Description

Technical Field

[0001] Embodiments of the present disclosure relate to a handle and a vehicle. Background Art

[0002] For bicycles, motorcycles, and other cyclists, grip covers are often installed on metal handlebars to improve grip comfort. For example, grip covers can enhance friction between the hand and the metal handlebar, preventing slippage, and effectively isolate the heat transfer from the metal handlebar to the hand in extreme weather. However, existing grip covers are typically made of a single elastic material and fail to meet diverse functional requirements. Utility Model Content

[0003] The purpose of the present disclosure is to provide a handle and a vehicle to at least partially solve the above problems.

[0004] In a first aspect of the present disclosure, a handlebar cover is provided, comprising at least two layers of covers, the at least two layers of covers defining a cavity for accommodating a handlebar, the at least two layers of covers comprising a first cover that is radially the innermost layer and a second cover that is radially the outermost layer, wherein the material hardness of the first cover is greater than the material hardness of the second cover, and wherein the first cover comprises a body and an adhesive layer, the adhesive layer being located on an inner circumferential wall of the body in contact with the handlebar.

[0005] In some embodiments, the at least two layers of the casing are integrally formed by injection molding, and / or, in each two adjacent layers of the casing, the material hardness of the casing located in the inner layer is greater than the material hardness of the casing located in the outer layer.

[0006] In some embodiments, the adhesive layer is formed by precipitation from the main body at least when the temperature of the first casing is higher than a threshold temperature.

[0007] In some embodiments, the grip includes two layers of the cover, and both layers of the cover are made of polyvinyl chloride material.

[0008] In some embodiments, the material of each layer of the sleeve is selected from at least one of polyvinyl chloride, rubber, polypropylene, and thermoplastic elastomer materials.

[0009] In some embodiments, the shape of the outer contour of the second sleeve matches the shape of a hand grip.

[0010] In some embodiments, the outer peripheral wall of the second sleeve is provided with a plurality of groove-shaped structures extending in the circumferential direction, and the plurality of groove-shaped structures are arranged at intervals in the axial direction of the second sleeve.

[0011] In some embodiments, the thickness of the peripheral wall of the first housing ranges from 1 mm to 8 mm.

[0012] In some embodiments, the cavity includes an opening portion and a bottom portion that are opposite to each other in the axial direction, the opening portion is for inserting the handlebar into the cavity, and the bottom portion is used to limit the insertion depth of the handlebar.

[0013] In some embodiments, the bottom is provided with ventilation holes.

[0014] In a second aspect of the present disclosure, a vehicle is provided, comprising a frame having a handlebar, wherein the handlebar is mounted in a cavity of the grip cover according to the first aspect of the present disclosure.

[0015] In the disclosed embodiment, the material hardness of the inner first cover of the grip cover is greater than that of the outer second cover. This facilitates the grip cover to be attached to the handlebar while also providing good support and grip comfort. Furthermore, the first cover can be adhered to the handlebar via an adhesive layer, which helps improve the grip cover's pull-off force and prevents it from falling off the handlebar.

[0016] It should be understood that the content described in this content section is not intended to limit the key features or important features of the embodiments of the present disclosure, nor is it intended to limit the scope of the present disclosure. Other features of the present disclosure will become easily understood through the following description. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The preferred embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although preferred embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided to make the present disclosure more thorough and complete, and to fully convey the scope of the present disclosure to those skilled in the art.

[0021] As used herein, the term "including" and its variations represent open inclusion, i.e., "including but not limited to." Unless otherwise stated, the term "or" means "and / or." The term "based on" means "based at least in part on." The terms "one example embodiment" and "an embodiment" mean "at least one example embodiment." The term "another embodiment" means "at least one additional embodiment." The terms "first," "second," etc. may refer to different or identical objects.

[0022] As described above, the existing grips are usually made of a single elastic material and cannot meet more functional requirements. The embodiment of the present disclosure provides a grip 100 and a vehicle including the grip 100, which can meet more functional requirements. Figure 1 and Figure 2 The principles of the present disclosure are described.

[0023] Figure 1 FIG. 1 shows a perspective schematic diagram of a grip cover 100 according to an embodiment of the present disclosure. Figure 2 The structure of the grip 100 is shown in a cross-sectional view.

[0024] See also Figure 1 and Figure 2 In the illustrated embodiment of the grip cover 100, the grip cover 100 comprises two layers of casing, which define a chamber 110 for accommodating a handlebar of a cycling vehicle (not shown). The chamber 110 has a centerline XX, and the direction extending from the centerline XX may also be referred to as the axial direction of each casing of the grip cover 100.

[0025] The two-layer cover of the grip cover 100 specifically includes a first cover 11 in the radially inner layer and a second cover 12 in the outer layer. The first cover 11 and the second cover 12 can be integrally formed, for example, by double injection molding, so that the two layers of the grip cover 100 can be firmly combined together.

[0026] In some embodiments, the first housing 11 is tubular. Figure 2 In some embodiments, the first sleeve 11 may include a circular tube portion 11a and an end cover portion 11b. One end of the circular tube portion 11a is open, and the other end may be completely or partially closed by the end cover portion 11b.

[0027] The second housing 12 is tubular and covers the outside of the first housing 11. Figure 2In some embodiments, the second casing 12 may include a tubular portion 12a and an end cap portion 12b. The tubular portion 12a of the second casing 12 may completely or partially cover the circular tubular portion 11a of the first casing 11, and the end cap portion 12b of the second casing 12 may completely or partially cover the end cap portion 11b of the first casing 11.

[0028] See also Figure 2 The chamber 110 is specifically defined by the first tubular body 11. The chamber 110 includes an opening portion 1101 and a bottom portion 1102 that are opposite to each other in the axial direction. The opening portion 1101 is located at one end of the first sleeve 11, corresponding to the open end of the circular tube portion 11a, for the handlebar to be inserted into the chamber 110. The bottom portion 1102 is formed by the end cover portion 11b of the first sleeve 11. When the handlebar is inserted into the chamber 110 from the opening 1101, the end of the handlebar abuts against the bottom portion 1102 of the chamber 110, which limits the insertion depth of the handlebar in the chamber 110, thereby making it easier for the user to determine whether the handlebar is fully inserted.

[0029] Of course, the structures of the first and second sleeves 11, 12 are not limited to the above examples. For example, in some alternative embodiments, the first sleeve 11 may not be provided with the end cap 11b, and the other end of the circular tube 11a may be completely or partially enclosed by the end cap 12b of the second sleeve 12. Accordingly, the bottom 1102 of the chamber 110 may be formed by the end cap 12b of the second sleeve 12. Alternatively, in some alternative embodiments, the first sleeve 11 may be provided with the end cap 11b, while the second sleeve 12 may not be provided with the end cap 12b, or the end cap 12b of the second sleeve 12 may not completely cover the end cap 11b of the first sleeve 11, thereby allowing the end cap 11b to be exposed. Alternatively, in some alternative embodiments, neither layer of the handlebar cover 100 is provided with an end cap, allowing the end of the handlebar to be exposed.

[0030] In some embodiments, the wall thickness T of the first sleeve 11 can be substantially uniform. For example, the wall thickness T of the circular tube portion 11a and the wall thickness of the end cover portion 11b can be uniform. Alternatively, in some embodiments, the wall thickness T of the circular tube portion 11a is uniform, and the wall thickness of the end cover portion 11b is uniform, but the wall thickness of the circular tube portion 11a is different from the wall thickness of the end cover portion 11b. In some embodiments, the wall thickness T of the peripheral wall of the first sleeve 11 (more specifically, the circular tube portion 11a) ranges from 1 mm to 8 mm. Of course, the range of the wall thickness T of the peripheral wall of the first sleeve 11 is not limited to this, but can be adjusted according to actual needs.

[0031] In some embodiments, the second cover body 12 may be irregularly shaped. For example, the outer contour of the second cover body 12 may match the shape of a hand grip to enhance the user's comfort when gripping the grip 100 .

[0032] In some embodiments, the outer peripheral wall of the second cover body 12 may be provided with a plurality of groove structures 120 extending in the circumferential direction, and the plurality of groove structures 120 are spaced apart in the axial direction of the second cover body 12. The plurality of groove structures 120 help to increase the friction when the hand grips 100, further preventing slipping.

[0033] In some embodiments, the material hardness of the first cover 11 is greater than the material hardness of the second cover 12. More specifically, the material hardness of the first cover 11 can be made relatively hard. When the grip is attached to the handlebar, the relatively hard first cover 11 will deform less when subjected to force, making it easier to install on the handlebar and also improving the grip's support for the hand. The material hardness of the second cover 12 can be made relatively soft to improve the feel and grip comfort.

[0034] In some embodiments, the bottom 1102 of the chamber 110 is provided with a vent 1103 . When the handlebar is inserted into the chamber 110 , the gas between the handlebar end and the bottom 1102 of the chamber 110 can be discharged through the vent 1103 .

[0035] In some embodiments, the first and second housings 11, 12 can be injection molded from polyvinyl chloride materials (hereinafter referred to as PVC materials) having different compositions. More specifically, for example, the first housing 11 is first injection molded using a PVC material having one composition, and then a PVC material having another composition is injection molded over the first housing 11 to form the second housing 12. Although the specific compositions of the materials of the first and second housings 11, 12 are different, they are both PVC-type materials. After being integrated through injection molding, the first and second housings 11, 12 are well bonded and not easily separated from each other.

[0036] Of course, in some alternative embodiments, the material selection for each cover of grip cover 100 is not limited to PVC. For example, any suitable material such as rubber, polypropylene (PP), thermoplastic elastomer (TPE) can also be used. In some embodiments, different covers of grip cover 100 can be made of the same type of material with different components. In some alternative embodiments, different covers of grip cover 100 can be made of different types of materials. For example, first cover 11 can be made of PP, and second cover 12 can be made of PVC.

[0037] In some embodiments, the main material of the first cover 11 can precipitate a viscous substance, which can form a viscous layer on the inner peripheral wall 111 of the first cover 11 that contacts the handlebars, so that the first cover 11 includes a main body and a viscous layer. This viscous layer can adhere to the metal handlebar, helping to increase the pull-off force of the grip cover 100 and making it difficult for the grip cover 100 to fall off the handlebar. In addition, the adhesion of the viscous layer can hinder the rotation of the grip cover 100 relative to the handlebar, helping to ensure that the grip cover remains in the correct position during riding. Thus, without the addition of other structures, the bonding strength between the first cover 11 and the handlebar can be increased through the material properties of the first cover 11 itself.

[0038] In some embodiments, when both the first and second housings 11, 12 are made of PVC material, the first housing 11 can be made of a low-grade PVC material. Low-grade PVC materials will precipitate viscous substances when the temperature rises to a threshold temperature. For example, when riding a vehicle in a high-temperature environment, the inner wall 111 of the main body of the first housing 11 is subjected to a high temperature transmitted by the metal handlebars. When the temperature at the inner wall 111 is higher than the threshold temperature at which viscous substances precipitate from the main body of the first housing 11, due to the volatilization of additives (including but not limited to softeners and plasticizers) of the PVC material, the surface of the inner wall 111 forms a viscous layer by precipitating viscous substances. The second housing 12 can be made of a high-grade PVC material. High-grade PVC materials are essentially non-precipitating and non-polluting in a high-temperature environment, and will not stain the user's hands after contact with them.

[0039] The grade of PVC material is related to its impurity content (including but not limited to additives) and other indicators. Generally speaking, low-grade PVC material has high impurity content and is prone to precipitating sticky substances when heated, resulting in lower cost. High-grade PVC material has low impurity content (including but not limited to additives) and is less likely to precipitate sticky substances, resulting in higher cost.

[0040] The disclosed embodiments utilize the properties of different grades of PVC to create grip 100, balancing cost, functionality, and practicality. Of course, in other embodiments, the materials of first and second grips 11, 12 are not limited to PVC; any material can be selected as long as it achieves the objectives of the disclosed invention.

[0041] In some alternative embodiments, an adhesive layer may be provided on the inner peripheral wall 111 of the first housing 11, which is also within the scope of protection of the present disclosure. The adhesive layer may be provided on the inner peripheral wall 111 of the first housing 11, for example, by coating. Of course, in some alternative embodiments, the adhesive layer may also be provided on the inner peripheral wall 111 by other suitable means.

[0042] When the handlebar cover 100 is sleeved on the handlebar, the handlebar cover 100 can be firmly bonded to the metal handlebar through the adhesive layer. The adhesive layer can improve the pull-off force of the handlebar cover 100 and hinder the rotation of the handlebar cover 100 relative to the handlebar.

[0043] In some embodiments, the inner circumferential wall 111 of the first housing 11 is completely coated with an adhesive layer. When the inner circumferential wall 111 of the first housing 11 is completely coated with an adhesive layer, the material of the first housing 11 may not be a material that can release sticky substances.

[0044] In some embodiments, an adhesive layer may be applied to a portion of the inner circumferential wall 111 of the first cover 11. In this case, the material of the first cover 11 may be a material that can release a viscous substance. The viscous substance released by the first cover 11 cooperates with the adhesive layer to firmly adhere the handlebar cover 100 to the handlebar.

[0045] In some embodiments, after the grip cover 100 is put on the handlebar, the adhesive layer can be firmly bonded between the handlebar and the grip cover 100 by heating with hot air.

[0046] It should be noted that while the grip cover 100 in the above embodiment is illustrated as having a two-layer cover, the present disclosure is not limited thereto. For example, in some alternative embodiments, the grip cover 100 may include three or more layers, and the multi-layer cover may be integrally formed by injection molding. The multi-layer cover includes a radially innermost first cover 11, a radially outermost second cover 12, and an intermediate cover positioned between the first cover 11 and the second cover 12.

[0047] In some embodiments, in each of two adjacent layers of casing, the material hardness of the casing located in the inner layer is greater than the material hardness of the casing located in the outer layer. Of course, the present disclosure is not limited to this. For example, in some alternative embodiments, the material hardness of each casing of the multi-layer casing can be designed as needed.

[0048] According to an embodiment of the present disclosure, there is further provided a vehicle, which includes a frame having a handlebar, and the handlebar is mounted in a cavity 110 of a grip cover 100 according to an embodiment of the present disclosure.

[0049] In the embodiment disclosed herein, the material hardness of the inner first cover 11 is greater than that of the outer second cover 12. This allows the grip cover 100 to be easily attached to the handlebar while also providing good support and grip comfort. Furthermore, the first cover 11 can be adhered to the handlebar via an adhesive layer, which helps improve the pull-off force of the grip cover 100 and prevents it from falling off the handlebar.

[0050] While various embodiments of the present disclosure have been described above, the above descriptions are illustrative, non-exhaustive, and not intended to be limiting of the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is selected to best explain the principles of the embodiments, their practical applications, or technological improvements in the marketplace, or to enable other persons skilled in the art to understand the embodiments disclosed herein.
