Description

Technical Field

[0001] The present disclosure relates to the technical field of packaging and transportation, and in particular to a plastic protective belt for a clip strip and a clip strip assembly including the protective belt, which is particularly suitable for providing support and protection to a clip strip attached to a vehicle window glass during transportation, for example. Background Art

[0002] When the window glass of a car, such as a front windshield, is mounted on a body sheet metal, a clip is provided between the lower edge of the front windshield in a substantially vertical direction and a vehicle component, such as a ventilation trim, to achieve shock absorption, noise reduction, and waterproofing. The clip of the front windshield currently available on the market is usually configured with a clip groove at one end for matching with a clip hook of, for example, a ventilation trim, and a fitting portion at the other end for matching with the front windshield, and the front windshield is fixed by, for example, an adhesive tape.

[0003] Before the windshield is transported to the automobile assembly manufacturer, a clip is usually pre-attached to the lower edge of the windshield. Due to the large size and fragile nature of the windshield, in order to prevent the windshield from being damaged due to excessive pressure, the windshield is usually transported in a vertical position using a glass carrier. During transportation, due to the weight of the windshield itself or the vibration during transportation, the clip may be deformed or even damaged, which will affect the subsequent cooperation with the hook of the ventilation trim. Therefore, it is necessary to embed a protective strip in the slot of the clip to prevent the slot from being deformed or damaged during transportation. During the insertion process, the operator usually applies force to the protective strip to deform it and enter the slot, and then abut against the slot to provide support. When the windshield is delivered to the automobile assembly manufacturer and installed on the body sheet metal, the protective tape needs to be removed. At this time, due to the close mechanical fit between the protective tape and the clip strip and the lack of a suitable position for the operator to apply a clamping force or a holding force, it is difficult to easily remove the protective tape. The operator often needs to apply a large pulling force or use additional tools, which may cause damage to surrounding vehicle parts or vehicle surfaces, and may even cause injury to the operator. Therefore, it is desirable to provide a labor-saving protective tape that can be easily inserted and removed without tools in a cost-effective and easy-to-implement manner. Summary of the invention

[0004] The purpose of the present disclosure is to provide a protective belt for a clip strip, which is particularly suitable for providing support and protection to the clip strip during transportation of a vehicle window glass such as a windshield, and can be easily removed from a clip slot of the clip strip without any tools.

DETAILED DESCRIPTION

[0055] The implementation and use of the embodiments are discussed in detail below. However, it should be understood that the specific embodiments discussed are merely exemplary of specific ways to implement and use the present disclosure, and are not intended to limit the scope of the present disclosure. When describing the structural positions of the various components, such as up, down, top, bottom, etc., the expressions of directions are not absolute, but relative. When the various components are arranged as shown in the figure, these directional expressions are appropriate, but when the positions of the various components in the figure change, these directional expressions also change accordingly.

[0056] Herein, the expression "includes" or similar expressions "having" and the like are open-ended and do not exclude additional unrecited elements, steps or components.

[0057] As used herein, “plurality” means two or more than two, unless otherwise clearly and specifically defined.

[0058] In this document, unless otherwise specifically defined, the terms "installation", "connection" or "attachment" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meanings of the above terms in this document can be understood according to the specific circumstances.

[0059] With the increasing development of the automobile industry, for larger-sized window glass, such as windshield, manufacturers or users are more concerned about how to reduce or avoid glass breakage rate during transportation, and how to reduce transportation costs. When installed on the body sheet metal, a card strip (also called a lower card strip / seal strip / card-joined profile strip / connecting component, etc.) is usually provided between the lower edge of the front windshield in the roughly vertical direction and the corresponding matching parts of the vehicle (such as ventilation trim (cover) / air conditioning air intake grille, water tank cover / water tank cover of the water storage device, etc.) to achieve the connection between the front windshield and the matching parts, shock absorption, noise reduction and waterproofing. The inventors realize that the card strip is usually an extruded profile, which may be deformed or damaged during transportation due to the weight of the windshield or vibration during transportation. In order to avoid deformation or damage of the card strip that is usually pre-attached to the windshield, a protective strip will be embedded in the card slot of the card strip. When the protective strip needs to be removed, it is difficult to remove due to the close mechanical fit between the protective strip and the card slot, which increases manpower and material resources, and may even cause damage to vehicle parts or operators. Based on this, the present disclosure aims to provide a protective tape that can be easily removed without tools.

[0060] In this article, "strip" and "band" mean a generally elongated component, and the protective band is embedded in at least most of the length of the card slot of the card strip, and is advantageously embedded in the entire length of the card slot. "Width" is a dimension measured in a direction perpendicular to the length direction, and "cross-section" is a plane intercepted along the width of a generally elongated component (such as a card strip or a protective band). The shape of the cross-section is roughly the same along the entire length direction of the component. "Vertical direction" refers to a direction roughly perpendicular to the ground.

[0061] In the following description, the protective tape is applied to the front windshield. It should be understood that the vehicle window glasses suitable for the protective tape and clip strip assembly of the present disclosure include but are not limited to the front windshield glass, the rear windshield glass and other vehicle window glasses. In addition, it is not excluded that the protective tape of the present disclosure is applied to any suitable transportation environment of glass plates with special-shaped structures to provide support and protection for the clip strip attached to the glass plates.

[0062] Figure 1 and Figure 2 The protective tapes 100 and 200 according to different embodiments of the present disclosure are shown respectively. Figure 1The protective band 100 shown includes an embedding portion suitable for embedding in the card slot of the card strip, the embedding portion has an embedding end 110 and is configured to include a first leg 120 and a second leg 130 extending in the same direction and in the same direction from the embedding end 110, respectively, and a gap is formed between the first leg 120 and the second leg 130, so that the first leg 120 and the second leg 130 can be close to each other or separated from each other. It should be understood that for the first leg and the second leg of different configurations, the width dimension of the gap formed between the two is not necessarily a fixed value. For example, when the first leg and the second leg (the relative parts) extend parallel to each other, the width dimension of the gap can be kept roughly consistent, that is, it can be considered as a fixed value; when the first leg and the second leg (the relative parts) extend non-parallel to each other, the width dimension of the gap changes accordingly with the change of the distance between the two (the relative parts). In this article, "roughly consistent" covers the two compared to be completely consistent and the two have slight differences.

[0063] Herein, the situation in which the first leg and the second leg are close to each other may include, for example, the situation when an operating force is applied to the first leg and / or the second leg, and the situation in which the first leg and the second leg are embedded in the card slot and abut against the embedded opening of the card slot and are subjected to abutment force, which may also be referred to as a force-bearing state. The situation in which the first leg and the second leg are separated from each other may include, for example, the situation after the operating force or abutment force applied to the first leg and the second leg is removed, and the situation in which the first leg and the second leg are restored to the initial state, which may also be referred to as a release state. In the release state, the gap between the first leg and the second leg, which is reduced in width due to the force, tends to return to the initial size, and the width of the gap no longer changes after returning to the initial size, that is, it is in a fully released state. Alternatively, in the fully released state (i.e., in the initial size or restored to the initial size), the initial width of the gap may be 0.2mm to 0.5mm, such as 0.3mm, for example, it may be applicable to a card slot with an embedded opening width of 1.2mm to 2.5mm, such as 1.5mm to 2mm. It should be understood that for card slots of different forms or sizes, the width of the gap can be set as required.

[0064] In some embodiments, the first leg 120 and the second leg 130 extend substantially parallel to each other from the embedding end 110, that is, the gap formed between the portions extending substantially parallel to each other in the fully released state maintains a substantially uniform width. In some embodiments, the gap is a first gap G1 between the portions of the first leg 120 and the second leg 130 extending substantially parallel to each other, such as Figure 1As shown, in the fully released state, the initial width d1 of the first gap G1 may be 0.2 mm to 0.5 mm, for example 0.3 mm. Here, the initial width d1 of the first gap G1 refers to the minimum dimension between the first leg 120 and the second leg 130. In some embodiments, the first leg 120 and / or the second leg 130 extends obliquely away from the distal end of the embedding end 110 to form an enlarged second gap between the first leg 120 and the second leg 130, Figure 1 The second gap G2 formed by extending the distal end of the second leg 130 obliquely is exemplarily shown. Alternatively, in the fully released state, the initial width d2 of the second gap G2 may be 1 mm to 2 mm, for example, 1.6 mm. Here, the initial width d2 of the second gap G2 refers to the maximum dimension between the first leg 120 and the second leg 130. The obliquely extended legs can better match the shape of the embedded portion with the shape of the embedded opening of the card slot, so as to better maintain the stable clamping between the two after the embedded portion is embedded in the card slot, further ensuring the support and protection of the card slot. In addition, the obliquely extended legs help the operator to intuitively feel the change in the gap between the first leg 120 and the second leg 130 when applying force, so as to further accurately implement the embedding and removal operations of the protective belt.

[0065] Combination Figure 3 and Figure 5 As shown, one end (the right end in the figure) of the clip strip 300 is configured with a clip slot 310 that matches with a matching part (such as a ventilation trim (cover) / air conditioning grille, a water tank cover / water tank cover of a water storage device, etc.), and the other end is configured as a fitting part 340 that matches with the windshield 500, and the windshield 500 is fixed by, for example, an adhesive tape 400. In some embodiments, the clip strip 300 may also include a support rib 350, and the support rib 350 is, for example, located at Figure 3 The bottom of the clip strip 300 shown in the figure may be attached with a soft structure to be closely connected with the vehicle body, providing sufficient support for the clip strip 300, and having the functions of energy absorption and shock reduction, and improving shock absorption and noise reduction. Before transporting the windshield 500, the embedded portion of the protective belt 100 is suitable for being embedded in the card slot 310 of the clip strip 300 and being held therein, so as to support the embedding opening 311 of the card slot 310 during the transportation of the windshield, and prevent the embedding opening 311 from being deformed or damaged due to the weight of the windshield or vibration during transportation. In the illustrated clip strip 300, the embedding opening 311 of the card slot 310 is defined by the embedded portions facing each other, and the embedded portions can be constructed in the form of any one or any combination of hooks, bumps, ribs, etc. according to different needs. Figure 3Taking the first rib 320 and the second rib 330 protruding toward each other as an example, it should be understood that based on different forms of the card strip, the form of the card slot and its embedding opening may also have different variations. The embedded portion of the protective band 100 advantageously has a limiting structure adapted to the embedding opening of the card slot, so as to limit the position in the card slot and further enhance the retaining effect.

[0066] After the windshield glass with the clip strip attached is transported to the automobile assembly manufacturer, the windshield glass needs to be installed on the body sheet metal 600. At this time, the protection tape 100 needs to be removed from the clip slot 310 so as to be suitable for the following steps: Figure 7 The hook 710 of the ventilation trim 700 shown, for example, is inserted into the card slot 310. At this time, compared with the existing protective belt, the protective belt 100 of the present disclosure can reduce the interference between the first leg 120 and the second leg 130 and the embedding opening 311 of the card slot 310 by applying force to the first leg 120 and / or the second leg 130 so that the first leg 120 and the second leg 130 are close to each other under the action of the operating force, so as to remove the embedding portion from the card slot with only a small extraction force and without any tools, which significantly improves the efficiency of removing the protective belt from the card slot of the card strip. From another perspective, the first leg 120 and the second leg 130 that are close to each other under the action of the operating force are also convenient for embedding into the card slot with a small insertion force, which significantly improves the efficiency of embedding the protective belt into the card slot. In addition, compared with applying a extraction force from one end of the protective belt along its length, the design of the present disclosure facilitates the operator to apply a smaller and more balanced extraction force, and the removal of the protective belt is more convenient and quick.

[0067] As described above, when an operating force is applied to the first leg 120 and / or the second leg 130 to bring the first leg 120 and the second leg 130 closer to each other, that is, when the protective tape 100 needs to be inserted into the card slot and when the protective tape 100 needs to be removed from the card slot, the first leg 120 and the second leg 130 can contact each other (that is, the initial width d1 of the first gap G1 is reduced to zero), or the initial width d1 of the first gap G1 can be reduced by at least 50%, at least 60%, at least 70%, or at least 80%, so that the overall width of the protective tape is reduced to facilitate insertion or removal.

[0068] In addition, when the first leg 120 and the second leg 130 are inserted into the slot 310 and abut against the insertion opening 311 of the slot 310, the initial width d1 of the first gap G1 can remain substantially unchanged, that is, the width of the first gap G1 is just the same as the width in the fully released state or is slightly stressed and slightly different from the width in the fully released state. Figure 1 and Figure 3As shown, when the embedded portion abuts against the embedded opening 311 of the card slot 310, the width of the first gap G1 between the first leg 120 and the second leg 130 can be maintained at the initial width d1, that is, 0.2mm to 0.5mm, for the width of the embedded opening 311 is 1.2mm to 2.5mm. At this time, the clamping between the embedded portion and the card slot can be achieved by means of, for example, the limiting structure formed on the embedded portion described below, so as to maintain the support and protection of the embedded opening of the card slot. Alternatively, when the first leg 120 and the second leg 130 are embedded in the card slot 310 and abut against the embedded opening 311 of the card slot 310, under the action of the abutting force, the width of the first gap G1 is correspondingly reduced, for example, reduced to less than 0.5mm, optionally reduced to greater than or equal to 0mm, or greater than or equal to 0.1mm, so that the support and protection of the embedded opening of the card slot can be maintained by means of the restoring force of the first leg 120 and the second leg 130 tending to return to the initial state. Optionally, the width of the first gap G1 between the first leg 120 and the second leg 130 corresponding to the embedding opening 311 is less than or equal to 0.5 mm. Further optionally, the width of the first gap G1 corresponding to the embedding opening 311 is greater than or equal to 0 mm, or greater than or equal to 0.1 mm, and less than or equal to 0.5 mm. It should be understood that when the embedding portion is in contact with the embedding opening 311 of the card slot 310, depending on the configuration of the embedding opening 311, the width of the first gap G1 can be adaptively changed, thereby providing a convenient, fast and labor-saving embedding and removal operation, and ensuring the support and protection of the embedding opening. Similarly, the width of the second gap G2 can also be roughly consistent with the initial width d2 of the second gap in the fully released state, for example, 1 mm to 2 mm. Alternatively, the width of the second gap G2 is reduced, for example, reduced to less than or equal to 2 mm. Further optionally, the width of the second gap G2 is greater than or equal to 0.5 mm, or greater than or equal to 0.6 mm, and less than or equal to 2 mm.

[0069] In certain embodiments, the gap (including the first gap G1 and the additional second gap G2) can be configured to extend along at least most of the length of the embedded portion. In certain embodiments, the gap (including the first gap G1 and the additional second gap G2) can be configured as a single gap extending continuously along the length of the embedded portion or a plurality of gaps spaced apart. In certain embodiments, the gap (including the first gap G1 and the additional second gap G2) extends along the length of the embedded portion to one end of the embedded portion or extends to both ends of the embedded portion respectively. For further example, the gap (including the first gap G1 and the additional second gap G2) extends along the length of the embedded portion only to one end of the embedded portion or extends to both ends of the embedded portion respectively. Regardless of the configuration, the embedded portion with a gap effectively improves the process of embedding the embedded portion into and removing it from the card slot in a convenient and labor-saving manner.

[0070] It should be understood that the design of the embedded portion (including the first leg and the second leg) and the design of the gap (including the first gap G1 and the optional second gap G2) can take any shape as long as the gap provides structural deformation capability for the first leg and / or the second leg.

[0071] As described above, the embedding opening 311 of the card slot 310 in the card strip 300 is defined by, for example, a first convex rib 320 and a second convex rib 330 protruding toward each other, and the embedding portion of the protective strip 100 advantageously has a limiting structure adapted to the embedding opening of the card slot. Specifically, in the illustrated embodiment, the limiting structure is configured as a protrusion protruding from the first leg 120 and / or the second leg 130, for example, the first leg 120 is configured with a first protrusion 121 corresponding to the first convex rib 320, and the second leg 130 is configured with a second protrusion 131 corresponding to the second convex rib 330, and each protrusion has a limiting surface that matches the embedding opening of the card slot. For example Figure 1 and Figure 3 As shown, after the embedded portion is inserted into the card slot 310, the first protrusion 121 is suitable for being snapped to the top of the first rib 320 and has a first limiting surface 121a that can abut the first rib 320, and the second protrusion 131 is suitable for being snapped to the bottom of the second rib 330 and has a second limiting surface 131a that can abut the second rib 330. It should be understood that for the embedded openings of the card slots of different structural forms, the embedded portion of the protective belt may have one or more than two protrusions, or other forms of limiting structures (such as grooves, etc.). In addition, the limiting surface is a surface that may contact the structure at the embedded opening, which is used to further limit the embedded portion in the card slot 310 and further hold it, that is, the limiting surface can abut the structure at the embedded opening, and when the card slot 310 has a tendency to deform due to various reasons such as dimensional tolerance, improper placement or bumps during the transportation of the windshield, the card slot 310 can be prevented from deforming. In some cases, the limiting surfaces of each limiting structure are not necessarily in complete contact with the structure at the insertion opening (eg, the first convex rib 320 and the second convex rib 330 ), that is, the limiting surface may be in point contact, line contact, or surface contact with the structure at the insertion opening.

[0072] In some embodiments, the protective tape 100 and the clip strip 300 may be configured as a clip strip assembly, that is, Figure 3 In the state shown, the embedded portion of the protective tape 100 is embedded in the card slot 310. Afterwards, the card strip assembly can be attached to the windshield glass 500, as shown in FIG. Figure 5 Status shown.

[0073] exist Figure 2In the protective belt 200 of the illustrated embodiment, the structure of the embedded portion is similar to that of the above-mentioned protective belt 100, that is, the embedded portion has an embedded end 210 and is constructed to include a first leg 220 and a second leg 230 extending in the same direction from the embedded end 210, respectively, forming a gap (first gap G1) between the first leg 220 and the second leg 230, and the first leg 220 and / or the second leg 230 extending obliquely away from the distal end of the embedded end 210 to form an enlarged second gap G2 between the first leg 220 and the second leg 230. The first leg 220 is configured with a first protrusion 221 corresponding to the first rib 320, and the second leg 230 is configured with a second protrusion 231 corresponding to the second rib 330. After the embedded portion is inserted into the card slot, the first protrusion 221 is suitable for being snapped to the top of the first rib 320 and has a first limiting surface 221a that can abut against the first rib 320, and the second protrusion 231 is suitable for being snapped to the bottom of the second rib 330 and has a second limiting surface 231a that can abut against the second rib 330. In addition, in this embodiment, the protective belt 200 also includes a holding portion 240, which is configured to extend at an angle from the far end of the second leg 230 away from the embedded end 210 so as to be suitable for being held by an operator. The holding portion 240 can be used to apply a pulling force to the embedded portion (the first leg 220 and the second leg 230), so that the embedded portion and thus the protective belt 200 can be removed from the card slot 310 of the card strip more easily. Specifically combined with Figure 2 and Figure 4 In the illustrated embodiment, the grip portion 240 is configured to extend at an angle from the end of the second leg 230 opposite to the insertion end 210 so as to be suitable for an operator to hold. In some embodiments, the grip portion 240 may extend substantially perpendicularly relative to the second leg 230, for example, Figure 2 The second leg 230 shown has a distal end extending obliquely, and the proximal end of the second leg 230 near the embedding end 210 extends non-inclined relative to the main body of the embedding portion, so that the holding portion 240 can also be considered to extend substantially perpendicularly relative to the second leg 230. Advantageously, in this form of protective strip, the embedding portion and the holding portion are formed as an integrated protective strip to simplify production and reduce costs, for example, by appropriate processes such as extrusion molding or injection molding.

[0074] In this way, compared with the existing protective belt, the protective belt of the present disclosure provides a portion suitable for the operator to hold. When a force is applied to the holding portion, for example Figure 2In the illustrated manner, when a pulling force F is applied to the holding portion 240 as indicated by the arrow, the holding portion 240 drives the second leg portion 230 to rotate toward the first leg portion 220 while moving, thereby reducing the width of the first gap G1 and the second gap G2. In this state, the force F1 applied to the second leg portion 230 has two components in the vertical direction and the horizontal direction, wherein the horizontal component maintains the gap with a reduced width, and the vertical component moves upward, so that the embedded portion can be pulled out by applying only a small force without applying a large pulling force or using additional tools, further improving the efficiency of removing the protective tape from the card slot of the card strip.

[0075] In some embodiments, the holding portion 240 is configured to extend along at least most of the length of the second leg 230, that is, the operator can apply a pull-out force to at least most of the length of the second leg 230, which helps to achieve the above-mentioned application of a smaller and more balanced pull-out force. Preferably, the holding portion 240 extends along the entire length of the second leg 230. In some embodiments, the holding portion 240 is configured as a single section or a plurality of sections spaced apart that extend continuously along the length of the second leg 230. In some embodiments, the holding portion 240 extends along the length of the second leg 230 to one end of the second leg 230 or to both ends of the second leg 230 respectively. For further example, the holding portion 240 extends along the length of the second leg 230 only to one end of the second leg 230 or to both ends of the second leg 230 respectively. Regardless of the configuration, the protective tape of the present disclosure simplifies the removal action of the embedded portion in the card slot of the card strip through the holding portion.

[0076] To facilitate the operator's hand operation, such as Figure 2 As shown, the distance L1 that the grip portion 240 extends beyond the second leg portion 230 is advantageously set to be greater than or equal to 3.3 mm, greater than or equal to 3.5 mm, or greater than or equal to 3.7 mm. Figure 4 As shown, the distance L2 that the holding portion 240 extends beyond the outer edge of the clip strip 300 is advantageously greater than or equal to 3 mm. Considering factors such as the transportation and loading of the windshield in a vertically placed state on the carrier and the need for the packaging to avoid surrounding components, it is preferred to set the distance L2 that the holding portion 240 extends beyond the outer edge of the clip strip 300 to 3 mm to 5 mm. Correspondingly, the distance L1 that the holding portion 240 extends beyond the second leg 230 is 3.3 mm to 5.3 mm, 3.5 mm to 5.5 mm, or 3.7 mm to 5.7 mm. It should be understood that for different clip strip forms, the distance that the holding portion extends beyond the second leg or beyond the outer edge of the clip strip can be selected based on different needs.

[0077] Advantageously, the embedding portion (including the first leg 220 and the second leg 230) and the grip portion 240 are formed as an integral protective strip to simplify production and reduce costs.

[0078] Advantageously, for Figure 1 The protective tape 100 shown in FIG. 1 has a self-friction coefficient of 0.35 or less for the protective tape 100 or at least its embedded portion (the first leg 120 and the second leg 130). Figure 2 For the protective belt 200 shown, the self-friction coefficient of the protective belt 200 or at least the embedded part (the first leg 220 and the second leg 230) of the protective belt 200 is less than 0.35, for example, the self-friction coefficient is 0.1 to 0.3, and for example, the self-friction coefficient is 0.3, 0.2, 0.1. Here, the friction coefficient refers to the ratio of the friction force between the surfaces of two objects and the vertical force acting on one of their surfaces. The friction force is generated when two objects contact each other and slide relative to each other. The sliding friction coefficient is related to pressure and speed. The self-friction coefficient refers to the friction coefficient measured when the two objects are made of the same material. For example, in this article, the friction coefficient can be measured at a sliding speed of 0.42m / s and 200N. The inventors have found that the force required for the interaction of the protective belt when it is embedded in the card slot of the card strip is related to the friction coefficient of the contacted material. As the friction coefficient of the contacting material increases, the force required for interaction also increases.

[0079] The process of installing the protective belt 100 into the card strip 300 is simulated by using the finite element simulation software Abaqus 2022. Plane stress assumptions are made for the protective belt 100 (material, for example, polyhexamethylene adipamide) and the card strip 300, and cross-sections are taken for analysis. The protective belt 100 and the card strip 300 are meshed using CPS4. The mutual contact between the protective belt 100 and the card strip 300 uses a surface contact model in the simulation model. In this surface contact model, the tangential friction coefficient is changed to study the effect of the friction coefficient on the insertion force. Then a loading step is created. In this loading step, the displacement condition is used to control the protective belt 100 to be embedded in the card strip 300, and the reaction force during the embedding process is recorded. The materials used in the simulation model are shown in Table 1, where "elastic modulus" refers to the stress divided by the strain in the direction under uniaxial stress state, and "Poisson's ratio" refers to the ratio of the transverse normal strain to the axial normal strain when the material is under uniaxial tension or compression, which is an elastic constant reflecting the lateral deformation of the material.

[0080] Table 1

[0081] Material Parts Material Name Elastic modulus [MPa] Poisson's ratio Protection belt Polyhexamethylene adipamide (PA66) 3440 0.3

[0082] Through finite element numerical simulation, when the friction coefficient is reduced from 0.3 to 0.1, the force required for interaction is reduced from 27.3N to 14.1N, a decrease of 48.4%. By selecting extruded profiles or injection molded profiles, it is possible to provide a suitable and smaller force when the protective belt is embedded in the card slot of the card strip, thereby achieving a more convenient and labor-saving installation. At the same time, the use of materials with a small self-friction coefficient also ensures that the force required to remove the protective belt from the card slot is within a suitable and small range, making the removal process of the protective belt convenient and quick.

[0083] Alternatively, the protective belt can be integrally formed by selecting a suitable plastic (thermoplastic or thermosetting plastic) through, for example, an extrusion molding process. The materials that can be used include, but are not limited to, any one or any combination of polypropylene (PP), polyvinyl chloride (PVC), polyethylene (PE, such as PE330), and polyamide (PA). Advantageously, a polymer mixture with a lower friction coefficient (e.g., PA66 / UHWMPE) is a preferred material for reducing the pull-out force. For example, the friction coefficient of polyhexamethylene adipamide (PA66, commonly known as nylon-66) material is 0.3 to 0.4, the friction coefficient of ultra-high molecular weight polyethylene (UHWMPE, generally refers to unbranched linear polyethylene with a molecular weight of more than 1.5 million) material is 0.05 to 0.11, and the friction coefficient of polytetrafluoroethylene (PTEE) material is 0.045 to 0.08.

[0084] In some embodiments, the material of the protective tape 100, 200 or at least the embedded part of the protective tape 100, 200 includes a mixed material. According to different needs, in an optional embodiment, the mixed material includes a mixture of polyamide and ultra-high molecular weight polyethylene, or a mixture of polyamide and carbon fiber (carbon fiber, CF, usually refers to a high-strength high-modulus fiber with a carbon content of more than 90%), or a mixture of polyamide and polytetrafluoroethylene. The friction coefficient of carbon fiber is also relatively low, ranging from 0.1 to 0.5, and can also be used in appropriate occasions. The use of a mixed material can further reduce the friction coefficient, and, compared to, for example, using ultra-high molecular weight polyethylene or polytetrafluoroethylene with higher costs alone, a mixture of polyamide and ultra-high molecular weight polyethylene or polytetrafluoroethylene can obtain a lower friction coefficient in a cost-reducing manner. In addition, the use of a mixed material reduces the embedding force of the embedded part into the card slot and the pull-out force of removing it from the card slot, and can also take into account the considerations of the protection of the embedded part and the card slot itself during the embedding and removal process (such as the hardness, strength, wear resistance, etc. of the material).

[0085] In certain embodiments, when the mixed material includes a mixture of polyamide and ultra-high molecular weight polyethylene, the mixture of polyamide and ultra-high molecular weight polyethylene includes a mixture of polyhexamethylene adipamide and ultra-high molecular weight polyethylene.

[0086] In certain embodiments, when the mixed material includes a mixture of polyamide and ultra-high molecular weight polyethylene, the weight of the ultra-high molecular weight polyethylene accounts for 5% to 40% of the weight of the mixture, for example, the weight of the ultra-high molecular weight polyethylene accounts for 5%, 8%, 11%, 14%, 15%, 18%, 21%, 24%, 27%, 30%, 33%, 36%, 39% or 40% of the weight of the mixed material. Preferably, the weight of the ultra-high molecular weight polyethylene accounts for 10% to 20% of the weight of the mixture, for example, the weight of the ultra-high molecular weight polyethylene accounts for 10%, 13%, 15%, 16%, 19% or 20% of the weight of the mixed material. By selecting a suitable ratio of the weight of the ultra-high molecular weight polyethylene to the weight of the mixture, the protective tape 100, 200 or at least the embedded portion of the protective tape 100, 200 can have a smaller self-friction coefficient, so that only a smaller embedding force and extraction force are required to achieve the operation of embedding the embedded portion into the card slot and the operation of removing it from the card slot.

[0087] In certain embodiments, the mixed material further includes a compatibilizer. A compatibilizer, also known as a compatibilizer, refers to an auxiliary agent that promotes the combination of two incompatible polymers by means of intermolecular bonding forces to obtain a stable blend. Compatibilizers include, but are not limited to, polyethylene grafted with styrene (PE-g-ST), polypropylene grafted with styrene (PP-g-ST), acrylonitrile-butadiene-styrene copolymer grafted with maleic anhydrade (ABS-g-MAH), polyethylene grafted with maleic anhydrade (PE-g-MAH), polypropylene grafted with maleic anhydrade (PP-g-MAH), and high-density polyethylene grafted with maleic anhydrade (MAH-g-HDPE). Advantageously, the compatibilizer comprises maleic anhydride grafted high density polyethylene (MAH-g-HDPE). The molecular weight of the compatibilizer used in the present disclosure can be adjusted accordingly according to specific needs. The weight average molecular weight of the compatibilizer can be about 10,000-300,000, such as about 20,000-150,000 or about 20,000-120,000.

[0088] In certain embodiments, when the mixed material comprises a mixture of polyamide, ultra-high molecular weight polyethylene and a compatibilizer, the weight of the compatibilizer accounts for less than 2% of the weight of the mixture. In certain embodiments, the weight of the compatibilizer accounts for more than 0.9% of the weight of the mixture.

[0089] In certain embodiments, when the mixed material comprises a mixture of polyamide, ultra-high molecular weight polyethylene and a compatibilizer, the weight of the polyamide accounts for 84.6%-89.6% of the weight of the mixture, for example, 84.6%, 85.0%, 85.4%, 85.8%, 86.2%, 86.6%, 87.0%, 87.4%, 87.8%, 88.2%, 88.6%, 89.0%, 89.1%, 89.4% or 89.6%. In a specific embodiment, when the mixed material comprises a mixture of polyamide, ultra-high molecular weight polyethylene and a compatibilizer, the weight of the polyamide accounts for 89.1% of the weight of the mixture. In certain embodiments, when the mixed material comprises a mixture of polyamide, ultra-high molecular weight polyethylene and a compatibilizer, the weight of the ultra-high molecular weight polyethylene accounts for 9.4%-10.4% of the weight of the mixture, for example, 9.4%, 9.6%, 9.8%, 9.9%, 10.0%, 10.2% or 10.4%. In a specific embodiment, when the mixed material comprises a mixture of polyamide, ultra-high molecular weight polyethylene and a compatibilizer, the weight of the ultra-high molecular weight polyethylene accounts for 9.9% of the weight of the mixture. In certain embodiments, when the mixed material comprises a mixture of polyamide, ultra-high molecular weight polyethylene and a compatibilizer, the weight of the compatibilizer accounts for 0.94%-1.04% of the weight of the mixture, for example, 0.94%, 0.96%, 0.98%, 0.99%, 1.00%, 1.02% or 1.04%. In a specific embodiment, when the mixed material includes a mixture of polyamide, ultra-high molecular weight polyethylene and a compatibilizer, the weight of the compatibilizer accounts for 0.99% of the weight of the mixture.

[0090] In certain embodiments, when the mixed material includes a mixture of polyamide, ultra-high molecular weight polyethylene and a compatibilizer, the weight of the polyamide accounts for 84.6% to 89.6% of the weight of the mixture, for example, 84.6%, 85.0%, 85.4%, 85.8%, 86.2%, 86.6%, 87.0%, 87.4%, 87.8%, 88.2%, 88.6%, 89.0%, 89.1%, 89.4% or 89.6%, the weight of the ultra-high molecular weight polyethylene accounts for 9.4% to 10.4% of the weight of the mixture, for example, 9.4%, 9.6%, 9.8%, 9.9%, 10.0%, 10.2% or 10.4%, and the weight of the compatibilizer accounts for 0.94% to 1.04% of the weight of the mixture, for example, 0.94%, 0.96%, 0.98%, 0.99%, 1.00%, 1.02% or 1.04%.

[0091] In some embodiments, the mixed material includes a mixture of polyamide, ultra-high molecular weight polyethylene and a compatibilizer in a weight ratio of 90:10:1. By selecting the ratio of each component in the mixed material, the protective tape 100, 200 or at least the embedded portion of the protective tape 100, 200 can have a smaller self-friction coefficient, so that only a smaller embedding force and extraction force are required to achieve the operation of embedding the embedded portion into the card slot and the operation of removing it from the card slot.

[0092] In some embodiments, the self-friction coefficient of the contact portion of the card slot that contacts the embedded portion of the protective tape is less than 0.35, for example, the self-friction coefficient is 0.1 to 0.3, and for example, the self-friction coefficient is 0.3, 0.2, or 0.1. That is, the contact portion of the card slot that contacts the embedded portion can also have a smaller self-friction coefficient, thereby further making the embedding of the embedded portion more convenient and labor-saving, and the removal of the embedded portion more convenient and quick.

[0093] Figure 3 In the illustrated form of the card strip 300, in addition to the embedding opening 311 associated with the protective strip, the card slot 310 may also have some structures (usually made of elastomer or rubber material) that are in contact with or attached to the windshield and the matching parts, as well as reinforcing ribs (usually made of metal materials such as aluminum alloy) for increasing strength, etc. In some embodiments, relative to the protective strips 100 and 200, the material of the main body of the card slot 310 is the same as that of the protective strips 100 and 200 or at least the embedded portion of the protective strips 100 and 200; and / or the material of the embedding opening 311 of the card slot 310 is the same as that of the protective strips 100 and 200 or at least the embedded portion of the protective strips 100 and 200; and / or the material of the contact portion of the card slot 310 that contacts the embedded portion is the same as that of the protective strips 100 and 200 or at least the embedded portion of the protective strips 100 and 200. For example, the material of one or both of the first rib 320 and the second rib 330 protruding toward each other (or the contact portion of one or both of the first rib 320 and the second rib 330 and the embedded portion) constituting the embedded opening 311 of the card slot 310 may include any one or any combination of the materials described above. In this way, during the process of the embedded portion of the protective tape 100, 200 being embedded in the card slot 310 and removed from the card slot 310, since the embedded portion and the embedded opening 311 of the card slot 310 both include materials with a low self-friction coefficient, the operator only needs to apply a small force to easily implement the embedding operation and the removal operation, which is convenient and quick.

[0094] As can be seen from the above description, the protective belt of the present disclosure is constructed to include a first leg and a second leg with a gap formed therein, so that the operator can change the size of the gap by applying force to achieve the embedding of the embedding portion into the card slot of the card strip and remove it from the card slot with a small force, without applying a large extraction force or using additional tools. In a further optional manner, the protective belt provides a holding portion that the operator can hold, so that the removal of the embedding portion from the card slot of the card strip is easier to implement, and further combined with the material design of at least the embedding portion, it is ensured that the force required to remove the protective belt from the card slot is within a suitable and small range, so that the removal process of the protective belt is convenient and fast, and the removal efficiency of the protective belt is significantly improved. In addition, the material design of at least the embedding portion can also provide a suitable and small force during the embedding of the protective belt into the card slot of the card strip, thereby obtaining a more convenient and labor-saving installation. In addition, the protective belt of the present disclosure uses a limiting structure on the embedding portion that is compatible with the structure at the embedding port of the card slot, which ensures the effective limiting of the embedding portion at the embedding port of the card slot and provides a further holding effect, effectively providing stable protection and safety for the card slot of the card strip during transportation. The protective belt and clip assembly disclosed in the present invention has the advantages of simple structure, significant performance improvement and economical cost.

[0095] It should be understood here that the embodiments shown in the figures only show the optional shapes, sizes and arrangements of the protective band and the card strip assembly for the card strip according to the present disclosure, but they are only for illustration and not limitation. Other shapes, sizes and arrangements may also be adopted without departing from the concept and scope of the present disclosure.

[0096] The technical content and technical features of the present disclosure have been disclosed above. However, it can be understood that under the creative ideas of the present disclosure, technicians in this field can make various changes and improvements to the above disclosed concepts, but they all belong to the protection scope of the present disclosure. The description of the above implementation mode is illustrative rather than restrictive, and the protection scope of the present disclosure is determined by the claims.
