DETAILED DESCRIPTION
[0028] The utility model will be described in further detail below in combination with the drawings and examples. It can be understood that the specific examples described herein are only used to explain the utility model, and not limit the utility model.
[0029] In order to make the drawing simple, only the parts related to the utility model are shown in the figures, which do not represent the actual structure of the product. In addition, in order to make the drawing simple and easy to understand, in some figures, only one of the parts with the same structure or function is shown, or only one of them is marked. In this paper, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".
[0030] In this paper, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrated connection; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through intermediate medium, or the communication between two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.
[0031] In the utility model, unless otherwise specified and limited, the first feature "on" or "below" the second feature can include the direct contact between the first and second features, or the contact between the first and second features through another feature between them. Moreover, the first feature "on", "above" and "above" the second feature includes the first feature above and oblique above the second feature, or only indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature "below", "below" and "below" the second feature includes the first feature below and oblique below the second feature, or only indicates that the horizontal height of the first feature is less than that of the second feature.
[0032] In the description of the embodiment, the orientation or position relationship of the terms "up", "down", "left", "right" and the like is based on the orientation or position relationship shown in the drawing, which is only for the convenience of description and simplification of operation, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.
[0033] In addition, in the description of the present application, the terms "first", "second" and the like are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.
[0034] As shown in Figures 1-3 , it shows a current collector hook of the utility model, the hook piece 1 can swing around the connecting point of the seat body 2.When the driving force of the linear driving piece 4 acts, the hook piece 1 swings around the connecting point, realizes the opening or closing action, and is used for hanging or releasing the current collecting rod. The first limiting part 301 and the second limiting part 302 of each set of limiting assembly 3 are respectively located on both sides of the rod part 101 of the hook piece 1. When the hook piece 1 swings, the rod part 101 will abut against the limiting part on the corresponding side. For example, when the hook piece 1 swings to the limit position on one side, the rod part 101 abuts against the first limiting part 301 on the side, limiting its continuous swing; when it swings to the limit position on the other side, it abuts against the second limiting part 302, thereby limiting the swing range of the hook piece 1. Among them, the first limiting part 301 and the second limiting part 302 can be integrated with the seat body 2 or a separate structure, for example, the first limiting part 301 and the second limiting part 302 are a separate structure with the seat body 2, the first limiting part 301 can be a bolt, a latch and the like, and the second limiting part 302 is the same.
[0035] As shown in Figure 6 , the linear driving piece 4 can be a cylinder with two driving ends 401, which provides driving force for the two hook pieces 1 through its linear motion such as extension and contraction. For example, when the linear driving piece 4 contracts, the two driving ends 401 drive the corresponding hook pieces 1 to swing and open on both sides respectively; when the linear driving piece 4 extends, it pushes the hook pieces 1 to swing and close to the middle. Compared with the traditional way of driving each hook by an independent driving structure, the linear driving piece 4 in this scheme is suspended, which will have a small amplitude of up and down movement in the use process, but does not affect the normal use, and one linear driving piece 4 controls two hook pieces 1, reducing the number of driving structures and the occupied space, which is more suitable for the scene where the installation space of the current collector is limited. Reducing the number of driving structures, without the need to equip each hook with an independent driving device, reducing the hardware procurement cost, such as reducing the number of components such as motors and cylinders; at the same time, the later maintenance cost is also reduced due to the reduction of components.
[0036] In some examples, as shown in Figure 4 , Figure 5 and Figure 7As shown, the rod part 101 of the hook part 1 has an abutting part 103 and a swing shaft part 104. The abutting part 103 is at the end of the rod part 101 away from the hook part 102, and is the part that receives the driving force of the linear driving part 4. The swing shaft part 104 is spaced from the abutting part 103 and is located at the position where the abutting part 103 extends to the hook part 102, and is the axis of the swing of the hook part 1. As preferred, the distance between the swing shaft part 104 and the abutting part 103 is short, and the distance between the swing shaft part 104 and the hook part 102 is long, forming a lever-like structure, and the swing shaft part 104 corresponds to the fulcrum of the lever. Through the above design of the lever structure, the linear driving part 4 only needs a short pushing path to realize a large swing of the hook part 102, thereby effectively reducing the range of its own up and down movement, reducing the shaking, shaking and other problems that may be caused by the large movement range of the linear driving part 4, making the whole current collector hook system run more reliably, reducing the probability of failure caused by unstable components, and prolonging the service life of the equipment.
[0037] In some examples, two guide plates 5 are obliquely arranged on the seat body 2 and are respectively located on one side of the two hook parts 1, and the oblique direction is towards the corresponding hook part 1. When the current collecting rod is lowered, the guide plate 5 uses its inclined surface to guide the current collecting rod. Due to the inclination of the guide plate 5, the current collecting rod will gradually move below the hook part 102 of the hook part 1 along the inclined direction of the guide plate 5 after contacting the guide plate 5 under the action of gravity. When the hook part 1 swings, the hook part 102 will approach or move away from the guide plate 5. When the hook part 1 swings open, the hook part 102 moves away from the guide plate 5, leaving enough space for the current collecting rod to enter below the hook part 102 along the guide plate 5; when the hook part 1 swings to close and hang the current collecting rod, the hook part 102 approaches the guide plate 5, completing the hanging operation of the current collecting rod. The guiding effect of the guide plate 5 makes the movement trajectory of the current collecting rod in the lowering process more controllable, reducing the risk of failure caused by the deviation or shaking of the current collecting rod.
[0038] In some examples, the first limiting part 301 is arranged to move relative to the seat body 2, that is, there is a movable connection between the first limiting part 301 and the seat body 2, such as threaded connection of a bolt, latch, etc. When the first limiting part 301 approaches the second limiting part 302, the interval between the two is reduced. Since the first limiting part 301 and the second limiting part 302 are respectively located on both sides of the rod part 101 of the hook part 1, the reduction of the interval will limit the swing range of the hook part 1 and improve the adaptability.
[0039] In some examples, the connecting piece 6 and the abutting part 103 are connected in rotation, and a relative rotation structure is formed between the two. The abutting part 103 is guaranteed to follow the movement of the connecting piece 6, and movement interference caused by rigid connection is avoided. The U-shaped connecting piece 6 is in abutment with the two ends of the abutting part 103 perpendicular to the swinging direction in structure. On the one hand, stable force transmission is ensured, and the abutting part 103 can be effectively driven to move; on the other hand, the U-shaped structure provides space for the abutting of the abutting part 103 and the first limiting part 301 or the second limiting part 302. When the hook piece 1 swings to the limit position, the abutting part 103 can be in contact with the first limiting part 301 or the second limiting part 302 to limit the swinging range, and the U-shaped connecting piece 6 does not hinder this process.
[0040] As shown in Figure 6 , the driving end 401 of the linear driving piece 4 is connected with the connecting piece 6 through screw connection. The overall length of the connecting piece 6 and the driving end 401 can be adjusted by rotating the connecting piece 6, and the screw connection makes the overall structure convenient to disassemble and maintain.
[0041] In some examples, the provision of the notched groove 201 improves space utilization and makes the overall structure more compact.
[0042] In some examples, the shock-absorbing strip 7 is installed on the seat body 2 and below the hook part 102. When the current collector rod reaches a predetermined position during the lowering or other actions, it will first contact the shock-absorbing strip 7. Since the shock-absorbing strip 7 has a certain elasticity and buffering performance, it can absorb the impact force when the current collector rod falls, avoiding the direct impact of the current collector rod on the iron part of the current collector hook. Preventing the direct contact between the current collector rod and the iron part of the current collector hook avoids the wear, deformation, and even damage caused by the rigid collision between the two. The current collector rod and the iron part of the current collector hook are important components of the current collector, and their normal working state directly affects the stability of power transmission. Through the buffering effect of the shock-absorbing strip 7, the service life of the current collector rod and the iron part of the current collector hook is prolonged, and the maintenance and replacement cost of the equipment is reduced.
[0043] In some examples, as shown in Figure 3 and Figure 4 , two shock-absorbing strips 7 are provided at the position of each hook piece 1. The shock-absorbing strip 7 is preferably made of rubber material and has a certain height, preferably higher than the thickness of the bolt head, which can provide space for fixing other parts on the seat body 2 and does not hinder the bearing of the current collector rod.
[0044] It should be noted that the above examples are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the present application, and all should be covered in the scope of the claims of the present application.
