Description

Technical Field

[0001] This utility model relates to the field of hay combing machine technology, and in particular to a general-purpose machine housing structure and hay combing machine. Background Technology

[0002] As a commonly used garden power tool, the core power component of a lawn comb is usually provided by an electric motor. Depending on the application scenario and power requirements, a lawn comb may use a DC motor or an AC motor as the drive source. These two types of motors have significant differences in structural design. DC motors are usually longer in axial length, while AC motors are usually more compact. The ventilation positions of the lawn comb housing must strictly correspond to the position of the selected motor fan to ensure that the cooling airflow can effectively flow through the motor for heat dissipation. Currently, due to the fundamental difference in the position of the motor fan, the housing structure designed for one type of motor (such as DC) cannot be directly compatible with another type of motor (such as AC). Different housing structures need to be developed and produced separately for DC motors and AC motors, which leads to a significant increase in mold costs and limits the versatility of the product. Utility Model Content

[0003] In view of the shortcomings of the existing technology, this utility model provides a universal housing structure and a hay comber, which solves the problem of low universality of the housing structure of the hay comber in the existing technology.

[0006] Compared with the prior art, the present invention has the following beneficial effects:

[0007] By setting a mounting frame with mounting positions on the base and opening two spaced ventilation openings on the base, the same base can be used to install both DC motors and AC motors. The two ventilation openings correspond to DC motors with longer axial lengths and AC motors with more compact structures, respectively. There is no need to design and manufacture separate bases for DC motors and AC motors. One mold can cover the two mainstream motor types, which greatly reduces the mold development and production costs.

[0024] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0025] This utility model embodiment proposes a universal housing structure for mounting a motor 2, including a base 1 and a cover plate 5 connected to the base 1. The motor 2 is mounted on the base 1. The housing structure also includes a mounting frame 4, which is disposed on the base 1 to form a mounting position 401 for accommodating the fan of the motor 2. The base 1 has two ventilation openings 101, which are spaced apart at the mounting position 401, and one of the ventilation openings 101 corresponds to the fan of the motor 2.

[0026] In the embodiments of this utility model, such as Figure 2 As shown, the drive end of motor 2 is located at the end of base 1 and is used to connect to the drive wheel of the comber, so that the drive wheel rotates to drive the comber to move. The heat dissipation end of motor 2 is located in the middle of base 1. When installing motor 2, it is directly installed on base 1. The installation method can be direct bolt fixing or clamp installation. After installation, under the action of two ventilation ports 101, the same base 1 can simultaneously accommodate DC motors and AC motors. The two ventilation ports 101 correspond to DC motors with longer axial lengths and AC motors with more compact structures, respectively. There is no need to design and manufacture special bases 1 for DC motors and AC motors separately. One mold can cover the two mainstream motor types 2, which greatly reduces the mold development and production costs. Moreover, when dealing with DC motors or AC motors of different lengths, the appropriate DC motor or AC motor can be installed according to the length of the motor.

[0027] Based on the above solutions, such as Figure 3 As shown, the housing structure also includes a sealing plate 3, which is fastened to one of the ventilation openings 101. By detachably fastening the sealing plate 3 to one of the ventilation openings 101, the cooling airflow is actively guided. By fastening the sealing plate 3 to the ventilation opening 101 that does not correspond to the current position of the motor 2 fan, the cooling airflow is always aligned with the current position of the motor 2 fan.

[0028] When installing the sealing plate 3, it can be installed on the corresponding vent 101 by direct snap-fit. However, to further ensure the installation stability of the sealing plate 3, such as... Figure 5 As shown, mounting holes 302 are provided at both ends of the sealing plate 3. The mounting holes 302 are bolted to the base 1. The bolt connection provides a firm mechanical locking force, ensuring that the sealing plate 3 fits tightly against the edge of the ventilation opening 101 under high-speed operation or vibration conditions of the equipment, effectively preventing loosening or displacement.

[0029] Moreover, the side of the sealing plate 3 extends along its thickness direction to form a protrusion 301. The protrusion 301 is engaged with the vent 101. The protrusion 301 forms a guide structure, which enables the sealing plate 3 and the vent 101 to be quickly pre-aligned and temporarily fixed before the bolts are tightened. The position of the sealing plate 3 can be automatically corrected simply by embedding the protrusion 301 into the edge of the vent 101, which simplifies the assembly process.

[0030] Specifically, such as Figure 3 As shown, the base 1 is provided with a support plate 402. The support plate 402 is located at the mounting position 401 and between the two ventilation openings 101. When a motor 2 with a longer axial distance is used, the support plate 402 directly supports the fan mounting area at the bottom of the motor 2, forming a local reinforcement structure, which significantly improves the load-bearing capacity of the base 1 on the weight of the motor 2 and provides a flat and stable mounting base for the fan.

[0031] Specifically, such as Figure 4 As shown, the mounting frame 4 is provided with several mounting posts 403 along its circumference, which can adapt to the mounting points of different motors 2 and improve the adaptability to the fixed installation of various motors 2.

[0032] Specifically, with the cover plate 5 installed, it can be fixedly connected to the base 1 by means of a snap-fit ​​mechanism. To further ensure the stability of the connection between the cover plate 5 and the base 1, such as... Figure 2 As shown, the base 1 is provided with several connecting posts 103, which are connected to the cover plate 5 by bolts. The connecting posts 103 are provided with threaded holes, which correspond to the holes on the cover plate 5. The connection strength is ensured by passing the bolts through the holes on the cover plate 5 and installing them into the threaded holes of the connecting posts 103.

[0033] At the same time, such as Figure 2 As shown, the base 1 has a positioning edge 102 on its edge, and the cover plate 5 is snapped onto the positioning edge 102. The inner diameter of the ring structure formed by the positioning edge 102 is smaller than the outer edge of the base 1, so that the outer edge of the base 1 and the positioning edge 102 form a stepped structure. The stepped structure can guide the cover plate 5 to be installed quickly and also realizes a certain limiting function, which facilitates the subsequent fixed installation of the cover plate 5.

[0034] Moreover, such as Figure 1 As shown, the cover plate 5 is provided with a handle 501. With the help of the handle 501, when disassembling the cover plate 5, it is convenient to lift the cover plate 5 and disassemble it. Furthermore, when storing the entire grass comb, the handle 501 also facilitates the lifting and transportation of the grass comb.

[0035] like Figure 1As shown, this utility model embodiment also proposes a grass comber, including the above-mentioned general-purpose housing structure. The specific structure of the housing structure is as described in the above embodiment. Since this grass comber adopts all the technical solutions of the above embodiment, it has at least all the beneficial effects brought about by the technical solutions of the above embodiment, which will not be described in detail here.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
