[0002] An electric tricycle is a three-wheeled transport vehicle that uses an electric motor to drive a battery for power output. The motor is usually installed at the bottom of the vehicle's cargo box, and a corresponding enclosure structure is set up outside the motor to protect the internal battery cells.

[0003] The patent specification with announcement number CN108631499A discloses a differential motor housing connection device for an electric tricycle, including a housing connecting plate body and a washer. The washer is set in the input wheel hole. An upper mounting ear plate is provided at the rear of the upper connecting cavity. An upper mounting hole is provided on the upper mounting ear plate. An upper ear plate is provided at the middle of the upper end of the upper connecting cavity, an ear plate I is provided at the upper edge, a middle ear plate is provided at the middle edge, an ear plate II is provided at the lower edge, and a lower ear plate is provided at the lower end edge. An upper fixing hole is provided on the upper ear plate, a fixing hole I is provided on ear plate I, a middle fixing hole is provided on the middle ear plate, a fixing hole II is provided on ear plate II, and a lower fixing hole I is provided on the lower ear plate.

[0004] This type of motor housing connection device integrates existing three-hole, four-hole, and five-hole differential motor housing structures into one unit to achieve the function of adapting to a variety of different motors; however, the shortcomings of this technical solution are that, in order to adapt to different motors, a large number of redundant ear plate structures are added, resulting in a large overall mass as a motor housing connection component, thereby increasing the load pressure when the electric tricycle motor is traction.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0006] The purpose of this utility model is to provide a tricycle motor housing, and the technical problem to be solved is as follows: the existing tricycle motor housing connection device has a large self-weight when in use, which reduces the effective power of the motor during operation.

[0007] The objective of this utility model can be achieved through the following technical solutions:

[0008] A tricycle motor housing includes a main shaft disc with a main shaft hole in the center. A flange is fixedly connected to one end of the main shaft disc, and a main gear shaft seat is fixedly connected to one side of the top of the flange. A main gear shaft hole is provided through the top of the main gear shaft seat. Multiple through lugs are evenly provided along the circumferential side of the top of the main gear shaft seat. Lugs are provided on both sides of the main gear shaft seat near the flange. Multiple reinforcing ribs are provided on both the main shaft disc and the main gear shaft seat. A weight-reducing groove is provided on one side of the main shaft disc, and an inner cavity is provided on the inner side of the main gear shaft seat.

[0009] As a further embodiment of this utility model: two weight-reducing grooves are symmetrically arranged on the inner side of the spindle disk near the flange, the inner cavity near the flange is thin plate-shaped, and the inner cavity away from the flange is fitted with an inner seat to the main gear shaft hole.

[0010] As a further embodiment of this utility model: a sealing groove 1 is provided at the bottom of the inner side of the spindle hole, a sealing groove 2 is provided at the bottom of the inner connector, and a bearing groove is provided at the top of both the sealing groove 1 and the sealing groove 2.

[0011] As a further embodiment of this utility model: a positioning groove is provided on the outer side of the main gear shaft hole, and three external connecting holes are provided in the middle of the main gear shaft seat along the circumferential direction.

[0012] As a further embodiment of this utility model: the through lug passes through the main gear shaft seat, and the side of the lug closest to the main gear shaft hole is closed.

[0013] As a further embodiment of this utility model: the reinforcing ribs include three reinforcing ribs one fixedly connected between the inner cavity and the outer hole, three reinforcing ribs two fixedly connected between the inner seat and the flange, and four reinforcing ribs three evenly arranged between the two sides and the top of the spindle disk and the flange.

[0014] The beneficial effects of this utility model are:

[0015] By incorporating multiple through lugs, connecting lugs, and external holes, the connector can be stably connected to the motor housing, improving connection stability. Furthermore, by setting weight-reducing grooves on the inner side of the spindle disc and an internal cavity on the inner side of the main bearing seat, the overall mass of the connector is reduced. Simultaneously, multiple reinforcing ribs are placed on the outer side of the spindle disc and the inner side of the main gear seat, maintaining the overall structural strength of the connector while reducing mass. This combination of improved connection stability, reduced body mass, and enhanced overall structural strength allows the connector to maximize protection of the motor housing, minimize impact on motor load, and improve motor operating efficiency.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0021] like Figures 1 to 2 As shown, a tricycle motor housing includes a main shaft disk 1, a main shaft hole 2 in the middle of the main shaft disk 1, a flange 3 fixedly connected to one end of the main shaft disk 1, a main gear shaft seat 4 fixedly connected to one side of the top of the flange 3, a main gear shaft hole 5 penetrating through the top of the main gear shaft seat 4, five through-shaft lugs 6 evenly arranged along the circumferential side of the top of the main gear shaft seat 4, lugs 7 on both sides of the main gear shaft seat 4 near the flange 3, multiple reinforcing ribs 8 on both the main shaft disk 1 and the main gear shaft seat 4, a weight reduction groove 9 on one side of the main shaft disk 1, and an inner cavity 10 on the inner side of the main gear shaft seat 4. The weight reduction groove 9 and the inner cavity 10 are used to reduce the weight of the housing connecting parts.

[0022] It should be noted that the connector is used to connect the inner core of the motor to the main gear of the motor housing. The outer surfaces of the main shaft disk 1 and the main gear shaft seat 4 are evenly coated with black anti-corrosion paint to improve the service life of the connector. The flange 3 has a semi-circular structure and four connecting holes are evenly arranged along its circumference for connecting the connector to the motor. The main shaft hole 2 is used to install the motor output shaft, and the main gear shaft seat 4 is used to install the main gear of the motor drive.

[0023] Two weight-reducing grooves 9 are symmetrically arranged on the inner side of the spindle disk 1 near the flange 3. The inner cavity 10 is thin plate-shaped on the side near the flange 3. The inner cavity 10 is fitted with an inner seat 11 on the side away from the flange 3 to fit the main gear shaft hole 5. That is, by setting weight-reducing grooves 9 and inner cavities 10 on the inner side of the spindle disk 1 and the main gear shaft seat 4, the weight of the connecting parts is reduced, thereby reducing their overall mass and improving the effective power of the motor during operation.

[0024] A sealing groove 12 is provided at the bottom of the inner side of the spindle hole 2, and a sealing groove 13 is provided at the bottom of the inner connector 11. A bearing groove 14 is provided at the top of both the sealing groove 12 and the sealing groove 13. That is, by providing the sealing groove 12 and the sealing groove 13 on the inner side of the spindle disk 1 and the main gear shaft seat 4, the sealing performance of the connection between the main gear and the motor output shaft is improved, thereby extending its service life. In addition, the bearing groove 14 is used to install the bearing for auxiliary rotation.

[0025] A positioning groove 15 is provided on the outer side of the main gear shaft hole 5, and three external connecting holes 16 are provided in the middle of the main gear shaft seat 4 along the circumferential direction; each through-shaft lug 6 passes through the main gear shaft seat 4, and the side of the connecting lug 7 near the main gear shaft hole 5 is closed; that is, after the main gear is installed in the main gear shaft hole 5, it needs to be fixed by an external protective plate (not shown) on the outside of the main gear shaft seat 4. The external protective plate is initially positioned by inserting it into the positioning groove 15, and is locked to the connecting parts by bolts installed in the three external connecting holes 16. The connecting parts also need to be fixed to the motor housing. At this time, it is necessary to connect the external protective plate to the motor housing by installing bolts through each through-shaft lug 6. At the same time, the motor housing is also locked to the two connecting lugs 7 by bolts for locking and reinforcement, thereby realizing the connection between the connecting parts and the housing, and realizing the protection function of the internal battery cell mechanism of the motor.

[0026] The reinforcing ribs 8 include three reinforcing ribs 81 fixedly connected between the inner cavity 10 and the outer hole 16, three reinforcing ribs 82 fixedly connected between the inner seat 11 and the flange 3, and four reinforcing ribs 83 evenly fixedly connected between the two sides and the top of the spindle disk 1 and the flange 3. That is, the stability of the connection is ensured by the through lugs 6, lugs 7 and the outer hole 16. On this basis, the overall mass of the connector is reduced by setting the weight reduction groove 9 and the inner cavity 10, and the structural strength of the reduced mass connector is improved by setting multiple reinforcing ribs 8. This allows the connector to maintain connection stability and structural support strength while reducing the impact of its own weight on the motor load and improving the effective power of the motor during operation.

[0027] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
