Description
Technical Field
[0001] This utility model relates to the field of motor assembly technology, and in particular to a motor mounting structure. Background Technology
[0002] In devices such as air conditioning equipment that require stepper motors, the installation structure of the stepper motor directly affects the assembly efficiency, maintenance convenience, and operational stability of the equipment. Currently, the installation of stepper motors in air conditioning equipment mostly relies on traditional connection methods, such as bolt fastening or multi-component splicing snap-fit connections. These methods have significant limitations in practical applications.
[0003] When using bolts for fastening, specialized tools such as screwdrivers and wrenches are required to tighten or loosen each bolt individually. Because the internal space of air conditioning equipment is typically quite confined, this makes tool operation difficult, leading not only to longer motor installation times and extended overall equipment assembly cycles, but also to the risk of bolt stripping or loss during disassembly due to limited space, increasing maintenance costs and complexity. Furthermore, repeated bolt loosening and tightening operations can damage the motor or equipment housing, affecting component lifespan.
[0004] While existing multi-component interlocking snap-fit connection structures do not require tools, the snap-fit connection relies heavily on direct insertion and removal or multi-directional splicing between components. This design makes precise control of the snap-fit gap difficult. Excessive gap can cause vibration and displacement during motor operation, affecting transmission stability; excessive interference fit requires significant external force during installation and disassembly, easily causing snap-fit breakage or deformation, also hindering convenient assembly and disassembly. Furthermore, some snap-fit structures require multi-directional adjustment of the motor during installation, making quick positioning and fixation difficult, further reducing assembly efficiency. Utility Model Content
[0005] This utility model provides a motor mounting structure to solve the defects of low assembly efficiency, difficult maintenance and operation, easy damage to components and poor transmission stability when stepper motors in air conditioning equipment are fastened with bolts or connected by multi-part splicing buckles. It realizes the motor's rapid positioning and installation, no need for special tools for loading and unloading, reduces the risk of component damage and improves operational stability.
[0006] This utility model provides a motor mounting structure, including a mounting base and a mating part. The mounting base has a mounting cavity for accommodating the motor and also includes a snap-fit structure. The mating part is located on the outer wall of the motor, and its shape is adapted to the snap-fit structure on the mounting base. The motor can be rotatably placed within the mounting cavity of the mounting base. During assembly, by rotating the motor relative to the mounting base to a specific angle, the mating part and the snap-fit structure can form a snap-fit engagement. According to this embodiment, motor assembly and disassembly can be completed without special tools, improving assembly efficiency. Simultaneously, the rotating snap-fit engagement ensures the motor is securely fixed, avoiding the operational difficulties of traditional connection methods.
[0007] According to one embodiment of the present invention, the side wall of the mounting cavity is provided with a side notch to accommodate the irregularly shaped structure of the motor side; the mounting cavity has a top opening for the motor to enter and exit, and in the assembled state, the mating part is located above the top opening. According to this embodiment, it can avoid interference from the irregularly shaped motor structure, facilitate the placement and removal of the motor through the top opening, and the exposed mating part makes it easy to confirm the assembly status, thus improving operational convenience.
[0008] According to one embodiment of the present invention, the horizontal cross-sectional shape of the sidewall of the mounting cavity is C-shaped, and the opening angle of the side notch relative to the sidewall of the mounting cavity is greater than or equal to 90 degrees and less than 180 degrees. According to this embodiment, the C-shaped sidewall can form a wraparound restraint on the motor, and the 90°-180° opening angle balances the accommodating space for irregular structures with the radial stability of the motor.
[0009] According to one embodiment of this utility model, the mounting base has two snap-fit structures; the two mating parts are respectively disposed on the motor at positions corresponding to the snap-fit structures. According to this embodiment, the symmetrical double-snap layout provides balanced clamping force, prevents motor tilting or deviation, and forms double anti-disengagement protection, extending the service life of the structure.
[0010] According to one embodiment of this utility model, the snap-fit structure is provided with a slot opening for the mating part to enter and exit; the slot opening is oriented clockwise or counterclockwise. During assembly, after the motor is placed into the mounting cavity, the motor is rotated in the opposite direction to the slot opening, so that the mating part is embedded in the slot opening. According to this embodiment, the oriented slot opening and the counterclockwise rotation prevent the mating part from accidentally disengaging, while guiding the mating part to precise engagement, reducing the difficulty of operation.
[0011] According to one embodiment of the present invention, the snap-fit structure includes an elastic pressure plate disposed on the top of the mounting base. The elastic pressure plate is bent to clamp the mating part between the end of the elastic pressure plate and the top surface of the mounting base. According to this embodiment, the elastic clamping force of the elastic pressure plate can securely fix the mating part while avoiding compression damage to the components caused by rigid connections.
[0012] According to one embodiment of this utility model, the snap-fit interface further includes a positioning block disposed opposite to the elastic pressure plate, the positioning block having a wedge-shaped surface; during assembly, the mating part first passes over the positioning block along the wedge-shaped surface, then enters the space between the elastic pressure plate and the top surface of the mounting base, and is clamped by the elastic pressure plate. According to this embodiment, the wedge-shaped surface of the positioning block reduces the resistance of the mating part passing over, and simultaneously forms a dual fixation with the elastic pressure plate—both horizontally limiting and vertically clamping—improving the stability of the mating part and preventing horizontal displacement and retraction.
[0013] According to one embodiment of this utility model, the end of the elastic pressure plate facing the positioning block is provided with a raised edge extending obliquely away from the top surface of the mounting base. During assembly, after the mating part passes the positioning block, it lifts the raised edge to enter between the top surface of the elastic pressure plate and the mounting base. According to this embodiment, the raised edge forms a guide inlet, enlarges the clamping gap inlet, avoids impact and jamming of the mating part, reduces the alignment accuracy requirement, and further improves assembly smoothness.
[0014] According to one embodiment of this utility model, the mating part is a plate-shaped structure; wherein, the width of the mating part is adapted to the distance between the positioning block and the elastic pressure plate; the thickness of the mating part is less than the maximum distance between the raised edge and the top surface of the mounting base, and greater than the minimum distance between the raised edge and the top surface of the mounting base. According to this embodiment, the plate-shaped mating part is designed to fit the dimensions, ensuring that the mating part smoothly enters the clamping gap while also ensuring that the elastic pressure plate applies sufficient clamping force.
[0015] According to one embodiment of the present invention, a limiting hole is provided on the mating part; in the assembled state, at least a portion of the elastic pressure plate is inserted into the limiting hole to form a limiting fit. According to this embodiment, the fitting structure of the limiting hole and the elastic pressure plate can prevent the mating part from sliding out, while also indicating that the assembly is in place, thus taking into account both fixation stability and assembly accuracy.
[0016] The motor mounting structure provided by this utility model features a mounting base with a mounting cavity and a snap-fit structure, and a mating part on the outer wall of the motor that adapts to the snap-fit structure. Utilizing the design that allows the motor to rotatably rest within the mounting cavity, simply rotating the motor to a specific angle allows the mating part to securely engage with the snap-fit structure. According to this solution, on the one hand, it eliminates the need for specialized tools such as screwdrivers and wrenches, solving the problems of traditional bolt fastening methods, which are difficult to operate in confined spaces, time-consuming to assemble and disassemble, and prone to bolt stripping, loss, and damage to components. On the other hand, compared to multi-part splicing snap-fit structures that require insertion, removal, or multi-directional adjustment, the rotating snap-fit method eliminates the need for repeated adjustments to the motor position, achieving efficient motor assembly, convenient maintenance, and stable operation.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0025] The following is combined with Figures 1-4 This invention describes a specific implementation of the motor mounting structure.
[0026] like Figure 1 and Figure 2 As shown, this utility model provides a motor mounting structure, including a mounting base 10 and a mating part 20. The mounting base 10 has a mounting cavity 11 for accommodating the motor and a snap-fit structure. The mating part 20 is disposed on the outer wall of the motor, and its shape is adapted to the snap-fit structure on the mounting base 10. The motor can be rotatably placed in the mounting cavity 11 of the mounting base 10. During assembly, by rotating the motor relative to the mounting base 10 to a specific angle, the mating part 20 and the snap-fit structure can form a snap-fit engagement. Specifically, the inner diameter of the mounting cavity 11 matches the outer diameter of the motor, ensuring that the motor can stably fit against the cavity wall after placement while retaining rotational allowance and avoiding radial wobble. The fitting form of the snap-fit structure and the mating part 20 can be flexibly designed. For example, the snap-fit structure can be an arc-shaped block protruding from the inner wall of the mounting cavity 11, and the mating part 20 can be an arc-shaped groove opened on the outer wall of the motor; or the snap-fit structure can be an L-shaped groove opened on the inner wall of the mounting cavity 11, and the mating part 20 can be an L-shaped block protruding from the outer wall of the motor; or the snap-fit structure can be an elastic protrusion on the inner wall of the mounting cavity 11, and the mating part 20 can be a positioning recess on the outer wall of the motor, etc. When the motor is initially placed into the mounting cavity 11, the mating part 20 and the snap-fit structure are misaligned, and the motor is only limited by the mounting cavity 11; by rotating the motor around its own central axis by 30°-60° (the specific angle depends on the structural adaptability) to a specific angle, the two can be fitted and fixed, and can be disassembled by rotating in the opposite direction, without the need for additional tools.
[0027] Furthermore, the aforementioned motor mounting structure can be applied to the mounting structure of stepper motors in air conditioning systems. Specifically, stepper motors in air conditioning systems are often installed in confined spaces such as indoor unit fan drive modules and outdoor unit valve control components. Traditional installation methods are easily limited by space constraints, leading to inconvenient operation. When this structure is applied to this scenario, the mounting base 10 can be integrated into the inner wall of the air conditioning housing through one-piece injection molding or bolt pre-fixing. The opening of the mounting cavity 11 faces the inspection port side, facilitating hand operation. The outer wall of the stepper motor is machined with corresponding mating parts 20 according to the snap-fit structure of the mounting base 10—for example, one is a snap-fit block, and the other is a snap-fit groove. Because the stepper motor is lightweight, the operator can insert it into the mounting cavity 11 with one hand and rotate the snap-fit to fix it. During operation, the engagement of the snap-fit and the mating part 20, combined with the radial limiting effect of the mounting cavity 11, ensures stable torque transmission of the stepper motor, reducing abnormal noise and transmission errors. During maintenance, there is no need to disassemble other parts of the air conditioner; the motor can be removed by rotating it in reverse through the inspection port, significantly reducing maintenance difficulty and time consumption, and adapting to the compact space and efficient operation and maintenance requirements of air conditioning systems.
[0028] like Figure 1 and Figure 3 As shown, according to a motor mounting structure of this utility model, the side wall of the mounting cavity 11 is provided with a side notch 12 to accommodate irregularly shaped structures on the side of the motor; the mounting cavity 11 has a top opening for the motor to enter and exit, and in the assembled state, the mating part 20 is located above the top opening. Specifically, the irregularly shaped structures on the side of the motor usually include wiring terminals, heat dissipation fins, or positioning protrusions, etc. If these structures do not have suitable accommodating space, the motor may not be able to be smoothly placed into the mounting cavity 11 or may be misaligned after placement. The size and shape of the side notch 12 are designed according to the specifications of the irregularly shaped motor structure to avoid mutual squeezing damage between structures. The diameter of the top opening of the mounting cavity 11 is adapted to the outer diameter of the motor, facilitating the vertical placement of the motor from above. After assembly, the mating part 20 is located above the top opening, making it easy for operators to visually confirm the snap-fit engagement status. During disassembly, force can be applied directly to the top mating part 20 to rotate the motor, improving the ease of assembly and disassembly.
[0029] Furthermore, such as Figure 2 and Figure 4As shown, according to a motor mounting structure of this utility model, the horizontal cross-sectional shape of the sidewall of the mounting cavity 11 is C-shaped, and the opening angle of the side notch 12 relative to the sidewall of the mounting cavity 11 is greater than or equal to 90 degrees and less than 180 degrees. The C-shaped horizontal cross-section of the sidewall can form a wraparound restraint on the motor. Compared with a fully enclosed circular cross-section, it retains sufficient accommodation space and can avoid irregular side structures of the motor through the side notch 12. The opening angle of the side notch 12 is preferably set to ≥90° and <180°. If the opening angle is less than 90°, the space in the side notch 12 is too small to accommodate large irregular structures; if the opening angle is ≥180°, the encircling range of the C-shaped sidewall for the motor is too small to provide sufficient radial support, and the motor is prone to shifting or shaking in the mounting cavity 11; while the opening angle range of 90°-180° can ensure that the side notch 12 has enough space to accommodate irregular structures, making it easy to quickly insert the motor, and can also stabilize and limit the motor through most of the arc structure of the C-shaped sidewall, taking into account both assembly convenience and operational stability.
[0030] According to the motor mounting structure of this utility model, the mounting base 10 has two snap-fit structures; two mating parts 20 are respectively set on the motor at positions corresponding to the snap-fit structures. Specifically, the two snap-fit structures are symmetrically distributed, such as arranged diagonally at 180° along the axis of the mounting cavity 11, with the corresponding two mating parts 20 set at corresponding positions on the outer wall of the motor, forming a "two-point alignment" fixing mode. Compared with a single snap-fit structure, it can provide balanced clamping force from both sides of the motor, avoiding tilting or offset of the motor due to force on one side, and improving the axial and radial stability of the motor after installation. At the same time, the symmetrical arrangement makes the force more even during motor rotation assembly, and the operator can easily complete the alignment of the mating parts 20 and the snap-fit structures without deliberately adjusting the direction of force, reducing the difficulty of assembly operation. In addition, even if one snap-fit of the double snap-fit structure experiences slight wear due to long-term use, the other snap-fit structure can still maintain its fixing function, extending the service life of the overall mounting structure.
[0031] Furthermore, according to a motor mounting structure of this utility model, the snap-fit structure is provided with a slot opening 14 for the mating part 20 to enter and exit; such as Figure 2 and Figure 4As shown, the slot opening 14 faces either clockwise or counterclockwise. During assembly, after the motor is placed into the mounting cavity 11, it is rotated in the opposite direction to the slot opening 14 so that the mating part 20 is embedded in the slot opening 14. Taking the slot opening 14 facing clockwise as an example, the slot of the snap-fit structure forms a limiting space that is "open clockwise and closed counterclockwise". When the mating part 20 on the motor is initially placed into the mounting cavity 11, it needs to be at the same angle position as the slot opening 14 (i.e., the mating part 20 is aligned with the clockwise slot opening 14). At this time, the mating part 20 can enter the entrance end of the slot opening 14 without obstruction. Then, the motor is rotated counterclockwise (opposite to the direction of the slot opening 14), and the mating part 20 will gradually slide into the depth of the slot along the guide trajectory of the inner wall of the slot until it abuts against the closed end of the slot, forming a stable fit.
[0032] like Figure 3 As shown, according to a motor mounting structure of this utility model, the snap-fit structure includes an elastic pressure plate 15 disposed on the top of the mounting base 10. The elastic pressure plate 15 is bent to clamp the mating part 20 between the end of the elastic pressure plate 15 and the top surface of the mounting base 10. Specifically, the elastic pressure plate 15 is made of a material with a certain elastic deformation capability (such as ABS engineering plastic or elastic metal sheet). Its bent shape is usually "L-shaped" or "arc-shaped". One end is fixedly connected to the top of the mounting base 10 (by means of integral injection molding, screw fastening, etc.), and the other end is a free end that is bent downward, so that a clamping gap is formed between the free end and the top surface of the mounting base 10. The initial width of the gap is slightly smaller than the thickness of the mating part 20. When the mating part 20 enters the gap, the free end of the elastic pressure plate 15 will undergo elastic deformation due to the force, and the gap will expand to accommodate the mating part 20. After the mating part 20 is fully inserted, the elastic pressure plate 15 relies on its own elastic restoring force to apply a continuous clamping force to the mating part 20 through its free end, and firmly clamps the mating part 20 between the end of the elastic pressure plate 15 and the top surface of the mounting base 10, thereby achieving the initial fixation of the mating part 20 and the snap-fit structure. Moreover, the elastic clamping method can avoid the squeezing damage to the mating part 20 caused by the rigid connection.
[0033] Furthermore, according to a motor mounting structure of this utility model, the snap-fit interface further includes a positioning block 16 disposed opposite to the elastic pressure plate 15, the positioning block 16 having a wedge-shaped surface; during assembly, the mating part 20 first passes over the positioning block 16 along the wedge-shaped surface, then enters the space between the elastic pressure plate 15 and the top surface of the mounting base 10, and is clamped by the elastic pressure plate 15. The positioning block 16 is fixed to the top surface of the mounting base 10 and is disposed adjacent to the elastic pressure plate 15, forming a "front-to-back connection" layout in the moving direction of the mating part 20. The positioning block 16 is located in front of the mating part 20 in the entering direction, and the elastic pressure plate 15 is located behind the positioning block 16. During assembly, the operator pushes the mating part 20 along a preset path toward the snap-fit structure. The mating part 20 first contacts the wedge-shaped surface of the positioning block 16 facing itself (this inclined surface gradually slopes upward from the direction of entry of the mating part 20 toward the elastic pressure plate 15). With continuous force, the mating part 20 slides upward along the wedge-shaped surface and passes over the positioning block 16. After passing over the positioning block 16, the mating part 20 directly enters the clamping gap between the rear elastic pressure plate 15 and the top surface of the mounting base 10. At this time, the positioning block 16 forms a block on the other side of the mating part 20 (the side away from the elastic pressure plate 15), and together with the elastic pressure plate 15, it forms a horizontal restriction on the mating part 20, preventing the mating part 20 from shifting or retracting in the horizontal direction. At the same time, after the mating part 20 enters the gap, the free end of the elastic pressure plate 15 applies a downward clamping force to the mating part 20 through its own elastic restoring force, realizing vertical clamping restriction. Finally, through the dual action of "horizontal restriction + vertical clamping", the mating part 20 is ensured to be firmly fixed.
[0034] Furthermore, according to a motor mounting structure of this utility model, the end of the elastic pressure plate 15 facing the positioning block 16 is provided with a raised edge 17 extending obliquely towards the top surface of the mounting base 10. During assembly, after the mating part 20 passes the positioning block 16, it lifts the raised edge 17 to enter between the elastic pressure plate 15 and the top surface of the mounting base 10. Specifically, the raised edge 17 is an oblique structure extending from the free end of the elastic pressure plate 15 towards the positioning block 16, with its extension direction facing away from the top surface of the mounting base 10 (i.e., inclined upwards), forming a guide entrance. When the mating part 20 passes the positioning block 16, its top end first contacts the oblique surface of the raised edge 17. As the mating part 20 continues to move, the oblique surface converts the force of the mating part 20 into a force that causes the free end of the elastic pressure plate 15 to deform upwards, thereby lifting the raised edge 17 and widening the clamping gap between the end of the elastic pressure plate 15 and the top surface of the mounting base 10. The above-described implementation is equivalent to adding a "flared" structure at the clamping gap inlet, which avoids jamming or damage caused by the mating part 20 directly hitting the free end of the elastic pressure plate 15, while reducing the alignment accuracy requirements of the mating part 20 entering the gap and improving assembly convenience.
[0035] Furthermore, such as Figure 1As shown, according to a motor mounting structure of this utility model, the mating part 20 is a plate-shaped structure; wherein, the width of the mating part 20 is adapted to the distance between the positioning block 16 and the elastic pressure plate 15; the thickness of the mating part 20 is less than the maximum distance between the raised edge 17 and the top surface of the mounting base 10, and greater than the minimum distance between the raised edge 17 and the top surface of the mounting base 10. The mating part 20 is designed as a plate-shaped structure, and its width is adapted to the distance between the positioning block 16 and the elastic pressure plate 15 (i.e., the width is slightly less than or equal to the distance), which can adapt to the adjacent layout of the two, prevent the mating part 20 from shifting in the horizontal direction (perpendicular to the direction of the moving path), and ensure that the mating part 20 is always in the center position of the positioning block 16 and the elastic pressure plate 15. The thickness of the mating part 20 is less than the maximum distance between the warped edge 17 and the top surface of the mounting base 10. This is to ensure that the mating part 20 can smoothly lift the warped edge 17 and enter the clamping gap, avoiding the inability to enter due to excessive thickness. The thickness is greater than the minimum distance between the warped edge 17 and the top surface of the mounting base 10. This is to ensure that after the mating part 20 enters the gap, the elastic pressure plate 15 can apply sufficient clamping force to it through its own elastic deformation, preventing the mating part 20 from being clamped insecurely due to insufficient thickness.
[0036] Furthermore, according to a motor mounting structure of this utility model, a limiting hole 21 is provided on the mating part 20; in the assembled state, at least a portion of the elastic pressure plate 15 is inserted into the limiting hole 21 to form a limiting fit. Specifically, the limiting hole 21 is provided in the middle of the plate-shaped mating part 20 or near the side of the elastic pressure plate 15, and its shape is adapted to the shape of the end of the elastic pressure plate 15 (such as round or square); when the mating part 20 is fully inserted into the clamping gap between the elastic pressure plate 15 and the top surface of the mounting base 10, the end of the elastic pressure plate 15 will naturally be inserted into the limiting hole 21 under the action of elastic restoring force, forming a fitting structure. This limiting fit can further enhance the fixing effect. Combined with the horizontal blocking of the positioning block 16, it can completely prevent the mating part 20 from sliding or coming out in the front-back direction; on the other hand, it can limit the vertical movement of the mating part 20, which complements the clamping force of the elastic pressure plate 15. Meanwhile, the presence of the limiting hole 21 can also serve as a signal that the assembly is in place. When the operator feels the end of the elastic pressure plate 15 being stuck in the limiting hole 21, it can be confirmed that the mating part 20 has been assembled in place without the need for additional tools to check, thus improving assembly efficiency and accuracy.
