Description

Technical Field

[0001] The utility model relates to an electric surfboard, in particular to a skeleton structure of an electric surfboard. Background Art

[0002] The internal skeleton structure of the existing electric surfboard is complex, and it is mostly made by splicing I-beams and T-beams. The outer shell and various fixing components need to be connected to the skeleton for fixing. The common skeleton is composed of multiple main beams and rib beams spliced into a rectangular frame structure. The length of the main beam is equivalent to the overall length of the skeleton. The rib beams are distributed at the front and rear ends and in multiple middle sections of the main beam, and are all vertically intersecting with the main beam. This rectangular frame skeleton has limitations on the length of the main beam, high material selection requirements and manufacturing costs, and a large amount of waste is generated from the cutting of steel beam raw materials. Further, most of the skeletons on the existing surfboards are flat, lacking extension in the vertical height. When the subsequent injection molding and foaming are used to wrap the skeleton, the small height of the skeleton results in poor support for the foaming material; moreover, the subsequent assembly and fixing of other components of the surfboard are inconvenient. For example, the distance from the installation position of the skeleton is far, and longer bolts are required to fix the connection with the skeleton. Content of the Utility Model

[0003] In order to solve the technical problems such as high material selection requirements, high manufacturing costs and large waste generated from the cutting of steel beam raw materials caused by the long main beam in the internal skeleton of the existing electric surfboard, the utility model provides a skeleton structure of an electric surfboard. The skeleton is composed of multiple short units with smaller lengths spliced together. Each unit is composed of several short-sized beam members spliced together. Each unit body can be produced by using the corner materials of steel beams. The requirement for the single-piece length of the spliced steel beam is reduced, and the manufacturing cost is significantly reduced. The utilization rate of the original steel beam of the same length is increased after truncation, and the waste is less. Further, the skeleton extends in both the length and height directions of the surfboard, providing better support for the foaming material that wraps the skeleton, and making it more convenient for the subsequent assembly and fixing of other components of the surfboard.

[0004] The technical solution adopted by the utility model to solve the technical problems: A skeleton structure of an electric surfboard, including a skeleton body composed of multiple beam members spliced together. The feature is that the skeleton body includes a first unit and a second unit spliced front and back. The first unit and the second unit are respectively composed of several beam members spliced together, and both the first unit and the second unit are rectangular frames. The two long side ends of the rectangle of the first unit are respectively fixedly connected to the two ends of the long side of the rectangle on the second unit. Through the two units connected by front and back splicing, the size of each unit along the length direction of the skeleton can be further shortened, thereby reducing the requirement for the length of the beam members required for splicing the units, reducing the material selection requirements and manufacturing costs, and reducing the waste after the steel beam raw materials are cut and segmented. It becomes possible to use individual short beam members as the rectangular sides of the two units.

[0005] As a further improvement and supplement to the above technical solution, the present utility model adopts the following technical measures: The two long sides of the rectangle of the first unit extend outwards towards the second unit to form corresponding outer rectangles, and the end portions of the two long sides after extension are fixedly connected to the two ends of the long sides of the rectangle of the second unit. By extending out of the rectangle, the two long sides of the first unit are fixedly connected to the two ends of the long sides of the rectangle of the second unit, and the extended end portions of the two long sides are convenient for adjusting cutting, so as to align and connect the first unit and the second unit.

[0006] Furthermore, the long side and the short side of the rectangle of the first unit are vertically offset, and the short side is fixedly connected to the long side through bending portions extending upwards at both ends; the two ends of the long side of the rectangle of the second unit are placed on the short side of the rectangle and fixedly connected thereto. There is a certain height difference between the long sides and the short sides of the two rectangular frames of the first unit and the second unit, making it possible to increase the contact area by side fitting of the beam members. Among them, the short side of the rectangle of the first unit is at the bottom and is fixedly connected to the long side of the rectangle through bending portions extending upwards at both ends; the two ends of the long side of the rectangle of the second unit are placed on the short side of the rectangle and fixedly connected thereto.

[0007] Furthermore, the skeleton body further includes a third unit provided below the second unit. The third unit is composed of two symmetric rear extension components. The rear extension component includes a third long beam parallel to the short side of the rectangle on the second unit, a third vertical plate provided at its front part, and a plate seat provided in the middle. The upper and lower ends of the third vertical plate are respectively fixedly connected to the short side of the rectangle of the second unit and the third long beam, and the plate seat is fixedly connected to the third long beam by a straight edge provided on one side thereof. The skeleton body further includes a third unit composed of two symmetrically distributed rear extension components. By extending the skeleton body through the third unit, the skeleton body becomes more three-dimensional and has extensions in three dimensions of length, width, and height. The third unit can provide reliable support for the foaming material at the tail of the surfboard. Each rear extension component includes a third long beam, a third vertical plate connected to its front part, and a plate seat connected to its middle part. The third vertical plate is used for connecting and fixing the third unit and the second unit, and the plate seat is used for strengthening the support of the foaming material at the tail of the surfboard and as a platform for installing and fixing equipment at the tail of the surfboard, such as the fin arranged at the tail of the surfboard.

[0008] Further, the skeleton body further includes a fourth unit fixedly connected to the front of the first unit. The fourth unit includes symmetrically arranged first and second extension beams on the left and right and a connecting seat connecting the two. The rear ends of the first and second extension beams along their respective extension directions are fixedly connected to both sides of the front end of the first unit in the extension direction. The first and second extension beams extend obliquely forward from their respective rear ends so that the distance between the two gradually decreases. The front ends of the first and second extension beams are fixedly connected to both ends of the connecting seat. The skeleton body further includes a fourth unit connected to the front of the first unit, which includes the first and second extension beams and a connecting seat. The two extension beams extend forward from the two sides of the front end of the first unit connected to the rear end and gradually converge, and the distance between the two extension beams decreases accordingly until the front ends of the two extension beams are respectively connected to both ends of the connecting seat, forming an extended section protruding from the front of the skeleton as a support inside the arc-shaped front end of the surfboard, providing support for the front end of the surfboard that warps during operation.

[0009] Further, both the first and second extension beams are composed of an inclined beam in the front section and a straight beam in the rear section connected. The two straight beams are parallel and facing each other, and a cross beam is connected between the two. The cross beam is perpendicular to the two straight beams. The two inclined beams gradually converge from the rear to the front until the ends of the two inclined beams are fixedly connected to both ends of the connecting seat. Both extension beams are formed by butt-jointing an inclined beam and a straight beam connected in sequence. The two straight beams in the rear section are parallel to each other and are reinforced by a perpendicular cross beam. The two inclined beams in the front section gradually converge from the rear to the front until they are fixedly connected to the connecting seat.

[0010] Further, the inclined beam is composed of two short straight beams spliced by a bending piece. The extension lines of the front and rear ends of the bending piece intersect to form an obtuse angle, and the end of the bending piece is fixedly connected to the butt-jointed short straight beam. The short straight beam at the rear end of the inclined beam is fixedly connected to the straight beam through the bending piece. The inclined beam is formed by splicing two short-sized beam members with a bending piece. By using the angle between the two ends of the bending piece, the inclined beam formed by splicing the beam members is also bent, which not only has a high utilization rate of the workpiece surplus material, but also does not require bending processing of the beam members.

[0011] Further, the skeleton body further includes a fifth unit provided below the first unit. The fifth unit includes two parallel fifth long beams and a plurality of fifth vertical plates. The two ends of the fifth vertical plate are respectively fixedly connected to the fifth long beam and the short side of the rectangle of the first unit. The rear end of the fifth long beam and the front end of the third long beam are fixedly connected by a direct piece, and the extension directions of the fifth long beam and the third long beam are the same. The fifth unit is connected below the first unit and is also connected to the third unit at the same time, further strengthening the skeleton body and making the skeleton body more solid longitudinally.

[0012] Further, two parallel and side-by-side reinforcing beams are connected between the fifth unit and the fourth unit. The front ends of the two reinforcing beams are fixedly connected to the connecting seat, and the rear ends of the two reinforcing beams are respectively fixedly connected to the front ends of the two fifth long beams. The fifth unit and the fourth unit are fixedly connected by the two reinforcing beams.

[0013] Further, circular holes are evenly distributed along the length direction of the beam member. When the strength meets the requirements, opening holes in the beam member can effectively reduce the weight, thereby reducing the weight of the skeleton body and the surfboard. When the foam body is subsequently made to wrap the skeleton, the combination of the foam body and the skeleton is more firm.

[0014] The beneficial technical effects of the present utility model are as follows: The skeleton body is composed of a plurality of units connected by splicing front and back and up and down. The size of the unit along the length direction of the skeleton is shortened, and the required length of the beam member is also shortened accordingly. The requirements for cutting and selecting materials and the manufacturing cost are reduced. At the same time, the short materials after cutting and dividing the steel beam raw materials can also be utilized, reducing waste. Further, the skeleton extends and expands in multiple dimensions such as length, width, and height, making the skeleton more three-dimensional, which better matches the subsequent inner support skeleton of the foam material and is also convenient for the subsequent assembly of the surfboard and the fixation of other components. The skeleton body can be flexibly combined and spliced by selecting different units according to needs to meet the requirements for manufacturing the skeletons of surfboards with different specifications and sizes.

As shown in the figure, the extended ends of the two long sides 1-1 are fixedly connected to the two ends of the long side 2-1 of the rectangle of the second unit 2.

[0021] The skeleton body has two units spliced front and back. The size of each unit along the length direction of the skeleton can be further shortened, so that the length of the beam members required for splicing the units becomes shorter. The material selection requirements and manufacturing costs are reduced accordingly, and the waste of the steel beam raw material after cutting and splitting is reduced. Individual short beam members can also be used as the rectangular sides of the two units. For example, the short side of the rectangle where the first unit is located, the long side and the short side of the rectangle of the second unit.

[0025] The fourth unit 4 includes a left and right symmetrical first extension beam 4-1, a second extension beam 4-2, and a connecting seat 4-3 connecting the two. The rear ends of the first extension beam 4-1 and the second extension beam 4-2 along their respective extension directions are respectively fixedly connected to both sides of the front end of the first unit 1 in the extension direction. The first extension beam 4-1 and the second extension beam 4-2 extend obliquely forward from their respective rear ends so that the distance between the two gradually decreases. The front ends of the first extension beam 4-1 and the second extension beam 4-2 are fixedly connected to both ends of the connecting seat 4-3. The fourth unit serves as an extension section extending forward from the skeleton and acts as a support inside the circular arc end at the front of the surfboard during work, providing support for the warped front end of the surfboard during work.

[0026] As shown in the figure, in this embodiment, both the first extension beam 4-1 and the second extension beam 4-2 are composed of an inclined beam 6 in the front section and a straight beam 7 in the rear section.

The short straight beam at the rear end of the inclined beam 6 is fixedly connected to the straight beam 7 through the bending piece 9. The inclined beam is spliced by two short-sized beam members through a bending piece. Utilizing the angle between the two ends of the bending piece, the inclined beam spliced by the beam members also has a bend, which not only has a high utilization rate of the surplus material of the workpiece, but also does not require bending processing of the beam members.

[0027] The fifth unit 5 includes two parallel fifth long beams 5-1 and a plurality of fifth vertical plates 5-2. The two ends of the fifth vertical plates 5-2 are fixedly connected to the fifth long beams 5-1 and the short sides 1-2 of the rectangle of the first unit 1 respectively.
