Description

Technical Field

[0001] The utility model relates to the technical field of garden tools, in particular to a flap structure with damping. Background Art

[0002] In the prior art, the battery pack compartment flap of DC products such as grinders, rotary tillers, and lawn mowers mostly uses a spring rebound. When plugging in or out of the battery pack, the spring rebound will cause the flap to flip down and close immediately. The user must use one hand to hold the flap to plug in or out the battery pack. The flap closes very quickly, which poses a risk of pinching the hand. In addition, the noise when the flap closes is relatively loud, resulting in a poor user experience. Utility Model Content

[0003] The purpose to be achieved by the utility model is to provide a flap structure with damping, which solves the problem that the existing flap is automatically closed too quickly, slows down the automatic closing speed of the flap, and provides a better user experience.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a flap structure with damping, comprising a main body, a connecting piece and a cover body, wherein the cover body is rotatably arranged on the main body via the connecting piece and can be automatically closed, a damping chamber with damping grease is arranged on one of the main body and the cover body, a connecting piece connected to the other of the main body and the cover body extends into the damping chamber, and the damping grease provides damping to the connecting piece during the rotation of the cover body.

[0005] After adopting the above technical scheme, the utility model has the following advantages: through the damping grease filled in the damping chamber, when the cover body rotates, the connecting part interacts with the damping grease to generate continuous and uniform resistance, so that the opening and closing action of the cover body becomes smooth and without abruptness, ensuring that the cover body moves slowly and controlled when closing, reducing accidental pinching of fingers and noise during closing, especially when the flip cover structure is applied to the battery compartment, the cover body will not flip down and close immediately, and the large battery pack can be inserted and removed with both hands, which greatly improves the user's operating experience.

[0006] Furthermore, the left and right side walls of the body are both provided with damping chambers, and connecting pieces are both provided between the left and right side walls of the body and the cover body, and the connecting pieces extend into the connecting pieces in the damping chambers on the left and right side walls of the body (10) respectively.

[0007] By adopting the above-mentioned technical solution, the damping chambers on both sides and the damping grease therein mean that when the cover body rotates, both sides are affected by damping, which not only makes the damping effect more uniform, but also can effectively absorb more impact force, making the opening and closing action smoother and softer. Especially for heavier covers, it can effectively reduce the impact force generated when the cover body covers the main body, further reduce the noise generation, and further improve the user experience. It can also achieve force balance during the opening and closing process of the cover body, which helps to reduce distortion or deformation caused by uneven force on one side, and improve the stability and durability of the entire structure.

[0008] Furthermore, the main body is provided with a cover plate and a surrounding plate, the surrounding plate surrounds the connecting member and is spaced apart from the connecting member, the cover plate is covered on the surrounding plate to form a damping chamber, and the cover plate is provided with an opening for the connecting member to pass through.

[0009] By adopting the above-mentioned technical solution, the enclosure plate surrounds the connecting part and is spaced apart from it, and together with the cover plate forms a closed damping chamber, which effectively prevents external dust, moisture or other contaminants from entering the chamber, protects the damping grease from contamination, and extends its service life. At the same time, it also helps to maintain the consistency of the damping effect. In addition, the setting of the cover plate makes it easier to open the damping chamber for inspection or replacement of the damping grease.

[0010] Furthermore, the connecting member includes a rotating shaft connecting member fixedly connected to the main body, a first rotating part located in the damping chamber, and a second rotating part located outside the damping chamber. The first rotating part and the second rotating part are detachably connected. The first rotating part is provided with a rotating shaft hole that cooperates with the rotating shaft, and the second rotating part is transmission-connected to the cover body.

[0011] By adopting the above-mentioned technical solution, the design of the detachable connection between the first rotating part and the second rotating part makes the operation simpler and faster when maintenance or replacement of parts is required. Through the cooperation of the shaft hole and the shaft, and the transmission connection between the second rotating part and the cover body, flexible docking between the connecting part and different components is achieved, which enhances the compatibility with covers or shafts of different specifications, and facilitates adaptation to more diverse application scenarios.

[0012] Furthermore, the first rotating part is provided with an impeller extending into the damping chamber.

[0013] By adopting the above-mentioned technical solution, the impeller has a larger area. When the impeller rotates in the damping chamber, it can more effectively stir the damping grease, making the damping grease more evenly distributed, providing a more stable and controllable damping force, thereby making the opening and closing action of the cover body smoother.

[0014] Furthermore, a sealing ring is provided between the cover plate and the first rotating part. After the cover plate is closed on the enclosure plate, the cover plate and the first rotating part press against the sealing ring together.

[0015] By adopting the above technical solution, the addition of the sealing ring effectively prevents the leakage of the damping grease and ensures the sealing of the damping chamber. Even under long-term use or under different ambient temperatures, the internal damping grease can be kept stable, thereby extending the service life of the damping system.

[0016] Furthermore, a handle is provided on the cover body for easy grasping, and the cover body includes a covering surface and a mounting surface for mounting the handle, the covering surface is staggered from the mounting surface, and the handle is transmission-connected to the second rotating part.

[0017] By adopting the above technical solution, the staggered design effectively avoids the risk of fingers or hands being pinched when operating the handle, especially in the case of fast or forceful operation, thereby ensuring the safety of the user.

[0018] Furthermore, the cover body is provided with a slot, and the second rotating part is provided with a positioning block which is interference fit with the slot.

[0019] By adopting the above technical solution, the interference fit design between the positioning block and the slot ensures the precise position of the second rotating part on the cover body, prevents deviation or shaking during rotation, and improves the accuracy and consistency of the flip cover action. Secondly, the interference fit design simplifies the assembly process, and no additional fixing devices such as screws or pins are required. The assembly can be completed by simply inserting the positioning block into the slot.

[0020] Furthermore, the main body is provided with a heat insulation plate surrounding the enclosure, and a heat insulation gap is provided between the heat insulation plate and the enclosure.

[0021] By adopting the above technical solution, the setting of the heat insulation board effectively isolates the influence of the external ambient temperature on the inside of the damping chamber, especially for those damping greases that are sensitive to temperature or equipment working in extreme temperature difference environments, it can maintain the stability of the damping performance and avoid the weakening or failure of the damping effect due to temperature fluctuations.

[0022] Furthermore, the main body is provided with a limiting rib, and the cover body can rotate relative to the main body to a highest position against the limiting rib.

[0023] By adopting the above technical solution, the limiting rib provides a clear physical stop point, so that the cover can accurately stop at the preset highest position during the opening and closing process, ensuring that each opening and closing reaches a consistent height, preventing excessive flipping, and improving the accuracy and reliability of the operation.

[0040] The following specific embodiments are used to describe the technical solution of the utility model in detail. The following specific embodiments can be combined or replaced with each other according to actual conditions, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0041] like Figures 1 to 9 As shown, the utility model provides a flap structure with damping, which is suitable for battery compartments of products such as crushers, rotary tillers, and lawn mowers. The flap structure includes a main body 10, a connecting piece, and a cover body 20. The cover body 20 is rotatably arranged on the main body 10 through the connecting piece and can be automatically closed. A damping chamber 11 with damping grease is arranged on one of the main body 10 and the cover body 20, and a connecting piece connected to the other of the main body 10 and the cover body 20 extends into the damping chamber 11. The damping grease provides damping to the connecting piece during the rotation of the cover body 20.

[0042] In this embodiment, a counterweight 30 is provided at one end of the cover 20 away from the connection position between the cover 20 and the main body 10. After the cover 111 is opened, the weight of the counterweight 30 can realize that the cover 111 automatically covers the main body 10. A damping chamber 11 is provided on the main body 10. Through the damping grease filled in the damping chamber 11, when the cover 20 rotates, the connecting piece interacts with the damping grease to generate continuous and uniform resistance, so that the opening and closing action of the cover 20 becomes smooth and non-abrupt, ensuring that the cover 20 moves slowly and in a controlled manner when closing, reducing accidental pinching of fingers and noise when closing, especially in the battery compartment, the cover 20 will not flip down and close immediately, and large-volume battery packs can be plugged and unplugged with both hands, which greatly improves the user's operating experience.

[0043] In order to further make the opening and closing action of the cover body 20 smoother, damping chambers 11 are provided on the left and right side walls of the main body 10, and connecting parts are provided between the left and right side walls of the main body 10 and the cover body 20, which extend into the damping chambers 11 respectively. The damping chambers 11 and the damping grease therein existing on both sides mean that when the cover body 20 rotates, both sides of the cover body 20 are subjected to damping, which not only makes the damping effect more uniform, but also can effectively absorb more impact force, making the opening and closing action smoother and softer, especially for the heavier cover body 20, effectively reducing the impact force generated when the cover body 20 covers the main body 10, further reducing the noise generation, thereby further improving the user experience, and realizing the force balance during the opening and closing process of the cover body 20, which helps to reduce the distortion or deformation caused by uneven force on one side, and improves the stability and durability of the entire structure.

[0044] Specifically, the main body 10 is provided with a cover plate 111 and a surrounding plate 113. The surrounding plate 113 surrounds the connecting piece and is spaced apart from the connecting piece. The surrounding plate 113 and the main body 10 are integrally injection molded. The cover plate 111 covers the surrounding plate 113 to form a damping chamber 11, which effectively prevents external dust, moisture or other contaminants from entering the chamber, protects the damping grease from contamination, extends its service life, and also helps to maintain the consistency of the damping effect. In addition, the setting of the cover plate 111 makes it easier to open the damping chamber 11 for inspection or replacement of the damping grease. Finally, the cover plate 111 is provided with an opening 112 for the connecting piece to pass through.

[0045] The cover plate 111 is provided with a positioning protrusion 1111, and the enclosure plate 113 is provided with a positioning groove 1131 and a threaded hole 1132. The cover plate 111 is first positioned by inserting the positioning protrusion 1111 into the positioning groove 1131, and then the screw 23 is inserted into the threaded hole 1132 to achieve fixed connection with the enclosure plate 113.

[0046] Since the connecting piece is easily damaged due to the pressure of the cover body 20 for a long time, and the existing connecting pieces are all integrated structures, the entire connecting piece can only be replaced. For this reason, in the present embodiment, the connecting piece includes a rotating shaft 12 fixedly connected to the main body 10, a first rotating part 21 located in the damping chamber 11, and a second rotating part 22 located outside the damping chamber 11. The first rotating part 21 is provided with a protrusion 213 that rotates with the opening 112. The first rotating part 21 and the second rotating part 22 are detachably connected. The first rotating part 21 is provided with a rotating shaft hole 211 that cooperates with the rotating shaft 12, so that when maintenance or replacement of parts is required, the operation is simpler and faster. Through the cooperation of the rotating shaft hole 211 and the rotating shaft 12, and the transmission connection between the second rotating part 22 and the cover body 20, flexible docking between the connecting piece and different components is realized, and the compatibility with covers 20 or rotating shafts 12 of different specifications is enhanced, which is convenient to adapt to more diverse application scenarios.

[0047] Specifically, the first rotating part 21 and the second rotating part 22 are connected by a screw 23, and the protrusion 213 and the second rotating part 22 are both provided with a screw hole 214 for the screw 23 to pass through. The first rotating part 21 is also provided with a non-circular limiting hole 215, and the second rotating part 22 is provided with a limiting plate 222, which extends into the limiting hole 215, so that the second rotating part 22 and the first rotating part 21 rotate synchronously.

[0048] Since the resistance of the damping grease to the connecting parts is usually related to the viscosity of the damping grease, the contact area with the connecting parts, etc., in order to make the closing of the cover body 20 smoother, the first rotating part 21 is provided with an impeller 212 extending into the damping chamber 11. The impeller 212 has a large area. When the impeller 212 rotates in the damping chamber 11, it can more effectively stir the damping grease, so that the damping grease is more evenly distributed, providing a more stable and controllable damping force, thereby making the opening and closing action of the cover body 20 smoother.

[0049] Since the viscosity of the damping grease is closely related to temperature, in order to reduce the effect of temperature on the viscosity of the damping grease, the main body 10 is further provided with a heat insulation plate 13 surrounding the enclosure 113, and an insulation gap 14 is provided between the heat insulation plate 13 and the enclosure 113. The setting of the heat insulation plate 13 effectively isolates the influence of the external ambient temperature on the inside of the damping chamber 11, especially for those damping greases that are sensitive to temperature or equipment working in extreme temperature difference environments, it can maintain the stability of the damping performance and avoid the weakening or failure of the damping effect due to temperature fluctuations.

[0050] Of course, you can also replace the damping grease regularly to ensure the damping it provides to the connector.

[0051] Since there are many connection gaps between the various components in this embodiment, in order to reduce the leakage of damping grease, in this embodiment, a sealing ring 15 is provided between the cover plate 111 and the first rotating part 21. After the cover plate 111 is covered on the enclosure 113, the cover plate 111 and the first rotating part 21 are pressed against the sealing ring 15 together. The sealing ring 15 can effectively seal the connection gap between the cover plate 111 and the first rotating part 21, ensuring the sealing of the damping chamber 11. Even in long-term use or at different ambient temperatures, the internal damping grease can be kept stable, thereby extending the service life of the damping system. Of course, sealing rings 15 can also be provided between other components.

[0052] In order to make the opening position of the cover body 20 more reasonable, a limiting rib 16 is provided on the main body 10. The cover body 20 can be rotated relative to the main body 10 to the highest position against the limiting rib 16. The limiting rib 16 provides a clear physical stop point, so that the cover body 20 can accurately stop at the preset highest position during the opening and closing process, ensuring that each opening and closing reaches a consistent height, preventing excessive flipping, and improving the accuracy and reliability of the operation.

[0053] In addition, the cover body 20 is provided with a slot 25, and the second rotating part 22 is provided with a positioning block 221 that is interference-fitted with the slot 25. The interference-fit design of the positioning block 221 and the slot 25 ensures the precise position of the second rotating part 22 on the cover body 20, prevents deviation or shaking during rotation, and improves the accuracy and consistency of the flip action. Secondly, the interference-fit design simplifies the assembly process, and no additional fixing devices such as screws or pins are required. The assembly can be completed by simply inserting the positioning block 221 into the slot 25.

[0054] The cover body 20 includes a covering surface 26 for covering. Since users usually directly grasp the covering surface 26 of the cover body 20, there is a risk of pinching the hand. Therefore, the cover body 20 is provided with a handle 24 that is easy to grasp. The cover body 20 also includes a mounting surface 27 for mounting the handle 24. The staggered design of the covering surface 26 and the mounting surface 27 effectively avoids the risk of pinching the finger or hand when operating the handle 24, especially in the case of fast or strong operation, to ensure the safety of the user. The handle 24 is transmission-connected to the second rotating part 22.

[0055] It can be understood that in other embodiments, a damping chamber is provided on the cover, and an impeller is arranged on the main body. When the cover rotates relative to the main body, the impeller will generate resistance to the damping grease, so that the opening and closing action of the cover becomes smooth and unobtrusive.

[0056] It is understandable that in other embodiments, the cover body can also be automatically closed by its own weight.

[0057] In addition to the above-mentioned preferred embodiments, the present invention also has other implementation modes. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection requested by the present invention.
