Description

Technical Field

[0001] This application relates to the technical field of vehicle assembly, and more specifically, to a cutting bolt assembly. Background Technology

[0002] In current automotive electrical system assembly, the connection and tightening of the ground terminal is a critical step, directly affecting the safety and stability of the electrical system. Using ordinary bolts to tighten the ground terminal will not remove the electrophoretic paint from the nut, leading to poor electrical contact. Therefore, special cutting bolts are currently used to tighten the ground terminal.

[0003] In the assembly workshop, there are many types of bolts that look similar, which can easily cause confusion among employees during the assembly process, leading to assembly errors. These errors are difficult to detect on the assembly line in time, and potential electrical connection problems may only be exposed during the subsequent use of the vehicle, increasing the burden of after-sales service.

[0004] There is currently no good solution to the technical problem of easily using ordinary bolts for tightening during the grounding terminal fastening process. Utility Model Content

[0005] This application provides a cutting bolt assembly to at least solve the technical problem that ordinary bolts are easily mistakenly used for tightening in the grounding terminal fastening process.

[0006] According to one aspect of the embodiments of this application, a cutting bolt assembly is provided, comprising: a bolt body, the bolt body including a stud portion and a head; a ground terminal, the ground terminal having a first mounting structure, the ground terminal being sleeved on the stud portion through the first mounting structure, the ground terminal being disposed near the head; a locking member, the locking member having a second mounting structure, the locking member being sleeved on the stud portion through the second mounting structure, the ground terminal being located between the locking member and the head, the second mounting structure being adjustable in size to such that the locking member has a first state of preventing the ground terminal from detaching from the stud portion, and a second state of allowing the ground terminal to detach from the stud portion.

[0007] Furthermore, the stud portion includes: a first component section connected to the head; a second component section connected to the end of the first component section away from the head, the outer diameter of the second component section being larger than the outer diameter of the first component section, and the end of the second component section closer to the first component section forming a stepped surface; both the ground terminal and the locking member are sleeved on the first component section, and when the locking member is in the first state, part of the locking member abuts against the stepped surface.

[0008] Furthermore, the length of the first segment is less than the length of the second segment.

[0009] Furthermore, a cutting edge is provided on the outer wall of the end of the second section away from the first section.

[0010] Furthermore, the outer wall of the second section is provided with a chip removal groove, which extends along the length of the second section.

[0011] Furthermore, the locking element is a gasket, and the second mounting structure is a through hole formed in the middle of the gasket, with a notch in the circumferential direction of the through hole so that the diameter of the through hole can be adjusted.

[0012] Furthermore, the grounding terminal is provided with a positioning part, which is used to connect with the component to be fixed.

[0013] Furthermore, the positioning part is a flanged structure formed on the ground terminal.

[0014] Furthermore, the grounding terminal is provided with a connecting part for connecting to a wire to prevent the wire from detaching from the grounding terminal.

[0015] Furthermore, the connecting part is a connecting groove or connecting hole formed on the grounding terminal.

In the above solution, the cutting bolt assembly is used as a single unit, which is significantly different from ordinary bolts. During the tightening of the ground terminal, the use of ordinary bolts to tighten the ground terminal is avoided, thus preventing poor contact of the ground terminal. Attached Figure Description

[0034] Combination Figures 1 to 5 As shown, according to a specific embodiment of this application, a cutting bolt assembly is provided.

[0035] Specifically, the cutting bolt assembly includes: a bolt body 10, a ground terminal 20, and a locking member 30. The bolt body 10 includes a stud portion 11 and a head 12. The ground terminal 20 is provided with a first mounting structure 21, and the ground terminal 20 is sleeved on the stud portion 11 through the first mounting structure 21. The ground terminal 20 is located close to the head 12. The locking member 30 is provided with a second mounting structure 31, and the locking member 30 is sleeved on the stud portion 11 through the second mounting structure 31. The ground terminal 20 is located between the locking member 30 and the head 12. The second mounting structure 31 is adjustable in size so that the locking member 30 has a first state that prevents the ground terminal 20 from disengaging from the stud portion 11, and a second state that allows the ground terminal 20 to disengage from the stud portion 11.

[0036] In this embodiment, the cutting bolt assembly includes a bolt body 10, a ground terminal 20, and a locking member 30. Both the locking member 30 and the ground terminal 20 are sleeved on the stud portion 11. The ground terminal 20 is located between the head 12 of the bolt body 10 and the locking member 30. By adjusting the dimensions of the second mounting structure 31 of the locking member 30, the ground terminal 20 can be disassembled, assembled, and locked. In the above solution, the cutting bolt assembly is used as a single unit, which is significantly different from ordinary bolts. During the tightening of the ground terminal 20, the use of ordinary bolts to tighten the ground terminal 20 is avoided, thus preventing poor contact of the ground terminal 20.

[0037] It should be noted that the stud portion 11 is provided with a cutting edge 1122 to remove the electrophoretic paint from the nut.

[0038] In one exemplary embodiment of this application, the stud portion 11 includes a first component segment 111 and a second component segment 112. The first component segment 111 is connected to the head 12, and the second component segment 112 is connected to the end of the first component segment 111 away from the head 12. The outer diameter of the second component segment 112 is larger than the outer diameter of the first component segment 111, and the end of the second component segment 112 near the first component segment 111 forms a stepped surface 1121. The ground terminal 20 and the locking member 30 are both sleeved on the first component segment 111. When the locking member 30 is in a first state, a portion of the locking member 30 abuts against the stepped surface 1121.

[0039] In the embodiments of this application, the stud portion 11 has a stepped structure. The stepped surface 1121 of the stepped structure forms a limiting space between the head 12 of the bolt body 10. When the locking member 30 is locked with the stud portion 11, the locking member 30 abuts against the stepped surface 1121. The stepped surface 1121 is used to axially limit the locking member 30 to prevent the locking member 30 from moving axially relative to the stud portion 11, thereby ensuring a stable connection between the ground terminal 20 and the bolt body 10.

[0040] like Figure 1 , Figure 2 As shown, the stud portion 11 includes a first component segment 111 and a second component segment 112. The first component segment 111 is connected to the head 12. The outer diameter of the second component segment 112 is larger than the outer diameter of the first component segment 111, so that the stud portion 11 has a stepped structure. A stepped surface 1121 is formed at the junction of the first component segment 111 and the second component segment 112, and a limiting space is formed between the stepped surface 1121 and the head 12. The first mounting structure 21 on the ground terminal 20 is a connection through hole formed in the ground terminal 20, and the ground terminal 20 is sleeved on the first component segment 111 through the connection through hole. The second mounting structure 31 on the locking member 30 is a through hole. The locking member 30 is sleeved on the first component section 111 through the through hole. By reducing the size of the through hole, the locking member 30 abuts against the stepped surface 1121 to confine the ground terminal 20 within the limiting space. By increasing the size of the through hole, the locking member 30 can be separated from the stepped surface 1121 to realize the removal of the ground terminal 20 and the locking member 30.

[0041] In one exemplary embodiment of this application, the length of the first component segment 111 is less than the length of the second component segment 112.

[0042] In the embodiments of this application, the length of the first component segment 111 is less than the length of the second component segment 112, so as to reduce the limiting space between the stepped surface 1121 and the head 12 and avoid severe shaking of the locking member 30 and the ground terminal 20 within the limiting space. In addition, the total length of the stud portion 11 is a fixed value. Shortening the length of the first component segment 111 is equivalent to increasing the length of the second component segment 112, thereby increasing the effective length of the connection between the stud portion 11 and the nut and improving the connection strength.

[0043] In one exemplary embodiment of this application, a cutting edge 1122 is provided on the outer wall of the end of the second component segment 112 that is away from the first component segment 111.

[0044] In the embodiments of this application, the cutting edge 1122 is located at the end of the second component segment 112 that is away from the first component segment 111. When the second component segment 112 is connected to the nut, it can more thoroughly remove the electrophoretic paint inside the nut, further reducing the phenomenon of poor contact of the ground terminal 20.

[0045] like Figure 2 As shown, the cutting edge is located on the outer wall of the second component section 112, and the cutting edge is located away from the first component section 111 to maximize the cutting length of the nut, that is, to more thoroughly remove the electrophoretic paint inside the nut, so that the stud part 11 and the nut can be effectively electrically connected, and further so that the ground terminal 20 and the nut can be effectively electrically connected, reducing the phenomenon of poor contact of the ground terminal 20.

[0046] In one exemplary embodiment of this application, a chip removal groove 1123 is provided on the outer wall of the second component segment 112, and the chip removal groove 1123 extends along the length direction of the second component segment 112.

[0047] In the embodiments of this application, the chip removal groove 1123 is provided so that the removed electrophoretic paint can be discharged through the chip removal groove 1123, reducing the feeding resistance of the stud part 11, and enabling the stud part 11 to smoothly enter the threaded hole of the nut and connect with the nut threadedly.

[0048] The chip removal groove 1123 can be a straight groove or a spiral groove.

[0049] For example, such as Figure 2 As shown, the chip removal groove 1123 on the outer wall of the second section 112 is a straight groove.

[0050] In one exemplary embodiment of this application, such as Figure 4 As shown, the locking member 30 is a gasket, and the second mounting structure 31 is a through hole formed in the middle of the gasket. The through hole has a notch 32 in the circumferential direction so that the diameter of the through hole can be adjusted.

[0051] In the embodiments of this application, the size of the through hole is changed by adjusting the size of the notch 32, thereby realizing the locking and unlocking of the locking member 30 and the stud portion 11.

[0052] In one exemplary embodiment of this application, the ground terminal 20 is provided with a positioning part 22, which is used to connect with the component to be fixed.

[0053] In this application, the ground terminal 20 can cooperate with the component to be fixed through the positioning part 22 to limit the position of the ground terminal 20 and prevent the ground terminal 20 from rotating relative to the component to be fixed.

[0054] like Figure 3 As shown, the positioning part 22 is a flange structure formed on the ground terminal 20.

[0055] like Figure 5 As shown, the cutting bolt assembly is used in vehicle assembly and is connected to the body sheet 40, on which a nut is formed. The second section 112 of the stud portion 11 is threadedly connected to the nut on the body sheet 40, so that the body sheet 40 abuts against the locking member 30. The body sheet 40 is provided with a positioning hole, into which the positioning portion 22 of the ground terminal 20 is inserted to prevent the ground terminal 20 from rotating relative to the body sheet 40.

[0056] In one exemplary embodiment of this application, the ground terminal 20 is provided with a connecting portion 23, which is used to connect with a wire to prevent the wire from detaching from the ground terminal 20.

[0057] In the embodiments of this application, the connection part 23 strengthens the physical contact between the wire and the ground terminal 20, ensuring a stable electrical connection.

[0058] Preferably, the connecting portion 23 is a connecting groove or connecting hole formed on the ground terminal 20. The connecting groove or connecting hole formed on the ground terminal 20 can provide a precise positioning point for the wire, ensuring that the wire can accurately make contact with the ground terminal 20 when crimped or inserted.

[0059] like Figure 3 As shown, the connecting part 23 is a U-shaped connecting groove formed on the ground terminal 20.

[0060] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0061] In addition to the above, it should be noted that the terms "one embodiment," "another embodiment," and "embodiment" used in this specification refer to specific features, structures, or characteristics described in connection with that embodiment, which are included in at least one embodiment described in the general description of this application. The appearance of the same expression in multiple places in the specification does not necessarily refer to the same embodiment. Furthermore, when a specific feature, structure, or characteristic is described in connection with any embodiment, the intention is to suggest that implementing such a feature, structure, or characteristic in conjunction with other embodiments also falls within the scope of this utility model.

[0062] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

[0063] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
