[0035] Example 1
[0036] See Figures 1 to 5 As shown, the wheel motor protection device provided in this application includes two protective cover assemblies 101 arranged opposite to each other. The two protective cover assemblies 101 are respectively disposed on the two end faces of the motor to shield the two end faces of the motor, thereby preventing foreign objects such as dust, mud, water and gravel from entering the motor.
[0037] Specifically, the protective cover assembly 101 includes a protective cover 102 and multiple snap-fit members 103. The protective cover 102 faces the end face of the motor to shield it. The area of the protective cover 102 is not less than the area of the end face of the motor, so that the end face of the motor is entirely within the shielding range of the protective cover 102. The protective cover 102 is located on the end face of the motor, preserving heat dissipation channels on the circumferential side of the motor to ensure effective heat dissipation during operation.
[0038] Furthermore, multiple snap-fit pieces 103 are connected to the inner side of the protective cover 102 (the side of the protective cover 102 facing the motor), and the multiple snap-fit pieces 103 are arranged at intervals on the inner side of the protective cover 102. A hub 104 is provided circumferentially around the motor, and the multiple snap-fit pieces 103 are snapped into the inner circumferential surface 105 of the hub; the inner circumferential surface 105 of the hub faces the axle of the wheel. In this way, the protective cover 102 can be installed and fixed on the hub 104 without occupying additional external space, and the protective cover 102 can shield the motor inside the hub 104.
[0039] The wheel motor protection device provided in this application protects the motor by setting a protective cover 102, which improves the appearance and prevents foreign objects such as dust, mud, and gravel from entering the motor, thus extending the motor's lifespan. Furthermore, the protective cover 102 is fixed to the wheel hub 104 around the motor, making reasonable use of the wheel structure and facilitating the installation and removal of the protective cover 102.
[0040] In the optional solutions of this embodiment, such as Figure 3 and Figure 4 As shown, the protective cover assembly 101 also includes a support ring 106; the snap-fit member 103 is provided with an arc-shaped snap-fit groove, and the arc-shaped snap-fit grooves of multiple snap-fit members 103 are located on a preset circumference, the preset circumference is adapted to the circumference of the support ring 106, and the support ring 106 is snapped into the arc-shaped snap-fit grooves of multiple snap-fit members 103.
[0041] In this embodiment, both the protective cover 102 and the snap-fit component 103 are made of plastic and have moderate strength. The support ring 106 is fixed by the arc-shaped groove of the snap-fit component 103, forming a stable circular structure. The supporting effect of the support ring 106 ensures that the snap-fit component 103 fits tightly against the inner circumferential surface 105 of the wheel hub, effectively preventing the protective cover 102 from deforming or loosening due to vibration or external force during use. When installing the wheel motor protection device onto the wheel, the support ring 106 is aligned with the arc-shaped groove of the snap-fit component 103 to assemble the support ring 106 and the protective cover 102. Then, the snap-fit component 103 is snapped into the inner circumferential surface 105 of the wheel hub, completing the installation process, which is simpler and faster.
[0042] In an optional embodiment, the support ring 106 is specifically an elastic steel ring. When the snap-fit member 103 is snapped onto the inner circumferential surface 105 of the wheel hub, the support ring 106 has slight elasticity, allowing it to contract appropriately to facilitate the snap-fit member 103 onto the inner circumferential surface 105 of the wheel hub, thus reducing installation difficulty. The elastic support ring 106 provides a certain tension to ensure that the snap-fit member 103 fits tightly against the inner circumferential surface 105 of the wheel hub. Preferably, the snap-fit member 103 is provided with a snap-fit protrusion 107 facing the inner circumferential surface 105 of the wheel hub, and the inner circumferential surface 105 of the wheel hub is provided with a snap-fit groove 108. The snap-fit protrusion 107 and the snap-fit groove 108 are adapted to each other to make the connection more reliable and prevent loosening.
[0043] In the optional solutions of this embodiment, such as Figure 4As shown, the snap-fit component 103 includes a first snap-fit portion 109 and a second snap-fit portion 110. The first snap-fit portion 109 has a snap-fit protrusion 107 for engaging with the inner circumferential surface 105 of the wheel hub. On a predetermined circumference, both ends of the first snap-fit portion 109 have a second snap-fit portion 110. The first snap-fit portion 109 forms a first groove wall of an arc-shaped groove located on the outer circumference of the support ring 106; the second snap-fit portion 110 forms a second groove wall of an arc-shaped groove located on the inner circumference of the support ring 106. When the support ring 106 is snapped into the arc-shaped groove, the first and second groove walls are misaligned, with the opposite sides of the first and second groove walls open, making it easier to install the support ring 106 into the arc-shaped groove and reducing installation difficulty.
[0044] In an optional embodiment, the first snap-fit portion 109 is provided with a snap fastener 111, which is located at the opening of the arc-shaped slot. A guide ramp is provided on the outer side of the snap fastener 111, allowing the support ring 106 to be inserted into the arc-shaped slot along the guide ramp. The inner side of the snap fastener 111 engages with the support ring 106 to prevent the support ring 106 from disengaging from the arc-shaped slot.
[0045] Example 2
[0046] The wheel motor protection device in this embodiment is an improvement based on the above embodiments. The technical content disclosed in the above embodiments will not be described again, and the content disclosed in the above embodiments also belongs to the content disclosed in this embodiment.
[0047] See Figure 5 As shown, in the optional embodiment, the protective cover 102 includes a cover body 112 and a first cover 113; multiple snap-fit pieces 103 are connected to the inner side of the cover body 112, and the inner side of the cover body 112 faces the motor; the cover body 112 is provided with two symmetrically arranged embedding grooves 114, and the bottom of each embedding groove 114 is provided with a connecting hole 115, and a connector is installed at the connecting hole 115 to connect with the hub 104; the first cover 113 is detachably installed in the embedding groove 114.
[0048] In this embodiment, such as Figure 4As shown, the inner side of the cover 112 is provided with multiple radial reinforcing ribs 116 to increase strength. During installation, the protective cover 102 is first snapped onto the hub 104, and then connected to the hub 104 using bolts or other connecting parts to further improve the reliability of the connection. Since the cover 112 is relatively thin, a connecting post 117 can be provided on the inner side of the cover 112, with a connecting hole 115 penetrating through the cover 112 and the connecting post 117 to increase the connection area and improve connection stability. The support ring 106 is provided with a bent section 118 to avoid the connecting post 117 and the valve stem. To improve the aesthetics of the device, a first cover 113 is used to cover the bolts at the location of the connecting hole 115. Optionally, the first cover 113 is installed in the recess 114 by snapping, and the first cover 113 is flush with the surface of the cover 112, making the overall appearance of the protective cover 102 more integrated and aesthetically pleasing.
[0049] In an optional embodiment, the bottom of the two recessed slots 114 is further provided with a first opening 119, one of which is opposite to the valve stem of the wheel, and the other is symmetrically arranged. When inflating the wheel, it is not necessary to disassemble the entire device; only the first cover 113 needs to be removed to expose the valve stem at the first opening 119, facilitating wheel inflation. The first cover 113 not only covers the connector but also covers the first opening 119 so that the first opening 119 does not affect the appearance of the device. Preferably, the first cover 113 opposite to the valve stem is provided with a mark 120 to help the user identify the position of the valve stem.
[0050] In an optional embodiment, a motor code is provided on one end face of the motor. In the protective cover assembly 102 opposite to this end face, the protective cover 102 further includes a second cover 121. The cover body 112 has a second opening 122, which is opposite to the motor code. The second cover 121 is detachably installed at the second opening 122. Preferably, the second cover 121 is installed at the second opening 122 by a snap-fit mechanism, and the second cover 121 is flush with the surface of the cover body 112, thus enhancing the overall integrity and aesthetics of the protective cover 102. When viewing the motor code, it is not necessary to disassemble the entire device; simply removing the second cover 121 reveals the motor code, making operation more convenient.
[0051] In an optional embodiment, a through hole 123 is provided in the middle of the cover 112, and the through hole 123 is adapted to the structure of the motor shaft 125.
[0052] In this embodiment, such as Figure 1 and Figure 2As shown, for the two end faces of the motor, a brake hub 124 is provided at the center of the shaft 125 of one end face. Therefore, the diameter of the through hole 123 provided in the middle of the cover 112 on that side is larger to expose the brake hub 124. On the other side, only the shaft 125 needs to be exposed at the center of the end face. Therefore, the diameter of the through hole 123 provided in the middle of the cover 112 on that side is smaller. In this way, the protection effect can be maximized without affecting the function of the motor.
