Description

Technical Field

[0001] The utility model relates to a protective cover, in particular to a motor protective cover. Background Art

[0002] The electronic starter is what people usually refer to as a motor, also known as a starter. It drives the starter rotor to rotate by rotating the energized coil in the magnetic field. The small gear on the rotor drives the engine flywheel to rotate, thereby driving the crankshaft to rotate and start the car. In order to protect the running motor, a protective cover is often installed on the outside of the motor to prevent the running motor from being affected by external falling objects.

[0003] Existing motor protection covers are all welded by welding various sheet metal parts to form a metal cover that conforms to the shape of the motor to cover the motor. The bottom of the cover is locked to the mounting surface. Although its strength can be guaranteed, the large-volume protection cover is inconvenient to install, disassemble and maintain. Workers need to constantly find various angles for installation and disassembly during installation, which is time-consuming and laborious.

[0004] Therefore, this case aims to provide a motor protection cover, which can not only ensure sufficient strength to protect the motor, but also realize split installation setting, so that workers can install it step by step, which is more convenient. Utility Model Content

[0005] The utility model provides a motor protection cover, which can effectively solve the above problems.

[0006] The utility model is achieved in this way:

[0007] A motor protection cover, comprising:

[0008] The bottom mounting structure comprises two vertical mounting rods perpendicular to the mounting surface and two oblique mounting rods inclined to the mounting surface, wherein the tops of the vertical mounting rods and the oblique mounting rods are both provided with stud heads;

[0009] A transverse support connection structure, comprising a support connection frame arranged above the vertical mounting rod and the oblique mounting rod, the support connection frame is provided with holes corresponding to the stud heads, nuts connected to the stud heads are locked in the holes, and a plurality of shafts are arranged at the bottom of the support connection frame;

[0010] The sleeve-type protection structure includes a protection seat covered on the outside of the motor, an axial hole is provided at the bottom of the protection seat at a position matching with the shaft rod, and when the protection seat is installed to the supporting connection frame, the shaft rod is inserted into the axial hole.

[0011] As a further improvement, the tops of the vertical mounting rod and the oblique mounting rod are both arc-shaped surfaces, the arc-shaped surfaces are clamped under the supporting connection frame, and the stud heads are fixedly connected at the axial center positions of the vertical mounting rod and the oblique mounting rod.

[0012] As a further improvement, the vertical mounting rod includes a round shaft portion connected to the arc surface, the lower end of the round shaft portion is connected to a flat portion, the lower end of the flat portion is connected to a locking portion, and the locking portion is locked on the motor or the mounting surface.

[0013] As a further improvement, the support connection frame is recessed downward on a side facing the motor output shaft.

[0014] As a further improvement, the protective seat includes two L-shaped connecting rods inserted into the supporting connecting frame, and two folding rods connected to the supporting connecting frame are welded to the outer side of the L-shaped connecting rod. The two folding rods are connected by a series rod, one end of the series rod is welded to the two L-shaped connecting rods, and the end of the series rod away from the L-shaped connecting rod is welded with a curved rod extending to the supporting connecting frame.

[0015] As a further improvement, a side of the series connecting rod away from the recess of the supporting connection frame is connected to an oblique support to the folding rod.

[0016] As a further improvement, a hanging ring is welded at the middle position of the series connecting rod.

[0017] The beneficial effects of the utility model are:

[0018] Compared with the existing integrated frame, the utility model divides the entire motor protection cover into three parts, namely, a bottom mounting structure, a lateral support connection structure and a sleeve-type protection structure. Therefore, during the installation stage, workers can first install the bottom mounting structure. Since the bottom mounting structure is relatively small in size, workers have a relatively free installation position for installation. After locking the bottom mounting structure, the lateral support connection structure and the bottom mounting structure are connected through the stud heads and holes to form a stable chassis frame. Finally, the sleeve-type protection structure is sleeved on the lateral support connection structure. Since the sleeve-type protection structure is a solid metal structure, it is very heavy. Therefore, although it adopts a sleeve-type method, it is difficult to be shaken. It can form a stable protective surface on the outside of the motor to prevent the motor from being damaged by heavy objects or large-area objects, thereby making it more convenient for workers to install, disassemble and repair without reducing protective measures.

[0024] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments.

[0025] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0026] Reference Figure 1 to Figure 4As shown, a motor protection cover comprises: a bottom mounting structure 10, comprising two vertical mounting rods 11 perpendicular to a mounting surface, and two oblique mounting rods 12 obliquely arranged with respect to the mounting surface, wherein the tops of the vertical mounting rods 11 and the oblique mounting rods 12 are both provided with stud heads 13; a lateral supporting and connecting structure 20, comprising a supporting and connecting frame 21 arranged above the vertical mounting rods 11 and the oblique mounting rods 12, wherein the supporting and connecting frame 21 is provided with holes corresponding to the stud heads 13, wherein nuts connected with the stud heads 13 are locked in the holes, and a plurality of shaft rods 22 are arranged at the bottom of the supporting and connecting frame 21; a sleeve-type protection structure, comprising a protection seat 31 which is arranged on the outside of the motor, wherein an axial hole is arranged at the bottom of the protection seat 31 which cooperates with the shaft rod 22, and when the protection seat 31 is installed to the supporting and connecting frame 21, the shaft rod 22 is inserted into the axial hole.

[0027] The motor protection cover is actually a cover installed on the outside of the motor to wrap the entire motor. However, since the temperature of the motor is very high when working, a fully enclosed protection cover cannot be used. In this embodiment, a truss-type protection cover is used to protect the motor without affecting its heat dissipation effect.

[0028] Compared with the existing integrated frame, the utility model divides the entire motor protection cover into three parts, namely, the bottom mounting structure 10, the lateral support connection structure 20 and the sleeve-type protection structure, so that during the installation stage, workers can first install the bottom mounting structure 10. Since the volume of the bottom mounting structure 10 is relatively small, workers have a relatively free installation position for installation. After locking the bottom mounting structure 10, the lateral support connection structure 20 and the bottom mounting structure 10 are connected to the hole through the stud head 13 to form a stable chassis frame. Finally, the sleeve-type protection structure is sleeved on the lateral support connection structure 20. Since the sleeve-type protection structure is a solid metal structure, it is very heavy. Therefore, although it adopts a sleeve-type method, it is difficult to be shaken. It can form a stable protective surface on the outside of the motor to prevent the motor from being damaged by heavy objects or large-area objects, thereby making it more convenient for workers to install, disassemble and repair without reducing protective measures.

[0029] When the vertical mounting rod 11 and the oblique mounting rod 12 cooperate, the tops of the vertical mounting rod 11 and the oblique mounting rod 12 are both arc-shaped surfaces, and the arc-shaped surfaces are clamped under the supporting connection frame 21. The stud head 13 is fixedly connected to the axial center position of the vertical mounting rod 11 and the oblique mounting rod 12. In order to avoid the protruding stud head 13 blocking the installation space of the motor, the stud head 13 does not penetrate the supporting connection frame 21, and the connection between the nut and the stud head 13 also adopts a countersunk hole connection method to avoid the protruding connection structure compressing the normal installation space of the motor.

[0030] During the installation of the motor protection cover, in order to make it detachable, a locking and fixing method is basically adopted, and since the installation position is not fixed, it is basically inserted into any gap. Therefore, the vertical mounting rod 11 in this embodiment includes a round shaft portion 111 connected to the arc surface, and the lower end of the round shaft portion 111 is connected to a flat portion 112, and the lower end of the flat portion 112 is connected to a locking portion 113, and the locking portion 113 is locked on the motor or the mounting surface. In fact, except for the different installation angles, the rest of the structures of the vertical mounting rod 11 and the oblique mounting rod 12 are the same.

[0031] In order to make room for the motor, the support connection frame 21 is recessed downward toward the side where the motor output shaft is installed, thereby facilitating the coordination of the motor with other power actuators.

[0032] The entire protection seat 31 is also separately provided after considering the shape of the motor. Specifically, the protection seat 31 includes two L-shaped connecting rods 311 inserted into the support connection frame 21, and two folding rods 312 connected to the support connection frame 21 are welded to the outer side of the L-shaped connecting rod 311. The two folding rods 312 are connected by a series rod 313, and one end of the series rod 313 is welded to the two L-shaped connecting rods 311, and the end of the series rod 313 away from the L-shaped connecting rod 311 is welded with a curved rod 314 extending to the support connection frame 21. On the basis of making way for other power actuators, vertical support structures are made in other directions as much as possible, such as the L-shaped connecting rod 311, the series rod 313 and the curved rod 314.

[0033] In order to improve the top supporting capacity of the entire protective cover, a diagonal brace 315 is connected to the folding rod 312 on the side of the serial rod 313 away from the recess of the supporting connection frame 21. In this embodiment, only one diagonal brace 315 is set, and multiple ones can also be set in the actual application stage.

[0034] Since the entire protective cover is made entirely of alloy, it is very heavy, especially the sleeve-type protective structure. Therefore, in order to facilitate the installation of the entire protective cover, a hanging ring 316 is welded to the middle position of the series rod 313. The entire cover body can be adjusted to a specified position through the hanging ring 316, and then the position can be manually corrected for installation.

[0035] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
