Description

Technical Field

[0001] The utility model relates to the technical field of translation guide devices, in particular to a bidirectional translation positioning mechanism, an automobile armrest box structure, a sliding door structure and a sliding window structure. Background Art

[0002] In the prior art, structures such as sliding doors and windows, and car armrest boxes all have a fixed end that remains in a fixed position and a movable end that can move horizontally relative to the fixed end. A guide rail is provided between the movable end and the fixed end to achieve guidance during horizontal movement, and the friction force on the movable end during movement is reduced by rollers, balls, and other similar mechanisms, so that the movable end can be pushed more easily.

[0003] Although the above-mentioned guide rail design can make the translation of the movable end smooth, due to the lack of positioning design during the translation process, if the force used to push the movable end is slightly greater, the movable end may be pushed to the bottom, causing the movable end to directly hit the frame of the fixed end, causing noise or even damage, or the movable end may be directly removed from the guide rail and fall off, resulting in low safety and poor user experience. Utility Model Content

[0004] The purpose of the utility model is to provide a two-way translation positioning mechanism, a car armrest box structure, a sliding door structure and a sliding window structure, which can realize two-way translation of the movable end and have a controllable mobile positioning function during the translation process.

[0005] In order to achieve the above object, one of the solutions of the utility model is:

[0006] The cam is an elastic member formed between a tooth and a support frame, and the cam is provided with a toothed structure which is cooperatively connected with the toothed structure and is convenient to use and can be used for supporting the toothed structure in a variety of ways.

[0007] A first mounting groove is provided on the upper surface of the fixed end, and the slide rail is installed in the first mounting groove; a second mounting groove is provided on the lower surface of the movable end, and the slide seat is installed in the second mounting groove, and both ends of the second mounting groove extend toward both ends of the movable end to form movable grooves, and the slide rail is movably engaged in the movable groove as the movable end and the fixed end move relative to each other.

[0008] A slide seat installation groove is arranged at one end of the slide seat, and one end of the pawl is rotatably fitted in the slide seat installation groove through a rotating shaft.

[0009] Preferably, the elastic member is a torsion spring, which is sleeved on the rotating shaft, and whose two ends respectively abut against the sliding seat and the pawl; a step for the end of the torsion spring to abut is provided in the sliding seat installation groove.

[0010] Preferably, a blocking rod is arranged in the slide seat installation groove, and a blocking arm is arranged at one end of the pawl, and the pawl is movably abutted against the blocking rod when being pushed by the operating rod.

[0011] The upper edges of both side walls of the groove are recessed to form slide rail grooves, which match the shape of the operating rod. The operating rod slides in the slide rail groove without contacting the one-way ratchet. The slide seat is slidably sleeved on the slide rail and prevents the operating rod from leaving the slide rail groove.

[0012] Preferably, a protrusion is formed on the surface of the operating rod, and a retaining rib opposite to the protrusion is provided in the sliding seat; and an inclined surface is provided at the end of the operating rod that movably abuts against the pawl.

[0013] The second solution of the utility model is:

[0014] A car armrest box structure comprises the bidirectional translation positioning mechanism, wherein the fixed end is a box body, the movable end is a box cover, the box body is provided with a storage slot; and two groups of translation positioning components are respectively arranged on both sides of the storage slot.

[0020] The utility model provides a translation positioning assembly between the fixed end and the movable end, and the translation positioning assembly is composed of a slide rail with a one-way ratchet and a slide seat with a pawl installed. When the slide seat with the pawl installed moves along the inclined surface direction of the one-way ratchet, it will not be restricted by the one-way ratchet. On the contrary, the pawl will be pressed against the cross section of the one-way ratchet and restricted from moving. Since the two sets of translation positioning assemblies are centrally symmetrical, that is, the one-way ratchets of the two sets of slide rails are in opposite directions, the movable end will be restricted when it is translated left and right relative to the fixed end. At this time, when it is necessary to move the movable end toward one end of the fixed end (such as the right side), it is only necessary to operate the end The operating rod on the upper part (such as the right end) makes it slide between the slide seat and the slide rail and push the pawl on the corresponding side to disengage from the corresponding one-way ratchet, so that the one-way ratchet on this side no longer restricts the movement in this direction, and the pawl on the other side will not restrict the movement in this direction because it follows the direction of its corresponding one-way ratchet. At the same time, the two sets of slide seats and slide rails can cooperate to play an auxiliary guiding role in the movement of the active end to achieve smooth movement of the active end, so that the active end can be moved conveniently and quickly. After the user releases the operating rod, the pawl is reset under the action of the elastic member and returns to the state of restricting movement, thereby realizing the positioning function after the active end is translated and the positioning function is controllable.

[0032] In order to further explain the technical solution of the present utility model, the present utility model is described in detail below through specific embodiments.

[0033] refer to Figures 1 to 3 The first embodiment of the utility model is shown.

[0034] The first embodiment discloses a bidirectional translation positioning mechanism, including a fixed end 1, a movable end 2, and two sets of centrally symmetrical translation positioning components 3 arranged between the fixed end 1 and the movable end 2; (the fixed end 1 and the movable end 2 do not show specific devices or structures in the figure, and may be devices or structures corresponding to the second, third, and fourth embodiments described below, or other corresponding structures capable of installing this embodiment);

[0035] The translation positioning assembly 3 includes a slide seat 31, a slide rail 32, a pawl 33, an elastic member 34 and an operating rod 35;

[0036] The slide seat 31 and the slide rail 32 are slidably matched, and both are installed on the opposite surfaces of the fixed end 1 and the movable end 2 respectively;

[0037] The slide rail 32 is recessed to form a groove 321, and a plurality of one-way ratchet teeth 322 are arranged in the groove 321;

[0038] One end of the pawl 33 is pivotally connected to the slide seat 31, and the other end thereof is movably connected to the one-way ratchet 322;

[0039] The elastic member 34 is disposed between the pawl 33 and the slide seat 31, and is used to drive the pawl 33 to rotate so that the other end of the pawl 33 is reset toward the slide rail 32, so that the other end of the pawl 33 can be kept against the one-way ratchet tooth 322 under normal conditions;

[0040] The operating rod 35 is slidably fitted between the slide seat 31 and the slide rail 32, and one end of the operating rod 35 movably abuts against the pawl 33 to drive the other end of the pawl 33 to disengage the one-way ratchet 322, and the other end of the operating rod 35 is located on the surface of the fixed end 1 or the movable end 2 for easy operation.

[0041] Through the above scheme, the utility model sets a translation positioning assembly 3 between the fixed end 1 and the movable end 2, and the translation positioning assembly 3 is composed of a slide rail 32 with a one-way ratchet 322 and a slide seat 31 equipped with a pawl 33. When the slide seat 31 equipped with the pawl 33 moves along the inclined direction of the one-way ratchet 322, it will not be restricted by the one-way ratchet 322. On the contrary, the pawl 33 will be pressed against the cross section of the one-way ratchet 322 and restricted from moving. Since the two groups of translation positioning assemblies 3 are centrally symmetrical, that is, the one-way ratchet 322 of the two groups of slide rails 32 are in opposite directions, the movable end 2 will be restricted when it is translated left and right relative to the fixed end 1. At this time, when it is necessary to move the movable end 2 toward one end of the fixed end 1 (such as the right side), only The operating rod 35 on the end portion (such as the right end) needs to be operated to make it slide between the slide seat 31 and the slide rail 32 and push the pawl 33 on the corresponding side to disengage the corresponding one-way ratchet 322, so that the one-way ratchet 322 on this side no longer restricts the movement in this direction, and the pawl 33 on the other side will not restrict the movement in this direction because it is along the direction of its corresponding one-way ratchet 322. At the same time, the two sets of slide seats 31 and slide rails 32 can cooperate to play an auxiliary guiding role in the movement of the movable end 2 to achieve smooth movement of the movable end 2, so that the movable end 2 can be moved conveniently and quickly. After the user releases the operating rod 35, the pawl 33 is reset under the action of the elastic member 34 and returns to the state of restricted movement, thereby realizing the positioning function of the movable end 2 after translation and the positioning function is controllable.

[0042] In the first embodiment, the movable end 2 is shown to move horizontally on the upper surface of the fixed end 1, that is, the movable end 2 is on the upper side and the fixed end 1 is on the lower side, and the slide 31 is installed on the lower surface of the movable end 2 and the slide rail 32 is installed on the upper surface of the fixed end 1. It is foreseeable that in other embodiments, the slide 31 may be installed on the upper surface of the fixed end 1 and the slide rail 32 may be installed on the lower surface of the movable end 2, and it is only necessary to exchange the corresponding installation structures described below.

[0043] The two groups of translation positioning components 3 are centrally symmetric on a plane parallel to the assembly surface between the fixed end 1 and the movable end 2 , that is, 180° rotationally symmetric.

[0044] See also Figure 1 and Figure 4The upper surface of the fixed end 1 is provided with a first mounting groove 11, and the slide rail 32 is screwed in the first mounting groove 11; the lower surface of the movable end 2 is provided with a second mounting groove 21, and the slide seat 31 is screwed in the second mounting groove 21, and the two ends of the second mounting groove 21 extend toward the two ends of the movable end 2 to form a movable groove 22, and the slide rail 32 is movably matched in the movable groove 22 as the movable end 2 and the fixed end 1 move relative to each other. By designing the first mounting groove 11 and the second mounting groove 21, the embedded installation of the slide rail 32 and the slide seat 31 can be realized respectively, so that the gap between the opposite surfaces of the movable end 2 and the fixed end 1 can be designed to be smaller; at the same time, the movable groove 22 can provide a clearance space for the movement of the slide rail 32 relative to the movable end 2 to avoid interference. By means of two pairs of pawls 33 in opposite directions and the one-way ratchet teeth 322, the movement of the movable end 2 can be limited without pressing the operating rod 35. When the operating rod 35 is pressed, in order to prevent the movable end 2 from moving excessively and falling off the fixed end 1, a limiting design can be made in the movable groove 22, such as installing a limiting pin, a protrusion to form a block, etc., so that when the movable end 2 and the fixed end 1 move relative to each other, the end of the slide rail 32 will eventually abut against the limiting design, thereby limiting the moving stroke of the movable end 2.

[0045] One end of the slide seat 31 is provided with a slide seat installation groove 311 , and one end of the pawl 33 is rotatably engaged in the slide seat installation groove 311 via a rotating shaft 36 .

[0046] Furthermore, the elastic member 34 is a torsion spring, which is sleeved on the rotating shaft 36, and its two ends respectively abut against the sliding seat 31 and the pawl 33; a step 312 for the end of the torsion spring to abut is provided in the sliding seat installation groove 311.

[0047] At the same time, a blocking rod 313 is arranged in the above-mentioned slide mounting groove 311, and a blocking arm 331 is arranged at one end of the pawl 33. When the pawl 33 is pushed by the operating rod 35, it can movably abut against the blocking rod 313, so that the blocking rod 313 can limit the rotation angle of the pawl 33, and the rotation angle can meet the requirement that the pawl 33 disengages from the one-way ratchet 322.

[0048] The upper edges of both side walls of the groove 321 are recessed to form a slide rail groove 323, which matches the shape of the operating rod 35. The operating rod 35 slides in the slide rail groove 323 without contacting the one-way ratchet 322. The slide seat 31 is slidably sleeved on the slide rail 32 and prevents the operating rod 35 from leaving the slide rail groove 323.

[0049] Furthermore, a protrusion 351 is protruded from the surface of the operating rod 35, and a retaining rib 314 opposite to the protrusion 351 is provided in the sliding seat 31. The retaining rib 314 can prevent the operating rod 35 from being pushed out of the sliding seat 31 when the pawl 33 is reset by the elastic force of the elastic member 34 and pushes the operating rod 35 back, thereby ensuring structural stability.

[0050] The end of the operating rod 35 that movably abuts against the ratchet 33 is provided with an inclined surface 352. By designing the inclined surface 352, the operating rod 35 can be pushed more easily and the ratchet 33 can be rotated to disengage from the one-way ratchet 322.

[0052] The second embodiment discloses a car armrest box structure, including the above-mentioned two-way translation positioning mechanism, the fixed end 1 is a box body 1a, the movable end 2 is a box cover 2a, the box body 1a is provided with a storage slot 12; two groups of translation positioning components 3 are respectively arranged on both sides of the storage slot 12.

[0053] refer to Figure 5 The third embodiment of the utility model is shown.

[0054] The third embodiment discloses a sliding door structure, including the above-mentioned two-way translation positioning mechanism, wherein the fixed end 1 is a door bottom frame 1b, the movable end 2 is a sliding door 2b, and the bottom of the sliding door 2b is provided with a roller 4 that rolls on the door bottom frame 1b.

[0055] refer to Figure 6 The fourth embodiment of the present utility model is shown.

[0056] The fourth embodiment discloses a sliding window structure, including the above-mentioned bidirectional translation positioning mechanism, wherein the fixed end 1 is the window bottom frame 1c, the movable end 2 is the sliding window 2c, and the bottom of the sliding window 2c is provided with a roller 4 that rolls on the window bottom frame 1c.
