DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solution and advantages of the present application clearer and more specific, the present application is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific examples described here are only used to explain the present application and are not used to limit the present application.

[0033] like Figure 1 , Figure 2 As shown, this embodiment proposes that the present application provides a bracket-fixed vehicle lamp, which mainly includes: a housing 100, a metal screw connection 200, a lamp board 300 and an insulating elastic pad 400. In the horizontal plane, the housing 100 can be a long housing 100 (such as Figure 2 As shown), it can also be a square housing 100 (as shown Figure 4 As shown), it can also be other shapes such as a circle. For the convenience of structural description, the shell 100 in the long direction is taken as an example for structural description, and the direction in which the thickness of the shell 100 is located is the up-down direction. An installation space is provided in the shell 100, and the installation space is used to install structures such as the light board 300 and wires. In the horizontal plane, the direction toward the center of the installation space is the inside, and the direction away from the center of the installation space is the outside. The other components of this embodiment are structurally described with reference to the above directions. The metal screw connector 200 is arranged through the bottom of the shell 100 in the up-down direction, and the upper end of the metal screw connector 200 forms an exposed end and is exposed in the installation space. An internal threaded hole 210 is provided at one end of the metal screw connector 200 located outside the shell 100, and the internal threaded hole 210 is used to connect the screw 500. Since the metal screw connector 200 extends upward into the installation space, the depth of the internal threaded hole 210 is deeper. When it is screwed with the screw 500, there are multiple turns of thread to achieve screw connection, thereby greatly reducing the risk of screw thread slippage. Compared with the plastic shell, the internal threaded hole 210 of the metal screw connector 200 has higher strength and is not easily damaged even after multiple disassembly, further improving the product quality. The lamp board 300 is arranged in the installation space and is located on one side of the exposed end of the metal screw connector 200. The lamp board 300 emits light upward, and the LED lamp beads are welded on the PCB board to form a whole, which is easy to assemble. The insulating elastic pad 400 is arranged between the exposed end and the lamp board 300. The insulating elastic pad 400 has insulating properties, thereby effectively separating the metal screw connector 200 from the lamp board 300, and the insulating elastic pad 400 has a certain elasticity, which has a supporting effect on the back of the lamp board 300, ensuring the connection stability of the lamp board 300 in the installation space.

[0034] The bracket-fixed headlight proposed in this embodiment is provided with a metal screw-connector 200 at the bottom of the housing 100 and extending into the installation space inside the housing 100, so that the metal screw-connector 200 extends a certain length in the vertical direction, so that the internal thread has sufficient depth. When the internal thread hole 210 is connected to the screw 500, the number of thread turns matching the screw connection is large, thereby ensuring the stability of the screw connection process. Moreover, the metal screw-connector 200 has a higher structural strength than the structural strength of the internal thread formed by directly opening a threaded hole on the housing 100, and is less likely to cause the problem of thread slippage failure. The stability of the screw 500 for fixing is further ensured. Moreover, the top of the metal screw-connector 200 is exposed in the installation space, and the metal screw-connector 200 is not capped, which is conducive to the realization of the injection molding process, and the metal screw-connector 200 can be moved a certain distance toward the installation space, and will not protrude too much from the outer wall of the housing 100, thereby effectively utilizing the installation space, reducing the thickness of the headlight, and optimizing the headlight structure. By arranging the insulating elastic pad 400 between the exposed end and the lamp board 300 , the metal screw connector 200 is prevented from affecting the wiring on the back of the lamp board 300 , thereby ensuring the operational stability of the circuit on the lamp board 300 .

[0035] like Figure 1 , Figure 2 , Figure 3 As shown, further, the housing 100 in this embodiment specifically includes a bottom shell 110 and a cover 120, and the cover 120 covers the upper opening of the bottom shell 110, so that the bottom shell 110 and the cover 120 are connected to form an installation space inside. A reinforcing boss 130 is provided on the bottom shell 110, and the reinforcing boss 130 extends toward the installation space and protrudes from the inner bottom surface of the bottom shell 110, and the metal screw connector 200 penetrates and is fixed on the reinforcing boss 130. The reinforcing boss 130 extends a certain height in the vertical direction, so that the metal screw connector 200 fixed therein is stably supported, so that the metal screw connector 200 is more stably fixed in the vertical direction. The reinforcing boss 130 protrudes both inside and outside the housing 100, and the height of the protruding portion inside the housing 100 is greater than the protruding portion outside the housing 100, so that the height of the protruding portion outside the housing 100 can be reduced while ensuring that a sufficient depth is provided for the internal threaded hole 210, thereby reducing the thickness of the housing 100. The protruding portion of the reinforcing boss 130 located outside the housing 100 reinforces the metal screw connector 200, making the structural strength higher and the product quality better.

[0036] like Figure 2 , Figure 3As shown, further, a mounting hole 131 is provided in the reinforcing boss 130 in this embodiment, and at least one annular platform 132 is provided on the inner wall of the mounting hole 131. In the specific structure, the reinforcing boss 130 can be cylindrical, and a plurality of annular platforms 132 (for example, 2) can be provided, and the plurality of annular platforms 132 are arranged on the inner wall of the mounting hole 131 at intervals along the up-down direction. The metal screw connector 200 includes: a column 220 and an annular groove 221, and the annular groove 221 is arranged on the side wall of the column 220; the annular groove 221 corresponds to the position of the annular platform 132, and a plurality of annular platforms 132 can be provided. When the metal screw connector 200 is installed on the reinforcing boss 130, the column 220 is embedded in the mounting hole 131, and the annular platform 132 is embedded in the annular groove 221. In this way, in the up-down direction, the outer wall of the metal screw connector 200 and the inner wall of the mounting hole 131 of the reinforcing boss 130 are matched in a concave-convex manner, so that the metal screw connector 200 fixed in the reinforcing boss 130 is not easy to loosen.

[0037] like Figure 2 , Figure 3 As shown, further, the column 220 is also provided with a plurality of limiting grooves 133, which are arranged on the side wall of the column 220 and extend in the vertical direction. The plurality of limiting grooves 133 are evenly distributed around the side wall of the column 220, and can cover a whole circle of the circumferential side wall. Thus, the surface of the column 220 is uneven. Accordingly, a plurality of raised strips 222 are arranged on the inner wall of the mounting hole 131, and the plurality of raised strips 222 are arranged correspondingly to the limiting grooves 133. When the metal screw connector 200 is installed on the reinforcing boss 130, the plurality of raised strips 222 are correspondingly embedded in the plurality of limiting grooves 133, so that the metal screw connector 200 and the reinforcing boss 130 will not rotate in the circumferential direction through the uneven surface, so as to achieve stable limiting, and further strengthen the firmness of the metal screw connector 200 fixed to the reinforcing boss 130.

[0038] The bottom shell 110 and the metal screw connector 200 of this embodiment are formed by secondary injection molding. A plurality of metal screw connectors 200 can be arranged at intervals on the bottom shell 110. For example, two metal screw connectors 200 are arranged symmetrically at a predetermined distance in this embodiment, thereby ensuring the stability of support and connection.

[0039] like Figure 1 , Figure 3As shown, further, an upper stop surface 122 is provided at the edge of the inner wall of the face cover 120 of this embodiment, and a lower stop platform 111 is provided on the inner wall of the bottom shell 110; the lamp board 300 is arranged between the upper stop surface 122 and the top surface of the lower stop platform 111. In the specific structure, a circle of step portions 121 is formed at the edge of the inner wall of the face cover 120, and the lower surface of the step portion 121 forms the upper stop surface 122. The lower stop platform 111 can be arranged at the four corners of the inner cavity of the bottom shell 110 or / and on the inner side wall of the bottom shell, and the lower stop platform 111 extends upward so that a certain distance is spaced between its top surface and the bottom surface of the bottom shell 110. After the lamp board 300 is installed in the installation space, the lamp board 300 can be positioned between the upper stop surface 122 and the lower stop platform 111, and the upper stop surface 122 and the lower stop platform 111 are used to limit the position in the up and down directions. The space enclosed by a circle of side walls of the step portion 121 in the surface cover 120 is used to accommodate the LED lamp bead area on the lamp board 300 .

[0040] like Figure 1 , Figure 3 As shown, further, the insulating elastic pad 400 of this embodiment can be a foam pad. The insulating elastic pad 400 supports the back of the lamp board 300, and the lamp board 300 is pressed against the upper baffle 122 due to the elasticity of the insulating elastic pad 400. Since the insulating elastic pad 400 has a certain elasticity, when the back of the lamp board 300 is pressed against the upper surface of the insulating elastic pad 400, after the upper cover 120 is installed on the bottom shell 110, the upper baffle 122 presses the lamp board 300 downward. At this time, the insulating elastic pad 400 can provide an upward elastic force for the lamp board 300, so that the lamp board 300 can be stably pressed in the installation space by the pressure in the upper and lower directions after installation. The lower baffle 111 serves as an auxiliary support to limit the position of the four feet of the lamp board 300, so that the lamp board 300 is fixed more stably.

[0041] like Figure 1 , Figure 2 , Figure 3 As shown, further, the connection between the bottom shell 110 and the surface cover 120 of this embodiment is provided with an induction welding coil 140, and is used to seal the connection by induction welding. The induction welding coil 140 is provided at the connection between the bottom shell 110 and the surface cover 120, and a full circle of induction welding coils 140 are provided at the edges around the bottom shell 110, so that the connection between the bottom shell 110 and the surface cover 120 is completely covered by the induction welding coils 140. The edges of the bottom shell 110 and the surface cover 120 are welded and fixed by induction welding, and the full circle of induction welding coils 140 weld the edges in a full circle during the induction welding process, so that the bottom shell 110 and the surface cover 120 are fixed more firmly, and the full circle of induction welding coils 140 are used to seal the full circle of the connection by induction welding, and no matching gap is generated at the connection, so that the sealing performance is better, and water vapor will not enter the installation space from the connection, meeting higher waterproof requirements.

[0042] like Figure 1 , Figure 3 As shown, further, a limiting groove 112 is provided at the edge of the bottom shell 110, and the induction welding coil 140 is provided in the limiting groove 112; an external clamping platform 123 is provided around the edge of the surface cover 120, and the external clamping platform 123 is embedded in the limiting groove 112 to limit the induction welding coil 140. The limiting groove 112 is mainly used to install the induction welding coil 140, so that the induction welding coil 140 is stably limited at the edge of the bottom shell 110 and surrounds the edge of the bottom shell 110. The external clamping platform 123 is provided around the surface cover 120, and the external clamping platform 123 is matched with the limiting groove 112, and it is distributed around the edges of the surface cover 120, and can be continuously set or set in multiple sections at intervals. The induction welding coil 140 is set in the limiting groove 112, and the surface cover 120 is covered, so that the external clamping platform 123 is embedded in the limiting groove 112, and then the induction welding is performed.

[0043] like Figure 1 , Figure 3 As shown, further, in this embodiment, a foolproof opening 113 is provided on one circumferential side of the bottom shell 110, and a foolproof boss 124 is correspondingly provided on the outer clamping platform 123 of the surface cover 120; when the surface cover 120 is connected to the bottom shell 110, the foolproof boss 124 is embedded in the foolproof opening 113. For example, the foolproof opening 113 is provided on one or two of the four sides of the bottom shell 110, the foolproof opening 113 can be provided at the edge of the inner wall of the limiting groove 112, so that when the surface cover 120 is installed on the bottom shell 110, it is prevented from being installed upside down.

[0044] like Figure 2 , Figure 4 As shown, further, the metal screw connector 200 of this embodiment is detachably connected to a connecting bracket 600 through a screw 500, and the connecting bracket 600 is used to connect the vehicle frame. The connecting bracket 600 can be in various forms, and a connecting through hole is provided on it, and a bolt 610 can be passed through the connecting through hole to connect to the vehicle frame. The connecting through holes on the connecting bracket 600 have different spacings according to the specifications of the bracket, and connecting brackets 600 of different specifications can be replaced by screwing the screw 500 with the metal screw connector 200. Match with different frames.

[0045] In summary, a bracket-fixed vehicle lamp in the present application is provided with a metal screw connector at the bottom of the shell and extends into the installation space inside the shell. The internal thread can form a sufficient number of turns, and when the internal thread hole is connected with a screw, the screw connection is more stable. Moreover, the top of the metal screw connector is exposed in the installation space, so that the metal screw connector can be moved a certain distance toward the installation space without protruding too much from the outer wall of the shell, thereby effectively utilizing the installation space, reducing the thickness of the vehicle lamp, and optimizing the structure of the vehicle lamp. By providing an insulating elastic pad between the exposed end and the lamp board, the metal screw connector is prevented from affecting the wiring on the back of the lamp board, thereby ensuring the operational stability of the circuit on the lamp board. Connecting brackets of different specifications are replaceable by screwing screws to the metal screw connectors, so that they can be matched with different vehicle frames.
