Description

Technical Field

[0001] This disclosure relates to the field of automotive manufacturing tooling technology, and in particular to a vehicle body internal clearance measuring device. Background Technology

[0002] Internal clearances within the vehicle body are critical dimensions in automobile manufacturing, directly impacting the vehicle's NVH (Noise, Vibration, and Harshness) performance. Failure to do so can lead to a series of problems that degrade the user experience, such as water leakage, increased operating force, and wind noise. Therefore, measuring or monitoring internal clearances is essential in current automobile manufacturing processes and problem analysis. However, due to structural limitations, conventional mechanical measuring instruments such as steel rulers, calipers, and feeler gauges are inadequate for measuring internal clearances. Current tools for measuring internal clearances include electronic internal clearance measuring instruments with computers and clay. However, electronic measuring instruments are expensive and require highly skilled operators, while clay measurement is inefficient and prone to significant errors. Summary of the Invention

[0044] Some embodiments of this disclosure will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. Various changes, modifications, and equivalents of the methods, apparatus, and / or systems described herein will become apparent upon understanding this disclosure. For example, the order of operations described herein is merely illustrative and is not limited to those orders set forth herein, but can be changed as will become apparent upon understanding this disclosure, except for operations that must be performed in a particular order. Furthermore, for clarity and brevity, descriptions of features known in the art may be omitted.

[0045] The embodiments described in the following examples of this disclosure are not representative of all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0046] See Figure 1 This illustration represents a structural schematic diagram of the vehicle body interior clearance measuring device 100 conforming to the principles of this disclosure in one state, specifically showing the state where the limiting pin 160 is positioned at the lower stop point of the first slide groove 131 (i.e., the end away from the second structure 220). In this exemplary embodiment, the vehicle body interior clearance measuring device 100 proposed in this disclosure is described as an example for measuring the interior clearance of a vehicle body. It will be readily understood by those skilled in the art that various modifications, additions, substitutions, deletions, or other changes may be made to the specific embodiments described below in order to apply the relevant designs of this disclosure to other types of application scenarios, and these changes are still within the scope of the principles of the vehicle body interior clearance measuring device 100 proposed in this disclosure.

[0047] like Figure 1 As shown, in one embodiment of this disclosure, the vehicle body internal gap measuring device 100 is used to measure the gap between a first structure 210 and a second structure 220 of the vehicle body. The first structure 210 can be, for example, the body body 110 (further, it can be a sheet metal stop or sheet metal cut edge of the body body 110), and the second structure 220 can be, for example, a door, hood, or rear cover. The vehicle body internal gap measuring device 100 includes a body 110 and a slider 130. (See also...) Figures 2 to 6 , Figure 2 The diagram shows a representative structural schematic of the vehicle body internal clearance measuring device 100 in another state, specifically showing the state in which the limiting pin 160 is limited to the upper stop point of the first slide groove 131 (i.e., the end near the second structure 220); Figure 3 The diagram shows a representative structural schematic of the vehicle body internal clearance measuring device 100 from another perspective; Figure 4 The image shows a representative side view of the vehicle body internal clearance measuring device 100; Figure 5 The figure shows a representative exploded three-dimensional view of the body interior clearance measuring device 100; Figure 6 The diagram above shows a representative illustration of the vehicle body interior clearance measuring device 100 in use. The structure, connection method, and functional relationship of the main components of the vehicle body interior clearance measuring device 100 disclosed herein will be described in detail below with reference to the aforementioned drawings.

[0048] like Figures 1 to 6As shown, in one embodiment of this disclosure, the main body 110 is provided with a magnet 120, which is used to attract the main body 110 to the first structure 210. A slider 130 is slidably disposed on the main body 110, and the sliding direction of the slider 130 is a first direction, which can be referred to as direction D1 shown in the accompanying drawings. One end of the slider 130 in the first direction (e.g., the upper end shown in the drawings) is a contact end, which is used to contact the second structure 220. The slider 130 is provided with a magnetic adsorption member 140, which is made of a magnetic metal, such as, but not limited to, iron. Alternatively, the slider 130 can be made of plastic or a non-magnetic metal to prevent the slider 130 from being magnetized by the magnet 120 and thus attracted and driven by the second structure 220. The magnetic adsorption member 140 is attracted by the magnet 120, allowing the slider 130 to be positioned relative to the main body 110 when it slides to any position. At least one of the main body 110 and the slider 130 is provided with a scale mark 151. Through the above structural design, this disclosure utilizes magnet 120 to fix the measuring device on the first structure 210 of the vehicle body, and simultaneously positions the slider 130. This ensures that the relative position of the slider 130 and the main body 110 is maintained when the slider 130 is pushed to any position by the second structure 220, facilitating the operator to obtain the internal clearance value through the scale markings 151. The vehicle body internal clearance measuring device 100 provided by this disclosure has a simple structure, low cost, and is easy to operate without needing a computer connection. It requires minimal operator skill, allows for direct visual reading, and has high measurement efficiency (e.g., less than 2 minutes per vehicle) while ensuring high measurement accuracy.

[0049] Specifically, compared to existing internal clearance measurement methods using clay, the vehicle body internal clearance measuring device 100 proposed in this disclosure significantly improves measurement accuracy, for example, reaching 0.2mm. Furthermore, compared to existing internal clearance measurement methods using electronic internal clearance measuring instruments, this disclosure eliminates the need for computer connection, reducing the technical requirements for operators and providing a measuring device with low manufacturing and operating costs, simple operation, and high measurement efficiency. Moreover, this disclosure employs a purely mechanical structure, making it robust, durable, and with a low failure rate. In addition, this disclosure is applicable to measuring internal clearances in various locations of vehicle bodies, such as doors, hoods, and rear covers. Its compact and convenient design allows for use anytime, anywhere, and has a wide range of applications.

[0050] like Figure 6As shown, taking the measurement of the inner gap at the rear cover of a vehicle using the vehicle body inner gap measuring device 100 disclosed herein as an example, specifically taking the first structure 210 as the vehicle body 110 and the second structure 220 as the rear cover, the measurement steps include: opening the vehicle rear cover, attaching the vehicle body inner gap measuring device 100 disclosed herein to the sheet metal cut edge of the rear cover, closing the rear cover, and then opening the rear cover again. The value of the inner gap at the rear cover can then be obtained by reading the scale marking 151 of the vehicle body inner gap measuring device 100. Similarly, when the second structure 220 is other structures such as a door or hood, a similar measurement procedure can be used.

[0051] like Figure 1 , Figure 2 and Figure 5 As shown, in one embodiment of this disclosure, the main body 110 may be provided with a through groove 111, which typically extends along a first direction. Based on this, the slider 130 can be slidably disposed in the through groove 111 of the main body 110. Through the above structural design, this disclosure utilizes the through groove 111 to achieve a sliding assembly between the main body 110 and the slider 130, resulting in a simple structure and reliable sliding function. In other embodiments of this disclosure, the main body 110 and the slider 130 may also adopt other structural forms to achieve a sliding assembly, such as providing guide rails or slides on the main body 110, and are not limited to this embodiment.

[0052] like Figure 1 , Figure 2 and Figure 5 As shown, based on the structural design of the main body 110 with a through groove 111, in one embodiment of this disclosure, the main body 110 may also be provided with a first through hole 112. This through hole extends along a second direction, which is perpendicular to the first direction, and the second direction can be referred to as direction D2 shown in the attached drawings. The two ends of the first through hole 112 are respectively located on the outer side of the main body 110 perpendicular to the second direction and on the groove wall of the through groove 111 perpendicular to the second direction. In other words, the first through hole 112 connects the through groove 111 and the outside of the main body 110 along the second direction. Based on this, a magnet 120 can be disposed in the first through hole 112 of the main body 110. Through the above structural design, this disclosure utilizes the first through hole 112 of the main body 110 to accommodate and arrange the magnet 120, facilitating the magnet 120's adsorption and positioning with the first structure 210 or the magnetic adsorption component 140. The structure is simple and the positioning is reliable. In other embodiments of this disclosure, the main body 110 may also be provided with other structures to arrange the magnet 120.

[0053] like Figure 1 and Figure 2As shown, in one embodiment of this disclosure, the vehicle body internal clearance measuring device 100 includes only one magnet 120, that is, the main body 110 is provided with only one magnet 120. This disclosure utilizes one magnet 120 to achieve adsorption and positioning with the first structure 210 or the magnetic adsorption component 140 respectively. Through the above structural design, this disclosure can reduce the number of parts, reduce the structural complexity of the measuring device, and reduce costs and manufacturing difficulties. In other embodiments of this disclosure, at least two magnets 120 may be provided on the main body 110, and the two magnets 120 may be used to achieve adsorption and positioning with the first structure 210 or the magnetic adsorption component 140 respectively, and this disclosure is not limited to this embodiment.

[0054] like Figure 1 and Figure 2 As shown, based on the structural design of the main body 110 with a through groove 111, in one embodiment of this disclosure, the slider 130 may have a first groove 131 on its side along a third direction. The first groove 131 extends along a first direction, which is perpendicular to the first direction, and the third direction can be referred to as direction D3 shown in the figure. Furthermore, the main body 110 may have a second through hole 113, which extends along a third direction, and its two ends are located on the outer side of the main body 110 perpendicular to the third direction and the groove wall of the through groove 111 perpendicular to the third direction, respectively. In other words, the second through hole 113 connects the through groove 111 and the outside of the main body 110 along the third direction. Based on this, the vehicle body internal clearance measuring device 100 proposed in this disclosure also includes a limiting pin 160. One end of the limiting pin 160 passes through the second through hole 113, and the other end extends into the first groove 131. The limiting pin 160 is used to limit the sliding position of the slider 130 toward the two ends of the main body 110 along the first direction, for example... Figure 1 The indicated "bottom dead center" position and Figure 2 The "top stop" position is shown. Through the above structural design, this disclosure can use the limiting pin 160 to limit the maximum sliding position of the slider 130 relative to the main body 110 along the first direction to both sides (e.g., the upper and lower sides shown in the figure), that is, to limit the sliding stroke of the slider 130 and prevent the slider 130 from dislodging from the through groove 111. During assembly, the slider 130 can be first inserted into the main body 110, so that the first groove 131 is exposed inside the second through hole 113, and then the limiting pin 160 is inserted to achieve assembly of the slider 130 and the main body 110.

[0055] Based on the structural design of the slider 130 having a first groove 131 and the main body 110 having a second through hole 113, in one embodiment of this disclosure, the slider 130 may have only one first groove 131, and the main body 110 may have only one second through hole 113, thereby simplifying the structural complexity and reducing the number of components (e.g., the limiting pin 160). In other embodiments of this disclosure, the slider 130 may also have multiple first grooves 131, and the main body 110 may also have multiple second through holes 113. For example, the slider 130 may have first grooves 131 on opposite sides along a third direction, and the main body 110 may have second through holes 113 on opposite sides along a third direction, and this is not limited to this embodiment.

[0056] like Figure 1 and Figure 2 As shown, in some other embodiments of this disclosure, when the main body 110 is provided with a first through hole 112 and a second through hole 113, the third direction and the second direction can intersect, or even be perpendicular, for example. Through the above structural design, this disclosure can arrange the first through hole 112 and the second through hole 113 on different intersecting sides of the main body 110, that is, arrange the magnetic adsorption member 140 and the first sliding groove 131 on different intersecting sides of the slider 130, thereby reducing structural complexity and processing difficulty. In some other embodiments of this disclosure, the third direction and the second direction can also be the same direction, that is, the second through hole 113 and the first through hole 112 can be located on the same side or opposite sides of the main body 110. Of course, since the embodiment shown in the figures also provides a second sliding groove 114 on the other side of the second direction of the main body 110 (that is, on one side of the fourth direction), the structural design of the second sliding groove 114, the first through hole 112, and the second through hole 113 being located on different sides of the main body 110 is realized.

[0057] like Figure 3 and Figure 5 As shown, based on the structural design of the main body 110 with a through groove 111, in one embodiment of this disclosure, the slider 130 may have a sliding part 132 provided on its side along a fourth direction. This fourth direction is perpendicular to the first direction, and the fourth direction may be, for example, direction D2 shown in the figure, that is, the fourth direction shown in the figure is the same as the second direction. Furthermore, the main body 110 may be provided with a second sliding groove 114 extending along the first direction, and the sliding part 132 slides in cooperation with the second sliding groove 114. Through the above structural design, this disclosure utilizes the sliding cooperation design of the sliding part 132 and the second sliding groove 114 to achieve the functions of limiting the slider 130 and guiding it during the sliding process.

[0058] like Figure 1 and Figure 3As shown, in some other embodiments of this disclosure, when the main body 110 is respectively provided with a first through hole 112 and a second sliding groove 114, the fourth direction and the second direction can be the same, and the first through hole 112 and the second sliding groove 114 are respectively located on opposite sides of the main body 110. Through the above structural design, this disclosure can arrange the first through hole 112 and the second sliding groove 114 on opposite sides of the intersecting main body 110, that is, arrange the magnetic adsorption member 140 and the sliding part 132 on opposite sides of the slider 130, thereby reducing structural complexity and processing difficulty. In some other embodiments of this disclosure, the first through hole 112 and the second sliding groove 114 can also be located on the same side of the main body 110 in the second direction (or the fourth direction), or the first through hole 112 and the second sliding groove 114 can also be located on two intersecting sides of the main body 110. Of course, since the embodiment shown in the figure also provides a second through hole 113 on a third-direction side of the main body 110, the structural design of the second through hole 113, the first through hole 112 and the second slide groove 114 being located on different sides of the main body 110 is realized.

[0059] like Figure 3 As shown, based on the structural design of slider 130 with sliding part 132 and main body 110 with second groove 114, in one embodiment of this disclosure, the second groove 114 can penetrate through groove 111 and outer side of main body 110 along the fourth direction (i.e., the second direction), so that sliding part 132 is exposed by the second groove 114. On this basis, the outer side of main body 110 can be provided with scale markings 151, and sliding part 132 can be provided with reference line markings 152. With the above structural design, the operator can directly read the measurement structure by the value of the specific mark of scale marking 151 currently corresponding to reference line marking 152. In other embodiments of this disclosure, scale markings 151 can also be provided on slider 130, for example, on the side of slider 130 perpendicular to the second direction or the side perpendicular to the third direction. In this case, the edge of main body 110 in the first direction (e.g., the top edge of main body 110 at through groove 111 shown in the figure) can be used as the reference line for reading the value. Furthermore, the main body 110 and the slider 130 may also be provided with scale markings 151. In addition, when the main body 110 is not provided with scale markings 151, or when the main body 110 is provided with scale markings 151 in a position other than that shown in this embodiment, the second slide groove 114 may also adopt a non-through design, that is, the second slide groove 114 is a groove 115 structure recessed into the groove wall of the through groove 111, which is not limited to this embodiment.

[0060] like Figure 3As shown, based on the structural design of slider 130 with sliding portion 132 and main body 110 with second groove 114, in one embodiment of this disclosure, one end of the second groove 114 along the first direction can open onto the surface of the main body 110, for example, the top end of the second groove 114 opens onto the top surface of the main body 110. Through the above structural design, during assembly, slider 130 can be inserted into the through groove 111 of the main body 110 from the side of the opening of the second groove 114, for example, from above the main body 110 downwards into the through groove 111. At this time, the opening of the second groove 114 allows the sliding portion 132 of slider 130 to enter, avoiding structural interference that could cause assembly difficulties. Furthermore, when slider 130 also has a contact portion 134 and the contact portion 134 extends beyond slider 130, the structural design of the opening of the second groove 114 facilitates the insertion of slider 130 into the through groove 111 of the main body 110, avoiding structural interference between the contact portion 134 and the main body 110.

[0061] like Figure 1 , Figure 2 and Figure 5 As shown, in one embodiment of this disclosure, the main body 110 may be provided with at least two of the magnets 120, such as, but not limited to, the two magnets 120 shown in the figures. These magnets 120 are arranged at intervals along a direction perpendicular to the first direction (e.g., direction D3 shown in the figures).

[0062] like Figure 5 As shown, in one embodiment of this disclosure, the surface of the slider 130 facing the magnet 120 (e.g., the surface of the slider 130 perpendicular to the second direction) may be provided with a mounting groove 133, and the magnetic adsorption member 140 may be accommodated in the mounting groove 133 of the slider 130. Specifically, taking the slider 130 as being made of copper and the magnetic adsorption member 140 as being made of iron, the magnetic adsorption member 140 may be embedded in the mounting groove 133 of the slider 130, thereby fixing the magnetic adsorption member 140 and the slider 130 together as one unit.

[0063] like Figure 1 , Figure 2 and Figure 6As shown, in one embodiment of this disclosure, a contact portion 134 may be provided at one end of the slider 130 along the first direction, and the surface of the contact portion 134 facing away from the main body 110 is an arc surface 1341, through which the contact portion 134 contacts the second structure 220. Through the above structural design, this disclosure utilizes the arc surface 1341 to achieve line contact between the slider 130 and the second structure 220. Since the second structure 220, such as the door, front cover, and rear cover, may have a relative angular deviation from the first structure 210 or the vehicle body internal gap measuring device 100 during the closing process, this disclosure utilizes a line contact form to reduce the impact of the above-mentioned angular deviation problem on the internal gap measurement results, and further improves the accuracy of the measurement.

[0064] like Figure 1 As shown, based on the structural design of the slider 130 with a contact portion 134, in one embodiment of this disclosure, the contact portion 134 can extend along a fifth direction and partially extend beyond the slider 130. This fifth direction is perpendicular to the first direction, and the fifth direction can be referenced to direction D2 shown in the accompanying drawings, that is, the fifth direction shown in the drawings can be the same as the second direction. Based on this, a groove 115 can be provided at one end of the main body 110 along the first direction. The groove 115 is used to accommodate a portion of the contact portion 134 and restricts the sliding position of the slider 130 toward the other end of the main body 110 along the first direction. Through the above structural design, this disclosure can utilize the groove 115 to accommodate a portion of the contact portion 134, thereby further reducing the minimum internal clearance that the vehicle body internal clearance measuring device 100 can measure, and achieving the limitation of the contact arm.

[0065] like Figure 1 As shown, based on the structural design of the slider 130 with a contact portion 134, in one embodiment of this disclosure, the fifth direction is the same as the second direction (i.e., the same as the fourth direction), and the contact portion 134 extends towards the same side as the first through hole 112. This avoids the second through groove 111 provided on the other side of the main body 110 in the second direction, further improving the structural rationality. In other embodiments of this disclosure, the contact portion 134 may also extend towards the same side as the second through groove 111, i.e., the contact portion 134 extends away from the first through hole 112. Alternatively, the fifth direction may be another direction perpendicular to the first direction and intersecting the second direction, such as direction D3 shown in the figure, and is not limited to this embodiment.

[0066] It should be noted that the vehicle body interior clearance measuring device 100 shown in the accompanying drawings and described in this specification is merely a few examples among many measuring devices capable of employing the principles of this disclosure. It should be clearly understood that the principles of this disclosure are by no means limited to any detail or component of the vehicle body interior clearance measuring device 100 shown in the accompanying drawings or described in this specification.

[0067] In summary, the vehicle body internal clearance measuring device 100 disclosed herein includes a main body 110 and a slider 130; the main body 110 is provided with a magnet 120, which is used to attract the main body 110 to the first structure 210; the slider 130 is slidably disposed on the main body 110, and the sliding direction is a first direction, one end of the slider 130 in the first direction is a contact end, which is used to contact the second structure 220; the slider 130 is provided with a magnetic adsorption member 140 made of magnetic metal, which is attracted by the magnet 120, so that the slider 130 is positioned relative to the main body 110 when it slides to any position; at least one of the main body 110 and the slider 130 is provided with a scale mark 151. Through the above structural design, this disclosure utilizes magnet 120 to fix the measuring device on the first structure 210 of the vehicle body, and simultaneously positions the slider 130. This ensures that the relative position of the slider 130 and the main body 110 is maintained when the slider 130 is pushed to any position by the second structure 220, facilitating the operator to obtain the internal clearance value through the scale marking 151. The vehicle body internal clearance measuring device 100 provided by this disclosure has a simple structure, low cost, is easy to operate without needing a computer connection, requires minimal operator skill, allows for direct visual reading, has high measurement efficiency, and ensures high measurement accuracy.

[0068] Furthermore, the term “exemplary” is used herein to mean serving as an example, instance, or illustration. Any aspect or design described herein as “exemplary” is not necessarily to be construed as advantageous compared to other aspects or designs. Rather, the use of the term “exemplary” is intended to present the concept in a concrete manner. As used herein, the term “or” is intended to mean an inclusive “or” rather than an exclusive “or.” That is, unless otherwise specified or clear from the context, “X applies A or B” is intended to mean any of the natural inclusive arrangements. That is, “X applies A or B” satisfies any of the foregoing instances if X applies A; X applies B; or both X applies A and B. Additionally, unless otherwise specified or clear from the context to refer to the singular form, the articles “a” and “an” as used in this application and the appended claims are generally understood to mean “one or more.”

[0069] Similarly, although this disclosure has been shown and described with respect to one or more implementations, equivalent variations and modifications will occur to those skilled in the art upon reading and understanding the specification and drawings. This disclosure includes all such modifications and variations and is limited only by the scope of the claims. In particular, with respect to the various functions performed by the components described above (e.g., elements, resources, etc.), unless otherwise indicated, the terminology used to describe such components is intended to correspond to any component (functionally equivalent) that performs the specific function of the described component, even if structurally not equivalent to the disclosed structure. Furthermore, although specific features of this disclosure may have been disclosed with respect to only one of several implementations, such features may be combined with one or more other features of other implementations, as may be desired and advantageous to any given or particular application. Moreover, with regard to the terms “comprising,” “owning,” “having,” “having,” or variations thereof as used in the detailed description or claims, such terms are intended to be inclusive in a manner similar to the term “including.”

[0070] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the invention disclosed herein. This application is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered exemplary only, and the true scope and spirit of this disclosure are indicated by the following claims.

[0071] It should be understood that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," "fixing," etc., used in the embodiments of this disclosure should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms herein according to the specific circumstances.

[0072] Although terms such as “first” and “second” may be used herein to describe various components, parts, regions, layers, or sections, these components, parts, regions, layers, or sections are not limited to these terms. Rather, these terms are used only to distinguish one component, part, region, layer, or section from another. Therefore, without departing from the teachings of the examples described herein, the first component, part, region, layer, or section mentioned in the examples may also be referred to as the second component, part, region, layer, or section. Furthermore, the terms “first” and “second” are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as “first” or “second” may explicitly or implicitly include at least one of that feature. In the description herein, “a plurality” means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0073] It should be understood that spatial relative terms, such as “above,” “upper,” “below,” and “lower,” are used herein to describe the relationship between one element and another shown in the figures. In addition to the orientation depicted in the figures, these spatial relative terms are also intended to encompass different orientations of the device in use or operation. For example, if the device in the figures is flipped, an element described as “above” or “upper” relative to another element would be “below” or “lower” relative to that other element. Thus, depending on the spatial orientation of the device, the term “above” encompasses both above and below orientations. Devices may have other orientations (e.g., rotated 90 degrees or in other orientations), and the spatial relative terms used herein should be interpreted accordingly.

[0074] It should be understood that this disclosure is not limited to the precise structures described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this disclosure is limited only by the appended claims.
