Description

Technical Field

[0001] This application relates to the field of installation technology, and in particular to handles and energy systems. Background Technology

[0002] Some heavier equipment (such as inverters, distribution boxes, air conditioner indoor units, flat-screen TVs, audio systems, electric water heaters, range hoods, and disinfection cabinets) is usually wall-mounted and needs to be installed on the wall. However, to save costs, these devices usually do not have handles, making it inconvenient for installers to apply force. In addition, the devices themselves are heavy, and there is a possibility that the installer may slip and drop the equipment during the installation process. Utility Model Content

[0003] Therefore, it is necessary to provide a handle and energy system to address the above problems.

[0004] To address the above problems, this application provides the following technical solution:

[0005] A handle for use in a device having a first locking element and a second locking element, the handle comprising:

[0006] Locking tongue;

[0007] The handle body includes a grip, a first connector, a second connector, and a third connector. The middle portion of the grip forms a force-receiving part for the user to hold. The first connector and the second connector are both fixed to one end of the grip and together with the grip form a first insertion groove for accommodating a first locking member. The third connector and the latch are both located at the other end of the grip and together with the grip form a second insertion groove for accommodating a second locking member. The latch is slidably connected to the grip and relatively away from the force-receiving part. The third connector is fixed to the grip and has a clearance hole to allow the latch to be visible from the outside of the handle body.

[0008] An elastic element is clamped between the gripping member and the locking tongue along the sliding direction of the locking tongue.

[0009] This handle has at least the following beneficial effects:

[0010] Before installing the device onto the wall, the installer inserts their fingers or a tool through the clearance hole and places it against the latch. The latch is then pushed backward (moving towards the resilient element) until the second locking member passes the latch and reaches the first position of the third connector. During this process, the resilient element contracts, tilting the first insertion slot relative to the first locking member. The handle is then moved to allow the first locking member to gradually enter the first insertion slot. The third connector is then pressed against the second locking member. The latch is then released, causing the resilient element to spring back, and the latch returns to its original position under the push of the resilient element. The second locking member is then locked in the second insertion slot. At this point, the handle is installed on the device. During the installation process, the installer can apply force to the device by gripping the support part, which helps prevent the device from slipping and falling during installation. After completing the installation of one of the above devices, the installer can again insert their fingers or auxiliary tools through the clearance hole and place them against the latch, then push the latch back to the first position, and then move the handle away from the second locking member to separate the second insertion slot from the second locking member, and then move the handle away from the first unlocking member to separate the first insertion slot from the first locking member. At this point, the handle can be removed from the above device.

[0011] As shown above, the handle can be detachably connected to the aforementioned equipment. The equipment can be mounted on the wall after the handle is attached, allowing installers to apply force by gripping the load-bearing part, thus preventing installation accidents caused by slipping and dropping the equipment. Furthermore, the handle is reusable, allowing multiple sets of equipment to share the same handle without increasing equipment costs.

[0012] In one embodiment, the first insertion slot includes a first gap and a second gap that are in communication with each other, the second gap being relatively far away from the force-bearing part; the second gap gradually widens along the direction away from the first gap.

[0013] With this configuration, the second gap can guide the first locking member into the first gap, making it easier for the first locking member to enter the first insertion slot and for the handle to be installed on the aforementioned device.

[0014] In one embodiment, the first insertion slot and the second insertion slot are aligned along the length direction of the force-bearing portion.

[0015] This design helps to securely fix the handle to the aforementioned equipment.

[0016] In one embodiment, a limiting portion is fixed on the latch, and the side of the limiting portion away from the elastic member abuts against the gripping member, wherein the elastic member is in a compressed state.

[0017] With this configuration, even when the latch is reset, the elastic element still applies a pushing force to the latch. The elastic element and the gripping element together hold the latch, which helps to ensure the stability of the latch position and improves the reliability of the connection between the handle and the aforementioned equipment.

[0018] In one embodiment, the handle further includes an unlocking member, which includes an extension and an abutment. The extension passes through the clearance hole and partially protrudes from the side of the third connector away from the latch. The abutment is fixed to the extension and located between the extension and the latch. The abutment has a first inclined surface on the side facing the latch, and the latch has a second inclined surface on the side facing the abutment that engages with the first inclined surface. The first inclined surface abuts against the second inclined surface, and the first inclined surface can push the second inclined surface toward the elastic member as the extension approaches the latch.

[0019] With this design, installers can apply force to the extended portion by hand to gradually bring it closer to the latch, causing the first inclined surface to slide relative to the second inclined surface and push the second inclined surface toward the elastic element, thereby retracting the latch. In other words, the handle incorporates the aforementioned auxiliary tool, making it easy for installers to push the latch backward.

[0020] In one embodiment, the extension is conformally adapted to the clearance hole.

[0021] With this design, the clearance hole guides the movement of the extension part, ensuring that the guide part moves in a certain direction. The user only needs to press the extension part to make the latch retract.

[0022] In one embodiment, the protrusion extends beyond the abutment along the length of the force-bearing portion.

[0023] With this design, the abutment part cannot pass through the clearance hole, which prevents the unlocking part from detaching from the third connector through the clearance hole, thereby preventing the unlocking part from being lost.

[0024] This application also provides an energy system, which includes:

[0025] Energy equipment, having a first locking element and a second locking element; and

[0026] In the aforementioned handle, the first locking member is at least partially located within the first insertion slot; the second locking member is at least partially located within the second insertion slot.

[0027] This energy system has at least the following beneficial effects:

[0028] During the installation of energy equipment onto the wall, installers can apply force to the equipment by gripping the load-bearing part, which helps prevent the equipment from slipping and falling during installation. After installing an energy device, the installer can insert their fingers or auxiliary tools through the clearance hole and place them against the latch, then push the latch back to the first position mentioned above. Next, the installer moves the handle away from the second locking member to separate the second insertion slot from the second locking member, and then moves the handle away from the first unlocking member to separate the first insertion slot from the first locking member. At this point, the handle is removed from the energy device. Before installing another energy device onto the wall, the installer inserts their fingers or a tool through the clearance hole and presses it against the latch. Then, they push the latch backward (i.e., the latch moves towards the spring) until the second locking member is allowed to pass over the latch and reach the first position of the third connector. During this process, the spring contracts, causing the first insertion slot to tilt relative to the first locking member. The handle is then moved to allow the first locking member to gradually enter the first insertion slot. The third connector is then pressed against the second locking member. After releasing the latch, the spring rebounds, and the latch is reset under the push of the spring. The second locking member is then locked in the second insertion slot. Thus, the handle is installed on another energy device, achieving the recycling of the handle.

[0029] As shown above, in this energy system, the handle is detachably connected to the energy device. During the installation of the energy device onto the wall, the installer can apply force to the device by gripping the force-bearing part, which helps prevent installation accidents caused by the installer's slipping hand. Moreover, the handle can be reused repeatedly, and multiple sets of energy devices can share the same handle without increasing the cost of the energy devices.

[0030] In one embodiment, the first locking member is located above the second locking member, and the opening of the first insertion slot faces upward.

[0031] This design helps to improve the load-bearing capacity of the handle for energy equipment.

[0032] In one embodiment, the handle is provided in two parts.

[0033] This setup allows one installer to hold both handles with their hands to reliably keep the energy equipment in place, preventing installation accidents caused by the installer slipping and the equipment falling. Attached Figure Description

[0050] See Figures 1 to 8 This application first provides a handle 1, which is applied to a device having a first locking member 21 and a second locking member 22. The handle 1 includes a latch 12, a handle body 11, and an elastic member 13. The handle body 11 includes a grip 114, a first connector 111, a second connector 112, and a third connector 113. The middle portion of the grip 114 forms a force-receiving portion 1141 for the user to grip. The first connector 111 and the second connector 112 are both fixed to one end of the grip 114 and together with the grip 114 form a first insertion groove 15 for accommodating the first locking member 21. The third connector 113 and the latch 12 are both located at the other end of the grip 114 and together with the grip 114 form a second insertion groove 16 for accommodating the second locking member 22. The latch 12 is relatively far from the force-bearing part 1141, and the third connector 113 is relatively close to the force-bearing part 1141. The latch 12 is slidably connected to the grip 114, and the third connector 113 is fixed to the grip 114. The third connector 113 has a clearance hole 1131 to make the latch 12 visible from the outside of the handle body 11. The elastic member 13 is clamped between the grip 114 and the latch 12 along the sliding direction of the latch 12.

[0051] Before installing the device onto the wall, the installer inserts their finger or a tool through the clearance hole 1131 and presses it against the latch 12. Then, the latch 12 is pushed backward (i.e., the latch 12 moves towards the elastic member 13) until the second locking member 22 passes over the latch 12 and reaches the first position of the third connecting member 113. During this process, the elastic member 13 contracts, causing the first insertion slot 15 to tilt relative to the first locking member 21. The handle 1 is then moved to allow the first locking member 21 to gradually enter the first insertion slot 15. The third connecting member 113 is then pressed against the second locking member 22. The latch 12 is then released, and the elastic member 13 springs back, resetting the latch 12 under the push of the elastic member 13. The second locking member 22 is then locked within the second insertion slot 16. At this point, the handle 1 is installed on the device. Figure 1 and Figure 2As shown. During the installation of the above-mentioned equipment onto the wall, the installer can apply force to the equipment by gripping the force-bearing part 1141, which helps to prevent the equipment from falling due to the installer's slippage. After completing the installation of one of the above-mentioned devices, the installer can again pass his fingers or auxiliary tools through the clearance hole 1131 and press them against the locking tongue 12, then push the locking tongue 12 back to the first position, and then move the handle 1 away from the second locking member 22 to separate the second insertion slot 16 from the second locking member 22, and then move the handle 1 away from the first unlocking member 14 to separate the first insertion slot 15 from the first locking member 21. At this point, the handle 1 can be removed from the above-mentioned device.

[0052] As can be seen from the above, the handle 1 can be detachably connected to the aforementioned equipment. The equipment can be mounted on the wall after the handle 1 is attached. This allows installers to apply force to the equipment by gripping the force-bearing part 1141, preventing installation accidents caused by slipping. Furthermore, the handle 1 is reusable, allowing multiple sets of equipment to share the same handle 1 without increasing equipment costs.

[0053] For example, the above-mentioned equipment is an inverter / distribution box / energy storage device / energy storage battery.

[0054] See Figure 4 The gripper 114 has a through hole, and the latch 12 at least partially passes through the through hole and is conformally adapted to the through hole so that the latch 12 is slidably connected to the gripper 114. In other embodiments, a groove may be provided on one of the gripper 114 and the latch 12, and a slide rail may be provided on the other, with the slide rail slidingly engaging with the groove so that the latch 12 is slidably connected to the gripper 114.

[0055] See Figure 5 The first insertion slot 15 includes a first gap 151 and a second gap 152 that are interconnected. The first gap 151 is relatively close to the force-bearing part 1141, and the second gap 152 is relatively far away from the force-bearing part 1141. Along the direction away from the first gap 151, the second gap 152 gradually widens. In this way, the second gap 152 can guide the first locking member 21 into the first gap 151, making it easier for the first locking member 21 to enter the first insertion slot 15 and for the handle 1 to be installed on the aforementioned device.

[0056] See Figure 5 The first insertion slot 15 and the second insertion slot 16 are aligned along the length of the force-bearing part 1141. This facilitates the stable fixing of the handle 1 to the aforementioned device.

[0057] See Figure 4 and Figure 8A limiting part 121 is fixed on the latch 12. The side of the limiting part 121 away from the elastic member 13 abuts against the gripping member 114, and the elastic member 13 is in a compressed state. In this way, when the latch 12 is reset, the elastic member 13 still applies a pushing force to the latch 12. The elastic member 13 and the gripping member 114 jointly clamp the latch 12, which helps to ensure the stability of the latch 12 position and improves the reliability of the connection between the handle 1 and the above-mentioned device.

[0058] For example, the elastic element 13 is a spring or a rubber element.

[0059] See Figure 4 , Figure 5 , Figure 7 and Figure 8 The handle 1 also includes an unlocking member 14, which includes an extension 141 and an abutment 142. The extension 141 passes through the clearance hole 1131 and partially protrudes from the side of the third connector 113 away from the latch 12. The abutment 142 is fixed to the extension 141 and is located between the extension 141 and the latch 12. The side of the abutment 142 facing the latch 12 has a first inclined surface 1421, and the side of the latch 12 facing the abutment 142 has a second inclined surface 122 that cooperates with the first inclined surface 1421. The first inclined surface 1421 abuts against the second inclined surface 122 and partially overlaps with the second inclined surface 122. The first inclined surface 1421 can push the second inclined surface 122 toward the elastic member 13 as the extension 141 approaches the latch 12. In this way, the installer can apply force to the protruding part 141 by hand to gradually bring it closer to the latch 12, thereby causing the first inclined surface 1421 to slide relative to the second inclined surface 122 and push the second inclined surface 122 towards the elastic member 13, thus causing the latch 12 to retract. In other words, the handle 1 has the aforementioned auxiliary tool, making it convenient for the installer to push the latch 12 backward. After the installer releases their grip on the protruding part 141, the elastic member 13 pushes the latch 12 back to its original position.

[0060] contrast Figure 5 and Figure 6 The protrusion 141 is conformally fitted to the clearance hole 1131. In this way, the clearance hole 1131 serves to guide the movement of the protrusion 141, ensuring that the guide moves in a certain direction. The user only needs to press the protrusion 141 to make the latch 12 retract.

[0061] See Figure 5 and Figure 8 The protruding portion 141 protrudes from the abutting portion 142 along the length direction of the force-bearing portion 1141. In this way, the abutting portion 142 cannot pass through the clearance hole 1131, which can prevent the unlocking member 14 from disengaging from the third connector 113 through the clearance hole 1131, thereby preventing the unlocking member 14 from being lost.

[0062] In other embodiments, a pinhole may be provided on the latch 12 relative to the portion away from the elastic member 13. The user inserts a needle through the clearance hole 1131 into the pinhole and then moves the latch 12 backward by moving the needle.

[0063] This application further provides an energy system including an energy device 2 and the aforementioned handle 1. The energy device 2 has a first locking member 21 and a second locking member 22, the first locking member 21 being at least partially located within a first insertion slot 15, and the second locking member 22 being at least partially located within a second insertion slot 16.

[0064] During the installation of the energy device 2 onto the wall, the installer can apply force to the energy device 2 by gripping the force-bearing part 1141, which helps prevent the energy device 2 from falling due to the installer's slippage. After the installation of one energy device 2 is completed, the installer can pass their fingers or auxiliary tools through the clearance hole 1131 and place them against the locking tongue 12, then push the locking tongue 12 back to the first position mentioned above. Afterwards, move the handle 1 away from the second locking member 22 to separate the second insertion slot 16 from the second locking member 22, and then move the handle 1 away from the first unlocking member 14 to separate the first insertion slot 15 from the first locking member 21. At this point, the handle 1 is removed from the energy device 2. Before installing another energy device 2 onto the wall, the installer inserts their finger or a tool through the clearance hole 1131 and presses it against the latch 12. Then, the latch 12 is pushed back (i.e., the latch 12 moves toward the elastic member 13) until the second locking member 22 is allowed to pass over the latch 12 to reach the first position of the third connector 113. During this process, the elastic member 13 contracts, causing the first insertion slot 15 to tilt relative to the first locking member 21. Then, the handle 1 is moved so that the first locking member 21 gradually enters the first insertion slot 15. The third connector 113 is then pressed onto the second locking member 22. After releasing the latch 12, the elastic member 13 springs back, and the latch 12 is reset under the push of the elastic member 13. The second locking member 22 is then locked in the second insertion slot 16. Thus, the handle 1 is installed on the other energy device 2, realizing the recycling of the handle 1.

[0065] As can be seen from the above, in this energy system, the handle 1 and the energy device 2 form a detachable connection. During the installation of the energy device 2 onto the wall, the installer can apply force to the energy device 2 by gripping the force-bearing part 1141, which helps prevent the energy device 2 from falling due to the installer's slip. Moreover, the handle 1 can be reused repeatedly, and multiple sets of energy devices 2 can share the same handle 1 without increasing the cost of the energy device 2.

[0066] For example, energy device 2 is an inverter / distribution box / energy storage device / energy storage battery.

[0067] Preferably, see Figure 3 and Figure 4 The portion of the first locking member 21 located within the first insertion slot 15 is conformally adapted to the first insertion slot 15, and the portion of the second locking member 22 located within the second insertion slot 16 is conformally adapted to the second insertion slot 16. This helps to improve the stability of the connection between the handle 1 and the energy device 2.

[0068] In some embodiments, the first locking member 21 is located below the second locking member 22.

[0069] The first connector 111, the second connector 112, and the gripper 114 that form the first insertion slot 15 are fixed together. Of the third connector 113, the latch 12, and the gripper 114 that form the second insertion slot 16, only the third connector 113 and the gripper 114 are fixed together; the latch 12 and the gripper 114 are slidably connected. Therefore, the first insertion slot 15 has a stronger load-bearing capacity than the second insertion slot 16. Preferably, see [reference needed]. Figures 2 to 5 The first locking member 21 is located above the second locking member 22, and the opening of the first insertion slot 15 faces upward. This helps to improve the load-bearing capacity of the handle 1 on the energy device 2.

[0070] Preferably, the first locking member 21 is along the vertical direction (i.e. Figure 2 The first insertion slot 15 is set with its opening facing directly upwards (vertical direction).

[0071] See Figure 1 and Figure 2 There are two handles 1. In this way, when installing the energy device 2, one installer can hold both handles 1 with both hands to reliably keep the energy device 2 fixed, which helps to prevent the energy device 2 from falling due to the installer's slip.

[0072] Preferably, in Figure 1 and Figure 2 In the illustrated embodiment, two handles 1 are respectively disposed on opposite sides of the energy device 2, and the two handles 1 are positioned facing each other. In these embodiments, more preferably, when the energy device 2 is installed, the length direction of the two handles 1 is aligned with the vertical direction, so that the installer can hold the two handles 1 in a comfortable and natural posture, which is beneficial for the installer to keep the energy device 2 fixed.

[0073] Preferably, in some embodiments, the two handles 1 can be located on the same side of the energy device 2, and the two handles 1 are arranged parallel and aligned. In these embodiments, more preferably, when the energy device 2 is installed, the length direction of the two handles 1 is consistent with the vertical direction, so that the installer can hold the two handles 1 stably in a comfortable and natural posture.

[0074] In some embodiments, the two handles 1 may be arranged in a V-shape or an inverted V-shape on both sides of the energy device 2. In other embodiments, the two handles 1 may be arranged in a V-shape or an inverted V-shape on the same side of the energy device 2.

[0075] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0076] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of protection of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the appended claims.
