Description

Technical Field

[0001] The utility model relates to the field of motors, and in particular to a motor housing and a magnetic shoe circumferential positioning structure. Background Art

[0002] The circumferential positioning structure of the magnetic tile refers to the related structure for fixing the magnetic tile 2 inside the motor housing 1. After the magnetic tile 2 is circumferentially positioned, it is bonded with quick-drying glue, so that the housing can be put into use quickly. In the absence of circumferential fixing, the bonding between the magnetic tile 2 and the housing needs a long time (or additional processing steps are required to accelerate the glue curing process) before it can be used. Figure 1 and 2 As shown, the two ends of the two magnetic tiles 2 are elastically supported and positioned by an elastic bow-shaped member 3, and the two bow legs of the elastic bow-shaped member 3 provide circumferential fixing force, and the two bow legs respectively press against the side surfaces of the magnetic tile 2 to fix it. Summary of the invention

[0003] In order to solve the above problems, the first purpose of the utility model is to provide a motor housing, which has a positioning protrusion on the inner wall of the housing to position the magnetic tile on one side, so that the magnetic tile can be quickly installed, an elastic bow and installation process can be saved, costs can be saved, and the magnetic tile installation can be carried out more efficiently.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions:

[0005] A motor housing, wherein a housing chamber for mounting electronic magnetic tiles and an electronic rotor is constructed inside the housing; the two opposite side walls in the housing chamber are first side walls, and the other set of opposite side walls are second side walls, and the first side walls are magnetic tile mounting walls for fitting against the outer wall surfaces of the magnetic tiles; it is characterized in that: one and only one of the second side walls is provided with positioning protrusions for supporting one end of the magnetic tile corresponding to the first side walls on both sides.

[0006] The utility model adopts the above technical solution, which relates to a motor housing. In order to facilitate the positioning and installation of the magnetic tile, the motor housing is provided with positioning protrusions on only one side of the second side wall corresponding to the first side walls on both sides. During installation, the outer wall of the magnetic tile fits the first side wall, and one end of the magnetic tile rests on the positioning protrusion, while the other side can also be elastically positioned by an elastic bow-shaped member as used in the background technology.

[0007] Based on the above solution, a positioning protrusion is constructed on the inner wall of the housing to position the magnetic tile on one side, so that the magnetic tile can be quickly positioned. In this way, on the one hand, the circumferential positioning method can be retained to cooperate with the quick-drying adhesive bonding method, so that the housing can be quickly put into use; on the other hand, an elastic bow and installation process are saved, which saves costs and makes the installation of the magnetic tile more efficient.

[0008] In a specific embodiment, the positioning protrusion is constructed with a larger width at the root and a smaller width at the top, and the side wall of the positioning protrusion facing the first side wall is constructed as an inclined surface or an arc-shaped surface.

[0009] Preferably, the positioning protrusion is snap-fitted to the second side wall or is integrally formed by the concave portion of the second side wall, that is, the positioning protrusion in the solution is integrally formed with the housing, which is more convenient.

[0010] The second purpose of the utility model is to provide a circumferential positioning structure of a magnetic tile, comprising a motor housing and two magnetic tiles; characterized in that: the motor housing is the motor housing as described above, the two magnetic tiles are installed in the housing cavity and the outer end surfaces are attached to the first side wall; the same end of the two magnetic tiles respectively rests on two positioning protrusions, and the other ends of the two magnetic tiles are positioned by being stretched open by elastic bow parts.

[0011] This magnetic tile circumferential positioning structure adopts the motor housing recorded in the above scheme, and cooperates with an elastic bow-shaped member to realize the rapid positioning and installation of two magnetic tiles, saving costs and making the magnetic tile installation more efficient.

[0012] Preferably, the two ends of the magnetic tile are constructed as cut surfaces, which are used to abut against the positioning protrusion and the elastic bow. The end surface of the magnetic tile is constructed as a cut surface, which increases the contact area with the top surface of the positioning protrusion and the elastic bow, and avoids the end corner from being easily damaged.

[0013] In a specific implementation scheme, the elastic bow is U-shaped, and the elastic bow includes a first bow leg and a second bow leg. The first bow leg is vertically attached to the end surface of one side of the magnetic tile, and the second bow leg is inclined and elastically supported on the end surface of the other side of the magnetic tile.

[0025] Embodiment 1:

[0026] like Figure 3 As shown, the present embodiment relates to a motor housing, wherein a housing chamber 10 for mounting a magnetic tile 2 and an electronic rotor is constructed inside the motor housing 1. The two opposite side walls in the housing chamber 10 are the first side walls 11, and the other set of opposite side walls are the second side walls 12. The first side wall 11 is a magnetic tile mounting wall surface for fitting the outer wall surface of the magnetic tile 2. On one and only one side of the second side wall 12, corresponding to the first side walls 11 on both sides thereof, there are positioning protrusions 13 for supporting one end of the magnetic tile 2. In a specific implementation scheme, the positioning protrusion 13 is constructed with a large root width and a small top width, and the side wall of the positioning protrusion 13 facing the first side wall 11 is constructed as an inclined surface or an arc surface. Preferably, the positioning protrusion 13 is snapped onto the second side wall 12 or is integrally formed by the concave of the second side wall 12. That is, the positioning protrusion 13 in the scheme here is integrally formed with the housing, which is more convenient.

[0027] In order to facilitate the positioning and installation of the magnetic tile 2, the motor housing 1 is provided with positioning protrusions 13 only on the second side wall 12 on one side corresponding to the first side walls 11 on both sides. During installation, the outer wall surface of the magnetic tile 2 fits the first side wall 11, and one end of the magnetic tile 2 rests on the positioning protrusion 13, while the other side can also be elastically positioned by the elastic bow 3 used in the background technology. Based on the above scheme, a positioning protrusion 13 is constructed on the inner wall of the housing to position one side of the magnetic tile 2, so that the magnetic tile 2 can be quickly positioned. In this way, on the one hand, the circumferential positioning method combined with quick-drying glue bonding can be retained, so that the housing can be quickly put into use. On the other hand, an elastic bow 3 and an installation process are saved, which saves costs and makes the installation of the magnetic tile 2 more efficient.

[0028] It is particularly important to explain that the present solution requires that a positioning protrusion 13 be provided on one and only one side of the second side wall 12, while the elastic bow 3 is still retained for positioning on the other side, so as to adapt to the tolerance in the manufacturing process of the magnetic tile 2 and achieve elastic positioning.

[0029] Embodiment 2:

[0030] like Figures 4 to 6 As shown, the present embodiment relates to a magnetic tile circumferential positioning structure, comprising a motor housing 1 and two magnetic tiles 2. The motor housing 1 is the motor housing 1 as described above, and the two magnetic tiles 2 are installed in the housing chamber 10 and the outer end faces are attached to the first side wall 11. The same end of the two magnetic tiles 2 respectively abuts against two positioning protrusions 13, and the other ends of the two magnetic tiles 2 are stretched and positioned by elastic bow members 3. This magnetic tile circumferential positioning structure adopts the motor housing 1 recorded in the scheme of embodiment 1, and cooperates with an elastic bow member 3 to realize the rapid positioning and installation of the two magnetic tiles 2, saving costs and making the installation of the magnetic tiles 2 more efficient.

[0031] Preferably, the two ends of the magnetic tile 2 are constructed as cut surfaces, which are used to abut against the positioning protrusion 13 and the elastic bow 3. The end surface of the magnetic tile 2 is constructed as a cut surface, which, on the one hand, increases the contact area with the top surface of the positioning protrusion 13 and the elastic bow 3, and on the other hand, can avoid the end corner from being easily damaged.

[0032] In a specific implementation scheme, the elastic bow member 3 is U-shaped, and the elastic bow member 3 includes a first bow leg 31 and a second bow leg 32. The first bow leg 31 is vertically attached to the end surface of the magnetic tile 2 on one side, and the second bow leg 32 is inclined and elastically supported on the end surface of the magnetic tile 2 on the other side.
