[0041] This utility model proposes a housing assembly 100 for use in heaters.

[0042] Please see Figures 1 to 4 In one embodiment of this utility model, the heater includes a common baseboard heater. The housing assembly 100 includes a rectangular shell body 1 and a side cover 2 disposed on the shell body 1. The side cover 2 is detachably connected to the shell body 1 by a snap-fit ​​structure, such as... Figure 2 As shown, at least one side end of the shell body 1 is provided with a support portion 11. The support portion 11 has a support platform 111 with a recessed folded edge structure. The upper support surface of the support platform 111 is lower than the height of the upper surface of the shell body 1. The side cover 2 is detachably provided at the side end of the shell body 1. The side cover 2 is provided with an abutment portion 21 on the side facing the side end of the shell body 1. The bottom end of the abutment portion 21 abuts against the support platform 111 so that the upper surface of the shell body 1 is flush with the upper surface of the side cover 2.

[0043] Furthermore, one of the supporting part 11 and the abutting part 21 is provided with a limiting part 112, and the other is provided with a limiting mating part 211. The limiting part 112 and the limiting mating part 211 abut against each other, and the supporting platform 111 supports the abutting part 21 to limit deformation at the connection between the side cover 2 and the shell body 1. Specifically, during the use of the heater, the supporting platform 111 and the abutting part 21, and the limiting part 112 and the limiting mating part 211 can prevent the side cover 2 and / or the shell body 1 from warping or denting, avoid the formation of a height difference at the connection between the side cover 2 and the shell body 1, and help maintain the overall aesthetics of the shell assembly 100.

[0044] Of course, in some other embodiments of this utility model, the outer surfaces of the side cover 2 and the shell body 1 are not necessarily flush. For example, there may be a certain height difference between the upper surfaces of the side cover 2 and the shell body 1. The supporting part 11 and the abutting part 21 can prevent the height difference from expanding or shrinking, so as to maintain its shape unchanged. In this solution, the supporting part 11 and the abutting part 21 are used to limit the deformation of the side cover 2 and the shell body 1 at the connection. This structure can be provided on the upper surface, bottom surface, front side or rear side of the shell assembly 100, etc., without specific limitations. This solution is mainly illustrated by limiting the deformation of the upper surface of the shell assembly 100.

[0045] It should be noted that the limiting part 112 and the limiting mating part 211 in this embodiment can be configured as a fitting structure of protrusion and groove, a snap-fit ​​structure of buckle and lock hole, an abutting structure of stepped surface and baffle, etc., to limit the deformation of the side cover 2 and / or shell body 1, or control the degree of deformation of the side cover 2 and / or shell body 1 within an acceptable range. In the heater, in addition to being affected by the heating element, the side cover 2 and shell 1 may also deform under the long-term influence of factors such as material aging, moisture erosion, oxidation, ambient temperature, and mechanical stress. The bearing part 11 and the abutting part 21 can not only ensure the flatness of the installation, but also prevent the deterioration of the external structure of the shell assembly 100 during long-term use.

[0046] like Figures 2 to 4 As shown, in one embodiment of this utility model, a limiting part 112 is provided on the supporting part 11. The limiting part 112 is spaced apart from the supporting platform 111 and is located above the supporting platform 111 along the height direction of the housing assembly 100. Figures 5 to 7 It is understood that the bottom end of the abutting part 21 abuts against the upper surface of the support platform 111, and the limiting part 112 abuts against the limiting mating part 211 in the height direction, so that at least part of the structure of the abutting part 21 is engaged between the support platform 111 and the limiting part 112. When the side cover 2 is deformed by external factors, the limiting part 112 and the support platform 111 can cancel out its deformation stress, avoiding the problem of the side cover 2 and / or the edge of the shell body 1 warping upward or sinking downward.

[0047] It should be noted that in some other embodiments of this utility model, the limiting part 112 may also be provided on the abutting part 21, while the limiting mating part 211 is provided on the bearing part 11. The specific details are not limited. When the limiting part 112 is provided on the bearing part 11, the limiting part 112 may also be provided below the bearing platform 111 so as to cooperate with the bearing platform 111 to abut the limiting mating part 211 to prevent it from deforming. This can be set according to actual needs.

[0048] like Figures 2 to 4 As shown, in one embodiment of the present invention, the supporting part 11 has a first sidewall 113, the upper surface of the supporting platform 111 is arranged parallel to the upper surface of the shell body 1, the first sidewall 113 is arranged perpendicular to the upper surface of the supporting platform 111, the limiting part 112 is a protrusion 1121 provided on the first sidewall 113 and protruding outward, the abutting part 21 has a second sidewall 212 on the side facing the side end of the shell body 1, the second sidewall 212 is arranged parallel to the first sidewall 113, and the limiting mating part 211 is a limiting groove 211a provided on the second sidewall 212, the opening of the limiting groove 211a is opened facing the first sidewall 113.

[0049] When the side cover 2 is installed onto the shell body 1, the first side wall 113 fits against the second side wall 212, and the protrusion 1121 is engaged in the limiting groove 211a. The lower end of the protrusion 1121 abuts against the bottom wall of the limiting groove 211a in the height direction, and the upper surface of the support platform 111 abuts against the lower end of the abutment 21 for limiting. It can be understood that setting the first side wall 113 and the second side wall 212 to fit together helps to reduce the gap at the connection between the side cover 2 and the shell body 1, and further improves the appearance flatness of the shell assembly 100.

[0050] like Figures 1 to 5 As shown, in one embodiment of this utility model, a plurality of protrusions 1121 are spaced apart on the first sidewall 113 of the bearing portion 11 along the width direction of the housing assembly 100, and a plurality of limiting grooves 211a are spaced apart on the second sidewall 212 of the abutting portion 21 along the width direction of the housing assembly 100. Each protrusion 1121 is correspondingly engaged in a limiting groove 211a. It can be understood that the spaced protrusions 1121 and the multiple limiting grooves 211a cooperate to form multiple abutment points between the side cover 2 and the housing body 1, so as to disperse the stress generated when the side cover 2 and / or the housing body 1 deforms, and prevent local warping of the side cover 2 and / or the housing body 1. The number of protrusions 1121 and the corresponding limiting grooves 211a can be adapted to the width of the housing body 1 and the side cover 2.

[0051] In this design, the side cover 2 and the shell body 1 are detachably connected via a snap-fit ​​structure. This snap-fit ​​assembly reduces the use of screws and other components. Depending on the installation structure, the side cover 2 can be installed onto the shell body 1 vertically, horizontally, or at an angle and secured in place. For example, such as... Figure 6 and Figure 7 In the embodiment shown, the side cover 2 is fastened by being installed downward along the height direction of the housing assembly 100. During installation, the abutting part 21 of the side cover 2 is first placed above the support platform 111, and the second side wall 212 is close to or abuts against the first side wall 113. The side cover 2 is moved downward to perform the fastening operation.

[0052] Furthermore, such as Figure 4 and Figure 5 As shown, the abutment portion 21 is provided with a clearance groove 21a that extends through the length of the housing assembly 100. The lower end of the clearance groove 21a has a slot, and the limiting groove 211a is provided on both sides of the housing assembly 100 in the width direction, so that the abutment portion 21 is located in the middle part of the two clearance grooves 21a to form an elastic portion 214. The upper end of the elastic portion 214 is connected to the housing and is suitable for generating elastic deformation. During the downward movement of the side cover 2, the lower end of the elastic portion 214 abuts against the upper surface of the protrusion 1121, so that the elastic portion 214 generates elastic deformation. When the side cover 2 is fastened in place, the elastic portion 214 rebounds, and the protrusion 1121 is inserted into the limiting groove 211a to complete the fastening.

[0053] It should be noted that when the side cover 2 is installed along the height direction, a sliding groove, slider or other structure along the height direction can be provided on the shell body 1 and the side cover 2 to restrict the side cover 2 from moving along the length direction of the shell body 1. When the side cover 2 is installed along the horizontal or inclined direction, the elastic part 214 can be adjusted according to the direction of the protrusion 1121 so as to cooperate with other structures to limit the side cover 2 to be installed on the shell body 1. No specific limitation is made here.

[0054] like Figures 2 to 5 As shown, in one embodiment of this utility model, both the shell body 1 and the side cover 2 have a certain width. The abutment portion 21 and the support platform 111 extend along the width direction of the shell assembly 100, so that the upper surface of the support platform 111 is continuous and extends along the width direction of the shell assembly 100. The abutment portion 21 extends along the width direction of the shell assembly 100 and abuts against the support platform 111, which can effectively prevent the side cover 2 from being deformed by dents. Furthermore, the continuous support platform 111 can provide stable support for the side cover 2, which is beneficial to improving the structural strength of the shell assembly 100.

[0055] like Figure 5 and Figure 6As shown, in one embodiment of this utility model, a mounting groove 2a is provided on the side of the side cover 2 facing the side end of the shell body 1, making the side cover 2 a thin-walled structure. The mounting groove 2a can be used to install components such as the main control board and drive motor. The abutment part 21 is provided at the upper edge of the groove opening of the mounting groove 2a and protrudes downward. The distance from the edge of the groove opening to the bottom of the abutment part 21 matches the distance from the upper surface of the shell body 1 to the upper surface of the support platform 111, so that the upper surface of the side cover 2 is flush with the upper surface of the shell. Since the wall thickness of the side cover 2 is relatively thin, it is prone to deformation under the influence of heat or other factors. By providing the abutment part 21, the upper edge of the groove opening can be effectively prevented from warping or sinking. Of course, in this embodiment, the structure of the abutment part 21 and the support part 11 is used to correspond to the upper surface of the shell assembly 100. In some other embodiments of this utility model, this structure can also be provided on the side surface or bottom surface of the shell assembly 100.

[0056] like Figures 5 to 7 As shown, in one embodiment of this utility model, the bottom end of the abutment portion 21 is further provided with a downwardly protruding insertion portion 213. The support platform 111 has a corresponding insertion hole 111a that matches the shape of the insertion portion 213. This insertion hole 111a is provided through the support platform 111 along the height direction of the housing assembly 100, allowing the side cover 2 to be installed along the height direction. During the assembly of the housing assembly 100, the insertion portion 213 is inserted into the insertion hole 111a during the downward installation of the side cover 2, thereby restricting the side cover 2 from moving along the length and width directions of the housing body 1. Combined with the limiting portion 112 and the limiting mating portion 211, the side cover 2 is restricted from moving along the height direction of the housing body 1, thus fixing the side cover 2 to the side end of the housing body 1. It can be understood that the insertion portion 213 here, combined with the elastic portion 214 described above, enables the side cover 2 to be assembled to the housing body 1 along the height direction without the need for screws or other accessories, simplifying installation and saving costs.

[0057] like Figure 2 and Figure 7 As shown, in one embodiment of this utility model, the upper surface of the support platform 111 is also provided with an upwardly protruding water-blocking strip 1111. The water-blocking strip 1111 is provided on the side of the insertion hole 111a near the edge of the support platform 111 in the length direction of the housing assembly 100. During the use of the heater, there is a risk of water entering through the gap between the side cover 2 and the housing body 1. The water-blocking strip 1111 is used to guide water to both sides in the width direction to prevent water from entering and damaging components such as the main control board in the mounting groove 2a.

[0058] like Figure 2 , Figure 5 and Figure 7As shown, in one embodiment of this utility model, a first sliding buckle 22 is provided on the side of the side cover 2 facing the side end of the shell body 1. The first sliding buckle 22 is in the shape of a downwardly bent hook. A first mounting hole 12 is provided on the side end of the shell body 1 along the height direction of the shell assembly 100. The width of the first mounting hole 12 is narrowed from the middle section to both ends. When installing the side cover 2, the first sliding buckle 22 can be inserted from the middle section of the first mounting hole 12 firstly, and then the side cover 2 can be moved downward so that the first sliding buckle 22 is hooked onto the lower end of the first mounting hole 12.

[0059] In this embodiment, there are four first sliding buckles 22. The side end of the shell body 1 is provided with four first mounting holes 12. The first sliding buckles 22 are set in multiple ways to improve the strength of the connection structure. The first sliding buckles 22 are used to restrict the side cover 2 from moving along the length direction of the shell body 1. The first sliding buckles 22 are set on the side wall of the mounting groove 2a, which can also prevent the side wall of the side cover 2 from deforming. In some other embodiments of this utility model, the first sliding buckles 22 can be set to 2, 3, 5, 6, etc., and their number is not specifically limited.

[0060] In one embodiment of this utility model, the shell body 1 is mainly assembled from sheet metal parts. The sheet metal parts can be processed by stamping to form the bearing part 11 and the limiting part 112 in one step. Figure 7 It can be seen that the protrusion 1121 and the water-blocking strip 1111 are both stamped structures. It should be noted that the shell body 1 is generally used to install the heating element, and its material is usually metal, including but not limited to stainless steel and aluminum alloy, which is easy to process into thin plates and has a certain degree of plasticity. Combined with stamping technology, the thin plates can be manufactured into multiple sheet metal parts and assembled into the shell body 1. Of course, in some other embodiments of this utility model, the shell body 1 can also be made of composite materials (such as carbon fiber composite materials), which can also be formed using stamping technology. The choice of material can be based on actual needs.

[0061] In one embodiment of this utility model, the shell body 1 has a side cover 2 connected to each of its two sides along its length. Each side cover 2 has a handle groove for easy handling by the user. In some other embodiments of this utility model, the shell body 1 has a side cover 2 on only one end, or when the shell body 1 has multiple sides such as three or five, the number of side covers 2 can be set according to requirements.

[0062] In one embodiment of this utility model, the shell body 1 is made of metal, while the side cover 2 is made of plastic. Generally speaking, the plastic side cover 2 has a lower temperature rise, making it convenient for users to move the heater, and its manufacturing cost is also lower than that of metal. In some other embodiments of this utility model, the shell body 1 can also be made of heat-resistant plastic, composite materials, etc., while the side cover 2 can also be made of metal parts; the specific method is not limited.

[0063] like Figure 8 As shown, in one embodiment of this utility model, the shell body 1 includes an upper cover 13, a bottom cover 14, a front side plate 15, and a rear side plate 16. A supporting part 11 is disposed at the end of the upper cover 13. The upper cover 13, the bottom cover 14, the front side plate 15, and the rear side plate 16 are connected and enclosed to form a mounting cavity. This mounting cavity is used to install a heating element. The upper cover 13 and the bottom cover 14 have the same structure and are centrally symmetrically arranged. The front side plate 15 and the rear side plate 16 also have the same structure and are centrally symmetrically arranged. As can be seen from the above, the upper cover 13 and the bottom cover 14 have the same structure and can be manufactured using the same mold. They are shared parts. Furthermore, the front side plate 15 and the rear side plate 16 are also shared parts. This can reduce mold opening costs and reduce structural complexity, which is beneficial to reducing manufacturing costs.

[0064] like Figure 8 As shown, in one embodiment of this utility model, the shell body 1 further includes a left heat insulation plate 17 and a right heat insulation plate 18 disposed in the mounting cavity. The left heat insulation plate 17 and the right heat insulation plate 18 are respectively disposed at both ends of the mounting cavity to block heat. Furthermore, the left heat insulation plate 17 and the right heat insulation plate 18 have the same structure and are arranged in a centrally symmetrical manner. They are also common components. The two ends of the front side plate 15 are respectively connected to the two ends of the rear side plate 16 through the left heat insulation plate 17 and the right heat insulation plate 18.

[0065] Reference Figure 9 The left heat insulation plate 17 and the right heat insulation plate 18 each have threaded holes 18a at their four corners. The front side plate 15 and the rear side plate 16 each have corresponding snap-fit ​​positions and mating holes 15b. During installation, the left heat insulation plate 17 and the right heat insulation plate 18 can be fixed to the clamp first. Then, the front side plate 15 and the rear side plate 16 are placed on opposite sides of the left heat insulation plate 17 and the right heat insulation plate 18, and the left heat insulation plate 17 and the right heat insulation plate 18 are snapped into the snap-fit ​​positions.
