Detailed Description
Fig. 1 is a perspective view of a driving apparatus of an electric vehicle according to an embodiment of the present invention, which shows that a positioning pin at the bottom of an electric converter 120 is not inserted into a jack of a motor housing 110. Fig. 2 is a bottom view of the electrical converter and locating pin of fig. 1. Fig. 3 is a schematic top view of the motor housing of fig. 1. Referring to fig. 1 to 3, a driving apparatus 100 of an electric vehicle of the present embodiment includes a motor housing 110, an electrical converter 120, and two positioning pins 130a and 130 b. The motor housing 110 has four insertion holes 110a, 110b, 110c, 110 d. The two positioning pins 130a, 130b are connected to diagonal positions of the electric converter 120, respectively, and the two positioning pins 130a, 130b are adapted to be inserted into two insertion holes 110a, 110c of the four insertion holes 110a, 110b, 110c, 110d, respectively.
As described above, the motor housing 110 of the present embodiment is provided with the four insertion holes 110a, 110b, 110c, 110 d. Thus, depending on the shape of the electrical converter 120, the working position of the installer (e.g., working position a shown in fig. 2), and/or other installation conditions, the positions of the two positioning pins 130a, 130b that connect to a set of diagonal positions of the electrical converter 120 (e.g., upper-left and lower-right diagonal positions shown in fig. 2) that correspond to the positions of the two jacks 110a, 110c of the four jacks 110a, 110b, 110c, 110D may be selected such that the positioning pins 130a, 130b are positioned as shown in fig. 1 in a position that is visible from a particular installation condition and installation perspective (e.g., the installation perspective shown in fig. 1 that corresponds to working position a of fig. 2), i.e., a position that is visible from the same direction (e.g., first direction D1, indicated in fig. 2). As such, the length of the positioning pins 130a, 130B need not be excessively increased in order to make the installation perspective of the positioning pins 130a, 130B visible from both the first direction D1 in the operating position a and the second direction D2 (shown in fig. 2) in the operating position B, and the positioning pins 130a, 130B need only be visible from the first direction D1 in the operating position a. Accordingly, the electric converter 120 can be attached to the motor case 110 by the positioning pins 130a and 130b having a short length, thereby saving the manufacturing assembly cost and the transportation cost of the electric converter 120. The first direction D1 and the second direction D2 are, for example, horizontal directions, i.e., the first direction D1 and the second direction D2 are perpendicular to the extending direction of the positioning pins 130a, 130 b.
Fig. 4 is a schematic diagram of the electrical converter of fig. 2. Referring to fig. 2 and 4, more specifically, the electrical converter 120 of the present embodiment has four connection holes 120a, 120b, 120c, and 120 d. The positions of the four connection holes 120a, 120b, 120c, 120d of the electric converter 120 correspond to the positions of the four insertion holes 110a, 110b, 110c, 110d of the motor housing 110, respectively. The two positioning pins 130a and 130b are press-fitted into two connection holes 120a and 120c located at diagonal positions, respectively, of the four connection holes 120a, 120b, 120c, and 120d of the electric converter 120, and connected to the electric converter 120. Thus, the two positioning pins 130a, 130b may correspond to the positions of the two insertion holes 110a, 110c of the motor housing 110, respectively, as described above. The positioning pin is press-fitted to the electric converter as described above, so that the position of the positioning pin in the electric converter can be easily changed, and the electric converter can be applied to various mounting conditions. That is, the electric converter and the positioning pin have good mounting versatility and can reduce manufacturing costs.
Accordingly, the location at which the alignment pins 130a, 130b are coupled to the electrical converter 120 may vary depending on the shape of the electrical converter, the operating location of the installer, and/or other mounting conditions. The concrete description is as follows.
Fig. 5 shows the replacement of the electrical converter of fig. 1 with another electrical converter. Fig. 6 is a bottom view of the electrical converter and locating pin of fig. 5. In the embodiments shown in fig. 5 and 6, the positions of the two positioning pins 130a and 130B corresponding to the two insertion holes 110a and 110c in the four insertion holes 110a, 110B, 110c and 110D can be selected according to the shape of the electrical converter 120 ', the working position of the installer (the working position B shown in fig. 6) and/or other installation conditions, and a set of diagonal positions (the diagonal positions at the upper right and lower left as shown in fig. 6, namely, the positions of the connection holes 120B and 120D) for connecting the two positioning pins 130a and 130B to the electrical converter 120 ' can be selected according to the specific installation conditions and installation viewing angles (the installation viewing angle shown in fig. 5, which corresponds to the working position B in fig. 6) so that the positioning pins 130a and 130B are located at positions visible from this viewing angle as shown in fig. 5, namely, from the same direction (the first direction D1 ', which is marked in fig. 6). As such, the length of the positioning pins 130a, 130B need not be excessively increased in order to make the installation perspective of the positioning pins 130a, 130B visible from both the first direction D1 ' in the operating position B and the second direction D2 ' (shown in fig. 6) in the operating position a, and the positioning pins 130a, 130B need only be visible from the first direction D1 ' in the operating position B. The first direction D1 'and the second direction D2' are, for example, horizontal directions, i.e., the first direction D1 'and the second direction D2' are perpendicular to the extending direction of the positioning pins 130a, 130 b.
In summary, in the driving apparatus for an electric vehicle of the present invention, the motor housing is provided with four insertion holes. Thus, depending on the shape of the electrical converter, the working position of the installer and/or other installation conditions, the choice of connecting two locating pins to one set of diagonal positions of the electrical converter corresponding to two of the four receptacles or connecting two locating pins to another set of diagonal positions of the electrical converter corresponding to another two of the four receptacles allows the locating pins to be in a visible position in response to different installation conditions and installation perspectives. Thus, the length of the positioning pin does not need to be excessively increased in order to make the positioning pin visible at different installation visual angles. Accordingly, the driving apparatus of the electric vehicle of the present invention can mount the electric converter to the motor case through the positioning pin having a short length, thereby saving the manufacturing and assembling costs and the transportation costs of the electric converter. The electric converter can be provided with four connecting holes for selectively pressing and connecting two positioning pins, so that the positions of the positioning pins on the electric converter are easy to change, and the electric converter can be suitable for various installation conditions. That is, the electric converter and the positioning pin have good mounting versatility and can reduce manufacturing costs.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications or substitutions do not depart from the scope of the embodiments of the present invention, and the essence of the corresponding technical solutions is not disclosed.
