DETAILED DESCRIPTION

[0032] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0033] See also: Figure 1 , Figure 2 , Figures 5 to 7 As shown, the present invention provides a handle structure, which includes: a handle body 10, the handle body 10 including a lifting part 11 and at least one fixed mounting part 12, the fixed mounting part 12 being connected to the end of the lifting part 11, at least one end of the fixed mounting part 12 protruding from the handle body 10 along a first direction by a predetermined length, and both the portion of the fixed mounting part 12 protruding from the handle body 10 and the portion of the fixed mounting part 12 not protruding from the handle body 10 are provided with at least one first connecting structure 13.

[0034] In this embodiment, the first direction refers to Figure 1 The width of the lifting section 11. The handle structure is installed on the side of the object to be lifted (such as an energy storage battery box) and is fixedly connected to the object by bolts. When the object needs to be lifted, the worker holds the lifting section 11 and lifts the object upward to move it to a preset position. At this time, the hand applies a force to the force point on the lifting section 11. Since the weight of the object to be lifted is constant, the lifting force on the force point on the lifting section 11 is fixed and equal to the weight of the object to be lifted. The first connecting structure 13 is used to pass through bolts to realize the fixed connection between the handle structure and the object to be lifted. The position of the first connecting structure 13 is the fixing point of the handle structure. This application increases the lever arm length from the fixing point of the handle body 10 to the force point on the handle body 10 by having at least one end of the fixing part 12 protrude beyond the handle body 10 by a predetermined length in the first direction. According to the definition of torque, torque is equal to the product of force and lever arm. Therefore, after increasing the lever arm length, under the same lifting force (the torque at the force point remains unchanged), the force on the fixing point of the handle structure will be smaller, which is equivalent to increasing the deformation resistance at the fixing point. This can reduce the deformation of the handle structure during the lifting process, reduce the probability of deformation and damage to the handle body 10, and improve the service life of the handle structure.

[0035] In one embodiment of the present invention, there is one fixed mounting part 12. Along the second direction, the lifting part 11 has a first end and a second end that are disposed opposite to each other, and the fixed mounting part 12 is connected to the first end of the lifting part 11.

[0036] In this embodiment, the second direction refers to Figure 6The length direction of the pulling part 11. When lifting the object to be lifted, the force is mainly applied to the first end of the pulling part 11, and since at least one end of the fixed mounting part 12 protrudes from the handle body 10 by a predetermined length in the first direction, the force arm of the handle body 10 can be increased, the deformation of the handle structure during lifting can be reduced, and the service life of the handle structure is improved. Since the fixed mounting part 12 is only one, the installation process becomes simpler, and only needs to be fixed on one side of the object to be lifted, which reduces the installation time, and setting the fixed mounting part 12 on only one end of the pulling part 11 can save materials and reduce costs.

[0037] As shown in Figure 6 An embodiment of the utility model, the handle body 10 still includes connecting part 14, connecting part 14 is connected in the second end of pulling part 11, along the second direction, connecting part 14 is located in the projection range of pulling part 11.

[0038] Through the above-mentioned setting, the connection stability of the handle body 10 can be guaranteed.

[0039] Combined with the Figures 1 to 6 An embodiment of the utility model, the end of the fixed mounting part 12 away from the stress direction of the pulling part 11 protrudes from the handle body 10 by a predetermined length in the first direction.

[0040] In the embodiment, when lifting the object to be lifted, the stress direction of the pulling part 11 is downward, the end of the fixed mounting part 12 away from the stress direction of the pulling part 11, that is, upward, protrudes from the handle body 10 by a predetermined length in the first direction, and when lifting upward, the torsional force received by the pulling part 11 is mainly concentrated below the fixed mounting part 12. The above-mentioned setting mode can more accurately enhance the torsion resistance.

[0041] As shown in Figure 13 And Figure 14 An embodiment of the utility model, both ends of the fixed mounting part 12 protrude from the handle body 10 by a predetermined length in the first direction.

[0042] Through the above-mentioned setting, more lifting directions can be adapted, and the torsion resistance of the handle structure is further enhanced.

[0043] It should be emphasized that the predetermined length referred to in the embodiment can be one-third, one-half or one time of the height of the pulling part 11 in the first direction.

[0044] An embodiment of the utility model, the fixed mounting part 12 is provided with a first pre-installation structure, and the first pre-installation structure includes one or more of a through hole 15, a clamping groove and a protruding structure.

[0045] Through the above arrangement, on the one hand, the connection process of the handle structure and the object to be lifted can be simplified, and the user or the assembly worker does not need additional operations to align or fix during installation, thereby improving the installation efficiency, and on the other hand, through the precise matching of the first pre-installation structure, installation errors can be significantly reduced, and product damage caused by improper installation can be avoided.

[0046] Specifically, the through hole 15 on the fixed mounting portion 12 can cooperate with the positioning pin, positioning column, protrusion, etc. on the object to be lifted to realize installation positioning, simplify the installation process, and reduce the installation time. The clamping slot on the fixed mounting portion 12 can cooperate with the protrusion on the object to be lifted to realize installation positioning. The protrusion structure on the fixed mounting portion 12 can cooperate with the groove on the object to be lifted to realize preliminary installation positioning, thereby facilitating subsequent fixing operations.

[0047] As shown in Figure 1 In an embodiment of the utility model, the lifting portion 11 has a lifting slot 114, and the bottom of the lifting portion 11 is provided with an arc-shaped flange 115, one end of the arc-shaped flange 115 is connected with the bottom of the lifting portion 11, and the other end of the arc-shaped flange 115 extends to the top of the handle body 10.

[0048] In the embodiment, the lifting slot 114 provides a space for natural bending of fingers or palms, so that the user can hold the handle body 10 more comfortably when lifting. The design of the arc-shaped flange 115 reduces sharp edges and corners, thereby reducing the risk of injury that may occur during use, especially when lifting objects. This design can effectively avoid direct contact between the hand and the edge, thereby improving the safety of use.

[0049] It should be noted that the other end of the arc-shaped flange 115 can be bent to the side where the lifting slot 114 is located and extend to the top of the handle body 10, or the other end of the arc-shaped flange 115 can also be bent away from the side where the lifting slot 114 is located and extend to the top of the handle body 10. In addition, the arc-shaped flange 115 extends in the second direction, and the part of the arc-shaped flange 115 that contacts the hand is arc-shaped, which can prevent the hand from being scratched.

[0050] In an embodiment of the utility model, when the part of the fixed mounting portion 12 protruding from the handle body 10 is located at the top of the handle body 10, the number of first connection structures 13 on the part of the fixed mounting portion 12 not protruding from the handle body 10 is greater than or equal to the number of first connection structures 13 on the part of the fixed mounting portion 12 protruding from the handle body 10.

[0051] In the embodiment, when the part of the fixed mounting portion 12 protruding from the handle body 10 is located at the top of the handle body 10, the force is mainly applied to the part of the fixed mounting portion 12 protruding from the handle body 10 when the handle body 10 is pulled upward, at this time, by increasing the number of the first connecting structures 13 of the part not protruding, on the one hand, the fixing points between the bottom of the handle body 10 and the object to be lifted can be significantly increased, thereby improving the anti-twisting performance of the handle structure, preventing the handle body 10 from being twisted or damaged when being pulled, on the other hand, it is helpful to balance the moment generated when the part of the fixed mounting portion 12 protruding from the handle body 10 is stressed, so that the force distribution of the handle body 10 when bearing external force is more uniform, stress concentration is reduced, and the stability and safety of the overall structure are improved.

[0052] In an embodiment of the utility model, when the part of the fixed mounting portion 12 protruding from the handle body 10 is located at the bottom of the handle body 10, the number of the first connecting structures 13 on the part of the fixed mounting portion 12 not protruding from the handle body 10 is less than or equal to the number of the first connecting structures 13 on the part of the fixed mounting portion 12 protruding from the handle body 10.

[0053] In the embodiment, when the part of the fixed mounting portion 12 protruding from the handle body 10 is located at the bottom of the handle body 10, since the pulling portion 11 mainly bears the force perpendicular to the direction of the handle body 10 when the handle body 10 is pulled upward, at this time, the number of the first connecting structures 13 on the part of the fixed mounting portion 12 protruding from the handle body 10 is greater than or equal to the number of the first connecting structures 13 on the part of the fixed mounting portion 12 not protruding from the handle body 10, when installing, the bottom of the handle body 10 can be connected to the object to be lifted through more first connecting structures 13, the pulling force can be more evenly dispersed, stress concentration is reduced, and the stability of the handle structure is improved, at the same time, when being pulled upward, the handle body 10 is easily affected by the twisting force, through the above setting, the contact area with the object to be lifted can be increased, a more stable fixing point is formed, thereby the anti-twisting performance is significantly improved, and unnecessary twisting or damage of the handle structure during use is prevented.

[0054] In an embodiment, the first connecting structure 13 can be a connecting hole.

[0055] As Figure 1 and Figure 2As shown, in one embodiment of the present invention, there are two fixing installation parts 12, and the lifting part 11 includes a first plate segment 111, a second plate segment 112, and a third plate segment 113 connected in sequence. The second plate segment 112 is bent relative to the first plate segment 111, and the third plate segment 113 is bent relative to the second plate segment 112. The three are bent to form a U-shaped structure. One fixing installation part 12 is located on the side of the first plate segment 111 facing or away from the third plate segment 113, and is connected to the end of the first plate segment 111 away from the second plate segment 112. The other fixing installation part 12 is located on the side of the third plate segment 113 facing or away from the first plate segment 111, and is connected to the end of the third plate segment 113 away from the second plate segment 112.

[0056] In this embodiment, the U-shaped structure design provides a more ergonomic grip experience. When the hand grips the lifting part 11, the curvature of the hand naturally conforms to the U-shaped structure, thus providing better grip and comfort. The U-shaped design also allows the handle structure to better resist torsion when subjected to external forces.

[0057] In one embodiment of the present invention, the portion of the fixed mounting part 12 protruding from the handle body 10 extends at a preset angle along the second direction toward or away from the lifting part 11, and the preset angle ranges from 0° to 45°.

[0058] In this embodiment, when the handle body 10 is pulled up, the portion of the fixed mounting part 12 tilted at a preset angle can increase the lever arm of the contact between the handle body 10 and the object to be lifted, making the handle body 10 more stable when subjected to lateral or perpendicular forces, and reducing the probability of the handle body 10 being twisted or deformed.

[0059] See also Figure 3 , Figures 8 to 10 As shown, according to another aspect of the present invention, an energy storage battery box is also provided, comprising: the handle structure described above; a box body 20, wherein the handle structure is mounted on the lifting side of the box body 20 via a fixed mounting part 12.

[0060] In this embodiment, the energy storage battery box also includes a battery module for storing electrical energy, which is installed inside the box body 20. When the energy storage battery box needs to be moved, the operator holds the lifting part 11 to lift the energy storage battery box. The handle structure of the energy storage battery box has all the technical solutions and effects of the handle structure described above, and will not be repeated here.

[0061] In one embodiment of this utility model, a plurality of second connecting structures are provided on the housing 20, and the plurality of second connecting structures are provided in a one-to-one correspondence with a plurality of first connecting structures 13.

[0062] In the embodiment, the plurality of second connecting structures are arranged in one-to-one correspondence with the plurality of first connecting structures 13, and during installation, the bolts are sequentially threaded through the first connecting structures 13 and the second connecting structures to fixedly install the handle structure on the box body 20.

[0063] In an embodiment of the utility model, the pulling side surface of the box body is provided with a second pre-installation structure, and the second pre-installation structure cooperates with the first pre-installation structure to position the handle structure.

[0064] Through the above arrangement, the installation and positioning of the handle structure can be realized.

[0065] In an embodiment of the utility model, when the first pre-installation structure is arranged on the fixed installation part 12, and the first pre-installation structure comprises the through hole 15, the second pre-installation structure arranged on the box body 20 is a first positioning hole, and the first positioning hole is arranged in correspondence with the through hole 15. When the first pre-installation structure is arranged on the fixed installation part 12, and the first pre-installation structure comprises the clamping groove, the second pre-installation structure arranged on the box body 20 is the positioning protrusion 21, the clamping groove is arranged in correspondence with the positioning protrusion 21, and the positioning protrusion 21 can be clamped in the clamping groove. When the first pre-installation structure is arranged on the fixed installation part 12, and the first pre-installation structure comprises the protruding structure, the second pre-installation structure arranged on the box body 20 is a second positioning hole, the second positioning hole is arranged in correspondence with the protruding structure, and the protruding structure can be clamped in the second positioning hole.

[0066] Through the above arrangement, on the one hand, the handle structure can be quickly and accurately positioned at the correct position on the box body 20, without the need for additional measurement or adjustment, greatly simplifying the installation process and improving the installation efficiency; on the other hand, the accuracy of the handle structure during installation can be ensured, and the product quality can be guaranteed. In addition, the first pre-installation structure cooperates with the second pre-installation structure on the box body 20 to form a foolproof (anti-misinstallation) mechanism, ensuring that the handle structure can only be installed in the correct direction and position, avoiding installation errors.

[0067] It should be noted that the first pre-installation structure is arranged on at least one fixed installation part 12.

[0068] In an embodiment, the first pre-installation structure can also be arranged on the connecting part 14, and the first pre-installation structure is located on the surface of the connecting part 14 that faces the box body 20 and contacts the box body 20.

[0069] As Figure 11The structure diagram of a handle in the prior art, i.e., handle 22, is shown in Figure 1. The two ends of the handle 22 are fixed and installed by a single bolt. Assuming that the force applied by the staff to the handle 22 is F, and the length of the handle 22 is L, the force arm is 1 / 2L, and the moment of force at the fixed point of the handle 22 is M = 1 / 4FL.

[0070] As shown in Figure 1, the structure diagram of a handle in the prior art, i.e., handle 22, is shown in Figure 1. The two ends of the handle 22 are fixed and installed by a single bolt. Assuming that the force applied by the staff to the handle 22 is F, and the length of the handle 22 is L, the force arm is 1 / 2L, and the moment of force at the fixed point of the handle 22 is M = 1 / 4FL. Figure 12 As shown in Figure 2, the structure diagram of another handle in the prior art, i.e., handle 23, is shown in Figure 2. The two ends of the handle 23 are fixed and installed by two bolts. Assuming that the force applied by the staff to the handle 23 is F, and the length of the handle 23 is L, the force arm is close to 1 / 2L, and the moment of force at each fixed point on the handle 23 is approximately M ≈ 1 / 8FL.

[0071] As shown in Figure 2, the structure diagram of another handle in the prior art, i.e., handle 23, is shown in Figure 2. The two ends of the handle 23 are fixed and installed by two bolts. Assuming that the force applied by the staff to the handle 23 is F, and the length of the handle 23 is L, the force arm is close to 1 / 2L, and the moment of force at each fixed point on the handle 23 is approximately M ≈ 1 / 8FL. Figure 13 As shown in Figure 3, the structure diagram of a handle according to an embodiment of the present application is shown in Figure 3. The two ends of the handle structure are fixed and installed by two bolts. The length of the handle structure is L, and the force applied by the staff to the handle structure is F. The force at the fixed point of the handle is decomposed into two components, F1 and F2. The component F2 does not cause the bolt at the lower left corner of the handle to rotate, and the component F1 does cause the bolt at the lower left corner of the handle to rotate. The perpendicular line drawn from the center of the bolt to the component F1 is the force arm, i.e., L1 in the figure. Obviously, the length of L1 is greater than 1 / 2L. Compared with the handle in the prior art, the force arm is increased under the condition that the total moment of force is constant. Therefore, the moment of force M at the fixed point is less than 1 / 8FL.

[0072] As shown in Figure 3, the structure diagram of a handle according to an embodiment of the present application is shown in Figure 3. The two ends of the handle structure are fixed and installed by two bolts. The length of the handle structure is L, and the force applied by the staff to the handle structure is F. The force at the fixed point of the handle is decomposed into two components, F1 and F2. The component F2 does not cause the bolt at the lower left corner of the handle to rotate, and the component F1 does cause the bolt at the lower left corner of the handle to rotate. The perpendicular line drawn from the center of the bolt to the component F1 is the force arm, i.e., L1 in the figure. Obviously, the length of L1 is greater than 1 / 2L. Compared with the handle in the prior art, the force arm is increased under the condition that the total moment of force is constant. Therefore, the moment of force M at the fixed point is less than 1 / 8FL. Figure 14 As shown in Figure 4, the structure diagram of a handle according to an embodiment of the present application is shown in Figure 4. The force F is decomposed into two components, F3 and F4. Assuming that the point indicated by a1 is the fixed point, and the center of the force of the pulling part 11 is located at the center of the pulling part 11, the distance between a1 and the center of the force is the first force arm. Since the length of the first force arm is greater than 1 / 2L, the force acting on a1 is smaller than the force acting on the handle in the prior art. Then, assuming that the point indicated by a2 is the fixed point, and the distance between a2 and the center of the force is the second force arm, the length of the second force arm is L2, which is greater than 1 / 2L. The force acting on a2 is the component F3 of the force F. As the angle between F and F3 increases within a certain range, F3 decreases continuously. Therefore, the force acting on a2 also decreases.

[0073] The present application completely breaks through the accumulation of the number of bolts and meets the requirement of achieving the same moment of force with smaller force by increasing the force arm.

[0074] In one embodiment, the fixed mounting portion 12 is two, and one end of the two fixed mounting portions 12 protrudes from the handle body 10 by a predetermined length, and the first pre-installation structure is arranged on the fixed mounting portion 12, and when installed, the end of the fixed mounting portion 12 protruding from the handle body 10 is installed away from the lifting direction, at this time, the first pre-installation structure can also prevent the handle structure from being installed in reverse, thereby improving the installation efficiency.

[0075] In one embodiment of the utility model, for single fixed mounting portion 12, the total area of all first connecting structures 13 accounts for 25% to 30% of the area of fixed mounting portion 12.

[0076] Through the above setting, the structural strength of the fixed mounting portion 12 can be ensured, and the service life of the handle structure is further ensured.

[0077] In one embodiment of the utility model, the lifting portion 11 and the fixed mounting portion 12 are of an integrated structure.

[0078] In the embodiment, the lifting portion 11 and the fixed mounting portion 12 are of an integrated structure, and since there is no connection between the lifting portion 11 and the fixed mounting portion 12, the structure has good stability, and secondly, since assembly and connection are not required, the installation process can be simplified, and the installation efficiency is improved.

[0079] In one embodiment of the utility model, the handle body 10 is covered with an insulating sleeve.

[0080] In the embodiment, when the handle structure is installed on the power storage device, the insulating sleeve can prevent current from passing through the human body, reduce the risk of electric shock, and protect personal safety.

[0081] In one embodiment of the utility model, the inner circumferential surface of the insulating sleeve is provided with anti-skid protrusions, and the outer circumferential surface of the handle body 10 is provided with anti-skid grooves.

[0082] Through the above setting, the friction between the inner circumferential surface of the insulating sleeve and the outer circumferential surface of the handle body 10 can be increased, and the sliding of the insulating sleeve relative to the handle body 10 can be avoided.

[0083] From the above description, it can be seen that the above-mentioned embodiments of the utility model achieve the following technical effects: by protruding at least one end of the fixed mounting portion from the handle body by a predetermined length along the first direction, the force arm at the fixed point of the handle body can be increased, according to the definition of the moment, the moment is equal to the product of the force and the force arm, therefore, after the force arm is increased, the anti-deformation moment at the fixed point of the handle structure will be increased under the action of the same force, and the deformation of the handle structure during lifting can be reduced, the probability of deformation and damage of the handle body is reduced, and the service life of the handle structure is improved.
