[0058] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

[0059] In addition, the present application may repeat reference numerals and / or reference letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or arrangements discussed. In addition, the present application provides examples of various specific processes and materials, but those of ordinary skill in the art can be aware of the application of other processes and / or the use of other materials.

[0060] The present application will be described below in conjunction with the accompanying drawings and with reference to specific embodiments:

[0061] On the door bodies of some electrical appliances such as refrigerators, a concave handle groove is usually provided as a handle structure to facilitate the fingers to reach into the handle groove to pull the door body open. In order to meet the requirements of the flatness and aesthetics of the door body, a shielding member such as a movable cover plate with a reset ability is mostly arranged in the handle groove area of the door body to form an openable concealed handle; when the handle groove needs to be operated, the shielding member is pushed to move to expose the handle groove for the fingers to reach into; after the fingers are withdrawn, the shielding member automatically resets to shield the handle groove.

[0062] However, during use, due to the high timeliness of the reset action of the shielding member, the phenomenon of the shielding member pinching the hand is likely to occur, making the operation of the door body inconvenient and there is a certain safety risk.

[0063] Therefore, the embodiments of the present application provide a handle assembly, a door body and an electrical appliance, aiming to at least solve to a certain extent the technical problem that the shielding member of the concealed handle on the door body of the electrical appliance is easy to pinch the hand, and improve the convenience and safety of using the concealed handle.

[0064] Figure 1 The structural explosion diagram of the handle assembly in the embodiment of the present application is shown; Figure 2 It shows Figure 1 The structural schematic diagram of the initial state of the shielding member in the handle assembly in Figure 3 It shows Figure 2 The three-dimensional structural schematic diagram of the initial state of the moving assembly and the damping mechanism in the handle assembly in Figure 4 It shows Figure 2 The top view of the initial state of the moving mechanism and the damping mechanism in the handle assembly in

[0065] See Figure 1 、 Figure 2 、 Figure 3And Figure 4 In some embodiments, the reset speed of the shielding member can be delayed through the structural design of the handle assembly, so as to leave more time for the operator to withdraw the finger, and to reduce the risk of pinching the finger by the shielding member to a certain extent. Specifically, the handle assembly may include: a mounting base 1, a shielding member 2, a damping mechanism 3, and a moving mechanism 4.

[0066] The mounting base 1 is the mounting foundation of the entire handle assembly, bearing the shielding member 2, the damping mechanism 3, and the moving mechanism 4, and mounting the handle assembly on the door body. A concave recess 15 is formed on the mounting base 1 for accommodating the finger, so as to pull the mounting base 1 through the finger, and then open the door body where the mounting base 1 is located.

[0067] The shielding member 2 is a movable shielding structure, which is movably connected to the mounting base 1 through the moving mechanism 4, so that the shielding member 2 can reciprocate relative to the mounting base 1 to shield or expose the recess 15. The shielding member 2 has a first position and a second position; wherein, the position where the shielding member 2 cooperates with the mounting group 1 to shield the recess 15 is the first position, and when the shielding member 2 moves to the first position, the recess 15 can be shielded; the position where the shielding member 2 exposes the recess 15 is the second position, and after the shielding member 2 moves away from the first position, the recess 15 is gradually exposed.

[0068] The damping mechanism 3 is connected between the mounting base 1 and the shielding member 2, and is used to apply a resistance to the shielding member 2 during the process of the shielding member 2 moving from the second position to the first position, so as to delay the moving speed of the shielding member 2 towards the first position and reduce the risk of pinching the finger caused by the too-fast reset of the shielding member 2. That is to say, the damping mechanism 3 is configured to generate damping during the process of the shielding member 2 moving from the second position to the first position to hinder and delay the moving speed of the shielding member 2 towards the first position, so as to leave enough time for operating the mounting base 1 and withdrawing the finger and reduce the risk of pinching the finger.

[0069] The moving mechanism 4 is connected between the mounting base 1 and the shielding member 2 and is the moving support structure of the shielding member 2. The shielding member 2 can move relative to the mounting base 1 along a set track under the guidance of the moving mechanism 4, so that the shielding member 2 can stably move to the first position, reliably shield the recess 15, and can stably and smoothly leave the first position to expose the recess 15. The moving mechanism 4 can also apply a reset force to the shielding member 2, drive the shielding member 2 to reset to the first position, and keep the shielding member 2 at the first position to ensure the shielding reliability and aesthetics of the shielding member 2.

[0070] When the handle assembly needs to be operated, the shielding member 2 can be pushed by an external force to move away from the first position along a set track under the guidance of the moving mechanism 4, and the recess 15 is gradually exposed. When the size of the exposed recess 15 can accommodate finger operation, the finger can be inserted into and hold the recess 15, and the mounting base 1 can be pushed and pulled.

[0071] After the handle assembly operation is completed, the finger will withdraw from the recess 15. Under the combined action of the reset force of the moving mechanism 4 and the damping of the damping mechanism 3, the shielding member 2 will slowly reset to the first position until it moves to the first position. During the normal operation of the handle assembly, the finger pushing the shielding member 2, extending into the recess 15 and pulling the mount 1 are smooth and coherent actions. Affected by the damping mechanism 3, the time for the shielding member 2 to move to the first position is greater than the time for the finger to pull the mount 1 and withdraw from the recess 15, thereby significantly reducing the risk of pinching the finger by the shielding member 2.

[0072] See Figure 2 , in some embodiments, the first position can be set to the position where the shielding member 2 completely shields the recess 15. Thus, when the handle assembly is installed on the door body, the shielding member 2 remains flush with the surface of the door body, ensuring the aesthetic appearance of the overall appearance.

[0073] The second position can be set to the position where the shielding member 2 at least partially exposes the recess 15. Thus, when the handle assembly is installed on the door body, the shielding member 2 can be pushed away from the first position by an external force until the finger naturally extends into the recess 15 and pushes and pulls the mount 1; then the finger is withdrawn, and the shielding member 2 slowly moves towards the first position until the shielding member 2 is flush with the surface of the door body.

[0074] The second position can be a position different from the first position, which is itself the position reached by the operator's finger pushing the shielding member 2; therefore, the specific position of the second position is affected by factors such as the pushing force of the pushing operation and the size of the operator's finger. Thus, the second position can be multiple positions with different distances from the first position.

[0075] In some embodiments, in order to balance the anti-pinching function and the convenience of operating the handle assembly, the damping mechanism 3 can be configured as a one-way damping mechanism; that is, only when the shielding member 2 moves from the second position to the first position, the damping mechanism 3 generates damping to delay the movement of the shielding member 3; during the process of the shielding member 2 moving from the first position to the second position, the damping mechanism 3 does not generate damping, so that the process of pushing the shielding member 2 by an external force to expose the recess 15 is smooth and unobstructed, facilitating the rapid exposure of the recess 15 and facilitating the operation of the handle assembly.

[0076] Figure 9 Shows Figure 1 the structural schematic diagram of the one-way damping gear in the handle assembly in Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 9, in some embodiments, in order to balance the one-way damping of the damping mechanism 3 and the smooth movement of the shielding member 2, the damping mechanism 3 may include: a one-way damping gear 31 and a rack 32; the one-way damping gear 31 and the rack 32 may be respectively arranged on the shielding member 2 and the mounting base 1, and the positions of the one-way damping gear 31 and the rack 32 may be exchanged according to the installation requirements.

[0077] When the one-way damping gear 31 is installed on the shielding member 2 and the rack 32 is arranged on the mounting base 1, the one-way damping gear 31 can move along with the shielding member 2 and move relative to the rack 32.

[0078] In order to enable the damping mechanism 3 to generate damping only during the movement of the shielding member 2 from the second position to the first position, by matching the trajectory of the one-way damping gear 31 with the shape and position of the rack 32, when the shielding member 2 moves towards the first position, the one-way damping gear 31 can smoothly and stably engage with the rack 32 to generate movement damping, delaying the relative movement between the shielding member 2 and the mounting base 1.

[0079] In some embodiments, in order to improve the smoothness of the cooperation between the one-way damping gear 31 and the rack 32 and reduce the risk of jamming, the length of the rack 32 can be configured such that the length of the rack 32 is greater than the length of the movement stroke of the one-way damping gear 31. Thus, during the reciprocating movement of the one-way damping gear 31 along with the shielding member 2, the one-way damping gear 31 is always engaged with the rack 32.

[0080] That is, when the shielding member 2 is in the first position, the one-way damping gear 31 is engaged with the rack 32, and when the shielding member 2 is pushed to the limit position, the one-way damping gear 31 is also engaged with the rack 32.

[0081] Figure 5 Shows Figure 1 a schematic structural view of the intermediate state of the shielding member in the handle assembly in Figure 6 Shows Figure 5 a schematic structural view of the intermediate state of the moving mechanism and the damping mechanism in the handle assembly in Figure 7 Shows Figure 1 a schematic structural view of the intermediate state of the shielding member in the handle assembly in Figure 8 Shows Figure 7 a schematic structural view of the intermediate state of the moving mechanism and the damping mechanism in the handle assembly in

[0082] See Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8, in some embodiments, considering that the one-way damping gear 31 and the rack 32 are respectively installed on the relatively movable shielding member 2 and the mounting base 1, in this case, it is difficult to perform the assembly operation by matching the meshing position of the one-way damping gear 31 and the rack 32. Therefore, the position of the rack 32 can be designed accordingly, and the rack 32 is arranged within the moving trajectory range of the one-way damping gear 31. When the shielding member 2 is in the first position, the one-way damping gear 31 does not mesh with the rack 32, and a certain distance is maintained between the one-way damping gear 31 and the rack 32. Thus, during assembly, it is not necessary to consider the meshing position between the gear part 311 and the rack 32, etc., which can reduce the assembly difficulty to a certain extent.

[0083] Only when the shielding member 2 moves away from the first position by a certain distance, the one-way damping gear 31 meshes with the rack 32; when the shielding member 2 moves towards the first position to a certain distance from the first position, the one-way damping gear 31 disengages from the rack 32, and the shielding member 2 quickly moves to the first position.

[0084] In some embodiments, in order to balance the assembly convenience and the anti-pinch reliability, the distance between the rack 32 and the one-way damping gear 31 can be reasonably set. That is, when the shielding member 2 is in the first position, the rack 32 does not mesh with the one-way damping gear 31, and the one-way damping gear 31 needs to move a certain distance following the shielding member 3 to be able to mesh with the rack 32, thereby leaving enough space for the assembly of the one-way damping gear 31 and fully ensuring the damping action time and reducing the risk of pinching hands.

[0085] Therefore, the meshing stroke of the one-way damping gear 31 and the rack 32 can be greater than or equal to 2 / 3 of the moving stroke of the gear part, that is, when the shielding member 2 is in the first position, the stroke length between the rack 32 and the one-way damping gear 31 is less than 1 / 3 of the moving trajectory stroke of the one-way damping gear 31.

[0086] In some embodiments, the one-way damping gear 31 may include a housing, a rotating shaft, a one-way bearing, a damping block, and a gear 311.

[0087] A sealed damping cavity is provided inside the housing, and the damping cavity is filled with damping fluid, and the housing can be connected to the shielding member 2; the rotating shaft is rotatably arranged on the housing, and the rotating shaft includes an inner shaft rod located in the damping cavity and an outer shaft rod located outside the housing; the one-way bearing is arranged on the inner shaft rod; the damping block is sleeved on the one-way bearing, and the damping block is located in the damping cavity; the gear is arranged on the outer shaft rod, and the gear is configured to mesh with the rack during the process of the shielding member moving towards the first position.

[0088] When the gear 311 meshes with the rack 32 and the gear 311 follows the shielding member 2 to leave the first position, the gear 311 and the rotating shaft rotate in the first direction in the one-way bearing, and the one-way bearing and the damping block do not rotate therewith, that is, the one-way damping gear 31 does not generate damping, so that the shielding member 2 can be quickly pushed by an external force to expose the recess 15.

[0089] When the gear 311 meshes with the rack 32 and the gear 311 follows the shielding member 2 to move towards the first position, the gear 311 drives the rotating shaft, the one-way bearing, and the damping block to rotate in the direction opposite to the first direction, thereby pushing the damping fluid to flow slowly, so that the one-way damping gear 31 generates damping, and thus the shielding member 2 slowly moves towards the first position.

[0090] In some embodiments, the damping fluid may be damping oil with a certain viscosity or a fluid of other materials.

[0091] In some embodiments, the damping mechanism connected to the gear 311 of the one-way damping gear 31 may also adopt a damping mechanism based on electromagnetic principles or a damping mechanism with a reed moving away.

[0092] In some embodiments, the one-way damping gear 31 may be disposed on the side of the shielding member 2 facing the recess 15, and the rack 32 may be disposed in the recess 15, so that the damping mechanism 3 can be integrally shielded in the space surrounded by the shielding member 2 and the recess 15, thereby preventing the damping mechanism 3 from being exposed outside to maintain the overall appearance neatness of the handle assembly.

[0093] See Figure 1 , in some embodiments, considering that the handle assembly is mostly disposed in the edge area of the door body, in order to smoothly connect the peripheral surface 52 and the main surface 51 of the door body 5, the mounting seat 1 may include: a first surface 12 and a second surface 13, the first surface 12 and the second surface 13 are connected, and the recess 15 may be disposed on the second surface 13, and the recess 15 penetrates the first surface 12, that is, the recess 15 may be recessed inward from the connection area of the first surface 12 and the second surface 13.

[0094] That is, in order to adapt to the connection positional relationship between the main surface 51 and the peripheral surface 52 of the door body, the mounting seat 1 is provided with the connected first surface 12 and second surface 13, and the recess 15 is correspondingly and matchingly disposed in the connection edge area of the main surface 51 and the peripheral surface 52 of the door body, so that when the handle assembly is mounted on the door body, the recess 15 also correspondingly appears at the edge of the door body to match the conventional usage habits.

[0095] In some embodiments, in order to match and shield the recess 15 located in the connection edge area of the first surface 12 and the second surface 13, the shielding member 2 may respectively shield the recessed areas located in the areas of the first surface 12 and the second surface 13.

[0096] The shielding member 2 may include a connected first plate body 21 and a second plate body 22, and the joining posture of the first plate body 21 and the second plate body 22 may be set with reference to the joining posture of the first surface 12 and the second surface 13. When the shielding member 2 is in the first position, the shielding member 2 shields the concave portion 15, and the first plate body 21 is flush with the first surface 12, and the second plate body 22 is flush with the second surface 13, so that the shielding member 2 can be integrally matched and flat with the mounting base 1 to completely shield the concave portion 15.

[0097] In some embodiments, considering that the main surface 51 of the door body and the peripheral surface 52 are substantially at a right angle, the included angle between the first surface 12 and the second surface 13 may also be set to a right angle, and the first plate body 21 and the second plate body 22 may also be set to a state perpendicular to each other.

[0098] The position matching of the shielding member 2 and the mounting base 1 can also be set so that the shielding member 2 can take into account both the movement and the shielding effect. For example, when the shielding member 2 is in the first position, the first plate body 21 may be configured to be flush with the first surface 12 to shield the concave portion 15 along the first surface 12; the second plate body 22 is configured to be slightly higher than the second surface 13 to shield the concave portion 15 from the outside of the second surface 13, so as to take into account both the shielding function and the smooth movement.

[0099] In some embodiments, the one-way damping gear 31 may be disposed on the side plate surface of the second plate body 22 facing the second surface 13, and the rack 32 is correspondingly disposed on the second surface 13.

[0100] In some embodiments, in order to reduce the fitting gap between the second plate surface 22 and the second surface 13 and reduce the overall installation height, a sunk groove 131 may be provided on the second surface 13, the rack 32 is disposed in the sunk groove 131, and the meshing movement of the gear 311 and the rack 32 may sink in the sunk groove 131.

[0101] In some embodiments, the depth and width of the sunk groove 131 may be increased, so that the one-way damping gear 31 can be accommodated, and the fitting gap between the second plate surface 22 and the second surface 13 can be further reduced.

[0102] In some embodiments, in order to facilitate pushing and pulling the mounting base, a handle groove 11 may be provided at the bottom of the concave portion 15 to accommodate the fingers of the operator. The mounting base 1 can be stably held by inverting the fingers in the handle groove 11, and the mounting base 1 can be stably pushed and pulled.

[0103] Figure 10 shows Figure 1 the structural schematic diagram of the rotating shaft in the handle assembly in Figure 11 shows Figure 1 the structural schematic diagram of the reset member in the handle assembly in

[0104] See Figures 1 to 11, in some embodiments, in order to prevent the moving mechanism 4 from being exposed outside the mounting base 1 and affecting the neatness, the moving mechanism 4 can be arranged in the recess 15, and the recess 15 is blocked by the cooperation of the shielding member 2 and the mounting base 1.

[0105] In some embodiments, the moving mode of the shielding member 2 can be configured in a deflection mode, that is, the shielding member 2 is pivotally mounted on the mounting base 1 and blocks the recess 15 in the first position. The moving mechanism 4 can be respectively connected to the shielding member 2 and the mounting base 1. When an external force pushes the shielding member 2 to move, the moving mechanism 4 guides the shielding member 2 to deflect relative to the mounting base 1 and applies a restoring force to the shielding member 2.

[0106] The moving mechanism 4 can include a rotating shaft 41 and a restoring member 42; the rotating shaft 41 is connected between the shielding member 2 and the mounting base 1. When the shielding member 2 is pushed by an external force, the shielding member 2 deflects and moves along a set track under the guidance of the rotating shaft 41; the restoring member 42 is connected between the shielding member 2 and the mounting base 1, and applies a restoring force to the shielding member 2 based on the mounting base 1 to drive the shielding member 2 to move to the first position.

[0107] In some embodiments, two sets of rotating shafts 41 can be provided, and the rotation modes of the two sets of rotating shafts 41 are configured to be the same, and are respectively connected to the mounting base 1 and the shielding member 2 to form a double-rotating-shaft deflection structure.

[0108] The rotating shaft 41 can include: a first rotating shaft 411, a connecting portion 412, and a second rotating shaft 413; the first rotating shaft 411 and the second rotating shaft 413 are connected by the connecting portion 412. The first rotating shaft 411 is rotatably arranged on the mounting base 1, and the second rotating shaft 413 is pivotally connected to the shielding member 2; when the shielding member 2 is pushed by an external force, the shielding member 2 rotates relative to the first rotating shaft 411, and the second rotating shaft 413 rotates relative to the mounting base 1.

[0109] Since there are two sets of rotating shafts 41 and the rotation modes are the same, the shielding member 2 is restricted by the two sets of rotating shafts 41 during the deflection process. When the shielding member 2 deflects relative to the mounting base 1, the deflection steps of each region of the shielding member 2 are consistent, that is, the shielding member 2 maintains its spatial attitude and translates as a whole, and the shielding member 2 is pulled by the rotating shaft 41 and deflects relative to the mounting base 1 as a whole, which can limit the spatial flipping amplitude of the shielding member 2, thereby reducing the interference risk with the surrounding structures.

[0110] In some embodiments, in order to further limit the risk of deflection of the shielding member 2, the first rotating shaft 411 and the second rotating shaft 413 can be set to be parallel, and the distance between the two first rotating shafts 411 connected to the shielding member 2 is equal to the distance between the two second rotating shafts 413 connected to the mounting base 1, so that the connecting lines of the two sets of rotating shafts 41 with the rotation points of the shielding member 2 and the mounting base 1 are substantially parallelograms. During the deflection process of the shielding member 2 relative to the mounting base 1, the form and amplitude of the constraint of the shielding member 2 by the rotating shaft 41 are the same, that is, the spatial attitude is maintained stable, and the amplitude of each region of the shielding member 2 approaching or moving away from the mounting base 1 is the same.

[0111] See Figure 6 and Figure 11 , in some embodiments, the reset member 42 may include a torsion spring 421. The torsion spring 421 can be formed by curling a steel wire into a cylinder, and may include a cylindrical main body 421a, a first extension portion 421b, and a second extension portion 421c. The main body 421a is sleeved on the first rotating shaft 411, the first extension portion 421b is connected to the shielding member 2, and the second extension portion 421c is connected to the mounting base 1.

[0112] When the distance between the shielding member 2 and the mounting base 1 changes, the torsion spring 421 will be compressed or stretched, so that the elastic deformation amplitude of the torsion spring 421 changes, generating a certain degree of elastic reset force, which is applied to the shielding member 2 to drive the shielding member 2 to reset to the first position.

[0113] See Figure 3 , in some embodiments, the reset member 42 may include a torsion spring 421. The torsion spring 421 can be formed by curling a steel wire into a cylinder, and may include a cylindrical main body 421a, a first extension portion 421b, and a second extension portion 421c. And considering that the shielding member 2 is an external structural member that is exposed and visible, in order to avoid the force of the torsion spring 421 causing changes in the shape and appearance of the shielding member 2, affecting the aesthetics and functions, the main body 421a of the torsion spring 421 can be sleeved on the first rotating shaft 411, and the first extension portion 421b and the second extension portion 421c are respectively connected to the connecting portion 412 and the mounting base 1, that is, to avoid the torsion spring 421 being directly connected to the shielding member 2 and reduce the influence of the direct pressure of the torsion spring 421.

[0114] When the distance between the shielding member 2 and the mounting base 1 changes, synchronously changing the distance between the connecting portion 412 and the mounting base 1 will compress or stretch the torsion spring 421, so that the elastic deformation amplitude of the torsion spring 421 changes, generating a certain degree of elastic reset force, which is applied to the connecting portion 412 to indirectly drive the shielding member 2 to reset to the first position.

[0115] In some embodiments, in order to reduce the complexity of the structure and operation of the handle assembly, the moving stroke of the shielding member 2 should not be too long. For this purpose, a stop boss 412a can be provided on the connecting portion 412, and a matching limit groove 14 can be provided on the mounting base 1. The stop boss 412a can be slidably embedded in the limit groove 14, and the moving stroke of the stop boss 412a can be limited through the specification design of the limit groove 14, so as to limit the stroke of the connecting portion 412, the second rotating shaft 413 and the shielding member 2, and prevent the shielding member 2 from moving excessively; to a certain extent, it can also strengthen the position-holding ability of the shielding member 2 and maintain the appearance flatness and aesthetics of the matching state between the shielding member 2 and the mounting base 1.

[0116] See Figure 6 and Figure 8 , in some embodiments, a pivot sleeve 211 can be provided on the first plate body 21 for sleeving and fixing the second rotating shaft 413; correspondingly, the first extension portion 421b of the torsion spring 421 can be connected to the first plate body 21.

[0117] In some embodiments, a plurality of pivot sleeves 211 can be provided, and the plurality of pivot sleeves 211 are coaxially arranged and protrude from the plate surface of the first plate body 21; correspondingly, the second rotating shaft 413 can also be provided with a corresponding number of short shafts, which are pivotally connected in the plurality of pivot sleeves 211.

[0118] See Figure 1 , Figure 3 , Figure 4 and Figure 12 , in some embodiments, one end of the first rotating shaft 411 can be rotatably arranged at the bottom of the recessed portion 15, and the other end is pivotally connected to the cover plate 16 on the second surface 13; wherein, the cover plate 16 can be pressed on the second surface 13 through fasteners such as screws 161.

[0119] In some embodiments, the moving form of the shielding member 2 can be set as linear movement, and a linear guiding mechanism can be configured between the shielding member 2 and the mounting base 1 to constrain the linear movement of the shielding member 2.

[0120] In some embodiments, a door body is further provided, which includes a door main body 5 and the above-mentioned handle assembly, and the mounting base 1 can be installed on the door main body 5.

[0121] The first surface 12 of the mounting base 1 can be smoothly connected to the main surface 51 of the door main body 5, and the second surface 13 can be smoothly connected to the peripheral surface 52 of the door main body 5.

[0122] In some embodiments, an electrical device is further provided, which includes a door body. The electrical device can be a device with a door body such as a refrigerator, a freezer, a dishwasher, etc.

[0123] The embodiments of the present application at least have the following beneficial effects:

[0124] The handle assembly provided by the embodiment of the present application includes a mounting base, a shielding member, a damping mechanism, and a moving mechanism. A recess is provided on the mounting base for accommodating fingers to push and pull the mounting base, thereby realizing the operation of opening and closing the door. The shielding member is a shielding structure that matches and shields the handle groove. It is movably mounted on the mounting base through the moving mechanism. The recess can be shielded by moving the shielding member to the first position, and the recess is exposed when the shielding member is moved out of the first position. The moving mechanism can guide the shielding member to move along a set track, stably and reliably realizing the exposure and shielding operations of the recess. Moreover, the moving mechanism can drive the shielding member to reset to the first position, so that the shielding member can be pushed relative to the mounting base by an external force to expose the handle groove, and when the external force is removed, the moving mechanism drives the shielding member to reset and shield the recess to keep the appearance of the mounting base flat and beautiful. On the other hand, the damping mechanism is connected between the mounting base and the shielding member, generating damping during the process of the shielding member moving from the second position to the first position, thereby being able to delay the reset moving speed of the shielding member to the first position, increasing the holding time of the shielding member exposing the recess, facilitating the extraction of the fingers in the recess, thereby reducing the risk of pinching hands and improving the safety and smoothness of the door opening and closing operation.
