Embodiments of the present invention will be described below with reference to the drawings.

Example 1

The embodiment 1 of the utility model provides a casing.

Fig. 1 is an explanatory view of the case of the present embodiment, showing a case of viewing the case from one end side provided with a protruding part, and fig. 2 is another explanatory view of the case of the present embodiment, showing a case of viewing the case from the other end side.

As shown in fig. 1 and 2, the case 10 includes a housing 100 and a protruding member 200, and the protruding member 200 is partially embedded in the housing 100 and protrudes from an outer surface of the housing 100, wherein a groove 201 is provided on an outer surface of the protruding member 200, one end of the groove 201 is covered by the housing 100, and the other end of the groove 201 is exposed from the housing 100.

In the present embodiment, the housing 100 is a resin injection molded housing, and the protruding part 200 is integrally cast with the housing 100 by injection molding.

As is apparent from the above-described embodiment, since the groove 201 is provided on the outer surface of the protruding member 200, one end of the groove 201 is covered with the housing 100, and the other end of the groove 201 is exposed from the housing 100, when the housing 10 including the housing 100 and the protruding member 200 is integrally molded by the molding die, the gas in the molding die can be discharged from the groove 201 of the protruding member 200, and it is not necessary to provide the exhaust passage in the molding die, and therefore, after the housing is injection-molded by the resin, it is not necessary to clean the molding die to remove the resin of the exhaust passage, and the process can be saved.

As shown in fig. 1 and 2, the housing 10 is a motor housing, components of the motor, such as a rotating shaft, a stator, a rotor, and the like, may be provided inside the motor housing, and when the housing 10 as the motor housing is integrally molded, other components of the motor, such as the stator, may be provided in a mold, and when resin injection molding is performed, the housing 100, the protruding member, and the stator may be integrally molded. For example, the housing 10 may be a housing of another electromechanical device integrally formed by resin injection molding, which is not limited in this embodiment.

As shown in fig. 1 and 2, the protrusion member 200 is an interface for clamping and fixing a lead (not shown in fig. 1 and 2) which leads the lead from the inside to the outside of the housing 10, and for example, the lead may include a power supply line for energizing a coil, a power supply line for a drive control circuit, a signal line for transmitting a signal related to a rotation command from an external device, a signal line for transmitting a signal related to the rotation amount (number) of the rotor detected by a sensor to the external device, a ground line, and the like. The interface can lead the conducting wire out from the inside of the forming die to the outside during molding, protect the conducting wire from being crushed by the forming die, fix the position of the conducting wire and prevent the conducting wire from being broken when being pulled. However, the embodiment is not limited thereto, and the protrusion part 200 may be another part protruding from the outer surface of the casing 100 and integrally formed with the casing 100 by injection molding, for example, when the housing is another electromechanical device, the protrusion part may be a part having another function, such as a power outlet, etc.

In the present embodiment, for convenience of explanation, the case 10 is taken as a motor case and the protruding member 200 is taken as an interface, but it should be noted that the present embodiment is not limited thereto.

Fig. 3 to 14 show a plurality of examples of the groove portion of the protrusion member according to the embodiment of the present invention, and the following description is made separately.

Fig. 3 is an explanatory view of a protrusion member of the present embodiment, showing a case where the protrusion member is viewed from a side of a first protrusion member, fig. 4 is another explanatory view of the protrusion member shown in fig. 3, showing a case where the protrusion member is viewed from a side of a second protrusion member, fig. 5 is an explanatory view of the first protrusion member of the protrusion members shown in fig. 3 and 4, showing a case where the first protrusion member is viewed from a top of a side where a groove portion is provided of the first protrusion member, and fig. 6 is an explanatory view of the second protrusion member of the protrusion members shown in fig. 3 and 4, showing a case where the second protrusion member is viewed from a top of a side where the groove portion is provided of the second protrusion member.

As shown in fig. 3-6, in one or some embodiments, the protruding component 200 may have a first protruding component 202 and a second protruding component 203 that mate with each other, with the outer surfaces of the first and second protruding components 202 and 203 each formed with a groove 201. Thus, by forming the plurality of grooves 201 on the outer surface of the protrusion member 200, the gas inside the mold can be quickly exhausted to the outside. Further, it is possible to easily dispose a wire inside the protrusion part 200 and fix the wire by the first protrusion part 202 and the second protrusion part 203 which are fitted to each other, for example, fig. 3 and 4 show that a plurality of grooves 204 are formed in the first protrusion part 202, and the second protrusion part 203 covers the grooves 204 to form a structure for clamping and fixing the wire. However, the present embodiment is not limited thereto, and the protruding member itself may be an integrally formed structure, for example.

Fig. 3 to 6 show that the groove portions 201 are formed on both the upper surface (the surface of the first protrusion member 202 on which the groove portions 201 are provided) and the lower surface (the surface of the second protrusion member 203 on which the groove portions 201 are provided) of the protrusion member 200, but the embodiment is not limited thereto, and for example, the groove portions 201 may be formed only on the outer surface of the first protrusion member 202, or only on the outer surface of the second protrusion member 203, or the groove portions 201 may be formed on other surfaces, such as the side surfaces, of the protrusion member 200.

Fig. 3 to 6 show that two groove portions 201, that is, 4 groove portions 201, are formed on the outer surfaces of the first and second protruding parts 202 and 203, but the embodiment is not limited thereto, and the number of the groove portions 201 of the protruding part 200 may be other values, for example, 1, 2, 3, or 4 or more. The number and the position of the grooves may be set according to actual needs, and the present embodiment is not limited thereto.

In one or some embodiments, a resin is formed in the groove portion 201, thereby preventing contaminants (e.g., gas, water, oil stain) and the like outside the housing 10 from intruding into the interior of the housing 10 after the housing 10 is integrally molded. Further, the resin formed in the groove portion 201 may be formed at a later stage of the injection molding, at which time the gas inside the molding die has been substantially exhausted, and thus the resin formed in the groove portion 201 does not affect the gas exhaust from the groove portion 201.

In one or some embodiments, one end of the groove 201 extends at the outer surface of the protruding part 200 without reaching the edge of the outer surface. For example, as shown in fig. 3, the distance from the one end of the groove 201 to the edge of the first protrusion 202 is d1, as shown in fig. 4, the distance from the one end of the groove 201 to the edge of the second protrusion 203 is d2, and both d1 and d2 are greater than zero. This prevents the resin from leaking to the outside of the case 10 through the groove 201 when the case 10 is integrally molded by resin injection. In one or some embodiments, the other end of the slot 201 may extend to the edge of the protruding component 200. This allows the groove 201 to effectively communicate with the inside of the mold, thereby ensuring further gas discharge.

In one or some embodiments, as shown in fig. 5 to 6, the groove portion 201 includes a 1 st groove portion 2011 and a 2 nd groove portion 2012, the 1 st groove portion 2011 is disposed at one end of the protruding member 200 close to the inside of the housing (I-direction side of a dotted line L in fig. 5 and 6, the dotted line L is a boundary line between the inside and the outside of the housing, I-direction of the dotted line L is the inside of the housing, and O-direction of the dotted line L is the outside of the housing), the 2 nd groove portion 2012 is disposed at a position of the protruding member 200 away from the inside of the housing (O-direction side of the dotted line L in fig. 5 and 6) with respect to the 1 st groove portion 2011, and an extending direction of the 2 nd groove portion 2012 forms a predetermined angle. Fig. 5 and 6 show that the extending direction of the 1 st groove part 2011 and the extending direction of the 2 nd groove part 2012 form an angle of 180 degrees, but the present embodiment is not limited thereto, and the angle of the included angle between the extending direction of the 1 st groove part 2011 and the extending direction of the 2 nd groove part 2012 can also be other values.

In one or some embodiments, the extending direction of the 1 st groove part and the extending direction of the 2 nd groove part are parallel to the protruding direction of the protruding component relative to the housing, and as shown in fig. 5 and 6, the extending direction of the 1 st groove part 2011 and the extending direction of the 2 nd groove part 2012 are parallel to the direction in which the side edge 200a of the protruding component 200 is located (i.e., the protruding direction of the protruding component relative to the housing). However, the present embodiment is not limited to this, and for example, the 1 st groove 2011 and the 2 nd groove 2012 may extend in other directions, and the extending directions of the two may be different.

In one or some embodiments, the remainder of the channel 201 is not exposed to the shell, except for at least a portion of the 2 nd channel 2012. As shown in fig. 5 and 6, the portion of the 2 nd groove 2012 is located on the O direction side of the broken line L, and the remaining portion of the 2 nd groove 2012 and the 1 st groove 2011 are located on the I direction side of the broken line L, so that the groove is located as inside the housing as much as possible, which is advantageous in preventing the resin from leaking from the groove.

Fig. 7 to 14 are other examples of the groove portion of the protrusion member of the present embodiment, and the same contents as those of fig. 3 to 6 will not be described again, and only the difference between the groove portions of fig. 3 to 6 in fig. 7 to 14 will be described below.

As shown in fig. 7-10, in one or some embodiments, the trough 201 further includes a 3 rd trough 2013a, the 3 rd trough 2013a being located between the 1 st trough 2011 and the 2 nd trough 2012, one end of the 3 rd trough 2013a being connected to the 1 st trough 2011 and the other end of the 3 rd trough 2013a being connected to the 2 nd trough 2012. This makes it possible to form the groove portion into a labyrinth structure, and to prevent the resin from leaking out of the housing through the groove portion.

In one or some embodiments, as shown in fig. 7-10, the 1 st and 2 nd groove portions 2011, 2012 can extend parallel to the side 200a of the protruding component 200, and the 3 rd groove portion 2013a can extend parallel to the side 200b of the protruding component 200. However, the present embodiment is not limited to this, and for example, as shown in fig. 11 to 14, a projection of the 3 rd groove part 2013b in a direction perpendicular to the extending direction of the 1 st groove part 2011 and the 1 st groove part 2011 overlap each other, and as shown in fig. 14, a projection 2011a indicates a projection of the 3 rd groove part 2013b in the extending direction of the 1 st groove part 2011 and has a portion overlapping the 1 st groove part 2011. Thus, by forming the groove portion in a meandering structure, it is possible to further contribute to preventing the resin from leaking out of the housing through the groove portion. However, the present embodiment is not limited to this, and the extending direction of the 1 st groove 2011, the 2 nd groove 2012, and the 3 rd groove 2013a (2013b) may be in other ways as long as the groove 201 can be formed in a labyrinth structure.

Fig. 7 to 14 show a case where one 3 rd groove part 2013a (2013b) is provided between one 1 st groove part 2011 and one 2 nd groove part 2012, but the embodiment is not limited thereto, and two or more 3 rd groove parts may be provided between one 1 st groove part 2011 and one 2 nd groove part 2012, and the 3 rd groove parts may be connected in sequence.

In one or some embodiments, as shown in fig. 7 to 14, the rest of the groove 201 (the portions of the 1 st groove 2011, the 3 rd grooves 2013a/2013b, and the 2 nd groove 2012) is not exposed outside except that a portion of the 2 nd groove 2012 is exposed outside the housing (the O direction side of the dotted line L in fig. 9 to 10 and 13 to 14). This makes the groove portion as inside the housing as possible, which is advantageous for preventing the resin from leaking out of the groove portion.

According to the above embodiment, since the groove 201 is provided on the outer surface of the protruding member 200, one end of the groove 201 is covered with the case 100, and the other end of the groove 201 is exposed from the case 100, when the case 10 including the case 100 and the protruding member 200 is integrally molded by the molding die, the gas in the molding die can be discharged from the groove 201 of the protruding member 200, and the exhaust passage does not need to be provided in the molding die, and therefore, after the case is injection-molded by the resin, it is not necessary to clean the molding die to remove the resin of the exhaust passage, and the process can be saved.
