[0025] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in combination with the specific embodiments of the utility model and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Since the wire hook 2 is currently a separate part and is installed on the chassis 1 by screws, the process of installing the wire hook 2 not only reduces the efficiency of assembly, but also requires two employees to operate together. Integrating the chassis 1 with the wire hook 2 can further improve the assembly efficiency of the electric heating. However, this wiring method is affected by the installation of the screws on the chassis 1, which is not conducive to ensuring the quality of wiring, and will inevitably cause the wire harness to wear or break due to the influence of equipment and process, affecting the safety performance of the wire harness.

[0027] The utility model is now further described in conjunction with the accompanying drawings and embodiments: a chassis structure for quickly assembling an electric heating belt, comprising a chassis 1 and a plurality of wire fixing groups arranged on the chassis 1 along the wiring lines, any one of the wire fixing groups comprising at least two wire fixing hooks 2 with opposite wire fixing directions, any one of the wire fixing hooks 2 being flexibly connected to the chassis 1, and the inner hook height of the wire fixing hook 2 being less than the thickness of the electric heating belt.

[0028] According to the chassis structure of the quick-assembly electric heating belt of the present application, the present application adopts a chassis 1 and a wire fixing hook 2, wherein the wire fixing hook 2 is arranged on the chassis 1. To facilitate quick installation, the wire fixing hook 2 is provided with an opening, which forms a distance slightly smaller than the thickness of the electric heating belt together with the chassis 1 below the wire fixing hook 2. During installation, because the electric heating belt has a certain elasticity, the electric heating belt can be quickly installed into the wire fixing hook 2 through the distance by slightly compressing the electric heating belt. After the electric heating belt is installed into the wire fixing hook 2, the electric heating belt is compressed and rebounded, so that it cannot fall out. The two wire fixing hooks 2 of the same wire fixing group are set in opposite fixing directions. When the electric heating belt is installed on the wire fixing hook 2 of the wire fixing group, the two wire fixing hooks 2 with opposite fixing directions restrict the electric heating belt mutually to prevent the electric heating belt from falling off from the wire fixing hook 2, and the fixing quality of the electric heating belt on the chassis 1 is improved, and the electric heating belt is straightened and tidied.

[0029] According to an embodiment of the present application, the cross-sectional shape of the wire fixing hook 2 along the hook shape is wavy, and one end of the wavy wire fixing hook 2 is integrally fixedly connected to the chassis 1. The setting of the wire fixing hook 2 and the chassis 1 being integrally stamped and formed can avoid the use of screws, ensure the wiring quality of the electric heating belt, and avoid the defect of the electric heating belt being worn out by screw installation, thereby ensuring the installation quality of the electric heating belt.

[0030] At the same time, the hook body of the wire fixing hook 2 of the present application is set to be wavy, and the inner side of the wavy wire fixing hook 2 has wave crests and wave bottoms. When the wire fixing hook 2 is used to install a larger electric heating belt, the electric heating belt will be compressed and close to the wave bottom surface inside the wire fixing hook 2. When it is adapted to a small electric heating belt, the electric heating belt will be positioned by the protruding waves until the minimum belt thickness adapted to the structure is reached, and the inner wave crest of the wire fixing hook 2 contacts the electric heating belt.

[0031] According to one embodiment of the present application, the cross-sectional shape of the wire fixing hook 2 along the hook shape also includes a stopper with an inward protrusion, and the stopper protrudes toward the center of the wire fixing hook 2. When the wire fixing hook 2 is used to install a larger electric heating belt, the electric heating belt will be compressed and tightly attached to the two side surfaces of the stopper of the wire fixing hook 2. When a small electric heating belt is used, the electric heating belt will be positioned by the protruding stopper until the minimum belt thickness adapted to the structure is reached, and the stopper of the wire fixing hook 2 contacts the electric heating belt.

[0032] According to one embodiment of the present application, the wire fixing hook 2 has a first wire fixing block facing inward along the tip of the hook shape and a second wire fixing block on the other side opposite to the first wire fixing block. The first wire fixing block and the second wire fixing block are arranged opposite to each other and form a wire receiving groove with the hook groove inside the wire fixing hook 2. The first wire fixing block and the second wire fixing block are elastic hook-shaped structures. It is convenient to press the electric heating belt wire into the wire fixing hook 2 and prevent the wire from slipping off. When the wire fixing hook 2 is used to install a larger electric heating belt, the electric heating belt will be compressed by the first wire fixing block and the second wire fixing block and be close to the two side surfaces of the first wire fixing block and the second wire fixing block of the wire fixing hook 2. When it is suitable for a small electric heating belt, the electric heating belt will be positioned by the first wire fixing block and the second wire fixing block protruding inward until the minimum belt thickness adapted to the structure is reached, and the first wire fixing block and the second wire fixing block of the wire fixing hook 2 are in contact with the electric heating belt.

[0033] According to an embodiment of the present application, the two wire fixing hooks 2 in opposite directions of any one of the wire fixing groups are spaced apart. To ensure stable assembly, the original single wire fixing hook 2 at each location is replaced with two pairs of wire fixing hooks 2 at a certain distance and in opposite directions to restrict each other.

[0034] According to an embodiment of the present application, two wire fixing hooks 2 with opposite wire fixing directions of any one of the wire fixing groups are arranged in parallel. The two parallel wire fixing hooks 2 can straighten the electric heating belt when installing it.

[0035] According to an embodiment of the present application, the wire fixing hook 2 is provided with a hook groove, and the surface of the hook groove is provided with a plurality of wavy crests and bottoms. The hook body of the wire fixing hook 2 is provided in a wavy shape, and the inner side of the wavy wire fixing hook 2 has crests and bottoms. When the wire fixing hook 2 is used to install a larger electric heating belt, the electric heating belt will be compressed and close to the surface of the bottom of the wave inside the wire fixing hook 2. When the electric heating belt of a small size is used, the electric heating belt will be positioned by the protruding waves until the minimum belt thickness adapted to the structure is reached, and the crest inside the wire fixing hook 2 contacts the electric heating belt.

[0036] According to an embodiment of the present application, the wire fixing hook 2 is provided with an opening, and the opening directions of the wire fixing hooks 2 of any one of the wire fixing groups are arranged in opposite directions. To ensure stable assembly, the original single wire fixing hook 2 at each location is changed to two pairs of wire fixing hooks 2 at a certain distance and with opposite opening directions to restrict each other.

[0037] According to an embodiment of the present application, the chassis 1 is further provided with a plurality of limiting groups, any one of which includes at least one groove 3, the groove 3 being provided on one side of any one of the wire fixing hooks 2 in the wire fixing group, and the groove 3 being provided in parallel with the hook groove of the wire fixing hook 2 in the wire fixing group. When the electric heating belt is installed into the wire fixing hook 2, the electric heating belt will fall into the groove 3 structure below the wire fixing hook 2, and the groove 3 will limit the electric heating belt to prevent displacement of the electric heating belt, and at the same time, it is beneficial to the installation quality of the electric heating belt.

[0038] According to an embodiment of the present application, the chassis 1 is further provided with a plurality of positioning groups, any one of which includes at least two protrusions 4, the protrusions 4 being provided on both sides of the wire fixing hook 2 having a groove 3 in the wire fixing group, and the protrusions 4, the groove 3 and the hook groove being provided in parallel. The electric heating belt will fall into the groove 3 structure below the wire fixing hook 2, and by providing protrusions 4 on both sides of the groove 3, the protrusions 4 will lift up the electric heating belt, so that the electric heating belt can fall into the groove 3 better, and the protrusions 4 assist in positioning the electric heating belt and straightening and arranging the electric heating belt.

[0039] According to an embodiment of the present application, the chassis 1 is further provided with a plurality of positioning groups, any one of which includes at least two protrusions 4, the protrusions 4 being provided on the outside of the groove 3, and the gap between the two protrusions 4 being provided in parallel with the groove 3 and the hook groove. The electric heating belt will fall into the groove 3 structure below the wire fixing hook 2, and by providing two protrusions 4 on one side of the groove 3, the gap between the two protrusions 4 is parallel with the groove 3, the protrusions 4 will further limit the displacement of the electric heating belt, and the two protrusions 4 will assist in positioning the electric heating belt, and straighten and tidy up the electric heating belt.

[0040] According to an embodiment of the present application, the surface of the hook groove is set to be a rough surface. When the surface of the hook groove is set to be a rough surface, when the electric heating belt is installed in the wire fixing hook 2, the friction resistance between the hook groove and the electric heating belt is increased, and the electric heating belt is prevented from sliding out of the opening of the wire fixing hook 2, thereby avoiding the problem of the electric heating belt sliding out of the wire fixing hook 2 and ensuring the wire fixing quality.

[0041] Detailed description of the utility model:

[0042] The overall structure of the device is as follows Figure 1 : The fixing hook 2, the convex block 4, the groove 3 and the chassis 1. The overall structure of the chassis 1 remains unchanged. While the original electric heating belt wiring position remains basically unchanged, the original fixing hook 2 is changed into a pair of fixing hooks 2 with opposite opening directions, which are directly stamped from sheet metal. The hook body of the fixing hook 2 is changed into a wavy shape to adapt to electric heating belts of different specifications. In order to facilitate quick assembly, the fixing hook 2 is provided with an opening, and the side of the fixing hook 2 has a convex point and a groove 3 for auxiliary fixing.

[0043] Electric heating belt assembly operation: Place the chassis 1 steadily, take the electric heating belt, and start installing the electric heating belt according to the required sequence. Slightly bend and compress the electric heating belt when installing it, and insert the electric heating belt from the opening of the wire hook 2. Repeat the previous step to fix the electric heating belt in the reverse wire hook 2, use the protrusion 4 and the groove 3 to assist in positioning, and straighten the electric heating belt.

[0044] Under the condition that the electric heating belt wiring remains basically unchanged, the original single wire hook 2 is changed into a pair of wire hooks 2 formed by sheet metal stamping, and no additional wire hook 2 parts are needed. In order to keep the wire stable and adapt to electric heating belts of various specifications within a certain range, the wire hook 2 is changed into a wave shape while keeping the arc roughly consistent with the original wire hook 2. When the wire hook 2 is matched with a larger specification electric heating belt, the electric heating belt will be compressed and close to the inner wave bottom surface of the wire hook 2. When it is adapted to a small specification electric heating belt, the electric heating belt will be positioned by the protruding waves until the minimum belt thickness adapted to the structure is reached, and the inner wave peak of the wire hook 2 contacts the electric heating belt. In order to facilitate quick installation, the wire hook 2 is provided with an opening, which forms a distance slightly smaller than the thickness of the electric heating belt together with the chassis 1 below the wire hook 2. During installation, because the electric heating belt has a certain elasticity, the electric heating belt can be quickly installed into the wire hook 2 through the distance by slightly compressing the electric heating belt. After the wire hook 2 is installed, the electric heating belt is compressed and rebounds, so that it cannot fall out.

[0045] To ensure a stable assembly, the original single wire hook 2 is replaced by two pairs of wire hooks 2 that are a certain distance apart and have opposite opening directions to restrict each other, and bumps 4 are arranged on both sides of the wire hooks 2 to assist in positioning the electric heating belt.
