Description

Technical Field

[0001] The utility model relates to a heater, in particular to a heater cover plate clamping structure. Background Art

[0002] The shell of the car heater needs to be sealed with the cover plate. Currently, sealant is mainly used to achieve the sealing connection. Since the sealing installation of the cover plate is not the last step, it needs to continue to flow to the next step in the assembly line after gluing and assembly. The sealant needs time to solidify. Therefore, the conventional sealant connection method is prone to cause the position of the cover plate to change, resulting in sealing problems or the cover plate being skewed. Utility Model Content

[0003] In order to solve the above-mentioned problem caused by the cover plate not being fixed during the sealant fixing process, the utility model provides a heater cover plate clamping structure, and the specific technical solution is as follows:

[0004] A heater cover plate clamping structure comprises: a shell, on which a sealing plane, a sealing groove and a plurality of sealing bosses are provided, the sealing groove is provided on the sealing plane, the sealing boss comprises sealing protrusions symmetrically arranged on both sides of the sealing groove and a positioning protrusion arranged between the two sealing protrusions, and the positioning protrusion is located at the bottom of the sealing groove; and a cover plate, on which a sealing folded edge is provided along the edge; wherein the sealing folded edge is inserted into the sealing groove and clamped on the sealing protrusion, and the end of the sealing folded edge abuts against the positioning protrusion.

[0005] Preferably, the sealing protrusion is provided with a compression arc surface arranged opposite to the sealing fold.

[0006] Preferably, the top of the sealing protrusion is provided with a top arc surface.

[0007] Preferably, the height of the sealing fold is not less than the depth between the positioning protrusion and the sealing plane.

[0008] Compared with the prior art, the utility model has the following beneficial effects:

[0009] The utility model provides a heater cover plate clamping structure which fixes the sealing folded edge through a sealing groove and a fixed boss arranged in the sealing groove, so as to fix the cover plate and improve the sealing effect at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The utility model is now further described with reference to the accompanying drawings.

[0017] like Figures 1 to 6 As shown, a heater cover plate clamping structure includes a shell 2 and a cover plate 1. The shell 2 is provided with a sealing plane 20. The sealing plane 20 is provided with a sealing groove 21. The sealing groove 21 is provided with a plurality of sealing bosses 22. The sealing bosses 22 include sealing protrusions 221 and positioning protrusions 222. The sealing protrusions 221 are symmetrically arranged on both sides of the sealing groove 21. The positioning protrusions 222 are connected with the two sealing protrusions 221 and are located at the bottom of the sealing groove 21 to form a U-shaped clamping groove structure. The cover plate 1 is provided with a sealing fold 11 along the edge. The height of the sealing fold 11 is greater than or equal to the depth between the positioning protrusion 222 and the sealing plane 20. The sealing fold 11 is inserted into the sealing groove 21 and abuts against the positioning protrusion 222. The positioning protrusion 222 keeps the cover plate 1 at a set height and makes the cover plate 1 parallel to the sealing plane 20. A clamping arc surface is provided on the side of the sealing protrusion 221, and a top arc surface is provided on the top. The top arc surface and the clamping arc surface are connected by an arc transition. The clamping arc surface and the sealing fold 11 are arranged opposite to each other. The top arc surface facilitates the insertion of the sealing fold 11, and the clamping arc surface can reduce the force area, making it convenient to clamp the sealing fold 11 from both sides of the sealing fold 11.

[0018] During installation, first fill the sealing groove 21 with sealant, then align the sealing fold 11 with the sealing groove 21, insert the sealing fold 11 into the sealing groove 21, and press the sealing fold 11 into two symmetrically arranged sealing protrusions 221, and the end face of the sealing fold 11 rests on the positioning protrusion 222. The sealant is located on both sides of the sealing fold 11 and completely fills the gap between the sealing fold 11 and the sealing groove 21. At the same time, the sealant is also filled between the cover plate 1 and the sealing plane 20 to ensure the sealing effect.

[0019] The symmetrically arranged sealing protrusions 221 are easy to process, reduce the number of sealing protrusions 221 , and can provide reliable clamping pressure to ensure that the cover plate 1 will not separate from the sealing groove 21 in the subsequent process, so that the cover plate 1 is reliably fixed in the sealing groove 21 .

[0020] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementation methods of the present invention without creative work, and these methods will fall within the protection scope of the claims of the present invention.
