Description

Split type motor support, guide limiting device, motor, water wiping system and vehicle

Technical Field

The utility model relates to a split type motor support, guide stop device, motor, scrape water system and vehicle. Particularly, the present invention relates to a modular or split motor mount in a wiper system and a guide and limit device, such as a slide groove, associated with the split motor mount.

Background

Generally, a wiper blade is used to remove foreign matter, rain, and snow while an automobile is traveling, and to ensure a driver's forward field of vision. In a conventional wiper blade, a motor drives a link device connected by a wiper arm to reciprocate in a fan shape.

Referring to fig. 1 and 2, there are shown schematic views of a mini-bracket and a large punch motor bracket, respectively, according to the prior art.

In a conventional wiper blade structure, a pair of metal back plates are coupled to a rubber wiper blade, and the back plates are supported by a plurality of yoke members connected to each other by a plurality of support rods. Generally speaking, there are two main types of motor supports in a wiper system. The first is a mini-stent 91 or micro-stent (see FIG. 1 for details). A motor mounting pin 92 is configured at the motor itself for mounting the motor to the body of the vehicle. Such a micro-bracket is small, which results in material savings, but the mounting pin cannot fit all bodies, because space distances and the characteristics of the wiper system are also taken into account.

The second is a large ram motor bracket 93 (see fig. 2 for details). The large punch motor bracket mounting pin 94 is in the motor bracket. This type of support can be adapted to all vehicle bodies. However, one side of this type of bracket is fixed in the motor by 3 to 4 screws, and thus the other side (the side where the pin is mounted) is like a cantilever. When the screw is tightened in a product line, the motor bracket is deformed due to the interference of about 0.9mm between the motor bracket and the connecting pipe and the influence of tightening torque, and the manufacturing tolerance of the mounting pin is larger than the standard tolerance required by a drawing. This results in a production line that takes a significant amount of time to adjust tolerances to meet drawing tolerance requirements. If the adjustment is not successful, a large amount of waste is produced. This requires the motor mount to be trimmed in order to be able to adapt the body again. But this can result in retooling costs and lost project development time.

In current water scraping systems, most motor brackets are of a fixed design and are difficult to adjust if the cantilevered end of the motor bracket deforms when the bolt is tightened. In all current designs, the amount of deflection of the cantilevered end after the motor bracket is bolted down takes a significant amount of time to adjust or trim the mold. In addition, no wiper system currently uses a motor bracket that is assembled in combination.

CN103158674B discloses a wiper device for a vehicle, which may comprise: a lower pivot shaft integrally coupled at a lower end thereof to a connection lever rotatable by a force transmitted from a wiper motor to rotate the lower pivot shaft, wherein the lower pivot shaft includes a coupling protrusion integrally protruding from an upper end thereof; an upper pivot shaft seated on an upper surface of the lower pivot shaft, the upper pivot shaft having a coupling recess integrally formed on a lower surface thereof so as to selectively fit the coupling protrusion therein, wherein an arm head may be integrally coupled to an upper end of the upper pivot shaft protruding on a cowl panel; and a shaft bracket fixed to the cowl panel while engaging therein a coupling portion between the lower pivot shaft and the upper pivot shaft.

Therefore, the following detailed description and the accompanying drawings are merely illustrative of the technical solutions of the present invention, and should not be considered as limiting or restricting the technical solutions of the present invention in their entirety or in any other way.

The terms of orientation of up, down, left, right, front, back, top, bottom, and the like referred to or may be referred to in this specification are defined relative to the configuration shown in the drawings, and are relative terms, and thus may be changed correspondingly according to the position and the use state of the device. Therefore, these and other directional terms should not be construed as limiting terms. Furthermore, the terms "first," "second," "third," and the like are used for descriptive and descriptive purposes only and not for purposes of indication or implication as to the relative importance of the respective components.

Referring to fig. 3 to 4, there are shown schematic views of an embodiment of a split motor bracket 3 and a guide and stop device 1 according to the present invention, respectively. The split motor bracket 3 is used for assembling a motor of a wiper system of a vehicle, the wiper system having the motor and a connecting pipe 4 for connecting the motor, the motor having a motor housing 2, wherein the split motor bracket 3 includes a first sub-motor bracket 31 and a second sub-motor bracket 32, wherein the first sub-motor bracket 31 is used for being fixed on the motor housing 2 and for limiting the connecting pipe 4, the second sub-motor bracket 32 is used for being fixed on the motor housing 2, and one end of the second sub-motor bracket 32 is used for being connected with the first sub-motor bracket 31, and the other end of the second sub-motor bracket 32 is used for being connected to a body of the vehicle. The guide and limit device 1 is used for the split motor mount 3 described above, wherein the guide and limit device 1 is arranged on the motor housing 2 (for example on a motor gear box of the motor), and the second sub-motor mount 32 is fitted to the motor housing 2 via the guide and limit device 1 and is held in a fixed position relative to the motor housing 2.

It is to be understood that the motor is used for driving a wiper arm or wiper arm lever of the wiper system in order to carry out the actual cleaning operation, the motor (e.g. an electric motor) usually being implemented in the interior of the wiper system by means of a crank connected to a four-bar linkage. Furthermore, "wiper"/"wiper" is a general term in the art, and the meaning or application scope thereof should not be limited to only wiping/brushing off rain, water, but also be broadly construed to remove, e.g. scraping off, brushing off, wiping off water, moisture, condensation, snow, hail, dust, marks, etc., any dirt that may be attached to a surface to be cleaned, e.g. a vehicle windshield, e.g. for improving visibility for a driver, improving driving safety. The phrase "the second sub-motor bracket 32 is fitted to the motor housing 2 by the guide stopper 1 and is held fixed in position relative to the motor housing 2" not only means that the second sub-motor bracket 32 is held fixed in position relative to the motor housing 2 after the completion of the fixing, but also means that the second sub-motor bracket 32 does not change its position relative to the motor housing 2 due to the connection with the first sub-motor bracket 31 or with the motor housing 2, and particularly in the case where the second sub-motor bracket 32 is also mounted with the mounting pin 5 as shown in the drawing, the above-described positional change or displacement of the mounting pin 5 does not occur, thereby avoiding the problems mentioned in the background art, such as the out-of-tolerance (i.e., out-of-tolerance) problem. Furthermore, the connecting tube 4, for example a metal connecting tube, is usually assembled with the left and right axle seats of the wiper system (wherein the axle seats are connected with the swing arms of the wiper system, which are connected with the connecting rods of the wiper system, so that these parts form a four-bar linkage), so as to connect, fix and support the motor and the whole system together. As can also be seen from the above technical solution, the first sub-motor bracket 31 and the second sub-motor bracket 32 are connected to each other and fixed to the motor housing 2 (in the figure, the motor housing 2 is specifically a stator casing, for example), and the connection and the fixation are realized by a threaded connection.

As can be seen from the figure, the guide and limit device 1 includes a chute unit 11, and the second sub-motor bracket 32 is fitted to the motor housing 2 via the guide of the chute unit 11 and is held stationary with respect to the motor housing 2. The second sub-motor mount 32 can be mounted and dismounted by the slot unit 11 in such a way that it is plugged into the slot, so that the second sub-motor mount 32 is moved or mounted and dismounted in the direction of the slot, so that the possibility of displacement of the second sub-motor mount 32 in other directions, and therefore the mounting pin 5, is prevented during the mounting process and during the use after the mounting process of the second sub-motor mount is completed.

With regard to the guide and stop device 1, it is exemplary and shown that the guide and stop device 1, for example the runner unit 11, are arranged in pairs and opposite to each other, whereby the second sub-motor bracket 32 is mounted and fixed between the guide and stop device 1, for example the runner unit 11, which are paired with each other, for example, fitted to the motor housing 2 via the guide and stop device 1, so that the force applied to the second sub-motor bracket 32 is more uniform, and the second sub-motor bracket 32 is also facilitated to be stopped in all directions. The chute unit 11 can also be arranged symmetrically with respect to the longitudinal direction of the second sub-motor bracket 32, which can help to improve the above-mentioned technical effects. Furthermore, the chute unit 11 is also hollow, i.e., a through hole is opened in the chute unit 11, thereby achieving light weight. It should be understood that the embodiment of the chute unit 11 (or other components) can be modified depending on the actual application, including the number, arrangement position, shape, etc. thereof.

As already mentioned in part, the split motor mount 3 comprises a first sub-motor mount 31 and a second sub-motor mount 32 connected to each other, wherein the first sub-motor mount 31 is fixed to the motor housing 2 and is configured for the position limitation of the connecting tube 4 of the motor, so that the relative position of the connecting tube 4 can be ensured, and the second sub-motor mount 32 is for connection to the vehicle body, is fixed to the motor housing 2 by the guide position limitation device 1, and remains fixed in position relative to the motor housing 2. The first sub-motor holder 31 and the second sub-motor holder 32 can be connected to each other, for example, by a screw connection, but may of course be connected to each other by other means, for example, a snap connection, an adhesive connection, etc. On the one hand, the various split motor supports do not deform when the screws are tightened, because the two sliding grooves or the guide and limit means 1 can hold the position of the split motor support and limit the degrees of freedom, for example, in the up-down and front-back directions. On the other hand, the matching of various vehicle bodies can be completed only by replacing the second sub-motor support 32, and all the split-type motor supports 3 do not need to be replaced, so that the cost of tools and split-type motor support parts can be saved.

In particular and by way of example, during operation of the wiper system, vibrations in the motor region can arise as a result of vibrations of its wiper arm, with the result that after a long service life, stress is easily concentrated and thus damage is likely to occur. This multi-piece motor mount thus allows only the part of the split motor mount that is connected to the vehicle body (i.e., the second sub-motor mount 32) to be replaced when the above-described situation occurs, thereby saving replacement costs, and also is easier to replace, because it is only necessary to remove the second sub-motor mount 32 via the guide stopper 1 after disconnecting the second sub-motor mount 32 from the first sub-motor mount 31, and then install a new second sub-motor mount with the original fixing member (e.g., screw), thereby saving the number of parts to be replaced and costs. At the same time, this embodiment enables a quick adaptation to different types of vehicle bodies due to the possibility of a quick change of the second sub-motor mount 32, so that the entire motor or wiper system can be compatible with different types of vehicles.

A positioning pin 6 can also be formed on the motor housing 2, and correspondingly, the second sub-motor mount 32 is formed with a groove, in order to complete the positioning of the second sub-motor mount 32 when mounted, for example, with its top in contact with the positioning pin 6. In addition, the connection point of the split motor mount 3 or the second sub-motor mount 32 to the vehicle body is configured as a bent portion, for example, an upward bent portion, and the mounting pin 5 is configured at the bent portion so as to be able to be connected to the vehicle body well.

Optionally, the gate unit 11 is arranged on the motor housing 2 and/or is L-shaped. In particular, the vertical part of the L-shape is arranged vertically on the motor housing 2 and its horizontal part has or is configured as the sliding groove. The L-shaped form does not take up too much space and, since only the horizontal part acts as a slide, the function of the slide unit 11 or the guide and stop device 1 can be realized at a relatively high cost and is easy to manufacture and maintain.

Referring to fig. 5, there is shown a schematic view of another embodiment of a split motor mount 3 and guide and stop device 1 according to the present invention. For the parts of this embodiment that are the same as the previous embodiments, please refer to the previous description, and detailed description thereof is omitted.

As can be seen from this fig. 5, the guide and position limiting device 1 comprises a vertical column 12, the vertical column 12 is arranged on the motor housing 2, and the chute unit 11 is detachably fitted to the vertical column 12 and thereby performs the functions as described above. The gate unit 11 can of course also be of L-shaped design. This embodiment has the advantage that in the event of damage to the guide and stop device 1 due to time (for example the aforementioned stress concentration problem), the column 12 does not need to be replaced, but only the gate unit 11 needs to be replaced to enable the replacement. Since the new chute unit 11 can be installed with the original fixing members (e.g., screws), the number of parts to be replaced and the cost are saved. Due to the presence of the upright 12, the gate unit 11 can be constructed smaller or lower, which also contributes to a cost reduction when replacing the gate unit 11.

The chute unit 11 and the column 12 may be connected by a screw, an adhesive, a snap, or the like, as in the case of the second sub-motor bracket 32 and the first sub-motor bracket 31. For example, the uprights 12 are spaced apart from one another and are configured in pairs and facing one another, while the runner units 11, which are likewise in pairs, are seated on the two uprights 12, respectively. For this purpose, the slot unit 11 can be formed in a T-shape, the two corners of the T being connected to the two uprights 12, respectively, and the head of the T having the slot. The distributed arrangement design of the upright posts 12 can also save the whole manufacturing material and realize light weight.

As to the manner of manufacturing the guide limit device 1, the guide limit device 1 is, for example, die-cast on the motor housing 2, or the guide limit device 1 and the motor housing 2 are configured as one piece. The die casting manufacturing mode can realize the mass production of high-precision castings with excellent casting surfaces, and enables the castings to have high tensile strength and impact resistance. The integrated design has better safety, stability and strength and good impact resistance due to the fact that a connecting means (namely no seam) of all components of the integrated design is omitted, and the integrated design has the advantages of being easy to assemble and the like. The guide and stop device 1 can also be connected to the motor housing 2 by means of threaded fasteners. The threaded fastening connection is a detachable fixed connection which is widely used and has the advantages of simple structure, reliable connection, convenient assembly and disassembly and the like. Including but not limited to bolted connections, screwed connections, fastener-pack connections (e.g., externally threaded fasteners and washers); meanwhile, the specific form of the thread can be a triangular thread (common or imperial), a cylindrical pipe thread, a rectangular thread, and the like. Of course, the connection method can also adopt bonding, buckling and the like.

The present invention also relates to a motor for a wiper system of a vehicle, wherein the motor has any one of the above-mentioned guiding and limiting devices 1; and a wiper system for a vehicle, wherein the wiper system has the above-mentioned motor and the above-mentioned split motor bracket 3. With regard to the embodiments of the motor and of the wiper system, reference is made to the above description of the guide and stop device 1 and the split motor mount 3. Furthermore, it should be understood that the wiper system of the present invention may be installed on a variety of vehicles, including gasoline vehicles, diesel vehicles, cars, trucks, buses, hybrid vehicles, electric vehicles, and the like. Accordingly, the subject matter of the present invention is also directed to protecting various vehicles equipped with the wiper system of the present invention.

In summary, according to the technical scheme of the utility model, the motor bracket can be kept not to deform particularly in the installation process, so that the distance tolerance of the installation pin does not need to be adjusted in the production line; the requirement of replacing the vehicle body can be met.

It should be understood that all of the above preferred embodiments are exemplary and not restrictive, and that various modifications and changes in the specific embodiments described above, which may occur to those skilled in the art upon reading the teachings of the present invention, are intended to be within the scope of the appended claims.
