Description

Technical Field

[0001] The utility model relates to the field of object locking and supporting, in particular to an object fixing mechanism and an object fixing device. Background Art

[0002] At present, box-type objects are prone to slipping and bumping during transportation or movement, which may lead to safety hazards or abnormal damage. For example, in the field of robotics, composite robots need to deploy battery packs inside, but in actual deployment, the deployment and fixation of the battery packs are extremely difficult due to factors such as small space. The whole process is time-consuming and labor-intensive, and the fixing effect is poor, making it easy to be damaged. Utility Model Content

[0003] The main purpose of the utility model is to provide an object fixing mechanism and an object fixing device to solve the problem in the prior art that lithium batteries are difficult to deploy and fix in a narrow space.

[0004] In order to achieve the above-mentioned purpose, according to one aspect of the utility model, there is provided an object fixing mechanism, including a base, a seesaw, and a stop assembly. The seesaw is rotatably connected to the base, the seesaw has a first end and a second end, and along the direction in which the object slides onto the seesaw, the first end, the rotation axis of the seesaw, and the second end are arranged in sequence. The stop assembly is located at the first end, and the first end rises when the second end is pressed down by the object. When the object completely slides to the side of the stop assembly close to the second end, the stop assembly is located on the sliding path of the object and blocks the object from moving in the opposite direction.

[0005] Furthermore, the stop assembly includes a stop block and a second elastic member. The stop block is movably arranged at the first end. When the first end rises, the stop block has a release state that is lower than or level with the upper surface of the seesaw and a stop state that protrudes above the upper surface of the seesaw. When the stop block is in the stop state, it is located on the sliding path of the object and blocks the object. The second elastic member abuts against the stop block and provides elastic force for the stop block to move toward the stop state.

[0006] Furthermore, the first end has a downward recess, the stopper is movably arranged at the recess, and the stopper is completely accommodated in the recess when it is in a released state, and the top end of the stopper protrudes from the recess when it is in a stopped state.

[0007] Furthermore, the stop assembly also includes a retaining member, which is connected to the stopper, and the retaining member has a retaining structure. When the stopper is in a released state, the retaining structure cooperates with the rocker stopper and retains the stopper in the released state.

[0008] Furthermore, the retaining member is rotatably connected to the stopper, and the bottom end of the retaining member has a hook portion as a retaining structure. When the stopper is in a released state, the hook portion is hooked on the lower surface of the seesaw and prevents the stopper from moving upward.

[0009] Furthermore, the stop assembly also includes a reset member, which is arranged on the base and located on the downward movement path of the retaining member. When the first end moves downward a predetermined distance, the retaining member abuts against the reset member, and the retaining member moves under the stop of the reset member and releases the stop cooperation with the rocker.

[0010] Furthermore, the retaining member includes a first section and a second section that are bent in series, the first section extends laterally and is located above the reset member, the second section extends longitudinally, the retaining structure is located at the bottom end of the second section, and the bending point between the first section and the second section is rotatably connected to the stopper.

[0011] Furthermore, the object fixing mechanism also includes a first elastic member, which is located at the second end and provides an elastic force for the second end to rise upward.

[0012] Furthermore, the object fixing mechanism also includes a rolling member, which is rotatably arranged at the second end, and at least a portion of the rolling member protrudes from the upper surface of the seesaw and supports the object.

[0013] According to another aspect of the utility model, there is provided an object fixing device, comprising a base, the above-mentioned object fixing mechanism, and a limiting mechanism, wherein the base of the object fixing mechanism is installed on the base, the limiting mechanism is connected to the base, and the limiting mechanism comprises a limiting member, and when the object is located on the object fixing mechanism, the limiting member and the stopper assembly of the object fixing mechanism are respectively located on two opposite sides of the object, and respectively cooperate with the stoppers on the two opposite sides of the object, and lock the position of the object.

[0014] By applying the technical solution of the utility model, by setting a seesaw and a stopper assembly, objects such as a battery pack can slide onto the object fixing mechanism and automatically lock, without excessive human participation and operation, and the purpose of self-locking is achieved completely by the deadweight of the battery pack itself, without the need for other driving structures, and the design is simpler and more convenient, avoiding complex design, and effectively improving the convenience of the structure. Specifically, the battery pack slides from the left side of the object fixing mechanism, that is, the side where the stopper assembly is set, to the right along the seesaw. As the battery pack slides, the center of gravity moves from left to right. When the center of gravity reaches the right side of the rotation axis of the seesaw, the seesaw rotates, so that the first end rises and the second end falls. The rise of the first end drives the stopper assembly to rise. When the battery pack completely passes over the stopper assembly, the stopper assembly is located on the movement path of the battery pack's reverse movement, thereby playing a role in hindering the reverse movement of the battery pack, so that the battery pack cannot slide out in the reverse direction at the first end, and the battery pack is supported and locked to the object fixing mechanism. The above whole process only requires pushing the battery pack onto the rocker to automatically lock it, without the need for excessive human participation and operation, which greatly improves the convenience of operation. Even in cases where the space is small, personnel only need to push the battery pack in from the outside, so that mobile collaborative robots and other scenes with small spaces can also flexibly, quickly and conveniently deploy and fix the battery pack. The whole process completes the purpose of adaptively locking the battery in the equipment by mechanical means, which reduces the frequency of failures compared to electronic control methods.

[0028] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0029] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0030] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention.

[0031] In order to solve the problem in the prior art that it is difficult to deploy and fix an object in a narrow space, the utility model provides an object fixing mechanism and an object fixing device.

[0032] like Figures 1 to 5The object fixing mechanism shown includes a base 10, a seesaw 20, and a stop assembly 30. The seesaw 20 is rotatably connected to the base 10. The seesaw 20 has a first end and a second end. Along the direction in which the object slides onto the seesaw 20, the first end, the rotation axis of the seesaw 20, and the second end are arranged in sequence. The stop assembly 30 is located at the first end. When the second end is pressed down by the object, the first end rises. When the object completely slides to the side of the stop assembly 30 close to the second end, the stop assembly 30 is located on the sliding path of the object and blocks the object from moving in the opposite direction.

[0033] In this embodiment, by setting the seesaw 20 and the stopper assembly 30, objects such as the battery pack can slide onto the object fixing mechanism and automatically lock, without excessive human participation and operation, and the self-locking purpose is achieved completely by the deadweight of the battery pack itself, without the need for other driving structures, the design is simpler and more convenient, avoiding complex design, and effectively improving the convenience of the structure. Specifically, the battery pack is Figure 1 The left side of the object fixing mechanism, i.e., the side where the stop assembly 30 is provided, slides to the right along the rocker 20. As the battery pack slides, the center of gravity moves from left to right. When the center of gravity reaches the right side of the rotation axis of the rocker 20, the rocker 20 rotates, so that the first end rises and the second end falls. The rise of the first end drives the stop assembly 30 to rise as well. When the battery pack completely passes over the stop assembly 30, the stop assembly 30 is located on the movement path of the battery pack in the reverse direction, thereby hindering the reverse movement of the battery pack, so that the battery pack cannot slide out in the reverse direction at the first end, and the battery pack is supported and locked to the object fixing mechanism. The above-mentioned whole process only requires pushing the battery pack onto the rocker 20 to automatically lock it, without much human participation and operation, thereby greatly improving the convenience of operation. Even in the case of narrow space, personnel only need to push the battery pack in from the outside, so that mobile collaborative robots and other scenes with narrow space can also flexibly, quickly and conveniently deploy and fix the battery pack. The whole process completes the purpose of adaptively locking the battery in the equipment by mechanical means, which reduces the frequency of failures compared to electronic control methods.

[0034] It should be noted that this embodiment is described by taking the object fixing mechanism applied to the deployment of a battery pack as an example, and accordingly, the object is the battery pack. Of course, the object fixing mechanism can also be applied to other scenarios, in which case the object is a corresponding object.

[0035] The object fixing mechanism in this embodiment also includes a first elastic member 40, which is located at the second end and is arranged between the base 10 and the seesaw 20. The first elastic member 40 can provide an elastic force for the second end to rise upward, so that when the battery pack is not pushed onto the seesaw 20 or after the battery pack is pulled out, the second end can remain in an upward state or automatically return to an upward state under the action of the first elastic member 40, so as to prepare for the subsequent deployment of the battery pack. Specifically, when the battery pack slides from left to right, as the center of gravity moves to the right, the first elastic member 40 is compressed by pressure, so that the second end falls and the first end rises. When the battery pack slides from right to left, as the center of gravity moves to the left, the pressure on the first elastic member 40 is reduced, so that the second end rises and the first end falls. The first elastic member 40 in this embodiment adopts a spring, which is arranged longitudinally, and its upper and lower ends are respectively in contact with the bottom surface of the second end and the top surface of the base 10. Of course, the first elastic member 40 can also use other elastic elements to achieve the effect of automatic reset of the second end. At the same time, the first elastic member 40 may be provided with structures such as guide columns and guide grooves as needed.

[0036] In an embodiment not shown in the figure, the first elastic member 40 is not provided. In this case, the rotation axis of the seesaw 20 may not be set at the exact center in the length direction, but may be slightly tilted toward the second end, so that the seesaw 20 can be automatically reset by its own gravity, or the tilt state of the seesaw 20 can be adjusted by a person pressing the seesaw 20.

[0037] The stopper assembly 30 in this embodiment includes a stopper 31 and a second elastic member 32. Figure 2 and Figure 3 As shown, the stopper 31 is movably arranged at the first end and can move up and down. Therefore, when the first end rises, the stopper 31 has a release state lower than or level with the upper surface of the seesaw 20 and a stop state protruding from the upper surface of the seesaw 20. When the stopper 31 is in the stop state, it is located on the sliding path of the battery pack and blocks the battery pack, limiting the reverse movement of the battery pack. The second elastic member 32 abuts against the stopper 31 and provides elastic force for the stopper 31 to move toward the stop state, so that the stopper 31 can move from bottom to top, and then can stop the battery pack to prevent the battery pack from moving back and forth in the device. Specifically, in the stop state, the stopper 31 is acted upon by the upward elastic force of the second elastic member 32, and the stopper 31 is higher than the upper surface of the seesaw 20, so that the stopper assembly 30 can lock the battery pack on the seesaw 20. When the stopper 31 is pressed by an external force, the stopper 31 and the second elastic member 32 move downward, so as to be lower than the upper surface of the seesaw 20, and release the lock on the battery pack. The second elastic member 32 in this embodiment is a spring, and other elastic elements can also be used as long as they can provide appropriate elastic force for the stopper 31. It should be noted that the upper surface of the seesaw 20 in this embodiment refers to the surface of the upper side of the seesaw 20 that contacts the battery pack and supports the battery pack.

[0038] The stopper 31 of this embodiment preferably covers the entire width of the rocker 20 to ensure the stopping effect on the battery pack, and the stopper 31 can be a block structure as a whole, or a structure with a groove on the upper surface. As long as it can stop the battery pack, the specific shape can be set according to needs.

[0039] The first end of this embodiment has a downward recessed portion, which is located at the leftmost side of the first end and is adjacent to the upper surface and three side surfaces of the first end. Of course, the recessed portion can also be set at the non-end surface of the first end, in which case the recessed portion is only connected to the upper surface and two opposite side surfaces of the first end. The stopper 31 is arranged at the recessed portion in a liftable manner, so that the stopper 31 can move in the up and down directions of the recessed portion, and the stopper 31 is completely accommodated in the recessed portion when it is in the released state, so that the upper surface of the stopper 31 is lower than the upper surface of the rocker 20, thereby facilitating the smooth insertion of the battery pack and preventing people from accidentally injuring their hands when pulling the battery. When the stopper 31 is in the stopping state, the top end protrudes from the recessed portion, so that the battery pack can be locked on the rocker 20.

[0040] The bottom of the stopper 31 of this embodiment has a longitudinally arranged guide column, and correspondingly, a guide hole is arranged on the bottom surface of the recess, and the guide column is arranged in the guide hole, so that the stopper 31 can only move up and down, ensuring the reliability and stability of its movement. At the same time, in order to prevent the stopper 31 from slipping out of the recess when moving upward, a flange is arranged at the bottom end of the guide column in this embodiment, and the diameter of the flange is larger than the diameter of the guide hole, so that the guide column can always remain in the guide hole, ensuring the reliability of the overall movement of the stopper 31.

[0041] like Figure 8 and Fig. 9 As shown, the stopper assembly 30 in this embodiment also includes a retaining member 33, which is connected to the stopper 31 and can drive the stopper 31 to move up and down. The retaining member 33 has a retaining structure. When the stopper 31 is in the released state, the retaining structure cooperates with the stopper of the seesaw 20, and the retaining structure is limited by the lower surface of the seesaw 20, so that the retaining structure is limited to the lower surface of the seesaw 20 and cannot move upward, so that the stopper 31 cannot move upward, thereby keeping the stopper 31 in the released state. The main function of the retaining member 33 is that when the battery pack needs to be taken out, the stopper 31 can be kept in the released state by the retaining member 33, so as to facilitate the removal of the battery pack.

[0042] Specifically, the retaining member 33 in this embodiment is rotatably connected to the stopper 31. The retaining member 33 is rotatably arranged on a side of the stopper 31 away from the second end, that is, on the left side of the stopper 31. The retaining member 33 can not only be driven by a downward force to move the stopper 31 downward, so that the retaining structure is limited, thereby putting the stopper 31 in a released state, but also can be rotated by an upward force, thereby releasing the limited state of the retaining structure, so that the stopper 31 returns to a stopped state. The bottom end of the retaining member 33 has a hook portion as a retaining structure. When the retaining member 33 moves downward, the hook portion can be hooked on the lower surface of the seesaw 20 and hinder the upward movement of the stopper 31, so that the stopper 31 is kept in a released state, so that the upper surface of the stopper 31 is kept lower than the upper surface of the seesaw 20.

[0043] The force of the retaining member 33 to release the retaining effect on the stopper 31 upwards can be manually applied by a person or automatically achieved. This embodiment adopts the latter. Specifically, the stopper assembly 30 in this embodiment also includes a reset member 34, such as Figure 3 and Fig.10 As shown, the reset member 34 is provided on the base 10, higher than the surface of the base 10, and can be set in the shape of a pin or a protrusion, and is located on the downward movement path of the retaining member 33. When the first end moves downward by a predetermined distance, the retaining member 33 abuts against the reset member 34, and the retaining member 33 moves under the stop of the reset member 34 and releases the stop cooperation with the seesaw 20, that is, the downward movement of the first end drives the retaining member 33 to move downward. When the retaining member 33 abuts against the reset member 34 after moving a certain distance, the first end continues to move downward, and the reset member 34 lifts the pressing end of the retaining member 33, so that the retaining member 33 rotates, and its hook portion is separated from the lower surface of the seesaw 20. The retaining member 33 no longer releases the stop block 31, and the stop block 31 moves from bottom to top under the action of the second elastic member 32 and is higher than the seesaw. The upper surface of the plate 20, the stop assembly 30 restores the stop state. In this way, when the battery pack needs to be taken out and replaced, it is only necessary to gently press the lower retaining member 33 by hand. The retaining member 33 cooperates with the rocker 20 to keep the block 31 in the released state. Subsequently, as the battery pack is pulled out, the first end drops and resets. During this process, the reset member 34 acts, and the reset member 34 pushes against the retaining member 33, so that the retaining member 33 is reset, thereby releasing the released state of the block 31. After the battery pack is taken out, the stop assembly 30 will automatically reset without manual reset. The personnel can directly replace and push in the next battery pack, push it into place, and lock it automatically. The whole process only requires the personnel to press the lower retaining member 33 when taking out the battery pack. In other cases, the mechanism itself can automatically lock and reset according to whether there is a battery, thereby reducing the complexity of personnel operation.

[0044] The retaining member 33 in this embodiment includes a first section and a second section that are bent in sequence, the first section extends laterally and is located above the reset member 34, the end of the first section is the pressing end of the retaining member 33, the second section extends longitudinally, the retaining structure is located at the bottom end of the second section, and the bending point between the first section and the second section is rotatably connected to the stop block 31. In this way, the retaining member 33 as a whole forms an inverted L-shaped structure. When the first section is driven by the downward force of the person to move the stop block 31 downward, the retaining structure moves to the lower surface of the first end of the rocker 20 and cooperates therewith. The lower surface of the rocker 20 limits the retaining structure, so that when there is no external force, the retaining structure is limited to the lower surface of the rocker 20 and cannot move upward under the elastic force of the second elastic member 32, so that the upper surface of the stop assembly 30 is lower than the rocker 20, and the locking state of the battery pack by the stop block 31 is released. When the reset member 34 applies an upward force to the first section, the retaining member 33 rotates around the stop block 31, so that the retaining structure leaves the lower surface of the first end of the rocker 20, and the limiting effect of the rocker 20 on the retaining structure is eliminated. The elastic action of the second elastic member 32 causes the stop block 31 to move from bottom to top, and the stop block 31 is higher than the upper surface of the rocker 20, and the stop block 31 returns to the stopped state.

[0045] The object fixing mechanism in this embodiment also includes a rolling member 50, which is rotatably arranged at the second end. The rotation axis of the rolling member 50 is arranged horizontally and perpendicular to the direction in which the battery pack slides on the seesaw 20, which guides the movement of the battery pack and reduces friction. At least a portion of the rolling member 50 protrudes from the upper surface of the seesaw 20 and supports the battery pack. Preferably, the rolling member 50 is 0.5-2 mm higher than the upper surface of the seesaw 20, so that the bottom surface of the battery pack contacts the highest point of the rolling member 50, ensuring that the external force on the seesaw 20 is concentrated at one point, so that the rolling member 50 is given a vertical downward positive pressure under the action of the battery pack's own gravity to overcome the spring force of the first elastic member 40, so that the seesaw 20 is pressed to a horizontal state, thereby fully achieving the purpose of torque balance of the seesaw 20. The rolling member 50 can be a roller or other structure.

[0046] The object fixing mechanism in this embodiment adopts a modular design, which is convenient for quick installation and deployment in the equipment, and the total height of the structure is only 30-50mm, which can be directly installed on the bottom of the equipment. The installation is simple, which effectively saves space, and the structural design is simple and the cost is low.

[0047] This embodiment also provides an object fixing device, such as Figure 6 and Figure 7As shown, it includes a base 60, the above-mentioned object fixing mechanism, and a limiting mechanism 70. The base 10 of the object fixing mechanism is installed on the base 60. The limiting mechanism 70 is connected to the base 60. The limiting mechanism 70 includes a limiting member. The limiting member can adopt a structure such as a baffle. The limiting member is higher than the surface of the base 60 to limit the battery pack. When the battery pack is located on the object fixing mechanism, the limiting member and the stopper assembly 30 of the object fixing mechanism are respectively located on the opposite sides of the battery pack, and respectively cooperate with the opposite side stops of the battery pack. In this way, the limiting member and the stopper 31 work together to fix the battery pack on the inner and outer sides of the battery pack, thereby locking the position of the battery pack to prevent the battery pack from moving left and right, and ensure that the position of the battery pack is fixed after deployment.

[0048] In this embodiment, a slide rail structure as a guide component is provided on both sides of the base 60. The slide rail structure is arranged horizontally, and the battery pack slides onto the seesaw 20 through the slide rail structure. When the battery pack is not pushed to the second end, although the stopper 31 at the first end can be higher than the upper surface of the seesaw 20, it is lower than the horizontal plane of the slide rail structure, that is, lower than the lower plane when the battery pack is pushed in, so the stopper 31 will not prevent the battery pack from being pushed in. When the battery pack is pushed in, the first end rises, and the stopper 31 rises to a level higher than the seesaw 20 and the slide rail structure, thereby entering a stop state to stop the battery pack. Based on this, the stop block 31 in the present embodiment that stops the battery pack when it is in the stopping state actually means that when the first end of the seesaw 20 rises, that is, when the seesaw 20 is roughly horizontal, the stop block 31 protrudes from the upper surface of the seesaw 20, thereby being located on the sliding path of the battery pack to achieve a stopping effect. When the first end of the seesaw 20 has not risen, the stop block 31 can always avoid the sliding of the battery pack, and there is no so-called stopping state.

[0049] The specific use process of the object fixing mechanism is as follows:

[0050] The base 10 is installed in the device through the threaded hole. At this time, due to the second end of the rocker 20 Figure 1 A first elastic member 40 is provided between the right end and the base 10, and the first elastic member 40 enables the seesaw 20 to be at the second end when no external force is applied. Figure 1The right end is tilted. At this time, since the stopper 31 is lower than the horizontal plane of the slide rail structure, the stopper 31 will not affect the sliding of the battery pack onto the rocker 20. The personnel push the battery pack from the first end of the rocker 20 onto the rocker 20, and push the battery pack to the second end. When the center of the battery pack passes the rotation axis of the rocker 20, the battery pack abuts against the rolling member 50, and the battery pack gradually presses down the second end so that the second end compresses the first elastic member 40. The second end gradually descends and the first end gradually rises. The stopper 31 abuts against the lower surface of the battery pack until the battery pack is pushed into place. Under the action of the second elastic member 32, the stopper 31 protrudes from the upper surface of the rocker 20. At this time, the stopper 31 also stops the side of the battery pack, so that the battery pack cannot move in the opposite direction, and is thus limited and locked on the rocker 20.

[0051] When the battery pack needs to be taken out, the operator presses down the first section of the retaining member 33 so that the retaining structure of the second section of the retaining member 33 hooks the bottom surface of the rocker 20, thereby keeping the block 31 in the released state. The block 31 no longer stops the movement of the battery pack, so that the battery pack can be pulled out from the rocker 20. During the process of pulling out the battery pack, the pressure of the battery pack on the second end of the rocker 20 is reduced, so that the second end gradually rises under the action of the first elastic member 40, while the first end falls. When the first end falls a certain distance, the lower surface of the first section of the retaining member 33 abuts against the reset member 34. As the battery pack is taken out, the first end continues to fall, and the reset member 34 abuts against the retaining member 33, causing the retaining member 33 to rotate relative to the block 31, thereby causing the retaining structure to disengage from the rocker 20. The retaining member 33 no longer controls the upward movement of the block 31, and the block 31 can automatically rise under the action of the second elastic member 32 until the battery pack is completely separated from the rocker 20. The block can be reset to the stop state, and the entire mechanism is reset, waiting for the next deployment of the battery pack.

[0052] It should be noted that, the multiple in the above embodiments refers to at least two.

[0055] 2. The battery pack can slide onto the object fixing mechanism and lock automatically without excessive human involvement and operation;
