Abstract

The utility model provides a compounded central tube of badminton racket, which comprises an aluminum tube and more than one layer of carbon fiber coatings which wraps outer surface of the aluminum tube. The utility model uses the aluminum tube as core of central tube of the badminton racket, and the aluminum tube is wrapped by light, high strength ands high rigidity carbon fiber coating. Through compounding of the carbon fiber coating and the aluminum tube, the utility model reinforces the initially weak aluminum tube without adding extra weight. Therefore, the utility model has the advantages of light weight, adequate strength and strong distortion resistance.

Description

Manage in the compound Badminton racket

Technical field

The utility model relates to a kind of Badminton racket, particularly relates in a kind of compound Badminton racket managing, and it is with advantage in light weight and on-deformable.

Background technology

Please refer to shown in Figure 5ly, mostly pipe is to be made of the tubing (30) of single material in the general existing Badminton racket, as aluminum pipe or steel pipe etc.Yet the tubing of single material (30) often has its other shortcoming and not enough to some extent in the use in the use.Though lighter as aluminum pipe weight, yet its intensity is relatively poor, the flexural deformation of pipe in causing when racket is heavily waved easily and can't returning to the original form.Though and steel pipe has higher intensity and not yielding, but its proportion is more than two times of aluminum pipe, pursuing on the light-weighted market, be difficult for being accepted by the consumer.

Because pipe respectively has its weak point, composite to be applied to that pipe becomes present main flow in the Badminton racket in the Badminton racket of single material.The design of a sheathed aluminum pipe outside an aluminum pipe is generally arranged, please refer to Taiwan and announce " tubular construction among the racket " patent case No. 237671, though pipe weight still can't meet light-weighted requirement fully for light in its purer Badminton racket of being made by steel tube place.

In addition, by managing in the made Badminton racket of carbon fibre composite, be after being coated with the composite of one deck carbon fiber and polymer base material with a core, it is hot-forming to place a molding tool to carry out this core and carbon fibre composite again, in the finish program of loosing core again of moulding core is extracted out, promptly finished the manufacturing of pipe in the carbon fiber Badminton racket.

Yet, owing to need the program of loosing core with pipe in the pure carbon fiber composite manufacturing Badminton racket, so manufacture process is comparatively complicated, therefore manufacturing cost also improves.In addition, because carbon fibre composite costs an arm and a leg, it is high that pipe also causes the price of Badminton racket in the Badminton racket of pure carbon fiber composite, is difficult for being accepted by the consumer.

The utility model content

Because pipe still has weak point in the Badminton racket of existing single material, main purpose of the present utility model is to provide in a kind of compound Badminton racket and manages, and it is with advantage in light weight and on-deformable, and cost of manufacture is lower.

For reaching the above object, the utility model comprises an aluminum pipe and the above carbon fiber clad of one deck, and the carbon fiber clad is coated on the aluminum pipe outer peripheral face.

Preferably, it has the two carbon fiber clads that coincide mutually, and each clad has different carbon fiber directions respectively, and pipe all has suitable intensity at different directions in the Badminton racket of moulding and make.

The accessible concrete effect of the utility model comprises:

1. the utility model is with the core of aluminum pipe as pipe in the Badminton racket, and be coated with light weight and have high strength and the carbon fiber clad of high rigidity at aluminum pipe, compound by carbon fiber clad and aluminum pipe, deficiency with reinforcement aluminum pipe intensity, being unlikely to again increases unnecessary weight, makes the utility model with in light weight and the enough and on-deformable advantages of intensity.

2. the utility model is by the different flexible suitable matched combined with aluminum pipe of carbon fiber, can avoid in the Badminton racket of single material its hardness of pipe to cross problem soft or really up to the mark, creates the excellent handle of Badminton racket.

3. the utility model is after the carbon fiber clad is hot-forming, and aluminum pipe promptly stays in the carbon fiber clad and need not be by the program of loosing core, so can simplify manufacture process of the present utility model, the consumption of reducing work hours.

4. because the relative aluminium alloy of carbon fibre material still belongs to expensive material, therefore the utility model adopts the mode of carbon fiber and aluminium alloy compound can significantly reduce the manufacturing cost of pipe in the Badminton racket, avoids pure the manufacturing in the Badminton racket by carbon fibre material to manage the high cost that is caused.

The specific embodiment

Please refer to Fig. 1 and shown in Figure 2, the preferred embodiment of pipe (10) comprises an aluminum pipe (11) and the above carbon fiber clad (12) of one deck in the compound Badminton racket of the present utility model, aluminum pipe (11) is by the aluminium alloy extruded tubing that is shaped to, and as the core of carbon fiber clad (12); Carbon fiber clad (12) is coated on aluminum pipe (11) outer peripheral face, and the direction of pipe (10) stressed maximum is made optimal fiber alignment in Badminton racket, so that maximum intensity to be provided.

Carbon fiber clad (12) can be carbon fiber combine with polymer base material constitute, the form of carbon fiber can be short fiber, continuous long fiber, braided fiber and flour etc.; Polymer base material can comprise thermoplastic plastic and thermosetting plastic, thermoplastic plastic such as Nylon, PP, PBT, PPO, PC, ABS, PVC etc., thermosetting plastic such as unsaturated polyester resin, epoxy resin, phenol resin etc.

Please with further reference to shown in Figure 3, after carbon fiber clad (12) is coated on aluminum pipe (11) outer peripheral face, be placed on and carry out hot-formingly in a molding tool (20), make carbon fiber clad (12) be incorporated into aluminum pipe (11) and go up and be shaped to pipe (10) in the Badminton racket.

When the utility model preferred embodiment has carbon fiber clad (12) more than two layers, each carbon fiber clad (12) is coincided mutually with different carbon fiber directions, and pipe (10) is subjected to force direction all to have suitable intensity in difference in the Badminton racket of moulding and make.

Preferred embodiment of the present utility model is with the core of aluminum pipe (11) as pipe (10) in the Badminton racket, and be coated with light weight and have high strength and the carbon fiber clad of high rigidity (12) at aluminum pipe (11), compound by carbon fiber clad (12) and aluminum pipe (11) makes this preferred embodiment with in light weight and the enough and on-deformable advantages of intensity.

In addition, because preferred embodiment of the present utility model is constituted with aluminum pipe (11) is compound with carbon fiber clad (12), so after carbon fiber clad (12) is hot-forming, need not be by the program of loosing core, so can simplify the manufacture process of pipe (10) in the Badminton racket.

Prices are rather stiff and owing to carbon fibre material, therefore adopt the mode of carbon fiber and aluminium alloy compound can significantly reduce the manufacturing cost of managing (10) in the Badminton racket, avoid pure and make the high cost that pipe (10) is caused in the Badminton racket by carbon fibre material, in addition, by the flexible suitable collocation of carbon fiber clad (12) with aluminum pipe (11), can avoid in the Badminton racket of single material pipe (10) its hardness to cross problem soft or really up to the mark, create the excellent handle of Badminton racket.
