Description

Technical Field

[0001] This utility model relates to the field of motor housing technology, and in particular to a drive motor housing. Background Technology

[0002] Patent CN213043504U discloses a motor housing, including a housing with an annular fixing bracket on its lower side wall. The fixing bracket has a base plate protruding radially from its lower end, and the fixing bracket and the base plate form an L-shape in cross-section. The base plate has annularly arranged bolt holes. A heat dissipation plate is evenly distributed along the axial direction of the outer periphery of the housing, and the housing also includes transverse reinforcing ribs disposed on the outer periphery of the housing and penetrating the heat dissipation plate. This utility model has a simple and ingenious structure, high mechanical strength, firm connection, easy installation and maintenance, long service life, and is safe and reliable.

[0003] The existing technical solutions mentioned above have the following drawbacks: Although the structural strength of the motor housing can be improved, the installation of the drive motor housing still relies on traditional bolt fastening. This requires first aligning the through holes on the drive motor housing with the threaded holes on the fixed base, and then sequentially passing the bolts through the motor housing and threading them onto the fixed base for installation. This operation is relatively complicated and makes it inconvenient to quickly and stably align the motor housing and the fixed base, thus affecting the actual installation efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a drive motor housing to solve the defect of existing drive motor housings that make it inconvenient and difficult to quickly and stably connect the motor housing and the fixed base.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a drive motor housing, comprising a motor housing;

[0006] A positioning bracket is fixedly connected to the bottom of the motor housing, and a snap-fit ​​mechanism is installed at the bottom of the positioning bracket.

[0007] The locking mechanism includes a docking block fixedly installed at the bottom of the positioning bracket. The docking block has a movable groove inside. A guide sleeve is fixedly connected inside the docking block. A guide groove is opened inside the guide sleeve. A locking rod is movably connected inside the guide sleeve. A guide plate is fixedly connected to the outer wall of the locking rod. A return spring is fixedly connected to one end of the locking rod.

[0008] Preferably, a positioning base is installed at the bottom of the positioning bracket, and a docking groove is provided inside the positioning base, and a slot is provided on the inner side wall of the docking groove.

[0009] Preferably, the docking block forms a sliding structure with the locking rod through the movable groove, and the guide plate forms a sliding structure with the guide sleeve through the guide groove, so that the locking rod can slide along the movable groove and be retracted into the docking block.

[0010] Preferably, the guide plate is symmetrically arranged about the central axis of the lever, and the other end of the lever is hemispherical, which allows the lever to slide stably along the guide sleeve.

[0011] Preferably, the docking block is engaged with the positioning base via a docking groove, and the locking rod is engaged with the positioning base via a locking groove, allowing the docking block to be inserted into the docking groove for docking.

[0012] Preferably, the positioning base has a threaded hole inside, the positioning bracket has a bolt installed inside, and the outer wall of the bolt has a washer installed.

[0013] Preferably, the bolt is threadedly connected to the positioning base through a threaded hole, and the positioning bracket has an open hole design, which facilitates the positioning bracket and the positioning base to be limited.

[0014] The advantages of the drive motor housing provided by this utility model are as follows:

[0015] By using the motor housing, positioning bracket, positioning base, docking groove, and locking slot, the motor housing is moved so that the docking block is inserted into the docking groove. This causes the locking rod to be squeezed and slide along the movable groove into the docking block, allowing the docking block to dock with the docking groove. This facilitates quick docking of the positioning bracket and positioning base, improving the efficiency of motor housing installation.

[0016] Furthermore, the cooperation between the guide plate and the guide groove can improve the stability of the sliding of the clamp rod and further enhance the stability of the docking installation.

[0017] Furthermore, under the action of the return spring, the locking rod can be reset and inserted into the slot for limiting, further improving the stability of the docking between the positioning bracket and the positioning base;

[0018] The motor housing, positioning bracket, positioning base, threaded hole, bolt, and washer are designed so that the bolt can be inserted into the threaded hole for limiting by rotating the bolt, which facilitates the stable connection between the positioning bracket and the positioning base and allows for quick installation of the motor housing.

[0019] Furthermore, the shims can increase the contact area between the bolts and the positioning bracket, thereby further improving the stability of the positioning bracket's positioning. Attached Figure Description
