Description

Technical Field

[0001] The invention relates to the technical field of wheel protection covers, and in particular to a wheel protection cover. Background Art

[0002] When existing light trucks are manufactured, exported and sold, various countries have certain requirements on the length of the vehicle's external protrusions to reduce the scratches, scrapes and collisions caused by the vehicle to people outside the vehicle. Among them, the bolts that fix the wheel hub and the bearing end covers are protrusions on the outside of the vehicle, which need to be wrapped or covered, so as to reduce the degree of injury to people in a collision accident between people and vehicles (including collisions when the vehicles are in motion or at rest) and protect people outside the vehicle as much as possible.

[0003] The existing patent (publication number: CN203957696U) discloses a car wheel cover mounting bracket structure, including a wheel cover body and a wheel cover bracket, the wheel cover body is provided with evenly distributed mounting holes, the wheel bracket is connected to the mounting holes, the wheel cover bracket includes a bracket body and fixed base feet connected to both ends of the bracket body, a bolt hole is provided in the center of the bracket body, and the fixed base feet are connected to the bracket body.

[0004] This patent securely fastens the wheel to the wheel bolts by adding a wheel arch bracket, and also evenly distributes the stress exerted on the wheel arch due to road vibration to the entire wheel structure through the wheel arch bracket, thereby reducing the damage to the wheel arch caused by external stress and increasing the overall reliability and safety of the wheel arch.

[0005] However, during the driving of the vehicle, the bearing end cover of the axle may become loose, resulting in oil leakage. However, the existing patent (publication number: CN203957696U) simply covers the bolts that fix the wheel hub, resulting in the driver being unable to intuitively observe the use of the axle bearing end cover, which poses a great safety hazard during the driving of the vehicle. For this reason, we propose a wheel protection cover to solve the above problem. Summary of the invention

[0006] The present invention is intended to provide a wheel protective cover to solve the problem that the use of the axle bearing end cover cannot be directly observed through the automobile wheel cover, which poses a safety hazard.

[0007] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a wheel protective cover, including a wheel cover body and a connecting piece, the wheel cover body is in a circular ring shape, the wheel cover body is used to cover the bolts extending from the wheel, the wheel cover body is provided with a plurality of through holes, and the opening position of each through hole corresponds one by one to the bolts of the wheel hub, a boss is provided at one end of the wheel cover body close to the wheel hub, and the boss corresponds to the bearing end cover of the wheel, a through groove is provided at the top of the boss, a plurality of connecting pieces are provided at one end of the wheel close to the wheel hub, and the connecting pieces are used to connect the wheel cover body and the wheel hub, and the angle between the side face of the wheel cover and the end face of the wheel hub is set to 120°-135°.

[0008] The beneficial effects of this program are:

[0009] 1. The connecting piece fixes the wheel cover body to the front end of the wheel hub through the cooperation of the wheel's own bolts and nuts, and covers the bolts extending from the wheel through the wheel cover body, so that the length of the protrusions on the outside of the vehicle meets the relevant national laws and regulations, thereby reducing the abrasions, scrapes and collisions caused by the vehicle to people outside the vehicle. At the same time, a through groove is opened at the upper end of the boss, which is convenient for the driver to intuitively observe the use of the bearing end cover through the through groove, thereby reducing the safety hazards of the vehicle during driving.

[0010] 2. The boss that sinks into the wheel cover body can reduce the entry of stones or solid debris into the wheel cover body, and prevent the stones from colliding with the bearing end cover inside the wheel cover body, which may cause damage to the bearing end cover. When the stones splash onto the inner wall of the boss, the wheel cover body rotates with the wheel. At this time, the stones rotate out of the boss under the action of the centrifugal force of the boss, thereby protecting the bearing end cover. When the stones enter the wheel cover body through the through hole, the boss can not only prevent the stones from entering the concave cavity of the bearing end cover, but also increase the sound of the stones hitting. When the stones hit the boss, the boss will increase the sound of the stones hitting, so that the driver can promptly discover the stones entering the wheel cover body, thereby reducing the safety hazards during vehicle driving.

[0011] Preferably, as an improvement, the connecting member is arranged in a cross shape, a fixing hole is provided at one end of the connecting member close to the wheel hub, and two supporting points of the connecting member are fixed to the wheel hub by spot welding.

[0012] The beneficial effects are: the connecting piece is set in an "X" shape to increase the contact area between the connecting piece and the wheel cover body, making the connection between the wheel cover body and the wheel hub more stable, and the connecting piece is fixed to the wheel cover body by spot welding, so that the whole formed by the wheel cover body and the connecting piece has higher strength.

[0013] Preferably, as an improvement, the boss is formed by stamping, and the diameter of the through groove is smaller than the diameter of the boss.

[0014] The beneficial effects are: the boss is formed by stamping technology without destroying the overall strength of the wheel cover body, and the diameter of the through groove is smaller than the diameter of the boss, which can further reduce the probability of stones entering the wheel cover body through the through groove, thereby reducing safety hazards during driving.

[0015] Preferably, as an improvement, the connecting members are located at the through holes, and adjacent connecting members are arranged with one through hole between them.

[0016] The beneficial effect is that arranging the connectors at intervals can reduce the installation cost and will not affect the stability of the wheel guard installation.

[0017] Preferably, as an improvement, the angle between the side surface of the wheel cover body and the end surface of the wheel hub is set to 120°-135°.

[0018] The beneficial effect is: by setting the angle between the side of the wheel cover body and the end face of the hub to 120°-135°, the harm caused by flying stones hitting the wheel cover body can be reduced. When the stones hit the side of the wheel cover body, they will slide along the cut surface, thereby reducing damage to the wheel cover body.

[0019] Preferably, as an improvement, the gap between the wheel cover body and the wheel hub is set to 1-2 mm.

[0020] The beneficial effect is: by setting a gap of 1-2mm between the wheel cover body and the wheel hub, the moisture accumulated inside the wheel cover body can be discharged. At the same time, if the gap is set smaller, the wheel cover body and the wheel hub may come into contact due to external foreign matter, causing wear on the surface of the wheel hub and the end face of the wheel cover body, and may also cause a certain degree of abnormal noise during the operation of the vehicle. If the gap is too large, the vehicle may be entangled with foreign matter in certain special operating situations, posing certain traffic hazards.

[0021] Preferably, as an improvement, the edge of the wheel arch body is flanged inwardly.

[0022] The beneficial effect is that by turning over the end surface of the wheel cover body, the end surface of the wheel cover body is prevented from causing damage to pedestrians.

[0023] Preferably, as an improvement, the edges of each through hole are flanged.

[0024] The beneficial effect is that pedestrians are better protected by flanging the edges of each through hole. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The following is further described in detail through specific implementation methods:

[0028] The reference numerals in the drawings of the specification include: wheel cover body 1, through hole 2, boss 3, through groove 4, connecting piece 5, fixing hole 6.

[0029] Example

[0030] The embodiment is basically as shown in the attached Figure 1-2 As shown, Figure 1 The wheel guard shown in the figure comprises a wheel guard body 1 and a connecting member 5. The wheel guard body 1 is in a circular shape and is used to cover the bolts extending from the wheel. The end surface of the wheel guard body 1 is flanged inward. The wheel guard body 1 is provided with 6 through holes 2. The 6 through holes 2 are evenly distributed in a circular shape at the upper end of the wheel guard body 1. The opening position of each through hole 2 corresponds to the bolt of the wheel hub one by one. The edge of each through hole 2 is flanged. Figure 2 The wheel cover body 1 shown has a boss 3 formed by stamping at one end close to the wheel hub, and the boss 3 corresponds to the bearing end cover of the wheel. A through groove 4 is provided at the top of the boss 3, and the diameter of the through groove 4 is smaller than the diameter of the boss 3. In this embodiment, three connecting members 5 are provided, and the three connecting members 5 are fixedly installed at the end of the wheel close to the wheel hub by spot welding, and a through hole 2 is spaced between adjacent connecting members 5. The connecting member 5 is used to connect the wheel cover body 1 and the wheel hub. The connecting member 5 is arranged in a "F" shape, and a fixing hole 6 is provided at the upper end of the connecting member 5, and the two fulcrums of the connecting member 5 are fixed to the wheel hub by spot welding. The bolts of the wheel pass through the fixing holes 6 and are connected to the nuts, thereby fixing the wheel cover body 1 to the surface of the wheel hub, and the three connecting members 5 are fixedly installed between the six through holes 2 at intervals.

[0031] The angle between the side of the wheel cover body 1 and the end face of the wheel hub is set to 120°-135°, which can reduce the harm caused by flying stones hitting the wheel cover body 1. When the stones hit the side of the wheel cover body 1, they will slide along the cut surface, thereby reducing the damage to the wheel cover body 1.

[0032] The gap between the wheel cover body 1 and the wheel hub is set to 1-2mm, which can discharge the moisture accumulated inside the wheel cover body 1. At the same time, if the gap is set smaller, if the gap is too large, foreign objects may be entangled in the gap in some special operating situations of the vehicle, posing certain traffic hazards.

[0033] The specific implementation process is as follows:

[0034] During installation, the staff first unscrews the 6 nuts that fix the wheel, then aligns the 3 connecting parts 5 on the back of the wheel cover body 1 with the 3 bolts of the wheel, and passes the 3 bolts through the fixing holes 6 at the upper ends of the corresponding connecting parts 5 respectively. Finally, the staff uses the corresponding nuts to fix the 6 bolts. At this time, the wheel cover body 1 is fixed to the front end of the wheel hub, and the bolts extending out of the wheel are covered by the wheel cover body 1, so that the length of the protrusions on the outside of the vehicle meets the relevant national laws and regulations, thereby reducing the abrasions, scrapes and collisions of the vehicle to people outside the vehicle. At the same time, the boss 3 is located exactly in the groove of the axle bearing, and the use of the bearing end cover can be intuitively observed through the through groove 4 opened at the upper end of the boss 3, thereby avoiding the situation where the bearing end cover is loose and causes oil leakage without observation, thereby reducing the safety hazard of the vehicle during driving.

[0035] The above is only an embodiment of the present invention, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
