[0002] The impact resistance of engineering plastic structural components for home appliances refers to the component's ability to resist deformation, cracking, and breakage when subjected to instantaneous external force impact, collision, or vibration.
[0003] In existing technologies, the 90° corners of plastic structural components in household appliances, such as the corners of refrigerator doors, washing machine casings, and the bottom corners of electric kettles, are areas where stress is concentrated during collisions and drops. Accidental drops during daily use, friction and bumps during cleaning, or accidental impacts from children will all directly affect these corner areas. Especially since these corners are rigid edges lacking cushioning structures, the impact force cannot be effectively dispersed, making them highly susceptible to cracking, chipping, and other damage. Therefore, this utility model provides an impact-resistant engineering plastic structural component for household appliances, which solves the above problems through the use of mounting components and elastic components.

[0013] Beneficial effects
[0014] This invention provides an impact-resistant engineering plastic structural component for household appliances. Compared with the prior art, it has the following advantages:
[0015] (1) The impact-resistant engineering plastic structural component for home appliances enhances the protective effect through elastic components. When in use, the L-shaped block is fixed in the placement groove of the L-shaped plate through the mounting components. Multiple sets of arc plates extend naturally under the support of the first spring. When an external object collides with the angle of the L-shaped plate, the internal components of the home appliance first contact the rubber layer of the arc plate. The rubber layer initially buffers the impact force through its own deformation and squeezes the first spring in the corresponding second mounting groove. During the compression of the first spring, the built-in damping rod contracts synchronously, slowing down the compression and rebound speed of the first spring and avoiding secondary impact caused by the rapid rebound of the first spring.
[0016] (2) This impact-resistant engineering plastic structural component for home appliances facilitates the installation and disassembly of the elastic component through the installation assembly. Align the L-shaped block with the L-shaped groove of the L-shaped plate, align the top block with the slot, press the top block, compress the second spring to retract the top block into the receiving groove, place the top block at the bottom of the slot, release the top block, the second spring rebounds and pushes the top block against the inner wall of the slot, the rubber pad fits tightly, and the fixing is completed.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Example:
[0024] Please see Figure 1-3 An impact-resistant engineering plastic structural component for household appliances, comprising:
[0025] L-shaped plate 1, with a placement groove 2 at the included angle of L-shaped plate 1, and an L-shaped block 3 inside the placement groove 2. Both ends of the L-shaped block 3 are provided with mounting components 5, and an elastic component 4 is provided at the included angle of L-shaped block 3. The L-shaped block 3 is located in the placement groove 2 of L-shaped plate 1 and is reinforced by the mounting components 5 at both ends to prevent the elastic component 4 from loosening or shifting during collision or long-term use.
[0026] The elastic component 4 includes a support block 41 and an arc plate 42. One end of the support block 41 is fixedly installed at the angle of the L-shaped block 3. The arc plate 42 is located at the end of the support block 41 away from the L-shaped block 3. A first spring 44 is provided between the arc plate 42 and the support block 41. The arc plate 42 adopts an arc design, which can disperse the impact force through the curved surface during collision and avoid stress concentration. In conjunction with the first spring 44 between the support block 41 and the arc plate 42, the impact energy can be absorbed by the compression deformation of the first spring 44.
[0027] Please see Figure 2 and Figure 4 The placement slot 2 is L-shaped, and slots 6 are provided at both ends of the placement slot 2. The L-shaped block 3 has receiving slots 7 at both ends. The mounting component 5 includes a fixing block 55, which is located inside the upper part of the receiving slot 7. A first mounting slot 8 is provided at the top of the fixing block 55. A second spring 54 is provided inside the first mounting slot 8. A connecting block 52 is provided at the upper end of the second spring 54.
[0028] A top block 51 is fixedly installed on the top of the connecting block 52. A rubber pad 57 is provided on the top wall of the top block 51. A slider 53 is fixedly installed on the side of the connecting block 52. A groove 9 is opened on the side wall of the first mounting groove 8 corresponding to the slider 53. The slider 53 is slidably installed inside the groove 9. The cooperation between the slider 53 and the groove 9 ensures that the connecting block 52 rises and falls smoothly. One end of the second spring 54 is fixedly connected to the bottom wall of the first mounting groove 8, and the other end of the second spring 54 is fixedly installed to the bottom wall of the connecting block 52. The second spring 54 pushes the connecting block 52 to drive the top block 51 to press against the inner wall of the slot 6. The rubber pad 57 enhances the friction and further prevents loosening.
[0029] A first threaded hole 10 is provided on one side of the L-shaped block 3 at the location of the receiving groove 7. A bolt 56 is threaded into the first threaded hole 10. A second threaded hole 11 is provided on one side wall of the fixing block 55 at the location of the first threaded hole 10. The first threaded hole 10 and the second threaded hole 11 have the same diameter. The bolt 56 passes through the first threaded hole 10 and the second threaded hole 11 to fix the fixing block 55 in the receiving groove 7, so as to avoid loosening due to long-term vibration.
[0030] In this embodiment, the installation component 5 facilitates the installation and removal of the elastic component 4. Align the L-shaped block 3 with the L-shaped placement groove 2 of the L-shaped plate 1, align the top block 51 with the slot 6, press the top block 51, compress the second spring 54 to retract the top block 51 into the receiving groove 7, place the top block 51 at the bottom of the slot 6, release the top block 51, the second spring 54 rebounds and pushes the top block 51 against the inner wall of the slot 6, the rubber pad 57 fits tightly, and the fixation is completed. Unscrew the bolt 56, the fixing block 55 moves downward into the receiving groove 7, and the L-shaped block 3 and the elastic component 4 can be directly removed for replacement.
[0031] Please see Figure 2 and Figure 3 The support block 41 has multiple sets of second mounting slots 12 on one end face away from the L-shaped block 3. The first spring 44 is set inside the second mounting slot 12. The first spring 44 is equipped with a damping rod 43. The damping rod 43 suppresses the rebound speed of the first spring 44, avoiding secondary impact caused by the violent rebound of the first spring 44 after impact, and improving the impact energy absorption rate.
[0032] Multiple sets of curved plates 42 are provided. A rubber layer 45 is provided on one side of the curved plate 42. One end of the first spring 44 is fixedly connected to the bottom wall of the curved plate 42, and the other end of the first spring 44 is fixedly installed to the bottom wall of the second mounting groove 12. Multiple sets of curved plates 42 are evenly distributed and cooperate with the second mounting groove 12 of the support block 41 to further improve the protective effect and adapt to different angles. The rubber layer 45 on one side of the curved plate 42 has elasticity and wear resistance. The rubber layer 45 is in direct contact with the colliding object and further buffers the impact force through its own deformation, while avoiding hard friction. The rubber layer 45 can increase the contact friction force.
[0033] In this embodiment, the elastic component 4 enhances the protective effect. During use, the L-shaped block 3 is fixed in the placement groove 2 of the L-shaped plate 1 by the mounting component 5. Multiple sets of arc plates 42 extend naturally under the support of the first spring 44, with the rubber layer 45 exposed on the outside. The first spring 44 is in a naturally extended state, and the damping rod 43 is coaxial with the first spring 44. When an external object collides with the angle of the L-shaped plate 1, the internal components of the appliance first contact the rubber layer 45 of the arc plate 42. The rubber layer 45 initially buffers the impact force through its own deformation. The impact force is transmitted to the arc plate 42, pushing the arc plate 42 to move towards the support block 41 and compressing the first spring 44 in the corresponding second mounting groove 12. During the compression of the first spring 44, the built-in damping rod 43 contracts synchronously. The damping rod 43 consumes the elastic potential energy of the first spring 44, slowing down the compression and rebound speed of the first spring 44 and avoiding secondary impact caused by the rapid rebound of the first spring 44.
