Description

Technical Field

[0001] The utility model relates to the field of front end frames, in particular to a split front end frame. Background Art

[0002] A Chinese patent with announcement number CN221293216U discloses a split front end structure of a car headlight arm, including a front end frame and a left lamp bracket and a right lamp bracket respectively arranged on the left and right sides of the front end frame, a plurality of first bolt holes opposite to each other are arranged on one end of the front end frame close to the left lamp bracket and on the left lamp bracket, and the front end frame and the left lamp bracket are fixed by bolts and nuts, a plurality of second bolt holes opposite to each other are arranged on the front end frame close to the right lamp bracket and on the right lamp bracket, and the front end frame and the right lamp bracket are also fixed by bolts and nuts.

[0003] When fixing the left lamp bracket and the front end frame in the above structure, it is necessary to first move the left lamp bracket to the front end frame so that the first bolt hole on the left lamp bracket is aligned with the first bolt hole on the front end frame, and then the bolt is passed through the first bolt hole and the front end frame is fixed to the left lamp bracket by the nut. The right lamp bracket is the same as the front end bracket. However, when the front end frame and the left lamp bracket are fixed to each other, it is necessary to first move the left lamp bracket until the first bolt hole on the left lamp bracket is aligned with the first bolt hole on the front end frame. Then, when the front end frame and the left lamp bracket are fixed with the bolts and nuts, it is still necessary to maintain the state of the adjacent ends of the front end frame and the left lamp bracket being fitted together manually or mechanically. Only then can the front end frame and the left lamp bracket be fixed to each other by the bolts and nuts. The fixing of the right lamp bracket to the front end frame is the same, which makes the steps for fixing the front end frame to the left lamp bracket and the right lamp bracket more cumbersome and time-consuming. Utility Model Content

[0004] The utility model addresses the disadvantage of the prior art that when the front end frame and the left lamp bracket are fixed to each other, it is necessary to first move the left lamp bracket until the left lamp bracket is aligned with the first bolt holes on the front end frame, and then it is necessary to maintain the adjacent sides of the two in a state of mutual fit through manual or mechanical assistance when the two are fixedly connected, and the right lamp bracket and the front end frame are fixed to each other in the same manner, thereby resulting in the disadvantage that the fixing process of the front end frame and the left lamp bracket and the right lamp bracket is relatively cumbersome and time-consuming, and provides a split front end frame that is easy to fix.

[0005] In order to solve the above technical problems, the utility model is solved by the following technical solutions:

[0006] A split front end frame comprises a front end frame body, wherein the front end frame body comprises a middle frame and a left end frame and a right end frame respectively fixed to both sides of the middle frame by bolt and nut assemblies, a first positioning component for positioning when the left end frame and the right end frame are installed on both sides of the middle frame is arranged between the side opposite to the left end frame and the right end frame and the two side walls, the first positioning component comprises overlapping blocks symmetrically arranged on the side opposite to the left end frame and the right end frame for partial overlapping of the middle frame and vertically upward positioning pins respectively arranged on the two overlapping blocks, positioning holes for partial insertion of the positioning pins are respectively arranged at both ends of the middle frame, and second positioning components for positioning the left end frame and the right end frame are respectively arranged below the front end frame body.

[0007] By adopting the above scheme, the overlapping blocks respectively arranged on the opposite sides of the left end frame and the right end frame can be overlapped on the overlapping blocks when the middle frame is fixed to the two ends, and the positioning pins respectively arranged on the two overlapping blocks can be partially inserted into the positioning holes on both sides of the middle frame when the middle frame is overlapped on the overlapping blocks, so as to position the position of the middle frame, thereby facilitating the operator to fix the left end frame and the right end frame on both sides of the middle frame through the bolt and nut assemblies, and the second positioning component can position the position of the left end frame and the right end frame, so that when the two sides of the middle frame are overlapped on the two overlapping blocks, the side walls on both sides of the middle frame can fit with the side walls of the left end frame and the right end frame, thereby making the fixation between the middle frame and the left end frame and the right end more convenient.

[0008] Preferably, the second positioning component includes a positioning block arranged below the front end frame body, and the positioning block is provided with positioning grooves for partially inserting the bottom ends of the left end frame and the right end frame to position the left end frame and the right end frame.

[0009] By adopting the above scheme, the two positioning grooves provided on the positioning block can be respectively provided for partial insertion of the left end frame and the right end frame to fix the position of the left end frame and the right end frame, thereby fixing the distance between the left end frame and the right end frame, so that when the middle frame is overlapped on the overlap block, the side walls on both sides of the middle frame can fit with the two opposite side walls of the left end frame and the right end frame, thereby facilitating the operator to fix the middle frame to the left end frame and the right end frame through the bolt and nut assembly.

[0010] Preferably, two positioning blocks are provided and are respectively arranged below the left end frame and the right end frame.

[0011] By adopting the above solution, the positioning block is arranged into two separate pieces, which can reduce the materials required for positioning the left end frame and the right end frame, thereby reducing the production cost.

[0012] Preferably, an adjusting component capable of adjusting the distance between the two positioning blocks is provided below the positioning block.

[0013] Preferably, the adjusting component comprises an adjusting plate arranged below the positioning block, the adjusting plate is provided with a sliding groove for two positioning blocks to be inserted into and slide therein, and the sliding groove is provided with a driving component for driving the two positioning blocks in the sliding groove to move synchronously closer or farther away.

[0014] By adopting the above scheme, the two positioning blocks arranged in the sliding groove can be driven to move closer or farther synchronously through the provided driving component. When the size of the front end frame body changes, the distance between the two positioning blocks can be adjusted by the driving component, thereby improving the applicability of the positioning blocks.

[0015] Preferably, the driving component includes a bidirectional screw extending in the sliding groove along the sliding direction of the positioning block and an operating block concentrically fixed to the middle of the bidirectional screw and used to drive the bidirectional screw to rotate. The two ends of the bidirectional screw are rotatably connected to the side walls of the sliding groove. The two positioning blocks are respectively arranged on both sides of the bidirectional screw, and threaded holes matching the bidirectional screw are respectively arranged on the two positioning blocks.

[0016] By adopting the above scheme, when the size of the front-end frame body changes, a tool can be used to rotate the operating block to rotate the operating block, thereby causing the operating block to drive the bidirectional screw to rotate. When the bidirectional screw rotates, the positioning blocks arranged at both ends of the bidirectional screw can be driven to move in the sliding groove, thereby realizing the adjustment of the positions of the two positioning blocks and improving its applicability.

[0017] Preferably, the cross section of the operating block is a regular hexagon.

[0018] By adopting the above scheme, setting the cross section of the operating block into a regular hexagon can facilitate workers to rotate the operating block through tools. When the operating block rotates, it will drive the bidirectional screw to rotate, so that the two positioning blocks set at both ends of the bidirectional screw are close to or away from each other.

[0019] The utility model has remarkable technical effects due to the adoption of the above technical scheme: the overlapping blocks respectively arranged on the opposite sides of the left end frame and the right end frame can be overlapped on the overlapping blocks when the middle frame is fixed to the two, and the positioning pins respectively arranged on the two overlapping blocks can be partially inserted into the positioning holes on both sides of the middle frame when the middle frame is overlapped on the overlapping blocks, so as to position the middle frame, thereby facilitating the operator to fix the left end frame and the right end frame on both sides of the middle frame through the bolt and nut assembly, and the second positioning component can position the left end frame and the right end frame, so that when the two sides of the middle frame are overlapped on the two overlapping blocks, the side walls on both sides of the middle frame can fit with the side walls of the left end frame and the right end frame, thereby making the fixation between the middle frame and the left end frame and the right end more convenient.
