[0001] The present invention relates to the field of assembly technology, and in particular to an assembly device and an electrical appliance provided with the same. Background Art

[0002] With the progress of society and the improvement of people's living standards, various electrical appliances have entered people's lives. Among them, electric heaters have been widely used. For example, electric heaters are widely used in places such as residences, offices, hotels, shopping malls, hospitals, schools, and train carriages.

[0003] An electric heater generally mainly uses natural convection heat transfer and radiation heat transfer. Natural convection heat transfer uses the density difference between hot and cold air as the driving force to drive the indoor air circulation, thereby adjusting the indoor temperature. The heat of radiation heat transfer is easily absorbed by the human body and the clothes worn by the human body, and the human body heating effect is good, and it is energy-efficient.

[0004] A heating element is provided in the electric heater, and the heating element is fixed to the bracket by components that play an auxiliary fixing role. However, the heating element has the problem of being not firmly fixed. In order to firmly fix the heating element, a large number of components are required for auxiliary fixing, resulting in a high cost. Summary of the Invention

[0039] Refer to Figure 1 An embodiment of the present invention provides an assembly device 100, which is applicable to an electrical appliance and is used to assemble a fitting 20 onto a bracket 10. Specifically, the electrical appliance is an electric heater, the fitting 20 is a heating element, and the assembly device 100 is used to assemble the heating element onto the bracket 10. It can be understood that in other embodiments, the type of the electrical appliance is not limited, that is, it is applicable to any electrical appliance that needs to assemble the fitting 20 onto the bracket 10, and no limitation is made here. When the assembly device 100 is applicable to other electrical appliances, the fitting 20 is also a fitting 20 applicable to that electrical appliance.

[0040] Taking the electrical appliance as an electric heater as an example, the technical solution of the present application will be described in detail below. This embodiment is only used as an example for illustration and will not limit the technical scope of the present application. Furthermore, unnecessary components are omitted in the drawings of the embodiment to clearly show the technical features of the present application.

[0041] The electric heater includes an assembly device 100, and the assembly device 100 includes a bracket 10, a fitting 20 and a fastening mechanism 30. The fastening mechanism 30 is used to assemble and fix the fitting 20 on the bracket 10. Among them, the fitting 20 is a heating element, and the heating element can convert electrical energy into heat energy. The heating element can be a heating wire heating element, a thermistor heating element, an electrothermal film heating element, etc.

[0042] The bracket 10 includes a body 11, a resisting part 12 and a cooperating part 13. The resisting part 12 and the cooperating part 13 are both connected to the body 11 and are spaced along a first direction. One end of the fitting 20 abuts against the resisting part 12, and at least part of the fastening mechanism 30 is disposed between the other end of the fitting 20 and the cooperating part 13. The fastening mechanism 30 is fixed to the bracket 10, and under the squeezing action of the cooperating part 13, the fastening mechanism 30 applies a force along the first direction to the fitting 20 to make the fitting 20 abut tightly against the resisting part 12.

[0043] For the assembly device 100 provided by the embodiment of the present invention, the fastening mechanism 30 is abutted and disposed between the other end of the fitting 20 and the cooperating part 13. The fastening mechanism 30 is fixed to the bracket 10, and under the squeezing action of the cooperating part 13, the fastening mechanism 30 applies a force along the first direction to the fitting 20 to make the fitting 20 abut tightly against the resisting part 12. Under the action of the force applied by the fastening mechanism 30 to make the fitting 20 abut tightly against the resisting part 12 and the frictional force applied by the fastening mechanism 30 to the fitting 20, the fitting 20 is not easy to shake relative to the bracket 10, so that the fitting 20 is not easy to detach from the bracket 10, that is, the fitting 20 can be firmly fixed on the bracket 10, ensuring a constant distance between the fitting 20 (heating element) and the thermostat, and only the fastening mechanism 30 needs to be used for the auxiliary fixing parts, reducing the number of parts used and lowering the cost.

[0044] It should be noted here that the fastening mechanism 30 is fixed to the bracket 10. It can be fixed by connecting with the body 11 of the bracket 10, or by connecting with the resisting part 12 of the bracket 10, or by connecting with the cooperating part 13 of the bracket 10, or by fixing with two or three of the body 11, the resisting part 12 and the cooperating part 13, which is not limited herein.

[0045] Refer to Figure 2 , specifically, the resisting part 12 includes a resisting rib 121, and one end of the fitting 20 abuts against the resisting rib 121 of the resisting part 12. More specifically, the resisting part 12 includes two groups of resisting ribs 121 spaced along a second direction intersecting the first direction, and each group of resisting ribs 121 includes two resisting ribs 121 spaced along the second direction. It should be understood that in some other embodiments, one end of the fitting 20 can also abut against the inner surface of the resisting part 12 connected to the resisting rib 121, which is not limited herein.

[0046] The bracket 10 further includes an enclosing portion 14. The enclosing portion 14 is disposed on both sides of the main body 11 along a second direction intersecting the first direction, and the enclosing portion 14 is connected to the resisting portion 12. The resisting portion 12, the enclosing portion 14 and the main body 11 define a receiving cavity 15, and the fitting 20 is disposed in the receiving cavity 15 and abuts against the resisting portion 12.

[0047] The bracket 10 further includes a first limiting portion 16 and a second limiting portion 17 connected to the main body 11. The fitting 20 is limitedly disposed between the first limiting portion 16 and the second limiting portion 17 along a third direction. Specifically, the first limiting portion 16 is connected to the enclosing portion 14 disposed on both sides of the main body 11, a part of the second limiting portion 17 is connected to the enclosing portion 14 disposed on both sides of the main body 11, and the remaining part of the second limiting portion 17 is connected to the resisting portion 12. Refer to Figure 3 , when the fitting 20 is assembled on the bracket 10, first, the fitting 20 is placed in the receiving cavity 15 and one end thereof abuts against the resisting portion 12. At this time, in the third direction, the fitting 20 is located between the first limiting portion 16 and the second limiting portion 17, that is, the first limiting portion 16 and the second limiting portion 17 limit the fitting 20 in the third direction. Generally, after the fitting 20 is assembled in the receiving cavity 15, under the action of gravity, the fitting 20 abuts against the first limiting portion 16, and there is a certain gap between the fitting 20 and the lower surface of the first limiting portion 17. At this time, the fitting 20 is likely to shake relative to the bracket 10 in the first direction and the third direction. When at least a part of the fastening mechanism 30 abuts between the other end of the fitting 20 connected with the wiring portion 22 and the mating portion 13 and is fixed to the bracket 10, under the action of the acting force applied by the fastening mechanism 30 to the fitting 20 to tightly abut against the resisting portion 12 and the frictional force applied by the fastening mechanism 30 to the fitting 20, the fitting 20 is not likely to shake relative to the bracket 10, and the fitting 20 can be firmly fixed on the bracket 10.

[0048] The fitting 20 includes a first main body 21 and a wiring portion 22 connected to the first main body 21. One end of the first main body 21 abuts against the resisting portion 12, and the fastening mechanism 30 abuts between the other end of the first main body 21 connected with the wiring portion 22 and the mating portion 13.

[0049] In a specific embodiment, the fastening mechanism 30 is fixed to the mating portion 13 of the bracket 10. Specifically, the fastening mechanism 30 includes a mating member 31 and a fastener 32. At least a part of the mating member 31 abuts between the other end of the first main body 21 connected with the wiring portion 22 and the mating portion 13. The fastener 32 fixes the mating member 31 and the bracket 10, and the mating member 31 applies the above-mentioned acting force to the fitting 20 along the first direction. It should be understood that in some other embodiments, the fastening mechanism 30 can also be an integral structure, which is not limited herein.

[0050] In one embodiment, a first inclined surface 133 that is inclined relative to the first direction is provided on the side of the engaging portion 13 facing the engaging member 31 (see Figure 4 ). A second inclined surface 318 having the same inclination direction as the first inclined surface 133 is provided on the side of the engaging member 31 facing the engaging portion 13 (see Figure 5 ). The first inclined surface 133 and the second inclined surface 318 cooperate to apply a component force to the engaging member 31 in the first direction, so that the engaging member 31 applies the above-mentioned acting force to the fitting member 20. That is, in this embodiment, the engaging portion 13 and the engaging member 31 cooperate through the first inclined surface 133 and the second inclined surface 318 to apply a force to the engaging member 31, and the engaging portion 13 applies a component force to the engaging member 31 in the first direction, so that the engaging member 31 applies the above-mentioned acting force to the fitting member 20.

[0051] It should be understood that in other embodiments, a third inclined surface that is inclined relative to the first direction may also be provided on the side of the engaging member 31 facing the fitting member 20, and a fourth inclined surface having the same inclination direction as the third inclined surface is provided on the side of the fitting member 20 facing the engaging member 31. The third inclined surface and the fourth inclined surface cooperate to apply the above-mentioned acting force to the fitting member 20 in the first direction, which is not limited herein.

[0052] Specifically, from the end of the engaging portion 13 far from the body 11 to the end close to the body 11, the first inclined surface 133 is inclined toward the direction close to the resisting portion 12, and the inclination direction of the second inclined surface 318 is the same as that of the first inclined surface 133, so as to facilitate the assembly of the engaging member 31.

[0053] The engaging member 31 includes a force-applying portion 311 and a fixing portion 312 that are connected to each other. The force-applying portion 311 is abutted between the other end of the first main body 21 connected with the wiring portion 22 and the engaging portion 13, and the fastener 32 fastens the fixing portion 312 and the engaging portion 13. The above-mentioned second inclined surface 318 is provided on the force-applying portion 311.

[0054] The force-applying portion 311 includes a first sub-force-applying portion 3111 and a second sub-force-applying portion 3112 that are spaced apart (see Figure 4 ). The engaging portion 13 includes a first sub-engaging portion 131 and a second sub-engaging portion 1322 that are spaced apart along the second direction (see Figure 4 ). The first sub-force-applying portion 3111 is abutted between the other end of the first main body 21 connected with the wiring portion 22 and the first engaging portion 13, and the second sub-force-applying portion 3112 is abutted between the other end of the first main body 21 connected with the wiring portion 22 and the second sub-engaging portion 132. By providing the engaging portion 13 as the spaced-apart first sub-engaging portion 131 and second sub-engaging portion 132, and providing the force-applying portion 311 as the spaced-apart first sub-force-applying portion 3111 and second sub-force-applying portion 3112, materials are saved while ensuring firm fixation.

[0055] In a specific embodiment, both the first sub-force-applying portion 3111 and the second sub-force-applying portion 3112 are wedge-shaped structures. That is, the surfaces of the first sub-force-applying portion 3111 and the second sub-force-applying portion 3112 facing the mating portion 13 jointly form the above-mentioned first inclined surface 133, and the surfaces of the first sub-force-applying portion 3111 and the second sub-force-applying portion 3112 facing the fitting 20 are planes arranged along the third direction. Among them, the first direction, the second direction, and the third direction are perpendicular to each other.

[0056] Continuing to refer to Figure 5 , in an embodiment, a gap is formed between the first sub-force-applying portion 3111 and the second sub-force-applying portion 3112. A relief groove 314 is formed through the fixing portion 312 along the first direction at a position facing the gap. The wiring portion 22 passes through the relief groove 314 from one end to the other end and exits from the relief groove 314. The relief groove 314 prevents the fitting 31 from interfering with the wiring portion 22.

[0057] The fixing portion 312 and the force-applying portion 311 (including the first force-applying portion 311 and the second force-applying portion 311) are arranged at an angle. The fixing portion 312 covers the end face of the mating portion 13 away from the body 11 (refer to Figure 6 ), and the fastener 32 passes through the fixing portion 312 from the end face of the fixing portion 312 away from the body 11 and is fixed to the fixing portion 312 and the mating portion 13. Specifically, the fastener 32 passes through the fixing portion 312 from the end face of the fixing portion 312 away from the body 11 and is fixed to the fixing portion 312 and the first sub-mating portion 131.

[0058] Specifically, the fastener 32 is a fastening screw, and the position of the fastener 32 relative to the fixing portion 312 and the mating portion 13 is adjustable to change the magnitude of the above-mentioned acting force. That is, when the fastening screw is tightened relatively, the positions of the fixing portion 312 and the mating portion 13 change. At this time, the position of the force-applying portion 311 relative to the mating portion 13 changes (the force-applying portion 311 moves downward), thereby increasing the above-mentioned acting force; when the fastening screw is loosened relatively, the positions of the fixing portion 312 and the mating portion 13 change. At this time, the position of the force-applying portion 311 relative to the mating portion 13 changes (the force-applying portion 311 moves upward), thereby reducing the above-mentioned acting force.

[0059] In a specific embodiment, the first sub-mating portion 131, the second sub-mating portion 132, the first sub-force-applying portion 3111, and the second sub-force-applying portion 3112 are all hollow structures to save materials and reduce weight.

[0060] Refer to Figure 7 , the fitting 31 includes a first reinforcing rib 316. The first reinforcing rib 316 is arranged inside the first sub-force-applying portion 3111 and the second sub-force-applying portion 3112, and the plane where the first reinforcing rib 316 is located is parallel to the first direction, so that the fitting 31 can withstand a large force in the first direction.

[0061] Continuing to refer toFigure 2 The second sub - mating part 132 includes a second main body 1321 and a second reinforcing rib 1322. The second reinforcing rib 1322 is connected to the side of the second main body 1321 facing the fitting 20, and the second inclined surface 318 is provided on the first sub - mating part 131 and the second reinforcing rib 1322. The plane where the second reinforcing rib 1322 is located is parallel to the first direction. Setting the second sub - mating part 132 to include the second reinforcing rib 1322 can increase the strength of the mating part 13 to ensure the firm fixation of the fitting 20.

[0062] Continue to refer to Figure 7 The fastening mechanism 30 further includes a third reinforcing rib 317. The third reinforcing rib 317 is connected to the side of the fixing part 312 facing away from the avoiding groove 314 and is disposed opposite to the avoiding groove 314 to ensure that the fixing part 312 has sufficient strength.

[0063] Continue to refer to Figure 5 In one embodiment, the fastening mechanism 30 further includes a guiding plate 315. The guiding plate 315 is connected to the first sub - applying - force part 3111 and / or the second sub - applying - force part 3112. The surface of the guiding plate 315 fits with the surface of the mating part 13 to guide the applying - force part 311 between the fitting 20 and the mating part 13.

[0064] In a specific embodiment, guiding plates 315 are connected to both the first sub - applying - force part 3111 and the second sub - applying - force part 3112. Specifically, two guiding plates 315 are connected to both the first sub - applying - force part 3111 and the second sub - applying - force part 3112, and every two guiding plates 315 are spaced apart. In this way, when the fitting 31 needs to be assembled between the fitting 20 and the mating part 13, the two guiding plates 315 connected to the first sub - applying - force part 3111 are in guiding fit with the two side surfaces of the first sub - mating part 131 along the second direction, and the two guiding plates 315 connected to the second sub - applying - force part 3112 are in guiding fit with the two side surfaces of the second sub - mating part 132 along the second direction, so as to assemble the fitting 31 between the fitting 20 and the mating part 13.

[0065] In one embodiment, the fastening mechanism 30 can be assembled in the Figure 8 way, that is, through the sliding fit of the first inclined surface 133 and the second inclined surface 318, the fitting 31 gradually moves downward and finally abuts against the fitting 20, and the fastener 32 fixes the fitting 31 and the mating part 13.

[0066] In another embodiment, the fastening mechanism 30 can also be assembled in the Figure 9 way. The plane of the fitting 31 facing away from the second inclined surface first contacts the fitting, the fitting 31 gradually moves downward, and finally the second inclined surface 318 abuts against the first inclined surface 133, and the fastener 32 fixes the fitting 31 and the mating part 13.

[0067] Another embodiment of the present invention further provides an electrical appliance, including the above-mentioned assembling device 100. Specifically, the electrical appliance is an electric heater, and the fitting 20 in the above-mentioned assembling device 100 is a heating element.

[0068] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0069] The above-described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
