Detailed Implementation

[0044] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0045] In this disclosure, unless otherwise stated, directional terms such as "up," "down," "left," "right," "front," and "rear" generally refer to the vehicle's driving state. For example, "up" refers to the direction towards the roof, "down" to the direction towards the bottom, "left" to the direction towards the left door, "right" to the direction towards the right door, "front" to the direction towards the front of the vehicle, and "rear" to the direction towards the rear of the vehicle. "Inner" and "outer" refer to the outline of the component itself. Furthermore, it should be noted that terms such as "first" and "second" are used to distinguish one element from another and do not indicate sequence or importance. Additionally, in the description with reference to the accompanying drawings, the same reference numerals in different drawings denote the same element.

[0046] In related technologies, the front bumper and / or rear bumper of a vehicle are usually decorated with trim panels. These trim panels are typically fixed to the vehicle using plastic clips or screws. Removal requires specialized tools, takes a long time, and can easily damage the trim panels.

[0047] like Figures 1-14 As shown, this disclosure provides a trim panel mounting structure, including a base 1 and a trim panel 2, wherein the base 1 is provided with a locking member 3; the trim panel 2 is provided with a mating part 21, and the locking member 3 includes a locking part 31, the locking part 31 being configured to lock and engage with the mating part 21 as the locking member 3 rotates, so as to lock the trim panel 2 and the base 1, and being able to unlock from the mating part 21 as the locking member 3 rotates, so as to allow the trim panel 2 and the base 1 to separate.

[0048] Through the above technical solution, the trim panel 2 and the base 1 can be separated or locked by rotating the locking component, which makes it easy to quickly remove the trim panel 2 and facilitates the replacement or repair of the trim panel 2.

[0049] To facilitate the insertion and separation of the mating part 21 and the locking part 31, in some feasible embodiments, one of the mating part 21 and the locking part 31 includes a slot, and the other includes a protruding insertion protrusion. The slot and the protruding insertion protrusion are designed to be able to insert or separate from each other as the locking member 3 rotates. For example, the locking part 31 can be a protruding insertion protrusion, and the mating part 21 can be a slot. As the locking member 3 rotates forward, the protruding insertion protrusion inserts into the slot. At this time, the locking part 31 and the mating part 21 are locked and fixed, and the trim panel 2 is fixedly installed on the base 1. As the locking member 3 rotates in the opposite direction, the protruding insertion protrusion separates from the slot. At this time, the locking part 31 and the mating part 21 separate, and the trim panel 2 separates from the base 1. In this way, it is convenient to quickly assemble and disassemble the trim panel 2 from the base 1, and to facilitate the replacement or maintenance of the trim panel 2.

[0050] Of course, the above-described embodiment in which the locking part 31 is a plug-in protrusion and the mating part 21 is a slot is illustrative. In other embodiments, the locking part 31 can also be a slot, and the mating part 21 can be constructed as a plug-in protrusion. When the locking member 3 rotates in the forward direction, the slot of the locking part 31 locks and engages with the plug-in protrusion of the mating part 21, so that the decorative panel 2 is fixedly installed on the base 1. When the locking member 3 rotates in the reverse direction, the slot of the locking part 31 separates from the plug-in protrusion of the mating part 21, so that the decorative panel 2 can be quickly disassembled and assembled from the base 1.

[0051] To make the locking of the mating part 21 and the locking part 31 more reliable when locked, in some feasible ways, such as Figure 3 , Figures 10-13As shown, the locking part 31 includes a plugging protrusion, and the mating part 21 includes a slot that mates with the plugging protrusion. The plugging protrusion is fan-shaped, and the arc-shaped edge of the fan-shaped part mates with the slot. Thus, the rotation of the locking member 3 drives the fan-shaped part to rotate synchronously. The arc-shaped edge of the fan-shaped part can mate with the slot as it rotates synchronously. The fan-shaped part increases the contact area between the locking part 31 and the mating part 21, making the locking part 31 and the mating part 21 more reliable when they are plugged in and locked.

[0052] To facilitate weight reduction while maintaining sufficient structural strength, in some feasible embodiments, the locking part 31 and / or the mating part 21 are provided with a first weight-reducing structure 4 and / or a first reinforcing rib 5. For example, the locking part 31 can be a plug-in protrusion, the mating part 21 can be a slot, the plug-in protrusion is provided with the first weight-reducing structure 4 and the first reinforcing rib 5, the first weight-reducing structure 4 can be a weight-reducing hole / groove, and the first reinforcing rib 5 can be arranged along the extension direction of the plug-in protrusion. This not only reduces the weight of the plug-in protrusion, making it easier for the plug-in protrusion to rotate with the locking member 3, but also ensures that the plug-in protrusion has sufficient strength to ensure stable locking of the plug-in protrusion and the slot through the setting of the first reinforcing rib 5.

[0053] It is understood that the structure of the first weight-reducing structure 4 and the first reinforcing rib 5 on the aforementioned insertion protrusion is illustrative. In other embodiments, the first weight-reducing structure 4 and / or the first reinforcing rib 5 are provided on the slot, and the first weight-reducing structure 4 can be a weight-reducing hole / slot. In addition, the first weight-reducing structure 4 and the first reinforcing rib 5 can also be provided on both the insertion protrusion and the slot according to the working conditions.

[0054] To facilitate the rotation of the locking member 3, in some feasible embodiments, the locking member 3 also includes an actuator 33, which is connected to the locking member 31 to drive the locking member 31 to rotate. The actuator 33 is located on the side of the base 1 away from the trim panel 2. Thus, the arrangement of the actuator 33 does not interfere with the connection between the trim panel 2 and the base 1. Furthermore, when the above-mentioned trim panel mounting structure is applied to the bumper assembly, the side of the base 1 away from the trim panel 2 usually has a large space. Therefore, the actuator 33 can be installed in this space to facilitate operation and improve space utilization.

[0055] The actuating part 33 and the locking part 31 can be rotatably connected to the base 1 via the rotating shaft 32. Thus, by driving the actuating part 33 to drive the rotating shaft 32 to rotate, the locking part 31 can be rotated synchronously to engage or disengage with the mating part 21.

[0056] Optionally, such as Figures 4-7As shown, the trim panel mounting structure also includes a baffle plate 8, which is located above the rotating shaft 32 and fixedly connected to the base 1. The baffle plate 8 is provided with a clearance structure 81, which is used to avoid the rotation trajectory of the actuator 33. The base 1 can be provided with a mounting position for fixed connection with the baffle plate 8. The baffle plate 8 can be fixed to the base 1 by adhesive bonding, screw connection or other fixed connection methods. The clearance structure 81 can be a clearance hole, which is set on the rotation trajectory of the actuator 33. By setting the baffle plate 8, accidental contact with the locking member 3 can be avoided, and the locking member 3 can be prevented from rotating accidentally, which would cause the trim panel 2 to detach from the base 1, thus reducing the risk of accidental detachment of the trim panel 2 from the base 1.

[0057] In some feasible embodiments, in order to adapt to the cover plate 8 and reduce the movement trajectory of the actuator 33, the actuator 33 includes a rotating arm 34. The rotating arm 34 extends in an arc shape, which can reduce the movement range of the rotating arm 34. The first end of the rotating arm 34 is connected to the rotating shaft 32. In the locked state of the locking part 31 and the mating part 21, the second end of the rotating arm 34 is positioned opposite to the avoidance structure 81. When it is necessary to separate the locking part 31 from the mating part 21, the second end of the rotating arm 34 is driven to pass through the avoidance structure 81 to drive the rotating shaft 32 to rotate, thereby driving the locking part 31 to separate from the mating part 21, so that the trim plate 2 can be separated from the base 1, making it easier to replace or repair the trim plate 2. When the locking part 31 needs to be locked with the mating part 21, the second end of the driving rotating arm 34 moves in the opposite direction, thereby driving the first end of the rotating arm 34 to drive the rotating shaft 32 to rotate, thereby driving the locking part 31 connected to the first end of the rotating shaft 32 to rotate synchronously, so as to engage and lock with the mating part 21, so as to fix the trim panel 2 to the base 1.

[0058] To facilitate driving the rotating arm 34, in some feasible ways, such as Figures 9-13 As shown, the second end of the rotating arm 34 is provided with a handle 35. The clearance structure 81 includes a strip hole. There is an operating space between the handle 35 and the edge of the strip hole, which facilitates driving the rotating arm 34 to move according to the set motion trajectory. In the separated state, the handle 35 of the rotating arm 34 is located above the baffle plate 8, and the locking part 31 is separated from the mating part 21. When switching to the locked state, the rotating arm 34 is driven to move, thereby driving the rotating shaft 32 to rotate in the forward direction, driving the locking part 31 and the mating part 21 to insert and lock each other. At this time, the handle 35 extends through the strip hole to the top of the baffle plate 8 or is flush with the upper surface of the baffle plate 8.

[0059] To facilitate the operation of the handle 35 to drive the rotating arm 34, in some feasible embodiments, the handle 35 is provided with a recessed hand groove 36 on the side facing the operating space. The hand groove 36 can accommodate fingers, so that the operator can pull the handle 35 and the rotating arm 34 by inserting part of the fingers into the hand groove 36, thereby locking or disengaging the locking part 31 and the mating part. In some embodiments, it can be designed that when the handle 35 is pulled upward to rotate, it can switch from the locked state to the disengaged state, and when the handle 35 is pressed downward to rotate, it can switch from the disengaged state to the locked state.

[0060] To facilitate assembly, in some feasible embodiments, the rotating arm 34 is plugged into the rotating shaft 32, that is, a plug can be provided at the second end of the rotating shaft 32, and a slot is provided on the rotating arm 34 to mate with the plug. Thus, the rotating arm 34 and the rotating shaft 32 can be detachably connected by plugging and slotting, which facilitates the assembly of the panel-like structure.

[0061] Furthermore, to reduce weight while maintaining sufficient structural strength, in some feasible embodiments, a second weight-reducing structure 6 and / or a second reinforcing rib 7 are provided on the rotating arm 34 and / or the rotating shaft 32. For example, the second weight-reducing structure 6 and the second reinforcing rib 7 can be provided on the rotating arm 34, and similarly on the rotating shaft 32. The second weight-reducing structure 6 can be constructed as a weight-reducing hole / groove, thereby reducing the overall mass of the rotating arm 34 and the rotating shaft 32 while maintaining sufficient structural strength, so as to drive the rotating arm 34 to drive the rotating shaft 32 to rotate in the forward or reverse direction.

[0062] To facilitate the positioning of the decorative panel 2 and the base 1, in some feasible ways, such as Figures 9-14 As shown, a limiting member 9 is provided on the base 1, and a limiting mating part 37 is provided on the actuating part 33. The limiting member 9 and the limiting mating part 37 facilitate the locking of the locking part 31 and the mating part 21. The limiting member 9 connects to the limiting mating part 37 to provide resistance to the actuating part 33 in driving the locking part 31 to rotate and unlock, thereby ensuring the trim panel 2 can be stably installed on the base 1. In some embodiments, when the trim panel 2 needs to be removed, the handle part 35 can be pulled upwards to overcome the resistance provided by the limiting member 9, causing the locking part 31 and the mating part 21 to switch from the locked state to the separated state. Similarly, after switching from the separated state to the locked state, the limiting member 9 and the limiting mating part 37 reconnect.

[0063] Optionally, such as Figure 14As shown, the limiting engagement 37 may include a limiting protrusion, and the limiting member 9 may include two opposing spring portions 91. In the locked state, the limiting protrusion engages between the two spring portions 91. Thus, when the handle portion 35 is pulled up, the limiting protrusion can disengage from the two spring portions 91, and when the handle portion 35 is pressed down, the limiting protrusion can re-insert between the two spring portions 91.

[0064] In some feasible embodiments, to save installation space, the base 1 has a recessed receiving groove 11 on its front sidewall facing the trim panel 2. The receiving groove 11 is used to accommodate at least a portion of the locking part 31 and at least a portion of the mating part 21. Figure 3 As shown, the receiving groove 11 is provided on the front side wall of the base 1 facing the trim panel 2. The locking part 31 and the mating part 21 are both provided in the space of the receiving groove 11. When the trim panel 2 and the base 1 are locked together, the mating part 21 located on the trim panel 2 is placed into the lower part of the receiving groove 11, and the locking part 31 is located in the upper part of the receiving groove 11. Thus, by providing the receiving groove 11, the locking part 31 and the mating part 21 can be integrated into one installation space, which makes it easy for the locking part 31 to rotate and lock or separate from the mating part 21, thereby facilitating the assembly and disassembly of the trim panel 2 and the base 1.

[0065] To improve the stability of the assembly of the trim panel 2 and the base 1, in some feasible embodiments, the locking element 3 and the mating part 21 are arranged in pairs, or multiple pairs of locking elements 3 and mating parts 21 are arranged at intervals. For example... Figure 10 As shown, there are two pairs of locking parts 3 and mating parts 21. The mating parts 21 are spaced apart along the length of the trim panel 2. The locking parts 3 are arranged one-to-one with the corresponding mating parts 21 on the base 1. Thus, the locking state of the trim panel 2 and the base 1 can be made more stable through the cooperation of the two locking parts 3 and the two mating parts 21.

[0066] Of course, it is understood that the structure of the two pairs of locking members 3 and mating parts 21 described above is illustrative. In other embodiments, there may be three or four pairs of locking members 3 and mating parts 21, etc. This disclosure does not specifically limit the quantity.

[0067] A second aspect of this disclosure provides a bumper assembly, such as Figures 1-10As shown, the trim panel mounting structure and bumper 10 are included. The trim panel 2 is supported above the bumper 10, and the locking member 3 and the mating part 21 are arranged near the top of the trim panel 2. The bumper 10 can be a front bumper or a rear bumper. The lower part of the bumper 10 can be fixedly connected to the lower part of the base 1 by screws. For easy installation and positioning, one of the trim panel 2 and the bumper 10 is provided with a positioning part 20, and the other is provided with a positioning mating part 30 that positions and engages with the positioning part 20. For example, the positioning part 20 includes a positioning protrusion, and the positioning mating part 30 includes a positioning groove. There can be multiple positioning protrusions, which are spaced apart along the extension direction of the bottom edge of the trim panel 2. The locking member 3 and the mating part 21 are arranged near the top of the trim panel 2, so that the trim panel 2 can be assembled to the bumper 10 through the positioning protrusion at the bottom end, and locked by the mating part 21 and the locking member 3 to fix the trim panel 2 to the base 1, thereby completing the assembly of the trim panel 2. When the trim panel 2 needs to be removed or replaced, the locking member 3 is rotated to separate the mating part 21 and the locking member 3 on the trim panel 2, and the trim panel 2 can be removed from the bumper 10 by moving the trim panel 2 upward. Furthermore, the fact that the locking member 3 and the mating part 21 are arranged near the top of the trim panel 2 means that the locking member 3 and the mating part 21 are closer to the top of the trim panel 2 than the bottom of the trim panel 2, thereby improving the stability of the trim panel 2 when it is installed on the base.

[0068] The substrate can adopt any suitable structure, such as a bumper mounting frame, etc., and this disclosure does not make any specific limitations in this regard.

[0069] This disclosure provides a vehicle including the aforementioned bumper assembly in a third aspect. It is understood that the vehicle can be any one of a new energy vehicle, a hybrid vehicle, an electric vehicle, or a gasoline-powered vehicle. The trim panel mounting structure provided in the bumper assembly enables quick removal of the trim panel 2, thereby facilitating replacement or repair of the trim panel 2.

[0070] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.

[0071] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0072] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
