Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to an automobile bumper. Background Art

[0002] Bumpers are installed at both the front and rear ends of cars. Bumpers have the functions of safety protection, vehicle decoration, and improving the aerodynamic characteristics of vehicles. From the perspective of safety, they can play a buffering role in the event of a low-speed collision, protecting the front and rear bodies of the car; they can also play a certain role in protecting pedestrians in the event of an accident with pedestrians. From the perspective of appearance, they are decorative and become an important part of decorating the appearance of cars; at the same time, car bumpers also have a certain aerodynamic effect.

[0003] The front bumper of the car also needs to have the function of mounting the license plate. The existing front bumper of the car usually has a plane in the middle of the front side, and two or four holes are opened on the plane to fix the license plate. However, the existing front bumper of the car has the following disadvantages when in use:

[0004] The license plate can only be fixed by two or four bolts. During the long-term use of the car, the bolts will become loose. When passing through a flooded road, water will enter the air between the license plate and the bumper, providing an outward thrust to the license plate. The car is moving forward, so the water provides an inward pressure on the license plate. Therefore, the reciprocating motion of pushing and pressing will cause the license plate to loosen, fall off and be lost, causing economic losses. If it is not discovered in time and the car continues to drive, it will also lead to important consequences of violating traffic rules and laws. Utility Model Content

[0005] The purpose of the utility model is to solve at least one of the technical defects described in the background technology.

[0006] Therefore, one purpose of the utility model is to provide a car bumper, aiming to solve the problem in the prior art that the license plate on the car bumper is easy to fall off and be lost when the car is driving in wading water.

[0007] In order to achieve the above-mentioned purpose, an embodiment of one aspect of the utility model provides a car bumper, including a bumper body, a ventilation groove is opened on the front side of the bumper body, light grooves are opened on both sides of the top of the bumper body, a license plate box is fixedly connected to the middle part of the bumper body, a hole groove is opened on the front side of the license plate box, a slot is opened on the top of the license plate box, a slide groove is opened on the inner wall of the license plate box, and a mounting hole is opened on the back side of the license plate box.

[0008] Preferably, any of the above schemes has an avoidance groove on the front side of the license plate box to facilitate the special bolts for the license plate to fix the license plate more securely.

[0009] Preferably, any of the above schemes is that an air intake groove is fixedly connected to the top of the inner wall of the bumper body, an air duct is fixedly connected to one side of the air intake groove, a storage groove is fixedly connected to the bottom of the air intake groove, a buoyancy block is slidably inserted inside the storage groove, a limiting strip is fixedly connected to the inner wall of the storage groove, and a connected water guide groove is provided at the bottom of the inner wall of the air intake groove and the inner wall of one side of the storage groove. During wading driving, when the water level in front of the vehicle reaches a certain height, water can enter the storage groove, causing the buoyancy block to float upward, thereby blocking the air intake groove and preventing water from entering the engine. A chamfer is provided on the top of the side of the buoyancy block away from the air duct. During daily driving, after air enters the air intake groove, it can provide downward pressure to the buoyancy block through the chamfered portion, thereby preventing the buoyancy block from rising and blocking the air intake groove, affecting the air intake.

[0010] Preferably, a water inlet groove is provided at the bottom of one side of the storage groove, and a water inlet hole is provided at the bottom of the storage groove. When the vehicle is stationary and is flooded due to rain or other reasons, water can enter the storage groove through the water inlet groove and the storage groove, thereby allowing the air intake groove to be closed in time, preventing water from flooding into the engine and reducing economic losses.

[0011] Compared with the prior art, the advantages and beneficial effects of the utility model are:

[0012] 1. Insert the license plate into the license plate box, and the edge of the license plate is located in the slide groove, so that the edge of the license plate can be limited and fixed. Therefore, when driving through water, it can reduce the amount of water entering the gap between the license plate and the bumper body, thereby avoiding the problem of the license plate falling off and being lost due to the reciprocating pressure and thrust of water on the license plate when driving through water.

[0013] 2. When driving through water, when water enters the air intake groove, the water can enter the storage groove in time through the water guide groove, so that the buoyancy block floats upward, blocking the air intake groove, so that the engine is extinguished in time, and the buoyancy block can prevent water from entering the engine through the air intake groove, thereby avoiding the problem of engine damage caused by driving through water.

[0014] 3. If the engine is turned off while driving through water, there is no water in the engine. Wait until the horizontal plane is relatively still and observe whether the water level is higher than the air intake groove. If it is lower than the air intake groove, you can start the engine again and then drive slowly so that you can get out of trouble in time.

[0015] 4. When the vehicle is driving on a road where the water level is deeper than the air intake groove, the buoyancy block will block the air intake groove in time, causing the engine to shut down. At this time, when the horizontal plane is relatively still, the buoyancy block will still block the air intake groove. At this time, if the driver panics and starts the car a second time, the engine will not be able to start because the buoyancy block blocks the air intake groove, so water will not enter the engine. Therefore, it can avoid the problem of the engine being damaged by inhaling water due to the second start, which will cause the insurance company to refuse compensation.

[0016] 5. When the vehicle is stationary, if a flood occurs, or if the vehicle is submerged above the storage tank due to heavy rain, water can enter the storage tank through the water inlet tank and the water inlet hole in time, so that the buoyancy block rises to block the air inlet tank, thereby preventing water from entering the engine and reducing economic losses to a certain extent.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0025] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] The utility model provides a car bumper.

[0027] Embodiment 1:

[0028] like Figure 1-2 As shown, it includes a bumper body 1, a ventilation slot 11 is provided on the front side of the bumper body 1, light slots 12 are provided on both sides of the top of the bumper body 1, a license plate box 2 is fixedly connected to the middle part of the bumper body 1, a hole slot 21 is provided on the front side of the license plate box 2, the license plate is fixed in the license plate box 2, the hole slot 21 allows the license plate information to be seen from the front side, a slot 22 is provided on the top of the license plate box 2, the license plate can be inserted into the license plate box 2 through the slot 22, a slide slot 23 is provided on the inner wall of the license plate box 2, the edge of the license plate can be inserted into the slide slot 23, so that the license plate will not fall out of the hole slot 21 on the front side, and a mounting hole 24 is provided on the back of the license plate box 2 for connecting with the fixing bolts of the license plate.

[0029] Preferably, an avoidance groove 25 is provided on the front side of the license plate box 2, and the end of the license plate fixing bolt is a round head with a larger diameter, so that the license plate box 2 at the edge of the hole groove 21 will affect the fit between the bolt and the license plate. However, the function of the avoidance groove 25 is to avoid the end of the bolt, ensuring that the head of the bolt can fully fit the license plate, thereby improving the firmness of the license plate fixation.

[0030] Embodiment 2:

[0031] like Figure 1-4As shown, on the basis of Example 1, an air intake groove 3 is fixedly connected to the top of the inner wall of the bumper body 1, and an air guide pipe 31 is fixedly connected to one side of the air intake groove 3. The air guide pipe 31 is used to connect with the air intake pipe of the engine to realize air transportation. A storage groove 32 is fixedly connected to the bottom of the air intake groove 3, and a buoyancy block 4 is slidably inserted inside the storage groove 32. When water enters the storage groove 32, the buoyancy block 4 can slide upward. A limiting strip 33 is fixedly connected to the inner wall of the storage groove 32 to support the buoyancy block 4, so that there is a gap between the bottom of the buoyancy block 4 and the storage groove 32, so that water can hydraulically enter the bottom of the buoyancy block 4. A connected water guide groove 34 is provided at the bottom of the inner wall of the air intake groove 3 and the inner wall of one side of the storage groove 32, so that there is a gap between the buoyancy block 4 and the inner wall of the storage groove 32, which facilitates the entry of water.

[0032] Preferably, Figure 3 As shown, a chamfer 41 is provided on the top of the side of the buoyancy block 4 away from the air guide pipe 31. During normal driving, air quickly enters the air intake groove 3, thereby generating a downward pressure on the buoyancy block 4 through the chamfer 41, thereby ensuring that the buoyancy block 4 is tightly pressed in the storage groove 32, avoiding the problem that air enters the bottom of the storage groove 32 and lifts up the buoyancy block 4, thereby affecting the air intake.

[0033] Embodiment three:

[0034] like Figure 3-4 As shown, on the basis of the second embodiment, a water inlet groove 35 is opened at the bottom of one side of the storage groove 32, and a water inlet hole 36 is opened at the bottom of the storage groove 32. When the vehicle is stationary and the vehicle is soaked in water due to heavy rain or flood, water can enter the storage groove 32 from the bottom of the storage groove 32 through the water inlet groove 35 and the water inlet hole 36 in time, so that the buoyancy block 4 rises and blocks the air intake groove 3 in time, thereby preventing water from entering the engine and reducing economic losses.

[0035] The working principle of the utility model is as follows: when in use, the license plate is fixedly installed in the license plate box 2, so that the slide groove 23 in the license plate box 2 can limit the edge of the license plate, and the auxiliary bolts limit and fix the license plate, thereby avoiding the problem of the license plate falling off due to the reciprocating pressure and thrust of water on the license plate when wading;

[0036] Furthermore, when the vehicle is wading, the bumper body 1 will push the water forward, so that the water level in front of the front bumper is greater than the actual water depth. Therefore, even if the water depth is less than the height of the engine air intake, water may enter the engine through the air intake. The arrangement of the water guide groove 34 in the present application enables the water to enter the storage groove 32 in time through the water guide groove 34 when the water level in front of the bumper body 1 rises when the vehicle is wading, so that the buoyancy block 4 rises quickly to block the air intake groove 3, so that the engine cannot inhale and is extinguished, thereby timely avoiding the problem of the engine being damaged by water ingress.

[0037] After the vehicle is turned off during wading, the vehicle stops and waits until the water becomes still and the water level drops. The water in the storage tank 32 will be discharged through the water inlet tank 35 and the water inlet hole 36, and the buoyancy block 4 will drop. At this time, the engine can be started normally and escape in time. If the water level is higher than the storage tank 32, there will always be water in the storage tank 32, and the buoyancy block 4 will always block the air inlet tank 3. Therefore, if the driver starts the vehicle for the second time in the water, the vehicle cannot be started normally and water will not be sucked into the engine, thereby avoiding the problem of the insurance company not paying compensation for the second water intrusion into the engine due to the driver's misoperation in the wading state.

[0038] Compared with the prior art, the present invention has the following beneficial effects:

[0039] 1. By setting up the license plate box 2, the license plate is inserted into the license plate box 2 through the slot 22 at the top, and the edge of the license plate is located in the slide groove 23, so that the edge of the license plate can be limited and fixed. Therefore, when wading, it can reduce the entry of water into the gap between the license plate and the bumper body 1, thereby avoiding the problem of the license plate falling off and being lost due to the reciprocating pressure and thrust of water on the license plate when wading.

[0040] 2. By setting the buoyancy block 4, when wading, when water enters the air intake groove 3, the water can enter the storage groove 32 in time through the water guide groove 34, so that the buoyancy block 4 floats upward and blocks the air intake groove 3, so that the engine is extinguished in time due to lack of air, and the buoyancy block 4 can prevent water from entering the engine through the air intake groove 3, thereby avoiding the problem of engine damage caused by wading.

[0041] 3. When wading, since the bumper body 1 will push the water forward, the water level in front of the front bumper will be greater than the actual water depth. Therefore, if the engine is turned off in the forward state, no water will enter the engine. Wait until the horizontal plane is relatively still, and observe whether the water level is higher than the air intake groove 3. If it is lower than the air intake groove 3, start the engine again and then drive slowly to get out of trouble in time.

[0042] 4. When the vehicle is traveling on a road where the water level is higher than the air intake groove 3, the buoyancy block 4 will block the air intake groove 3 in time, causing the engine to shut down. At this time, when the horizontal plane is relatively still, the buoyancy block 4 will still block the air intake groove 3. At this time, if the driver panics and starts the vehicle for the second time, the buoyancy block 4 will block the air intake groove 3, making it impossible to start the engine, so that water will not enter the engine. Therefore, it can avoid the problem of the engine being damaged by water due to the second start, which will cause the insurance company to refuse compensation.

[0043] 5. When the vehicle is stationary, if a flood occurs, or if the vehicle is submerged above the receiving tank 32 due to heavy rain, water can enter the receiving tank 32 through the water inlet groove 35 and the water inlet hole 36 in time, so that the buoyancy block 4 rises to block the air inlet groove 3, thereby preventing water from entering the engine and reducing economic losses to a certain extent.
