Description

Torsion unit and device and its application in the preparation of car clothing

Technical field

The present invention relates to a torsion unit and device and its application in the preparation of car clothing.

Background technique

Torsion is the force that twists an object to deform it. A device that uses torsion to act can be called a torsion device. Many devices involve operations such as spreading, setting up, or collapsing during use. For example, equipment such as tents or awnings is usually a guarantee of safety, comfort, protection, and protection. However, in the process of spreading, setting up or collapsing these devices, the work of spreading, setting up or collapsing is heavy, and it is difficult for a single person to complete independently, and the average consumer is not a professional, and often does not understand How to open, set up or fold these devices well brings a lot of trouble to the operation. If a torsion device can be designed in these devices, the above-mentioned operations of spreading, building or collapsing can be easily completed by using the deforming force of the torsion device, or even the above-mentioned operations of spreading, building or collapsing can be completed through automatic recovery of the structure. Then it can bring greater convenience to the product.

Car clothing, commonly known as car clothing, is an outer clothing made of canvas or other flexible and wear-resistant materials according to the outer dimensions of the car. When used, the car is covered by the outer surface of the car. It is a protective product for automobiles, which can play a good role in protecting car paint and window glass. Especially for high-end cars, regular use of car clothing can extend the service life of car paint and make car paint as bright as new. The car body is composed of body, buckle and spring hook. The front buckle is closed, put in from the head when using it, the rear buckle is open, use the mortise lock (other locks can also be used) to fix the car body and the rear of the car, no special key can not be removed, then Hook the spring hooks on both sides of the car body to the lower edge of the car body to fix the car body firmly on the car body. In addition to the functions of cleaning and sun protection, the car clothing also has a waterproof function, which can prevent the damage of freezing to the vehicle in severe cold weather; effectively prevent the damage to the vehicle from accidental factors such as falling objects, fireworks and firecrackers; effectively prevent the theft of vehicles and accessories .

However, the existing car clothing has two obvious technical defects, one is that the existing car clothing is only composed of sunshade material (cloth), after covering the car, it almost fits the car, the heat dissipation effect is relatively poor, the car clothing Fitting with the car's surface, it can't play a good role in preventing the impact of hail or other hard objects, and its scratch resistance is also weak. Moreover, the existing car clothing requires manual labor to unfold or fold it manually, but because the car body is relatively tall and has a large area, unfolding, covering and folding and storing operations are relatively time-consuming and laborious.

If you can give the car clothing a support frame structure, support it to make the car clothing and the car surface have a little space, use the heat insulation effect of air to play a better sun protection effect, and because of the support structure, form a certain The tension can prevent the hard objects from hitting the car to a certain extent, which will greatly enhance the protective effect of the clothing on the car. However, if the general support structure requires human construction, it is more troublesome and it is not easy to store it. Therefore, there are no reports on related solutions for such technical problems.

The connection structure of the tip can give as little room as possible for the elastic material in the tube, as small as just to allow a little room for the overlapping elastic materials in the connection structure of the end.

Of course, in the second optional solution described above, the elastic material may be several parallel pieces according to the needs of elasticity or torsion.

The twist ring in the present invention may be rectangular, square, circular, elliptical, rhombic or triangular. In the same torsion unit, all the torsion rings may have the same shape, or they may adopt different shapes.

The torsion unit has tensile tension and directional folding force. After the external force is pulled apart, it forms an open shape. If the external force is removed, the torque unit can be automatically recovered to restore the initial state.

The processing method of the torsion unit of the present invention is: processing and molding using elastic materials. The two sets of processed torque units are combined into a set of torque devices with a connecting structure.

The invention provides a torsion device provided with the torsion unit. The torsion device is obtained by connecting more than two torsion units or torsion structures.

The connection of the two or more torsion units may be a longitudinal connection, and different torsion units are connected by several connection structures. Whether it is the foregoing optional solution 1 or optional solution 2, there are more than two connection structures.

Designed on the basis of one of the alternative solutions, if there are three connection structures, then the longitudinal connection method is that one end of the elastic material penetrates from the first connection structure from beginning to end and then from the second connection structure. It runs through from end to end, then from the third connection structure from head to tail, then from the second connection structure from head to tail, and finally from the first connection structure from tail to head, it is connected to the other end of the elastic material. A twisted ring is formed between the position of the adjacent connection structure, the first connection structure and the second connection structure, the second connection structure and the third connection structure, respectively.

Similarly, the connection can be connected by welding or other similar methods; or by using a connection structure at the end, if the connection structure at the end is used, the two ends of the elastic material can be separated in opposite directions Pass through the connection structure of the end and bend to fix the card to the connection structure. The connection structure of the tip can give as little room as possible for the elastic material in the tube, as small as just to allow a little room for the overlapping elastic materials in the connection structure of the end. According to the need of elasticity or torsion, the elastic material may be several parallel pieces.

According to the needs of the elasticity or torsion force, the first elastic material may be several parallel pieces; the second elastic material may be several parallel pieces.

The connection of the two or more torsion units may be a lateral connection, and different torsion units are connected by a connection structure. Preferably, the connection structure is an elastic member, and more preferably, the connection structure is a torsion spring.

Under the concept of the present invention, the torsion device may also be obtained by intersecting a plurality of laterally connected torsion units and a plurality of longitudinally connected torsion units.

The structure of the torque unit and the torque device can easily realize automatic recovery and restoration, which brings good and broad application prospects to the torque unit and the torque device. For example, it is used as a support frame for various covers used in car clothing or daily necessities (such as a fly cover for food dishes, etc.).

Therefore, the present invention also provides a support frame with a torsion spring structure, which includes a torsion spring structure main body, which is obtained by a plurality of the aforementioned torsion units extending continuously in a single direction.

The extension of the several torsion units along a single direction may be understood as extensions along a single longitudinal direction or extensions along a single lateral direction. If it is applied to the car body of a car, it can be understood as extending along the direction of the car from the front to the rear or from the rear to the front.

That is to say, the width and length of the support frame are adapted to the width and length of the car clothing, but the width and length of the support frame can be less than, greater than or equal to the width and length of the car, this design support frame according to needs The width and length of the support frame can be set to be greater than or equal to the width and length of the car for full protection; if it is for rain protection, the width and length of the support frame can be set to be less than the width and length of the car feasible.

The number of the torsion units can be used as a reference based on the total length of each torsion unit along the head and tail of the car and the overall length of the car. The total length of several torsion units can be designed to be less than, greater than or equal to the overall length of the car as needed. The total length of the several torque units can be adapted to the overall length of the car body.

Existing car models include small cars, mini cars, compact cars, mid-range cars, high-end cars, luxury cars, sedan cars, CDV cars, MPV cars, SUVs, etc. When using car clothing, they can be mainly classified as: Cars are typically represented by short cars and SUVs are typically represented by tall cars.

The extension structure is used to support the covering material (shade material, rainproof material, etc.), and the extension structure may be linear, or rectangular, circular, elliptical, trapezoidal, triangular, etc.

The invention also provides a support frame suitable for the car body of a high-class automobile typically represented by an SUV, and includes a torsion spring structure main body. The torsion spring structure main body is composed of two groups. The torsion unit is continuously installed in a single direction, and the two torsion spring structure bodies are correspondingly provided with a collapsible extension structure. The extension structure is used for connecting two sets of torsion spring structure bodies and supporting the covering materials (shading materials, rainproof materials, etc.) together with the two sets of torsion spring structure bodies. The extension structure may be rectangular, circular, elliptical, trapezoidal , Triangle and other frame structures, the frame structure is synchronized with the torsion spring structure.

Based on the support frame for car clothing with a torsion spring structure, the present invention only needs to reasonably combine the support frame with existing conventional covering materials such as sunshade cloth or other sunshade materials or waterproof and fireproof materials to provide a A vehicle clothing provided with a support frame of a torsion spring structure. Of course, there are many materials, for example, the material of the car clothing can be cotton, linen, silk, woolen cloth, leather, chemical fiber, blended fabric, modal, plastic, optical film, composite film, superconducting film, polyester film, nylon film, plastic film One or several components, these can be selected according to need. The support frame and the existing conventional covering material can be combined and connected by pasting, sewing, hooking, buckling or snapping.

The combination method of the support frame and the covering material may be binding, velcro bonding, point or line bonding, and the torsion unit and the extension structure of the support frame are all or partly set into the cloth bag provided on the car clothing. medium. The size of the car cover can cover the car in whole or in part as required.

It should be noted that the rope at the head end of the car body serves to pull to help unfold the car body and hook a certain position of the car frame to fix the entire car body. B Recycling: The rope at the head end of the car is untied, the applied tension is released, and the directional folding force generated by the elastic force of the support frame causes the support frame and the covering material of the car to be folded together, and automatically folded into a folded state, the user only needs to stretch The structure is gathered and bound well, just put it, it is very labor-saving and convenient. It should be noted that, in the case of recycling, when the recycling support frame is not strong enough, it is possible to apply a slight external force slightly to promote smooth recycling.

For the torque unit, refer to the torque unit provided in any one of Embodiments 1 to 4.

The two groups of torsion spring structure bodies are correspondingly provided with collapsible extension structures 5. The extension structure 5 is used for connecting two sets of torsion spring structure bodies 4 and supporting the covering material (shade materials, rainproof materials, etc., not shown in the figure) together with the two sets of torsion spring structure bodies 4. The extension structure 5 may be A rectangular, circular, elliptical, trapezoidal, triangular, etc. frame structure. The frame structure is synchronized with the torsion spring structure body.

The extension structure 5 and the torsion unit in the torsion spring structure main body may be connected by an elastic member 6.

The support frame may further include a fixing structure (not shown in the figure). The fixing structure enables the support frame to be fixed to other objects when unfolded to ensure that the support frame does not automatically retract and collapse during use. The fixing structure may be a rope, stainless steel wire, hook, etc. One end of the fixing structure is connected to the support frame, and the other end is connected to the automobile after the support frame is unfolded.

The method of combining the support frame with the car clothing can be binding, velcro attachment, point or line bonding, and the torsion unit and the extension structure of the support frame are all or partly set into the cloth bag provided on the car clothing. Medium, the size of the car body needs to be able to cover the car as in the prior art.

When in use, the support frame is in a folded state and is restrained by the help of clips or ropes so that it will not be opened. First put the car clothing device in a suitable position in the car, and release the clips or ropes that bind the support frame. When it is released, it automatically opens, driving the attached garments to unfold together, binding or hooking fixed structures such as ropes or hooks to a suitable position on the vehicle frame, and adjusting them slightly to cover the automobile. When you need to put away your clothes, untie the rope or the hook. Due to the effect of tensile tension and directional folding force, the support frames will bring the clothes together and they will automatically fold into a folded state. The user only needs to gather the extension structure. The binding is good, as shown in Fig. 8 (the shading material attached to the support frame in Fig. 8 is not marked), it can be placed, which is very labor-saving and convenient.

Example 6

The present embodiment provides a support frame suitable for the clothing of a short-sized car that is typically represented by a car, as shown in FIGS. 9 and 10. A torsion spring structure body 7 is included, and the torsion spring structure body 7 is composed of a plurality of torsion units extending along the head and tail direction of the automobile. For the torque unit, refer to the torque unit provided in any one of Embodiments 1 to 4 (in FIG. 9, 71 is an elastic material of the torsion unit and 72 is a connection structure).

Extension structures 8 may be respectively provided on both sides of the torsion unit where the torsion spring structure body 7 covers the position of the tail box of the car. The extension structure 8 is used to support a covering material (shading material, rainproof material, etc.), and the extension structure may be linear or rectangular, circular, elliptical, trapezoidal, triangular, etc.

The extension structure may be foldably fixed on both sides of the torsion unit provided in the torsion spring structure main body, or may be foldably connected by an elastic member (not shown in the figure).

The method of combining the support frame with the car clothing can be binding, velcro attachment, point or line adhesion, and the torsion unit and the extension structure 8 (similar to the extension structure) of the support frame are all or partly nested respectively The cloth bags provided on the car clothing are medium, and the size of the car clothing needs to be able to cover the car in the same way as the prior art.

When in use, the support frame is in a folded state and is restrained by the help of clips or ropes so that it will not be opened. First put the car clothing device in a suitable position in the car, and release the clips or ropes that bind the support frame. The torsion of the support frame When it is released, it automatically opens, driving the attached garments to unfold together, binding or hooking fixed structures such as ropes or hooks to a suitable position on the vehicle frame, and adjusting them slightly to cover the automobile. When you need to put away the clothes, untie the rope or the hook. Due to the action of tensile tension and directional folding force, the support frame drives the clothes to be folded together, and the clothes are automatically folded into a folded state. The user only needs to gather the extension structure 8 The binding is good, as shown in Figure 8 (the sunshade material attached to the support frame in Figure 8 is not marked), it can be placed, which is very labor-saving and convenient.

The specific steps are as follows: when in use, A is opened: the car clothing is in a folded state, the tail rope is fixed in the car trunk, the car clothing is taken out, the car trunk is closed, and the car clothing is placed in a suitable position at the rear of the car (at this time The support frame and the clothing are in a folded state), pull the rope at the head end of the clothing, drive the support frame and covering material of the clothing to unfold together, and then hook the rope end to a suitable position (such as the license plate screw) of the vehicle frame The support frame is stretched to generate proper tension (the support frame is stretched with a certain tension) so that the clothing can cover the car stably. It should be noted that the rope at the head end of the car body serves to pull to help unfold the car body and hook a certain position of the car frame to fix the entire car body. B Recycling: The rope at the head end of the car is untied, and the applied tension is released. The directional folding force generated by the elastic force of the support frame causes the support frame and the covering material of the car to be folded together. The structure is gathered and bound well, just put it, it is very labor-saving and convenient. It should be noted that, in the case of recycling, when the recycling support frame is not strong enough, it is possible to apply a slight external force slightly to promote smooth recycling.
