Description

Technical Field

[0001] The utility model relates to the technical field of wheel protective covers, and particularly relates to a wheel protective cover. Background Art

[0002] When existing light-duty trucks are manufactured and exported for sale, each country has certain requirements for the length of external protrusions of vehicles, which are used to reduce the abrasion, scratch, and collision of vehicles to external personnel. Among them, the bolts and bearing end covers for fixing the wheels are all external protrusions of the vehicle, and it is necessary to wrap or cover them, so as to reduce the degree of injury to personnel in the collision accident between people and vehicles (including collisions when the vehicle is moving or stationary), and protect external personnel as much as possible.

[0003] The existing patent (publication number: CN203957696U) discloses an installation bracket structure for an automobile wheel cover, which includes a wheel cover body and a wheel cover bracket. The wheel cover body is provided with uniformly distributed installation holes, and the wheel cover bracket is connected to the installation holes. The wheel cover bracket includes a bracket body and fixed feet connected to both ends of the bracket body. A bolt hole is provided in the center of the bracket body, and the fixed feet are connected to the bracket body.

[0004] This patent firmly fastens the wheel cover to the wheel bolt by adding a wheel cover bracket, and also evenly disperses the stress exerted on the wheel cover by the vibration of the road surface through the wheel cover bracket to the entire wheel structure, reducing the damage of external stress to the wheel cover and increasing the overall reliability and safety of the wheel cover.

[0005] However, during the driving process of the vehicle, the bearing end cover of the axle may become loose, resulting in oil leakage. However, the existing patent (publication number: CN203957696U) only simply covers the bolts for fixing the wheel hub, resulting in the driver being unable to directly observe the use condition of the axle bearing end cover, and there are relatively large potential safety hazards during the driving process of the vehicle. Therefore, we propose a wheel protective cover to solve the above problems. Content of the Utility Model

[0006] The purpose of the utility model is to provide a wheel protective cover to solve the problem that the use condition of the axle bearing end cover cannot be directly observed by the automobile wheel cover, resulting in potential safety hazards.

[0007] To achieve the above object, the utility model adopts the following technical solution: A wheel protective cover, including a wheel cover body and a connecting member. The wheel cover body is in a circular ring shape and is used to cover the bolts protruding from the wheel. The wheel cover body is provided with a plurality of through holes, and the opening positions of each through hole correspond to the bolts of the wheel hub one by one. One end of the wheel cover body close to the hub is provided with a boss, and the boss corresponds to the bearing end cover of the wheel. A through groove is opened at the top of the boss. One end of the wheel close to the hub is provided with a plurality of connecting members, and the connecting members are used to connect the wheel cover body and the hub. The angle between the side surface of the wheel cover and the end surface of the hub is set to 120°-135°.

[0008] The beneficial effects of this solution are:

[0009] 1. The connecting member fixes the wheel cover body at the front end of the hub through the mutual cooperation of the bolts and nuts of the wheel itself. The bolts protruding from the wheel are covered by the wheel cover body, so that the length of the external protrusions of the vehicle meets the relevant national regulations, thereby reducing the abrasion, scratch and collision of the vehicle to the external personnel. At the same time, a through groove is opened at the upper end of the boss, which is convenient for the driver to directly observe the use condition of the bearing end cover through the through groove, and reduces the potential safety hazards during the driving of the vehicle.

[0010] 2. The boss sunken into the wheel cover body can reduce the entry of stones or solid debris into the wheel cover body, prevent the stones from colliding with the bearing end cover inside the wheel cover body, and cause damage to the bearing end cover. When the stones splash onto the inner wall of the boss, since 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 holes, the boss can not only prevent the stones from entering the concave cavity of the bearing end cover, but also increase the sound when the stones impact. When the stones impact the boss, the boss will increase the sound of the stones colliding, so that the driver can timely find that the stones have entered the wheel cover body, and reduce the potential safety hazards during the driving of the vehicle.

[0011] Preferably, as an improvement, the connecting member is set in a shape of "J", and a fixing hole is opened at one end of the connecting member close to the hub, and the two fulcrums of the connecting member are fixed to the hub by spot welding.

[0012] The beneficial effect is: setting the connecting member in a shape of "J" can increase the contact area between the connecting member and the wheel cover body, make the connection between the wheel cover body and the hub more stable, and fix the connecting member and the wheel cover body by spot welding, so that the whole formed by the wheel cover body and the connecting member has a 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 as follows: The boss is formed by stamping technology, which will not damage the overall strength of the wheel housing body. The diameter of the through groove is smaller than that of the boss, which can further reduce the probability of stones entering the wheel housing body through the through groove and reduce the potential safety hazards during driving.

[0015] Preferably, as an improvement, the connecting member is located at the through hole, and one through hole is provided between adjacent connecting members.

[0016] The beneficial effects are as follows: Arranging the connecting members at intervals can reduce the installation cost and will not affect the installation stability of the wheel guard.

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

[0018] The beneficial effects are as follows: By setting the angle between the side surface of the wheel housing body and the end surface of the wheel hub to 120° - 135°, the harm caused by flying stones hitting the wheel housing body can be reduced. When the stones hit the side surface of the wheel housing body, they will slide along the tangent plane, thereby reducing the damage to the wheel housing body.

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

[0020] The beneficial effects are as follows: By setting a gap of 1 - 2 mm between the wheel housing body and the wheel hub, the accumulated water inside the wheel housing body can be discharged. At the same time, if the gap is set too small, it may cause contact between the wheel housing body and the wheel hub due to external foreign objects, resulting in wear on the surface of the wheel hub and the end surface of the wheel housing body, and may also cause a certain degree of abnormal noise during vehicle operation. If the gap is too large, in some special operating situations of the vehicle, foreign objects may be entangled in this gap, posing a certain traffic hazard.

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

[0022] The beneficial effects are as follows: By flanging the end surface of the wheel housing body, it can prevent the end surface of the wheel housing body from causing harm to pedestrians.

[0023] Preferably, as an improvement, the edges of all through holes are flanged.

[0024] The beneficial effects are as follows: By flanging the edges of all through holes, better protection can be provided for pedestrians. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The reference numerals in the accompanying drawings of the specification include: wheel cover body 1, through holes 2, convex platforms 3, through grooves 4, connecting members 5, and fixing holes 6.

[0029] Embodiment

[0030] The embodiment is basically as shown in the attached Figure 1-2 shown. As Figure 1 shown, a kind of wheel protective cover includes a wheel cover body 1 and a connecting member 5. The wheel cover body 1 is in a circular ring shape. The wheel cover body 1 is used to cover the bolts protruding from the wheel. The end face of the wheel cover body 1 is turned inward. The wheel cover body 1 is provided with 6 through holes 2. The 6 through holes 2 are evenly distributed in a ring shape at the upper end of the wheel cover body 1, and the opening positions of each through hole 2 correspond to the bolts of the wheel hub one by one. The edges of each through hole 2 are all turned inward. As Figure 2 shown, a convex platform 3 formed by stamping is provided at one end of the wheel cover body 1 close to the hub, and the convex platform 3 corresponds to the bearing end cover of the wheel. A through groove 4 is provided at the top of the convex platform 3. The diameter of the through groove 4 is smaller than the diameter of the convex platform 3. In this embodiment, the connecting member 5 is provided with 3. The 3 connecting members 5 are fixedly installed at one end of the wheel close to the hub by spot welding. And there is a through hole 2 between adjacent connecting members 5. The connecting member 5 is used to connect the wheel cover body 1 and the hub. The connecting member 5 is in a shape of "J". 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 hub by spot welding. The bolt of the wheel passes through the fixing hole 6 and is connected with a nut, so as to fix the wheel cover body 1 on the surface of the hub. The 3 connecting members 5 are fixedly installed at intervals between the 6 through holes 2.

[0031] The angle between the side surface of the wheel cover body 1 and the end face of the 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 surface of the wheel cover body 1, they will slide along the tangent plane, thereby reducing the damage to the wheel cover body 1.

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

[0033] The specific implementation process is as follows:

[0034] During installation, the staff first unscrew the six nuts fixing the wheel, then align the three connectors 5 on the back of the wheel cover body 1 with the three bolts of the wheel, and pass the three bolts through the fixing holes 6 at the upper ends of the corresponding connectors 5 respectively. Finally, the staff use the corresponding nuts to fix the six bolts. At this time, the wheel cover body 1 is fixed at the front end of the wheel hub, and the bolts protruding from the wheel are covered by the wheel cover body 1, so that the length of the external protrusions of the vehicle meets the relevant national regulations, thereby reducing the abrasion, scratch and collision of the vehicle to the external personnel. At the same time, the boss 3 is exactly located at the groove of the axle bearing, and the service condition of the bearing end cover can be directly observed through the through groove 4 opened at the upper end of the boss 3, avoiding the situation that the oil leakage caused by the loosening of the bearing end cover cannot be observed, and reducing the potential safety hazard during the driving of the vehicle.

[0035] The above are only the embodiments of the present invention. Specific technical solutions and / or common knowledge such as characteristics well known in the art are not described in detail herein. It should be noted that for those skilled in the art, without departing from the technical solution of the present invention, several deformations and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicality of the patent. The protection scope required by this application should be subject to the content of its claims, and the specific implementation manners described in the specification can be used to interpret the content of the claims.
