Abstract
Description
Technical Field
[0001] The utility model belongs to the field of vehicle lamp manufacturing, and in particular relates to a connection structure between a vehicle lamp dimming plate and a lamp housing. Background Art
[0002] At present, the lamp housing of a vehicle lamp generally adopts a ball screw structure to connect the light shielding sheet and the lamp housing, which causes the screw part of the ball screw of the lamp housing to protrude downward, not only occupying a large space, but also increasing the material cost.
[0003] The Chinese patent number is "CN201410665381.5" and the patent name is "A headlight ball screw installation structure". It discloses a headlight ball screw installation structure, including a universal joint seat, a ball screw, and a ball screw fixing seat. The universal joint seat is connected to the lamp housing assembly through a snap, and the ball screw fixing seat is connected to the low beam lamp through a snap. The two ends of the ball screw are respectively connected and fixed to the universal joint seat and the ball screw fixing seat. This design occupies a large internal space of the headlight, which limits the position of other structures. In addition, the design is time-consuming to install and the overall cost is high. In particular, this design has no cost competitive advantage for electric bicycles. Utility Model Content
[0004] In view of the above-mentioned prior art, the purpose of the utility model is to provide a connection structure between a vehicle lamp dimming plate and a lamp housing which is small in size and low in cost.
[0005] The technical solution of the utility model is implemented as follows: a connection structure between a vehicle lamp dimming plate and a lamp housing includes a rotating shaft structure and a bearing structure. The rotating shaft structure and the bearing structure are independent of each other and the rotating shaft structure is installed to the bearing structure in a manner that it can rotate around the rotating shaft relative to the bearing structure. The rotating shaft structure or the bearing structure is provided with a deformation part so that the rotating shaft structure or the bearing structure is deformed during the installation process and restores its shape after being installed in place.
[0006] The beneficial effects of such a design are: the bearing structure and the shaft structure are respectively integrated with the dimming plate and the lamp housing. If an integrated molding process is adopted, the economic benefits can be improved and the installation is convenient; the shaft structure or the bearing structure is provided with a deformation part to achieve snap-in connection, and a certain external force can be used during installation to achieve the snap-in connection. Compared with the existing screw installation method, the installation time is reduced and the efficiency is improved, which can reduce the production cost. Especially for the lights of electric bicycles, many lights are set in the middle and can be adjusted only in the vertical direction. The horizontal direction can be in the middle position without multi-directional rotation adjustment, which significantly reduces the protruding structure inside and outside the lamp housing, saves space, and makes the light design more compact.
[0007] Furthermore, one of the rotating shaft structure or the bearing structure is integrally formed with the dimming board or is manufactured separately and then fixed to the dimming board, and the other of the bearing structure and the rotating shaft structure is integrally formed with the lamp housing or is manufactured separately and then fixed to the lamp housing, and rotating shaft structures or bearing structures are provided at both ends of the dimming board or the lamp housing. Such a design can make the rotation smoother and the installation more convenient.
[0008] Furthermore, the dimming plate and at least one end of the lamp housing are installed by means of a snap-fitting manner with the bearing structure and the shaft structure so that the shaft structure can be installed to the bearing structure by being squeezed by external force. The snap-fitting manner is easy to install, does not require other additional structures such as screws to achieve fixation, and the limiting position is relatively stable.
[0009] Furthermore, the dimming plate and the bearing structure and the shaft structure at one end of the lamp housing are installed in a plug-in manner so that the shaft structure can be inserted into the bearing structure at an angle. In this way, the bearing structure or the shaft structure at one end of the dimming plate and the shaft structure or the bearing structure at one end of the lamp housing can be plugged in first, and then the other end can be clamped. The installation and positioning of the plug-in structure is more stable than that of the clamping structure. After the plug-in structure is connected, the plug-in structure will basically not separate as long as the other end does not move.
[0010] Furthermore, the bearing structure includes a supporting portion, a limiting end portion and a deforming portion. The limiting end portion is located at one end of the rotating shaft structure to limit the axial position of the rotating shaft structure. The supporting portion is fixed to the limiting end portion and limits the radial position of the rotating shaft structure. The supporting portion is provided with an opening so that the rotating shaft structure can be inserted from the opening position to the abutment position with the supporting portion. The opening of the supporting portion is provided with a deforming portion so that the installation of the rotating shaft structure will be restricted by the deforming portion. In this way, the supporting portion and the limiting end portion can be limited in the axial and radial directions respectively. The setting of the deforming portion facilitates the radial insertion of the rotating shaft structure into the bearing structure, and can achieve quick clamping.
[0011] Furthermore, the supporting portion is in a semicircular ring shape and is fixed at the limiting end portion, the deforming portion is symmetrically arranged at the opening position of the supporting portion, the deforming portion is in the shape of a long strip and first extends a certain length from the supporting portion along a circumferential arc line to form an arc segment, and then extends a certain length along a straight line in the insertion direction of the rotating shaft or an oblique straight line inclined at a certain angle relative to the insertion direction to form a plug-in section, and then changes direction and extends along a U-shaped line to form a positioning section and finally extends to the dimming plate or the lamp housing. The deforming portion arranged in this way has a simple structure, good elasticity or toughness, and is convenient to process and install.
[0012] Furthermore, the deformation portion includes an upper deformation portion and a lower deformation portion which are symmetrically arranged on the upper and lower sides of the support portion opening, so that the force is evenly applied and the locking and limiting is more stable.
[0013] Furthermore, the rotating shaft structure includes a central shaft, which is first inserted into a bearing structure on one side and is provided with a guide groove so that the rotating shaft structure can be guided by the guide groove when inserted into the bearing structure. Under the action of the guide groove, the central shaft can be more easily inserted into the bearing structure for quick installation.
[0014] Furthermore, the outer end face of the center shaft is at least partially inclined to set the plug-in surface, that is, the end face on the side that is first inserted into the bearing structure is at least partially inclined. When the center shaft is designed to be inserted into the bearing structure, radial and axial effects can be simultaneously applied to the deformation part so that the deformation part undergoes a certain deformation in both the axial and radial directions, reducing the deformation in a single direction, making it easier and more efficient to insert the center shaft into the bearing structure.
[0015] Furthermore, a guide limit block is provided at the limiting end, and the thickness of the guide limit block is the same as the width of the guide groove so that the guide limit block can be inserted into the guide groove when the rotating shaft structure is inserted into the bearing structure. The guide limit block is provided with a first inclined surface and a second inclined surface, and the inclination angle of the first inclined surface is smaller than the inclination angle of the second inclined surface. After the rotating shaft structure is inserted into the bearing structure, the distance between the first inclined surface and the rotating shaft structure is greater than the distance between the second inclined surface and the rotating shaft structure. During the insertion process of the rotating shaft structure, it abuts against the first inclined surface, but after being inserted into place, it only abuts against the second inclined surface or forms a limit. In this way, the design can guide the central axis to be inserted into the bearing structure from the radial direction through the guide limit block, and use the guide limit block to radially limit the central axis to prevent the central axis from separating from the bearing structure.
