Optionally, an included angle is formed between the straight line where the length of the guide rail groove 3 is located and the straight line where the length direction of the slide rail is located;
further, the cover door 2 is slidably disposed on the top cabinet opening 11 through a slide rail as shown in fig. 1, at this time, the cover door 2 is completely closed, the top cabinet opening 11 is covered, at this time, the cover door 2 is completely opened, the top cabinet opening 11 is exposed, and the cover door 2 is accommodated in the guide rail groove 3 as shown in fig. 2. That is, taking the case that the cover door 2 slides up and down, the guide rail groove 3 is provided at the top end or bottom end of the top cabinet 1.
Alternatively, referring to fig. 3, the door 2 includes a plurality of door units 4, the length direction of the door units 4 being perpendicular to the length direction of the slide rail, and the plurality of door units 4 being hinge-connected. Specifically, as shown in fig. 1, the length direction of the single door unit 4 is perpendicular to the length direction of the slide rails, and the length of the door unit 4 is greater than the distance between the two slide rails, so that the door unit 4 can slide on the slide rails; in the process of the cover door 2 from the closed state of fig. 1 to the open state of fig. 2, the sliding path of the cover door 2 enters the guide rail groove 3 from the sliding rail, a corner is formed at the joint of the sliding rail and the guide rail groove 3, and the hinged cover door unit 4 rotates relatively at the corner, so that the turning function of the cover door 2 is realized, and finally the cover door enters the guide rail groove 3. Further, the door 2 is configured such that at least part of the door unit 4 is located in the rail groove 3 when the top cabinet opening 11 is opened.
The embodiment of the application provides a sliding cover door, wherein the cover door 2 is arranged on a top cabinet opening 11 in a sliding way through a sliding rail, and an opening and closing function is realized through sliding in the sliding rail, and the sliding cover door is stored in a guide rail groove 3 when being opened, is hidden and invisible as a whole, does not occupy space and is attractive;

In some alternative embodiments, as shown in fig. 5, 7 and 8, a turning point 6 is formed between the guide rail groove 3 and the slide rail, and the included angle α between the guide rail groove 3 and the slide rail is smaller than 90 °;
further, as can be seen from the left side view of the cover door 2 in connection with fig. 3, two adjacent cover door units 4 are connected by a buckling structure 7 towards the side of the top cabinet opening 11, and the cover door 2 is configured such that the cover door units 4 located at both sides of the turning point 6 are rotated around the buckling structure 7 when the cover door 2 enters the guide rail groove 3.
As shown in fig. 8, the cover door 2 is provided with an up-down sliding guide rail groove 3 at the top end or bottom end of the top cabinet 1; opening the cover door 2, wherein part of the cover door 2 enters the guide rail groove 3, and when the cover door passes through the turning point 6, the cover door unit 4 hinged through the buckling structure 7 rotates relatively, so that the flow of the cover door unit entering the guide rail groove 3 from the sliding rail is realized; at this time, the included angle α between the guide rail groove 3 and the slide rail is smaller than 90 ° and can assist the door unit 4 entering the guide rail groove 3, that is, the door unit 4 entering the guide rail groove 3 will form a pulling force on the door unit 4 still in the slide rail, so as to slow down the falling of the door unit 4 in the slide rail caused by gravity.
Optionally, when the cover door 2 slides left and right, the guide rail groove 3 is arranged on the side wall of the top cabinet 1, and the angle of the included angle alpha between the guide rail groove 3 and the sliding rail is based on the arrangement of the top cabinet 1.
In some alternative embodiments, as shown in fig. 3-4, the crimping structure 7 includes a snap-in portion 71 and a rotating portion 72, wherein the rotating portion 72 of one door unit 4 is retained in the snap-in portion 71 of an adjacent door unit 4 of the door unit 4.
As shown in fig. 4, two cover door units 4 are respectively provided as a first cover door unit 41 and a second cover door unit 42, wherein the first cover door unit 41 and the second cover door unit 42 are respectively provided with a snap-in portion 71 and a rotation portion 72, and wherein the snap-in portion 71 of the first cover door unit 41 is connected with the rotation portion 72 of the second cover door unit 42; in fig. 4, the first door unit 41 and the second door unit 42 rotate relatively, wherein the rotated second door unit 42 is shown in the schematic diagram of fig. 4.
Specifically, the engagement portion 71 and the rotation portion 72 are shaft-hole engagement structures, and when the first door unit 41 and the second door unit 42 rotate relatively, they rotate around the shaft center, and when the door 2 moves to the turning point 6, the adjacent door units 4 rotate relatively, turn, and enter the guide groove 3.
Alternatively, as shown in fig. 3, the side of the cover door 2 away from the top cabinet 1 is a cover door outer surface 45, and the side of the cover door 2 facing the top cabinet 1 is a cover door inner surface 46, wherein the buckling structure 7 is disposed on the cover door inner surface 46 of the cover door 2, and the abutment structure 8 is disposed on the cover door outer surface 45.
As shown in fig. 4, the abutting structure 8 includes a convex section 81 and a concave section 82, and is configured such that, when the door 2 is slidably disposed in the slide rail, the convex section 81 of one door unit 4 abuts in the concave section 82 of the adjacent door unit 4, i.e., the positional relationship of the door units 4 as shown in fig. 3.
Further, the abutting structure 8 is disposed in the opposite direction of the buckling structure 7, that is, the two adjacent cover door units 4 can only rotate to the side where the buckling structure 7 is located, and when the cover door 2 is disposed in the sliding rail, the abutting structure 8 supports the adjacent cover door units 4, so that the adjacent cover door units 4 cannot deform.
In some alternative embodiments, referring to fig. 1 and 2, the top cabinet 1 includes a top cabinet side slot 12, and slide rails are disposed on the left and right sides of the top cabinet opening 11, that is, in the top cabinet side slot 12, where the movement direction of the cover door 2 when opening and closing is up and down, and the guide rail slot 3 in this embodiment is located at the top end or the bottom end of the top cabinet 1.
In this embodiment, the guide rail groove 3 is shown in fig. 5 and is disposed at the top end of the top cabinet 1, that is, the cover door 2 slides upwards when opened, a turning point 6 is disposed between the guide rail groove 3 and the sliding rail, the turning point 6 is a smooth curve, and an included angle α between the guide rail groove 3 and the sliding rail is smaller than 90 °.
When the cover door 2 is closed as shown in fig. 1, the bottom end of the cover door 2 is connected with the top cabinet bottom plate 13 at the bottom end of the top cabinet 1, the top cabinet bottom plate 13 has upward supporting force on the cover door 2, and the cover door 2 is kept in the closed state as shown in fig. 1 under the condition of no external force influence;
when the door 2 needs to be opened, an upward pushing force is applied to the door 2 and is larger than the dead weight of the door 2, and at this time, the door 2 has a tendency to move upward (toward the track groove 3), and as the door 2 is opened, the door units 4 in the slide rails are less and less, and the top cabinet opening 11 is exposed, i.e., the door 2 is opened.
Further, as shown in fig. 7 and 8, the wear-resistant adhesive tape 5 is arranged in the slide rail, and the friction force of the wear-resistant adhesive tape 5 on the door 2 is not less than the dead weight of the door 2. Specifically, the wear-resistant adhesive tape 5 can extrude the cover door 2, so that the friction resistance between the cover door 2 and the sliding rail is increased, the trend of the cover door 2 sliding down due to dead weight is prevented, meanwhile, the gap between the cover door 2 and the sliding rail can be eliminated, abnormal sound generated by shaking in the running process of a vehicle is eliminated, and finally, the cover door can be stopped at will (hovering at a certain position of the sliding rail) and stopped at maximum (the cover door 2 is completely closed) in the opening process of the cover door.
It should be noted that, referring to fig. 7 and 8, the abrasion-resistant adhesive tape 5 is extruded under the pressure of the cover door 2, and the dotted line intersecting with the cover door 2 in the figure is the thickness of the abrasion-resistant adhesive tape in the free state; after the wear-resistant adhesive tape 5 is extruded and deformed, reverse extrusion force can be generated on the cover door 2 due to self rebound capability, and when the cover door 2 slides or has a sliding trend, dynamic friction force or static friction force is generated on the cover door 2, so that the effect of counteracting the self weight of the cover door 2 is achieved. Further, the pressure of the wear-resistant adhesive tape 5 on the cover door 2 is related to the mechanical performance of rubber compression, and the corresponding extrusion force can be obtained by repeatedly adjusting the compression amount of different rubber strips, so that the friction force of the wear-resistant adhesive tape 5 on the cover door 2 is obtained.
Specifically, the top cabinet 1 includes a top cabinet bottom plate 13, and the setting positions of the wear-resistant adhesive tape 5 are: one end of the wear-resistant adhesive tape 5 is connected with the top cabinet bottom plate 13, and the length of the wear-resistant adhesive tape is equal to that of the cover door 2, and the whole arrangement mode is shown in fig. 7, and optionally, the wear-resistant adhesive tape 5 is adhered in a sliding rail. When the cover door 2 is closed, the bottom end of the cover door 2 is connected with the top cabinet bottom plate 13;
further, the friction force of the wear-resistant adhesive tape 5 to the cover door 2 is equal to the self weight of the cover door 2. As can be seen by combining fig. 7 and 8, the sliding rail has an arc-shaped turning point 6 between the guide rail grooves 3, and before the cover door 2 moves upwards by applying an external force, the cover door unit 4 closest to the guide rail grooves 3 still has a distance from entering the guide rail grooves 3, so that the dead weight G of the cover door 2 in the sliding rail will not change before the cover door unit 4 closest to the guide rail grooves 3 enters the guide rail grooves 3, and at this time, the friction force f of the cover door 2 is equal to the dead weight of the cover door 2, thereby realizing hovering of the cover door 2.
Because the wear-resistant adhesive tape 5 has extrusion force to the cover door 2, when the cover door 2 is driven by upward external force to start moving, the cover door 2 is subjected to friction force f of the wear-resistant adhesive tape 5, and the direction of the friction force f is opposite to the gravity G direction of the cover door 2, so that balance is realized.
When the abrasion-resistant adhesive tape 5 is extruded, the extrusion amount is generated at first, the corresponding extrusion force is obtained by repeatedly adjusting the compression amount of the abrasion-resistant adhesive tape 5, and when the cover door 2 slides up and down, in order to keep the cover door 2 hovering at a certain position, the friction force f born by the cover door 2 is required to be not less than the dead weight G of the cover door 2; by applying the external force F, the mechanical balance of the self weight G of the cover door 2 and the friction force F of the wear-resistant adhesive tape 5 to the cover door 2 is broken, so that the opening and closing functions are realized. The theoretical formula is: f+f is more than G, so that the cover door is opened; F+G > F, realizing the closing of the cover door.
Further, after the door units 4 enter the guide rail groove 3, the number of the door units 4 which are positioned in the slide rail and are in contact with the wear-resistant adhesive tape 5 is reduced, and the hovering can still be realized because the friction force and the friction coefficient are related to the applied pressure (namely the extrusion force of the wear-resistant adhesive tape 5 to the door units 4 in the embodiment), and the friction force borne by the door units 4 is unchanged at the moment, so that the gravity is reduced.
In some alternative embodiments, when the cover door 2 is opened, the sum of the traction force of the cover door unit 4 located in the rail groove 3 against the cover door unit 4 located in the rail and the friction force of the cover door unit 4 located in the rail by the abrasion resistant rubber strip 5 is greater than the dead weight of the cover door unit 4 located in the rail.
At this time, as shown in fig. 8, the door unit 4 passing through the turning point 6, which is separated from the abrasion-resistant adhesive tape 5, enters the guide rail groove 3, and is formed into a third door unit 43, and the third door unit 43 is decomposed into forces F in two directions by gravity 1 (parallel to the rail groove 3 direction, since α is smaller than 90 °, the third door unit 43 has a pulling force on the door unit 4 in the rail) and F 2 (pressure of the third door unit 4 against the guide rail groove 3 perpendicular to the guide rail groove 3) assuming that the door 2 includes n door units 4, and that the weight of the door units 4 is equal, the mechanical relationship is:
F 1 ＝G 1 *cosα，F 2 ＝G 1 *sinα，f 1 ＝μ*F 2 (wherein G 1 For the weight of the door unit 4/the third door unit 43, α is the angle between the slide rail and the guide rail groove 3, μ is the friction coefficient of the guide rail groove 3, f 1 Friction force for the guide rail groove 3 against the third cover door unit 43);
assuming that the cover door 2 includes n cover door units 4, and that the weights of the cover door units 4 are equal, a mechanical formula for realizing hovering of the cover door 2 is:
F 1 +f 1 +(n-2)*f＞(n-1)*G 1 (wherein G 1 The gravity of the single cover door unit 4, and f is the sliding friction force between all the cover door units 4 and the wear-resistant adhesive tape 5);
the reason (n-2) is that when the door unit 4 rotates, the door unit 4 is at the turning point 6, that is, as shown in fig. 8, the door unit 4 connected to the third door unit 43 is referred to as the fourth door unit 44, and the fourth door unit 44 is not in contact with the abrasion-resistant rubber strip 5 nor enters the guide rail groove 3, so the number of the door units 4 in contact with the abrasion-resistant rubber strip 5 is n-2;
meanwhile, as shown in fig. 8, before the fourth door unit 44 enters the guide rail groove 3, the third door unit 43 is still pulled by the gravity of the remaining door units 4, so the weight of the third door unit 43 pulled is (n-1) G 1 。
Wherein the gravity G of the cover door unit 4/the third cover door unit 43 1 The number n of door units 4, the friction force f applied to the door 2 and the friction coefficient mu can be obtained by measurement, so that the included angle alpha between the guide rail groove 3 and the sliding rail, namely the maximum allowable included angle, can be obtained.
In some alternative embodiments, see FIG. 7, the length L of the door 2 1 Greater than the length L of the guide rail groove 3 added to the turning point 6 2 . This prevents the door 2 from sliding into the guide groove 3 and being unable to be pulled out.
In some alternative embodiments, referring to fig. 7, the top cabinet 1 comprises a top cabinet hopper 14, and the side of the turning point 6 away from the top cabinet hopper 14 is provided with an opening; the length of the guide rail groove 3 is L 3 Length L of door 2 1 Length L greater than the guide rail groove 3 3 .
