Description

Technical Field

[0001] This utility model relates to the field of installation technology for automotive lamp housing connectors, and more specifically, to an installation mechanism for automotive lamp housing connectors. Background Technology

[0002] During the installation of the lamp housing, the lamp housing needs to be installed on the connecting component first, and then the lamp housing is installed on the vehicle body using the connector.

[0003] A search revealed that the technical solution with publication number CN215863197U discloses a structure for a car taillight housing mounting hole. It describes a structure comprising a taillight housing body, characterized in that a circular groove is formed on the taillight housing body, a housing mounting hole is formed in the center of the groove, the housing mounting hole further comprising a raised edge, a plurality of radially evenly arranged guide mechanisms on the upper end face of the raised edge, and a drainage groove is formed on one side of the taillight housing body, the bottom of the drainage groove forming an inclined guide surface from the inside out. This invention solves the problem of screw stripping and debris during the assembly of automotive lamps.

[0004] The above-mentioned patent still has shortcomings in actual use. The existing structure requires workers to alternately use electric screwdrivers and positioning fixtures. The installation of a single lamp housing takes a long time. In addition, since the connectors are in an independent and exposed state during the installation process, the installers need to manually stabilize the connectors, which makes the alignment of the lamp housing and the connectors inconvenient.

[0005] Based on this, the present invention discloses an installation mechanism for automotive lamp housing connectors. Utility Model Content

[0006] To address the problems mentioned in the background art, such as the need for workers to alternately use electric screwdrivers and positioning fixtures in existing structures, the long installation time for a single lamp housing, and the inconvenience of manually stabilizing the connectors during installation due to their exposed state, this utility model provides an installation mechanism for automotive lamp housing connectors. The mechanism includes a mounting base with a tapered placement groove at its top. A guide positioning component is mounted on the mounting base. The guide positioning component includes a fixing seat. The top of the mounting base is fixed to a fixed seat at an equal angle to the side of the conical placement groove by bolts. The fixed seat has a rotating cavity. A lower rubber limiting rod is installed on the bottom end face of the inner wall of the rotating cavity by a rotating buckle. A middle rubber limiting rod is fixed to the end of the lower rubber limiting rod. An upper rubber limiting rod is fixed to the top of the middle rubber limiting rod. A limiting spring is installed on the bottom end face of the rotating cavity. The top of the limiting spring is connected to the lower rubber limiting rod by a fixing buckle. A pulling component is installed on the lower rubber limiting rod.

[0007] As a further improvement to this technical solution, the pulling assembly includes a pulling hole. The pulling hole is formed through the bottom of the inner wall of the rotating cavity near the opening. The mounting base has a structural cavity inside. Through holes are formed at equal angles on the top end face of the inner wall of the mounting base at the side of the conical placement groove. The through holes communicate with the interior of the structural cavity. A central shaft is rotatably installed at the center of the interior of the structural cavity. A pulling rope is wound around the outside of the shaft of the central shaft.

[0008] As a further improvement to this technical solution, an installation frame is installed on the internal vertical structural surface of the structural cavity. Each installation frame corresponds to a fixed seat. The end of the frame of each installation frame is rotatably mounted with a limiting roller through a pin. A limiting groove is opened on the outer arc surface of the limiting roller. The end of the pulling rope passes through the limiting groove on the limiting roller and extends through the through hole and the pulling hole, and then is connected to the lower rubber limiting rod through a connecting ring.

[0009] As a further improvement to this technical solution, a first shaped gear is fixedly connected to the top of the central shaft, a rotating shaft is installed on the outer side of the mounting base, the end of the rotating shaft is inserted into the interior of the structural cavity and a second shaped gear is installed thereon, the second shaped gear meshes with the first shaped gear, and an adjustment knob is installed at the end of the rotating shaft away from the second shaped gear.

[0010] As a further improvement to this technical solution, the rotation trajectory of the second irregular gear does not contact the pulling trajectory of the pulling rope.

[0011] As a further improvement to this technical solution, the vertical center line of the opening of the pulling hole coincides with the vertical center line of the opening of the through hole, the vertical center line of the opening of the through hole coincides with the vertical center line of the limiting roller, the limiting spring does not deform when it is not in operation, and the middle rubber limiting rod is in a vertical state at this time.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. In the installation mechanism of the automotive lamp housing connector, the pre-positioning and coarse clamping effects are achieved through the cooperation of the guide positioning component, avoiding repeated adjustment of the lamp housing angle and installation position, eliminating the need for workers to alternately use electric screwdrivers and positioning fixtures, and saving lamp housing installation time.

[0014] 2. In the installation mechanism of the automotive lamp housing connector, the working range of the guide positioning component is adjusted by the cooperation of the pulling component, so as to realize the installation of lamp housings and connectors of different shapes and sizes.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Therefore, this utility model provides an installation mechanism for an automotive lamp housing connector, see [link to relevant documentation]. Figures 1-2As shown, it includes a mounting base 1, with a conical placement groove 2 on the top of the mounting base 1. A guide positioning assembly is installed on the mounting base 1, and the guide positioning assembly includes a fixing base 3. The fixing base 3 is fixed to the top of the mounting base 1 at an equal angle to the side of the conical placement groove 2 by bolts. A rotating cavity 4 is opened on the body of the fixing base 3. A lower rubber limiting rod 5 is installed on the bottom end face of the inner wall of the rotating cavity 4 by a rotating buckle. A middle rubber limiting rod 6 is fixed to the end of the lower rubber limiting rod 5, and an upper rubber limiting rod 7 is fixed to the top of the middle rubber limiting rod 6. A limiting spring 8 is installed on the bottom end face of the rotating cavity 4. The top of the limiting spring 8 is connected to the lower rubber limiting rod 5 by a fixing buckle. A pulling assembly is installed on the lower rubber limiting rod 5. The conical placement groove 2 is a sunken conical groove. The opening direction of the rotating cavity 4 is located on one side of the top of the fixed base 3 and on the other side close to the conical placement groove 2. The lower rubber limiting rod 5 tends to retract from bottom to top. When the limiting spring 8 is in a compressed state, the middle rubber limiting rod 6 tends to retract slightly from bottom to top, and the upper rubber limiting rod 7 tends to extend outward from bottom to top, so as to provide a pre-guiding effect for the placement of the lamp housing. When the top of the middle rubber limiting rod 6 tilts outward a short distance, the limiting spring 8 does not deform.

[0023] During operation, the structural design of the guide positioning component allows the connector to be installed to be placed statically within the working range of the upper rubber limiting rod 7. A downward force is applied, causing the bottom of the connector to insert into the conical placement groove 2, while its top is engaged between the rods of the middle rubber limiting rod 6. At this time, the top of the middle rubber limiting rod 6 is tilted outward, achieving a pre-clamping and positioning effect with the connector. This avoids the need for the operator to constantly hold the connector during subsequent lamp housing installation. Then, the lamp housing is placed between the upper rubber limiting rods 7, and a downward force is applied, causing the lamp housing to enter the working range of the middle rubber limiting rod 6. At this time, the middle rubber limiting rod 6 acts as a guide post, achieving a coarse positioning effect. This avoids repeated adjustments to the angle and installation position of the lamp housing, eliminating the need for workers to alternate between using electric screwdrivers and positioning fixtures, thus saving lamp housing installation time.

[0024] Further, see Figure 1 , Figures 3-4As shown, the pulling assembly includes a pulling hole 9. The pulling hole 9 is provided through the bottom of the inner wall of the rotating cavity 4 near the opening. The mounting base 1 has a structural cavity 10 inside. The top end face of the inner wall of the mounting base 1 has a through hole 11 at an equal angle on the side of the conical placement groove 2. The through hole 11 communicates with the interior of the structural cavity 10. A central shaft 12 is rotatably installed at the center of the interior of the structural cavity 10. A pulling rope 13 is wound around the outside of the shaft of the central shaft 12. When the lower rubber limit rod 5 is rotated downward by pulling the rope 13, the limit spring 8 is compressed and generates a reaction force. After the pulling force on the rope 13 is removed, the reaction force on the limit spring 8 pushes the lower rubber limit rod 5 to move upward to its original position. The vertical cross-section of the structural cavity 10 is concave, ensuring that the opening space of the conical placement groove 2 does not contact the pulling trajectory of the rope 13. Each rope 13 is arranged from bottom to top on the outside of the shaft of the central shaft 12, and they do not interfere with each other when rotating and winding.

[0025] Mounting brackets 14 are installed on the vertical structural surface inside the structural cavity 10. Each mounting bracket 14 corresponds to a fixed seat 3. A limiting roller 15 is rotatably mounted on the end of the bracket body of each mounting bracket 14 via a pin. A limiting groove is formed on the outer arc surface of the limiting roller 15. The end of the pulling rope 13 passes through the limiting groove on the limiting roller 15, passes through the through hole 11 and the pulling hole 9, and then is connected to the lower rubber limiting rod 5 via a connecting ring. The installation positions of the limiting rollers 15 are all at the same horizontal height, ensuring that the pulling rope 13 is in a taut state when pulled inside the structural cavity 10, and reducing the friction of the pulling rope 13 inside the through hole 11.

[0026] A first shaped gear 16 is fixed to the top of the central shaft 12. A rotating shaft 17 is mounted on the outer surface of the mounting base 1. The end of the rotating shaft 17 is inserted into the interior of the structural cavity 10 and a second shaped gear 18 is mounted thereon. The second shaped gear 18 meshes with the first shaped gear 16. An adjusting knob 19 is mounted on the end of the rotating shaft 17 away from the second shaped gear 18. When a rotational force is applied to the adjusting knob 19, the rotating shaft 17 drives the second shaped gear 18 to rotate, and the first shaped gear 16 rotates accordingly, causing the central shaft 12 to rotate as well, thus winding up the pull rope 13.

[0027] The rotation trajectory of the second irregular gear 18 does not contact the pulling trajectory of the pulling rope 13.

[0028] The vertical center line of the opening of the pull hole 9 coincides with the vertical center line of the opening of the through hole 11. The vertical center line of the opening of the through hole 11 coincides with the vertical center line of the limit roller 15. The limit spring 8 does not deform when it is not in operation, and the middle rubber limit rod 6 is in a vertical state at this time.

[0029] During operation, by engaging the pull assembly, when installing lamp housings of different sizes and shapes, a rotational force can be applied to the adjustment knob 19. The rotating shaft 17 drives the second irregular gear 18 to rotate. With the cooperation of the first irregular gear 16, the central shaft 12 rotates, causing the pull rope 13 on it to wind and rotate. Under the limiting action of the limiting roller 15, the pull rope 13 pulls the lower rubber limiting rod 5 to rotate downward around the rotating buckle, causing the top of the middle rubber limiting rod 6 to tilt towards the center of the conical placement groove 2. The working range of the upper rubber limiting rod 7 is then reduced, thereby adjusting the working range of the guide positioning assembly and enabling the installation of lamp housings and connectors of different shapes and sizes.

[0030] In summary, this effectively solves the problems of existing structures requiring workers to alternate between using electric screwdrivers and positioning fixtures, resulting in long installation times for a single lamp housing. Furthermore, during installation, the connectors are exposed and require manual stabilization by installers, leading to inconvenience in aligning the lamp housing with the connectors.
