[0052] In existing household appliances, when installing one part on another, such as a sensor on an air conditioner housing or a temperature sensor in an oven, screws are usually used. This requires tools and many operations.

[0053] The main purpose of the present invention is to provide an assembly structure and a household appliance, aiming to at least solve the technical problems in the related art that installation by screw connection requires the use of tools and requires many operating actions.

[0054] See also Figure 1 、 Figure 2 and Figure 3 In one embodiment of the present utility model, the assembly structure 100 includes a mounting seat 1 and a mounting plate 3, wherein one side of the mounting seat 1 in the first direction is a mounting side, and the mounting side has a mounting area 11, and the mounting side is provided with a plurality of limiting protrusions 2 on the periphery of the mounting area 11; the mounting plate 3 is installed in the mounting area 11 and is limited by the plurality of limiting protrusions 2 in the first direction, the second direction and the third direction; wherein the side of the mounting area 11 in the second direction is an insertion side 111, so that the mounting plate 3 can be installed in the mounting area 11 from the insertion side 111, and the plurality of limiting protrusions 2 include a first limiting protrusion 221 located on the insertion side 111, the first limiting protrusion 221 limits the mounting plate 3 at least in the second direction to prevent the mounting plate 3 from escaping from the insertion side 111, and the first limiting protrusion 221 can be elastically deformed to make way for the mounting plate 3 to be installed from the insertion side 111.

[0055] In the technical solution of the present invention, one side of the mounting seat 1 in the first direction is the mounting side, and the mounting side has a mounting area 11, and the mounting side is provided with a plurality of limiting protrusions 2 on the periphery of the mounting area 11, and the mounting plate 3 is installed in the mounting area 11 and is limited by the plurality of limiting protrusions 2 in the first direction, the second direction and the third direction, and the side of the mounting area 11 in the second direction is the insertion side 111, and the plurality of limiting protrusions 2 include a first limiting protrusion 221 located on the insertion side 111, and the first limiting protrusion 221 can be elastically deformed; in this way, when the mounting plate 3 is installed in the mounting area 11, the plurality of limiting protrusions 2 are provided. When the mounting plate 3 is installed to the mounting area 11 on the mounting seat 1, the mounting plate 3 is inserted into the mounting area 11 from the insertion side 111. After being installed to a certain position, the mounting plate 3 is rotated, and the mounting plate 3 is squeezed with the first limiting protrusion 221 so that the mounting plate 3 can be correctly installed in the mounting area 11. The first limiting protrusion 221 elastically recovers and cooperates with other limiting protrusions 2 to limit the mounting plate 3 in various directions, so that the mounting plate 3 is stably installed in the mounting area 11. The entire installation process does not require screws to be completed, and the operation is simple.

[0056] The present design does not limit the number of the mounting areas 11. The number of the mounting areas 11 can be two, three, or even more, and each mounting area 11 corresponds to a mounting plate 3. Of course, when there are multiple mounting areas 11, the periphery of each mounting area 11 is provided with multiple limiting protrusions 2 to limit the corresponding mounting plate 3.

[0057] Because the mounting plate 3 is secured by the elastically arranged first limiting protrusion 221 in cooperation with the other limiting protrusions 2, the elasticity of the first limiting protrusion 221 should not be too great. Otherwise, the first limiting protrusion 221 may be easily deformed by external interference, such as vibration during operation of the device, which may cause the mounting plate 3 to separate from the mounting area 11. The first limiting protrusion 221 can be made of a material such as plastic or hard rubber, and has a certain elastic deformation capacity, but it should not cause the mounting plate 3 to be unstable in the mounting area 11.

[0058] The first limiting protrusion 221 limits the mounting plate 3 at least in the second direction, and the limiting position of the mounting plate 3 can be the middle of one side of the mounting plate 3 in the second direction, or can be a position closer to the edge. Figures 4a-4c , there is a certain angle between the direction in which the mounting plate 3 is inserted from the insertion side 111 and the mounting plate 3 after being installed in the mounting area 11. After most of the mounting plate 3 is located in the mounting area 11, the mounting plate 3 needs to be rotated. During the rotation process, the mounting plate 3 squeezes the first limiting protrusion 221 until the installation is completed; if the first limiting protrusion 221 limits the middle part of the second direction side of the mounting plate 3, it will cause the mounting plate 3 to need to rotate at a larger angle, thereby lengthening the squeezing time of the mounting plate 3 and the first limiting protrusion 221, causing inconvenience to the installation, and at the same time, the elasticity requirement for the first limiting protrusion 221 will be higher.

[0059] In an embodiment of the utility model, the installation area 11 has a limiting side 112 opposite to the insertion side 111 in the second direction, and a first side side 113 and a second side side 114 connecting the insertion side 111 and the limiting side 112; the installation plate 3 has a first side end and a second side end in the second direction, the first side end is set corresponding to the limiting side 112, and the second side end is set corresponding to the insertion side 111; the first limiting protrusion 221 is located at the intersection of the insertion side 111 and the second side side 114. With such a configuration, the first limiting protrusion 221 is used to limit the second side end of the mounting plate 3. Since the first limiting protrusion 221 is located at the intersection of the insertion side 111 and the second side 114, it is equivalent to setting the first limiting protrusion 221 near the end point of the first side end. In this way, after the first side end of the mounting plate 3 is installed from the insertion side 111, the angle of installation can be smaller than that of setting the first limiting protrusion 221 in the middle of the first side end. During the rotation of the mounting plate 3, the contact process between the mounting plate 3 and the first limiting protrusion 221 is shorter, and the installation is more labor-saving. At the same time, the elasticity requirement for the first limiting protrusion 221 will also be relatively lower, so that the mounting plate 3 can be more stable after being fully installed in the mounting area 11.

[0060] The mounting plate 3 has four degrees of freedom in the second direction and the third direction, so the multiple limiting protrusions 2 require at least four parts to limit the four sides of the mounting plate 3. However, due to the production errors of individual components and the elastic setting of the first limiting protrusion 221, it is impossible for the mounting plate 3 to remain completely fixed in the mounting area 11, and there is a possibility of translation or rotation. It is understandable that when the limiting protrusion 2 limits the mounting plate 3 at the middle position of its side, the rotation radius required for the mounting plate 3 to rotate with the limiting protrusion 2 as the rotation point is smaller. When the limiting protrusion 2 limits the side of the mounting plate 3 near the end, the required rotation radius of the mounting plate 3 will be larger. The other limiting protrusions 2 have a stronger rotation restriction on the mounting plate 3, so the limiting effect is better.

[0061] In an embodiment of the present utility model, the multiple limiting protrusions 2 also include a second limiting protrusion 22, a third limiting protrusion 23 and a fourth limiting protrusion 24, the second limiting protrusion 22 is located at the intersection of the limiting side 112 and the second side 114; the third limiting protrusion 23 is located at the intersection of the limiting side 112 and the first side 113; the fourth limiting protrusion 24 is located at the intersection of the insertion side 111 and the first side 113. In this way, the first limiting protrusion 221, the second limiting protrusion 22, the third limiting protrusion 23 and the fourth limiting protrusion 24 limit the position of the mounting plate 3 closer to the ends of the four sides of the mounting plate 3. For example, when the mounting plate 3 rotates with the third limiting protrusion 23, the maximum rotation radius of the mounting plate 3 is equivalent to the length of the line connecting the two diagonals of the mounting plate 3. If the third limiting protrusion 23 limits the middle part of one side of the mounting plate 3, the maximum rotation radius of the mounting plate 3 rotated at this point is equivalent to the length of the line connecting one diagonal and the middle of the opposite side, which is obviously smaller than the length of the line connecting the two diagonals. That is, in this embodiment, the limiting protrusion 2 is set at a position near the end of the side of the mounting area 11 to limit the position near the end of the side of the mounting plate 3, which can improve the limiting effect.

[0062] Of course, one of the limiting protrusions 2 is not limited to limiting only one side of the mounting plate 3. Figure 2 In one embodiment, the first limiting protrusion 221, the second limiting protrusion 22 and the third limiting protrusion 23 limit the two side edges of the mounting plate 3, and when the number of the limiting protrusions 2 is constant, the limiting effect on the mounting plate 3 is improved.

[0063] In order to limit the position of the mounting plate 3 in the first direction, in this embodiment, at least one of the second limiting protrusion 22, the third limiting protrusion 23, and the fourth limiting protrusion 24 is laterally provided with a blocking portion 25 extending to the mounting area 11, and the blocking portion 25 limits the movement of the mounting plate 3 in the first direction. In this way, by the blocking portion 25 extending to the mounting area and cooperating with the mounting base 1, the mounting plate 3 can be limited in the first direction. Among them, the second limiting protrusion 22, the third limiting protrusion 23, and the fourth limiting protrusion 24 can be provided with the blocking portion 25. Alternatively, any two of them can be provided with the blocking portion 25. Alternatively, all three of them can be provided with the blocking portion 25. In one embodiment, in order to maximize the limiting effect of the mounting plate 3 in the first direction, the second limiting protrusion 22, the third limiting protrusion 23, and the fourth limiting protrusion 24 are laterally provided with a blocking portion 25 extending to the mounting area 11.

[0064] The blocking portion 25 is not limited to being provided on the limiting protrusion 2 , but may also be provided separately on the mounting side of the mounting seat 1 , thereby separately limiting the mounting plate 3 in the first direction.

[0065] It should be noted that, when the blocking portion 25 is provided on the limiting protrusion 2, the deformation resistance of the limiting protrusion 2 can be improved, which is equivalent to providing a rib on one side of the limiting protrusion 2 to enhance its bending resistance; especially when the limiting protrusion 2 not only limits one side of the mounting plate 3, for example, the second limiting protrusion 22 has a first limiting side portion for limiting the mounting plate 3 in the second direction, and also has a second limiting side portion for limiting the mounting in the third direction. The second limiting protrusion 22 as a whole limits the sides of the mounting plate 3 in two directions. When the blocking portion 25 is provided on the second limiting protrusion 22 and connects the first limiting side portion and the second limiting side portion, if the first limiting side portion needs to be deformed, it is also necessary to overcome the elasticity of the blocking portion 25 and the second limiting protrusion 22 itself, and the deformation resistance is greatly increased. Therefore, in this embodiment, the blocking portion 25 is provided on the second limiting protrusion 22, the third limiting protrusion 2 and the fourth limiting protrusion 24 to improve the deformation resistance of the limiting protrusions 2 other than the first limiting protrusion 221, and maintain the stability of the mounting plate 3; in addition, even if the first limiting protrusion 221 is made of the same material as the other limiting protrusions 2, the first limiting protrusion 221 can have elastic deformation ability, while the deformation of the other limiting protrusions 2 may be very poor, so that the entire mounting seat 1 and the multiple limiting protrusions 2 can be directly formed with the same material, without the need to use a separate material to separately make the first limiting protrusion 221 when setting the first limiting protrusion 221, and then fix the first limiting protrusion 221 on the mounting seat 1, which can simplify the production process.

[0066] As can be seen from the above, one of the limiting protrusions 2 can limit the two sides of the mounting plate 3 in different directions to improve the stability of the mounting plate 3 installed in the mounting area 11. Due to the elastic setting of the first limiting protrusion 221 itself, it is easier to cause the mounting plate 3 to detach from the first limiting protrusion 221. In order to improve the limiting ability of the first limiting protrusion 221 on the mounting plate 3, please refer to Figure 2 and Figure 3In one embodiment, a mating portion 31 is protrudingly provided on the inner side of the mounting plate 3 at a position corresponding to the first limiting protrusion 221. The first limiting protrusion 221 is configured in a semi-circular shape to define a limiting groove with one side open. The open side of the limiting groove faces the mounting area 11, and the mating portion 31 engages with the limiting groove. With this configuration, after the mounting plate 3 is installed in the mounting area 11, the semi-circular first limiting protrusion 221 cooperates with the limiting groove to limit the mounting plate 3 in multiple directions, thereby reducing the possibility of the mounting plate 3 being separated from the first limiting protrusion 221. During installation, the mounting plate 3 rotates, driving the mating portion 31 to rotate, and the mating portion 31 is squeezed from the opening of the limiting groove into the limiting groove.

[0067] Please refer to Figures 4a to 4c When the fixing plate 3 is installed, the fixing plate 3 is first inserted into the fixing area 11 at an angle from the insertion side 111, and then the fixing plate 3 is rotated into place. During the rotation process, the matching portion 31 will be squeezed with the first limiting protrusion 221 until it enters the limiting groove. During this process, if the side of the matching portion 31 is flat, the rotation radius of the matching portion 31 will gradually increase, and then gradually decrease after passing the corner of the matching portion 31; as can be seen from the above, the elasticity of the first limiting protrusion 221 should not be too good, otherwise the mounting plate 3 after installation will be unstable, which will cause the squeezing force of the first limiting protrusion 221 to gradually increase during the process of gradually increasing the rotation radius of the matching portion 31. When the elastic deformation capacity of the first limiting protrusion 221 is limited, it is easy to cause the matching portion 31 or the first limiting protrusion 221 to be damaged, and it is more difficult to install manually. Therefore, in this embodiment, the matching portion 31 is configured as a cylinder; with such a configuration, during the installation process of the mounting plate 3, the contact portion between the matching portion 31 and the first limiting protrusion 221 is configured in an arc shape, and while its rotation radius does not increase, the arc-shaped edge of the matching portion 31 can guide the rotation, making the mounting plate 3 easier to install.

[0068] Since the matching portion 31 is set as a cylinder, if the side wall of the limiting groove is flat, the contact between the matching portion 31 and the side wall of the limiting groove will be line contact. On the basis that the first limiting protrusion 221 is elastic, the matching portion 31 can easily move in the limiting groove. Furthermore, in order to improve the stability of the matching between the matching portion 31 and the limiting groove; in one embodiment, the first limiting protrusion 221 is set in an arc shape, so that the limiting groove is set as an arc groove. In this way, the contact between the side of the limiting groove and the matching portion 31 is surface contact, and the matching will be more stable.

[0069] Please refer to Figure 2 、 Figure 3 and Figure 4b The second limiting protrusion 22 has a limiting side surface 221 for limiting the mounting plate 3 in the second direction, and the first limiting protrusion 221 has two side ends located in its circumferential direction, and the two side ends of the first limiting protrusion 221 limit the opening side, and the distance between the side end of the first limiting protrusion 221 away from the limiting side surface 221 and the limiting side surface 221 is L1, and the distance between the side of the matching portion 31 away from the limiting side surface 221 and the first side end is L2. If L1 is greater than or equal to L2, it means that the side wall of the limiting groove only abuts against the matching portion 31 in the second direction, and the matching portion 31 is easy to escape from the opening of the limiting groove. Therefore, in order to improve the limiting effect of the limiting groove on the matching portion 31, in this embodiment, L2 is greater than L1, which is equivalent to the limiting groove wrapping the matching portion 31, and the limiting effect is naturally better. Of course, the difference between L2 and L1 should not be too small. If it is too small, it means that the limiting groove has limited wrapping of the matching part 31. Although the limiting effect is improved, the improvement is not large and there is still a possibility of detachment. The difference between L2 and L1 should not be too large. If it is too large, it means that the limiting groove has too strong wrapping of the matching part 31, and it will be difficult to squeeze the matching part 31 into the limiting groove. Therefore, 2≤L2-L1≤4mm, L2-L1 can be 2mm, 3mm, 4mm, etc. When the value of L2-L1 is 2mm, the limiting groove has a certain wrapping ability for the matching part 31, and it is easy to install. When the value of L2-L1 is 4mm, the limiting groove has a good wrapping ability for the matching part 31, but when installing the mounting plate 3, a certain amount of force is required to squeeze so that the matching part 31 enters the limiting groove.

[0070] Please refer to Figure 4a, the fourth limiting protrusion 24 is spaced apart from the end of the limiting side 112 and the end of the first limiting protrusion 221 is spaced apart from the second side 114 to define the insertion side 111, and the distance between the end of the fourth limiting protrusion 24 away from the limiting side 112 and the end of the first limiting protrusion 221 away from the second side 114 is D1, and the dimension of the mounting plate 3 in the third direction is D2. In order to enable the mounting plate 3 to be installed in the mounting area 11 from the insertion side 111, in this embodiment, D1 is greater than D2; although when D1 is less than or equal to D2, the mounting plate 3 can also be installed in the mounting area 11, but in this process, the side of the mounting plate 3 in the third direction will always squeeze the first limiting protrusion 221, so that during the entire installation process, it receives greater resistance, which greatly increases the difficulty of installation. Therefore, in this embodiment, D1 is greater than D2.

[0071] Among them, the difference between D1 and D2 should not be too small. When D1-D2 is too small, it means that when the mounting plate 3 is tilted, the gap between the side of the mounting plate 3 in the third direction and the first limiting protrusion 221 and the fourth limiting protrusion 24 is small. As can be seen from the above, the mounting plate 3 needs to be rotated at last. During this rotation process, due to the change in the rotation radius of the mounting plate 3, the mounting plate 3 may be squeezed with the first limiting protrusion 221 in advance, which brings inconvenience to the installation; D1 and D 2 should not be too large. When D1-D2 is too large, it means that when the mounting plate 3 is tilted, the gap between the side of the mounting plate 3 in the third direction and the first limiting protrusion 221 and the fourth limiting protrusion 24 is large. Either the length of the contact portion of the first limiting protrusion 221 with the mounting plate 3 in the second direction is short, or the fourth limiting protrusion 24 is far away from the first limiting protrusion 221. In either case, the limiting effect on the mounting plate 3 is poor. Therefore, in one embodiment of the present application, 3≤D1-D2≤6mm, and the value of D1-D2 can be 3mm, 4mm, 5mm, 6mm, etc. When the value of D1-D2 is 3mm, the limiting effect is very good and installation is not difficult. When the value of D1-D2 is 6mm, installation is convenient and there is a certain limiting effect.

[0072] Due to the elastic setting of the first limiting protrusion 221, the mounting plate 3 can easily move toward the first limiting protrusion 221 along the second direction. In order to improve the stability of the mounting plate 3 in the second direction, please refer to Figure 2 、 Figure 3 、 Figure 5 and Figure 6In this embodiment, the assembly structure 100 also includes an anti-slip component 4 arranged between the mounting seat 1 and the mounting plate 3, and the anti-slip component 4 is used to limit the mounting plate 3 from falling out from the insertion side 111; the anti-slip component 4 and the action of the anti-slip component 4 limit the movement of the mounting plate 3 along the second direction toward the first limiting protrusion 221, thereby improving the stability of the mounting plate 3.

[0073] The anti-slip component 4 has various forms. For example, a protrusion is provided on one of the mounting seat 1 and the side facing the other, and the movement of the mounting plate 3 is limited by the friction between the protrusion and the other. Although this method has a better limiting effect, during the process of installing the mounting plate 3 to the mounting area 11, it will always be subject to the friction of the protrusion, which makes the installation more difficult. In this embodiment, the anti-slip component 4 includes an anti-slip portion 41 and an anti-slip cooperative portion 42. The anti-slip portion 41 is protruded on the side of the mounting plate 3 facing the mounting seat 1, and the anti-slip cooperative portion 42 is protruded on the side of the mounting seat 1 facing the mounting plate 3. The anti-slip cooperative portion 42 abuts against the side of the anti-slip portion 41 facing the first limiting protrusion 221. In this way, the movement of the mounting plate 3 toward the first limiting protrusion 221 is limited by the abutment between the anti-slip portion 41 and the anti-slip cooperative portion 42. In this way, during the process of mounting the plate 3, only an obstruction will be caused in the process of the anti-slip portion 41 passing over the anti-slip cooperative portion 42, and the time for the anti-slip portion 41 to pass over the anti-slip cooperative portion 42 will not be very long. While having a good limiting effect on the mounting plate 3, it will not cause major obstruction. At the same time, the setting of the matching portion 31 in the abutment between the anti-slip portion 41 and the anti-slip cooperative portion 42 can also make the mounting plate 3 and the mounting side of the mounting seat 1 remain in the same plane.

[0074] In order to facilitate the anti-slip portion 41 to pass over the anti-slip cooperative portion 42, in the present embodiment, at least one of the anti-slip portion 41 and the anti-slip cooperative portion 42 is tapered at one end close to the other; there are three schemes, either the anti-slip portion 41 is tapered at one end close to the anti-slip cooperative portion 42, or the anti-slip cooperative portion 42 is tapered at one end close to the anti-slip cooperative portion 42, or both are tapered at the ends close to the other; in this way, in the process of the anti-slip portion 41 passing over the anti-slip cooperative portion 42, the tapered part can play a guiding role, reducing the obstruction effect between the anti-slip cooperative portion 42 and the anti-slip portion 41, so that the anti-slip portion 41 can more easily pass over the anti-slip cooperative portion 42.

[0075] It can be understood that if the anti-slip portion 41 and the anti-slip matching portion 31 are single-point matched, the limiting effect on the mounting plate 3 is poor, and the mounting plate 3 may also rotate at the contact point between the anti-slip portion 41 and the anti-slip matching portion 31. In order to improve the limiting effect of the overall anti-slip component 4 on the mounting plate 3, in this embodiment, one of the anti-slip portion 41 and the anti-slip cooperative portion 42 is set to be elongated along the third direction to increase the contact area between the anti-slip portion 41 and the anti-slip cooperative portion 42, thereby improving the limiting effect. If the other of the anti-slip portion 41 and the anti-slip cooperative portion 42 is also elongated, even if the anti-slip portion 41 and the anti-slip cooperative portion 42 are The ends of the cooperative part 42 are both tapered, but during the rotation of the mounting plate 3, the contact angles of the anti-slip part 41 and the anti-slip cooperative part 42 at various positions are not only the same, but it is difficult to play a good guiding role. Therefore, in this embodiment, one of the anti-slip part 41 and the anti-slip cooperative part 42 is arranged in a long shape extending along the third direction, and the other is arranged with multiple intervals in the third direction, and the anti-slip part 41 and the anti-slip cooperative part 42 are both tapered near the other end; with such a setting, in the process of the anti-slip part 41 passing over the anti-slip cooperative part 42, no matter from which angle it contacts, the tapered part can play a guiding role, which is convenient for installation.

[0076] It should be noted that the size of the overlapping part of the anti-slip part 41 and the anti-slip cooperative part 42 in the first direction is C, and C should not be too small. If it is too small, the contact part of the anti-slip part 41 and the anti-slip cooperative part 42 in the first direction will be too small, and the limiting effect on the mounting plate 3 will be effective; of course, C should not be too large either. If it is too large, it will make it difficult for the anti-slip part 41 to cross the anti-slip cooperative part 42, which will bring inconvenience to the installation of the mounting plate 3. Therefore, 1≤C≤3mm, C can be 1mm, 2mm, 3mm; when C is 1mm, the overall anti-slip structure has less hindrance to the installation of the mounting plate 3, and at the same time has a certain limiting ability for the mounting plate 3. When C is 3mm, the overall anti-slip structure has a better limiting ability for the mounting plate 3, and at the same time, the installation of the mounting plate 3 will not be too difficult.
