Description

Technical Field

[0001] This utility model relates to the field of automotive parts application technology, and in particular to a lamp frame positioning structure for automotive headlights. Background Technology

[0002] As a core lighting component for vehicles driving at night and in low-visibility environments, the stability of the headlight frame positioning structure directly affects the accuracy of the lighting angle and its service life. The headlight frame positioning structure must simultaneously ensure the secure fixation of the lamp body and facilitate heat dissipation. It must prevent the headlight frame from shifting or making abnormal noises due to vibrations during vehicle operation, while also meeting the heat dissipation requirements of the lamp body to prevent heat accumulation from affecting lighting performance and accelerating component aging. It is a key component in ensuring the overall function of the headlight.

[0003] Existing automotive headlight frame positioning structures mostly use bolts to directly connect the frame to the vehicle body. This method requires tightening multiple bolts one by one, making the installation process cumbersome and time-consuming. Furthermore, subsequent maintenance and disassembly require repetitive operations, resulting in poor convenience. Moreover, during long-term use, the continuous vibrations generated by vehicle movement can easily cause the bolts to loosen, leading to frame misalignment, affecting the illumination angle, and even causing component collision noises. Therefore, this utility model proposes a new headlight frame positioning structure. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a lamp frame positioning structure for automotive headlights, so as to simplify the installation process, improve positioning stability, and simultaneously achieve efficient heat dissipation of the lamp body, thereby solving the problems of cumbersome installation, easy loosening and insufficient heat dissipation of existing structures.

[0005] To solve the above-mentioned technical problems, the present invention provides a lamp frame positioning structure for an automotive headlight, including a lamp body, wherein a heat sink is connected to the end face of the lamp body to dissipate the heat generated by the lamp body.

[0006] The end face of the radiator facing the lamp body is engaged with a connecting frame, and the connecting frame is engaged with a mounting frame, so that the headlight is fixed to the mounting frame that is pre-bolted to the car through the connecting frame.

[0007] The present invention is further configured such that: one end of the lamp body is provided with a conductive terminal, and the conductive terminal is located inside the heat sink and is electrically connected to an external power source.

[0008] By incorporating the conductive terminals into the heat sink, the structure of the heat sink provides physical protection for the conductive terminals, preventing poor contact caused by external dust and moisture. Furthermore, the heat sink can simultaneously cool the conductive terminals during the heat dissipation process, preventing them from aging due to prolonged power-on heating and ensuring the stability of the headlight power supply.

[0009] The present invention is further configured such that: the mounting frame includes a collar, and the collar is sleeved on the outer wall of the lamp body, and is tightly fitted to the sealing ring sleeved on the outer wall of the lamp body; the outer circumferential wall of the collar is uniformly fixedly connected with a plurality of alternately distributed mounting lugs and connecting lugs.

[0010] Through the above technical solution, the tight fit design of the collar and the sealing ring can form a sealing structure between the lamp body and the mounting frame, preventing external rainwater and dust from entering the lamp body and protecting the core components of the lamp body; while the alternating mounting lugs and connecting lugs not only realize the stable bolt connection between the mounting frame and the car through the mounting lugs, but also provide precise connection points for the connecting frame through the connecting lugs, ensuring the overall structure is stress-balanced.

[0011] The present invention is further configured such that: an extension sleeve is fixedly connected to the bottom of each of the plurality of connecting ear blocks, and a compression crossbar is fixedly connected to the middle of each of the plurality of extension sleeves.

[0012] Through the above technical solution, the extension sleeve can extend the connection length of the connecting lug, providing sufficient insertion space for the positioning post of the connecting frame to ensure the connection depth; while the extrusion crossbar, as a key extrusion component, can cooperate with the extrusion groove when the positioning post is inserted, and deform the positioning post and press it against the inner wall of the extension sleeve through mechanical extrusion, so as to achieve an interference fit between the connecting frame and the mounting frame and improve the positioning firmness.

[0013] The present invention is further configured such that: the connecting frame includes a positioning ring, a plurality of connecting fan blocks are uniformly fixedly connected to the outer circumferential wall of the positioning ring, a locking block is fixedly connected to the bottom of each of the plurality of connecting fan blocks and the locking block is locked to the heat sink, a positioning post is fixedly connected to the top of each of the plurality of connecting fan blocks, and the plurality of positioning posts respectively penetrate the extension sleeve.

[0014] Through the above technical solutions, the positioning ring can provide unified support for the connecting fan blocks, ensuring the coaxiality of multiple connecting fan blocks and ensuring that the positioning post can be accurately aligned with the extension sleeve; the snap-fit ​​block and the heat sink are snap-fitted together, enabling the quick assembly of the connecting frame and the heat sink; and the design of the positioning post penetrating through the extension sleeve builds a connecting bridge between the connecting frame and the mounting frame. Through the snap-fit ​​and penetrating dual connection methods, both installation efficiency and structural stability are taken into account.

[0015] The present invention is further configured such that: one end of the locking block is fixedly connected to a spring piece, and the spring piece abuts against the inner wall of the slot opened on the end face of the heat sink; at the same time, a limiting block is provided at the other end, and the limiting block is inserted into the inside of the slot.

[0016] Through the above technical solution, the insertion of the limiting block into the slot can achieve the initial positioning of the locking block in the slot, preventing the locking block from sliding along the length of the slot; while the elastic pressing effect of the spring can eliminate the gap between the locking block and the slot, avoid abnormal noise caused by vibration during vehicle operation, and at the same time enhance the tightness of the locking connection, preventing the locking block from falling out of the slot.

[0017] The present invention is further configured such that: a V-shaped extrusion groove is provided inside the positioning post, and the extrusion crossbar makes the two sides of the positioning post abut against the inner wall of the extension sleeve through the extrusion groove; at the same time, a locking block is fixedly connected to the end face of the positioning post, and the positioning post and the connecting lug are limited and fixed by the locking block.

[0018] Through the above technical solution, the V-shaped extrusion groove can evenly distribute the extrusion force to both sides of the positioning post when the extrusion crossbar is inserted, so that the two sides of the positioning post expand outward and tightly abut against the inner wall of the extension sleeve, forming a reliable frictional fixation; while the locking block can engage with the end face of the connecting ear block after the positioning post is fully inserted, restricting the positioning post from being pulled out axially, achieving a dual fixing effect of "radial abutment and axial limit", further improving the anti-loosening ability of the positioning structure.

[0019] The beneficial effects of this utility model are as follows:

[0020] 1. The lamp frame positioning structure of the automotive headlight proposed in this utility model adopts a layered snap-fit ​​connection design to replace the traditional multi-point bolt fixing method, which simplifies the installation steps. At the same time, it uses spring pieces, extrusion grooves, and locking blocks to achieve multiple fixing, effectively solving the problem of easy loosening of traditional structures and improving positioning stability.

[0021] 2. The lamp frame positioning structure of the automotive headlight proposed in this utility model directly connects the heat sink to the end face of the lamp body, so that the heat generated by the lamp body can be quickly transferred to the heat sink and dissipated. At the same time, the conductive terminals are built into the heat sink, and the heat sink cools the conductive terminals simultaneously, which ensures the lighting stability and service life of the headlight, and takes into account both heat dissipation function and structural practicality.

[0029] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0030] like Figures 1-3 As shown, a lamp frame positioning structure for an automotive headlight includes a lamp body 1. A heat sink 2 is connected to the end face of the lamp body 1 to dissipate the heat generated by the lamp body 1. A conductive terminal 11 is provided at one end of the lamp body 1, and the conductive terminal 11 is located inside the heat sink 2 and is electrically connected to an external power source. By embedding the conductive terminal 11 inside the heat sink 2, the structure of the heat sink 2 can provide physical protection for the conductive terminal 11, preventing external dust and moisture from corroding and causing poor contact. On the other hand, the heat sink 2 can simultaneously cool the conductive terminal 11 during the heat dissipation process, preventing it from aging due to long-term power supply and ensuring the stability of the headlight power supply.

[0031] like Figures 4-6 As shown, the end face of the radiator 2 facing the lamp body 1 is connected to a connecting frame 4. The connecting frame 4 includes a positioning ring 41. Multiple connecting fan blocks 42 are uniformly fixedly connected to the outer circumferential wall of the positioning ring 41. The positioning ring 41 can provide uniform support for the connecting fan blocks 42, ensuring the coaxiality of the multiple connecting fan blocks 42 and ensuring that the positioning post 44 can be accurately aligned with the extension sleeve 34.

[0032] Each of the multiple connecting fan blocks 42 has a locking block 43 fixedly connected to its bottom, and the locking block 43 is locked to the radiator 2. The locking connection between the locking block 43 and the radiator 2 enables the quick assembly of the connecting frame 4 and the radiator 2. One end of the locking block 43 is fixedly connected to a spring piece 431, and the spring piece 431 presses against the inner wall of the slot 21 opened on the end face of the radiator 2. The elastic pressing action of the spring piece 431 can eliminate the gap between the locking block 43 and the slot 21, avoid abnormal noise caused by vibration during the car's operation, and enhance the tightness of the locking connection to prevent the locking block 43 from falling out of the slot 21. At the same time, a limiting block 432 is provided at the other end, and the limiting block 432 is inserted into the inside of the slot 21. The insertion of the limiting block 432 into the slot 21 can achieve the initial positioning of the locking block 43 in the slot 21, preventing the locking block 43 from sliding along the length direction of the slot 21.

[0033] Each of the tops of multiple connecting sector blocks 42 is fixedly connected to a positioning post 44, and the multiple positioning posts 44 pass through the extension sleeve 34. The design of the positioning posts 44 passing through the extension sleeve 34 forms a connecting bridge between the connecting frame 4 and the mounting frame 3. Through a double connection method of snap-fit ​​and through-fit, both installation efficiency and structural stability are taken into account. The inside of the positioning post 44 is provided with a V-shaped extrusion groove 441, and the extrusion crossbar 35 uses the extrusion groove 441 to make the two sides of the positioning post 44 press against the inner wall of the extension sleeve 34. At the same time, the end face of the positioning post 44 is fixedly connected to a locking block 442, and through... The locking block 442 achieves the limiting and fixing of the positioning post 44 and the connecting lug 33. The V-shaped extrusion groove 441 can evenly distribute the extrusion force to both sides of the positioning post 44 when the extrusion crossbar 35 is inserted, so that the two sides of the positioning post 44 expand outward and tightly abut against the inner wall of the extension sleeve 34, forming a reliable frictional fixation. The locking block 442 can engage with the end face of the connecting lug 33 after the positioning post 44 is fully inserted, restricting the positioning post 44 from being pulled out axially, achieving a dual fixing effect of "radial abutment and axial limiting", further improving the anti-loosening ability of the positioning structure.

[0034] like Figure 5 and Figure 6As shown, the connecting frame 4 engages with the mounting frame 3, allowing the headlight to be fixed to the mounting frame 3, which is pre-bolted to the vehicle, via the connecting frame 4. The mounting frame 3 includes a collar 31, which fits onto the outer wall of the lamp body 1 and is tightly fitted to the sealing ring 12 fitted onto the outer wall of the lamp body 1. Multiple alternating mounting lugs 32 and connecting lugs 33 are evenly fixed to the outer circumferential wall of the collar 31. The tight fit between the collar 31 and the sealing ring 12 forms a sealing structure between the lamp body 1 and the mounting frame 3, preventing external rainwater and dust from entering the lamp body and protecting the core components. The alternating mounting lugs 32 and connecting lugs 33 are used to achieve the mounting... The frame 3 is connected to the vehicle's stabilizing bolts, and the connecting lugs 33 provide precise connection points for the connecting frame 4, ensuring balanced stress on the overall structure. The bottom of each connecting lug 33 is fixedly connected to an extension sleeve 34, and the middle of each extension sleeve 34 is fixedly connected to a compression crossbar 35. The extension sleeves 34 can extend the connection length of the connecting lugs 33, providing sufficient insertion space for the positioning post 44 of the connecting frame 4, ensuring the connection depth. The compression crossbar 35, as a key compression component, can cooperate with the compression groove 441 when the positioning post 44 is inserted, and deform the positioning post 44 through mechanical compression to press it against the inner wall of the extension sleeve 34, achieving an interference fit between the connecting frame 4 and the mounting frame 3, and improving the positioning firmness.

[0035] When in use, the heat generated by the lamp body 1 is transferred to the heat sink 2 through the end face and dissipated quickly. The conductive terminal 11 is protected and cooled inside the heat sink 2, ensuring stable power supply. The mounting frame 3 and the connecting frame 4 are firmly connected by compression and locking block 442. The sealing ring 12 prevents external impurities from entering, and the spring 431 eliminates vibration gaps. The overall structure has the advantages of efficient heat dissipation, stable positioning and convenient installation.

Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
