portion 112 in the thickness direction is greatly reduced, so that the connecting portion 112 can be stably and reliably assembled and fixed, and so that the oil tank strap 10 can be more stably fixed to the oil tank.
[0061] In some examples of the present application, as shown in Figure 1 and Figure 9 The oil tank strap 10 can further include a reinforcing ring 13, the reinforcing ring 13 extends in a ring shape along the circumference of the mounting hole, and the reinforcing ring 13 is arranged in the mounting hole and fixed to the inner wall surface of the mounting hole.
[0062] In the embodiment, the reinforcing ring 13 is fixed in the mounting hole, so that the structural strength of the mounting hole can be further improved, so that when the oil tank strap 10 is assembled and fixed to the lower vehicle body by the fastening member, the fastening member can stably and reliably connect and fix the connecting portion 112 to the lower vehicle body, so that the connecting portion 112 can better bear the fastening force, so that the structural damage of the connecting portion 112 at the mounting hole can be well reduced, so that the structural stability of the oil tank strap 10 is better, and so that the oil tank assembly 100 can be more stably and reliably fixed to the vehicle by the oil tank strap 10.
[0063] In some examples of the present application, as shown in Figure 4 and Figure 10 The main body portion 111 can be provided with a weight reduction hole 1102. In this way, the weight of the oil tank strap 10 can be further reduced, so that the weight of the oil tank strap 10 is lighter, so that the demand for lightening of the vehicle can be better met.
[0064] In the embodiment, the weight reduction hole 1102 is arranged on the main body portion 111, so that the stress concentration inside the material of the strap main body 11 and the fiber bundle 12 in the pultrusion process can be well reduced, so that a release path is provided for the internal stress, so that the surface shrinkage or depression in the forming process can be well reduced, so that the surface quality of the strap main body 11 and the fiber bundle 12 after pultrusion is better, so that the production and processing of the oil tank strap 10 is more efficient to a certain extent.
[0065] In an example of the present application, as shown in Figure 3 and Figure 10As shown in the drawings, the weight-reducing hole 1102 is formed in the inner portion of the main body part 111 and extends along the length direction of the strap main body 11, the main body part 111 is provided with the assembly hole 1101, the assembly hole 1101 is arranged on one side of the weight-reducing hole 1102 in the thickness direction of the oil tank strap 10, one end of the assembly hole 1101 penetrates through one side surface of the main body part 111, and the other end of the assembly hole 1101 communicates with the weight-reducing hole 1102.
[0066] In the embodiment, the assembly hole 1101 is arranged on the main body part 111, which can facilitate the mounting and fixing of the oil tank strap 10 and the underbody panel of the vehicle, for example, a fastener can pass through the assembly hole 1101 to fasten and connect the underbody panel and the oil tank strap 10, and optionally, the assembly hole 1101 can also be provided with a reinforcing structure according to the needs to improve the connection reliability of the underbody panel and the oil tank strap 10.
[0067] In the embodiment, the assembly hole 1101 is arranged on one side of the oil tank strap 10 in the thickness direction, one end of the assembly hole 1101 penetrates through one side surface of the main body part 111 and the other end communicates with the weight-reducing hole 1102, so that when the assembly hole 1101 is machined on the oil tank strap 10 as needed or the fastener is assembled and connected with the assembly hole 1101, the wall surface of the main body part 111 on the other side of the weight-reducing hole 1102 can block the drilling equipment or the fastener, avoiding the direct contact of the drilling equipment or the fastener with the oil tank, so that the machining of the assembly hole 1101 is more convenient and easy, and the concentrated force applied to the oil tank by the fastener during assembly is avoided, thereby making the machining and arrangement of the assembly hole 1101 on the oil tank strap 10 more convenient, and enabling the oil tank assembly 100 to operate stably.
[0068] In some specific embodiments of the utility model, as shown in Figure 4 and Figure 10 As shown in the drawings, a plurality of fiber bundles 12 can be arranged on both sides of the weight-reducing hole 1102 along the width direction of the strap main body 11. In this way, when the assembly hole 1101 that communicates with the weight-reducing hole 1102 is opened on the main body part 111 along the thickness direction of the strap main body 11, the fiber bundles 12 can always maintain a continuous structure state along the extension direction of the strap main body 11, thereby enabling the oil tank strap 10 to still maintain good tensile strength after the assembly hole 1101 is opened, enabling the oil tank strap 10 to maintain good structural stability during use, and enabling the oil tank strap 10 to stably and reliably cooperate with the assembly of other structures such as the underbody panel and stably and reliably fix the oil tank.
[0069] In an embodiment of the utility model, the width dimension of the weight-reducing hole 1102 along the width direction of the strap main body 11 is greater than or equal to 26 mm and less than or equal to 30 mm.
[0070] In the embodiment, the width dimension of the weight-reducing hole 1102 along the width direction of the strap body 11 is set to be greater than or equal to 26 mm and less than or equal to 30 mm, so that the weight-reducing hole 1102 has a larger width dimension, thereby significantly reducing the weight of the strap body 11, and avoiding that the width dimension of the weight-reducing hole 1102 along the width direction of the strap body 11 is too long, so that the strap body 11 can maintain good structural strength to fix the oil tank. Figure 10 As shown in the figure, d1 represents the width dimension of the weight-reducing hole 1102 along the width direction of the strap body 11, and d1 can be 26 mm, 27 mm, 27.5 mm, 29 mm, 30 mm, etc. The length dimension of the weight-reducing hole 1102 along the width direction of the strap body 11 can be reasonably set according to requirements.
[0071] In some examples of the utility model, the width dimension of the main body part 111 along the width direction of the strap body 11 can be greater than or equal to 40 mm and less than or equal to 50 mm.
[0072] It can be understood that the main body part 111 is embedded with the fiber bundle 12, and the fiber bundle 12 needs to maintain a certain distance from the surface of the main body part 111, so that the strap body 11 and the fiber bundle 12 can be stably and reliably bonded into one body and facilitate the size control after forming when the strap body 11 and the fiber bundle 12 are produced and processed. In the embodiment, the width dimension of the main body part 111 along the width direction of the strap body 11 is set to be greater than or equal to 40 mm, so that the main body part 111 has sufficient embedding area to meet the embedding needs of the fiber bundle 12 even if the weight-reducing hole 1102 is present, so that the strap body 11 and the fiber bundle 12 can be stably and smoothly processed.
[0073] In the embodiment, the width dimension of the main body part 111 along the width direction of the strap body 11 is set to be less than or equal to 50 mm, so that the width dimension of the oil tank strap 10 is smaller, thereby making the overall weight of the oil tank strap 10 lighter, meeting the needs of vehicle lightening.
[0074] For example Figure 10 As shown in the figure, d2 represents the width dimension of the main body part 111 along the width direction of the strap body 11, and d2 can be 40 mm, 41 mm, 42 mm, 43 mm, 44 mm, 45 mm, 48 mm, 50 mm, etc. Preferably, the width dimension of the main body part 111 along the width direction of the strap body 11 can be 45 mm.
[0075] In an embodiment of the utility model, as shown in Figure 10As shown, the thickness dimension of the main body part 111 along the thickness direction of the strap main body 11 can be greater than or equal to 7 mm and less than or equal to 9 mm. In this way, the thickness of the main body part 111 can be sufficient to allow the fiber bundle 12 to be stably and conveniently embedded in the main body part 111, and the main body part 111 can have a smaller thickness and a smaller weight, thereby reducing the overall weight of the oil tank strap 10. For example Figure 10 As shown, h1 in the figure represents the thickness dimension of the main body part 111 along the thickness direction of the strap main body 11, and h1 can be 7 mm, 7.2 mm, 8 mm, 8.5 mm, 9 mm, etc.
[0076] In an embodiment of the present application, the main body part 111 can be formed into a first side wall and a second side wall on both sides of the weight-reducing hole 1102 along the thickness direction of the main body part 111, and the first side wall can be provided with the assembly hole 1101. The wall thickness of the first side wall can be greater than or equal to 2 mm and less than or equal to 3.5 mm. In this way, the thickness of the first side wall can be appropriate to facilitate the opening of the assembly hole 1101 and have good structural strength to facilitate the assembly and fixation of other structures with the oil tank strap 10, and the strap main body 11 can be used more conveniently during assembly and fixation. For example Figure 10 As shown, h2 in the figure represents the thickness dimension of the first side wall, and h2 can be 2 mm, 2.1 mm, 2.3 mm, 2.8 mm, 3 mm, 3.5 mm, etc.
[0077] In some examples of the present application, the thickness dimension of the second side wall can be greater than or equal to 2.5 mm and less than or equal to 3.5 mm. In this way, the second side wall can have sufficient thickness to maintain good structural strength, the strap main body 11 can stably and reliably bind the oil tank, and when the assembly hole 1101 is opened in the first side wall of the main body part 111, the second side wall can stably and reliably separate the oil tank from the drilling equipment, or when the fastener is connected at the assembly hole 1101 to assemble with the bottom guard plate and other structures, the second side wall can stably and reliably separate the oil tank from the fastener, thereby stably and reliably fixing the oil tank during the use and assembly of the oil tank strap 10. For example Figure 10 As shown, h3 in the figure represents the thickness dimension of the second side wall, and h3 can be 2.5 mm, 2.6 mm, 2.8 mm, 3 mm, 3.3 mm, 3.5 mm, etc.

[0086] As shown in FIG. 9, the width of the connecting part 112 along the width direction of the strap body 11 is smaller than that of the main body part 111 after processing. Figure 10 As shown in FIG. 9, the width of the connecting part 112 along the width direction of the strap body 11 is smaller than that of the main body part 111 after processing.
[0087] The connecting part 112 is provided with a mounting hole penetrating the connecting part 112 along the thickness direction of the strap body 11, and the reinforcing ring 13 is a steel part arranged in the mounting hole and abutting against the inner wall of the mounting hole. In the thickness direction of the strap body 11, the main body part 111 can be provided with an assembly hole 1101 communicating with the weight-reducing hole 1102, and the assembly hole 1101 is arranged on one side of the weight-reducing hole 1102.
[0088] The reinforcing plate 20 is a metal plate provided with a communication hole 201, and the reinforcing plate 20 is arranged on one side of the connecting part 112 along the thickness direction, the communication hole 201 communicates with the mounting hole, and the connecting part 112 can be formed with a limiting flange at the end away from the main body part 111 along the extension direction of the strap body 11 to position and assemble the reinforcing plate 20.
[0089] In the process of producing the oil tank strap 10, the composite material of the strap body 11 and the fiber bundle 12 is mixed in a preheating device, so that the thermoplastic resin and the short fibers gradually become in a molten state, the fiber bundle 12 composed of continuous fibers is soaked in the molten thermoplastic resin and short fibers, and the fiber bundle 12 and the molten thermoplastic resin and short fibers as a whole enter a pultrusion die for extrusion. The semi-finished product structure formed after extrusion enters a cooling die to keep the shape. The semi-finished product structure is then pulled by a pulling machine to a cutting device to cut into the required length of the oil tank strap 10, to obtain a semi-finished part of the strap body 11 and the fiber bundle 12. The semi-finished part then enters a forming die to form the required shape, thereby obtaining a semi-finished piece of the strap body 11 and the fiber bundle 12. The two ends of the semi-finished piece in the length direction are formed into the required connecting part 112 by extrusion, thereby obtaining a finished piece of the strap body 11 and the fiber bundle 12. When forming the connecting part 112 at the two ends by extrusion, heating can be performed by infrared heating or the like, so as to eliminate the weight-reducing hole 1102 and form the connecting part 112 with the required shape.
[0090] The finished piece of the strap body 11 and the fiber bundle 12 is machined to form a mounting hole and the reinforcing ring 13 is fixed in the mounting hole by hot pressing, thereby processing the oil tank strap 10.
[0091] When the oil tank assembly 100 is assembled in the vehicle, after the oil tank strap 10 is matched with the oil tank, the reinforcing plate 20 is arranged at the connecting part 112, and the fastener passes through the reinforcing plate 20 and the mounting hole to assemble and fix the oil tank strap 10 with the lower vehicle body, thereby fixing the oil tank assembly 100 in the vehicle. When the oil tank strap 10 needs to be fastened and assembled with other structures, for example, when the oil tank strap 10 is assembled with the underbody panel of the vehicle, the oil tank strap 10 can be provided with an assembly hole 1101 on the body part 111, and the fastener fastens and connects the underbody panel with the oil tank strap 10 through the assembly hole 1101. Of course, the oil tank strap 10 can also not be provided with the assembly hole 1101, and the assembly hole 1101 can be flexibly provided according to actual needs.
[0092] Compared with the traditional steel strap, the oil tank strap 10 in the embodiment is processed and manufactured by using the pultrusion composite material piece, and the body part 111 is provided with the weight-reducing hole 1102, so that the weight of the oil tank strap 10 can be significantly reduced with good economic efficiency, thereby well meeting the needs of the lightweight of the vehicle, and enabling the oil tank strap 10 to be produced by using the same pultrusion die after development and design of different sizes and shapes, and only the cutting length and the forming die need to be adjusted, so that the development cost can be more evenly distributed when the oil tank strap 10 is developed and designed and produced in multiple types, thereby reducing the production cost of the oil tank strap 10 to a certain extent.
[0093] Compared with the aluminum alloy steel belt, the oil tank binding belt 10 in the embodiment has low cost and can have smaller weight, better meeting the needs of vehicle lightening, and the oil tank binding belt 10 in the embodiment has smaller energy consumption in the processing and production process and low carbon emission, better meeting the increasingly stringent carbon emission requirements, and making the oil tank binding belt 10 in the embodiment more environmentally friendly.
