Description

Technical Field

[0001] The utility model relates to the technical field of automobile guard plates, in particular to a lower guard plate for strengthening protection of a motor. Background Art

[0002] The lower guard plate is a protective component for the motor, used to prevent impact from foreign objects at the bottom, intrusion of sand and gravel, and infiltration of water into the motor, thereby extending the motor's service life. However, traditional lower guard plates have certain limitations in terms of motor protection. Traditional lower guard plates lack a partitioned structure and measures to strengthen protection. When encountering high impact situations, the entire lower guard plate will deform, and the undamaged area will also squeeze the motor, weakening the protective effect. Secondly, the temperature of the motor continues to rise under long-term high-load operation. The heat generated by the motor accumulates in the lower guard plate, which cannot be discharged in time, directly threatening the overall life and performance stability of the motor and failing to provide effective protection for the motor. In addition, some external vibrations and impacts can easily cause the lower guard plate to loosen or even fall off, further weakening the protective effect of the lower guard plate on the motor.

[0003] Therefore, it is necessary to design a lower guard plate that strengthens the protection of the motor to solve the problems existing in the current technology. Utility Model Content

DETAILED DESCRIPTION

[0054] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0055] In the description of this application, it should be understood that the terms "center", "up", "down", "front", "front", "left", "right", "vertical", "horizontal", "front", "front", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0056] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. Throughout this application, unless otherwise specified, "plurality" means two or more.

[0057] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0058] See Figure 1-2 As shown, this embodiment provides a lower guard plate for enhanced protection of the motor, including: a guard plate body 1, a baffle 2, a reinforcement rib module, a ventilation module and a limit module, the guard plate body 1 includes: a first guard plate 100, a second guard plate 101 and a third guard plate 102, one end of the second guard plate 101 is fixedly connected to the first guard plate 100, and the other end of the second guard plate 101 is fixedly connected to the third guard plate 102, the first guard plate 100 is fixedly connected to the baffle 2, and the baffle 2 is used to resist flying stones, the first guard plate 100, the second guard plate 101 and the third guard plate 102 are all provided with a reinforcement rib module, and the reinforcement rib module is used to protect the motor, the first guard plate 100, the second guard plate 101 and the third guard plate 102 are all provided with a ventilation module, and the ventilation module is used to guide air circulation, the first guard plate 100 and the third guard plate 102 are both provided with a limit module, and the limit module limits the guard plate body 1.

[0059] Specifically, the protective plate body 1 is the supporting portion of the entire lower guard plate. It is composed of a first guard plate 100, a second guard plate 101, and a third guard plate 102. The second guard plate 101 is located in the middle of the lower guard plate and connects the first guard plate 100 and the third guard plate 102. The first guard plate 100, the second guard plate 101, and the third guard plate 102 together form a stable protective structure. The first guard plate 100 and the third guard plate 102 are located on both sides of the second guard plate 101, providing support and protection. When subjected to external impact, the first guard plate 100, the second guard plate 101, and the third guard plate 102 all have strong shock resistance and deformation resistance, and the deformation of any one guard plate will not affect the protective performance and cause it to decline. The baffle 2 is arc-shaped. When subjected to external impact, the arc-shaped baffle 2 can evenly distribute the force to various parts of the baffle 2, reducing the risk of local force and enhancing the impact resistance of the baffle 2. Its arc-shaped surface causes the splashing objects to rebound in a direction that deviates from the direction when in contact, reducing the possibility of them directly hitting the protective plate body 1. The arc-shaped baffle 2 also has higher structural strength and rigidity, which can better resist deformation, ensuring that the baffle 2 is not easy to bend or deform during long-term use, thereby effectively protecting the motor. The reinforcement rib module further enhances the structural strength of the protective plate body 1, allowing the protective plate body 1 to maintain its structural stability when subjected to strong impact or long-term vibration. The reinforcement rib module evenly disperses the external force it receives, preventing local areas from being subjected to excessive stress, thereby improving the impact resistance of the motor.

[0060] It is understandable that the ventilation module allows air to circulate around the motor, thereby taking away the heat generated by the motor when it is working, and preventing the motor from overheating due to long-term operation. The ventilation module ensures that cold air can effectively enter the interior of the protective plate body 1, while quickly exhausting the hot air, thereby forming a good heat dissipation cycle. The limiting module enhances the stability of the lower guard plate. The limiting module is used to limit the protective plate body 1 so that the protective plate body 1 maintains a corresponding position with the motor and other components, reducing position deviation caused by external vibration, thereby effectively protecting the motor. The synergistic effect of the baffle 2, the reinforcement rib module, the ventilation module and the limiting module enables the lower guard plate to provide all-round motor protection in a complex external environment, thereby improving the reliability and service life of the motor.

[0061] In some examples of the present application, the lower guard plate for strengthening protection of the motor includes: a baffle 2 fixedly connected to a positioning plate 3, the positioning plate 3 has a plurality of first positioning holes 4, and the plurality of first positioning holes 4 are axially symmetrical about the center of the positioning plate 3.

[0062] It is understandable that the baffle 2 is fixedly connected to the positioning plate 3, ensuring that the baffle 2 can always remain in the correct position, so that the baffle 2 will not become loose or displaced due to vibration or impact. There are preferably four first positioning holes 4, and each first positioning hole 4 can be installed with a positioning bolt or a fixing pin to prevent displacement or loosening due to mechanical movement or external impact. The four first positioning holes 4 are symmetrically distributed based on the center of the positioning plate 3. The symmetrical distribution can balance the stress and tension generated during the installation process, so that the positioning plate 3 will not be offset or tilted during the fixing process. In addition, the axially symmetrical positioning holes also provide convenience for the disassembly of the positioning plate 3. When the motor needs to be maintained or parts need to be replaced in daily use, the first positioning holes 4 make it unnecessary to adjust the disassembly angle when disassembling the positioning plate 3, thereby shortening the disassembly time of the positioning plate 3.

[0063] In some examples of the present application, the lower guard plate for strengthening protection of the motor includes: a third guard plate 102 is provided with a plurality of second positioning holes 5 , and the plurality of second positioning holes 5 are axially symmetrical about the center of the third guard plate 102 .

[0064] It can be understood that there are preferably two second positioning holes 5. The double positioning holes reduce the risk of deviation of the third guard plate 102, making it less likely for the third guard plate 102 to tilt or deform when subjected to external force, which helps to improve the reliability of the lower guard plate in protecting the motor during long-term use.

[0065] In some examples of the present application, the lower guard plate for strengthening protection of the motor also includes: a groove module, the groove module includes: a first groove 400, a second groove 401, a third groove 402, a fourth groove 403, a fifth groove 404, a sixth groove 405 and a seventh groove 406, the first guard plate 100 has a first groove 400 and a second groove 401, the third groove 402 is opened in the first guard plate 100, the second guard plate 101 and the third guard plate 102, the fourth groove 403 is opened in the first guard plate 100, the second guard plate 101 and the third guard plate 102, the fifth groove 404 is opened in the first guard plate 100, the second guard plate 101 and the third guard plate 102, the sixth groove 405 is opened in the first guard plate 100, the second guard plate 101 and the third guard plate 102, and the seventh groove 406 is opened in the first guard plate 100, the second guard plate 101 and the third guard plate 102.

[0066] It is understood that the second groove 401 is the shortest, the first groove 400 is longer than the second groove 401, the fourth groove 403 is longer than the first groove 400, the third groove 402 is longer than the fourth groove 403, the seventh groove 406 is longer than the third groove 402, and the fifth groove 404 and the sixth groove 405 are the same length and the longest. The first groove 400, the second groove 401, the third groove 402, the fourth groove 403, the fifth groove 404, the sixth groove 405, and the seventh groove 406 are axially symmetrical about the center of the protective plate body 1. The provision of grooves of different lengths can accommodate the location of motor components of different shapes and sizes, reducing dependence on specific components and improving the compatibility and flexibility of motor protection. Secondly, grooves of different lengths can evenly distribute stress and reduce the impact of single-point stress on the lower guard plate. When subjected to external forces, grooves of different lengths provide more support points, helping to reduce the amplitude of vibration, thereby improving the protective effect. In addition, grooves of different lengths can also reduce the use of metal materials, thereby reducing the overall weight of the lower guard plate and reducing production costs.

[0067] In some examples of the present application, the reinforcement rib module includes: a first reinforcement rib 300, a second reinforcement rib 301, a third reinforcement rib 302, a fourth reinforcement rib 303, a fifth reinforcement rib 304, a sixth reinforcement rib 305 and a seventh reinforcement rib 306, the first reinforcement rib 300 wraps the first groove 400, the second reinforcement rib 301 wraps the second groove 401, the third reinforcement rib 302 wraps the third groove 402, the fourth reinforcement rib 303 wraps the fourth groove 403, the fifth reinforcement rib 304 wraps the fifth groove 404, the sixth reinforcement rib 305 wraps the sixth groove 405, and the seventh reinforcement rib 306 wraps the seventh groove 406.

[0068] Specifically, each rib surrounds its corresponding groove. The second groove 401 is the shortest, and the second rib 301 surrounds the second groove 401. The second rib 301 enhances the support requirements of a small local area and provides preliminary impact resistance during motor protection, maintaining basic stability and support for motor protection. The first rib 300 surrounds the first groove 400. The first rib 300 is longer than the second rib 301. When subjected to external forces, the first rib 300 can more evenly distribute stress, further improving its local compressive strength. The fourth rib 303 is longer than the first rib 300. The fourth rib 303 covers a larger load-bearing area, allowing it to maintain a good structural condition when subjected to stress over a larger area. The third rib 302 is further extended. The longer third rib 302 allows for a larger area of ​​load-bearing and support capacity, and maintains higher stability when subjected to multi-directional forces. The seventh rib 306 is further increased in length, providing better stress distribution. The fifth reinforcing rib 304 and the sixth reinforcing rib 305 are the longest and have the same length. Since their length spans the first guard plate 100, the second guard plate 101 and the third guard plate 102, the fifth reinforcing rib 304 and the sixth reinforcing rib 305 can ensure that the lower guard plate maintains its structural strength under high-frequency vibrations and provide long-lasting and stable protection for the motor.

[0069] It is understood that the first, second, third, fourth, and seventh reinforcing ribs 300, 301, 302, 303, 304, 305, and 306 are axially symmetrical about the center of the guard plate body 1. The different lengths of the grooves and the corresponding reinforcing ribs work together to ensure the multi-layered support and stability of the lower guard plate. Each rib provides a different support force to protect the motor under different stresses, ensuring long-term use of the motor.

[0070] In some examples of the present application, the limiting module includes: a first limiting hole 200, a second limiting hole 201, a third limiting hole 202, a fourth limiting hole 203, a fifth limiting hole 204, a sixth limiting hole 205 and a seventh limiting hole 206, the first guard plate 100 opens the second limiting hole 201, the third limiting hole 202 and the fourth limiting hole 203, and the third guard plate 102 opens the first limiting hole 200, the fifth limiting hole 204, the sixth limiting hole 205 and the seventh limiting hole 206.

[0071] It is understandable that the third limiting hole 202 and the sixth limiting hole 205 have the same aperture, and the first limiting hole 200, the second limiting hole 201, the fourth limiting hole 203, the fifth limiting hole 204 and the seventh limiting hole 206 have the same aperture. The first limiting hole 200, the second limiting hole 201, the third limiting hole 202, the fourth limiting hole 203, the fifth limiting hole 204, the sixth limiting hole 205 and the seventh limiting hole 206 are axially symmetrical about the center of the protective plate body 1. Multiple limiting holes effectively disperse the force points, thereby improving the impact resistance of the motor. The symmetrically distributed limiting holes effectively improve the balance of the installation of the lower guard plate and improve the protection of the lower guard plate to the motor. Limiting holes with different apertures can flexibly install the lower guard plate according to the different positions of the motor to prevent the lower guard plate from mismatching with the motor.

[0072] In some examples of the present application, the ventilation module includes: a first ventilation hole 500, a second ventilation hole 501, a third ventilation hole 502, a fourth ventilation hole 503, a fifth ventilation hole 504 and a sixth ventilation hole 505, the first guard plate 100 opens the first ventilation hole 500, the first guard plate 100 and the second guard plate 101 open the third ventilation hole 502, the third guard plate 102 opens the second ventilation hole 501, the fourth ventilation hole 503 and the fifth ventilation hole 504, and the third guard plate 102, the fifth reinforcement rib 304 and the fifth groove 404 open the sixth ventilation hole 505.

[0073] It is understandable that the first ventilation hole 500 is located on the first guard plate 100, so that air can directly enter the interior of the first guard plate 100. The function of the first ventilation hole 500 is to provide a ventilation path so that external cold air can enter the motor area, achieving a preliminary heat dissipation effect. The third ventilation hole 502 spans the two guard plates. The third ventilation hole 502 can form a ventilation channel between the two guard plates, making the flow of air from the first ventilation hole 500 smoother, effectively improving the heat dissipation efficiency of the motor. At the same time, spanning the two guard plates ensures that the third ventilation hole 502 will not affect the strength and stability of any guard plate. A plurality of ventilation holes are opened on the third guard plate 102. The second ventilation hole 501, the fourth ventilation hole 503 and the fifth ventilation hole 504 are evenly distributed on the third guard plate 102, ensuring that air can effectively circulate inside the third guard plate 102. The second ventilation hole 501 allows cold air to smoothly enter the front area of ​​the third guard plate 102, helping to cool the motor components in this area. The fourth and fifth ventilation holes 503 and 504 allow accumulated motor heat to be quickly dissipated from the rear region. The first, second, third, and fifth ventilation holes 500, 501, 502, and 504 are arranged symmetrically about the center of the protective plate body 1. The sixth ventilation hole 505 is located between the third protective plate 102, the fifth reinforcing rib 304, and the fifth groove 404, ensuring that air can flow not only from within the lower protective plate but also circulate through the fifth reinforcing rib 304 and the fifth groove 404. When the motor is operating at high load, the deep ventilation path can effectively dissipate internal heat, avoiding localized overheating caused by heat accumulation, thereby preventing motor performance degradation or damage due to poor heat dissipation and improving motor protection.

[0074] See Figure 3 As shown, in some examples of the present application, the lower guard plate for strengthening protection of the motor includes: a first guard plate 100 is provided with a plurality of first limiting grooves 6, and the first limiting grooves 6 are axially symmetrical about the center of the first guard plate 100.

[0075] It is understood that the first limiting groove 6 ensures that the first guard plate 100 can be accurately positioned during installation, preventing deviation during installation. There are preferably two first limiting grooves 6, which are distributed on the first guard plate 100 in an axisymmetric manner. When the first guard plate 100 is subjected to external impact, the impact force can be dispersed through the symmetrical first limiting grooves 6, thereby reducing the possibility of damage to the motor and improving the safety of the motor.

[0076] See Figure 4 As shown, in some examples of the present application, the lower guard plate for strengthening protection of the motor includes: a third guard plate 102 is provided with a plurality of second limiting grooves 7, a plurality of second limiting grooves 7 are fixedly connected to limiting protrusions 8, and the limiting protrusions 8 are provided with bolt limiting holes 9.

[0077] It is understood that there are preferably three second limiting grooves 7, each of which is fixedly connected to a limiting protrusion 8. The limiting protrusion 8 not only provides space for bolt installation, but also provides additional support, ensuring the stability of the third guard plate 102 in complex environments and preventing the third guard plate 102 from shifting due to vibration or external impact. The bolt limiting holes 9 opened by the limiting protrusion 8 allow the bolts to pass through the limiting protrusion 8 quickly and accurately during assembly, ensuring a more stable connection of the third guard plate 102 and providing effective protection for the motor.

[0078] In some examples of the present application, the first guard plate 100 is provided with an indicating arrow 10 , and the indicating arrow 10 is used to indicate the installation direction.

[0079] It can be understood that the indicator arrow 10 is axially symmetrical about the center of the first guard plate 100. The indicator arrow 10 is used to clearly indicate the installation direction, ensuring that the direction information can be intuitively conveyed at any angle, reducing misoperation during the installation process, thereby improving installation efficiency and reducing the possibility of failure.

[0080] In summary, the baffle can effectively withstand the impact of flying stones and other foreign objects, protect the motor and its components, and improve the safety of the motor. By setting a reinforcing rib module, the overall structural strength of the lower guard plate can be improved, reducing the risk of deformation and damage under high loads and impacts. By setting the first guard plate, the second guard plate and the third guard plate, the lower guard plate is effectively partitioned, the strength of each guard plate is improved, and the protection of the motor is further strengthened. The ventilation module allows the air inside the lower guard plate to circulate freely, thereby improving the heat dissipation efficiency of the motor and preventing performance degradation or failure due to overheating. The limit module enables the lower guard plate to be stably positioned during installation, avoiding displacement of the lower guard plate due to vibration or impact, thereby maintaining the protective function of the lower guard plate. The protective plate body can adapt to motors of different types and sizes, enhancing the compatibility of motor protection and ensuring that the motor operates in a safe and stable environment.
