When the cable is erected, the laying angle or position of the cable is adjusted, the stress on the two force-bearing dragging plates is made as much as possible, the stress on the two ends of the force-bearing piece is made as much as possible, and thus the safety of the force-bearing piece in use is ensured.

Description

Technical Field

[0001] This invention belongs to the field of power cable technology, specifically relating to a load-bearing power fitting with an internal stress viewing window. Background Technology

[0002] In recent years, with the rapid development of power systems and vehicle electrification, the demand for the arrangement and fixing of power cables and automotive electrical components has been increasing, especially in complex structures and space-constrained areas such as seats, thin body panels, or electrical facilities. To ensure the stability and safety of cables, various cable fixing devices have been proposed in the prior art.

[0003] For example, in the automotive seating industry, traditional methods typically use brackets with multiple fastening holes to secure hot wire cables or electrical component cables. This method not only increases installation costs and weight but also leads to reduced production efficiency, complex inventory management, and poor component compatibility because it requires designing separate versions with and without brackets for different seat configurations. To address these issues, a cable retainer that eliminates the need for additional brackets (see CN107112739A) has emerged in the prior art. It achieves direct bundling and securing of cables and wire harnesses through a combination of straps, fastening devices, and cable ties. While this solution simplifies the structure and reduces costs, it still has the following limitations: Lack of stress visualization: The cage only achieves physical fixation and cannot intuitively display the stress state of the cable. Especially in the case of two-point or multi-point support, it is difficult to determine whether each support point is evenly loaded, which can easily lead to local overload or structural fatigue.

[0004] The fixing method is limited: it mainly relies on cable ties for fixing, which is suitable for soft or lightly loaded cables. However, it lacks the fixing rigidity and reliability for power fittings that require high load-bearing capacity and anti-slip properties.

[0005] Difficult to adapt to high load-bearing requirements: Load-bearing hardware in power systems usually bears large tension and complex stress environment, and the mechanical performance and long-term reliability requirements cannot be met by binding alone.

[0006] To address the aforementioned issues, particularly the problems of invisible stress and uneven force distribution in load-bearing fittings in power systems when supported at multiple points, there is an urgent need for a new type of power fitting that can achieve highly reliable fixing and display the internal stress distribution in real time, in order to improve installation accuracy, extend service life, and ensure the safe operation of the power system.

[0007] To address this, the present invention proposes a "load-bearing power fitting with an internal stress viewing window," which aims to achieve intuitive monitoring and balanced load bearing of the cable stress state through a double-position load-bearing arm, a visible stress indicator mechanism, and a one-way locking structure, thereby solving the problems of invisible stress, uneven stress, and insufficient fixing reliability in the prior art. Summary of the Invention

[0008] To address the problems mentioned in the background section, this invention provides a load-bearing power fitting with an internal stress viewing window, which provides intuitive monitoring of the stress state of cables.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a load-bearing power fitting with an internal stress viewing window, comprising a load-bearing frame assembly, wherein two sets of force indicator seat assemblies are slidably arranged inside the load-bearing frame assembly, and a double-position load-bearing arm assembly is provided on the top of the two sets of force indicator seat assemblies, which provides double-position load-bearing support for cables. A locking arm assembly is rotatably arranged on the top of the load-bearing frame assembly, and the locking arm assembly rotates downwards at the top of the load-bearing frame assembly, thereby forming a clamping structure for securing the cable between the locking arm assembly and the double-position load-bearing arm assembly. A locking component is provided on one side of the bottom of the locking arm assembly, which unidirectionally locks the downward rotation of the locking arm assembly, thereby forming a unidirectionally locked clamping structure between the locking arm assembly and the double-position load-bearing arm assembly. The locking of the limiting ratchet can be released by moving the locking pawl.

[0010] In a preferred embodiment of a load-bearing power fitting with an internal stress viewing window, the load-bearing frame assembly includes a housing frame, a stress indicator line, a top housing frame, a horizontal sliding groove, a mounting platform, a square cross arm, and a side housing frame.

[0012] In a preferred embodiment of a load-bearing power fitting with an internal stress viewing window, the double-position load-bearing arm assembly includes a first load-bearing arm, a second load-bearing arm, and a load-bearing slide plate. The first load-bearing arm and the second load-bearing arm form a cross-arm structure.

The bottom of the first load-bearing arm is rotatably mounted on the top ear plate of a set of force indicator seat assemblies, and the bottom of the second load-bearing arm is rotatably mounted on the top ear plate of another set of force indicator seat assemblies.

[0013] In a preferred embodiment of a load-bearing power fitting with an internal stress viewing window, the locking arm assembly includes a locking frame, a first swing arm, a second swing arm, a swing arm shaft, and a limiting ratchet. The top of the first swing arm is rotatably disposed at one end of one side of the locking frame, and the top of the second swing arm is rotatably disposed at the other end of the same side of the locking frame. The swing arm shaft is fixedly disposed at the bottom of the second swing arm, and the limiting ratchet is fixedly disposed at the end of the swing arm shaft away from the second swing arm. The locking arm assembly is rotatably disposed at the side of the top compartment frame near the side compartment frame. At this time, the bottom of the second swing arm is rotatably disposed at one end of one side of the top compartment frame, and the bottom of the first swing arm is rotatably disposed at the other end of the same side of the top compartment frame. The limiting ratchet is located inside the side compartment frame.

[0014] In a preferred embodiment of a load-bearing power fitting with an internal stress viewing window, the locking assembly includes a locking pawl, a pawl push plate, and an abutment spring. The pawl push plate is fixedly mounted on the top of the locking pawl, and the abutment spring is fixedly mounted on the pawl push plate. The locking assembly is located inside a side compartment frame. At this time, the locking pawl is rotatably mounted on the inner end of the side compartment frame, and the two ends of the abutment spring are respectively abutted and fixed to the pawl push plate and the inner side wall of the side compartment frame.

[0015] In a preferred embodiment of a load-bearing power fitting with an internal stress viewing window, the locking pawl and the limiting ratchet are on the same longitudinal plane. Through the push of the pawl push plate by the abutment spring, a one-way limiting engagement structure is formed between the bottom of the locking pawl and the limiting ratchet.

[0016] In a preferred embodiment of a load-bearing power fitting with an internal stress viewing window, the locking frame is located above the double-position load-bearing arm assembly.

[0019] Compared with the prior art, the beneficial effects of the present invention are: 1. The support frame assembly of the present invention has two sets of force indicator seat assemblies slidably arranged inside. The top of the two sets of force indicator seat assemblies is provided with a double-position support arm assembly. The double-position support arm assembly provides double-position support for the cable. The cable applies downward pressure to the first support arm and the second support arm through the support plate. This downward pressure overcomes the elastic force of the push spring. At this time, the two sets of force indicator seat assemblies slide towards the two ends of the square horizontal arm respectively. During the sliding process, the force on the two support plates can be observed by the indication of the force indicator line by the visible arrow. When the cable is laid, the laying angle or position of the cable can be adjusted to make the force on the two support plates as equal as possible, so as to ensure that the force on both ends of the support component is equal, thereby ensuring the safety of the support component during use.

[0020] 2. The top of the support frame assembly of the present invention is rotatably provided with a locking arm assembly. By the downward rotation of the locking arm assembly on the top of the support frame assembly, a clamping structure for fixing the cable is formed between the locking arm assembly and the double support arm assembly. By the downward rotation of the first swing arm and the second swing arm, a clamping structure for the cable is formed between the locking frame and the two support plates on the double support arm assembly, thereby realizing the fixed clamping of the cable.

[0021] 3. A locking component is provided on one side of the bottom of the locking arm assembly of the present invention. The locking component locks the downward rotation of the locking arm assembly in one direction, so that a one-way locking clamping structure is formed between the locking arm assembly and the double-position load-bearing arm assembly. The locking pawl can release the locking of the limiting ratchet by moving the locking pawl. This structure improves the convenience of fixing the line. Attached Figure Description

[0031] In this embodiment, when the indicator slide 201 slides on the square cross arm 106, the two ends of the push spring 203 abut against the inner wall of the indicator slide 201 and the seat frame 101, respectively.

[0032] In this embodiment, the push spring 203 pushes the indicator slide 201, causing the indicator slide 201 to slide into the seat frame 101.

[0033] In this embodiment, by moving the two sets of force indicator seat assemblies 200 inward within the seat frame 101, a raised support arm structure is formed between the first support arm 301 and the second support arm 302.

[0035] In this embodiment, the side sliding arm 205 slides within the transverse sliding groove 104.

[0036] In this embodiment, the tip of the visible arrow 206 points to the force indicator line 102.

The top of the first swing arm 402 is rotatably disposed at one end of one side of the locking frame 401, and the top of the second swing arm 403 is rotatably disposed at the other end of the same side of the locking frame 401. The swing arm shaft 404 is fixedly disposed at the bottom of the second swing arm 403, and the limiting ratchet 405 is fixedly disposed at the end of the swing arm shaft 404 away from the second swing arm 403.

[0041] In this embodiment, the locking arm assembly 400 is rotatably disposed on one side of the top compartment 103 near the side compartment 107.

[0042] In this embodiment, the bottom of the second swing arm 403 is rotatably mounted at one end of one side of the top hopper frame 103.

[0043] In this embodiment, the bottom of the first swing arm 402 is rotatably disposed at the other end of the same side of the top bin frame 103.

[0044] In this embodiment, the limiting ratchet 405 is located inside the side compartment frame 107.

[0045] In this embodiment, the locking bracket 401 is located above the double-position support arm assembly 300.

[0046] In this embodiment, by the downward rotation of the first swing arm 402 and the second swing arm 403, a cable clamping structure is formed between the locking frame 401 and the two load-bearing slides 303 on the double-position load-bearing arm assembly 300.

[0047] In a preferred embodiment, please refer to Figure 8The locking assembly 500 includes a locking pawl 501, a pawl push plate 502, and an abutment spring 503. The pawl push plate 502 is fixedly mounted on the top of the locking pawl 501, and the abutment spring 503 is fixedly mounted on the pawl push plate 502.

[0048] In this embodiment, the locking assembly 500 is disposed within the side compartment frame 107.

[0049] In this embodiment, the locking pawl 501 is rotatably disposed on the inner end of the side compartment frame 107.

[0050] In this embodiment, the two ends of the abutment spring 503 are respectively abutted and fixed to the ratchet push plate 502 and the inner side wall of the side compartment frame 107.

[0051] In this embodiment, the locking pawl 501 and the limiting ratchet 405 are on the same longitudinal plane. Preferably, the locking pawl 501 and the limiting ratchet 405 are arranged opposite each other in a plane perpendicular to the axis of the swing arm shaft 404.

[0052] In this embodiment, the pawl pusher plate 502 is pushed by the abutment spring 503, thereby forming a one-way limiting engagement structure between the bottom of the locking pawl 501 and the limiting ratchet 405.

[0053] When it is necessary to unlock, simply push the pawl push plate 502 upward against the force of the resisting spring 503, so that the locking pawl 501 disengages from the limiting ratchet 405, and the locking bracket 401 can be lifted upward to release the cable.

[0054] The working principle of this invention is as follows: Existing cables, when fixed under load, are mostly subjected to single-point force, which easily leads to uneven force distribution or overload on the load-bearing components, causing wear and tear. To solve these problems, the load-bearing frame assembly 100 of this invention has two sets of force indicator seat assemblies 200 slidably arranged inside. A double-position load-bearing arm assembly 300 is provided on top of the two sets of force indicator seat assemblies 200. The double-position load-bearing arm assembly 300 provides double-position load-bearing support for the cable. Specifically, the load-bearing frame assembly 100 has two sets of force indicator seat assemblies 200. The indicator slide 201 slides on the square horizontal arm 106 through the square groove 204. The double-position load-bearing arm assembly 300 includes a first load-bearing arm 301 and a second load-bearing arm 302. 2. A cross-arm structure is formed between the first support arm 301 and the second support arm 302, and the support slide 303 is provided at the top of both the first support arm 301 and the second support arm 302. The bottom of the first support arm 301 is rotatably mounted on the top ear plate 202 of a set of force indicator seat assemblies 200, and the bottom of the second support arm 302 is rotatably mounted on the top ear plate 202 of another set of force indicator seat assemblies 200. When the indicator slide 201 slides on the square cross arm 106, the two ends of the push spring 203 respectively abut against the inner wall of the indicator slide 201 and the seat frame 101. Through the push action of the push spring 203 on the indicator slide 201, the indicator slide 201 moves towards the seat. The frame 101 slides internally. Through the inward movement of two sets of force-indicating seat assemblies 200 within the seat frame 101, a raised support arm structure is formed between the first support arm 301 and the second support arm 302. In actual use, the cable is placed on the two support plates 303 at the top of the double-position support arm assembly 300. Through the support at two points, the cable is stressed at both ends of the support member. This avoids overloading the support member caused by stress at one point. Simultaneously, to facilitate observation of the stress at the two points, when the indicator slide 201 slides on the square horizontal arm 106, the side sliding arm 205 slides within the horizontal sliding groove 104, providing visual guidance. The tip of head 206 points to the force indicator line 102. When the cable is placed on the load-bearing slide 303, the cable applies downward pressure to the first load-bearing arm 301 and the second load-bearing arm 302 through the load-bearing slide 303. During the downward pressure, it overcomes the force of the push spring 203. At this time, the two sets of force indicator seat assemblies 200 slide towards both ends of the square horizontal arm 106 respectively. During the sliding process, the force on the two load-bearing slides 303 can be observed through the indication of the visible arrow 206 on the force indicator line 102. When the cable is laid, the laying angle or position of the cable can be adjusted to make the force on the two load-bearing slides 303 as equal as possible, so as to ensure that the force on both ends of the load-bearing component is equal, thereby ensuring the safety of the load-bearing component during use.

[0055] Based on the above, in order to solve the problem of cable securing, the support frame assembly 100 of the present invention is rotatably provided with a locking arm assembly 400 at its top. By rotating the locking arm assembly 400 downwards at the top of the support frame assembly 100, a clamping structure for securing the cable is formed between the locking arm assembly 400 and the double-position support arm assembly 300. Specifically, the locking arm assembly 400 includes a locking frame 401, a first swing arm 402, a second swing arm 403, a swing arm shaft 404, and a limiting ratchet 405. The top of the first swing arm 402 is rotatably disposed at one end of one side of the locking frame 401, and the top of the second swing arm 403 is rotatably disposed at the other end of the same side of the locking frame 401. The swing arm shaft 404 is fixedly disposed at the bottom of the second swing arm 403. The limiting ratchet 405 is fixedly installed at the end of the swing arm shaft 404 away from the second swing arm 403. The locking arm assembly 400 is rotatably installed at the side end of the top compartment frame 103 near the side compartment frame 107. At this time, the bottom of the second swing arm 403 is rotatably installed at one end of the side end of the top compartment frame 103, and the bottom of the first swing arm 402 is rotatably installed at the other end of the same side end of the top compartment frame 103. The limiting ratchet 405 is located inside the side compartment frame 107, and the locking frame 401 is located above the double-position support arm assembly 300. By the downward swing rotation of the first swing arm 402 and the second swing arm 403, a cable clamping structure is formed between the locking frame 401 and the two support plates 303 on the double-position support arm assembly 300. In this way, the cable can be fixedly clamped.

[0056] Based on the above, in order to solve the locking problem during cable clamping, a locking component 500 is provided on one side of the bottom of the locking arm assembly 400 of the present invention. The locking component 500 provides one-way locking of the downward rotation of the locking arm assembly 400, thus forming a one-way locking cable clamping structure between the locking arm assembly 400 and the double-position support arm assembly 300. Specifically, the locking component 500 includes a locking pawl 501, a pawl push plate 502, and an abutment spring 503. The pawl push plate 502 is fixedly mounted on the top of the locking pawl 501, and the abutment spring 503 is fixedly mounted on the pawl push plate 502. The locking component 500 is located inside the side compartment frame 107. At this time, the locking pawl 501 is rotatably positioned on the inner end of the side compartment frame 107, and the two ends of the abutment spring 503 are respectively abutted and fixed to the pawl push plate 502 and the inner wall of the side compartment frame 107. Above, the locking pawl 501 and the limiting ratchet 405 are on the same longitudinal plane. Through the push of the pawl push plate 502 by the contact spring 503, a one-way limiting engagement structure is formed between the bottom of the locking pawl 501 and the limiting ratchet 405. In actual use, when the second swing arm 403 and the first swing arm 402 drive the locking frame 401 to rotate and swing down to the position, at this time, through the cooperation of the locking pawl 501 and the limiting ratchet 405, the second swing arm 403 and the first swing arm 402 form a rotating structure that only swings down on one side of the locking frame 401. Through this structure, the locking frame 401 and the load-bearing slide plate 303 are always in a locked state when clamping the cable. That is, a cable fixing structure is formed between the locking frame 401 and the load-bearing slide plate 303 that can only clamp and cannot be released by itself. Through this structure, the convenience of cable fixing operation is improved.

[0057] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
