Description

Technical Field

[0001] This application relates to the field of automotive parts technology, and in particular to an automotive wheel hub decorative cover, a decorative cover mounting structure, and a wheel hub motor. Background Technology

[0002] A car wheel hub cover is a decorative cover that enhances the aesthetics of the car wheel hub by installing it on the wheel hub, effectively reducing wheel weight and achieving the goal of lightweighting. It also effectively reduces the drag coefficient of the car during operation.

[0003] Currently, wheel cover decorations consist of a cover body and a steel ring that fastens to the cover body. During installation, the steel ring is first aligned with the clips on the wheel hub, and then the cover body is pushed flat to secure the steel ring to the wheel hub. The steel ring provides support for the wheel cover and ensures better contact and fixation between the wheel cover and the wheel hub; however, in existing wheel cover assemblies, the steel ring clips are often not tight enough, which can easily generate noise and cause uneven stress on the wheel cover, leading to deformation. Summary of the Invention

[0004] To address the issue of insufficiently secure installation of the decorative cover and the wheel hub, this application provides an automotive wheel hub decorative cover, a decorative cover mounting structure, and a wheel hub motor.

[0005] On the one hand, the decorative cover mounting structure provided in this application adopts the following technical solution:

[0006] A decorative cover mounting structure includes a fixing seat and a snap-fit ​​seat disposed on the cover body. The fixing seat is provided with a connecting mechanism for fastening the fixing seat to the wheel hub frame. Multiple snap-fit ​​seats are provided. The cover body is provided with an elastic fixing ring connecting the ends of the multiple snap-fit ​​seats away from the cover body. The ends of the multiple snap-fit ​​seats away from the cover body are detachably fastened to the wheel hub frame.

[0007] By adopting the above technical solution, when installing the decorative cover on the wheel hub, multiple snap-fit ​​seats fasten the cover to the wheel hub frame; at the same time, the connecting mechanism secures the fixing seat to the car wheel hub, thereby fixing the decorative cover to the wheel hub frame at multiple points and in multiple parts, thus achieving a firm installation of the decorative cover and the wheel hub.

[0008] Optionally, the connecting mechanism includes a plurality of fixing clips fixed on the fixed base, the fixing clips being provided with a ladder platform adapted to engage with the edge of the wheel hub frame, and the fixed base being provided with an elastic element for driving the ends of the plurality of fixing clips away from the engagement base to spread out from each other.

[0009] By adopting the above technical solution, during the installation of the cover and the wheel hub frame, the cover is pressed towards the wheel hub frame, causing the platform on the fixing clips to gradually pass through the wheel hub frame under pressure. During this process, the fixing clips gradually move closer together under the pressure of the edge of the wheel hub frame, and the elastic elements between the multiple fixing clips are in a compressed state under the pressure of the fixing clips. After the platform passes through the edge of the wheel hub frame, under the restoring force of the elastic elements, the elastic clips drive the ends of the multiple fixing clips away from the fixing seat to separate from each other, thereby making the multiple fixing clips fasten to the edge of the wheel hub frame away from the cover, achieving a stable connection between the cover and the wheel hub frame.

[0010] Optionally, two fixing clips are spaced apart on the fixing base, and the elastic element is a first spring piece disposed between the two fixing clips, with the two ends of the first spring piece respectively abutting against the side of the two fixing clips that are close to each other.

[0011] By adopting the above technical solution, a first spring is set to make the two fixing clips in an outwardly expanded state. When the worker presses the cover, the fixing clips gradually move closer under the pressure of the wheel hub frame edge, and the first spring between the multiple fixing clips is in a compressed state. When the platform on the fixing clip passes the edge of the wheel hub frame, under the action of the restoring force of the first spring, the first spring drives the two fixing clips away from the fixing seat to separate from each other, so that the fixing clips are fastened to the edge of the wheel hub frame away from the cover.

[0012] Optionally, a limiting rod is provided at the middle part of the first spring piece. The limiting rod includes a limiting section, an elastic connecting section fixed to the periphery of both ends of the limiting section, and a fastening section fixed to both ends of the limiting section. The two elastic connecting sections are fixedly connected to both ends of the first spring piece. A positioning rod is rotatably provided on the fixing clip. An insertion groove for the positioning rod to be inserted is provided on the fastening section.

[0013] When the fixing clip is attached to the wheel hub frame, the wheel hub frame presses down on the positioning rod, causing the positioning rod to rotate and insert into the insertion slot.

[0014] By adopting the above technical solution, after the fixing clip is attached to the wheel hub frame, the positioning rod is pressed by the edge of the wheel hub frame, so that the positioning rod rotates and inserts into the insertion groove. At this time, the two positioning rods and the limiting rod are horizontally positioned in the middle of the first spring piece, making it difficult for the first spring piece to be compressed again, thereby realizing the stable connection and fixation between the fixing clip and the wheel hub frame.

[0015] Optionally, the connecting mechanism includes a threaded cylinder fixed on the fixed seat and a positioning bolt threadedly adapted to the threaded cylinder. The head of the positioning bolt is separably pressed against the end face of the hub frame away from the threaded cylinder, and the shank of the positioning bolt is separably threadedly fitted onto the threaded cylinder.

[0016] By adopting the above technical solution, when installing the cover and the wheel hub frame, the positioning bolt is installed on the side of the wheel hub frame away from the decorative cover, so that the head of the positioning bolt is pressed against the end face of the wheel hub frame away from the threaded cylinder, and the threaded part of the rod is assembled on the threaded cylinder, so as to realize the quick installation of the cover and the wheel hub frame.

[0017] Optionally, the connecting mechanism includes a second spring sheet, one end of which is fixedly connected to the fixed seat, and the other end of the fixed seat is provided with a plurality of elastic protrusions, which are elastically engaged in a positioning hole in the wheel hub frame.

[0018] By adopting the above technical solution, a second spring is provided so that the elastic protrusion of the second spring can be directly snapped into the positioning hole of the wheel hub frame, thereby realizing the rapid installation of the cover and the wheel hub frame.

[0019] On the one hand, the automotive wheel hub decorative cover provided in this application adopts the following technical solution:

[0020] A car wheel hub decorative cover includes a cover body with a decorative cover mounting structure.

[0021] By adopting the above technical solution, the cover with the decorative cover installation structure can be stably installed on the car wheel hub frame, which improves the aesthetics of the car wheel hub and effectively reduces the wind resistance when the car is running.

[0022] Optionally, a number of reinforcing strips are fixed on the cover.

[0023] By adopting the above technical solution, reinforcing strips are installed to improve the overall strength of the cover and extend its service life.

[0024] Optionally, the cover is provided with ventilation holes for heat dissipation of the hub motor.

[0025] By adopting the above technical solution, on the one hand, ventilation holes are provided to allow for heat dissipation of the in-wheel motors during vehicle operation, thereby improving the heat dissipation performance of the in-wheel motors. On the other hand, the ventilation holes on the cover effectively reduce the overall weight of the cover, achieving lightweighting.

[0026] On the other hand, this application also provides a hub motor, which adopts the following technical solution:

[0027] A hub motor includes a motor shaft, a stator disposed on the motor shaft, and a rotor rotatably disposed on the outer periphery of the motor shaft for accommodating the stator, and a hub frame detachably connected to the rotor; it also includes an automotive hub decorative cover detachably disposed on the hub frame, and a heat sink fin disposed on the rotor for inserting into the vent holes of the cover.

[0028] By adopting the above technical solution, when the car is running, the rotor of the hub motor drives the hub frame to rotate, thereby realizing the rotation of the car wheels; and during operation, the hub motor is efficiently cooled through heat sinks and vents, effectively improving the heat dissipation performance of the hub motor.

[0029] In summary, this application includes at least one of the following beneficial technical effects:

[0030] 1. Multiple snap-fit ​​seats fasten the cover to the wheel hub frame, and the connecting mechanism secures the fixing seat to the wheel hub frame, thereby fixing the decorative cover to the wheel hub frame at multiple points and in multiple parts, thus achieving a firm installation of the decorative cover and the wheel hub.

[0031] 2. The decorative cover mounting structure can be stably installed on the car wheel hub frame, improving the aesthetics of the car wheel hub and effectively reducing wind resistance during car operation.

[0032] 3. During the operation of the hub motor, efficient heat dissipation is achieved through heat sinks and vents, effectively improving the heat dissipation performance of the hub motor. Attached Figure Description

[0043] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0044] This application discloses a decorative cover mounting structure.

[0045] Example 1:

[0046] Reference Figure 1 and Figure 2 The decorative cover mounting structure includes a fixing seat 11 and a snap-fit ​​seat 12 disposed on the cover body 1. Multiple fixing seats 11 are arranged in a ring at equal intervals on one end face of the cover body 1 in the thickness direction, and the fixing seats 11 are provided with a connecting mechanism for fastening the fixing seats 11 to the wheel hub frame 2. Multiple snap-fit ​​seats 12 are arranged in a ring on the cover body 1, and the cover body 1 is provided with an elastic fixing ring 13 connecting the ends of the multiple snap-fit ​​seats 12 away from the cover body 1. The elastic fixing ring 13 has a notch, and the ends of the multiple snap-fit ​​seats 12 away from the elastic fixing ring 13 are stepped. All multiple snap-fit ​​seats 12 are detachably fastened to the wheel hub frame 2 through the elastic fixing ring 13.

[0047] Reference Figure 3 In this embodiment, the connecting mechanism includes a first connecting component 3, which includes a plurality of fixing clips 31 bonded to the fixing base 11 and an elastic element 32 for driving the plurality of fixing clips 31 away from the fixing base 11 to spread out from each other. In this embodiment, there are two fixing clips 31 on each fixing base 11, and the two fixing clips 31 are fixed to the fixing base 11 at intervals. The ends of the two fixing clips 31 away from the fixing base 11 and away from each other are provided with a stepped platform 3211. The elastic element 32 is a first spring piece 321 or a tension spring that is embedded between the two fixing clips 31. In this embodiment, the first spring piece 321 is preferred. The first spring piece 321 is a U-shaped or W-shaped arc-shaped metal spring piece, and the two ends of the first spring piece 321 are respectively pressed and fixed to the end faces of the two fixing clips 31.

[0048] During the installation of the cover 1 and the wheel hub frame 2, the cover 1 is pressed towards the wheel hub frame 2, causing the fixing clips 31 to be pressed and gradually pass through the wheel hub frame 2. During this process, the fixing clips 31 gradually move closer together under the pressure of the edge of the wheel hub frame 2, so that the first spring piece 321 between the two fixing clips 31 is in a compressed state under the pressure of the fixing clips 31. After the fixing clips 31 pass the edge of the wheel hub frame 2, under the restoring force of the first spring piece 321, the elastic clip drives the multiple fixing clips 31 to separate from each other at the end away from the clip seat 12, so that the multiple fixing clips 31 are fastened to the edge of the wheel hub frame 2 away from the cover 1. At this time, under the limiting of the wheel hub frame 2 on the step 3211 of the fixing clips 31, the multiple fixing seats 11 are difficult to be installed and fall off the wheel hub frame 2, thereby achieving a stable connection between the cover 1 and the wheel hub frame 2.

[0049] The implementation principle of the decorative cover installation structure in this application embodiment is as follows: When installing the cover 1 and the wheel hub frame 2, the cover 1 is pressed towards the wheel hub frame 2 so that multiple snap-fit ​​seats 12 are fastened to the wheel hub frame 2. Then, under the elastic action of the first spring piece 321, multiple fixing clips 31 are fastened to the edge of the wheel hub frame 2 away from the cover 1, thereby realizing a multi-point stable connection between the cover 1 and the wheel hub frame 2.

[0050] Example 2:

[0051] Reference Figure 4 The difference between this embodiment and Embodiment 1 is that the connecting mechanism includes a second connecting component 4. The second connecting component 4 includes a plurality of fixing clips 31 bonded to the fixing base 11, a first spring piece 321 for driving the plurality of fixing clips 31 away from the end of the clip base 12 to spread out from each other, and a limiting rod 41 disposed at the middle part of the first spring piece 321. The limiting rod 41 includes a limiting section 411, elastic connecting sections 412 bonded to the periphery of both ends of the limiting section 411, and a fastening section 413 integrally formed at both ends of the limiting section 411. Both elastic connecting sections 412 are made of elastic metal sheets, and the two elastic connecting sections 412 are fixedly connected to both ends of the first spring piece 321.

[0052] The fixing clip 31 has an installation groove 121 on the side facing the cover 1. The fixing clip 31 is rotatably mounted on the mounting groove 121 via a rotating shaft. The rotation axis of the positioning rod 42 is perpendicular to the length direction of the limiting section 411. The end of the positioning rod 42 away from the rotating shaft is spherical and can rotatably extend out of the mounting groove 121. The first spring piece 321 has a through hole for the positioning rod 42 to pass through on the side facing the positioning rod 42. The fastening section 413 has an insertion groove for the positioning rod 42 to be inserted. During the installation of the cover 1 and the wheel hub frame 2, when the fixing clip 31 is attached to the wheel hub frame 2, the side of the wheel hub frame 2 away from the cover 1 presses the positioning rod 42, so that the positioning rod 42 rotates and inserts into the insertion groove. At this time, the two positioning rods 42 and the limiting rod 41 are horizontally positioned in the middle of the first spring piece 321, making it difficult for the first spring piece 321 to be compressed again, thereby realizing the stable attachment and fixing of the locking seat 12 and the wheel hub frame 2.

[0054] Reference Figure 5 The difference between this embodiment and embodiment one is that the connecting mechanism includes a third connecting component 5. The third connecting component 5 includes a fixing clip 31 and a third spring piece 51 fixedly disposed on the fixing base 11. One end of the third spring piece 51 is engaged with the fixing base 11, and the other end is bent and wrapped around the fixing clip 31. The end of the fixing clip 31 away from the third spring piece 51 is trapezoidal, and the end of the fixing clip 31 away from the third spring piece 51 is elastically engaged with the edge of the wheel hub frame 2.

[0055] Example 4:

[0056] Reference Figure 6 The difference between this embodiment and Embodiment 1 is that the connecting mechanism includes a fourth connecting component 6. The fourth connecting component 6 includes a threaded cylinder 61 fixed on the fixed base 11 and a positioning bolt 62 threadedly adapted to the threaded cylinder 61. The head of the positioning bolt 62 is detachably pressed against the end face of the wheel hub frame 2 away from the threaded cylinder 61. The shank of the positioning bolt 62 passes through a mounting hole on the wheel hub frame 2, and the detachably threaded shank of the positioning bolt 62 is threaded onto the threaded cylinder 61. When installing the cover 1 and the wheel hub frame 2, the positioning bolt 62 is installed on the side of the wheel hub frame 2 away from the decorative cover, so that the head of the positioning bolt 62 presses against the end face of the wheel hub frame 2 away from the threaded cylinder 61, and the shank is threaded onto the threaded cylinder 61, thereby achieving quick installation of the cover 1 and the wheel hub frame 2.

[0057] Example 5:

[0058] Reference Figure 7The difference between this embodiment and Embodiment 1 is that the connecting mechanism includes a fifth connecting component 7, which includes a second spring piece 71. One end of the second spring piece 71 is fitted and fixed or adhesively fixed to the fixing seat 11, and the other end of the fixing seat 11 is bent into two opposing elastic protrusions 711. The two elastic protrusions 711 are elastically engaged with a positioning hole on the wheel hub frame 2. When installing the cover 1, the elastic protrusions 711 of the second spring piece 71 are directly engaged in the positioning hole of the wheel hub frame 2, thereby achieving quick installation of the cover 1 and the wheel hub frame 2.
