Description

The driving part of sandwich construction

Technical field

The utility model relates generally to sports equipment and makes field, and the driving part that relates in particular to sports equipment is made field.

Background technology

Along with people's motor mindedness improves day by day, people more and more pay attention to sports, the sports events such as baseball, hockey, violent club enjoy people to favor, in this type games, what directly contact with ball is the striking surface of sports equipment, thereby the performance of driving part can cause very large impact to striker.

When driving part contacts with ball, because the movement velocity ratio of ball is very fast, so can produce a larger relativity power to it during ball impact driving part, if its shock-absorbing performance is good not, will produce larger vibrations, vibrations can be passed player back on hand, player's performance is caused to very large impact, and there is larger impulsive force in the club of motion to bat driving part, firm not if driving part is made, it can be than the situation such as being easier to deform, break at square stance.Thereby to consider its shock-absorbing performance, intensity and toughness when making bat driving part.

Summary of the invention

The purpose of this utility model is to design that a kind of intensity and good toughness, shock-absorbing performance are better, also driving part structure preferably of elasticity.

For achieving the above object, the technical solution adopted in the utility model is:

The driving part of sandwich construction, described driving part is at least followed successively by TPU layer, PU layer and support bottom from outside to inside, between described PU layer and support bottom, is also provided with elastomer layer, and described elastomer layer is pasted together and is made moulding by spongy layer and EVA layer.

In the technical program, the adhesive surface of described spongy layer and EVA layer is trapezoidal corrugated.

In the technical program, the adhesive surface of described spongy layer and EVA layer is waveform surface.

In the technical program, described TPU layer forms by two TPU inclusions.

The driving part of sandwich construction, described driving part is at least followed successively by TPU layer, PU layer and support bottom from outside to inside, between described PU layer and support bottom, is also provided with elastomer layer, and described elastomer layer is PU foaming body layer.

In the technical program, described TPU layer forms by two TPU inclusions.

The driving part of sandwich construction, described driving part is followed successively by TPU skin, TPU middle level and support bottom from outside to inside, and the bottom in described TPU middle level evenly offers fluting.

In the technical program, the single fluting cross section in described TPU middle level is arch bridge shape, and TPU middle level is that direct Unitary injection formed is made.

In the technical program, described TPU skin forms by two TPU inclusions.

Compare with conventional art, the utility model has the advantage of:

Because the hardness range of TPU is wider, wear-resisting, good springiness, thereby the TPU layer on driving part design improve the toughness of driving part, be not prone to and break, and shock-absorbing performance is good, wear-resisting, surface is more attractive in appearance.In addition, compared to conventional art, the structure that in the utility model, PU layer combines with elastomer layer, or establish slotted TPU middle level structure, and all make this practical elasticity improve, be easier to ball to impact away.Because TPU layer forms by two TPU inclusions, thereby the shape of the bat driving part that can fit required cuts out, and makes more convenient, and can form Liang Ge pressing district, and inclusion obtains more firm, difficult drop-off.

accompanying drawing explanation:

Below in conjunction with drawings and the specific embodiments, the utility model is described.

Fig. 1 is the structural representation of the one preferred embodiment of the utility model;

Fig. 2 is one of the structural representation of its two preferred embodiment of the utility model;

Fig. 3 be the utility model its two preferred embodiment structural representation two;

Fig. 4 be the utility model its two preferred embodiment structural representation three;

Fig. 5 is the structural representation of its three preferred embodiment of the utility model.

the specific embodiment:

Embodiment 1:

As shown in Figure 1, the structure of the present embodiment is followed successively by from outside to inside: TPU layer 5, PU layer 4 and support bottom 1, tightly fit in together between each layer.

Because the hardness range of TPU is wider, wear-resisting, good springiness, thereby on driving part, the design of TPU layer 5 improves the toughness of driving part, be not prone to and break, and shock-absorbing performance is good, wear-resisting, surface is more attractive in appearance.

Because the hardness of PU is better, in the utility model, the design of PU layer 4 improves the hardness of driving part, and while waving ball, dynamics is better, can ball be impacted fartherly.

TPU layer 5 forms by two TPU inclusions, thereby the shape of the bat driving part that can fit required cuts out, and makes more convenient, and can form Liang Ge pressing district, and inclusion obtains more firm, difficult drop-off.

Embodiment 2:

As shown in Fig. 2 ~ 4, the present embodiment is to have increased elastomer layer on the basis of embodiment 1.Be that in the present embodiment, innermost layer is support bottom 1, the surface volume of support bottom 1 has covered one deck elastomer layer, elastomer layer can be comprised of

spongy layer

2 and 3 combination of EVA layer, elastomer layer also can be comprised of PU foaming body layer 9, the outer volume of elastomer layer has covered one deck PU layer 4, and the outer surface volume of PU layer 4 has covered one deck TPU layer 5, the outermost layer that TPU layer 5 is bat, between each layer, tightly fit together, thus the sandwich construction of formation driving part.

Elastomer layer can be bonded by spongy layer 2 and EVA layer 3, elastomer layer matches with other layers in the utility model after making moulding again, because EVA, PU foaming body and spongy layer are all the good materials of elasticity, the use of interosculating can have more elasticity, shockproof properties is also better, thereby improves the performance of driving part.

Fig. 2 shows the combination of wherein a kind of elastomer layer of the present utility model, and the utility model spongy layer 2 in gonosome layer of being hit by a bullet is that ，Cong Qi cross section, trapezoidal corrugated is seen with the adhesive surface of EVA layer 3, and both adhesive surfaces are a trapezoidal wave.

Fig. 3 shows the combination of wherein a kind of elastomer layer of the present utility model, and the utility model spongy layer 2 in gonosome layer of being hit by a bullet is waveform surface with the adhesive surface of EVA layer 3, and from its cross section, both adhesive surfaces are a wave.

These two kinds of different combinations of Fig. 2 and Fig. 3 are all in order to make both combinations better, and are not easy to occur the situation of displacement mutually, have guaranteed better the performance of product, and these two kinds of different designs can increase the design of product.

Elastomer layer also can be comprised of PU foaming body layer 9, as shown in Figure 4, because the elasticity of PU foaming body is better, thereby can improve elasticity and the shockproof properties of driving part.

Embodiment 2:

As shown in Figure 5, the structure of the present embodiment is followed successively by TPU skin 8, TPU middle level 7 and support bottom 6 from outside to inside, and TPU middle level 7 is direct Unitary injection formeds.The bottom in TPU middle level 7 evenly offers fluting 701, Open Side Down for fluting 701, the cross section of the single fluting 701 in TPU middle level 7 is arch bridge shape, such shape design makes ball when clashing into driving part, TPU middle level 7 occurs also can recover quickly after deformation, elasticity is better, and shock-absorbing well, thereby does not affect player's performance.

Equally, because the hardness range of TPU is wider, wear-resisting, good springiness, thereby on driving part, the design in TPU outer 8 and TPU middle level 7 improves the toughness of driving part, is not prone to and breaks, wear-resisting, surface is more attractive in appearance.

TPU skin 8 forms by two TPU inclusions, thereby the shape of the bat driving part that can fit required cuts out, and makes more convenient, and can form Liang Ge pressing district, and inclusion obtains more firm, difficult drop-off.
