Description

TECHNICAL FIELD

[0001] The utility model relates to vehicle technical field, concretely relates to a sun shield, sun shield assembly and vehicle. BACKGROUND

[0002] In the related art, in order to avoid the sun shield from producing abnormal sound and other faults in the use process, the sliding slot of the sun shield is improved.For example, a sliding slot assembly of a car cover-moving sun shield is provided in the related art, which comprises a cover and a glass mirror, the cover and the glass mirror are installed in the cover-moving body, the cover-moving body is provided with an outer ring and an inner ring, the gap formed by the outer ring and the inner ring is used to install the mirror frame cover;the circumferential outer edge of the mirror frame cover is provided with a female buckle and a guide foot;the circumferential outer edge of the inner ring of the cover-moving body is provided with a male buckle and a positioning slot matched with the female buckle and the guide foot, and the outer edge of the outer ring of the cover-moving body is provided with a buckling foot and a semicircular buckle.The circumferential outer edge of the inner ring of the cover-moving body is provided with the male buckle and the positioning slot matched with the female buckle and the guide foot, so that the assembly effect of the mirror frame cover and the cover-moving body is firm, and the strength is sufficient, so that abnormal sound is not produced.The outer edge of the outer ring of the cover-moving body is provided with the buckling foot and the semicircular buckle, which further prevents abnormal sound.

[0003] However, the above structure involves many components, on the one hand, any slight dimensional deviation may cause the buckle to fail to be smoothly engaged, or the guide foot to fail to accurately enter the positioning slot, thereby affecting the assembly efficiency and product quality.On the other hand, any subsequent design change may require the entire connection structure to be redesigned.Therefore, the above technical means not only increases the production cost, but also produces limitations in manufacturing and assembly. UTILITY MODEL CONTENTS

[0004] The utility model discloses a sun shield, sun shield assembly and vehicle to solve the technical problem that the design of the existing sun shield has limitations.

[0005] In order to achieve the above-mentioned purpose, the technical scheme adopted by the utility model is as follows:

[0006] According to the first aspect of the present application, the present application provides a sun shield, which comprises a sun shield body and a moving cover, the sun shield body is provided with a containing cavity and an opening communicating with the containing cavity and the outside, and the sun shield body is also provided with a sliding slot, the moving cover is slidingly arranged in the sliding slot, the moving cover is used to open or close the opening, the moving cover adopts a pre-deformation design, and a preset included angle is formed between the moving cover and the horizontal plane.

[0007] According to the above technical means, the movable cover in the application adopts a pre-deformation design, reducing the dependence on high-precision assembly of the sun visor. The pre-deformation design can make the movable cover itself adapt to the size deviation of the sliding groove of the sun visor body to a certain extent. For example, even if there is a slight size error in the manufacturing process of the sliding groove, the pre-deformed movable cover can compensate for this error through its own shape change, so as to be more easily installed into the sliding groove, reducing the assembly difficulty and improving the assembly efficiency.

[0008] At the same time, through the pre-deformation design, it is ensured that the movable cover can always maintain a good parallel relationship with the sliding groove under various complex use conditions, thereby ensuring the smoothness of the sliding process of the movable cover. Through the pre-deformation design, the structural weakness caused by the uneven thickness design and the thin-walled design of the movable cover can also be effectively compensated, reducing the possibility of non-parallelism with the sliding groove due to deformation of the movable cover.

[0009] In this way, when the operator operates the movable cover to slide, the movable cover can move uniformly along the sliding groove, avoiding the jamming phenomenon caused by local non-parallelism, and improving the reliability of the product and the experience of the operator. For example, after the car is exposed to the sun for a long time, the temperature in the car rises sharply, and if there is no pre-deformation design, the movable cover may be jammed in the sliding groove and cannot slide normally due to thermal expansion deformation; while the mirror cover with pre-deformation design can still maintain normal sliding function under such conditions.

[0010] In one possible implementation, the sun visor in the application further includes an elastic member connected to the movable cover, and when the movable cover opens at least part of the opening, the elastic member is used to apply an elastic force to the movable cover towards the sliding groove.

[0011] According to the above technical means, the shaking of the movable cover often causes it to collide with the sliding groove or other components, thereby producing abnormal noise. The elastic force provided by the elastic member can always make the movable cover fit on the sliding groove, avoiding the knocking sound or friction sound caused by the loosening of the movable cover.

[0012] In one possible implementation, the elastic member is arranged on the side of the movable cover away from the accommodating cavity, and when the movable cover opens at least part of the opening, the sun visor body extrudes the elastic member in a direction, and the direction of the elastic force is parallel to the first direction, and the first direction is perpendicular to the sliding direction of the movable cover.

[0013] According to the above technical means, during the opening or closing of the movable cover, the elastic force generated by the extrusion of the sun visor body on the elastic member can better play a buffering role. When the movable cover is quickly opened, the elastic member is extruded and deformed, absorbing part of the kinetic energy of the movable cover, slowing down the movement speed of the movable cover, and avoiding violent collision with other components.

[0014] Meanwhile, when the mobile cover needs to be reset, the elastic force can effectively assist it to return to the initial position. Due to the reasonable design of the direction of the elastic force, the elastic force can smoothly push the mobile cover during the closing process of the mobile cover, so that the mobile cover can smoothly slide along the sliding groove and accurately close the opening, thereby improving the reliability and convenience of the operation of the mobile cover.

[0015] In a possible implementation, when the mobile cover closes the opening, part of the elastic member is accommodated in the recess, and the deformation amount of the elastic member is smaller than the deformation amount when the mobile cover opens at least part of the opening.

[0016] According to the above technical means, the deformation amount of the elastic member is larger when the mobile cover opens at least part of the opening, which is to meet various functional requirements in the opening process of the mobile cover. As described above, the larger deformation amount can provide sufficient elastic force to maintain the stability of the mobile cover, buffer the impact force, provide the operation damping feeling, and assist the reset of the mobile cover.

[0017] When the mobile cover closes the opening, the deformation amount of the elastic member is smaller, because the mobile cover is in a relatively stable closed position at this time, and a larger elastic force is not needed to maintain its state as in the opening process. The smaller deformation amount can make the elastic member in a relatively relaxed state but still maintain a certain pre-tightening force, which can not only ensure the stability of the mobile cover in the closed position and prevent it from being accidentally opened (for example, when the vehicle is jolted), but also will not generate excessive pressure on the mobile cover, avoiding excessive extrusion to cause damage to the components or affect the smoothness of the next opening operation.

[0018] In a possible implementation, the recess is a circular arc groove, and the shape of the part of the elastic member matches the recess.

[0019] According to the above technical means, when the mobile cover is opened, the elastic member is extruded to deform, and the semicircular arc recess can make the elastic member bend or compress in a predetermined direction and manner, avoiding irregular deformation of the elastic member, such as twisting or local excessive deformation.

[0020] In a possible implementation, at least one side wall of the sliding groove is provided with a guide slope, and the mobile cover is provided with a matching surface that slides with the guide slope.

[0021] According to the above technical means, the guide slope is arranged on the side wall of the sliding groove, and forms a guide structure with the matching surface of the mobile cover. When the mobile cover slides in the sliding groove, the matching surface moves along the guide slope, which can ensure that the mobile cover always maintains the correct direction during the sliding process.

[0022] In a possible implementation, the matching surface and the guide slope are in linear contact.

[0023] According to the above technical means, when the fitting surface of the moving cover is in linear contact with the guide inclined surface of the sliding groove, the friction force received by the moving cover during sliding is greatly reduced, thereby achieving a more smooth sliding effect. When operating the moving cover, the operator can obviously feel that less force is required for pushing or pulling, and the operation feels more light and smooth, greatly improving the convenience and comfort of using the sun visor.

[0024] According to the second aspect of the present application, a sun visor assembly is provided, which comprises the sun visor and the lens described above. The accommodation cavity is further provided with an accommodation groove, which is arranged on the side of the sliding groove away from the moving cover. The lens is accommodated in the accommodation groove, and the lens is in linear contact with the accommodation groove. In the thickness direction of the moving cover, the projection of the opening on the plane where the lens is located at least partially overlaps the projection of the lens on the plane where the lens is located.

[0025] According to the above technical means, by arranging the accommodation groove in the accommodation cavity and arranging it on the side of the sliding groove away from the moving cover, efficient use of the space of the accommodation cavity is achieved. This layout fully considers the functions and mutual relationships of the components, and reasonably arranges different components in a limited space. When the user opens or closes the moving cover, slight vibration or shaking of the area where the lens is located may occur. The linear contact between the lens and the accommodation groove makes the friction generated in this case very small, and the lens can move or remain stationary in the accommodation groove more smoothly, reducing the abnormal noise generated by friction, and also avoiding damage such as scratches on the surface of the lens caused by excessive friction.

[0026] Both the moving cover can smoothly slide on the sliding groove to realize the opening and closing function of the opening, and the lens is provided with a special placement position, avoiding space conflicts between components, making the structure of the entire sun visor assembly more compact, meeting the requirements of space compactness of automotive interior components, and helping to enrich the functional configuration of the sun visor without increasing the overall volume.

[0027] In a possible implementation, the sun visor assembly in the present application further comprises a micro switch, which is arranged in the accommodation cavity. When the moving cover opens at least part of the opening, the moving cover is used to contact the micro switch, and the micro switch is a silent switch.

[0028] According to the above technical means, the sun visor assembly can automatically switch the related functions of the sun visor assembly through the micro switch according to the opening state of the moving cover. At the same time, in the use environment of vehicles and the like, the use of the silent switch can avoid noise caused by the triggering of the micro switch during the opening or closing of the moving cover.

[0029] According to the third aspect of the present application, a vehicle is provided, which comprises the sun visor assembly described above.

[0030] According to the above technical means, the overall quality of the vehicle interior is greatly improved, and the comfort of the passengers during the ride is improved.

[0031] The utility model discloses the beneficial effects of:

[0032] (1) the mobile cover in the application adopts predeformation design, is arranged in the sliding slot and is assisted movement by the elastic piece, makes sun visor opening and closing operation more flexible, and the sun visor angle and range are adjusted as required for the convenience of the driver and passenger.

[0033] (2) the sun visor assembly structure in the application has good compatibility and adaptability, can cope with different size changes, vibration environment and the like, and can normally play a role under various vehicle use scenes (daily commuting, long-distance travel, different road conditions and the like), and the overall practicality and universality of the vehicle are improved.

[0034] It should be noted that the technical effects brought by the implementation manners of the second aspect to the third aspect can be referred to the technical effects brought by the corresponding implementation manners in the first aspect, which will not be repeated here.

DETAILED DESCRIPTION

[0045] In order for those skilled in the art to better understand the technical solutions of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings.

[0046] It should be noted that the terms "first", "second", and the like in the specification and claims of the present application and the above-described drawings are used to distinguish similar objects, and do not necessarily have to describe a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0047] The embodiments of the present application provide a vehicle. Wherein, the embodiments of the present application do not make specific limitation to the specific type of the vehicle, for example, the vehicle provided by the embodiments of the present application can be an electric vehicle, a hybrid vehicle or a solar vehicle, etc. Meanwhile, the vehicle provided by the embodiments of the present application can also be a vehicle in different forms. For example, the vehicle provided by the embodiments of the present application can be a sedan, a sport utility vehicle (SUV) or a multi-Purpose Vehicles (MPV).

[0048] In some embodiments, the vehicle in the present application includes a sun visor assembly, which includes a sun visor. During the driving process of the vehicle, when the sunlight directly shines from the windshield, the driver or passenger can turn down the sun visor to block the sunlight, avoid the glare of strong light, and ensure the safety of driving and the comfort of riding, especially during the period of driving against the sun, such as in the morning or evening, which is particularly obvious.

[0049] In some embodiments, referring to Figure 1 , Figure 2 and in conjunction with Figure 3The sun visor in the present application comprises a sun visor body 100 and a moving cover 200. The sun visor body 100 is provided with a receiving cavity and an opening 102 communicating with the outside world. The sun visor body 100 is also provided with a sliding groove 1012. The moving cover 200 is slidingly arranged in the sliding groove 1012. The moving cover 200 is used to open or close the opening 102. The moving cover 200 adopts a pre-deformation design. A preset angle a is formed between the moving cover 200 and the horizontal plane.

[0050] In the vehicle use environment, the moving cover 200 may be deformed by various factors.

[0051] For example, temperature changes will cause materials to expand and contract with heat. The temperature in the vehicle fluctuates greatly, especially in different seasons and different driving conditions, from high temperature exposure to low temperature environment, or from cold outdoor to warm indoor. The volume of the material will change. In addition, during the long-term use process, it may be subjected to external pressure, vibration and other mechanical actions. If the moving cover 200 is designed with unequal thickness or thin-walled design (2mm or less), the relatively thin part of the structure is more likely to be affected by these factors and change shape.

[0052] Pre-deformation design is a strategy of pre-adjusting the shape of the product. Through accurate calculation and design, the moving cover 200 has a certain shape deviation in the initial state. The deviation is opposite to the deformation direction and similar in size to the actual deformation. When the product is deformed by temperature changes, external forces and other factors, the pre-designed deformation can offset or partially offset the actual deformation, so that the moving cover 200 can maintain a parallel state with the sliding groove 1012 as a whole. In this way, during the sliding process, each part of the moving cover 200 can move uniformly along the sliding groove 1012, avoiding interference with the sliding groove 1012 due to local non-parallelism, thereby effectively preventing the occurrence of jamming and ensuring smooth sliding.

[0053] Referring to Figure 2 , in combination with the present application, the deformation position of the moving cover 200 is the B curve shown in Figure 2 , and the target position of the moving cover 200 is the A curve shown in Figure 2 . The pre-deformation design of the moving cover 200 means that the moving cover 200 is deformed in advance on the side away from the target position of the deformation position. The angle formed by the deformation is the preset angle a, and the deformation position is symmetric to the moving cover 200 with the target position as the center. In this way, when the moving cover 200 deforms, it deforms towards the target position and eventually reaches the A curve where the target position is located.

[0054] For example, the preset angle a is 5°. Of course, with different sizes and different needs of the moving cover 200, the preset angle a in the present application will change accordingly.

[0055] It should be noted that the sliding groove 1012 in the present application can be arranged in the accommodating cavity or on the surface of the sun visor body 100, which is not limited in the present application. For the convenience of description, the sliding groove 1012 arranged in the accommodating cavity is taken as an example for illustrative description.

[0056] In some embodiments, continuing to refer to Figure 1 and combining Figure 5 , the sun visor in the present application further comprises a fixing member 101 arranged in the accommodating cavity, the fixing member 101 forms an accommodating space 1011 for accommodating components such as the lens 400 in the sun visor. At the same time, the wall surface of the fixing member 101 forms a continuous sliding groove 1012, so that the moving cover 200 can slide uninterruptedly.

[0057] In some embodiments, continuing to refer to Figure 1 and combining Figure 3 , the sun visor in the present application further comprises an elastic member 300 connected to the moving cover 200, when the moving cover 200 opens at least part of the opening 102, the elastic member 300 is used to apply an elastic force to the moving cover 200 towards the sliding groove 1012.

[0058] On this basis, when the moving cover 200 opens at least part of the opening 102, the elastic member 300 applies an elastic force to the moving cover 200 towards the sliding groove 1012, so that the moving cover 200 maintains close contact with the sliding groove 1012 in the open state, which can effectively inhibit the shaking or deviation of the moving cover 200 due to vibration and other reasons during the driving of the vehicle, and ensure the relative stability of the position of the moving cover 200, so that it is always on the correct sliding track.

[0059] At the same time, the elastic member 300 generates resistance during the movement of the moving cover 200, giving the operator a moderate damping feeling. When the operator opens or closes the moving cover 200, he or she will not feel that the moving cover 200 is too loose or too tight, but will have a smooth and certain feedback operation feeling, which improves the comfort and quality of the operation.

[0060] In some embodiments, continuing to refer to Figure 1 and combining Figure 4 , the elastic member 300 is arranged on the side of the moving cover 200 away from the accommodating cavity, when the moving cover 200 opens at least part of the opening 102, the sun visor body 100 extrudes the elastic member 300 in the first direction, the direction of the elastic force is parallel to the first direction; the first direction is perpendicular to the sliding direction of the moving cover 200, and the first direction is perpendicular to the thickness direction of the moving cover 200.

[0061] It should be noted that the first direction exemplified in the present application is only a direction shown as an example and does not constitute a limitation on the scheme in the present application.

[0062] On this basis, the elastic member 300 is arranged on the side of the moving cover 200 away from the accommodating cavity, and the relatively spacious external space around the sun visor body 100 is ingeniously utilized. Such a layout avoids arranging the elastic member 300 in the limited space inside the accommodating cavity, so that the accommodating cavity can be more focused on placing other important components such as the lens 400, and the space planning inside the entire sun visor is more reasonable and compact, reducing the risk of space interference between components.

[0063] The elastic force is perpendicular to the sliding direction and the thickness direction of the moving cover 200, providing a lateral stabilizing support force for the moving cover 200. During the sliding process of the moving cover 200, even if disturbed by vehicle vibration, external force collision and other factors, the lateral force can accurately "restrain" the moving cover 200 in the correct position, preventing it from appearing lateral deviation, up and down jumping and other unstable conditions, and ensuring that the moving cover 200 always slides smoothly and stably along the sliding groove 1012, just like installing a lateral "track guide" for the moving cover 200.

[0064] Due to the reasonable setting of the direction of the elastic force, when the operator operates the moving cover 200 to open or close, a smoother and more textured operation experience can be felt. The elastic force does not hinder the normal sliding of the moving cover 200 or cause a sense of jamming, but provides a smooth resistance feedback just right, so that the operator feels that the opening and closing of the moving cover 200 is both easy and not lacking in control during the operation process, improving the comfort and satisfaction of the operator's operation.

[0065] In some embodiments, continuing to refer to Figure 1 and combining Figure 3 , the sliding groove 1012 is provided with a recessed portion 1012a, when the moving cover 200 closes the opening 102, part of the elastic member 300 is accommodated in the recessed portion 1012a, and the deformation amount of the elastic member 300 is less than the deformation amount when the moving cover 200 opens at least part of the opening 102.

[0066] The larger deformation amount of the elastic member 300 when the moving cover 200 opens at least part of the opening 102 is to meet various functional requirements during the opening process of the moving cover 200, such as providing sufficient elastic force to maintain the stability of the moving cover 200, buffering impact force, providing operation damping feeling, and assisting the resetting of the moving cover 200, etc.

[0067] When the moving cover 200 closes the opening 102, the deformation amount decreases because the moving cover 200 is in a relatively stable closed position and does not need as much elastic force as in the opening process to maintain its state. The smaller deformation amount not only ensures the stability of the moving cover 200 in the closed position and prevents it from being accidentally opened (for example, when the vehicle is jolted), but also does not generate excessive pressure on the moving cover 200, avoiding excessive extrusion that can damage the components or affect the smoothness of the next opening operation. Thus, the moving cover 200 is properly supported by the elastic force in different operation stages, optimizing the entire operation process.

[0068] In some embodiments, continuing to refer to Figure 1 and combining Figure 3 , the recess 1012a is a circular arc groove, and the shape of the part of the elastic member 300 matches the circular arc groove.

[0069] On this basis, when the sun visor is subjected to external forces during use, for example, the opening and closing operation of the moving cover 200 causes the elastic member 300 to be stressed, the circular arc groove and the matching elastic member 300 can evenly distribute the force on the contact surface.

[0070] Specifically, when the moving cover 200 is in a closed state, the elastic member 300 is partially accommodated in the circular arc groove, and the shapes of the two match. In the initial stage of opening the moving cover 200, this matching can provide precise guidance for the elastic member 300. During the opening of the moving cover 200, the matching of the circular arc groove and the elastic member 300 enables the elastic force to be more evenly transmitted to the moving cover 200. Since the contact surface of the elastic member 300 and the circular arc groove is closely matched and shaped, when the elastic member 300 is deformed to generate elastic force, the force can be evenly applied to the moving cover 200 through the entire contact surface, rather than being concentrated in certain points or areas. This avoids problems such as tilting, jamming, or increased friction with the sliding groove 1012 of the moving cover 200 due to excessive local stress, thereby making the opening of the moving cover 200 smoother and easier.

[0071] In addition, during the opening of the moving cover 200 by the operator, the matching of the circular arc groove and the elastic member 300 can provide a comfortable damping feeling for the operator. The deformation of the elastic member 300 in the circular arc groove and the transmission of the elastic force is a gradual process, and the operator will feel a smooth and moderate resistance feedback when operating the moving cover 200.

[0072] In some embodiments, referring to Figure 5 and combining Figure 6 , at least one side wall of the sliding groove 1012 is provided with a guide inclined surface 1021b, and the moving cover 200 is provided with a matching surface 201 that matches and slides with the guide inclined surface 1021b.

[0073] Based on this, the engagement between the guide ramp 1021b and the mating surface 201 provides clear and precise guidance for the sliding of the movable cover 200 within the slide groove 1012. During long-term use of the movable cover 200, the components may experience some wear or slight deformation, but due to the guiding effect of the guide ramp 1021b and the mating surface 201, the movable cover 200 can still maintain the correct sliding posture.

[0074] In some embodiments, see Figure 5 and combined Figure 6 The mating surface 201 and the guide inclined surface 1021b are in linear contact.

[0075] It is understandable that when the mating surface 201 of the movable cover 200 is in linear contact with the guide slope 1021b of the slide groove 1012, the friction force experienced by the movable cover 200 during the sliding process is significantly reduced, thereby achieving a smoother sliding effect.

[0076] Based on this, when operating the movable cover 200, users can clearly feel that less force is required to push or pull it, and the operation is lighter and smoother, which greatly improves the convenience and comfort of using the sun visor.

[0077] In some embodiments, see Figure 1 and combined Figure 5 The sun visor assembly in this application also includes a lens 400, and the accommodating cavity is further provided with an accommodating groove 1013. The accommodating groove 1013 is located on the side of the slide groove 1012 away from the movable cover 200, so as to reasonably arrange different components within the limited accommodating cavity, realize the functions of each component, and avoid spatial conflicts.

[0078] The lens 400 is housed in the receiving groove 1013, and the lens 400 is in line contact with the receiving groove 1013. Along the thickness direction of the movable cover 200, the projection of the opening 102 on the plane where the lens 400 is located at least partially coincides with the projection of the lens 400 on the plane where the lens 400 is located.

[0079] The projection of the opening 102 onto the plane of the lens 400 along the thickness direction of the movable cover 200 is at least partially coincident with the projection of the lens 400 onto the plane of the lens 400. This is to ensure that when the movable cover 200 is opened, the operator can see the lens 400 through the opening 102, thereby facilitating the use of the lens 400 for grooming or checking one's appearance, and enabling the lens 400 to function effectively during the opening and closing of the sun visor.

[0080] Based on this, the line contact between the lens 400 and the receiving groove 1013 can provide precise positioning for the lens 400, so that the lens 400 can remain in the predetermined position even when affected by external forces such as vibration and bumps during vehicle operation, and will not easily shift in the left, right or front and back directions. This effectively avoids the situation where the position changes will affect the use effect or collide with other components, ensuring the stability of the lens 400 installation and ensuring that it is always in a normal working state.

[0081] In some embodiments, see Figure 1 and combined Figure 3 The sun visor assembly in this application also includes a micro switch 500, which is disposed in the accommodating cavity. When the movable cover 200 opens at least part of the opening 102, the movable cover 200 is used to contact the micro switch 500. The micro switch 500 is a silent switch.

[0082] On this basis, the micro switch 500 can be configured to provide more functions for the sun visor.

[0083] For example, when the movable cover 200 is opened, the micro switch 500 is triggered, which can be linked with other electronic systems of the vehicle, such as automatically turning on the lighting system on the sun visor to provide better lighting conditions for the lens 400; or interacting with the vehicle's infotainment system to automatically play specific music or display specific information when the sun visor is opened according to the user's preset, thereby increasing the functionality and intelligence of the sun visor and improving the user's experience with the sun visor.

[0084] On the other hand, the micro switch 500 is a silent switch, so when the movable cover 200 is opened or closed, no additional noise is generated when the micro switch 500 is triggered by contact, thus improving the comfort experience inside the car.

[0085] In some embodiments, see Figure 1 and combined Figure 4 The sunshade body 100 in this application is also provided with an energy-absorbing component 600.

[0086] For example, an energy-absorbing element 600 is provided at or near the end of the sliding cover and on the surface of the corresponding limiting block.

[0087] When the sliding cover reaches its limit travel, the part where the two parts come into direct contact is the source of the impact force. Setting up an energy-absorbing component 600 at this point can directly absorb the impact energy and reduce the energy transfer to other parts, thus reducing abnormal noise.

[0088] In some embodiments, the micro switch 500 of this application is provided with an energy-absorbing element 600 to ensure the silent effect of the micro switch 500 when it is engaged with the movable cover 200.

[0089] For example, the energy-absorbing element 600 can be made of rubber. The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions within the technical scope disclosed in this application should be covered within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
