Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and more specifically, to an unlocking component for a storage mechanism. Background Technology

[0002] Vehicles typically have storage compartments in areas such as the dashboard or center console. These compartments include a storage box and a cover that fits over the box. The cover is equipped with a locking mechanism to lock it onto the box. Furthermore, the cover has an unlocking handle connected to the locking mechanism. By turning the unlocking handle on the cover, occupants can unlock the cover, allowing it to rotate relative to the box to an open position.

[0003] The surface of the unlocking handle has a raised structure, and the cover has a corresponding stop structure. The stop structure stops the raised structure during the rotation of the unlocking handle, thereby limiting the rotation stroke of the unlocking handle.

[0004] Currently, the unlocking handles of vehicle storage mechanisms on the market typically have protruding structures that are exposed in the angled space where passengers' fingers can reach, encroaching on the operating space of passengers' fingers, and easily causing discomfort to the fingers or even cutting them, resulting in a poor user experience.

[0055] Example

[0056] Please refer to the following: Figure 1 and Figure 2 , Figure 1 The diagram shown is a structural schematic of the unlocking component 100 of the storage mechanism 200 provided in this embodiment in one state during actual application. Figure 2 The diagram shows the structure of the unlocking component 100 in another state in actual application.

[0057] Vehicles typically have storage mechanisms 200 located in areas such as the dashboard or center console. These storage mechanisms include a housing and a cover that fits over the housing. The unlocking component 100 provided in this embodiment is applied to the storage mechanism 200 and can rotate relative to the storage mechanism 200 under external force to unlock the storage mechanism 200, allowing the cover of the storage mechanism 200 to rotate relative to the housing to an open state. Figure 1 The image shows the unlocking component 100 installed on the cover of the storage mechanism 200 and in its pre-unlocked state. Figure 2 The image shows the state of the unlocking component 100 after it has been unlocked.

[0058] Please refer to the following: Figure 3 and Figure 4 , Figure 3 The diagram shown is a partial structural schematic of the unlocking component 100. Figure 4 As shown Figure 3 An exploded view of the structure shown.

[0059] In this embodiment, the unlocking component 100 includes a base 110, an unlocking handle 120, and a locking component. The base 110 is disposed on the storage mechanism 200, and the unlocking handle 120 is located on the base 110 and rotatably connected to the locking component. The unlocking handle 120 is configured to rotate between a locked state and an unlocked state when force is applied, so as to selectively unlock the storage mechanism 200 through the locking component, thereby allowing the cover of the storage mechanism 200 to be opened.

[0060] With the storage mechanism 200 locked, the unlocking handle 120 is in the locked position. Figure 1 The locking state is shown, with the locking component engaging with the housing. When it is necessary to unlock the storage mechanism 200, a force is applied to the unlocking handle 120, causing the unlocking handle 120 to rotate from the locked state to the unlocked state. Figure 2 The unlocked state shown causes the locking component to disengage from the housing, thus unlocking the cover.

[0061] Please refer to the following: Figure 5 , Figure 5 The diagram shows the connection structure between the unlocking handle 120 and the locking assembly.

[0062] In this embodiment, the locking assembly includes a rotating cylinder 150 and a locking rod 160. The rotating cylinder 150 is slidably disposed on the base 110, and the unlocking handle 120 is rotatably sleeved on the rotating cylinder 150. One end of the locking rod 160 is connected to the rotating cylinder 150, and the other end is selectively engaged with the housing.

[0063] In practical applications, a mating structure is provided between the unlocking handle 120 and the rotating cylinder 150, so that when the unlocking handle 120 rotates around the rotating cylinder 150, the mating structure can drive the rotating cylinder 150 to slide on the base 110. During the sliding process of the rotating cylinder 150, the locking rod 160 moves synchronously until it disengages from the box body, thereby completing the unlocking of the cover.

[0064] The specific mating structure can be selected according to the actual application conditions, and no restrictions are imposed in this application. For example, a cam groove inclined relative to its axis can be recessed on the outer wall of the rotating cylinder 150, and a slider embedded in the cam groove can be provided on the unlocking handle 120. When the unlocking handle 120 is subjected to force and rotates around the rotating cylinder 150, it drives the slider to slide along the groove wall of the cam groove, thereby driving the rotating cylinder 150 to slide on the base 110.

[0065] A compression spring can also be installed between the rotating drum 150 and the unlocking handle 120. As the occupant moves the unlocking handle 120 from the locked state to the unlocked state to unlock the storage mechanism 200, the compression spring is gradually compressed. After the cover is opened, the occupant releases the unlocking handle 120, and the compression spring releases its elastic potential energy, pushing the rotating drum 150 to its reset sliding position. During the reset sliding process of the rotating drum 150, the pushing force of the cam groove wall on the slider drives the unlocking handle 120 to complete its reset, i.e., rotate to the locked state.

[0066] To limit the rotational travel of the unlocking handle 120, one of the base 110 and the unlocking handle 120 has a receiving groove 111, and the other has a limiting protrusion 121 that is embedded in and movably engages with the receiving groove 111. At least one end of the receiving groove 111 has a stop portion for stopping the limiting protrusion 121. In other words, if the receiving groove 111 is provided on the base 110, the limiting protrusion 121 can be provided on the unlocking handle 120; if the limiting protrusion 121 is provided on the base 110, the receiving groove 111 can be provided on the unlocking handle 120.

[0067] During the rotation of the unlock handle 120 between the locked and unlocked states, the limiting protrusion 121 moves within the receiving groove 111. The receiving groove 111 guides and stores the limiting protrusion 121, preventing it from being exposed. This prevents the space for the occupant to operate the unlock handle 120 from being encroached upon by the limiting protrusion 121, and avoids the occupant touching the limiting protrusion 121 and experiencing discomfort or even injury.

[0068] Therefore, the unlocking component 100 of the storage mechanism 200 provided in this embodiment can improve the utilization rate of the unlocking operation space, the comfort of use and the safety of use, resulting in a better user experience.

[0069] Please refer to the following: Figure 6 , Figure 6 The diagram shown is a structural schematic of the unlocking handle 120.

[0070] In this embodiment, the unlocking handle 120 has a handle portion 122 and a sleeve portion 123. The sleeve portion 123 is rotatably mounted on the base 110. The handle portion 122 is connected to the sleeve portion 123 and is used to drive the sleeve portion 123 to rotate under force. A receiving groove 111 is formed on one of the sleeve portion 123 and the base 110, and a limiting protrusion 121 is provided on the other one.

[0071] In fact, the sleeve part 123 is coaxially sleeved on the outer wall of the rotating cylinder 150. When the occupant applies force to pull the handle part 122, it can drive the sleeve part 123 to rotate around the rotating cylinder 150. Under the action of the sleeve part 123, the rotating cylinder 150 slides on the base 110, thereby driving the locking rod 160 to move to complete the unlocking.

[0072] To ensure a stable locked state and a smooth unlocking process for the storage mechanism 200, this embodiment uses two sleeve portions 123, coaxially arranged on the handle portion 122. There are also two rotating cylinders 150 and two locking rods 160. The two rotating cylinders 150 are inserted into the opposite ends of the two sleeve portions 123, and the two locking rods 160 are connected to the two rotating cylinders 150 respectively. In practical application, when the occupant applies force to rotate the handle portion 122, the two sleeve portions 123 move closer together, thereby disengaging their respective locking rods 160 from the housing.

[0073] The two opposite ends of the two sleeve portions 123 are defined as axial end faces 1231. The base 110 has limiting end walls 113 opposite to the two axial end faces 1231, that is, the sleeve portions 123 are located between the two limiting end walls 113. Guide holes are provided through the two limiting end walls 113, and the two rotating cylinders 150 are slidably inserted into the two guide holes respectively.

[0074] To ensure stable sliding of the two rotating cylinders 150, in this embodiment, both guide holes are rectangular holes, and correspondingly, the portions of the two rotating cylinders 150 that pass through the two guide holes are rectangular. Specifically, the rotating cylinder 150 includes a cylindrical section and a rectangular section coaxially connected. The cylindrical section is located inside the limiting end wall 113, that is, on the side close to the sleeve portion 123. The rectangular section passes through the guide hole, and the sleeve portion 123 is fitted onto the outer surface of the cylindrical section. A stepped surface with an area larger than the guide hole is formed between the cylindrical section and the rectangular section to prevent the cylindrical section from entering the guide hole.

[0075] The sleeve portion 123 also has a circumferential convex arc surface 1232, the base 110 has a concave arc surface 114 that matches the circumferential convex arc surface 1232, the receiving groove 111 is formed on one of the circumferential convex arc surface 1232 and the concave arc surface 114, and the limiting protrusion 121 protrudes on the other of the two.

[0076] The concave arc surface 114 on the base 110 matches the circumferential convex arc surface 1232 of the sleeve portion 123, meaning that their curvatures are approximately the same. This allows the gap between the sleeve portion 123 and the base 110 to be kept as small as possible. On the one hand, this makes the overall structure of the unlocking component 100 more compact, and on the other hand, it prevents the occupant from inserting their fingers into the gap between the sleeve portion 123 and the base 110 when performing the unlocking operation, thus improving user comfort and safety.

[0077] In this embodiment, the receiving groove 111 is formed on the concave arc surface 114, and the limiting protrusion 121 protrudes from the circumferential convex arc surface 1232. In another embodiment, the receiving groove 111 may be formed on the circumferential convex arc surface 1232 of the sleeve portion 123, and the corresponding limiting protrusion 121 may be formed on the concave arc surface 114 of the base 110.

[0078] To improve the stability of the unlocking handle 120, in this embodiment, there are two limiting protrusions 121 and two receiving grooves 111. The two limiting protrusions 121 are spaced apart in the extension direction of the rotation center line of the unlocking handle 120 and are respectively embedded in the two receiving grooves 111.

[0079] Specifically, two limiting protrusions 121 are respectively provided on the circumferential convex arc surfaces 1232 of the two sleeve portions 123, and are located near the two opposite ends of the two sleeve portions 123. Correspondingly, two receiving grooves 111 are respectively formed on the concave arc surface 114 near the two limiting end walls 113.

[0080] In another embodiment, the receiving groove 111 can be formed on one of the axial end face 1231 and the limiting end wall 113, and the limiting protrusion 121 can be formed on the other one. For example, the receiving groove 111 can be formed on the side of the limiting end wall 113 of the base 110 near the sleeve portion 123, with its extension trajectory being circular and the center of the circle being on the axis of the sleeve portion 123, and the limiting protrusion 121 can be formed on the axial end face 1231 of the sleeve portion 123.

[0081] Furthermore, in this case, a receiving groove 111 can be opened on each of the two limiting end walls 113, and a limiting protrusion 121 can be protruded on the axial end face 1231 of the two sleeve portions 123, with the two limiting protrusions 121 respectively embedded in the two receiving grooves 111.

[0082] Conversely, the receiving groove 111 can be opened on the two axial end faces 1231, and the limiting protrusions 121 can be correspondingly provided on the two limiting end walls 113.

[0083] Please refer to the following: Figure 7 and Figure 8 , Figure 7 The diagram shows the structure of the unlocking component 100 when the unlocking handle 120 is in the unlocked state. Figure 8 The diagram shows the structure of the unlocking component 100 when the unlocking handle 120 is in the locked state.

[0084] To further improve the space utilization of the occupant unlocking operation, in this embodiment, the outer wall of the sleeve portion 123 also has a smooth handle guide surface 1233, and the handle portion 122 protrudes from the handle guide surface 1233, forming an angled space 130 with the handle guide surface 1233 for fingers to insert. In the direction in which the unlocking handle 120 rotates to the unlocked state, the handle guide surface 1233 is located between the limiting protrusion 121 and the handle portion 122.

[0085] It is understood that the handle guide surface 1233 on the outer wall of the sleeve portion 123 can be a part of the circumferential convex arc surface 1232, or it can be a smooth surface on the outer wall of the sleeve portion 123 with a curvature different from that of the circumferential convex arc surface 1232. In this embodiment, the smoothness of the handle guide surface 1233 means that the surface of the handle guide surface 1233 is flat and does not have abrupt structures, that is, there are no reinforcing ribs or openings.

[0086] Please refer to the following: Figure 9 , Figure 9 The diagram shown is a structural schematic of the occupant's lever handle 122.

[0087] The handle guide surface 1233 can guide the occupant to pull the handle part 122. For example, when the occupant inserts his / her finger into the angle space 130 formed by the handle guide surface 1233 and the handle part 122, if the occupant's finger touches the handle guide surface 1233, he / she can touch and pull the handle part 122 under the guidance of the handle guide surface 1233.

[0088] Because the handle guide surface 1233 is smooth, it can improve the utilization rate of the angle space 130 and avoid the presence of surface protrusions that would encroach on the occupant's finger operation space. On the other hand, it can also prevent the user's fingers from touching protrusions or depressions, which can further improve the comfort and safety of use.

[0089] Furthermore, in this embodiment, to further enhance the user experience, the side of the handle 122 that participates in defining the angled space 130 is also a smooth surface. Moreover, to prevent occupants from touching the two ends of the handle 122 along the axial extension direction of the sleeve portion 123 when their fingers are inserted into the angled space 130, thus avoiding discomfort or even finger injuries, in this embodiment, the two ends of the handle 122 protrude beyond the two ends of the sleeve portion 123 along the axial extension direction, and the edges of the two ends of the handle 122 are rounded to form a smooth arc surface.

[0090] Please refer to the following: Figures 10 to 13 , Figure 10 As shown Figure 7 Sectional view of section AA. Figure 11 As shown Figure 10 Enlarged diagram of region A in the middle. Figure 12 As shown Figure 8 Sectional view of section BB. Figure 13 As shown Figure 12 Enlarged schematic diagram of region B in the middle.

[0091] In this embodiment, in the direction in which the unlocking handle 120 rotates to the unlocked state, a first stop 112 is provided at the end of the receiving groove 111 away from the handle portion 122. A first limiting surface is provided on the side of the first stop 112 near the receiving groove 111. In the locked state of the unlocking handle 120, the first limiting surface of the first stop 112 contacts the limiting protrusion 121.

[0092] The unlocking handle 120 also has a limiting part 124. In the rotation direction of the unlocking handle 120, the limiting part 124 and the limiting protrusion 121 are respectively located on opposite sides of the first stop part 112. The first stop part 112 is provided with a second limiting surface on the side away from the receiving groove 111. In the unlocked state, the second limiting surface of the first stop part 112 contacts the limiting part 124 to limit the rotation stroke of the unlocking handle 120.

[0093] The direction in which the unlock handle 120 is turned toward the unlocked position is... Figure 10 In the direction indicated by the W arrow, the handle guide surface 1233 is located between the limiting protrusion 121 and the handle portion 122. In the rotation direction of the unlocking handle 120, the limiting portion 124 and the limiting protrusion 121 are located on opposite sides of the first stop portion 112, that is, the limiting portion 124 and the handle portion 122 are located on opposite sides of the limiting protrusion 121.

[0094] In other words, the limiting part 124 is also outside the angled space 130 where the occupant's fingers can be inserted to operate the handle part 122. The limiting part 124 does not encroach on the operating space and will not be touched by fingers during the unlocking process.

[0095] Understandably, the limiting part 124 protrudes from the circumferential convex arc surface 1232 of the sleeve part 123, ensuring that when the unlocking handle 120 is rotated to the unlocked state, the first stop part 112 can contact the limiting part 124 to prevent the unlocking handle 120 from rotating excessively.

[0096] In practical applications, when the storage mechanism 200 is locked, the unlocking handle 120 is in the following position: Figure 8 In the locked state shown, the two locking levers 160 engage with the housing, and the first limiting surface of the first stop 112 contacts the side of the limiting protrusion 121 away from the handle 122. When it is necessary to unlock the storage mechanism 200, the occupant inserts their finger into the angled space 130 and pulls the handle 122. The handle 122 drives the sleeve 123 to rotate around the rotating cylinder 150 in the direction indicated by the W arrow. During this process, the limiting protrusion 121 gradually moves away from the first stop 112 after disengaging from the first limiting surface of the first stop 112, while the limiting part 124 gradually approaches the second limiting surface of the first stop 112.

[0097] When the sleeve portion 123 rotates to the point where the limiting portion 124 contacts the second limiting surface of the first stop portion 112, the sleeve portion 123 stops rotating under the stop of the first stop portion 112, and the unlocking handle 120 is in the position as follows. Figure 7 The unlocked state is shown. In this state, the limiting protrusion 121 is still inside the receiving groove 111.

[0098] In this embodiment, when the unlocked state of the unlock handle 120, the end of the receiving groove 111 near the handle portion 122 is closed to prevent the occupant's fingers from getting stuck in the receiving groove 111 when they are inserted into the angled space 130, thereby further improving the comfort and safety of use.

[0099] It is understandable that when the operating handle is rotated from the locked state to the unlocked state, the limiting part 124 will collide with the first stop part 112. Similarly, when the operating handle is rotated from the unlocked state to the locked state, the limiting protrusion 121 will also collide with the first stop part 112. In order to avoid the impact causing the unlocking handle 120 to rebound and generate noise, in this embodiment, a buffer 140 is provided on the surface of the first stop part 112.

[0100] Please refer to the following: Figure 14 and Figure 15 , Figure 14 This is a schematic diagram of the structure of the buffer 140 mounted on the base 110. Figure 15 for Figure 14 A magnified view of region C in the middle.

[0101] In this embodiment, the buffer member 140 is adhered to the surface of the first stop portion 112. To prevent the buffer member 140 from lifting off the surface of the first stop portion 112 and causing the buffering effect to fail, the buffer member 140 extends from the first limiting surface of the first stop portion 112 to the other side surface that forms an angle with the first limiting surface. Similarly, the buffer member 140 also extends from the second limiting surface of the first stop portion 112 to the other side surface that forms an angle with the second limiting surface.

[0102] Preferably, in this embodiment, the buffer 140 is felt, which is attached to the surface of the first stop portion 112 in a "U" shape. In other embodiments, rubber, sponge, or the like can also be used as the buffer 140. In another embodiment, the buffer 140 can also be provided on the surfaces of the limiting protrusion 121 and the limiting portion 124, which can also achieve the effect of buffering impact.

[0103] Please see Figure 16 , Figure 17 and Figure 18 , Figure 16 The diagram shown is a structural schematic of the unlocking component 100 of the storage mechanism 200 in another embodiment when the unlocking handle 120 is in the unlocked state. Figure 17 As shown Figure 16 Sectional view of section C-C. Figure 18 The figure shown is a cross-sectional view of the unlocking component 100 in this embodiment when the unlocking handle 120 is in the locked state.

[0104] In this embodiment, a second stop 115 is provided at one end of the receiving groove 111 near the handle portion 122. When the unlocking handle 120 is in the unlocked state, the limiting protrusion 121 contacts the second stop 115 to limit the rotation stroke of the unlocking handle 120.

[0105] Specifically, when the storage mechanism 200 is locked, the unlocking handle 120 is in the locked state. At this time, the two locking rods 160 cooperate with the box body, and the limiting protrusion 121 contacts the first stop 112 provided at the end of the receiving groove 111 away from the handle 122. Figure 18 As shown. When it is necessary to unlock the storage mechanism 200, the occupant inserts his finger into the angled space 130 and pulls the handle 122. The handle 122 drives the sleeve 123 to rotate around the rotating cylinder 150. During this process, the limiting protrusion 121 disengages from the first stop 112 away from the handle 122 and gradually moves towards the second stop 115 closer to the handle 122.

[0106] When the sleeve portion 123 rotates until the limiting protrusion 121 contacts the second stop portion 115, the sleeve portion 123 stops rotating under the stop of the second stop portion 115, and the unlocking handle 120 is in the position as follows. Figure 16 The unlocked state is shown. It can be understood that the first stop 112 and the second stop 115 also serve to seal both ends of the receiving groove 111, on the one hand to prevent external substances from entering the receiving groove 111 and affecting the smooth movement of the limiting protrusion 121, and on the other hand to prevent the user's finger from getting stuck in the receiving groove 111.

[0107] In this embodiment, a buffer 140 is provided on the surface of the limiting protrusion 121 to buffer the impact between the limiting protrusion 121 and the first stop 112 and the second stop 115. In another embodiment, the buffer 140 may also be provided on the surfaces of the first stop 112 and the second stop 115.

[0108] In summary, the unlocking component 100 of the storage mechanism 200 provided in this application can improve the utilization rate of the unlocking operation space, the comfort of use, and the security of use, resulting in a better user experience.
