Anti-fall structure for bolt installation

Abstract

This application provides an anti-drop structure for bolt installation, including a barrier component, a snap-fit ​​component, and a disassembly component. The barrier component encloses an anti-drop operation space larger than the bolt. One end of the snap-fit ​​component is disposed on the barrier component, and the other end can snap onto the component to be snapped. The disassembly component is connected to the snap-fit ​​component and can at least drive the snap-fit ​​component to move away from the component to be snapped, so that the snap-fit ​​component is loosened from the component to be snapped. The anti-drop structure for bolt installation of this application is a detachable structure. When bolts need to be installed, they can be installed on the component to be snapped; when the nut is installed, it can be removed from the component to be snapped. This application does not follow the product off the production line. That is, compared with existing barrier structures that cannot be removed once installed on the product, this application does not increase the weight of the vehicle, which is beneficial for lightweight design, reusability, cost reduction, and improved heat dissipation of conductive parts.

Description

Technical Field

[0001] This application relates to the field of auxiliary tools in the assembly process of mechanical components, and more particularly to anti-drop structures for bolt installation. Background Technology

[0002] Currently, new energy electronic control products increasingly use bolts for interface connections. Compared to quick-connect solutions, this method offers higher vibration resistance, simpler structure, and significantly reduces interface design costs. However, bolt assembly often results in bolts falling off due to operational errors. For example, during fuse repair or IPT harness assembly, because the bolts are installed inside the product, they may accidentally fall off due to operational errors, ultimately causing product rework or even leaving bolts inside the product, leading to product failure.

[0003] Based on the above problems, the common practice is to add a barrier structure near the bolt to prevent it from falling off. This barrier structure is fixedly installed near the bolt and will accompany the entire life cycle of the car after installation. This barrier structure has the following technical problems: (1) It only prevents the bolt from falling off during assembly and connection, but since the barrier structure is always connected to the car, it will cause a waste of cost and materials; (2) When the bolt connection is near the high voltage and high current copper busbar, the high voltage and high current copper busbar will generate a lot of heat, and the setting of the barrier structure will be not conducive to the heat dissipation of the copper busbar, which will further deteriorate the environment near the copper busbar and even trigger insulation failure. Utility Model Content

[0004] The purpose of this application is to provide a bolt-mounting anti-drop structure, which is a detachable structure. When it is necessary to prevent bolts from falling off, it can be fixed to the bolt mounting position for protection. After the bolts are installed, it can be removed from the bolt mounting position and does not leave the production line. Therefore, the removed anti-drop structure can still be used for anti-drop installation in the same part of other vehicles, which means it can be reused and saves costs. In addition, since it is not carried by the whole vehicle, it will not interfere with the heat dissipation problem. Furthermore, it will not increase the weight of the whole vehicle.

[0005] This application provides an anti-drop structure for bolt installation, used to prevent bolts from falling off during the installation process; including:

[0006] The enclosure component provides a fall-prevention operating space with dimensions larger than the bolts;

[0007] A snap-fit ​​component, one end of which is disposed on the enclosure component and the other end of which can snap onto the component to be snapped, so that the enclosure component can be fixed at the bolt mounting position;

[0008] The disassembly component is connected to the snap-fit ​​component and is at least capable of driving the snap-fit ​​component to move in a direction away from the component to be snapped, so that the snap-fit ​​component is released from the component to be snapped.

[0009] In the above technical solution, the enclosure component further includes an enclosure cylinder;

[0010] The enclosure cylinder provides an anti-falling operating space with a size larger than that of the bolt.

[0011] In the above technical solution, the enclosure component further includes an abutment edge;

[0012] The abutting edge is disposed at one end of the enclosure cylinder along a first direction, and the abutting edge surrounds at least a portion of the circumferential edge of the enclosure cylinder.

[0013] In the above technical solution, the enclosure component further includes a reinforcing connecting plate;

[0014] One end of the reinforcing connecting plate is connected to the enclosure tube, and the other end is connected to the abutment edge;

[0015] Multiple reinforcing connecting plates are provided, and the multiple reinforcing connecting plates are arranged at intervals.

[0016] In the above technical solution, the snap-fit ​​component further includes a cantilever and a snap hook;

[0017] One end of the cantilever is disposed on the side wall of the enclosure cylinder, and the other end extends along the first direction and crosses the abutment edge in the first direction;

[0018] The hook is located at the end of the cantilever away from the enclosure cylinder, and a locking space is formed between the hook and the enclosure cylinder to lock onto the part to be locked.

[0019] In the above technical solution, the hook is further connected vertically to the cantilever, so that the hook has a straight end face facing the enclosure cylinder.

[0020] In the above technical solution, the snap-fit ​​component further includes a guide portion;

[0021] The guide portion is disposed at one end of the hook opposite to the cantilever, and the guide portion has a tapered structure along the first direction.

[0022] In the above technical solution, the side wall of the enclosure cylinder is further provided with an installation groove that extends along the first direction and penetrates the enclosure cylinder near the end of the component to be fastened.

[0023] The width of the cantilever is smaller than the width of the mounting groove. One end of the cantilever is connected to the top wall of the mounting groove, and the other end extends along the first direction.

[0024] In the above technical solution, the disassembly component further includes a connecting plate and a drive handle;

[0025] The connecting plate is set on the cantilever at a first preset position. One end of the drive handle is connected to the end of the connecting plate away from the cantilever, and the other end extends in a direction opposite to the first direction and passes over the end of the enclosure cylinder away from the abutment edge.

[0026] Driving the drive handle toward the enclosure cylinder can cause the hook to loosen from the component to be hooked.

[0027] In the above technical solution, the disassembly component further includes a fulcrum block;

[0028] The fulcrum block is set at a second preset position on the side wall of the enclosure cylinder and corresponds to the drive handle;

[0029] Driving the drive handle toward the enclosure cylinder, with the fulcrum block as the fulcrum, allows the hook to loosen from the component to be hooked.

[0034] The disassembly component is connected to the snap-fit ​​component and is at least capable of driving the snap-fit ​​component to move in a direction away from the component to be snapped, so that the snap-fit ​​component is released from the component to be snapped.

[0035] In summary, the anti-fall-off structure for bolt installation in this application is actually a detachable structure. When anti-fall-off protection is needed during nut installation, it can be installed near the nut; once the nut installation is complete, it can be detached from the mounting bracket. In other words, firstly, the anti-fall-off structure for bolt installation in this application does not follow the product off-line, meaning that compared to existing fencing structures that cannot be removed once installed, this application does not increase the vehicle's weight, thus contributing to lightweight vehicle design. Secondly, this detachable anti-fall-off structure for bolt installation can also be used for anti-fall-off protection in the same location on other vehicles, meaning it can be reused, reducing costs. Finally, because this structure can be detached from the mounting bracket, compared to existing fencing structures that can be removed once installed, this application does not interfere with heat dissipation at electrical connection points such as copper busbars.

Rather, the examples described herein are provided only to illustrate some of the many possible ways of implementing the methods, apparatus, and / or systems described herein that will be apparent upon understanding the disclosure of this application. Throughout this specification, when an element (such as a layer, region, or substrate) is described as being "on" another element, "connected to" another element, "bonded to" another element, "on" another element, or "covering" another element, it may be directly "on" another element, "connected to" another element, "bonded to" another element, "on" another element, or "covering" another element, or there may be one or more other elements in between.

[0051] To address the technical problems of increased costs and impaired heat dissipation of copper busbars caused by fixing a retaining structure near the bolts, this application provides a detachable anti-fall-off structure for bolt installation, which is described below in conjunction with... Figures 1-9 The structure will be explained in detail.

[0052] This anti-drop structure for bolt installation is used to prevent bolt 2 from falling off during the installation process. Specifically, as follows: Figure 1 and Figure 2 As shown, the anti-fall-off structure for bolt installation includes a retaining member 1, which has an anti-fall-off operating space 101 larger than that of the bolt 2. Combined with... Figure 5 , Figure 7 , Figure 8 and Figure 9 As shown, taking the connection of the wiring harness terminal 201 and the electrical control interface 202 using a copper busbar riveting nut 203 and bolt 2 as an example, after installing the enclosure component 1 near the pre-installation position of the bolt 2, the bolt 2 is tightened using a wrench; in the above process, since the enclosure component 1 encloses a space 101 larger than the nut's anti-falling operating space, it will not interfere with the tightening of the bolt 2. Furthermore, as... Figure 1 and Figure 2As shown, the anti-fall operation space 101 is cylindrical. The size of the anti-fall space is greater than the size of the nut, which means that the radial dimension of the anti-fall space is greater than the radial dimension of the nut. As a result, there will be a screwing operation gap between the enclosure component 1 and the nut in the radial direction, which provides convenience for screwing the bolt 2.

[0053] Specifically, the anti-fall-off structure for bolt installation also includes a snap-fit ​​component 3, the upper end of which is disposed on the enclosure component 1, and the lower end which can snap onto the component to be snapped (here, the component to be snapped is the electrical control interface 202); when the snap-fit ​​component 3 snaps onto the component to be snapped, since the component to be snapped is connected to the enclosure component 1, and since the bolt mounting position is formed on the wire harness terminal 201 located above the electrical control interface 202, the enclosure component 1 can be fixed at the bolt mounting position (the bolt mounting position refers to the vicinity of the pre-installation position of the bolt 2 mentioned above).

[0054] Specifically, the anti-fall-off structure for bolt installation also includes a disassembly component 4, which is connected to the locking component 3 and can drive the locking component 3 to move away from the part to be locked. Figure 5 , Figure 7 and Figure 9 In actual use, when it is necessary to install the enclosure component 1 at the bolt mounting position, the following steps are taken: Step 100: Place the overall structure of this application near the pre-installation position of the bolt 2; Step 200: Then use the disassembly component 4 to drive the snap-fit ​​component 3 to move in the direction away from the component to be snapped, which can be understood as the disassembly component 4 being able to drive the snap-fit ​​component 3 to be in the open state; Step 300: Then, press the enclosure component 1 vertically downward, so that the snap-fit ​​component 3 snaps onto the electrical control interface 202, thereby realizing the installation of the enclosure component 1; Step 400: Use a wrench to tighten the bolt 2 to the copper busbar. The wire harness terminal 201 and the electrical control interface 202 are connected together by the rivet nut 203 (the wire harness terminal 201 and the electrical control interface 202 have mounting holes at opposite positions, the copper busbar rivet nut 203 passes through the electrical control interface 202 and the wire harness terminal 201 in sequence, and the bolt 2 is screwed onto the copper busbar rivet nut 203 on the side of the wire harness terminal 201); Step 500: After the bolt 2 is screwed onto the copper busbar rivet nut 203, the disassembly component 4 is used again to drive the snap-fit ​​component 3 to move away from the component to be snapped, so that the snap-fit ​​component 3 is loosened from the electrical control interface 202, and finally the entire structure can be removed.

[0055] It is worth noting that: (1) Step 200 above can be simplified in actual use, that is, step 200 can be skipped and step 300 can be operated directly. (2) The structure of this application can be set with different models and different sizes according to different connection positions.

[0056] In summary, the anti-fall-off structure for bolt installation of this application is a detachable structure. When anti-fall-off protection is needed during bolt 2 installation, it can be placed near bolt 2 and snapped onto the mounting piece; when bolt 2 installation is complete, it can be detached from the mounting piece. That is to say, firstly, the anti-fall-off structure for bolt installation of this application does not follow... product Firstly, unlike existing fencing structures that can be removed once installed on a product, this application does not increase the product's weight, thus contributing to lightweight vehicle design. Secondly, this detachable anti-fall structure for bolt installation can also be used for anti-fall protection in the same location on other vehicles, meaning it is reusable, which reduces costs. Finally, because this structure can be detached from the mounting bracket, unlike existing fencing structures that can be removed once installed on a vehicle, this application does not interfere with heat dissipation at electrical connection points such as copper busbars, increasing the heat dissipation area of ​​the electronic control system under various operating conditions and improving heat dissipation efficiency, thereby improving the heat dissipation of conductive parts to a certain extent.

[0057] Furthermore, all of the aforementioned components are made of plastic. The plastic components, while still providing the anti-drop function for bolt 2, also reduce costs to some extent.

[0058] In this embodiment, the enclosure component 1 includes an enclosure cylinder 102, which encloses an anti-falling operating space 101 with a size larger than that of the bolt 2. Combined with... Figure 1 Optionally, if the enclosure cylinder 102 is cylindrical, then the anti-falling operating space 101 it encloses is also cylindrical.

[0059] Further integration Figure 1 As shown, the enclosure component 1 also includes an abutment edge 103; the abutment edge 103 is disposed at one end of the enclosure cylinder 102 along a first direction 104, where the first direction 104 refers to... Figure 1 The vertical downward direction in; such as Figure 1 The abutment edge 103 is located at the bottom edge of the enclosure cylinder 102.

[0060] Furthermore, the abutment edge 103 surrounds at least a portion of the circumferential edge of the enclosure cylinder 102. In actual design, depending on actual needs, the abutment edge 103 can be selected to surround the entire circumference of the enclosure cylinder 102, or it can be selected as... Figure 2 and Figure 3 As shown, the abutment edge 103 has two segments. These two segments are symmetrically arranged about the axis of the enclosure cylinder 102 and do not form a full circumference of the enclosure cylinder 102. A gap is formed between the two segments of the abutment edge 103, providing installation space for the locking member described below. In actual use, combined with... Figure 9As shown, the contact line 103 will eventually contact the harness terminal 201.

[0061] It is worth noting that: Figures 1-5 The previous illustration showed a structure where the abutment edge 103 is located on the outer side of the enclosure cylinder 102. However, this application not only includes the above-described arrangement, but also allows it to be located on the inner side of the enclosure cylinder 102 if the size of the anti-fall operating space 101 is large enough. Furthermore, the abutment edge 103 is set at a predetermined angle to the enclosure cylinder 102. Figures 1-5 As shown, the abutment edge 103 is perpendicularly connected to the enclosure cylinder 102. Of course, it is not limited to a perpendicular connection; in actual applications, a preset angle is set according to the surface structure of the component to be attached.

[0062] Further integration Figure 1 As shown, the enclosure component 1 also includes a reinforcing connecting plate 105; the reinforcing connecting plate 105 has a right-angled triangular structure, with one right-angled side connected to the enclosure cylinder 102 and the other right-angled side connected to the abutment edge 103. The reinforcing connecting plate 105 can improve the stability and firmness of the enclosure cylinder 102. Optionally, multiple reinforcing connecting plates 105 are provided, and the multiple reinforcing connecting plates 105 are spaced apart.

[0063] In this embodiment, combined with Figure 4 As shown, the snap-fit ​​component 3 includes a cantilever 301 and a hook 302; wherein, one end of the cantilever 301 is disposed on the side wall of the enclosure cylinder 102, and the other end extends along the first direction 104 and passes over the bottom of the enclosure cylinder 102 in the first direction 104, i.e. Figure 4 As shown, the bottom of the cantilever 301 is located below the enclosure cylinder 102. A hook 302 is disposed at the end of the cantilever 301 opposite to the enclosure cylinder 102, forming a locking space 303 between the cantilever 301 and the enclosure cylinder 102 for engaging the component to be engaged. Figure 5 As shown, the snap-fit ​​space 303 is exactly the sum of the thicknesses of the wire harness terminal 201 and the electrical control interface 202.

[0064] Furthermore, since one end of the cantilever 301 is located on the side wall of the enclosure cylinder 102 and the other end extends along the first direction 104, the abutment edge is preferably the two-section structure described above. That is, the cantilever 301 can pass through the gap formed between the two abutment edges and be located below the enclosure cylinder 102.

[0065] Further integration Figure 4 As shown, since the bottom surface of the electrical control interface 202 is flat, the hook 302 and the cantilever 301 are set to be vertically connected, so that the hook 302 has a flat end face 304 facing the enclosure cylinder 102. Therefore, when the hook 302 is engaged with the electrical control interface 202, it can fit against the bottom surface of the electrical control interface 202, making the engagement more effective.

[0066] Further integration Figure 4 As shown, the snap-fit ​​component 3 also includes a guide portion 305; the guide portion 305 is disposed at the end of the hook 302 away from the cantilever 301, and the guide portion 305 has a tapered structure along the first direction 104; specifically, the sidewalls facing each other of the two guide portions 305 are inclined sidewalls, and along the anti-fall structure... Figure 1 During the process of pressing down on the component to be secured in the first direction (vertically downward), since the guide part 305 is located below the hook 302, the guide part 305 will contact the component to be secured first. After the guide part 305 contacts the component to be secured, the side wall of the component to be secured and the guide part 305 will slide along the guide part 305, which has a tapered structure and an inclined side wall. Finally, the two guide parts 305 will slowly tighten and guide the hook 302 to engage with the component to be secured.

[0067] Further integration Figure 4 As shown, the side wall of the enclosure cylinder 102 has a mounting groove 106 extending along the first direction 104 and penetrating the enclosure cylinder 102 near the end of the component to be attached; the width of the cantilever 301 is smaller than the width of the mounting groove 106, one end of the cantilever 301 is connected to the top wall of the mounting groove 106, and the other end extends along the first direction 104 to the bottom of the enclosure cylinder 102. The width of the cantilever 301 is set smaller than the width of the mounting groove 106 so that the cantilever can rotate relative to the mounting groove, and the side wall of the mounting groove will not interfere with the cantilever.

[0068] In this embodiment, combined with Figure 5 As shown, the disassembly component 4 includes a connecting plate 401 and a drive handle 402; wherein, the connecting plate 401 is disposed at a first preset position on the cantilever 301, as shown. Figure 4 As shown, the first preset position refers to the position corresponding to the lower edge of the cantilever 301 and the enclosure cylinder 102. One end of the drive handle 402 is connected to the end of the connecting plate 401 away from the cantilever 301, and the other end extends in a direction opposite to the first direction 104 and passes over the enclosure cylinder 102 away from the abutment edge 103.

[0069] Optionally, two snap-fit ​​members 3 are provided symmetrically about the axis of the enclosure cylinder 102.

[0070] In summary, there are two methods in the actual installation process: (1) When it is necessary to install the enclosure component 1 at the bolt mounting position, first move the overall structure of this application to the position to be installed; then pinch the two drive handles 402 to move towards each other, so that the two hooks 302 move towards each other, that is, at this time the disassembly component 4 can drive the locking component 3 to be in the open state; then, press the enclosure component 1 in the vertical downward direction until the hook 302 is below the electrical control interface 202, release the drive of the two drive handles 402, so that the hook 302 is locked on the lower end face of the electrical control interface 202; then, use a wrench to screw the nut onto the copper busbar riveting nut 203, so that the wire harness terminal 201 and the electrical control interface 202 are connected together. After the nut is tightened onto the copper busbar riveting nut 203, squeeze the two drive handles 402 again to move them toward each other, so that the hook 302 is released from the electrical control interface 202, and then the whole structure can be removed.

[0071] It is worth noting that when the two drive handles 402 are pinched and moved toward each other, the top edge of the enclosure cylinder 102 will be used as the fulcrum (lever principle).

[0072] (2) When it is necessary to install the enclosure component 1 at the bolt mounting position, first move the overall structure of this application to the position to be installed; then press down the enclosure cylinder 102 directly. During the pressing process, the guide block will first contact the electrical control interface 202. Since the guide block has a tapered structure along the first direction 104, the guide block has a certain guiding effect on the hook 302; then a "click" sound will be heard, indicating that the hook 302 is locked onto the lower surface of the electrical control interface 202, thereby realizing the hook 302 is locked onto the lower end face of the electrical control interface 202; then, use a wrench to screw the nut onto the copper busbar riveting nut 203, thereby connecting the wire harness terminal 201 and the electrical control interface 202 together. After the nut is screwed onto the copper busbar riveting nut 203, squeeze the two drive handles 402 again to move them toward each other, so that the hook 302 is released from the electrical control interface 202, and then the overall structure can be removed.

[0073] Further integration Figure 4 As shown, the disassembly component 4 also includes a fulcrum block 403; the fulcrum block 403 is disposed at a second preset position on the side wall of the enclosure cylinder 102 and corresponds to the drive handle 402. The second preset position can be selected as the position of the enclosure cylinder 102 in the vertical direction.

[0074] In actual use, when the two drive handles 402 are squeezed and moved toward each other in opposite directions, the fulcrum block 403 can be used as a fulcrum, so that the hook 302 is loosened on the part to be hooked.

[0075] In this embodiment, combined with Figures 5-8 As shown, optionally, a guide groove 204 is provided at the position of the bolt mounting position corresponding to the electrical control interface 202; the guide groove 204 serves as a calibration function, that is, in the actual installation process, it is first necessary to ensure that the two snap-fit ​​components 3 correspond to the two guide grooves 204 respectively.

[0076] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
