DETAILED DESCRIPTION

[0030] In order to make the technical problems, technical schemes and beneficial effects of the utility model clearer and more apparent, the utility model will be further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model and are not used to limit the utility model.

[0031] In the claim, description and above-mentioned drawings of the utility model, unless otherwise explicitly limited, the terms such as "first", "second" or "third" are used only to distinguish different objects, and are not used to describe a specific order.

[0032] Please refer to Figures 1 to 11 , now the cover plate pressing unlocking mechanism provided by the utility model will be described. The cover plate pressing unlocking mechanism is installed on the base body to lock the cover plate 7 closed on the base body window, comprising: a housing 1, a force transmission rod 2 and an unlocking lever 4, the housing 1 has a first guide hole 11 extending in a first direction and a second guide hole extending in a second direction, the first direction is perpendicular to the second direction; the force transmission rod 2 partially extends into the first guide hole 11 and has a degree of freedom moving in the first direction, a first elastic member 5 is arranged between the force transmission rod 2 and the housing 1 to reset in the first direction; the unlocking lever 4 partially extends into the second guide hole and partially protrudes outside the housing 1; a second elastic member 6 is arranged between the unlocking lever 4 and the housing 1 to reset after unlocking; the force transmission rod 2 pushes the unlocking lever 4 to retract into the housing 1 along the second guide hole, and the unlocking cover plate 7 is disengaged.

[0033] The cover plate pressing unlocking mechanism has the beneficial effects that compared with the prior art, the fixing of the cover plate 7 of the application discards the connecting mode of the buckle 17 clamping connection, and instead selects the connecting mode of the locking of the unlocking lever 4, in the state that the force transmission rod 2 is not stressed, the unlocking lever 4 is also not stressed, and the unlocking lever 4 is locked with the cover plate 7 under the action of the elastic force reset of the second elastic member 6; when the cover plate 7 is disassembled, it can be unlocked by pressing, external force is applied to the force transmission rod 2, and is transmitted to the unlocking lever 4 through the force transmission rod 2, the second elastic member 6 is compressed to push the unlocking lever 4 to retract into the shell 1 along the second guide hole, the unlocking lever 4 is separated from the cover plate 7, and the cover plate 7 can be conveniently taken down after the cover plate 7 is released from the constraint of the unlocking lever 4.

[0034] The cover plate 7 unlocking mode only needs to press the force transmission rod 2 with the hand, the unlocking lever 4 can be driven to move linearly in the second direction, the cover plate 7 is in a free state without locking, and therefore the cover plate 7 can be taken down without the aid of tools, so that disassembly will not cause deformation of the unlocking lever 4 and the cover plate 7, and the risk of scratching the appearance of the cover plate 7 is also avoided; when the cover plate 7 is installed, the unlocking lever 4 is retracted by pressing, the cover plate 7 is placed into the window, and the hand is released, the unlocking lever 4 can be extended to lock the cover plate 7 under the reset action of the second elastic member 6, and since the unlocking lever 4 and the cover plate 7 are not deformed during disassembly, the appearance of the cover plate is not damaged, so that the firmness and appearance quality of the cover plate 7 after reinstallation are ensured.

[0035] Explanatorily, the main difference between the unlocking mode of the application and the clamping mode of the buckle 17 is that the force transmission rod 2 and the unlocking lever 4 of the application only make linear motion during the unlocking movement process and the reset locking movement process of releasing force, and the force transmission rod 2 and the unlocking lever 4 are not provided with the clamping hooks provided on the buckle 17, and the force transmission rod 2 and the unlocking lever 4 do not need to be elastically deformed; and the buckle 17 is deformed during clamping and disassembly, and thus the phenomenon that the buckle 17 is deformed and fails during disassembly is caused.

[0036] Therefore, the locking of the cover plate 7 of the application can be applied to vehicles, mechanical equipment and electrical appliances, which are not listed one by one; and therefore, the base body mentioned in the text can be a vehicle body sheet metal, a mechanical equipment or an electrical appliance.

[0037] And for the locking of the cover plate 7, the following embodiments are given in the text, embodiment 1, for occasions where only the cover plate 7 needs to be rotated to open, a pressing locking mechanism can be arranged on the side opposite to the rotating shaft of the cover plate 7, and the cover plate 7 can be flipped open by pressing the force transmission rod 2.

[0038] In the embodiment 2, the pressing locking mechanism can be arranged on both sides of the cover plate 7 symmetrically, and only a locking hole or a locking plate 73 capable of abutting against the unlocking lever 4 needs to be arranged on the cover plate 7, and the buckle 17 does not need to be arranged on the cover plate 7, so that when the cover plate 7 is disassembled and removed after the pressing unlocking, the cover plate 7 will not be deformed, and the unlocking lever 4 will not be deformed, and the unlocking lever 4 and the cover plate 7 will not be deformed when disassembled, and the appearance of the cover plate will not be damaged, so that the firmness and appearance quality of the cover plate 7 after reinstallation are ensured. Of course, in this case, when the outer surface of the cover plate 7 is flush with the outer surface of the base body after being covered, the disassembly is still inconvenient due to the very small gap between the cover plate 7 and the base body.

[0039] The embodiment 3 is that a reset spring is arranged between the cover plate 7 and the base body, when the cover plate 7 is locked, the cover plate 7 also compresses the reset spring, the reset spring stores energy, when the cover plate 7 is unlocked, the cover plate 7 is not restricted by the unlocking lever 4, at this time, the cover plate 7 can be lifted up under the action of the reset spring releasing the elastic force, so that the cover plate 7 is separated from the window, thereby the cover plate 7 can be conveniently disassembled and removed, the unlocking lever 4 and the cover plate 7 are not deformed when disassembled, and the appearance of the cover plate is not damaged, so that the firmness and appearance quality of the cover plate 7 after reinstallation are ensured.

[0040] Another case is the embodiment 4, as described in the embodiments below, a disassembly gap 71 can be arranged at the edge of the cover plate 7, and the cover plate 7 can be disassembled and removed by applying force to the cover plate 7 from the disassembly gap 71 outward, so that the cover plate 7 and the unlocking mechanism are not deformed, damaged or scratched.

[0041] For example, when the pressing unlocking mechanism is installed on the trailer hook cover plate 7, the first direction is the same as the front-rear direction of the vehicle body, and the second direction can be the same as the up-down direction of the vehicle body or the left-right direction of the vehicle body. Figure 3 The first direction and the second direction are shown, for example, when the pressing unlocking mechanism is installed on the trailer hook cover plate 7, the first direction is the same as the front-rear direction of the vehicle body, and the second direction can be the same as the up-down direction of the vehicle body or the left-right direction of the vehicle body.

[0042] In some embodiments, referring to Figure 3 and Figure 4The force transmission rod 2 is provided with a clearance hole 21 to allow the unlocking rod 4 to pass during unlocking. When the cover plate 7 is unlocked, the unlocking rod 4 will retract into the housing 1 along the second direction under the pushing force of the force transmission rod 2 in the first direction. The axis of the force transmission rod 2 along the first direction is perpendicular to and intersects the axis of the unlocking rod 4 along the second direction. Therefore, the clearance hole 21 is provided on the force transmission rod 2 to provide clearance space for the unlocking rod 4 to retract into the housing 1. Of course, since the force transmission rod 2 can move back and forth in the first direction, while the unlocking rod 4 does not move in the first direction, the clearance hole 21 needs to have a certain length in the first direction. This length needs to be greater than or equal to the stroke of the force transmission rod 2 in the first direction to ensure that the force transmission rod 2 can unlock the unlocking rod 4.

[0043] In some embodiments, see Figure 3 As shown, a lower limiting surface 12 is provided inside the first guide hole 11, and an upper limiting surface 22 is provided on the force transmission rod 2; the first elastic element 5 is limited between the upper limiting surface 22 and the lower limiting surface. The lower limiting surface 12 inside the first guide hole 11 has a limiting effect on the stroke of the force transmission rod 2.

[0044] The following explanation, using the first direction as vertical and the second direction as front and back, details the operation of the force transmission rod and the unlocking rod, as well as the operation of the first elastic element 5 and the second elastic element 6: When the cover is locked, the first elastic element 5 is compressed due to the limit of the upper limit surface 22 and the lower limit surface 12. When unlocking, the force transmission rod 2 is pressed down by hand. When the force transmission rod 2 is pressed and moves downward along the first direction, the first elastic element 5 is compressed by the upper limit surface 22, and the lower end of the first elastic element 5 abuts against the lower limit surface 12. When compressed, it stores energy. When the force transmission rod pushes the unlocking rod to retract, the cover is unlocked. After releasing the hand, the pressing force on the force transmission rod 2 is released, and the first elastic element 5 elastically resets and pushes the force transmission rod 2 upward. As the force transmission rod 2 moves downward under force and pushes the unlocking rod 4 to move back and forth, the unlocking rod 4 also compresses the second elastic element to store energy. When the pressure on the force transmission rod 2 is released, the constraint on the unlocking rod 4 is also released, and the unlocking rod 4 will also pop out to the locked state under the elastic force of the second elastic element 6.

[0045] Combination Figure 3 In this application, the distance between the upper limit surface 22 and the lower limit surface 12 constitutes the stroke S1 of the linear reciprocating motion of the force transmission rod 2. The lower limit surface 12 is also the limit position of the force transmission rod 2 compressing the first elastic element 5 along the first direction, which is defined as the lower limit position. In this application, the limit position of the linear reset and spring-up motion of the force transmission rod 2 is the cover 3 that is closed on the housing 1. That is, the position of the cover 3 abutting against the upper surface of the thrust arm 23 constitutes the limit position of the reset and spring-up of the force transmission rod 2. For ease of understanding, it is correspondingly defined as the upper limit position.

[0046] Combination Figure 3As shown, the first guide hole 11 is a stepped hole, and a step is formed to constitute a lower limit surface 12; the force transmission rod 2 is divided into two segments with different diameters to form an upper limit surface 22. The first elastic member 5 is a spring sleeved on the force transmission rod 2.

[0047] In some embodiments, referring to Figures 5 to 8 , the inner side of the shell 1 is provided with an anti-rotation limiting groove 16 extending in the first direction, and the force transmission rod 2 is provided with a limiting rib 25 in sliding cooperation with the anti-rotation limiting groove 16. When the first guide hole 11 is a circular hole, the force transmission rod 2 will have a rotating phenomenon when moving in the first direction, which may cause the failure of force transmission to the unlocking lever 4 and the unlocking cannot be achieved, while the limiting rib 25 on the force transmission rod 2 can only move linearly along the anti-rotation limiting groove 16, avoiding the risk of rotation of the force transmission rod 2 when moving.

[0048] In this embodiment, two anti-rotation limiting grooves 16 are symmetrically arranged on the shell 1, and the force transmission rod 2 is symmetrically provided with two limiting ribs 25.

[0049] Referring to Figure 4 , the shell 1 has a shell bottom, and the first guide hole 11 is a guide cylinder extending outward from the shell bottom in the first direction, at this time, the limiting rib 25 on the force transmission rod 2 and the shell bottom of the shell 1 also constitute a stroke limiting structure, when the force transmission rod 2 is pressed and moves, the limiting rib 25 abuts against the shell bottom of the shell 1, and the unlocking lever 4 also retracts to be in the unlocking state.

[0050] In another embodiment, the first guide hole 11 can be a polygonal hole, and the corresponding force transmission rod 2 is polygonal, at this time, the force transmission rod 2 and the first guide hole 11 have at least a mutual cooperation anti-rotation surface, even if the limiting rib 25 is not arranged, the direction of movement of the force transmission rod 2 can be guided, and the rotation of the force transmission rod 2 can be avoided.

[0051] In some embodiments, referring to Figure 3 , Figure 7 and Figure 8 , the force transmission rod 2 is provided with a thrust arm 23 extending in the second direction, and the thrust arm 23 is provided with a thrust inclined surface 231 inclined towards the unlocking lever 4; the unlocking lever 4 is provided with a bearing arm 42 extending in the first direction, and the bearing arm 42 is provided with a bearing inclined surface 421 tangent to the thrust inclined surface 231. The thrust inclined surface 231 of the force transmission rod 2 is in abutment with the bearing inclined surface 421 of the unlocking lever 4, when the pressing force received by the force transmission rod 2 is applied to the bearing inclined surface 421, the force decomposition forms a component force in the second direction and a component force in the first direction, and the bearing inclined surface 421 provides space for the movement of the force transmission rod 2 in the first direction when pushing the unlocking lever 4 to move in the second direction.

[0052] In some embodiments, referring to Figures 6 to 8, the second guide hole is provided with an anti-falling stop face 18, and the unlocking lever 4 is formed with an anti-falling matching face 43 which abuts against the anti-falling stop face 18 when the unlocking lever 4 is reset and pops out to the locking state. When the unlocking lever 4 is reset and pops out to the locking state under the elastic force of the second elastic member 6, the anti-falling matching face 43 on the unlocking lever 4 abuts against the anti-falling stop face 18, so as to prevent the unlocking lever 4 from falling out of the shell 1.

[0053] In some embodiments, the second elastic member 6 is a spring which is sleeved on the unlocking lever 4 and is telescopic along the second direction.

[0054] In some embodiments, referring to Figure 3 , the second guide hole is further provided with a rear limiting face 13, and the unlocking lever 4 is provided with a front limiting face 41, and the second elastic member 6 is limited between the front limiting face 41 and the rear limiting face 13. When the unlocking lever 4 is retracted, the front limiting face 41 abuts against the second elastic member 6, and the second elastic member 6 is limited by the rear limiting face 13, so that the second elastic member 6 stores energy. When the pressure on the unlocking lever 4 is removed, the unlocking lever 4 will be extended again under the releasing elastic force of the second elastic member 6 to the locking state. The rear limiting face 13 and the anti-falling stop face 18 correspond to each other, and the distance therebetween constitutes a movement stroke S2 of the unlocking lever 4 in the unlocking and reset locking states, and limits the retracted position of the unlocking lever 4.

[0055] In some embodiments, the rear limiting face 13 is a plane in the shell 1 opposite to the anti-falling stop face 18; the front limiting face 41 is a plane of a force bearing arm 42 which is integrally connected with the unlocking lever 4 and opposite to the rear limiting face 13; the unlocking lever 4 is also divided into two sections by the force bearing arm 42, one section close to the force transmission lever 2 is defined as a rear lever section which is cylindrical, and the second elastic member 6 is sleeved on the rear lever section; the force bearing arm 42 is partly in the shell 1 and partly exposed outside the shell 1, and is defined as a front lever section which is rectangular in the cross section perpendicular to the second direction, so as to provide a larger contact plane between the unlocking lever 4 and the shell 1, to ensure the stability of the linear operation of the unlocking lever 4 and the firmness of the locking, and to have the function of preventing rotation.

[0056] In some embodiments, referring to Figures 1 to 6The shell 1 is provided with a cover 3, and the cover 3 is provided with a avoiding port for avoiding the force transmission rod 2; the cover 3 and the shell 1 are combined to form a second guide hole. The cover 3 has a protection effect on the structure in the shell 1, and the cover 3 is also a limiting piece for the outward movement of the force transmission rod 2, and the cover 3 limits the movement of the thrust arm 23 arranged in the second direction, thereby limiting the movement of the force transmission rod 2. On the other hand, the installation position of the unlocking rod 4 is provided with a guide channel on the shell 1, and the combination of the cover 3 and the shell 1 forms a second guide hole, that is, the cover 3 limits the movement of the unlocking rod 4 in the first direction, and the unlocking rod 4 can only move in the second direction.

[0057] In order to facilitate the pressing of the force transmission rod 2, a button 24 with a larger cross section than the force transmission rod 2 is arranged at the end of the force transmission rod 2, the button 24 is arranged in the avoiding port, and the outer surface of the button 24 is flush with the outer surface of the cover 3, so as to ensure that the mechanism has a good appearance.

[0058] The fixing mode of the cover 3 and the shell 1 is combined Figures 9 to 11 It can be understood that the clamping connection mode of the buckle 17 can be adopted, because the cover 3 is generally not disassembled, the size of the cover 3 is small, and the clamping connection of the buckle 17 can also save space. In order to ensure the stable and reliable position connection relationship between the cover 3 and the shell 1, a supporting table 15 for supporting the cover 3 is arranged in the shell 1; at the same time, a limiting hole 14 and a limiting column that are matched with each other are arranged between the shell 1 and the cover 3, and the limiting hole 14 and the limiting column have a guiding effect on the installation of the cover 3, and here the limiting hole 14 is arranged on the shell 1, and the limiting column is arranged on the cover 3, and vice versa.
