Description of the Invention: [Technical Field] The present invention relates to a light-emitting device, and more particularly to a vehicle lamp. [Previous Art] Referring to FIG. 1 , a conventional lamp 1 includes a lamp holder 11 having a coupling post and a substantially parabolic shape, and a recess corresponding to the lamp holder u and having a recess corresponding to the coupling post 111 a lamp cover 12 of the portion 121, a bulb 13 disposed on the socket 11, and a bolt 14 that is screwed to the recessed portion 121 and screwed to the coupling post η to join the socket 11 and the lamp cover 12, the bulb 13 The emitted light is reflected by the lamp holder 11 and then emitted through the lamp cover 12. In order to comply with the current traffic regulations, regarding the relevant regulations of the brightness and the illumination range of the lamp, the related art proposes the technique shown in Figures 2 and 3 to increase the brightness and the illumination range of the bulb 13 by increasing the reflection area of the lamp holder 11. However, the distance between the lamp holder 11 and the lamp cover 12 is greatly increased, and the length of the coupling post 111 of the lamp holder 11 is too long, which affects the rigidity of the bonding post 111, and the bonding column ln is prone to breakage. The failure condition causes the lamp holder 11 to be separated from the lampshade 12, causing damage to the lamp rut to affect driving safety. In order to improve the rigidity of the binding post 111 and thereby increase the bonding strength between the lamp holder and the lamp cover 12, and maintain the brightness and illumination range of the bulb 13 to comply with current traffic regulations, the relevant industry utilizes the increased recess 12 The depth of the crucible (as shown by the imaginary line in FIG. 3) reduces the required length of the corresponding bonding post 111, thereby increasing the rigidity of the bonding post 111 to improve the bonding strength between the 5 lamp holder 11 and the lamp cover 12. However, the following disadvantages still need to be improved: 1. Water rusting: Since the depth of the recessed portion 121 is increased, the rainwater stays in the recessed portion 121 and is difficult to discharge in the rainy day, resulting in the passage of the water in the concave portion P 121 The bolt 14 is prone to rust, and the rainwater retained in the recess 121 flows between the lamp cover 12 and the lamp holder, interferes with the operation of the bulb 13, and even damages the bulb 3. 2. Destruction of appearance: Since the depth of the recessed portion 121 is increased, the draft angle of the recessed portion 121 must be increased in the manufacture of the lampshade 12 to facilitate the demolding of the lampshade 12, but this will cause the depressed portion 12 to be depressed. The aperture is greatly increased, which in turn destroys the appearance of the lampshade 12. How to improve the bonding strength between the lamp holder and the lampshade 12 without damaging the appearance, and to avoid the occurrence of water and corrosion, has become a goal that various manufacturers are actively striving to improve. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a vehicle lamp which can improve the bonding strength and avoid the occurrence of water rust and which is more aesthetically pleasing. Therefore, the lamp of the present invention comprises a lamp holder, a lamp cover coupled to the lamp holder, a light-emitting element on which the β-inch is placed, and at least one bonding unit for bonding the lamp holder and the lamp cover. The lamp holder has a body and at least one binding post disposed on the base. The lamp cover is disposed on the base of the lamp holder to cooperate to define an accommodating space in which the binding post is located, and the lamp cover has an inner surface, an outer surface opposite to the inner surface, and at least one recess a recess formed on the outer surface and corresponding to the binding post, at least one extending column extending from the inner surface toward the seat and interposed between the recess and the binding post and at least one axial direction The column extends and communicates with the through portion of the bottom surface of the recess. The illuminating element is disposed on the base of the socket and located in the accommodating space. The bonding unit is disposed on the recessed portion of the lamp cover, the through portion and the lamp post by a fixing member to couple the lamp holder and the lamp cover. The effect of the present invention is that the binding post of the lamp holder and the extension column of the lamp cover cooperate with each other, and the fixing member is inserted through the recessed portion of the lamp cover, the connecting portion of the penetrating portion and the lamp holder, and the lamp holder is improved. The lampshade combines strength and reduces the depth of the recess to avoid water rust and make the appearance of the lamp more beautiful. The above and other technical contents, features and effects of the present invention will be apparent from the following detailed description of the preferred embodiments of the invention. Referring to Figures 4 and 5, a first preferred embodiment of the lamp 2 of the present invention comprises a lamp holder 21, a lamp cover 22 coupled to the lamp holder 21, and a light-emitting element 23 disposed on the lamp holder 21, at least A bonding unit 24 for combining the lamp holder 21 and the lamp cover 22, and at least one positioning unit 25. The lamp holder 21 has a body 211 and at least one coupling post 212 (two coupling posts 212 are shown in FIG. 4) disposed on the base 211. The coupling post 212 has an axial direction extending toward the base 211. a fixing hole portion 214; the lamp cover 22 is coupled to the base 211 of the lamp holder 21 to cooperate to define an accommodating space 2 供 in which the binding post 212 is located, and the lamp cover 22 1332463 has an inner portion a surface 221, an outer surface 222 opposite to the inner surface 221, at least one recess formed on the outer surface 222 and corresponding to the binding post 212, at least one from the inner surface 221 toward the base 211 An extending portion 224 extending in a direction between the corresponding recessed portion 223 and the binding post 212, and at least one through portion 225 extending axially through the extending post 224 and communicating with a corresponding bottom surface of the recessed portion 223, wherein The fixing hole portion 214 of the coupling post 212 is in communication with the corresponding through portion 225, and the diameter of the through portion 225 is larger than the diameter of the corresponding fixing hole portion 214. Further, the length of the coupling post 212 of the socket 21 is greater than The length of the extension post 224 of the lamp cover 22, and The length of the extension post 224 of the lamp cover 22 is again greater than the depth of the recess 223. The structure of the binding post 212 and the corresponding extension post 224 is maintained by the interaction of the binding post 212 with the corresponding extension post 224 and the length of the binding post 212 is greater than the length of the corresponding extension post 224. The rigidity 'further' again causes the length of the extension post 224 to be greater than the depth of the recess 223, reducing the depth of the recess 223 to avoid water accumulation problems. In the preferred embodiment, the socket 21 has two coupling posts 212 disposed on the base 211. Of course, in actual implementation, the socket 21 may have only one disposed on the base 211. The binding post 212 or the coupling post 212 disposed on the base 211 can achieve the same effect as long as the fixing hole 214 of the coupling post 212 can communicate with the corresponding penetration portion 225 of the lamp cover 22. It should not be limited to this embodiment. The light-emitting element 23 is disposed on the base 211 of the socket 21 and located in the accommodating space 20. The coupling unit 24 has a fixing hole portion 214 which is disposed in the recessed portion 223 corresponding to the lamp cover 22, the through portion 225 and the coupling post 212 of the lamp holder 21 to bond the lamp holder 21 and the lamp cover 22 a member 241, and a waterproof member 242 interposed between the fixing member 241 and the bottom surface of the corresponding recess portion 223, wherein the fixing member 241 has a head portion 243' located in the corresponding recess portion 223 a screw portion 244 that is connected to the through portion 225 and the fixing hole portion 214 of the coupling post 212. The waterproof member 242 is sandwiched between the head portion (4) and the recess portion 223 of the fixing member 241. Between the bottom surfaces. In the preferred embodiment, the fixed #241 is a threaded and the waterproof member 242 is a waterproof sheet. The waterproof member 242 can effectively block the flow of liquid from the recessed portion 223 ′ of the lamp cover 22 into the accommodating space 2 经 through the through portion 225 , and the light emitted by the illuminating element 23 is damaged even by excessive moisture. It is particularly worthwhile to mention that the binding post 212 of the socket 21 and the extension post 224 of the lampshade 22 have a thick (four) __ outer peripheral surface (1) and a rough second outer peripheral surface 226, respectively. Therefore, when the screw portion 244 of the fixing member 241 is inserted into the corresponding through portion 225 and the fixing hole portion 214 of the coupling post 212 to join the lamp holder 21 and the lamp cover 22, the lamp cover 22 cannot be used. The screw portion 2 of the fixing member 241 is seen out to make the appearance of the lamp 2 of the present invention more beautiful. The clamping unit 25 has a first clamping portion 251 ′′ disposed on the corresponding extension post 224 and is disposed on the corresponding binding post 212 and correspondingly engaged with the third clamping portion 251 for positioning The extension post 224 and the fourth position portion 252 of the junction 12, in the preferred embodiment, the first positioning portion 251 of the positioning unit '25 is a - stud, and the second positioning portion 252 is a - groove The first positioning portion 251 of the positioning unit 25 may also be a groove, and the second positioning portion 252 may also be a protrusion, as long as the first (four) 251 can correspond to the second; The t-bit portion 252 can achieve the same effect on the library junction', and should not be used as the disclosure of the embodiment. Referring to FIG. 6 'the second preferred embodiment of the vehicle lamp 2 of the present invention is substantially the same as the first preferred embodiment, and the similarities are no longer in common, wherein the difference is that the positioning unit 25 The first positioning portion 251 is a "convex ring", and the second positioning portion 252 is a - ring groove. Of course, the first positioning bit of the positioning unit 25 can also be a ring groove, and the second positioning portion The opposite of 252 is a Μ, as long as the first (four) 251 can be combined with the first 疋 252 252 to achieve the same effect, and should not be limited by the disclosure of the embodiment. - As can be seen from the above, the lamp 2 of the present invention has the following enhancements in comparison with the existing lamp: 1. High bonding strength: under the same accommodating space 20, by the extension column The 224 is reduced in length by the corresponding length of the binding post 212, and the structural column 212 and the extension post 224 are structurally rigid. Therefore, the bonding strength between the socket 21 of the lamp 2 of the present invention and the lamp cover 22 is better. 2. Water rust is not easy: since the depth of the recess 223 is smaller than the length of the extension post 224, and the length of the extension post 224 is smaller than the length of the corresponding binding post 212, the same accommodating space 2 〇 10 1332463 The depth of the depressed portion 223 is shallow, and therefore, the depressed portion 223 of the lamp 2 of the present invention is less prone to water rust. 3. It is more beautiful: since the depth of the recessed portion 223 is shallow, the draft angle of the lampshade 22 of the present invention is smaller than that of the conventional lamp, that is, the aperture of the recessed portion 223 can be effectively reduced. The first outer peripheral surface 213 and the second outer peripheral surface 226 ′ of the coupling post 212 and the extension post 224 make it impossible to see the screw portion 244 of the fixing member 241 from the outside of the lamp cover 22 , so the lamp 2 of the present invention The appearance is more beautiful. In summary, the lamp 2 of the present invention cooperates with the extending post 224 of the lamp holder 21 and the extension post 224 of the lamp cover 22 to improve the bonding strength between the lamp holder 21 and the lamp cover 22, and can reduce the depression. The depth of the portion 223 is reduced and the aperture of the recessed portion 223 is reduced. On the one hand, water rust is less likely to occur, and on the other hand, the lamp 2 of the present invention is more aesthetically pleasing, and the object of the present invention can be achieved. However, the above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, that is, the simple equivalent changes and modifications made by the scope of the invention and the description of the invention, All remain within the scope of the invention patent.
