Description

Technical Field

[0001] The present disclosure relates to a mounting stand for a generator of a vehicle. Background Art

[0002] Generators are used in vehicles to power electrical devices in the vehicle and charge the vehicle's battery. The generator needs to be connected to the crankshaft of the vehicle engine and the pulleys of other devices (such as compressors) through belts in the vehicle. Since the connected belts need to be tensioned for normal use, a tensioning pulley is usually installed at the power input end of the generator.

[0003] In the actual assembly process of the vehicle, the tensioning wheel is usually pre-installed on the generator in a pre-installation line outside the main production line. This pre-installation process is generally performed on an independent mounting table. Due to the irregular shape and heavy weight of the generator itself, and the installation of the tensioning wheel requires a certain torque tightening operation, when installing the tensioning wheel on the mounting table, it is necessary to first position the generator relative to the mounting table to prevent the generator from accidentally moving when installing the tensioning wheel.

[0004] In the prior art, positioning the generator relative to the mounting platform is usually achieved by using a positioning device fixed to the mounting platform. The positioning device includes a plurality of positioning pins with fixed positions. The generator is fixed and positioned relative to the mounting platform by engaging the plurality of positioning pins with mounting holes of the generator (the mounting holes are used to subsequently tighten and fix the generator to the vehicle engine).

[0005] However, in the production line, it is often necessary to assemble multiple models, and the positions of the mounting holes of the generators used in different models may be different. For example, the new generation 48V mild hybrid generator used in a BMW GX8 series model has mounting holes in different positions compared to the original generator, and the mounting holes are usually located at different positions along the longitudinal axis of the generator (that is, with a variable height position). In order to ensure that the new and old models are produced on the same line, it is necessary to quickly switch the positioning pins to ensure the pre-installation of the corresponding models. Therefore, in the prior art, in order to adapt to the pre-installation of generators of different models, different mounting platforms adapted to different generators must be set, wherein different mounting platforms are fixed with different positioning devices, and the positions of the positioning pins included in each positioning device are different, so as to engage at least one mounting hole at different positions of different generators. The provision of multiple positioning devices greatly increases the production cost. In addition, the simultaneous arrangement of multiple mounting platforms also occupies a large space of the production line, which further increases the production cost. Utility Model Content

[0011] In one embodiment, the generator has a mounting end for mounting a tensioning wheel and an opposite bottom end, and the mounting platform further comprises a support base fixed on the platform surface, the support base supports the bottom end of the generator at the center.

[0012] In one embodiment, the rotating portion is rotatable about a vertical longitudinal axis.

[0030] First reference Figure 3 , Figure 3 A schematic perspective view of a generator 2000 for a vehicle is shown that may be positioned using a mounting station according to the present disclosure.

[0031] The generator 2000 extends in a longitudinal direction and has a mounting end 2100 for mounting a tensioning wheel and an opposite bottom end 2200. By suitable connection, such as Figure 4 As schematically shown, the tensioner assembly 4000 is to be mounted to the mounting end 2100 of the generator 2000 .

[0032] The generator 2000 also has a first mounting hole 2300 and a second mounting hole 2400 for mounting the generator 2000 to the engine. The first mounting hole 2300 is a uniform mounting hole, i.e., a mounting hole at the same position for different generators. The second mounting hole 2400 varies depending on the type of generator, and the second mounting holes of different types of generators may have different height positions. In the present disclosure, having a different height position means that for different types of generators, the second mounting hole 2400 has different positions along the longitudinal axis of the generator.

[0033] The generator 2000 may further have an additional third mounting hole (not shown). The third mounting hole is aligned with the first mounting hole in the longitudinal direction of the generator 2000. The third mounting hole is also a unified mounting hole.

[0034] The following will Figure 3 The generator 2000 in FIG. 1 is used as an example to describe the mounting station 1000 for a generator of a vehicle according to the present disclosure, but those skilled in the art may understand that the mounting station 1000 may also be used for a generator different from the generator 2000 .

[0035] refer to Figure 1 , which shows a mounting stand 1000 for a generator for a vehicle according to the present disclosure.

[0036] The mounting table 1000 includes a table top 100 and a support assembly 200 .

[0037] The table top 100 has a flat upper surface for supporting other components of the mounting table 1000 and the generator 2000. The table top 100 may include a connection hole 110 for connecting the mounting table 1000. By means of the connection hole 110 and the engagement of corresponding fasteners (such as bolts, screws, etc.), the table top 100 can be connected to the surface of other equipment to form an operating surface. In other embodiments, the table top 100 can be directly connected to the leg portion through the connection hole 110.

[0038] The bracket assembly 200 is used to cooperate with the mounting hole of the generator 2000 to position the generator 2000. The bracket assembly 200 includes a first support column 210 and a second support column 250.

[0039] The first support column 210 is used to position the first mounting hole 2300 having a fixed position of the generator 2000. The first support column 210 extends upward along a vertical longitudinal axis from the table top 100 of the mounting table 1000. The first support column 210 has a first end connected to the table top 100 and an opposite second end.

[0040] The first pillar 210 has a first protrusion 211. The first protrusion 211 may extend perpendicularly to the longitudinal axis of the first pillar 210 and may be substantially plate-shaped. The first protrusion 211 has a protruding first positioning pin 213. For example, the first positioning pin 213 may extend vertically upward from the first protrusion 211. When positioning the generator 2000, the first positioning pin 213 passes through the first mounting hole 2300 of the generator 2000, thereby engaging the first mounting hole 2300 of the generator 2000.

[0041] The first protrusion 211 may have a horizontal abutment surface 212. When positioning the generator 2000, the first positioning pin 213 passes through the first mounting hole 2300 of the generator 2000 until the abutment surface 212 of the first protrusion 211 abuts against the generator 2000, so as to provide additional support to the generator 2000.

[0042] exist Figure 1 In the example shown, the first protrusion 211 is located at the second end of the first pillar 210, but it is understandable that the height of the first pillar 210 can be changed as needed, and the position of the first protrusion 211 can also be set at other positions on the first pillar 210 according to the position of the mounting hole of the generator to be positioned.

[0043] The first pillar 210 may also have a third protrusion 214. The third protrusion 214 may extend parallel to the first protrusion 211. The third protrusion 214 has a protruding third positioning pin 216. For example, the third positioning pin 216 may extend vertically upward from the third protrusion 214. The third positioning pin 216 is aligned with the first positioning pin 213 along the vertical longitudinal axis. When positioning the generator, the third positioning pin 216 passes through the third mounting hole of the generator 2000 with a fixed position. By providing the third positioning pin 216 engaged with the third mounting hole of the generator, the positioning of the generator 2000 by the mounting table 1000 is made more stable.

[0044] The third protrusion 214 may also have a horizontal abutment surface (not shown). When positioning the generator 2000 , the third positioning pin 216 passes through the third mounting hole of the generator 2000 until the abutment surface 212 of the third protrusion 214 abuts the generator 2000 to provide additional support for the generator 2000 .

[0045] exist Figure 1 It is shown that the third protrusion 214 extends all the way to the table 100 , but it is understandable that the third protrusion 214 can be designed into other shapes as needed. For example, the third protrusion 214 can be roughly plate-shaped like the first protrusion 211 .

[0046] The second support 250 is used to position the second mounting hole 2400 with a variable height position of the generator 2000. The second support 250 also extends upward along a vertical longitudinal axis from the table 100 of the mounting table 1000. The second support 210 has a first end connected to the table 100 and an opposite second end.

[0047] A rotatable rotating part 300 is disposed on the second pillar 250. By rotating, the rotating part 300 provides different positioning pins adapted to the second mounting holes 2400 with different height positions of different generators 2000. In the present disclosure, the rotating part 300 is shown to rotate around a vertical longitudinal axis, but it can be understood that the rotating part can also be configured to rotate around another axis.

[0048] exist Figure 1 In the example shown, the rotating part 300 is rotatably mounted to the second pillar by a rotating shaft 310. The rotating shaft 310 passes through a first central hole of the rotating part 300 and a second central hole of the second pillar 250 aligned with the first central hole along the vertical longitudinal axis, whereby the rotating part 300 can rotate around the rotating shaft 310 and around the vertical longitudinal axis.

[0049] Those skilled in the art will appreciate that other forms may be used to rotatably mount the rotating portion 300 to the second pillar 250 without departing from the scope of the present disclosure. For example, the rotating portion 300 may be configured to have a bottom end that can be rotatably inserted into the second pillar 250 to allow the rotating portion 300 to rotate.

[0050] See also Figure 1 and Figure 2 The rotating part 300 may have a substantially cylindrical shape. The rotating part 300 has at least two second protrusions 320. The protrusions 320 extend outward from the outer surface of the rotating part 300. For example, the protrusions 320 may extend outward from the outer surface of the rotating part 300 along the radial direction of the rotating part 300. Figure 2, at least two second protrusions 320 are spaced apart from each other in the circumferential direction of the rotating part 300 so that the second protrusions 320 do not interfere with each other. Each of the at least two second protrusions 320 is positioned at a different height along the vertical longitudinal axis. Each second protrusion 320 has a second positioning pin 330 extending from the second protrusion 320. For example, the second positioning pin 330 can extend vertically upward from the second protrusion 320.

[0051] The second protrusions 320 and the second positioning pins 330 assigned thereto at different heights are selectively rotated to the engagement position by the rotation of the rotating part 300. At the engagement position, the second protrusions 320 can pass through the second mounting holes 2400 of the generator 2000 to engage the second mounting holes 2400. Thus, by rotating different second positioning pins 330 to the engagement position, the second mounting holes 2400 of different generators 2000 with different height positions can be adapted.

[0052] Each second protrusion 320 may have a horizontal abutment surface 340. When positioning the generator 2000, the second positioning pin 330 passes through the second mounting hole 2400 of the generator 2000 until the abutment surface 340 of the second protrusion 320 abuts against the generator 2000, so as to provide additional support to the generator 2000.

[0053] In the example of the present disclosure, the rotating part 300 is shown to have three second protrusions 320, but it is understood that the number of the second protrusions 320 can be changed to adapt to more types of generators. For example, the rotating part 300 can have two, four, five, etc. second protrusions 320, wherein each second protrusion 320 is located at a different height along the vertical longitudinal axis.

[0054] The second support 250 may also include a locking device. The locking device is used to lock the rotating part 300 when any one of the at least two second protrusions 320 rotates to the engagement position to prevent the corresponding second protrusion 320 from rotating away from the engagement position, thereby facilitating the operation of positioning the generator 2000. The locking device may take various forms. For example, the locking device may be a ball pin arranged on the rotating shaft 310 and aligned with the engagement position; the ball pin may be engaged in any one of a plurality of corresponding recesses arranged on the inner surface of the rotating part 300; each recess corresponds to a second protrusion 320.

[0055] refer to Figure 1 and Figure 2, the support assembly 200 may include a connection portion 270 connecting the first support 210 and the second support 250 together. The connection portion 270 is used to make the overall structure of the support assembly 200 more stable. The connection portion 270 may be a separate component connected to the first support 210 and the second support 250 by fasteners, gluing, welding, etc. The connection portion 270 may also be integrally formed with one or both of the first support 210 and the second support 250.

[0056] The support assembly 200 may further include a contoured block 290. The contoured block 290 has a back surface attached to the first support 210, the second support 250, and the connecting portion 270 and an opposing contoured surface. The back surface of the contoured block 290 is attached to the first support 210, the second support 250, and the connecting portion 270 by fasteners, gluing, welding, etc. The contoured surface of the contoured block 290 is configured to engage and match a portion of the outer surface of the generator 2000 to provide a more stable support for the generator 2000 and prevent the generator 2000 from being knocked when positioned.

[0057] exist Figure 1 In the example shown, the contour block 290 is configured to cover the third protrusion 214 and the third positioning pin 216 extends through the contoured surface. However, it is understood that the contour block 290 can be configured in other forms. For example, the contour block 290 can be configured not to cover the third protrusion 214.

[0058] The mounting table 1000 may include a support base 400 fixed to the table top 100. Figure 1 and Figure 2 As shown, the support base 400 may be in the form of a cylinder having a central hole. The support base 400 is used to support the bottom end 2200 of the generator 2000 at the center so as to stably support the generator 200 when the bottom end 2200 of the generator 2000 cannot be stably placed due to the presence of a vertically downward protruding portion around the bottom end 2200 of the generator 2000.

[0059] Figure 5 2000 of a vehicle is exemplarily shown as a perspective view when the generator 2000 of the vehicle is positioned on the mounting station 1000 according to the present disclosure. Figure 5 As shown, the generator 2000 is supported by the support table 400. A portion of the outer surface of the generator 2000 engages the contour block 290. The first mounting hole 2300 of the generator 2000 engages with the first locating pin 213 and optionally the third mounting hole of the generator 2000 engages with the third locating pin 216, while the second mounting hole 2400 of the generator 2000 engages with one of the at least two second locating pins 330.

[0060] By using the rotating table 300 of the mounting table 1000 according to the present disclosure, the second protrusion 320 located at different heights and its second positioning pin 330 are allowed to be selectively rotated to the engagement position to engage the second mounting hole 2400 with a variable height position of the generator 2000, thereby achieving the positioning of multiple generators using only one mounting table.
