As described in the background art, the original old product is assembled by a perfect operation instruction book, so as to instruct staff how to pre-assemble some components first, and then assemble the pre-assembled components into the whole machine in sequence. Because old product model production is more mature perfect, newly-increased function on the old product, the wire, spare part are moved to the new wiring of adding on original old product, and pencil drunkenness can move the assembly and form great puzzlement, consequently need redesign assembly order to solve the fixed problem of pencil earlier, install again. This also results in that after the new function is added, the assembly of the whole new model is obviously changed relative to the old model, thereby affecting the assembly efficiency.

In view of the above problems, referring to fig. 1 to 4, an embodiment of the present application provides a mounting structure 100 that can be used in an electric heater. The mounting structure 100 includes a body 10 and a first limiting member 30. The body 10 is formed with a mounting location 11, the mounting location 11 being used for mounting a new component 210. The first limiting member 30 is disposed on the body 10 and disposed along a set routing direction, and is configured to form a limiting fit with the wire harness 230 connected to the added component 210.

The mounting structure 100 may be, but is not limited to, a front housing, a rear housing of the cabinet of the electric heater 200, or other structural mounting plates provided within the cabinet, etc.

The newly added parts 210, that is, the parts corresponding to the newly added functions, may be, but not limited to, microphones 211, speakers 212, cameras, etc., and it is understood that the number and shape of the mounting locations 11 are adapted to the number and shape of the newly added parts 210.

The installation structure 100 comprises at least one first limiting piece 30, all the first limiting pieces 30 are arranged along a set routing direction, so that a wire harness 230 in limiting fit with the first limiting pieces can travel according to the set routing direction, the final routing path of the wire harness 230 meets the requirement, and the wire harness 230 cannot randomly move under the limiting of the first limiting pieces 30. The first limiting member 30 may be in a limiting fit with the wire harness 230, such as, but not limited to, clamping the wire harness 230, forming a routing hole through which the wire harness 230 passes, or bonding the wire harness 230.

When the number of the first limiting members 30 is one, the arrangement along the set routing direction means that the first limiting members 30 generate a constraint in a specific direction on the wire harness 230 that forms a limiting fit with the first limiting members, and a corresponding implementation manner may be to clamp the wire harness 230 in the specific direction, make the routing hole of the first limiting members 30 face the specific direction or adhere the wire harness 230 along the specific direction, and so on. When the number of the first limiting members 30 is plural, the arrangement along the set routing direction further includes a plurality of first limiting members 30 arranged at set positions so as to be connected in series to form a set routing path, in addition to the constraint of each first limiting member 30 in a specific direction on the wire harness 230 with which it forms a limit fit. When the mounting structure 100 has a plurality of wire harnesses 230 thereon, at least a portion of the wire harnesses 230 form a positive engagement with the first limiting member 30, and are constrained.

The mounting structure 100 can be preloaded with the new component 210 and fix the wire harness 230 by the first stopper 30. Thus, after the new component 210 is mounted on the body 10, the wire harness 230 thereof is constrained by the first limiting member 30 and cannot be moved at will, so that the assembly between the subsequent components is not disturbed. When the whole machine is assembled, the assembly sequence of the old machine can be used, and the procedure of installing the newly added part 210 to form the assembly is only needed to be added between the original assembly sequences, so that the assembly sequence does not need to be adjusted in a large range, and the assembly efficiency is improved. In addition, during assembly, an operator can realize blind assembly of the wire harness 230 by locating the first limiting piece 30, and the wire harness 230 can be assembled and connected more accurately under the guidance of the first limiting piece 30.

In some embodiments, the body 10 is further configured with a wire via 13, the wire via 13 being configured for the wire harness 230 to pass from one side of the body 10 to the opposite side of the body 10.

The wire through hole 13 is used for the wire harness 230 to pass through the body 10, one end of the wire harness 230 is connected to the added part 210, and the other end forms the plug-in terminal 231. The mounting location 11 on the body 10 may be configured on the same side of the body 10, and the plug-in terminal 231 of the wire harness 230 may reach the other side of the body 10 through the wire through hole 13.

Thus, when the assembly is sequentially performed, the insertion terminals 231 of the wire harness 230 can pass through the body 10 through the wire passing holes 13 after the additional parts 210 are mounted on the body 10. The whole machine can be assembled in sequence continuously, and when the subsequently installed components are installed, the plug-in terminals 231 are connected with the plug-in terminals, so that the original component installation sequence and the installation position 11 are not required to be changed. In addition, the wire passing hole 13 itself can also exert a restraining effect on the wire harness 230 passing therethrough.

The mounting structure 100 may be a front shell, the component to be mounted subsequently may be a control board assembly 250, and the front surface of the front shell forms the mounting position 11 as an example, and the control board assembly 250 is mounted on the back surface of the front shell and may be connected with the front shell through screws. The new component 210 is mounted on the front surface of the front case, and the plug-in terminal 231 of the wire harness 230 can pass through the wire passing hole 13 to be connected with the control board assembly 250 when mounted.

Referring to fig. 5, in some embodiments, the first limiting member 30 includes a first portion 31 and a second portion 33, and a clamping gap for clamping the wire harness 230 is formed between the first portion 31 and the second portion 33.

As can be appreciated, the wire harness 230 is clamped into the clamping gap and clamped by the first limiting member 30 to form a limiting fit. The wire harness 230 forms an interference fit with the first stopper 30, and the first portion 31 and the second portion 33 may form an arc-shaped guide structure at the edge of the clamping gap.

Thus, the wire harness 230 can form a spacing fit with the first spacing member 30 by being clamped between the first portion 31 and the second portion 33. Such a harness 230 is simple to install and is easier to align, facilitating blind-fitting operations.

Further, the wire diameter of the wire harness 230 is K, and the width of the clamping gap is L, and then L is more than or equal to 0.65K and less than or equal to 0.85K.

It will be appreciated that the width of the clamping gap, i.e. the spacing between the first portion 31 and the second portion 33, is less than the wire diameter of the wire harness 230 such that the first stop 30 forms an interference fit with the wire harness 230. Wherein the wire diameter of the wire harness 230 is the outer diameter of the wire harness 230.

Specifically, the width L of the clamping gap may be, but is not limited to, 0.65K, 0.70K, 0.75K, 0.8K, 0.85K.

Thus, after the wire harness 230 is clamped into the clamping gap, the wire harness can be firmly clamped by the first limiting piece 30, and the possibility of occurrence of movement of the wire harness is reduced.

Referring to fig. 6, in some embodiments, the mounting structure 100 further includes a second limiting member 50, where the second limiting member 50 is disposed around the mounting location 11 and is used for limiting a new component 210 disposed in the mounting location 11.

The second limiting member 50 may be, but not limited to, a plurality of limiting ribs, coamings, etc., and is disposed around the periphery of the mounting location 11, and when the number of the mounting locations 11 is plural, at least part of the periphery of the mounting locations 11 is provided with the second limiting member 50, so as to limit the newly added part 210 in the mounting locations 11.

In this way, after the new component 210 is mounted on the mounting position 11, the new component 210 is constrained by the second limiting member 50 and cannot move at will, which is helpful for improving the mounting stability of the new component 210 and facilitating the subsequent assembly process.

Further, the mounting structure 100 is formed with at least one mounting position 11, the second limiting members 50 are disposed on the peripheral sides of all the mounting positions 11, and at least part of the second limiting members 50 corresponding to the mounting positions 11 are in interference fit with the newly added parts 210 therein.

Thus, the second limiting member 50 is in interference fit with the newly-added part 210 in the mounting position 11, and when the mounting is performed, the newly-added part 210 is forcibly pressed into the mounting position 11, and the newly-added part 210 is clamped by the second limiting member 50 and cannot be freely separated from the mounting position 11.

Further, the second limiting member 50 is composed of a plurality of limiting ribs, the size P (in mm) of the surrounding area of the limiting ribs, the external dimension of the newly added part 210 is Q (in mm), and then p=q- (0.3 mm-0.5 mm), which corresponds to an interference of 0.3 mm-0.5 mm.

The dimension P of the limiting rib enclosing region may be, but not limited to, a width, a length, a diameter, etc., and it is understood that the external dimension Q of the newly added part 210 is a width, a length, or a diameter, respectively.

Specifically, the added component 210 includes a microphone 211, a second limiting member 50 is disposed on a peripheral side of the mounting position 11 where the microphone 211 is mounted, and the microphone 211 and the second limiting member 50 are in interference fit.

In some embodiments, body 10 is further configured with a clearance space 15, and clearance space 15 is used to clear the structure of other components within electric heater 200 for assembly.

In some embodiments, the first limiting member 30 is integrally formed on the body 10. Similarly, the second limiting member 50 may be integrally formed on the body 10.

The first limiting member 30 and the second limiting member 50 are integrally formed with the body 10, which means that they can be manufactured by integral casting with the body 10.

Thus, only the old product mold is changed, and the mold for producing the new product mounting structure 100 can be obtained, which is beneficial to reducing the manufacturing cost.

Referring to fig. 7 and 8, the present application further provides an electric heater 200, including the above-mentioned mounting structure 100.

In one embodiment, the electric heater 200 includes a new component 210, the new component 210 includes a microphone 211 and a speaker 212, and the microphone 211 and the speaker 212 can be used to implement voice interaction. Accordingly, the mounting structure 100 is formed with two mounting locations 11 for mounting the microphone 211 and the speaker 212, respectively.

Referring to fig. 9 to 14, in some embodiments, the mounting structure 100 is a front shell, the electric heater 200 further includes a mesh cover 270, and the mesh cover 270 is disposed on a side of the mounting structure 100 forming the mounting location 11 and presses on the added part 210 in the mounting location 11. One of the mounting structure 100 and the mesh enclosure 270 forms the second positioning hole 17, and the other forms the positioning rib 275 that mates with the second positioning hole 17.

The mesh enclosure 270 is disposed on the front surface of the mounting structure 100, and is configured to press on the newly added component 210 in the mounting position 11 after the mesh enclosure is connected to the mounting structure 100. For the microphone 211 and the speaker 212, the mesh cover 270 is provided with a sound pickup hole 271 and a speaker hole 273, respectively.

Specifically, the mounting structure 100 may have the second positioning hole 17 formed at a position of the body 10 near the lower end, and the mesh cover 270 has the positioning rib 275 formed at the bottom. During installation, the mesh enclosure 270 is inserted into the second positioning hole 17 of the installation structure 100 through the positioning ribs 275 to complete pre-fixing, then the two pre-fixing parts are turned over, and the mesh enclosure 270 is fixed on the installation structure 100 through the screw positions 290 at the back of the mesh enclosure 270 by using screws.

In this way, the new component 210 can be effectively fixed after the installation is completed by pressing down the mesh enclosure 270.

Referring to fig. 15 and 16, in some embodiments, the electric heater 200 further includes a control board assembly 250, where the control board assembly 250 is connected to the body 10, and a wire buckle 251 is formed on a side facing the body 10, and the wire buckle 251 is used for fixing the wire harness 230.

Taking the mounting structure 100 with the front side forming the mounting position 11 as an example, the control board assembly 250 is mounted on the back side of the mounting structure 100, and the wire buckle 251 is formed on the side of the control board assembly 250 facing the mounting structure 100.

Thus, the wire harness 230 can be fixed with the control board assembly 250 through the wire buckle 251, so that the wire harness 230 is prevented from randomly moving when the control board assembly 250 is installed.

Further, one of the mounting structure 100 and the control board assembly 250 is formed with a positioning post 19, and the other is formed with a first positioning hole 253 that mates with the positioning post 19.

Specifically, the mounting structure 100 is formed with a positioning post 19 and the control board assembly 250 is formed with a first positioning hole 253.

In this way, the control board assembly 250 passes through the first positioning hole 253 and the positioning post 19 of the mounting structure 100 to complete pre-fixing, and then screws the control board assembly 250 and the mounting structure 100 through the screw position 290.

The electric heater 200 comprises the following assembly steps: the loudspeaker 212 and the microphone 211 are preloaded in the installation position 11 on the front shell, and the newly added part 210 is limited and fixed through the second limiting piece 50; a wire harness 230 connected with the microphone 211 is clamped into the first limiting piece 30 on the front shell; a wire harness 230 connecting the microphone 211 and the speaker 212 passes through the wire passing hole 13 on the front case; the mesh cover 270 is inserted into the second positioning hole 17 of the front shell through the positioning ribs 275 to finish pre-fixing, then the mesh cover 270 and the second positioning hole are turned over, and the mesh cover 270 is fixed on the front shell through the screw position 290 at the back of the mesh cover 270 by using screws so as to cover the loudspeaker 212 and the microphone 211; the wire harness 230 passing through the wire through hole 13 of the front shell in the previous step is firstly fixed by the wire buckle 251 on the control panel assembly 250 so as to prevent the wire harness from randomly moving when the control panel assembly 250 is installed; the control panel assembly is pre-fixed on the front shell by penetrating the first positioning hole 253 through the positioning column 19 on the front shell, and the control panel assembly 250 is fixed with the mounting structure 100 by screwing the screw position 290, so that the assembly of the newly added part 210 and the wire harness 230 is completed and other assembly procedures are continued.
