Description
Technical Field
[0001] This application belongs to the field of automotive lighting, and particularly relates to a detachable nut clamp device and an automotive lighting. Background Technology
[0002] In the field of automotive lighting assembly, headlights are key components, and their assembly precision directly affects the vehicle's appearance quality and lighting performance. Traditional headlights are installed and fixed using integrated nut clamps. When the headlight mounting gap needs adjustment, the entire nut clamp must be disassembled for adjustment, which is cumbersome and can easily damage the mating holes. With the advancement of automotive manufacturing processes, the dimensional accuracy requirements for headlight gaps and surface differences are increasing, and traditional structures can no longer meet production demands.
[0003] Therefore, it is necessary to solve the above-mentioned technical problems. Utility Model Content
[0004] The purpose of this application is to provide a detachable nut clamp device and a vehicle lamp to solve the technical problem that it is not easy to adjust the installation gap of the vehicle lamp in the prior art.
[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: On one hand, a detachable nut clamp device is provided, comprising:
[0006] Lamp housing holder, used to connect the target lamp housing and form a through straight groove;
[0007] The mounting body, at least a portion of which is movably mounted in the straight groove and capable of entering or leaving the straight groove from both side ports, and the lamp housing base forming a limiting structure in a direction perpendicular to the straight groove to restrict the movement of the mounting body;
[0008] A locking mechanism is formed between the mounting body and the lamp housing holder and is used to lock the mounting body relative to the lamp housing holder or to allow the mounting body to move in the straight groove;
[0009] The nut clamp body is attached to the mounting body and forms a threaded hole for connecting the target bolt.
[0010] The beneficial effects of the detachable nut clamp device provided in this application are as follows: Compared with the prior art, in the detachable nut clamp device provided in this application, a straight groove is formed on the lamp housing base for connecting the target lamp housing. Since at least a part of the mounting body can enter the straight groove through the two side ports of the straight groove and move in the straight groove, and since a limiting structure for restricting the mounting body in the straight groove is formed on the lamp housing base and the locking mechanism can lock the position of the mounting body in the straight groove, after the target bolt passes through the vehicle body and is connected to the nut clamp through the screw hole, the lamp housing base can be moved or locked relative to the mounting body by adjusting the locking mechanism. In this way, the installation gap of the target vehicle lamp connected to the lamp housing base can be flexibly adjusted, which is far superior to the prior art.
[0011] Optionally, the straight groove is a dovetail groove with an open top; the portion of the mounting body used to fit into the dovetail groove is shaped to fit the dovetail groove and is slidably connected to the side wall of the dovetail groove. In this solution, by setting the straight groove as a dovetail groove with an open top, not only can the mounting body move more stably relative to the lamp housing base, but the side wall of the dovetail groove itself can also serve as a limiting structure to restrict the movement of the mounting body in the direction perpendicular to the straight groove. This allows the detachable nut clamp device in this application to achieve a more flexible gap adjustment effect.
[0012] Optionally, the portion of the mounting body used to fit into the dovetail groove forms a hollow groove parallel to the dovetail groove. In this design, by providing a hollow groove parallel to the dovetail groove on the mounting body, not only can the weight of the mounting body be effectively reduced, but the more easily deformable nature of the mounting body also allows it to move more smoothly within the dovetail groove. This enables the detachable nut clamp device in this application to achieve a more flexible gap adjustment effect.
[0013] Optionally, the portion of the mounting body located outside the dovetail groove forms a flat plate that abuts against the lamp housing holder; the nut clamp body is detachably clamped onto the flat plate and extends into the hollow groove. The flat plate has a through hole axially parallel to the depth direction of the dovetail groove, and the through hole and the screw hole are coaxially arranged. In this solution, by providing a flat plate on the mounting body for abutting against the lamp housing holder, a stable mounting position can be provided for the nut clamp body, and the mounting body can also provide a protective effect for the nut clamp body extending into the hollow groove. In this way, the mounting gap of the target vehicle lamp can be adjusted more stably and flexibly, which also helps to further improve the gap adjustment effect of the detachable nut clamp device in this application.
[0014] Optionally, the detachable nut clamp device further includes a sponge pad; the sponge pad has an elastic porous structure and is used to pad between the flat plate and the target vehicle body. In this application, by padding the flat plate and the target vehicle body with a sponge pad, a more stable relative positional relationship can be formed between the mounting body and the target vehicle body, which also allows the detachable nut clamp device in this application to achieve a more flexible gap adjustment effect.
[0015] Optionally, the sponge pad extends around the central axis of the through hole and forms a "U"-shaped structure. In this solution, by setting the sponge pad around the central axis of the through hole, a more stable relative positional relationship can be formed between the mounting body and the target vehicle body, which also allows the detachable nut clamp device in this application to achieve a more flexible gap adjustment effect.
[0016] Optionally, the locking mechanism includes a locking bolt and a through hole formed on the lamp housing; the through hole communicates with the straight groove and the axial direction of the through hole is perpendicular to the extension direction of the straight groove; the locking bolt is threaded into the through hole and is used to extend into the straight groove to abut against the mounting body. In this solution, by extending the locking bolt threaded into the through hole into the straight groove, the locking bolt can abut against the mounting body. Thus, the relative positional relationship between the mounting body and the lamp housing can be locked or the mounting body can be moved in the straight groove simply by tightening or loosening the locking bolt. This also allows the detachable nut clamp device in this application to achieve a more flexible gap adjustment effect.
[0017] Optionally, at least two sets of locking bolts and through holes are provided and spaced apart along the extension direction of the straight groove. In this solution, by providing at least two sets of locking bolts and through holes spaced apart along the extension direction of the straight groove, the relative positional relationship between the mounting body and the lamp housing can be locked more stably. This also allows the detachable nut clamp device in this application to achieve a more flexible gap adjustment effect.
[0018] Optionally, scales are correspondingly provided on the mounting body and the lamp housing, with the scales extending parallel to the straight groove. In this design, by correspondingly providing scales on the mounting body and the lamp housing, the relative position between the mounting body and the lamp housing can be adjusted more precisely, thus enabling the detachable nut clamp device in this application to achieve a more flexible gap adjustment effect.
[0019] On the other hand, this application also provides a vehicle light, including any of the detachable nut clamp devices as described above, and further including:
[0020] A fixing bolt is used to pass through the target vehicle body and be threaded into the bolt hole.
[0021] The beneficial effects of the vehicle lamp provided in this application are as follows: Compared with the prior art, in the vehicle lamp provided in this application, the fixing bolt can stably fix the mounting body to the target vehicle body by connecting with the screw hole on the nut clamp body. In addition, since the vehicle lamp in this application also includes any of the aforementioned detachable nut clamp devices, it also has the same technical effects as the aforementioned detachable nut clamp devices, which will not be elaborated here.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.
[0033] Please refer to the following: Figure 1 and Figure 2 The present application provides a detachable nut clamp device according to an embodiment. This detachable nut clamp device includes a lamp housing base 101, a mounting body 103, a locking mechanism, and a nut clamp body 104. Wherein:
[0034] The lamp housing holder 101 is used to connect to the target lamp housing and forms a through straight groove 102; at least a portion of the mounting body 103 is movably installed in the straight groove 102 and can enter or exit the straight groove 102 from both sides of the straight groove 102; the lamp housing holder 101 forms a limiting structure in a direction perpendicular to the straight groove 102 to restrict the movement of the mounting body 103; a locking mechanism is formed between the mounting body 103 and the lamp housing holder 101 and is used to lock the mounting body 103 relative to the lamp housing holder 101 or to allow the mounting body 103 to move in the straight groove 102; the nut clamp body 104 is connected to the mounting body 103 and forms a threaded hole for connecting the target bolt. It can be understood that in this embodiment, the nut clamp body 104 can be selected as a commonly used nut clamp structure in the art, which generally has a nut structure for installing the corresponding bolt, and will not be described in detail here.
[0035] According to the structure provided in this embodiment, in the detachable nut clamp device provided in this embodiment, a straight groove 102 is formed on the lamp housing seat 101 for connecting the target lamp housing. Since at least a part of the mounting body 103 can enter the straight groove 102 through the two side ports of the straight groove 102 and move in the straight groove 102, and since a limiting structure for restricting the mounting body 103 in the straight groove 102 is formed on the lamp housing seat 101 and the locking mechanism can lock the position of the mounting body 103 in the straight groove 102, after the target bolt passes through the vehicle body and is connected to the nut clamp through the screw hole, the lamp housing seat 101 can be moved or locked relative to the mounting body 103 by adjusting the locking mechanism. In this way, the installation gap of the target vehicle lamp connected to the lamp housing seat 101 can be flexibly adjusted, which is far superior to the prior art.
[0036] It is understood that the cross-sectional shape of the straight groove 102 in this embodiment is not limited, and can be selected as a rectangular groove or a T-shaped groove commonly used in the art, or can be flexibly set to other commonly used shapes. In addition, the locking mechanism, as a commonly used technical means in the art, can be set as a damping structure or a slot and buckle engagement structure commonly used in the art. For example, a slot or buckle structure can be provided on the mounting body 103, and a corresponding buckle or slot structure can be provided on the lamp housing base 101. In this way, after the mounting body 103 moves to the target position in the straight groove 102, the mounting body 103 can be locked relative to the lamp housing base 101 through the engagement structure of the slot and buckle.
[0037] It should also be noted that since the nut clamp is connected to the mounting body 103, if the nut clamp is damaged, the cost of using the detachable nut clamp device in this embodiment can be significantly reduced by replacing only the nut clamp and the mounting body 103 without replacing the lamp housing holder 101. Furthermore, since the lamp housing holder 101 can be flexibly replaced, the detachable nut clamp device in this embodiment can also be adapted to more lamp housing shapes, thus enabling a more flexible gap adjustment effect.
[0038] In another embodiment of this application, please refer to [the relevant document / reference]. Figure 1 and Figure 2 The straight groove 102 is a dovetail groove with an open top; the part of the mounting body 103 used to fit into the dovetail groove is formed to fit the shape of the dovetail groove and is slidably connected to the side wall of the dovetail groove.
[0039] According to the structure provided in this embodiment, by setting the straight groove 102 as a dovetail groove with an open top, not only can the mounting body 103 move more stably relative to the lamp housing 101, but the side wall of the dovetail groove itself can also serve as a limiting structure to restrict the movement of the mounting body 103 in the direction perpendicular to the straight groove 102. This allows the detachable nut clamp device in this embodiment to achieve a more flexible gap adjustment effect.
[0040] It is understood that the inclination angle, depth, and width of the dovetail groove in this embodiment can be adjusted according to actual load requirements. The fitting clearance between the mounting body 103 and the dovetail groove can balance smooth sliding and anti-shaking requirements. In addition, the part of the mounting body 103 that adapts to the dovetail groove can adopt a split slider design (such as metal base + engineering plastic bushing) to reduce the coefficient of friction. It should be noted that the open top structure of the dovetail groove facilitates quick assembly and disassembly of the mounting body 103, and at the same time, the mechanical limit is naturally formed by the inclined side wall, eliminating the need for additional limiting components and simplifying the overall structure.
[0041] In another embodiment of this application, please refer to [the relevant document / reference]. Figure 1 and Figure 2 The part of the mounting body 103 used to insert the dovetail groove forms a hollow groove 105 parallel to the dovetail groove.
[0042] According to the structure provided in this embodiment, by setting a hollow groove 105 parallel to the dovetail groove on the mounting body 103, the weight of the mounting body 103 can be effectively reduced. Furthermore, the mounting body 103 can move more smoothly in the dovetail groove due to its more easily deformable characteristics. This allows the detachable nut clamp device in this embodiment to achieve a more flexible gap adjustment effect.
[0043] It is understood that the arrangement of the hollowed-out grooves 105 (such as a single continuous groove or multiple intermittent grooves), their cross-sectional shape (such as rectangular, circular, or other geometric shapes), and whether they penetrate the sidewall of the mounting body 103 can all be adjusted according to actual needs. It should be noted that the weight-reducing design of the hollowed-out grooves 105 can reduce the frictional resistance of the mounting body 103 during sliding, while its local elastic deformation capacity can compensate for the machining tolerances of the dovetail grooves, ensuring smooth sliding. Furthermore, the presence of the hollowed-out area can also provide clearance space for the nut clamp body 104, avoiding motion interference.
[0044] In another embodiment of this application, please refer to [the relevant document / reference]. Figure 1 and Figure 2 The portion of the mounting body 103 located outside the dovetail groove forms a flat plate 106 that abuts against the lamp housing 101; the nut clamp body 104 is detachably clamped on the flat plate 106 and extends into the hollow groove 105. The flat plate 106 is provided with a through hole 107 axially parallel to the depth direction of the dovetail groove, and the through hole 107 and the screw hole are coaxially arranged.
[0045] According to the structure provided in this embodiment, by providing a flat plate portion 106 on the mounting body 103 for abutting against the lamp housing base 101, a stable mounting position can be provided for the nut clamp body 104. Furthermore, the mounting body 103 can also provide a protective effect for the nut clamp body 104 extending into the hollow groove 105. In this way, the mounting gap of the target vehicle lamp can be adjusted more stably and flexibly, which is also conducive to further improving the gap adjustment effect of the detachable nut clamp device in this embodiment.
[0046] It is understood that in this embodiment, the contact between the flat plate 106 and the lamp housing 101 can be achieved by planar contact or by adding positioning protrusions; the detachable clamping of the nut clamp body 104 and the flat plate 106 can be achieved by spring clips, screw fixing, or magnetic attraction; the coaxial arrangement of the through hole 107 and the screw hole allows the body bolts to pass directly through and precisely align with the nut clamp body 104. It should be noted that the extended design of the flat plate 106 not only protects the nut clamp body 104 in the hollow groove 105 from external impact, but also enables the mounting body 103 and the lamp housing 101 to form a more stable relative position. In addition, since the nut clamp body 104 and the mounting body 103 are also detachably connected in this embodiment, the cost of using the detachable nut clamp device in this embodiment can be further reduced.
[0047] In another embodiment of this application, please refer to [the relevant document / reference]. Figure 1 and Figure 2 The detachable nut clamp device also includes a sponge pad 108; the sponge pad 108 has an elastic porous structure and is used to pad between the flat plate 106 and the target body 1000.
[0048] According to the structure provided in this embodiment, by placing a sponge pad 108 between the flat plate 106 and the target vehicle body 1000, a more stable relative positional relationship can be formed between the mounting body 103 and the target vehicle body 1000. This also allows the detachable nut clamp device in this embodiment to achieve a more flexible gap adjustment effect.
[0049] It is understood that the material of the sponge pad 108 in this embodiment can be polyurethane foam, rubber foam, or other porous materials with elastic compression properties; its shape can be a square pad, an annular ring, or an irregular structure that matches the contour of the flat plate 106. It should be noted that the sponge pad 108 fills the microscopic uneven areas between the flat plate 106 and the body sheet metal through elastic deformation, eliminating assembly gaps, and at the same time suppressing relative displacement during vehicle movement through frictional resistance.
[0050] In another embodiment of this application, please refer to [the relevant document / reference]. Figure 1 and Figure 2 The sponge pad 108 extends around the central axis of the through hole 107 and forms a "U" shaped structure.
[0051] According to the structure provided in this embodiment, by setting the sponge pad 108 around the central axis of the through hole 107, a more stable relative positional relationship can be formed between the mounting body 103 and the target vehicle body 1000. This also allows the detachable nut clamp device in this embodiment to achieve a more flexible gap adjustment effect.
[0052] It is understood that in this embodiment, the opening direction (towards the vehicle body or lamp housing 101), side wall height (higher or lower than the surface of the flat plate 106), and arm width (symmetrical or asymmetrical) of the "U"-shaped sponge pad 108 can all be adjusted according to the assembly space. It should be noted that the "U"-shaped structure, through the design of surrounding the through hole 107, evenly distributes the clamping force when the vehicle body bolts are tightened, avoiding excessive local compression of the sponge pad 108; at the same time, its open side provides an operating channel for bolt installation tools, taking into account both stability and assembly convenience.
[0053] In another embodiment of this application, please refer to [the relevant document / reference]. Figure 1 and Figure 2 The locking mechanism includes a locking bolt 109 and a through hole 110 formed on the lamp housing 101. The through hole 110 communicates with the straight groove 102 and the axial direction of the through hole 110 is perpendicular to the extension direction of the straight groove 102. The locking bolt 109 is threaded into the through hole 110 and is used to extend into the straight groove 102 to abut against the mounting body 103.
[0054] According to the structure provided in this embodiment, by extending the locking bolt 109 threaded into the through hole 110 into the straight groove 102, the locking bolt 109 can abut against the mounting body 103. In this way, the relative positional relationship between the mounting body 103 and the lamp housing 101 can be locked or the mounting body 103 can be moved in the straight groove 102 simply by tightening or loosening the locking bolt 109. This also allows the detachable nut clamp device in this embodiment to achieve a more flexible gap adjustment effect.
[0055] It is understood that the head structure (such as internal hexagon, cross groove, or butterfly wing), thread specification (metric / imperial), and end shape (flat / tapered / spherical) of the locking bolt 109 in this embodiment can be selected according to operational requirements; the through hole 110 can be set as a smooth hole, a threaded hole, or a stepped hole. It should be noted that the locking bolt 109 achieves locking by generating friction through vertical pressure against the side of the mounting body 103, and the design of its axial vertical straight groove 102 decouples the operating direction from the adjustment movement direction, avoiding interference with the gap adjustment process.
[0056] In another embodiment of this application, please refer to [the relevant document / reference]. Figure 1 and Figure 2 At least two sets of locking bolts 109 and through holes 110 are provided and distributed at intervals along the extension direction of the straight groove 102.
[0057] According to the structure provided in this embodiment, by providing at least two sets of locking bolts 109 and through holes 110 at intervals along the extension direction of the straight groove 102, the relative positional relationship between the mounting body 103 and the lamp housing 101 can be locked more stably. This also allows the detachable nut clamp device in this embodiment to achieve a more flexible gap adjustment effect.
[0058] It is understood that in this embodiment, the number of locking bolt groups 109 (two or more groups), their distribution spacing (equidistant or unequal), and their arrangement (straight or staggered) can be adjusted according to the length of the straight groove 102. It should be noted that the synergistic effect of multiple locking bolt groups 109 can eliminate the risk of deflection of the mounting body 103 during long-stroke adjustment; the spaced distribution design ensures that the locking force is evenly transmitted to the contact surface between the mounting body 103 and the straight groove 102, avoiding deformation caused by localized stress concentration and ensuring reliable locking at any position throughout the entire stroke.
[0059] In another embodiment of this application, please refer to Figure 3 A scale 111 is provided on the mounting body 103 and the lamp housing 101 respectively, and the extension direction of the scale 111 is parallel to the straight groove 102.
[0060] According to the structure provided in this embodiment, by setting scales 111 on the mounting body 103 and the lamp housing 101 respectively, the relative position between the mounting body 103 and the lamp housing 101 can be adjusted more precisely, which also makes the detachable nut clamp device in this embodiment more flexible in terms of gap adjustment.
[0061] It is understood that the calibration method (such as laser engraving, printed label, or inlaid metal ruler), graduation value design (such as 1mm / 0.5mm), and reading reference (with the end face of the straight groove 102 as the zero point or a custom zero point) of the scale 111 in this embodiment can all be selected according to the accuracy requirements. It should be noted that the scale 111 directly displays the displacement of the mounting body 103 relative to the lamp housing 101, enabling the operator to quantitatively adjust the lamp gap; the extension direction of the parallel straight groove 102 ensures that the scale change is strictly synchronized with the movement trajectory of the mounting body 103, eliminating reading errors.
[0062] In another embodiment of this application, please refer to Figure 4 The invention also provides a vehicle light that includes a detachable nut clamp device as provided in any of the preceding embodiments, and a fixing bolt 112 for passing through a target vehicle body 1000 and being threaded into a screw hole.
[0063] According to the structure provided in this embodiment, in the vehicle lamp provided in this embodiment, the fixing bolt 112 can stably fix the mounting body 103 to the target vehicle body 1000 by connecting with the screw hole on the nut clamp body 104. In addition, since the vehicle lamp in this embodiment also includes any of the detachable nut clamp devices as described above, it also has the same technical effect as the aforementioned detachable nut clamp devices, and will not be described in detail here.
[0064] It is understood that the specifications (such as M6 / M8) and head structure (hexagonal head / flange face) of the fixing bolt 112 in this embodiment can be selected according to the thickness of the body sheet metal; its engagement with the screw hole of the nut clamp body 104 must meet the anti-loosening requirements (spring washers or thread sealant can be used), ensuring installation stability while inheriting the gap adjustment function of the detachable nut clamp device.
[0065] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
