Description

Technical Field

[0001] This invention relates to the field of engine mount technology, and more particularly to a quick-lock mount for an automotive engine. Background Technology

[0002] Engine mounts are a type of fastener for automotive engines, mainly divided into two types: torque mounts and engine mounts. Torque mounts are generally installed on the front axle at the front of the car body and connected to the engine, while engine mounts are the main components for fixing shock absorbers. The difference between torque mounts and engine mounts is that engine mounts are rubber blocks that are directly installed on the bottom of the engine, while torque mounts are rod-like structures that are installed on the side of the engine and also have torque mount rubber to absorb shocks.

[0003] Generally, the contact surface between engine mounts and the engine is not cleaned during replacement. However, due to obstructions from various brackets inside the vehicle and the presence of oil and grease around engine parts, it's difficult to achieve a satisfactory level of cleanliness. If dust or oil is present on the contact surface, the mounts will be more prone to wear during use, affecting their cushioning effect. Summary of the Invention

[0004] This invention discloses a quick-lock bracket for automotive engines, which aims to solve the technical problem that if there is dust or oil on the connection surface between the foot pad and the engine, the foot pad will be easily worn during use, affecting the cushioning effect of the foot pad.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A quick-lock bracket for an automotive engine includes an outer sleeve, with multiple side supports fixedly connected at equal intervals around the outer periphery of the outer sleeve, and each side support is provided with a locking mechanism. An outer support is connected to the top of the outer sleeve, and a connecting mechanism is provided at the connection between the outer support and the outer sleeve. A foot rubber body is connected to the center of the inner side of the outer sleeve, and a cleaning mechanism is provided on the inner wall of the outer sleeve, the cleaning mechanism surrounding the outer periphery of the foot rubber body. Multiple connecting holes are provided through one side of the outer support.

[0007] The cleaning mechanism includes multiple L-shaped tubes, which are equidistantly embedded in the outer wall of the outer sleeve. A transition groove is connected to the same end of each L-shaped tube, and an acetone gas inlet pipe is connected to the inner wall of the top of the transition groove. The acetone gas inlet pipe passes through the outer sleeve. An inclined tube is connected to the bottom of each L-shaped tube, and each inclined tube passes through the outer sleeve. A spiral gas delivery pipe is embedded in the inner wall of the outer sleeve, located between the L-shaped tubes and the foot rubber body. Both ends of the spiral gas delivery pipe pass through the top and bottom of the outer sleeve, respectively. One end of the spiral gas delivery pipe is connected to an external air conditioner, and one end of the acetone gas inlet pipe is connected to an external acetone gas generator.

[0008] The bottom end of the outer sleeve is provided with multiple exhaust ports at equal intervals, and the multiple exhaust ports correspond to the bottom ends of multiple inclined tubes respectively. The top and bottom ends of the outer sleeve are respectively provided with cold air inlet and cold air outlet, and the cold air inlet and cold air outlet are respectively connected to the two ends of the spiral air conveying pipe.

[0009] Equipped with a cleaning mechanism, this device is first placed on the existing bracket inside the vehicle. Then, multiple L-shaped tubes spray acetone gas onto the engine side of the footrest body that is attached to it. Since acetone gas can dissolve oil stains, it can simultaneously clean oil stains and dust. Once the device is fully installed, it ensures thorough cleaning of the connection surface between the footrest body and the engine, further reducing wear and damage to the footrest body and ensuring its cushioning effect. At the same time, the cooling effect of the air in the spiral groove cools the inner wall of the entire outer support frame and the surrounding environment of the cleaning area, preventing the use of acetone gas in a high-heat environment and ensuring the safety of acetone gas use.

[0010] In a preferred embodiment, the locking mechanism includes a quick-lock port, with a second slot extending through one side of the quick-lock port. An annular groove is fixedly connected to the bottom end of the quick-lock port. A fifth slot is provided at the bottom end of the side support frame, and the annular groove is located within the fifth slot. A third slot is provided on one side of the fifth slot. A support tube is movably inserted within the quick-lock port, and a second sealing ring is fitted around the outer periphery of the support tube. Slider blocks are fixedly connected to the opposite outer walls of the support tube, and these sliders are movably connected within the second slot. A circular support plate is fixedly connected to the bottom end of the support tube, and a fourth slot is provided at the top end of the circular support plate. The annular groove is located within the fourth slot. An extension plate is fixedly connected to one side of the circular support plate, and a first sealing ring is fixedly connected to the bottom end of the circular support plate.

[0011] With a locking mechanism, multiple quick-lock ports are mainly used for positioning the engine during installation. Multiple bolts on the original bracket inside the vehicle can pass directly through multiple quick-lock ports to determine the installation position of the entire bracket. Based on the setting of the support tube, which serves as a partition between the side support and the original bracket inside the vehicle, sufficient space can be provided for cleaning the exhaust port and cold air outlet. After cleaning, as the extension plate is moved to align with the third slot, the inner wall of the quick-lock port is just squeezed by the second sealing ring. The first sealing ring is set between the circular support plate and the bracket inside the vehicle. Thus, when the bolts are tightened, the tightness of the connection can be optimized.

[0012] In a preferred embodiment, the connecting mechanism includes a spiral tube fixed to the inner wall of the top of the outer support frame. A second through hole is provided inside the spiral tube, and first slots are provided through the opposite sides of the spiral tube. The acetone gas inlet pipe passes through the second through hole, and sliding rods are fixedly connected to the outer walls of the opposite sides of the acetone gas inlet pipe. The sliding rods pass through the first slots. A polygonal outer cover engages with the spiral tube, and the top of the polygonal outer cover is provided with the first through hole. The inner wall of the polygonal outer cover is provided with a spiral groove and an internal thread sequentially from top to bottom, and the internal thread engages with the spiral tube. The sliding rods are movably connected within the spiral groove, and the spiral groove and the internal thread rotate in opposite directions. A sixth slot is provided through the bottom of the polygonal outer cover, and the sixth slot spans the internal thread.

[0013] By incorporating a connecting mechanism, the polygonal outer cover is first fitted onto the outer sleeve through the engagement of the internal thread and the spiral tube. When the outer support frame is attached to the top of the outer sleeve, the sliding rod passes through the first and sixth slots and smoothly enters the spiral groove. Since the spiral groove and the internal thread rotate in opposite directions, the connection between the outer support frame and the outer sleeve can be achieved through the engagement structure of the thread and the structure of the sliding rod pressing down into the spiral groove. Compared with the method of using only threaded connection, this structure maintains the stability of the connection better. At the same time, the setting of the first perforation allows air to circulate at both ends of multiple L-shaped tubes, which can effectively disperse pressure and reduce the direct impact force on the pipe or equipment, thereby assisting the foot rubber body in optimizing the cushioning effect.

[0014] As can be seen from the above, a quick-lock bracket for an automobile engine includes an outer sleeve, a plurality of side supports are fixedly connected at equal intervals around the outer periphery of the outer sleeve, and each side support is provided with a locking mechanism. An outer support is connected to the top of the outer sleeve, and a connecting mechanism is provided at the connection between the outer support and the outer sleeve. A foot rubber body is connected to the center of the inner side of the outer sleeve, and a cleaning mechanism is provided on the inner wall of the outer sleeve. The cleaning mechanism surrounds the outer periphery of the foot rubber body. A plurality of connecting holes are provided through one side of the outer support.

[0015] The cleaning mechanism includes multiple L-shaped tubes, which are equidistantly embedded in the outer wall of the outer sleeve. A transition groove is connected to the same end of each L-shaped tube, and an acetone gas inlet pipe is connected to the inner wall of the top of the transition groove. The acetone gas inlet pipe passes through the outer sleeve. An inclined tube is connected to the bottom of each L-shaped tube, and each inclined tube passes through the outer sleeve. A spiral air supply pipe is embedded in the inner wall of the outer sleeve, located between the L-shaped tubes and the footrest body. The two ends of the spiral air supply pipe pass through the top and bottom of the outer sleeve, respectively. One end of the spiral air supply pipe is connected to an external air conditioner, and one end of the acetone gas inlet pipe is connected to an external acetone gas generator. The automotive engine quick-lock bracket provided by this invention has the technical effect of cleaning the connection surface between the footrest and the engine, ensuring the cushioning effect of the footrest.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0023] The quick-lock bracket for automotive engines disclosed in this invention is mainly used in scenarios involving the installation of quick-lock brackets for engines.

[0024] Reference Figures 1-3 A quick-lock bracket for an automotive engine includes an outer sleeve 6, with multiple side supports 4 fixedly connected at equal intervals around the outer periphery of the outer sleeve 6, and each side support 4 is provided with a locking mechanism 5. An outer support 1 is connected to the top of the outer sleeve 6, and a connecting mechanism 2 is provided at the connection between the outer support 1 and the outer sleeve 6. A foot rubber body 8 is connected to the center of the inner part of the outer sleeve 6, and a cleaning mechanism 3 is provided on the inner wall of the outer sleeve 6. The cleaning mechanism 3 surrounds the outer periphery of the foot rubber body 8. Multiple connecting holes 7 are provided through one side of the outer support 1.

[0025] The cleaning mechanism 3 includes multiple L-shaped tubes 306, which are equidistantly embedded in the outer wall of the outer sleeve 6. A transition groove 305 is connected to the same end of each L-shaped tube 306, and an acetone gas inlet pipe 304 is connected to the inner wall of the top of the transition groove 305. The acetone gas inlet pipe 304 passes through the outer sleeve 6. An inclined tube 307 is connected to the bottom of each L-shaped tube 306, and each inclined tube 307 passes through the outer sleeve 6. A spiral gas delivery pipe 308 is embedded in the inner wall of the outer sleeve 6, located between the L-shaped tubes 306 and the foot rubber body 8. Both ends of the spiral gas delivery pipe 308 pass through the top and bottom of the outer sleeve 6, respectively. One end of the spiral gas delivery pipe 308 is connected to an external air conditioner, and one end of the acetone gas inlet pipe 304 is connected to an external acetone gas generator. When installing this device, it is first placed on the existing bracket inside the vehicle. Then, acetone gas is injected into multiple L-shaped tubes 306 using an external acetone gas generator and sprayed obliquely from the inclined tube 307 onto the engine side of the footrest body 8 that is attached to it. Since acetone gas can dissolve oil stains, the gas spray can simultaneously clean oil stains and dust. When the device is fully installed, it can ensure thorough cleaning of the connection surface between the footrest body 8 and the engine, further ensuring the cushioning effect of the footrest body 8. At the same time, under the action of the spiral groove 203, cold air flows in it and is discharged from the bottom, cooling the inner wall of the entire outer support frame 1 and the surrounding environment of the cleaning position. This can prevent the use of acetone gas in a high-heat environment and ensure the safety of acetone gas use.

[0026] Reference Figure 2 and Figure 3In a preferred embodiment, the bottom end of the outer sleeve 6 is provided with a plurality of exhaust ports 303 at equal intervals, and the plurality of exhaust ports 303 correspond to the bottom ends of a plurality of inclined tubes 307 respectively. The top and bottom ends of the outer sleeve 6 are respectively provided with a cold air inlet 301 and a cold air outlet 302, and the cold air inlet 301 and the cold air outlet 302 are respectively connected to the two ends of the spiral air conveying pipe 308.

[0027] Reference Figure 4 In a preferred embodiment, the locking mechanism 5 includes a quick-locking port 502, and a second slot 501 is provided through one side of the quick-locking port 502. An annular sliding groove 512 is fixedly connected to the bottom end of the quick-locking port 502.

[0028] Reference Figure 4 In a preferred embodiment, the bottom end of the side support 4 is provided with a fifth groove 511, and an annular groove 512 is provided in the fifth groove 511. A third groove 503 is provided on one side of the fifth groove 511.

[0029] Reference Figure 4 In a preferred embodiment, a support tube 510 is movably inserted into the quick-lock opening 502, and a second sealing ring 508 is sleeved on the outer periphery of the support tube 510. Slider 509s are fixedly connected to the outer walls of the opposite sides of the support tube 510, and the slider 509s are movably connected to the second slot 501.

[0030] Reference Figure 4 In a preferred embodiment, a circular support plate 506 is fixedly connected to the bottom end of the support tube 510, and a fourth groove 507 is provided at the top end of the circular support plate 506. An annular groove 512 is located in the fourth groove 507. An extension plate 504 is fixedly connected to one side of the circular support plate 506, and a first sealing ring 505 is fixedly connected to the bottom end of the circular support plate 506. The multiple quick-locking ports 502 are mainly used for positioning with the engine during installation. Multiple bolts on the original bracket in the vehicle can directly pass through the multiple quick-locking ports 502 to determine the installation position of the entire bracket. When the bolt passes through the quick-locking port 502, the slider 509 is engaged with the ring. Within the shaped groove 512, the support tube 510 can serve as a partition between the side support 4 and the existing bracket inside the vehicle, thus providing sufficient space for cleaning the exhaust port 303 and the cold air outlet 302. After cleaning, as the translation extension plate 504 is aligned with the third slot 503, the slider 509 moves upward along the second insertion port 501, and the support tube 510 moves into the quick-lock port 502. The inner wall of the quick-lock port 502 is just squeezed by the second sealing ring 508, and the first sealing ring 505 is set between the circular support plate 506 and the bracket inside the vehicle. Thus, when the bolts are tightened, the tightness of the connection can be optimized.

[0031] Reference Figure 5 In a preferred embodiment, the connecting mechanism 2 includes a screw tube 206, which is fixed to the inner wall of the top of the outer support frame 1. A second through hole 207 is provided in the screw tube 206, and a first slot 205 is provided through the opposite sides of the screw tube 206.

[0032] Reference Figure 5 In a preferred embodiment, the acetone gas inlet pipe 304 passes through the second perforation 207, and the outer walls of the opposite sides of the acetone gas inlet pipe 304 are respectively fixedly connected with slide rods 208, the slide rods 208 pass through the first slot 205, the screw tube 206 is externally engaged with a polygonal outer cover 201, and the top of the polygonal outer cover 201 is provided with a first perforation 202.

[0033] Reference Figure 5 In a preferred embodiment, the inner wall of the polygonal outer cover 201 is provided with a spiral groove 203 and an internal thread 204 sequentially from top to bottom, and the internal thread 204 engages with the screw tube 206. The sliding rod 208 is movably connected in the spiral groove 203, and the spiral groove 203 and the internal thread 204 rotate in opposite directions. The bottom end of the polygonal outer cover 201 is provided with a sixth slot 209, which spans the internal thread 204. In the connecting mechanism 2, the polygonal outer cover 201 is first sleeved on the outside of the screw tube 206 by the engagement of the internal thread 204 and the screw tube 206. When the outer support 1 is spliced ​​on the top of the outer sleeve 6 and fixed to the vehicle bracket through the connecting hole 7, the sliding rod 208 passes through the first slot 205 and the sixth slot 209 and enters the spiral groove 203. The rotation direction of 03 and the internal thread 204 is opposite. At this time, the polygonal outer cover 201 is twisted slightly again to deepen the meshing depth of the internal thread 204 and the screw tube 206. At the same time, under the action of the spiral groove 203, by raising its contact position with the slide rod 208, the slide rod 208 will be driven to rise until it is twisted to the extreme and stops. In this structure, the connection between the outer support 1 and the outer sleeve 6 can be realized through the meshing structure of the thread and the structure of the slide rod 208 pressing down in the spiral groove 203. Compared with the method of using only thread connection, this structure maintains the stability of the connection better. At the same time, through the setting of the first through hole 202, the two ends of multiple L-shaped tubes 306 can be kept in air circulation, which can effectively disperse the pressure and reduce the direct impact force on the pipe or equipment, thereby assisting the foot rubber body 8 to optimize the buffering effect.

[0034] Working principle: When installing this device, first place it on the existing bracket inside the vehicle. Then, use an external acetone gas generator to fill multiple L-shaped tubes 306 with acetone gas, and spray it out obliquely from the inclined tube 307 towards the engine side of the footrest body 8 that is attached to it. Since acetone gas can dissolve oil stains, the gas spray can simultaneously clean oil stains and dust. When the device is fully installed, it can ensure the thorough cleaning of the connection surface between the footrest body 8 and the engine, further ensuring the cushioning effect of the footrest body 8. At the same time, under the action of the spiral groove 203, cold air flows in it and is discharged from the bottom, cooling the inner wall of the entire outer support frame 1 and the surrounding environment of the cleaning position. This can prevent the use of acetone gas in a high-heat environment and ensure the safety of acetone gas use.
